Description

Technical Field

[0001] The invention relates to the technical field of hydraulic pliers maintenance, and in particular to a hydraulic pliers teeth adjustment and replacement device and a use method thereof. Background Art

[0002] Hydraulic pliers are usually used for lifting and lowering oil pipes at the construction site of oil and gas wells. A tooth block track and two telescopic pins are set on the jaw plate of the inner cavity of the hydraulic pliers. A tooth block is installed on the tooth block track. Two telescopic pins set along the length of the tooth block track fix the tooth block on the tooth block track. The tooth block is used to increase the friction when the hydraulic pliers clamp the oil pipe, but the contact part between the tooth block and the oil pipe is easy to wear, so the tooth block needs to be replaced frequently.

[0003] The hydraulic pliers tooth block disassembler used in the related art includes a rod-shaped tool with a sharp end, such as a screwdriver. The tip of the screwdriver is used to press down the telescopic pin until the telescopic pin is flush with the jaw plate, and then the tooth block is quickly pushed out and the screwdriver is pulled out at the same time.

[0004] In the process of realizing the present invention, the inventors found that the above method has at least the following defects: in the related art, after pressing down the telescopic pin, it is necessary to find the right time to quickly push out the tooth block and grab the tooth block to prevent it from falling into the well, and at the same time, the screwdriver must be pulled out, which is difficult to operate.

[0005] The existing announcement number CN109986507 B provides a hydraulic pliers tooth block disassembler, which is realized by pressing down the telescopic pin that is closer to the push rod among the two telescopic pins through the push rod, and using the conical end of the push rod to press down the telescopic pin. At this time, although the conical end of the push rod contacts the end face of the telescopic pin, it does not completely cover the end face of the telescopic pin. When the telescopic pin is retracted into the jaw plate, the tooth block is pushed to move by the tooth block booster, and the tooth block is adsorbed by the magnetic component. When the end face of the telescopic pin is flush with the surface of the jaw plate, push the tooth block booster. After the tooth block is against part of the end face of the telescopic pin, release the push rod and continue to push the tooth block booster until the tooth block is separated from the jaw plate. At this time, the magnetic component adsorbs the tooth block to the bracket, and the operation is completed.

[0006] However, due to the small operating space at the tooth block, it is impossible to ensure by observation that the end face of the telescopic pin is flush with the surface of the jaw plate by pushing the conical end of the push rod. When the shrink pin protrudes from the surface of the jaw plate, the shrink pin continues to clamp the tooth block, making it difficult to disassemble. When the shrink pin is retracted into the mounting hole of the shrink pin, the conical end of the push rod protrudes from the surface of the jaw plate, and then the tooth block booster is pushed. After the tooth block contacts part of the end face of the telescopic pin, the push rod is released and the tooth block booster is continued to be pushed until the tooth block is separated from the jaw plate. The operation process is relatively cumbersome.

[0007] Therefore, it is necessary to provide a hydraulic pliers teeth adjustment and replacement device and a method of using the same to solve the above-mentioned technical problems. Summary of the invention

[0051] like Figure 5 As shown, Figure 5 It is a schematic diagram of the structure of the jaws and tooth blocks in the hydraulic pliers;

[0052] There are two tooth block mounting grooves 71 on the jaw 7, and pin mounting holes 75 are respectively provided at both ends of each tooth block mounting groove 71, and telescopic pins 72 are installed in the pin mounting holes 75. A tooth block 74 is assembled in the tooth block mounting groove 71, and pin grooves 73 are respectively provided at both ends of the tooth block 74. The telescopic pin 72 is in the pin groove 73, and the tooth block 74 is fixed in the tooth block mounting groove 71. The cross-sections of the tooth block mounting groove 71 and the tooth block 74 are both trapezoidal, which ensures that the tooth block 74 will not be displaced forward and backward in the tooth block mounting groove 71.

[0053] Working principle: The initial state of the device is that the end of the second round tube 316 is retracted into the guide cylinder 317;

[0054] When using the device to disassemble the teeth of the pliers, first hold the L-shaped handle 1 to place the device on one side of the tooth block 74 to be disassembled, and make the two pairs of clamps 45 and the two guide cylinders 317 respectively at one end of the tooth block 74, such as Figure 8As shown, the operation controller 6 controls the motor 1 31 to rotate and drive the reverse screw rod 1 33 to rotate, and the reverse screw rod 1 33 drives the two sliders 1 34 to move in the direction of approaching each other, and the two sliders 1 34 drive the L-shaped support plate 35, the spline shaft 36, the round shaft 1 38, the rotary joint 23, the round shaft sleeve 1 39, the round tube 1 310, the round shaft sleeve 2 311, the round tube 2 316, the guide cylinder 317 and the round shaft 2 318 to move in the direction of approaching each other, and the spline shaft 36 slides along the spline shaft sleeve 37. When the two guide cylinders 317 are respectively against the pin grooves 73 of the tooth block 74, , turn off the motor 1 31, at this time the round tube 2 316 corresponds to the telescopic pin 72 of the fixed tooth block 74, and then the controller 6 controls the motor 3 41 to rotate and drive the corresponding reverse screw rod 2 43 to rotate, and the reverse screw rod 2 43 is driven by two gears 49 to make another reverse screw rod 2 43 rotate synchronously, and the two reverse screw rods 2 43 drive the two pairs of sliders 2 44 and the clamping plate 45 to move in a direction close to each other, and when the clamping plate 45 abuts against the two ends of the tooth block 74, the motor 3 41 is controlled to be turned off, so that the device fixes the tooth block 74 and prevents the tooth block 74 from falling after disassembly;

[0055] Then, the micro air compressor 21 is controlled to be turned on. Since one end of the L-shaped channel 24 is blocked by the round sleeve 39, the high-pressure gas generated by the micro air compressor 21 is stored in the closed cavity formed by the air pipe 22, the rotary joint 23, the L-shaped channel 24 and the round sleeve 39. Then, the L-shaped handle 1 is pulled upward or pressed downward by hand, so that the device as a whole is subjected to an upward or downward force. Then, the motor 31 is started to drive the power bevel gear 313 to rotate, and the power bevel gear 313 drives the driven bevel gear 312 and the spline sleeve 37 to rotate, and the spline sleeve 37 drives the spline shaft 36 and the round shaft 38 to rotate. The circular shaft 1 38 rotates in the circular shaft sleeve 1 39. Since the spline shaft 36 is fixedly connected to the eccentric part of the circular shaft 1 38, the circular shaft 1 38 drives the circular shaft sleeve 1 39, the circular tube 1 310 and the circular shaft sleeve 2 311 to swing. The circular shaft sleeve 2 311 rotates with the circular shaft 2 318 as the central axis and drives the circular shaft 2 318 to move. The circular shaft 2 318 drives the circular tube 2 316 to slide along the guide cylinder 317. The circular tube 2 316 pushes the telescopic pin 72 to slide into the pin mounting hole 75. When the circular tube 2 316 extends from the guide cylinder 317 and moves to the farthest end, the end of the L-shaped channel 24 is connected with the connecting channel 25. Figure 7 As shown, the high-pressure gas in the L-shaped channel 24 is ejected from the injection pipe 26 through the connecting channel 25, and the high-pressure gas pushes the end of the telescopic pin 72 into the pin mounting hole 75, and the end of the round tube 316 will not exceed the contact surface between the tooth block 74 and the tooth block mounting groove 71. At this time, a certain gap is generated between the telescopic pin 72 and the end of the round tube 316, and the tooth block 74 loses the obstruction of the telescopic pin 72. The staff manually pulls the device upward or presses downward as a whole, and the tooth block 74 moves upward or downward to disengage from the tooth block mounting groove 71, thereby realizing the disassembly of the tooth block 74.

[0056] During installation, the controller 6 controls the motor 131 to rotate so that the two guide cylinders 317 are respectively against the pin grooves 73 of the tooth block 74, and the motor 341 of the controller 6 rotates so that the clamping plate 45 is against the two ends of the tooth block 74, so that the tooth block 74 to be installed is fixed on the device, and the L-shaped handle 1 is held to insert the lower end of the tooth block 74 from top to bottom into the tooth block installation groove 71. When the telescopic pin at the upper part is against the pin groove 73 at the lower end of the tooth block 74, the device is placed on the side of the tooth block 74 to be removed; control to start the micro air compressor 21, and the high-pressure gas generated by the micro air compressor 21 is stored in the closed cavity formed by the air pipe 22, the rotary joint 23, the L-shaped channel 24 and the round shaft sleeve 139, and then press the L-shaped handle 1 downward by hand to subject the device as a whole to a downward pressure; then start the motor 131, and the round tube 2316 pushes the telescopic pin When the second round tube 316 moves to the farthest end, the end of the L-shaped channel 24 is connected to the connecting channel 25, and the high-pressure gas in the L-shaped channel 24 is ejected from the injection pipe 26 through the connecting channel 25. The high-pressure gas pushes the end of the telescopic pin 72 into the pin mounting hole 75, so that a certain gap is generated between the telescopic pin 72 and the end of the second round tube 316. The tooth block 74 loses the obstruction of the telescopic pin 72, and under the action of the downward pulling force applied to the device as a whole by the staff by hand, the tooth block 74 slides downward into the tooth block mounting groove 71. When the two pin grooves 73 of the tooth block 74 correspond to the two telescopic pins 72, the upper telescopic pin 72 pops out to realize the installation and fixation of the tooth block 74. When the tooth block 74 needs to be installed from bottom to top, the operation process is opposite to the above operation and will not be repeated.

[0057] Beneficial effect: The device can use the clamping plate 45 of the clamping assembly 4 to press against the two ends of the tooth block 74, thereby achieving the fixation of the tooth block 74 by the device and preventing the tooth block 74 from falling off after disassembly; the round tube 2 316 can push the telescopic pin 72 to slide into the pin mounting hole 75, and the spacing between the two round tubes 2 316 can be adjusted, and can be adjusted automatically according to the spacing of the two telescopic pins 72 of hydraulic pliers of different models, and has a wider applicability; two round tubes 2 316 are provided to push the two telescopic pins 72 at the same time, and the two injection pipes 26 can pneumatically impact the two telescopic pins 72 at the same time, so as to facilitate the downward or upward disassembly of the tooth block 74.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

7. A method for using a hydraulic pliers teeth adjustment and replacement device, characterized in that: The hydraulic pliers teeth adjustment and replacement device according to any one of claims 1 to 6 comprises the following steps: S1: When using the device to disassemble the pliers teeth, first hold the L-shaped handle 1 to place the device on the side of the tooth block 74 that needs to be disassembled, and make the two pairs of clamps 45 and the two guide cylinders 317 respectively at one end of the tooth block 74, operate the controller 6 to control the motor 1 31 to rotate and drive the reverse screw 1 33 to rotate, so that the two circular shafts 2 318 move in the direction of approaching each other, when the two guide cylinders 317 are respectively against the pin grooves 73 of the tooth block 74, turn off the motor 1 31, at this time the circular tube 2 316 corresponds to the telescopic pin 72 of the fixed tooth block 74, and then the controller 6 controls the motor 3 41 to rotate and drive the corresponding reverse screw 2 43 to rotate, when the clamps 45 are against the two ends of the tooth block 74, control the motor 3 41 to turn off, so that the device fixes the tooth block 74 and prevents the tooth block 74 from falling after disassembly; S2: Then control to start the micro air compressor 21, and the high-pressure gas generated by the micro air compressor 21 is stored in the closed cavity formed by the air pipe 22, the rotary joint 23, the L-shaped channel 24 and the round sleeve 39; then pull the L-shaped handle 1 upward or press downward by hand, so that the device as a whole is subjected to an upward or downward force, and then start the motor 31, and through the transmission, the round tube 316 slides along the guide cylinder 317, and the round tube 316 pushes the telescopic pin 72 to slide into the pin installation hole 75. When the round tube 316 extends from the guide cylinder 317 and moves to the farthest end, the end of the L-shaped channel 24 is closed. The L-shaped channel 24 is connected to the connecting channel 25, and the high-pressure gas in the L-shaped channel 24 is ejected from the injection pipe 26 through the connecting channel 25. The high-pressure gas pushes the end of the telescopic pin 72 into the pin mounting hole 75, and the end of the round tube 316 will not exceed the contact surface between the tooth block 74 and the tooth block mounting groove 71. At this time, a certain gap is generated between the telescopic pin 72 and the end of the round tube 316, and the tooth block 74 loses the obstruction of the telescopic pin 72. The staff manually pulls the device upward or presses downward as a whole, and the tooth block 74 moves upward or downward to break away from the tooth block mounting groove 71, thereby realizing the disassembly of the tooth block 74. S3: When installing a new tooth block 74, the controller 6 controls the motor 31 to rotate so that the two guide cylinders 317 are respectively against the pin grooves 73 of the tooth block 74, and the motor 341 of the controller 6 rotates so that the clamping plate 45 is against the two ends of the tooth block 74, so that the tooth block 74 to be installed is fixed on the device, and the L-shaped handle 1 is held to insert the lower end of the tooth block 74 from top to bottom into the tooth block installation groove 71. When the telescopic pin at the upper part is against the pin groove 73 at the lower end of the tooth block 74, the device is placed on the side of the tooth block 74 to be removed; the micro air compressor 21 is controlled to be turned on, and the high-pressure gas generated by the micro air compressor 21 is stored in the closed cavity formed by the air pipe 22, the rotary joint 23, the L-shaped channel 24 and the round shaft sleeve 39, and then the L-shaped handle 1 is pressed downward by hand to cause the device as a whole to be subjected to a downward pressure. Then the motor 31 is started, and the second round tube 316 pushes the telescopic pin 72 to slide into the pin mounting hole 75. When the second round tube 316 moves to the farthest end, the end of the L-shaped channel 24 is connected to the connecting channel 25, and the high-pressure gas in the L-shaped channel 24 is ejected from the injection pipe 26 through the connecting channel 25. The high-pressure gas pushes the end of the telescopic pin 72 into the pin mounting hole 75, so that a certain gap is generated between the telescopic pin 72 and the second round tube 316 and the end, and the tooth block 74 loses the obstruction of the telescopic pin 72. Under the action of the downward pulling force applied to the device as a whole by the staff by hand, the tooth block 74 slides downward into the tooth block mounting groove 71. When the two pin grooves 73 of the tooth block 74 correspond to the two telescopic pins 72, the upper telescopic pin 72 pops out, and the tooth block 74 is installed and fixed.
