Lifting device for electric construction

Abstract

The invention discloses a lifting device for electric construction. The lifting device comprises an overload protecting device capable of automatically giving an alarm, an illuminating lamp, a liftingcylinder, a support rod, a base plate, a protective cover, wheels, trundles, trundle fixed plates, a direction control rod and a ventilation pipe; the lifting cylinder is welded at the left end of the upper surface of the overload protecting device capable of automatically giving an alarm; the illuminating lamp is glued to the upper end of the lifting cylinder; and the ventilation pipe is embedded in the right surface of the overload protecting device capable of automatically giving an alarm. Through arrangement of the overload protecting device capable of automatically giving an alarm, afterequipment circuits are aged, the bearing capacity on current and voltage disorder change is reduced, and the overload protecting device can protect the circuit safety to protect the equipment safety;and after the overload protecting device cuts off the equipment circuits, the alarm lamp can be timely brightened, so that workers timely know the equipment working state, the equipment safety is protected, and the workers are convenient for subsequent construction.

Description

technical field [0001] The invention relates to a lifting device for electric power construction, which belongs to the field of lifting devices. Background technique [0002] As the name suggests, the lifting device is a device that can rise and fall. In the process of electric power construction, it is conducive to the rapid progress of construction tasks and is convenient for people to work. [0003] However, due to the long-term use of the equipment in the prior art, after the internal circuit is aging, circuit failures are prone to occur, and the instantaneous value of the current or voltage may increase instantaneously, resulting in a short circuit of the equipment. Automatic alarm, which affects the construction progress and shortens the service life of the equipment. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a lifting device for electric power construction to solve the problems ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a lifting device for electric power construction to solve the problems of the equipment in the prior art. Due to long-term use, after the internal circuit is aging, circuit faults are prone to occur, and current or voltage fluctuations may occur. The instantaneous value may increase instantaneously, causing a short circuit of the equipment. In severe cases, the equipment may be burned out, and the equipment cannot automatically alarm when the equipment fails, which affects the construction progress and shortens the service life of the equipment.
