Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe welding tooling, in particular to a coiled tubing welding auxiliary device. Background Technique

[0002] Coiled tubing workover trucks are widely used in various operation fields such as oil drilling, well completion, well testing, oil production, workover, and gathering and transportation. During the operation of coiled tubing equipment, it is often necessary to carry out butt welding work on coiled tubing. The groove state, roundness, straightness, pollution, corrosion, and magnetization during the butt welding of coiled tubing will have a great impact on the performance of the weld.

[0003] According to the search, the Chinese patent document, publication number: CN211219457U, discloses a coiled tubing welding auxiliary device. One of the two oil pipes to be welded is installed on the first positioning support and the position of the oil pipe is fixed by a slip joint. Then, the base on the second installation support is moved towards the direction close to the first installation support, and then the rotating support on the second installation support is rotated by a specified angle. The other oil pipe is installed on the slip joint at the bottom of the rotating support, so that a certain angle is formed between the two oil pipes. Finally, the two oil pipes are welded into one body. However, during the use of this coiled tubing welding auxiliary device, since it is fixed by inserting the relevant part into the slip joint, and the device can only be inserted into the slip joint from one side through any end of the oil pipe, when encountering an oil pipe with a longer diameter, a large space is required to insert the oil pipe. Therefore, the device is limited during use and must be used in an open space. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a coiled tubing welding auxiliary device, which has the advantages of simple operation, small volume, strong clamping force, and wide applicability to oil pipes, and solves the above technical problems.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A coiled tubing welding auxiliary device, including an operation board, a telescopic box is installed on the left side of the operation board, a round hole is opened on one side of the telescopic box, a telescopic frame is installed inside the telescopic box, an elastic bead is installed on one side of the telescopic frame, a through hole is opened on the left side of the middle of the operation board, limit plates are installed on both sides of the through hole, an arc-shaped upper baffle is installed on the back of the limit plate, a strip-shaped groove is opened at the top of the arc-shaped upper baffle, a support frame is installed at the bottom of the operation board, a protective cover is installed inside the support frame, a cylinder is installed inside the protective cover, a cross bar is installed on the output shaft of the cylinder, and an arc-shaped lower clamping plate is installed at one end of the cross bar.

[0008] Preferably, the arc-shaped upper baffle cooperates with the arc-shaped lower clamping plate, and the arc-shaped lower clamping plate fits into the strip-shaped groove.

[0009] Through the above technical solution, the cooperative design of the arc-shaped upper baffle and the arc-shaped lower clamping plate can clamp and stabilize the coiled tubing. This clamping method can ensure that the welding object maintains a fixed position and angle during the welding process, preventing it from moving or shaking, thereby improving the welding accuracy and quality. Since the strip-shaped groove opened at the top of the arc-shaped upper baffle fits the arc-shaped lower clamping plate, it can adapt to coiled tubing of different diameters and shapes. The arc-shaped lower clamping plate can pass through the strip-shaped groove and fit the outer shape of the coiled tubing, thereby providing a better clamping effect. This design makes the welding auxiliary equipment applicable to coiled tubing of various specifications. This adjustability makes the welding auxiliary equipment more flexible and adaptable.

[0010] Preferably, the arc-shaped lower clamping plate passes through the inside of the through hole and is connected to one end of the cross bar.

[0011] Through the above technical solution, by controlling the telescopic movement of the cylinder, the position and clamping force of the arc-shaped lower clamping plate can be conveniently adjusted. Such an automated operation simplifies the manual operation in the welding process, improves work efficiency and consistency. Installing the cylinder at the bottom of the operation board and passing the arc-shaped lower clamping plate through the through hole in the operation board can effectively save space. Such a design makes the equipment more compact, reduces the floor area of the equipment, and provides more space and convenience for the working area. The cylinder, as a power source, has a stable power output and reliable working performance. Through proper design and adjustment, it can ensure that the clamping force is stable and reliable, maintaining the stable fixation of the welding object, thereby improving the welding quality and stability.

[0012] Preferably, the height of the limit plate is the same as the height when the telescopic frame is fully retracted into the telescopic box.

[0013] Through the above technical solution, with the limiting effect of the limiting plate, the excessive downward contraction of the arc-shaped lower clamping plate can be prevented, which can increase the stability of the welding auxiliary device. When the arc-shaped lower clamping plate contracts excessively, it may cause the device to be unstable or tilt, thus affecting the accuracy and stability of welding. With the limiting plate, the stable state of the device can be maintained, providing a more reliable welding environment. The height of the limiting plate is the same as the height when the telescopic frame is fully retracted into the telescopic box. This design makes the operation more convenient. The welder only needs to fully retract the telescopic frame to the height of the limiting plate to ensure that the arc-shaped lower clamping plate will not contract excessively. This simplifies the operation steps, reduces the possibility of human error, and improves work efficiency.

[0014] Preferably, the elastic bead fits with the round hole opened on one side of the telescopic box.

[0015] Through the above technical solution, through the cooperation of the elastic bead and the round hole, the telescopic device can achieve free expansion and contraction. When the device needs to expand, the elastic bead can easily slide through the round hole, allowing the extension of the telescopic frame. When the device needs to contract, the elastic bead can fit back into the round hole to keep the device compact. The elastic bead is usually made of wear-resistant and corrosion-resistant materials, such as spring steel or stainless steel. This material has good durability and can withstand long-term use and frequent expansion and contraction operations without being easily damaged. Therefore, the telescopic device connected by the elastic bead has a long service life.

[0016] Preferably, an anti-slip pad is installed at the bottom of the support frame.

[0017] Through the above technical solution, the anti-slip pad can effectively provide the friction force between the support frame and the ground, thereby increasing the stability of the device. This is very important for the safety and stability of the welding work because during the welding process, the accurate position and stability of the coiled tubing need to be maintained. During the welding process, the coiled tubing may be affected by the thermal expansion of the welding heat-affected zone and the forces during the welding process and slide or shift. By installing the anti-slip pad, the risk of sliding and shifting can be effectively reduced. During the welding process, relatively large vibrations and noises may be generated. The anti-slip pad has the functions of shock absorption and sound absorption, which can reduce the transmission of vibrations and noises and provide a relatively quiet and stable working environment.

[0018] Compared with the prior art, the utility model provides a coiled tubing welding auxiliary device, which has the following beneficial effects:

[0019] 1. Through the cooperative design of the arc-shaped upper baffle and the arc-shaped lower clamping plate, the utility model can clamp and stabilize the oil pipe. This clamping method can ensure that the welding object maintains a fixed position and angle during the welding process, preventing it from moving or shaking, thereby improving the welding accuracy and quality. Since the strip-shaped groove opened at the top of the arc-shaped upper baffle fits with the arc-shaped lower clamping plate, it can adapt to oil pipes of different diameters and shapes. The arc-shaped lower clamping plate can pass through the strip-shaped groove and fit with the outer shape of the oil pipe, thereby providing a better clamping effect.

[0020] 2. Through the limiting effect of the limiting plate, the utility model prevents the arc-shaped lower clamping plate from shrinking excessively downward, which can increase the stability of the welding auxiliary equipment. When the arc-shaped lower clamping plate shrinks excessively, it may cause the equipment to be unstable or tilt. The height of the limiting plate is the same as the height when the telescopic frame is fully retracted into the telescopic box. Just retract the telescopic frame to the height of the limiting plate to ensure that the arc-shaped lower clamping plate does not shrink excessively. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-3, A coiled tubing welding auxiliary device, including an operation board 1, a telescopic box 2 is installed on the left side of the operation board 1, a round hole 3 is opened on one side of the telescopic box 2, a telescopic frame 4 is installed inside the telescopic box, an elastic bead 5 is installed on one side of the telescopic frame 4, a through hole 6 is opened on the middle left side of the operation board 1, limiting plates 7 are installed on both sides of the through hole 6, an arc-shaped upper baffle 8 is installed on the back of the limiting plate 7, a strip-shaped groove 9 is opened at the top of the arc-shaped upper baffle 8, a support frame 10 is installed at the bottom of the operation board 1, a protective cover 11 is installed inside the support frame 10, a cylinder 12 is installed inside the protective cover 11, a cross bar 13 is installed on the output shaft of the cylinder 12, and an arc-shaped lower clamping plate 14 is installed at one end of the cross bar 13.

[0027] Specifically, the arc-shaped upper baffle 8 cooperates with the arc-shaped lower clamping plate 14, and the arc-shaped lower clamping plate 14 fits into the strip-shaped groove 9. The advantage is that the cooperative design of the arc-shaped upper baffle 8 and the arc-shaped lower clamping plate 14 can clamp and stabilize the coiled tubing. This clamping method can ensure that the welding object maintains a fixed position and angle during the welding process, preventing it from moving or shaking, thereby improving the welding accuracy and quality. Since the strip-shaped groove 9 opened at the top of the arc-shaped upper baffle 8 fits with the arc-shaped lower clamping plate 14, it can adapt to coiled tubing of different diameters and shapes. The arc-shaped lower clamping plate 14 can pass through the strip-shaped groove 9 to fit the outer shape of the coiled tubing, thereby providing a better clamping effect. This design makes the welding auxiliary equipment applicable to coiled tubing of various specifications, and this adjustability makes the welding auxiliary equipment more flexible and adaptable.

[0028] Specifically, the arc-shaped lower clamping plate 14 passes through the inside of the through hole 6 and is connected to one end of the cross bar 13. The advantage is that by controlling the telescopic movement of the cylinder 12, the position and clamping force of the arc-shaped lower clamping plate 14 can be conveniently adjusted. Such an automated operation simplifies the manual operation during the welding process, improves work efficiency and consistency. Installing the cylinder 12 at the bottom of the operation board 1 and allowing the arc-shaped lower clamping plate 14 to pass through the through hole 6 in the operation board 1 can effectively save space. Such a design makes the equipment more compact, reduces the floor area of the equipment, and provides more space and convenience for the working area. The cylinder 12, as a power source, has a stable power output and reliable working performance. Through appropriate design and adjustment, it can ensure that the clamping force is stable and reliable, maintaining the stable fixation of the welding object, thereby improving the welding quality and stability.

[0029] Specifically, the height of the limit plate 7 is the same as the height when the telescopic frame 4 is fully retracted into the telescopic box 2. The advantage is that, through the limiting effect of the limit plate 7, it prevents the arc-shaped lower clamping plate 14 from shrinking too much downward, which can increase the stability of the welding auxiliary equipment. When the arc-shaped lower clamping plate 14 shrinks excessively, it may cause the equipment to be unstable or tilted, thus affecting the accuracy and stability of welding. Through the limit plate 7, the stable state of the equipment can be maintained, providing a more reliable welding environment. The height of the limit plate 7 is the same as the height when the telescopic frame 4 is fully retracted into the telescopic box 2. This design makes the operation more convenient. The welder only needs to fully retract the telescopic frame 4 to the height of the limit plate 7 to ensure that the arc-shaped lower clamping plate 14 will not shrink excessively. This simplifies the operation steps, reduces the possibility of human error, and improves work efficiency.

[0030] Specifically, the elastic clamping bead 5 fits into the round hole 3 opened on one side of the telescopic box. The advantage is that, through the cooperation of the elastic clamping bead 5 and the round hole 3, the telescopic device can achieve free extension and contraction. When the device needs to extend, the elastic clamping bead 5 can easily slide through the round hole 3, allowing the extension of the telescopic frame 4. When the device needs to contract, the elastic clamping bead 5 can fit back into the round hole 3 to keep the device compact. The elastic clamping bead 5 is usually made of wear-resistant and corrosion-resistant materials, such as spring steel or stainless steel. This material has good durability and can withstand long-term use and frequent telescopic operations without being easily damaged. Therefore, the telescopic device connected by the elastic clamping bead 5 has a long service life.

[0031] Specifically, an anti-slip pad 15 is installed at the bottom of the support frame 10. The advantage is that the anti-slip pad 15 can effectively provide the friction between the support frame 10 and the ground, thereby increasing the stability of the equipment. This is very important for the safety and stability of the welding work because during the welding process, it is necessary to maintain the accurate position and stability of the coiled tubing. During the welding process, the coiled tubing may be affected by the thermal expansion of the heat-affected zone of the welding and the forces during the welding process and slide or shift. By installing the anti-slip pad 15, the risk of sliding and shifting can be effectively reduced. During the welding process, relatively large vibrations and noises may be generated. The anti-slip pad 15 has the functions of shock absorption and sound absorption, which can reduce the transmission of vibrations and noises and provide a relatively quiet and stable working environment.

[0032] In use, for the coiled tubing welding auxiliary device, the components and installation positions on the right side of the operation panel 1, as well as the working principle, are the same as those on the left side of the operation panel 1. Place the tubing to be welded on the inner wall of the arc-shaped lower clamping plate 14, and adjust the elastic bead 5. The elastic bead 5 can easily slide through the round hole 3, allowing the extension of the telescopic frame 4. Adjust the telescopic frame 4 to be at the same height as the arc-shaped lower clamping plate 14. By starting the cylinder 12, the output shaft of the cylinder 12 will push the cross bar 13, and the cross bar 13 will drive the arc-shaped lower clamping plates 14 installed at both ends to move upward. The cooperative design of the arc-shaped upper baffle 8 and the arc-shaped lower clamping plate 14 can clamp and stabilize the tubing. This clamping method can ensure that the welding object remains in a fixed position and angle during the welding process, preventing it from moving or shaking, thereby improving the welding accuracy and quality. Since the strip-shaped groove 9 opened at the top of the arc-shaped upper baffle 8 fits with the arc-shaped lower clamping plate 14, it can adapt to tubing of different diameters and shapes. The arc-shaped lower clamping plate 14 can pass through the strip-shaped groove 9 and fit with the outer shape of the tubing, thus providing a better clamping effect. This design makes the welding auxiliary equipment applicable to tubing of various specifications.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
