[0002] Cable supports are structural components used to support, fix, and protect cables. They are widely used in power plants, substations, industrial and mining enterprises, urban underground utility tunnels, tunnels, and building interiors, and are an indispensable part of cable laying systems.

[0003] As shown in Figure 1, a conventional cable bracket is welded from mutually perpendicular angle steel. Multiple shorter angle steels are welded to the angle steel, which is fixedly installed on a wall or other supporting surface, to support the cables. The ends of these cable-supporting angle steels are designed to curve upwards to prevent the cables from slipping. Currently, the welding of cable brackets typically involves a large amount of manual labor. For example, the angle steels need to be manually positioned and then welded, resulting in low welding efficiency and difficulty in ensuring weld consistency. Summary of the Invention

[0016] Example 1: As shown in Figures 1-2, this invention proposes an automatic loading and unloading cable bracket welding device. The cable bracket includes a mounting angle steel 1 and multiple supporting angle steels 2 welded to the mounting angle steel 1. The mounting angle steel 1 is used to fix itself to a wall or other supporting surface. Multiple oblong holes are provided on the mounting angle steel 1, allowing for a certain degree of positional adjustment. The end of each supporting angle steel 2 away from the mounting angle steel 1 has an upward tilt. The welding device includes a flipping mechanism, an L-shaped support plate 8 slidably mounted vertically on the flipping mechanism, a U-shaped operating platform 20 located on one side of the L-shaped support plate 8, and a belt conveyor 12 located below the U-shaped operating platform 20. Multiple mounting angle steels 1 are placed equidistantly on the belt conveyor 12. After the L-shaped support plate 8 moves to its lowest point, the belt conveyor 12 transports one mounting angle steel 1 onto the L-shaped support plate 8. Multiple supporting angle steel conveying mechanisms are provided on the U-shaped operating platform 20 to push multiple supporting angle steels 2 into contact with the mounting angle steels 1, entering the welding position. The U-shaped operating table 20 is equipped with a welding robot 33, which performs automated welding according to a pre-set welding program. During operation, the L-shaped support plate 8 first moves to the lowest point, receives the installation angle steel 1 from a belt conveyor 12, and then moves to a position near the highest point and stops. Then, the support angle steel conveying mechanism conveys multiple support angle steels 2 to a position near the welding position and stops. Next, the L-shaped support plate 8 rises to the highest point, and the support angle steel conveying mechanism continues to convey the support angle steels 2 to the welding position. At this time, the installation angle steel 1 and the support angle steel 2 are in complete contact and enter the welding state. After welding by the welding robot 33, the flipping mechanism starts to flip, causing the welded cable bracket to rotate more than 90 degrees. Under its own gravity, it falls from the L-shaped support plate 8 onto the prepared receiving rack or conveyor line, completing the automatic unloading. The receiving rack and conveyor line are not shown in the figure because they only need to complete the receiving work and are conventional structures, which are not the focus of this application.

[0017] Example 2; As shown in Figures 2 and 5, the present invention proposes an automatic loading and unloading cable bracket welding equipment. Compared with Example 1, this example details the structure of the flipping mechanism. Specifically, the flipping mechanism includes a flipping frame 3, a lifting plate 7 slidably disposed on the flipping frame 3 in the vertical direction, a lifting device 19 disposed at the bottom of the flipping frame 3 and driving the lifting plate 7 to rise and fall, and a power component for driving the flipping frame 3 to flip; an L-shaped support plate 8 is slidably disposed on the lifting plate 7 in the horizontal direction; specifically, multiple sliding guide plates are vertically disposed on the flipping frame 3, and multiple sliding grooves that cooperate with the sliding guide plates are disposed on the lifting plate 7; the lifting device 19 is a cylinder, a hydraulic cylinder, or an electric push rod.

[0018] Multiple guide rails 9 are horizontally arranged on the lifting plate 7. The bottom of the L-shaped support plate 8 is slidably connected to the guide rails 9. A fixed plate is arranged on the lifting plate 7. A damping rod 11 and a transverse spring 10 are arranged between the fixed plate and the L-shaped support plate 8. In an optional embodiment, the transverse spring 10 is sleeved on the outside of the damping rod 11. Two transverse springs 10 and two damping rods 11 are provided.

[0019] Multiple baffles 13 are equidistantly arranged on the belt conveyor 12. The mounting angle steel 1 can be placed on the belt and positioned between two baffles 13. Precise placement is not required because during feeding, the mounting angle steel 1 will first fall onto the L-shaped support plate 8. Then, the baffles 13 will push the mounting angle steel 1 to continue moving on the L-shaped support plate 8. After the baffles 13 have completely pushed the mounting angle steel 1 onto the L-shaped support plate 8, they will continue to push the L-shaped support plate 8 to move. After the baffles 13 rotate and move away, the L-shaped support plate 8 will slowly move back under the action of the transverse spring 10 and the damping rod 11.

[0020] The power assembly includes a support base 4, a motor 5 and a reducer 6 mounted on the support base 4, and a rotating shaft mounted on the bottom end face of the tilting frame 3 facing away from the lifting plate 7. The output end of the motor 5 is connected to the input end of the reducer 6, and the output end of the reducer 6 is connected to the rotating shaft.

[0021] Furthermore, a rotating rod 15 is rotatably mounted on the L-shaped support plate 8, and multiple grippers 14 are mounted on the rotating rod 15. The grippers 14 flip and clamp the mounting angle steel 1. A power device 16 that drives the rotating rod 15 to rotate is mounted on the L-shaped support plate 8. In an optional embodiment, the power device 16 includes a protective cover mounted on the L-shaped support plate 8, and a motor and a reducer located inside the protective cover. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating rod 15.

[0022] Furthermore, an extension device 17 is provided at one end of the L-shaped support plate 8, and a push plate 18 is provided at the extension end of the extension device 17. The push plate 18 pushes the installation angle steel 1 into the welding position to realize the position calibration of the installation angle steel 1. The extension device 17 is a cylinder, hydraulic cylinder or electric push rod. In order to avoid welding sparks affecting the extension device 17, a protective cover can be provided outside the extension device 17.

[0023] Example 3; As shown in Figures 2-5, this invention proposes an automatic loading and unloading cable bracket welding device. Compared to Example 2, this example details the structure of the supporting angle steel pushing mechanism. Specifically, the supporting angle steel pushing mechanism includes a guide trough 21 set on the top of the U-shaped operating platform 20, a pushing plate 26 slidably set in the guide trough 21, a rodless cylinder 29 set on the inner wall of the top of the U-shaped operating platform 20 and driving the pushing plate 26 to move, and a supporting angle steel stacking box 22 set on the U-shaped operating platform 20 to drop one supporting angle steel 2 at a time. Specifically, the width of the guide trough 21 needs to be greater than the overall width of the supporting angle steel 2 plus the end protrusion. A guide structure is set on the side of the guide trough 21 near the L-shaped support plate 8 so that the actual width of the guide trough 21 is reduced so that the supporting angle steel 2, excluding the protrusion, can pass through, thereby realizing the guiding and positioning function of the supporting angle steel 2; the supporting angle steel stacking box 22 comprises two parts: one part accommodates the upturned end of the supporting angle steel 2, and the other part accommodates the rest of the supporting angle steel 2. The part accommodating the upturned end can restrict the supporting angle steel 2, allowing it to be stacked stably upwards. The top surface of the push plate 26 is lower than the highest point of the supporting angle steel 2, and the length of the push plate 26 needs to be greater than the overall length of the supporting angle steel 2. In this way, when the push plate 26 pushes one supporting angle steel 2, another supporting angle steel 2 will fall onto the push plate 26. After the push plate 26 returns to its original position, the next supporting angle steel 2 will fall into the guide trough 21. In an optional embodiment, a U-shaped plate 28 is provided on the inner wall of the top of the U-shaped operating table 20, and a rodless cylinder 29 is provided inside the U-shaped plate 28. A connecting frame 27 is provided at the tail of the push plate 26, and a clearance groove is provided at the bottom of the guide trough 21 for the connecting frame 27 to pass through. The connecting frame 27 is connected to the sliding part of the rodless cylinder 29.

[0024] Furthermore, a guide plate 25 is provided on the outside of the supporting angle steel stacking box 22, and a guide hole is provided on the guide plate 25. A guide rod 23 is vertically provided on the U-shaped operating platform 20. The top of the guide rod 23 is inserted into the guide hole. A vertical spring 24 is sleeved on the guide rod 23. The two ends of the vertical spring 24 are respectively connected to the U-shaped operating platform 20 and the guide plate 25. A follower frame 30 is provided on the push plate 26, and multiple arc-shaped protrusions 31 are provided on the follower frame 30. A support rod 32 is provided on the supporting angle steel stacking box 22. During the movement of the push plate 26, the contact between the arc-shaped protrusions 31 and the support rod 32 continuously drives the supporting angle steel stacking box 22 to vibrate up and down within a small range, ensuring smooth material dropping.

[0025] In summary, when using this invention, the lifting device 19 moves the L-shaped support plate 8 to the lowest point, receives the installation angle steel 1 from the belt conveyor 12, and then moves it to a position near the highest point and stops. During the movement, the telescopic device 17 pushes the installation angle steel 1 through the push plate 18 to perform position calibration. Then, the support angle steel conveying mechanism transports multiple support angle steels 2 to a position near the welding position and stops. Next, the L-shaped support plate 8 rises to the highest point, and then the push plate 26 continues to transport the support angle steel 2 to the welding position. At this time, the installation angle steel 1 and the support angle steel 2 are in complete contact and enter the welding state. The power device 16 starts and clamps the installation angle steel 1 through the gripper 14 to ensure that the position remains unchanged during the welding process. After welding by the welding robot 33, the motor 5 starts, causing the welded cable bracket to rotate more than 90 degrees. In this embodiment, the rotation angle is 135°. The gripper 14 flips in the opposite direction and releases. Under its own gravity, the cable bracket falls from the L-shaped support plate 8 onto the prepared receiving rack or conveyor line, completing the automatic unloading. In this invention, both the installation angle steel 1 and the support angle steel 2 automatically enter the welding position for automatic welding, and then the automatic material is discharged by flipping through the flipping mechanism. The only manual interventions in the whole process are stacking the support angle steel 2 in the support angle steel stacking box 22 and placing the installation angle steel 1 on the belt conveyor line 12. Manual operation does not affect the automatic welding process, resulting in high welding efficiency and good welding consistency.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
