Automatic dismounting device for elevator car door sheet

Abstract

The invention discloses an automatic dismounting device for an elevator car door sheet. The automatic dismounting device comprises a supporting plate, wherein two first hydraulic cylinders are weldedto one side of the supporting plate, two second hydraulic cylinders are welded to the other side of the supporting plate, the top ends of piston rods of the first hydraulic cylinders and the top endsof piston rods of the second hydraulic cylinders are connected with the bottom of a placing plate, the end, at the second hydraulic cylinders, of the placing plate is connected with a right-angle frame, and the right-angle frame and the placing plate form a groove structure; and screw rods are arranged below the supporting plate, two ends of the screw rods are connected to the supporting plate through bearings, one ends of the screw rods penetrate through the supporting plate to be connected with cranks, each screw rod is in threaded connection with two groups of threaded sleeves, each group of thread sleeves comprise two threaded sleeves, the thread directions of each group of threaded sleeves are opposite, each group of the threaded sleeves are connected with a connecting block through afirst connecting rod and a second connecting rod, and universal wheels are mounted on the lower surfaces of the connecting blocks. The device is convenient to use, manpower is saved, the safety is high, the movement and placement states of the device can be conveniently adjusted, and the door sheet can be conveniently dismounted.

Description

technical field [0001] The invention relates to the technical field of unloading devices, in particular to an automatic unloading device for elevator car door panels. Background technique [0002] At present, most of the long-distance transportation of materials is carried out by trucks, and unloading devices are required when they arrive at the destination point for delivery. The elevator car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of main components such as the car bottom, car wall, car roof, car door (door panel), and its internal net height is from the car bottom to the car. The distance from the top should be at least 2m. [0003] At present, the unloading of the door panels of the elevator car is done manually, which has low safety. The operator and the door panel itself are vulnerable to damage. Some will build a slanting plate to guide the door panel and assist it to get out of the car buc...

Problems solved by technology

[0003] At present, the unloading of the door panels of the elevator car is done manually, which has low safety. The operator and the door panel itself are vulnerable to damage. Some will build a slanting plate to guide the door panel and assist it to get out of the car bucket. Unloading, the efficiency is low, and the door needs to be moved to the transfer device after unloading, which is very inconvenient to use
