Synchronous head sheave balance adjustment method for multi-rope winding type elevator

Abstract

Disclosed is a synchronous head sheave balance adjustment method for a multi-rope winding type elevator. When the multi-rope winding type elevator works, a container is elevated by two steel wire ropes through head sheave bodies. In the elevating process of the container, when the force applied to the steel wire rope winding around a head sheave on a hydraulic cylinder is larger, the corresponding head sheave body is downwards compressed through the first hydraulic cylinder, so that the force is reduced, and meanwhile, the steel wire rope is loosened for adjustment to a force balance with the steel wire rope on the other side. When the force applied to the other steel wire rope is larger, the corresponding head sheave body 1 is compressed downwards through the second hydraulic cylinder, so that the force is reduced, and meanwhile, the steel wire rope is loosened. When the force applied to the two head sheave bodies is unbalanced, pressure compensation is generated to the hydraulic cylinders; when the first hydraulic cylinder is compressed, hydraulic pressure pressurizes the second hydraulic cylinder for a balance through a communication device, so that the pressure balance of the second hydraulic cylinder and the first hydraulic cylinder is achieved after pressurization; the tension of the steel wire ropes of the multi-rope winding type elevator can be balanced and compensation can be conducted for non-synchronization flexibly and conveniently.

Description

technical field [0001] The invention relates to a synchronous sky wheel of a mine hoist wound with wire ropes, in particular to a method for adjusting the balance of the synchronous sky wheel of a multi-rope winding type hoist. Background technique [0002] At present, the mine hoist is one of the important and key equipment in the mine, mainly used in coal mines, metal mines and non-metallic mines, hoists and decentralized personnel to lift coal, ore, and transport materials and equipment. It is an important means of transportation to connect the well and the underground. It occupies a very important position in the mine and is an important equipment of the mine. The mine hoist is developed from the hand potter's wheel. With the development of science and technology, the hoist has developed from the KJ type to the JKA type, and from the XKT type, XKTB type to the current JKZ type and the new multi-rope winding type. Mine hoist. [0003] The multi-rope winding mine hoist ...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the insurmountable shortcomings of the existing multi-rope friction hoist steel wire rope tension balance device when it is applied to the multi-rope winding mine hoist, which cannot satisfy the multi-rope winding hoist steel wire rope tension balance and Synchronization needs, through reasonable design, provide a synchronous sky pulley balance adjustment method for multi-rope winding hoist, which can flexibly and conveniently balance the wire rope tension of the multi-rope winding hoist and compensate for asynchrony; installed in the sky On the wheel, instead of reducing the payload at the end of the wire rope like the wire rope tension balance device of the multi-rope friction hoist, the ability of the wire rope to lift more payload means that the mine production unit can create more benefits
