Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet device used for loading and unloading an internal combustion engine for performing a performance test with respect to an internal combustion engine test apparatus, for example.

2. Description of the Related Art Conventionally, as seen in, for example, Japanese Patent Laid-Open No. 61-124840, a pallet serves only to support an internal combustion engine and is carried into an internal combustion engine test device via a conveyor device or the like. This internal combustion engine test device has a starter including a motor and a claw, and when the claw is engaged with a ring gear attached to a drive plate integral with the main shaft of the internal combustion engine, the claw is moved by the motor to the main shaft center. The internal combustion engine is started by rotating it around.

According to the above conventional type, by providing a starting device on the internal combustion engine test device side, the internal combustion engine test device becomes large,
And it is expensive. Also, to cover the drive plate,
Since the starter was located in front of it, it was difficult to see water and oil leaks in the drive plate.

An object of the present invention is to provide a pallet device with a starter device, which can make an internal combustion engine test device small and inexpensive, and can clean the periphery of the flywheel of the internal combustion engine.

Means for Solving the Problems In order to achieve the above object, a pallet device with a starter according to the present invention is a pallet device that supports an internal combustion engine having a main shaft, and the pallet has an internal combustion engine with the main shaft axis of the main shaft as a lateral direction. A supporting portion for supporting the engine, a horizontal axis along the main shaft axis of the internal combustion engine supported via the supporting portion, and a pinion facing the ring gear mounted on the main shaft side of the internal combustion engine on the horizontal axis. A starting device provided on the output shaft is provided, and the starting device is provided so as to be rotatable about the axis of the horizontal axis and slidable along the horizontal axis.

According to the configuration of the present invention as described above, the pallet supporting the internal combustion engine is carried into the test device, and the main shaft is started by the starting device in a state where the pallet side junction is connected to the test device side junction. At that time, in the starting device, the pinion can be opposed to the outside of the ring gear by first sliding along the horizontal axis, and can be engaged with the ring gear by rotating around the horizontal axis. . Therefore, by rotating the pinion with the motor before and after engagement, the ring gear can be rotated by the pinion to start the internal combustion engine.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

A flywheel 3 is fixed to a main shaft 2 of an internal combustion engine 1 to be handled, and a ring gear 4 is attached to an outer edge of the flywheel 3. The ring gear 4 is rotatable around a main shaft axis 5.

The pallet 10 is in the shape of a rectangular plate, and support portions 11 that can support the internal combustion engine 1 are erected from a plurality of positions on the upper surface thereof, and a junction 12 is provided on the front end surface side. The internal combustion engine 1 supported by these supporting portions 11 has the main shaft axis 5 in the lateral direction (front-rear direction) and is positioned.

A starting device 15 is provided on one side of the pallet 10. That is, a bracket 17 is fixed to a support member 16 fixed to the pallet 10 to erect one support portion 11, and the main shaft axis 5 of the internal combustion engine 1 supported via the support portion 11 is attached to the upper portion of the bracket 17. A support member 19, which is an example of a rotating member, is attached via a horizontal shaft 18 extending along the axis.

The support member 19 is fitted onto the horizontal shaft 18, and is upright and inclined outward around the horizontal shaft 20 corresponding to the shaft center of the horizontal shaft 18 and along the main shaft center 5. It is rotatable between the bracket and the upright position is regulated by the adjustable stopper 21 from the bracket 17, and the inclined position is the bracket.
It is regulated by a stopper 22 from 17.

The upper portion of the support member 19 is formed in a bifurcated portion in the front-rear direction, and the spline shaft 23 along the horizontal axis 20 is attached to the bifurcated portion. A movable member 25 is externally fitted to the spline shaft 23 via a ball spline portion 24.
25 is slidable along the horizontal axis 20. An operation part (handle) 27 is provided on the movable member 25 via a bracket 26, and the starting device 15 is provided on the movable member 25.

The starting device 15 is composed of a starter motor 28 and a pinion 30 fixed to its output shaft 29.
The cell motor 28 is attached to the movable member 25 so as to face the ring gear 4 from the outside. In order to prevent the movable member 25 from sliding unexpectedly, a locking lever 32 that can be engaged and disengaged with a locking pin 31 provided on the movable member 25 is provided on the support member 19 so as to be vertically swingable.

The test apparatus 40 for the internal combustion engine 1 has a base plate 42 mounted on a base frame 41, and an elevator platform 43 is arranged at a position of the platform plate 42. This is done by a cylinder device 44 mounted between and. A conveyor device 45 and a drive device 46 for driving the conveyor device 45 in the normal and reverse directions are arranged on the lift table 43, and the pallet 10 supporting the internal combustion engine 1 is handled through the conveyor device 45. Further, in front of the conveyor device 45, a junction 47 connectable to the junction 12 of the pallet 10 is provided. 48 indicates a control panel and 49 indicates a piping device.

 The operation will be described below.

The internal combustion engine 1 is loaded on the conveyor device 45 in the lowered position while being placed on the pallet 10 via the support 11. At this time, the starting device 15 is prevented from sliding along the horizontal axis 20 by engaging the locking pin 32 with the locking pin 31 as shown in FIG. As described above, the support member 19 is inclined outward and brought into contact with the stopper 22, so that the pinion 30 is separated from the ring gear 4. In this state, the elevating table 43 is raised by the extension of the cylinder device 44 so that the junctions 12 and 47 are opposed to each other. Then, the junction 47 is moved to project and connected to the junction 12, and then the starting device 15 is operated.

That is, the operator first removes the locking lever 32 from the locking pin 31, and then moves the movable member 25 through the operation unit 27 to the horizontal axis.
Slide along 20. This sliding is performed by being guided by the spline shaft 23, so that the pinion 30 can be opposed to the outside of the ring gear 4. Then, by rotating the movable member 25 around the horizontal axis 20 together with the support member 19 via the operating portion 27, the pinion 30 can be engaged with the ring gear 4 as shown by the solid line in FIG.

Therefore, before and after meshing, the pinion is started by the starter motor 28.
When the pinion 30 is rotated, the ring gear 4 can be rotated to start the internal combustion engine 1. As a result, after the internal combustion engine 1 is put into operation, the support member 19 is rotated outward until it comes into contact with the stopper 22, the pinion 30 is separated from the ring gear 4, and the locking lever 32 is engaged with the engaging pin 31.
To be engaged.

In this way, the desired test can be performed, but at that time, in front of the ring gear 4, etc., that is, at the junction.
The upper part of 47 can be opened cleanly, and maintenance can be easily performed by visual inspection.

Effects of the Invention According to the present invention having the above-described structure, after the pallet supporting the internal combustion engine is carried into the test apparatus, the starter is slid along the horizontal axis to face the pinion to the outside of the ring gear, and the starter is set. By rotating around the axis of the horizontal axis and engaging the pinion with the ring gear, the rotational force of the motor can be transmitted from the pinion to the ring gear to start the internal combustion engine. By providing the starting device on the pallet side in this way, it is possible to provide the test device in a small size and at a low cost, and it is possible to clean around the ring gear (flywheel) of the internal combustion engine, including the water leak check and the oil leak check. Easy maintenance management.
