When the support assembly 2 needs to be removed, the support assembly 2 can be removed by simply pulling the support assembly 2 to separate the second protrusion 41 from the second groove 51.

[0182] If the supporting surface that the device needs to support is larger, more support components 2 need to be set up under the working condition of one base 1, and a 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 component 2 is inserted into the second groove 51 on the first sliding member 5 through the second protrusion 41, so that the support component 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.

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.

[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, it is also necessary to adjust the support position of the underground mining advance support hydraulic support 100 accordingly to better adapt to the new mine pressure distribution condition.

[0186] Or when the working face advances and the mining impacts: 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 of the embodiment of the present invention are:

[0189] (1) After the base 1 of the present invention is pre-laid inside the mine, the inner wall of the mine is supported by the support assembly 2. 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, thereby reducing the difficulty of adjusting the device position and improving 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 moving direction of the guide wheel 92 is limited by the bottom groove 12, 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-mentioned beneficial effects, when the adjusting mounting plate 3 is moved on the base 1, the first protrusion 32 is inserted into the first groove 31 on one 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, so that the position of the mounting plate 3 and the support assembly 2 is easy to adjust, 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, only one of the damaged first supporting member 21 and the second supporting member 22 needs to be pulled and removed for replacement. This allows the device to work normally without overall disassembly and maintenance, thereby improving the working efficiency of the device.
