Abstract

The invention provides an anti-tilting device and a pipe jacking system. The device comprises at least two arc-shaped bodies, at least two resistance reduction mechanisms and two fastening mechanisms, the arc-shaped bodies are sequentially and detachably connected to form an annular structure with an opening, and the annular structure is arranged at the joint of two adjacent cylindrical bodies in a sleeving mode. The bottoms of the two cylindrical bodies are movably arranged on a guide rail; and the resistance reduction mechanisms are arranged on the inner sides of the arc-shaped bodies in a one-to-one correspondence mode and make contact with the cylindrical bodies so that resistance can be reduced when the two cylindrical bodies move. The two fastening mechanisms are detachably connected with the two arc-shaped bodies arranged at the opening of the annular structure in a one-to-one correspondence mode, and the two fastening mechanisms jointly act to enable the annular structure and the guide rail to be fastened so as to limit the two cylindrical bodies from tilting. According to the anti-tilting device and the pipe jacking system, the annular structure is arranged at the joint of the two adjacent cylindrical bodies in a sleeving mode, the annular structure and the guide rail at the bottoms of the cylindrical bodies are fastened through the combined action of the two fastening mechanisms, and therefore the two cylindrical bodies are continuously limited, and the two cylindrical bodies are prevented from tilting.

Description

technical field [0001] The invention relates to the technical field of pipe jacking, in particular to an anti-lifting device and a pipe jacking system. Background technique [0002] At present, although the pipe jacking technology is relatively mature, during the jacking process, the connection position between the pipe jacking machine and the pipeline or the connection position between the pipelines is easy to deviate, causing the pipe jacking head to warp or the pipe to warp. Sometimes a crane is needed to press the heavy object on the connection position between the pipeline and the pipe jacking head, which is complicated to operate and not convenient for construction. Contents of the invention [0003] In view of this, the present invention proposes an anti-warping device, which aims to solve the problem that the pipe jacking head or the pipe is easy to warp in the prior art. The invention also proposes a pipe jacking system with the anti-lifting device. [0004] The...
