Embodiment Construction

[0056] figure 1 An embodiment of an elevator rope terminal structure A including the elevator rope terminal apparatus 1 is illustrated. figure 2 Illustrated figure 1 The top view of the rope terminal structure A.

[0057] The cord terminal structure A includes a cord end E and a cord terminal body B having a cavity C for accommodating the cord end E inside. The cord terminal body B includes an aperture O through which one or more cord ends E pass into the cavity C. As shown in FIG.

[0058] The cord terminal body B is a metal block surrounding the one or more cavities C. Its weight is more than 200 kg, whereby it provides thermal storage around the cavity or cavities for delaying heat transfer from the outside to the rope ends E contained in the cavity or cavities C it surrounds piece. The high thermal mass of the cord terminal body B achieved with the weight of the cord terminal body B arranged around the cavity C provides that it is able to absorb large amounts of heat...

Abstract

The invention relates to a rope terminal device (1) for fixing rope ends (E) of ropes (R) of an elevator, comprising a rope terminal body (B) comprising one or more cavities (C) for accommodating one or more rope ends (E); one or more fixing members (2,3) for fixing the one or more rope ends (E) immovably into the one or more cavities (C); wherein the rope terminal body (B) is a metallic block surrounding said one or more cavities (C), and weighs more than 200 kg, the rope terminal body (B) providing thermal mass around the one or more rope cavities (C) for delaying heat transfer from the exterior to the rope ends (E) contained in the one or more cavities (C). The invention relates to a rope terminal arrangement (A) and an elevator implementing said rope terminal device (1).

Description

technical field [0001] The present invention relates to a rope terminal device of an elevator, a rope terminal structure of an elevator and an elevator. The elevator is preferably an elevator for vertical transport of passengers and / or goods. Background technique [0002] In an elevator, one or more ropes are used as means for suspending the load to be lifted. Each rope end needs to be fixed to an anchor, usually either the load to be lifted or the stationary structure (depending on the type of suspension chosen for the elevator). The rope ends may be fixed directly to a load such as a car or counterweight, which is the case when the car and counterweight are suspended in a 1:1 ratio. Alternatively, the rope ends may be fixed to the stationary structure of the building, which is the case when the car and counterweight are suspended, say in a 2:1 ratio. [0003] The ropes of elevator ropes are usually ribbon-shaped or round in cross-section. Each elevator rope typically i...
