Description

Technical Field

[0001] This utility model relates to the field of rock drilling construction technology, specifically a rock drilling rod connection and unloading device. Background Technology

[0002] As a major support method for underground engineering and rock slopes, anchor bolts are widely used in highway and railway tunnels and mining roadways. With the development of anchor bolt support, the forms, types and specifications of anchor bolts are becoming more and more diverse. In order to obtain better support effects, the length requirements of anchor bolts are also increasing, and anchor bolt holes need to be drilled deeper.

[0003] Currently, most drilling equipment on the market uses drill rods with a fixed drilling depth. When the required drilling depth exceeds the length of the drill rod, multiple drill rods need to be connected for drilling. This involves manually inserting the anchor rod into the jointing position and then using a rock drill to complete the jointing action. This not only results in low overall construction efficiency but also poses certain safety hazards. Furthermore, in current jointing operations, although the position of the drill rod on the advance beam is fixed, the position of the drill rod already driven into the hole may deviate, making it difficult to quickly connect two drill rods, leading to low overall construction efficiency.

[0026] like Figure 1 , Figure 2 The diagram shows a drilling rod connection and disconnection device disclosed in this embodiment. It mainly includes a propulsion beam 1 and a rock drill 2, a gripper 3, and a clamping device 4 mounted on the propulsion beam 1. The rock drill 2 is slidably connected to the propulsion beam 1 and is used to drive the drill rod into the borehole or to remove the drill rod from the borehole. There is at least one gripper 3 located on the side of the propulsion beam 1, and when there are two or more grippers 3, all grippers 3 are located on the same side of the propulsion beam 1. The gripper 3 has a first jaw 301 that can tilt and clamp or release the drill rod, used to grip the drill rod and feed it into a designated position on the propulsion beam 1, or to remove the drill rod from the designated position. The clamping device 4 is located at the front end of the propulsion beam 1 (i.e., the end of the propulsion beam 1 facing the borehole), and the clamping device 4 has a second jaw 401 that can clamp or release the drill rod, used to clamp the drill rod during connection or disconnection.

[0027] In this embodiment, the drill rod joining and unloading device uses a gripper 3 on the side of the push beam 1. The gripper 3's first jaw 301 can be tilted up and down to move the drill rod gripped in the first jaw 301 to a designated position, or to move the drill rod away from the designated position, thus replacing manual joining. This not only improves construction efficiency but also effectively ensures construction safety. Furthermore, the clamp 4 acts as a clamp during joining and unloading. When joining, the clamp 4 accurately positions the drill rod inside the borehole, aligning it with the drill rod to be driven into the push beam 1, further improving construction efficiency. When unloading, the clamp 4 holds and fixes the previous drill rod, facilitating separation of the two drill rods.

[0028] In practical implementation, the propulsion beam 1 is also equipped with a central drill bit stabilizer 5, which is used to stabilize the drill rod during drilling or retraction. (Reference) Figure 3The middle support rod 5 is slidably connected to the push beam 1. The middle support rod 5 is provided with a support rod groove 501 that coincides with the designated work position. The top of the middle support rod 5 is provided with an opening 502 that communicates with the support rod groove 501 on the side facing the gripper 3, so that the drill rod can be sent into the support rod groove 501 when the first jaw 301 on the gripper 3 is tilted down, or the drill rod can be taken away from the support rod groove 501 when the gripper 3 is tilted up.

[0029] In the specific implementation process, the propulsion beam 1 is also equipped with an end support device 6. (Reference) Figure 4 The end support 6 is fixedly connected to the front end of the clamp 4 (i.e. the end of the clamp 4 facing the drill hole). The end support 6 is provided with a flared mouth 601, and the flared end of the flared mouth 601 faces the rock drill 2. The drill rod passes through the flared mouth 601 when drilling or withdrawing, so that the end support 6 plays the role of stabilizing the drill rod and guiding it when drilling or withdrawing.

[0030] refer to Figure 5 , Figure 6 The gripper 3 includes a base 302, a flipping jaw 303, and an opening and closing jaw 304. The first end of the flipping jaw 303 is hinged to the base 302, and the first end of the opening and closing jaw 304 is hinged to the flipping jaw 303. The second end of the flipping jaw 303 and the second end of the opening and closing jaw 304 form a first jaw 301, that is, the clamping and loosening of the drill rod 5 is realized by opening and closing the first jaw 301.

[0031] The base 302 includes two spaced-apart first side plates 3021, with a stiffening plate 3022 welded between the two first side plates 3021. A connecting plate 3023 is fixedly connected to the first end of each of the two first side plates 3021, and the connecting plate 3023 has multiple connecting holes 3024. The connecting plate 3023 and the connecting holes 3024 together form a connecting structure, allowing the base 302 to be fixed to the side of the push beam 1 using bolts.

[0032] The flipping gripper 303 includes two spaced-apart second side plates 3031 and a connecting cylinder 3032 fixedly connected to the bottom of the first ends of the two second side plates 3031. The second ends of the two second side plates 3031 together form the second end of the flipping gripper 303. The connecting cylinder 3032 is hinged to the two first side plates 3021 by a first pin, and the connecting cylinder 3032 is located between the two first side plates 3021. That is, the flipping gripper 303 is directly hinged to the base 302, which makes the gripping device structure more compact and reduces costs.

[0033] In specific implementation, the gripper 3 also includes a tilting drive unit 305. The first end of the tilting drive unit 305 is hinged to the outer wall of a first side plate 3021 near its second end via a second pin. The second end of the tilting drive unit 305 is hinged to the outer wall of a second side plate 3031 on the same side near its second end via a third pin. The tilting drive unit 305 has a telescopic stroke. As the tilting drive unit 305 extends and retracts, it drives the tilting jaw 303 to tilt on the base 302, thereby moving the drill rod gripped on the first jaw 301 into the designated position or moving the drill rod on the first jaw 301 away from the designated position. The tilting drive unit 305 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc.

[0034] It is worth noting that in specific applications, the tilting gripper 303 is not limited to being driven by a tilting drive unit 305 with a telescopic stroke. Alternatively, the first pin can be fixedly connected to the connecting cylinder 3032, and after the first pin is rotatedly engaged with the first side plate 3021, the first pin can be driven to rotate by a servo motor, hydraulic motor, or other power components, thereby causing the tilting gripper 303 to tilt.

[0035] In a preferred embodiment, a limiting member 306 is provided on the base 302, and the limiting member 306 is located on the downward path of the flipping jaw 303, thereby limiting the downward position of the flipping jaw 303, so that the drill rod gripped on the first jaw 301 can be accurately placed on the designated work position. More preferably, the height of the limiting member 306 on the base 302 is adjustable. For example, a bolt or screw connected to the base 302 is used as the limiting member 306, so that the height of the limiting member 306 can be adjusted with the depth of the threaded connection, thereby allowing the gripper 3 to adapt to the different push beams 1 at each designated work position, and also compensating for the assembly error of the gripper 3 on the push beam 1.

[0036] The opening and closing gripper 304 includes two L-shaped third side plates, which are located between two second side plates 3031. The first ends of the two third side plates are hinged to the two second side plates 3031 via a fourth pin, and the second ends of the two third side plates together form the second end of the opening and closing gripper 304. Optionally, the fourth pin and the third pin can be the same shaft or different shafts.

[0037] In specific implementation, the gripper 3 also includes an opening and closing drive unit 307. The first end of the opening and closing drive unit 307 is hinged to the first ends of the two second side plates 3031 via a fifth pin, and the second end of the opening and closing drive unit 307 is hinged to the L-shaped bottom corners of the two third side plates via a sixth pin. The opening and closing drive unit 307 has a telescopic stroke. As the opening and closing drive unit 307 extends and retracts, it can drive the opening and closing gripper 304 to rotate around the fourth pin on the flipping gripper 303, thereby realizing the opening and closing action of the first jaw 301. The opening and closing drive unit 307 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc.

[0038] It is worth noting that in specific applications, the opening and closing gripper 304 is not limited to being driven to rotate by the opening and closing drive unit 307 with a telescopic stroke. Alternatively, the fourth pin can be fixedly connected to the two third side plates, and the fourth pin can be rotated in conjunction with the two second side plates 3031. Then, a servo motor, hydraulic motor, or other power components can be used to drive the fourth pin to rotate, thereby driving the opening and closing gripper 304 to rotate.

[0039] In the specific implementation process, a first clamping block 308 is fixedly clamped between the second ends of the two second side plates 3031, and a second clamping block 309 is fixedly clamped between the second ends of the two third side plates. The first jaw 301 is located between the first clamping block 308 and the second clamping block 309. The first clamping block 308 is fixedly connected to the two second side plates 3031 by bolts or welding. Similarly, the second clamping block 309 is fixedly connected to the two third side plates by bolts or welding. Preferably, both the side of the first clamping block 308 facing the second clamping block 309 and the side of the second clamping block 309 facing the first clamping block 308 are provided with arc-shaped grooves, so that the first clamping block 308 and the second clamping block 309 can play a guiding role when gripping the drill rod, improving the clamping stability of the drill rod.

[0040] refer to Figure 7 , Figure 8The clamp 4 includes a frame 402, a first clamp 403, and a second clamp 404. The frame 402 is fixedly connected to the front end of the push beam 1 by bolts or other fasteners. The middle parts of the first clamp 403 and the second clamp 404 are hinged to the frame 402. A clamping drive unit 405 is hinged between the first end of the first clamp 403 and the first end of the second clamp 404, and the clamping drive unit 405 has a telescopic stroke. The second ends of the first clamp 403 and the second ends of the second clamp 404 form a second jaw 401. When the clamping drive unit 405 extends, it can move the first ends of the first clamp 403 and the second clamp 404 away from each other, and then move the second ends of the first clamp 403 and the second clamp 404 closer together, thereby driving the second jaw 401 to gradually close, thus realizing the clamping action of the drill pipe. The shortening of the clamping drive unit 405 allows the first end of the first clamp 403 to approach the first end of the second clamp 404, thereby causing the second end of the first clamp 403 to move away from the second end of the second clamp 404, which in turn drives the second jaw 401 to gradually open, thereby realizing the release action of the drill rod.

[0041] In this embodiment, the frame 402 includes a base plate and a front side plate and a rear side plate spaced apart on the base plate. The top and / or middle of the front side plate and the rear side plate can be connected by a connecting plate. The outer wall of the front side plate is fixedly connected to the front end of the push beam 1, and the end support rod 6 is fixedly connected to the outer wall of the rear side plate. The first clamp 403 is rotatably connected between the front side plate and the rear side plate by a seventh pin, and the second clamp 404 is hinged between the front side plate and the rear side plate by an eighth pin. In specific implementation, the first clamp 403 can be fixedly engaged with the seventh pin, and then the seventh pin can be rotatably engaged with the front side plate and the rear side plate; or the first clamp 403 can be rotatably engaged with the seventh pin, and then the seventh pin can be fixedly engaged with the front side plate and the rear side plate. Similarly, the second clamp 404 can be fixedly fitted to the eighth pin, and then the eighth pin can be rotatably fitted to the front and rear side plates; alternatively, the second clamp 404 can be rotatably fitted to the eighth pin, and then the eighth pin can be fixedly fitted to the front and rear side plates. The fixed fit can be achieved through interference fit, key connection, welding, bolt connection, etc., while the rotatable fit can be achieved through clearance fit, bearing connection, etc.

[0042] In a preferred embodiment, the clamp 4 further includes a synchronizing pin 406. The first clamp 403 has a first oblong groove, the second clamp 404 has a second oblong groove, and the front and / or rear side plates have vertical strip grooves. The synchronizing pin 406 passes through the first oblong groove, the second oblong groove, and the strip groove, thus enabling synchronized movement of the first clamp 403 and the second clamp 404. For example, when the first clamp 403 rotates, the synchronizing pin 406 slides along the first oblong groove. Due to the lateral limitation of the strip groove, the synchronizing pin 406 can only move vertically, thereby forcing the second oblong groove on the second clamp 404 to follow the movement of the synchronizing pin 406, thus causing the second clamp 404 to move synchronously with the first clamp 403.

[0043] In this embodiment, both the front and rear side plates are provided with strip grooves, and the two ends of the synchronizing pin 406 are provided with bending structures or pins to prevent the synchronizing pin 406 from slipping off. It is worth noting that in specific applications, the synchronizing pin 406 is not limited to having bending structures or pins at both ends; baffles 409 can also be provided on the outer walls of the front and rear side plates, covering the strip grooves, which can also prevent the synchronizing pin 406 from slipping off. Figure 9 As shown. Preferably, the inner wall of the baffle 409 is provided with a recessed groove, which can completely cover the strip groove. The end of the synchronizing pin 8 passes through the strip groove and is embedded in the recessed groove. By setting the recessed groove, the length of the synchronizing pin 406 is effectively increased, preventing the synchronizing pin 406 from bending and falling off the strip groove.

[0044] In this embodiment, the clamping drive unit 405 is a hydraulic cylinder or a pneumatic cylinder. Since both hydraulic and pneumatic cylinders require corresponding oil and air supply lines, this embodiment preferably provides a protective cover 407 on one side of the frame 402 corresponding to the oil or air pipes on the clamping drive unit 405 to protect the oil or air pipes of the clamping drive unit 405. Of course, in practical applications, a protective cover can also be provided on the other side of the frame 402.

[0045] In practical implementation, both the second end of the first clamp 403 and the second end of the second clamp 404 are provided with clamping blocks 408, and the second jaw 401 is located between the two clamping blocks 408. (Reference) Figure 10 The clamping block 408 includes a connecting part 4081 and a clamping part 4082 fixedly connected together. The connecting part 4081 is fixedly connected to the first clamp 403 or the second clamp 404 by bolts or welding. The clamping part 4082 is crescent-shaped, and the second jaw 401 is located between the two clamping parts 4082. By setting the clamping part 4082 to a crescent shape, the drill rod can be quickly guided into the second jaw 401 when it is opened. Preferably, the clamping part 4082 is provided with a serrated groove 4083 to increase the clamping force when clamping the drill rod and improve the stability of the clamping device.

[0046] In this embodiment, the rod connection process of the rod connection and unloading device is as follows: Before construction, connect the first drill rod 7 to the rock drill 2 and clamp the second drill rod 8 between the two grippers 3. After the rock drill 2 drives the first drill rod 7 into the surrounding rock, the clamp 4 clamps the first drill rod 7, then the rock drill 2 is disconnected from the first drill rod 7, and the rock drill 2 is retracted to the end of the push beam 1. After using the two grippers 3 to rotate the second drill rod 8 to the designated position, the rock drill 2 moves forward again until it connects with the second drill rod 8, then the grippers 3 are released and rotated back to the initial position; The rock drill 2 then continues to advance, driving the second drill rod 8 forward. After connecting the second drill rod 8 with the first drill rod 7, drilling continues.

[0047] In this embodiment, the rod unloading process of the rod connecting and unloading device is as follows: After drilling is completed, the rock drill 2 drives the second drill rod 8 and the first drill rod 7 to retract as a whole to the end of the propulsion beam 1. Then, after the clamp 4 clamps the first drill rod 7, the rock drill 2 continues to retract, disengaging the second drill rod 8 from the first drill rod 7; Subsequently, the two grippers 3 flipped to the designated position and gripped the second drill rod 8. Then, the rock drill 2 continued to retreat, disengaging the rock drill 2 from the second drill rod 8. After the two grippers 3 flip and drive the second drill rod 8 back to the initial position, the rock drill 2 moves forward and connects with the first drill rod 7. Then, the gripper 4 is released, so that the rock drill 2 drives the first drill rod 7 to continue to retreat to the end of the push beam 1.
