Problems solved by technology

[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,

Example Embodiment

[0021] Example 1. A new type of traction method for passenger elevators. Installing the traction rope on the traction sheave to lift the elevator includes the following steps:

[0022] a. Select traction wheels whose various indicators are controlled within the scope of the national standard, and ensure that the wear resistance and hardness of each traction wheel are consistent;

[0023] b. Install a cylindrical ring liner with a transverse pattern corresponding to the traction rope strands on each traction wheel, insert the cylindrical ring liner into the corresponding sheave wheel, the cylindrical ring liner has a radial thickness of 3cm , The depth between the horizontal lines is 20% of the thickness of the cylindrical ring gasket;

[0024] c. Install each traction rope on the corresponding traction sheave, and adjust the tension of each traction rope to control the mutual difference within 4%;

[0025] In the step b, the material of the cylindrical ring liner is a polyurethane com...

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...
