Abstract

The invention discloses a method for improving balance of power-driven hanging basket working platform and an electrical system. The method comprise: comparing the given signal with the current detection and position detection signals fed back during running of left and right switched reluctance motors by a first reluctance motor controller and a second reluctance motor controller; sending the exact control information combined by the first reluctance motor controller and the second reluctance motor controller to the left and right switched reluctance motors to eliminate difference between the two motors so as to realize synchronization of the two motors. The electrical system comprises left and right hanging basket hoisting machines with the same structures, the first reluctance motor controller, the second reluctance motor controller, an ascending switch BTA, a descending switch FTA and a stop switch QA. The invention is characterized by exact synchronization, stable running, accurate control and high safety and reliability.

Description

technical field

[0001] The invention is applied in the field of construction machinery and motor control, and can accurately control the rotation speeds of the left and right hoist motors of the existing electric hanging baskets for high-altitude operations, thereby improving the balance and safety factor of the working platform of the electric hanging baskets, and reducing accidents and personal injuries. Casualties are of great significance and belong to the field of balance control of hanging platform working platforms in electrical automation. Background technique

[0002] Accidents of various sizes occur frequently during the construction process of the hanging basket hoist. According to incomplete statistics, in recent years, there have been nearly a hundred accidents caused by hanging baskets in the construction market every year, some of which are caused by the inclination of the working platform due to the incomplete synchronization of the motor speeds of the left a...
