Roadway advance support disassembling and assembling system and method

Abstract

The invention discloses a roadway advance support disassembling and assembling system and method. A plurality of roadway brackets form a roadway advance support in a roadway. The roadway advance support disassembling and assembling system comprises a ground transport vehicle, and further comprises a head bracket type hydraulic crane and a tail bracket type hydraulic crane which are located at thetwo ends of the roadway advance support; the ground transport vehicle is located below a support channel formed by the roadway advance support; the head bracket type hydraulic crane is used for lifting the roadway brackets, under the disassembly state, at the end of the roadway advance support onto the ground transport vehicle; the ground transport vehicle transports the disassembled roadway brackets to a to-be-mounted area in the tail of the roadway forward support; and the tail bracket type hydraulic crane lifts and mounts the roadway brackets in the to-be-mounted area. The roadway bracketsin the roadway advance support disassembling and assembling system are forwards circularly propelled in a disassembled mode, repeated support damage to a roadway roof is avoided, the workload of forward moving of the advance support is small, and the disassembling, assembling and transportation safety of the roadway brackets is high.

Description

technical field [0001] The invention relates to the technical field of mine underground operations, in particular to a roadway advance support disassembly system and a disassembly method thereof. Background technique [0002] Mine underground mining is to excavate a series of shafts from the ground to the ground. The entire production process is performed underground, and various operating equipment needs to be transported to the underground tunnel for installation and use. Due to the size of the mine roadway and the requirements of the working environment, most of the lifting, transportation, installation and other equipment commonly used in ground construction cannot be used in the mine underground roadway. Common tools for workers in the roadway are simple crowbars, single hydraulic props and chain hoists, etc. When hoisting larger equipment, using these simple tools is time-consuming and laborious. [0003] According to the "Coal Mine Safety Regulations", the trough of ...

Problems solved by technology

There are two main technical schemes for advancing forward support in existing advance support: one is the sequential self-moving method of roadway supports, that is, as the working face advances forward for each cycle, all roadway supports must be unloaded sequentially and moved forward one by one. Move and support once. During the use of this method, all roadway supports must be frequently unloaded, moved, and supported, causing repeated support to the roadway roof and causing great damage to the self-supporting capacity of the roadway rock mass. The frequent forward movement of the support is complicated and requires a lot of work; the other is the disassembly method, which is to continuously remove the last roadway support near the end of the working face in the roadway as the working face advances, and transport it to the roadway support in the advance support section. Install at the front end of

It adopts a monorail sliding crane track under the advance support. The monorail sliding crane track is installed on the movable steel beam connecting the roadway supports on both sides. The dismantled end roadway support moves to the tail through the monorail sliding crane track for installation. When the roadway support slides on the monorail sliding crane track, the movable steel beam will bear a certain downward force, which will weaken the support of the roadway support to the roadway roof. The disassembly and assembly of the beam and the crane track is labor-intensive, and there will be many construction difficulties during hoisting, which makes the shifting time of the roadway support long and inefficient, and also brings safety hazards to the personnel operating under the advanced support
