Description

Triangular area self-moving supporting device

Technical Field

The utility model relates to a mining device, concretely relates to combine triangular space self-moving supporting device of adopting withdrawal usefulness.

Background

The stope is also called coal face. Mining of mines is generally from front to back for safety, a roadway is firstly opened to enter a far place of a planned mining area, and a working face during formal mining is called a stope face.

When the mining of the fully mechanized mining face is finished, the hydraulic support needs to be removed and carried to a new place, and the most difficult and dangerous hydraulic support removing link is the top plate supporting problem of the old pond side triangular area after the hydraulic support is removed. At present, the roof support of the domestic triangular area mainly adopts a single body plus wood pile mode, the support process has the defects of high labor intensity, more material consumption and large potential safety hazard, and is a difficult problem in the process of withdrawing a hydraulic support.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel structure, convenient operation, advantages such as safety, work efficiency height, the triangle district support belongs to and is applicable to different coal face, different roof conditions. When the working face is retracted head on, the shield support can be matched with the shield support to remove the support. In order to realize the purpose, the technical scheme of the utility model is that: triangular space is from moving supporting device, including the base, characterized by is provided with many on the base with the stand, but the stand is hydraulic pressure extending structure, and the second is installed at the stand top and is strutted the part, and the telescopic link is installed to base one side, and the base opposite side is provided with the connecting seat, installs the connecting rod on the connecting seat, and the parallel one side of base is provided with first support part.

The first supporting part is arranged on the first base through the first stand column, and a first telescopic rod capable of stretching is arranged on the first base.

The base on be provided with two post nests, fixed mounting has the stand respectively on two post nests, the second is strutted the part side and is provided with flexible roof beam.

The connecting rod is of a segmented structure, two segments of the connecting rod are hinged, one end of the connecting rod is hinged with the connecting seat, and the other end of the connecting rod is hinged with the second supporting part.

1. Only one-time installation is needed, and the valve handle is operated during use, so that the valve is convenient and flexible;

2. the support strength is high, the support area is large, and the forward moving efficiency is high;

3. the emulsion is used as a power source, and the monomer and the wood stack do not need to be carried manually, so that the safety coefficient is high, and the labor intensity is low;

4. after the triangular region support innovation project is put into a production working face for use, the head-on supporting rate (ground pressure supporting efficiency) of the working face is gradually improved. The working face pressure obviously reduces, and the triangular region support can effectively strut the roof of the triangle stress concentration district that faces, greatly improves operating safety factor, and the triangular region support has significantly reduced operating personnel's intensity of labour simultaneously, improves safe production efficiency.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

in the drawings:

1. a first support member; 2. a second support member; 3. a telescopic beam; 4. fixing the cross beam; 5. a telescopic rod; 6. a column; 7. a base.

Detailed Description

The invention will be further described with reference to the accompanying figure 1: triangular space is from moving supporting device, including base 7, characterized by is provided with many on the base 7 with stand 6, and stand 6 is hydraulic telescoping structure, and second support part 2 is installed at 6 tops of stand, and telescopic link 5 is installed to base 7 one side, and the base 7 opposite side is provided with the connecting seat, installs the connecting rod on the connecting seat, and the parallel one side of base 7 is provided with first support part 1.

First support component 1 pass through first stand and install on first base, be provided with the first telescopic link that can stretch out and draw back on the first base. The base 7 on be provided with two post nests, fixed mounting has stand 6 respectively on two post nests, the second is strutted part 2 side and is provided with flexible roof beam.

The main body part of the bracket consists of three parts, namely a base (comprising an upright post), a top beam and side guards (two side wing plates). The working principle is that the push beam is lengthened by 0.8 meter on the original basis, and the push device is connected with the push beam to realize self-moving; processing a column nest on the base, installing two upright columns, and matching with the top beam to serve as a support main body; the base both sides pterygoid lamina, the flexible stability of reinforcing support through the jack.

The use process comprises the following steps:

1. the support placement is matched with the shield support for use, and the support is arranged at the position close to the old pond side and at the distance of about 300mm beside the shield support, as shown in the figure.

2. When the support is removed, the fixed cross beam contracts, and the supporting component 1 supports the position at the rear part of the top beam of the supporting component 2.

3. After the hydraulic support is removed, the control handle is operated to extend the fixed cross beam, then the supporting component 1 is descended, the supporting component 1 is moved forwards to the front end of the top beam of the supporting component 2, and the top plate is lifted and supported. The height of the top plate when the supporting part 2 moves forwards is ensured.

4. And operating the control handle to lower the support part 2, moving the support part forward by a support width, supporting the support part, completing a support withdrawing period, and withdrawing the next support.

1. For a long time, the roof support of the domestic triangular area mainly adopts a single body plus wood pile mode, the support process has high labor intensity, more material consumption and large potential safety hazard, and is a difficult problem in the process of withdrawing the hydraulic support. The triangular area self-moving type supporting bracket is adopted, so that the safety management of the top plate is realized, and the traditional triangular area top plate maintenance mode is changed. Not only the links of the triangular area pillar support and the pillar return are avoided, but also an intrinsically safe environment is created for workers.

2. The labor consumption is low, the work efficiency is high, the requirement for withdrawing the working face support can be met by only 4 workers per shift, the occupied personnel is reduced by 40%, and the labor reduction and efficiency improvement are really realized. The process is simple, the supporting efficiency is high, the fully mechanized coal mining face withdrawing efficiency is doubled, and the safety and reliability are doubled.

3. The successful implementation of the project reduces the workload of maintaining the top plate of the triangular area, reduces the wood consumption and has popularization and application values for withdrawing the bracket under similar conditions.
