Embodiment 1

[0028] A second hydraulic cylinder 4-1 is arranged symmetrically on one side of the first hydraulic cylinder 4, and a communication device 5 is arranged between the bottoms of the two hydraulic cylinders; a bearing bracket 6 is respectively arranged above the cylinder rods of the first hydraulic cylinder 4 and the second hydraulic cylinder 4-1 , the bearing bracket 6 is coaxially provided with two support plates, the two support plates are arranged symmetrically, the sky wheel body 1 is arranged between the two support plates, the sky wheel bearing 2 is arranged correspondingly in the middle of the support plate, and the sky wheel shaft 3 is arranged in the sky wheel bearing 2 ; When the multi-rope winding hoist is working, two steel wire ropes pass through the sky wheel body 1 to lift the container. When the container is in the lifting operation, when the steel wire rope wound by the sky wheel on the hydraulic cylinder 4 is stressed, the sky wheel body 1. The first hydraulic c...

Embodiment 2

[0030] When the other wire rope is stressed, the sky wheel body 1 is compressed downward by the second hydraulic cylinder 4-1 to reduce the stress and at the same time relax the wire rope, and the wire rope is relaxed to balance the force with the other side of the wire rope adjustment.

Embodiment 3

[0032] When the force on the two sky wheel bodies 1 is unbalanced, pressure compensation is generated for the hydraulic cylinder: when the first hydraulic cylinder 4 is compressed, the hydraulic pressure pressurizes the second hydraulic cylinder 4-1 through the communication device 5, and the pressurization makes the first hydraulic cylinder 4. Balance the pressure with the second hydraulic cylinder 4-1. When the first hydraulic cylinder 4 is compressed, the hydraulic pressure pressurizes the second hydraulic cylinder 4-1 through the communication device 5. After the pressurization, the second hydraulic cylinder 4-1 and the first hydraulic cylinder A hydraulic cylinder 4 is pressure balanced.

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 ...
