Welding machine mobile protection box

Abstract

The invention discloses a mobile protection box of an electric welding machine. The mobile protection box of the electric welding machine includes a box body, wherein the electric welding machine is arranged in the box body, and a plurality of screw bars are vertically connected with the inner wall of the box body. A nut is arranged on the upper screw of the screw rod, and one end, far away from the side wall of the box body, of the nut is connected with a connecting rod to abut against the outer wall of the electric welding machine. The nut is a butterfly nut, and the two butterfly wings of the butterfly nut are arranged toward the direction of the electric welding machine. The connecting rod is parallel to the screw rod, and the length of the connecting rod is not less than the length ofthe screw rod. The safety protection, movement and warning performance of the electric welding machine is improved; the service life of the electric welding machine is improved; a two-time unloaded step-down protector is added to improve voltage safety of the electric welding machine during unloading; the cost of power consumption is reduced; the risks such as electric shock and fire are reduced;the safety and energy saving performance of the electric welding machine are greatly improved; and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of protection devices for electric welding machines. More specifically, the present invention relates to a mobile protection box for an electric welding machine. Background technique [0002] Electric welding machines are widely used in engineering construction, and the construction site has higher and higher requirements for safe and fast use of electric welding machines. The following problems exist in the existing electric welding machines in the process of engineering use: First, the working principle of electric welding machines is to use instantaneous strong current , Convert electrical energy into heat energy to melt the welding material to achieve the purpose of welding. The welding machine generates a strong current during operation, which can easily affect the temporary power voltage balance of the construction site, cause damage to the welding machine itself and other electrical equipment, and easily cause...

AI Technical Summary

Problems solved by technology

The welding machine produces strong current during operation, which can easily affect the temporary power voltage balance of the construction site, cause damage to the welding machine itself and other electrical equipment, and easily cause fire, electric shock accidents and other safety hazards

Second, in the process of engineering construction, there are many tasks in electric welding and welding operations.

Before each operation, it is necessary to connect the power input cable and the operation output cable. Not only is the work complicated, which affects work efficiency, but also often causes electric shock safety hazards due to human factors such as workers' carelessness and random wiring operations.

The third is that the electric welding machine needs to move frequently due to the welding operation, and the mobile wheel that comes with the electric welding machine is simple to manufacture and is easily damaged, and the mobile performance is poor, which brings great inconvenience to the user, and it does not have a braking function when working on a slope, which is prone to accidents. slippery risk

Fourth, the engineering construction environment is complex, especially in tunnels and mines where the construction space is narrow, the lighting is insufficient, and there are many construction equipment. The electric welding machine is often damaged by collision and rolling by other large equipment due to improper protection, and there are great safety hazards. Invisibly increase the cost of repairing and replacing welding machines
