Power transmission method of high-efficiency energy-saving elevator

Abstract

The invention relates to a power transmission method of a high-efficiency energy-saving elevator. According to a power transmission scheme, two large chain wheels on the upper portion of a roof bear the elevator, and also have a power driving function and a transmission guiding function; and two large chain wheels on the lower portion of a bottom have a chain wheel center distance adjusting function, bear part of the elevator and have a transmission guiding function. A function allocation scheme in the design can meet requirements of a mechanical design principle; two chain wheel seats on the lower portion of the bottom are modified into sliding seats capable of sliding vertically, and the heights of the sliding seats can be adjusted hydraulically; the sliding seats are connected to a piston rod of a single-piston cylinder below the sliding seats; and a base of the single-piston cylinder is connected to a horizontal seat surface in a hinged manner. By the seats, a center distance between the upper chain wheel and the lower chain can be adjusted in time according to tension detection of chain cables and horizontal height comparison detection of two ends of each seat, and power transmission of the high-efficiency energy-saving elevator is in an optimal mechanical state during working of the high-efficiency energy-saving elevator; and the elevator can work smoothly, stably and safely, and noises are small.

Description

technical field [0001] The invention relates to an elevator, in particular to a power transmission method for a high-efficiency energy-saving elevator. technical background [0002] In order to adapt to the development trend of modern population to urban filling, to facilitate and meet the living needs of urban population living buildings, and to better adapt to and complete the task of transporting up and down modern high-rise buildings, people have been researching and inventing 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 height of the building into two vertical line segments and two vertical lines between the height of the building. It is a plane closed-loop combined line composed of three arcs, which is a circular operation elevator. I...

[0005] The high-efficiency energy-saving elevator has the advantages of large capacity, high efficiency and energy saving, and can save a lot of building area resources. It adapts to the development trend of modern high-rise buildings and has great market development prospects. As a high-performance elevator, it should be more technically refined, especially There should be more detailed considerations in the power transmission, just imagine: in a 600-meter-high building, a high-efficiency energy-saving elevator announced by CN104129696 A is installed, and the influence of temperature changes on the total length of the chain cable elongation throughout the year is fixed. There is obviously something wrong with the center distance of the type chain cable wheel. If the center distance of the power transmission of the upper and lower sprockets is not suitable for the total length of the chain cable, it will affect the quality of the elevator's operation. To the safe operation of the elevator
