Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary device used when loading a dump truck onto a trailer.

[0002]

[Prior Art]

 The dump truck A has a front wheel 2 and a rear wheel 3 mounted on a vehicle body 1 as shown in FIG. 1, and also has a body 4 which can be lifted and lowered. When the dump truck A is loaded on a trailer B, the dump truck A shown in FIG. As shown in FIG. 2, the front and rear wheels 2 and 3 are traveling on the loading platform 5 of the trailer B.

[0003]

[Problems to be solved by the device]

The width L ₁ of the cargo bed 5 of the trailer B is smaller than the distance L ₂ between the left and right front wheels 2, 3 and the front and rear wheels 2, 3 may come off the cargo bed 5, which is very dangerous.

Therefore, an object of the present invention is to provide a loading assistance device for a dump truck capable of solving the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 A loading assistance device for a dump truck, in which a pair of left and right wheels 13, 13 are supported on a truck body 10 and a support frame 12 is provided on the truck body 10. A loading assistance device for a dump truck, which is made of a rubber bag 20 having a hollow cylindrical shape and containing air.

[0006]

[Work]

 By supporting the front wheel 2 side of the vehicle body 1 of the dump truck A with the support frame 12 and running the wheels 13 on the loading platform 5 of the trailer B, the loading can be safely loaded on the loading platform 5 of the trailer B. By supporting the front wheel 2 side of the vehicle body 1 of the dump truck A with a rubber bag 20, and rolling the rubber bag 20 on the cargo bed 5 of the trailer B, the cargo can be safely loaded on the cargo bed 5 of the trailer B.

【Example】

 As shown in FIG. 3, a trolley body 10 is provided with a supporting frame 12 via a hydraulic jack 11 so as to be able to move up and down, and the trolley body 10 rotatably supports left and right wheels 13 and 13, and a supporting frame 12 is supported. The first and second hoses 14, 15 connected to the extension chamber and the reduction chamber of the hydraulic jack are connected, and one of the quick couplers 16a, 16a, is connected to the first and second hoses 14, 15 and the dump truck side By connecting the other side 16b of the cook coupler 16 to the first and second high pressure pipes 17 and 18, the first and second hoses 14 and 15 can be easily attached to and detached from the first and second high pressure pipes 17 and 18. To do. As a result, the hydraulic jack 11 can be expanded and contracted using the hydraulic power source of the dump truck. The hydraulic power source may be separately installed.

Next, the operation of loading the dump truck A on the trailer B will be described. As shown in FIG. 4, the support frame 12 supports the axle frame 6 of the dump truck A. As shown in FIG. 5, the rear wheel 3 travels on the loading platform 5 of the trailer B, and the support frame 12 is supported by the hydraulic jack 11. Ascend and descend to move the front wheel 2 side of the car body 1 up and down for loading. The vehicle body 13 may be supported in a pair at the front and rear of the bogie main body 10, or the loading platform 5 of the trailer B may be provided with guides for guiding the left and right rear wheels 3, 3.

FIGS. 6 and 7 show a second embodiment, in which a hollow cylindrical rubber bag 20 in which air is enclosed is arranged between the lower surface of the vehicle body 1 and the carrier 5, and the rubber bag 20 is mounted on the carrier 5. The dump truck A is loaded on the loading platform 5 of the trailer B while rolling along.

[0010]

[Effects of the Invention] The front wheel 2 side of the vehicle body 1 of the dump truck A is supported by the support frame 12, and the wheels 13 travel on the load carrier 5 of the trailer B, so that the load can be safely loaded on the load carrier 5 of the trailer B. By supporting the front wheel 2 side of the vehicle body 1 of the dump truck A with the rubber bag 20 and rolling the rubber bag 20 on the cargo bed 5 of the trailer B, the cargo can be safely loaded on the cargo bed 5 of the trailer B.
