Description

Technical Field

[0001] This utility model relates to the field of mining support technology, and more specifically, to a mining support device. Background Technology

[0002] Mining support devices are important equipment used in underground mining operations to ensure miner safety and prevent rock collapse. They are widely used in the support of longwall mining faces such as coal mines. They can provide strong support force, directly supporting the overlying rock strata through physical barriers, reducing rock movement and potential collapse risks, and effectively distributing the weight of the overlying rock strata to a wider area, thereby reducing local stress concentration, creating a relatively safe working environment for miners, and reducing the risk of accidental collapse.

[0003] Chinese Patent Publication No. CN222010244U discloses a mining support device, which includes a top plate and two pillars fixedly connected to the top plate. The two pillars are located on both sides below the top plate. A lifting plate is provided above the top plate. A lifting screw is rotatably connected to the top plate in the vertical direction. The lifting screw passes through the lifting plate and is threadedly connected to the lifting plate. A guide rod is provided on the top plate in the vertical direction. The guide rod passes through the lifting plate and is slidably connected to the lifting plate. A support plate body is provided on the lifting plate. The device is fixed by the pillars. By rotating the lifting screw, the lifting plate moves to adjust the height of the support plate body, so that the top of the support plate body abuts against the top of the mine inner wall, thereby improving the stability of the support and facilitating the adjustment of the height of the mining support device. The guide rod guides and limits the movement of the lifting plate, thereby improving the stability of the height adjustment process of the mining support device.

[0004] In practical use, existing non-removable support devices are often difficult to transport due to their large size, especially in narrow or obstructed areas. They may need to find alternative routes or even be unable to pass through at all. Therefore, a mining support device is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a mining support device. It consists of two arc-shaped protective plates spliced ​​together to form an arc-shaped structure that fits tightly against the top or sidewall of the tunnel, providing direct physical protection. T-slots are provided on the protective plates, and cross frames are installed below the protective plates via T-blocks. The upper end of the cross frames is arc-shaped to provide additional support at the joints of the protective plates. After the components are spliced, they can be locked with a bolt and a threaded sleeve, reducing the complexity of installation. Moreover, all the components of this device are individual parts that can be flexibly disassembled and installed. Because the individual parts are small in size, operators can more easily carry them for transportation and temporary storage in narrow mine tunnels, avoiding the need to find detours or even pass through areas that are particularly narrow or have obstacles.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A mining support device includes a protective plate with a T-slot in its inner cavity. A T-block is slidably connected to the inner cavity of the T-slot. A cross frame is fixedly connected to the lower surface of the T-block. Two limiting plates are symmetrically fixedly connected to both ends of the cross frame. Multiple support rods are evenly installed on the lower surface of the protective plate. A sleeve rod is fitted onto the outer surface of each support rod. Multiple adjustment holes are evenly opened on the outer surface of each support rod. A positioning bolt is inserted into the inner cavity of each adjustment hole. An installation plate is fixedly connected to the outer surface of the sleeve rod. A screw is threadedly connected to the inner cavity of the installation plate. A movable plate is rotatably connected to the lower end of the screw. A brake caster is installed on the lower surface of the movable plate.

[0010] Furthermore, there are two protective plates, which are spliced ​​together to form an arc shape, with the lower end of the protective plate located between two limiting plates.

[0011] Furthermore, the protective plate, the limiting plate, and the support rod are fixedly connected by bolts and threaded sleeves.

[0012] Furthermore, the inner cavity of the sleeve is threaded, the outer surface of the positioning bolt is threaded to the inner cavity of the sleeve, and a base plate is fixedly connected to the lower end of the sleeve, with four mounting holes evenly provided on the base plate.

[0013] Furthermore, a limiting rod is fixedly connected between the mounting plate and the base plate, and the limiting rod is inserted into the inner cavity of the moving plate.

[0014] Furthermore, the upper end of the cross frame is arc-shaped and abuts against the lower surface of the protective plate, and two T-shaped blocks are symmetrically arranged on the upper surface of the cross frame.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution uses two arc-shaped protective plates spliced ​​together to form an arc-shaped structure that fits tightly against the top or side wall of the tunnel, providing direct physical protection. T-slots are provided on the protective plates, and cross frames are installed below the protective plates by T-blocks. The upper end of the cross frames is arc-shaped to provide additional support at the joint of the protective plates. After the parts are spliced, they can be locked with a bolt and a nut, reducing the complexity of installation. All parts of this device are individual components that can be flexibly disassembled and installed. Since the individual parts are small, operators can carry them more conveniently for transportation and temporary storage in narrow mine tunnels, avoiding situations where it is necessary to find a detour route or even be unable to pass through when encountering particularly narrow or obstructed places.

[0018] (2) This solution uses nails to nail the base plate to the ground through the mounting holes to keep it stable. When it is necessary to move the protective plate in the mine, the nails used for fixing are pulled out, and then the screw is turned to drive the moving plate to move downward with the help of the limit rod. This causes the brake caster to move downward and contact the ground, so that the base plate leaves the ground. At this time, the operator can directly push the device to move it flexibly through the brake caster, which facilitates the movement of the entire device in the mine and can quickly fix the position when needed. The system significantly improves the mobility of the entire device in the mine, reduces the consumption of manpower and material resources, and improves work efficiency. Attached Figure Description

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a mining support device, including a protective plate 1. The inner cavity of the protective plate 1 is provided with a T-shaped groove 2. A T-shaped block 3 is slidably connected to the inner cavity of the T-shaped groove 2. A cross frame 4 is fixedly connected to the lower surface of the T-shaped block 3. Two limiting plates 5 are symmetrically fixedly connected to both ends of the cross frame 4. A plurality of support rods 6 are evenly installed on the lower surface of the protective plate 1. A sleeve rod 9 is sleeved on the outer surface of the support rod 6. A plurality of adjustment holes 10 are evenly opened on the outer surface of the support rod 6. A positioning bolt 11 is inserted into the inner cavity of the adjustment hole 10.

[0030] Specifically, there are two protective plates 1, which are spliced ​​together to form an arc shape. The lower end of the protective plate 1 is located between two limiting plates. The protective plate 1, the limiting plate 5 and the support rod 6 are fixedly connected by bolts 7 and threaded sleeves 8. The upper end of the cross frame 4 is arc-shaped and abuts against the lower surface of the protective plate 1. There are two T-shaped blocks 3 symmetrically arranged on the upper surface of the cross frame 4.

[0031] Furthermore, two arc-shaped protective plates 1 are spliced ​​together to form an arc-shaped structure, which can fit tightly against the top or sidewall of the tunnel, providing direct physical protection. T-slots 2 are provided on the protective plates 1, and T-blocks 3 are used to install the cross frame 4 below the protective plates 1. The cross frame 4 is adjusted to a suitable support position by sliding the T-blocks 3 within the T-slots 2. Two limiting plates 5 are fitted onto the lower end of the protective plates 1 for support connection. The cross-shaped structure of the cross frames 4 improves stability, and the arc-shaped upper end of the cross frame 4 provides additional support at the joints of the protective plates 1. It also provides a fixing point for the support rod 6. The protective plate 1, the limiting plate 5 and the support rod 6 are fixedly connected by bolts 7 and threaded sleeves 8. After the parts are assembled, they can be locked with a bolt and a threaded sleeve, which reduces the cumbersomeness of installation. Moreover, all the parts of the device are individual components that can be flexibly disassembled and installed. Since the individual parts are small in size, the operators can carry them more conveniently for transportation and temporary storage in narrow mine tunnels, avoiding the need to find detour routes or sometimes being unable to pass through when encountering particularly narrow or obstacle-filled places.

[0032] The outer surface of the support rod 6 is fitted with a sleeve rod 9, which is inserted into the inner cavity of the adjustment hole 10 by rotating the positioning bolt 11, thereby locking the support rod 6 and the sleeve rod 9 at a specific height to adapt to the support and protection needs of different heights and to provide stable vertical support. The lower end of the sleeve rod 9 contacts the ground through the base plate 12, and the base plate 12 is nailed to the ground through the mounting hole by nails to keep it stable.

[0033] The protective plate 1 is made of high-strength steel and may have undergone special treatment to increase corrosion resistance. It directly bears the pressure from above and protects miners from falling rocks. The cross frame 4 is made of high-strength alloy steel to ensure sufficient load-bearing capacity while maintaining a lightweight design.

[0034] Example 2

[0035] Reference Figure 1 and Figure 2This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The outer surface of the sleeve rod 9 is fixedly connected to the mounting plate 13. The inner cavity of the mounting plate 13 is threadedly connected to the screw 15. The lower end of the screw 15 is rotatably connected to the movable plate 16. The lower surface of the movable plate 16 is equipped with a brake universal wheel 17.

[0036] Specifically, a limiting rod 14 is fixedly connected between the mounting plate 13 and the base plate 12, and the limiting rod 14 is inserted into the inner cavity of the moving plate 16.

[0037] Furthermore, when it is necessary to move the protective plate 1 within the mine, the fixing nails are pulled out, and then the screw 15 is rotated to drive the moving plate 16 to move downward with the cooperation of the limit rod 14, which in turn drives the brake caster 17 to move downward and contact the ground, so that the bottom plate 12 leaves the ground.

[0038] Operators can directly push the device to move it flexibly via the brake casters 17, facilitating the movement of the entire device within the mine and quickly fixing it in place when needed. The wheels of the brake casters 17 are mostly made of wear-resistant materials such as polyurethane, while the bearings are required to have good wear resistance to ensure long-term use in harsh environments.

[0039] Working principle: During the use of the device, two arc-shaped protective plates 1 are spliced ​​together to form an arc-shaped structure, which can closely fit the top or side wall of the tunnel, providing direct physical protection. T-slots 2 are provided on the protective plates 1, and T-blocks 3 are used to install the cross frame 4 below the protective plates 1. The cross frame 4 is adjusted to a suitable support position by sliding the T-blocks 3 within the T-slots 2. The lower end of the cross frame 4 is supported by two limiting plates 5 fitted onto the lower end of the protective plates 1. The cross-shaped structure of the cross frames 4 improves stability, and the arc-shaped upper end of the cross frame 4 provides additional support at the joint of the protective plates 1, while also providing a fixing point for the support rod 6. The protective plates 1, limiting plates 5, and support rod 6 are fixedly connected by bolts 7 and threaded sleeves 8. A sleeve 9 is fitted onto the outer surface of the support rod 6. The support rod 6 and sleeve rod 9 are locked at a specific height by rotating the positioning bolt 11 and inserting it into the inner cavity of the adjustment hole 10, thus adapting to the support and protection needs of different heights and providing stable vertical support. The lower end of the sleeve rod 9 contacts the ground through the base plate 12, and the base plate 12 is nailed to the ground through the mounting hole with nails to keep it stable. When it is necessary to move the protective plate 1 in the mine, the nails used for fixing are pulled out, and then the screw 15 is rotated to drive the moving plate 16 to move downward with the cooperation of the limit rod 14, which drives the brake caster 17 to move downward and contact the ground, so that the base plate 12 leaves the ground. At this time, the operator can directly push the device to move flexibly through the brake caster 17, which facilitates the movement of the entire device in the mine and can quickly fix the position when needed.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
