Abstract

(57) [Abstract] [Purpose] To obtain a rolling compaction vehicle in which different wheels can be exchangeably attached to one vehicle body. [Structure] A mounting device common to each wheel is provided above a coupler mounted on the wheel. Wheels with a width greater than the vehicle body width are mounted with a spacer between the coupler and the vehicle body frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rolling compaction vehicle using iron wheels and / or tires, and more particularly to a rolling compaction vehicle suitable for 2.5 to 4 ton wheels.

[0002]

[Prior art]

 Rolling compaction vehicles are used for compaction and leveling of the ground such as roads, but wheels of different weights such as iron wheels and tires, or a combination of these are used. Conventionally, there is no one vehicle in which wheels are exchanged for use.

[0003]

[Problems to be solved by the device]

 Depending on the condition of the road or other ground to be compacted or grounded, a rolling compaction vehicle having different ground contact pressures is often required in one work. Conventionally, in such a case, multiple vehicles with wheels with different weights were prepared and carried to the work site. However, preparing, transporting, and parking a plurality of different vehicles requires extra labor, time, and money, and reduces vehicle use efficiency and work efficiency. Therefore, an object of the present invention is to obtain a rolling stock vehicle that can cope with various road conditions with a single vehicle.

[0004]

[Means for Solving the Problems]

 In the present invention, the wheels can be exchanged by using a common connecting device in one vehicle, whereby a plurality of wheels having different ground pressures can be appropriately exchanged in one vehicle and used on different roads. We obtained a rolling compaction vehicle that can handle such situations and solved the above-mentioned problems.

In the present invention, the wheel couplings attached to the front and rear portions of the frame have a common mounting device for the front and rear portions of the frame, and this coupling device allows the couplings to be detached from the outside of the vehicle body. It can be attached with a spacer sandwiched between it and the frame.

The wheels may be iron wheels or tires or a combination thereof. The rolling vehicle of the present invention is suitable for use with wheels having a weight of 2.5 to 4 tons, and the width of the iron wheel varies depending on the weight. Therefore, it is possible to attach iron wheels of different weights to the frame by preparing spacers of different thicknesses corresponding to the widths of the iron wheels, and attaching the spacers to the vehicle body by sandwiching them between the coupler and the frame.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The couplers 5 and 6 attached to the wheels 3 and 4 are detachably attached from the outside of the vehicle body by attaching devices 7 and 8 provided on the upper portions thereof. Attached to the front and rear of the two sides. In this embodiment, holes for a plurality of bolts are provided through the mounting devices 7 and 8 and are also provided at corresponding positions of the frame 2 so that the couplers 5 and 6 are attached to the frame 2 by the bolts 8. It has been burned. In this case, the positions of the bolt holes in the front and rear parts of the mounting devices 7 and 8 and the frame 2 are the same at the same position in the front and rear, and the bolts used are of the same standard that conforms to the holes. is important. That is, the couplers 5 and 6 have common mounting devices 7 and 8 on their upper portions, and different wheels can be exchanged and attached to the same vehicle body, or front wheels and rear wheels can be exchanged and attached. .

Wheels include iron wheels 3 and tires 4, and iron wheels having a weight of 2.5 tons to 4 tons are used. A heavy iron wheel has a large width. The width of the iron wheel with the minimum weight matches the width of the car body. When attaching a large width iron wheel to the vehicle body, a spacer 7 having a thickness corresponding to the difference between the vehicle body width and the wheel width can be sandwiched between the coupler 5 and the frame 2 for attachment. Therefore, spacers having thicknesses corresponding to the types of wheels having different widths are prepared in advance.

A bearing 11 is provided below the coupler 5 attached to the iron wheel 3, and the end of the axle 12 of the iron wheel 3 is fitted from the inside.

A lower portion of the coupler 6 attached to the tire 4 extends inward of the vehicle body and is attached to a bracket provided so as to be connected to the center of the tire axle.

【The invention's effect】

 Since the wheel of the present invention has a common mounting device on the upper part of the coupler, the mounting device can be detached from the frame from the outside, and the spacer can be used as a part of the mounting device. Not only can they be exchanged, but iron wheels with different weights and therefore different widths can be exchanged for the same vehicle body at the work site. Further, the combination of the types of wheels can be appropriately changed, such that the front wheels and the rear wheels are iron wheels or tires, and the front wheels and the rear wheels are iron wheels and tires or tires and iron wheels are combined. Therefore, one vehicle can handle various road and ground conditions by exchanging and combining these wheels.
