Description

Technical Field

[0001] This utility model relates to the field of steel box girder technology, and in particular to a welding equipment for the flange of a steel box girder. Background Technology

[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans. Because their shape resembles a box, they are called steel box girders. During the production of steel box girders, the flange plates need to be welded to both sides of the web plate.

[0003] A search revealed a Chinese patent (application number "202310422184.X") that discloses "a welding device for steel box girder wing plates." This welding device includes a base box, with a lifting seat movably mounted on the upper surface of the base box. A left robotic arm and a right robotic arm are rotatably mounted on one side of the lifting seat. A welding torch is mounted at the end of the left robotic arm, and a scraping block is mounted at the end of the right robotic arm. A pressing component is mounted on the lifting seat, and multiple drive wheels are rotatably mounted at the bottom of the base box. However, this welding device cannot adsorb and purify the harmful gases generated during welding, allowing these gases to disperse into the external environment, resulting in poor environmental performance. Utility Model Content

[0004] This utility model provides a welding device for steel box girder flanges, which solves the problem that the welding device proposed in the prior art cannot adsorb and purify the harmful gases generated during welding when splicing steel box girder flanges, resulting in the harmful gases drifting into the external environment and having poor environmental performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding device for steel box girder flanges includes a base plate. A mounting mechanism is provided on the top of the base plate. The mounting mechanism includes a support plate bolted to the outer wall of the top of the base plate and a limiting plate bolted to the outer wall of the top of the base plate. A lifting assembly is provided on the base plate. The lifting assembly includes a lifting cylinder, a lifting plate bolted to the bottom end of the piston rod of the lifting cylinder, and a mounting plate bolted to the bottom outer wall of the lifting plate. An extension assembly is provided on one side of the limiting plate. The extension assembly includes an extension cylinder bolted to the outer wall of one side of the mounting plate, a connecting plate bolted to one end of the piston rod of the extension cylinder, and a welding torch. A purification mechanism is provided on the top of the base plate. The purification mechanism includes a mounting box bolted to the outer wall of the top of the base plate, several activated carbon filters slidably fitted inside the mounting box, and an exhaust fan bolted to the outer wall of one side of the mounting box.

[0007] Preferably, the four corners of the bottom of the base plate are each bolted with a universal wheel with brake, and two handles are welded to the outer wall of the top end of the base plate.

[0008] Preferably, two stabilizing plates are bolted to one side of the outer wall of the support plate and the limiting plate, and four stabilizing plates are bolted to the top outer wall of the bottom plate. A top plate is bolted to the top outer wall of the support plate, and the bottom of the top plate is bolted to the top outer wall of the limiting plate.

[0009] Preferably, the lifting cylinder is bolted to the top outer wall of the top plate, the lifting plate and the mounting plate abut against the outer wall of one side of the limiting plate, and two triangular plates are bolted to the bottom outer wall of the lifting plate, and the two triangular plates are bolted to the outer wall of one side of the mounting plate.

[0010] Preferably, the outer wall of the limiting plate has a slide rail, and one end of the extension cylinder is slidably sleeved in the slide rail. Two limiting rods are bolted to one side of the outer wall of the connecting plate, and the two limiting rods pass through and are slidably sleeved on the outer wall of the mounting plate. The outer walls of the limiting plate on both sides of the slide rail have channels, and the two limiting rods are slidably sleeved in the two channels. A damping hinge is bolted to one side of the outer wall of the connecting plate, and a connecting block is bolted to one end of the outer wall of the damping hinge. The welding torch is bolted to the outer wall of the connecting block.

[0011] The above scheme uses the movement of the piston rod of the lifting cylinder to move the extension cylinder and the welding torch, thereby adjusting the height of the welding torch. At the same time, the movement of the piston rod of the extension cylinder moves the welding torch, thereby adjusting the horizontal position of the welding torch. The welding torch can be manually flipped to adjust its angle.

[0012] Preferably, a ventilation pipe is fixedly installed on the upper inner wall of one side of the mounting box, and the ventilation pipe passes through and is embedded in the outer wall of the limiting plate. A flow guide is bolted to the lower outer wall of one side of the limiting plate, and the flow guide is fixed to the outer wall of one end of the ventilation pipe. Limiting blocks are provided on both sides of several activated carbon filters, and several limiting blocks are welded to the bottom inner wall of the mounting box. A box cover is hinged to one outer wall of the mounting box.

[0013] The above solution involves using an exhaust fan to draw the air near the welding torch, mixed with harmful gases generated during welding, into a flow guide hood. The harmful gases are then transported to the installation box via a ventilation duct, where multiple activated carbon filters adsorb and purify the harmful gases.

[0014] The beneficial effects of this utility model are as follows:

[0015] The exhaust fan operates, drawing the air near the welding torch, along with the harmful gases generated during welding, into the exhaust hood. The harmful gases are then transported to the installation box via the ventilation duct. Multiple activated carbon filters inside the installation box adsorb and purify the harmful gases, preventing them from drifting into the external environment and being inhaled by workers, thus improving environmental friendliness.
