Problems solved by technology

[0003] In the past, the hoisting segment was mostly hoisted by the beam hoisting segment mechanism. Regardless of loading or unloading the segment, it is necessary to manually operate the segment positioning pin to position the segment. The segment hoisting process is cumbersome and may cause work-related injuries to construction workers risk, and increase the work intensity of construction workers

Abstract

The invention relates to a pipe piece hoisting device which is connected to a waling mechanism of a shield heading machine through a hinge. The pipe piece hoisting device comprises a lifting lug support, a connection support and a clamp body, wherein the lifting lug support is connected with the hinge, the connection support is provided with a sliding block and a force transmission groove, the clamp body is of a symmetric clamping jaw structure, and the upper end portion of the clamp body is provided with a force bearing pin shaft and a guide idler wheel. Compared with the prior art, the pipe piece hoisting device is applied to engineering practice, automatic pipe piece hoisting is facilitated, pipe piece assembling and disassembling do no need extra power sources, construction space occupied by engineering equipment is reduced, a pipe piece positioning pin does not need to be operated manually, the probability that occupational injuries are caused due to operation of the pipe piece positioning pin is avoided, requirements of people-oriented work environment are met, work performance is stable, and compared with an original beam pipe piece hoisting mechanism, the pipe piece hoisting device is greatly improved in the terms of pipe piece assembling and disassembling efficiency, occupied construction space and work intensity of constructors.

Description

technical field [0001] The invention relates to the technical field of shield boring machine tunnel construction, in particular to a hoisting segment device. Background technique [0002] During the construction process of the shield tunneling machine, the segments required for tunnel formation need to be lifted by the segment equipment to lift the segments to the assembly position of the segment assembly machine, and then the segments are assembled and formed by the segment assembly machine. The segment is hoisted to the assembly position of the segment assembly machine, and the hoisting segment mechanism is an essential key mechanism. [0003] In the past, the hoisting segment was mostly hoisted by the beam hoisting segment mechanism. Regardless of loading or unloading the segment, it is necessary to manually operate the segment positioning pin to position the segment. The segment hoisting process is cumbersome and may cause work-related injuries to construction workers r...
