Embodiment Construction

[0025] Hereinafter, an emergency brake device for an elevator according to an embodiment of the present invention will be described with reference to the drawings.

[0026] Elevator has: a pair of guide rails 1, and it is vertically arranged in the hoistway that is formed in the building; The main sling 3 connected; the balance weight 4 connected with the other end of the main sling 3; Drive the elevator car 2 in the up and down direction; the governor 6, which is supported on the building, is used to detect the lifting speed of the elevator car 2; the governor rope 7, which is wound on the governor 6, Moving synchronously with the elevator car 2; lifting mechanism 8, which is supported by the elevator car 2 and connected to the governor rope 7; The emergency braking device 10 is fixed on the lower end of the elevator car 2 and is arranged opposite to each guide rail 1 . Furthermore, the emergency braking device 10 can also be fastened to the upper end of the elevator car 2 ...

Abstract

In order to maintain uniform pressing force of a brake shoe, multiple plate springs are superposed in the up and down direction. The pressing force applied to the brake shoe is maintained uniform by adjusting the pressing force of each plate spring with adjusting plates and adjusting screws. Because multiple plate springs and adjusting plates and adjusting screws which correspond to the plate springs, problems of complex structure and increased amount of components are provided. The invention provides an emergency braking device used for an elevator and an elevator. The brake shoe is configured in manner in which a contact plate is mounted on the back surface part of the brake shoe, wherein the back surface part is opposite to a guiding member. A pressure adjusting plate is detachably disposed between the back surface part and the contact plate. Therefore, the pressing force borne by brake shoe from the guiding member can be adjusted. The pressure adjusting plate is disposed between brake shoe and the contact plate, and the displacement of the elastic body of the part equipped with the press adjusting plate of the contact plate is adjusted. therefore, the pressing force distribution of the brake shoe in the up and down direction can be adjusted.

Description

technical field [0001] The present invention relates to an elevator that uses the elevator car to transport passengers and goods between the upper and lower floors of a building, and more particularly relates to an elevator car that performs emergency braking when the elevator car descends at a speed exceeding a specified speed. An emergency braking device for a moving elevator and an elevator with the emergency braking device for an elevator. Background technique [0002] In a general elevator, as a safety device, an emergency braking device is installed on the elevator car. The car stops at a specified deceleration. [0003] In an emergency when the elevator car reaches a predetermined descending speed, the brake shoe provided with at least a pair of trapezoidal friction materials is clamped by the elastic body on the guide rail arranged on the wall of the elevator passage for the elevator car to ascend and descend, Using the wedge effect of the brake shoe, the friction ...
