Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a drain device for an air tank mounted on a vehicle such as a dump truck for construction machinery.

[Conventional technology]

Vehicles such as dump trucks for construction machinery use air for brake operation and steering operation, so the frame is equipped with an air tank.

On the other hand, since water may collect in the air tank,
A drain valve is installed on the air tank body to drain water.

[Problems to be solved by the device]

Since a large amount of air is used in construction machine dump trucks, the frame is equipped with multiple air tanks, so it is necessary to operate the drain valve for each air tank to drain the air. Not only is draining extremely troublesome, but water drained from the drain valve may scatter around and stain the area around the air tank.

In particular, it is not preferable to dispose the electric component around the air tank, because water will scatter to the electric component to cause a failure.

Then, this invention aims at providing the drain apparatus of the air tank which was able to solve the above-mentioned subject.

[Means for Solving the Problems]

In the valve body 15, a valve 18 that connects and disconnects the inlet hole 16 and the outlet hole 17 is movably provided between the communication position and the blocking position to form a drain valve 6, and the bracket 5 includes a plurality of drain valve 6 valves. The main body 15 is installed side by side and attached, and the inlet hole 16 of each drain valve 6 is connected to the drain hose 7.
Connect to each of multiple air tanks with
21 and both side vertical plates 22,22 have a substantially U shape in a plan view, and mounting plates 23 are provided on the upper sides of the both side vertical plates 22,22, respectively, and the rear surface is extended across the lower parts of the both side vertical plates 22,22. A vertical plate 24 is provided to form a cover body 9 having a hollow downward gutter portion 25, and a mounting plate 23 of this cover body 9 is attached to the bracket 5 and its front vertical plate 21.
A drain device for an air tank that is installed so that the upper part thereof faces the outlet hole 17 of each drain valve 6.

[Action]

Because of this, the drain valves 6 connected to the air tanks are provided side by side on the bracket 5, so that the water in each air tank can be drained by operating each drain valve 6 at one location.

The outlet hole 17 of each drain valve 6 is a front vertical plate of the cover body 9.
By facing the upper part 21, the water drained from the outlet hole 17 hits the front vertical plate 21 of the cover body 9 and flows downward along the trough 25, and is not scattered around.

〔Example〕

As shown in FIGS. 1 and 2, the first, second, and third air tanks 2, 3, and 4 are attached to a mounting horizontal plate 1 arranged on the side of the operator's cab in the front portion of the frame (not shown). At the same time, a bracket 5 is bolted to the rear end edge of the mounting horizontal plate 1, and a plurality of drain valves 6 are arranged side by side on the bracket 5, and the drain hose 7 is provided at the inlet side of each drain valve 6 to form the first hose. , L-shaped pieces 8 connected to the lower portions of the second and third air tanks 2, 3 and 4 and attached to both sides of the bracket 5 so that the cover body 9 is attached so as to face the outlets of the drain valves 6. is there.

As shown in FIGS. 3 and 4, the bracket 5 is provided with a mounting block 11 on a vertical piece 10a of an L-shaped plate 10, and the mounting block 11 has a screw hole 12 for valve mounting and a screw for connector mounting. The hole 13 is formed concentrically through the vertical piece 10a, and the horizontal piece 10b of the L-shaped plate 10 is attached to the attachment horizontal plate 1 with the bolt 14, and the drain hose 7 is attached to the screw hole 13 for attaching the connector. Connector 7a is screwed and connected.

The drain valve 6 has a valve body 15 in which a valve 18 for communicating and blocking the inlet hole 16 and the outlet hole 17 is fitted and inserted into a valve body 15 and is set to a blocking position by a spring 19 and a lever 20 provided on the valve body 15.
Is used to push the valve 18 to the communicating position, and the threaded portion 15a of the valve body 15 is screwed into the valve mounting threaded hole 12 of the mounting block 11 and is attached to the outlet hole 17 thereof.
Is open diagonally downward.

The cover body 9 has a front surface vertical plate 21 and both side surface vertical plates 22, 22 in a substantially U shape in a plan view, and the side surface vertical plate 22 has a substantially L shape in which an upper part is wide and a lower part is narrow. A mounting piece 23 is integrally formed on the wide upper part, and a rear vertical plate 24 is provided over the narrow lower part to form a hollow downward gutter 25,
The mounting plate 23 is connected to the L-shaped piece 8 with a bolt 26 so that the inner surface of the front vertical plate 21 faces the outlet hole 17.

Therefore, by operating the lever 20 of each drain valve 6, the water in the first, second and third air tanks 2, 3 and 4 can be drained, and the drained water can be drained from the outlet hole 17 Further, since it collides with the front vertical plate 21 of the cover body 9 and flows down along the gutter portion 25, it does not scatter around.

[Effect of device]

Since the drain valve 6 connected to each air tank is provided in parallel with the bracket 5, the moisture in each air tank can be drained by operating each drain valve 6 at one location, and the drain work is simplified.

The outlet hole 17 of each drain valve 6 is a front vertical plate of the cover body 9.
21 Since it is opposed to the upper side, the water drained from the outlet hole 17 hits the front vertical plate 21 of the cover body 9 and flows downward along the trough 25, so that it does not scatter to the surroundings. Does not pollute the area around the tank.
