[0002] Mining will face the risk of collapse, so it is necessary to support the already excavated mines to reduce the risk of collapse.

[0003] However, even if support measures are adopted, the mine will still be at risk of collapse due to its own structural instability, which will lead to mining accidents. In other words, mine collapse is difficult to avoid artificially, so there is a need for a device that can provide protection to miners in the event of a collapse. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes an anti-collapse mining support device, which can provide shelter for miners under the mine when the mine collapses, thereby reducing casualties when mining accidents occur.

[0009] Preferably, the auxiliary component further comprises telescopic rods, one end of the four telescopic rods is fixedly connected to the top of the shell, and the other end of the four telescopic rods is fixedly connected to the top plate, and the top plate is arched.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First: In the present invention, several support devices can be prepared, and each support device can accommodate several people. Different numbers of support devices can be prepared according to the depth of the mine and the number of miners. If the mine is shallow, one support device can be fixed near the mine entrance, and then the remaining support devices can be connected in sequence until they reach the miner's working position below the mine. If the mine is deep, one support device can be fixed at a position close to the miner's work location below the mine, and then the remaining support devices can be connected in sequence until the support device extends to the miner's working position.

[0021] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides an anti-collapse mining support device through improvement. The technical solution of the utility model is:

[0023] like Figure 1-Figure 4 As shown, a support device for preventing collapse in mines comprises an outer shell 1, a hydraulic press 2 is fixedly connected to the interior of the outer shell 1, a top plate 3 is provided on the top of the outer shell 1, the output shaft of the hydraulic press 2 passes through the outer shell 1, and the output shaft of the hydraulic press 2 is fixedly connected to the top plate 3, a connecting component 5 is provided on the outer shell 1, the connecting component 5 comprises a fixed frame 51 and a movable frame 54, the fixed frame 51 and the movable frame 54 are respectively provided at two ends of the outer shell 1, and the edges of the fixed frame 51 and the movable frame 54 are both beveled edges, an auxiliary component 4 is provided on the outer shell 1, the edges of the fixed frame 51 and the movable frame 54 are beveled edges, which ensure that the fixed frame 51 and the movable frame 54 can be connected end to end, so that multiple support devices can be spliced ​​together in sequence.

[0024] Furthermore, the connecting assembly 5 also includes a rubber tube 53, which is fixedly connected to one end of the outer shell 1, the fixed frame 51 is fixedly connected to the other end of the outer shell 1, and the movable frame 54 is fixedly connected to the rubber tube 53. The rubber tube 53 is a retractable cylindrical rubber. When the movable frame 54 is connected to it, it can move within a certain range and maintain the seal between the movable frame 54 and the outer shell 1 during the movement. The rubber tube 53 is made of harder rubber and is not easily damaged by collapsed soil and rocks.

[0025] Furthermore, the connecting component 5 also includes a first screw hole 52 and a second screw hole 55. The four first screw holes 52 are respectively opened on both sides of the fixed frame 51, and the four second screw holes 55 are respectively opened on both sides of the movable frame 54. When the fixed frame 51 and the movable frame 54 are engaged together, the bolts can be installed into the first screw holes 52 and the second screw holes 55, so as to fix the fixed frame 51 and the movable frame 54 together, thereby realizing the connection between two adjacent support devices.

[0026] Furthermore, the auxiliary component 4 includes a shell 41 and a roller 42. The four shells 41 are arranged inside the outer shell 1. The four shells 41 are hollow structures. The inside of the four shells 41 is rotatably connected to the roller 42. The function of the roller 42 is to facilitate the movement of the device in the mine or to move using the underground rails.

[0027] Furthermore, the auxiliary component 4 also includes telescopic rods 43, one end of the four telescopic rods 43 is fixedly connected to the top of the shell 1, and the other end of the four telescopic rods 43 is fixedly connected to the top plate 3. The top plate 3 is arched, and the arched top plate 3 has good load-bearing capacity and can support the top wall of the mine. The telescopic rods 43 are used to limit the top plate 3 to only move up and down, so that the top plate 3 is not easily displaced when subjected to horizontal force.

[0028] The specific working method is: first prepare several support devices, each support device can accommodate several people. Different numbers of support devices can be prepared according to the depth of the mine and the number of miners. If the mine is shallow, a support device can be fixed near the mine entrance, and then the remaining support devices are connected in sequence until they reach the miner's working position below the mine. If the mine is deep, a support device can be fixed at a position close to the miner's work location below the mine, and then the remaining support devices are connected in sequence until the support device extends to the miner's working position.

[0029] When connecting the support devices, it is only necessary to send the support devices into the mine one by one. There are rollers 42 under the support devices, which can be easily moved or moved using the mine track. When the two support devices are in a front and back position, the mobile frame 54 on one of the support devices can be stretched. During the stretching process, the rubber tube 53 will extend until the mobile frame 54 is connected to the fixed frame 51 on the other support device. The fixed frame 51 can be inserted into the interior of the mobile frame 54 until the first screw hole 52 and the second screw hole 55 coincide with each other. At this time, the fixed frame 51 and the mobile frame 54 can be connected together using bolts. Since the rubber tube 53 is made of rubber, the mobile frame 54 can be slightly offset in addition to moving in a straight line. Therefore, when the mine road is not straight and the two adjacent support devices cannot be connected in a straight line, the mobile frame 54 can be slightly bent and moved to connect with the fixed frame 51.

[0030] After repeating the above operations and docking and installing several support devices, the hydraulic press 2 in each support device can be started in turn. After the hydraulic press 2 is started, the top plate 3 can be pushed upward until the top plate 3 is against the top wall of the mine, thereby supporting the mine. As long as there are several support devices near the place where the miners work, when the mine collapses, the miners can quickly enter the support device. The support device can provide shelter for the miners, and when several support devices are spliced ​​together, even if the collapsed soil and rocks enter the device, they can only enter a small distance. After that, the soil and rocks will not be able to penetrate into the support device due to resistance. Therefore, the support device can provide shelter for the miners until rescue arrives, and food, oxygen cylinders and other resources can also be prepared in advance in the device for backup.
