Elevator car overload detection system

Abstract

The invention discloses an elevator car overload detection system. The elevator car overload detection system comprises a lift driving mechanism and a car which are arranged inside an elevator shaft;the lift driving mechanism is provided with a power storage device; the lift driving mechanism is fixedly connected with the car and comprises a main driving device and a partial guide wheel, whereinthe main driving device and the partial guide wheel are arranged inside the elevator shaft; the main driving device and the partial guide wheel are intertwined with a main cable; one end of the main cable is used for hanging the car, and the other end of the main cable is used for hanging a weight block; the lower part of the car is provided with a weight detecting component; the weight detectingcomponent comprises a weighing unit, a calculator, a controller, an executor and an alarming machine which are electrically connected with one another through a circuit; and the weighing unit comprises a displacement sensor and an elastic mechanism which are arranged at the upper part of a base plate of the car. The elevator car overload detection system disclosed by the invention is simple in structure, can be used for detecting the load of the car by utilizing a simple physical structure and alarming in time so as to prevent casualties caused by unstable running of an elevator.

Description

Technical field: [0001] The invention relates to the technical field of elevator detection, in particular to an elevator car overweight detection system. Background technique: [0002] With the increase of urbanization rate and economic development, there are more and more high-rise buildings. As an important means of transportation in buildings, elevators have been widely used in people's lives. They work around the clock to send users to their designated floors. Common elevators are divided into two types, one is a vertical elevator powered by a motor, equipped with a box-like gondola, which is used for multi-storey buildings to take people or carry goods; the other is stepped, and the tread plates are mounted on the crawler belt. Continuous operation, commonly known as automatic elevator. In order to improve the safety of elevator operation and ensure the personal safety of users, the elevator will be equipped with an overweight detection system, but the existing detecti...
