Abstract
Description
Technical Field
[0001] The present application relates to the technical field of lifting equipment, and in particular to a small lifting device used in a welding smoke collection shed. Background Art
[0002] Welding is a process that uses electric energy to heat the metal to make it partially liquid or near liquid, so that it can be combined to form a strong, non-detachable joint. Welding fume is the main pollutant. It is formed by oxidation and condensation of steam generated by metal and non-metallic substances under overheating conditions. Therefore, the generated welding fume needs to be centralized and then discharged outside the construction site.
[0003] In the prior art, in order to centralize the generated welding smoke, a relatively low welding smoke collection shed is usually set up inside the factory area, and all welding operations are concentrated under the welding smoke collection shed. By lowering the height of the top wall of the welding smoke collection shed and adding an exhaust mechanism to discharge the welding smoke generated in the welding smoke collection shed in time, it is prevented that the welding smoke stays in the factory for a long time or spreads to affect the health of other construction workers. Gantry cranes are generally used inside the factory for lifting, transporting, and installing materials. For some small and medium-sized weldments, the use of gantry cranes is firstly costly. Secondly, due to the interference between the top wall of the welding smoke collection shed and the movement trajectory of the gantry crane's hoisting rope, the gantry cranes inside the factory cannot be used for lifting operations of weldments in the welding smoke collection shed. Manual transportation not only seriously increases the labor intensity of the staff, but also poses a great safety hazard. Therefore, it is urgent to design a new lifting equipment that can be adapted to the welding smoke collection shed to solve the above-mentioned problems. Utility Model Content
