Counter-weight-free traction type passenger elevator

Abstract

The invention discloses a counter-weight-free traction type passenger elevator, which relates to an elevator structure, in particular to a counter-weight-free traction type elevator structure. The counter-weight-free traction type passenger elevator comprises a steel structure, a lift car, a guide wheel, a traction wheel, a traction machine, a traction steel wire rope, a gantry crane, a landing door device, a buffer, a guide rail, a speed limiter steel wire rope and a speed limiter tensioning wheel, wherein the steel structure consists of vertical framework beams and transverse framework beams, the lift car, the guide wheel, the traction wheel, the traction machine, the traction steel wire rope, the gantry crane, the landing door device, the buffer, the guide rail, the speed limiter steel wire rope and the speed limiter tensioning wheel are arranged in the steel structure, a pair of guide rails are arranged at the left side and the right side of the inner side of the steel structure, the lift car is arranged in the steel structure and is glidingly matched with the guide rails, the traction steel wire rope is arranged on the lift car, the traction wheel, the traction machine and the guide wheel, the gantry crane and the landing door device are arranged on the lift car, the bottom of the steel structure is provided with a buffer, and one side of the traction steel wire rope is provided with the speed limiter tensioning wheel. The invention provides the counter-weight-free traction type passenger elevator with the advantages that the area utilization rate of hoistways is improved, the matched facility cost of buildings is reduced, and the installation and the debugging are convenient.

Description

technical field [0001] The invention relates to an elevator structure, especially a non-counterweight traction type elevator structure. Background technique [0002] Traction-type passenger elevators have become the leading product in the current passenger elevator market due to their energy-saving, safety, and strong lifting capabilities. Traction elevator is mainly composed of traction machine, guide rail, counterweight device, safety device, signal control system, car and hall door. These parts are respectively installed in the hoistway and machine room of the building. Steel wire rope friction transmission is usually used. The wire rope goes around the traction sheave, and the two ends are respectively connected to the car and the counterweight. The motor drives the traction sheave to lift the car up and down. Since the counterweight and the car of this type of elevator need to be installed in the well at the same time, the utilization rate of the well area is greatly ...

AI Technical Summary

Problems solved by technology

Since the counterweight and the car of this type of elevator need to be installed in the well at the same time, the utilization rate of the well area is greatly reduced; the traction machine is generally installed on the top floor load-bearing ring beam or in a special machine room with high requirements and high cost. The building performance requirements of the wall and the top are high, which increases the cost; at the same time, the components of the elevator are generally installed and debugged in the shaft with a small space, which is cumbersome and difficult to install and debug
