[0048] In this embodiment, as shown in Figures 3-4 , the bottom end of the bottom layer support leg A1 is further fixedly connected with a base plate A5.

[0049] In this embodiment, the bottom support frame, the middle layer support frame and the top layer support frame are made of steel. Specifically, a plurality of bottom layer support legs A1 are welded and fixed with the bottom layer outer frame A4, the upper surface of the bottom layer outer frame A4 is further welded and fixed with a plurality of bottom layer clamping feet A3, and part of the bottom layer support legs A1 are welded and fixed through the bottom layer sweeping rod A2; a plurality of middle layer support legs B1 are welded and fixed with the middle layer outer frame B4, the upper surface of the middle layer outer frame B4 is further welded and fixed with a plurality of middle layer clamping feet B3, and part of the middle layer support legs B1 are welded and fixed through the middle layer sweeping rod B2; a plurality of top layer support legs C1 are welded and fixed with the top layer outer frame C4, and part of the top layer support legs C1 are welded and fixed through the top layer sweeping rod C2.

[0050] The welding method of the bottom support frame is as follows: first, a rectangular frame (2 meters long, 0.3 meters, 0.512 meters and 0.724 meters wide respectively) at the top is welded using a 6-inch steel pipe (5mm thick) to form a bottom layer outer frame A4 as shown in the figure. Figure 6 Then, the bottom layer support leg A1 is welded on the bottom layer outer frame A4, the side of the bottom layer support leg A1 is offset by 12 degrees to both sides, the front is kept vertical, the length is 0.5 meters, and attention should be paid to ensure the angle and length of the bottom layer support leg A1; the bottom layer support leg A1 is placed upside down and placed vertically, the height of the steel frame is measured, and the bottom layer support leg A1 is marked (the line should be marked horizontally, not vertically) at a vertical height of 0.5 meters, and the excess part is cut off; a 30mm diameter, 5mm thick circular steel plate is used to weld and close the steel pipe opening of the bottom layer support leg A1 (the lowermost layer is used) to form a base plate A5; the bottom layer sweeping rod A2 is welded at a vertical height of 0.1 meters of the bottom layer support leg A1, two long bottom layer sweeping rods A2 are welded on the front (each long bottom layer sweeping rod A2 is connected with three bottom layer support legs A1 at the same time), and two short bottom layer sweeping rods A2 are welded on the side (each short bottom layer sweeping rod A2 is connected with two bottom layer support legs A1 at the same time, and the two bottom layer support legs A1 are connected with two corner positions of the bottom layer outer frame A4 in the width direction); short steel pipes (as cross bars A41) are welded inside the bottom layer outer frame A4 at an interval of 100mm; circular steel plates (diameter 30mm, thickness 5mm, as the circular bottom plate A31 in the horseshoe-shaped clamping foot) are welded at the corresponding position of the bottom layer outer frame A4 above each bottom layer support leg A1, wherein the four corner positions of the circular steel plate are respectively placed on the top corners of the bottom layer outer frame A4 and the two sides of the bottom layer outer frame A4. The center of the circular steel plate corresponds to the center of the top of the lower bottom layer support leg A1, and is welded and fixed above the bottom layer outer frame A4; a steel pipe with an inner diameter of 30mm and an outer diameter of 40mm is selected, cut to a height of 25mm, and then cut in half to form a semicircular wall A32, which is welded on the circular steel plate according to the design. Thus, the bottom support frame is completed.

[0051] The working mode of the upper two layers is basically the same as the above, and the difference is the change of the width size, and the top support frame is not arranged with the horseshoe-shaped clamping feet.

[0052] The embodiment is layered and superimposed, each layer has a height of 0.5 m, three layers have a height of 1.5 m, and the height meets the drilling operation requirement of 4-4.5 m of the underground stope. Figure 2 As shown in the side view, the bottom layer support legs A1 on both sides of the bottom layer support frame are respectively inclined to both sides by 12 degrees, forming an "eight" shape, and the stability of the support frame is greatly improved; the middle layer support legs B1 in the middle layer support frame are also inclined by 12 degrees, and the span is the width of the top surface of the bottom layer support frame; the top layer is the same, and the three-layer support frame (the bottom layer support frame, the middle layer support frame and the top layer support frame) can be reasonably overlapped. Each layer of support frame (the bottom layer support frame, the middle layer support frame and the top layer support frame) can be used alone or stacked and used. A plurality of section steel pipes (spacing 10 cm, that is, cross bars A41) are welded in the outer frame (length 2 m, width according to design) of each layer to facilitate personnel to stand on it, and the space between the steel pipes, the length and width of the top surface meet the requirement of erecting the air drill on site. Each layer of support frame is arranged with six support legs, which greatly improves the stability, and six horseshoe-shaped clamping feet are welded above the corresponding positions of the outer frame on the top of the support legs of the bottom layer and the middle layer, which facilitates the placement of the support frame and prevents the upper support frame from sliding. After reasonable evaluation and calculation of each steel frame in the embodiment, it is ensured that one person can carry each layer of support frame, and the lightness is an important advantage.

[0053] The on-site operation mode is very simple, the bottom layer support frame is first placed, then the second layer (the middle layer support frame) is added and placed, that is, the middle layer support legs B1 of the middle layer support frame are inserted into the bottom layer clamping feet A3; then the third layer (the top layer support frame) is added, that is, the top layer support legs C1 of the top layer support frame are inserted into the middle layer clamping feet B3; after the placement is determined to be stable, the air drill is first lifted and placed on the top layer support frame, then the worker climbs onto the top layer support frame, and the operation can be performed after the preliminary preparation. When disassembling, the top layer support frame is removed from the middle layer clamping feet B3, and the middle layer support frame is removed from the bottom layer clamping feet A3. The disassembly and assembly are very simple and convenient.

[0054] The support frame can be used flexibly according to the on-site requirement, but attention should be paid to placing the support frame in a stable area at the bottom.

[0055] The utility model solves the problem of insufficient on-site operation height, and at the same time, in order to meet the on-site requirement, the weight is reduced as much as possible and the operation safety factor is improved, the convenience can greatly save the physical strength of workers and speed up the operation progress.

[0056] The protection scope of the utility model includes but is not limited to the above-mentioned embodiments, and the protection scope of the utility model is subject to the claims, and any replacement, deformation and improvement of the technology made by the person skilled in the art falls within the protection scope of the utility model.
