Screw rod drive type lift with annular handrail

Abstract

The invention provides a screw rod drive type lift with an annular handrail. The screw rod drive type lift comprises a lift car, a screw rod capable of rotating around the axis is assembled at the lower part of the lift car, a drive module capable of driving the screw rod to rotate is assembled at the lower part of the lift car, a fixing ring fixed to a building is connected to the lower part of the screw rod in a threaded mode, the annular handrail is assembled inside the lift car, a control circuit is designed inside the handrail, the handrail is connected to a circuit through a pluggable plug, a manual shaft penetrating through a wall of the lift car is designed at the bottom of the handrail, the end of the manual shaft is connected to one end of a chain through a chain wheel in a tensioned mode, and the other end of the chain is connected to the drive module through the chain wheel and a drive shaft. According to the lift, the screw rod is adopted, special lift locking structures are not needed, and use is safer; the annular handrail is more convenient to use, and users can operate the lift conveniently on the conditions of power failures and unattended processing.

Description

Technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a screw-driving circular escalator. Background technique [0002] The elevator is a kind of vertical elevator powered by a motor. The traditional motor is equipped with a box-shaped pod, which is used as a transportation tool for people or goods in multi-storey buildings. Today's elevators are mostly used in high-rise buildings. Generally, a steel cable sling structure is used. Such a transmission structure requires a special sling structure to be designed on the upper part of the elevator, and a special hoistway needs to be designed at the same time, and the structure is more complicated. When traditional elevators are in use, they usually design the elevator control panel directly inside the car. Nowadays, with the improvement of people's living standards, people's living environment has been greatly improved. There are more and more families living in villas. It is ...
