Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to a pipe end rotating module and its anti-corrosion layer turning device. Background Technology

[0002] With the continuous improvement of anti-corrosion coating technology for steel pipelines both domestically and internationally, the three-layer polyethylene and polypropylene anti-corrosion coating, which is currently the most widely used, has been adopted by more customers and achieved excellent results. This technology is typically applied to single branch pipes 9-24 meters long, which are then welded together on-site to form a transmission pipeline. In this configuration, the coating treatment at both ends of the single branch pipe is particularly important. Currently, a steel pipe rotary table combined with a cutting structure is mainly used to cut the anti-corrosion layer at the pipe ends. However, existing rotary tables primarily rotate the entire steel pipe, which is prone to displacement during rotation, causing changes in the position of the pipe ends and affecting the cutting effect. Utility Model Content

[0003] The purpose of this utility model is to provide a pipe end rotating module and its anti-corrosion layer turning device.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pipe end rotation module includes a base frame, a limiting vertical roller, two sets of transmission units, and a transmission motor. The rear end of the base frame has a boss that is higher than the front end. The limiting vertical roller is mounted upright and rotatably at the center of the rear end of the base frame. The two sets of transmission units are mounted on both sides of the front end of the base frame, capable of spiral transmission in the direction of the limiting vertical roller. Each transmission unit is equipped with a transmission motor. Each transmission unit is equipped with a rotatable support roller. The transmission motor drives the corresponding support roller to rotate, allowing the pipe end to fall between the support rollers of the two sets of transmission units. The support rollers support the outer circumference of the pipe end. As the transmission motor starts, the two sets of transmission units drive the steel pipe to rotate and transport it in the direction of the limiting vertical roller, providing a tendency for the steel pipe to move in the direction of the limiting vertical roller until the edge of the pipe end abuts against the limiting vertical roller. The limiting vertical roller rotates with the steel pipe, limiting the movement of the steel pipe.

[0006] In addition, it is necessary to provide a corrosion-resistant coating turning device with the aforementioned pipe end rotating module.

[0007] A corrosion-resistant coating turning device includes a main frame, a pipe end rotating module, and a corrosion-resistant coating turning module. The main frame has a base and a fixed frame vertically erected at the rear end of the base. The base has a turning station at the front end, and the pipe end rotating module is installed on the turning station. A lifting drive unit is installed at the front end of the fixed frame. The corrosion-resistant coating turning module and the pipe end rotating module are installed on the lifting drive unit in a vertically corresponding manner, and can be raised and lowered relative to the turning station under the drive of the lifting drive unit.

[0008] As a further technical solution of this utility model: the support frame is provided with a forward and backward drive cylinder at the rear end. The drive rod of the forward and backward drive cylinder is connected to the tube end rotation module, so that the drive rod of the forward and backward drive cylinder can extend and retract, thereby driving the tube end rotation module to move forward and backward on the turning station.

[0009] As a further technical solution of this utility model: the base frame is provided with two second guide rails on both sides of the turning station along the forward and backward direction of the base frame, and the base frame is provided with two second sliders on both sides of the bottom that match the two second guide rails, so that each second slider slides along the corresponding second guide rail when the base frame moves forward and backward, thereby improving stability.

[0010] As a further technical solution of this utility model: the anti-corrosion layer turning module includes an outer frame connected to the lifting drive unit, a lifting drive cylinder installed on the top of the outer frame, an inner frame that can be lifted and lowered and installed on the outer frame, a linear module installed on the inner frame, and a turning unit on the slide table on which the linear module is installed. The drive rod of the lifting drive cylinder is connected to the inner frame.

[0011] As a further technical solution of this utility model: the bottom of the inner frame is provided with a stop roller that can rotate between the front inner wall and the linear module.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model proposes a pipe end rotating module and its anti-corrosion coating turning device. Through the cooperation of the base frame, limiting roller, two sets of transmission units and transmission motor, the pipe end falls between the support rollers of the two sets of transmission units. After the support rollers support the outer circumference of the pipe end, with the start of the transmission motor, the two sets of transmission units drive the steel pipe to rotate and transport it in the direction of the limiting roller, providing a tendency for the steel pipe to move in the direction of the limiting roller until the edge of the pipe end abuts against the limiting roller. The limiting roller rotates with the rotation of the steel pipe, limiting the steel pipe and effectively preventing the steel pipe from deviating during the turning process. While ensuring the turning effect, it effectively improves the efficiency of coating treatment. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0018] Please see Figure 1 A corrosion-resistant coating turning device includes a main frame 10, a pipe end rotation module 20, and a corrosion-resistant coating turning module 30.

[0019] The main frame 10 has a base frame 11 and a fixed frame 12 vertically erected at the rear end of the base frame 11. The base frame 11 has a turning station 101 at the front end and a forward / backward drive cylinder 13 at the rear end. The tube end rotation module 20 is mounted on the turning station 101 and can move forward and backward relative to the fixed frame 12. The drive rod of the forward / backward drive cylinder 13 is connected to the tube end rotation module 20, so that the drive rod of the forward / backward drive cylinder 13 can extend and retract, thereby driving the tube end rotation module 20 to move forward and backward on the turning station 101. The fixed frame 12 has a lifting drive unit 14 installed at the front end. The anti-corrosion layer turning module 30 and the tube end rotation module 20 are mounted on the lifting drive unit 14 in a vertically corresponding manner. Under the drive of the lifting drive unit 14, it can move up and down relative to the turning station 101.

[0020] The tube end rotation module 20 includes a base frame 21 connected to the drive rod of the forward / backward drive cylinder 13, a limiting vertical roller 22 mounted at the rear center of the base frame 21 capable of upright rotation, two sets of transmission units 23 mounted on both sides of the front end of the base frame 21 for helical transmission in the direction of the limiting vertical roller 22, and a transmission motor 24 mounted on any of the transmission units 23. The rear end of the base frame 21 is a boss with a height higher than the front end, so that the limiting vertical roller 22 is positioned above the two sets of transmission units 23; each transmission unit 23 The upper part is equipped with a rotatable roller 231. The transmission motor 24 is used to drive the roller 231 of the corresponding transmission unit 23 to rotate, so that the end of the steel pipe falls between the rollers 231 of the two sets of transmission units 23. The roller 231 supports the outer circumference of the end of the pipe. With the start of the transmission motor 24, the two sets of transmission units 23 drive the steel pipe to rotate, providing the steel pipe with the tendency to move in the direction of the limiting roller 22 until the edge of the pipe end abuts against the limiting roller 22. The limiting roller 22 rotates with the steel pipe to limit the steel pipe.

[0021] The anti-corrosion layer turning module 30 includes an outer frame 31 connected to the lifting drive unit 14, a lifting drive cylinder 32 mounted on the top of the outer frame 31, an inner frame 33 that can be raised and lowered relative to the turning station 101 and extends from the bottom of the outer frame 31 and is installed inside the outer frame 31, a linear module 34 mounted on the inner frame 33, and a turning unit 35 mounted on a slide table 341 on which the linear module 34 is mounted. The drive rod of the lifting drive cylinder 32 is connected to the inner frame 33, allowing the drive rod of the lifting drive cylinder 32 to extend and retract. The inner frame 33 is raised and lowered relative to the turning station 101. The turning unit 35 includes a base 351 connected to the slide table 341, a tool extension drive cylinder 352 installed on the top of the base 351, and a turning tool holder 353 that can be raised and lowered and is located below the tool extension drive cylinder 352. The drive rod of the tool extension drive cylinder 352 is connected to the top of the turning tool holder 353, so that the drive rod of the tool extension drive cylinder 352 extends out and drives the cutting edge 301 of the turning tool holder 353 to pass through the bottom of the inner frame 33.

[0022] Understandably, the method of using the anti-corrosion coating turning device includes the following steps: First, under the action of a matching transmission frame, the end of the steel pipe to be processed extends onto the anti-corrosion coating turning device. The end of the pipe falls between the rollers 231 of the two sets of transmission units 23. The rollers 231 support the outer circumference of the end of the pipe. With the start of the transmission motor 24, the two sets of transmission units 23 drive the linear module 34, providing a tendency for the steel pipe to move in the direction of the limiting vertical roller 22 until the edge of the pipe end abuts against the limiting vertical roller 22. The limiting vertical roller 22 rotates with the steel pipe, limiting the steel pipe; Second, the linear module... The drive slide 341 moves to the initial position. The lifting drive unit 14 drives the outer frame 31 to descend, and the drive rod of the lifting drive cylinder 32 extends and retracts, causing the inner frame 33 to rise and fall. This moves the turning unit 35 to a preset position. As the steel pipe rotates, the drive rod of the tool extension drive cylinder 352 extends, driving the cutting edge 301 of the turning tool holder 353 to turn the anti-corrosion layer on the pipe end. In the third step, the linear module 34 drives the slide 341 to move from the initial position within a preset range. During this movement, the height of the cutting edge 301 can be adjusted by the lifting drive cylinder 32 and the tool extension drive cylinder 352 to turn the anti-corrosion layer into the required shape. In this way, the turning of the anti-corrosion layer on the end of the steel pipe is completed efficiently.

[0023] Furthermore, in this embodiment, the bottom of the inner frame 33 is provided with a rotatable abutment roller 36 between the front inner wall and the linear module 34. The lifting drive unit 14 drives the outer frame 31 to descend and the drive rod of the lifting drive cylinder 32 extends and retracts to drive the inner frame 33 to rise and fall. The abutment roller 36 can abut against the outer periphery of the pipe end and rotate with the steel pipe, thereby improving the stability of the anti-corrosion layer of the steel pipe end during machining.

[0024] Furthermore, in this embodiment, the lifting drive unit 14 includes a lifting drive motor 141 mounted on the top of the fixed frame 12, a drive screw 142 erected at the front end of the fixed frame 12 and rotatable under the drive of the lifting drive motor 141, and a screw sleeve 143 passing through the drive screw 142. The screw sleeve 143 is connected to the bottom of the outer frame 31, so that when the lifting drive motor 141 drives the drive screw 142 to rotate, the screw sleeve 143 rotates with the drive screw 142, thereby driving the outer frame 31 to rise and fall.

[0025] Furthermore, in this embodiment, the fixing frame 12 is provided with a first guide rail 121 at the front end that is parallel to the drive screw 142, and the outer frame 31 is provided with a first slider 311 at the rear end that matches the first guide rail 121. When the lifting drive unit 14 drives the outer frame 31 to lift, the first slider 311 slides along the first guide rail 121 to improve the stability of the outer frame 31 when lifting.

[0026] Furthermore, in this embodiment, the interior of the outer frame 31 is provided with a partition 312 between the front and rear ends, which forms a front cavity through which the inner frame 33 passes and a rear cavity through which the drive screw 142 passes and is connected to the screw sleeve 143.

[0027] Furthermore, in this embodiment, the outer frame 31 has a protruding strip 313 on the front inner wall and the side of the partition 312 facing the front cavity along the lifting direction of the inner frame 33. The front and rear adjacent protruding strips 313 of the inner frame 33 are recessed with grooves 331, so that the protruding strips 313 can pass into the corresponding grooves 331. When the inner frame 33 is lifted and lowered by the extension and retraction of the drive rod of the lifting drive cylinder 32, the stability of the lifting of the inner frame 33 is improved.

[0028] Furthermore, in this embodiment, the base frame 11 is provided with two second guide rails on both sides of the turning station 101 along the forward and backward direction of the base frame 21. The base frame 21 is provided with two second sliders on both sides of the bottom that match the two second guide rails. When the forward and backward drive cylinder 13 drives the base frame 21 to move forward and backward, each second slider slides along the corresponding second guide rail, thereby improving the stability of the base frame 21 when moving forward and backward.

[0029] Furthermore, in this embodiment, the base 351 is provided with two guide strips 37 on both sides of the bottom of the front end face, and the rear end of the turning tool holder 353 is inserted between the two guide strips 37 to ensure the stability of the turning tool holder 353 when the drive rod of the tool drive cylinder 352 drives the turning tool holder 353 to rise and fall.

[0030] In summary, this utility model provides a pipe end rotating module and its anti-corrosion coating turning device. Through the cooperation of the base frame 21, the limiting roller 22, the two sets of transmission units 23, and the transmission motor 24, the pipe end falls between the support rollers 231 of the two sets of transmission units 23. After the support rollers 231 support the outer circumference of the pipe end, with the start of the transmission motor 24, the two sets of transmission units 23 drive the steel pipe to rotate and be conveyed in the direction of the limiting roller 22, providing a tendency for the steel pipe to move in the direction of the limiting roller 22 until the edge of the pipe end abuts against the limiting roller 22. The limiting roller 22 rotates with the steel pipe, limiting the steel pipe and effectively preventing the steel pipe from deviating during the turning process. This ensures the turning effect while effectively improving the coating treatment efficiency.
