Embodiment Construction

[0030] Embodiments of the elevator equipment according to the present invention will be described below with reference to the drawings.

[0031] Such as figure 1 and figure 2 As shown, the elevator equipment has: a guide rail 2 vertically arranged in the elevator passage 1; an elevator car 4, which is suspended by a sling 3, and lifts in the elevator passage 1 under the guidance of the guide rail 2; a buffer 5, When the elevator car 4 is abnormal and the lifting position exceeds the specified position, the buffer buffers the collision of the elevator car 4; the emergency braking device 6 is arranged on the outside of the elevator car 4, Brake the elevator car 4 when an abnormality occurs;

[0032] Such as image 3 As shown, the above-mentioned emergency braking device 6 has: a frame body 6a fixed on the elevator car 4; wedge-shaped brake parts 6b, which are arranged in pairs across the guide rail 2; In case of abnormality, lift the brake piece 6b so that the brake piece 6...

Abstract

An elevator device which can have a buffer equipped without setting a special installation mechanism has obvious effects in shortening the depth and size of a pit. The elevator device comprises an elevator car (4) elevating inside an elevation channel (1) and comprising a buffer (5) and an emergence brake device (6). The buffer comprises a cylinder body and a piston inserted inside the cylinder body. When a fault occurs in the elevator car and an elevation position runs beyond a set position, the buffer is then applied for buffering the collision received by the elevator car. The emergence brake device which is equipped on the outer side of the elevator car comprises a brake member capable of performing sliding contact with a guide rail vertically equipped inside the elevation channel and is applied for braking the elevator car when a fault occurs. The buffer is equipped on the emergency brake device. Meanwhile, the buffer is equipped in a way to be projecting from the lower end of the elevator car. The projecting size of the buffer is equal to a required size gap between the elevator car and a pit floorboard (7a) when the buffer runs for a cushioning stroke and then stops.

Description

technical field [0001] The present invention relates to an elevator device, which buffers the collision of the lifting body through a buffer when the lifting position exceeds a predetermined position due to an abnormality in the lifting body. Background technique [0002] Elevator equipment is known that buffers the collision of a lifting body (such as an elevator car) whose lifting position exceeds a predetermined position due to an abnormality by using a buffer. In the elevator car, in order to shorten the The depth dimension of the pit is that a buffer is provided on the outer side of the elevator car. The base of the buffer is arranged above the lower surface of the elevator car and is set in a drooping state. When the elevator car When an abnormal descent occurs, the shock absorber is pressed by the bottom surface of the hoistway to operate (for example, refer to Patent Document 1). [0003] Patent Document 1 Japanese Patent Laid-Open No. 2001-146370 (paragraph numbers...
