Automatic unhooking and hooking device for hoisting of soil collecting carriage in subway shield tunnel construction

Abstract

The invention provides an automatic unhooking and hooking device for hoisting of a soil collecting carriage in subway shield tunnel construction. According to the automatic unhooking and hooking device for hoisting of the soil collecting carriage in subway shield tunnel construction, a first lock body is fixed to the lower portion of a hoisting rod, a second lock body is rotationally connected to the first lock body, a bearing space is formed between a driving part and a driven part of the second lock body, and a lock lug enters the bearing space to push the driving part, and the second lock body rotates; and when a second locking hole rotates to the position of a locking rod, the driving part drives a locking device, and the locking device drives the locking rod to enter the second locking hole. According to the automatic unhooking and hooking device for hoisting of the soil collecting carriage in subway shield tunnel construction, the second lock body makes natural contact with the lock lug in the descending process, connection between the lock bodies and the lock lug is completed, manual operation is not needed, connection is firm and reliable, the construction time is saved, procedure connection is smooth and efficient, construction accidents caused by misoperation are avoided, manpower is saved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of hoisting construction, in particular to an automatic decoupling device for hoisting a soil-collecting car box in the construction of a subway shield tunnel. Background technique [0002] During the construction of urban subway shield tunnels, the most common way to deal with the slag generated during tunnel excavation is to load it into the soil collection box, transport it by rail, and then transport it back into the receiving shaft, and then hoist it to the ground by a hoist or crane. above, and then transported to the waste dump. Wherein for the hoisting work of collecting soil box needs two workers to cooperate lifting driver to finish jointly. The working process is as follows: the workers at the bottom of the well are responsible for hanging the hoisting ring on the hoisting ear of the soil collection box, and then hoisted by the hoisting driver. The following problems exist in the current technology: [00...

AI Technical Summary

Problems solved by technology

[0003] (1) Manual hooking and uncoupling waste construction time and discontinuous process connection;

[0004] (2) It is easy to cause decoupling accidents due to worker's misoperation;

[0005] (3) Manual hooking and uncoupling requires the cooperation of multiple people, and there are certain requirements for the technical level and cooperation of workers;

[0006] (4) Hooking and decoupling need to occupy two construction workers at the same time, wasting manpower
