Description

Technical Field

[0001] The utility model relates to a pipeline component, in particular to a pipeline component for pipe jacking, and belongs to the technical field of pipe jacking. Background Art

[0002] Pipe jacking is a construction process whose tool is called a pipe jacking machine. It avoids the need for ground excavation by jacking pre-laid pipes into the soil, making construction more efficient and lowering costs. It mainly uses the thrust generated by the jacking equipment to overcome the friction between the pipe wall and the soil, and then cooperates with manual or mechanical excavation to ultimately achieve the purpose of jacking multiple pipes into the soil.

[0003] However, traditional jacking pipes are usually welded or bolted with a lifting head so that the jacking pipe can be lifted into the guide rail laid in the working well with the help of lifting equipment. Since the lifting head is perpendicular to the extension direction of the jacking pipe and the lifting head cannot be rotated and retracted to fit the pipe wall, the lifting head will increase the friction resistance between the jacking pipe and the surrounding soil during the jacking construction process, thereby increasing the difficulty of jacking the pipe and affecting the accuracy of the jacking direction. Utility Model Content

[0004] The purpose of the present invention is to provide a pipe component for jacking pipes in order to solve the above-mentioned problems. The steel ring installed on the jacking pipe body enhances the strength of the jacking pipe body and facilitates the installation of a lifting head. The lifting head not only facilitates the lifting equipment to lift the jacking pipe body, but also drives the lifting head to rotate through the rotating shaft to fit with the outer wall of the steel ring after the lifting is completed, thereby avoiding the lifting head affecting the jacking work of the jacking pipe body, making the lifting head more flexible and convenient to use.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a pipe component for jacking pipe, including a jacking pipe body, a steel ring fixedly connected to the jacking pipe body, two fixed blocks fixedly connected to the steel ring, a rotating shaft rotatably connected to the fixed block, the two ends of the rotating shaft are fixedly connected to the same lifting head, a bolt is rotatably connected to the lifting head, and the end of the bolt is threadedly connected to the steel ring.

[0006] Preferably, the steel ring is installed in the middle of the top tube body, and the outer wall of the steel ring is flush with the outer wall of the top tube body.

[0007] Preferably, the two lifting heads are symmetrically distributed about the middle of the jacking pipe body, and a through groove is formed on the lifting heads.

[0008] Preferably, the lifting head is in a rectangular structure as a whole, and second inclined surfaces are provided on both sides of the lifting head.

[0009] Preferably, a countersunk hole is provided on the lifting head, and the bolt is installed in the countersunk hole.

[0010] Preferably, a socket is fixedly connected to the end of the jacking pipe body, and the socket is plugged into an end of the adjacent jacking pipe body on which a socket is not installed.

[0011] Preferably, the radius of the socket is greater than the radius of the jack body, and a first inclined surface is provided on one end of the socket facing the steel ring.

[0012] The beneficial effects of the utility model are as follows: a steel ring is fixedly connected to the jacking pipe body, two fixed blocks are fixedly connected to the steel ring, a rotating shaft is rotatably connected to the fixed block, both ends of the rotating shaft are fixedly connected to the same lifting head, a bolt is rotatably connected to the lifting head, and the end of the bolt is threadedly connected to the steel ring; installing the steel ring on the jacking pipe body can not only increase the strength of the jacking pipe body, but also facilitate the installation of the lifting head, and the lifting head can be rotated by the rotating shaft, which is not only convenient for the lifting equipment to lift the jacking pipe body, but also, after the lifting is completed, the lifting head is driven by the rotating shaft to rotate until it fits with the outer wall of the steel ring, and then the lifting head is further fixed with bolts, thereby avoiding the lifting head affecting the jacking work of the jacking pipe body, making the lifting head more flexible and convenient to use.

[0022] As a technical optimization solution of the present invention, the lifting head 7 is a rectangular structure as a whole, and a second inclined surface 10 is provided on both sides of the lifting head 7; the setting of the second inclined surface 10 has a guiding effect on the lifting head 7, reducing the friction resistance between the lifting head 7 and the surrounding soil, thereby making the jacking pipe body 1 smoother when jacking into the soil.

[0023] As a technical optimization solution of the present invention, a countersunk hole 9 is provided on the lifting head 7 , and the bolt 8 is installed in the countersunk hole 9 ; the countersunk hole 9 is convenient for installing the bolt 8 .
