Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mobile three-dimensional road mounting device that can be applied to self-propelled road repair vehicles and the like.

(Prior Art) As shown in FIGS. 9 and 10, a conventional mobile multi-level road includes a mobile multi-level road (a dovetail or box-shaped road) 1, 2, which has a slope on an existing road surface 5.
3 and 4 are arranged symmetrically around a repair part 6 on the road, and repair work on the existing road surface can be carried out while allowing automobiles 7 to pass over it without stopping traffic.

However, this mobile elevated road is a base (hangar)
It is not possible to tow the vehicle with a trailer or other similar device for a long period of time, as shown in Figure 9, between the site and the work site (which is thought to be a maximum distance of 20 to 30 km). Therefore, it would be desirable to stack them compactly and tow them, but conventional products were not equipped with an appropriate stacking device.

(Problems to be Solved by the Invention) The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and the low-height parts of mobile elevated roads can be easily stacked and construction work carried out from the base (hangar). The object is to obtain a mobile overpass loading device that can be transported to the site.

(Means for Solving the Problems) Therefore, the present invention provides a mobile multi-level road mounting device comprising a side module, a submodule, a mini module, and a lamp, wherein the side module has wire sheaves at the front and rear parts. A wheel with a wire sheave coaxially mounted on the lower front side of the sub-module, one end of which is wound around a winch provided within the sub-module, and the other end of the cable is attached to the wire sheave provided within the sub-module and the wheel. The mini-module is connected to the rear part of the sub-module by a pin and a hydraulic expansion mechanism, and the mini-module is connected to the rear part of the sub-module by a pin and a hydraulic expansion mechanism. In addition to attaching the wheels, the lamp is attached to the rear of the mini module using a pin.
They are connected so that they can be bent 180 degrees, and when the winch is operated to mount the sub-module on the top of the side module, the mini-module is bent downward so that the bottom surface of the sub-module is almost parallel to the top surface of the side module. The device is designed to be mounted while retaining the components, and is intended to be used as a means to solve the problem.

(Function) First, when mounting the sub module on the upper part of the side module, when the winch is activated and the cable starts to be wound up, the front wheel at the bottom of the sub module starts to climb along the rear end surface of the side module, and at the same time The mini-module begins to bend downward when the hydraulic expansion and contraction mechanism is activated, and eventually the lower front wheels of the sub-module move forward while rolling on the upper surface of the side module. At this time, the mini module should be mounted so that the bottom surface of the sub module is approximately parallel to the top surface of the side module.
While supporting the rear part of the sub-module, the wheels on the lower rear side are rolled to bend the sub-module significantly downward, and when the front wheels of the sub-module are eventually positioned at the upper front end of the side module, the sub-module is mounted at a predetermined position on the side module. . Then, by operating the hydraulic expansion and contraction mechanism so that the mini-module does not hit the rear part of the side module, the mini-module also rests on the upper surface of the side module while keeping the rear side of the sub-module horizontal. In this case, during operation of the mini-module, the lamp is bent 180° and supported by the mini-module.

FIG. 6 shows the process in which the wire 25 is started to be wound by the operation of the winch 18 of the submodule 9.
At the same time, the legs 20 are pulled up, and the hydraulic expansion/contraction mechanism 22 is operated to bend the mini module 10 downward. At this time, the wheels 16 on the lower front side of the sub-module 9 start climbing along the rear end surface 31a while being guided by the guide 30 shown in FIG.
moves forward while rolling on the floor slab surface 31 of the side module, and with the mini module 10 supporting the lamp 11 bent at 180 degrees, the lower surface of the sub-module 9 is almost parallel to the floor slab surface 31 of the side module. While supporting the rear part of the sub-module 9, the wheels 23 on the lower rear side are rolled so that the wheels 23 on the lower side of the rear part of the sub-module 9 are bent sharply downward as shown in FIG.

In this manner, the mini-module 10 is mounted horizontally at the predetermined position shown in FIG. 1 by the operation of the hydraulic expansion/contraction mechanism 22 so that the mini-module 10 does not hit the rear of the side module 8. In addition, in the present invention, wire is used for winding, but
Others (such as chains) may also be used. In addition, when setting the submodule 9 onto the road from above the side module 8, the operation is the reverse of the above-mentioned mounting process.
