In workshops where welding is concentrated, special welding fume treatment devices need to be installed to purify the fumes generated by welding before discharge. In large-scale equipment production workshops, due to the large number of welding positions for products, the welding position needs to be changed many times during the processing process. Traditional welding fume treatment equipment is small, and each time the welding position is changed, the welding fume treatment equipment needs to be moved synchronously, which increases the complexity of welding and reduces the efficiency of welding.

[0025] The welding smoke treatment device of this embodiment includes a traveling mechanism, a smoke hood 2 and a lifting and positioning mechanism 3. The traveling mechanism includes a traveling frame 11 and a traveling driving member. The traveling frame 11 is driven by the traveling driving member to travel in a preset direction, and a welding smoke dust collector 4 is arranged on the traveling frame 11; the lifting and positioning mechanism 3 is arranged on the traveling frame 11, and the action end of the lifting and positioning mechanism 3 is connected with the smoke hood 2 and drives the smoke hood 2 to move up and down between the working position and the standby position. A lifting curtain 21 is arranged on the side of the smoke hood 2, and the space defined by each lifting curtain 21 below the smoke hood 2 forms a welding processing space, and the welding smoke dust collector 4 is connected with the welding processing space, and a lifting connecting rod 23 is also hinged at the corresponding lifting curtain 21 on the smoke hood 2, and the lifting connecting rod 23 is connected to the action end of the lifting and positioning mechanism 3 and the lifting curtain 21, and when the smoke hood 2 is in the working position, the lifting curtain 21 is in the extended position, and when the smoke hood 2 is in the standby position, the lifting curtain 21 is in the folded avoidance position.

[0026] Specifically, the walking mechanism includes a walking frame 11 and a walking drive member. The walking frame 11 is provided with a walking wheel 12. The walking frame 11 is supported by the walking wheel 12. The walking drive member is arranged on the walking frame 11. The power output end of the walking drive member is in transmission cooperation with the walking wheel 12. The walking drive member drives the walking frame 11 to move along a preset direction by driving the walking wheel 12 to rotate. The walking drive member is a servo motor, a forward and reverse motor or other rotating motor. A welding smoke dust collector 4 is arranged on the walking frame 11. The welding smoke dust collector 4 is a prior art product. The structure of the welding smoke dust collector 4 is not described in this application document.

[0027] The lifting and positioning mechanism 3 is arranged on the traveling frame 11, and the action end of the lifting and positioning mechanism 3 is connected with the smoke hood 2, and the lifting and positioning mechanism 3 can drive the smoke hood 2 to be lifted and adjusted. Driven by the lifting and positioning mechanism 3, the smoke hood 2 moves between the working position and the standby position. A lifting curtain 21 is arranged on the side of the smoke hood 2, and the space defined by each lifting curtain 21 below the smoke hood 2 forms a welding processing space, and the welding smoke dust collector 4 is connected with the welding processing space.

When the lifting and positioning adjustment mechanism 3 drives the smoke hood 2 to be lifted to the standby position, it also drives the lifting curtain 21 to be in the folded avoidance position. At this time, the lifting curtain 21 is in the folded state. When the walking mechanism is walking, the lifting curtain 21 is in the folded avoidance position to avoid touching the automatic welding robot 6.

[0029] The welding smoke treatment device of this embodiment is suitable for welding processing, and is particularly suitable for the scene of automatic welding processing of large equipment using an automatic welding robot 6. According to the welding processing position, the travel drive can drive the travel frame 11 to travel and shift.

After the travel frame 11 moves to the position where the smoke hood 2 is above the welding processing position, the lifting and positioning mechanism 3 drives the smoke hood 2 to descend to the working position. While the lifting and positioning mechanism 3 drives the smoke hood 2 to move to the working position, it also drives the lifting connecting rod 23 to flip, so that the lifting curtain 21 changes from the folding avoidance position to the extended position. At this time, the welding processing position is in the welding processing space formed by the lifting curtain 21 and the smoke hood 2. The welding smoke generated by the welding process is sucked away by the welding smoke dust collector 4 and discharged after purification.

When the smoke hood 2 moves in the preset direction with the traveling frame 11, only the two lifting curtains 21 are driven by the lifting and positioning mechanism 3 to avoid the automatic welding robot 6. The space below the smoke hood 2 defined by the two lifting curtains 21 and the two transparent observation curtains is a welding processing space. During the welding process, workers can observe the specific conditions of the welding process from the outside of the smoke hood 2 through the transparent observation curtains.

[0039] Under the action of the gravity of the lifting curtain 21 itself, the lifting connecting rod 23 rotates around the hinge with the smoke and dust hood 2 in the direction close to the corresponding lifting curtain 21, which will cause the lifting curtain 21 to descend, and the lifting curtain 21 moves to the extended position. The lifting connecting rod 23 rotates around the hinge with the smoke and dust hood 2 in the direction of the lifting shaft 31, which will drive the lifting curtain 21 to rise, and the lifting curtain 21 moves to the folded avoidance position.
