Problems solved by technology

Of these, only the document EP1097101B1 provides tensioning of the traction device, but it is implemented by a combination of springs and counterweights, which is large in size and does not allow constant force tensioning
However, in all solutions there is also only one large counterweight, the disadvantages of which have been explained earlier

Embodiment Construction

[0020] figure 1 with 2 A fixed arrangement of the traction device 7 of an elevator according to the invention is shown. The tensioning arrangement comprises at least one or more fixing means 1, 1a, 1b fixed from its frame part 1i to the bottom of the elevator car 11 or directly to the elevator car 11, Either in connection with the car hanger of the car, the fastening device is configured such that a tensioning of as constant a force as possible is achieved in the traction device 7 , 7 a , 7 b.

[0021] The fixing device 1, 1a, 1b comprises at least the aforementioned frame portion 1i, a roller 1c mounted on a shaft 1f of a bearing so as to rotate freely, an adjusting device 1d rotating together with the roller 1c, and a tensioning device 1g, which The free end of is tensioned into its proper position in the second end of the frame part 1i by means of a spring 1j. The frame portion 1i is, for example, a metal plate bent into a U shape as seen from above, which includes a ba...

Abstract

The object of the invention is a tensioning arrangement for a traction means of an elevator, which arrangement comprises at least an elevator car configured to move up and down in an elevator hoistway and at least one or more compensating weights, which are for their part connected to support the elevator car by the aid of their own support means, such as by the aid of ropes or belts and also of diverting pulleys, and a hoisting machine provided with at least one traction sheave or corresponding, and also at least one traction means (7) such as a belt, rope or chain, which is configured to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weights. The traction means (7) is fixed from at least one of its ends to a fixing means (1) providing an essentially constant tensioning force.

Description

technical field [0001] The object of the invention is a tensioning arrangement for a traction device of an elevator as defined in the preamble of claim 1 . [0002] The configuration according to the invention, thanks to its solution with a traction device separate from the suspension ropes of the elevator car, is very suitable for use in elevators for low and medium-rise buildings and even very high-rise buildings, where one problem is that when With the hoist of the elevator above, the installation of the machine and the surrounding structure is awkward, expensive and even dangerous. Additionally, high speed elevators in high rise buildings require large fuses and there are often many elevators in one or more elevator banks. For this reason, the cables required for the elevator hoists are also expensive and in high-rise buildings this is even more pronounced because the cables from the switchboard below to the hoists above are longer. Long cables cause power loss and vario...
