Lifter for building construction

Abstract

The invention relates to a lifter for building construction. The lifter for building construction comprises a steel structure consisting of a frame upright beam and a frame cross beam, and a mesh-cage, a guide wheel, a traction wheel and a tractor, a rescue rope, a tension rod, a tension weight, mesh-cage bottom wheels, a traction steel wire rope, a rope hitch plate, a gantry crane, a landing door device, a buffer, a guide rail, a speed limiter steel wire rope and a speed limiter tension wheel arranged in the steel structure, wherein the traction wheel and the tractor are arranged on the top or the bottom of the steel structure consisting of the frame upright beam and the frame cross beam, the guide wheel is arranged on the bottom or the top of the steel structure, and the mesh-cage is provided with four mesh-cage top wheels or mesh-cage bottom wheels. The technical problem to be solved by the invention is to provide the lifter for building construction which has the advantages of improved area utilization rate of hoistways, lowered cost of building facilities, and convenience for installation and debugging.

Description

technical field [0001] The present invention relates to elevators for building construction. Background technique [0002] Construction elevators usually use wire rope friction transmission. The wire rope bypasses the traction sheave, and the two ends are respectively connected to the cargo compartment and the counterweight. The motor drives the traction sheave to lift the cargo compartment. Since the counterweight and the cargo compartment 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 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...

Problems solved by technology

Since the counterweight and the cargo compartment 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 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 narrow shaft, which is cumbersome and difficult to install and debug
