[0002] In oil drilling, pipes are used a lot, and these pipes often need to be disassembled or installed. Pipes in special locations also need to be tested for rotation, and pipe shackles are a key operation. When it is necessary to disassemble the pipe column, first use appropriate tools, such as hydraulic tongs. Clamp the pipe column joint with the tongs, and apply reverse torque by controlling the hydraulic system to gradually loosen the connected threads. There are also manual operations for tightening and loosening the threads of pipes and tool joints.

[0003] The disclosure discloses a drill pipe disassembly device and a method for using the device, which is published as CN114658375A. The device comprises: a fixed frame for installation on the drill pipe; a sliding member slidably mounted on the fixed frame and installed on an adjacent drill pipe; and a handle mounted on the fixed frame and drivingly connected to the sliding member. By rotating the handle, the sliding member is driven to move along the fixed frame, thereby driving the 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 drill pipe disassembly is difficult. By separating the two connected drill pipes through the disassembly device, manual disassembly of the drill pipe can be avoided, which saves time and effort, avoids damage to the equipment, reduces safety hazards, and is suitable for narrow construction environments.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 2 As shown, an adjustable chain type hydraulically driven high torque upper and lower breakaway detection device comprises a hydraulic power console 1 and a hydraulic drive system consisting of a hydraulic actuator 5 connected to the hydraulic power console 1 through a hydraulic oil pipe, wherein the hydraulic actuator 5 is installed on one side of the upper end of a base 6 arranged on the ground, and further comprises a support slide 7 installed on the other side of the upper end of the base 6, wherein the support slide 7 is used for slidingly installing a friction backing clamp 2 and a fixedly installed saddle 4 at its upper end, and the friction backing clamp 2 can be slidably adjusted on the support slide 7; Specifically, when rotating and disassembling the pipe 8 or checking the tightening degree, the saddle 4 is used to adjust the horizontal height of the pipe 8, and the pipe 8 passes through the middle part of the friction backup tongs 2, and the middle part of the pipe 8 is wrapped by the friction main tongs 3. At the same time, the driven end of the friction main tongs 3 is movably connected with the driving end of the hydraulic actuator 5.

[0026] As a preferred example, Figure 2 As shown, the function of the saddle 4 is to cooperate with the friction back-up tongs 2 to stably support the pipe 8, which is not only convenient for the initial covering of the friction main tongs 3, but also convenient for supporting the pipe 8 after the friction main tongs 3 are removed. It is a mechanism that can be adjusted up and down, and the adjustment method can be hydraulic, pneumatic, or manually adjusted. Preferably, a simple manual adjustment method is proposed here. The saddle 4 specifically includes a lifting member 41 and a rotating disk 42 arranged at the lower end of the lifting member 41. The rotating disk 42 is threadedly connected to the middle part of the lifting member 41, and the upper end of the lifting member 41 is in an inverted eight-shaped shape, so that To support and cover pipes 8 of different diameters, the lower end of the lifting member 41 is movably inserted into the inner side of the cylinder 43 installed on the upper end of the supporting slide 7, and 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 on 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 the rotating disk 42 is manually rotated, the thread can be matched 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 is threadedly matched and rotated, thereby allowing the lifting member 41 to rise.

[0027] Further, such as Figure 3 As shown, the hydraulic actuator 5 is 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, and the lower ends of the telescopic cylinder 51 and the lifting cylinder 52 are slidably arranged on a support 53 at the upper end of the base 6, which are used to adjust the covering position of the friction main clamp 3 when the pipes 8 of different lengths are shackled. At the same time, the telescopic cylinder 51 and the lifting cylinder 52 are connected to the hydraulic power console 1 through oil pipes. Two control handles are provided on the hydraulic power console 1. By rotating one of the control handles forward and reverse, the lifting cylinder 52 can be controlled to extend and retract, thereby facilitating the lifting of the friction main clamp 3 before operation, and by rotating the other control handle forward and reverse, the telescopic cylinder 51 can be controlled to extend and retract, thereby driving the friction main clamp 3 to rotate forward and reverse along the center of the pipe 8.

[0028] It should be added that Figure 1As shown, a main controller and a hydraulic sensor are arranged inside the hydraulic power console 1, the main controller is electrically connected to the hydraulic sensor, and the main controller is also electrically connected to the two handles, wherein 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 signal receiving module is used to receive the transmission signals of the handle and the hydraulic sensor. For example, a hydraulic sensor is used as an example here. The hydraulic sensor transmits the hydraulic pressure to the signal receiving module in real time. 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 51, and the storage module records the storage information. In this way, the hydraulic power console 1 can not only perform thread tightening detection on the pipeline 8, but also avoid excessive rotation force to damage the friction main clamp 3 when disassembling the pipeline 8.

[0029] Further, such as Figure 4-Figure 6 As shown, the friction master pliers 3 includes a pliers handle 31 and a pliers jaw 32 installed at one end of the pliers handle 31 away from the telescopic cylinder 51. The rotation of the pliers handle 31 can drive the pliers jaw 32 to rotate synchronously. The connection method between the pliers handle 31 and the pliers jaw 32 can be a detachable fixing method such as screw fixing, pin fixing, etc., such as Figure 4 As shown, the lower end of the clamp jaw 32 is opened into an eight-shaped shape, and the bottom wall of the eight-shaped shape is matched with the pipeline 8.

[0030] The jaws 32 are provided with a left channel and a right channel at both ends of the eight-shaped opening, and a freely bendable bending fastener 33 is provided in the left channel and the right channel. The bending fastener 33 is a chain structure composed of a plurality of chain links and rollers, wherein the middle part of the chain link is bent inwardly to form a bending part, and the opposite chain link and the roller form a movable hole; like Figure 4 As shown, one end of the bent fastener 33 is inserted from the lower end of the left channel and then preliminarily connected and fixed by the nut 37 inserted from the upper end of the left channel, that is, one end of the bent fastener 33 is fixed on the clamp jaw 32, and then the free end of the bent fastener 33 bypasses the pipe 8 and is inserted into the right channel and passes through one end of the clamp handle 31, or is first inserted into the right groove and passes through one end of the clamp handle 31, and then the pipe 8 passes through the approximately circular space enclosed by the bent fastener 33 and the clamp jaw 32.

[0031] Furthermore, the free end of the bent fastener 33 on the clamp handle 31 is restricted by the locking assembly provided on the clamp handle 31, and when the clamp handle 31 is reversed, the locking assembly restricts the bent fastener 33 from moving, thereby rotating the pipe 8. When the clamp handle 31 rotates forward, the locking assembly does not restrict the movement of the bent fastener 33, and the bent fastener 33 can move slightly around the pipe 8, that is, the pipe 8 will not be driven to rotate when the clamp handle 31 rotates forward.

[0032] Specifically, the locking assembly is provided with the following two embodiments, wherein in the first embodiment, the free end of the bent fastener 33 needs to pass through between the main pliers locking pin 34 provided on the inner side of the pliers handle 31 and the adjusting locking member 35 in the open state when passing through the pliers handle 31, and the gap between the main pliers locking pin 34 and the adjusting locking member 35 in the locked state is slightly smaller than the bent portion of the bent fastener 33.

[0033] The adjusting lock member 35 is composed of a lock main block 351 and a lock handle 352, which can be welded or cast as one piece, wherein a protrusion 353 is provided on the upper end of one side of the lock main block 351, and a smooth portion 354 is provided on the lower end of the lock main block 351 on the same side of the protrusion 353, and the lock main block 351 can rotate along the center pin 311 fixedly set on the clamp handle 31, and the center pin 311 is fixedly connected to the clamp handle 31, when the protrusion 353 rotates along the center pin 311 and contacts the bent fastener 33, the bent fastener 33 is in a locked state, and when the smooth portion 354 rotates along the center pin 311 and contacts the bent fastener 33, the bent fastener 33 is in an unlocked state.

[0034] Furthermore, in order to control the locking or unlocking of the bent fastener 33, it is necessary to set an adjustment component 36 at the connection between the locking handle 352 and the lock main block 351. The adjusting component 36 is rotated to make its different positions buckle on the gear lever 360 set on the inner side of the clamp handle 31 to control the locking of the lock main block 351, thereby enabling the lock main block 351 to control the locking or unlocking of the bent fastener 33.

[0035] The cam 362 is a spring-loaded structure that allows the cam 363 to be moved in a direction that is perpendicular to the axis of the locking member 352. The cam 362 is a spring-loaded structure that allows the cam 363 to be moved in a direction that is perpendicular to the axis of the locking member 352. The cam 362 is a spring-loaded structure that allows the cam 363 to be moved in a direction that is perpendicular to the axis of the locking member 352.

[0036] Furthermore, a lower opening 364 and an upper opening 363 are provided on one side of the adjusting claw 361, and both the lower opening 364 and the upper opening 363 are matched with the gear lever 360. When the lower opening 364 is matched with the gear lever 360, the bent fastener 33 is in a locked state, and when the upper opening 363 is matched with the gear lever 360, the bent fastener 33 is in an unlocked state.

[0037] Furthermore, a tooth plate 321 is embedded in the bottom wall of the jaw 32, and the tooth plate 321 can increase the meshing force on the pipe 8. The material of the tooth plate 321 can be plastic, rubber, silicone or even metal. As the most preferred material, rubber material, especially wear-resistant rubber, can be selected, which not only improves the wear resistance of the tooth plate 321, but also reduces the surface damage to the pipe 8, and can increase the meshing force on the pipe 8 through the rubber deformation effect.

[0038] In order to prevent the pipeline 8 from being reversely tightened when it is disassembled and to facilitate the support of the disassembled pipeline 8, as shown in FIG. Figure 4-Figure 7 As shown, the friction back-up tongs 2 include a support platform 21 and a locking component 22 installed on 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 friction main tongs 3, including a tongs jaw 32, a nut 37, a bent fastener 33, a main tongs locking pin 34, an adjustment locking component 35, a center pin 311, an adjustment assembly 36 and a shift rod 360, wherein the tongs jaw 32, the main tongs locking pin 34, the adjustment locking component 35, the center pin 311, the adjustment assembly 36 and the shift rod 360 are all installed on the support platform 21, when the pipe 8 is disassembled, when the tongs handle 31 rotates forward, the pipe 8 will be slightly locked by the bent fastener 33 corresponding to the locking component 22, so that the pipe 8 will not rotate, and when the tongs handle 31 is reversed, the pipe 8 will be unlocked by the locking component 22, so that the pipe 8 can rotate.

[0039] Specifically, the working principle of the first embodiment is as follows: First, the lifting cylinder 52 is used to raise the clamp handle 31 to a height greater than the height of the pipe 8, and the entire shackle detection device is placed on the lower side of the pipe 8; Then wrap the bent fastener 33 on the friction back clamp 2 around the outside of the pipe 8 and tighten it, and adjust the saddle 4 so that the upper end of the saddle 4 supports the pipe 8; Then, the adjusting claw 361 and the locking handle 352 are pinched by one hand at the same time to separate the adjusting claw 361 from the shift rod 360, and then the locking handle 352 is rotated to make the upper opening 363 match the shift rod 360, at which time the smooth portion 354 corresponds to the main pliers locking pin 34; Insert one end of the bent fastener 33 into the inner side of one end of the jaw 32 and insert the nut 37 into the jaw 32 to threadably connect it with one end of the bent fastener 33, so that one end of the bent fastener 33 is fixed on the jaw 32, pass the bent fastener 33 between the smooth portion 354 and the main pliers locking pin 34 until it becomes relatively difficult to pull the bent fastener 33, and then reversely operate the adjusting claw 361 and the locking handle 352 so that the protrusion 353 corresponds to the bent end of the bent fastener 33.

[0040] Based on the above, when the pipe 8 needs to be disassembled, the lifting cylinder 52 is moved downward, and then the telescopic cylinder 51 is driven to move upward, thereby driving the entire friction main pliers 3 to rotate along the axis of the pipe 8. At this time, the position of the bent fastener 33 located between the main pliers locking pin 34 and the adjusting lock fastener 35 is pulled upward under the reverse force of the pipe 8. At this time, the bent fastener 33 is pulled, and the protrusion 353 rotates along the axis of the center pin 311. The pulling force at this time is slightly greater than the pulling force of the elastic member 362, and the protrusion 353 can be loosened. At the same time, the pipe 8 is slightly locked by the friction back-up pliers 2, so the bending fastener 33 is not in sufficient contact with the surrounding pipe 8, so the pipe 8 does not move when the bending fastener 33 rotates. When the friction main pliers 3 rotates to a certain angle, the telescopic cylinder 51 is driven in the reverse direction to move downward. At this time, the bending fastener 33 moves downward. The bending fastener 33 is locked by the protrusion 353 at this time. The protrusion 353 is blocked by the gear lever 360 and will not rotate. Then, the friction force between the bending fastener 33 and the pipe 8 drives the pipe 8 to rotate. The above operations are repeated to disassemble the pipe 8.

[0041] When it is necessary to detect the tightness of the pipeline 8, the telescopic cylinder 51 is driven to move upward so that the friction main clamp 3 rotates and moves a certain angle, and then the telescopic cylinder 51 is driven to move downward, and 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 means that the pipeline 8 is loose at this time. At this time, the loose pipeline 8 is detected. At the same time, the storage module records the storage 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.

[0042] like Figure 8-9 In the second embodiment shown, the free end of the bending fastener 33 needs to pass through the main pliers locking pin 34 and the center pin 311 arranged on the inner side of the pliers handle 31 when passing through the pliers handle 31. The main pliers locking pin 34 and the center pin 311 are both movably connected to the pliers handle 31. A locking pin 38 is threadedly installed at the middle position of the upper end of the pliers 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.

[0043] Furthermore, the working principle of the second embodiment is as follows: First, the lifting cylinder 52 is used to raise the clamp handle 31 to a height greater than the height of the pipe 8, and the entire shackle detection device is placed on the lower side of the pipe 8; Then wrap the bent fastener 33 on the friction back clamp 2 around the outside of the pipe 8 and tighten it, and adjust the saddle 4 so that the upper end of the saddle 4 supports the pipe 8; The bent fastener 33 is passed through between the center pin 311 and the main clamp locking pin 34, and then the bent fastener 33 is pulled until it cannot be pulled. At this time, the locking nail 38 passes through the bent fastener 33 and is threadedly connected to the clamp handle 31, driving the telescopic cylinder 51 to move upward, and the free end of the bent fastener 33 moves toward the connection end of the clamp handle 31 and the telescopic cylinder 51. At this time, the gap of the bent fastener 33 allows the locking nail 38 to move inside, so that the bent fastener 33 will not be restricted by the locking nail 38, and will not drive the pipe 8 to rotate, driving the telescopic cylinder 51 to move downward The movement of the bent fastener 33 is blocked by the locking pin 38, which can drive the pipe 8 to rotate, and the pipe 8 can be flexibly disassembled, installed and tested. 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 moved, and it is also easy to pull and damage the bent fastener 33, and the bent fastener 33 is not convenient to pass between the center pin 311 and the main clamp locking pin 34. Most preferably, the second embodiment can be used in combination with the first embodiment, which has high stability, but the structural cost is increased and can be adjusted according to actual needs.

[0044] Furthermore, if Figure 4 As shown, the curved fastener 33 can be a whole chain or can be as shown in FIG. Fig.10 The connecting portion 331, the elastic portion 332 and the free end portion 333 constitute an assembly, wherein 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. The free end portion 333 and the connecting portion 331 are both chains, and the elastic portion 332 can be made of rubber, silicone and flexible plastic, and can be set to a hollow structure. At the same time, the elastic portion 332 is coated on the arc surface of the pipe 8 close to the connecting portion 331, so that when the bending fastener 33 drives the pipe 8 to rotate, the original chain line contact is changed to the surface contact of the hollow elastic portion 332, and the elastic portion 332 occupies the entire bending fastener 33 force point surface for rotating the pipe 8, thereby increasing the rotational force of the bending fastener 33 to tighten or remove the pipe 8 during detection, thereby improving the use effect.
