Construction elevator

Abstract

The invention discloses a construction elevator. The construction elevator comprises a modular suspension cage, a trolley frame, standard sections, a cable drum, a cable and an electric control system, wherein the multiple standard sections are sequentially connected up and down to form a guide rail frame; the trolley frame and the modular suspension cage are installed on the guide rail frame; thetrolley frame is arranged above the modular suspension cage; the cable drum is arranged on a foundation pit ground under the modular suspension cage; the cable is wound on the cable drum; one end ofthe cable is upwards fixed to the center of a bottom plate of the modular suspension cage and is connected into the electric control system; the modular suspension cage comprises a main frame, a portal and lengthening modules; the main frame is of a tank structure with openings on two sides; one or more lengthening modules are connected to two opening sides of the main frame; each lengthening module is of a tank structure with openings on two sides; and the outermost lengthening module is connected with the portal. The arrangement space of the suspension cage can be enlarged, the constructionelevator can adapt to hoistways with different sizes, and the suspension cage can be disassembled into pieces.

Description

technical field [0001] The invention belongs to the field of construction elevators, in particular to a construction elevator. Background technique [0002] Construction elevators are commonly used in building construction and are responsible for the vertical transportation of people and goods. Existing construction hoists are generally installed outside buildings or in elevator shafts. When installed in the elevator shaft, due to the small cross-sectional area of ​​the shaft and various sizes and specifications of the shaft, in order to maximize the use of the shaft space, the cage is generally customized according to the size of the shaft, resulting in various sizes of the cage, and the customized cage cannot be used in Different wells lead to great waste. [0003] The cross-sectional size of the standard section of the existing elevator is generally 650×650mm or 800×800mm, and installing it in the hoistway will occupy the layout space of the cage, resulting in a further...

AI Technical Summary

Problems solved by technology

As the outside of the cage is placed against the wall, there is no space to install the cable arm and cable drum, so the elevator can only be powered by cable pulley or trolley line

[0005] The opening of the elevator hoistway door is small, and the conventional hoisting cage cannot enter and exit the hoistway door. The installation and disassembly of the elevator is very troublesome. In some cases, cutting and disassembly are even required
