Abstract

The utility model provides an electronic control system of an electric hanging basket. The electronic control system of the electric hanging basket comprises a motor work unit and a motor control unit. The motor work unit comprises two motors, three-phase supply input units, a leakage protector, thermal relays and rectifier modules. The three-phase power supply input unit, the leakage protector, the thermal relays and the rectifier modules control the motors to operate and are in electric connection with each other in sequence. The motor control unit comprises a transformer. A primary loop circuit of the transformer is connected with a single-phase power supply. A fuse and a scram button are connected with a secondary loop circuit of the transformer in series. The transformer is further provided with a change-over switch and two wire control buttons. Contactors are in electric connection with the change-over switch and the wire control buttons. The change-over switch controls the two motors to operate alone to adjust balance. A contactor control unit controls the hanging basket to rise and fall in the secondary loop circuit of the transformer. The electronic control system of the electric hanging basket has the advantages of being reliable and safe in controlling.

Description

A kind of electric-control system of driven hanging basket

Technical field

The utility model relates to the construction implement technical field, relates in particular to a kind of electric-control system of driven hanging basket.

Background technology

Hanging basket is the vehicle for construction of building engineering aloft work, and the high-altitude hanging basket is easy for installation, electric up-down, and operating efficiency is high, and floor area is little, disposes working rope and safety rope, and is safe and reliable, is fit to various complicated construction environment.Such as skin construction operation and maintenance decorative operation.At the construction operation of big city skyscraper, building compact district, the maintenance of residential quarters is whitewashed, and more can show its economy, convenience, safety, efficient preceence.Hanging basket comprises suspension platform, gig and electric-control system, by the electric control system controls gig, thereby control suspension platform rising, descend and stop the action.

In the prior art, owing to frequent starting, the switch of motor burnt easily when motor used, and safety, the reliability that the electrical control of electric-control system connects is still waiting to improve, and prevents potential safety hazard.

The utility model content

For the problems referred to above, problem to be solved in the utility model provides a kind of electric-control system of driven hanging basket.

The technical solution of the utility model is as follows:
