Problems solved by technology

[0003] When mining coal mines, it needs to be supported by underground support structures. The existing support structures have single functions, generally vertical supports, and the support effect is general. The inclination angle of the top of the coal mine is adjusted for support, and the support effect is general

Embodiment 1

[0028] see figure 1 and figure 2 , the present invention provides an underground multi-angle support structure for coal mine development through improvement, including a support base 1 and a multi-angle support mechanism 4, the top of the support base 1 is locked with the cylinder 2 through bolts, and the top of the cylinder 2 is locked with the cylinder through bolts. The fixed plates 3 are locked to each other, the left and right sides of the multi-angle support mechanism 4 are respectively locked to the fixed plate 3 by bolts, the middle part of the top of the multi-angle support mechanism 4 is locked to the support rod 5 by bolts, and the left and right sides of the multi-angle support mechanism 4 are locked to each other. The bottom of the fixed plate 3 on the side is provided with a cylinder 2, and the height of the cylinders 2 on the left and right sides of the multi-angle support mechanism 4 is consistent, and the left and right sides of the multi-angle support mechan...

Embodiment 2

[0033] The present invention provides an underground multi-angle support structure for coal mine development through improvement. There are chutes on the left and right sides of the support plate 421. The inner wall of the chute is smooth, and the inner wall of the chute is bonded to the connecting rod 426. The movement trajectory of the connecting rod 426 is limited to increase the stability of the movement of the connecting rod 426, and the rotation of the movable tube 425 is restricted. The surface of the straight plate 432 is smooth, and the inner wall of the bottom end of the support block 431 is fitted with the straight plate 432, increasing the stability of the straight plate. 432 to the fixing effect of support block 431.

[0034] The present invention provides an underground multi-angle support structure for coal mine exploitation through improvement, and its working principle is as follows;

[0035]First, before use, the support structure first needs to be installed....

Abstract

The invention discloses an underground multi-angle supporting structure for coal mining. The underground multi-angle supporting structure comprises supporting seats, air cylinders, connecting plates,a multi-angle supporting mechanism and a supporting rod. According to the underground multi-angle supporting structure for coal mining, the multi-angle supporting mechanism is arranged at the top endof the supporting structure, the supporting rod is connected to the middle part of the top end of the multi-angle supporting mechanism, and the middle part of the top end of a coal mine is supported through the supporting rod; inclined plates are arranged on the left side and the right side of the multi-angle supporting mechanism correspondingly, the bottom ends of the inclined plates are supported through supporting mechanisms, and inclined faces on the left side and the right side of the top end of the coal mine are supported through the inclined plates, so that the supporting effect on thecoal mine is improved; and an adjusting mechanism is arranged in the middle part of the top end of the multi-angle supporting mechanism, the left side and the right side of the adjusting mechanism areconnected with the inclined plates through connecting rods correspondingly, and the inclination angle of the inclined plates is adjusted through the adjusting mechanism so that the inclined plates can be conveniently attached to the inclined faces on the left side and the right side of the top end of the coal mine, the stress effect of the inclined plates is improved, and then the coal mine supporting effect is improved.

Description

technical field [0001] The invention relates to the related field of underground support technology, in particular to an underground multi-angle support structure for coal mine exploitation. Background technique [0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to dig underground roadways to mine coal. This is an underground coal mine. [0003] When mining coal mines, it needs to be supported by underground support structures. The existing support structures have single functions, generally vertical supports, and the support effect is general. The inclination angle of the top of the coal mine is adjusted for support, and the support effect is average. Contents of the invention [0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides ...
