Coal mine tunnel multi-directional self-moving slipping boot type hydraulic support

Abstract

The invention provides a coal mine tunnel multi-directional self-moving slipping boot type hydraulic support, and belongs to machinery for coal mines. The coal mine tunnel multi-directional self-moving slipping boot type hydraulic support aims at achieving the technical purposes that the hydraulic support can move by itself, and has good stability and variable directions. According to the technical scheme, the hydraulic support comprises a stepping structure, a lifting and top bracing structure, a steering structure and side tilting preventing structures. According to the stepping structure, two rails are arranged in parallel, a support base is put on the two rails, two displacement jacks correspond to the two rails, and a bottom lifting structure is mounted at the front end of the supportbase. The lifting and top bracing structure is mounted on the support base. The steering structure is mounted at the rear end of the support base, and the two sets of side tilting preventing structures are mounted on the two sides of the support base separately. The hydraulic support is used for the underground coal mines and belongs to the machinery for the coal mines.

Description

Technical field [0001] The invention relates to a multi-directional self-moving sliding shoe hydraulic support for coal mine tunnels, which belongs to coal mine machinery. Background technique [0002] With the continuous improvement of coal mine mechanization and the continuous update of coal mining and transportation technology, auxiliary transportation has an increasing impact on mine production. If a mine does not have a suitable auxiliary transportation system, it cannot give full play to the production capacity of the mining face, let alone achieve high production and efficiency. [0003] At present, most mines use traditional equipment train transportation technology that is hauled by traditional rail winches and wire ropes. This transportation method has a single transportation direction, which cannot be turned well during the movement. It is easy to car, fall off, and have poor stability during the movement. Safety hazards also require laying a large number of tracks for ...

If a mine does not have a suitable auxiliary transportation system, it cannot give full play to the production capacity of the mining face, let alone achieve high production and high efficiency

[0003] At present, most mines use the traditional rail winch wire rope traction equipment train transportation technology. This transportation method has a single transportation direction, cannot turn well during the movement process, and is easy to run away during the movement process. Potential safety hazards also require laying a large number of tracks to walk, wasting a lot of manpower, material resources and time. In addition, due to the uneven floor of the underground roadway, the walking guide rails of the underground equipment train set will deviate during the moving process; At least two sets of supports are required in the protective end hydraulic support. During the moving process, the front and rear supports need to move as fulcrums of each other, which takes up a lot of space in the roadway and the work efficiency is not high.
