Abstract

The invention provides an elevator load detection device which comprises at least one loading measuring group, a sensor display instrument, a computer and an intelligent hydraulic control device, wherein the computer is connected with the sensor display instrument and the intelligent hydraulic control device respectively; each loading measuring group comprises a tension sensor, a hydraulic oil cylinder and a basic embedded board; the top of each tension sensor is connected with a first steel wire rope; each first steel wire rope penetrates through a car bottom beam and is connected to the car bottom; the lower end of each tension sensor is connected with a piston vertical rod of the hydraulic oil cylinder through a second steel wire rope; and the bottom of each hydraulic oil cylinder is fixed on the corresponding basic embedded board. The invention also provides an elevator load detection method. The device provided by the invention is small in volume, light in weight, convenient to carry, strong in practicability, easy to operate and feasible; and the detected value is more reliable and accurate.

Description

【Technical field】 [0001] The invention relates to an elevator load detection device and a method thereof. 【Background technique】 [0002] With the rapid development of my country's economy, high-rise buildings have sprung up like mushrooms after rain. Elevator is an essential device for high-rise buildings. As a unique means of transportation, it has been rapidly popularized and developed. At the same time, the elevator is also a mechatronics product with high technical content. Because it fully uses computer control, intelligence and Electrical and electronic technology, so it has the characteristics of high technical content and rapid development. When high-rise buildings have higher and higher requirements for elevator performance and control systems, the corresponding safety protection systems are required to be more advanced and reliable. [0003] The overload protection function is an important protection function of the elevator. A large number of elevator accidents...
