High-speed hoisting system for steel wire ropes on electric push rods

Abstract

The invention relates to a high-speed hoisting system for steel wire ropes on electric push rods, which comprises multiple layers of three-dimensional garages and car-loading lifting devices, wherein each three-dimensional garage is composed of an outer frame structure and an inner frame structure, each layer of the garage is provided with a car-loading lifting device, and the upper and lower adjacent garages are separated by the inner frame structure. Each car-loading lifting device comprises a car-loading plate, four steel wire ropes, a plurality of guide pulleys, a four-fluted pulley block and a holder thereof, an electric push rod and a mounting rack, wherein the four steel wire ropes are used for lifting the car-loading plate, the electric push rod and the four-fluted pulley block are arranged at the top of each layer of the garage, one ends of the steel wire ropes are fixed on the car-loading plate, the other ends of the steel wire ropes are fixed on the mounting rack after passing across the guide pulleys and the four-fluted pulley block, and the electric push rod can drive the four-fluted pulley block to move in the holder. The high-speed hoisting system disclosed by the invention takes the electric push rod as a power driving source, and the actual lifting speed of the car-loading plate is 4 times and 6 time as larger as the actual pushing speed of the electric push rod in case that the four-fluted pulley block carries out winding in a rate of 1:4 and a rate of 1:6. According to the invention, the lifting speed is high and can reach 8-12 m / min; and the high-speed hoisting system is simple in structure and convenient to maintain.

Description

[0001] technical field [0002] The invention belongs to the technical field of mechanical parking equipment (three-dimensional garage), and in particular relates to a high-speed lifting system with electric push rods and wire ropes. [0003] Background technique [0004] With the development of society, people's living standards have been continuously improved, and the popularity of cars has become more and more widespread. The problem of car parking has become more and more prominent. Due to the limited space on the urban ground, building a three-dimensional garage has become a solution to "parking difficulties". an important method. The low-cost, easy-to-maintain lift-and-slide three-dimensional garage is currently the most common model in China, accounting for more than 86% of the entire three-dimensional garage market. [0005] At present, the lifting and lowering driving methods adopted by domestic lifting and traversing three-dimensional garages are mainly divided i...

AI Technical Summary

Problems solved by technology

For the first type of motor acceleration and deceleration machine plus wire rope or chain lifting drive technology, there are two main defects. One is that the noise is too large when the motor is moving, especially when many motors are lifting and lowering at the same time; the other is that The lifting speed is too slow, and the lifting speed of similar products on the market is generally around 5m / min

[0006] And for the driving technology of the second hydraulic pump station plus hydraulic cylinder plus steel wire rope or chain, its main defect has three points, one is because most of this type of structure adopts the so-called " One machine with multiple boards" technology, the whole equipment shares one hydraulic system, once the pumping station or hydraulic system fails, the whole equipment will be paralyzed; the second is because the whole set of hydraulic system involves pumping station, oil pipe, hydraulic valve, pressure relief valve And various oil circuit protection devices, there are many components, and there are many potential failure points, which leads to difficulties in the future maintenance of the equipment, which is currently the biggest problem plaguing all domestic three-dimensional garages that use hydraulic systems.

The last point is pollution. Once oil leakage occurs, it will cause oil accumulation in the entire equipment and on-site, causing serious environmental pollution.
