the inside of the carriage body 2 is also provided with a third flat plate 10, and the third flat plate 10 is positioned between the first flat plate 8 and the second flat plate 9 and is used for connecting the first flat plate 8 and the second flat plate 9.
The embodiment is based on two plates dividing the interior of the carriage body 2 into two placement areas, wherein a first plate 8 is positioned above the tire of the fire truck for utilizing the carriage body 2 space above the tire; the second flat plate 97 is located at the rear side of the fire truck tire for utilizing the space of the carriage 2 above the rear side of the tire. In this embodiment, the top of the carriage 2 is fixed in height, and the second plate 9 is lower than the first plate 8, so that in the case where the widths of both plates (i.e., the dimensions in the front-rear direction of the fire truck) are equal, the space between the second plate 9 and the top is larger than the space between the first plate 8 and the top. Therefore, when the width of the first flat plate 8 is fixed, if the width of the second flat plate 9 is increased, the accommodation volume can be enlarged, and the space utilization can be improved; at this time, the width of the carriage body 2 increases along with the increase of the width of the second flat plate 9, so that the gravity center of the fire truck gradually moves backwards, and when the gravity center moves backwards excessively, the situation that the fire truck is unstable in running and easy to turn over (often climbs a slope in an off-road scene and the gravity center moves backwards and is easy to turn over) can be generated. In this regard, the present application adjusts the contradiction between the space utilization and the running stability by determining the ratio of the widths of the first plate 8 and the second plate 9. According to the method, the ratio of the widths of the first flat plate 8 to the second flat plate 9 is 1.7-2.3 through multiple simulation and physical experiments, and when the ratio of the widths of the first flat plate 8 to the second flat plate 9 is 1.7-2.3, the running stability of the fire truck can be ensured; when the ratio is the minimum, the maximum space utilization rate of the fire truck can be ensured under the condition of stable running.
In yet another alternative embodiment, the third plate 10 is two plates that are not connected; in the left-right direction of the fire truck, the left side surface of the third flat plate 10 on the left side is fixedly connected with the left side wall of the carriage body 2, and the right side surface of the third flat plate 10 on the right side is fixedly connected with the right side wall of the carriage body 2;
a fourth flat plate 11 placed in a horizontal direction is further arranged between the two third flat plates 10 in the carriage body 2 based on the left-right direction of the fire truck; the height of the fourth flat plate 11 is equal to that of the second flat plate, and the fourth flat plate 11 is connected with the middle part of the second flat plate in the front-rear direction of the fire truck;
the front side surface of the fourth flat plate 11 is fixedly connected with the front side wall of the carriage body 2; a closing plate 12 is arranged at the left side edge and the right side edge of the fourth flat plate 11, the upper side surface of each closing plate 12 is fixedly connected to the lower side surface of the first flat plate, the left side closing plate 12 is connected with the right side edge of the left side third flat plate 10, and the right side closing plate 12 is connected with the left side edge of the right side third flat plate 10;
the fourth flat plate 11 has a size of 850-950mm in the left-right direction of the fire truck.
The fourth flat plate 11 of the embodiment is arranged in the area of the off-road chassis 3 above the chassis between the rear tires, and the fourth flat plate 11 is just below the first flat plate 8, so that the space below the first flat plate 8 above the chassis between the rear tires can be fully utilized, and the accommodating volume of the fire-fighting truck body 2 is further increased; meanwhile, based on the box with the side opening formed by the fourth flat plate 11, the closing plate 12 and the first flat plate 8, long-strip fire-fighting appliances such as shovels, cro bars and the like are conveniently placed; the opening direction of the side face of the box faces the back door, so that the back door can be conveniently opened to place or take the appliance; moreover, if jolt occurs in the running process of the fire truck, the sealing plates 12 positioned at the two sides of the box can limit the shaking degree of the strip fire extinguisher, reduce the position of articles from being disturbed, and further help to improve the efficiency of taking articles by firefighters.
In yet another alternative embodiment, both of the third plates 10 are fixedly coupled to the upper surface of the second plate based on a predetermined inclination angle.
In this embodiment, the preset inclination angle is smaller than 90 degrees, that is, the included angle between the third plate 10 and the upper surface of the second plate 9 is smaller than 90 degrees.
The first plate 8 is positioned higher and it is more laborious to directly carry the article from the first plate 8 to the ground. The present embodiment can be used to smoothly transfer an article such as a weight of the first flat plate 8 to the second flat plate 9 which is closer to the ground through the third flat plate 10 by setting the inclination angle of the third flat plate 10, and the firefighter can smoothly transfer the article and save the strength of the firefighter by transferring the article from the second flat plate 9 to the ground.
The disclosure of the embodiments of the present utility model is merely a preferred embodiment of the present utility model, and is merely for illustrating the technical scheme of the present utility model, but not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that; the technical scheme recorded in the various embodiments can be modified or part of technical features in the technical scheme can be replaced equivalently; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
