Problems solved by technology

In order to improve the safety of elevator operation and ensure the personal safety of users, the elevator will be equipped with an overweight reminder, and an alarm will be issued once an overweight situation occurs. The existing overweight alarm detection device is not only complicated in structure, expensive in cost, and relatively low in accuracy. If the overweight in the elevator car cannot be detected in time, it will affect the operation of the elevator and reduce the stability of the elevator operation

Abstract

The invention discloses an elevator overweight detecting and alarming device which comprises a lifting driving mechanism and an elevator car, wherein the lifting driving mechanism and the elevator carare arranged in an elevator shaft; a swinging detecting assembly is arranged on a main cable at the upper end of the elevator car, and comprises a pressure sensor, a calculator, a controller, an actuator and an alarm; an omega-shaped bracket is fixed on a wall of the elevator shaft; two sides of the omega-shaped bracket are fixedly connected with the wall through fastening screws; a pressure sensor holding frame is detachably connected with one side surface of the omega-shaped bracket; the flexible pressure sensor is arranged on the pressure sensor holding frame; one end of the pressure sensor holding frame is connected with the omega-shaped bracket; a pull rod is connected with the upper part of the other end of the pressure sensor holding frame through a connecting part; a guide pulleygroup is arranged at one end part of the pull rod, and comprises a first guide pulley and a second guide pulley; a groove part used for the penetration of the main cable is arranged between the firstguide pulley and the second guide pulley; the first guide pulley and the second guide pulley are connected through a connecting frame; and the pull rod penetrates through and is guided by a horizontally-arranged sleeve.

Description

Technical field: [0001] The invention relates to the technical field of elevators, in particular to an elevator overweight detection and alarm device. Background technique: [0002] With the improvement 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 and send users to their designated floors. In order to improve the safety of elevator operation and ensure the personal safety of users, the elevator will be equipped with an overweight reminder. Once the overweight situation occurs, an alarm will be issued. The existing overweight alarm detection device is not only complicated in structure, expensive in construction, and relatively low in accuracy. If the overweight in the elevator car cannot be detected in time, it will affect the operation of the elevator and reduce the stability of the elevator operati...
