Abstract

PURPOSE:To prevent liquid from remaining in auxiliary pipes, by enabling the upward and downward swing of the auxiliary pipes to tilt them depending on the place of discharging. CONSTITUTION:When the place of discharging is on the left-hand side, the stopper pin 27 of an operating lever 23 is released to turn the lever and secure it in a position shown by a one-dot chain line in the drawing. As a result, an auxiliary pipe 8 is swung about a rotary coupling 9 to a position shown by a one-dot chain line, so that the auxiliary pipe is tilted leftward as a whole. After that, a bottom valve 5 is opened and a left-hand shutoff valve 12 is opened to discharge liquid out of a tank 1 leftward. The liquid is thus prevented from remaining in the auxiliary pipe 8. After the discharge, the stopper pin 27 is released to turn the lever 23 to a position shown by a full line, to make the auxiliary pipe 8 horizontal and secure it in the horizontal position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge device installed in a tank car, and particularly to a 111-mount device capable of discharging from either the right or left side.

In general, the discharge device of a tank car has openings on the left and right sides so that the tank can be discharged from either the left or right side depending on the situation at the discharge location.

However, in the past, one end of the main piping was connected to a bottom valve installed at the bottom of the tank, and part of the auxiliary piping, with openings at both ends located on the left and right sides, was fixed horizontally to the other end of the main piping. Because of the structure, even after the discharge is finished, a small amount of discharged liquid remains at the bottom of the auxiliary pipe, and if the vehicle body is tilted to the opposite side from the direction of discharge, the amount remaining will be very large. Nita(
There was a drawback to that.

In order to solve the above-mentioned drawbacks, the present invention makes the auxiliary pipe vertically swingable so that it can be tilted to the left or to the left.

The following examples will be explained with reference to the drawings. (1) The vehicle body (
2) A tank mounted on top via a safety frame (3), the tank (]) is divided into four chambers (4), each chamber (4)...・Bottom valves (5) are installed at the bottom.

The bottom valve (5) is equipped with a discharge pipe (6) which will be described later.
)... is connected, and the discharge pipe (6)...
The liquid inside each chamber (4) can be discharged in any direction to the left or right.

The above-mentioned 1/1 outlet piping (0)... is the main piping (7).
...and the auxiliary piping (8)... and the rotary joint (
9) They are connected via 2, and the υ1 output pipe (6) is provided corresponding to each chamber (4). Since they have almost the same structure, one will be explained.

The main pipe (7) is bent at approximately 90 degrees, and one end is connected to the bottom valve (5).
) is connected to the lower end of the tank (1'), and the other end extends in the front and rear direction of the tank (1).

The auxiliary pipe (8) is a straight pipe or a curved pipe, and is formed into a plane so that there is "1 part (10) (to
) or male frame (3i (3) main area long hole (11
,) Pass through (11) and place 1 on the left and right sides? y has been done. Also, in the vicinity of the double-opening I'' part Qllll (10), there is an on-off valve (12) (12) or a BJ et al.

ing.

The rotary joint (9) has an outer ↑191 (13) and an inner cylinder (14).
), the outer cylinder (13) is fixed to the other end of the main pipe (7) with a port (15), and a
It is also fixed to the -C tank ('') through - (1, 6), making the inner cylinder (14) rotatable within the outer cylinder (13) and connecting it to the approximately medium heat of the auxiliary pipe (8). Set up BJ T-shaped section (17)
It is fixed to one end with a bolt (18).

A holding device (1, 9) (19) is provided between the auxiliary pipe (8) and the subframe (31 (3)) to keep the auxiliary pipe (8) in a horizontal state at all times. , the holding device (19) (19) is a refractive link (20)
Both ends of (20) are pivotally supported on the auxiliary pipe (8) and subframe (3) +3+, and the bending link (20) (
20) A spring (21) (21) is installed between the center and the subframe (3) (3).
) (21) is attached so that the auxiliary pipe (8) (81) has a free length in a substantially water-tight state.

There is an auxiliary pipe (8) between the auxiliary pipe (8) and the vehicle body (2).
8) is provided with an operating device (22) for lowering the control lever (23) by -1.
-1- to the bracket l-(24) on the vehicle body (2) side.
A pin (26) on the side of the auxiliary pipe (8) is pivotally supported so as to be movable downward, and is inserted into a long hole (25) provided in a part of the operating lever (23).
is inserted, and furthermore, a part of the operating lever (23) can be fixed to the bracket +- (24) at an appropriate position using a stopper pin (27).

In the embodiment, an operating device is provided for each auxiliary pipe, but one operating device can be used to control multiple auxiliary pipes.
Even if it is rotated in the opposite direction, the same effect can be obtained.

The present invention has the above-mentioned structure. Next, the operation will be explained. First, the vehicle body (2) is stopped at a predetermined discharge location.

Next, if the discharge location is on the left side (lower side in Figure 1), the stopper pin (27) of the operation lever (23) is
), rotate the operating lever (23) counterclockwise to the position indicated by the dashed line, and press the stopper pin (23) at that position (,
7) Fix it.

Then, the auxiliary arrangement ¥1 (8) is centered around the rotating joint (9).
・The whole body swings to the position indicated by the dotted chain line, 'x: fl! I
I becomes (tJj oblique state).

In the above state, open the bottom valve (5) and open the left on-off valve (12).
By opening the tank, the liquid in the tank (1) can be discharged to the left side, and any residue in the auxiliary pipe (8) can be reliably eliminated.

When the discharge is finished, remove the stopper pin (27), rotate the operating lever (23) clockwise to the solid line position to level the auxiliary pipe (8), and at that position, turn the operating lever (23)
is fixed to the stopper bin (27).

At that time, the auxiliary pipe (8) has a holding device (19) (1
, 9), the operating lever (23) can be operated with a small amount of force.

As described above, the present invention connects a part of the auxiliary piping with openings at both ends located on the left and right sides to the main piping via a rotary joint,
Since the auxiliary piping can be swung vertically, the auxiliary piping can be tilted depending on the discharge location, and the conventional drawback of liquid remaining in the auxiliary piping can be reliably solved.
