Description

Technical Field

[0001] The utility model belongs to the technical field of threading devices, in particular to an electromechanical lead threading device. Background Art

[0002] At present, the construction of electrical pipe threading in domestic electromechanical installation and distribution projects is generally to blow compressed air into the laid pipes after the reserved and embedded stage is completed to remove residual dust and moisture; or tie a dry cloth on the steel wire, stretch it into the pipe and drag it back and forth to clean the pipe, and then use the steel wire as a lead, gradually feed it from one end of the pipe until the other end leaks out. The purpose is to hang the wire on one end of the steel wire during threading, and pull out the steel wire at the other end of the wire pipe to complete the threading. However, if there are many pipe elbows or foreign objects in the pipe during the threading process, it is necessary to re-thread a steel wire at the other end or re-clean the pipe. The threading efficiency is very low and the labor intensity is high; and when the pipeline is long, a large amount of steel wire needs to be wasted, which is not in line with the principles of energy conservation and environmental protection.

[0003] In view of the above situation, this project studies and experiments a new type of electromechanical lead threading technology, which is made of small pressure pumps (air pumps), hoses, discarded fire extinguishers, plastic ropes, rubber and other materials. The air pressure in the fire extinguisher is increased and stored by the air pump, and the rubber head is fixed to the front end of the lead (plastic rope). The lead is inserted into the pipeline through the air pressure in the air pump, and the dust and moisture remaining in the pipeline are blown out at the same time. It is in place at one time. Without wasting the lead, the threading efficiency is improved, the workload of workers is reduced, and the labor force is liberated. In today's social environment where the construction industry advocates green construction and the energy-saving and environmental protection policies of the whole society, it has great significance.
