Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a cable tray welding device. Background Technology

[0002] With the rapid development of modern industry, cable trays have been widely used in many fields such as power, communication, and construction. As a structural component used to support and protect cables, wires, etc., the quality and production efficiency of cable trays are crucial to the stable operation of the entire engineering system.

[0003] Traditional cable tray welding processes mostly rely on manual operation, where each component of the cable tray, such as crossbeams and longitudinal beams, is welded and spliced ​​one by one. This method requires workers to have high welding skills and experience.

[0004] However, both traditional manual welding and semi-automatic welding equipment have gradually revealed some limitations in the face of the growing market demand for cable trays. On the one hand, labor costs are constantly rising, and the welding method that relies on a large number of manual operations makes the production cost of cable trays remain high. Moreover, when encountering cable tray components of different sizes, the equipment adjustment time is long and cannot quickly adapt to diversified production needs. In view of this, we propose a cable tray welding device. Utility Model Content

[0005] The purpose of this invention is to provide a cable tray welding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cable tray welding device includes a body, a foot support at the bottom of the body, the foot support resting on a base plate, and a welding assembly at the top of the base plate, the welding assembly comprising:

[0008] A servo ring module is fixedly installed on the top of the base plate. A slider is slidably installed inside the servo ring module. A multi-axis robotic arm is fixedly installed on the top of the slider. A welding torch is provided at the end of the multi-axis robotic arm away from the slider.

[0009] A servo stepping hydraulic cylinder is fixedly installed on the top of the machine body. The piston end of the servo stepping hydraulic cylinder is fixedly connected to the outer center of an L-shaped plate. Two sets of servo stepping hydraulic cylinders and L-shaped plates are provided, and the two sets of servo stepping hydraulic cylinders and L-shaped plates are mirror images of each other at the left and right ends of the machine body. U-shaped frames are fixedly installed at both ends of the top of the machine body. Guide rods are fixedly installed on the inner side of the U-shaped frames. The L-shaped plates slide against the outer side of the guide rods. Two sets of U-shaped frames and guide rods are provided, and the two sets of U-shaped frames and guide rods are symmetrically arranged at the front and rear ends of the machine body.

[0010] The L-shaped plate has two sets of longitudinal beams attached to its inner side, and a crossbeam is attached between the two sets of longitudinal beams. The crossbeam has multiple sets. The longitudinal beams and crossbeams form the cable tray body. A fixing block is fixedly installed on the inner side of the bottom end of the L-shaped plate. The top of the fixing block is set as an inclined surface. Multiple sets of fixing blocks and inclined surfaces are arranged on a single set of L-shaped plates, and the multiple sets of fixing blocks and inclined surfaces are arranged in a linear array with equal spacing.

[0011] Preferably, a metal mesh is snapped into the inner side of the center of the top of the machine body.

[0012] Preferably, a roller is rotatably mounted on the inner side of the bottom end of the L-shaped plate. The roller rolls against the upper surface of the bottom end of the U-shaped frame. Two sets of rollers are provided on a single set of L-shaped plates, thereby making the movement of the L-shaped plate more stable.

[0013] Preferably, an inclined plate is fixedly installed on the top of the L-shaped plate to effectively intercept welding debris.

[0014] Preferably, a protective cover is fixedly installed at the center of the outer side of the top of the L-shaped plate to prevent welding debris from flying towards the servo stepping hydraulic cylinder, effectively protecting the servo stepping hydraulic cylinder. The protective cover and the servo stepping hydraulic cylinder are in the same vertical plane, and the movement trajectory of the protective cover does not intersect with the multi-axis robotic arm to prevent motion interference.

[0015] Preferably, an auxiliary component is provided at the top of the base plate. The auxiliary component includes a dust pump. The dust pump is fixedly installed at the top of the base plate. One end of the dust suction pipe is fixedly installed at the input end of the dust pump. The output end of the dust pump is connected to an external processing device. The other end of the dust suction pipe is fixedly connected to the bottom of a conical cover. The conical cover is fixedly installed at the center of the inner side of the top of the machine body. The conical cover is located directly below the metal mesh, thereby effectively cleaning the debris generated during welding.

[0016] Compared with the prior art, the present invention provides a cable tray welding device, which has the following advantages:

[0017] 1. This cable tray welding device, in order to perform welding better, is equipped with welding components. When the servo ring module is activated, the multi-axis robotic arm can move in an arc around the machine body in conjunction with the slider, thereby enabling flexible multi-angle movement of the welding torch. The servo stepping hydraulic cylinder is activated, causing two sets of L-shaped plates to move laterally towards each other on the outside of the guide rod on the U-shaped frame, thereby fixing the cable tray body composed of longitudinal beams and transverse beams. This allows it to accommodate cable tray bodies of more sizes. The fixing block and inclined plane ensure that the debris generated during welding falls better onto the metal mesh. The rollers make the movement of the L-shaped plates more stable, and the inclined plate effectively intercepts debris. The protective cover prevents the welding debris from flying towards the servo stepping hydraulic cylinder.

[0018] 2. In order to better clean the debris generated during welding, the cable tray welding device is equipped with auxiliary components. When the dust pump is started, an airflow is generated downward towards the metal mesh through the dust suction pipe and the conical hood. The debris generated during welding falls through the metal mesh onto the conical hood and is then cleaned by the dust pump to the subsequent processing equipment, thereby better cleaning the debris generated during welding.

[0029] In one embodiment of this utility model, a welding assembly 4 is provided at the top of the base plate 3. The welding assembly 4 includes a servo ring module 41. The servo ring module 41 is fixedly installed at the top of the base plate 3. A slider 42 is slidably installed inside the servo ring module 41. A multi-axis robotic arm 43 is fixedly installed at the top of the slider 42. A welding torch 44 is provided at the end of the multi-axis robotic arm 43 away from the slider 42. When the servo ring module 41 is activated, it can drive the multi-axis robotic arm 43 to perform arc-shaped movements around the machine body 1 in conjunction with the slider 42.

Two sets of U-shaped frames 47 and guide rods 48 are arranged, and the two sets of U-shaped frames 47 and guide rods 48 are symmetrically arranged at the front and rear ends of the machine body 1. Longitudinal beams 49 are attached to the inner side of L-shaped plates 46. Two sets of longitudinal beams 49 are arranged. Crossbeams 410 are attached between the two sets of longitudinal beams 49. Multiple sets of crossbeams 410 are arranged. The longitudinal beams 49 and crossbeams 410 form the bridge frame body. When it is necessary to adjust the structure of the longitudinal beams 49 and crossbeams 410... When welding the assembled cable tray body, the longitudinal beams 49 are placed on the L-shaped plate 46, and the servo stepping hydraulic cylinder 45 is activated. Its piston end drives the L-shaped plate 46 to move laterally closer to each other on the guide rod 48 inside the U-shaped frame 47, placing the crossbeam 410 between the two sets of longitudinal beams 49, thereby fixing cable tray bodies of more sizes. A fixing block 411 is fixedly installed on the inner side of the bottom end of the L-shaped plate 46. The top of the fixing block 411 is set as an inclined surface 412. Multiple sets of fixing blocks 411 and inclined surfaces 412 are set on a single set of L-shaped plates 46, and multiple sets of fixing blocks 411 and inclined surfaces 412 are arranged in a linear array with equal spacing.

With the help of the fixing blocks 411 and inclined surfaces 412, the welding process can be controlled. The debris falls more effectively onto the metal mesh 413. Additionally, rollers 414 are rotatably mounted on the inner side of the bottom end of the L-shaped plate 46. These rollers 414 roll and adhere to the upper surface of the bottom end of the U-shaped frame 47, making the movement of the L-shaped plate 46 more stable.

[0031] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the servo ring module 41, multi-axis robotic arm 43, welding torch 44, servo stepping hydraulic cylinder 45, and dust pump 51.

The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0032] Working principle: When welding is required on the cable tray body composed of longitudinal beams 49 and crossbeams 410, the longitudinal beams 49 are placed on the L-shaped plate 46, and the servo stepping hydraulic cylinder 45 is activated. Its piston end drives the L-shaped plate 46 to move laterally closer to each other on the guide rod 48 inside the U-shaped frame 47, placing the crossbeams 410 between the two sets of longitudinal beams 49. This allows for the fixing of cable tray bodies of more sizes. The fixing block 411 and the inclined surface 412, combined with these, allow welding debris to fall better onto the metal mesh 413 and roll away. The wheel 414 rolls against the upper surface of the bottom end of the U-shaped frame 47, making the movement of the L-shaped plate 46 more stable. Then, the servo ring module 41 is activated, which, together with the slider 42, can drive the multi-axis robotic arm 43 to make arc movements around the body 1. With the multi-axis robotic arm 43 and the welding gun 44, it can perform flexible multi-angle movements to complete the welding operation of the bridge frame body. During the welding process, the inclined plate 415 can effectively intercept the debris and prevent it from splashing everywhere, while the protective cover 416 can prevent the welding debris from flying towards the servo stepping hydraulic cylinder 45.

[0033] Furthermore, during the welding process, in order to clean up the welding debris, the dust pump 51 is started. When the dust pump 51 is working, it generates a downward airflow towards the metal mesh 413 through the dust suction pipe 52 and the conical hood 53. The welding debris first falls through the metal mesh 413 onto the conical hood 53, and is then cleaned by the dust pump 51 to the subsequent processing equipment, thereby achieving effective cleaning of the welding debris.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
