A mining sliding support with adjustable angle telescopic grille tail support

Abstract

The invention discloses a mine slippage support with a landing adjustable-angle stretchable grating type tail support. The mine slippage support solves the problems that in an existing device, a recrement stop plate is short, an overall support is prone to falling, and materials are wasted, and is characterized by further comprising a lower support, an upper support, an angle adjustment device and a stretchable oil cylinder. The upper support is integrally composed of a supporting transverse beam and a plurality of supporting round pipes, the lower support is integrally composed of a supporting transverse beam and a plurality of supporting round pipes, the round pipes of the lower support are connected in the round pipes of the upper support in a penetrated and inserted mode, the upper end of the stretchable oil cylinder is fixed on the transverse beam of the upper support, the lower end of the stretchable oil cylinder is connected to the transverse beam of the lower support through a piston rod, and the upper support is hinged to a top beam through the angle adjustment device. According to the landing adjustable-angle stretchable grating type tail support of the mine slippage support, a frame body can be stabilized and prevented from falling, burying and occupation of gangue of goaf can be prevented, and net paving operation is reduced; the length is adjustable, changes of the thicknesses of a coal seam and changes of inclination angles of the coal seam can be adapted, and the supporting angle can be adjusted according to site requirements; the goaf can be conveniently observed; the mine slippage support is simple in structure, convenient to use, efficient, safe and reliable, and materials are saved.

Description

technical field [0001] The invention relates to a sliding support for mines, more precisely, to a sliding support for mines with a grid structure. Background technique [0002] The sliding support is a kind of mine support equipment between the single pillar and the self-moving hydraulic support. There is only a short gangue board at the end of the general sliding support, and the gangue falling from the goaf is easy to bury the rear column, and even interfere with the pedestrian space, and it is often necessary to lay the net manually, which is inefficient, unsafe, and wastes materials, etc.; The possibility of the support toppling over, especially in the working conditions of the upward mining face, the large-inclination working face, and the leaky area on the roof behind the coal wall, is likely to cause the whole frame to fall, and even bring serious consequences; the stability of a single support is very poor , basically rely on the connection between each other to ach...

Problems solved by technology

There is only a short gangue board at the end of the general sliding support, and the gangue falling from the goaf is easy to bury the rear column, and even interfere with the pedestrian space, and it is often necessary to lay the net manually, which is inefficient, unsafe, and wastes materials, etc.; The possibility of the support toppling over, especially in the working conditions of the upward mining face, the large-inclination working face, and the leaky area on the roof behind the coal wall, is likely to cause the whole frame to fall, and even bring serious consequences; the stability of a single support is very poor , basically rely on the connection between each other to achieve a stable effect. If one plane is skewed, it is easy to bring about a chain reaction
