Description

[0001] The invention relates to the technical field of guard net installation, and in particular to a guard net releasing device for stabilizing the slope of an open-pit coal mine. Background Art

[0002] In open-pit coal mining, the exposed cliffs or slopes after mining are prone to collapse or rockfall, posing a great threat to the safety of people and property below. In order to reduce or avoid this threat, a protective net is generally set up on the exposed slope. The protective net is usually a high-strength, corrosion-resistant metal wire. The traditional installation method is manual spreading, which is dangerous and has low spreading efficiency.

[0003] With the development of technology, the throwing method is usually used when spreading the protective net, that is, the protective net is thrown and spread, so as to increase the barrier-free deployment time of the protective net in the air, improve the spreading effect of the protective net, and avoid the situation where it is difficult to spread due to obstacles. However, the release distance and range of the throwing method are difficult to control, and its release accuracy needs to be improved.

The closing cover 202 and the storage box 201 are spliced ​​into a cylindrical shape, which can be rolled up into a cylindrical shape. The cylindrical protective net is placed inside the storage box 201, and the end of the protective net located outside is passed through the net outlet. When the closed cover 202 is rotated to seal the storage box 201, the limit block 303 contacts the edge of the limit groove. As the closed cover 202 falls, the elastic plate is bent under the blocking effect of the limit groove. When the closed cover 202 and the storage box 201 are close to each other, the limit block 303 completely enters the interior of the limit groove, and the elastic plate rebounds to a vertical state. The limit block 303 is wedge-shaped, and its larger side contacts the inner wall of the limit groove. The limit groove limits the limit block 303 and the limit plate 302 to ensure that the closed cover 202 is close to the storage box 201. 01 is closed to prevent the protective net from falling out from the inside of the storage box 201. When the closed cover 202 needs to be opened, the push plate 401 is pressed, which can push the push rod 402 to press the limit block 303, so that the elastic plate is bent, and the limit of the limit block 303 by the limit groove is released.

Traction, the rolled protective net is limited by the frame 1 and the storage box 201, so that the protective net is spread above the coal mine slope. There is a certain height between the clamping plate 602 and the ground, so that there is a certain distance between the protective net and the ground, reducing the obstacles to the spreading of the protective net caused by the protrusions on the ground. At the same time, the connecting spring 503 between the two support plates 502 connects the two crawler walking structures 501, and the two crawler walking structures 501 are close to the ground through the bending of the connecting spring 503.

The electric cylinder 3 703 can drive the brake plate 702 to descend, and the brake plate 702 can press the protective net against the surface of the placement plate 701 to brake it. At this time, the protective net can be pulled by the crawler walking structure 501 to drive the frame 1 to move. When the crawler walking structure 501 drives the protective net to descend along the slope, the brake plate 702 and the placement plate 701 cooperate to press the protective net to a certain extent, so that the protective net is slowly discharged from the storage box 201, thereby preventing the crawler walking structure 501 from descending too quickly and causing rolling and falling.

The crawler walking structure 501 can drive the protective net to climb over the obstacles on the slope. In this process, the motor 1003 drives the reel 1001 to unwind the pull rope 1002, cooperates with the descent of the crawler walking structure 501, and ensures the stability of the crawler walking structure 501.

[0081] After the crawler walking structure 501 pulls the guard net down to a suitable height, the guard net can be simply fixed manually, and then the screw feeding mechanism 803 drives the moving seat 801 and the cutting pliers 802 to move toward the guard net, and the guard net is inside the jaws of the cutting pliers 802. The electric cylinder 3 703 drives the brake plate 702 to descend, and presses the driving plate 804 and the handle of the cutting pliers 802 located above, so that the cutting pliers 802 cuts the guard net, and the screw feeding mechanism 803 drives the cutting pliers 802 to move in a gap, and the electric cylinder 3 703 drives the brake plate 702 to intermittently press the cutting pliers 802, thereby cutting the guard net;
