Alternate circulation self-moving track type hydraulic support in tunnel roadway

Abstract

The invention discloses acrossheading roadway alternating circulation self-moving rail type hydraulic support, and belongs to coal mine machines. The technical problem of providingthe crossheading roadway alternating circulation self-moving rail type hydraulic supportcapable of self-moving and with good stability and varied azimuth is to be solved; according to the technical scheme,the crossheading roadway alternating circulation self-moving rail type hydraulic support comprises a stepping structure, a lifting jacking structure, a steering structure,anti-heel structures, and a traction jack; the stepping structure structurally comprises two parallelly arranged rails,a bracket base is placed on the two rails, two advancing jacks are mounted corresponding to the two rails, two bottom lifting jacks are vertically mounted at the front end of the bracket base, piston rods of the bottom lifting jacksare lowered downward, and rollers are arranged at the end parts; the lifting jacking structure is mounted on the bracket base; a steering structure is mounted atthe front and rear ends of the bracket base are respectively equipped with, and two sets of the anti-heel structures are respectively mounted on both sides of the bracket base, and the traction jack is arranged parallel to the track and used for installing with an equipment train; and thehydraulic support is used in coal mine roadways.

Description

technical field [0001] The invention relates to an alternate circulation self-moving track type hydraulic support in a tunnel roadway, which belongs to coal mine machinery. Background technique [0002] With the continuous improvement of the degree of mechanization of coal mines and the continuous updating of coal mining and transportation techniques, auxiliary transportation has a greater 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 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 the laying of a large number of tracks, which...

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, it is necessary to lay a large number of tracks, which wastes 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
