Abstract

The utility model discloses a movable grounding protection device for electric welding equipment, which is suitable for electric welding equipment of various types movably used both indoors and outdoors, ensuring the effective grounding of the housing of the electric welding equipment and thereby ensuring the use safety of the electric welding equipment. The device comprises wires, a wire winding disc, and a grounding rod, wherein the wires are winded around the wire winding disc with one end provided with a connection terminal and the other end connected with the grounding rod. The wire winding disc and the grounding rod facilitate the grounding connection of the electric welding equipment, and the grounding rod can be conveniently smashed into ground in situ, thereby achieving reliable grounding of the electric welding equipment. The device is simple in structure and provides reliable connections so that the safe grounding of the electric welding equipment in use is ensured. By using the grounding protection device, the operators are provided with simple, convenient and standard grounding operations, the safety of personnel and equipment is ensured, and unnecessary equipment damages and personal injuries are reduced, thereby helping to reduce production cost.

Description

The packaged type earth protective device of electric welding equipment
Technical field
The utility model belongs to the earth protective device of electric welding equipment; The packaged type earth protective device of electric welding equipment particularly; Be applicable to that indoor and outdoor moves the electric welding equipment of the various models of use, guarantee the shell effective grounding of its electric welding equipment, ensure the safe in utilization of electric welding equipment.
Background technology
Electric welding equipment is called electric welding machine usually, and clear and definite earthing of casing requirement is all arranged in the use of all kinds of electric welding machines, place's grounding electrode all is set specially, normally one piece of bolt on the shell of every electric welding machine.That electric welding machine in use receives is aging, the network voltage sudden change, the original paper failure and other reasons is short-circuited even during scaling loss, can cause the electric welding machine outer casing electrification, causes workmen's injury.Only electric welding machine earthing of casing resistance has been made regulation in the national standard, all do not stipulated for the earthing of casing lead and the device of electric welding machine.The earthing of casing of electric welding machine is various informative, and the common copper cash of the usefulness that has connects, also have with the aluminium stranded conductor crimping perhaps with electrical network earth connection hybrid junction; Above-mentioned earthing mode is both lack of standardization also dangerous; Reliability difference is big, is unfavorable for the protection to the workmen, is easy to cause device damage and personnel injury.
Summary of the invention
The purpose of the utility model is the defective to prior art, and the packaged type earth protective device of electric welding equipment is provided, and makes things convenient for the ground connection operation of electric welding equipment, guarantees that ground connection is reliable, the safety of protection operating personnel and equipment.
The utility model is achieved in that the packaged type earth protective device of electric welding equipment comprises lead, lead dish and earth rod, and lead is wrapped on the lead dish, and an end is provided with binding post, and the other end is connected with earth rod.Lead dish and earth rod have been arranged, made things convenient for the ground connection of electric welding equipment to connect, can seek the ground of conveniently pounding on the spot, made electric welding equipment realize reliable ground connection into earth rod.
Compared with prior art the beneficial effect of the utility model is: the utility model is simple in structure, connection is reliable, can guarantee employed electric welding equipment safety ground.Through the use of this earth protective device, can ground connection operation simple and effective, standard, the safety of support personnel and equipment be provided for operating personnel.Reduce unnecessary equipment damage and personal injury, help reducing production costs, also can be used as other earthing Protection of Electric Apparatus device simultaneously, have obvious social.
