Lifting device capable of stably lifting for tunnel construction

Abstract

The invention discloses a lifting device capable of stably lifting for tunnel construction, and belongs to the technical field of tunnel construction machinery. The lifting device capable of stably lifting for tunnel construction comprises a chassis, wherein a lifting seat is arranged above the chassis; first sliding grooves are formed in the opposite surfaces of the lifting seat and the chassis; and first sliding seats are slidably connected in the two first sliding grooves. According to the lifting device capable of stably lifting for tunnel construction provided by the invention, through mutual cooperation of the designed structures such as a first supporting piece, a second supporting piece, a hydraulic cylinder, the first sliding grooves, the first sliding seats, a hydraulic cylinder, a connecting outer barrel, a connecting inner rod, a first supporting spring, an auxiliary guide rail and a main guide rail, the stability of the lifting seat in the ascending or descending process can be guaranteed, a carrying box can be driven to horizontally move on a horizontal line according to construction requirements, and the chassis is still in a static state in the horizontal moving process of the carrying box, so that the stability of the lifting seat and the carrying box can be guaranteed to a certain extent, the movable linear distance of the carrying box can be extended, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction machinery, and in particular relates to a lifting device for tunnel construction capable of smooth lifting. Background technique [0002] The new Austrian method is to make full use of the self-supporting capacity of the surrounding rock and the space constraints of the excavation surface, using anchor rods and shotcrete as the main support means to reinforce the surrounding rock, restrain the relaxation and deformation of the surrounding rock, and through the Measurement and monitoring of surrounding rock and support, guiding the design and construction of underground engineering. [0003] During the tunnel construction process, mechanical parts and construction personnel need to be lifted to a high place for construction. At present, the existing hoisting devices for tunnel construction still have some deficiencies in the process of use. After reaching the height, if you want to mov...

Problems solved by technology

[0004] The object of the present invention is: in order to solve the existing deficiencies in the use of the existing lifting device for tunnel construction, after lifting the mechanical parts for construction and the construction personnel to a height, if they want to move, they need to use The entire lifting equipment is moving, and the ground environment of one side of the tunnel construction is relatively complex, which will affect the overall stability of the lifting equipment, and easily cause safety accidents, and it is impossible to classify and mark the mechanical parts that need to be used, which seriously affects the construction In order to solve the problem of personnel work efficiency, a kind of lifting device for tunnel construction that can carry out smooth lifting is proposed
