Terminating set used for elevator device

Abstract

The invention discloses a terminating set used for an elevator device, which comprises a socket, a wedge block and two supporting pieces, wherein the wedge block is arranged between the two supporting pieces; the wedge block is provided with two first outline surfaces which are arranged with respect to the center of the wedge block at a certain angle; the two supporting pieces are provided with second outline surfaces corresponding to the first outline surfaces; a bearing element lifting the elevator device is held between the first outline surfaces and the second outline surfaces; the wedge block and at least partial supporting pieces are positioned at the inner part of the socket; each supporting piece is provided with at least one contacting outline which is positioned between the supporting pieces and the socket, the contacting outline leads the two supporting pieces to be capable of rotating in the socket, and the rotating centers of the two supporting pieces are same. The terminating set has simple and reliable structure, uniform pressure of the bearing element of the elevator device, and long 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
