Equation rack-and-pinion construction elevator

Abstract

An equational gear rack elevator involving of a construction lift provides an equational gear rack construction elevator. It has frame, rack, base frame, top beams, two top wheels, suspension cage, driven mainframe, driven gears, suspension cage pulley, counterpoise and balancing steel wires. The frame comprising of bulk components from bottom to top is installed on the base frame, the top beams are on the top of frame, the top wheels are on the top beams and the counterpoise is in the frame. And motor and pulleys are installed on the suspension cage; gears are installed on the mainframe and mesh with the rack; one end of steel wires is linked with the counterpoise and the other is linked with the suspension cage through the top wheels. The frame can be installed the required height one-time in the condition of not having add-walls and can be installed and operation at the start of construction. It reduces the overturning weight moment greatly, reduces the power consumption and avoids the danger of suspension cage cross beyond the top of guide rail, the equipment is more reasonable and safe. The construction lift is easy to installing, and the occupied storage space is small, decreases the cost of manufacture and install greatly.

Description

technical field [0001] The invention relates to a construction elevator, in particular to an equation rack-and-pinion construction elevator that can meet the requirements of installation and production in the early stage of construction, save energy consumption, and have a higher safety factor. Background technique [0002] Construction elevators are important equipment in the construction industry. The existing rack and pinion construction elevators are mainly composed of frame body, rack, base, sky wheel, cage, accompanying cable, driving host, driving gear, cage pulley, counterweight, balance Composed of steel wire rope and attached wall frame. The frame bodies are welded into integral standard sections, and stacked on the base in turn. The installation condition of the stacked height of the frame is to use the cage to climb up and carry the standard section for lifting. Since the sky wheel with the balance weight must be set at the highest point of the frame, before the...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to address the following shortcomings of the existing rack and pinion construction elevators: 1. It cannot be erected before the building is built high, and cannot meet the needs of early construction; For heavy balance, the cage and pulleys must overcome all the overturning moments caused by the self-weight of the cage and the gravity of the load; 3. When the installation frame is high, it is easy to cause the danger of the cage going over the upper end of the guide rail; 4. The counterweight is a single piece, and the installation Difficult, the balance coefficient is limited, and the power and energy consumption is large; 5. The cost of manufacturing and installation is high, and it takes up a lot of stacking space. A kind of equation rack and pinion construction elevator is provided
