[0002] Drilling equipment is a mechanical device used to drill holes in solid materials. It is widely used in construction, mining, petroleum, railways and other industries. Drilling equipment is widely used in construction, mining, petroleum, railways and other industries for piling, laying pipelines, geothermal drilling, prospecting, oil production and other operations.

[0003] Stone mining is the process of excavating stones that meet the requirements from the original site and transporting them to the designated location, and filling them into the construction process of a building according to the design requirements. Stone mining generally includes drilling method, deep hole step blasting method, medicine pot blasting method, and chamber blasting method.

[0018] 1. The present invention realizes a method of aligning the axis without complicated procedures by setting a transmission mechanism and a limit plate. The drilling equipment body can be automatically aligned with the axis by simply lowering the drilling equipment body directly, pressing it on the mounting ring, and then using the transmission mechanism to drive the limit plate to limit and squeeze the middle.

At the same time, the four gears rotate during the rising process of the rack, so that the four limit plates are away from the axial center. At this time, there is a certain distance between the four limit plates and the side walls of the drilling equipment body. Then the drilling equipment body continues to be lowered, and the mounting ring is pressed downward again. At the same time, the rack moves downward again, driving the gear to rotate, and the four limit plates re-clamp the drilling equipment body at the axial center, so that the drilling equipment body is fixed more stably. The above operation realizes the re-positioning of the drilling equipment body by reusing the limit plate, eliminates the unstable influence of the drilling equipment body after the limit plate releases the drilling equipment body during the resetting process of the rack, and increases the limiting stability performance of the device on the horizontal plane for the drilling equipment body.

[0020] 3. The present invention provides a cleaning roller and a ball screw, so that during the descent of the top plate, the cleaning roller can rotate to clean the limit plate, and the bristles can be used to clean the dust and impurities on the limit plate, thereby preventing the dust or impurities on the limit plate from affecting the positioning operation. Compared with the traditional motor plus cleaning roller rotation cleaning operation, this linkage method does not require electronic control components, has low cost and low power consumption.

[0021] 4. The present invention realizes further cleaning and collection of dust on the brush of the side wall of the cleaning roller through the setting of the dust suction component, thereby ensuring the cleaning effect of the cleaning roller and further ensuring the limiting alignment function of the limit plate on the drilling equipment body. During the lowering process of the top plate, the top rod and piston of the dust suction component realize the process of timely cleaning and collection of dust scraped off by the scraper. Compared with traditional dust suction devices, this linkage mode does not require additional electronic control devices, has high fault tolerance, low failure rate and low cost.

[0044] Working principle: The drilling equipment body 38 is lifted by a crane and set above the erection structure. Then the drilling equipment is slowly lowered by the crane. The drill bit does not need to be aligned with the mounting hole 9 and can be directly lowered.

Considering that the environment of stone mining is dusty, when During the downward movement of the rack 13, the top plate 14 also moves downward, and the top plate 14 drives the ball screw 29 to move downward. Since the cleaning roller 26 is rotatably connected to the fixed seat 25, during the downward movement of the ball screw 29, the cleaning rollers 26 on both sides of the limit plate 19 rotate to clean the limit plate 19. The cleaning rollers 26 are provided with bristles, and the dust and impurities on the limit plate 19 can be cleaned by the bristles to prevent the dust or impurities on the limit plate 19 from affecting the positioning operation. The setting of the scraper 27 can further clean the dust on the surface of the cleaning roller. When the scraper 27 descends to the top of the cleaning roller 26, the top rod 23 under the piston 33 contacts the support rod 24, and the scraper As the cylinder 27 continues to descend, the scraper cylinder 27 scrapes off the dust on the brush on the side wall of the cleaning roller 26, while the push rod 23 drives the piston 33 to move upward, and the air inlet pipe 32 and the dust suction pipe 30 at the bottom of the dust suction bucket 21 pass through the cavity 36 inside the scraper cylinder 27 and the dust suction holes 37 on the inner wall, and suck the dust scraped off from the inside of the scraper cylinder 27 into the inside of the dust suction bucket 21.
