Description

Technical Field

[0001] This invention belongs to the field of pipeline welding technology, specifically relating to a welding equipment for insulated pipelines used in electromechanical engineering. Background Technology

[0002] Insulated pipes are typically used in electromechanical engineering to transport liquids or gases. They are specially designed to reduce heat loss or prevent overheating or undercooling of the pipe surface. The main functions of insulated pipes are energy saving, preventing temperature loss of the medium, improving transportation efficiency, and protecting the pipe itself from the influence of the external environment.

[0003] The structure of insulated pipes typically includes the following parts: an inner pipe (the pipe for transporting the medium), responsible for conveying liquids or gases, the material of which depends on the properties of the medium being transported, and is usually a metal; an insulation layer, located outside the inner pipe, used to reduce heat conduction and loss, the insulation material is usually polyurethane, rock wool, aluminum silicate fiber, etc., which have good insulation performance and durability; a waterproof layer (optional), sometimes a waterproof material is added outside the insulation layer to prevent moisture from the external environment from penetrating the insulation layer and affecting the insulation effect; and an outer sheath, covering the waterproof layer or insulation layer, used to protect the pipe from mechanical damage, ultraviolet radiation, or chemical corrosion, usually made of metal or polyethylene.

[0004] Insulated pipes have a wide range of applications, especially in electromechanical engineering applications requiring long-distance transport of high-temperature or low-temperature media, such as petrochemical, heating, and refrigeration systems. Choosing suitable insulated pipes can significantly improve energy efficiency and reduce energy consumption and operating costs.

[0005] In the production of insulated pipes, the inner pipes need to be welded together. In the existing technology, before welding two pipes, a hand-operated hoist or other lifting structure is needed to place the pipes on the fixture, align the welding positions, and then weld them. After welding, the pipes are removed from the fixture. This processing method is inefficient and has a low degree of mechanization. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cleaning equipment for anchor chains of large ships with high cleaning efficiency and thorough cleaning.

[0007] The technical solution adopted to solve the above technical problems is: a welding equipment for insulated pipes in electromechanical engineering, including two symmetrically arranged pipe support frames and a pipe to be welded arranged between the pipe support frames. The two pipe support frames are arranged in a "Y" shape, and two power adjustment rollers for rotating the pipe to be welded are arranged between the two pipe support frames. A pipe pressing structure for pressing the pipe to be welded is provided on one side of the two power adjustment rollers.

[0008] Through the above technical solutions, the pipe lifting frame can lift the pipes to be welded, making it convenient to weld and fix the two pipes to be welded. The power adjustment roller realizes the self-rotation adjustment of the pipes to be welded, so that the welding position of the pipes to be welded is adjusted, and the welding is free of dead angles. The pipe pressing structure presses down on the pipes to be welded, preventing the pipes to be welded from shifting during rotation and causing welding deviation.

[0009] Both of the aforementioned power adjustment rollers include two symmetrically arranged drive outer sleeves. The inner sides of the two drive outer sleeves, at their far ends, are rotatably connected to a fixed sleeve. The inner sides of the two drive outer sleeves, at their close ends, are rotatably connected to a linkage sleeve. A dual-axis motor is fixedly connected to the inner wall of the linkage sleeve via a support frame. Both drive ends of the dual-axis motor are fixedly connected to drive shafts, and the drive shafts are rotatably connected to the fixed sleeves.

[0010] Through the above technical solution, the drive outer sleeve can rotate, providing power for the rotation of the pipe to be welded. The fixed sleeve can support the drive outer sleeve, and the power adjustment roller is connected to the pipe support frame through the fixed sleeve. The dual-axis motor provides power to the drive shaft, and the rotatable connection between the drive shaft and the fixed sleeve can support the drive shaft and the linkage sleeve.

[0011] Furthermore, a power groove is provided on the inner wall of the drive outer sleeve near the linkage sleeve. An internal gear ring is embedded and fixedly connected to the inner wall of the power groove. Drive gears are fixedly connected through the outer walls of the two drive shafts. The drive gears are connected to the corresponding internal gear rings by gear meshing. The pipe to be welded rolls with the outer wall of the drive outer sleeve. The end of the fixed sleeve away from the dual-axis motor is fixedly connected to the corresponding pipe support frame.

[0012] The above technical solution allows for the fixed installation of the internal gear ring by setting a power groove, and the drive shaft provides power to the drive gear, which then transmits the power to the position of the internal gear ring, causing the outer sleeve to rotate.

[0013] Furthermore, the pipe pressing structure includes a spring frame, a lifting plate is fixedly connected to the side of the spring frame away from the pipe support frame, the two corners below the lifting plate are rounded, an elastic block is slidably connected to the inner wall of the spring frame, and a number of evenly distributed compression springs are fixedly connected between the lower surface of the elastic block and the bottom wall of the inner wall of the spring frame.

[0014] Through the above technical solution, the spring frame can achieve sliding limit of the elastic block, and the two corners below the lifting plate are set in an arc shape, which can cooperate with the bidirectional cam to move upward, thereby releasing the pressure on the pipe to be welded. When rotating the pipe lifting frame, the pipe to be welded can be put down to achieve unloading, and the spring is pressed to make the elastic block press down.

[0015] Furthermore, a clamping shaft is rotatably connected to the middle of the side of the elastic block near the pipe support frame, and a balance bar is fixedly connected to the side of the elastic block near the clamping shaft and above the clamping shaft. The end of the balance bar away from the elastic block is rotatably connected to the end of the clamping shaft away from the elastic block.

[0016] Through the above technical solution, when the elastic block presses down, the clamping shaft can fully act on the pipe to be welded, avoiding the problem of poor welding quality caused by the pipe being misaligned during welding. The balance bar can assist in supporting the clamping shaft and prevent the end of the clamping shaft away from the elastic block from being deformed due to force.

[0017] Furthermore, a clamping groove is fixedly connected between the two pipe support brackets, a drive screw is rotatably connected between the two parallel inner walls of the clamping groove, two symmetrically arranged limit rods are fixedly connected to the two parallel inner walls of the clamping groove on both sides of the drive screw, and two symmetrically arranged clamping slide plates are slidably connected to the inner wall of the clamping groove.

[0018] Furthermore, a lead screw nut is fixed through the clamping slide plate, and the lead screw nut is engaged with the drive lead screw. The clamping slide plate is slidably connected to the limiting rod. The two clamping slide plates are located on both sides of the two pipes to be welded. A support plate is fixedly connected to the side wall of the pipe support frame on the side away from the pipe pressing structure. A drive motor is fixedly connected to the surface of the support plate. The drive end of the drive motor is fixedly connected to the end face of the drive lead screw.

[0019] The above technical solution involves starting the drive motor, which provides power to the drive screw, causing the clamping slide to move under the action of the limit rod. The drive screw is a bidirectional screw, which causes the two clamping slides to move towards each other or relative to each other, pushing the two pipes to be welded towards the center position, so that the weld seam is aligned with the center position of the power groove, thus achieving automatic positioning.

[0020] Furthermore, two symmetrically arranged support plates are fixedly connected to the surface of the spindle box base. A power shaft is rotatably connected to the side of each support plate that is far apart from each other. The corresponding power shaft is connected to the spindle box drive end of the spindle box base. The two power shafts are fixedly connected to the corresponding pipe support brackets through the spindle box base. Two symmetrically arranged lifting arc plates are fixedly connected to the inner wall of the spindle box base. The bottom of the two pipe support brackets is rotatably connected to the inner side of the lifting arc plates.

[0021] Through the above technical solution, the support plate supports the power shaft, the power shaft adjusts the rotation of the pipe lifting frame, and the lifting arc plate lifts the bottom of the pipe lifting frame, making the pipe lifting frame more stable in use.

[0022] Furthermore, a welding support platform is fixedly connected to the middle of the side walls of the two pipe support brackets, an electric slide rail is fixedly connected to the upper surface of the welding support platform, a mounting base is fixedly connected to the slide seat of the electric slide rail, and a welding robot is fixedly mounted on the surface of the mounting base.

[0023] Through the above technical solution, the welding support platform can achieve fixed installation of electric slide rails, thereby adjusting the position of the welding robot and controlling the welding position.

[0024] Furthermore, the power shaft on the side away from the drive end of the spindle box passes through the spindle box seat and is fixedly connected to a bidirectional cam. An elastic groove is provided on the side wall of the spindle box seat above the bidirectional cam. A linkage slide plate is slidably connected to the inner wall of the elastic groove. A tension spring is fixedly connected between the lower surface of the linkage slide plate and the bottom wall of the elastic groove. The linkage slide plate is fixedly connected to the side wall of the lifting plate of the pipe pressing structure.

[0025] Through the above technical solution, the bidirectional cam can adjust the height of the pipe pressing structure, thereby pressing or releasing the pipe to be welded, and the pipe pressing structure is fully pressed down under the action of the tension spring.

[0026] The beneficial effects of the present invention are as follows: (1) By setting up a pipe lifting frame and a power adjusting roller, the pipe lifting frame will flip to both sides during actual operation, so as to receive the pipe to be welded conveyed by the conveyor belt, or to put down the pipe to be welded after welding. The whole process is highly mechanized, and no additional lifting structure is required, which saves equipment investment costs and eliminates the lifting process, thus improving the welding efficiency of the pipe. By setting up a power adjusting roller, the power adjusting roller is driven by the outer sleeve to rotate, which can realize the synchronous rotation of two pipes to be welded, so that the weld joint can be made more efficient. (1) The position is kept in synchronous rotation to achieve welding of the ring weld joint without dead angle; (2) By setting up a power groove, clamping slide plate and pipe pressing structure, the two power adjustment rollers can align the two pipes to be welded, and the two clamping slide plates can push the two pipes to be welded to the middle position so that the two pipes to be welded are merged. Then the weld is located in the middle position of the power groove. There is no need to use special clamps for alignment, which makes the welding quality higher. Under the action of the pipe pressing structure, the alignment is more stable and avoids the pipes to be welded from slipping and causing self-rotation offset, which affects the welding quality.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figure 1-7 As shown, this embodiment of a welding equipment for insulated pipes in electromechanical engineering includes two symmetrically arranged pipe support frames 9 disposed inside the spindle housing 1 and a pipe 7 to be welded disposed between the pipe support frames 9. Both pipe support frames 9 are arranged in a "Y" shape. The pipe support frames 9 can lift the pipe 7 to be welded, making it convenient to weld and fix the two pipes 7 to be welded.

[0031] Two symmetrically arranged support plates 13 are fixedly connected to the surface of the spindle box base 1. A power shaft 12 is rotatably connected to the side of the two support plates 13 that is far apart from each other. The corresponding power shaft 12 is connected to the spindle box drive end of the spindle box base 1. The two power shafts 12 are fixedly connected to the corresponding pipe support frame 9 through the shaft. Two symmetrically arranged lifting arc plates 11 are fixedly connected to the inner wall of the spindle box base 1. The bottom of the two pipe support frames 9 is rotatably connected to the inner side of the lifting arc plates 11. The support plates 13 support the power shafts 12, and the power shafts adjust the rotation of the pipe support frame 9. The lifting arc plates 11 can lift the bottom of the pipe support frame 9, making the pipe support frame 9 more stable in use.

[0032] Welding support platform 2 is fixedly connected to the middle of the side wall of the two pipe support brackets 9. Electric slide rail 3 is fixedly connected to the upper surface of the welding support platform 2. Mounting seat 4 is fixedly connected to the slide seat of the electric slide rail 3. Welding robot 5 is fixedly mounted on the surface of the mounting seat 4. The welding support platform 2 can fix the electric slide rail 3, so that the position of the welding robot 5 can be adjusted, thereby controlling the welding position.

[0033] A power shaft 12, located away from the drive end of the spindle box, passes through the spindle box seat 1 and is fixedly connected to a bidirectional cam 10. A spring groove 19 is provided on the side wall of the spindle box seat 1 above the bidirectional cam 10. A linkage slide plate 20 is slidably connected to the inner wall of the spring groove 19. A tension spring 21 is fixedly connected between the lower surface of the linkage slide plate 20 and the inner bottom wall of the spring groove 19. The linkage slide plate 20 is fixedly connected to the side wall of the lifting plate 80 of the pipe pressing structure 8. The bidirectional cam 10 can adjust the height of the pipe pressing structure 8, thereby pressing or releasing the pipe 7 to be welded. Under the action of the tension spring 21, the pipe pressing structure 8 is fully pressed down.

[0034] A clamping groove 14 is fixedly connected between the two pipe support brackets 9. A drive screw 17 is rotatably connected between the two parallel inner walls of the clamping groove 14. Two symmetrically arranged limit rods 18 are fixedly connected to the two parallel inner walls of the clamping groove 14 on both sides of the drive screw 17. Two symmetrically arranged clamping slide plates 16 are slidably connected to the inner wall of the clamping groove 14.

[0035] A screw nut is fixedly inserted through the clamping slide plate 16, and the screw nut is engaged with the drive screw 17. The clamping slide plate 16 is slidably connected to the limiting rod 18. The two clamping slide plates 16 are located on both sides of the two pipes 7 to be welded. A support plate 22 is fixedly connected to the side wall of the pipe support frame 9 on the side away from the pipe pressing structure 8. A drive motor 15 is fixedly connected to the surface of the support plate 22. The drive end of the drive motor 15 is fixedly connected to the end face of the drive screw 17. When the drive motor 15 is started, it provides power to the drive screw 17, causing the clamping slide plate 16 to move under the action of the limiting rod 18. The drive screw 17 is a bidirectional screw, which causes the two clamping slide plates 16 to move towards each other or relative to each other, pushing the two pipes 7 to be welded towards the center, so that the weld seam is aligned with the center of the power groove 14, achieving automatic positioning.

[0036] Furthermore, two power adjusting rollers 6 are installed between the two pipe support frames 9 to allow the pipe 7 to be welded to rotate. The power adjusting rollers 6 adjust the rotation of the pipe 7 to be welded, thereby adjusting the welding position of the pipe 7 to be welded and ensuring that there are no dead angles in the welding. Each of the two power adjusting rollers 6 includes two symmetrically arranged drive outer sleeves 61. The inner sides of the two drive outer sleeves 61 and the ends that are far apart from each other are rotatably connected to fixed sleeves 60. The inner sides of the two drive outer sleeves 61 and the ends that are close to each other are rotatably connected to a linkage sleeve 66. The inner wall of the linkage sleeve 66 is fixedly connected by a support frame. A dual-axis motor 64 is connected, and each of the two drive ends of the dual-axis motor 64 is fixedly connected to a drive shaft 63. The drive shaft 63 is rotatably connected to a fixed sleeve 60, which drives the outer sleeve 61 to rotate, providing power for the rotation of the pipe 7 to be welded. The fixed sleeve 60 can support the drive outer sleeve 61, and the power adjusting roller 6 is connected to the pipe support frame 9 through the fixed sleeve 60. The dual-axis motor 64 provides power to the drive shaft 63, and the rotatable connection between the drive shaft 63 and the fixed sleeve 60 can support the drive shaft 63 and the linkage sleeve 66.

[0037] A power groove 67 is provided on the inner wall of the drive outer sleeve 61 near the linkage sleeve 66. An internal gear ring 62 is embedded and fixedly connected to the inner wall of the power groove 67. Drive gears 65 are fixedly connected through the outer walls of the two drive shafts 63. The drive gears 65 are meshed with the corresponding internal gear rings 62. The pipe 7 to be welded rolls against the outer wall of the drive outer sleeve 61. The end of the fixed sleeve 60 away from the dual-shaft motor 64 is fixedly connected to the corresponding pipe support frame 9. By setting the power groove 67, the internal gear ring 62 can be fixedly installed, and the drive shaft 63 provides power to the drive gear 65, so that the drive gear 65 transmits power to the position of the internal gear ring 62, causing the drive outer sleeve 61 to rotate.

[0038] Two power adjusting rollers 6 are provided with a pipe pressing structure 8 on one side for pressing the pipe 7 to be welded. The pipe pressing structure 8 presses the pipe 7 to be welded to prevent it from shifting during rotation, which would cause welding deviation. The pipe pressing structure 8 includes a spring frame 81. A lifting plate 80 is fixedly connected to the side of the spring frame 81 away from the pipe support frame 9. The two corners below the lifting plate 80 are rounded. An elastic block 83 is slidably connected to the inner wall of the spring frame 81. Several evenly distributed compression springs 82 are fixedly connected between the lower surface of the elastic block 83 and the inner bottom wall of the spring frame 81. The spring frame 81 can slide and limit the elastic block 83. The two corners below the lifting plate 80 are rounded and can move upward in cooperation with the bidirectional cam 10, which can release the pressure on the pipe 7 to be welded. When the pipe support frame 9 is rotated, the pipe 7 to be welded can be lowered to achieve unloading. The compression springs 82 press the elastic block 83 downward.

[0039] A clamping shaft 85 is rotatably connected to the middle of the elastic block 83 near the pipe support frame 9. A balance bar 84 is fixedly connected to the side of the elastic block 83 near the clamping shaft 85 and above the clamping shaft 85. The end of the balance bar 84 away from the elastic block 83 is rotatably connected to the end of the clamping shaft 85 away from the elastic block 83. When the elastic block 83 is pressed down, the clamping shaft 85 fully acts on the pipe 7 to be welded, avoiding the problem of poor welding quality caused by the pipe 7 being misaligned during welding. The balance bar 84 can assist in supporting the clamping shaft 85 and prevent the end of the clamping shaft 85 away from the elastic block 83 from being deformed by force.

[0040] The working principle of this embodiment is as follows: The conveyor belt for transporting the pipe is set on the side of the device away from the welding robot 5. The power source in the spindle box of the spindle box 1 is started, so that the power shaft 12 drives the pipe lifting frame 9 to flip to the side of the conveyor belt. Under the action of the power shaft 12, the bidirectional cam 10 rotates to lift the lifting plate 80, so that the pipe pressing structure 8 moves upward as a whole, so as to avoid affecting the reception of the pipe 7 to be welded. The pipe 7 to be welded, which is conveyed from the conveyor belt position, is conveyed between the two power adjustment rollers 6. The rotating shaft 12 is adjusted in the opposite direction, so that the pipe lifting frame 9 is reset, and the bidirectional cam 10 no longer controls the lifting plate 80. The entire pipe pressing structure 8 moves downward under the action of the linkage slide plate 20 and the tension spring 21. Under the action of the pressure spring 82, the pressure shaft 85 presses the pipe 7 to be welded fully at the position of the power adjustment roller 6. Start the drive motor 15 to power the drive screw 17. The clamping slider 16 moves synchronously under the action of the drive screw 17 and the limit rod 18, squeezing the two pipes 7 to be welded into the middle of the power groove 14, so that the two welding pipes 7 contact and complete the alignment.

[0041] Start the dual-axis motor 64, so that the drive outer sleeve 61 keeps rotating under the action of the drive gear 65 and the internal gear ring 62, so that the start of the outer sleeve 61 drives the two pipes 7 to be welded to rotate synchronously, so that the weld position of the two pipes 7 to be welded is welded and fixed by the welding robot 5. After welding is completed, the welding robot 5 is moved to one side of the welding support platform 2, and this side is outside the reset area of ​​the pipe 7 to be welded. Then the power source in the spindle box of the spindle box seat 1 is started, so that the power shaft 12 drives the pipe lifting frame 9 to flip to one side of the welding support platform 2. The drive motor 15 is started, so that the clamping slide plate 16 moves to both sides, and the welded pipe 7 to be welded rolls down from the position of the power adjustment roller 6.
