Tunneling temporary support device with guide support

Abstract

The invention discloses a tunneling temporary support device with a guide support. The tunneling temporary support device comprises a first support (1), a second support (2), a telescopic component (3), a first telescopic support column (4), a second telescopic support column (5) and a guide column (6), the telescopic component (3) drives the first support (1) and the second support (2) to alternately move forwards, the first telescopic support column (4) supports the first support (1), the second telescopic support column (5) supports the second support (2), the first telescopic support column (4) is hinged to the first support (1), the second telescopic support column (5) is hinged to the second support (2), the guide column (6) is fixedly connected with the first support (1) and / or thesecond support (2), and the mechanical strength of the guide column (6) is higher than that of the first telescopic support column (4) and the second telescopic support column (5). The temporary support device is effectively prevented from toppling over, production safety is improved, and damage to the telescopic support columns is avoided.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a tunneling temporary support equipment with guide supports. Background technique [0002] In the process of mineral mining, it is necessary to use temporary support equipment to support the roof of the tunneling face to prevent the gravel from falling on the roof of the tunneling face and protect the personal safety of the staff. [0003] The usual way of supporting the roof of the excavation face is to lay metal mesh on the top surface of the excavation temporary support equipment, and then push the excavation temporary support equipment against the roof of the roadway work face. In this way, the excavation temporary support equipment plays a supporting role on the roof of the excavation work face, preventing the roof of the excavation work face from collapsing, and the metal mesh on the top surface of the excavation temporary support equipment can prevent the roof of ...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: in the existing excavation temporary support equipment, the first telescopic strut 4 and the second telescopic strut 5 are respectively connected The two brackets 2 are hinged, although it is convenient to install roadway support equipment, when supporting the roof of the excavation face, because the bottom plate of the excavation face is usually uneven or has a slope, the first telescopic pillar 4 and the second telescopic pillar 5 are in contact with the bottom plate. There may be relative sliding between them, so that the first telescopic pillar 4 and the second telescopic pillar 5 slide, causing the excavation temporary support equipment to tilt and gradually fall, endangering the personal safety of the staff, and once the telescopic pillar bends or Broken, expensive to repair
