Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
It as shown in Figs. 1-2, is provided by the utility model a kind of for yawing the dismounting auxiliary mould of clamp, including silk
Thick stick axis 1, handle 2 and casing 3, the lead screw shaft 1 include lead screw section and optical axis section, and described sleeve pipe 3 is sheathed in the lead screw section
And can slidably reciprocate in lead screw section, the handle 2 includes interconnecting piece, and the interconnecting piece is the ring being sheathed in the lead screw section
Shape set 21, the inner wall of the annular sleeve 21 are equipped with the internal screw thread matched with the external screw thread of the lead screw section, the annular sleeve 21
End rotatably connect with the end of described sleeve pipe 3.Specifically, since yaw clamp 5 are generally fixed by 5 bolts, when
When needing to overhaul or dismount yaw clamp 5, bolt is first unclamped into torque with torque spanner (usually hydraulic torque spanner), then
An intermediate bolt is first removed, one end of the lead screw section of screw axis is fitted into the intermediate screw hole in 5 middle position of yaw clamp
(wherein, the external screw thread of lead screw section can be with the screw-internal thread fit of the screw hole), then swing handle 2, make annular sleeve 21 drive casing 3
It is moved to yaw clamp 5 and casing 3 is made to withstand yaw clamp 5, then remove remaining 4 bolt, yaw clamp 5 are just practical by this
Dismounting auxiliary mould provided by novel is controlled, and handle 2 is then loosened, so that yawing clamp 5 and casing 3 slowly to moving down
It is dynamic, it is moved to the repair and maintenance replacement position that can complete clamp mill small cymbals piece.Yaw the installation process and above-mentioned mistake of clamp 5
For journey on the contrary, alignment bolt eye is convenient and efficient, whole operation process is very laborsaving, to complete the maintenance or dismounting of yaw clamp 5.
Further, bearing 4 is also arranged in the lead screw section, the bearing 4 is set to the annular sleeve 21 and casing 3
Between, the annular sleeve 21 and casing 3 are rotatably connected by the bearing 4, it is preferable that the bearing 4 is flat-pushing bearing, institute
It states and is equipped with annular gasket between bearing 4 and described sleeve pipe 3.So, it is ensured that the handle 2 can with flexible rotating and can guarantee
During yaw clamp 5 move downward, described sleeve pipe 3 will not be rotated relative to yaw clamp 5, so that staff only needs
Expending lesser strength can be completed the dismounting of yaw clamp 5.
Further, applying strength for convenience of staff rotates handle 2, and the handle 2 further includes for driving
The handle part of interconnecting piece rotation, the handle part be along the annular sleeve 21 be arranged radially and outer wall with annular sleeve 21
The quantity of the straight-bar 22 being fixedly connected, the preferably described straight-bar 22 is set on same straight line for 2,2 with straight-bar 22.In this way,
Two hands of staff can exert a force respectively in rotation process, facilitate swing handle 2, when staff needs swing handle 2,
Can two hands hold two straight-bars 22 respectively, then rotate backward.
In the present embodiment, since the internal diameter of the threaded hole of the yaw clamp 5 is 30mm, height of the threaded hole apart from ground
For 800mm, therefore the lead screw shaft 1 is sized to: length 800m, diameter 30mm.It should be understood that, in practice of construction
In the process, the lead screw shaft 1 of different length and diameter can be selected according to the practical structures shape of yaw clamp 5 and installation site.This
Outside, the lead screw shaft 1 is divided into two sections by the lead screw section and optical axis section, and the length of the optical axis section is 296.6mm.Due to tearing open
Only yaw clamp 5 need to be declined certain altitude (not exceeding 500mm generally) when dress, therefore optical axis section is set, without will be entire
Lead screw shaft 1 is processed into lead screw section, to save the processing cost of dismounting auxiliary mould provided by the utility model.
As shown in figure 3, for the utility model is applied to the schematic diagram of process that yaw clamp 5 dismount, wherein need by
Yaw clamp 5 are separated from yaw clamp disk 6.
