The thrust cylinder plays a vital role in the shield machine. It is mainly used to provide the power for the shield machine to move forward. The shield machine is pushed forward in the soil or rock by the extension and contraction of the cylinder. When the shield machine needs to be shut down for a long time for inspection, maintenance or waiting for other operations, in order to prevent the cylinder from accidentally extending and contracting, the corresponding fixing device will be used to fix it to maintain the stability of the shield machine.

[0003] According to the utility model with authorization announcement number CN216895159U, a thrust cylinder fixing device for a shield machine is disclosed. Although the fixing device can realize the simultaneous operation of the two L-shaped rods and the auxiliary mounting mechanism while rotating the first screw rod through the two L-shaped rods and the auxiliary mounting mechanism, thereby realizing effective installation of the cylinder body and avoiding loosening of the cylinder as much as possible, and the two L-shaped clamping rods can be rotated through the provided axle pin, thereby facilitating the placement of the cylinder pump body on the upper surface of the base plate for installation, its structure is only suitable for the disassembled cylinder, and the size of the cylinder that can be limited and adapted is relatively fixed, and there is a lack of flexible fixing structure for cylinders of different sizes that can be flexibly fixed on or off the shield machine, resulting in a relatively limited application scenario of the thrust cylinder fixing device; for this reason, we provide a thrust cylinder fixing device for a shield machine to solve the above problems.

At this time, first, according to the telescopic condition of the cylinder to be fixed, the other hand operates the button controller 204 to control the servo motor 205 to energize and drive the threaded rod 206 to rotate, and then the moving block 207 threadedly connected to the threaded rod 206 slides in the moving shell 1 until the spacing between the two arc frames 201 can adapt to the surface and telescopic end length of the corresponding propulsion cylinder to be fixed, and then the top plate 202 is screwed with a tool with the assistance of the auxiliary bearing 208.

During this period, the button controller 204 controls the servo motor 205 to remain fixed and not rotate, so as to play the role of flexibly fixing cylinders of different sizes on or off the shield machine.
