Electric steel wire rope balancing device and lifting method for vertical full-balance steel wire rope hoisting winch

Abstract

The invention discloses an electric steel wire rope balancing device and a lifting method for a vertical full-balance steel wire rope hoisting winch. The vertical full-balance steel wire rope hoisting winch comprises winch equipment and hoisting steel wire ropes, and one end of each hoisting steel wire rope is wound on the winch equipment while the other end of each hoisting steel wire rope is connected with a to-be-hoisted article. Two disconnected steel wire ropes can be connected to form one hoisting steel wire rope by the electric steel wire rope balancing device, the electric steel wire rope balancing device can be started for pre-pressurizing the hoisting steel wire ropes, pre-stress of each hoisting steel wire rope is adjusted to balance stress of each hoisting steel wire rope by measuring stress conditions of the pre-stressed hoisting steel wire ropes. The electric steel wire rope balancing device and the lifting method for the vertical full-balance steel wire rope hoisting winch have the advantages of simple structure, convenience in maintenance, reliability in performance and capability of hoisting articles more than 4000 tons.

Description

technical field [0001] The invention belongs to the force bearing technology of a motor reducer driving a balanced steel rope, and is used for a method for hoisting a steel rope to vertically lift a heavy object. Background technique [0002] It is difficult to control the balance when lifting objects that are more than 1,000 tons vertically. Take the vertical ship lift as an example. Generally, the fully balanced steel wire rope winch vertical ship lift uses the winch as the lifting device. The winch motor, large torque It is composed of reducer and reel. A hoisting wire rope is wound on the drum, and one end of the wire rope is connected with the ship bearing box, and the other end is connected with the balance weight. During the lifting process of the ship lift, due to the influence of many factors such as the diameter and ellipticity deviation of the drum and the wire rope, the lengths of the hoisting wire ropes are not equal, and the force is not balanced, and the leve...

Problems solved by technology

Although the hydraulic equalization system is widely used, there are still many deficiencies as follows: the hydraulic equalization subsystem of the ship lift is a first-order feedback system, and there is a huge difference in the modeling method between the hydraulic equalization subsystem of the ship lift and the second-order structural subsystem such as the mechanical lift. Find its dynamic response; under the influence of the external environment, the temperature of the hydraulic oil changes, which will affect the stability of the drive; if the oil leaks or the oil is polluted, maintenance work is required, and the maintenance work is more complicated and requires professional technicians
