Abstract

The invention provides an elevator non-load balance coefficient detection device with the hydraulic cylinder pressure detection function. The elevator non-load balance coefficient detection device comprises an upper clamp, hydraulic cylinders and a lower clamp. The upper clamp is directly installed above the hydraulic cylinders. The lower clamp is directly installed below the hydraulic cylinders. The hydraulic cylinders are used for lifting the lower clamp. The hydraulic cylinders are connected with a hydraulic pump through a hydraulic pipe. A pressure sensor is arranged on the hydraulic pipe so as to detect pressure of hydraulic media in the hydraulic pipe. As the pressure sensor is connected to the hydraulic pipe of the hydraulic cylinders, the pressure of the media such as hydraulic oil in the hydraulic cylinders can be automatically detected in real time and displayed so as to be directly and conveniently observed, or other parameters such as tension of the hydraulic cylinders are further calculated through the pressure.

Description

technical field [0001] The invention relates to the technical field of elevator parameter detection, in particular to an elevator no-load balance coefficient detection device with a hydraulic cylinder pressure detection function. Background technique [0002] The balance factor is an important performance index of the traction drive elevator, which is related to the elevator's operating performance and the output power of the traction motor. About 400,000 new elevators are installed and used in China every year, among which traction elevators account for more than 90%. Each new traction elevator should be tested and adjusted for balance coefficient. Only when the balance coefficient index is qualified can it be put into use. In addition, the decoration of the elevator by the user affects the change of the balance coefficient, and the balance coefficient must be re-measured. Therefore, the detection of balance coefficient is a large-volume, wide-ranging and demanding technic...
