Problems solved by technology
However, when the existing hydraulic support is in use, the guard plate is controlled to rotate through the hydraulic rod at the bottom of the front beam and supports the inclined plane of the working face, which makes the angle between the hydraulic rod and the guard plate smaller, resulting in the support force of the hydraulic rod The supply is large, the energy consumption is increased, and the support strength is low, and the first hydraulic rod directly supports the roof beam, and the pressure of the roof beam support is the largest, resulting in the hydraulic rod supporting the roof beam being easily damaged by pressure and affecting the hydraulic pressure. The support stability and strength of the bracket

The invention relates to the field of support equipment for coal mining, and discloses a car-type hydraulic support for coal mines, which includes a support and a pushing mechanism. The bottom of the support is provided with an inner groove, and the middle part of the support is provided with a downward A guide groove, and a first wedge-shaped block that moves up and down is movable in the guide groove, and both ends of the first wedge-shaped block extend to the outside of the inner groove at the bottom of the support. The car-type hydraulic support for coal mine is designed through the positioning plate at the bottom of the front beam and the limit plate at one end of the first guard plate, so that the hydraulic support supports from both ends of the second guard plate during support work, and is relatively Compared with the existing one-end support method, the support strength is improved, and the energy consumption loss of hydraulic support is reduced; and the second guard plate is supported by the third hydraulic rod on the limit plate, which can make The second guard plate stably fits the side wall of mining, further ensuring the stability of the hydraulic support support.
Description
technical field [0001] The invention relates to the field of support equipment for coal mine mining, in particular to a car-type hydraulic support for coal mines. Background technique [0002] Hydraulic support is one of the most important equipment in coal mine fully mechanized mining equipment. It is mainly used to support the roof of the underground working face of the coal mine to protect the safety of equipment and personnel. The number of hydraulic supports in a coal mine fully mechanized mining face is about 100. According to the mining height, slope, mineral structure and environment of each coal mine, the hydraulic support is designed and used. The hydraulic support is mainly composed of top beam, front beam, guard plate, cover beam, front connecting rod, rear connecting rod, base, pushing mechanism, other auxiliary devices. However, when the existing hydraulic support is in use, the guard plate is controlled to rotate through the hydraulic rod at the bottom of the...
