Abstract

A collision-proof freight elevator with a blind spot monitoring function belongs to the technical field of elevators, and comprises a car that can move up and down in a shaft, a monitoring gate fence for monitoring the objects being carried, and a control box for controlling the operation of the freight elevator; an entrance car door and an exit car door are respectively arranged on opposite sides of the car, and an entrance floor door and an exit floor door are respectively arranged on the side of each floor opposite to the car where the entrance car door and the exit car door are arranged; a monitoring area is arranged on the side of the entrance floor door of each floor facing away from the car, and the monitoring gate fence is arranged at the end of the monitoring area farthest from the entrance floor door; the distance between the front end and the front end wheel of a cargo transport vehicle can be measured through the cooperation of an AI camera, a transmitter, a receiver and a pressure sensing strip, so as to control the action of a blocking device, so that the cargo transport vehicle is stopped on the outside of the entrance floor door, so as to avoid collision between the cargo or the transport vehicle and the entrance floor door of the freight elevator.
