Abstract
The utility model is a kind of crawler crane center steering body shift fork, including turntable, vehicle frame mounting plate and shift fork；Shift fork one end is mounted on by installing axis pin on turntable, and the other end of shift fork is half box-shaped, is freely coordinated with the center steering body mounted on vehicle frame mounting plate upper surface, and in addition to this, shift fork can be formed around installation axis pin rotation, shift fork by thin plate welding.The prior art is compared, the shift fork of the utility model can be around installation axis pin rotation（There is degree of freedom）, therefore shift fork can be compensated automatically due to coordinating deviation caused by manufacture, and shift fork is formed by thin plate welding, light weight is easy to assembly, easy to operate.
Description
Technical field
The utility model is related to a kind of revolving body shift fork, specifically a kind of crawler crane center steering body shift fork belongs to
Technical field of crane equipment.
Background technology
Currently, when crawler crane carries out revolution action, pivoting support will not be turned round with lower part, to avoid pipeline
And electrical harness distorts, and stirs the rotation of center steering body by shift fork and avoids this problem.But due to crawler crane mainframe
Structure is mostly large scale structure, can inevitably there is foozle.This just will appear shift fork and is asked with the appearance cooperation of center steering body block
It inscribes and causes certain anti-work, it is time-consuming and laborious.If by machining the increase for ensureing that manufacturing cost can be caused again.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of crawler crane center steering body group
Fork overcomes the case where shift fork misplaces or interferes with the block on center steering body caused by manufacturing error, and ties
Structure simply easily assembles, easy to use.
To achieve the goals above, the utility model includes turntable, vehicle frame mounting plate and shift fork；Shift fork one end passes through installation
Axis pin is mounted on turntable, and the other end of shift fork is half box-shaped, certainly with the center steering body mounted on vehicle frame mounting plate upper surface
With.
Further, shift fork can be around installation axis pin rotation.
Further, shift fork is formed by thin plate welding.
The advantages of comparison prior art, the utility model, is as follows：
1. shift fork can be around installation axis pin rotation（There is degree of freedom）, therefore shift fork can be compensated automatically due to making
At cooperation deviation,
2. shift fork is formed by thin plate welding, light weight is easy to assembly, easy to operate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of crawler crane center steering body shift fork, including turntable（5）, vehicle frame mounting plate（2）And shift fork（4）
The shift fork（4）One end is by installing axis pin（3）Mounted on turntable（5）On, shift fork（4）The other end be half box-shaped, with peace
Mounted in vehicle frame mounting plate（2）The center steering body of upper surface（1）Freely coordinate.
It is further improved as the utility model, shift fork（4）It can be around installation axis pin（3）Rotation.
It is further improved as the utility model, shift fork（4）It is formed by thin plate welding.
The prior art is compared, in the utility model, shift fork can be around installation axis pin rotation（There is degree of freedom）, therefore shift fork
It can automatically compensate due to coordinating deviation caused by manufacture；In addition to this, shift fork is formed by thin plate welding, light weight, assembly
It is convenient, it is easy to operate.
