Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a vehicle piping connection device that connects piping installed in a vehicle.

[Technical background of the invention and its problems]

Figure 1 shows a schematic plan configuration of a typical diesel vehicle. In the figure, 1 is a car body frame, and on the floor of this car body frame 1 are a driver's cab 2, an air control room 3, an electrical room 4, and an engine room 5. The driver's cab 6 is placed in the driver's cab 2, the 9-control unit 7 is placed in the air control room 3,
The electrical room 4 is provided with an electrical equipment unit 8, and the engine room 5 is provided with a diesel engine 9, a generator 10, an air compressor 11, and the like. On the side of each room 3, 4.5 except for the operator's cab 2, there are doors 12 for maintenance and inspection of equipment.
... is provided.

The 9-control unit 2 provided in the air control room 3 has the function of, for example, feeding compressed air into an air cylinder (not shown) and operating a brake mechanism etc. via the air cylinder. As shown, it is mounted on the floor of the vehicle body frame 1 and supported via a unit mounting base 13f. In other words, a unit mounting base 13 is attached to the floor of the vehicle body frame 1 by welding or the like, the moat unit 7 is fixed to this unit mounting base 13 with screws 14, and this moat unit 7 is covered with the moat chamber 3. There is. This moat unit 7 is equipped with an air storage tank 16, 16, a dust remover 17, a pressure reducing valve 18, a control valve 19, 20, 21, and a plurality of unit side piping 22 for air supply derived from these. The ends of the unit side pipes 22 are arranged so as to face the floor surface of the vehicle body frame 1 and to be parallel to each other in a straight line.

On the floor of the vehicle body frame 1, the unit side piping 22 and
A plurality of vehicle body side pipes 23 corresponding to... are drawn out, and when the moat unit 7 is mounted on the floor of the vehicle body frame 1, the units are connected to the terminals of these vehicle body side pipes 23... The ends of the side pipes 22 are connected by joints 24, respectively, and the moat chamber 3 is fixed to the vehicle body frame 1 and the driver's cab 2 with screws 15. After such assembly work is completed, open the door 12 and connect the joint 24.
All inspections and maintenance are performed for tightening, air leaks, etc.

However, in such a means, when all the unit side piping 22... and the vehicle body side piping 23... are connected, a joint '24... is used for each of them,
Further, while aligning the pipes, the work must be done within a narrow space inside the trenching unit 7, which makes the work troublesome and lacks efficiency.

[Purpose of the invention]

This invention was made with attention to these points, and its purpose is to connect unit side piping and vehicle body side piping all at once without the need for troublesome work such as alignment. An object of the present invention is to provide a vehicle piping connection device that can be efficiently connected.

[Summary of the invention]

That is, this invention provides a vehicle body underframe and a moat unit,
A piping seat is provided to which the car body side piping and the unit type piping are connected, and these piping seats are joined to each other according to the installation of the empty 1irlf unit, and by this joining, the corresponding car body side piping and unit side piping are connected to each other. Both are connected through their respective piping seats.

[Implementation sequence of the invention]

An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numeral 31 denotes a vehicle body underframe; 3; and above the floor of the vehicle body frame 31, a plurality of vehicle body side pipes 34 corresponding to the unit side pipes 33 are drawn out. Heavy body frame 1
A unit mounting base 35 is provided on the floor of the unit, and the city side pipe seat 3 is placed horizontally on this unit mounting base 35.
6 are integrally formed. And this car body side switching seat 3
6 are connected to the ends of the vehicle body side piping 34 by means such as screwing, and guide pipes/37° 37 are integrally provided on the upper surface of both ends of the vehicle body side turning seat 36. The moat unit 32 is mounted on a unit holder 35 and fixed with screws 38 and 38. A single unit-side turning seat 39 is formed so as to be horizontally arranged in this trench unit 32, and the unit-side piping 33 is connected to this unit-side piping bird 39 by means such as screwing. .

This unit side switching seat 39 is joined to the upper surface of the vehicle body side switching seat 36, and guide holes 40, 40 are formed on both end sides of this unit side switching seat 39, and these guide holes 40.
The guide pins 37, 37 are fitted into the guide pins 40. Piping holes 41 . . . , 42 , .

42..., the unit side piping 33... and the vehicle body side piping 34... communicate with each other through the corresponding ones. For example, annular recesses 6 and 43 are formed on the upper surface of the car body cut-and-cut pipe seat 36, respectively, around the piping holes 41, and O-rings 45 are formed in these grooves 43.・ is installed, and these O-rings 45・
... maintains the airtightness between the piping holes 41 ..., 42 ....

In such a configuration, when the 9-control unit 32 is mounted on the unit mounting base 35 while fitting the guide pin 37° 37 into the guide hole 40. It is joined to the car body cut-and-cut pipe seat 36, and the piping holes 41... and 42... are opposed to each other,
As a result, the unit side piping 33 and the vehicle body side piping 34 corresponding to each other communicate with each other, and the connection is achieved all at once. 9 system unit 32 has guide pin 37°32
By fitting the guide holes 40 and 40, it can be mounted smoothly and in an accurate position, and even if the piping hole 41...
Even if there is a slight deviation in the opposing positions of ・ and 42, it will not affect the communication between the unit side piping 33 and the vehicle body side piping 34. Airtightness is also reliably maintained by the O-rings 43, and there is no risk of air leakage.

In this way, the 9-system unit 32 can be attached to the vehicle body frame 3 without using individual joints or requiring special alignment.
The unit side piping 33... and the vehicle body side piping 34... can be connected all at once depending on the work to be carried out on the vehicle body 1, and therefore the connection work can be easily and efficiently performed.

〔Effect of the invention〕

As explained above, according to the present invention, multiple pipes can be easily and efficiently connected together without using individual joints or aligning them as in the past. play.
