Novel traction method of passenger lift

Abstract

The invention discloses a novel traction method of a passenger lift. The novel traction method of the passenger lift comprises the following steps: a. traction wheels with indexes controlled in the national standard prescribed scope are selected, the anti-abrasion performance and hardness of all traction wheels are kept to be consistent; b. each traction wheel is provided with a cylindrical annular gasket with transverse lines corresponding to a traction rope, and each cylindrical annular gasket is embedded in a corresponding groove wheel; and c. each traction rope is installed on each corresponding traction wheel, the tension of each traction rope is adjusted, and the mutual differential value is controlled within 5%. The novel traction method of the passenger lift prevents abnormal sound in the running process of the lift and prevents a lift cage from shaking, improves the comfort for passengers, prolongs service lives of the traction steel wire ropes, and reduces use cost.

Description

technical field [0001] The invention relates to a method for installing a rope groove of a traction wheel, in particular to a novel traction method for a passenger elevator. Background technique [0002] In the existing elevator installation method, the traction wire rope is usually directly installed on the traction sheave, so that the traction rope is likely to slip sideways in the rope groove, resulting in rapid wear of the traction sheave rope groove. There is also an improved installation method, that is, adding lubricant to the contact surface between the traction rope and the rope groove, or adding wear-resistant ceramic glue on the rope groove as an anti-wear lining, which can play a temporary anti-wear effect. However, the wear-resistant ceramic glue is easy to deform and deforms unevenly, which makes it difficult to control the tension ratio of the traction rope on both sides of the traction sheave. Pulley groove wears out quickly. Among the 6 traction wire ropes...

[0002] In the existing elevator installation method, the traction wire rope is usually directly installed on the traction sheave, so that the traction rope is likely to slip sideways in the rope groove, resulting in rapid wear of the traction sheave rope groove

There is also an improved installation method, that is, adding lubricant to the contact surface between the traction rope and the rope groove, or adding wear-resistant ceramic glue on the rope groove as an anti-wear lining, which can play a temporary anti-wear effect. However, the wear-resistant ceramic glue is easy to deform and deforms unevenly, which makes it difficult to control the tension ratio of the traction rope on both sides of the traction sheave. Rapid wear of pulley rope grooves

Among the 6 traction wire ropes in the worn rope groove, the tension of 1 or 2 wire ropes changes greatly. When the car runs to the top floor, the wire rope is almost unstressed, and the weight of the car is entirely controlled by the remaining wire ropes. The steel wire rope bears, but when the car runs down, the tension of the steel wire rope becomes larger and larger. When running to the middle floor station, the tension of the 6 steel wire ropes is basically the same, but when the car is close to the bottom floor, the tension of the steel wire rope The tension force is obviously much higher than that of the other wire ropes, which bears most of the load of the car, causing the rope end combination spring of the steel wire rope to be severely compressed and collide with the rope head plate to make a "click" sound, and make the car large jitter

Such an installation method causes the elevator to make abnormal noise and the car shakes during operation, which reduces the comfort of the ride. At the same time, it also reduces the service life of the traction wire rope and increases the cost of use.
