Description

TECHNICAL FIELD

[0001] The present application belongs to the field of engineering transport trolley, and particularly relates to a water tunnel lining steel pipe transport and installation integrated trolley and a construction method thereof. BACKGROUND

[0002] In order to reduce the influence of route construction on the ground as much as possible, improve the utilization rate of ground and underground land resources, and avoid the influence of tunnels on ground houses, pavements, underground subway tunnels, circuit communication and other municipal tunnels as much as possible, the route is often designed in the deep ground.

[0003] The hydraulic tunnel bears important functions such as water diversion, water transportation and drainage. During construction, the tunnel steel pipe is transported into the tunnel by the trolley, and after contacting the previous section of steel pipe, the position of the steel pipe is changed by transverse movement and height lifting to align with the previous section of steel pipe, and then the steel pipe is welded and processed subsequently.

[0004] At present, the existing trolley has the following deficiencies when transporting and installing the steel pipe in the tunnel: 1. When the trolley transports the steel pipe to the previous section of steel pipe in the tunnel, the port of the steel pipe on the trolley will gradually approach the port of the previous section of steel pipe and eventually collide. Due to the large weight between the trolley and the steel pipe, when the steel pipe on the trolley collides with the previous section of steel pipe, there is a large impact force due to inertia, which may cause adverse effects on the original installed steel pipe, and finally reduce the overall installation quality of the steel pipe in the tunnel. 2. When the steel pipe on the trolley collides with the previous section of steel pipe to align, it is usually measured and observed by eye to determine whether it is aligned. Due to the narrow space and harsh environment in the tunnel, the tool measurement method is not only low in efficiency, but also relatively difficult to operate. SUMMARY

[0043] In order to reduce the difficulty of calibration of two steel pipes, the first sliding assembly 901 drives the transverse plate 903 to move relative to the chassis 1, the pressure detector 908 above the chassis 1 is moved away, so that the steel pipe can be smoothly placed on the limiting frame 8 by external hoisting equipment, at the same time, the steel pipe is lifted to the same as the steel pipe in the tunnel by the hydraulic jack 802, after the steel pipe is placed, the first sliding assembly 901 drives the pressure detector 908 to reset, so that the pressure detector 908 is inserted into the steel pipe, then the positioning assembly 904 works, the positioning assembly 904 can be fixed on the inner wall of the steel pipe, and the transverse plate 903 is forced to be at the same height level as the axis of the steel pipe, at this time, the pressure detector 908 moves and abuts on the inner wall of the steel pipe, the pressure when the inner wall of the steel pipe abuts on the pressure detector 908 is measured, the first motor 906 rotates to drive the pressure detector 908 to rotate, whether the pressure of the pressure detector 908 deviates greatly after rotating one circle is detected, and whether the center line of the transverse plate 903 is at the same position as the axis of the steel pipe is judged reversely. When the steel pipe on the limiting frame 8 is aligned with the previous steel pipe, the alignment of the two steel pipes needs to be detected, the second sliding assembly 905 is elongated to drive the pressure detector 908 to move from the rear steel pipe into the inner wall of the front steel pipe, since the position of the transverse plate 903 relative to the rear steel pipe does not change, when the first motor 906 drives the second telescopic assembly 907 to rotate, the pressure detector 908 moves along the inner wall of the front steel pipe to do circular motion, the pressure on the pressure detector 908 from the inner wall of the steel pipe is measured by the pressure detector 908 (the influence of the gravity of the pressure detector 908 is ignored), if the two steel pipes are not aligned, it indicates that the centers of the two steel pipes are not on the same axis, at this time, the data detected by the pressure detector 908 in a certain area of the front steel pipe and the data measured in the steel pipe on the limiting frame 8 will have a large deviation, the workers can judge whether the two steel pipes are aligned according to the detection data, and adjust the steel pipe on the limiting frame 8 accordingly. If the two steel pipes are aligned, the centers of the two steel pipes are on the same axis, at this time, the pressure data measured by the pressure detector 908 after rotating one circle in the front steel pipe is basically the same as the pressure data measured in the limiting frame 8, then it indicates that the two steel pipes are aligned, the position of the pressure detector 908 in the front steel pipe can be adjusted by the second sliding assembly 905 to repeatedly measure, so as to finally judge whether the two steel pipes are aligned, and subsequent processing can be carried out after confirming the alignment.
