Description

Automatic control system of material hoister
Technical Field
The invention relates to the technical field of building hoist control, in particular to an automatic control system of a material hoist.
Background
In construction sites, factories and places where goods need to be transported up and down, the most common way is to construct a tower frame by steel, embed a vertically movable suspension cage or platform, and control the vertical movement of the suspension cage from the ground to the high altitude by controlling the forward and reverse rotation of a winch to pull a steel wire rope. There are generally three methods for the cage to stop at different floors: 1. the method is realized by cutting off the power supply of the winch after an operator visually inspects that the cage reaches a specified position, and the deviation of the position is very large because the cage is completely manually parked; 2. travel switches are installed on all floors to serve as floor sensors, and connecting lines are required to be arranged on the tower frame or the suspension cage; 3. with coded switches, only below 10 layers can be accommodated due to the limitations of the switch bank. In addition, due to factors such as inertia of the hanging basket from movement to stop, pulling of a traction steel cable, axle-holding slipping of brake shoes and the like, the deviation between the plane of the hanging cage and the plane of a floor is large, the loading and unloading are inconvenient due to the deviation height, and particularly when the trolley is used for loading and unloading, the problem is more prominent. The inertia of the ascending parking is much smaller than that of the descending parking when the same weight is loaded, which brings certain difficulty to the control of the parking.
