[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0028] like Figures 1 to 4 As shown, a percussion drill positioning device comprises an outer cylinder 3 and a moving frame 4 arranged in the outer cylinder 3, wherein the moving frame 4 comprises a split anchor plate, a split positioning hoop 48 fixed directly below the anchor plate, and adjustable supports respectively arranged on the outer peripheries of the anchor plate and the positioning hoop 48, wherein a wheel plate 46 is arranged at one end of the anchor plate of the adjustable support, and a rolling member 47 that can move vertically along the inner wall of the outer cylinder 3 is arranged on the wheel plate 46; an anchor hole 5 for anchoring a suspension rope is arranged at the center of the anchor plate;

[0029] When in use, open the anchor plate, and according to the stroke, pass the part of the sling rope above the drilling tool and above the ground through the anchor plate, close the anchor plate to lock the sling rope and fix it. The sling rope can only move under the guidance of the outer tube 3. At this time, the drilling tool is only affected by the sling rope under the mobile frame 4. Compared with the full length of the sling rope, the length of this section of the sling rope is shortened, thereby reducing or avoiding the shaking of the drilling tool when it falls.

[0030] The movable frame 4 is designed with two layers, which is equivalent to increasing the height in the vertical direction. It can ensure that the movable frame 4 always remains vertical and not tilted when the outer cylinder 3 moves, thereby ensuring the stability of the suspension rope when it moves up and down; the adjustable support can adjust the specific length according to the inner diameter of the outer cylinder 3. In addition, when it is necessary to adjust the drilling tool landing point in a small range, the position of the suspension rope can be adjusted directly by adjusting the position of each adjustable support, without adjusting the inclination angle of the hanger of the wire rope impact drill or the position of the wire rope impact drill.

[0031] Further, such as Figures 1 to 4 As shown, the impact drill positioning device also includes a plurality of vertically arranged wheel plates 46, the adjustable support of the anchor plate and the free end of the adjustable support installed on the positioning hoop 48 below the adjustable support are fixed on the same wheel plate 46; at least two rows of rolling elements 47 are arranged on the wheel plate 46, and the rolling elements 47 can be bull's eye wheels or directional wheels.

The second plate ears of the sub-hoop pieces are fixed by bolts. In actual use, since the second plate ears of the sub-hoop pieces can be directly fitted together to form a ring of the positioning hoop 48, the second plate ears do not need to be fixed by bolts, and the positioning hoop 48 can be spliced ​​into a ring only by relying on the action of the upper anchor plate.

[0034] In an optional embodiment, if Figure 3 As shown, the adjustable support includes a sleeve 43 fixed on the outer periphery of the anchor plate, a pipe seat 461 fixed on the wheel plate 46, and a support rod 44 connected to the sleeve 43 and the pipe seat 461; the support rod 44 can be selected to have different lengths as needed, and the support rod 44 is threaded or plugged into the sleeve 43 and the pipe seat 461.

[0036] In an optional embodiment, if Figure 4 As shown, the number of the sub-hoop pieces is consistent with the number of the sub-anchor plates 41, and the seams of the sub-hoop pieces and the seams of the sub-anchor plates 41 are almost corresponding up and down. A vertical connecting rod 49 is fixed between the positioning hoop 48 and the anchor plate, and the connecting rod 49 enhances the structural stability of the mobile frame 4.

[0037] In another optional embodiment, the positioning hoop 48 is a ring-shaped one having a notch for the entry and exit of the lifting rope, and there are two sub-anchor plates 41. A connecting rod 49 is fixed between one sub-anchor plate 41 and the positioning hoop 48, and the other sub-anchor plate 41 does not have a connecting rod 49. When it is necessary to fix the lifting rope, the sub-anchor plate 41 without the connecting rod 49 can be removed and re-fixed.

[0038] Further, such as Figure 5As shown, a cylinder plate 31 with a third mounting hole is fixed at the lower end of the outer cylinder 3, and the outer cylinder 3 is mounted on the bracket 2; the bracket 2 includes a mounting frame and legs 1 fixed at the four corners of the mounting frame, a through hole is provided in the middle of the mounting frame, the through hole extends to one side of the mounting frame, and longitudinal holes 23 are provided on both sides of the through hole; the mounting frame includes two second branch pipes 22 arranged in parallel, a first branch pipe 21 arranged in parallel on the outside of the second branch pipes 22, and a transverse pipe 24 fixed at one end of the inner side of the two second branch pipes 22; the first branch A longitudinal hole 23 is formed between the tube 21 and the second branch pipe 22, and a through hole is formed between the two second branch pipes 22; a mounting bolt vertically passing through the longitudinal hole 23 is arranged in the third mounting hole, and a gasket which is pressed against the lower side of the mounting frame is arranged at the lower part of the mounting bolt through a locking nut; when in use, first fix the position of the bracket 2, and pay attention to placing the mounting frame in a horizontal state when fixing it, and monitor whether it is in a horizontal state by fixing a level bubble on it, and then install the outer cylinder 3 on the bracket 2 according to the position of the drill hole, and set the outer cylinder 3 concentrically with the drill hole.
