Problems solved by technology

[0012] But the problem is that in order to obtain the necessary force and stroke on the traction at a small angle, it is effective to increase the distance between the position of the traction inner cable and the center of rotation of the rod, but the overall length of the rod must be lengthened
As a result, the brake release device must be enlarged to increase the storage space, which is not ideal for design.
[0013] In addition, in or

Example Embodiment

[0031] Hereinafter, embodiments of the elevator hoist brake release device according to the present invention will be described with reference to the accompanying drawings.

[0032] First, refer to Image 6 , to describe the ordinary elevator. Image 6 It is a schematic diagram showing an example of an elevator.

[0033] The elevator 100 includes a car 104 vertically movably arranged in a building hoistway 101 and an elevator hoist (also referred to as a "hoist") 102 arranged above the hoistway 101 . One side of the steel cable 103 hanging down from the winch 102 is wound on the driven pulley 105 provided on the lower side of the car 104 , and the end of the steel cable 103 is supported near the upper end of the hoistway 101 .

[0034] In addition, the other side of the steel cable 103 hanging from the winch 102 is wound on the pulley 107 assembled on the top of the counterweight 106 , and the end of the steel cable 103 is supported near the upper end of the hoistway 101 .

Abstract

A brake-releasing device has an outer tube (11) and an inner wire (12) that are extended between a brake (102a) for a hoist (102) and a holder box (20) that is installed in the vicinity of a landing area (108). An operation lever (40) connected to the inner wire (12) is swingably provided at a frame (30) in the holder box (20). The outer tube (11) is connected to the frame (30) by an outer tube-fixing shaft (35). The inner wire (12) is connected at its fore-end portion (12a) to the operation lever (40) by an inner wire-connecting shaft (46).
