2. Description of the Related Art Conventionally, a loading platform is moved back and forth on a chassis frame so as to be inclined so that loading and unloading can be easily carried out, as shown in FIG. A guide rail 3 for inclining the carrier having an inclined guide portion 3a between itself and the upper surface 2a of the vehicle 2;
A guide roller 6 is attached to the lower end of a stay 5 provided at the front end 1b of the bed 1 to support the guide rail 3 so that it can roll on the guide rail 3. When the bed 1 is moved to the rear of the vehicle, the guide roller 6 is attached to the guide rail 3. There is a configuration in which the carrier 1 is inclined by being guided, and the rear end 1c of the carrier 1 is in contact with the ground 7 at the maximum inclined position (see Japanese Utility Model Publication No. 55-10176).

However, in this configuration, the lower surface 1a of the carrier 1
Guide portion 3 between the upper surface 2a of the chassis frame 2 and
Since the guide rail 3 for tilting the loading platform having the height a is provided, the loading platform 1 is determined by the rising height a of the inclined guide portion 3a.
The height H of the lower surface 1a of the carrier 1 increases, and the inclination angle when the carrier 1 is inclined so that the rear end 1c is in contact with the ground 7 is increased. When the inclination angle of the carrier 1 is large, when loading a self-propelled machine or the like, the vehicle cannot travel on its own and loading becomes difficult.

Therefore, as shown in FIG. 6, it has been proposed to lower the height H of the lower surface 1a of the loading platform 1 so that the front end 3b of the guide rail 3 for loading platform inclination enters under the chassis frame 2. .

[0005]

Generally, a cross member and various parts for securing rigidity are installed on a chassis frame 2 of a vehicle such as a truck, and a front end 3b of a guide rail 3 is attached to the chassis frame 2. When the guide rail 3 is attached so as to enter below the cross member, the cross member and various parts must be relocated because they interfere with these cross members and various parts. However, there is a problem that the work of transferring the cross member and various parts is troublesome and troublesome, and the strength of the chassis frame 2 is reduced. If the guide rail 3 is mounted so that the front end 3b of the guide rail 3 enters below the chassis frame 2 without relocating the cross member or various parts, the front end 3b of the guide rail 3 is connected to the cross member or the like. It is necessary to retreat to a position where it does not interfere with various parts, and the moving distance of the carrier 1 is shortened. Therefore, the inclination angle when the carrier 1 is inclined such that the rear end 1c is in contact with the ground 7 becomes large.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the moving and tilting device of the loading platform, and can save the trouble of relocating cross members and various parts of the chassis frame, and can prevent the strength of the chassis frame from being reduced. Provided is a transporting and tilting device for a loading platform that can take a long moving distance of a loading platform, has a small inclination angle when the loading platform is tilted so that a rear end thereof is in contact with the ground, and can easily load and unload a load. The purpose is to:

[0007]

According to the present invention, a guide rail for tilting a carrier is provided between a carrier and a chassis frame.

Configured, fitted with a rolling guide roller along the guide rails to the lower end of the stay, and axially supports the support frame having a plurality of supporting rollers supporting the loading platform is slid to the rear of the chassis frame, the chassis frame and the loading platform The above-mentioned subject has been solved by providing a carrier moving cylinder between them and forming a carrier inclining / tilting device.

[0008]

When loading or unloading a load, the load carrier moving cylinder is reduced. Then, the carrier moves rearward on the support rollers of the support frame pivotally supported by the rear part of the chassis frame. At this time, extend the stay cylinder.
If the guide roller attached to the lower end of the stay rolls along the guide rail and the height of the stay increases, the support frame rotates around the support shaft, and the carrier tilts and the rear end Touches the ground. When the loading / unloading operation of the cargo on the carrier is completed, the carrier moving cylinder is extended. Then, the carrier moves forward on the support rollers of the support frame. At this time, reduce the stay cylinder.
For example, the guide rollers attached to the lower ends of the stays roll along the guide rails, and the height of the stays is reduced, so that the loading platform is horizontal and returns to the chassis frame.

[0009] The moving distance of the bed can be long, and the inclination angle when the rear end of the bed is grounded to the ground is small.
Loading and unloading of cargo is easy. In addition, since the height of the carrier on the chassis frame is reduced, stability during traveling is improved.

FIG. 1 is a side view of an apparatus for moving and tilting a carrier according to an embodiment of the present invention, and FIG. 2 is an explanatory view showing a state where the carrier is moved backward and inclined. Here, between the loading platform 1 and the chassis frame 2, an inclined guide portion 3 having a slight rising height is provided.
A guide rail 3 for tilting the loading platform having a is provided, and a stay 5 is provided at the front of the loading platform 1. A guide roller 6 that rolls along the guide rail 3 is attached to the lower end of the stay 5. At the rear of the chassis frame 2, a support frame 9 having a plurality of support rollers 8 for supporting and sliding the carrier 1 is rotatably supported by a support shaft 10. A support leg 11 is provided below the support frame 9. A bed moving cylinder (not shown) is provided between the chassis frame 2 and the bed 1.

FIGS. 3 and 4 are explanatory views of the structure of the stay 5. FIG. The stay 5 has a guide roller 6 and an operating arm 16 pivotally connected by roller pins 15 to the lower end of a swing arm 14 pivotally supported by fixing pins 13 at the front end of a stay base 12 fixed below the front of the loading platform 1. The upper end of the operating arm 16 is pivotally connected to a front end of a stay cylinder 18 attached to the stay base 12 by a movable pin 17. The movable pin 17 is engaged with a longitudinal hole 19 formed in the stay base 12 in the front-rear direction.
When the movable pin 17 is expanded and contracted, the movable pin 17 is moved forward and backward by being restricted by the elongated hole 19, so that the height of the stay 5 changes.

When loading or unloading a load, the load carrier moving cylinder is reduced. Then, the carrier 1 moves rearward on the support rollers 8 of the support frame 9 that is supported by the rear of the chassis frame 2. At this time, the guide roller 6 attached to the lower end of the stay 5 rolls along the guide rail 3, and the stay cylinder 18 extends to increase the height of the stay 5, so that the support frame 9 is supported by the support shaft 9. 1
