Description

Pull-out evacuation ladder hoisting device {winch for ladders device to emergency}

The present invention relates to a lifting ladder hoisting device, and more particularly, a drum for winding or unwinding a rope or a rope, a towing wire for towing, a latch wheel for restraining rotation of the drum, and a latch wheel. And a latch lever for releasing and releasing, a friction piece for slowing down the rotation of the drum, and a casing composed of a first cover and a second cover for enclosing the shafts provided at both ends of the drum. When emergency emergencies such as these can be very quickly and safely escape to the lower floor, it relates to a down-lift evacuation ladder hoisting device that can minimize human and physical damage.

In the event of fire or other emergencies in high-rise buildings, evacuation is virtually inevitable, causing many casualties.

Therefore, the law stipulates that mandatory escaping means must be provided for escaping in case of misconduct.

As a representative means of emergency escape, stiffeners are widely adopted, but since it descends along the outer wall of the building depending on the wire rope, it is very difficult and dangerous for the general public to use, and the escape speed is high. It is so slow that it is rarely used, which implies a huge problem in effectiveness.

On the other hand, high-rise buildings, including apartments, are equipped with fire doors that automatically block passages near the place of fire to suppress their spread in case of fire. Evacuation is virtually impossible and can only be isolated in fire.

However, unlike other high-rise buildings such as hotels and office buildings, ordinary residential apartments do not have emergency escape means such as stubborns, so they cannot escape, and most of them rely on escapes for firefighting ladders or rescue helicopters. In other words, high ladders are limited in height and rescue helicopters are inaccessible to fire-dwelling areas.

In particular, in recent years, high-rise apartments and buildings with several tens of floors have appeared one after another, and thus, the above-mentioned problems of evacuation and the consequences of human injury are increasing.

Korean Patent Nos. 0529859 and 0481693, Korean Patent Publication No. 10-2009-0060033, and the like have been proposed, for example, to provide an evacuation ladder on the balcony railing to evacuate to the lower floor through the balcony of the apartment.

A pair of towing wires connected to the lower end of the innermost ladder unit through a coupling guide, a ratchet wheel fixed concentrically with the winding drum, and one end of the ratchet wheel elastically engaged, so that the winding direction of the winding drum rotates. A latch lever for permitting only release and release of the ratchet wheel by external force, and a separating handle mounted inside the body of the housing and selectively coupled to a connecting boss of the winding drum to rotate the winding drum in a winding direction. The invention relates to a high-rise building evacuation device, but the winding drum is interlocked through a planetary gear device to wind or unwind the traction wire to reduce or wound It is one configuration to be able to take.

The planetary gear device is configured to decelerate or wind the drum by an internal gear formed at the inner circumference of the casing, a sun gear formed at one end of the latch wheel, and three planetary gears. It is difficult to maintain and repair due to its complicated structure, and the increase of manufacturing cost and maintenance cost increases with the increase of the number of parts, and it is difficult to operate during emergency evacuation due to rust if not oiled and managed by periodic maintenance. It is pointed out that the problem is that people cannot be damaged due to deterioration and speed and safety.

Accordingly, the present invention is to solve the problems as described above, the object of the present invention is to install on the floor of high-rise buildings and structures to the hoisting device of the evacuation device that can escape to the lower floor during a disaster as a simple structure evacuation The purpose of the winch is to operate the winch quickly and safely in preparation for the correct position so that the deceleration can be operated quickly and accurately.

Another object of the present invention is to reduce the speed of the conventional winch by using an internal gear and a planetary gear inside the casing, but to exclude this and operate the friction piece on the simple winch structure to maintain the braking performance at any time to maintain the speed and safety.
