Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, and specifically relates to an automatic welding equipment for cable trays. Background Technology

[0002] Cable trays are support and protection devices used for laying power, control, and communication cables. They can organize the route of the line, support the weight of the cable, reduce external damage and electromagnetic interference, and have good heat dissipation performance. They facilitate the installation, maintenance and expansion of the line, and can improve the safety and standardization of wiring. They are widely used in construction, power, chemical and other engineering fields.

[0003] Cable trays come in various configurations, among which ladder-type cable trays are widely used due to their simple structure, light weight, and good heat dissipation. Ladder-type cable trays are welded together from two side plates and multiple crossbars, making welding one of the most crucial steps in their production process. The welding process requires a large number of crossbars and frequent feeding. Traditional production methods often rely on manual placement, resulting in low efficiency. While using robotic arms for feeding is costly, an automated cable tray welding machine capable of automatically feeding the crossbars is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic welding equipment for cable trays. In the present invention, the driving mechanism can drive the material conveying mechanism to periodically and intermittently transport the cable trays to be welded through the transmission mechanism, so that the crossbars can be placed at equal intervals in the cable trays to be welded. Then the welding mechanism welds the crossbars one by one onto the cable trays to be welded, thereby completing the welding of the cable trays. The whole process does not require manual placement of the crossbars, effectively improving production efficiency.

[0005] The technical solution adopted to solve the above technical problems is: an automatic cable tray welding equipment, including a feeding mechanism, a driving mechanism and a storage mechanism. The feeding mechanism is fixedly installed on the ground and can transport the cable tray to be welded. The storage mechanism is fixedly installed above the feeding mechanism and the driving mechanism is installed above the storage mechanism. The storage mechanism stores multiple crossbars and the driving mechanism can send the crossbars in the storage mechanism into the cable tray to be welded.

[0006] A welding mechanism is provided on the front side of the material storage mechanism, which can weld the crossbar to the cable tray to be welded.

[0007] The material conveying mechanism consists of two sets, which are symmetrically fixed on the ground. A transmission mechanism is provided on the side of the material conveying mechanism, and the driving mechanism can drive the material conveying mechanism to periodically and intermittently convey the cable tray to be welded through the transmission mechanism.

[0008] With the above technical solution, during operation, the cable tray to be welded is conveyed forward by the material conveying mechanism, and the drive mechanism presses the crossbars in the storage mechanism into the cable tray to be welded. At the same time, the drive mechanism can also drive the material conveying mechanism to periodically and intermittently convey the cable tray to be welded through the transmission mechanism, so that the crossbars can be placed at equal intervals in the cable tray to be welded. Then, the welding mechanism welds the crossbars onto the cable tray one by one, thereby completing the welding of the cable tray. The whole process does not require manual placement of crossbars, which effectively improves production efficiency, significantly reduces labor costs and operational errors, and the equipment operates stably with low cost, effectively reducing the enterprise's production costs.

[0009] Furthermore, the driving mechanism includes a driving plate, a hydraulic lifting rod, and a driving frame. The driving frame is fixedly mounted above the material storage mechanism, the hydraulic lifting rod is fixedly connected to the driving frame, and the top of the driving plate is fixedly connected to the bottom of the hydraulic lifting rod.

[0010] With the above technical solution, since the drive frame is fixedly set above the storage mechanism, the hydraulic lifting rod is fixedly connected to the drive frame, and the top of the drive plate is fixedly connected to the bottom of the hydraulic lifting rod, the hydraulic lifting rod can drive the drive plate to rise and fall vertically.

[0011] Furthermore, a pressure block is fixedly connected to the bottom of the drive plate, a pressure strip is fixedly connected to the front side of the drive plate, a pressure plate is fixedly connected to the front side of the drive plate, a drive inclined block is fixedly connected to the bottom of the drive plate, the drive inclined block is located behind the pressure block, and drive racks are symmetrically fixedly connected to both sides of the drive plate.

[0012] With the above technical solution, a pressure block is fixedly connected to the bottom of the drive plate, a pressure strip is fixedly connected to the front side of the drive plate, a pressure plate is fixedly connected to the front side of the drive plate, a drive inclined block is fixedly connected to the bottom of the drive plate, the drive inclined block is located behind the pressure block, and drive racks are symmetrically fixedly connected to both sides of the drive plate, so that the drive plate can drive the pressure block, drive inclined block, drive rack, pressure strip and pressure plate to move up and down synchronously and vertically.

[0013] Furthermore, the material storage mechanism includes a material storage frame, a pusher plate, and a limiting frame. The material storage frame is fixedly installed above the material conveying mechanism, the pusher plate is slidably connected to the bottom of the material storage frame, and the limiting frame is fixedly connected to the front side of the material storage frame. The material storage frame stores multiple horizontal bars.

[0014] With the above technical solution, since the storage frame is fixedly set above the conveying mechanism, the pusher plate is slidably connected to the bottom of the storage frame, and the limiting frame is fixedly connected to the front side of the storage frame, and multiple horizontal bars are stored in the storage frame, the pusher plate can push the horizontal bars in the storage frame into the limiting frame.

[0015] Furthermore, the pusher plate passes through the storage frame, a driven inclined block is fixedly connected to the rear side of the pusher plate, and first return springs are symmetrically fixedly connected to both sides of the pusher plate. The other end of the first return spring is fixedly connected to the rear side of the storage frame. The pressing block can pass through the limiting frame from above, and the inclined surface of the driving inclined block and the inclined surface of the driven inclined block can fit together.

[0016] Through the above technical solution, since the pusher plate penetrates through the storage frame, a driven inclined block is fixedly connected to the rear side of the pusher plate, and first return springs are symmetrically fixedly connected to both sides of the pusher plate, with the other end of the first return springs fixedly connected to the rear side of the storage frame, the pressure block can penetrate through the limiting frame from above. The inclined surface of the driving inclined block and the inclined surface of the driven inclined block can fit together, so that when the driving inclined block descends with the driving plate, the driving inclined block can squeeze the driven inclined block, thereby causing the driven inclined block to drive the pusher plate to slide forward. The forward sliding of the pusher plate can push the bottommost horizontal bar in the storage frame towards the limiting frame, while the pressure block... The material block also descends with the drive plate. The pressure block can press the crossbar pushed into the limiting frame down onto the bridge to be welded. After the drive plate rises, the pressure block rises accordingly, freeing up the space in the limiting frame. At this time, the drive inclined block also rises. The rise of the drive inclined block makes the driven inclined block no longer squeezed. At this time, the first reset spring drives the push plate to slide backward. The push plate exits the storage frame. The remaining crossbar in the storage frame descends with gravity. The push plate and the pressure block are both reset. By repeating the above steps, the continuous automatic feeding of the crossbar can be achieved, providing stable material support for the welding process.

[0017] Furthermore, the material conveying mechanism includes a material conveying bracket, driven rollers, and a conveyor belt. The material conveying bracket is fixedly installed on the ground. There are two sets of driven rollers, which are symmetrically rotatably connected to the material conveying bracket. The conveyor belt is sleeved on the driven rollers. The inner side of the conveyor belt is provided with toothed grooves. The driven rollers are provided with teeth that mesh with the toothed grooves. A clamping assembly and a pressing assembly are fixedly installed on the material conveying bracket. The clamping assembly is located on the front side of the material conveying bracket, and the pressing assembly is located on the rear side of the material conveying bracket. The clamping assembly includes a clamping frame and guide wheels. The pressing assembly includes a pressing frame and guide wheels. The guide wheels on the clamping assembly are two sets that are horizontally symmetrically rotatably connected to the clamping frame, and the guide wheels on the pressing assembly are two sets that are vertically symmetrically rotatably connected to the pressing frame.

[0018] Through the above technical solution, since there are two sets of driven rollers, which are symmetrically rotatably connected to the conveying support, the conveyor belt is sleeved on the driven rollers, and the inner side of the conveyor belt is provided with toothed grooves. The driven rollers are provided with teeth that mesh with the toothed grooves. The conveying support is fixedly equipped with a clamping assembly and a pressing assembly. The clamping assembly is located on the front side of the conveying support, and the pressing assembly is located on the rear side of the conveying support. The clamping assembly includes a clamping frame and guide wheels, and the pressing assembly includes a pressing frame and guide wheels. The guide wheels on the clamping assembly are two sets that are horizontally symmetrically rotatably connected to the clamping frame. On the material rack, the guide wheels on the pressing assembly are two sets of vertically symmetrically connected to the pressing frame, so that the conveyor belt is supported by the driven rollers. The conveyor belt can stably transport the bridge frame to be welded. The guide wheels on the clamping assembly and the pressing assembly are symmetrically arranged on the inner and outer sides of the bridge frame to be welded. The clamping assembly limits the bridge frame to be welded in the horizontal direction, and the pressing assembly limits the bridge frame to be welded in the vertical direction, so that the bridge frame to be welded is stably placed on the conveyor belt, thereby ensuring that it does not deviate or shake during the conveying process, and ensuring the welding positioning accuracy and process stability.

[0019] Furthermore, the transmission mechanism includes a drive roller, a transmission ring, and a movable tooth. The drive roller is rotatably connected to the material conveying bracket, the transmission ring is rotatably connected to the material conveying bracket, and the movable tooth is rotatably connected to the drive roller shaft. The drive roller is provided with teeth that mesh with the tooth grooves on the conveyor belt. The drive roller shaft is provided with a limiting arc groove, and the movable tooth rotates in a restricted manner on the drive roller shaft.

[0020] With the above technical solution, since the drive roller is rotatably connected to the material conveying bracket, the transmission ring is rotatably connected to the material conveying bracket, the movable tooth is rotatably connected to the drive roller shaft, the drive roller is provided with teeth, the teeth on the drive roller mesh with the tooth grooves on the conveyor belt, the drive roller shaft is provided with a limiting arc groove, and the movable tooth rotates restricted on the drive roller shaft, so that the rotation of the drive roller can drive the conveyor belt to move, thereby conveying the bridge frame to be welded.

[0021] Furthermore, a helical gear ring is provided on the inner side of the transmission ring, and a driven gear ring is provided on the outer side of the transmission ring. The movable tooth meshes with the helical gear ring in one direction, and the driven gear ring can mesh with the drive rack.

[0022] With the above technical solution, since a helical gear ring is provided on the inner side of the transmission ring and a driven gear ring is provided on the outer side of the transmission ring, the movable teeth mesh with the helical gear ring in one direction, and the driven gear ring can mesh with the drive rack. When the drive rack descends with the drive plate, the drive rack drives the driven gear ring to reverse, the driven gear ring reverses, drives the transmission ring to reverse, and the transmission ring reverses, drives the helical gear ring to reverse. At this time, the movable teeth do not mesh with the helical gear ring, and the drive roller does not rotate.

[0023] When the drive rack rises with the drive plate, the drive rack drives the driven gear ring to rotate forward. The forward rotation of the driven gear ring drives the transmission ring to rotate forward. The forward rotation of the transmission ring drives the helical gear ring to rotate in reverse. At this time, the movable tooth meshes with the helical gear ring, realizing the forward rotation of the drive roller. The forward rotation of the drive roller drives the conveyor belt to transport the bridge frame to be welded forward.

[0024] Furthermore, the welding mechanism includes a welding bracket, a welding torch, and a connecting beam. The welding bracket is fixedly installed on the ground. There are two sets of welding torches, which are slidably connected vertically to the welding bracket. The connecting beam fixes the two sets of welding torches together. A guide rod is fixedly connected to the top of the welding torch. The guide rod passes through the welding bracket and is slidably connected to the welding bracket. Two second return springs are symmetrically fixedly connected to the top of the welding bracket. The second return springs are sleeved on the guide rods, and the bottom of the second return springs is fixedly connected to the top of the welding torch.

[0025] With the above technical solution, since there are two sets of welding torches, the welding torches are vertically and slidably connected to the welding bracket. The connecting beam fixes the two sets of welding torches together. A guide rod is fixedly connected to the top of the welding torch, and the guide rod passes through the welding bracket. The guide rod is slidably connected to the welding bracket. Two second return springs are symmetrically fixedly connected to the top of the welding bracket. The second return springs are sleeved on the guide rods, and the bottom of the second return springs is fixedly connected to the top of the welding torch. This allows the two sets of welding torches to weld on both sides of the crossbar simultaneously, improving welding efficiency while ensuring the welding accuracy of the crossbar. The welding torches can slide vertically on the welding bracket, ensuring that the crossbar on the bridge to be welded will not collide with the welding torch during the conveying process, thus ensuring the safe operation of the equipment.

[0026] Furthermore, the pressure strip can contact the top of the connecting crossbeam, and the pressure plate can contact the top of the crossbar to be welded.

[0027] With the above technical solution, since the pressure strip can contact the top of the connecting crossbeam and the pressure plate can contact the top of the crossbar to be welded, when the drive plate descends, the pressure strip and the pressure plate descend accordingly. The descent of the pressure strip can drive the connecting crossbeam to descend, so that the welding gun can weld the crossbar that reaches below the welding bracket. The pressure plate can press down the crossbar that reaches below the welding bracket, thereby ensuring that the crossbar is stable in position during the welding process. The gun head on the welding gun can move, thereby completing the welding of the crossbar to the cable tray to be welded.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) When the drive plate descends in this invention, the conveyor belt stops running, the pusher plate pushes the crossbar in the storage box to the limit box, and the pressure block presses the crossbar pushed into the limit box onto the bridge frame to be welded. When the drive plate rises, the pusher plate and the pressure block are reset. The drive rack drives the conveyor belt through the transmission mechanism to transport the bridge frame to be welded forward a distance, so that the crossbars are placed at equal intervals on the bridge frame to be welded, thereby completing the continuous automatic feeding of the crossbars. The whole process does not require manual placement of the crossbars, which effectively improves production efficiency, significantly reduces labor costs and operating errors, and the equipment runs stably with low cost, effectively reducing the production cost of enterprises.

[0030] (2) In this invention, welding can be performed when the drive plate is lowered and the conveyor belt is paused. At this time, the drive plate is lowered, and the pressure bar and pressure plate are lowered accordingly. The lowering of the pressure bar can drive the connecting beam to be lowered, thereby lowering the welding gun so that the welding gun can weld the crossbar that reaches the bottom of the welding bracket. The pressure plate can press down the crossbar that needs to be welded that reaches the bottom of the welding bracket, thereby ensuring that the crossbar is stable in position during the welding process. The reciprocating lifting and lowering of the drive plate on the drive mechanism can coordinate and synchronize the automatic placement of the crossbar, the conveying of the bridge to be welded and the welding process, effectively improving production efficiency.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] like Figure 1 - Figure 7As shown, an automatic cable tray welding device includes a feeding mechanism 1, a driving mechanism 2, and a storage mechanism 3. The feeding mechanism 1 is fixedly installed on the ground and can transport the cable tray 6 to be welded. The storage mechanism 3 is fixedly installed above the feeding mechanism 1. The driving mechanism 2 is installed above the storage mechanism 3. The storage mechanism 3 stores a plurality of crossbars 61. The driving mechanism 2 can send the crossbars 61 in the storage mechanism 3 onto the cable tray 6 to be welded.

[0048] A welding mechanism 5 is provided on the front side of the material storage mechanism 3. The welding mechanism 5 can weld the crossbar 61 to the cable tray 6 to be welded.

[0049] The material conveying mechanism 1 consists of two sets, which are symmetrically fixed on the ground. The side of the material conveying mechanism 1 is equipped with a transmission mechanism 4. The drive mechanism 2 can drive the material conveying mechanism 1 to periodically and intermittently convey the cable tray 6 to be welded through the transmission mechanism 4.

[0050] In this embodiment, during operation, the cable tray 6 to be welded is conveyed forward by the material conveying mechanism 1, and the driving mechanism 2 presses the crossbars 61 in the storage mechanism 3 into the cable tray 6 to be welded. At the same time, the driving mechanism 2 can also drive the material conveying mechanism 1 to periodically and intermittently convey the cable tray 6 to be welded through the transmission mechanism 4, so that the crossbars 61 can be placed equidistantly in the cable tray 6 to be welded. Then, the welding mechanism 5 welds the crossbars 61 one by one onto the cable tray 6 to be welded, thereby completing the welding of the cable tray. The entire process does not require manual placement of the crossbars 61, which effectively improves production efficiency, significantly reduces labor costs and operational errors, and the equipment operates stably with low cost, effectively reducing the enterprise's production costs.

[0051] like Figure 2 - Figure 3 As shown, the drive mechanism 2 includes a drive plate 21, a hydraulic lifting rod 22 and a drive frame 23. The drive frame 23 is fixedly installed above the storage mechanism 3, the hydraulic lifting rod 22 is fixedly connected to the drive frame 23, and the top of the drive plate 21 is fixedly connected to the bottom of the hydraulic lifting rod 22.

[0052] A pressure block 211 is fixedly connected to the bottom of the drive plate 21, a pressure strip 214 is fixedly connected to the front side of the drive plate 21, a pressure plate 215 is fixedly connected to the front side of the drive plate 21, a drive inclined block 212 is fixedly connected to the bottom of the drive plate 21, the drive inclined block 212 is located behind the pressure block 211, and drive racks 213 are symmetrically fixedly connected to both sides of the drive plate 21.

[0053] In this embodiment, the hydraulic lifting rod 22 can drive the drive plate 21 to rise and fall vertically, and the drive plate 21 can drive the pressing block 211, the drive inclined block 212, the drive rack 213, the pressing strip 214 and the pressing plate 215 to rise and fall vertically synchronously.

[0054] like Figure 1 - Figure 6As shown, the material storage mechanism 3 includes a material storage frame 31, a pusher plate 32 and a limiting frame 33. The material storage frame 31 is fixedly installed above the material conveying mechanism 1. The pusher plate 32 is slidably connected to the bottom of the material storage frame 31. The limiting frame 33 is fixedly connected to the front side of the material storage frame 31. Multiple crossbars 61 are stored in the material storage frame 31.

[0055] The pusher plate 32 passes through the storage frame 31. A driven inclined block 321 is fixedly connected to the rear side of the pusher plate 32. A first reset spring 311 is symmetrically fixedly connected to both sides of the pusher plate 32. The other end of the first reset spring 311 is fixedly connected to the rear side of the storage frame 31. The pressing block 211 can pass through the limiting frame 33 from above. The inclined surface of the driving inclined block 212 can fit with the inclined surface of the driven inclined block 321.

[0056] In this embodiment, when the driving inclined block 212 descends with the driving plate 21, it can press the driven inclined block 321, thereby causing the driven inclined block 321 to drive the pusher plate 32 to slide forward. The forward sliding of the pusher plate 32 can push the lowest layer of the horizontal bar 61 in the storage frame 31 towards the limiting frame 33. The pressing block 211 also descends with the driving plate 21, and the pressing block 211 can press the horizontal bar 61 pushed into the limiting frame 33 onto the bridge frame 6 to be welded. After the driving plate 21 rises, the pressing block 211... As it rises, it frees up the space inside the limiting frame 33. At this time, the driving inclined block 212 also rises. The rise of the driving inclined block 212 makes the driven inclined block 321 no longer squeezed. At this time, the first reset spring 311 drives the pusher plate 32 to slide backward. The pusher plate 32 exits the storage frame 31. The remaining crossbar 61 in the storage frame 31 falls with gravity. The pusher plate 32 and the pressing block 211 are both reset. By repeating the above steps, the crossbar 61 can be continuously and automatically fed, providing stable material support for the welding process.

[0057] like Figure 1 - Figure 10 As shown, the material conveying mechanism 1 includes a material conveying support 11, a driven roller 12, and a conveyor belt 13. The material conveying support 11 is fixedly installed on the ground. There are two sets of driven rollers 12, which are symmetrically rotatably connected to the material conveying support 11. The conveyor belt 13 is sleeved on the driven roller 12. The inner side of the conveyor belt 13 is provided with tooth grooves. The driven roller 12 is provided with teeth that mesh with the tooth grooves. The material conveying support 11 is fixedly installed with a clamping assembly 14 and a pressing assembly 15. The clamping assembly 14 is located on the front side of the material conveying support 11, and the pressing assembly 15 is located on the rear side of the material conveying support 11. The clamping assembly 14 includes a clamping frame 141 and guide wheels. The pressing assembly 15 includes a pressing frame 151 and guide wheels. The guide wheels on the clamping assembly 14 are two sets that are horizontally symmetrically rotatably connected to the clamping frame 141. The guide wheels on the pressing assembly 15 are two sets that are vertically symmetrically rotatably connected to the pressing frame 151.

[0058] The transmission mechanism 4 includes a drive roller 41, a transmission ring 42, and a movable tooth 43. The drive roller 41 is rotatably connected to the material conveying bracket 11, the transmission ring 42 is rotatably connected to the material conveying bracket 11, and the movable tooth 43 is rotatably connected to the drive roller 41 shaft. The drive roller 41 is provided with teeth, which mesh with the tooth grooves on the conveyor belt 13. The drive roller 41 shaft is provided with a limiting arc groove 411, and the movable tooth 43 rotates in a restricted manner on the drive roller 41 shaft.

[0059] A helical gear ring 421 is provided on the inner side of the transmission ring 42, and a driven gear ring 422 is provided on the outer side of the transmission ring 42. The movable tooth 43 meshes with the helical gear ring 421 in one direction, and the driven gear ring 422 can mesh with the drive rack 213.

[0060] In this embodiment, the conveyor belt 13 is supported by the driven roller 12. The conveyor belt 13 can stably transport the bridge frame 6 to be welded. The guide wheels on the clamping assembly 14 and the pressing assembly 15 are symmetrically arranged on the inner and outer sides of the bridge frame 6 to be welded. The clamping assembly 14 limits the bridge frame 6 to be welded in the horizontal direction, and the pressing assembly 15 limits the bridge frame 6 to be welded in the vertical direction, so that the bridge frame 6 to be welded is stably placed on the conveyor belt 13, thereby ensuring that it does not deviate or shake during the conveying process, and ensuring the welding positioning accuracy and process stability.

[0061] When the drive rack 213 rises with the drive plate 21, the drive rack 213 drives the driven gear ring 422 to rotate forward. The forward rotation of the driven gear ring 422 drives the transmission ring 42 to rotate forward. The forward rotation of the transmission ring 42 drives the helical gear ring 421 to rotate in reverse. At this time, the movable tooth 43 meshes with the helical gear ring 421, realizing the forward rotation of the drive roller 41. The forward rotation of the drive roller 41 drives the conveyor belt 13 to transport the bridge frame 6 to be welded forward.

[0062] When the drive rack 213 descends with the drive plate 21, the drive rack 213 drives the driven gear ring 422 to reverse, the driven gear ring 422 reverses, drives the transmission ring 42 to reverse, and the transmission ring 42 reverses, drives the helical gear ring 421 to reverse. At this time, the movable tooth 43 does not mesh with the helical gear ring 421, the drive roller 41 does not rotate, the drive roller 41 remains stationary, and the conveyor belt 13 stops running, which facilitates the execution of the welding process.

[0063] like Figure 11 - Figure 14As shown, the welding mechanism 5 includes a welding bracket 51, a welding torch 52, and a connecting beam 53. The welding bracket 51 is fixedly installed on the ground. There are two sets of welding torches 52, which are vertically and slidably connected to the welding bracket 51. The connecting beam 53 fixes the two sets of welding torches 52 together. A guide rod 521 is fixedly connected to the top of the welding torch 52. The guide rod 521 passes through the welding bracket 51 and is slidably connected to the welding bracket 51. Two second return springs 54 are symmetrically fixedly connected to the top of the welding bracket 51. The second return springs 54 are sleeved on the guide rods 521, and the bottom of the second return springs 54 is fixedly connected to the top of the welding torch 52.

[0064] The pressure strip 214 can contact the top of the connecting beam 53, and the pressure plate 215 can contact the top of the crossbar 61 that needs to be welded.

[0065] In this embodiment, the two sets of welding torches 52 can weld on both sides of the crossbar 61 simultaneously, improving welding efficiency while ensuring the welding accuracy of the crossbar 61.

[0066] During the conveying process of the cable tray 6 to be welded, the welding torch 52 is in a high position, which ensures that the crossbar 61 on the cable tray 6 to be welded will not collide with the welding torch 52 during the conveying process, thus ensuring the safe operation of the equipment.

[0067] When welding is required, the drive plate 21 descends, and the pressure bar 214 and pressure plate 215 descend accordingly. The descent of the pressure bar 214 can drive the connecting beam 53 to descend, thereby causing the welding torch 52 to descend, so that the welding torch 52 can weld the crossbar 61 that has reached below the welding bracket 51. The pressure plate 215 can press down the crossbar 61 that needs to be welded that has reached below the welding bracket 51, thereby ensuring that the crossbar 61 is stable in position during the welding process.

[0068] Working principle:

[0069] During operation, the material storage mechanism 3 stores multiple crossbars 61, the bridge frame 6 to be welded is placed on the material conveying mechanism 1, and then the drive mechanism 2 is started;

[0070] As the drive plate 21 descends, the drive rack 213 descends with it. The drive rack 213 drives the driven gear ring 422 to reverse, which in turn drives the transmission ring 42 to reverse, and the transmission ring 42 to reverse, which in turn drives the helical gear ring 421 to reverse. At this time, the movable tooth 43 does not mesh with the helical gear ring 421, the drive roller 41 does not rotate, the drive roller 41 remains stationary, and the conveyor belt 13 stops running.

[0071] When the drive inclined block 212 descends with the drive plate 21, the drive inclined block 212 can squeeze the driven inclined block 321, thereby causing the driven inclined block 321 to drive the push plate 32 to slide forward. The push plate 32 sliding forward can push the bottommost horizontal bar 61 in the storage frame 31 towards the limiting frame 33. The pressing block 211 also descends with the drive plate 21, and the pressing block 211 can press the horizontal bar 61 pushed into the limiting frame 33 down onto the cable tray 6 to be welded.

[0072] Then the drive plate 21 rises, and the pressing block 211 rises accordingly, freeing up the space inside the limit frame 33. At this time, the drive inclined block 212 also rises. The rise of the drive inclined block 212 makes the driven inclined block 321 no longer squeezed. At this time, the first reset spring 311 drives the push plate 32 to slide backward. The push plate 32 exits the storage frame 31, and the remaining crossbar 61 in the storage frame 31 falls with gravity. The push plate 32 and the pressing block 211 are both reset.

[0073] At the same time, the drive rack 213 rises with the drive plate 21, and the drive rack 213 drives the driven gear ring 422 to rotate forward. The driven gear ring 422 rotates forward, which drives the transmission ring 42 to rotate forward. The transmission ring 42 rotates forward, which drives the helical gear ring 421 to rotate in reverse. At this time, the movable tooth 43 meshes with the helical gear ring 421, realizing the forward rotation of the drive roller 41. The forward rotation of the drive roller 41 drives the conveyor belt 13 to transport the bridge frame 6 to be welded forward.

[0074] Repeating the above steps, when the drive plate 21 descends, the conveyor belt 13 stops running, the pusher plate 32 pushes the crossbar 61 in the storage box 31 toward the limit box 33, and the pressing block 211 presses the crossbar 61 pushed into the limit box 33 onto the bridge frame 6 to be welded. When the drive plate 21 rises, both the pusher plate 32 and the pressing block 211 are reset. The drive rack 213 drives the conveyor belt 13 through the transmission mechanism 4 to transport the bridge frame 6 to be welded forward a certain distance, so that the crossbars 61 are placed at equal intervals on the bridge frame 6 to be welded, thereby completing the continuous automatic feeding of the crossbars 61. The whole process does not require manual placement of the crossbars 61, effectively improving production efficiency.

[0075] As the cable tray 6 to be welded is conveyed forward, the crossbar 61 to be welded on the cable tray 6 moves to below the welding mechanism 5. Welding can be performed when the drive plate 21 descends and the conveyor belt 13 stops running. At this time, the drive plate 21 descends, and the pressure bar 214 and pressure plate 215 descend accordingly. The descent of the pressure bar 214 can drive the connecting beam 53 to descend, thereby causing the welding gun 52 to descend, so that the welding gun 52 can weld the crossbar 61 that has reached below the welding bracket 51. The pressure plate 215 can press down the crossbar 61 that needs to be welded that has reached below the welding bracket 51, thereby ensuring that the crossbar 61 is stable in position during the welding process.

[0076] After welding is completed, the drive plate 21 rises, and the conveyor belt 13 transports the bridge frame 6 to be welded forward. At this time, the pressure bar 214 and the pressure plate 215 are raised synchronously, and the welding gun 52 is raised. The welding gun 52 is in a higher position, which ensures that the crossbar 61 on the bridge frame 6 to be welded will not collide with the welding gun 52 during the transportation process, thus ensuring the safe operation of the equipment. At the same time, this process will also transport the welded crossbar 61 on the bridge frame 6 to be welded forward to the next station, and move the crossbar 61 to be welded on the bridge frame 6 to be welded to the bottom of the welding mechanism 5, in preparation for the next round of welding.

[0077] The reciprocating lifting and lowering of the drive plate 21 on the drive mechanism 2 can coordinate and synchronize the automatic placement of the crossbar 61, the conveying of the bridge frame 6 to be welded, and the welding process, effectively improving production efficiency.

[0078] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
