Description

Technical Field

[0001] This invention relates to the field of new energy welding vehicle technology, specifically a new energy electric-powered welding vehicle. Background Technology

[0002] A welding vehicle, also known as a welding power supply workstation vehicle, is essentially a mobile platform that integrates the core equipment required for welding operations. During welding, manual, semi-automatic, and fully automatic welding equipment are retrieved from the welding vehicle. When using manual welding equipment, welding rods need to be changed manually. Traditionally, changing welding rods requires the welder to stop welding, manually knock off the rod end, remove the new rod from the insulation container, and then load and clamp it into the welding clamp. This process is cumbersome, time-consuming, and requires the welder to handle the hot rod tip and potentially hot clamping jaws with bare hands or while wearing heavy gloves, posing a risk of burns and making the operation inconvenient.

[0012] This invention provides a welding vehicle powered by a new energy electric drive, which has the following beneficial effects:

[0013] 1. In existing technologies, replacing welding rods in this new energy electric-powered welding vehicle requires the welder to stop welding, manually knock off the electrode head, remove the new electrode from the insulation cylinder, and then load and clamp it in the welding clamp. This process is cumbersome and time-consuming. This invention, through a pressure lever drive mechanism integrated into the handle, achieves one-button, semi-automatic electrode replacement. During welding breaks, the welder only needs to hold and press the pressure lever with one hand to automatically complete a series of actions, including pushing the new electrode, ejecting the old electrode remnant, and clamping the new electrode. This significantly reduces non-welding auxiliary time and is particularly suitable for scenarios involving all-position welding of equal-length welds in pipelines that require frequent electrode replacement, effectively improving overall work efficiency.

[0014] 2. In traditional welding vehicles powered by new energy sources, welding workers must handle the hot electrode residue and potentially scalding jaws with their bare hands or while wearing heavy gloves during electrode replacement, posing a risk of burns and making the process inconvenient. This invention completely avoids direct contact between the welder and high-temperature components. All replacement actions are completed internally by a mechanical mechanism, fundamentally eliminating the risk of burns. Furthermore, it simplifies the complex replacement process into a single press / release operation, reducing operational complexity and labor intensity, improving ergonomics, and allowing welders to focus more on the welding process itself.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1

[0035] The left end of the feeder 6 is fixedly connected to a fixed frame 34. The inner sides of both sides of the fixed frame 34 are rotatably connected to a third rotating shaft 35. A rotating frame 37 is fixedly connected between the two third rotating shafts 35. Two guide rollers 38 are rotatably connected to the inner wall of the middle part of the rotating frame 37. Damping blocks are installed on the inner sides of both sides of the rotating frame 37. The surfaces of the two damping blocks are in contact with the outer sides of the two guide rollers 38 respectively. Before the welding core tail end of the welding rod 10 is clamped by the damping blocks, the welding rod 10 is prevented from falling between the two guide rollers 38 under the action of gravity.

[0036] The rotating frame 37 has drive boxes 39 fixedly connected to both outer sides. Each drive box 39 has a threaded rod 44 rotatably connected to it via bearings. Each threaded rod 44 has a push block 45 threadedly connected to its outer side. One end of each push block 45 extends to the middle of the rotating frame 37 and is fixedly connected to a clamping block 46. One side of one clamping block 46 is fixedly connected to a sub-cable, which is electrically connected to the main cable. The inner side of the fixed frame 34, located in the circumferential direction of the third rotating shaft 35, has an arc-shaped guide groove 40. One end of each threaded rod 44 extends into the arc-shaped guide groove 40 and is fixedly fitted with a second gear 50. The inner wall of the arc-shaped guide groove 40 is fixedly connected to an arc-shaped tooth segment 47 for driving the second gear 50 to rotate. The second gear 50 engages with the arc-shaped tooth segment 47 to drive the threaded rod 44 to rotate, thereby driving the push block 45 and clamping block 46 to move.

[0037] The top of the feeder 6 is fixedly connected to a top cover 8 by screws. Several first springs 11 are fixedly connected to the top of the inner cavity of the top cover 8. The bottom ends of the first springs 11 are fixedly connected to the top of the abutment plate 12 placed below the first springs 11. The outer periphery of the abutment plate 12 is in contact with the inner wall of the feeder 6. When replenishing welding rods 10, the top cover 8 is removed from the top of the feeder 6 by unscrewing the screws. The welding rods 10 are stacked and placed into the opening 9. Then the top cover 8 is placed back into the top of the feeder 6. The screws are then screwed back into the feeder 6 to fix the top cover 8. After the feeding is completed, the top column 27 moves to the initial position. At this time, the first springs 11 push the abutment plate 12 down, so that the abutment plate 12 pushes the stacked welding rods 10 to the bottom of the inner cavity of the feeder 6 to await feeding.

[0038] Two fixing blocks 13 are fixedly connected to the left end of the feeder 6. A first rotating shaft 14 is rotatably connected between the two fixing blocks 13 via a bearing. A baffle 16 is fixedly connected to the outside of the first rotating shaft 14. A first torsion spring 15 is installed inside one of the fixing blocks 13. One end of the first torsion spring 15 is fixedly connected to the inner wall of the fixing block 13, and the other end of the first torsion spring 15 is fixedly connected to the outside of one end of the first rotating shaft 14 that extends into the inside of the fixing block 13. After the top column 27 finishes feeding, the left end of the top column 27 moves into the feeder 6. At this time, the elastic potential energy of the tightened first torsion spring 15 drives the first rotating shaft 14 to drive the baffle 16 to reset and rotate, so that one end of the baffle 16 is inserted into the through-hole 9, preventing the welding rod 10 in the inner cavity of the feeder 6 from falling out of the through-hole 9 under the action of gravity.

[0039] Two mounting blocks 48 are fixedly connected to the rear surface of the grip 5. A pressure handle 19 is rotatably connected between the two mounting blocks 48 via a hinge shaft. A second torsion spring 41 is installed inside the upper mounting block 48. One end of the second torsion spring 41 is fixedly connected to the inner wall of the mounting block 48, and the other end of the second torsion spring 41 is fixedly connected to the outside of the hinge shaft extending into the mounting block 48. A piston cylinder 7 is embedded in the top of the grip 5. A piston block 21 is slidably connected inside the piston cylinder 7. A push post 17 is fixedly connected to one end of the piston block 21. One end of the push post 17 extends to the outside of the piston cylinder 7. A second return spring 18 is sleeved on the outside of the push post 17. One end of the second return spring 18 is fixedly connected to the surface of the piston cylinder 7, and the other end of the second return spring 18 is fixedly connected to one end of a collar fixed to the outside of the push post 17. The end of the push post 17 near the pressure handle 19 is set as an arc end face, which allows the pressure handle 19 to push the push post 17 to move.

[0040] The bottom of the lower cavity inner wall of the drive chamber 25 is rotatably connected to a second rotating shaft 30. A bottom groove 26 is formed at the bottom of the top column 27, with the right end of the groove 26 extending to the outside of the right end of the top column 27. The top end of the second rotating shaft 30 is inserted into the bottom groove 26 and a first gear 29 is fixedly fitted thereon. A rack 28 is fixedly connected to the inner wall of the bottom groove 26, driving the first gear 29 to rotate. A transmission box 36 is fixedly connected to one side of the handle 5, with one end of the transmission box 36 extending to the rear of the fixed frame 34. One end of a third rotating shaft 35 extends to the transmission... A worm gear 43 is fixedly fitted inside the housing 36. A worm 42 is rotatably connected to the left side of the worm gear 43 inside the transmission housing 36, and the worm 42 is connected to the worm gear 43. A first sprocket 31 is rotatably connected inside the transmission housing 36. A second sprocket 33 connected by a chain drive is fixedly fitted on the outer side of the first sprocket 31 and the outer side of the smooth rod of the worm 42. The second rotating shaft 30 and the outer side of the rotating column 32 are both fixedly fitted with the first sprocket 31 connected by a chain drive. The first gear 29 can be driven to rotate by the rack 28 located at the right rear of the bottom groove 26.

[0041] The piston cylinder 7 is fixedly connected to a pipe 20 at one end. A drive groove 22 is provided inside the handle 5 and in front of the bottom groove 26. A third support spring 23 is fixedly connected to one side of the inner cavity of the drive groove 22. One end of the top column 27 extends into the drive groove 22. One end of the third support spring 23 is fixedly connected to one end of the top column 27. A liquid bladder 24 is fixedly connected to the right end of the inner cavity of the drive groove 22. One end of the pipe 20 extends into the liquid bladder 24. The top column 27 is driven to extend or retract by the expansion and contraction of the liquid bladder 24 and the cooperation of the third support spring 23.

[0042] Example 2

[0043] Please see Figure 16 This invention provides a technical solution: an electronic control system for a new energy welding engineering vehicle, comprising: a walking system, a welding system, a vehicle-mounted crane superstructure system, an auxiliary drive system, a power battery system, a VCU control system, and a cooling system. The walking system adopts a hydraulic full-power variable and servo control system. The power requirement is calculated based on the maximum flow rate, pressure, and working efficiency of the hydraulic pump. After safety monitoring by the PDU cabinet, the walking motor is controlled by a five-in-one controller.

[0044] The power required by the welding machine in the welding system is led out through the PDU cabinet inverter. The working hydraulic system on the truck crane 3 is connected to the main pump motor, and the motor controller adopts a five-in-one controller.

[0045] The auxiliary drive system mainly consists of a DC-DC converter, air conditioner, water cooling system, air compressor, grinding wheel, water pump, and various lighting equipment. The grinding wheel and various lighting equipment are powered by AC 380V (or 220V) from the PDU distribution box.

[0046] The vehicle uses a DC-DC converter with a 3.0kW power supply, and a 5.5kW power supply to meet the power needs of the air conditioning and 5.5kW electric heater.

[0047] The all-in-one controller includes a main pump motor controller, a 13KW DCAC controller for the air compressor, a 5.5KW DCAC controller for the water pump, and a DC / DC converter.

[0048] The welding engineering vehicle has several working modes, including self-propelled, equipped with welding equipment, power generation, and lifting. It is mainly used to meet the needs of manual arc welding, semi-automatic welding, and fully automatic welding of various long-distance oil and gas pipelines.

[0049] The welding vehicle does not weld while moving, and does not move while welding. The on-board crane 3 is generally used to adjust the position of the windproof canopy. During welding, manual welding, semi-automatic welding, and fully automatic welding equipment can be accessed from the storage power supply box 2 and connected to the welding power supply on the electric drive chassis 1 to initiate arc welding.

[0050] When welding manually, take out the manual welding equipment, then connect one pole of the arc welding host 4 to the handle 5 through a cable, connect the arc welding host 4 to the welding power supply on the electric drive chassis 1 through a cable, connect the ground wire clamp to the other pole of the arc welding host 4, and firmly clamp the ground wire clamp onto the pipe.

[0051] During the welding process, the user holds the handle 5 and uses the welding rod 10 held at the front end to initiate arc welding at the connection of the two pipes.

[0052] When it is necessary to replace the welding rod 10, pick up the welding rod 10 from the pipe, and then press the pressure handle 19 with your hand. This will cause one end of the pressure handle 19 to rotate towards the handle 5, and the surface of the pressure handle 19 will push the arc end face of the push column 17 to move. At this time, the pressure handle 19 will drive the hinge shaft to rotate, which will tighten the second torsion spring 41. This will cause the push column 17 to push the piston block 21 to input the hydraulic oil inside the piston cylinder 7 into the pipeline 20. The hydraulic oil will then enter the liquid bladder 24 through the pipeline 20, causing the liquid bladder 24 to expand and overcome the supporting force of the third support spring 23 on the top column 27. This will push the left end of the top column 27 through the port 9 behind the feeder 6 into the feeder 6. At this time, the left end of the top column 27 will push a welding rod 10 below the inner cavity of the feeder 6 through a port 9 on the left end of the feeder 6 and move it to the outside of the left end of the feeder 6.

[0053] During the process of pushing the welding rod 10 into the through-hole 9 through the left end of the top post 27, the top post 27 drives the rack 28 to move to the left, causing the rack 28 to drive the first gear 29 to rotate. The first gear 29 drives a first sprocket 31 to rotate through the second rotating shaft 30. This first sprocket 31 drives another first sprocket 31 to rotate through a chain belt. This first sprocket 31 drives the rotating column 32 to rotate. This first sprocket 31 drives the rotating column 32 to rotate. This rotating column 32 drives a second sprocket 33 to rotate. This second sprocket 33 drives another second sprocket 33 to rotate through a chain belt. This second sprocket 33 drives the worm gear 42 to rotate. This worm gear 42 drives the worm wheel 43 and a third... Rotating shaft 35 rotates, causing the third rotating shaft 35 to drive the rotating frame 37 to rotate from an inclined state to a horizontal state. At this time, the rotating frame 37 drives another third rotating shaft 35 to rotate together. During the rotation of the rotating frame 37 to a horizontal state, the rotating frame 37 drives the drive box 39 and the second gear 50 to move in a circle. The second gear 50 moves along the inner side of the arc-shaped tooth segment 47 inside the arc-shaped guide groove 40, so that the tooth groove on the arc-shaped tooth segment 47 engages with the outer teeth of the second gear 50. The second gear 50 drives the threaded rod 44 to rotate, so that the threaded rod 44 drives the push block 45 and the clamping block 46 to move into the drive box 39, releasing the limiting and fixing state of the remaining welding core tail of the used welding rod 10.

[0054] Then the welding rod 10 continues to move, causing one end of the welding rod 10 to push the baffle 16 to rotate, causing the baffle 16 to drive the first rotating shaft 14 to rotate, causing the first rotating shaft 14 to drive the first torsion spring 15 to tighten, thereby causing one end of the welding rod 10 to move out of the inside of the feeder 6 through the through port 9, so that one end of the welding rod 10 passes between the two guide rollers 38. At this time, the welding rod 10 pushes out the remaining part of the previous used welding rod 10 from the left front of the two guide rollers 38. At this time, the tail end of the welding core of the welding rod 10 is located between the two clamping blocks 46, and the left end of the top column 27 is located in the left front of the feeder 6.

[0055] Then, the pressure handle 19 is released. At this time, the tightened second torsion spring 41 releases its elastic potential energy to drive the hinge shaft to rotate back to its original position. This causes the hinge shaft to drive the pressure handle 19 to rotate back to its original position. At this time, the second return spring 18 pushes the collar and push column 17 to move back to their original positions. This causes the push column 17 to drive the piston block 21 to move towards the pressure handle 19. At this time, a suction force is generated inside the piston cylinder 7, which causes the hydraulic oil inside the liquid bladder 24 to be drawn into the piston cylinder 7 through the pipe 20. At this time, the liquid bladder 24 gradually contracts, causing the third support spring 23 to push the top column 27 to move to the right end. This causes the top column 27 to gradually move into the drive chamber 25. At this time, the movement of the top column 27 brings... The moving rack 28 moves to the right of the first gear 29, causing the rack 28 to drive the first gear 29 to reset and rotate. This causes the first gear 29 to drive a first sprocket 31 to reset and rotate via the second rotating shaft 30. This first sprocket 31 then drives another first sprocket 31 to reset and rotate via a chain belt. This first sprocket 31 drives the rotating column 32 to reset and rotate. This rotating column 32 then drives a second sprocket 33 to reset and rotate. This second sprocket 33 then drives another second sprocket 33 to reset and rotate via a chain belt. The worm gear 42 rotates to its reset position, causing the worm wheel 43 and a third rotating shaft 35 to rotate to their reset positions. This causes the third rotating shaft 35 to rotate the rotating frame 37 from a horizontal to an inclined position. Simultaneously, the rotating frame 37 rotates the other third rotating shaft 35. During this inclined rotation, the rotating frame 37 causes the drive box 39 and the second gear 50 to move in a circular motion. This causes the second gear 50 to move along the inner side of the arc-shaped tooth segment 47 within the arc-shaped guide groove 40, allowing the tooth grooves on the arc-shaped tooth segment 47 to engage with the outer teeth of the second gear 50, thus driving the second gear... Wheel 50 drives threaded rod 44 to rotate, causing threaded rod 44 to drive push block 45 and clamping block 46 to move inward toward rotating frame 37, limiting and fixing the tail end of welding core of welding rod 10. At this time, the two clamping blocks 46 apply current to the welding core of welding rod 10 through sub-cable and main cable. Ground clamp is clamped on clean workpiece, and a circuit is formed between welding rod 10 and ground clamp. After welding rod 10 contacts the pipe, it is lifted instantly, generating an electric arc of up to several thousand degrees. The electric arc melts the metal core of welding rod 10 and the part of pipe to be welded at the same time, forming a molten pool. After the coating of welding rod 10 melts, it generates gas and slag, protecting the molten pool from air pollution.

[0056] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of shaft-shaped parts are connected by bearings, the connection position of valve components is provided with anti-leakage rubber strips, the outside of threaded rods or lead rods is provided with dust covers, and the equipment can be driven by either built-in batteries or external power supply.
