Abstract

The invention provides an elevator zero load balancing coefficient detecting device. The device comprises an upper clamp, hydraulic cylinder components , a lower clamp and tension sensors, wherein the upper clamp is installed above the hydraulic cylinder component and is used for clamping the upper part of a hoisting rope section selected; the hydraulic cylinder components are used for lifting the lower clamp; the lower clamp is installed at the lower part of the hydraulic cylinder components and is used for clamping the lower part of the hoisting rope section selected; the tension sensors are used for measuring the tension of the hydraulic cylinder components. The elevator zero load balancing coefficient detecting device adopts the hydraulic cylinder components as a load measuring device, and sufficiently utilizes the characteristics of operation stability and reliability of the hydraulic cylinder components, thereby having the advantages of simpleness in operation and high safety performance during operation, and meanwhile the accuracy of measured data of the hydraulic cylinder components is higher.

Description

technical field [0001] The invention relates to the technical field of elevator detection, and in particular, the invention particularly relates to a detection device for an elevator no-load balance coefficient. Background technique [0002] The balance coefficient is an important performance index of the traction drive elevator, which is related to the elevator running performance and the output power (energy consumption) of the traction motor. About 400,000 new elevators are installed and used in my country every year, of which traction elevators account for more than 90%. Each of these new traction elevators must be tested and adjusted for balance coefficients. Only when the balance coefficient is qualified can it be put into use. In addition, more and more users decorate the elevator, and the decoration of the car affects the change of the balance coefficient, so the balance coefficient must be re-measured. Therefore, the detection of balance coefficient is a large-volu...
