Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a discharge device for a tank car, and particularly to a discharge device capable of discharging from either the right or left side.

(b) Prior Art 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 of the tank, was fixed horizontally to the other end of the main piping. It has a similar structure.

(c) Problems to be solved by the invention For this reason, 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 in the opposite direction to the direction of discharge. The drawback was that the residual amount was extremely large.

(d) Means for Solving the Problems The present invention has been made to solve the above-mentioned problems.One end of the main pipe is connected to a bottom valve at the bottom of the tank mounted on the vehicle body, and the main pipe is At the other end of
A substantially central portion of an auxiliary pipe whose openings at both ends are located on the left and right sides of the tank is swingably connected via a rotary joint, and an auxiliary pipe is connected between the auxiliary pipe and the vehicle body around the rotary joint. It is characterized by a structure that includes an operating device that swings and a support device that supports the auxiliary piping in a fixed position.

(e) Effect If the discharge location is on the left side of the tank, use the operating device to tilt the auxiliary piping to the left and fix it in this position using the support device.

Thereafter, by opening the bottom valve and opening the left opening/closing valve, the liquid in the tank can be discharged to the left side, thereby ensuring that no residue remains in the auxiliary pipe.

When the discharge is completed, the auxiliary pipe is leveled by the operating device and fixed in this position by the support device.

(f) Example An example will be described below with reference to the drawings. Reference numeral 1 denotes a tank mounted on a vehicle body 2 via a subframe 3, and the tank 1 is divided into four chambers 4...
A bottom valve 5 is provided at the bottom of each chamber 4.

A discharge pipe 6, which will be described later, is connected to the bottom valve 5, and the liquid in each chamber 4 can be discharged in any direction on the right and left sides of the tank 1 through the discharge pipe 6. It's summery.

The discharge pipe 6... connects the main pipe 7... and the auxiliary pipe 8... via a rotary joint 9..., and the discharge pipe 6... is provided corresponding to each chamber 4... However, since they have almost the same structure, only one will be explained.

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

The auxiliary pipe 8 is formed as a straight pipe or a curved pipe so as to form one plane, and openings 10, 10 at both ends pass through vertically long holes 11, 11 of the sub-frames 3, 3, and are connected to the left and right sides of the tank 1. is being used. Also, on-off valves 12, 12 are provided near the openings 10, 10 at both ends.

The rotary joint 9 consists of an outer cylinder 13 and an inner cylinder 14, and the outer cylinder 13 is connected to the other end of the main pipe 7 by a bolt 15.
The inner cylinder 14 is fixed to the tank 1 via the mounting bracket 16, and the inner cylinder 14 is fixed to the outer cylinder 13.
It is made rotatable within the auxiliary pipe 8 and is fixed to one end of a T-shaped portion 17 provided approximately in the center of the auxiliary pipe 8 with a bolt 18.

Holding devices 19, 19 are provided between the auxiliary piping 8 and the sub-frames 3, 3 to keep the auxiliary piping 8 in a horizontal state at all times, and the holding devices 19, 19 are attached to the bending links 20, 20. Both ends are pivotally supported on the auxiliary piping 8 and the subframes 3, 3, and springs 21, 21 are provided between the centers of the bending links 20, 20 and the subframes 3, 3.
1 and 21 are attached so that the auxiliary pipes 8 and 8 have free lengths in a substantially horizontal state.

An auxiliary pipe 8 is provided between the auxiliary pipe 8 and the vehicle body 2.
An operating device 22 is provided for moving the operating lever 23 up and down, and the operating device 22 has a part of the operating lever 23 pivoted on a bracket 24 on the vehicle body 2 side in the vertical movement direction. A pin 26 on the side of the auxiliary pipe 8 is inserted into a long hole 25 provided in the section.

Reference numeral 27 denotes a support device that can support the auxiliary pipe 8 in a fixed position, and this support device 27 is inserted into the stopper pin 27 between the hole 29 of the extending member 28 of the operating lever 23 and the hole 30 of the bracket 24. The auxiliary pipe 8 can be fixed in a fixed position.

In the embodiment, an operating device is provided for each auxiliary pipe, but similar effects can be obtained even if a single operating device is used to move a plurality of auxiliary pipes up and down.

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

Next, if the discharge location is on the left side of the tank 1 (lower side in Figure 1), remove the stopper pin 27 of the operating lever 23 from the state shown by the solid line in Figure 4, and rotate the operating lever 23 counterclockwise to the position indicated by the dashed line. Then, the stopper pin 27 is inserted between the hole 29 of the extending member 28 and the hole 30 of the bracket 24.

Then, the auxiliary pipe 8 swings around the rotary joint 9 to the position indicated by the dashed line, and the whole becomes tilted to the left.

In the above state, open the bottom valve 5 and open the left on-off valve 12.
By opening the tank 1, 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 completed, 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 extend the extension member 2.
A stopper pin 27 is inserted between the hole 29 of 8 and the hole 30 of the bracket 24 to fix the auxiliary pipe 8.

At that time, since the auxiliary piping 8 is provided with holding devices 19, 19, the operation lever 2 can be moved with a slight force.
3 can be operated.

(g) Effects of the invention 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 of the tank to the main piping via a rotary joint, making the auxiliary piping swingable. 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.
