Hydraulic crane and underground hydraulic support assembly system using the hydraulic crane

Abstract

The invention belongs to construction and assembling equipment for hydraulic brackets of mines, and particularly relates to a hydraulic travelling crane and an underground hydraulic bracket assembling system applying the same. The hydraulic travelling crane comprises a fixed bracket, a sliding bracket and a hoisting unit, wherein the sliding bracket is arranged on the fixed bracket in a sliding way; the hoisting unit is arranged on the sliding bracket and comprises a sling, a movable pulley and a fixed pulley; the movable pulley is arranged in a reciprocating way; the fixed pulley is fixedly arranged or fixedly arranged in an adjustable manner relative to the sliding bracket; the upper end of the sling is fixedly connected with the sliding bracket; the sling bypasses the movable pulley and the fixed pulley in an S shape; and the lower end of the sling is used for connecting a to-be-hoisted component. The equipment can improve the work efficiency, save salary and material cost, increase the economic benefit, simplify the construction procedure, improve the construction efficiency, accelerate the construction progress and greatly improve the construction safety.

Description

technical field [0001] The invention belongs to construction and assembly equipment for mine hydraulic supports, in particular to a hydraulic crane and an underground hydraulic support assembly system using the hydraulic crane. Background technique [0002] With the improvement of mine production capacity and the promotion of full-height mining technology at one time, fully mechanized mining equipment has gradually become large-scale and heavy-duty. A series of large mining height hydraulic supports have become the main frame type of the mine. , the width and the lifting capacity of the inclined shaft cannot meet the requirements of the large mining height hydraulic support, which is transported downhole and directly installed in the cutting hole. The special assembly room with a certain distance from the cutting hole can be installed after assembly, and the assembly of brackets has become an important factor restricting the construction progress of the project. The traditi...

AI Technical Summary

Problems solved by technology

[0004] Problems in the traditional construction process: 1. Each point requires 4-6 hoists, 10-14 operators, a lot of equipment, and a lot of labor; 2. The lifting point of the equipment is fixed, and when fine-tuning front, back, left, and right, it is necessary to use a hand pull With hoists, there are many operating procedures and complicated construction procedures; 3. Every time a part is assembled, it is necessary to lift the parts to be assembled to a certain height, and then transport the assembled parts to the bottom of the parts to be assembled, which requires multiple reverses; 4. Due to many processes and complex procedures, the progress of bracket assembly is slow, which affects the construction period
