Multi-stage speed reducer for vertical shaft flexible hoisting container

Abstract

The invention discloses a multi-stage speed reducer for a vertical shaft flexible hoisting container, and belongs to the technical field of vertical shaft hoisting transportation. The multi-stage speed reducer comprises a flexible hoisting container, wherein guide rollers are arranged on the left side and the right side of the flexible hoisting container, guide rails matched with the guide rollersare arranged on the left side and the right side of a vertical shaft, and the guide rollers are arranged on the guide rails in a rolling mode; and front and rear symmetrical speed reducers are arranged on the front and rear sides of the flexible hoisting container, the plurality of speed reducers are arranged in the ascending and descending direction of the flexible hoisting container, and the braking torque of the speed reducers at the upper side is smaller than that of the speed reducers at the lower side. According to the multi-stage speed reducer for the vertical shaft flexible hoisting container, multi-stage speed reducing braking is adopted, so that tensile stress or compressive stress generated on the flexible hoisting container due to single use of upper disc braking or lower discbraking is avoided; and the multi-stage speed reducing braking force is decreased progressively from top to bottom, and the balance between the overall inertia pressure and pulling force of the flexible hoisting container is maintained so that the perpendicularity of the flexible hoisting container can still be guaranteed through the dead weight, and the container is prevented from twist deformation and getting stuck in the middle of a shaft.

Description

technical field [0001] The invention relates to the technical field of shaft hoisting and transportation, in particular to a multi-stage deceleration device for a shaft flexible hoisting container. Background technique [0002] As the mine shaft hoisting system continues to increase, the hoisting container is also increasing, but the corresponding shaft section cannot be increased without limit. After increasing the load, the section of the hoisting container does not increase much, and the height of the container can only be increased, and the height of the container can even reach 23 meters, the container structure has also changed from the original rigid container to a flexible container, and the verticality is guaranteed by the self-weight of the container. In this way, if the original bottom braking is continued, due to the large braking force and the height of the container, after the bottom of the container is stressed, the overall pressure resistance of the flexible ...

Problems solved by technology

[0004] Although it reduces the twisting and deformation of the flexible lifting container through the upper disc braking, only the upper disc braking will still cause the lower end of the flexible lifting container to swing, and because the flexible lifting container has a large inertia, the upper disc braking will have a negative impact on the flexible lifting container. The tensile stress is also large, which is easy to cause damage to the drawstring
