Description

[Detailed description of the invention] This invention is a load indicator for tank trucks that carry and transport various liquids such as gasoline, diesel oil, kerosene, and edible oil, especially for tank trucks that transport several types of hazardous materials. Regarding.

Tank trucks are required by law to display the cargo in a designated position at the rear of the tank when loading or transporting hazardous materials. In many cases, various types of cargo are mixed together and transported, and special attention must be paid to the display of the cargo to avoid accidentally unloading other types of cargo that are not intended for use at a destination such as a gas station. No.

Therefore, in the past, in addition to the display boards required by law, separate display boards were provided for manholes, discharge ports, bottom valve control boxes, etc., and each display board was checked one by one during loading. The operator operated the machine to display the name of each load, and then when unloading the load, the operator checked each of the display boards one by one while unloading the load.

Therefore, the operation of this display board is extremely complicated;
Problems have arisen due to errors in operation and confirmation, as well as the mistaken unloading of other types of cargo for which it was not intended. This has been considered a serious problem, especially for tank trucks that transport several types of hazardous materials.

The present invention was developed in view of these circumstances, and it is easy to operate by arranging a pair of interlocking display boards at desired positions on the tank so that they can be checked on the ground and on the upper side of the tank. The purpose of the present invention is to propose a loaded item display device that allows reliable confirmation and prevents unloading of other types of loaded items that are not intended.

The present invention will be described below with reference to the drawings and an embodiment implemented in a tank truck that transports hazardous materials. FIG. 1 is a side sectional view of this embodiment, FIG. 2 is a front view thereof, FIG. 3 is a rear view thereof, and FIG. 4 is a plan view showing how it is attached to a tank truck.

First, the configuration will be explained.

1 and 1 are a pair of display boards, and these display boards 1 and 1 have a circular or polygonal shape, and the front and back surfaces, that is, the opposite surfaces that do not face each other, are marked with "gasoline", "diesel oil", and "gasoline", respectively. An appropriate number of cargo names such as "kerosene" are displayed in correspondence. This pair of display boards 1, 1 is connected to a pin 3 via mounting parts 2, 2.
are fixedly attached to both ends of the connecting shaft 4, respectively. A rotating handle 5 is fixedly provided on the rear end of the connecting shaft 4 by a pin 3. As shown in FIG.

Reference numeral 6 denotes a cover, and in this embodiment, the cover 6 is composed of two casing parts 6a, 6a and a pipe part 6b that communicates them. A connecting shaft 4 is inserted into the cover 6 and rotatably supported, and the tip end of the connecting shaft 4 provided with a rotating handle 5 is bored in the back wall of the casing portion 6a. The display plates 1, 1 are inserted into the through holes 6c and protruded to the outside, and the display plates 1, 1 are housed in the casing parts 6a, 6a, respectively. When the rotation handle 5 is rotated, each display plate 1 is connected to the casing part 6 via the connecting shaft 4.
They will rotate in conjunction with each other within a and 6a.

On the front and back walls of both casing parts 6a, 6a of this cover 6, display window holes 6d, corresponding to the size and position of one of the names of the loaded items displayed on the display boards 1, 1, are provided. 6d is drilled, so
Through these display window holes 6d and 6d, one of the names of the cargo displayed on each display board 1 and 1 is displayed on the front and rear sides (ground and tank upper side).
The instructions will be the same for each.

This cover 6 is attached to each display board 1,
It is attached at a position corresponding to the vicinity of the manhole 7 on the side part along the longitudinal direction of the upper part of the tank so that the display 1 can be confirmed on the ground and on the upper side of the tank (front and rear sides). In this embodiment, the protective frame 8 near the manhole 7 of the tank
By inserting the pipe portion 6b into a through hole drilled in the tank, the rotating handle 5 is attached so as to be located on the upper side (back side) of the tank.

Reference numeral 9 denotes a boss attached to the inner wall of one casing portion 6a of the cover 6, and a through hole 10 into which the boss 9 is inserted is bored in the corresponding display plate 1. A spring 11 is fitted onto the connecting shaft 4 in elastic contact between the mounting portion 2 of the display panel 1 and the pipe portion 6b. The boss 9, the through hole 10, and the spring 11 constitute a locking device for preventing rotation of the connecting shaft 4 and the display plates 1, 1.

As explained above, the loaded object indicator according to this embodiment is configured, and the loaded object indicator is used depending on the number of tank chambers.

Next, the effect will be explained.

When loading liquid into each tank chamber from the inlet of each manhole 7 of the tank truck, turn the rotating handle 5 on the inside of the protective frame 8 (tank top side) on the tank.
By pressing , the boss 9 of the cover 6, which had been fitted into the through hole 10 of the display board 1, is removed from the through hole 10, so that the connecting shaft 4 and the display boards 1, 1 can be moved by turning the rotation handle 5. Interlocking allows for rotation.

Then, turn the rotation handle 5 to select the name of the liquid loaded in the tank chamber from among the names displayed on the display board 1 on the top side of the tank, and select the name of the liquid loaded in the tank chamber as instructed by the display window 6d of the cover 6. Set to . At the same time, the name of the same load is indicated on the display board 1 on the ground side through the display window 6d.

Next, when the rotation handle 5 is released, the display board 1 is pushed back by the action of the spring 11, and the bosses 9 are fitted into the through holes 10 of the display board 1 and locked. Therefore, even after the cargo is transported or unloaded, the name of the cargo indicated by each display window hole 6d does not change, and the same product is surely indicated.

As described above, a loaded object indicator is set for each loaded object.

In the above-mentioned embodiment, the cover 6 consists of two casing parts 6a, 6a and a pipe part 6b that communicates these parts, and is attached to the protective frame 8 of the tank, but the present invention However, the cover 6 is not limited to this, and the cover 6 may be formed as one casing part and may be attached to the tank via a mounting member such as a bracket. Furthermore, the cover 6 may not be formed as a casing but may be formed as a mere plate, and the name of the loaded object displayed on the display boards 1, 1 may not be indicated by the display window hole 6d, and the Alternatively, the side wall of the cover on the upper side of the tank may be removed and the name of the cargo may be indicated using an arrow bar or the like.

In addition, when installing the load indicator on the tank,
If it is sloped downward toward the ground side, it will be easier to check from the ground.

The load indicator for a tank truck according to the present invention is constructed and operates as described above.

Therefore, when loading gasoline, diesel oil, kerosene, etc. into the tank chamber of a tank lorry, you can simply set the load indicator on the top of the tank, and when unloading, the load can be loaded from the ground side. By looking at the instructions on the object display, the type of cargo in each tank room can be reliably confirmed. As a result, conventional problems such as errors in operation and confirmation, unloading of unintended types of cargo, etc. caused by the complexity of operating the display board can be eliminated. This effect is particularly significant in tank trucks that transport hazardous materials.
