According to an embodiment of the invention, the lower surface of the bottom anti-skid support leg 1102 is provided with a plurality of second V-shaped spikes 1105. When the telescopic rod of the bottom antiskid jack 1101 extends out, the bottom antiskid supporting leg 1102 is driven to move downwards along the vertical direction, so that the second V-shaped nail 1105 on the lower surface of the bottom antiskid supporting leg 1102 is in contact with the bottom plate of the working face and presses the bottom plate of the working face.
According to the embodiment of the invention, at least two high-inclination-angle light-weight end hydraulic supports provided by the invention are arranged on one working face.
When the hydraulic support for the high-inclination-angle light-duty end head of the thin coal seam provided by the invention is arranged on a working surface, a top jack telescopic rod at the central position of a top beam 4 is driven to extend through a hydraulic driving system (not shown in the figure), a first V-shaped nail-carrying casting 9 is driven to extend out of the upper surface 401 of the top beam 4 along a first guide cylinder 8, a top V-shaped nail 901 on the upper surface of the first V-shaped nail-carrying casting 9 is in contact with the top plate of the working surface and extrudes the top plate of the working surface, and therefore the friction force between the top beam 4 and the top plate of the working surface is increased.
Meanwhile, the hydraulic driving system drives the first top anti-falling assembly 6 and the second top anti-falling assembly 7 to move upwards along the vertical direction, and the top plate of the working face is extruded. In the embodiment, taking the second top anti-falling assembly 7 as an example, the hydraulic drive system drives the telescopic rod of the top anti-falling jack 701 to extend out, drives the top anti-falling support leg 702 to move upward along the vertical direction, so that the first V-shaped nail 705 on the upper surface of the top anti-falling support leg 702 contacts with the working face top plate and extrudes the working face top plate, thereby increasing the friction force between the top beam 4 and the working face top plate, and realizing passive falling prevention of the top beam 4.
When the hydraulic support for the light end with the large inclination angle of the thin coal seam, provided by the invention, is arranged on a working surface, the hydraulic driving system drives the telescopic rods of the bottom jacks at the two sides of the base 1 to extend out, the second V-shaped nail casting 13 is driven to extend out of the bottom lower surface 101 of the base 1 along the second guide cylinder 12, the bottom V-shaped nail 1301 of the lower surface of the second V-shaped nail casting 13 is in contact with a working surface bottom plate and extrudes the working surface bottom plate, and therefore the friction force between the base 1 and the working surface bottom plate is increased.
At the same time, the hydraulic drive system drives the first bottom anti-skid component 10 and the second bottom anti-skid component 11 to move downwards along the vertical direction, and the bottom plate of the working face is squeezed. In the embodiment, taking the second bottom anti-skid component 11 as an example, the hydraulic driving system drives the telescopic rod of the bottom anti-skid jack 1101 to extend out, and drives the bottom anti-skid supporting leg 1102 to move downwards along the vertical direction, so that the second V-shaped nail 1105 on the lower surface of the bottom anti-skid supporting leg 1102 is in contact with the working surface bottom plate and extrudes the working surface bottom plate, thereby increasing the friction force between the base 1 and the working surface bottom plate and realizing the passive anti-skid of the base 1.
