In addition, each leg section 17 of the respective out-triggers 15 and 16 is made capable of being telescopic vertically and laterally with respect to a truck body. And a wheel 18 driven by a motor 19 is arranged at the lower section of each leg 17, and a worm gear 20 capable of being steered is also arranged onto the upper section of each leg.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a self-propelled outrigger device, and more particularly to a self-propelled outrigger device that can be attached to a working equipment unit that is removably loaded on the chassis frame of a truck.

[Conventional technology and issues]

A conventional working equipment unit loading truck has a structure in which one type of working equipment unit 1 is fixed to a chassis frame of a base 1 and a rack 2, as shown in FIG. Therefore, this working equipment unit loading truck has the following problems.

■ The working equipment unit 1 fixed to the chassis frame of the mother truck 2 cannot be easily replaced with another working equipment unit according to the content of the work at the work site.

■ When working at very low speeds (speeds that match the work), conventional trucks cannot provide stable and sufficient traction even when the accelerator is released (for example, when working with a road cutter), making it difficult to perform the work. It was impossible.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a self-propelled outrigger device having the following structure to which a working device unit can be attached.

That is, the self-propelled outrigger device according to the present invention includes an outrigger frame to which a desired working device unit can be mounted on the upper surface, and a front wheel/outrigger or a front crawler/outrigger attached to the front and rear parts of the outrigger frame, respectively. and a rear wheel/outrigger or a rear crawler/outrigger, and the self-propelled outrigger device is configured to be removably loaded on the rear chassis frame of a parent truck, wherein the front wheel/outrigger or the front The legs of the crawler/outrigger, the rear wheel/outrigger, or the rear crawler/outrigger are extendable and retractable vertically or diagonally, and the front wheel/outrigger, the front crawler/outrigger, and the rear wheel/outrigger are capable of expanding and contracting in the vertical direction or diagonally. Alternatively, a wheel or a crawler is attached to the lower end of the leg of the rear crawler/outrigger so that it can be driven hydraulically, so that it can be detached from the base truck by itself and can travel even when loaded on the base truck. It is characterized by the fact that

Further, the legs of the front wheel/outrigger, the front crawler/outrigger, the rear wheel/outrigger, or the rear crawler/outrigger may be extendable and retractable in the width direction of the vehicle body of the base truck, and the lower ends of these legs The wheels or crawlers attached to the can also be hydraulically steerable.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of self-propelled ARA 1 to RIGA equipment to which a working device unit can be attached according to the present invention will be described below with reference to FIGS. 1 to 4.

In FIGS. 1 and 2, 11 is the mother truck, 12
1 is a working device unit, and 13 is a self-propelled outrigger device to which the working device unit according to the present invention can be attached.

The self-propelled outrigger device 13 includes an outrigger frame 14, a front wheel/outrigger 15, and a rear wheel/outrigger 16, and is configured to be removably loaded on the chassis frame of the base truck 11.

Mounting bolt holes, slits, etc. are pre-processed on the upper surface of the outrigger frame 14 so that a desired working device unit 12 can be mounted thereon. Front wheel and outrigger 15
A rear wheel/outrigger 16 is mounted at the front and rear of the outrigger frame 14, respectively.

The leg portions 17 of the front wheel/outrigger 15 and the rear wheel/outrigger 16 are extendable and retractable in the vehicle width direction of the mother truck 11, as shown in FIGS. 2 and 3. However, these leg portions 17 may also be constructed so that they do not expand or contract in the width direction of the vehicle body.

Further, a hydraulic cylinder (not shown) is disposed at the upper part of the leg portion 17, thereby allowing the leg portion 17 to expand and contract in the vertical direction or in the diagonal direction. Wheels 18 are attached to the lower ends of the legs 17, respectively, and the wheels 18 can be driven by wheel motors 19 directly connected thereto. Further, the wheel 18 is attached so as to be steerable by a worm gear 20 or a hydraulic cylinder installed on the upper part of the leg part 17. However, the wheels 18 can also be constructed so as not to be steerable.

Further, a wheel chock 21 can be attached to the wheel 18, and this wheel chock 21 is used by being interposed between the wheel 18 and the ground when the self-propelled outrigger device 13 is used as an outrigger. Ru.

Reference numeral 22 in FIG. 1 is a driving engine for driving the self-propelled outrigger device 13. As shown in FIG.

Since the self-propelled outrigger device 13 is configured as described above, it can be detached from the base truck 11 by itself and can travel even when loaded on the base truck 11. When the vehicle is loaded on the mother truck 11 and travels, the transmissions 1 to 1 of the mother truck are in neutral or the engine is stopped.

In addition, the self-propelled outrigger device 13 has an outrigger frame 14.
Various working equipment units 12 are attached to the top surface and loaded onto the base truck 11, and if necessary, each assembly of the self-propelled outrigger device 13 and the working equipment unit 12 can be replaced with a desired one. This makes it possible to transport and work with it.

In the embodiments shown in FIGS. 1 to 3, wheels and outriggers 15 and 16 are attached to the lower ends of the legs 17, but as shown in FIG. It is also possible to use a crawler/outrigger 23 instead.

Effects of the Invention Since the self-propelled outrigger device according to the present invention to which a working device unit can be attached is configured as described above, it has the following effects.

■The working equipment unit loaded on the base truck can be easily replaced with another working equipment unit that matches the work content at the work site.

■The optimum vehicle speed required for the work equipment unit can be obtained.
