Description

Technical Field

[0001] The present invention relates to the technical field of oil drilling, and particularly to an adjustable chain-type hydraulic drive high-torque up-and-down make-up and break-out detection device. Background Art

[0002] In oil drilling, a large number of pipelines are used, and these pipelines often need to be disassembled or installed. Pipes in some special positions also need to be subjected to rotation detection, and pipe make-up and break-out is a key operation. When it is necessary to disassemble a pipe string, first, a suitable tool, such as a hydraulic tong, is used. The jaws of the tong are clamped on the pipe joint, and by controlling the hydraulic system to apply a reverse torque, the connected threads are gradually loosened. There are also cases where the threading of pipe tools and tool joints is tightened and loosened manually.

[0003] A pipe disassembly device and its use method with the publication number CN114658375A include: a fixing frame for installing on a drill pipe; a sliding member slidably arranged on the fixing frame and for installing on an adjacent drill pipe; and a handle installed on the fixing frame and drivingly connected to the sliding member. By rotating the handle, the sliding member is driven to move along the fixing frame, so as to drive two drill pipes to move away from each other, so that the two drill pipes are separated. The present invention effectively solves the problem that it is relatively difficult to disassemble drill pipes. By separating the two connected drill pipes through this disassembly device, manual disassembly of drill pipes can be avoided, which saves time and effort, and avoids damage to equipment, reduces potential safety hazards, and can be applied to narrow construction environments.

[0004] The above-mentioned prior arts all have the following several problems: 1) It is not convenient to make up and break out pipes with different thicknesses, and it is difficult to make up the connection. The central axes of the two pipe tools are not concentric; 2) It is also difficult to ensure whether the threading is in place; 3) The working efficiency is low and the safety and reliability are low.

[0005] Therefore, an adjustable chain-type hydraulic drive high-torque up-and-down make-up and break-out detection device is needed. Summary of the Invention

[0006] In order to solve all or part of the above problems, the purpose of the present invention is to provide an adjustable chain-type hydraulic drive high-torque up-and-down make-up and break-out detection device, so as to solve the problems of inconvenient operation for pipes with different diameters, difficult to ensure whether the threading is in place, low working efficiency, and low safety and reliability.

[0007] To achieve the above object, the present invention provides the following technical solution: An adjustable chain-type hydraulic drive high-torque up and down pipe coupling detection device, including a hydraulic power control console and a hydraulic actuator connected and communicated with the hydraulic power control console. A base is provided on the lower side of the hydraulic actuator. The hydraulic actuator is installed on one side of the upper end of the base. A support slide is installed on the other side of the upper end of the base. A friction back-up tong and a saddle are installed on the upper end of the support slide. A friction main tong is provided at the driving end of the hydraulic actuator. A pipe is placed in the middle of the upper ends of the friction back-up tong, the friction main tong and the saddle; The hydraulic actuator includes a telescopic cylinder and a lifting cylinder. The lower ends of the telescopic cylinder and the lifting cylinder are both arranged on the support on the upper end of the base; The friction main tong includes a tong handle and a tong jaw installed at one end of the tong handle. The other end of the tong handle is movably connected to the upper end of the telescopic cylinder. The rotation of the tong handle drives the tong jaw to rotate synchronously; A bending fastener that can be freely bent to match pipes of different diameters is arranged on the inner side of one end of the tong jaw. The free end of the bending fastener passes through the other end of the tong jaw; The free end of the bending fastener on the tong handle is restricted by a locking component arranged on the tong handle. And when the telescopic cylinder pushes up to drive the tong handle to reverse, the locking component restricts the bending fastener from moving, and rotates the pipe. When the telescopic cylinder drives the tong handle to rotate forward, the locking component does not restrict the bending fastener from moving, and the bending fastener can move slightly around the pipe. That is, when the tong handle rotates forward, it will not drive the pipe to rotate.

[0008] Further, a main tong lock pin and an adjusting locking piece are arranged on the inner side of one end of the tong handle. When the free end of the bending fastener passes through the tong handle, it needs to pass between the main tong lock pin and the adjusting locking piece in the open state. The gap between the main tong lock pin and the adjusting locking piece in the locked state is smaller than the bending part on the bending fastener.

[0009] Further, the adjusting locking piece includes a locking main block and a locking handle. The locking main block is fixedly connected to the locking handle. A convex part is arranged at the upper end of one side of the locking main block. And a smooth part is arranged at the lower end of the locking main block on the same side as the convex part. And the locking main block can rotate on the central pin fixedly arranged on the tong handle. The central pin is fixedly connected to the tong handle.

[0010] Further, an adjusting component is arranged at the connection between the locking handle and the locking main block. By rotating the adjusting component, the adjusting component is buckled on the retaining bar arranged on the inner side of the tong handle to control the locking of the locking main block. Further, the locking main block controls the locking or unlocking of the bending fastener.

[0011] Further, the adjusting component includes an adjusting claw and an elastic member installed at the upper end of the adjusting claw. The upper end of the adjusting claw is rotatably connected to the locking handle. And the elastic member is sleeved on the outer side of the upper end of the adjusting claw. One end of the elastic member is fixedly connected to the adjusting claw and the other end is fixedly connected to the locking handle.

[0012] Further, one side of the adjusting claw is provided with a lower opening and an upper opening, both of which are adapted to the retaining rod. When the lower opening is adapted to the retaining rod, the bending fastener is in a locked state at this time. When the upper opening is adapted to the retaining rod, the bending fastener is in an unlocked state at this time.

[0013] Further, when the free end of the bending fastener passes through the pliers handle, it needs to pass between the main pliers lock pin and the center pin arranged on the inner side of the pliers handle. Both the main pliers lock pin and the center pin are movably connected to the pliers handle. A lock pin is threadedly installed at the middle position of the upper end of the pliers handle. The middle part of the lock pin is inserted into the bent part of the bending fastener. The diameter of the lock pin is smaller than the length of the movable hole of the bending fastener.

[0014] Further, the bending fastener is a bendable chain.

[0015] Further, the bending fastener is a component composed of a connecting part, an elastic part and a free end part. One end of the elastic part is fixedly connected to the connecting part and the other end is fixedly connected to the free end part. Both the free end part and the connecting part are chains, and the elastic part is rubber and is arranged in a hollow structure.

[0016] Further, a main controller and a hydraulic sensor are arranged inside the hydraulic power control console. The main controller is electrically connected to the hydraulic sensor. The main controller includes a CPU processing module, a signal receiving module, a signal processing module, a signal transmission module and a storage module; the hydraulic sensor transmits the hydraulic pressure to the signal receiving module in real time, and the signal receiving module transmits the received signal to the signal processing module in real time. The signal processing module is used to process the pressure value of the hydraulic sensor transmitted by the signal receiving module, and determine the tightening condition of the pipeline by comparing the pressure value with the set threshold. The signal processing module processes and transmits it to the CPU processing module through the signal transmission module. The CPU processing module controls the telescopic cylinder according to the determination result, and at the same time the storage module records the storage information.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] An adjustable chain-type hydraulic drive high-torque up and down coupling detection device proposed by the present invention can be arbitrarily adjusted to the outer diameter sizes of various pipe tools by setting a chain-type bendable bending fastener and through the cooperation of the special structure of the chain and the convex part.

The signal receiving module transmits the received signal to the signal processing module in real time. The signal processing module is used to process the pressure value of the hydraulic sensor transmitted by the signal receiving module. When the hydraulic pressure of the hydraulic sensor is greater than the set threshold, the signal processing module processes and transmits it to the CPU processing module through the signal transmission module. The CPU processing module immediately suspends the control of the telescopic cylinder, and at the same time, the storage module records and stores information. In this way, the hydraulic power control console can not only detect the screwing of the pipeline thread, but also determine whether the thread is tightened in place during screwing according to the pressure value, and can also avoid excessive rotation force during pipeline disassembly and damage the friction main clamp.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Such as Figures 1-2As shown in the figure, an adjustable chain-type hydraulic-driven high-torque up-and-down make-up and break-out detection device includes a hydraulic drive system composed of a hydraulic power control console 1 and a hydraulic actuator 5 connected to the hydraulic power control console 1 through a hydraulic oil pipe. The hydraulic actuator 5 is installed on one side of the upper end of a base 6 arranged on the ground. It also includes a support slide 7 installed on the other side of the upper end of the base 6. The support slide 7 is used to slidably install a friction back-up tong 2 and fixedly install a saddle 4 at its upper end. At the same time, the friction back-up tong 2 can slide and adjust on the support slide 7.

[0037] Specifically, when rotating and disassembling the pipeline 8 or detecting the tightening degree, the saddle 4 is used to adjust the horizontal height of the pipeline 8. The pipeline 8 passes through the middle of the friction back-up tong 2, and the middle of the pipeline 8 is wrapped by a friction main tong 3. At the same time, the driven end of the friction main tong 3 is movably connected to the driving end of the hydraulic actuator 5.

[0038] Preferably, as Figure 2 shown in the figure, the function of the saddle 4 is to cooperate with the friction back-up tong 2 to stably support the pipeline 8, which is not only convenient for the initial wrapping of the friction main tong 3, but also convenient for supporting the pipeline 8 after the pipeline 8 is removed by the friction main tong 3. It is a mechanism that can be adjusted up and down. The adjustment method can be hydraulic, pneumatic, or manual adjustment. Preferably, a simple manual adjustment method is proposed here. The saddle 4 specifically includes a lifting member 41 and a rotating disk 42 provided at the lower end of the lifting member 41. The rotating disk 42 is threadedly connected to the middle of the lifting member 41, and the upper end of the lifting member 41 is in an inverted V shape, which is convenient for supporting and wrapping pipelines 8 with different diameters. The lower end of the lifting member 41 is movably inserted into the inner side of a cylinder 43 installed at the upper end of the support slide 7. The lower end of the rotating disk 42 is rotatably connected to the cylinder 43. The lower end of the lifting member 41 is located in the cylinder 43 and is divided into two parts. The upper part is a threaded end and is threadedly connected to the rotating disk 42. When manually rotating the rotating disk 42, it can maintain a thread match with the threaded end, thereby driving the lifting member 41 to rise. The lower part is a square column end and is movably connected to the cylinder 43. The square column end is to prevent the lifting member 41 from rotating when the rotating disk 42 rotates with a thread match, so that the lifting member 41 can rise.

[0039] Furthermore, as Figure 3As shown in the figure, the hydraulic actuator 5 is jointly composed of a telescopic cylinder 51 and a lifting cylinder 52. The telescopic cylinder 51, the lifting cylinder 52, and the friction main clamp 3 are on the same horizontal plane. The lower ends of the telescopic cylinder 51 and the lifting cylinder 52 are both slidably arranged on the support 53 at the upper end of the base 6, which is used to adjust the wrapping position of the friction main clamp 3 when unclamping pipes 8 with different lengths. At the same time, both the telescopic cylinder 51 and the lifting cylinder 52 are connected to the hydraulic power control console 1 through oil pipes. There are two control handles on the hydraulic power control console 1. By rotating one of the control handles forward and backward, the lifting cylinder 52 can be controlled to extend and retract, which is convenient for lifting the friction main clamp 3 before operation. By rotating the other control handle forward and backward, the telescopic cylinder 51 can be controlled to extend and retract, and then the friction main clamp 3 can be driven to rotate forward and backward along the center of the pipe 8.

[0040] It should be added that, as Figure 1 shown, a main controller and a hydraulic sensor are arranged inside the hydraulic power control console 1. The main controller is electrically connected to the hydraulic sensor, and the main controller is also electrically connected to the two handles. The main controller includes a CPU processing module, a signal receiving module, a signal processing module, a signal transmission module, and a storage module;

[0041] The signal receiving module is used to receive the transmission signals from the handles and the hydraulic sensor. For example, here the hydraulic sensor is used as an example. The hydraulic sensor transmits the hydraulic pressure to the signal receiving module in real time;

[0042] The signal receiving module transmits the received signals to the signal processing module in real time. The signal processing module is used to process the pressure value of the hydraulic sensor transmitted by the signal receiving module. When the hydraulic pressure of the hydraulic sensor is greater than the set threshold, the signal processing module processes and transmits it to the CPU processing module through the signal transmission module. The CPU processing module immediately pauses the control of the telescopic cylinder 51, and at the same time the storage module records the storage information. In this way, the hydraulic power control console 1 can not only detect the tightening of the thread of the pipe 8, but also avoid excessive rotation force and damage to the friction main clamp 3 when disassembling the pipe 8.

[0043] Furthermore, as Figures 4-6 shown, the friction main clamp 3 includes a clamp handle 31 and a clamp jaw 32 installed at one end of the clamp handle 31 away from the telescopic cylinder 51. The rotation of the clamp handle 31 can drive the clamp jaw 32 to rotate synchronously. The connection method between the clamp handle 31 and the clamp jaw 32 can be a detachable fixing method such as screw fixing or pin fixing. As Figure 4 shown, the lower end of the clamp jaw 32 is formed in an eight - shaped, and the bottom wall surface of the eight - shaped is adapted to the pipe 8.

[0044] The clamping jaws 32 are located at both ends of the figure-eight opening and are also provided with a left channel and a right channel running through them. A freely bendable bending fastener 33 is disposed through the left channel and the right channel. The bending fastener 33 has a chain structure composed of a plurality of links and rollers. The middle part of the link is bent inward to form a bent part, and the opposite links and rollers form a movable hole.

[0045] As Figure 4 shown, one end of the bending fastener 33 is inserted from the lower end of the left channel and is preliminarily connected and fixed by a nut 37 inserted from the upper end of the left channel, that is, one end of the bending fastener 33 is fixed on the clamping jaw 32. Then, the free end of the bending fastener 33 bypasses the pipe 8 and is inserted into the right channel and passes out from one end of the clamping handle 31, or is first inserted into the right groove and passes out from one end of the clamping handle 31, and then the pipe 8 passes through the approximately circular space formed by the bending fastener 33 and the clamping jaw 32.

[0046] Furthermore, the free end of the bending fastener 33 on the clamping handle 31 is restricted by a locking component provided on the clamping handle 31. When the clamping handle 31 is reversed, the locking component restricts the bending fastener 33 from moving and rotates the pipe 8. When the clamping handle 31 rotates forward, the locking component does not restrict the bending fastener 33 from moving, and the bending fastener 33 can move slightly around the pipe 8, that is, when the clamping handle 31 rotates forward, it will not drive the pipe 8 to rotate.

[0047] Specifically, the following two embodiments are provided for the locking component. In the first embodiment, when the free end of the bending fastener 33 passes through the clamping handle 31, it needs to pass between the main clamping lock pin 34 provided on the inner side of the clamping handle 31 and the adjusting lock fastener 35 in the open state. The gap between the main clamping lock pin 34 and the adjusting lock fastener 35 in the locked state is slightly smaller than the bent part of the bending fastener 33.

[0048] The adjusting lock fastener 35 is composed of a lock main block 351 and a lock handle 352. The lock main block 351 and the lock handle 352 can be welded or integrally cast. A convex part 353 is provided at the upper end of one side of the lock main block 351, and a smooth part 354 is provided at the lower end of the lock main block 351 on the same side as the convex part 353. The lock main block 351 can rotate along the central pin 311 fixedly provided on the clamping handle 31. The central pin 311 is fixedly connected to the clamping handle 31. When the convex part 353 rotates along the central pin 311 and contacts the bending fastener 33, it is the locked state of the bending fastener 33 at this time. When the smooth part 354 rotates along the central pin 311 and contacts the bending fastener 33, it is the unlocked state of the bending fastener 33 at this time.

[0049] Further, regarding how to control the locking or unlocking of the bent fastener 33, an adjustment assembly 36 needs to be provided at the connection between the lock handle 352 and the main lock block 351. By rotating the adjustment assembly 36, different positions of it are buckled on the shift lever 360 provided on the inner side of the pliers handle 31 to control the locking of the main lock block 351, and further enable the main lock block 351 to control the locking or unlocking of the bent fastener 33.

[0050] More specifically, the adjustment assembly 36 includes an adjustment claw 361 and an elastic member 362 installed at the upper end of the adjustment claw 361. The upper end of the adjustment claw 361 is rotatably connected to the lock handle 352 through a cylinder, and the elastic member 362 is sleeved outside the cylinder. One end of the elastic member 362 is fixedly connected to the adjustment claw 361 and the other end is fixedly connected to the lock handle 352. The elastic member 362 can be a spring or elastic rubber, etc. By dialing the adjustment claw 361 outwards, the lock handle 352 can drive the protrusion 353 to rotate forward along the central pin 311, so that the smooth portion 354 contacts the bent fastener 33. Then release the adjustment claw 361 so that the adjustment claw 361 buckles on the shift lever 360 to complete the unlocking of the bent fastener 33, which is convenient for adjusting the bent fastener 33. Similarly, the protrusion 353 can be controlled to rotate reversely along the central pin 311 so that the protrusion 353 contacts the bent fastener 33, and finally the locking of the bent fastener 33 is completed.

[0051] Furthermore, a lower opening 364 and an upper opening 363 are formed on one side of the adjustment claw 361, and both the lower opening 364 and the upper opening 363 are adapted to the shift lever 360. When the lower opening 364 is adapted to the shift lever 360, the bent fastener 33 is in the locked state at this time. When the upper opening 363 is adapted to the shift lever 360, the bent fastener 33 is in the unlocked state at this time.

[0052] Further, a tooth plate 321 is also embedded in the bottom wall surface of the pliers jaw 32. The tooth plate 321 can increase the biting force on the pipe 8. The material of the tooth plate 321 can be plastic, rubber, silica gel or even metal material. As the most preferred, rubber material can be selected, especially wear-resistant rubber, which not only improves the wear resistance effect of the tooth plate 321, but also can reduce the surface damage to the pipe 8, and can further increase the biting force on the pipe 8 through the rubber deformation effect.

[0053] In order to prevent the pipe 8 from being screwed back tightly when disassembling the pipe 8 and facilitate the support of the disassembled pipe 8, as Figures 4-7As shown in the figure, the friction back clamp 2 includes a support platform 21 and a locking component 22 installed at the upper end of the support platform 21. The support platform 21 is movably connected to the upper end of the support slide 7. The locking component 22 is composed of the same mechanism as the upper part of the friction main clamp 3, including a jaw 32, a nut 37, a bent fastener 33, a main clamp locking pin 34, an adjusting locking fastener 35, a center pin 311, an adjusting assembly 36, and a stop lever 360. The jaw 32, the main clamp locking pin 34, the adjusting locking fastener 35, the center pin 311, the adjusting assembly 36, and the stop lever 360 are all installed on the support platform 21. When disassembling the pipeline 8, when the pliers handle 31 rotates forward, the pipeline 8 will be slightly locked by the corresponding bent fastener 33 of the locking component 22, so that the pipeline 8 will not rotate. When the pliers handle 31 rotates in reverse, the pipeline 8 will be unlocked by the locking component 22, so that the pipeline 8 can rotate.

[0054] Specifically, the working principle of Embodiment 1 is as follows:

[0055] First, lift the pliers handle 31 by the lifting cylinder 52 to a height greater than the height of the pipeline 8, and place the entire shackle detection device under the pipeline 8;

[0056] Then wrap the bent fastener 33 on the friction back clamp 2 around the outside of the pipeline 8 and lock it, and adjust the saddle 4 so that the upper end of the saddle 4 supports the pipeline 8;

[0057] Then, pinch the adjusting claw 361 and the locking handle 352 with one hand at the same time to separate the adjusting claw 361 from the stop lever 360, and then rotate the locking handle 352 so that the upper opening 363 matches the stop lever 360. At this time, the smooth part 354 corresponds to the main clamp locking pin 34;

[0058] Insert one end of the bent fastener 33 into the inner side of one end of the jaw 32 and thread the nut 37 through the jaw 32 and one end of the bent fastener 33 to connect them, so that one end of the bent fastener 33 is fixed on the jaw 32. Pass the bent fastener 33 through between the smooth part 354 and the main clamp locking pin 34 until it is relatively difficult to pull the bent fastener 33, and then operate the adjusting claw 361 and the locking handle 352 in reverse so that the protruding part 353 corresponds to the bent end of the bent fastener 33.

[0059] Based on the above, when it is necessary to disassemble the pipeline 8, lower the lifting cylinder 52, then drive the telescopic cylinder 51 to move upward, thereby driving the entire friction main clamp 3 to rotate along the axis of the pipeline 8. At this time, the position of the bending fastener 33 between the main clamp lock pin 34 and the adjustment lock fastener 35 is pulled upward under the reverse acting force of the pipeline 8. At this time, the bending fastener 33 is pulled, and the convex portion 353 rotates along the axis of the central pin 311. And at this time, the pulling force is slightly greater than the pulling force of the elastic member 362, and the convex portion 353 can be loosened. At the same time, the pipeline 8 is slightly locked by the friction back clamp 2. Therefore, the bending fastener 33 is not in sufficient contact with the pipeline 8. So when the bending fastener 33 rotates, the pipeline 8 does not move. When the friction main clamp 3 rotates to a certain angle, reverse drive the telescopic cylinder 51 to move downward. At this time, the bending fastener 33 moves downward, and the bending fastener 33 is locked by the convex portion 353 at this time. The convex portion 353 is blocked by the shift lever 360 and cannot rotate. Then, under the frictional force between the bending fastener 33 and the pipeline 8, the pipeline 8 is driven to rotate. Repeatedly perform the above operations to disassemble the pipeline 8.

[0060] When it is necessary to detect the tightening degree of the pipeline 8, drive the telescopic cylinder 51 to move upward to make the friction main clamp 3 rotate and move a certain angle, and then drive the telescopic cylinder 51 to move downward. The bending fastener 33 drives the pipeline 8 to rotate. At this time, the hydraulic sensor receives the hydraulic pressure and transmits the signal to the signal receiving module. The signal receiving module receives the implementation data. When the hydraulic pressure of the hydraulic sensor is less than the set threshold, it indicates that the pipeline 8 is loose at this time, and the pipeline 8 is detected to be loose at this time. At the same time, the storage module records and stores the information. At this time, the further bending fastener 33 continues to rotate. When the hydraulic pressure of the hydraulic sensor is greater than or equal to the set threshold, the signal processing module processes and transmits it to the CPU processing module through the signal transmission module. The CPU processing module immediately suspends the control of the telescopic cylinder 51, completes the detection of the pipeline 8 and tightens the pipeline 8 at the same time.

[0061] As Figures 8-9 In the second embodiment shown, the free end of the bending fastener 33 needs to pass through between the main clamp lock pin 34 and the central pin 311 provided on the inner side of the clamp handle 31 when passing through the clamp handle 31. Both the main clamp lock pin 34 and the central pin 311 are movably connected to the clamp handle 31. A locking pin 38 is threadedly installed at the middle position of the upper end of the clamp handle 31. The middle part of the locking pin 38 is inserted into the bending part of the bending fastener 33. Wherein the diameter of the locking pin 38 is smaller than the length of the movable hole of the bending fastener 33.

[0062] Furthermore, the working principle of the second embodiment is as follows:

[0063] First, use the lifting cylinder 52 to lift the clamp handle 31 to a height greater than the height of the pipeline 8, and place the entire shackle detection device under the pipeline 8;

[0064] Wrap the bending fastener 33 on the friction back clamp 2 around the outside of the pipeline 8 and lock it, adjust the saddle 4 so that the upper end of the saddle 4 supports the pipeline 8;

[0065] Pass the bending fastener 33 through between the central pin 311 and the main clamp locking pin 34, then pull the bending fastener 33 until it can no longer be pulled. At this time, the locking pin 38 penetrates through the bending fastener 33 and is threadedly connected to the clamp handle 31. Drive the telescopic cylinder 51 to move upward. The free end of the bending fastener 33 will move towards the connection end of the clamp handle 31 and the telescopic cylinder 51. At this time, the gap of the bending fastener 33 allows the locking pin 38 to move inside, so that the bending fastener 33 will not be restricted by the locking pin 38 and will not drive the pipeline 8 to rotate. Drive the telescopic cylinder 51 to move downward so that the movement of the bending fastener 33 is blocked by the locking pin 38, and then the pipeline 8 can be driven to rotate. The disassembly, installation and detection of the pipeline 8 can be carried out flexibly. The disadvantage of the second embodiment relative to the first embodiment is that the locking pin 38 has poor stability and is easily bent or pulled to move, and it is also easy to pull and damage the bending fastener 33, and it is not convenient for the bending fastener 33 to pass through between the central pin 311 and the main clamp locking pin 34. Most preferably, the second embodiment and the first embodiment can be used in combination, with high stability, but the structural cost increases, which can be adjusted according to actual needs.

[0066] Furthermore, as Figure 4 shown, the bending fastener 33 can be an entire chain, or can be a component composed of the connecting portion 331, the elastic portion 332 and the free end portion 333 as Figure 10 described. One end of the elastic portion 332 is fixedly connected to the connecting portion 331 and the other end is fixedly connected to the free end portion 333. Both the free end portion 333 and the connecting portion 331 are chains, and the elastic portion 332 can be one of rubber, silica gel and flexible plastic, and can be set as a hollow structure. At the same time, the elastic portion 332 is coated on the arc surface of the pipeline 8 close to the connecting portion 331. In this way, when the bending fastener 33 drives the pipeline 8 to rotate, the original line contact of the chain becomes the surface contact of the hollow elastic portion 332, and the elastic portion 332 occupies the entire force point surface of the bending fastener 33 for rotating the pipeline 8, thereby increasing the rotational force for tightening or removing the pipeline 8 during the detection of the bending fastener 33 on the pipeline 8 and improving the use effect.
