Description

Technical Field

[0001] The utility model relates to the technical field of support devices, and more specifically, to a mine roof support device. Background Art

[0002] Mine roof support is one of the key technologies in mine safety production. Traditional mine roof support systems usually include physical support structures, such as wooden or metal pillars, which provide the necessary support when the roof is unstable or under high pressure.

[0003] In mine roof support, the support device is usually fixed to the ground. If the ground becomes soft or sinks due to moisture, geological activities or long-term pressure, then even if the pressure of the roof remains unchanged, the effectiveness of the support device will be reduced due to the drop in the ground, which will lead to insufficient support force and increase the risk of roof collapse. Traditional support systems often lack real-time monitoring capabilities and cannot respond to changes in ground conditions in a timely manner, further exacerbating safety risks.

[0004] Therefore, a mine roof supporting device is proposed to address the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a mine roof support device, which can realize the real-time monitoring function of the roof support force by combining the adjustment component and the monitoring component. It can not only intuitively remind construction personnel to adjust the support structure in time, but also adapt to the ever-changing underground environment and enhance the safety of the mine roof.

[0007] 2. Technical solution

[0008] In order to solve the above problems, the present invention adopts the following technical solutions.

[0009] A mine roof support device includes a support plate, a hydraulic rod is fixedly connected to the top of the support plate, an abutment plate is fixedly connected to the output end of the hydraulic rod, a plurality of evenly distributed support rods are installed around the support plate, one end of the support rod is fixedly connected to a support foot, an adjustment component is installed at the bottom of the support plate, and a plurality of evenly distributed monitoring components are provided on the adjustment component.

[0010] Furthermore, the adjustment component includes an adjustment rod, the top end of the adjustment rod is fixedly connected to the support plate, the bottom end of the adjustment rod is fixedly connected to the base plate, a servo motor is installed in the support plate, the output end of the servo motor is fixedly connected to a reciprocating screw rod, and one end of the reciprocating screw rod is rotatably connected to the inner wall of the adjustment rod.

[0011] Furthermore, a screw sleeve is installed on the outer periphery of the reciprocating screw rod, one end of the screw sleeve is fixedly connected to a connecting block, and one end of the connecting block is fixedly connected to a movable plate.

[0012] Furthermore, a limiting groove is provided in the adjusting rod, one end of the screw sleeve is fixedly connected to the limiting block, and the limiting groove is slidably connected to the limiting block.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] This solution uses adjustment components to precisely adjust multiple monitoring components. When the ground softens and the bottom plate sinks, this change will cause the supporting force between the abutment plate and the top plate to decrease, thereby increasing the risk of top plate collapse. The monitoring tube in the monitoring component is equipped with a monitoring rod, the bottom of which is equipped with a rotating sphere and the periphery is equipped with a pressure plate. This structural design allows the monitoring rod to self-adjust under slight ground changes to maintain its vertical stability.

The real-time physical display not only intuitively reminds construction personnel to monitor changes in ground conditions and top plate support force, but also allows them to make necessary adjustments or enhance the support structure in a timely manner to cope with the ever-changing underground environment.

[0026] Example:

[0027] See also Figure 1-3 A mine roof support device includes a support plate 1, a hydraulic rod 11 is fixedly connected to the top of the support plate 1, an abutment plate 12 is fixedly connected to the output end of the hydraulic rod 11, a plurality of evenly distributed support rods 13 are installed around the support plate 1, one end of the support rod 13 is fixedly connected to a support foot 14, an adjustment component 2 is installed at the bottom end of the support plate 1, and a plurality of evenly distributed monitoring components 3 are arranged on the adjustment component 2.

[0028] Among them, the multiple monitoring components 3 are precisely adjusted through the adjustment component 2. When the ground softens and the bottom plate 15 sinks, this change will cause the supporting force between the abutment plate 12 and the top plate to decrease, thereby increasing the risk of top plate collapse. The monitoring tube 31 in the monitoring component 3 contains a monitoring rod 33, the bottom end of which is equipped with a rotating sphere, and the periphery is equipped with a pressure plate 32. This structural design allows the monitoring rod 33 to self-adjust under slight ground changes to maintain its vertical stability. When the ground softens and causes the bottom plate 15 to move downward, the contact of the pressure plate 32 with the ground will cause the monitoring rod 33 to push upward, causing it to protrude from the top of the monitoring tube 31, thereby intuitively showing the reduction in supporting force. The real-time physical display not only intuitively reminds construction personnel to monitor changes in ground conditions and top plate supporting force, but also allows them to make necessary adjustments or enhance the supporting structure in a timely manner to cope with the ever-changing underground environment.

[0029] The adjusting assembly 2 includes an adjusting rod 21, the top end of the adjusting rod 21 is fixedly connected to the support disk 1, the bottom end of the adjusting rod 21 is fixedly connected to the base plate 15, a servo motor is installed in the support disk 1, the output end of the servo motor is fixedly connected to a reciprocating screw rod 22, one end of the reciprocating screw rod 22 is rotatably connected to the inner wall of the adjusting rod 21, a screw sleeve 23 is installed on the outer periphery of the reciprocating screw rod 22, one end of the screw sleeve 23 is fixedly connected to a connecting block 24, one end of the connecting block 24 is fixedly connected to a movable plate 25, a limiting groove is provided in the adjusting rod 21, one end of the screw sleeve 23 is fixedly connected to the limiting block, and the limiting groove is slidably connected to the limiting block.

[0030] Among them, the adjustment component 2 drives the reciprocating screw 22 through a built-in servo motor. The output end of the servo motor is connected to the reciprocating screw 22, passes through the adjustment rod 21 and is rotatably connected to its inner wall. The screw sleeve 23 installed on the periphery of the reciprocating screw 22 moves up and down with the rotation of the screw. The movement of the screw sleeve 23 is converted into a vertical displacement of the movable plate 25 through a connecting block 24 fixedly connected to the screw sleeve 23 and a movable plate 25 on the connecting block.

[0031] By starting the adjustment component 2, the movable plate 25 can be driven to move synchronously, so that after the supporting action is completed, the contact between the multiple monitoring components 3 and the ground is adjusted, so that the monitoring components 3 can play their early warning function.

[0032] The monitoring assembly 3 includes a monitoring tube 31, one end of which is fixedly connected to the movable plate 25, a monitoring rod 33 is slidably connected inside the monitoring tube 31, an extrusion disk is installed around the monitoring rod 33, an extrusion spring is fixedly connected to the top of the extrusion disk, and the top of the extrusion spring is fixedly connected to the inner wall of the monitoring tube 31.

[0033] A rotating sphere is installed at the bottom end of the monitoring rod 33, and a pressing plate 32 is installed outside the rotating sphere.

[0034] Among them, the monitoring rod 33 can slide up and down inside the monitoring tube 31. The monitoring rod 33 is equipped with an extrusion disk on the periphery, and an extrusion spring is connected to the top of the extrusion disk. The other end of the extrusion spring is fixedly connected to the inner wall of the monitoring tube 31. When the movable plate 25 moves, it synchronously drives multiple monitoring components 3 to move downward. Under the action of the extrusion spring, by adjusting the operation of the component 2, the pressing disk 32 in the monitoring tube 31 is abutted against the ground, so that the monitoring rod 33 is level with the horizontal plane of the top of the monitoring tube 31, thereby exerting its subsequent detection effect.

[0035] When the bottom plate 15 moves downward due to the soft ground, the supporting force of the abutment plate 12 and the top plate will become smaller, which will cause certain safety hazards. The pressure plate 32 in the monitoring tube 31 contacts the ground, and the bottom end of the monitoring rod 33 is installed with a rotating sphere. The outer periphery of the sphere is equipped with a pressure plate 32. The rotating sphere allows the monitoring rod to be fine-tuned when receiving the pressure change of the top plate to maintain its vertical stability, so that the monitoring rod 33 is lifted up by the contact between the pressure plate 32 and the ground, so that the monitoring rod 33 is exposed from the initial adjustment state flush with the top of the monitoring tube 31, so that the bottom plate 15 moves due to the soft ground, indicating that the supporting force of the abutment plate 12 and the top plate has become smaller, thereby reminding the construction personnel to make adjustments.

[0036] Working principle:

[0037] Through the coordinated work of the adjustment component 2 and the monitoring component 3, the supporting force between the mine roof and the ground is monitored and adjusted in real time to cope with the softening of the ground and the sinking of the bottom plate 15. Specifically, the system includes a support plate 1, the top of which is fixedly connected to the abutment plate 12 by a hydraulic rod 11, which is used to directly support the top plate. A plurality of support rods 13 are installed around the support plate 1, and the bottom of each support rod 13 is fixedly connected to a support leg 14. These support legs help to stably place the entire device at the bottom of the mine. The adjustment component 2 is located at the bottom end of the support plate 1, and includes a reciprocating screw 22 driven by a servo motor. The screw passes through the adjustment rod 21 and is rotatably connected to its inner wall. A screw sleeve 23 is installed on the periphery of the reciprocating screw 22, and one end of the screw sleeve 23 is fixedly connected to a connecting block 24, and one end of the connecting block is fixedly connected to a movable plate 25. The servo motor drives the screw sleeve 23 to move up and down along the screw by rotating the reciprocating screw 22, thereby controlling the vertical position of the movable plate 25. The cam 33 is moved upwards by the contact of the pressing plate 32 with the ground, and protrudes from the top of the monitoring tube 31, intuitively showing the reduction in supporting force. This real-time physical display enables construction personnel to promptly understand changes in ground conditions and roof support force, and take corresponding measures to adjust or strengthen the supporting structure to ensure the safety and stability of the mine.
