Detailed Description
The core of the utility model is to provide a unload arm rotary joint maintenance device, can realize conveniently and fast ground that unload arm rotary joint is disassembled the maintenance and is repacked fast safely.
In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides a maintenance device for a rotary joint of a discharging arm, which includes a support body, a fixing frame 2, a dismounting frame 1 and a driving device 3, wherein the support body supports other mechanisms on the maintenance device. The fixing frame 2 and the disassembling frame 1 are respectively arranged at two sides of the support body, the fixing frame 2 is used for fixing the rotary joint 4 when the balls are disassembled, and the disassembling frame 1 is used for providing connection support when the inner ring of the rotary joint and the outer ring of the rotary joint are separated. The driving device 3 is provided on the dismounting frame 1.
Wherein, the disassembly frame 1 is connected with the outer ring of the rotary joint, and the piston rod of the driving device 3 is used for extruding the inner ring of the rotary joint. The rotary joint is uniformly stressed by the driving device 3.
It should be noted that the rotary joint 4 includes a rotary joint inner ring, a rotary joint outer ring, a track inner ring, balls and a track outer ring which are arranged between the rotary joint inner ring and the rotary joint outer ring from inside to outside in sequence, and a ball plug on the rotary joint outer ring. The end surfaces of the rotary joint inner ring and the rotary joint outer ring are provided with a plurality of bolt holes. When the rotary joint is disassembled, the rotary joint 4 is fixed on the fixing frame 2, the ball plugs are taken down, the balls are disassembled one by one, then the rotary joint is moved to the disassembling frame 1, the inner ring of the rotary joint is pressed through the driving device, and therefore the inner ring and the outer ring of the rotary joint and the inner ring and the outer ring of the track are disassembled step by step, and all disassembly of the rotary joint is completed. Of course, the fixed frame 2 or the detachable frame 1 can also assemble the disassembled rotary joint 4.
Because of unloading arm process line rotary joint track inner and outer lane extension warp, be difficult to dismantle, according to rotary joint overall dimension and structural feature, this scheme provides an unloading arm rotary joint maintenance device, through providing mount 2 and dismantling frame 1 and provide the fixed position of ball in the dismantlement rotary joint 4 respectively and the dismantlement position of separating the 4 inner and outer races of rotary joint, thereby convenient and fast ground realizes unloading arm rotary joint safety disassembly maintenance and quick repacking, because drive arrangement 3 is exerted pressure the atress evenly to rotary joint, the risk of having avoided equipment body and sealed face to destroy, the reliability in the maintenance process has been improved, work efficiency has greatly been improved.
This scheme is still including setting up in the hoist and mount frame 5 at support body top, and hoist and mount frame 5 is last to be set up the coupling mechanism who is used for installing chain block or electric block. When the balls and the roller paths are seriously abraded, the outer ring of the rotary joint is rotated by the chain block or the electric block, and the balls of the rotary joint can be detached one by one.
It can be seen that the end faces of the rotary joints are uniformly stressed by the driving device 3, and the hand chain block or the electric block on the hoisting frame 5 is uniformly stressed on the rotary joints in the radial direction, so that the radial and horizontal stress is uniform when the rotary joints are disassembled, the sealing surface of the rotary joint body is protected from being damaged, and the maintenance time is greatly shortened.
Furthermore, the connecting mechanism is a hanging ring 6 or a supporting steel rail, and provides a mounting position for the chain block or the electric block. As shown in figure 1, the lifting rings 6 are provided in a plurality and are evenly arranged on two sides of the fixed frame and the detachable frame.
In a particular embodiment, the driving means 3 is a hydraulic cylinder or a pneumatic cylinder, in particular a hydraulic jack.
