Hoisting steel belt and elevator hoisting system comprising the hoisting steel belt

Abstract

The invention discloses a lifting steel belt and an elevator lifting system comprising the same. The lifting steel belt is composed of a plurality of steel wire ropes and a wrapping layer wrapping the steel wire ropes into a whole, and at least one surface of the lifting steel belt is a continuous arc-shaped guide surface protruding outwards. A pulley used cooperatively with the lifting steel belt is provided with an arc-shaped guide groove which is sunk inwards, and the arc radius of the arc-shaped guide groove is matched with the arc radius of the corresponding arc-shaped guide surface of the lifting steel belt. The lifting steel belt is convenient to install and can be centered automatically, the phenomenon that the lifting steel belt deflects is avoided completely, the stress state of the lifting steel belt is improved, the service life of the lifting steel belt is prolonged, vibration is reduced, and noise is lowered. In addition, the problem that slippage cannot be achieved due to the fact that the friction coefficient between a concave-convex steel belt or a v-ribbed belt and the pulley is large can be solved, and the lifting steel belt facilitates long-time running of an elevator.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a hoisting steel belt capable of realizing the hoisting function. The hoisting steel belt is mainly used as an elevator traction, bearing, suspension and hoisting component. Background technique [0002] As a vertical transportation tool, elevators are closely related to modern social life. With the development of social economy and the acceleration of urbanization, there are more and more high-rise buildings, and high-rise buildings have become a city symbol, some even Become a landmark of the city. With the emergence of high-rise buildings and the development of social culture, the demand for elevators is becoming stronger and stronger, especially in today's aging society, the significance of elevators is even more important. Elevators all over the world are in operation every day, carrying a large number of people and logistics transportation. The role of elevators in buildings has b...
