Description

Descending Machine {A Descending Device for Escape}

The present invention relates to a slumber, and more particularly, to a slumber configured to evacuate safely and easily in an emergency such as when a fire breaks out in a building.

As a device for allowing the evacuator to descend at a safe speed in an emergency such as a building fire, two types of use are known.

First, as shown in FIG. 1, after the ascending machine 100 is fixedly installed in a building, the rope 30 is moved and lowered, so that one end of the rope 30 is lowered to the ground. It is a way of hanging down to the other end. In such a case, one person first lands completely on the ground, then the back person descends.

Secondly, a plurality of assembling machine 100 is provided in advance in the building, the evacuees wear the assembling machine 100 directly in an emergency, and as shown in FIG. It's coming down. In this case, as the rope 30 is fixed and the descender 100 itself moves, evacuators can descend continuously, which is advantageous in time.

On the other hand, most of the mild steels currently used in the above-described method uses a centrifugal friction brake. That is, once the speed reaches a certain value, the winshoe force of the brake shoe overcomes the spring force and expands to contact the brake drum, whereby the frictional force between each other makes the structure rigid. Therefore, in this case, the descending speed must be greatly changed periodically, and it was very difficult for the elderly and the injured to hang down.

In addition, since friction is used, not only wear of the brake shoes and drums is inevitable depending on the number of times of use, but it is also cumbersome to accurately determine the degree of wear and determine the replacement time.

In addition, high temperature is easily formed at the contact portion of the steelwork by frictional heat during the fall, and thus the strength of the peripheral device is also lowered, and thus it is difficult to secure perfect safety.

The present invention is devised to solve the above problems, the object of the present invention is to provide a sturdy steel that can be used at a constant speed, semi-permanent without using friction.

In order to achieve the above object, the steel bar according to the present invention,

A frame formed at both left and right sides with a space in the middle;

A pulley and a drive gear installed side by side on a first rotation shaft installed across both left and right sides of the frame and freely rotating about the first rotation shaft;

A driven gear freely rotatable about a second rotational shaft provided on one side of the frame while being engaged with the drive gear;

It characterized in that it comprises a pressure cylinder device having a rod portion rotatably supported at one point on the side of the driven gear, and a cylinder portion rotatably supported on the frame or the first rotating shaft.

When the cylinder portion is supported by the frame, it is preferable that the cylinder portion of the pressure cylinder device be freely rotated with respect to the rod provided over both the left and right sides of the frame.

The frame is preferably covered with a pulley, a drive gear, a driven gear, and a pressure cylinder device, and has a built-in case in which an opening is formed in a portion through which the rope passes.

Here, it is preferable that the inner case is rotatably supported and additionally provided with a reinforcing gear engaged with the driven gear.

Further, it is preferable that a first magnet is fixedly attached to the side surface of the pulley, and a second magnet in sliding contact with the first magnet is fixedly attached to the inner surface of the built-in case, thereby adding a stiffening effect.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

3 and 4 shows an embodiment of the steel bar according to the present invention.

First, there should be a frame 1 for supporting the main components of the present invention. The frame 1 is provided on each of the left and right sides, and a space including the components is formed therebetween. The frame 1 needs to have sufficient strength to support the weight (dynamic weight) of the evacuator.

Then, the first rotation shaft 2 traverses the left and right sides of the frame 1 so that rotation is freely supported.

In addition, the pulley 3 and the drive gear 4 are fixedly installed side by side in a state where they are concentric on the first rotation shaft 2. The pulley 3 and the drive gear 4 may be separated from each other or may be fixed.

Here, the first rotation shaft 2 may be fixed to the frame 1, and the pulley 3 and the driving gear 4 may be installed through a bearing (not shown).

The pulley 3 is a part for guiding a rope (not shown), and a relatively deep groove 31 is formed at the part where the rope is in contact. The groove 31 is formed with a protrusion (not shown) periodically to prevent the slip of the rope. The configuration of such pulley 3 will be conventional.

The drive gear 4 may be a spur gear, a helical gear, or the like, but an economic aspect should be considered.

On the other hand, the driven gear 6 is meshed with the drive gear 4. To this end, the driven gear 6 is fixed in a state concentric with the second rotary shaft 5, and the second rotary shaft 5 is rotatably supported on one of both left and right sides of the frame 1. Here, in a state where the second rotating shaft 5 is fixed to the frame 1, the driven gear 6 may be provided on the second rotating shaft 5 via a bearing (not shown).

Further, in the driven gear 6, a pressure cylinder device (pneumatic or hydraulic) 10 is provided at one point on the side opposite to the side where the second rotation shaft 5 is located. Specifically, the end of the rod part 11 of the pressure cylinder device 10 is rotatably connected to a point on the side of the driven gear 6, one end of the cylinder portion 12 Rotation is freely supported by the frame 1. At this time, the cylinder part 12 of the said pressure cylinder apparatus 10 is provided in the rod 20 provided in the right and left both sides of the said frame 1, and rotation is comprised with respect to the frame 1 freely. It is good.

In addition, although not shown, when the radius of the drive gear 4 is large enough to install the pressure cylinder device 10, the cylinder portion 12 is to be installed on the first rotation shaft 2. You may also

On the other hand, one point of the side of the driven gear (6) to which the end of the rod portion 11 is connected should not be at the center of rotation of the driven gear (6), preferably located on the edge.

In addition, Figure 5 shows another embodiment according to the present invention. As shown, the frame 1 covers the pulley 3, the drive gear 4, the driven gear 6, and the pressure cylinder device 10 in a state including all the ropes 30. The part is made into the built-in case 40 in which the opening is formed, and a compact structure is possible.

In the case where the steel sheet according to the present embodiment is installed in the fixed part of the building, an entrance portion may be formed at the lower end of the built-in case 40 to allow the rope 30 to enter and exit (see FIG. 8). On the other hand, if the evacuator wears directly, it is possible to change the up and down position of the waning machine and then wear down (see Fig. 9). At this time, the rope is bent with an "S". The exit portion of the rope is preferably guided by the rope pulley 33 is inserted into the groove of the pulley 3 to guide the rope accurately.

And, Figure 6 shows another embodiment according to the present invention. In this case, the reinforcing gear 70 meshing with the driven gear 6 is provided. Since the second rotation shaft 5 is supported only on one surface of the built-in case 40, the reinforcement gear 70 is provided with a clearance between the drive gear 4 and the driven gear 6 during actual operation. This is to prevent the gap from opening smoothly.

In addition, in order to increase the stiffness effect, as shown in FIG. 7, the first magnet 60 is fixedly attached to the side surface of the pulley 3 and slides with the first magnet 60 on the inner surface of the interior case 40. It is preferable to fix the second magnet 60 'to be in contact. In the figure, the first magnet 60 is shaped like a brake shoe, and the second magnet 60 'is annular.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 8 and 9.

8 shows a configuration in the case of using a stiffener fixed in advance in a building. The rope 30 is fitted into the groove of the pulley 3 in advance, one end of which hangs to the bottom, and the other end is positioned at the position of the evacuator of the building. When the evacuator hangs on the other end of the rope, the pulley 3 rotates, and the drive gear 4 fixed to the pulley 3 rotates simultaneously. Subsequently, as the drive gear 4 rotates, the driven gear 6 meshed with the drive gear 4 rotates. Since the rod part 11 of the cylinder device 10 is freely connected to one side surface of the driven gear 6, the rod part 11 corresponds to the cylinder part 12 in accordance with the rotation of the driven gear 6. A linear reciprocating motion is made with respect to. At this time, since one end of the cylinder portion 12 is freely rotatable in the frame 1, the entire cylinder device 10 is reciprocated in a hinged manner with respect to the frame 1.

Here, the part showing the direct stiffening function is a part of the pressure cylinder device 10. When the evacuator descends on the rope 30, since the reciprocating drive is made in the pressure cylinder device 10, a damping resistance which is approximately proportional to the descending speed is generated, so that the stiffening effect can be reliably obtained.

Furthermore, adding a frictional effect through magnet contact between the frame 1 (or the built-in case 40) and the pulley 3 results in a greater stiffness effect.

9 is a case where the evacuator comes down directly wearing the waning device according to the present invention, if only the upper and lower positions of the waning device can be changed in the same way as the waning principle of FIG. In this case, what is necessary is just to provide the ropes 30 which concern on this invention in advance several ropes.

According to the present invention of the configuration as described above, since the stiffening effect is achieved through the pressure cylinder device, it is possible to obtain a uniform falling speed compared to the conventional friction crusher has the advantage that the evacuator can be lowered more safely. In particular, the effect is great when descending the elderly or seriously injured.

In addition, since friction is not used, there is an advantage that the contact area between components is very small and the service life is long.

In addition, it is possible to prevent thermal softening of the components, there is also an advantage that the failure rate during the fall is greatly reduced.
