Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] The core of the present invention is to provide a pipe joint spacing measuring device, which can measure the distance between two adjacent pipe joints through the movement of the pin shaft during use, so that the distance between two adjacent pipe joints can be kept at a safe within distance.
[0030] Another core of the present invention is to provide a pipe jacking machine including the above-mentioned device for measuring distance between pipe sectio...

The invention discloses a pipe jacking machine and a pipe joint distance measuring device thereof. The pipe joint distance measuring device comprises a sleeve fixed to a shield body, a pin shaft arranged in the sleeve and a power component driving the pin shaft to stretch out of the sleeve or retract back. The power part is provided with a stroke sensor used for detecting the extending distance of the pin shaft. According to the pipe joint distance measuring device provided by the invention, the distance between two adjacent pipe joints can be measured and calculated according to the moving distance of the pin shaft, and the pose of the shield body is adjusted, so that the distance between the two adjacent pipe joints meets the requirement. The phenomenon of extrusion damage or sand leakage caused by the fact that the distance between every two adjacent pipe joints does not meet the requirement can be effectively avoided.
Description
technical field [0001] The invention relates to the technical field of pipe jacking machine construction, and more specifically relates to a measuring device for distance between pipe joints. In addition, the present invention also relates to a pipe jacking machine comprising the above-mentioned device for measuring distance between pipe sections. Background technique [0002] When the adjacent tunnel pipe jacking machine is driving forward, there must be a certain safety distance between the pipe joints; if the distance is too small, the existing pipe joints may be squeezed and the structure may be damaged; if the distance is too far, it may cause temporary Sand leakage occurs during the steel structure, which has a certain impact on the safety and progress of shield construction. [0003] To sum up, how to control the distance between adjacent pipe sections is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this...
