An Elevator Device Applicable to Renovation of Old Buildings

Abstract

The invention relates to the field of lifting elevator equipment, in particular to an elevator device suitable for old building transformation. The elevator device comprises a car, an elevator hole, acover plate and a control mechanism; the control mechanism comprises a power shaft, first transmission shafts and second transmission shafts; a power input gear and a first cylindrical gear are fixedly arranged on the power shaft; racks are arranged at the top and the bottom of a car; first bevel gears and second cylindrical gears in engaged connection with the first cylindrical gear are arrangedon the two first transmission shafts; the two second transmission shafts are perpendicular to driving shafts, and are distributed on two sides of the two first transmission shafts; worm rods and second bevel gears in engaged connection with the first bevel gears on the corresponding sides are arranged on the two second transmission shafts; and the worm rods are in engaged connection with worm wheels fixed on the driving shafts on the corresponding sides. An elevator shaft is not additionally provided, and the elevator hole in a gallery is automatically opened and closed in the elevator operation, so that accidents easily caused by frequent opening of the elevator hole are prevented.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an elevator device suitable for renovation of old buildings. Background technique [0002] The installation of elevators is the focus of the renovation of old buildings in cities. The installation methods of elevators in the prior art mainly include external hanging type and built-in type. It is difficult to transform the external elevator, and the investment cost is high, and it will block the windows of some residents. The built-in type is usually installed in an old-fashioned residential building with door-to-door two households on the first floor, and the elevator is installed between the doors of the two households. However, after the elevator is installed, the elevator shaft needs to be added between the doors of the two households, which takes up limited corridor space. However, if the elevator shaft is not covered, there will be exposed elevator holes on the corridor ...
