Description

Safety evacuation apparatus {An emergency escape apparatus}

The present invention relates to an emergency evacuation device, and more particularly, to a safety evacuation device that can quickly and safely evacuate from the upper floor to the lower floor in case of a disaster.

In general, buildings of a certain size or larger are equipped with a stubborn machine to evacuate in case of a disaster such as a fire or earthquake. The stubborn machine is installed and operated on a window or veranda, and if it is difficult to use the stairs or elevator in the event of a disaster, the evacuee must evacuate to the outside through the stubborn machine.

However, it was difficult for evacuees to evacuate quickly because they had to evacuate while being suspended from a slow-release stubborn rope, and as a result, it was difficult to evacuate many people within a short time. In addition, in the case of the elderly, children, and women, a situation where they refused to use stubbornly due to physical limitations or fear of heights occurred, and a large number of disaster deaths and injuries occurred due to these various reasons.

In order to solve this problem, there is a need for a technology that enables evacuation from the upper floor to the lower floor of the building. Thus, the applicant of the present invention, a frame support unit coupled to the emergency evacuation hole supported on the ceiling slab of the building, a pair of support pillars installed between the frame support unit and the floor slab, and the wire wound as being installed on the upper part of the support pillar. We developed an emergency escape device including a winch, a scaffold that is connected to a wire so that it can be lifted up and down on a support post, and a spring part that rotates the winch reversely so that the scaffold returns to its initial position after descending. As a result, a patent has been registered under the name of emergency escape device with registration number 10-1200375.

With such an emergency evacuation device, the evacuator can evacuate from the upper floor to the lower floor while on the scaffold, and then the mainspring rotates the winch in the opposite direction to raise the scaffold to the initial position so that other evacuees can evacuate in an emergency. I did.

However, in the case of the emergency evacuation device, the leaf spring embedded in the mainspring is corroded over time and the return elasticity is lowered. In this case, the mainspring cannot smoothly return the footrest to the initial position, and thus the mainspring does not operate normally Occurred.

In addition, since the scaffold is located on the lower side based on the surface of the rim support, the evacuee tripped over the rim support during the evacuation process in an emergency situation, leading to secondary injuries.

Thus, when a fire occurs on the lower or upper floor, there is a problem that the flame spreads to other places through the gap between the frame support and the scaffold.

The present invention was created to solve the above problems, and it is possible to eliminate the possibility of failure due to corrosion even after a period of time since the mainspring is not used, and accordingly, it is possible to operate normally even after a long time, so it is easy to maintain. Which can enable management. Its purpose is to provide a safe evacuation device.

Here, that the direction in which the winch part 50 is wound is clockwise or counterclockwise means that the direction in which the winch unit 50 is wound is different.

The frame support 10, as shown in FIG. 1, has a generally rectangular shape, and is fixed to the emergency evacuation hole H1 of the ceiling slab S1.

Profile column 20, as shown in Figs. 6 and 7, the first and second forming fastening rods 22 and 23 in the form of a rod that is formed long along the front edge of the column body 21, and the column body The first and second protective covers 24 formed with first and second rail grooves 24a and 25a formed in the front side by covering the first and second forming fastening rods 22 and 23 as being formed long along (21). ) (25), the pillar hole 26 formed inside the pillar body 21, the guide rail groove 27 formed on the side of the pillar body 21, and the side of the first protective cover 24 It includes a brake rail 28 formed to protrude along. This profile column 20 is manufactured by extrusion molding aluminum, and is used after cutting to a required length.

The first and second molding fastening rods 22 and 23 have a rod shape protruding toward the front side of the column body 21. The first and second molding fastening rods 22 and 23 are formed as one body on both sides of the front edge of the column body 21 when the profile column 20 is extruded, and accordingly, the first and second molding fastening rods ( 22) (23) are naturally formed to have the same spacing and highly precise flatness, and thus the first and second sliders 33, 34, which will be described later, are coupled to the first and second molding fastening rods 22 and 23. ) Enables smooth sliding movement and no flickering during movement.

The first and second protective covers 24 and 25 surround the first and second forming fastening rods 22 and 23 except for the first and second rail grooves 24a and 25a. The first and second protective covers 24 and 25 prevent cement or paint from adhering to the surface of the first and second molding fastening rods 22 and 23 in the process of constructing the building. It protects the first and second molding fastening rods 22 and 23 from dust or foreign matter. Here, the first and second rail grooves 24a and 25a form a passage through which the first and second sliders 32 and 33 of the lift evacuation portion enter and exit, as shown in FIG. 7.

The guide rail groove 27 is formed along the side of the column body 21, guides the main weight 60 to be described later so that it can be raised and lowered in the vertical direction, and shakes during the elevation or separated from the column body 21 Prevent it from becoming.

As shown in Figs. 6 and 7, the lifting skin 30 is spaced apart from the inner circumferential surfaces of the first and second protective covers 24 and 25, and slides on the first and second molding fastening rods 22 and 23. The first and second sliders 32 and 33 with the first and second fastening holes 32a and 33a coupled to each other, and the slider support block 34 coupled to the first and second sliders 32 and 33 ), and the first and second support frames 35 and 36 that are fixed to the slider support block 34 and extend to the front side, and are supported by the first and second support frames 35 and 36. It includes a footrest 37 to board and a handle receiving groove 38 formed in the footrest 38.

After passing through the first and second rail grooves 24a and 25a, the first and second sliders 32 and 33 are separated from the inner circumferential surfaces of the first and second protective covers 24 and 25. It is slidably coupled to the molded fastening rods 22 and 23. These first and second sliders 32 and 33 are formed with cylindrical first and second fastening holes 32a and 33a to slide on the first and second molded fastening rods 23 and 23 forming a rod shape. It is coupled, and accordingly, the lifting table 30 is smoothly elevated along the profile column 20. At this time, as bearings are built into the inner circumferential surfaces of the first and second fastening holes 32a, 33a, the first and second sliders 32 and 33 are more smoothly lifted along the first and second molding fastening rods 22 and 23. Can be moved.

The footrest 37 is installed on the first and second support frames 35 and 36 extending to the front side of the slider support block 34. At this time, a plurality of embossing patterns are formed on the scaffold 37 to prevent the evacuee from slipping.

The handle receiving groove 38 forms a channel immersed in a "U" shape on the surface of the footrest 37, as shown in FIGS. 4 and 14. In this handle receiving groove 38, the guide handle 120, which will be described later, is accommodated so as not to protrude to the surface of the foot plate 37. The lifting table 30 implemented by the handle receiving groove 38 can be implemented slim.

In the profile column 20 and the lifting table 30, the first and second molding fastening rods 22 and 23 have a highly precise flatness because the profile column 20 is molded according to extrusion molding. , Since the first and second sliders 32 and 33 are coupled to the first and second forming fastening rods 22 and 23, the first and second sliders 32 and 33 are profile pillars 20. When ascending or descending along the path, smooth lifting movement as well as no flickering occurs. Accordingly, the evacuee boarding the elevating evacuation unit 30 can safely evacuate without feeling anxious during descent.

In addition, the first and second protective covers 24 and 25 formed on the profile column 20 are the process of constructing a building by wrapping the first and second molding fastening rods 22 and 23 from the external environment. Prevents cement or paint from adhering to the surface of the first and second molding fastening rods 22, 23, and dust or foreign matter adheres to the first and second molding fastening rods 22 and 23 even after time passes. Prevent it from becoming. Accordingly, even if time elapses, the surfaces of the first and second molding fastening rods 22 and 23 can be maintained in a flat state, so that the lifting and lowering skin 30 can be safely lifted and supported at any time.

The centrifugal brake 40 has a structure in which a brake shoe assembly that is axially coupled with the winch part 50 inside the brake drum and moves toward the brake drum by centrifugal force is built in, and is linked to the rotational speed of the winch part 50 to (50) provides a braking force so that it rotates slowly. Since the centrifugal brake 55 is a configuration generally used in the art, further detailed description will be omitted.

The shock absorber 110 is for absorbing a shock applied to the footrest 37 when the lifting and lowering skin 30 is completely lowered to the floor slab S2. Since the shock absorber 110 is a general configuration in the art, further detailed description will be omitted.

The winch part 50, as shown in FIG. 5, has a first winch 51 axially coupled with the centrifugal brake 40, and a second winch having a diameter continuously decreasing from the first winch 51 ( 52) and a third winch 53 connected by the second winch 52. That is, the winch part 50 has a structure connected by a second winch 52 having an inclined surface formed between the first winch 51 having a large diameter and the third winch 53 having a small diameter. For example, assuming that the diameter of the first winch 51 is about 15 cm, the diameter of the third winch 53 will be about 10 cm. Spiral grooves are formed on the surfaces of the first, second, and third winches 51, 52, 53, and accordingly, the lifting wire 70 and the return wire 80 can be wound multiple times without overlapping.

The main weight 60 is elevated along the guide rail groove 27 formed in the column body 21. At this time, in order to ensure that the main weight 60 is not shaken during ascent and descends smoothly, a guide bearing 61 bearing motion along the guide rail groove 27 formed on the side of the column body 21 at the side of the main weight 60 ) Is installed.

One end of the lifting wire 70 is fixed to the winch part 50, and strictly, the first winch 51 having a large diameter, and the other end is connected to the lifting table 30 after being wound in a clockwise direction. One end of the return wire 80 is fixed to the winch part 50, and strictly, the first winch 51 is wound counterclockwise, and the other end is connected to the main weight 60. That is, while one end of the lifting wire 70 and the return wire 80 is fixed to the first winch 51, the lifting wire 70 is wound in a clockwise direction, and the return foreign gear 80 is wound counterclockwise. It is to lose.

By this connection structure, depending on the direction in which the winch part 50 is rotated, one of the lifting wire 70 and the return wire 80 rises and the other descends. At this time, since one end of the lifting wire 70 and the return wire 80 is wound in a clockwise and counterclockwise direction while being fixed to the winch part 50, the lifting wire 70 and the The return wire 80 prevents the winch part 50 from spinning.

If the lifting wire 70 and the return wire 80 are connected as one body and wound around the winch part 50 several times, the winch part 50 suddenly rotates or the weight of the lifting table 30 When a heavy evacuator is boarded, a slip phenomenon occurs between the surface of the winch part 50 and the lifting and return wires 70 and 80, and thus it may turn away. Therefore, it is very important that one end of the lifting wire 70 and the return wire 80 is fixed to the winch part 50 in order to prevent the phenomenon of being idle.

As the winch part 50 has the first, second, and third winches 51, 52, and 53, the torque applied to the rotation shaft of the winch part 50 is varied. For example, when the return wire 80 is released from the first winch 51 having a large diameter, the torque applied to the rotation shaft of the winch unit 50 is the largest and will be released from the third winch 53 having a small diameter. At this time, the torque applied to the rotating shaft of the winch 50 is the smallest. This means that the magnitude of the torque varies depending on the position where the return wire 80 is wound or unwound.

To explain this in more detail, the main weight 60 moves to the upper side of the profile column 20 when the evacuator boards and the lift evacuation part 30 descends to the floor slab S2, and then the main weight 60 ) As it descends by its own weight and raises the ascending and descending skin 30 to the initial position.

At this time, the return wire 80 is released from the first winch 51 at the initial time when the main weight 60 descends from the upper side of the profile column 20, and at this time, since the torque is the largest, the main weight 60 ) Descends quickly, and accordingly, the elevating skin 30 rises rapidly.

Thereafter, when the main weight 60 passes through the middle side of the profile column 20, the return wire 80 is released passing through the second winch 52 on which the inclined surface is formed, and the torque gradually decreases in this process. Because it loses, the main weight 60 gradually descends slowly. In this case, the ascending speed of the lifting table 30 gradually decreases.

And when the main weight 60 passes through the lower side of the profile column 20, the return wire 80 is released as it passes through the third inclined winch 53, and the torque becomes the smallest during this process. The weight 60 slowly descends. In this case, the ascending speed of the lifting table 30 becomes the smallest.

That is, as the return wire 80 moves from the first winch 51 to the third winch 53, the lowering speed of the main weight 60 gradually decreases due to the torque that is changed in the process of being released. The ascending speed of the lifting table skin 30 is greatest when ascending from the floor slab (S2) and gradually decreases as it approaches the ceiling slab (S1).

This operating mechanism is applied in the same way when the evacuator descends from the state in which the evacuation unit 30 is mounted, and accordingly, the evacuee boarding the evacuation unit 30 descends quickly initially and then slowly descends, so that the floor slab (S2) The evacuee can be prevented from falling due to impact from the side. On the contrary, when the lifting shelter 30 returns to the initial position on the ceiling slab (S1) side, it rises rapidly at the beginning and then slowly descends from the ceiling slab side, so that damage due to collision can be prevented.

FIG. 8 is a view for explaining another embodiment of a winch part installed on the upper end of the profile column of FIG. 3, and FIG. 9 is a view for explaining a lifting wire, a return wire, and a sub return wire connected to the winch of FIG. 8 10 is a view for explaining the main weight and the sub weight connected by the return wire and the sub return wire of FIG. 9, and FIG. 11 is a view for explaining the configuration by extracting the winch of FIG. 9.

The winch unit 50 may further include a sub-winch 55 positioned at an upper side of the column hole 26 between the centrifugal brake 40 and the first winch 51. In this case, as shown in FIGS. 10 and 11, one end of the lifting wire 70 is fixed to the fixed end CP of the sub-winch 55 and then wound in a clockwise direction, so that the other end is connected to the lifting table 30 Then, one end of the sub return wire 85, which is a separate configuration from the return wire 80, is fixed to the fixed end (CP) and then wound in a counterclockwise direction, so that the other end is a sub weight (which is a separate configuration from the main weight 60). 65). That is, the sub return wire 85 has one end fixed to the sub winch 55 and wound in a counterclockwise direction and then connected to the sub weight 65, and the return wire 80 includes the first, second, and third winches ( It is connected to the main weight 60 after being wound around 51) 52 and 53 in the counterclockwise direction.

The sub weight 65 is raised and lowered inside the pillar hole 26 of the pillar body 21, and thus is safely raised and lowered without being exposed to the outside.

In the case of such a structure, it is possible to add a sub weight 65 as well as the main weight 60 in order to elevate the elevating skin 30. Accordingly, when the safety evacuation device of the present invention is installed between the ceiling slab (S1) and the floor slab (S2) in a state where the floor height is 5m or more, weight is added to the sub weight 65 to the main weight 60. It can, and accordingly, it is possible to raise the height of the lifting table 30.

12 is a view for explaining the configuration of the emergency brake of FIG.

The emergency brake 90 is to fix the position so that the lifting surface 30 is not lowered from the profile column 20 when the lifting wire 70 is cut off. Such an emergency brake 90 is hinged to a hinge shaft 91 installed on the slider support block 34 of the lifting surface 30, and a brake rail 28 formed on the first protective cover 24 side at one end. ) And a guide bracket that is fixed to the slider support block 34 on the upper side of the brake lever 92 and has a guide hole penetrating to the upper side ( 93) and the brake operating rod 94 that penetrates the guide bracket 93 and is connected to the lifting wire 70, which supports the brake lever 92, and the brake pad ( 92a) includes a spring 95 that applies an elastic force in a direction in which it is moved toward the first molding fastening rod 22.

With this structure, in a state in which the lifting wire 70 is connected to the brake actuating rod 94, the brake actuating rod 94 rotates the brake lever 92 by the weight of the lifting table 30 so that the brake pad 92a ) Keeps the state separated from the brake rail 28, and accordingly, the elevating skin 30 is capable of the above-described elevating operation.

However, when the lifting wire 70 is broken for some reason, the brake lever 92 rotates in the opposite direction about the hinge shaft 91 by the elastic force of the spring 95, and accordingly, the brake pad 92a As is in close contact with the brake rail 28, the elevating skin 30 is no longer elevated and fixed in position.

13 is a view for explaining the configuration of the stopper of FIG. 5.
