Description

  The present invention relates to a tank truck having a liquid shaking prevention structure in a tank.

2. Description of the Related Art Conventionally, a tank lorry has been provided with a wave preventing plate in the tank of the tank truck in order to reduce vehicle shaking caused by movement of liquid in the left-right direction during traveling and to ensure the safety of the traveling vehicle. For example, a wave breaker as shown in the following patent document is known.
JP-A-11-180209

  In the tank lorry shown in Patent Document 1, a plurality of support columns 17 stand in a vehicle tank 11 having a circular or elliptical cross section as shown in FIG. In order to prevent the oil liquid collected in each compartment of the tank from swinging, a wave preventing plate 18 in which a plurality of groove members 18a are arranged in parallel at predetermined intervals is provided in the vertical direction of the column 17. Attached along. The wave preventing plate 18 is made of, for example, stainless steel, aluminum, and the like, and each groove member 18a is configured so that the oil liquid accommodated in the compartment of the tank can be prevented from swinging in the width direction of the vehicle body. It extends in the longitudinal direction of the car body.

  Further, in Patent Document 1, the wave preventing plate may be arranged so as to extend in the vehicle width direction. In this case, the liquid in the tank is shaken in the front-rear direction due to sudden braking or sudden start. There is a description that it will suppress movement.

  However, when the wave preventing plate is arranged so as to extend in the vehicle width direction, depending on the arrangement method, the operation of injecting liquid into the tank or the operation of pouring out of the tank may not be performed smoothly. For example, when a wave breaker plate is arranged in the front-rear direction and the width direction of the tank, when liquid is injected from the inlet at the top of the tank, the movement of the liquid is blocked by the wave breaker plate and cannot move smoothly in the tank. It takes a lot of time to fill the entire area of the tank with liquid. Similarly, in the dispensing operation, the movement of the liquid is blocked by the wave preventing plate and cannot smoothly move in the tank, and it takes a long time to take the liquid out of the tank.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and prevent the liquid in the tank from swinging in the width direction and the front-rear direction without interfering with the operation of injecting and dispensing the liquid. It is to provide a tank lorry capable of ensuring the above.

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that a wave-breaking plate is erected along the front-rear direction in the tank and facing the width direction. A flange that protrudes inward in the width direction is provided as a guide member for the anti-sway plate, and a flange-like upper stopper that protrudes inward in the horizontal direction is provided at the upper end, and the anti-sway plate having buoyancy is provided on the wave-preventing plate along this explosion wave plate is to summarized as providing a possible move between.

  According to the first aspect of the present invention, the anti-swaying plate holds the liquid level in a state where it floats on the liquid level in the tank and prevents the liquid level from swinging in the width direction and the front-rear direction. Even if the steering wheel is turned off, the liquid level does not move in the width direction and the vehicle does not shake in the width direction. Therefore, it is possible to ensure driving safety without shaking up and down. Further, since the rocking prevention plate does not block the flow of the liquid in the tank, it does not hinder the liquid injecting operation and the dispensing operation.

In addition, while preventing movement of the liquid surface in the width direction and the front-rear direction by the rocking prevention plate, it is possible to more reliably prevent the liquid from shaking in the tank, which is particularly likely to affect the operation of the vehicle. Can do.

Further, since the anti-swaying plate is located between the wave-preventing plates , the anti-swaying plate does not move in the width direction and hits the inner wall surface of the tank to damage the tank.

In addition to this, since the anti-swaying plate abuts on the front-rear stopper that protrudes inward in the width direction of the wave-preventing plate, movement in the front-rear direction is restricted. It will not hit the tank wall and damage the tank.

In addition, since the upper stopper that protrudes inward in the horizontal direction of the wave preventing plate restricts the upward movement of the anti-oscillation plate, the anti-oscillation plate rises too much when a large amount of liquid is injected into the tank. There will be no damage to the tank by hitting the inner wall of the tank.

  The wave-preventing plate prevents the liquid in the tank from swinging in the width direction, and the anti-swing plate prevents the liquid in the tank from swinging in the front-rear direction. Can be secured. Also, since the anti-sway plate is located between the opposing wave-proof plates, it does not block even the space outside the wave-proof plate, so the anti-sway plate blocks the flow of liquid in the tank and injects liquid. There is no hindrance to work and dispensing work.

  The tank lorry of the present invention can ensure the safety of operation by preventing the liquid in the tank from swinging in the width direction and the front-rear direction without hindering the liquid injection operation and the liquid extraction operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall side view showing a first embodiment of a tank lorry according to the present invention, FIG. 2 is a transverse plan view of a tank which is a main part thereof, and FIG.

  The tank 2 is mounted on the vehicle body of the tank lorry 1, and its shape is formed in a box shape, for example. The inside of the tank 2 may be divided into a plurality of chambers by partition plates so that different types of oil such as gasoline, kerosene, and light oil can be individually accommodated. And an oil inlet 6 for injecting the oil liquid. Further, an oil supply mechanism 7 is provided behind the tank 2.

  Inside the tank 2, the wave preventing plate 3 extends in the front-rear direction and is vertically provided facing the width direction. In addition, you may make it attach this multiple wave-proof board 3 to the support | pillar which stood up in multiples in the state spaced apart predetermined for the front-back direction and the width direction of the vehicle body.

  For example, the wave preventing plate 3 has a plurality of groove members made of stainless steel, aluminum, or the like arranged in parallel at predetermined intervals along the vertical direction of the support so that the groove members extend in the front-rear direction of the vehicle body. Can be formed. The wave preventing plate 3 suppresses the oil liquid stored in the tank 2 from swinging in the width direction of the vehicle body.

  Then, a floating plate-like rocking prevention plate 4 is disposed between the wave-breaking plates 3 facing each other. The anti-swaying plate 4 is made of a material that is not easily altered by oil. For example, a metal plate made of stainless steel, aluminum, or the like is formed in a hollow box shape and is hermetically sealed by welding so that the oil does not enter the internal space.

Further, flanges 3a projecting inward in the width direction of the tank 2 are provided as guide members at both front and rear ends of the wave preventing plate 3, and a flange-shaped upper stopper projecting inward in the horizontal direction is provided at the upper end of the wave preventing plate 3. 3b is provided. Thereby, the rocking | fluctuation prevention board 4 will be in the state which floated in the space enclosed by the wave-shielding board 3 and the front-back stopper 3a.

  Next, operation and usage will be described. Now, when an oil liquid such as gasoline is injected from the oil filling port 6 at the top of the tank 2, the oil liquid accumulates in the tank 2. At this time, the rocking prevention plate 4 is positioned horizontally in the tank 2 and does not finely divide the entire area of the tank 2, so that the oil liquid is not blocked and moves smoothly in the tank 2. To fill tank 2.

  As the oil is injected, the anti-swaying plate 4 gradually rises upward, but when it reaches the height of the upper stopper 3b, it does not lift any further by contacting the upper stopper 3b. The plate 4 does not rise too much and abuts against the inner wall surface of the upper portion of the tank 2 to damage the inner wall surface of the tank 2.

  Next, when the tank truck 1 starts running with the oil liquid in the tank 2, the anti-swing plate 4 covers the surface of the oil liquid. Even when the brake is stepped on, the rocking prevention plate 4 suppresses the liquid surface of the oil liquid and suppresses the occurrence of waves, thereby preventing the movement of the oil liquid in the width direction and the front-rear direction. As a result, it is possible to prevent the vehicle body from swinging in the width direction and the front-rear direction and to ensure driving safety.

  Further, since the rocking prevention plate 4 is in a floating state in a space surrounded by the wave preventing plate 3 and the front and rear stoppers 3a, the rocking prevention plate 4 moves in the horizontal direction and the wall surface in the tank 2 is moved. The tank 2 is not damaged by hitting.

  Next, when the traveling of the tank truck 1 is stopped and refueling is started by the refueling mechanism 7, the oil liquid is poured out of the tank 2. At this time, the rocking prevention plate 4 is positioned horizontally in the tank 2 and does not finely divide the entire area of the tank 2, so that the oil liquid is not blocked and moves smoothly in the tank 2. And go out of tank 2.

It is a whole side view showing a 1st embodiment of a tank truck of the present invention. It is a cross-sectional top view of the tank which is the principal part of FIG. It is a vertical rear view of the tank which is the principal part of FIG. It is a side view which cuts off one example of the conventional tank truck, and is shown.
