Description

Technical Field

[0001] This utility model relates to the field of welding protection technology, specifically to an electric welding machine for building construction with a fume treatment structure. Background Technology

[0002] The fumes generated during welding can harm the health of welders. Currently, fixed welding stations collect and treat welding fumes to ensure a good welding environment. However, during construction, welding points are often variable and located in open-air environments, making fixed welding fume treatment equipment unsuitable. Passive protection methods such as face masks offer limited protection, and the welding space is often restricted in various ways during construction, making it difficult for current fixed fume collection and treatment equipment to adapt to actual site conditions.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a construction welding machine with a fume treatment structure that is flexible and convenient to use, has a good effect on welding fume treatment, and is flexible in use.

A screw is threadedly connected to the inner side of the support cylinder. The bottom end of the screw is fixedly connected to the center of the top of the rectangular base plate. Each of the four corners of the bottom of the base plate has a long strip-shaped square groove from the outside to the inside. The inner side of each square groove is rotatably connected to one side of a counterweight plate through a shaft.

[0010] The drive unit of the intake fan is connected to the output end of the cable, and the input end of the cable is connected to the power supply unit of the welding machine body;

[0011] The outer wall of the fixed box is rotatably connected to a storage tray, and the cable is wound around the storage tray.

[0012] A fixing block is fixedly connected to the outer wall of the fixing box. Two arc-shaped clamps are symmetrically fixedly connected to the outer wall of the fixing block away from the fixing box. The inner sides of the two clamps slide in cooperation with the outer wall of the support cylinder.

[0017] A rubber sleeve is fitted at the bottom end of the support cylinder, and the inner wall of the bottom side of the rubber sleeve is in contact with the outer wall of the screw.

[0018] In actual use, after bringing the welding body close to the welding point, lift the fixing box upwards using the handle. When the screw is inside the clamping plate, move the fixing box outwards. The height of the fixing box can be adjusted by rotating the screw according to the welding position. The counterweight plate can be rotated outwards and placed on the ground to ensure the stability of the process. The universal suction pipe can be adjusted so that the gas collection hood corresponds to the welding position. After the preparation is complete, the welding machine can be started. When the welding machine is powered on, the power supply component powers the cable, thereby driving the suction fan to rotate. The fumes are sucked into the fixing box through the gas collection hood and are discharged from the exhaust port after being filtered and purified by the filter bag and filter cartridge.
