Strut, support rod top are rotatably connected to rotation axis, and rotation axis one end is operating side, and turntable is arranged in the other end, under turntable is higher than
Half portion bearing shell is arranged with rope body on turntable；
The free end of rope body is connected to lower half bearing shell side, and operating side drives turntable to rotate by rotation axis, makes body of restricting
It tightens and lifts lower half bearing shell upwards；
During body of restricting lifts lower half bearing shell from lower half bearing shell side upwards, lower half axis is tapped from the other side
Watt, so that lower half bearing shell is screwed out centered on axis upwards out of watt slot；
After lower half bearing shell is disengaged out of watt slot, auxiliary device dismounting is removed.
Further, the rotation axis is parallel to the axis setting of lower half bearing shell.
Further, after the rope body is tightened under turntable rotation, perpendicular to the axis of lower half bearing shell.
Further, the operating side includes hand wheel structure.
Further, the rope body is wirerope.
Further, the free end of the rope body is connected with bolt, and the connection type of rope body and lower half bearing shell is to pass through
Bolt is tightened in the internal thread hole of lower half bearing shell side.
Further, the support rod bottom is equipped with pedestal, the setting mounting hole fixed with apparatus body on pedestal.
Further, the free end of the rope body is connect with lower half bearing shell far from the side of support rod.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that
After this method, the construction efficiency of bearing shell dismounting can be greatly promoted, cost of labor is reduced；It also avoids simultaneously
It causes bearing shell to damage after hitting using copper rod, reduces the risk that construction operation causes object strike to injure, it is ensured that construction
Safety.

Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
As described in Figure 1, the structure chart of auxiliary device, including support rod 1 are removed for bearing shell, bottom is installed in 1 lower end of support rod
Seat 2, pedestal 2 are used to support and on the apparatus bodies 10 that are fixed on the outside of bearing shell, several mounting holes 2a is distributed on pedestal 2,
For matching fastener.Support base 3 is arranged in 1 upper end of support rod, and rotation axis 4 is rotatably assorted on support base 3,4 one end of rotation axis
Circular turntable 6 is installed, turntable 6 is circumferential to be arranged wire casing, rope body 7 is arranged in wire casing, the free end for body 7 of restricting is for connecting shaft
Watt, it is provided with bolt；4 other end of rotation axis is operating side and is provided with handwheel 5, for driving rotation axis 4 to rotate.
In conjunction with Fig. 2-4, the dismounting mode for cooperating above-mentioned dismounting auxiliary device to carry out lower half bearing shell 9 is as follows:
S1, after the dismounting of upper half bearing shell, auxiliary device is mounted on the apparatus body 10 in the outside of lower half bearing shell 9,
With fastener by 2 fix in position of pedestal, and preferably guarantee that rotation axis 4 is parallel with the axis of lower half bearing shell 9, turntable 6 and lower half
The axis of internal thread hole 9a line to be cooperated and lower half bearing shell 9 is in vertical relation on portion's bearing shell 9, and the height of turntable 6 is answered
It is higher by lower half bearing shell 9, to realize more stable draw；
S2, the bolt for 7 free end of body connection of restricting is screwed in the corresponding internal thread hole 9a in 9 side of lower half bearing shell (herein
Internal thread hole 9a original be connection upper half bearing shell use), and preferred bolt and pedestal 2 are located at the not ipsilateral of lower half bearing shell 9, more
Meet the movement rule of lower half bearing shell 9；The bolt connecting with rope 7 free end of body can be plain bolt, can also use spiral shell
The form of lifting lug is connect, rope 7 free end of body is tied up on lifting lug.Rope body 7 herein preferably uses wirerope for proof strength.
