A kind of jacking pipe jacking equipment

Abstract

The invention discloses pipe jacking equipment, and aims to provide the pipe jacking equipment with variable rotating diameter and an overload protection function. According to the technical scheme, the pipe jacking equipment is characterized by comprising a pipe jacking machine body, a tool bit mechanism which is in transmission connection with the pipe jacking machine body and has variable rotating radius, a crushing mechanism which moves along with the tool bit mechanism, and a feeding mechanism used for conveying obstacles crushed by the crushing mechanism; the tool bit mechanism is linkedwith the crushing mechanism in the process that the rotating radius is increased, and the material grinding gap of the crushing mechanism is reduced; and the tool bit mechanism is linked with the crushing mechanism in the process that the rotating radius is reduced, and the material grinding gap of the crushing mechanism is increased. The pipe jacking equipment is applicable to the technical field of pipe jacking machines.

Description

technical field [0001] The invention relates to the technical field of pipe jacking machines, in particular to a pipe jacking equipment. Background technique [0002] As the demand for underground pipelines is increasing year by year, coupled with the enhancement of people's awareness of environmental protection, pipe jacking technology will play an increasingly important position and role in the construction of underground pipelines. The development of pipe jacking technology is bound to develop in the direction of scale, standardization and internationalization. [0003] The cutter head is the main working part of the pipe jacking machine. During the pipe jacking construction process, the cutter head is driven by an external power source to rotate and continue to jack, so that the working area can obtain holes that can accommodate pipes. Different geological formations should be selected Different cutterheads and cutter configurations, the quality of cutterheads and cutte...

[0003] The cutter head is the main working part of the pipe jacking machine. During the pipe jacking construction process, the cutter head is driven by an external power source to rotate and continue to jack, so that the working area can obtain holes that can accommodate pipes. Different geological formations should be selected Different cutterheads and cutter configurations, the quality of cutterheads and cutter configurations affect the tunneling speed and benefits of pipe jacking, and even directly affect the success or failure of pipe jacking construction. Because the existing cutter head structure design diameter is not variable and lacks overload protection devices , when encountering hard obstacles during the rotation process, the force on the cutter head is relatively large and it is easy to be damaged, and the obstacles with larger particles generated after the obstacles are broken during the rotation process of the cutter head are likely to cause subsequent grinding The feeding device and the feeding device are stuck
