Terminating set for elevator device

Abstract

The invention discloses a terminating set for an elevator device. The terminating set comprises a socket with a support point, wherein a wedge is arranged between two supporting pieces and provided with two first profile surfaces which form certain included angles with the center of the wedge and are arranged oppositely; the two supporting pieces are provided with second profile surfaces corresponding to the first profile surfaces; a bearing element for elevating the elevator device is clamped between the first profile surface and the second profile surface; the wedge and the supporting pieces are at least partially positioned inside the socket; each supporting piece is provided with at least one contact profile; the contact profile is positioned between the supporting piece and the socket and allows the two supporting pieces to rotate in the socket; the wedge is driven to rotate by the two supporting pieces; and when external force is applied to the bearing element, the two supporting pieces and the wedge rotate to a position at which the bearing element and the support point of the socket are basically on the same straight line. The terminating set has a simple and reliable structure, balances the pressure on the bearing element of the elevator device and prolongs the service life of the bearing element.

Description

technical field [0001] The invention relates to a termination device for an elevator installation. Background technique [0002] Termination device for conventional elevator installations consisting of a cast socket and wedge around which the load-bearing element of the elevator assembly is inserted into the socket; clamping is produced by tensioning of the load-bearing element and engagement between the wedge and socket force. The disadvantage of this is that since both the socket and the wedge are cast, the angle formed inside the socket will not be completely consistent with the angle of the wedge, so that the load-bearing element cannot be well fixed in the socket. Simultaneously, the bearing element is subjected to uneven pressure from the socket and the wedge, and some parts of the bearing element located in the socket will be subjected to very large pressure. In the worst case, the load-bearing element will break at this position, resulting in a large loss of streng...

Problems solved by technology

The disadvantage of this is that since both the socket and the wedge are cast, the angle formed inside the socket will not be completely consistent with the angle of the wedge, so that the load-bearing element cannot be well fixed in the socket. At the same time, the bearing element is under uneven pressure from the socket and the wedge, and some parts of the bearing element located in the socket will be subjected to very large pressure

This will result in non-uniform compression of the load-carrying element, which may result in very high localized compressive stresses on the load-bearing element, crushing or creep of the elastic wrapping material, and failure of the termination
