Description

Technical Field

[0001] The present application relates to the field of mining safety technology, and specifically to a protective plate for mining. Background Art

[0002] In mining operations, there are often various potential safety hazards in the working area, such as falling rocks, flying debris, and sudden collapse of mine walls. These dangerous factors may threaten the life safety of miners, so protective plates are needed. The main function of protective plates is to provide a solid barrier to block these potential hazards. By installing protective plates, the risk of injury to miners caused by falling rocks and debris can be effectively reduced, and the damage caused by mine wall collapse can also be reduced. Therefore, in mining operations, it is very important to use and install protective plates correctly. It can not only protect the safety of miners, but also improve the efficiency and quality of mining operations, ensuring that mining work can proceed smoothly. Existing protective plates can usually only block and protect one direction in a mine cave, and the environment in the mine cave is relatively narrow. When multiple directions need to be protected, multiple protective plates may block each other, resulting in inability to deploy, affecting the passage and safety of miners. Utility Model Content

[0003] The purpose of the present application is to provide a protective plate for mining, which solves the problem that the existing protective plates proposed in the background technology can usually only provide shielding and protection in one direction within a mine, and the environment within the mine is relatively narrow. When protection in multiple directions is required, multiple protective plates may block each other, resulting in inability to deploy, affecting the passage and safety of miners.

[0004] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a protective plate for mining, comprising a protective plate body, a buffer plate, a slider, a telescopic rod and an arc plate, the edges of the two protective plate bodies being detachably connected by hinges, a top slide groove being provided at the top of the protective plate body, a bottom plate being laterally slidably connected to the inner side of the top slide groove, a plurality of shock absorbers being evenly fixedly installed at the top of the bottom plate, bottom slide grooves being provided at both side edges of the bottom of the protective plate body, a slider being laterally slidably connected to the bottom slide groove, two parallel arc plates being fixedly installed at the bottom of the slider, a support shaft being movably installed between the side walls of the arc plates, a rotating block being fixedly welded to the surface of the support shaft.

[0005] The two protective plate bodies can be folded up to reduce space occupation, facilitate transportation, and improve the convenience of using the protective plate. At the same time, the top slide, bottom plate, shock absorber and buffer plate can increase the protection effect and facilitate replacement. The buffer plate can cooperate with the shock absorber below to buffer the external impact force, thereby increasing the protection effect. The buffer plate and the bottom plate can slide out of the top slide for replacement, thereby improving the practicality of the device.

[0006] As an optional solution of the technical solution of the present application, the bottom of the rotating block is fixedly connected to both ends of the surface of the telescopic rod.

[0007] As an optional solution of the technical solution of the present application, a plurality of threaded holes are evenly opened on the surface of the telescopic rod, and the inner sides of the threaded holes are threadedly connected with No. 3 fixing bolts.

[0008] As an optional solution of the technical solution of the present application, the bottom thread of the slider is connected with a No. 2 fixing bolt, and the top end of the No. 2 fixing bolt passes through the slider and is threadedly connected to the main body of the protective plate above.

[0009] As an optional solution of the technical solution of the present application, a No. 1 fixing bolt is threadedly connected at the four corners of the top end of the base plate, and the bottom of the No. 1 fixing bolt passes through the base plate and is threadedly connected to the protective plate body below.

[0010] As an optional solution of the technical solution of the present application, the top of the shock absorber is fixedly connected to the bottom of the buffer plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can change the angle of the protective plate body through the telescopic rod, rotating block, support shaft and arc plate. By adjusting the length of the telescopic rod and fixing it with No. 3 fixing bolts, the rotating blocks at both ends of the telescopic rod will be moved together.

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0020] like Figure 1 As shown, a protective plate for mining includes a protective plate body 1, a buffer plate 3, a slider 6, a telescopic rod 11 and an arc plate 8. The edges of the two protective plate bodies 1 are detachably connected by a hinge 2. A top slide groove 101 is provided at the top of the protective plate body 1, and the inner side of the top slide groove 101 is laterally slidably connected to a bottom plate 301.

[0021] like Figure 2 As shown, bottom slide grooves 5 are provided on both side edges of the bottom of the protective plate body, and a slider 6 is connected to the bottom of the slider 6 for transverse sliding. Two parallel arc plates 8 are fixedly installed on the bottom of the slider 6, and a support shaft 9 is movably installed between the side walls of the arc plates 8. A rotating block 10 is fixedly welded on the surface of the support shaft 9, and the bottom of the rotating block 10 is fixedly connected to the two ends of the surface of the telescopic rod 11. A number of threaded holes 12 are evenly provided on the surface of the telescopic rod 11, and the inner side of the threaded hole 12 is threadedly connected with a No. 3 fixing bolt 13. The telescopic rod 11 can adjust the length, thereby changing the angle of the protective plate body 1.

[0022] like Figure 2 and Figure 3 As shown, the bottom of the slider 6 is threadedly connected with a No. 2 fixing bolt 7, and the top of the No. 2 fixing bolt 7 passes through the slider 6 and is threadedly connected to the protective plate body 1 above.

[0023] like Figure 1 and Figure 3 As shown, the four corners of the top of the bottom plate 301 are threadedly connected with No. 1 fixing bolts 302, and the bottom of the No. 1 fixing bolts 302 penetrates the bottom plate 301 and is threadedly connected with the protective plate body 1 below.

[0024] like Figure 3 As shown, a plurality of shock absorbers 4 are evenly and fixedly installed on the top of the bottom plate 301, and the top of the shock absorber 4 is fixedly connected to the bottom of the buffer plate 3. The buffer plate 3 and the shock absorber 4 can buffer the external impact force, thereby increasing the protective effect.

[0025] In actual use, the angle of the protective plate body 1 can be changed through the telescopic rod 11, the rotating block 10, the support shaft 9 and the curved plate 8. By adjusting the length of the telescopic rod 11 and fixing it with the No. 3 fixing bolt 13, the rotating blocks 10 at both ends of the telescopic rod 11 will be moved together. At this time, the support shaft 9 and the curved plate 8 will also move with it, so that the two protective plate bodies 1 are lifted up to form an angle, so that they can better fit the inner wall of the mine cave, thereby improving the protection effect. In addition, the bottom slide groove 5, the slider 6 and the No. 2 fixing bolt 7 can facilitate the storage of the protective plate body 1. Unscrew the No. 2 fixing bolt By pulling out the bolt 7, the slider 6 can be slid out of the bottom slide groove 5, so that the telescopic rod 11 and the upper protective plate body 1 are separated. At this time, the two protective plate bodies 1 can be folded up, which reduces the space occupied, facilitates transportation, and improves the convenience of using the protective plate. At the same time, through the top slide groove 101, the bottom plate 301, the shock absorber 4 and the buffer plate 3, the protection effect can be increased and the replacement is convenient. The buffer plate 3 cooperates with the shock absorber 4 below to buffer the external impact force, thereby increasing the protection effect, and the buffer plate 3 and the bottom plate 301 can slide out from the top slide groove 101 for replacement, which improves the practicability of the device.
