Novel guide rail for replacing pipe jacking machine in relay well and quickly assembling head of pipe jacking machine

Abstract

The invention discloses a novel guide rail for replacing a pipe jacking machine in a relay well and quickly assembling a head of the pipe jacking machine. A guide rail connecting joint structure is adopted to realize fast assembling and disassembling of the rail and avoid assembling and disassembling of a guide rail of a traditional pipe jacking machine head through nuts and bolts. The novel guiderail is simple and stable in structure, the assembling and disassembling speed of the rail is high, and the construction efficiency is greatly improved. Meanwhile, a telescopic adjusting rod, a supporting connecting telescopic rod and a lifting structure are adopted, the novel guide rail can be adjusted according to different pipe jacking machine head specifications, and the situation that the guide rail of the traditional pipe jacking machine head needs to be disassembled and replaced according to different pipe jacking machine head specifications is avoided. The novel guide rail does not need to be disassembled, specifications can be switched through manual control, and thus the novel guide rail greatly improves the construction efficiency. A placement guide rail adjusting hinge and ahydraulic telescopic rod are arranged, inclined drilling installation of a pipeline can be conducted, and the limitation of the guide rail of the traditional pipe jacking machine head can not realizeinclined drilling installation of the pipeline is solved.

Description

technical field [0001] The invention belongs to the technical field of engineering equipment; in particular, it relates to a novel guide rail for quickly assembling a head of a pipe jacking machine for replacing a pipe jacking machine in a relay well. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After one section of pipe has been jacked into the soil layer, the second section of pipe will continue to be jacked. Its principle is to push the tool pipe or roadheader from the working pit through the soil layer to the receiving pit by means of the thrust of the mai...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of guide rail for quickly assembling the head of the pipe jacking machine in relay wells to replace the pipe jacking machine head, so as to solve the problem that the existing guide rail needs to be replaced continuously according to the replacement of the pipe jacking machine head. The connection and installation are troublesome and the existing guide rails are difficult to construct for the pipelines that need to be installed at an angle.
