Abstract

PURPOSE:To facilitate dropping of iced snow from the upper surface of a roof by applying Teflon treatment on the outer surface of the roof. CONSTITUTION:Teflon treatment is applied on the outer surface of the roof 14 of, for example, a van trailer 10 and the roof is inclined downward from a central part toward both sides. An electric heater 18 incorporating an electric conduit 16 is embedded in the top part of the roof 14. Teflon treatment facilitates the drop of iced snow on the upper surface of the roof and since the outer surface of the roof is inclined, iced snow laying on the upper surface of the roof is easily dropped through vibration during deceleration. Further, snow is naturally molten by a heating device.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure for a transport box, and more particularly, a roof structure for a van body, a wing body mounted on a truck chassis, a ban trailer pulled by a tractor, or the like. It is about.

[0002]

2. Description of the Related Art The outer surface of the roof of a normal van body, wing body, van trailer or the like is made of a thin plate of aluminum, iron or FRP.

[0003]

The aluminum, iron, and FRP plates that form the surface of the roof of the above-mentioned carrying box have a predetermined coefficient of friction, adhesiveness, and wettability, and also expand and contract depending on temperature. Therefore, for example, when the above-mentioned transportation box travels in heavy snow areas such as Hokkaido and Tohoku in Japan, a large amount of snow is loaded on the top surface of the roof and freezes up, resulting in the following problems inevitably occurring. Although the roof surface is made up of thin plates, it is necessary to increase the plate thickness because the roof plate is distorted by the weight of the snow loaded, and therefore the weight of the transport box itself, the increase in price, and the maximum loading Since the weight is stipulated by law, it is not possible to carry a cargo equivalent to the weight of the loaded snow,
In the case of a wing vehicle in which vanes each having an L-shaped cross section are pivotally pivoted up and down on the left and right sides of the center beam, the weight of the loaded snow causes the center beam to bend, and the loaded snow interferes. There is a problem that the blades do not rotate up and down, especially in the case of a wing car without a center beam to increase the inner size, the blades bend significantly and become unusable. It is necessary to stop once to remove the snow that has frozen due to snow, and climb up on the roof of the above-mentioned transportation box with a ladder etc. to perform snowfall work, but it is dangerous because the foot slips due to snow, especially the length of the roof Approximately 10 meters wide, 2.49 wide
In the case of the Metro Bantrara, it took a considerable amount of time and labor, resulting in a significant delay in transportation time.

An object of the present invention is to provide a roof structure for a transportation box body which can be easily loaded on the roof top surface of the transportation box body to remove the frozen snow.

Another object of the present invention is to provide a roof structure for a carrying box which allows the above carrying box to be loaded on the roof top by vibrations at the time of starting, stopping and accelerating so that frozen snow can be easily removed. Is to provide.

Still another object of the present invention is to provide a roof structure for a transportation box body such that even if the transportation box body travels in a heavy snow area, the snow falling on the roof top surface is naturally melted and the snow is not loaded. Is.

[0007]

In order to achieve the above object, the roof structure of the carrying box according to the present invention is subjected to Teflon processing having a friction coefficient close to ◯ on the outer surface of the roof, and is loaded and frozen. (EN) Provided is a roof structure for a transportation box that can easily remove snow.

By tilting the outer surface of the Teflon-treated roof, the transportation box can be loaded onto the roof surface by vibrations when the vehicle is started, stopped, or accelerated, and frozen snow can be easily removed. Providing a box roof structure

Further, by applying Teflon processing on the upper surface and burying a heating device in the vicinity of the inner side surface of the sloping roof, the snow on the upper surface of the roof is naturally melted to prevent the snow from being loaded on the carrying box. Is to provide a roof structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which the present invention is applied to a roof of a ban trailer, and FIG. 2 is an embodiment in which the present invention is applied to a wing trailer. 3 is a view taken along the line AA of FIG. 1, and FIG.
Shows a BB arrow view of FIG.

The ban trailer 10 shown in FIGS. 1 and 3 is towed by a tractor 12, and the outer surface of the roof 14 is Teflon-coated as shown in black, and it extends downward from the center toward both left and right sides. An electric heater 18 including an electric conductor 16 is buried inside the top of the roof 14 so as to be inclined.

The wing trailer 2 shown in FIGS. 2 and 4.
0 is pulled by the tractor 12, and vanes 24 and 24 'having an L-shaped cross section are pivotally mounted on the left and right sides of the center beam 22 so as to be vertically rotatable about a hinge 26 as a shaft.
The outer surface of the roof portion is subjected to Teflon processing as shown in black, and electric heaters 18 each having an electric conductor 16 incorporated therein are embedded inside the left and right blades 24, 24.

The present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the spirit of the present invention, for example, in a van truck having a luggage box mounted on a truck chassis. Needless to say, it is also applicable.

[0014]

As described above, according to the present invention, since the outer surface of the roof of the transport box is subjected to Teflon processing, it is possible to easily load the snow on the upper surface of the roof and to remove the frozen snow. Since it is inclined, it can be loaded on the roof top by vibrations when starting, stopping and accelerating to easily remove the frozen snow, and because the heating device was embedded near the inner side of the roof, it fell on the roof top. The snow melts naturally and the snow doesn't load.
