Automatic oil injection system for head sheave of multi-rope friction-type elevator

Abstract

The invention discloses an automatic oil injection system for a head sheave of a multi-rope friction-type elevator, and belongs to the technical field of oil injection equipment. Fixed wheels are fixedly mounted on a head sheave main shaft. One side of each fixed wheel is provided with a plurality of traveling sheaves. The traveling sheaves are mounted on the head sheave main shaft through bearingbushes. A main oil channel is formed in the axial center position of one end of the head sheave main shaft. Oil separating channels communicating with the main oil channel are formed in the positions, opposite to the bearing bushes, of the outer circumferential surface of the head sheave main shaft. An end opening of the main oil channel is provided with a rotating joint. The rotating joint is rotationally mounted at the end of the head sheave main shaft. A through hole communicating with the end opening of the main oil channel is formed in the axial center of the rotating joint. The other end of the through hole of the rotating joint is connected with an oil pipe. The other end of the oil pipe is connected with an oil injection pump. According to the automatic oil injection system for the head sheave of the multi-rope friction-type elevator, the oil injection time and the oil injection amount can be controlled, and the effects of refined and automated lubrication are achieved; moreover, automatic oil injecting can be achieved under the situation that the multi-rope friction-type traveling head sheave works dynamically; and specific control can be completed on a site, and remote control can further be achieved in a hoist house.

Description

technical field [0001] The invention relates to a multi-rope friction hoist sky wheel oiling device, in particular to an automatic oil injection system for a multi-rope friction hoist sky wheel. Background technique [0002] One of the sky wheels of the multi-rope friction hoist is a fixed wheel, and the others are floating wheels. The fixed wheel and the sky wheel shaft are connected by a flat key, and the inner hole of the traveling wheel is equipped with a bearing bush to enable the flexible rotation between the traveling wheel and the sky wheel main shaft. wear, avoid excessive wear of the liner, and protect the wire rope. The relative rotation between the bearing bush and the main shaft of the sky wheel belongs to sliding friction, so it will generate huge friction force. In order to ensure the normal operation of the traveling wheel, the bearing bush must be sufficiently lubricated, otherwise the two metals will glue and wear, which is inevitable. It brings about cha...

Problems solved by technology

The relative rotation between the bearing bush and the main shaft of the sky wheel belongs to sliding friction, so it will generate huge friction force. In order to ensure the normal operation of the traveling wheel, the bearing bush must be sufficiently lubricated, otherwise the two metals will glue and wear, which is inevitable. It brings changes in the thickness of the copper tiles, and at the same time causes the diameter difference of each set of traveling wheels to increase, which will eventually wear faster and faster

The sky wheel of the multi-rope friction hoist is one of the important facilities in the hoisting system. Once there is a problem with it, it will stop production at least, and cause a safety accident at worst.

[0003] Since the top wheel of the multi-rope friction hoist is located on the upper part of the high well tower, it is extremely inconvenient to inspect, maintain and replace. Oil injection is carried out through the oil injection port on the top of the machine. This oil injection method is time-consuming and laborious, and it is particularly harmful to the physical and mental health of the operators.

In addition, it is difficult to accurately grasp the amount of manual oil injection and the timeliness of oil injection. These factors have brought huge hidden dangers to safe production and personal health.
