Description

Car is from tensioning from elevator system that climbs

Technical Field

The utility model belongs to the technical field of the elevator technique and specifically relates to a car is from elevator system that climbs certainly of tensioning.

Background

The conventional elevator adopts a traction motor to pull and lift a car, the traction motor is usually arranged in a machine room at the top of a well or in the space at the top of the well, a suspension rope bypasses a motor traction sheave, one end of the suspension rope is connected with the car, the other end of the suspension rope is connected with a balance weight, and the motor drives the traction sheave to rotate and lifts the car to move up and down in the well by means of friction between the suspension rope and the traction sheave.

In the chinese patent document, "a rope-lifted elevator system", whose publication number is CN108861957A, a novel rope-lifted elevator system is disclosed, which is different from the above-mentioned conventional system arrangement, and realizes the self-lifting of the elevator car by the driving motor and the double sheave installed on the elevator car, and provides several possible driving system arrangements, but all of them have at least the following two design defects, resulting in difficulty in practical implementation of the scheme. The first defect is that a large tensioning block needs to be arranged at the bottom of the well, so that the tensioning block does not shake up, down, left and right, and meanwhile, a limiting and guiding device for avoiding the tensioning block from shaking is required to be arranged, so that the cost is greatly increased, and the maintenance space of the pit is influenced. Secondly, the Euler's theorem, which is a common physical knowledge, ensures that the suspension rope is on the traction sheave to ensure sufficient traction forceNo slip, need to satisfy T1/T2<=e ^fa Wherein T1 is the tension of the stressed end of the traction double-sheave connected with the lift car, T2 is the tension of the stressed end of the traction double-sheave connected with the tension block, f is the friction coefficient between the flexible suspension rope and the traction sheave groove, and a is the total wrap angle of the flexible suspension rope around the two traction sheaves. According to the patent scheme, assuming that a traction wrap angle a =210 degrees, a friction coefficient f =0.35, a tensioning block mass W, a car self-weight P =800kg and a rated load Q =400kg, e is provided ^fa =3.61，T1/T2=(W+P+Q)/(W)=1+(P+Q)/W=1+1200/W<= e ^fa =3.61，W>=460kg. However, considering that the friction coefficient of the actual friction contact surface may be reduced due to the factors of wear, oil contamination, etc., from the safety point of view, the possible adverse conditions should be considered when designing the tension, for example, when designing with f =0.2, e is ^fa =2.08，T1/T2=(W+P+Q)/(W)=1+(P+Q)/W=1+1200/W<= e ^fa =2.08，W>Therefore, the weight of the tensioning block must be kept large in design redundancy to ensure that the traction contact surface does not have the safety risks of slipping and the like due to abrasion or oil stain influence, which further increases the cost due to the increase of the weight of the tensioning block and the strength of the steel wire rope.
