Description

Technical Field

[0001] The utility model relates to a welding machine head hanging column lifting machine. Background Art

[0002] Plastic fuel tanks, i.e. fuel storage devices, have high requirements for corrosion resistance. They should be sealed at a gauge pressure of at least 0.03 MPa at double working pressure. The generated overpressure must be reduced by itself through holes or safety valves. When driving on curves, inclined roads or impacts, the fuel should not flow out of the filling sealing cap or pressure equalization device. The fuel tank must be installed away from the engine to avoid ignition of the fuel in the event of a traffic accident. A welding machine is usually used to weld the welding line on the plastic fuel tank.

[0003] With the increase in the types of plastic fuel tanks, the number of welding lines has also increased. In order to better weld the welding lines on the plastic fuel tanks, the number of welding machines needs to be increased accordingly. During the production process, the welding machine head suspension column needs to be installed. Since the welding machine head suspension column is heavy, it needs to rely on multiple people to lift and install it. This installation method not only causes labor waste, but also easily leads to safety accidents if someone accidentally drops it during the handling process. Therefore, how to better reduce labor and reduce the occurrence of safety accidents is an important issue that needs to be solved in the design of the welding machine head suspension column lifting machine.
