A multi-rope friction hoist

Abstract

A multi-rope friction type elevator comprises a power mechanism, a friction wheel, head sheaves, a steel rope, an elevating container and a tail rope. The power mechanism drives the friction wheel to rotate through a main shaft. The main shaft is supported on a tapered-hole self-aligning roller bearing. A disassembly and assembly device for the tapered-hole self-aligning roller bearing is arranged on the main shaft. The disassembly and assembly device comprises a hydraulic ring, a bearing ring and a fixing ring which are sequentially arranged on the main shaft in a sleeving manner in the axial direction of the main shaft. A torque transmission device is arranged between a hub of the friction wheel and a shaft flange of the main shaft. The torque transmission device comprises a left pressing plate, a right pressing plate, a high-strength bolt set and an anti-rotating pin. According to the disassembly and assembly device, pressure oil is injected into different oil cavities, and radial pressure and axial pressure are successively generated, so that quick assembly and disassembly of the tapered-hole self-aligning roller bearing are achieved, the overhaul efficiency of the equipment can be improved greatly, balanced transmission of the radial heavy load can be achieved through the torque transmission device, and the reliability of large torque transmission between the friction wheel and the main shaft is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, in particular to an extra-large multi-rope friction hoist. Background technique [0002] Multi-rope friction hoist is one of the key equipment in the production of large and super large coal mines in my country, mainly used to lift coal, ore and transport personnel, materials and equipment. It is an important means of transportation connecting the well and the underground, and occupies a very important position in mine production. [0003] With the development trend of large-scale and high-yield mines in my country, the existing multi-rope friction hoist has the disadvantages of high failure rate, long shutdown and maintenance time, large amount of equipment maintenance, and high cost of spare parts, which increases the investment of mines. The cost has seriously restricted the development of mines, so there is an urgent need for ultra-large friction-type lifting equipment for 10-million-ton ...

[0003] With the development trend of large-scale and high-yield mines in my country, the existing multi-rope friction hoist has the disadvantages of high failure rate, long shutdown and maintenance time, large amount of equipment maintenance, and high cost of spare parts, which increases the investment of mines. The cost has seriously restricted the development of mines, so there is an urgent need for ultra-large friction lifting equipment for 10 million-ton mines with advanced technology, reliable performance, high efficiency and energy saving
