Description

Technical Field

[0001] The utility model relates to the technical field of jacking pipe installation, and more specifically to an auxiliary fixing device for jacking pipe installation. Background Art

[0002] Pipe jacking installation is an underground pipeline construction technology, which is usually used in the construction of subways, tunnels and other projects. The stability of pipe jacking installation directly affects the quality of the project. If the position of the pipe jacking is unstable, it may have a negative impact on the entire project. Therefore, auxiliary fixing devices can help ensure the accuracy and consistency of pipe jacking installation and improve the quality of the project. When constructing pipe jacking, multiple pipe jackings are connected by placing one pipe jacking and then plugging another pipe jacking with a forklift. This can easily cause the two pipe jackings to be misaligned when connected and it is difficult to align and install them in one go.

[0003] In view of the above problems, with regard to the technical problem of the inconvenience of the existing top pipe installation docking, after a lot of searches, a top pipe installation auxiliary fixing device with patent number CN220204882U was found, which specifically relates to the field of top pipe auxiliary devices, including a device body, a connecting plate is arranged below the device body, a moving wheel is arranged below the connecting plate, a cylinder is arranged above the device body, and a pressure plate is arranged below the cylinder. After the top pipe is placed on the guide rail, the device is moved above the top pipe, and the pressure plate is driven downward by the cylinder. After the pressure plate contacts the top pipe, it is fixed, and then the second motor of the clamping mechanism on both sides is started to drive the telescopic rod to extend to the top pipe, thereby driving the clamping plate to clamp the top pipe, and then the forklift is used to push the installed top pipe forward, so that the two top pipes can be conveniently plugged and installed. The device is started by the first motor to drive the screw to rotate, and the sliding rod can drive the moving block of the clamping mechanism to move up and down, which can adapt to different top pipe installation heights; however, the technical solution provided by the patent has the following problems:

[0004] (1) When clamping the top pipe, it is necessary to clamp the top first, and then clamp the left and right ends. Although it can play a clamping role, the contact surface of the top pipe is still insufficient, causing inconvenience;

[0005] (2) When clamping the top pipe, the multiple clamping parts need to be adjusted and raised and lowered individually, and they need to be coordinated, making the clamping process not quick and convenient.

[0006] The utility model can improve the clamping contact area of ​​the jacking pipe and increase the friction force, so that the jacking pipe is more stable after clamping, and can complete the whole clamping process at one time without step-by-step, thus simplifying the operation steps.
