[0025] For further information, see Figure 2 The support column foot 1 includes a support bottom column 101 , a support top column 102 slidably disposed in the support bottom column 101 , and the adjustment rod 3 is disposed on the support top column 102 .

[0026] Preferably, four groups of support column feet 1 and sleeve rods 2 are respectively provided, and each group of support column feet 1 is provided with two groups of adjustment rods 3.

[0027] Preferably, a supporting bottom plate 7 is provided at one end of the supporting bottom column 101 away from the supporting top column 102 .

[0028] Preferably, a sliding cavity is provided in the supporting top column 102, and the supporting bottom column 101 is slidably located in the sliding cavity.

[0029] For further information, see Figure 1 、 2The first reinforcement member 4 includes a support plate 8 fixedly arranged on the support bottom column 101, a slide plate 9 fixedly arranged on the support top column 102, and a first reinforcement column 10 arranged on the support plate 8; the support plate 8 and the slide plate 9 are spaced apart, and one end of the first reinforcement column 10 slides through the slide plate 9; the first locking member 6 moves toward the slide plate 9 under the action of external force and clamps the slide plate 9, so that the distance between the support plate 8 and the slide plate 9 is fixed, thereby fixing the height of the support column foot 1.

[0030] Preferably, a through hole 11 is provided on the slide plate 9 , and the first reinforcement column 10 is a stud, and one end of the first reinforcement column 10 away from the support plate 8 passes through the through hole 11 .

[0031] Preferably, the first locking member 6 is a nut, and two sets of nuts are provided on each first reinforcement column 10. The two sets of nuts are respectively located on the upper and lower sides of the slide 9. The nuts are threadedly connected to the first reinforcement column 10, so that the height of the entire device can be fine-tuned.

[0032] In the above setting, the height of the entire support device can be adjusted by adjusting the height of the support column foot 1. During the adjustment process, the two sets of nuts on both sides of the slide 9 are loosened, and the position between the support bottom column 101 and the support top column 102 is adjusted to adjust the height of the support column foot 1. After the adjustment is completed, the nuts on both sides of the slide 9 are rotated, and the slide 9 is clamped by tightening the two sets of nuts, thereby connecting the first reinforcement column 10 to the slide 9. At this time, the position between the support bottom column 101 and the support top column 102 is fixed. The first reinforcement column 10 is located at the connection position of the support bottom column 101 and the support top column 102, which can strengthen the connection strength between the two.

[0033] For further information, see Figure 3 The second reinforcement member 5 includes a positioning block 12 connected to the middle part of the sleeve rod 2, a sliding block 13 fixed on the adjusting rod 3, and a second reinforcement column 14 arranged on the positioning block 12.

When adjusting the width or length of the entire support device, the four groups of support column feet 1 are grouped in twos horizontally or vertically, and the support column feet 1 are pulled toward or in the opposite direction. The adjusting rod 3 moves in the cavity of the sleeve rod 2, so that the spacing between the support column feet 1 can be adjusted. The second reinforcement rod moves in the sliding hole 15. The width or length adjustment range of the entire device is limited by the length of the second reinforcement rod. During the adjustment process, the end of the second reinforcement rod must always be kept out of the sliding hole 15. For tunnels of different widths or lengths, support devices of different sizes can be made, but the difference in the width or length range of the tunnel within the length range of the second reinforcement rod can be adapted by adjusting the size of this device.

[0037] In this embodiment, the height of the entire support device is adjusted by adjusting the height of the support column foot 1 and fixing the height of the support column foot 1 by the first locking member 6. When adjusting the width of the entire device, the two groups of support column feet 1 located on the left and right sides of the base point are divided into groups based on the center of the support assembly, and the support column feet 1 are moved away from or close to the base point. The adjusting rod 3 slides in the sleeve rod 2, and the second reinforcement rod moves in the sliding hole 15 to adjust the width of the entire support device. The principle of adjusting the length of the entire device is the same as that of adjusting the width. The difference is that the grouping of the support column feet 1 is different. By grouping the support column feet 1 in the front and rear directions of the base point and moving them, the length can be adjusted to adapt to different tunnels.

[0038] In one embodiment, see Figure 4 , and also includes a reinforcement component, which includes a reinforcement rod 18 and a support member 19 movably arranged on the reinforcement rod 18. The reinforcement rod 18 is detachably connected to the sleeve rod 2 or the adjustment rod 3. An adjustment member 20 is provided between the support member 19 and the reinforcement rod 18. The adjustment member 20 moves up or down under the action of external force, thereby adjusting the distance between the support member 19 and the reinforcement rod 18.

[0039] Preferably, the reinforcing rod 18 is a telescopic rod with adjustable length, and can also be customized according to the size of the supporting area.

[0040] For further information, see Figure 4 、 5 The adjusting rod 3 and the sleeve rod 2 are respectively provided with connecting grooves 21, and the two ends of the reinforcing rod 18 are located in the connecting grooves 21; the adjusting member 20 includes a clamping sleeve 2001 slidably located on the reinforcing rod 18, an adjusting sleeve 2002 arranged on the clamping sleeve 2001, and a second locking member 2003 is provided on the clamping sleeve 2001; a transfer rod 22 is provided in the adjusting sleeve 2002; the support member 19 includes a support plate 23 arranged on the transfer rod 22.

[0041] Preferably, the adjusting rod 3 , the sleeve rod 2 , and the sleeve rod 2 cavity are rods with an L-shaped cross-section, and the inner side surfaces of the adjusting rod 3 and the sleeve rod 2 are concave to form a connecting groove 21 .

[0042] Preferably, the clamping sleeve 2001 is a hollow rectangular body with openings at both ends. A screw hole is provided on the clamping sleeve 2001. The third locking member is connected to the screw hole by a stud. After moving the clamping sleeve 2001, the stud is rotated to abut against the reinforcing rod 18, thereby fixing the position of the clamping sleeve 2001 on the reinforcing rod 18.

[0043] Preferably, the adjustment sleeve 2002 is a hollow cylinder with one end open, and a thread is provided on the outer wall of the adjustment rod 3. The adjustment sleeve 2002 is connected to the adjustment rod 22 through the thread.

[0044] In this embodiment, after the tunnel is supported by the support column foot 1, the adjustment rod 3, and the sleeve rod 2, if the tunnel top is located directly above the support device or in an area with a cavity, the adjustment rod 3 and the sleeve rod 2 are difficult to provide support, the reinforcing rod 18 can be placed in the connecting groove 21, and the position of the clamping sleeve 2001 is moved to the area to be supported. The rotating adjustment rod 22 moves upward under the action of the thread, driving the support plate 23 to move upward to support the inner wall of the tunnel, thereby providing more comprehensive and stable support. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
