Description

Technical Field

[0001] This invention relates to a pipeline rotation propulsion and dismantling and recycling device, belonging to the field of mining machinery technology. Background Technology

[0002] my country's coal storage environment is complex, and mining is primarily underground. Methane, a substance coexisting with coal, is also a clean energy source with a calorific value comparable to natural gas, and its abundant reserves offer promising application prospects. However, my country's coal seam geology is complex, with high methane content, strong adhesion, and poor permeability, making methane extraction difficult. To ensure the safety of methane tunnels and coal face uncovering operations, permeability enhancement measures must be implemented before operations to improve methane extraction efficiency. Commonly used permeability enhancement measures include hydraulic fracturing, deep-hole controlled pre-fracturing blasting, carbon dioxide phase change fracturing, and high-pressure air fracturing. Among these, carbon dioxide phase change fracturing requires a large number of metal pipe sections, which are threaded together to form a metal pipeline.

[0003] Currently, the transportation of metal pipes, the threaded connection of metal pipe sections into metal pipes, and the disassembly of metal pipes into metal pipe sections are mainly completed manually with the assistance of different equipment or tools. This has the disadvantages of high labor intensity, low construction efficiency, and large total area occupied by various equipment or tools. Summary of the Invention

[0013] The linkage assembly includes two fixed pulleys A and a rope A. One end of the rope A is connected to the bottom of the connecting plate, the middle part passes around the two fixed pulleys A, and the other end is connected to the bottom of the reservoir door.

[0014] An internal gear is provided at one end of the connecting plate near the pipe installation and disassembly mechanism.

[0024] 5. Through the transmission component, the rotational motion of the pneumatic motor B is converted into a composite motion of rotation and reciprocating linear movement of the transmission cylinder. The pipe gripper follows the transmission cylinder in a composite motion of rotation and reciprocating linear movement, thereby realizing automatic installation and removal of pipe sections.

[0025] 6. The power components of the equipment, pneumatic motor A, pneumatic motor B, and cylinder, are all driven by air, so they can be used with confidence in high-gas coal mines. Attached Figure Description

Detailed Implementation

[0036] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0037] like Figures 1 to 9As shown, the pipe rotation propulsion and dismantling / recycling equipment of the present invention includes two frames 1 and a pipe unloading mechanism 4. The two frames 1 are arranged side by side, and one end of the two frames 1 is connected by a pipe loading / unloading mechanism 5. A pipe conveying mechanism 2 is installed inside each of the two frames 1. A connector 3 is installed between the two frames 1, and the connector 3 is located between the pipe conveying mechanism 2 and the pipe loading / unloading mechanism 5. The pipe unloading mechanism 4 is installed on one of the frames 1 and is located above the connector 3. In use, the bottom of the frame 1 is provided with height-adjustable support feet 6. When the pipeline is rotated and advanced, connecting multiple pipe sections 7 into a single pipe, the pipe feeding mechanism 4 feeds the pipe sections 7 one by one. The pipe connector 3 catches the pipe sections 7 falling from the feeding mechanism 4. The pipeline assembly / disassembly mechanism 5 rotates forward and advances to catch the pipe section 7 on the connector 3, connecting it threadedly to the existing pipe section 7 on the pipeline conveying mechanism 2. The pipeline conveying mechanism 2 then conveys the connected pipeline forward a distance, completing one pipe section 7 assembly cycle. Repeating this process gradually connects multiple pipe sections 7 into a single pipe. When the pipeline is disassembled and retrieved, the pipeline conveying mechanism 2 conveys the pipeline backward a distance. The pipeline assembly / disassembly mechanism 5 reverses direction, advances forward to catch the last pipe section 7 on the pipeline, and rotates and moves the last pipe section 7 backward, thus disassembling the last joint 7, completing one pipe section 7 disassembly cycle. Repeating this process gradually disassembles the pipeline into multiple pipe sections 7. This equipment integrates functions such as automatic unloading of pipe sections, pipe assembly, transportation, and disassembly, which significantly reduces the labor intensity of workers, reduces the total footprint of the equipment, and improves the efficiency of pipeline construction.

[0038] The pipeline conveying mechanism 2 includes a pneumatic motor A, a driving sprocket 20, and a driven sprocket 23. The pneumatic motor A is mounted on the frame 1. The driving sprocket 20 is fitted onto the output shaft of the pneumatic motor A. The driven sprocket 23 is rotatably connected to the frame 1 and is connected to the driving sprocket 20 via a chain 21. A pipe-holding block 22 is mounted on the chain 21, and the pipe-holding block 22 has an arc-shaped slot A. In use, the pneumatic motor A can rotate in both directions. Two pipe-holding blocks 22 are mounted on each chain 21, and the pipe-holding blocks 22 on the chains 21 of the two pipeline conveying mechanisms 2 are symmetrically arranged. The pipe-holding blocks 22 on the two chains 21 cooperate to hold the pipeline, realizing the forward or backward conveying of the pipeline. The two ends of the arc-shaped slot A on the pipe-holding block 22 are chamfered to avoid interference when the pipe-holding block 22 first holds the pipeline and when it first detaches from the pipeline.

[0039] The pipe feeding mechanism 4 includes a storage container 40 and a storage container door 43. A stop block 41 is installed inside the storage container 40, and a pipe drop opening is provided between the stop block 41 and the inner wall of the storage container 40. An interval branch pipe component 42 is installed inside the storage container 40 at the pipe drop opening, and the interval branch pipe component 42 is located below the stop block 41. A pipe outlet is opened on the lower part of the storage container 40 near the pipe connector 3. A cavity 400 is provided at the bottom of the storage container 40. A part of the storage container door 43 is located inside the cavity 400 and is slidably connected to the cavity 400. It is also connected to the bottom plate of the cavity 400 through a spring B44. The other part of the storage container door 43 extends out of the cavity 400 and extends to the pipe outlet. In use, the top surface of the stop block 41 is tilted at a certain angle to the position where the pipe outlet is located. The outer diameter of the pipe section 7 is less than the width of the pipe outlet and less than twice the outer diameter of the pipe section 7, so that the pipe sections 7 located on the upper side of the stop block 41 fall downwards one by one into the lower part of the storage container 40. The pipe section 7 falling downwards from the pipe outlet is separated one by one by the interval branching component 42, so that the pipe feeding mechanism 4 can supply pipe sections 7 to the connecting pipe 3 one by one. The storage container door 43 can move upwards under the action of the spring B44 to block part or all of the outlet, preventing the pipe sections 7 in the storage container 40 from rolling outwards when feeding is not required.

[0040] The interval branch pipe component 42 includes a branch pipe assembly and a control assembly, and the control assembly can be snapped into the branch pipe assembly.

[0041] The pipe assembly includes a circular shaft A420, both ends of which are rotatably connected to the storage device 40. Two pipe discs 421 are fixedly mounted on the circular shaft A420, and multiple pipe rods 422 are evenly distributed on the outer circular surface of the pipe discs 421. A control disc 423 is fixedly mounted on the circular shaft A420 between the two pipe discs 421, and multiple slots are evenly distributed on the outer circular surface of the control disc 423.

[0042] The control assembly includes a control block A424, a control block B427, two fixed pulleys B426, and a rope B425. The upper part of the control block A424 is rotatably connected to the reservoir 40 via a rotating shaft A, and the upper part of the control block B427 is rotatably connected to the reservoir 40 via a rotating shaft B. A tapered locking block 428 is provided at the lower end of the control block B427 near the branch assembly. The tapered locking block 428 can be engaged in a slot on the control disc 423. The control block B427 is located between the two fixed pulleys B426 and above the control block A424. One end of the rope B425 is connected to the upper end of the control block A424, the middle part passes over the two fixed pulleys B426, and the other end is connected to the upper end of the control block B427. In use, the branch rods 422 on the two branch discs 421 are symmetrically arranged, and the branch rods 422 on the two branch discs 421 separate the pipe sections 7 one by one. The number of slots on the control panel 423 is the same as the number of branch rods 422 on the branch panel 421, both being four, and the positions of the slots are directly opposite the positions of the branch rods 422. For example... Figure 2 and Figure 4 As shown, when there are pipe sections 7 on both the left and right sides of control block A424, that is, when control block A424 is clamped by the pipe sections 7 on its left and right sides, the conical locking block 428 on control block B427 just gets into one of the slots on control disk 423, and the round shaft A420 remains fixed. When the pipe section 7 on the left side of control block A424 falls out of the outlet, the pipe section 7 on the right side of control block A424 rolls towards the outlet, and during the rolling process, it pushes control block A424 to rotate clockwise around axis A by a certain angle. At the same time, control block A424 pulls control block B427 to rotate clockwise around axis B by rope B425 by a certain angle. When the pipe section 7 on the right side of control block A424 is just about to roll to the left side of control block A424, the conical locking block 428 disengages from the slot. After rolling to the left side of control block A424, control block A424 rotates counterclockwise around axis A under its own weight to reset. Control block B427 also rotates counterclockwise around axis B under its own weight. The conical locking block 428 contacts the outer circular surface of control disk 423. At the same time, under the gravity of the upper pipe section 7, the branch pipe rod 422 drives the circular shaft A420 to rotate clockwise. One pipe section 7 falls from the branch pipe rod 422 to the lower part of the reservoir 40 and rolls to the left. When the circular shaft A420 rotates 90 degrees clockwise, the conical locking block 428 just fits into another slot on the control disk 423. The circular shaft A420 is fixed. Then the newly fallen pipe section 7 continues to roll to the left, cooperating with the pipe section 7 on the left side of control block A424 to clamp control block A424 and maintain its position.

[0043] The connector 3 includes a base plate 32 and a connector plate 30. The connector plate 30 is located directly above the base plate 32 and is connected to the base plate 32 by a spring A33. The top of the connector plate 30 has an arc-shaped slot B, and the bottom is connected to the bottom of the reservoir door 43 by two linkage components.

[0044] The linkage component includes two fixed pulleys A34 and a rope A35. One end of the rope A35 is connected to the bottom of the connecting plate 30, the middle part passes around the two fixed pulleys A34, and the other end is connected to the bottom of the reservoir door 43. When a pipe section 7 falls from the pipe feeding mechanism 4 onto the connecting plate 30, the pipe section 7 presses the connecting plate 30 downwards, compressing the spring A33 and relaxing the rope A35. At the same time, the spring B44 extends, pushing the storage tank door 43 upwards to block the outlet until the rope A35 is taut. This prevents the pipe feeding mechanism 4 from supplying another pipe section 7 to the connecting device 3, ensuring that there is at most one pipe section 7 on the connecting device 3. When the pipe section 7 on the connecting plate 30 is removed, the spring A33 extends, pushing the connecting plate 30 upwards. At the same time, the rope A35 pulls the storage tank door 43 downwards against the action of the spring B44, opening the outlet. This allows the pipe feeding mechanism 4 to supply another pipe section 7 to the connecting device 3, achieving linkage control between the connecting device 3 and the storage tank door 43.

[0045] An internal gear 31 is machined on one end of the connecting plate 30 near the pipe assembly / disassembly mechanism 5. An angle adjustment rod 55 is movably mounted on the pipe assembly / disassembly mechanism 5, and a locking screw is threaded onto the mechanism at a position corresponding to the angle adjustment rod 55. A gear C56 is mounted on one end of the angle adjustment rod 55 near the connecting plate 30, and the shape and size of the gear C56 match the internal gear 31. Before disassembling the pipe, push the angle adjustment rod 55 to engage the gear C56 with the internal gear 31, then rotate the angle adjustment rod 55 to tilt the connecting plate 30, and then tighten the locking screw to fix the angle adjustment rod 55, facilitating the rolling and falling of the pipe section 7 removed from the pipe along the connecting plate 30.

[0046] The pipe installation and disassembly mechanism 5 includes a housing 50, a drive assembly 51, a transmission assembly 52, and a pipe clamp 53. The drive assembly 51 is mounted on the housing 50, the transmission assembly 52 is mounted on the housing 50 and passes through the housing 50, and the transmission assembly 52 is connected to the drive assembly 51 in a transmission manner. The pipe clamp 53 is mounted on the transmission assembly 52 at one end near the pipe connector 3.

[0047] The drive assembly 51 includes a pneumatic motor B510 and a gear A511 mounted on the pneumatic motor B510;

[0048] The transmission assembly 52 includes a support 521, a support shaft 520, a gear B522, and a transmission cylinder 525. The support 521 is mounted on the housing 50. One end of the support shaft 520 is fixedly connected to the side wall of the housing 50 and the support 521. One end of the gear B522 is fixedly provided with a bushing 523. The gear B522 and the bushing 523 are rotatably mounted on the support shaft 520. The transmission cylinder 525 is a hollow cylinder. One end of the transmission cylinder 525 has a through hole, and a key 525 is used to pass through it. 24 is slidably connected to the bushing 523, and a groove is provided on the inner wall of the transmission cylinder 525 along the circumferential direction. One end of the support shaft 520 is fixedly installed with a bevel gear B529. A round shaft B527 is provided on the bushing 523 along the radial direction. A bevel gear A526 is rotatably fitted on the round shaft B527, and the bevel gear A526 meshes with the bevel gear B529. A transmission rod 528 is eccentrically provided on the bevel gear A526, and part of the transmission rod 528 extends into the groove on the inner wall of the transmission cylinder 525. In use, the pneumatic motor B510 can rotate in both directions. The pneumatic motor B510 provides power, which drives the gear B522 and the bushing 523 to rotate through the gear A511. The bushing 523 drives the transmission cylinder 525 to rotate through the key 524. At the same time, since the bevel gear A526 meshes with the bevel gear B529, the bevel gear A526 will rotate around the circular shaft B527 when it follows the rotation of the bushing 523. During the rotation, the bevel gear A526 drives the transmission cylinder 525 to make reciprocating linear motion along the axial direction of the bushing 523 through the transmission rod 528. In other words, through the transmission assembly 52, the rotational motion of the pneumatic motor B510 is transformed into a compound motion of rotation and reciprocating linear motion of the transmission cylinder 525.

[0049] The pipe gripper 53 includes a base 530, a cylinder 538, a spring C537, and a control rod 532. A sliding hole is coaxially formed on the base 530. The cylinder 538 is located inside the base 530 and partially extends into the sliding hole. The spring C537 is located inside the sliding hole, with one end of the spring C537 abutting against the outer shell of the cylinder 538. Two pipe grippers are symmetrically arranged at one end of the base 530. Each pipe gripper includes a support block 531 and a connecting block B534. One end of the support block 531 is fixed to the base 530. The connection is fixed. One end of the connecting block B534 is rotatably connected to the end of the support block 531 away from the base 530 via the connecting block A533. The other end is fixedly equipped with a pipe-holding block B535, which has an arc-shaped groove C. The middle of the connecting block B534 in the two pipe-holding claws is rotatably connected by two connecting plates 536. One end of the control rod 532 is connected to the two connecting plates 536, and the other end extends into the sliding hole on the base 530 and abuts against one end of the spring C537. In use, the base 530 is fixedly installed on the transmission cylinder 525 near the end of the pipe connector 3 and follows the transmission cylinder 525 to perform a compound motion of rotation and reciprocating linear movement. The control rod 532 is slidably connected to the sliding hole on the base 530. When the two connecting plates 536 are subjected to a thrust along the axial direction of the control rod 532 and pointing towards the base 530, the control rod 532 moves closer to the base 530, the spring C537 is compressed, and the pipe-holding blocks B535 in the two pipe-holding claws move closer to each other to hold the pipe section 7. When the thrust disappears, the spring C537 extends, pushing the control rod 532 away from the base 530, and the pipe-holding blocks B535 in the two pipe-holding claws move away from each other to release the pipe section 7.

[0050] Specifically, one end of pipe section 7 is machined with an external thread, and the other end is machined with an internal thread, with the external thread matching the internal thread.

[0051] The working principle of the pipeline rotation propulsion, disassembly, and recovery equipment described in this invention is as follows:

[0052] The working principle of the equipment, which connects multiple pipe sections 7 into a pipeline and transports them forward, is as follows:

[0053] 1. Pipe feeding mechanism and connecting device for connecting sections: such as Figures 2 to 4As shown, multiple pipe sections 7 are stacked in the storage container 40, with two pipe sections 7 rolling to the lower part of the storage container 40 and clamping the control block A424. In the initial state, there are no pipe sections 7 on the connecting plate 30. The connecting plate 30 pulls the storage container door 43 downward through the rope A35, overcoming the action of the spring B44, thus opening the outlet. After the outlet opens, the pipe section 7 on the left side of the control block A424 falls out through the outlet and onto the connecting plate 30. The pipe section 7 presses the connecting plate 30 downward, compressing the spring A33 and slackening the rope A35. At the same time, the spring B44 extends and pushes the storage container door 43 upward to block the outlet until the rope A35 is taut, thereby preventing the pipe feeding mechanism 4 from supplying another pipe section 7 to the connecting container 3, ensuring that there is at most one pipe section 7 on the connecting container 3.

[0054] Simultaneously, the pipe section 7 on the right side of control block A424 rolls towards the outlet, pushing control block A424 to rotate clockwise around axis A by a certain angle during the rolling process. At the same time, control block A424 pulls control block B427 to rotate clockwise around axis B by rope B425. When the pipe section 7 on the right side of control block A424 is about to roll to the left side of control block A424, the conical locking block 428 disengages from the slot. After the pipe section 7 on the right side of control block A424 rolls to the left side of control block A424, control block A424, under its own weight, rotates counterclockwise around axis A to reset. Control block B427, under its own weight, rotates counterclockwise around axis A to reset. When shaft B rotates counterclockwise, the conical locking block 428 contacts the outer circular surface of the control panel 423. At the same time, under the gravity of the upper pipe section 7, the branch pipe rod 422 drives the circular shaft A420 to rotate clockwise. One pipe section 7 falls from the branch pipe rod 422 to the lower part of the reservoir 40 and rolls to the left. When the circular shaft A420 rotates 90 degrees clockwise, the conical locking block 428 just gets into another slot on the control panel 423. The circular shaft A420 is fixed. Then the newly fallen pipe section 7 continues to roll to the left, cooperating with the pipe section 7 on the left side of the control block A424 to clamp the control block A424 and maintain its position.

[0055] When the pipe section 7 on the connecting plate 30 is removed, the spring A33 extends and pushes the connecting plate 30 upward, while the cable A35 pulls the storage tank door 43 downward against the action of the spring B44, thus opening the outlet. By repeating the above process, the pipe feeding mechanism 4 can automatically supply the pipe sections 7 one by one to the connecting device 3, realizing automatic feeding of the pipe sections 7.

[0056] 2. Pipe section assembly and transportation: such as Figures 5 to 8As shown, after the connecting plate 30 receives the first pipe section 7, the pneumatic motor B510 rotates forward and drives the pipe gripper 53 to perform a combined rotational and reciprocating linear motion through the transmission assembly 52. ​​During the forward movement, the pipe gripper 53 pushes the front end of the first pipe section 7 between the two pipe conveying mechanisms 2. Then the pipe gripper 53 moves backward to reset, and the two pipe conveying mechanisms 2 are activated. The pipe gripping blocks 22 in the two pipe conveying mechanisms 2 cooperate to grip the first pipe section 7 and convey it forward a certain distance.

[0057] Then, the second pipe section 7 falls onto the connecting plate 30, the pneumatic motor B510 rotates forward, and drives gear B522 and bushing 523 to rotate via gear A511. Bushing 523 drives transmission cylinder 525 to rotate clockwise via key 524. At the same time, since bevel gear A526 meshes with bevel gear B529, bevel gear A526 rotates around shaft B527 as it follows the rotation of bushing 523. During the rotation, bevel gear A526 is driven by transmission rod 528. The transmission cylinder 525 reciprocates linearly along the axial direction of the bushing 523. The transmission cylinder 525 drives the pipe gripper 53 in a combined clockwise rotation and reciprocating linear motion. When the pipe gripper 53 moves forward, it pushes the second pipe section 7 forward. When the front end of the second pipe section 7 abuts against the rear end of the first pipe section 7, the first pipe section 7, through the reaction force of the second pipe section 7, exerts a force on the two connecting plates 536 in the pipe gripper 53. The control rod 532 moves closer to the base 530. As the pipe moves in the direction of movement, spring C537 is compressed, and the pipe-holding blocks B535 in the two pipe-holding claws move closer to each other to hold the second pipe section 7. The pipe gripper 53 drives the second pipe section 7 to move forward and rotate clockwise, and the second pipe section 7 and the first pipe section 7 begin to be threadedly connected to form a pipe. After the second pipe section 7 and the first pipe section 7 are threadedly connected, the transmission cylinder 525 drives the pipe gripper 53 to start moving backward. Since the friction between the pipe-holding block 22 and the pipe is greater than the friction between the pipe-holding block B535 and the pipe, the pipe-holding block B535 slips relative to the pipe. The pipe gripper 53 follows the transmission cylinder 525 and moves backward normally. After the pipe gripper 53 moves a certain distance relative to the second pipe section 7, the force exerted by the second pipe section 7 on the two connecting plates 536 in the pipe gripper 53 disappears, spring C537 extends and pushes the control rod 532 forward, and the pipe-holding blocks B535 in the two pipe-holding claws move away from each other to release the second pipe section 7. Next, the two pipeline conveying mechanisms 2 operate, causing the pipeline formed by connecting the second pipe section 7 and the first pipe section 7 to move forward a certain distance; repeating the above process, multiple pipe sections 7 can be connected into a pipeline and the pipeline can be conveyed forward.

[0058] II. The working principle of the equipment that transports the pipeline backward and breaks it down into multiple pipe sections is as follows:

[0059] 1. Preliminary preparation: Separate rope A35 from pipe storage door 43 and remove pipe feeding mechanism 4 from frame 1. Then place pipe feeding mechanism 4 on one side of connector 3 to collect disassembled pipe sections 7. Push tilt adjustment rod 55 to engage gear C56 with internal gear 31. Then rotate tilt adjustment rod 55 to tilt connector plate 30 toward the side where pipe feeding mechanism 4 is placed. Then tighten locking screw to fix tilt adjustment rod 55, so that pipe sections 7 disassembled from the pipe can roll down connector plate 30 and fall into pipe feeding mechanism 4.

[0060] 2. Pipe Disassembly and Recycling: The two pipe conveying mechanisms 2 activate, moving the pipe backward a short distance. The pneumatic motor B510 reverses, driving the pipe gripper 53 to perform a combined counter-clockwise rotation and reciprocating linear motion. When the pipe gripper 53 is about to reach its maximum stroke, the two connecting plates 536 in the pipe gripper 53 contact the rear end of the pipe and push the pipe forward. The pipe's reaction force acts on the two connecting plates 536, causing the gripping blocks B535 in the two gripping claws to move closer together and grip the pipe section 7 at the rear end of the pipe. Then, the pipe gripper 53 drives the pipe section 7 to rotate counter-clockwise and move backward, separating it from the second-to-last pipe section 7 on the pipe. Then, the cylinder 538 activates, its piston rod passing through the spring C537 and pushing the control rod 532 outward, causing the gripping blocks B535 in the two gripping claws to move further apart, releasing the pipe section 7. The pipe section 7 rolls along the connecting plate 30 and falls into the pipe unloading mechanism 4. Repeating the above process achieves pipe disassembly and recycling.
