Description

Technical Field

[0001] This utility model relates to the field of positioning devices, and in particular to a precision drilling positioning device for blasting operations. Background Technology

[0002] Blasting is a construction method that uses the energy generated by the explosion of explosives to break or remove objects. It is widely used in mining, road construction, building demolition and other fields.

[0003] In existing technologies, before blasting operations, workers typically use drilling machines to drill holes in the ground for placing explosives. However, during drilling, workers' arms easily become fatigued from holding the drilling machine for extended periods. As fatigue intensifies, the arm muscles gradually begin to tremble involuntarily, causing the drilling machine to shake, resulting in a significant decrease in stability. This can lead to positioning deviations, affecting drilling accuracy. Furthermore, the shaking of the drilling machine can easily damage the drilling tools. Therefore, a precise drilling positioning device for blasting operations is needed. Utility Model Content

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-5 This utility model provides a precision drilling and positioning device for blasting construction, which includes a support plate 1. A first fan 3 is fixedly connected to the inner surface of the support plate 1. A connecting shaft 4 is fixedly connected to the output end of the first fan 3. A bearing frame 2 is fixedly connected to the upper surface of the connecting shaft 4. The outer surface of the connecting shaft 4 is rotatably connected to the support plate 1. The lower surface of the bearing frame 2 is in contact with the support plate 1.

[0028] A second motor 5 is fixedly connected to the upper surface of the support frame 2. A threaded screw 6 is fixedly connected to the output end of the second motor 5. A protrusion 7 is threadedly connected to the outer surface of the threaded screw 6. A slider 8 is fixedly connected to the side surface of the protrusion 7. The outer surface of the threaded screw 6 is rotatably connected to the support frame 2. The inner surface of the slider 8 is in contact with the support frame 2. A connecting arm 9 is fixedly connected to the right surface of the slider 8. A connecting plate 10 is fixedly connected to the end of the connecting arm 9 away from the slider 8. Two connecting rods 11 are fixedly connected to the support frame 2. Two screws 12 are movably connected to the inner surfaces of the two connecting rods 11. The same support rod 13 is fixedly connected to the corresponding two screws 12. Insert blocks 14 are fixedly connected to the lower surfaces of the two support rods 13. Nuts 15 are threadedly connected to the outer surfaces of the four screws 12. The first fan 3 and the second motor 5 are electrically connected to an external power source. A sliding groove 1 is provided on the support frame 2. 7. The outer surface of the protrusion 7 is slidably connected to the slide groove 17. The slide groove 17 allows the protrusion 7, slider 8 and other structures to move smoothly. The connecting rod 11 has a limiting groove 16. The outer surface of the screw 12 is movably connected to the limiting groove 16. Under the action of the limiting groove 16, the screw 12, support rod 13 and other structures can move smoothly. At the same time, it can limit the movement distance of the screw 12, support rod 13 and other structures to prevent the screw 12 and support rod 13 from detaching from the connecting rod 11. The outer surface of the support rod 13 is in contact with the connecting rod 11. The side surface of the nut 15 is in contact with the connecting rod 11. The lower surface of the connecting rod 11 is in contact with the support plate 1. The connecting plate 10 has four docking holes 18 arranged in a rectangular array. The drilling equipment and the whole device can be connected through the docking holes 18 reserved on the connecting plate 10.

[0029] Working principle: The drilling machine can be connected to the positioning device through the pre-drilled hole 18 on the connecting plate 10. By starting the first fan 3 on the support plate 1, the first fan 3 drives the connecting shaft 4 to rotate, thereby driving the bearing frame 2 and the structure on the bearing frame 2 to rotate. Because the drilling machine is connected to the connecting plate 10 through the drilling hole 18, the angle of the drilling machine can be adjusted. In some positions where it is inconvenient to move the entire device, the drilling machine can be moved to the corresponding drilling position by starting the first fan 3. After adjusting to the appropriate position, the nut 15 is rotated to unscrew the screw 12, thereby releasing the fixation of the screw 12, support rod 13, insert block 14 and other structures. At this time, the support rod 13 is flipped so that the support rod 13 and insert block 14 are aligned with the screw 12. The central shaft rotates, and then the support rod 13 moves downward, inserting the plug 14 into the ground. Then, the nut 15 is screwed back onto the screw rod 12, thus fixing the screw rod 12, support rod 13, and plug 14. Since the plug 14 is already inserted into the ground, the support rod 13 and plug 14 provide support for the entire device, preventing it from shaking. Then, the drilling machine is started. After the drilling machine starts, the second motor 5 on the support frame 2 is started, which drives the threaded screw 6 to rotate. The rotating threaded screw 6, under the action of the protrusion 7 and the slide groove 17, drives the slider 8, connecting arm 9, connecting plate 10, and the drilling machine on the connecting plate 10 to move downward. When the drilling machine gradually contacts the ground, the drilling work begins.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
