DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for loading and unloading an internal combustion engine to and from a test apparatus when performing a performance test on the internal combustion engine before being incorporated in a vehicle body, for example, in an automobile assembly factory. And a pallet device for an internal combustion engine test device.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this type, for example, a structure disclosed in Japanese Utility Model Laid-Open No. 2-129846 has been provided. In this conventional configuration, a piping junction is provided on a base plate capable of supporting an internal combustion engine, and a flexible heat-resistant hose having a base end connected to an exhaust pipe portion provided in the junk is provided at the tip of the heat-resistant hose. An adapter is provided which is freely communicable with the exhaust portion of the internal combustion engine and is engageable via an elastic locking member.

[0003] According to this conventional configuration, after the internal combustion engine is mounted on the base plate, the adapter is opposed to the exhaust portion, and the adapter is moved closer, so that the adapter can communicate with the exhaust portion. Can be fixed by being locked to the exhaust part via an elastic locking body. Further, the adapter may be separated by moving the adapter apart by a force that overcomes the elastic locking force.

[0004]

According to the above-described conventional structure, the adapter is fixed to the exhaust portion by the elastic locking member. Therefore, the elastic locking member is deformed or the elastic force is reduced. It cannot be performed sufficiently, and there is a possibility that it will be separated and fall off unexpectedly during the test by operation.

To avoid such a situation, it is conceivable to increase the elastic locking force of the elastic locking body. However, the greater the elastic locking force, the greater the force required for separation. In this case, the work could not be performed easily and quickly due to the narrow space and the hot adapter at the time of detachment.

An object of the present invention is to provide a pallet apparatus for an internal combustion engine test apparatus in which an adapter can be firmly fixed to an exhaust portion and detachment can be easily and quickly performed.

[0007]

In order to achieve the above object, a pallet apparatus for an internal combustion engine test apparatus according to the present invention is provided with a piping junction on a base plate capable of supporting an internal combustion engine, and an exhaust provided on the junction. A flexible heat-resistant hose having a proximal end connected to the pipe portion is provided. At the distal end of the heat-resistant hose, adapters are provided which can communicate with a pair of exhaust passages formed in an exhaust portion of the internal combustion engine. The adapter comprises a pair of main bodies which are connected to each other so as to be able to approach and separate in the radial direction of the flow path, and the distal ends of both main bodies of the adapter are fitted in both exhaust paths of the exhaust part so as to be freely movable in the radial direction, respectively. The adapter is provided with a locking device operable on the exhaust unit side. The locking device is provided between the pair of main bodies and swings to move the two main bodies toward and away from each other. The consists of an operating lever for swinging, when a pair of the main body of the adapter is separated from each other,
The distal ends of these main bodies are pressed against the inner peripheral surface of the exhaust passage.

[0008]

According to the structure of the present invention, after the internal combustion engine is mounted on the base plate, the operation lever is operated to swing the cam body to bring both adapter bodies close to each other. The adapter faces the exhaust. Next, the adapter is approached to the exhaust unit, and the distal ends of the two main bodies are fitted into the two exhaust passages of the exhaust unit, and the two exhaust passages are respectively connected to the two passages. In this state, by operating the operation lever to swing the cam body in the opposite direction to separate the two main bodies of the adapter from each other, the distal ends of the two main bodies are pressed against the inner peripheral surface of the exhaust path, Then, the adapter is fixed to the exhaust part.

Further, the adapter can be separated by moving both adapter bodies closer to each other by operating an operation lever, and then moving the adapter away from the exhaust unit. As described above, the adapter can be firmly fixed to the exhaust unit through the locking device, and the detachment can be easily and quickly performed by the operation lever.

A cooling water drain pipe 6, an exhaust pipe 7, and the like are provided in the form of a connection pipe.

4 to 8, the heat-resistant hose 8 whose base end is connected to the exhaust pipe section 7 is made of stainless steel. The adapter 10 provided at the distal end of the heat-resistant hose 8 includes a pair of left and right main bodies 31 each having a flow path 30, and these main bodies 31 are connected to each other via a plurality of rods 32 so as to be able to approach and separate from each other. The heat-resistant hose 8 is connected to the end of each channel 30 via an elbow 33.

A conical cam body 34 having a sharp upper end is disposed between the two main bodies 31. The cam body 34 is supported between the lower parts of the two main bodies 31 via a left-right pin 35 so as to be able to swing back and forth. An operation lever 36 for swinging back and forth is vertically provided from below the cam body 34.

The opposing surfaces of the two main bodies 31 are formed as cam surfaces 37 that are inclined so that the front and rear ends approach the opposing sides. At the upper end of the main body 31 and around the flow path 30, an upward annular convex portion 38 is formed, and a recessed step portion 39 that allows the insertion of the annular convex portion 38 is formed at the outer end of the exhaust passage 18. ing.
A locking device that can freely act on the exhaust part 16 side with the above 34 to 39
Make up 40.

According to this embodiment, as shown in FIG. 4, the main body 31 can be brought closer to each other by swinging the operation lever 36 downward to bring the cam body 34 upright. In this state, the adapter 10 faces the exhaust unit 16. Next, the adapter 10 is made to approach the exhaust portion 16, and the annular convex portions 38 of the two main bodies 31 are fitted into the recessed step portions 39, as shown in FIG. In this state, the operation lever 36 is swung upward as shown by the imaginary line in FIG. 8 so that the cam body 34 is turned sideways, so that the main body 31 moves in the direction away from each other via both cam surfaces 37. Then, as shown in FIG. 6, the left and right outer ends of the annular convex portion 38 are pressed against the exhaust portion 16 so that the adapter 10 is connected to the exhaust portion 16.
To be immobilized.

After the internal combustion engine 15 is sent to the test apparatus via such a pallet, various pipes on the test apparatus side are connected to the junction 3, and then the operation of the internal combustion engine 15 starts the intended test. Exhaust gas generated in the internal combustion engine 15 and discharged from the exhaust unit 16 is recovered via the heat-resistant hose 8 and the like.

After the test, the adapter 10 is separated
As shown in FIG. 5, the operation lever 36 is swung downward to
After the two main bodies 31 are brought close to each other by setting the 34 in the upright state, the adapter 10 may be moved away from the exhaust unit 16 as shown in FIG.

When the adapter 10 is made of aluminum, sintered metal, ceramic, or the like, the weight can be reduced.
