Active control system and method for flexible guide rail rope deflection

Abstract

The invention discloses an active control system and method for flexible guide rail rope deflection and belongs to guide rail rope control systems and methods. According to the system, the upper end of a lift car is connected with a lifting rope which penetrates through a drive wheel; the upper end and the lower end of the lift car are each connected with two lift car guide ropes symmetrically; a lift car elastic bumping block is further connected to the junction of the lift car and each lift car guide rope; the number of four-bar mechanisms is four, the four four-bar mechanisms are connected with the four lift car guide ropes correspondingly, and the other end of each four-bar mechanism is connected to a shaft wall; the portion, between the upper four-bar mechanism and the lower four-bar mechanism on each side, of the shaft wall is connected with an electromagnetic acting system; the junction of each four-bar mechanism and the corresponding lift car guide rope is connected with a connection rope and a four-bar mechanism pull rope, wherein the other end of the connection rope is connected with a connection rope guide pulley, and the other end of the four-bar mechanism pull rope is connected with a pull rope guide pulley; and an electric control system is electrically connected with the electromagnetic acting systems. The active control system is installed in the narrow shaft wall and is suitable for lift cars of different heights, and by adoption of the electromagnetic action control system, the lift car can operate more stably and safely.

Description

technical field [0001] The invention relates to an active control system and method for the deflection of a flexible guide rail rope, and is especially suitable for suppressing the deflection of the guide rope when a lifting container runs up and down along the flexible guide rope. Background technique [0002] With the gradual increase of coal seam mining depth, the tank way of underground hoisting and transportation equipment gradually transitions from rigid tank to flexible tank. The flexible guide rope is used for underground lifting because of its material saving, low economic cost and simple structure. guiding device. The hoist shaft uses a tensioning device to pre-tighten the guide rope. As the depth of the hoistway increases, the difficulty of pre-tightening the guide rope increases to ensure safety. It cannot be guaranteed that the tension of the steel wire rope per 100m is not less than 1t and the safety factor meets the specified requirements. If the pre-tighteni...
