A belt-wearing hydraulic elevator

Abstract

The invention relates to a threading type hydraulic elevator. The threading type hydraulic elevator comprises an elevator shaft, an elevator car, a hydraulic cylinder, a pulley rope set, a counter-weight set, a prestress mechanism, a hydraulic unit, a hydraulic pipeline, an electronic control center, sensing assemblies and signal lines. The hydraulic cylinder is vertically fixed to the bottom or the side wall of the elevator shaft, and the top of the hydraulic cylinder is connected with the prestress mechanism. The pulley rope set is fixed to the position near the top of the elevator shaft, one end of a steel wire rope of the pulley rope set is connected with the elevator car, and the other end of the steel wire rope is connected with the counter-weight set. The sensing assemblies are connected with the electronic control center through the signal lines. The hydraulic unit is connected with the electronic control center through a control and feedback signal line. The hydraulic cylinder is connected with the hydraulic unit through the hydraulic pipeline. A movement compartment of the hydraulic cylinder is connected with the elevator car. The threading type hydraulic elevator adopts a belt type hydraulic lateral lifting hydraulic cylinder, as an unstability problem of a traditional pressure level does not exists, the stability and the stroke / lifting height of the hydraulic elevator are improved, the structure is compact, the needed shaft space is small, and meanwhile, the personal safety of people taking the elevator is guaranteed.

Description

technical field [0001] The invention relates to a belt-threading hydraulic elevator, relates to hydraulic lifting machinery, and belongs to the technical field of mechanical equipment manufacturing. Background technique [0002] Traditional elevators include traction elevators, hydraulic elevators, rack and pinion elevators, and screw elevators. Elevators used in high-rise buildings basically refer to traction elevators. However, the traction elevator has its defects: first of all, it is safety. A broken wire rope or loosening will cause life-threatening; secondly, the top of the elevator shaft must be designed to bear the total weight of the car, the load and the counterweight device. The layout of the shaft and the horizontal shaft has a large space; at the same time, the noise is large, the ride comfort is poor, and the load is small.

However, the traction elevator has its defects: first of all, it is safety. A broken wire rope or loosening will cause life-threatening; secondly, the top of the elevator shaft must be designed to bear the total weight of the car, the load and the counterweight device. The layout of the shaft and the horizontal shaft has a large space; at the same time, the noise is large, the ride comfort is poor, and the load is small

[0003] Despite all these problems, traction elevators seem to be irreplaceable to a certain extent for high-rise buildings at present; and the large demand for space and safety guarantees of traction elevators also become more and more important with the increase of storey height. It is becoming more and more prominent, how to solve these contradictions has an urgent demand for the rapid growth of elevators used in high-rise buildings and the replacement of tens of thousands of old elevators waiting to be updated

[0004] The hydraulic elevator can provide a large lifting force because of its good safety, low noise and high reliability. At the same time, it is not necessary to set up a machine room on the roof, which reduces the vertical size of the well and can effectively use the building space. It seems to be able to make up for all the defects of traction elevators, but the current design of hydraulic elevators makes all its advantages not worth the limitation of its lifting stroke. limit its scope of application

[0005] After careful analysis, it can be found that the defects of hydraulic elevators are actually the defects of hydraulic cylinders: slow lifting speed (below 1m / s), high power consumption, and high cost. For short strokes and heavy loads

Therefore, the design of hydraulic elevators relying on traditional hydraulic cylinders can never catch up with the advantages of traction elevators in terms of lifting height. If you want to change this state and increase the lifting height of hydraulic elevators, you must replace the traditional hydraulic cylinders

[0006] The patent with the notification number CN105041763A discloses a "belt-type hydraulic lateral lifting device", which realizes hydraulic sealing and pushes the piston to lift and output movement through the lateral slit-closed structure. Since there is no traditional hydraulic rod , it can realize the stable full-stroke work of the hydraulic cylinder (traditional hydraulic cylinders work for half-stroke, and the outstretched pressure rod has stability problems), which greatly improves the working stroke and stability of the hydraulic cylinder, and also increases the hydraulic pressure. Elevator travel requirements provide new insights
