Description

Technical Field

[0001] This utility model belongs to the technical field of aerial work platforms, specifically relating to a welding device for the boom of an aerial work platform. Background Technology

[0002] Aerial work platforms are mobile work platforms used for various industries, including high-altitude operations, equipment installation, and maintenance. The main types of aerial work platforms include: scissor lifts, trailer-mounted aerial work platforms, articulated boom lifts, telescopic boom lifts, aluminum alloy aerial work platforms, telescopic boom lifts, and spider lifts. The booms of aerial work platforms are made of metal, and the manufacturing process typically involves welding, grinding, and polishing.

[0003] Domestic utility model patent application number 202122718622.6 discloses a welding device for a boom assembly. The welding device includes a mounting bracket, a welding device, and a flipping device. The welding device is movably mounted on the mounting bracket along its length. The flipping device includes a flipping seat and a flipping mechanism mounted on the flipping seat for driving the boom cylinder to flip. The flipping seat forms a flipping space for the boom cylinder to flip. The flipping space extends parallel to the length of the mounting bracket and passes through the flipping seat, so that both ends of the boom cylinder extend out of the flipping seat. That is, by controlling the movement of the welding device on the mounting bracket, a straight weld is achieved between the boom cylinder and the reinforcing plate. And by the linkage between the welding device and the flipping mechanism, the two ends of the boom cylinder are respectively circumferentially welded to the boom head and boom tail, thereby realizing the automatic welding of the boom assembly and achieving the purpose of ensuring product quality and improving welding efficiency. The aforementioned utility model is provided with a flipping mechanism for driving the boom cylinder to flip. The flipping mechanism is a U-shaped flipping seat for flipping and welding the boom. However, the boom is generally a square or other shape with sharp edges, and its surface does not have an arc surface that fits into the U-shaped seat. Therefore, it cannot be fully automated to fit and flip. In addition, during the continuous flipping process, the transmission structure at the sharp edges or inside the flipping seat is easily worn. Furthermore, the flipping is affected, which can also affect the thickness and state of the weld at the weld. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a welding equipment for the boom of an aerial work platform, including a base frame. Two sets of track frames are welded and installed on the top of the base frame. Four sets of sliders are slidably installed on both sides of the top of the track frames. An auxiliary tilting mechanism is installed between the sliders located between the track frames. A drive motor for driving is fixedly installed at one end of the auxiliary tilting mechanism. Two sets of pads are fixedly installed at the middle position on both sides of the base frame. A hydraulic cylinder is fixedly installed on the top of the pad. A welding component box is slidably installed on the top of the hydraulic cylinder.

[0005] The boom is flipped and welded using an auxiliary flipping mechanism to ensure that the outer circumference of the boom is completely welded.

[0006] As a further preferred technical solution of this utility model, welding blocks are welded and installed at both ends of the track frame, and a feeding rack is placed on the top of the welding blocks.

[0007] The inclined design of the loading rack improves the convenience of loading the boom cylinder.

[0008] As a further preferred technical solution of this utility model; a side plate is welded and installed on one side of the slider, a shock-absorbing spring is fixedly installed at the bottom of the side plate, and a pulley to assist the slider in sliding is installed at the bottom of the shock-absorbing spring. A sliding frame is welded and installed on the base frame at the bottom position of the pulley, and a U-shaped groove is opened on the top of the sliding frame to cooperate with the sliding of the pulley.

[0009] The pulleys slide within the U-shaped groove, providing auxiliary sliding support for the slider and reducing wear between the slider and the track frame. Similarly, the installation of shock-absorbing springs at the top of the pulleys dampens any swaying that occurs during sliding, ensuring the boom does not wobble and thus prevent welding position deviation.

[0010] As a further preferred technical solution of this utility model, the auxiliary flipping mechanism includes two sets of mounting plates fixedly installed with the slider and multiple sets of rotating rollers installed between the mounting plates by bearings, wherein the top of the rotating rollers and the top of the mounting plates are on the same plane.

[0011] The boom is placed on the rotating roller, and its stability is ensured by its own weight.

[0012] As a further preferred technical solution of this utility model, the drive motor is externally mounted to a set of mounting plates via a mounting box, and the output end of the drive motor is connected to a pulley set through the mounting box, which drives the two sets of rotating rollers to rotate.

[0013] When the boom needs to be welded around, it is generally not convenient to flip it due to its large size and weight. By starting the drive motor, two sets of rotating rollers are driven to rotate, so that the boom is subjected to the power transmission at the top of the rotating rollers, and the workers control the flipping.

[0014] As a further preferred technical solution of this utility model; a top plate is fixedly installed on the top of the hydraulic cylinder, and a connecting frame is fixedly installed on the top of the two sets of top plates. An electrically controlled sliding frame is slidably installed on the outside of the connecting frame. The welding component box is fixedly installed on the side of the electrically controlled sliding frame, and a welding head is fixedly installed on the bottom of one side of the welding component box.

[0015] The electric control system controls the sliding of the electric sliding frame to slide to the designated position for welding.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. When the boom needs to be circumferentially welded, it is generally not convenient to flip it due to its large size and weight. By starting the drive motor, two sets of rotating rollers are driven to rotate, so that the boom is subjected to the transmission force at the top of the rotating rollers. With the help of the workers, the boom can be flipped, which increases the convenience of flipping the boom, which is conducive to circumferential welding and reduces the welding difficulty.

[0019] 2. Moreover, the boom is generally a square structure with sharp edges. During the flipping process, only one side needs to be flipped. The electric sliding frame slides and welds the boom surface to avoid continuous flipping and reduce wear on the outer surface during the flipping process. Attached Figure Description

[0025] This specific embodiment is a welding equipment for the boom of an aerial work platform.

[0026] The aforementioned utility model is provided with a flipping mechanism for driving the boom cylinder to flip. The flipping mechanism is a U-shaped flipping seat for flipping and welding the boom. However, the boom is generally a square or other shape with sharp edges, and its surface does not have an arc surface that fits into the U-shaped seat. Therefore, it cannot be fully automated to fit and flip. In addition, during the continuous flipping process, the transmission structure at the sharp edges or inside the flipping seat is easily worn. Furthermore, the flipping is affected, which can also affect the thickness and state of the weld at the weld.

[0027] Its structural diagram is as follows Figures 1-4 As shown. A boom welding device for aerial work platforms includes a base frame 1, with two sets of track frames 2 welded to the top of the base frame 1. Welding blocks 26 are welded to both ends of the track frames 2, and a loading rack 25 is placed on top of the welding blocks 26. The inclined surface of the loading rack 25 improves the convenience of loading the boom. Four sets of sliders 21 are slidably installed on both sides of the top of the track frames 2. A side plate 22 is welded to one side of the slider 21, and a shock-absorbing spring 24 is fixedly installed at the bottom of the side plate 22. A pulley 23 is installed at the bottom of the shock-absorbing spring 24 to assist the slider 21 in sliding. A sliding frame 11 is welded to the base frame 1 at the bottom of the pulley 23, and a U-shaped groove 12 is opened on the top of the sliding frame 11 to cooperate with the sliding of the pulley 23. By sliding the pulley 23 inside the U-shaped groove 12, the slider 21 is assisted in sliding, providing support for the slider 21 and reducing wear between the slider 21 and the track frame 2. Similarly, the installation of the damping spring 24 on the top of the pulley 23 can dampen the shaking that occurs during sliding, ensuring that the boom does not shake during welding and thus does not shift the welding position.

[0028] An auxiliary tilting mechanism 3 is installed between the sliders 21 located between the track frames 2. The auxiliary tilting mechanism 3 includes two sets of mounting plates 31 fixedly mounted to the sliders 21 and multiple sets of rotating rollers 32 mounted between the mounting plates 31 via bearings. The tops of the rotating rollers 32 and the tops of the mounting plates 31 are on the same plane. The boom is placed on the rotating rollers 32, and its stability is ensured by its own weight. A drive motor 6 is fixedly mounted at one end of the auxiliary tilting mechanism 3. The drive motor 6 is welded to a set of mounting plates 31 via a mounting box 61. The output end of the drive motor 6 passes through the mounting box 61 and is connected to a pulley set 62, which drives the two sets of rotating rollers 32 to rotate. When the boom needs to be welded around the track, due to its large size and weight, it is generally inconvenient to tilt it. By starting the drive motor 6, the two sets of rotating rollers 32 are driven to rotate, so that the boom receives power at the top of the rotating rollers 32. This allows the operator to control and tilt the boom, increasing the ease of tilting and circumferential welding, and reducing the welding difficulty. Two sets of pads 13 are fixedly installed on both sides of the base frame 1 at the middle position, and a hydraulic cylinder 4 is fixedly installed on the top of the pads 13. A welding assembly box 5 is slidably installed on the top of the hydraulic cylinder 4. A top plate 41 is fixedly installed on the top of the two sets of top plates 41, and a connecting frame 42 is fixedly installed on the top of the two sets of top plates 41. An electrically controlled sliding frame 52 is slidably installed on the outside of the connecting frame 42. The welding assembly box 5 is fixedly installed on the side of the electrically controlled sliding frame 52, and a welding head 51 is fixedly installed on the bottom of one side of the welding assembly box 5. The electrically controlled sliding frame 52 is controlled to slide through the electrical control system, so that it slides to the designated position for welding. The boom is generally a square structure with edges. During the flipping process, only one side needs to be flipped. The electrically controlled sliding frame 52 slides to weld the surface of the boom, avoiding continuous flipping and reducing wear on the outer surface during the flipping process.

[0029] Example 1: The boom cylinder is pushed from the loading rack 25 to the auxiliary tilting mechanism 3 by the inclined surface of the loading rack 25. The boom cylinder is pushed so that the slider 21 slides on the track frame 2, and the pulley 23 assists in supporting the slider 21. The position of the boom cylinder to be welded is adjusted. After adjustment, the welding assembly box 5 can be started, and the welding head 51 welds the weld seam.

[0030] Example 2: When the boom needs to be welded around, it is generally not convenient to flip it due to its large size and weight. By starting the drive motor 6, the two sets of rotating rollers 32 are driven to rotate, so that the boom is subjected to the transmission force at the top of the rotating rollers 32, and the workers control the flipping.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
