Safe, high-efficiency and energy-saving elevator and manufacturing method thereof

Abstract

The invention discloses a safe, high-efficiency and energy-saving elevator. A constraint rail is increased on an arc operation section, multiple places are constrained, the elevator car refers to a composite elevator car with double nested boxes, the inner elevator car can move up and down in the outer elevator car, a cable chain wheel system comprises a bearing chain wheel and a matched chain cable, the chain cable refers to a rope formed by combining a chain and a cable into a whole, the 100-percent security constraint and security assurance of the total operation tracks can be realized, and the height position of the inner elevator car can be finely adjusted, so that the inner bottom plane of the inner elevator car is accurately flush with the ground level of the building, the personnel access and cargo handling can be conveniently realized, the advantages of the chain and cable are maintained, the defects of the chain and cables are overcome, the operation is stable and noise-free, buffer and vibration absorption can be realized, the defects of the existing technology are overcome, and the security assurance, stop position accuracy and operating stability of the multi-elevator car high-efficiency and energy-saving elevator are greatly improved.

Description

technical field [0001] The invention relates to an elevator, in particular to a safe, high-efficiency and energy-saving elevator and a manufacturing method thereof. technical background [0002] In order to make things convenient for and meet the living needs of urban population living buildings, and better adapt to and complete the task of transporting up and down modern high-rise buildings, people have tried various methods to research and invent various types of high-performance elevators. [0003] CN104129696 A has announced a kind of high-efficiency energy-saving elevator, and its technical scheme is to change the elevator that runs straight up and down in a vertical line segment between the traditional single car and the building height into two vertical line segments and two vertical line segments between the height of the building. It is a plane closed-loop combined line composed of three arcs, which is a circular operation elevator. It has a large capacity and high ...

AI Technical Summary

Problems solved by technology

However, there are minor flaws, and the scheme also has a fly in the ointment. There are three main ones: first, there are constrained orbits in the straight section and no restricted orbit in the arc section, so it is still doubtful whether 100% safety can be achieved; It is quite difficult for all the cars to run up and down synchronously and stop on floors with different running directions up and down. It is quite difficult to make all the cars stop at the precise positions of their respective floors; In terms of connection, there are two load-bearing parts on the left and right sides - chain and cable. The car load-bearing shaft in the middle deviates from the plane of the chain and cable on the outside of the load-bearing parts, and is tightly connected with it. There is torque, not a ideal option
