Downward extending type lifting equipment for shaft construction and mounting method thereof

Abstract

The invention discloses downward extending type lifting equipment for shaft construction and a mounting method thereof. A power mechanism at the top of a lifting cage drives the lifting cage to lift up and down along a rail, a standard knot extends out and is conveyed to the lower part of the rail through a telescopic platform, so that the rail extends downwards synchronously along with downward excavation of a shaft; and downward extending installation of the rail, personnel ascending and descending, material conveying and equipment transportation are achieved through lifting of the lifting cage, the power mechanism does not need to be arranged on the ground, vertical shaft lifting equipment is fixedly supported through a hanging mechanism and a wall attaching frame, meanwhile, the dead weight and load of the equipment are borne, the structure is simple, operation is convenient, the construction workload can be reduced, energy is saved, the construction cost is reduced, the construction period is shortened, and the safety coefficient is high.

Description

technical field [0001] The invention belongs to the technical field of engineering construction machinery and equipment manufacturing such as shafts, tunnels, shafts, etc., and in particular relates to a descending lifting device for shaft construction and an installation method thereof. Background technique [0002] In the construction of traditional wells, tunnels, shafts and other projects, the excavation is generally carried out from top to bottom. During the excavation process, the vertical transportation of personnel, materials and construction equipment is usually completed by manually building scaffolding stairs. The bottom surface of the shaft is covered with construction, and the vertical transportation equipment is erected after the ground is hardened. There are problems such as potential safety hazards, high physical exertion of personnel, and low construction efficiency. Convenience, economy and efficiency put forward higher requirements; the vertical shaft lift...

AI Technical Summary

Problems solved by technology

[0002] In the construction of traditional shafts, tunnels, shafts, etc., the excavation is generally carried out from top to bottom. During the excavation process, the vertical transportation of personnel, materials and construction equipment is usually completed by manually building scaffolding stairs. The bottom of the shaft is covered with construction, and the vertical transportation equipment is erected after the ground is hardened. There are problems such as potential safety hazards, high physical exertion of personnel, and low construction efficiency. With the rapid development of traffic, the safety of tunnel construction personnel and vertical transportation of goods, Convenience, economy and efficiency put forward higher requirements; the vertical shaft lifting equipment in the prior art generally assembles the lifting track at the wellhead, and then pushes the assembled track downwards as a whole. Bracket system, set the track propulsion power device on the ground, set the cage lifting power device on the cage, and set up a large-density buttress frame, and fix the shaft lifting equipment through the bracket system and the buttress frame. The structure is complex, and at the same time it carries the weight of the equipment and load, high energy and power consumption, large engineering construction workload, cumbersome operation, high cost investment and long time-consuming
