Building lifter with tractor at bottom

Abstract

The invention discloses a building lifter with a tractor at the bottom, relating to lifter structures. The building lifter with the tractor at the bottom comprises an lifter outer frame structure consisting of a frame upright beam and a frame cross beam, wherein a cargo car body is arranged in the lifter outer frame structure; a guide wheel, a rescue rope, bottom wheels, a traction steel wire rope, a gantry crane, and a landing door device are arranged on the cargo car body; buffers are arranged at the bottom of the lifter outer frame; a guide rail, a speed limiter steel wire rope and a speed limiter tension wheel are arranged in the lifter outer frame; a traction wheel and a tractor are arranged at the bottom of the lifter outer frame structure consisting of the frame upright beam and the frame cross beam; the guide wheel is arranged on the top of the steel structure, and the cargo car body is provided with four bottom wheels. The building lifter with the tractor at the bottom, provided by the invention, has the advantages of improved utilization rate of building facilities, lowered cost of building facilities, and convenience for installation and debugging.

Description

technical field [0001] The present invention relates to lift structures. Background technique [0002] Construction elevators have become the leading products in the current construction elevator market due to their energy saving, safety, and strong lifting capabilities. The elevator is mainly composed of traction machine, guide rail, counterweight device, safety device, signal control system, cargo compartment and so on. These parts are installed separately in the building facilities. Steel wire rope friction transmission is usually used. 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 cargo compartment of the 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-bearin...

AI Technical Summary

Problems solved by technology

Since the counterweight and cargo compartment of the 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, which has great impact on the construction facility wall and The performance requirements of the building on 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
