Detailed Implementation

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-5 As shown, this utility model provides a cooling device for a hydraulic anchor bolt drilling rig in a coal mine, including a base plate 1. Track wheels 2 are symmetrically installed on the lower end of the base plate 1. Tracks 3 are sleeved on the outside of the track wheels 2. An adjustment mechanism 4 is provided on the upper end of the base plate 1. A mounting plate 5 is provided at the top of the adjustment mechanism 4. An oil tank 6 is fixedly installed on one side of the upper end of the mounting plate 5. A pump station 7 is fixedly installed on the other side of the oil tank 6. A cooling mechanism 8 is provided on the rear side of the upper end of the mounting plate 5. A side plate 9 is fixedly installed on the right side of the upper end of the mounting plate 5. A hydraulic cylinder 10 is fixedly installed at one end of the side plate 9. A slide 11 is fixedly installed at the top of the output rod of the hydraulic cylinder 10. A motor 12 is fixedly installed on one side of the slide 11. A vertical plate 13 is fixedly installed on the left side of the upper end of the mounting plate 5. A drill rod 14 is driven and installed at the output end of the motor 12. A drill bit 15 is fixedly installed at the top of the drill rod 14.

[0025] A groove 16 is provided in the middle of the upper end of the mounting plate 5, and a slider 17 is fixedly provided at the lower end of the slide block 11.

[0026] The slider 17 is fitted into the groove 16 and is slidably installed.

[0027] A circular hole is provided through the middle of the vertical plate 13, through which the drill rod 14 and the drill bit 15 can pass respectively through the circular hole and the annular tube 87. The outside of the drill rod 14 is in contact with the inside of the limiting plate 46.

[0028] In this design, the slide block 17 can be driven to slide synchronously in the slide groove 16 through the slide block 11, thereby improving the movement effect of the slide block 11. The round hole in the middle of the vertical plate 13 facilitates the rotation of the drill rod 14.

[0029] like Figures 3-4 As shown, the adjustment mechanism 4 includes a cylinder 41. The bottom end of the cylinder 41 is symmetrically fixed to the four corners of the upper end of the base plate 1. Fixing plates 42 are symmetrically fixed on both sides of the lower end of the mounting plate 5. A rotating shaft 43 is rotatably installed on the inner side of the fixing plate 42. A sleeve block 44 is rotatably sleeved on the outer side of the rotating shaft 43. Springs 45 are symmetrically fixed on the inner wall of the inner round hole of the vertical plate 13. A limiting plate 46 is fixed on the top of the spring 45.

[0030] The top end of the output rod of cylinder 41 is fixedly connected to the lower end of sleeve block 44, and the limiting plate 46 is arc-shaped.

[0031] In this design, when the four sets of cylinders 41 extend synchronously, the mounting plate 5 can be lifted smoothly. When one side of the cylinder 41 is controlled to work, the angle of the drill rod 14 in the drilling machine can be adjusted. When the drill rod 14 passes through the round hole in the middle of the vertical plate 13, the compressed spring 45 can push the limiting plate 46 closer to the surface of the drill rod 14, so that the limiting plate 46 fits against the outside of the drill rod 14. This ensures the stability of the drill rod 14 during rotation, making it less prone to shaking, and thus improving the overall work efficiency.

[0032] like Figure 5 As shown, the cooling mechanism 8 includes a water tank 81. The lower end of the water tank 81 is fixedly connected to the rear side of the upper left end of the mounting plate 5. A water injection pipe 82 is fixedly provided at the upper end of the water tank 81. A drain pipe 83 is fixedly provided at the front end of the water tank 81. A water pump 84 is fixedly provided at one end of the water tank 81. A delivery pipe 85 is fixedly provided at the rear side of the water pump 84. Multiple sets of fixedly connected support rods 86 are distributed in a circular shape at equal intervals on one side end of the vertical plate 13. A ring pipe 87 is fixedly provided at the top of the support rod 86. Multiple sets of equally distributed nozzles 88 are fixedly provided on the inner side of the ring.

[0033] A valve is installed on the drain pipe 83, and the top end of the delivery pipe 85 is fixedly connected to the upper end of the ring pipe 87.

[0034] The nozzle 88 is connected to the water pump 84 through the ring pipe 87 and the delivery pipe 85.

[0035] In this design, a ring pipe 87, also made of stainless steel, is fitted around the drill rod 14. Multiple nozzles 88 are evenly distributed on the ring pipe 87. These nozzles are designed to atomize the water flow into a fine mist, which is used to spray and cool the working drill rod 14. The operator replenishes water to the water tank 81 via the water inlet pipe 82 to ensure continuous and stable cooling. When the water in the tank 81 becomes dirty due to prolonged use, the wastewater can be drained through the drain pipe 83 and clean water can be refilled to maintain the system's cooling efficiency. The valve on the drain pipe 83 controls its opening and closing.

[0036] The working principle of the cooling device for the hydraulic anchor drilling rig used in this coal mine will be explained in detail below.

[0037] like Figures 1-5 As shown, when the cooling device for the hydraulic anchor bolt drilling rig in the coal mine is in use, after starting the cylinder 41, the cylinder 41 can simultaneously push the sleeve block 44 upward, so that the sleeve block 44 can drive the mounting plate 5 to move upward, so that the mounting plate 5 can drive the drill rod 14 and the drill bit 15 to move synchronously, thereby adjusting the working height of the drill rod 14. When one side of the cylinder 41 is started, the cylinder 41 on that side pushes the sleeve block 44 on that side upward, so that the mounting plate 5 can be tilted with the sleeve block 44 on the other side and the rotating shaft 43 as the fulcrum, thereby adjusting the working angle of the drill rod 14 and the drill bit 15. By starting the hydraulic cylinder 10 and the motor 12, the hydraulic cylinder 10 can push the slide 11 to move on the mounting plate 5, while the motor 12 can drive the drill rod 14 and the drill bit 15 to rotate for drilling. By starting the water pump 84, the water pump 84 quickly draws water from the water tank 81 and pressurizes it. The water flows quickly along the delivery pipe 85 to the ring pipe 87. The water in the ring pipe 87 is then sprayed evenly onto the drill rod 14 through the nozzle 88. As the temperature of the drill rod 14 rises, the water mist continuously evaporates and absorbs heat, continuously carrying away heat to achieve a cooling effect and effectively improve the service life of the drilling machine.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
