Description

Technical Field

[0001] This utility model belongs to the technical field of steel pipe dent repair equipment, specifically relating to a steel pipe dent repair equipment. Background Technology

[0002] In the field of power infrastructure construction, with the continuous expansion of ultra-high voltage transmission networks, the large-scale construction of urban underground integrated pipe corridors, and the comprehensive advancement of smart grid transformation projects, higher requirements have been placed on the stability, safety, and durability of power transmission systems. Thin-walled steel pipes, as a key material for power conduits, have become a core component in power product production lines due to their excellent mechanical properties and electrical insulation.

[0003] In actual production, taking a 3-meter-long thin-walled steel pipe as an example, due to its long length and thin wall, it is very easy for the steel pipe to develop pit defects due to mechanical collisions, vibrations and frictions during automated transmission, multi-station processing and finished product transfer and unloading in the production line. According to industry survey data, the proportion of such pitted pipes in the current power product production line is generally as high as 20% to 50%, and the proportion is even higher in some production lines with complex processes.

[0004] Currently, the traditional methods for repairing dents in steel pipes mainly rely on manual repair or simple mechanical repair. Manual repair involves operators using hammers or molds to correct the dents. This method is not only labor-intensive and inefficient, but the repair results are also significantly affected by the operator's experience and skill level, making it difficult to guarantee the consistency of repair accuracy and quality. Although simple mechanical repair equipment improves repair efficiency to some extent, its simple structural design and low degree of automation make it impossible to accurately control the repair force and stroke. This can easily cause secondary damage to the steel pipe during the repair process, or even lead to the scrapping of the steel pipe. At the same time, it is difficult to meet the needs of large-scale, standardized production.

[0005] Therefore, a steel pipe dent repair device was designed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 As shown;

[0024] A device for repairing dents in steel pipes includes a main body 1.

[0025] In this implementation plan: Currently, the traditional methods for repairing dents in steel pipes mainly rely on manual repair or simple mechanical repair. Manual repair involves operators using hammers or molds to correct the dents. This method is not only labor-intensive and inefficient, but the repair effect is also significantly affected by the operator's experience and skill level, making it difficult to guarantee the consistency of repair accuracy and quality. Although simple mechanical repair equipment improves repair efficiency to some extent, its simple structural design and low degree of automation make it impossible to accurately control the repair force and stroke, which can easily cause secondary damage to the steel pipe during the repair process, or even lead to the scrapping of the steel pipe. At the same time, it is difficult to meet the needs of large-scale, standardized production. In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a dent repair system 2 and a hydraulic system 7 are added to this application.

[0026] Furthermore:

[0027] like Figure 1 As shown:

[0028] Based on the above: a steel pipe dent repair device, further comprising a dent repair system 2 disposed on the surface of the main body 1;

[0029] The dent repair system 2 includes a frame 3 set on the surface of the body 1. A positioning cylinder 4 is installed at one end of the frame 3. A positioning mold 41 that cooperates with the body 1 is installed on the push rod at the end of the positioning cylinder 4. An inserting cylinder 5 is installed at the end of the surface of the frame 3 away from the positioning cylinder 4. An inserting mold 51 that cooperates with the body 1 is installed on the push rod at the end of the inserting cylinder 5.

[0030] In this implementation plan: the frame 3 serves as the basic load-bearing structure, providing support for the entire pit repair system 2. When it is necessary to repair the pit on the surface of the body 1, the operator first places the body 1 in a suitable position on the surface of the frame 3. Then, the end of the body 1 is engaged with the positioning mold 41 to position the body 1 and restrict its movement during the repair process. The positioning cylinder 4 is activated to move the body 1 to a suitable position through the positioning mold 41. Then, the push-in cylinder 5 is activated to push the push-in mold 51 into the body 1 through the push rod. Under the action of the push-in cylinder 5, the push-in mold 51 pushes the pit on the body 1 outward. This process achieves pit repair. Throughout the process, two hydraulic cylinders work together to apply force to the body 1 through the mold, completing the repair operation. After the body 1 is repaired, the positioning hydraulic cylinder 4 operates to drive the positioning mold 41 away from the surface of the body 1. Then, the worker removes the ejector mold 51, and then the ejector cylinder 5 operates to make the ejector rod retract from the interior of the body 1, so that the body 1 is freed from the control of the positioning hydraulic cylinder 4 and the ejector cylinder 5. This design, with the cooperation of the positioning hydraulic cylinder 4 and the ejector cylinder 5, enables the repair operation to be effectively implemented, improves the accuracy and reliability of the repair, and lays the foundation for achieving efficient repair of pits on the body 1.

[0031] Furthermore:

[0032] In an optional embodiment, a placement plate 31 that mates with the surface of the body 1 is fixedly connected to the surface of the rack 3, and the body 1 is placed on the surface of the rack 3 via the placement plate 31.

[0033] In this embodiment: the placement plate 31 is fixed on the surface of the frame 3, and its placement surface is adapted to the surface of the body 1. Before the repair operation, the operator places the body 1 on the placement plate 31. The placement plate 31 provides a stable placement plane for the body 1, so that the body 1 can be quickly and accurately placed in the repair position, which facilitates the subsequent operation of the positioning cylinder 4 and the jacking cylinder 5. At the same time, the placement plate 31 can also bear the weight of the body 1 to a certain extent, reducing the stress on other parts of the frame 3. The setting of the placement plate 31 simplifies the placement process of the body 1, improves the feeding efficiency, reduces the time for the operator to find a suitable placement position, and further enhances the stability of the body 1 in the repair process through good cooperation with the surface of the body 1, reduces the risk of repair deviation caused by improper placement of the body 1, and ensures the smooth progress and repair quality of the repair work.

[0034] Furthermore:

[0035] In an optional embodiment, a clamping fixture 6 is mounted on the surface of the frame 3.

[0036] In this embodiment: the clamping fixture 6 is installed on the surface of the frame 3. After the body 1 is placed on the placement plate 31 and the initial positioning is completed, the clamping fixture 6 is activated to clamp the body 1, ensuring that the body 1 cannot be displaced during the repair process. This allows the body 1 to remain fixed when the positioning cylinder 4 and the ejection cylinder 5 are working, so that the ejection mold 51 can accurately repair the pit. This effectively prevents the body 1 from moving due to force, avoids repair failure or secondary damage caused by changes in the position of the body 1 during the repair process, and improves the repair success rate and repair quality.

[0037] Furthermore:

[0038] In an optional embodiment, a hydraulic system 7 is also included, disposed on the surface of the body 1;

[0039] The hydraulic system 7 includes a hydraulic station 8 disposed on the surface of the frame 3.

[0040] In this embodiment: the hydraulic system 7 serves as the power source for the equipment, and the hydraulic station 8 is installed on the surface of the frame 3 to provide power to the positioning cylinder 4 and the jacking cylinder 5, thereby enabling the positioning cylinder 4 to push the positioning mold 41 and the jacking cylinder 5 to push the jacking mold 51. During this process, the hydraulic station 8 can precisely adjust the output hydraulic oil pressure and flow rate, thereby precisely controlling the action pressure and stroke of the positioning cylinder 4 and the jacking cylinder 5 to meet the needs of different repair conditions.

[0041] It should be noted that the hydraulic pump in the hydraulic station 8 draws hydraulic oil from the oil tank, pressurizes it, and then delivers it to the positioning cylinder 4 and the jacking cylinder 5 through pipelines. The pressure of the hydraulic oil pushes the piston in the cylinder, which in turn drives the jacking rod to move.

[0042] Furthermore:

[0043] In an optional embodiment, the surface of the hydraulic station 8 is provided with an electrical control box 9.

[0044] In this embodiment, the electrical control box 9 is the control center of the equipment. It can achieve precise control of components such as the positioning cylinder 4, the jacking cylinder 5, and the clamping fixture 6, such as starting, stopping, speed adjustment, and thrust magnitude. The presence of the electrical control box 9 enables intelligent and automated control of the entire repair equipment. Operators do not need to manually adjust the complex mechanical structure. They can complete the repair parameter setting and equipment operation control through simple operations, reducing the difficulty of operation and labor intensity.

[0045] It should be noted that the electrical control box 9 integrates various electrical control components and control systems. Operators input repair commands and parameters through the operation interface on the electrical control box 9, such as buttons and displays. According to the preset program and input commands, the electrical control box 9 sends electrical signals to the electrical components in the hydraulic station 8, such as solenoid valves and motor drivers, to control the flow direction, pressure and flow rate of hydraulic oil, thereby precisely controlling the actions of the positioning cylinder 4 and the jacking cylinder 5.

[0046] Working principle: The operator first places the body 1 on the placement plate 31, which provides a stable placement surface for the body 1. Then, the end of the body 1 is engaged with the positioning mold 41 to position the body 1 and restrict its movement during the repair process. The operator manually activates the control box 9 to start the hydraulic station 8, which initiates the operation of the positioning cylinder 4. The positioning cylinder 4 moves the body 1 to the appropriate position through the positioning mold 41. Then, the clamping fixture 6 is activated to clamp the body 1, ensuring that the body 1 cannot move during the repair process. After the position of the body 1 is fixed, the push-in cylinder 5 is activated to push the push-in mold 51 into the body 1 through the push rod. Under the action of the jacking cylinder 5, the dent in the body 1 is pushed outward to repair the dent. During the entire process, the two cylinders work together to apply force to the body 1 through the mold to complete the repair operation. After the body 1 is repaired, the positioning cylinder 4 drives the positioning mold 41 to move away from the surface of the body 1. Then, the worker takes out the jacking mold 51. Then, the jacking cylinder 5 works to make the push rod move away from the inside of the body 1. After the body 1 is freed from the control of the positioning cylinder 4 and the jacking cylinder 5, the clamping fixture 6 is released, and the shaped body 1 can be taken out. This design, with the cooperation of the positioning cylinder 4 and the jacking cylinder 5, enables the repair operation to be effectively implemented and improves the accuracy and reliability of the repair.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
