[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This invention provides, for example Figures 1-11The welding device for cable trays shown includes a cable tray body 1, on which a rolling arrangement wheel 2 is mounted. Each end of the arrangement wheel 2 has a roller 21. A connecting assembly 3 is located on the top of the arrangement wheel 2, and a quantitative feeding machine 4 is located on the top of the connecting assembly 3. The quantitative feeding machine 4 has a feed inlet on its top and multiple supports 11 inside its cavity. Through the rolling interaction between the arrangement wheel 2 and the cable tray body 1, combined with the quantitative feeding machine 4, automatic conveying of the supports 11 is achieved. Compared to traditional manual operation, this significantly improves the conveying efficiency of the supports 11 and reduces manpower input.

[0035] Both ends of the roller 21 are equipped with rollers 20 that fit against the cable tray body 1. Multiple spot welding assemblies 22 are connected and inserted into the outer wall of the roller 21. One end of each spot welding assembly 22 is mounted on the arrangement wheel 2, and the other end of each assembly has a locking member 23 that engages with the bracket 11. Multiple locking members 23 are provided. The fit between the rollers 20 and the cable tray body 1 ensures the stability of the arrangement wheel 2's rolling. Simultaneously, the engagement of the spot welding assemblies 22 and the locking members 23 allows the bracket 11 to be accurately engaged and welded during transport, improving the installation accuracy and stability of the bracket 11.

[0036] Furthermore, the inner cavity of the roller 21 is provided with multiple steel balls 211. The arrangement of the steel balls 211 provides gravity-driven conditions for automated spot welding, eliminating the need for additional complex control equipment, simplifying the operation process, reducing equipment costs, and improving the automation level of the welding device.

[0037] Furthermore, the spot welding assembly 22 includes a channel 221, one end of which is connected to the outer wall of the roller 21. A telescopic rod 222 is inserted into the inner cavity of the channel 221. One end of the telescopic rod 222 is provided with a force-bearing plate 223. Two symmetrically arranged support rods 224 are provided on one side of the force-bearing plate 223. The other end of the support rods 224 is provided with a sleeve plate 225. Multiple first springs are connected between the sleeve plate 225 and the force-bearing plate 223. Multiple welding heads 226 are provided on one side of the sleeve plate 225. A fixing block is provided on the side wall of one end of the welding head 226. A linkage sensor 227 that cooperates with the clamp 23 is provided on one side of the fixing block. A pulley is provided at one end of the linkage sensor 227. This structural design of the spot welding assembly 22, through the linkage of various components, enables the welding head 226 to accurately contact the bracket 11 and the cable tray body 1 to complete spot welding, ensuring welding quality. Moreover, the pulley reduces friction between the linkage sensor 227 and other components, improving the smoothness of the device operation.

[0038] Furthermore, a mounting rod 228 slides through the center of the sleeve 225. The mounting rod 228 is U-shaped, with both ends mounted on the sidewalls of the arrangement wheel 2. One end of the mounting rod 228 is connected to a limiting plate 229. Both sides of the limiting plate 229 have limiting grooves that mate with the clamping piece 23. A second spring is provided inside the limiting groove, and the other end of the second spring is connected to the clamping piece 23. The cooperation between the mounting rod 228 and the limiting plate 229 provides a stable space for the clamping piece 23 to move. The second spring ensures that the clamping piece 23 reliably clamps and releases the bracket 11, making the installation process of the bracket 11 more stable and orderly.

[0039] Furthermore, the clamping component 23 includes an extension rod 231, one end of which is connected to the side wall of the mounting rod 228. A hinge rod 232 is hinged to the extension rod 231, one end of which is arc-shaped, and the other end of which is connected to a clamping rod 233. One end of the clamping rod 233 is connected to the inner side wall of the limiting groove via a second spring. This clamping component 23's structural design, utilizing the characteristics of hinges and springs, enables flexible clamping and releasing of the bracket 11, adapting to the installation requirements of brackets 11 of different specifications and improving the versatility of the device.

[0040] Furthermore, one end of the clamping rod 233 is provided with a locking tooth that mates with the bracket 11, and both sides of the bracket 11 are provided with grooves that mate with the locking tooth. The engagement of the locking tooth and the grooves enhances the clamping force of the clamping member 23 on the bracket 11, ensuring that the bracket 11 will not fall off during transportation and welding, and improving the reliability of the bracket 11 installation.

[0041] Furthermore, both sides of the quantitative feeder 4 are equipped with fixing parts 41, and the inner cavity of each fixing part 41 is threadedly connected to a threaded transmission rod. One end of the transmission rod is connected to the power output end of the drive equipment. By driving the threaded transmission rod to rotate through the drive equipment, the horizontal position movement of the quantitative feeder 4 can be precisely controlled, thereby achieving precise adjustment of the conveying position of the support 11, meeting the needs of different installation scenarios, and improving the adaptability of the device.

[0042] Furthermore, the bottom of the quantitative feeding machine 4 is provided with a discharge port that matches the position of the spot welding assembly 22. The precise matching between the discharge port and the position of the spot welding assembly 22 ensures that the bracket 11 can be smoothly transported from the quantitative feeding machine 4 to the spot welding position, realizing a seamless connection between the transport of the bracket 11 and the welding process, and improving the overall work efficiency.

[0043] Working principle:

[0044] The first step is to drive the threaded transmission rod to rotate through the drive equipment, and the interaction between the threads will drive the quantitative feeding machine 4 to move horizontally. The roller 20 rolls on the top of the cable tray body 1, driving the arrangement wheel 2 to roll.

[0045] The second step is that the quantitative feeding machine 4 feeds the material according to the rotation of the arrangement wheel 2, and sends the bracket 11 in the inner cavity of the quantitative feeding machine 4 from the discharge port into the space between the two clamping rods 233. The elastic force of the second spring contracts and pulls the teeth on the clamping rods 233 to engage with the grooves on both sides of the bracket 11, thereby clamping the bracket 11. The rotation of the arrangement wheel 2 is used to lay the bracket 11 at equal intervals.

[0046] During the process, when the bracket 11 rotates to the center of the bottom end of the arrangement wheel 2, multiple steel balls 211 located in the inner cavity of the roller 21 roll into the inner cavity of the channel 221 under the influence of weight, and push the telescopic rod 222 to move to the bottom. The telescopic rod 222 pushes the force plate 223 to squeeze the first spring, and pushes the support rod 224, sleeve plate 225, welding head 226 and linkage sensor 227 to move synchronously. At this time, when the linkage sensor 227 moves, it contacts the top of the hinge rod 232 and squeezes one end of the hinge rod 232, so that the hinge rod 232 rotates at the hinge point with the extension rod 231, stretching the second spring. At this time, the two clamping rods 233 release the clamp on the bracket 11, and the bracket 11 is placed at the bottom of the inner cavity of the bracket 11 after being released from the clamp.

[0047] At the same time, the welding ends of the two welding heads 226 simultaneously contact the inner sidewalls of the bracket 11 and the cable tray body 1, and spot weld, so that the bracket 11 and the cable tray body 1 are initially fixed in position by spot welding; compared with the traditional manual placement and mechanical fixing methods, the spot welding fixation achieved at the same time as placement has strong fixation, and the spot welding fixation is performed at the same time as the bracket 11, which has high fixing efficiency and speed. Secondly, the bracket 11 is placed by rolling the arrangement wheel 2, which can improve the placement efficiency of the bracket 11, and the placement distance will not have dimensional deviation.

[0048] The third step is to reinforce and weld the cable tray body 1 after the bracket 11 has been fixedly placed.

[0049] It should be noted that personnel can modify the placement brackets 11 of different specifications and distances by changing the size of the arrangement wheels 2, so as to improve the adaptability and practicality of the equipment.

[0050] The steel ball 211 automatically enters the channel 221 under the action of gravity, pushing the welding head 226 to achieve spot welding, which improves the automation level of the equipment. No personnel or control equipment are required to operate during this process, which simplifies the operation process and can improve welding efficiency.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
