Detailed Implementation

[0030] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0031] like Figure 1-9 As shown, a coal mine drilling rig that is easy to disassemble and maintain includes a platform 1; it also includes: a boss 3, which is fixedly installed on the top surface of the platform 1; a drilling rig body 2, the bottom of which is provided with a clamping and mounting mechanism 4, which is clamped and installed on the boss 3; the clamping and mounting mechanism 4 is provided with multiple pressure-applying components; a drive mechanism 5, which is provided with multiple output ends and one input end, and the multiple output ends are respectively connected to the multiple pressure-applying components, and the input end of the drive mechanism 5 is provided with a rocker arm 502; the drilling rig body 2 is provided with a sliding guide component, and the sliding guide component is connected to a lubrication mechanism 6.

[0032] like Figure 3-4As shown, as a specific technical solution, the clamping and mounting mechanism 4 includes a U-shaped frame 401; a plurality of first positioning posts 402 are fixedly installed on one side of the U-shaped frame 401, and the other side of the U-shaped frame 401 is connected to a plurality of pressure-applying components. The pressure-applying components include movable posts 404; a guide hole 403 is provided on the side wall of the U-shaped frame 401, the movable post 404 is slidably sleeved with the guide hole 403, the movable post 404 is provided with a second screw hole 407 along its length, the second screw hole 407 is threadedly connected with a stud 408, a pressure plate 405 is fixedly installed on one end of the movable post 404, and a second positioning post 406 is fixedly installed on the pressure plate 405. A plurality of first positioning holes 301 and a plurality of second positioning holes 302 are respectively provided on both sides of the boss 3, the first positioning posts 402 are engaged with the first positioning holes 301, and the second positioning posts 406 are engaged with the second positioning holes 302.

[0033] The drilling rig body 2 is mounted on top of the platform 1 via a clamping and mounting mechanism 4; during installation, the clamping and mounting mechanism 4 is initially in the following state: Figure 4 As shown, the pressure plate 405 is attached to the inner wall of one side of the U-shaped frame 401. By fastening the U-shaped frame 401 onto the boss 3, the U-shaped frame 401 is moved, causing the first positioning pin 402 to be inserted into the first positioning hole 301. Then, the drive mechanism 5 drives the studs 408 in all the pressure components to rotate. Through the threaded transmission between the studs 408 and the second screw hole 407, and with the guidance of the guide hole 403 and the movable pin 404, the movable pin 404, the pressure plate 405, and the second positioning pin 406 move together. The pressure plate 405 presses against the side wall of the boss 3, and with the other side of the U-shaped frame 401, the boss 3 is clamped, and the second positioning pin 406 is inserted into the second positioning hole 302, completing the installation. Figure 3 As shown.

[0034] When the clamping and mounting mechanism 4 is disassembled, the drive stud 408 is rotated in the opposite direction. Through the thread transmission between the stud 408 and the second screw hole 407, and the guidance between the guide hole 403 and the movable column 404, the movable column, the pressure plate 405 and the second positioning column 406 move together until the pressure plate 405 is in contact with the inner wall of one side of the U-shaped frame 401. Then the U-shaped frame 401 is moved to separate the first positioning column 402 from the first positioning hole 301, thus completing the disassembly.

[0035] like Figure 1 , Figure 3 as well as Figure 5As shown, as a specific technical solution, the drive mechanism 5 includes a protective shell 501; the protective shell 501 is fixedly installed on the outer wall of one side of the U-shaped frame 401, a rotating shaft 506 is rotatably installed inside the protective shell 501, one end of the rotating shaft 506 is fixedly connected to the rocker arm 502, a plurality of first bevel gears 503 are fixedly sleeved on the rotating shaft 506, and the plurality of first bevel gears 503 are all meshed with a second bevel gear 504, an inner frame 505 is fixedly installed inside the protective shell 501, the plurality of second bevel gears 504 are rotatably installed on the inner frame 505, and the ends of the studs 408 of the plurality of pressure-applying components are respectively fixedly connected to the plurality of second bevel gears 504.

[0036] The drive mechanism 5 operates as follows: by rotating the rocker arm 502, the rotating shaft 506 and the multiple first bevel gears 503 on the rotating shaft 506 rotate together. Through the meshing transmission between the first bevel gear 503 and the second bevel gear 504, the multiple studs 408 rotate synchronously together. By operating only a single rocker arm 502, the drive of all pressure components can be achieved.

[0037] In summary, when the drilling rig body 2 is disassembled or installed on the boss 3 via the clamping and mounting mechanism 4, only the rocker arm 502 needs to be rotated, making the disassembly and installation operations convenient and easy to disassemble and maintain.

[0038] like Figure 1 As shown, as a specific technical solution, the drilling rig body 2 includes a fixed frame 202; the fixed frame 202 is fixedly installed on the top surface of the U-shaped frame 401, a hydraulic rod 201 is fixedly connected to the fixed frame 202, a movable frame 203 is fixedly connected to the output end of the hydraulic rod 201, a motor 204 is fixedly installed on the movable frame 203, a drill rod 205 is connected to the output shaft end of the motor 204, and a drill bit 206 is connected to the drill rod 205. The sliding guide assembly includes a sliding sleeve 208; the sliding sleeve 208 is fixedly connected to the movable frame 203, a slide rail 207 is fixedly installed on the U-shaped frame 401, and the sliding sleeve 208 is slidably installed on the slide rail 207.

[0039] The drill rod 205 and drill bit 206 are rotated by the motor 204. At the same time, the hydraulic rod 201 extends and retracts, which drives the motor 204, the movable frame 203 and the sliding sleeve 208 to move together. The movement is guided by the sliding sleeve 208 and the slide rail 207, so that the rotating drill bit 206 enters the position to be drilled.

[0040] In specific implementation, a height adjustment and angle adjustment structure is set below the platform 1, as in the existing patent document "CN222350654U A mobile column-mounted emulsion drilling rig for coal mines".

[0041] like Figure 7-8As shown, the lubrication mechanism 6 includes a cylinder 601; a piston 605 is fitted inside the cylinder 601, and a screw 602 is rotatably connected to the piston 605. A nut seat 604 is provided at one end of the cylinder 601, and the screw 602 is threadedly connected to the nut seat 604. A turntable 603 is fixedly installed at the end of the screw 602 away from the piston 605. An oil cavity is formed between one side of the piston 605 and the inner wall of the cylinder 601. A port 606 is provided at one end of the cylinder 601, and the port 606 communicates with the oil cavity. A first threaded hole 2083 is provided on one side of the sliding sleeve 208, and one end of the cylinder 601 is threadedly connected to the first threaded hole 2083. The sliding sleeve 208 has an inner cavity 2081. Several evenly distributed oil outlet holes 2082 are formed on the inner side wall of the sliding sleeve 208, and the oil outlet holes 2082 communicate with the inner cavity 2081. The sliding sleeve 208 also has a connecting hole 2084 and a recessed hole 2085. The inner cavity 2081 communicates with the first screw hole 2083 through the connecting hole 2084 and the recessed hole 2085. The diameter of the recessed hole 2085 is larger than the diameter of the connecting hole 2084. A sealing ring 2086 is provided in the recessed hole 2085, and the port 606 is pressed onto the sealing ring 2086.

[0042] The sliding sleeve 208 and the slide rail 207 provide guidance for the movement of the movable frame 203, motor 204, drill rod 205 and drill bit 206, thereby improving the stability of the movement.

[0043] The lubrication mechanism 6 is provided to improve lubrication between the sliding sleeve 208 and the slide rail 207, thereby reducing friction and wear.

[0044] During lubrication, the screw 602 and the nut seat 604 are screwed together by rotating the turntable 603 in the forward direction. The screw 602 pushes the piston 605, which squeezes the lubricating oil in the oil chamber. The oil enters the inner cavity 2081 through the port 606 and the connecting hole 2084, and then flows from the oil outlet 2082 to the sliding sleeve 208 and the slide rail 207 to achieve lubrication of both. In order to determine the amount of injected oil, the cylinder 601 is made of transparent material and the surface is marked with scale.

[0045] When the oil in the cylinder 601 is insufficient, the cylinder 601 is loosened by turning it to separate it from the first threaded hole 2083, allowing the entire lubrication mechanism 6 to be removed. The port 606 of the lubrication mechanism 6 is then inserted into the container holding the oil. By turning the turntable 603 in the opposite direction, the piston 605 is moved away from the port 606, increasing the volume of the oil chamber. The oil is then drawn into the oil chamber through the port 606. Then, the cylinder 601 is screwed into the first threaded hole 2083. After screwing, the port 606 is inserted into the recessed hole 2085 and pressed against the sealing ring 2086.
