Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a high-speed compact pressure relief drilling rig. Background Technology

[0002] A pressure relief drilling rig is a piece of equipment used in underground mining, primarily to deal with high-pressure ore layers deep in the mine. Due to the presence of large amounts of magma and groundwater deep in the mine, the safety of miners is greatly threatened. Therefore, pressure relief drilling rigs are needed to reduce the pressure within the ore layer and ensure the safety of miners. During operation, pressure relief drilling rigs generate a significant amount of noise and vibration, which greatly affects miners. Due to the instability of the drill bit, manual operation is required during drilling. During drilling, the friction of the drill bit as it drills into the rock wall causes debris to fly out, as shown in the image. This reduces drilling efficiency and also poses a safety hazard to the operators. Summary of the Invention

[0022] Reference Figures 1-4An embodiment of the present invention proposes a high-speed compact pressure relief drilling rig for operation in a well. It includes a body 1, a drill arm 2 hinged to the body 1, the drill arm 2 having a first sliding cavity 201 with an outlet 202, and the drill arm 2 also having a guide shell 203 located on one side of the outlet 202. The drill body 3 is slidably disposed in the first sliding cavity 201, and a sliding block 4 is slidably disposed in the guide shell 203. The body 1 drives the drill arm 2 to move so that the sliding block 4 contacts the well wall and pushes the sliding block 4 to slide. A rack 5 is disposed on the sliding block 4, and a gear 7 is disposed on the rotating shaft of the chuck 6 and meshes with the rack 5. After the gear 7 rotates, it drives the chuck 6 to rotate.

[0023] In this embodiment, considering that the drilling process is difficult and prone to deviation due to the varying rock wall inclination angles and surface roughness, a manual operation station is set up at the drilling rig's working position. Furthermore, considering that existing drilling rigs have high degrees of freedom and can operate flexibly in multiple directions, this design includes a drill arm 2, hinged to the rig body 1 at a position that allows for multi-directional sliding or rotation, enabling drilling operations on rock walls at different positions and angles. A first sliding cavity 201 is provided on the drill arm 2, within which the drill body 3 slides. The angle of the rotating arm determines the specific feed direction of the drill body 3, allowing for stable drilling direction of the drill body 3 simply by adjusting the direction and position of the rotating arm, thus initially meeting the requirement of no manual operation. A guide shell 203 is provided on the side of the drill arm 2. The sliding block 4 slides inside the guide shell 203. The sliding block 4 acts as a probe. When the sliding block 4 contacts the rock wall, it slides inside the guide shell 203. A rack 5 is provided on the sliding block 4. After the sliding block 4 slides, it meshes with the gear 7 on the chuck 6 rotatably provided on the guide shell 203, driving the chuck 6 to rotate. When the chuck 6 rotates inward, the chuck will stabilize the drill arm 2 near the part to be processed on the rock wall by gripping the irregular surface of the rock wall, making the drilling direction of the drill body 3 more stable.

[0024] Furthermore, the drill arm 2 includes a first telescopic arm 204 hinged to the vehicle body 1, a second telescopic arm 205 slidably disposed within the first telescopic arm 204, and a third telescopic arm 206 slidably disposed within the second telescopic arm 205.

[0025] In this embodiment, the drill arm 2 is configured to be telescopic, consisting of three telescopic sections. The first telescopic arm 204 is located on the side hinged to the vehicle body 1, and the third telescopic arm 206 is located on the side near the drilling area of ​​the rock wall. During operation, the telescopic process is as follows: the second telescopic arm 205 and the third telescopic arm 206 simultaneously extend forward initially, reaching a position a certain distance from the working area. Then, the third telescopic arm 206 extends from the second telescopic arm 205 to abut against the rock wall. The second telescopic arm 205 then extends forward again, sliding to the position of the third telescopic arm 206. This three-section telescopic design can meet the drilling distance requirements in most situations in roadways or underground. Simultaneously, when the third telescopic arm 206 abuts against the rock wall and enters the working state, the second telescopic arm 205 extends forward, acting as a support shell to prevent the third telescopic arm 206 from deforming due to unstable lateral stress during drilling.

[0026] Furthermore, it also includes a first rotating rod 8 with one end hinged to the second telescopic arm 205, a second rotating rod 9 with one end hinged to the third telescopic arm 206, and the first rotating rod 8 and the second rotating rod 9 being hinged together.

[0027] In this embodiment, considering that the head of the drill arm 2 can only provide a certain degree of stability for small deformations during drilling, and that large-scale vibrations caused by the movement of the drill arm 2 itself, the movement of the vehicle body 1, or the vibration of the drilling device can cause the chuck 6 to fall off and be damaged, as well as the drill body 3, or even drilling errors that could endanger personnel, this solution provides a first rotating rod 8 and a second rotating rod 9 hinged to the second telescopic arm 205 and the third telescopic arm 206. The first rotating rod 8 and the second rotating rod 9 are hinged. When the third telescopic arm 206 slides into the second telescopic arm 205, the angle between the first rotating rod 8 and the second rotating rod 9 increases. At the same time, the hinge point of the first rotating rod 8 and the second rotating rod 9 is close to the rock wall. Through the setting of the support structure, the first rotating rod 8 and the second rotating rod 9 can provide a multi-directional stabilizing effect on the drill arm 2. During the extension process, the angle between the first rotating rod 8 and the second rotating rod 9 increases, preventing the extension process from affecting the working position, and also preventing the first rotating rod 8 and the second rotating rod 9 from being obstructed by environmental factors during the movement.

[0028] Furthermore, it also includes a guide shell 10 disposed on the second rotating rod 9, the guide shell 10 having a second sliding cavity 1001, and the support member 11 being slidably disposed within the second sliding cavity 1001.

[0029] In this embodiment, a support member 11 is provided on the second rotating rod 9 to provide stable support between the rock wall and the drill arm 2. Since the surface height of the rock wall is different at different positions, a guide shell 10 is provided on the second rotating rod 9. The support member 11 is slidably disposed in the guide shell 10. The support member 11 can be slidably adjusted according to the specific surface position, so that the device can achieve more stable and adaptable drilling stability in complex operating environments such as tunnels or underground rock walls.

[0030] Furthermore, the guide shell 10 also has a longitudinal through groove 1002 that penetrates the second sliding cavity 1001. There are two stops 12, both of which are slidably disposed in the through groove 1002. Each stop 12 has an inclined surface 1201. The inclined surfaces 1201 of the two stops 12 are arranged opposite to each other and symmetrically. The rotating roller 13 is rotatably disposed on the support member 11. After the support member 11 slides in the second sliding cavity 1001, the rotating roller 13 and the inclined surface 1201 roll into contact. One end of the first elastic member 14 acts on the inner wall of the guide shell 10, and the other end acts on the support member 11, providing a force for the support member 11 to slide out of the second sliding cavity 1001. The two ends of the first elastic member 14 act on the two stops 12 respectively, providing a force for the two stops 12 to move closer to each other.

[0031] In this embodiment, considering that flying debris will be generated at the drill body 3 and the rock wall during the drilling process, which may easily cause injury to the operators and observers, two upper and lower stops 12 are also provided to slide in the through groove 1002 opened in the guide shell 10. The stops 12 have inclined surfaces, and a second elastic element 15 is provided between the two stops 12. When the support member 11 is extended, the roller 13 on the support member 11 slides on the inclined surface and moves the two stops 12 away from each other. The unfolded stops 12 isolate some of the flying debris, ensuring the safety of personnel and equipment. When the support member 11 is pushed and slid, it triggers the stops 12. After being pushed back to the rock wall by the first elastic element 14, the stops 12 are reset. Stable and safe changes in working state are achieved without the need for an additional power source.

[0032] Furthermore, the claw member 6 has a claw portion 601, which is arranged in a plurality of circumferential arrangements, and the claw members 6 are arranged in pairs.

[0033] In this embodiment, the chuck 6 is provided with several claw portions 601 arranged circumferentially on the outside of the chuck 6. The claw shape is changed according to different types of rock walls or soil walls. The chuck 6 is provided in several pairs. The claw portions 601 of the paired chuck 6 are opposite each other. Each pair of chuck 6 can fix the opening of the drill arm 2 at the part to be drilled. Under the action of multiple sets of multi-directional chuck 6, the first sliding cavity 201 outlet 202 of the drill arm 2 can be stably fixed, which can effectively prevent the first sliding cavity 201 outlet 202 of the drill arm 2 from sliding and vibrating along the rock wall direction during drilling.

[0034] Furthermore, the support member 11 includes a slide rod 1101 slidably disposed within the second slide cavity 1001, and a support leg 1102 hinged to the slide rod 1101.

[0035] In this embodiment, the support member 11 includes two parts: a slide rod 1101 and a support leg 1102. After sliding in the second sliding cavity 1001, the slide rod 1101 plays a role in buffering and driving the stop member 12 to slide. The support leg 1102 and the slide rod 1101 are hinged and have a relatively small rotation angle, which allows the support leg 1102 to be adaptively adjusted according to the different contact angles and positions with the rock wall, further improving the stability of the device.

[0036] Furthermore, it also includes a support foot 16 that is vertically slidably disposed on the support leg 1102. The support foot 16 has a first stop 1601 and a second stop 1602, which are located on both sides of the support leg 1102 respectively. One end of the third elastic member 17 acts on the first stop 1601 and the other end acts on the support leg 1102, providing a force to the support foot 16 away from the slide bar 1101.

[0037] In this embodiment, the support feet 16 are vertically slidably arranged. Under the action of the first stop 1601, the second stop 1602 and the third elastic member 17, the multiple support feet 16 can prevent the drilling deviation caused by the unevenness of the rock wall surface. After the support feet 16 are pressed against the rock wall, they can buffer the drilling process, further making the support effect of the support member 11 more stable.

[0038] Furthermore, there are several support feet 16, and the drill arms 2 are arranged in pairs on both sides of the vehicle body 1. The first rotating rod 8 and the second rotating rod 9 are also arranged in pairs on both sides of the drill arms 2.

[0039] In this embodiment, the drill arms 2 are arranged in pairs to drill holes in the rock walls on both sides simultaneously. The drill arms 2 on both sides can be controlled independently. The first drill rod and the second drill rod are both arranged in pairs on both sides of the drill arms 2. The support members 11 are also arranged in pairs to make the support more stable and increase the stability of the drilling process.

[0040] Furthermore, the support foot 16 has a support portion 1603, which is claw-shaped.

[0041] In this embodiment, the support part 1603 of the support foot 16 is set as a claw shape. When the support foot 16 is squeezed against the rock wall, the support part 1603 opens. When vibration occurs during drilling, the support foot 16 moves back slightly. At this time, the support part 1603 has a gripping effect, preventing the support foot 16 from retracting within a certain force range, thereby improving the stability of the drilling position.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
