The support assembly 2 includes a first support member 21 and a second support member 22. The first support member 21 and the second support member 22 are both provided on the base 1 and are relative to the base 1 along the width direction of the base 1 (as shown in the left and right directions). Figure 1 The first supporting member 21 and the second supporting member 22 are movable in the up-down direction, so that the first supporting member 21 and the second supporting member 22 support the tunnel. The supporting assembly 2 has a first working state and a second working state. In the first working state, at least one supporting assembly 2 moves on the base 1, and / or at least one of the first supporting member 21 and the second supporting member 22 moves on the base 1. In the second working state, at least two supporting assemblies 2 are connected, and / or the first supporting member 21 and the second supporting member 22 of at least one supporting assembly 2 are connected. Specifically, as Figure 1 and Figure 2As shown, a plurality of support assemblies 2 are sequentially arranged on the base 1 along the left-right direction, and the support assemblies 2 can be moved on the base 1 along the left-right direction. Each support assembly 2 includes a first support member 21 and a second support member 22. The first support member 21 and the second support member 22 are arranged along the front-back direction and can be moved along the front-back direction. The first support member 21 and the second support member 22 can be moved in the up-down direction so that the first support member 21 or the second support member 22 is against the top plate of the tunnel, thereby supporting the tunnel.

After the position of the support assembly 2 is adjusted, the support assembly 2 works to support the inner wall of the mine, thereby supporting the mine and making the mine more stable during construction. When the position of the support assembly 2 needs to be adjusted, the mounting plate 3 is pulled to drive the sliding seat 91 and the guide wheel 92 to move, and the second slide groove 11 and the bottom groove 12 cooperate to move the mounting plate 3 and the support assembly 2 relative to the base 1, thereby adjusting the position of the mounting plate 3 and the support assembly 2. After the position of the support assembly 2 is adjusted, the support assembly 2 works to support the inner wall of the mine, thereby supporting the mine, thereby completing the position adjustment of the support assembly 2. When the support assembly 2 needs to be removed, it only needs to pull the support assembly 2 to separate the second protrusion 41 from the second groove 51 to remove the support assembly 2.

[0182] If the device needs to support a larger supporting surface, more support assemblies 2 need to be set under the working condition of one base 1, and one base 1 is laid inside the mine. After the base 1 is laid, the first sliding member 5 is supported by the mounting plate 3, and the support assembly 2 is inserted into the second groove 51 on the first sliding member 5 through the second protrusion 41, so that the support assembly 2 is fixed on the first sliding member 5, and the moving direction of the sliding seat 91 is restricted by the second slide groove 11, and the moving direction of the guide wheel 92 is restricted by the bottom groove 12.

Through the cooperation of the second slide groove 11 and the bottom groove 12, the mounting plate 3 and the support assembly 2 are moved relative to the base 1, thereby adjusting the position of the mounting plate 3 and the support assembly 2. After the position of the support assembly 2 is adjusted, the support assembly 2 works to support the inner wall of the mine, thereby supporting the mine, making the mine more stable during construction. When the position of the support assembly 2 needs to be adjusted, the mounting plate 3 is pulled to drive the sliding seat 91 and the guide wheel 92 to move. Through the cooperation of the second slide groove 11 and the bottom groove 12, the mounting plate 3 and the support assembly 2 are moved relative to the base 1, thereby adjusting the position of the mounting plate 3 and the support assembly 2. After the position of the support assembly 2 is adjusted, the support assembly 2 works to support the inner wall of the mine, thereby supporting the mine, thereby completing the position adjustment of the support assembly 2. When the support assembly 2 needs to be removed, it is only necessary to pull the support assembly 2 to separate the second protrusion 41 from the second groove 51 to remove the support assembly 2.

[0183] Under the working condition of one base 1, the stroke of the second slide groove 11 on the base 1 is limited. Therefore, the number of connecting plates 6 connected to one base 1 is limited. In order to increase the adjustment number of the support assembly 2, the number of bases 1 needs to be adjusted. Therefore, the bases 1 required by the personnel are laid inside the mine. After the base 1 is laid, the first sliding member 5 is supported by the mounting plate 3, and the support assembly 2 is inserted into the second groove 51 on the first sliding member 5 through the second protrusion 41, so that the support assembly 2 is fixed on the first sliding member 5, and the moving direction of the sliding seat 91 is restricted by the second slide groove 11, and the moving direction of the guide wheel 92 is restricted by the bottom groove 12.

According to the above steps, the number of mounting plates 3 required by the personnel is connected, and the mounting plate 3 is pulled. When the support assembly 2 needs to be removed, the support assembly 2 can be removed by simply pulling the support assembly 2 so that the second protrusion 41 and the second groove 51 are separated.

[0184] To sum up, the underground mining advance support hydraulic support 100 of the embodiment of the present invention is used when the tunnel roof sinks significantly, the bottom plate bulges or the two sides move closer together, indicating that the pressure on the tunnel increases. At this time, the support position of the underground mining advance support hydraulic support 100 can be adjusted to better control the deformation of the tunnel and maintain the stability of the tunnel.

[0185] Or according to the mine pressure observation results, if the influence range of the advance support pressure is expanded or the stress peak position moves forward, the support position of the underground mining advance support hydraulic support 100 also needs to be adjusted accordingly to better adapt to the new mine pressure distribution condition.

[0186] Or when the working face advances and the mining impact: As the working face continues to advance, the mining impact range will gradually expand, and the underground mining advance support hydraulic support 100 needs to adjust the support position accordingly to ensure that the tunnel roof is always effectively supported.

[0187] Or during the advancement of the working face, if a complex geological structure area (such as faults, folds, etc.) is encountered, the mine pressure in these areas is often severe. At this time, it is also necessary to adjust the support position of the underground mining advance support hydraulic support 100 according to the specific situation.

[0188] The beneficial effects of the underground mining advance support hydraulic support 100 according to the embodiment of the present invention are:

[0189] (1) The present invention supports the inner wall of the mine through the support assembly 2 after the base 1 is pre-laid inside the mine. When the position of the support assembly 2 needs to be readjusted, the support assembly 2 is separated from the inner wall of the mine, and the mounting plate 3 is pulled. The moving direction of the second sliding member 9 is limited by the second slide groove 11, thereby adjusting the position of the support assembly 2. When the device needs to adjust the support position, the support position can be readjusted without removing the device, which reduces the difficulty of adjusting the device position and improves the adjustment efficiency of the device position.

[0190] (2) On the basis of the above beneficial effects, the present invention supports the guide wheel 92 through the second slide groove 11. When the bottom rod is pulled to move, the guide wheel 92 rolls, and the bottom groove 12 limits the moving direction of the guide wheel 92, so that the bottom rod moves more smoothly, thereby allowing the mounting plate 3 to drive the first sliding member 5 to move more smoothly, and the support assembly 2 to adjust its position more smoothly, further reducing the difficulty of adjusting the device position and improving the adjustment efficiency of the device position.

[0191] (3) On the basis of the above beneficial effects, when the adjusting mounting plate 3 moves on the base 1, the first protrusion 32 is inserted into the first groove 31 on the side of the adjacent mounting plate 3. When the present invention adjusts the position of the support assembly 2 by pulling the mounting plate 3, multiple mounting plates 3 can be moved synchronously or individually, making it easy to adjust the position of the mounting plate 3 and the support assembly 2, further reducing the difficulty of adjusting the device position and improving the adjustment efficiency of the device position.

[0192] (4) The present invention fixes the support assembly 2 on the mounting plate 3 by inserting the second protrusion 41 into the second groove 51 on the first sliding member 5. When one of the first supporting member 21 and the second supporting member 22 is damaged, it is only necessary to pull one of the damaged first supporting member 21 and the second supporting member 22, remove the damaged one of the first supporting member 21 and the second supporting member 22 and replace it, so that the device can work normally without the need for overall disassembly and maintenance, thereby improving the working efficiency of the device.
