Problems solved by technology

[0002] The shield machine generally weighs hundreds of tons. During the construction process, especially when the shield machine enters and exits the receiving or starting hole, after the deviation correction cylinder is locked, its posture is not easy to adjust, and it is generally used to follow the deviation or temporarily weld the support Use a jack to push the seat, and the method of following the deviation will increase the difficulty of follow-up work; welding the support on the shell of the shield machine will damage the structure of the shield machine
At the same time, the lower edge of the shield machine shell is generally lower than the ground of the receiving shaft, which limits the structure of the adjustment device
There is currently no dedicated device

Embodiment 1

[0021] This embodiment provides a height adjustment device for a shield machine to enter and exit a hole, including a base 1, a pair of jacks 2 and a pair of wedge-shaped sliders 3 arranged on the base 1, the base 1 is provided with guide rails 4, wedge-shaped sliders The block 3 can move horizontally along the guide rail 4 under the push of the jack. Further, the base 1 is in the shape of a strip, the wedge-shaped slider 3 and the jack 2 are arranged at both ends of the strip-shaped base in axisymmetric manner, and the wedge-shaped slider 3 is movably embedded in the guide rail 4, and the The two jacks 2 are respectively located outside the two wedge-shaped sliders.

[0022] The base can be an integral structure or a split structure. If a split structure is adopted, the two bases are connected at the end far away from the jack: the two bases can be connected by bolts. The backing plate 5 is provided with a through hole, and the two backing plates are fastened and connected ...

Embodiment 2

[0025] This embodiment provides a height adjustment device for shield tunneling. The design concept is basically the same as that of Embodiment 1. The difference is that in this embodiment, a limit module 8 is added to the base, and the limit module 8 is fixedly connected to the base 1. Above; the jack 2 is located between the limiting module 8 and the wedge-shaped slider 3, and the wedge-shaped slider 3 is movably embedded on the guide rail 4; the limiting module 8 is fixed on the base 1.

Abstract

The invention provides a height adjustment device for shield tunneling machine departure and reception. The height adjustment device comprises a base, a jack and a wedge-shaped slide block, the jack and the wedge-shaped slide block are arranged on the base, the base is provided with a guide rail, and the wedge-shaped slide block can be driven by the jack to move horizontally along the guide rail. According to the height adjustment device for the shield tunneling machine departure and reception, after a shield tunneling machine rectification oil cylinder is locked, by conduct compression and decompression on a hydraulic jack of the adjustment device, the height between a shield tunneling machine and the ground is easily adjusted, the problem of head sinking or tail sinking of the shield tunneling machine departure and reception can be solved, and the height adjustment device is stable and reliable to support, simple in structure, convenient to operate, low in processing cost, and can be repeatedly utilized.

Description

technical field [0001] The technology belongs to the technical field of tunnel engineering construction. More specifically, the technology relates to a device for adjusting the height of the shield machine when the shield machine pushes out of the receiving opening during shield tunnel construction. Background technique [0002] The shield machine generally weighs hundreds of tons. During the construction process, especially when the shield machine enters and exits the receiving or starting hole, after the deviation correction cylinder is locked, its posture is not easy to adjust, and it is generally used to follow the deviation or temporarily weld the support The support is pushed with a jack, and the follow-up method increases the difficulty of follow-up work; welding the support on the shell of the shield machine will damage the structure of the shield machine. At the same time, the lower edge of the shield machine shell is generally lower than the ground of the receivin...
