[0035] The cooling assembly 3 includes a liquid storage tank 31 fixedly arranged on the upper side of the workbench 11, and the liquid storage tank 31 stores coolant. A first connecting pipe 32 is fixedly arranged at the liquid outlet of the liquid storage tank 31, and a switch valve is arranged on the first connecting pipe 32. The other end of the first connecting pipe 32 is fixedly arranged with the input end of a delivery pump 33, and the output end of the delivery pump 33 is fixedly arranged with a first hose 34. The first hose 34 is arranged so as not to hinder the up and down movement of the mounting plate 21. A second connecting pipe 324 is fixedly arranged at the other end of the first hose 34, and the second connecting pipe 324 is fixed on the lower side of the mounting plate 21. A three-way pipe 35 is fixedly arranged at the lower end of the second connecting pipe 324. A second hose 36 is fixedly provided on the lower side of the tube 35, and a first nozzle 37 is fixedly provided on the lower end of the second hose 36. The second hose 36 is provided so as not to hinder the rotation of the first nozzle 37. When cooling the hollow drill barrel 24, the coolant in the liquid storage tank 31 is transported from the first connecting pipe 32 to the first hose 34 through the delivery pump 33, and then transported to the second connecting pipe 324, and transported to the second hose 36 through the three-way pipe 35, and then the coolant is sprayed to the contact point between the hollow drill barrel 24 and the anchor plate through the first nozzle 37, so that the hollow drill barrel 24 is cooled while the hollow drill barrel 24 is drilling a hole in the anchor plate.

[0036] The first nozzle 37 is provided with a support rod 38 on one side close to the bracket 15, and a connecting sleeve 322 is rotatably provided on the support rod 38. A fixing rod 323 is fixedly provided on the upper side of the connecting sleeve 322, and the fixing rod 323 is fixedly connected to the lower side of the mounting plate 21. A gear 39 is fixedly provided on the other end of the support rod 38, and a sliding rod 310 is abutted on one side of the gear 39. A tooth groove section 311 is provided on the lower side of one end of the sliding rod 310 close to the gear 39, and the gear 39 can mesh with the tooth groove section 311. When the lower end of the hollow drill barrel 24 just abuts against the upper end surface of the anchor plate, the first nozzle 37 sprays coolant to the abutment surface of the hollow drill barrel 24 and the anchor plate, but as the hollow drill barrel 24 moves downward, the direction of the coolant sprayed by the first nozzle 37 will deviate from the drilling hole of the hollow drill barrel 24 on the plate, thereby affecting the drilling of the hollow drill barrel 24 has a cooling effect. When the hollow drill barrel 24 moves down to its lower end and abuts against the upper end of the anchor pad, the mounting plate 21 can simultaneously drive the fixing rod 323 and the connecting sleeve 322 to move downward, so that the support rod 38 moves downward, and the gear 39 moves down along the sliding rod 310 until it abuts against the upper side of the tooth groove section 311. When the hollow drill barrel 24 continues to move downward to drill a hole in the anchor pad, the support rod 38 continues to move downward, so that the gear 39 meshes with the tooth groove section 311, thereby driving the rotation of the gear 39, so that the support rod 38 rotates while moving downward, and then drives the first nozzle 37 to rotate upward toward the hollow drill barrel 24, so that it can follow the downward movement of the hollow drill barrel 24 and adjust the direction of the first nozzle 37, so that the coolant sprayed by the first nozzle 37 will not deviate from the hollow drill barrel 24, so that the coolant is sprayed to the contact point of the drilling hole between the hollow drill barrel 24 and the anchor pad.

[0037] A sliding bar 312 is fixedly provided on one side of the sliding bar 310 away from the gear 39, and a sliding groove plate 313 is slidably provided on one side of the sliding bar 312. The upper end of the sliding groove plate 313 is fixedly connected to the bracket 15, and a stud 314 is fixedly provided on the upper end of the sliding bar 312 away from the sliding bar 310. A through groove 315 is penetrated on the sliding groove plate 313, and the stud 314 penetrates the through groove 315 and extends to the outside. When the sliding bar 310 slides up and down along the sliding groove plate 313 through the sliding bar 312, the stud 314 slides along the through groove 315, and a fastening nut 316 is threadedly provided on the stud 314. For anchor pads of different thicknesses, when the lower end of the hollow drill barrel 24 abuts against the upper end of the anchor pad, the gear 39 may not be able to abut against the upper side of the tooth groove section 311 after moving downward, or it may have been meshed with the tooth groove section 311 and rotated a large range relative to the hollow drill barrel 24, which will affect the subsequent cooling effect of the hollow drill barrel 24. The height position of the tooth groove section 311 on the lower side of the slide rod 310 is adjusted by moving the slide rod 310 up and down and according to the thickness of the anchor pad. After the adjustment is completed, the position of the slide rod 310 is fixed by tightening the fastening nut 316.

[0038] The support rod 38 is fixedly provided with an adsorption plate 317 on the side away from the sliding rod 310, and a connecting rod 318 is provided on the upper end of the adsorption plate 317, and a sleeve rod 319 is slidably provided on the connecting rod 318, and the upper end of the sleeve rod 319 is fixedly connected to the mounting plate 21, and a magnetic block 320 that is magnetically attracted to the adsorption plate 317 is fixedly embedded at the lower end of the connecting rod 318. The magnetic attraction and fixing effect of the magnetic block 320 and the adsorption plate 317 can maintain the initial orientation angle of the first nozzle 37, and prevent the support rod 38 from rotating when the support rod 38 moves downward. When the gear 39 is engaged with the tooth groove section 311 and the support rod 38 continues to move downward to cause the gear 39 to rotate, the rotation of the support rod 38 will drive the adsorption plate 317 to rotate downward, so that the adsorption plate 317 is separated from the magnetic block 320, and the upper end of the connecting rod 318 and the bottom end of the inner cavity of the sleeve rod 319 are fixedly engaged with the magnetic block 320. A spring 321 is fixedly provided. When the mounting plate 21 drives the hollow drill tube 24 to move upward and reset, the setting of the spring 321 can prevent the support rod 38 from rotating excessively, causing the initial inclination angle of the first nozzle 37 to change. When the support rod 38 rotates excessively or not in place, the adsorption plate 317 can be rotated back to a horizontal state with the magnetic attraction of the magnetic block 320 through the spring 321 and the magnetic attraction of the magnetic block 320 to the adsorption plate 317, so as to ensure the initial inclination angle of the first nozzle 37. Limiting blocks are symmetrically fixed on both sides of the upper end of the support rod 38, and limiting grooves are symmetrically provided on both sides of the inner cavity of the sleeve rod 319. The limiting blocks slide in the limiting grooves. When the limiting blocks are located at the lower end of the limiting grooves, the spring 321 is in the initial state, and at this time, the adsorption plate 317 is in a horizontal position and is magnetically fixed with the magnetic block 320. Embodiment 3

[0039] The auxiliary component 4 includes a ring 41 rotatably arranged with the mounting block 23. The upper side of the ring 41 is rotatably connected to the upper side of the mounting block 23 through a bearing 42. A groove for placing the bearing 42 is provided on the upper side of the ring 41. An annular cavity 43 is opened on the inner side of the ring 41. A third connecting pipe 44 connected to the annular cavity 43 is fixedly arranged on one side of the ring 41. The end of the third connecting pipe 44 away from the ring 41 is fixedly connected to the three-way pipe 35. On the basis of embodiments one and two, the second connecting pipe 324 is fixed to the mounting plate 21 through the three-way pipe 35 and the third connecting pipe 44, which can keep the ring 41 in a fixed state, so that when the driving motor 22 drives the mounting block 23 to rotate, the ring 41 will not rotate, and the mounting block 23 rotates in the ring 41 through the bearing 42.

[0040] The inside of the mounting block 23 is evenly provided with flow holes 45 connected to the annular cavity 43 around the circumference, and a fourth connecting pipe 46 connected to the flow hole 45 is fixedly provided in the middle of the mounting block 23. The fourth connecting pipe 46 passes through the top of the hollow drill tube 24 and extends to the lower side. The lower end of the fourth connecting pipe 46 is fixedly connected to a mounting plate 47, and a second nozzle 48 is evenly fixedly provided on the lower side of the mounting plate 47. The coolant delivered to the second connecting pipe 324 by the delivery pump 33 can enter the third connecting pipe 44 through the other interface of the three-way pipe 35, and then The coolant enters the annular cavity 43, passes through the circulation hole 45, enters the fourth connecting pipe 46, and is further transported to the inner cavity of the mounting plate 47, and is sprayed out through the second nozzle 48. Therefore, when the core plate after drilling is stuck in the hollow drill barrel 24, the sprayed coolant can flush the core plate out, thereby conveniently cleaning out the core plate stuck in the hollow drill barrel 24 after drilling. At the same time, the coolant sprayed out through the second nozzle 48 can cool down the inner surface of the hollow drill barrel 24, thereby increasing the cooling effect on the hollow drill barrel 24.

[0041] Annular blocks 49 are symmetrically fixedly arranged on the lower side of the mounting block 23. The two annular blocks 49 are respectively located on the upper and lower sides of the circulation hole 45. Annular grooves 410 adapted to the annular blocks 49 are symmetrically opened on the inner side of the collar 41. The two annular grooves 410 are respectively located on the upper and lower sides of the annular cavity 43. The two annular blocks 49 are respectively inserted into the two annular grooves 410. Sealing gaskets 411 are fixedly arranged on the side walls of the annular grooves 410. The sealing gaskets 411 can seal the gap between the annular block 49 and the collar 41 to prevent the coolant from leaking from between the collar 41 and the mounting block 23.
