Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a mobile steel structure surface welding device. Background Technology

[0002] In the field of steel structure processing, from component manufacturing to overall frame construction, as well as the construction process, whether it is a towering skyscraper or a large-scale industrial plant, welding operations are frequently and extensively required on the surface of the steel structure.

[0003] Traditional welding equipment is mostly fixed in location, which greatly reduces its flexibility and makes it difficult to quickly move to different work sites. Because the welding equipment cannot be moved flexibly, workers have to repeatedly adjust the position of the steel structure or rearrange the welding equipment. Each adjustment not only consumes a lot of time but also requires a lot of manpower, which seriously slows down the welding progress and leads to a significant reduction in overall welding efficiency. At the same time, some welding equipment with movable functions has inconvenient adjustment of the position and angle of the welding gun. When facing welding tasks of complex structures, it is difficult to accurately operate the weld seam, the welding quality cannot be guaranteed, the use effect is poor, and it cannot meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a convenient and mobile steel structure surface welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile steel structure surface welding device, comprising a base plate, a support frame, an adjustment component, and a welding gun, wherein the support frame is fixedly installed on the top of the base plate, the adjustment component is disposed on the top of the support frame, and the welding gun is disposed on the surface of the adjustment component.

[0006] The adjustment assembly consists of a multi-stage electric push rod, a mounting bracket, a threaded rod, a slide rod, a first motor, a disc, an annular tube, a first gear, a second motor, and a second gear. The multi-stage electric push rod is fixedly installed inside the support bracket. The mounting bracket is fixedly installed at the moving end of the multi-stage electric push rod. The threaded rod is rotatably installed inside the mounting bracket. The slide rod is fixedly installed inside the mounting bracket. The first motor is fixedly installed on the side of the mounting bracket. The disc is threadedly installed on the surface of the threaded rod. The annular tube is rotatably installed on the side of the disc. The first gear is fixedly installed on the surface of the annular tube. The second motor is fixedly installed on the side of the disc. The second gear is fixedly installed on the output shaft of the second motor.

[0007] Preferably, a handrail is fixedly installed on the side of the base plate, and a lockable roller is installed on the bottom of the base plate. The handrail provides a point of force for the user to hold and move the device. The lockable roller installed at the bottom can reduce the resistance during movement, allowing the device to easily change position. When the device reaches the designated position, the roller is locked to restrict its rolling and prevent the device from shifting.

[0008] Preferably, the number of support frames and multi-stage electric push rods is one per group, with two groups symmetrically arranged on the top of the base plate. The two groups of support frames and multi-stage electric push rods are symmetrically distributed on the top of the base plate. When the height of the welding gun needs to be adjusted, the two multi-stage electric push rods start synchronously, using electrical energy to convert into mechanical energy to push the mounting frame to rise and fall. Due to the symmetrical layout, the mounting frame can maintain balanced force, avoid tilting, and adjust the welding gun to the required working height.

[0009] Preferably, the output shaft of the first motor and the threaded rod are fixedly connected. After the first motor is powered on, electrical energy is converted into mechanical energy, which drives the output shaft to start rotating. Since the output shaft is fixedly connected to the threaded rod, it can drive the threaded rod to rotate.

[0010] Preferably, the disc is slidably mounted on the surface of the slide rod. When the disc moves under the action of the driving force, the slide rod, by virtue of its own straight shape, restricts the disc to move only along the axial direction of the slide rod, which can prevent the disc from deviating or shaking during the movement and ensure the smooth movement of the disc.

[0011] Preferably, the first gear and the second gear mesh. After the second motor is started, the output shaft of the second motor drives the second gear to rotate. Since the first gear and the second gear mesh with each other, the rotation of the second gear will transmit torque to the first gear through the interaction force between the teeth. The first gear is fixedly connected to the annular tube, so it can drive the annular tube to make circular motion around its axis.

[0012] Preferably, the welding gun is mounted on the surface of the annular tube, and the welding gun can be rotated by the annular tube, so that the angle of the welding gun can be adjusted.

[0013] Compared with the prior art, the beneficial effects of this utility model are: after the easily movable steel structure surface welding device is moved to the designated position by the handrail, the roller is locked to prevent the device from shifting; the second motor is started to adjust the angle of the welding gun; the multi-stage electric push rod is started to make the welding gun fit against the steel structure surface; and the first motor is started to drive the welding gun to move horizontally, so as to weld the steel structure surface. The effect of use is good. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a conveniently movable steel structure surface welding device, including a base plate 1, a support frame 2, an adjustment component 3, and a welding gun 4. The support frame 2 is fixedly installed on the top of the base plate 1, and a handrail is fixedly installed on the side of the base plate 1. Lockable rollers are installed at the bottom of the base plate 1. The handrails provide a point of force for the user to hold and move the device. The lockable rollers at the bottom can reduce the resistance during movement, allowing the device to easily change position. When the device reaches the designated position, the rollers are locked to restrict their rolling and prevent displacement. The adjustment component 3 is located on the top of the support frame 2, and the welding gun 4 is located on the surface of the adjustment component 3.

[0021] The adjustment assembly 3 consists of a multi-stage electric push rod 301, a mounting bracket 302, a threaded rod 303, a sliding rod 304, a first motor 305, a disc 306, an annular tube 307, a first gear 308, a second motor 309, and a second gear 310. The multi-stage electric push rod 301 is fixedly installed inside the support frame 2. Both the support frame 2 and the multi-stage electric push rod 301 are arranged in groups of one, with two groups symmetrically positioned on the top of the base plate 1. When the height of the welding gun 4 needs to be adjusted, the two multi-stage electric push rods 301 are activated synchronously, converting electrical energy into mechanical energy to push... The mounting bracket 302 is raised and lowered. Due to its symmetrical layout, it maintains balanced force distribution, preventing tilting and allowing adjustment of the welding gun 4 to the required working height. The mounting bracket 302 is fixedly mounted on the moving end of the multi-stage electric push rod 301. The threaded rod 303 is rotatably mounted inside the mounting bracket 302. The sliding rod 304 is fixedly mounted inside the mounting bracket 302. The first motor 305 is fixedly mounted on the side of the mounting bracket 302. The output shaft of the first motor 305 is fixedly connected to the threaded rod 303. After the first motor 305 is powered on, electrical energy is converted into mechanical energy, driving the output shaft to rotate. Because the output shaft is fixedly connected to the threaded rod 303, it can drive... When the threaded rod 303 rotates, the disc 306 is threaded onto the surface of the threaded rod 303 and slidably mounted on the surface of the slide rod 304. When the disc 306 moves under the action of driving force, the slide rod 304, by virtue of its linear shape, restricts the disc 306 to move only along the axial direction of the slide rod 304, which can prevent the disc 306 from deviating or shaking during movement, ensuring smooth movement of the disc 306. The annular tube 307 is rotatably mounted on the side of the disc 306, and the welding gun 4 is mounted on the surface of the annular tube 307. The welding gun 4 can be rotated through the annular tube 307, and its angle can be adjusted. The first gear... The first gear 308 is fixedly installed on the surface of the annular tube 307, the second motor 309 is fixedly installed on the side of the disc 306, and the second gear 310 is fixedly installed on the output shaft of the second motor 309. The first gear 308 and the second gear 310 mesh. After the second motor 309 is started, the output shaft of the second motor 309 drives the second gear 310 to rotate. Since the first gear 308 and the second gear 310 mesh with each other, the rotation of the second gear 310 will transmit torque to the first gear 308 through the interaction force between the teeth. The first gear 308 is fixedly connected to the annular tube 307, so it can drive the annular tube 307 to make circular motion around its axis.

[0022] In use, after moving the device to the designated position via the handrail, the rollers are locked to prevent displacement. The second motor 309 is then activated, and under the action of the first gear 308 and the second gear 310, the annular tube 307 can rotate around its axis, which can drive the welding gun 4 to rotate and adjust the angle of the welding gun 4. The multi-stage electric push rod 301 is activated to drive the welding gun 4 to rise, allowing the welding gun 4 to fit against the surface of the steel structure. The first motor 305 is activated to drive the threaded rod 303 to rotate, and under the guidance of the slide rod 304, the disc 306 can move horizontally, thereby driving the welding gun 4 to move horizontally, allowing welding to be performed on the surface of the steel structure.
