Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] refer to figure 1 , an underground rapid assembly process of a shielded hydraulic support described in this specific embodiment, the process includes the following steps:

[0021] 1) Specifications and layout of assembly chamber 1: the bracket assembly site is selected in a section of horizontal roadway, the length of the roadway section is ≥15m, the specification of assembly chamber 1 is length×width×height=6×4.8×4m, the assembly chamber 1. Post-back winch A2, post-back winch B3 and post-back winch C4 are respectively installed on the periphery, post-back winch A2, post-back winch B3 and post-back winch C4 are used for single-piece support lifting, and post-back winch A2, post-back winch B3 Connect a 40T chain with a length of about 1m to the hook head of the steel wire rope on the return column winch C4;

[0022] 2) Hoisting system: Three lift...

Abstract

The invention relates to a process for rapidly assembling a shield-type hydraulic support underground. The process comprises the following steps: 1) determination of the specification and layout of an assembly chamber; 2) assembly of a hoisting system; 3) support detachment and fixation; 4) assembly of the detached support in order. The process has the beneficial effects as follows: 1, multiple prop pulling hoists are used as power for support assembly, no physical labor is required except assembly of pin shafts and a micro-adjustment support, besides, workers can shelter in safe places in the lifting process of the support, all links are compact, the efficiency is high, and as is measured, assembly of one support takes about 50 min under normal conditions; 2, with the adoption of the process, the labor intensity of the workers is greatly reduced, the assembly speed is increased, on-site construction safety is guaranteed, and the economic benefits are remarkable.

Description

technical field [0001] The invention relates to an underground rapid assembly process of a shielded hydraulic support. Background technique [0002] The net diameter of the auxiliary shaft shaft of the coal mine is 5.5m. It is equipped with a wide and a narrow double-layer cage. The size of the wide cage is length×width=4.3×1.6m. The displacement quality of the hoist is 13t. Type 42 hydraulic support implements full support management on the roof of the working face. The characteristic parameters of the hydraulic support are shown in the table below: [0003] [0004] It can be seen from the above table that the auxiliary shaft cannot meet the requirements for lowering the entire frame in terms of size and weight. The support can only be disassembled and then lifted and transported, which increases the labor intensity of workers and seriously affects the assembly efficiency and economic benefits. poor. Contents of the invention [0005] The technical problem to be so...
