Description

Technical Field

[0001] The invention belongs to the technical field of coal mine drilling, and in particular relates to a drilling, punching and expanding integrated device. Background Art

[0002] Coal mine gas disasters rank first among the five major disasters in my country's coal mines, including gas, water, fire, roof and coal dust. Gas explosions, with their significant characteristics such as strong destructiveness, large economic losses and many deaths, pose a serious threat to coal mine production safety.

[0003] The main means of coal seam gas control is extraction through drilling, that is, drilling holes in coal seams with drilling rigs. After drilling the gas extraction hole, the cross-sectional area of ​​the hole is usually small, which is not conducive to gas extraction. Therefore, it is necessary to withdraw the drill bit from the gas extraction hole, and then use a hydraulic machine to perform hydraulic permeability enhancement and punching. The whole process not only consumes a lot of manpower, material and financial resources, but also the hydraulic machine cannot operate normally when the hole collapses. In addition, some drilling and expansion mostly use large drill bits, which need to be pulled back and forth to discharge slag, and are prone to explosion drilling, and the work efficiency is also low.

[0004] Therefore, a new drilling equipment is needed to solve the above problems. Summary of the invention

[0018] The drill rod 7 comprises a secondary cylinder 9-3 rotatably mounted on the bracket 10, one end of the secondary cylinder 9-3 is connected to one end of the main cylinder 9-2, and the other end of the main cylinder 9-2 is provided with a drill bit 9-1; a plurality of receiving grooves 9-4 are circumferentially provided on the main cylinder 9-2, and the left and right side walls of the receiving grooves 9-4 are provided with support cylinders 9-5, and the support cylinder 9-5 is hingedly provided with wing claws 9-6 with cavities, and the wing claws 9-6 are provided with a plurality of water outlets. Hole 9-7, both sides of the wing claw 9-6 are provided with a shift rod 9-9, and the support tube 9-5 is provided with a torsion spring 9-8 for the shift rod 9-9. In a natural state, the torsion spring 9-8 forces the wing claw 9-6 to be received in the receiving groove 9-4; the support tube 9-5 is connected to the main cylinder body 9-2 and the inner cavity of the wing claw 9-6; when the wing claw 9-6 is opened from the receiving groove 9-4, the rotating end of the wing claw 9-6 gradually moves away from the drill bit 9-1.

[0019] A pad for the wing claw 9-6 is provided in the above-mentioned storage groove 9-4.

[0020] The gear transmission structure 12 comprises a driven gear fixedly mounted on the auxiliary cylinder 9 - 3 and a driving gear fixedly mounted on the power output end of the driving motor 11 , and the driving gear and the driven gear are meshed with each other.

[0021] In order to facilitate the delivery of water into the drill rod 7, a high-pressure water pump 16 electrically connected to the controller 17 is also provided on the top plate 4. The water inlet of the high-pressure water pump 16 is connected to one end of the water supply pipe, and the water outlet of the high-pressure water pump 16 is rotatably connected to the end of the auxiliary cylinder 9-3 through a rotating joint.

[0022] It should be noted that when the wing claw 9-6 is in the receiving groove 9-4, multiple water outlet holes 9-7 are respectively opened on the side of the wing claw 9-6 close to the bottom of the receiving groove 9-4 and on the end of the wing claw 9-6 away from the support tube 9-5. During the drilling process of the drill rod 7, in order to prevent debris from clogging the water outlet holes 9-7, the end of the wing claw 9-6 away from the support tube 9-5 is a slope.

[0023] The specific working principle of the present invention is as follows: first, the device is moved to the working surface position to be drilled, and the drilling height of the drill rod 7 is adjusted by adjusting the telescopic end position of the hydraulic cylinder 5, then the drive motor 11 is started, the drill rod 7 starts to rotate, and the staff holds the grip 15 to advance the device. As the drill bit 9-1 gradually goes deeper, a hole is formed. Then, the high-pressure water pump 16 is started before the receiving groove 9-4 enters the hole. Then, the wing claw 9-6 opens and sprays high-pressure water to the drilling position. As the hole gradually deepens, the wing claw 9-6 starts to expand the hole along the hole, and the debris is discharged along the hole with the water flow.

[0024] After drilling is completed, the high-pressure water pump 16 is turned off first. Under the action of the torsion spring 9-8, the wing claw 9-6 enters the receiving groove 9-4, and the device is withdrawn backward. After the drill bit 9-1 comes out, the drive motor 11 is turned off and the drilling is completed.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
