In this embodiment, by providing the strip block 101 on the mounting plate 1 and providing the strip slide groove 301 on the pressing plate 3, not only the detachable installation of the pressing plate 3 on the mounting plate 1 is realized through the design of the strip block 101 and the strip slide groove 301, but also the pressing plate 3 can be vertically moved on the mounting plate 1 through the strip slide groove 301 in cooperation with the strip block 101.

[0057] As a preferred embodiment, one end of the strip slide groove 301 is connected to the top of the pressing plate 3 to facilitate the pressing plate 3 to be installed on the mounting plate 1 through the cooperation of the strip slide groove 301 and the strip block 101 .

[0058] As another preferred embodiment, the pressing plate 3 includes a diamond block, and the strip slide groove 301 is opened on the diagonal line of the diamond block. In this embodiment, the pressing plate 3 is preferably a diamond block, so that when the two adjustment members move to contact the two sides of the pressing plate 3 respectively, the forces exerted by the adjustment members on the two sides of the diamond block are consistent, thereby avoiding the problem of different service lives of the two adjustment members due to different applied forces.

[0059] Furthermore, the pressing plate 3 further includes a pressing column 302, which is arranged at the bottom of the rhombus block and is used to contact and connect with the circular groove on the column cylinder bottom 4. In this embodiment, by arranging the pressing column 302 at the bottom of the rhombus block, the circular groove on the column cylinder bottom 4 can be more closely contacted with the pressing column 302, so that the column cylinder bottom 4 can be stably fixed on the column socket 2 by the pressing plate 3, and the interference of the strip surface at the bottom of the pressing plate 3 with the rotating circular groove is avoided.

[0060] Furthermore, the adjustment member is an adjustment block 5 with a bevel, and the bevels of the two adjustment blocks 5 are both arranged close to the rhombus block, and the angle between the bevels of the two adjustment blocks 5 is the same as the angle of the top angle of the rhombus block.

[0061] The adjustment block 5 is horizontally slidably connected to the mounting plate 1 through a second sliding assembly, the second sliding assembly includes a slideway 102 and a slider 501, the slideway 102 is arranged on the top of the mounting plate 1, the slider 501 is arranged on the adjustment block 5 and can be inserted into the slideway 102, and the slider 501 can slide in the slideway 102. In this embodiment, the slider 501 is arranged on the adjustment block 5 and can be inserted into the slideway 102, so that the adjustment block 5 can slide along the length direction of the slideway 102, and the detachable connection between the adjustment block 5 and the mounting plate 1 is also achieved.

[0062] Preferably, the fixing assembly includes a first connection block 103, a threaded hole 502 and a bolt 6. The first connection block 103 is arranged on both sides of the mounting plate 1. The first connection hole is arranged on the first connection block 103. The threaded hole 502 is arranged on the side of the adjustment block 5 away from the hypotenuse. The bolt 6 is used to connect the first connection hole and the threaded hole 502. The bolt 6 can adjust the distance between the adjustment block 5 and the first connection block 103 by the number of rotations on the threaded hole 502. In this embodiment, after the bottom of the pressing plate 3 moves into the circular groove on the column cylinder bottom 4, the two adjustment blocks 5 are respectively moved to contact with the two sides of the pressing plate 3, and then the adjustment blocks 5 are fixed on the mounting plate 1 by adjusting the number of rotations of the bolt 6 on the threaded hole, so that the pressing plate 3 can fix the column cylinder bottom 4 on the column socket 2 under the action of the adjustment block 5.

[0063] As another preferred embodiment, the fixing assembly includes a second connection block, a third connection hole and a lead screw. The second connection block is provided on both sides of the mounting plate 1 and is provided with a second connection hole. The third connection hole is provided on the side of the adjustment block 5 away from the hypotenuse. The lead screw is used to connect the second connection hole and the third connection hole.

[0064] As a preferred embodiment, an angle measuring component is provided on the mounting plate 1, and the angle measuring component is used to detect the placement angle of the top surface of the column cylinder bottom 4 on the column socket 2. In this embodiment, since the column as a whole needs to provide a large axial force output, there will also be a certain angle deviation. Therefore, by providing the angle measuring component on the mounting plate 1, the placement angle of the top surface of the column cylinder bottom 4 on the column socket 2 can be easily adjusted.

[0065] The method for using the hydraulic support column fixing device provided by the present invention is as follows:

[0066] After the pressure column 302 of the pressure plate 3 on the mounting plate 1 is inserted into the circular groove of the column cylinder bottom 4, the column cylinder bottom 4 is pressed tightly into the spherical groove of the column socket 2. The pressure plate 3 is adjusted up and down by moving left and right through two adjustment blocks 5, wherein the slider 501 on the adjustment block 5 is inserted into the slideway 102 on the mounting plate 1, so that the adjustment block 5 can slide along the slideway 102, and then the adjustment block 5 is fixed at the position in contact with both sides of the pressure plate 3 through the fixing assembly, so that the pressure plate 3 fixes the column cylinder bottom 4 on the column socket 2 under the action of the two adjustment parts.
