Description
Technical Field
The utility model relates to a mine winder technical field, in particular to rope clutch is transferred to multi-cylinder for single rope winding formula hoist.
Background
The mine hoist is one of important and key equipment of a mine, and is mainly used for hoists and lowering personnel for coal mines, metal ores and non-metal ores, hoisting coal, ores and transporting materials and equipment. It is an important transportation vehicle connecting the well and the underground. The throat plate is a very important place in mines and is an important throat device of the mines.
At present, the types of hoisting machines used mainly include multi-rope friction hoisting machines and single-rope winding hoisting machines. The rope adjusting clutch is only used for a single-rope double-drum winding type hoister and is a critical component. For a single-rope double-drum hoister, a moving winding drum can rotate relative to a main shaft through a bearing bush, a fixed winding drum is connected with the main shaft into a whole through a bolt, and when the hoister normally works, a rope adjusting clutch is meshed with a gear ring arranged on the moving winding drum, so that torque is transmitted to the moving winding drum from the main shaft, and the normal hoisting of the hoister is completed. After the elevator works for a long time, the steel wire rope extends or the production requirement needs to be replaced, the rope length needs to be adjusted to ensure that the double containers accurately reach a parking position, and at the moment, the double containers are connected with or separated from the gear ring through the clutch, so that the moving winding drum and the fixed winding drum synchronously rotate or do relative motion to adjust the rope length or replace the level.
At present, the structure of a commonly used rope adjusting clutch in China is shown as an attached drawing 1. The gear block type interlocking valve mainly comprises a gear block, a gear ring, an oil cylinder, a movable hub, an interlocking valve and the like.
The working principle of the rope adjusting clutch is as follows: when the elevator normally works, the tooth block and the gear ring are in a meshing state, the driving oil cylinder is in an oil return state, and an oil way entering the driving oil cylinder is closed, so that the tooth block and the gear ring are reliably meshed. When the rope is adjusted, the hoister is in a safe braking state; the high-pressure oil enters the leaving cavity of the driving oil cylinder, the gear block is disengaged from the gear ring by means of the movable hub, and the movable winding drum and the fixed winding drum can be in a relative motion state. Braking the floating drum, starting the hoister at low speed, fixing the drum to rotate, making the floating drum static, and adjusting the length of the steel wire rope or changing the steel wire rope to a required hoisting level to finish the rope adjusting operation.
The rope adjusting clutch has the disadvantages that when torque is transmitted, the tooth block has a downward disengaging trend due to downward force, once oil is fed due to misoperation or failure in the lifting process, the tooth block is disengaged from the gear ring, the floating winding drum and the main shaft are in a relative rotation state, the lifting steel wire rope and a heavy object fall down in an accelerating way under the action of gravity, and a serious container falling accident occurs.
In the practical use process, due to the limitation of factors such as installation and the like, the number of teeth on the tooth block is about 1/10 of the number of teeth on the gear ring, when the specification of a hoisting machine and the hoisting load are large, the torque required to be transmitted by each tooth of the tooth block is increased sharply, and the size is increased correspondingly. In order to accurately transmit torque, the backlash and the gap difference between the gear block and the gear ring of the gear block and the meshing teeth need to be strictly controlled, the installation and the adjustment are difficult, and the high-precision requirements of all the teeth are difficult to guarantee simultaneously.
In order to complete the disengagement and engagement of the gear block, the moving hub, the stirring ring and other parts need to be installed on the hub, in order to ensure the stability of installation and operation, the size of the hub is large, and the hub needs to be hot-assembled with the main shaft, so that the structural size of the main shaft and the overall assembly of the main shaft device are limited, and the weight of the whole main shaft device is increased.
