Embodiment Construction

[0052] Hereinafter, an emergency stop device for an elevator according to an embodiment of the present invention will be described with reference to the drawings.

[0053] figure 1 It is a perspective view showing the outline of an elevator car with an emergency stop device. A sling 12 is installed on the upper part of an elevator car 11 for passengers. unillustrated drive system connections. exist figure 1 In , for the sake of convenience, the illustration of the elevator door opening and closing mechanism and the detailed structure of the external frame, etc. are omitted.

[0054]On both sides of the hoistway for the elevator car 11 to move up and down, there are guide rails 13 that guide the elevator car 11 to move up and down and cooperate with the brakes to prevent the elevator car 11 from accidentally descending. The guide rails 13 are arranged on opposite sides of the elevator car 11 in pairs.

[0055] A pair of emergency stop devices 14 are provided corresponding t...

Abstract

To prevent temperature rise of friction components and enable high-speed and large-capacity elevators to generate a stable braking force, the invention provides an emergency stop device for the elevators. To stop an elevator car (11), a brake component (15) is disposed in a guide rail (13) in a lifting channel through pressing and slides on the guide rail (13) for generating the braking force. The brake component (15) for the emergency stop device for the elevators comprises a plurality of friction components (51, 52) and a support body (21); the braking force is generated between the friction components (51, 52) and the guide rail; the support body (21) is used for supporting the friction components (51, 52) which comprise a first friction component (51) disposed at the front end of the elevator car (11) in the descending direction and second friction components (52) disposed on the subsequent side of the first friction component (51), the thermal conductivity of the first friction component (51) configured to be greater than the thermal conductivity of the second friction components (52).

Description

technical field [0001] The present invention relates to a braking part of an emergency stop device for an elevator, an emergency stop device for an elevator and an elevator, in particular to a braking device for an emergency stop device for an elevator that can obtain stable braking force in a high-speed or large-capacity elevator Moving parts, emergency stop devices for elevators and elevators. Background technique [0002] Generally speaking, an emergency stop device is installed on the elevator car as a safety device. When an abnormality occurs in the elevator and the elevator car descends at a speed above a certain speed, the emergency stop device will stop the elevator car at a predetermined deceleration. stop. [0003] When the descending speed of the elevator car reaches a predetermined speed or more, the emergency stop device clamps the guide rail arranged on the wall of the elevator passage through which the elevator car passes through the brake member provided wit...
