Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-Figure 3 The utility model provides a full-section rapid support device suitable for crushing surrounding rocks, including a mobile base 1, a jack 2 is arranged in the middle of the upper surface of the mobile base 1, a support top plate 3 is arranged on the upper end of the jack 2, and the left and right sides of the lower end of the support top plate 3 are hinged with support side plates 5 through hinged plates 4. The setting of the hinged plates 4 enables the support top plate 3 to be connected with the support side plates 5 through the hinged plates 4, and then when the support top plate 3 is subjected to downward pressure, it can be transmitted to the support side plates 5 through the hinged plates 4, so that the support side plates 5 share the force exerted on the support top plate 3, thereby improving the support efficiency. The supporting effect of the top guard plate 3 is that an adjusting mechanism 6 is arranged inside the mobile base 1, and the adjusting mechanism 6 includes a double-axis motor 601, and the double-axis motor 601 is arranged in the middle of the mobile base 1, and the power output end of the double-axis motor 601 is connected to a threaded rod 602 through a coupling transmission, and the circumferential surfaces of the two threaded rods 602 are threadedly connected to L-shaped push-pull plates 603, and the lower end of the L-shaped push-pull plate 603 is abutted against a lifting plate 604, and springs 605 are arranged on both sides of the lower surface of the lifting plate 604, and an anti-slip plate 606 is arranged in the middle of the lower surface of the lifting plate 604;

[0018] It should be noted that a groove is provided in the middle of the upper end of the lifting plate 604. When the two L-shaped push-pull plates 603 are closest to the dual-axis motor 601, the lifting plate 604 is pushed upward by the elastic force of the spring 605, and the upper end of the lifting plate 604 will be inserted into the inside of the movable groove 9, and the corner of the lower end of the two L-shaped push-pull plates 603 away from the dual-axis motor 601 is arc-shaped, and the left and right ends of the middle groove at the upper end of the lifting plate 604 are also arc-shaped, so that when the two L-shaped push-pull plates 603 are away from the dual-axis motor 601, the L-shaped push-pull plates 603 can smoothly squeeze the lifting plate 604 downward, so that the lifting plate 604 drives the anti-slip plate 606 to move downward and contact the ground.

[0019] A battery 11 is disposed in the middle of the upper surface of the mobile base 1, and the battery 11 is disposed on the rear side of the jack 2, and the jack 2 and the dual-axis motor 601 are electrically connected to the battery 11 through a wiring harness;

[0020] It should be noted that the jack 2 and the dual-axis motor 601 are connected to the battery 11, so that the battery 11 can supply power to the jack 2 and the dual-axis motor 601, so that the jack 2 and the dual-axis motor 601 can work smoothly, thereby improving the application scope of this support equipment. In addition, the setting of the electric jack 2 omits the manual operation of the handle, so the working efficiency of the electric jack 2 is extremely high, and it has a higher load-bearing capacity than the ordinary hydraulic jack 2, so that when the electric jack 2 drives the support roof 3 to move upward to support the coal mine tunnel, the support effect is better.

[0021] In this embodiment, preferably, the inner sides of the two supporting side plates 5 are provided with a slide groove 7, and the two L-shaped push-pull plates 603 are slidably installed inside the two supporting side plates 5, respectively. The setting of the slide groove 7 enables the supporting side plates 5 to slide vertically on the L-shaped push-pull plates 603, and then when the L-shaped push-pull plates 603 drive the supporting side plates 5 to move left and right, they will not be affected by the supporting side plates 5, the hinged plates 4 and the supporting top plate 3.

The lower end of each part is threadedly connected to a limiting rod 8, and the lower ends of the two limiting rods 8 are respectively threadedly connected to the lower ends of the two supporting side plates 5. When the limiting rod 8 is screwed out from the inside of the L-shaped sliding plate 603, the supporting side plates 5 can slide vertically on the L-shaped sliding plate 603. When the limiting rod 8 is screwed into the inside of the L-shaped sliding plate 603, the supporting side plates 5 are fixed to the L-shaped sliding plate 603 through the limiting rod 8, and the supporting side plates 5 will not slide vertically on the L-shaped sliding plate 603.

The lower end of the L-shaped push-pull plate 603 is arranged inside the moving groove 9. The setting of the moving groove 9 provides the L-shaped push-pull plate 603 with a movable space, so that the L-shaped push-pull plate 603 can smoothly move horizontally left and right. The upper ends of the lifting plate 604, the spring 605 and the anti-slip plate 606 are all arranged inside the lifting groove 10. The setting of the lifting groove 10 provides the lifting plate 604 with a movable space, so that the lifting plate 604 can smoothly move vertically.

[0023] The working principle and use process of the utility model are as follows: when it is necessary to support the coal mine tunnel, firstly, the upper end of the limit rod 8 is screwed out from the inside of the L-shaped push-pull plate 603, at which time the supporting side plate 5 can slide vertically on the L-shaped push-pull plate 603, and then the double-axis motor 601 is started, and the double-axis motor 601 drives the two threaded rods 602 to rotate, so that the two L-shaped push-pull plates 603 are away from the double-axis motor 601, so that the two L-shaped push-pull plates 603 push the two supporting side plates 5 to the left and right sides, so that the two supporting side plates 5 are away from the jack 2, and because the supporting side plates 5 are connected to the supporting top plate 3 through the hinged plate 4, the two supporting side plates 5 will also move upward for a distance when moving outward, and after the two supporting side plates 5 are respectively in contact with the two side walls of the tunnel, the double-axis motor 601 Stop working, and when the L-shaped push-pull plate 603 moves to both sides, the lifting plate 604 will be squeezed downward, so that the lifting plate 604 drives the anti-slip plate 606 to move downward, and then the lower end of the anti-slip plate 606 abuts against the ground of the tunnel, thereby improving the fixing effect of the mobile base 1 and preventing the mobile base 1 from sliding and affecting the support effect. Then start the jack 2, and the jack 2 drives the support top plate 3 to move upward, so that the support top plate 3 contacts the top surface of the tunnel, so that the support top plate 3 supports the tunnel, and then rotate the limit rod 8 so that the upper end of the limit rod 8 is screwed into the interior of the L-shaped push-pull plate 603, and the L-shaped push-pull plate 603 is limited and fixed, so that the support side plate 5 will not slide vertically on the L-shaped push-pull plate 603, and then it can share the downward pressure on the support top plate 3.
