Description

[Detailed Description of the Invention] The present invention relates to an inboard working vehicle equipped with a lifter that can be raised and lowered.

When transporting cars by ship, it is not possible to stack cars on top of each other, so mobile decks are built in multiple layers at intervals commensurate with the height of the cars being transported in the hold. I try to line up the cars on the deck. Therefore, when transporting cars with different vehicle heights, it is necessary to change the spacing between the mobile decks. In this way, an inboard work vehicle is used to change the height of the mobile deck.

Figure 1 shows a conventional inboard working vehicle for this purpose, in which a tiltable cabin 2 is mounted on the front part on the chassis frame 1, and a tiltable cabin 2 is mounted on the chassis frame 1. A lifter 3 is provided at the rear of the cabin 2. The lifter 3 is for attaching the mobile deck while adjusting its height, and has a pair of links 4 and 5 on both the left and right sides, and these links 4 and 5
The lifter plate 6 is supported so as to be movable up and down.
A hydraulic cylinder 9 is provided between the connecting pin 7 between the link 4 and the lifter plate 6 and the chassis frame 1. When the hydraulic cylinder 9 operates, the piston rod 10 is pushed out and the links 4 and 5 are rotated. However, the lifter plate 6 is adapted to rise from the position shown by the solid line to the position shown by the chain line in FIG.

The disadvantage of such conventional inboard working vehicles is that while the lifter 3 allows the cabin 2 to be stored at a lower position than the roof when lowered, the cabin 2 cannot be rotated as shown by the chain line in FIG. When the roof is tilted, the rear edge of the roof becomes higher than it would normally be. That is, the height of the cabin 2, which is normally H, becomes H' and becomes higher due to the tilt. Therefore, cabin 2
If you tilt it, it will interfere with the low ceiling inside the ship or the underside of the upper mobile deck. In order to prevent this interference, inboard work vehicles:
Cabin 2 was lowered compared to other vehicles,
A certain amount of head clearance for the crew had to be ensured, and there was a limit.

The present invention was devised in view of these problems, and the roof of the cabin is rotatably attached to the front end of the cabin via a hinge mechanism. Therefore, sufficient head clearance for the crew can normally be secured, and by rotating the roof and tilting the cabin, it is possible to effectively prevent interference between the cabin and the ceiling of the ship and the deck. Become.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows the main parts of the inboard working vehicle of this embodiment, in which a tiltable cabin 16 is mounted on the front portion of the chassis frame 15. Although not shown, a lifter (see Fig. 1) with a mechanism similar to the conventional one is provided on the chassis frame 15 and on the rear side of the cabin 16. It is designed to be installed while adjusting the height of the mobile deck.

A roof 17 of the cabin 16 is constructed separately from the cabin 16, and is rotatably supported by the cabin 16 by a hinge mechanism 19 at the upper front end of the cabin 16, that is, at the upper part of the windshield 18. The rear end of the roof 17 is connected to a piston rod 23 of a cylinder 22 via a bracket 20 and a pin 21. Note that the cylinder 22 may be supported by the frame of the cabin 16. The piston rod 23 has a through hole 2 in the lateral direction as shown in FIG.
4 is formed, and a stopper pin 25 is inserted into this through hole 24. This stopper pin 25 connects to the ring 26 at the top of the cylinder 22.
When in contact with the roof 17, the roof 17 is held substantially horizontally. Further, as shown in FIG. 2, a door 28 equipped with a liftable window glass 27 is attached to the side of the cabin 16.

In such a configuration, when the cabin 16 is to be tilted, by tilting the roof 17 at the front as shown in FIG.
This roof 17 can be prevented from contacting and interfering with the low ceiling inside the ship or the lower surface of the upper mobile deck. To tilt the roof 17,
First, the window glass 27 of the door 28 is lowered. Next, the stopper pin 25 is pulled out from the piston rod 23 of the cylinder 22. This pin 25 is chain 2
Since it is connected to the cylinder 22 as shown in FIG. 3 by 9, it will not run out. When the pin 25 is pulled out and the piston rod 23 is ready to be retracted, the cylinder 22 is operated to retract the piston rod 23 and lower it. Then, as shown in FIG. 4, the roof 17 connected to the rod 23 rotates clockwise about the hinge 19 and tilts.

When the cabin 16 is rotated with the roof 17 tilted in this manner, the state shown by the solid line in FIG. 4 changes to the state shown by the chain line. The heights of the cabin 16 in its normal state and in its tilted state are indicated by h and h', respectively, in FIG. The roof 17 of the ship no longer interferes with the ceiling inside the ship or the lower surface of the upper mobile deck. Therefore, by tilting the cabin 16 of this working vehicle inside the ship, it becomes possible to repair the engine and the like on the spot. Furthermore, it is also possible to ensure sufficient head clearance for the occupant within the cabin 16.

As mentioned above, in the present invention, the roof of the cabin of an inboard work vehicle is rotatably attached to the front end of the cabin via a hinge mechanism, so that the roof can be rotated and tilted. By tilting the cabin, the vehicle height of the cabin can be lowered when the cabin is tilted. Therefore, it becomes possible to perform repairs and maintenance by tilting the cabin even in a narrow space inside the ship.
