[0027] As Figures 1-4 shown, the present application provides a support frame for drilling holes in coal mine development, including:

[0028] The first support mechanism 1 includes a support base 11 and a plurality of support legs 12, and the plurality of support legs 12 are hingedly arranged at the bottom of the support base 11;

[0029] The rotating mechanism 2 is rotatably arranged on the top of the support base 11;

[0030] The second support mechanism 3 includes a connecting mounting plate 31 and a rotating base 32, and the rotating base 32 is rotatably arranged on the rotating mechanism 2 to adjust the drilling angle of the drilling device 5 arranged on the mounting plate 31.

[0031] Specifically, the support frame includes a first support mechanism 1, a rotating mechanism 2 arranged on the first support mechanism 1, and a second support mechanism 3 arranged on the rotating mechanism 2. That is to say, the second support mechanism 3 is rotatably arranged on the first support mechanism 1 through the rotating mechanism 2. In this way, the first support mechanism 1 can rotate 360° around the vertical direction and can adapt to drilling at different positions. Among them, the first support mechanism 1 includes a support base 11 and a plurality of support legs 12, and the plurality of support legs 12 are connected at the bottom of the support base 11. That is to say, the plurality of support legs 12 can be expanded or retracted, and the height of the support base 11 can be adjusted, that is, the height of the drilling device 5 can be adjusted. The second support mechanism 3 includes a rotating base 32 and a mounting plate 31. The rotating base 32 rotates on the rotating mechanism 2, and the drilling device 5 is arranged on the mounting plate 31. That is to say, the rotating base 32 can rotate relative to the rotating mechanism 2 around the horizontal direction and can drive the drilling device 5 to perform angle adjustment along the horizontal direction. Through the rotating base 32 and the rotating mechanism 2, the drilling device 5 can be driven to be adjusted at multiple angles, which is convenient for drilling and avoids always moving the drilling, which is time-consuming and laborious.

[0032] In some embodiments, as Figures 1-2 shown, the plurality of support legs 12 include three, and the three support legs 12 are arranged at equal distances around the bottom of the support base 11.

[0033] Specifically, three support legs 12 are rotatably arranged around the bottom of the support base 11, and the three support legs 12 have stability. And the three support legs 12 are rotatably connected to the bottom of the support base 11, and the expansion amplitude of the three support legs 12 can be adjusted, so that the height adjustment of the support base can be realized. For example, three mounting positions are arranged at the bottom of the support base 11, and the ends of the three support legs 12 are rotatably installed in the mounting positions through rotating shafts.

[0034] In some embodiments, as Figures 1-2As shown, a guide rod 15 is provided at the middle position among the plurality of support legs 12 at the bottom of the support base 11. A moving member 14 is provided on the guide rod 15. A fixing ring 121 is provided on the support leg 12. The fixing ring 121 and the moving member 14 are connected by a connecting rod 13. Both ends of the connecting rod 13 are hinged to the fixing ring 121 and the moving member 14 respectively.

[0035] Specifically, when the support legs 12 are spread outwards, the fixing ring 121 on the support leg 12 rotates with the connected connecting rod 13, thereby driving the moving member 14 to slide on the guide rod 15, realizing the synchronous adjustment of the plurality of support legs 12.

[0036] In some embodiments, as Figures 1-3 shown, a first positioning hole 141 is provided on the moving member 14, and a plurality of second positioning holes 151 corresponding to the first positioning hole 141 are provided on the guide rod 15. The first positioning hole 141 and the second positioning hole 151 are connected by bolts.

[0037] Specifically, after the plurality of support legs 12 are spread out and the moving member 14 moves to a suitable position, the moving member 14 is fixed to the guide rod 15 by bolts. In this way, the moving member 14 will not move, thereby fixing the support legs 12 and making the support frame more stable.

[0038] In some embodiments, as Figures 1-3 shown, the rotating mechanism 2 includes a rotating table 21 and a mounting seat 22 provided on the rotating table 21. The rotating table 21 is rotatably provided on the top of the support base 11, and the rotating seat 32 is rotatably provided on the mounting seat 22.

[0039] Specifically, the rotating table 21 is rotatably provided on the mounting seat 22, which can drive the mounting seat 22 and the rotating seat 32 provided on the mounting seat 22 to rotate, and can realize the 360° rotation of the drilling device 5.

[0040] In some embodiments, as Figures 1-3 shown, a first fixing hole 211 is provided on the rotating table 21, and a plurality of second fixing holes 111 corresponding to the first fixing hole 211 are provided on the top of the support base 11. The first fixing hole 211 and one of the second fixing holes 111 are connected by a pin 23.

[0041] Specifically, a plurality of second fixing holes 111 are provided around the support base 11. After the operator controls the drilling device 5 to find the corresponding drilling position, the rotating table 21 rotates relative to the support base 11 to a suitable position, and the first fixing hole 211 and the second fixing hole 111 are plugged by a pin 23. In this way, the rotating table 21 can be fixed on the support base 11, avoiding the rotation of the rotating table 21 during drilling, which may cause the drilling to be inclined.

[0042] In some embodiments, as Figures 1-3 shown, a plurality of third fixing holes 212 are provided on the mounting base 22, and a fourth fixing hole corresponding to one of the third fixing holes 212 is provided on the side wall of the rotating base 32. One of the third fixing holes 212 is connected to the fourth fixing hole by a pin 23.

[0043] Specifically, the plurality of third fixing holes 212 are arranged along the rotation direction of the rotating base 32 relative to the mounting base 22. In this way, after the rotating base 32 rotates to a suitable position, the fourth fixing hole is connected to the corresponding third fixing hole 212 to fix the rotating base 32, facilitating the staff to drill holes and avoiding the rotation of the rotating table 21 during drilling, which may cause the drilling to be inclined.

[0044] In some embodiments, as Figures 1-3 shown, the drilling device 5 is installed on the mounting plate 31 through a sliding base 4. A slide rail 33 is provided on the mounting plate 31, the sliding base 4 is installed on the slide rail 33, and the drilling device 5 is fixed on the sliding base 4.

[0045] Specifically, the drilling device 5 is fixed on the sliding base 4, and the sliding base 4 is arranged on the slide rail 33. The construction worker can hold the drilling device 5 and push the drilling device 5 to control the drilling depth.

[0046] In some embodiments, as Figure 4 shown, a ground-gripping claw 6 is provided at the bottom of the support leg 12, and a claw tip 62 is provided at the bottom of the ground-gripping claw 6.

[0047] Furthermore, a cavity 120 is provided at the bottom of the support leg 12. One end of the ground-gripping claw 6 away from the claw tip 62 is provided with a connection head 61, and the connection head 61 rotates in the cavity 120.

[0048] Specifically, as Figure 4 shown, the ground-gripping claw 6 is rotatably provided at the bottom of the support leg 12. The ground-gripping claw 6 can rotate relative to the support leg 12, adapting to uneven ground and making the support of the support leg 12 more stable.

[0049] The specific use process of this application is as follows:

[0050] After the support frame and the drilling device 5 are brought to the position where drilling is required, the drilling device 5 is fixed on the sliding base 4, and then the support frame is supported to a suitable position, the support legs 12 are opened, and the gripping claws 6 are gripped to the ground. After reaching a suitable height, the movable member 14 and the guide rod 15 are connected by bolts through the first fixing hole 211 and the second fixing hole 111, so as to fix the movable member 14 and the guide rod 15, and then, they are rotated around the vertical direction, that is, the rotating table 21 is rotated on the support seat 11. After rotating to a suitable position, the first fixing hole 211 and the second fixing hole 111 are connected by the pin 23, so as to achieve the limit between the rotating table 21 and the support seat 11, and then the rotating seat 32 is moved. After reaching a suitable angle, the rotating seat 32 and the mounting seat 22 are fixed by the pin 23, and then the drilling device 5 is started, and the construction personnel push the drilling device 5 to control the drilling depth of the drilled hole.

[0051] After use, loosen the bolts, retract the support legs 12, and then fix the moving parts 14 and the guide rods 15. In this way, during the transportation process, the support legs 12 can be ensured not to be opened, ensuring safe transportation and avoiding personal injury to the staff caused by the opening of the support legs 12.
