Double-cylinder articulated multi-rope winding type hoist

Abstract

The invention discloses a dual-drum articulated multirope winding hoisting machine, which mainly consists of a main shaft unit 1, a disc brake 2, a universal coupling 3, a hydraulic station 4, an operation desk 5 and motors 6. The main shaft unit is arranged on and respectively fixed with a bearing support 7, and articulated by the universal coupling, other ends thereof are linked with the motor for carrying out synchronous direct connection drag, the two ends of an assembled braking disc 1.1 are provided with the symmetrical disc brake, the hydraulic station is used for providing brake pressure, and the two motors and the hydraulic station are controlled by the operation desk. The main shaft unit consists of the assembled braking disc, a fixed wound roll 1.2, a plastic lining board 1.3, a rope-retaining board 1.4, the main shaft 1.5 of the fixed wound roll, a rope-adjusting clutch 1.6, a nomadic wound roll 1.7, a left hub 1.8, two halves of brasses 1.9, the main shaft 1.10 of the nomadic wound roll and a right hub 1.11, wherein, the main shafts of the fixed wound roll and the nomadic wound roll are not in the same center line and have an included angle of 5 to 10 degrees. When inworking, a container is lifted by two cable wires, thus effectively meeting the lifting needs.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, in particular to a double-tube articulated multi-rope winding hoist. Background technique [0002] Mine hoist is one of the important and key equipment in mines. It is mainly used in coal mines, metal mines and non-metal mines for 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 X1 type to JKA type, and from XKT type, XKTB type to the current JK type formed product. [0003] The working principle of the single-rope winding hoist is as follows: each lifting container is lifted by a wire rope, one end of the wire rope is fixed and wound on the...

AI Technical Summary

Problems solved by technology

[0006] 1) When the deep well is hoisted or the hoisting load is large, the diameter of the steel wire rope is required to be large, and the manufacture and use of large-diameter steel wire ropes are inconvenient

[0007] 2) Each lifting container is lifted with only one wire rope, and serious accidents will occur when the wire rope breaks

[0008] 3) The width of the hoist drum directly affects the rope capacity and hoisting depth of the hoist, but increasing the width of the drum will increase the width of the shaft, thereby increasing the mine construction cost

[0009] 4) The hoist is driven by a motor through an elastic pin coupling, a planetary reducer and a gear coupling, with a complex structure and a large footprint

[0011] 6) Due to the limitation of the reel structure, only one wire rope can be wound on a reel
