Power line collecting and releasing device for building machine

Abstract

The invention discloses a power line collecting and releasing device for a building machine. The power line collecting and releasing device comprises a box body. A rotating rod is arranged in the boxbody. The rotating rod is rotationally connected with the box body through first bearings. A first through hole is formed in the left side of the upper surface of the box body, and a second through hole is formed in the lower surface of the box body. The outer wall of the rotating rod is movably sleeved with a power line which is attached to the first through hole. The power line is attached to the second through hole. According to the power line collecting and releasing device for the building machine, when line collecting and releasing work is conducted, due to cooperation of the box body, aspring, the rotating rod and the bearings, the power line is stored in the box body when work is not needed, and the service life of the power line can be prolonged; and due to cooperation among a first screw rod, a rotary disc, the power line, the rotating rod, the spring and the first bearings, the power line can be rapidly collected and released in order, and the phenomenon that the power lineis disordered cannot happen.

Description

technical field [0001] The invention relates to the technical field of retractable power cords for construction machinery, in particular to a retractable device for power cords for construction machinery. Background technique [0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. Stress machinery, decoration machinery, high-altitude operation machinery and other machinery, but each kind of mechanical equipment is inseparable from the power supply when it is working, and the power cord connected to the power supply is usually wound together after use. On the ground or hanging on the wall, there are often employees who accidentally step on or kick the power cord, which reduces the service life of the power cord. In severe cases, there is a risk of leakage and short circuit, and the process of taking up the cord requires a certain amount of time. Time, when the power cord is used for th...

[0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. Stress machinery, decoration machinery, high-altitude operation machinery and other machinery, but each kind of mechanical equipment is inseparable from the power supply when it is working, and the power cord connected to the power supply is usually wound together after use. On the ground or hanging on the wall, there are often employees who accidentally step on or kick the power cord, which reduces the service life of the power cord. Time, when using the power cord for the first time, the power cord may be disorganized, and it will take a certain amount of time to thread the wire before it can be used again, making the overall work efficiency low
