Problems solved by technology

This type of joint is suitable for pulling the rope by hand, but it is not strong enough for mechanical pulling
Also, due to the large sleeve, the extension requires a large bend radius and loose anti-jump guards on the rope pulleys, so this method is not suitable for some schemes where the deflection pulleys are small

Embodiment Construction

[0069] figure 1 The hoisting ropes 1aa of the new hoisting rope 1a and the hoisting ropes 1bb of the old hoisting rope 1b are shown opened at their respective ends. The hoisting ropes 1aa and 1bb are unraveled at their ends by substantially the same length as each other, which length is an appropriate distance for this purpose, and every other strand of each rope is cut off corresponding to The length of this distance. The core of the hoisting rope 1aa is also cut off by a length corresponding to this distance. In this case, each hoisting rope according to this example has three remaining strands 2a, 2b each, while the hoisting rope 1bb also has a core 3 left. Before each strand is unraveled and cut off, a suitable number of thin and relatively short sleeves 4, 4a are screwed onto the rope, the diameter of said sleeves being only slightly larger than the outer diameter of the rope, in this case Under normal circumstances, the sleeves 4, 4a are just sleeved on the rope. The...

Abstract

The invention relates to a method and a traction arrangement for changing the hoisting ropes of an elevator comprising at least guide rails (10) along which an elevator car (7) provided with a safety device (7a) runs substantially Walking vertically in the elevator shaft; hoist (8); traction sheave (9); and rope (1b). Each rope (1aa) of the new rope and each rope of the old rope (1b) are fixed by splicing the ropes (1aa and 1bb) together at one of their two ends and by means of each compression sleeve (4, 4a). The joints are reinforced to connect to each other, after which the new rope (1a) is pulled into place by means of the old rope (1b) and the elevator hoist (8).

Description

technical field [0001] The invention relates to a method for replacing the ropes of an elevator comprising at least guide rails along which an elevator car provided with a safety device moves in an elevator shaft in a substantially vertical direction; a hoist; a traction sheave and The old rope system also relates to a traction gear device for replacing elevator ropes in an elevator provided with a hoist and a traction sheave. Background technique [0002] Hoisting ropes used in elevators are subject to wear in use and even break when worn out. For this reason, the safety regulations for elevators require that the hoisting ropes in elevators with hoisting ropes have to be replaced with new hoisting ropes at certain intervals. According to prior art, the replacement of hoisting rope generally is, at first unloads old hoisting rope, then installs new hoisting rope. The disadvantage of this solution is that it is inconvenient and time-consuming to replace the rope in this way...
