Abstract

This invention relates to the technical field of cable tray processing and discloses a welding device for cable trays, including a base plate with several robotic arms mounted on it. A base is fixedly mounted on the upper side of the base plate, and several grooves are formed on the upper side of the base. A conveying device is set above the base. By driving a push plate back and forth with a cylinder, steel pipes can be moved to an inclined plate in batches. The conveying device can then move the flexible strips along a conveyor belt, moving the steel pipes to the left one by one. When a steel pipe reaches the first groove, it falls into the groove. Subsequent steel pipes will move from above the first steel pipe into the next groove. This process moves the steel pipes into each groove one by one, allowing each steel pipe to be fitted with an L-shaped plate for welding. This allows for automatic placement of steel pipes, so workers only need to insert the L-shaped plate, thus reducing the workload of the workers.

Description

Technical Field

[0001] This invention relates to the technical field of cable tray processing, specifically to a welding device for cable trays. Background Technology

[0002] Cable trays are categorized into trough, tray, ladder, and mesh structures, and consist of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors, the trays consist of two L-shaped plates and several steel pipes, requiring welding between the L-shaped plates and the pipes. While existing technologies utilize robotic arms with welding guns, workers still need to manually position and place each pipe before welding, resulting in a significant workload and reduced efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a welding device for cable trays, which has the advantages of requiring only the insertion of L-shaped plates by workers, thus reducing their workload. It also solves the problem that workers need to position and place several steel pipes one by one before welding, which results in a large workload and affects work efficiency.

[0004] To achieve the goal of reducing the workload of workers by simply inserting the L-shaped plate, the present invention provides the following technical solution: a welding device for cable trays, comprising a base plate, several robotic arms mounted on the base plate, a base fixedly mounted on the upper side of the base plate, several grooves formed on the upper side of the base, a conveying device above the base, two sets of flexible strips fixedly mounted on the conveyor belt of the conveying device, two support frames fixedly mounted on the base, both support frames being fixedly connected to the outer shell of the conveying device, and an inclined block fixedly mounted on the base, with a fixed... An inclined plate is installed, and an inclined box is installed on the inclined plate. A discharge chute is opened on the front of the inclined box. Cylinders a are fixedly installed on both the left and right sides of the inclined box. Connecting blocks a are fixedly installed on the output shafts of the two cylinders a. Connecting blocks b are fixedly installed on the two connecting blocks a. Push plates are fixedly installed on the lower side of the two connecting blocks b. The push plates move through the rear wall of the inclined box. Two vertical plates are set on the bottom plate. Several connecting parts are fixedly installed on the two vertical plates. Two long plates are set between the two vertical plates. The two long plates are fixedly connected to the two vertical plates respectively. Support legs are fixedly installed on the inclined box, the inclined blocks, and the inclined plate.

[0005] Preferably, baffles are fixedly installed on both the front and rear sides of the inclined block, and top plates are fixedly installed on the two baffles. Two cylinders b are fixedly installed on the upper side of the top plates. Connecting strips are fixedly installed at the front ends of the output shafts of the two cylinders b. Two blocking strips are fixedly installed on the two connecting strips. The four blocking strips all movably pass through the baffle in front of the two baffles.

[0006] Preferably, two base blocks are fixedly installed on the upper side of the base plate, and several fixed frames are fixedly installed on the upper side of each base block. Each fixed frame is movably connected to a movable strip, and each movable strip is fixedly connected to two vertical plates respectively.

[0007] Preferably, two mounting strips are fixedly installed on each of the two base blocks, and a cylinder c is fixedly installed on each mounting strip. Pressure plates are fixedly installed on the output shafts of the four cylinders c, and the four pressure plates are respectively connected to the two vertical plates.

[0008] Preferably, a small rod is fixedly installed on each pressure plate, a sleeve is movably sleeved on each small rod, a circular plate is fixedly installed on each sleeve, a pressure spring is fixedly installed on each circular plate, and each pressure spring is fixedly connected to each pressure plate.

[0009] Preferably, each of the sleeves has a limiting groove on its inner sidewall, and a limiting ring is movably connected in each limiting groove. Each limiting ring is fixedly sleeved on each small rod.

[0010] Preferably, a square plate is fixedly installed on the right side of each of the two vertical plates, and the two square plates are fixedly connected to the two long plates respectively. A trapezoidal strip is fixedly installed on the left side of each of the two vertical plates.

[0011] Compared with the prior art, the present invention provides a welding device for cable trays, which has the following advantages:

[0012] This cable tray welding device works by inserting an L-shaped plate into the gap between the vertical and long plates, placing steel pipes into the inclined box, and using two cylinders to move a push plate forward to push the bottom steel pipe in the inclined box onto the inclined plate. The cylinders then move the push plate back and forth to move the steel pipes onto the inclined plate in batches. The steel pipes then roll along the inclined plate and onto the base. A conveyor belt then moves the flexible strip, moving the steel pipes one by one to the left. When a steel pipe reaches the first groove, it falls into it. Subsequent steel pipes move from above the first pipe into the next groove, thus moving each steel pipe into each groove individually. This allows each steel pipe to be fitted with the L-shaped plate for welding. This automatic placement of the steel pipes reduces the workload for workers, as they only need to insert the L-shaped plate.

[0013] The cable tray uses a welding device. The steel pipes that roll onto the inclined block via the inclined plate are blocked by the right-hand blocking bar. After cylinder B moves the right-hand blocking bar forward, the steel pipe moves to the left-hand blocking bar and is blocked. Then, cylinder B moves the right-hand blocking bar backward to block subsequent steel pipes. In this way, when a steel pipe needs to be placed, cylinder B moves the left-hand blocking bar forward, which can roll the steel pipe on the inclined block to the left onto the base. This allows control over the number of steel pipes that move to the base each time.

[0014] The cable tray uses a welding device. With the support of a fixed frame and movable bars, the vertical plates can move back and forth. When conveying steel pipes, the cylinder C drives the vertical plates to move away from each other, so that the steel pipes can be conveyed smoothly. After the steel pipes enter each groove, the cylinder C drives the two vertical plates to move closer to each other, so that the two L-shaped plates can clamp the steel pipes, thus making it easy to fit the L-shaped plates and steel pipes together for welding.

[0015] The welding device for this cable tray uses the pressure and resilience of the pressure spring to move the two vertical plates closer together when the cylinder C clamps the steel pipe. This allows the L-shaped plate to contact the steel pipe while avoiding excessive pressure that could damage the L-shaped plate and the steel pipe.

[0016] 5. The welding device for this cable tray can facilitate the movement of the two vertical plates away from each other by the cylinder c through the limiting ring and the limiting groove. At the same time, it can avoid damage caused by excessive stretching of the pressure spring. The square plate can block and position the L-shaped plate, and the trapezoidal strip can guide the L-shaped plate when it is inserted. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, wherein the same parts are indicated by the same reference numerals. It should be noted that the terms “front”, “rear”, “left”, “right”, “upper” and “lower”, “bottom surface” and “top surface” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific part, respectively.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7The present invention provides a technical solution: a welding device for cable trays, comprising a base plate 1, on which a plurality of robotic arms 38 are mounted, and welding guns are mounted on the robotic arms 38. A base 4 is fixedly mounted on the upper side of the base plate 1, and a plurality of grooves 23 are formed on the upper side of the base 4. A conveying device 22 is arranged above the base 4, and two sets of flexible strips 24 are fixedly mounted on the conveyor belt of the conveying device 22. Two support frames 6 are fixedly mounted on the base 4, and both support frames 6 are fixedly connected to the outer shell of the conveying device 22. An inclined block 15 is fixedly mounted on the base 4, and an inclined plate 16 is fixedly mounted on the inclined block 15. An inclined box 20 is installed on the 16. The inclined box 20 has a discharge chute 19 on its front. Cylinders a21 are fixedly installed on both the left and right sides of the inclined box 20. Connecting blocks a25 are fixedly installed on the output shafts of the two cylinders a21. Connecting blocks b26 are fixedly installed on the two connecting blocks a25. Push plates 18 are fixedly installed on the lower side of the two connecting blocks b26. The push plates 18 move through the rear wall of the inclined box 20. Two vertical plates 8 are provided on the bottom plate 1. Several connecting pieces 2 are fixedly installed on the two vertical plates 8. Two long plates 3 are provided between the two vertical plates 8. The two long plates 3 are fixedly connected to the two vertical plates 8 respectively. Support legs 17 are fixedly installed on the inclined box 20, inclined block 15, and inclined plate 16. By inserting the L-shaped plate into the gap between the vertical plate 8 and the long plate 3, the steel pipe is placed into the inclined box 20. The steel pipe at the bottom of the inclined box 20 is pushed onto the inclined plate 16 by the two cylinders a21 driving the push plate 18 forward. The steel pipe is moved onto the inclined plate 16 batch by batch by the cylinder driving the push plate 18 back and forth. In this way, the steel pipe will roll along the inclined plate 16 and inclined block 15 to the base 4. Then the conveyor device 22 can move the flexible strip 24 through the conveyor belt and move the steel pipe to the left one by one. The cable tray moves as follows: when the steel pipe moves to the first groove 23, it will fall into the groove 23. Subsequent steel pipes will move from above the first steel pipe into the next groove 23. In this way, the steel pipes can be moved into each groove 23 one by one, so that each steel pipe can be attached to the L-shaped plate for welding. The steel pipes can be placed automatically, and the workers only need to insert the L-shaped plate, which reduces the workload of the workers. After welding is completed, the cable tray is moved upward. When the steel pipe is separated from the groove 23, the flexible strip 24 can be bent and deformed, and the user can pull out the cable tray.

[0028] Both sides of the inclined block 15 are fixedly equipped with baffles 14. A top plate 27 is fixedly installed on each baffle 14. Two cylinders b30 are fixedly installed on the upper side of the top plate 27. Connecting bars 28 are fixedly installed at the front ends of the output shafts of both cylinders b30. Two blocking bars 29 are fixedly installed on each connecting bar 28. All four blocking bars 29 movably pass through the front baffle 14. Steel pipes rolling onto the inclined block 15 via the inclined plate 16 are blocked by the right-hand blocking bar 29. After the cylinder b30 moves the right-hand blocking bar 29 forward, the steel pipe moves to the left-hand blocking bar 29 and is blocked. Then, the cylinder b30 moves the right-hand blocking bar 29 backward to block subsequent steel pipes. This process is repeated when needed. When placing a steel pipe, cylinder b30 moves the left-side blocking bar 29 forward, causing the steel pipe on the inclined block 15 to roll to the left onto the base 4. This allows control over the number of steel pipes that move onto the base 4 each time. Since the pusher plate 18 moves back and forth, pushing the steel pipes onto the inclined plate 16 until it is full will cause the steel pipes on the front inclined plate 16 to be pushed off. Therefore, cylinder a21 needs to be controlled separately. Two base blocks 7 are fixedly installed on the upper side of the base plate 1. Several fixed frames 10 are fixedly installed on the upper side of each base block 7. Each fixed frame 10 has a movable strip 9 connected to it. Each movable strip 9 is fixedly connected to two vertical plates 8. Two mounting strips 11 are fixedly installed on each of the two base blocks 7. Each mounting strip 11 has... Each of the four cylinders 31 is fixedly installed with a cylinder c12. Pressure plates 31 are fixedly installed on the output shafts of each cylinder c12. The four pressure plates 31 are respectively connected to two vertical plates 8. Supported by a fixed frame 10 and a movable bar 9, the vertical plates 8 can move back and forth. When conveying steel pipes, the cylinders c12 drive the vertical plates 8 to move away from each other, allowing the steel pipes to be conveyed smoothly. When the steel pipe enters each groove 23, the cylinders c12 drive the two vertical plates 8 to move closer together, causing two L-shaped plates to clamp the steel pipe, thus facilitating welding by fitting the L-shaped plates to the steel pipe. Each pressure plate 31 is fixedly installed with a small rod 35, and each small rod 35 is movably fitted with a sleeve 33. Each sleeve 33 has... A circular plate 34 is fixedly installed, and a pressure spring 32 is fixedly installed on each circular plate 34. Each pressure spring 32 is fixedly connected to each pressure plate 31. The pressure and toughness of the pressure spring 32 can ensure that when the cylinder c12 drives the two vertical plates 8 to move closer to each other to clamp the steel pipe, the L-shaped plate can contact the steel pipe while avoiding excessive pressure that could damage the L-shaped plate and the steel pipe. Each sleeve 33 has a limit groove 36 on its inner side wall, and a limit ring 37 is movably connected in each limit groove 36. Each limit ring 37 is fixedly sleeved on each small rod 35. A square plate 13 is fixedly installed on the right side of each of the two vertical plates 8, and the two square plates 13 are fixedly connected to the two long plates 3. A trapezoidal strip 5 is fixedly installed on the left side of each of the two vertical plates 8.The limiting ring 37 and the limiting groove 36 facilitate the movement of the two vertical plates 8 away from each other by the cylinder c12, while preventing damage to the pressure spring 32 due to excessive stretching. The square plate 13 blocks and positions the L-shaped plate, and the trapezoidal strip 5 provides guidance when inserting the L-shaped plate.

[0029] In use, the first step is to insert the L-shaped plate into the gap between the vertical plate 8 and the long plate 3, and then place the steel pipe into the inclined box 20. Two cylinders a21 drive the pusher plate 18 forward, pushing the bottom steel pipe in the inclined box 20 onto the inclined plate 16. The cylinders then drive the pusher plate 18 back and forth, moving the steel pipes one batch at a time onto the inclined plate 16. The steel pipes then roll along the inclined plate 16 and the inclined block 15 onto the base 4. The conveyor device 22 then uses a conveyor belt to move the flexible strip 24, moving the steel pipes one by one to the left. When the steel pipe reaches... When the first steel pipe falls into the first groove 23, the subsequent steel pipes will move from above the first steel pipe into the next groove 23. In this way, the steel pipes can be moved into each groove 23 one by one, so that each steel pipe can be attached to the L-shaped plate for welding. This allows for automatic placement of the steel pipes, and the workers only need to insert the L-shaped plate, which reduces the workload of the workers. After welding is completed, the cable tray is moved upward. When the steel pipe separates from the groove 23, the flexible strip 24 can be bent and deformed, and the user can pull out the cable tray.

[0030] Step 2: The steel pipe that rolls onto the inclined block 15 via the inclined plate 16 will be blocked by the right-hand blocking bar 29. After the cylinder b30 moves the right-hand blocking bar 29 forward, the steel pipe will move to the left-hand blocking bar 29 and be blocked. Then, the cylinder b30 moves the right-hand blocking bar 29 backward to block subsequent steel pipes. In this way, when it is necessary to place a steel pipe, the cylinder b30 moves the left-hand blocking bar 29 forward to roll the steel pipe on the inclined block 15 to the left onto the base 4. This allows control over the number of steel pipes that move to the base 4 each time.

[0031] Step 3: With the support of the fixed frame 10 and the movable strip 9, the vertical plate 8 can move back and forth. When the steel pipe is being transported, the cylinder c12 drives the vertical plate 8 to move away from each other, so that the steel pipe can be transported smoothly. When the steel pipe enters each groove 23, the cylinder c12 drives the two vertical plates 8 to move closer to each other, so that the two L-shaped plates can clamp the steel pipe, thus making it easy to fit the L-shaped plates and the steel pipe for welding.

[0032] Step 4: The pressure and toughness of the pressure spring 32 can move the two vertical plates 8 towards each other when the cylinder c12 drives them to clamp the steel pipe. This allows the L-shaped plate to come into contact with the steel pipe while avoiding excessive pressure that could damage the L-shaped plate and the steel pipe.

[0033] Step 5: The limiting ring 37 and the limiting groove 36 can facilitate the cylinder c12 to drive the two vertical plates 8 to move away from each other, while avoiding damage caused by excessive stretching of the pressure spring 32. The square plate 13 can block and position the L-shaped plate, and the trapezoidal strip 5 can guide the L-shaped plate when it is inserted.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
