Description

Technical Field

[0001] This utility model belongs to the field of coal mine mining support technology, and in particular relates to a coal mine mining support structure. Background Technology

[0002] Coal mining is the process by which humans extract coal resources in coal-rich areas. It is generally divided into underground coal mines and open-pit coal mines. In order to protect the safety of workers and prevent the mine tunnels from collapsing during the coal mining process, support structures are often built in the coal mine tunnels.

[0003] Existing coal mine support structures are not ideal in use. Falling rocks in the coal mine directly hit the top of the support, which will damage the overall support structure after long-term use and reduce the safety of the support. Moreover, the ground in coal mines is mostly not smooth, and some support structures installed in the coal mine will experience overall frame swaying, resulting in poor stability. There is no special equipment to fix them, and the applicable environment is relatively limited. Utility Model Content

[0004] The purpose of this utility model is to provide a coal mine mining support structure in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A coal mine mining support structure includes a support top cover and support plates fixed to both sides of the lower end of the support top cover. A protective component is provided on the top of the support top cover, and stabilizing components are provided at both ends of the inner side of the support plates. Rolling wheels are provided on both sides of the bottom of the support plates.

[0007] The protective assembly includes a protective cover, with multiple first springs evenly arranged on the top between the protective cover and the support top cover. Connecting plates are fixed to the top of both ends of the protective cover, and the connecting plates are connected to the support plate through a buffer component. The buffer component includes a placement groove opened on the top of the support plate, the placement groove communicating with the outer wall of the support plate. The connecting plate is located directly above the placement groove. The buffer component includes multiple second springs evenly fixed to the bottom of the connecting plate. The lower end of the second spring is fixedly connected to the bottom wall of the placement groove. A limit rod is vertically fixed inside the second spring, and the limit rod cooperates with a limit hole opened on the bottom wall of the placement groove.

[0008] Preferably, the depth of the limiting hole is greater than the length of the limiting rod.

[0009] Preferably, the stabilizing component includes a groove formed inside the support plate, a control box is fixed to one side of the bottom wall of the groove, a hydraulic telescopic rod is fixed to the top wall of the groove on one side of the control box, the telescopic end of the bottom of the hydraulic telescopic rod penetrates the bottom wall of the groove, and a support plate is fixed to the bottom of the telescopic rod.

[0010] Preferably, the support plate is located on one side of the rolling wheel and does not contact the rolling wheel.

[0011] The beneficial effects are as follows: by setting up protective components, the protective effect of the support structure can be improved. The protective cover can buffer falling rocks, prevent rocks from directly damaging the support structure, extend the service life of the support structure, and improve the safety and protective effect of the support structure. By setting up stabilizing components, workers can fix the four corners of the support structure, preventing the overall support structure from becoming unstable due to potholes in the road surface. This can improve the stability and applicability of the support structure. Attached Figure Description

[0018] The technical solution of this utility model will be further explained below with reference to the accompanying drawings:

[0019] like Figures 1-3As shown, a coal mine mining support structure includes a support top cover 2 and support plates 1 fixed on both sides of the lower end of the support top cover 2. A protective component is provided on the top of the support top cover 2. Stabilizing components are provided at both ends of the inner side of each support plate 1. Rolling wheels 8 are fixedly installed on both sides of the bottom of each support plate 1.

[0020] The protective assembly includes a protective cover 3, which is configured with an arc shape. Multiple first springs 4 are evenly fixed between the protective cover 3 and the support top cover 2. The two ends of the first springs 4 are fixedly connected to the protective cover 3 and the support top cover 2 respectively. The first springs 4 are located on the top of the support top cover 2. Connecting plates 31 are fixed to the top of both ends of the protective cover 3 respectively. The connecting plates 31 are connected to the support plate 1 through a buffer component.

[0021] The buffer component includes a placement groove 12 formed on the top of the support plate 1. The placement groove 12 communicates with the outer wall of the support plate 1 and does not penetrate the inner wall of the support plate 1. The connecting plate 31 is located directly above the placement groove 12. The buffer component includes a plurality of second springs 5 ​​evenly fixed to the bottom of the connecting plate 31. The lower end of the second spring 5 is fixedly connected to the bottom wall of the placement groove 12. A limit rod 32 is vertically fixed inside the second spring 5. A plurality of limit holes 13 are evenly formed on the bottom wall of the placement groove 12. Each limit rod 32 is slidably connected to the corresponding limit hole 13. The depth of the limit hole 13 is greater than the length of the limit rod 32. When the spring is in normal extension, the lower part of the limit rod 32 is located inside the limit hole 13, thus preventing the limit rod 32 from sliding out of the limit hole 13.

[0022] The stabilizing component includes a groove 11 formed inside the support plate 1. A control box 7 is fixed to one side of the bottom wall of the groove 11. A hydraulic telescopic rod 6 is fixed to the top wall of the groove 11 on one side of the control box 7. The telescopic end of the bottom of the hydraulic telescopic rod 6 passes through the bottom wall of the groove 11. A support plate 61 is fixed to the bottom of the telescopic rod. The control box 7 is electrically connected to the hydraulic telescopic rod 6. The support plate 61 is located on one side of the roller 8 and does not contact the roller 8.

[0023] Working principle: During use, workers adjust the stability of the support structure according to the actual conditions of the road surface inside the coal mine. When the rolling wheel 8 at the bottom of the support structure is not in contact with the ground, the workers activate the hydraulic telescopic rod 6 through the control box 7. The hydraulic telescopic rod 6 drives the support plate 61 to extend. After the telescopic plate contacts the ground, the hydraulic telescopic rod 6 stops operating. At this time, the overall support structure will not shake, thus improving stability. The protective cover 3 can protect the support top cover 2, preventing rocks from falling directly onto the support structure, thus protecting the support structure and enhancing its protective effect.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
