Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of fire engines equipped with multiple working tools such as ladders for use at fire sites, etc.

(b) Conventional technology Conventional fire engines carry work tools such as ladders, which are used at the scene of fires, etc., on the loading platform.

Especially when loading multiple tools, it is recommended to install one tool on the side of the loading platform to make it easier to take out the tools, and to install the remaining tools on the sides of the loading platform, the protrusion from the loading platform will become larger. Since there is a risk of contact with an oncoming vehicle while driving, it is mounted on the top of the loading platform.

(c) Problems to be solved by the invention However, with the above-mentioned method of loading working tools, it is not so difficult to take out the working tools installed on the side of the loading platform, but it is difficult to remove the working tools installed on the top of the loading platform by climbing up onto the loading platform. There was a problem in that it was difficult to take out the equipment quickly, and it was not possible to respond quickly when an emergency was required, such as when extinguishing a fire.

(d) Means for solving the problems The present invention solves the problems mentioned above.
A mount is fixed to the side of the loading platform of the fire engine, and a parallel link mechanism formed by an upper link, a lower link, and a first mount is provided on the mount so as to be movable up and down, and a is provided with a first pedestal that supports the first work tool, and a second pedestal is provided on the top of the first mount.
A mount is rotatably provided, a second holder for supporting a second work tool is provided at a lower part of the second mount, and a second holder is provided between the upper link and the second mount.
The mounting base stands up when the parallel link mechanism rotates downward,
This invention relates to a storage device for a plurality of working tools in a fire engine, which is provided with a connecting link so as to fall down above the loading platform when rotating upward.

(e) Action While the fire engine is running, the parallel link mechanism is rotated upward to store the first work tool supported by the first cradle on the side of the loading platform, and to store the first work tool supported by the second cradle. 2
The working tools are laid down and stored above the loading platform, and the protruding portion from the side of the loading platform is reduced.

When taking out the work tool, the parallel link mechanism is rotated downward to lower the first cradle and the second pedestal, and to extend them to the sides of the loading platform.

At this time, since the second mounting base is connected to the upper link by an articulated link, it gradually stands up as the parallel link mechanism rotates downward, making it easier to take out the second work tool. ing.

(f) Embodiment An embodiment will be described below with reference to the drawings. 1 is a fire engine, and the loading platform 2 of the fire engine 1 is equipped with equipment necessary for fire extinguishing work, such as a water pump and a hose car.

3 is a storage device provided on the side of the loading platform 2 for storing a ladder, which is one of the working tools. The storage device will be explained below with reference to FIG. 2. Reference numerals 4 and 4 are frames fixed to the sides of the loading platform 2, and above and below the frames 4 and 4, upper links 5 and 5 and lower links 6 and 6 are connected at the upper and lower ends. Rotatably supported.

Vertical first mounts 7, 7 are pivotally supported at the other ends of both links 5, 6, and the respective axial support points A, B, C, and D of both links 5, 6 are made into parallelograms to form parallel links. It is adapted to form a mechanism 8.

A first cradle 9 is provided at the bottom of the first mounts 7, 7.
is fixed and extended horizontally.

Below the lower links 6, 6, one ends of cylinders 10, 10, which are pivotally supported on the sides of the loading platform 2, are pivotally supported, so that the parallel link mechanism 8 can be moved up and down by the expansion and contraction of the cylinders 10, 10. It's getting old.

A bracket 1 is mounted on the top of the first mounting bases 7, 7.
1 and 11 are erected, and second mounting bases 12 and 12 are rotatably supported on these brackets 11 and 11.

A second pedestal 13 is fixed to the lower part of the second mounts 12, 12 at right angles to the second mounts 12, 12.

14, 14 are upper links 5, 5 and second mounting base 1
2 and 12, the pivot points F and G at both ends of the articulated links 14 and 14, the pivot points C between the upper links 5 and 5 and the first mounting bases 7 and 7, and the first mounting base 7. , 7 and the second mounting base 12, 12's pivot point E
and form a trapezoid.

Due to the scalene quadrilateral, the second mounting base 12,1
When the parallel link mechanism 8 rotates downward, it becomes an upright state as shown by the dashed line in FIG. 2, and when it rotates upward, it becomes a lying state above the loading platform 2, as shown by the solid line.

A first ladder 15 is placed horizontally on the first pedestal 9 and fixed with a rope 16, and a second pedestal 13 is fixed to the first pedestal 9.
A second ladder 17 is placed horizontally and fixed with a rope 18.

In addition, although a ladder is shown as a working tool in the example, it is not limited to this, and if it is mounted on a fire engine, it will have the same effect. The present invention has the above-mentioned structure, and its operation will now be explained. When running, the cylinders 10, 10 are extended as shown by solid lines in FIGS. 1 and 2, and the parallel link mechanism 8 is rotated upward, and the first ladder 15 is Loading platform 2
Store close to the side.

At that time, the second mounting bases 12, 12 are connected to the connecting link 1.
4, 14, and moved the second ladder 17 to the loading platform 2.
Can be stored compactly upwards.

Next, when each ladder 15, 17 is taken out for fire extinguishing work, the cylinders 10, 10 are contracted and the parallel link mechanism 8 is rotated downward as shown by the dashed line in FIG. 2, and the first ladder 15 is lowered. At the same time, the loading platform 2 is extended to the side.

With this, the operator can remove the ropes 16, 16, easily take out the first ladder 15, and quickly perform fire extinguishing work.

Furthermore, since the second mounts 12, 12 are also lowered and brought into an upright state by the connecting rings 14, 14, the second ladder 17 can be easily taken out by removing the ropes 18, 18 in the same way as the first ladder 15. be able to.

(g) Effects of the invention As described above, the invention provides a parallel link mechanism on the side of the loading platform to support the first mounting base and the first cradle in a vertically movable manner, and furthermore, the first mounting base has a second mounting base. and a second pedestal is rotatably supported, and the second mount and a part of the parallel link mechanism are connected by a connecting link, and the parallel link mechanism is supported on the first pedestal by upward rotation. The first working tool that has been installed is brought close to the side of the loading platform, and the second working tool supported by the second cradle is stored above the loading platform, and both cradle are lowered by rotating downward, and the second mounting pedestal is raised. As a result, each tool can be stored compactly when traveling to prevent accidents such as contact with an oncoming vehicle, and the tools can be quickly taken out during work.
