Description

{Basket For Fire Truck}

The present invention relates to a fire engine boarding box, and more particularly, to a fire engine boarding box installed at one end of a ladder or boom and capable of improving the efficiency of fire suppression or lifesaving work by rotating and turning.

In general, the boarding box for a fire engine is a device that is installed at the end of a ladder or boom to transport firefighters to a relatively high fire or rescue site.

The boarding box for this fire truck includes a basket 10 provided with a door 11 on the front side and installed at the end of the ladder or boom stand (L) as shown in FIG. 1 .

In this conventional fire engine boarding box, the position of the basket 10 is determined by the end position of the ladder or the boom stand (L).

Accordingly, in the case of the conventional fire engine boarding box, when the ladder or boom rod (L) is deployed, the door 11 does not match the angle or height of the access road for firefighters to enter the fire scene or lifesaving site. As the position of the fire engine or the position of the ladder or the boom stand (L) needs to be readjusted, there is a problem in that the time to enter the field is delayed.

In particular, firefighters who are put into a relatively urgent situation often fall while running from the basket 10 to the field when the door 11 does not coincide with the site access road.

2 to 6 , the boarding box for a fire engine according to the present invention includes a basket 100 , a rotation driving unit 200 , and a folding arm 300 .

More specifically, the basket 100 is installed on the front side of the first door 110 that opens and closes to the outside of the basket 100 around the first door pivot 111 and the second door pivot that is installed on the rear surface. It includes a second door 120 that opens and closes inside and outside of the basket 100 with a center at 121 .

At this time, as shown in FIG. 2 , the first door pivot 111 is formed on the bottom side of the basket 100 so that the first door 110 extends toward the front side of the basket 100 . can be opened

Accordingly, the first door 110 may serve as a ladder connecting the basket 100 and the fire or lifesaving site access road.

More preferably, the first door 110 may be formed to extend in length by applying an antenna structure or the like.

Meanwhile, the second door 120 is provided with two and can be opened and closed on both sides by a hinge including the second door pivot shaft 121 .

More preferably, the second door 120 pivots so that one end that is not coupled to the second door pivot shaft 121 can face the outside and the inside of the basket 100 based on the closed state of the second door. The angle is formed to be 180° or more.

That is, the boarding box for a fire engine according to the present invention is preferably formed such that the first door pivot 111 and the second door pivot 121 are perpendicular to each other.

In addition, it is preferable that the width of the second door 120 is wider than the width of the folding arm 300 .

That is, when one end of the second door 120 that is not coupled to the second door pivot 121 is opened toward the inside of the basket 100 , the passage by the opening of the second door 120 is It is preferable that the width is wider than the width of the folding arm 300 .

Meanwhile, the rotation driving unit 200 is coupled to the bottom surface of the basket 100 to rotate the basket 100 about the rotation shaft 210 .

In addition, the rotation driving unit 200 may further include a structure such as a stopper (not shown) that can prevent the basket 100 from being rotated by shock or vibration when the rotation at a desired angle is completed.

More preferably, the rotation driving unit 200 is coupled to the center of gravity of the basket 100 to prevent a continuous load from being applied to either side of the basket 100 .

On the other hand, the folding arm 300 has one end fixed to the ladder or boom stand (L) and the other end coupled to the rotation driving unit 200, and at least one or more pivot shafts 310 orthogonal to the rotation shaft 210. The rotation driving unit 200 is pivotally moved around.

That is, the folding arm 300 pivots and moves the basket 100 together with the rotation driving unit 200 about the pivot shaft 310 .

In addition, the folding arm 300 may be formed in multiple joints depending on the number of the pivot shaft 310 .

More specifically, the pivot 310 includes a first pivot 311 formed on the side of the rotation driving unit 200 and a second pivot 312 that is formed on the ladder or boom stand (L) side. The folding arm 300 may be formed of three joints.

At this time, it is preferable that the first pivot shaft 311 rotates the basket 100 together with the rotation driving unit 200 by 90° or more.

Meanwhile, FIG. 7 is a side view illustrating a fire engine including a boarding box for a fire engine according to an embodiment of the present invention.

The operation method of the boarding box for a fire engine according to the present invention with reference to FIGS. 2 to 7 is as follows.

Through the second door 120, the basket 100 in which the firefighters boarded is transferred to the fire or lifesaving site by the ladder or boom L, as shown in FIG.

Thereafter, the basket 100 is deployed by the folding arm 300 so that the first door 110 or the second door 120 can be directed toward the fire or lifesaving site access road.

In this case, when the fire or lifesaving site access road does not match the height of the basket 100, it is preferable that the first door 110 be positioned at the fire or lifesaving site access road.

That is, since the angle of the first door 110 can be adjusted as it is opened toward the front side with respect to the first door pivot 111 , the height difference from the bottom surface of the basket 100 is the fire or lifesaving. It can serve as a ladder that spans the site access road.

In this case, as described above, the first door 110 may further extend in the longitudinal direction.

In addition, the length and angle of the folding arm 300 are adjusted by the first pivot 311 and the second pivot 312, so that the distance between the basket 100 and the fire or lifesaving site access road. and angle adjustment is possible.

On the other hand, when the fire or lifesaving site access road is the same height as the basket 100, the second door 120 may be located in the fire or lifesaving site access road.

To this end, the basket 100 is the first door 110 or the second door 120 by the rotation driving unit 200 as shown in Figs. It can be rotated so that it can be positioned in

On the other hand, when fire suppression or lifesaving is completed and the ladder or boom stand (L) is folded and the firefighter gets off, the basket 100 is moved to the second position by the folding arm 300 as shown in FIG. It pivots around the pivot shaft 310 so that a part of the folding arm 300 is inserted toward the door 120 .

At this time, the second door 120 maintains an open state such that the end not fastened to the second door pivot 121 faces the inside of the basket 100 .

In addition, the upper surface of the first door 110 is formed to face upward.

Accordingly, in the boarding box for a fire engine according to the present invention, as shown in FIG. 7 , a portion protruding from the upper surface of the ladder or boom L in the height direction can be minimized.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made.

In addition, although the effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.
