Timbering device for hydraulic support withdrawing and fully-mechanized mining timbering equipment

Abstract

The invention discloses a timbering device for hydraulic support withdrawing and fully-mechanized mining timbering equipment and relates to the field of coal mine fully-mechanized mining equipment. The invention aims to provide a timbering device for hydraulic support withdrawing and fully-mechanized mining timbering equipment which have the advantages of high mechanization degree, safety and stability, high production efficiency, simple structure, low cost and easy operation. The timbering device for hydraulic support withdrawing comprises a first timbering component, a second timbering component and a push device, wherein one end of the push device is connected with the second timbering component, and the other end of the push device is connected with the first timbering component; the first timbering component comprises a first timbering beam, a first lifting driver and a supporting cross beam; the second timbering component comprises a second timbering beam, a second lifting driver and a base. The fully-mechanized mining timbering equipment disclosed by the invention comprises the timbering device for hydraulic support withdrawing, a shield support and a timbering support, wherein a to-be-withdrawn support and the shield support form a fully-mechanized mining face triangular area; the timbering device for hydraulic support withdrawing is arranged in the fully-mechanized mining face triangular area and on the gob side of the shield support.

Description

technical field [0001] The invention relates to the field of fully mechanized mining equipment in coal mines, in particular to a support device for retracting a hydraulic support and fully mechanized mining support equipment. Background technique [0002] In coal mine production, after the mining of the fully mechanized mining face is completed, it is necessary to retract the equipment such as the hydraulic support of the fully mechanized mining face. After the retreat, single hydraulic props and I-beams (hinged roof beams) are used to support the goaf roof. This process has problems such as high labor intensity, low support strength, low production efficiency, many safety hazards, and uneconomical construction. A series of problems, the retraction of the support of the fully mechanized mining face has always been a weak link and difficulty in the safety management of coal mining enterprises. [0003] In recent years, coal mining enterprises have tackled key problems throug...

Problems solved by technology

[0002] In coal mine production, after the mining of the fully mechanized mining face is completed, it is necessary to retract the equipment such as the hydraulic support of the fully mechanized mining face. After the retreat, single hydraulic props and I-beams (hinged roof beams) are used to support the goaf roof. This process has problems such as high labor intensity, low support strength, low production efficiency, many safety hazards, and uneconomical construction. A series of problems, the retraction of the support of the fully mechanized mining face has always been a weak link and difficulty in the safety management of coal mining enterprises

[0003] In recent years, coal mining enterprises have tackled key problems through a series of independent projects in the production line, and replaced some single pillars with cover supports, which reduced the labor intensity to a certain extent. A complete set of mechanized equipment has not been formed in areas such as roof support
