Technical Field
Technical Field

Background
In the field of accelerators, an accelerator device generally comprises several important components, which require the use of a common support platform or a single support rack to carry the various components and bring them to a predetermined position and height. These stents generally serve two purposes: firstly, the device plays a role of a supporting platform, so that the element is close to an ideal theoretical position; the other is as a fine adjustment system, which allows the collimator personnel to conveniently, quickly and accurately collimate the element to within the required tolerance. Spallation neutron sources are high intensity proton accelerator devices consisting of low energy linacs and fast cycle synchrotrons (RCS rings). The weight of the magnet in the RCS ring is close to 20 tons, the support, adjustment and positioning are realized through a special bracket, and the alignment precision of the magnet is directly influenced by the size of the bracket adjustment essence.

The three layers are usually included, the top layer is responsible for rotary motion, the middle layer is responsible for horizontal and transverse movement, the bottom layer is responsible for horizontal and longitudinal movement, and manual adjustment is adopted for adjustment of each layer of the support. For example, the magnet support of spallation neutron source often adopts a manual adjustment mode, and the position adjustment in the height direction is difficult due to the heavy weight of the magnet. In order to enable the support to be easily adjusted, most supports adopt a worm and gear lifting mechanism. Nevertheless, the maximum adjustment force required is still as high as 60n.m. Meanwhile, in order to reduce the resistance of lifting adjustment, the reduction ratio of the worm gear and the worm is large, and a manual wrench is adopted for adjustment, so that extremely long time and extremely large manpower are required to be consumed. And the magnet support is 4 point support mode, and every supporting point all needs to be adjusted, at the process of magnet support collimation, need adjust 4 supporting points repeatedly to make the magnet support reach final position. In the process of alternately adjusting 4 worm gear elevators, a spanner needs to be pulled and pulled for many times, and the adjusting shafts of the worm gear elevators are aligned, and the same lifting and falling of 4 supporting points of a bracket cannot be guaranteed only by manpower, so that the situation that the lifting of the 4 supporting points of the bracket is asynchronous and the stress of a single worm gear is not uniform and blocked is difficult to avoid.

Detailed Description
The present application is described in further detail below with reference to the accompanying drawings by way of specific embodiments.

The adjusting plate comprises a vertical moving plate 2 and a translation plate 3 which are stacked on the base 1 from bottom to top. A lifting adjusting system for controlling the whole lifting of the vertical moving plate 3 is arranged between the base 1 and the vertical moving plate 2, and a horizontal adjusting system for controlling the horizontal moving plate to move or rotate in the horizontal direction is also arranged between the vertical moving plate 2 and the horizontal moving plate 3. The horizontal adjusting system comprises a horizontal adjusting mechanism 5 for controlling the horizontal moving of the translation plate 3 along the horizontal direction and a longitudinal adjusting mechanism 4 for controlling the horizontal moving of the translation plate 3 along the horizontal and longitudinal directions. The longitudinal adjusting mechanisms are respectively arranged at two sides of the translation plate 3, when the longitudinal adjusting mechanisms at two sides of the translation plate 3 control the translation plate 3 to move along the same direction, the translation plate 3 moves along the horizontal and longitudinal direction, and when the longitudinal adjusting mechanisms at two sides control the translation plate 3 to move along two opposite directions, the translation plate 3 performs horizontal rotation movement within a certain angle range. The upper surface of the translation plate 3 is provided with a plurality of connecting flange seats 31 for bearing corresponding components, and the connecting flange seats 31 bear the weight of the electrical components together in multiple points and fix the components.
As shown in fig. 2 and 4, a boss 30 protruding downward is formed on the lower surface of the translation plate 3, and the boss 30 is in direct contact with the vertical movement plate 2, so that the translation plate 3 is supported on the surface of the vertical movement plate 2. The longitudinal adjusting mechanism is arranged between the translation plate 3 and the vertical moving plate 2, and is respectively arranged at two sides of the boss 30. The boss 30 is recessed from its bottom center surface to form a cavity 301 for receiving a lateral adjustment mechanism. Since the surface of the translation plate 3 needs to bear components with extremely large weight, such as an accelerator leading-out magnet with a weight of 20 tons, great friction exists between the boss 30 and the vertical moving plate 2 when the boss and the vertical moving plate are relatively moved. Since the device is in an accelerator tunnel environment with strong radiation, the conventional grease lubrication mode is easy to fail, and in order to solve the problem, in this embodiment, a slider 32 for reducing friction is fixed to a portion of the boss 30 contacting with the surface of the vertical moving plate 2. The sliding blocks 32 comprise a group of mutually overlapped sliding blocks, one sliding block is fixed on the bottom surface of the boss 30, the other sliding block is fixed on the corresponding position of the top surface of the vertical moving plate 2, and four supporting points are arranged between the boss 30 and the vertical moving plate 2 in the embodiment, and each supporting point is provided with a group of sliding blocks 32.

In this embodiment of the present application, the electric adjusting bracket is mainly used for carrying the accelerator leading-out magnet that needs to be aligned, and its adjusting range is relatively small, so that the area of the sliding block 32 is based on the moving range that can satisfy the translation plate 3, and it is ensured that in the moving process of the translation plate 3, two opposite sliding blocks 32 are always kept in contact with each other.
As shown in fig. 1, the lifting adjustment system comprises four worm gear lifters 6 arranged on the base 1, lifting screws 60 of the worm gear lifters 6 are in contact with the bottom surface of the vertical motion plate 2, and the four worm gear lifters 6 are divided into four supporting points to support the whole vertical motion plate 2. In this embodiment, the components carried by the translation plate 3 are mainly accelerator leading magnets, the translation plate 3 needs to bear the weight of the magnets, and for such bending magnets as leading magnets, in order to make the stress of each supporting point uniform, the connecting lines of the placing positions of the bracket connecting flange seat 31 form a parallelogram. The centroid of the quadrangle coincides with the center of gravity of the magnet. As shown in fig. 3 and fig. 4, the sliding blocks 32 at the bottom of the translation plate 3 correspond to the positions of the four worm and gear lifters 6 in the vertical direction, and are respectively positioned at four corners of the vertical movement plate 2, and the connecting lines of the sliding blocks and the four corners form a rectangle. By adopting the design, the gravity center of the translation plate 3 is overlapped with the geometric center of the connecting line of the sliding blocks 32, meanwhile, the gravity center of the vertical motion plate 2 is overlapped with the geometric center of the connecting line of the four worm and gear lifters 6, so that the bearing capacity of the bracket is improved, and a plurality of reinforcing ribs 33 are arranged inside the boss 30, so that the bending resistance of the translation plate is improved.

Specifically, as shown in fig. 5 and 6, the first fixing portion is a ball screw mounting seat 40 provided with a ball screw 41, and the ball screw mounting seat 40 is fixedly connected with the vertical moving plate 2 through a revolute pair; the first telescopic part is a ball screw 42 matched with the ball screw, one end of the ball screw 42 is meshed with the ball screw 41, and the other end of the ball screw is fixedly connected with the translation plate 3 through a moving pair or a rotating pair. Wherein, hang down and move board 2 and be equipped with the slide bearing 401 of its surface perpendicularly, ball screw mount pad 40 realizes the fixed connection who hangs down and move board 2 through a perpendicular board connecting axle 402 that suits with slide bearing 401, in this application other embodiments, slide bearing 401 and perpendicular move board connecting axle 402 still can be other forms revolute pairs, for example ball screw mount pad 40 through with hang down and move board 2 articulated, realize when translation board 3 moves along horizontal transverse direction, ball screw mount pad 40 can rotate in the direction that is on a parallel with the surface of hang down and move board 2. The ball screw mounting seat 40 is fixedly provided with a stepping motor 404 connected with a speed reducer 403, the speed reducer 403 is connected with the ball screw 41 through a thrust bearing 405, one end of the ball screw 42 is meshed with the end part of the ball screw 41, the other end of the ball screw is fixedly connected with the translation plate 2 through a joint bearing 421, and the joint bearing 421 is sleeved on a translation plate connecting shaft 422 penetrating through the surface of the translation plate 3, so that the fixed connection between the ball screw 42 and the translation plate 3 is realized. The knuckle bearing 421 is fixedly connected with the ball screw 42 through the connecting flange 43.
When the stepping motor 404 drives the ball screw 41 to rotate through the reducer 403 to drive the ball screw 42 to move towards the ball screw mounting seat 40, the ball screw 42 transmits a tensile force to the translation plate 3 through the knuckle bearing 421 and the translation plate connecting shaft 422, so that the translation plate 3 is pulled to move in a horizontal plane. When the ball screws 42 at both sides of the boss 30 pull or push the translation plate 3 in the same direction, the translation plate 3 moves longitudinally in the horizontal plane (the longitudinal direction is the axial direction of the ball screw 42), and when the ball screws 42 at both sides of the boss 30 apply a force to the translation plate 3 reversely, that is, the ball screw 42 at one side pulls the translation plate 3, and the ball screw 42 at the other side pushes the translation plate 3 in the opposite direction, the translation plate 3 rotates in the horizontal plane at this time.
The transverse adjusting mechanism 5 comprises a second fixing part and a second telescopic part, wherein the second fixing part and the second telescopic part are arranged between the two longitudinal adjusting structures 4, the second fixing part is fixedly connected with the vertical moving plate 2 through a spherical pair, one end of the second telescopic part is fixedly connected with the translation plate 3 through the spherical pair, the other end of the second telescopic part is driven by the second fixing part and can reciprocate horizontally and transversely, and accordingly the translation plate 3 is driven to move horizontally and transversely. When the translation plate 3 moves or rotates along the horizontal and longitudinal directions, the second fixing part and the vertical moving plate 2 relatively rotate through the spherical pair connecting the two, and the second telescopic part also relatively rotates with the translation plate 2 through the corresponding spherical pair.
Specifically, as shown in fig. 7, the second fixing portion is a body 51 of the worm gear lifter 50, and the second telescopic portion is a telescopic screw 52 of the worm gear lifter 50. The lower surface of the translation plate 3 is provided with a transverse installation seat 34, the upper surface of the translation plate 2 is provided with a transverse installation seat 35, a machine body 51 of the worm gear and worm lifter 50 is fixedly connected with the transverse installation seat 35 on the upper surface of the translation plate 2 through a joint bearing 510, and the end part of the telescopic screw rod 52 is fixedly connected with the transverse installation seat 34 on the lower surface of the translation plate 3 through another joint bearing 520. The joint bearing 510 is connected with the transverse mounting seat 35 through a connecting flange 511, the joint bearing 520 is connected with the transverse mounting seat 34 through a connecting flange 512, and in order to reduce the influence of the rotation action of the translation plate 3 on the horizontal transverse adjusting mechanism 5, when the horizontal longitudinal adjusting mechanism 4 controls the rotation of the translation plate 3, the rotation center of the horizontal longitudinal adjusting mechanism is coincident with the position of the joint bearing 520 in the vertical direction.

In this embodiment, when the translation plate 3 is adjusted by the horizontal and longitudinal adjustment mechanism 4, the distance between the connection point of the machine body 51 and the vertical movement plate 2 and the connection point of the telescopic screw rod 52 and the translation plate 3 will change slightly, in order to solve this problem, in this embodiment, the joint bearing 510 and the connection point of the vertical movement plate 2 are in clearance fit, and when the horizontal and longitudinal movement of the translation plate 3 exceeds the clearance fit range, the translation plate 3 will move slightly horizontally and laterally under the action of the horizontal and lateral adjustment mechanism, but this slight lateral movement is within the allowable error range of the electric adjustment bracket in the whole adjustment space, so that no influence is made. Similarly, when the translation plate 3 performs horizontal and horizontal adjustment, the horizontal and longitudinal adjustment mechanism can cause the translation plate 3 to generate a tiny longitudinal movement, and the tiny longitudinal movement is also within the allowable error range of the electric adjustment bracket.
