Rotary cap type lifting device for small building lift car

Abstract

The invention relates to a rotary cap type lifting device for a small building lift car. The rotary cap type lifting device for the small building lift car is characterized by comprising a lift car mechanism, rotary cap type mechanisms and a control mechanism; four well frame square pipes are arranged on the small building lifting ladder foundation, the rotary cap type mechanisms are arranged on the two sides of the lift car top of the lift car; umbrella-shaped rotary caps, plane bearings and a rotary cap positioning bearing are arranged in the rotary cap type mechanisms, threads and screw rods are arranged in the umbrella-shaped rotary caps, and umbrella-shaped gears, connecting shafts and belt brake worm motors are arranged on the umbrella-shaped rotary caps; and a manual device is further arranged in the control mechanism. A hollow screw rod is adopted to replace a cable machine, a cable wheel, a steel cable, a counterweight block guide rail and a balancing weight block of an existing elevator, so that the structure of the elevator of the lift car is effectively simplified, and the volume of the lift car is expanded; and the belt brake worm motor provided with a remote manual device and arranged on the top of the lift car is adopted to drive the umbrella-shaped rotary heads in the rotary cap type mechanisms to rotate synchronously on the two screw rods to enable the lift carto move up and down, so that the safety hazards caused by the fact that the existing elevator is out of control of a cable crane and the steel cable is worn are effectively avoided, and self-rescue of passengers can be facilitated when black out is happened.

Description

technical field [0001] The application relates to the field of lifters, in particular to a rotary lifter for a car in a small house. Background technique [0002] With the support of the government, small residential buildings with less than eight floors are currently installing car elevators, but all of them use cable elevators. Passengers cannot control the up and down of the car when the power is off, and there are still addictions in safety. Contents of the invention [0003] The present application aims at the above problems and provides a swivel-type lifting device for a car in a small house, which is simple in structure and low in cost. [0004] According to the technical solution of the present application: a swivel-type lifting device for a car in a small house, including a car mechanism, a swivel-type mechanism, and a control mechanism; [0005] Described car mechanism comprises that four well-shaped frame square pipes 1 are arranged on the lift foundation of t...
