Abstract

The invention provides an elevator maintenance bottom pit supporting device. The elevator maintenance bottom pit supporting device comprises a supporting column, a cavity, an air pressure device, a main supporting device and auxiliary supporting devices; the supporting column is vertically arranged in an elevator bottom pit and internally provided with the cavity; the air pressure device is fixedto the bottom of the interior of the cavity; the main supporting device is arranged on the upper portion of the interior of the cavity, and the bottom of the supporting device is fixedly connected with the upper end of an output shaft of the air pressure device; the two opposite side walls of the supporting column are provided with the auxiliary supporting devices; and the main supporting device is in transmission connection with the auxiliary supporting devices. The elevator maintenance bottom pit supporting device further comprises a transmission device, a controller, an infrared distance measuring sensor and a speed sensor, wherein, the transmission device is arranged between the main supporting device and the auxiliary supporting devices, the infrared distance measuring sensor is arranged at the top end of the supporting column, the speed sensor is arranged on an elevator car, the infrared distance measuring sensor and the speed sensor are in communication connection with a controller, and the controller is in signal connection with the air pressure device. The elevator maintenance bottom pit supporting device is ingenious in structural design, high in supporting stability andintelligent degree and capable of providing a safe maintenance environment for maintenance personnel.

Description

technical field [0001] The invention belongs to the technical field of elevator maintenance, and in particular relates to a support device for an elevator maintenance pit. Background technique [0002] Elevators are passenger equipment used in high-rise buildings. They can take passengers to designated floors and are very convenient to use. The elevator needs to be maintained and repaired daily to ensure the safety of the use process. When maintenance personnel maintain the elevator, they need to enter the elevator bottom pit to perform operations. In order to provide maintenance personnel with a certain maintenance space, it is often necessary to lift the elevator car to a certain height and maintain the car at this height stably. However, when the maintenance personnel are maintaining in the elevator pit, there is still the danger of life caused by the falling of the elevator. [0003] Therefore, how to provide a support device that can support the elevator car in time ...
