Garage traction lifting system
Technical Field
The invention relates to the technical field of garage equipment, in particular to a garage traction lifting system.
Background
With the rapid development of social economy, the living standard of people is continuously improved, the number of automobiles is increased day by day, the supply of parking spaces in urban areas is seriously insufficient, the traditional parking lot is slowly developed, and the resource waste phenomenon is serious.
The traditional garage lifting system mainly has two modes of chain lifting and steel wire rope lifting. The chain lifting is relatively low in comprehensive cost and is applied more, but the safety problem of the chain lifting is relatively outstanding, so that on one hand, the structure of the chain is complex, and the maintenance is relatively complicated; on the other hand, the chain consists of a plurality of pin shafts and chain plates, so that slight fatigue damage is difficult to find and detect, but vehicle falling accidents can be caused as long as any one of the pin shafts and the chain plates is broken, and the safety performance of the garage adopting the chain lifting mode is difficult to guarantee. The fatigue and the breakage of the steel wire rope are easy to find, the steel wire rope is broken slightly in the using process, and the accident of sudden breakage is avoided, so that the safety is high. The steel wire rope hoisting has the drum forced traction mode and the traction sheave friction traction mode, and the drum forced traction mode is forbidden in the elevator industry due to a plurality of unsafe factors, so the traction mode is the safest hoisting mode. The traction mode is divided into a 1:1 mode adopting direct hoisting and a 2: adopting movable pulley hoisting on a steel wire rope hoisting point: mode 1. The traction type lifting force depends on the friction force between a steel wire rope and a traction sheave, and for the same load lifting, the weight ratio of 2: the 1 mode is 50% less than the 1:1 mode, so 2: the 1-type hoisting machine is much lower in cost than the 1: 1-type hoisting machine, and the possibility of slippage between the traction sheave and the wire rope during hoisting is much lower, so that it is preferable to use a 2: 1 traction mode. But 2: 1, a movable pulley with the diameter not less than 20 times of the diameter of the steel wire rope is required to be arranged at a steel wire rope lifting point, so that the internal space of the garage is occupied and wasted.
