Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile assembly frame for road repair.

Repairs to paved roads are generally carried out while restricting vehicular traffic, which causes traffic congestion. In order to improve this current situation, we have proposed a mobile assembly structure in which a bridge-like structure is temporarily installed over the area to be repaired, vehicles can pass over it, and the necessary repair work can be carried out at the bottom of the structure. has been done.

As shown in Fig. 12, the conventional structure of this type has a central part a of the bridge that is equipped with a self-propelled device that has a working space inside, and a lamp part that can be placed on the central part of the bridge in a hinged or sliding manner when moving. Many are composed of b.

Generally, in this type of structure, since the vehicle runs on the bridge, the slope of the ramp section cannot be made large, and as a result, the overall length of the structure becomes long. There are two contradictory constraints that impede the work below.

In the conventional frame, the total length of the frame during movement, that is, the length of the central portion a of the frame, must significantly exceed the length permitted for a vehicle, making it difficult to put it to practical use. Furthermore, if the lamp part b is connected to the lamp part b by a hinge type, the hinge part will be twisted when installed on a road with a cross slope, resulting in a weak point in terms of strength.

The present invention has been proposed to solve these problems, and includes an overhang integrally extending to the front end of a road plate supported on a self-propelled truck, and a front end attached to the lower part of the overhang. A pair of central bridging units on which a driver's seat is mounted so as to be movable in the front-back direction, a pair of towable ramp roadbeds that are removably connected to each of the bridging units, and a pair of tractable ramp roadbeds that can be detachably attached to each of the ramped roadbeds. and a bridge ramp section which is connected to the ramp section and is made up of an inclined block incorporating a transfer device for moving onto the same ramp road bed during movement, and by connecting the ends of each overhang section of the pair of bridge units facing each other. The present invention relates to a mobile assembly frame for road repair, characterized in that a bridge central portion is constructed and a work space is formed below the road plates of both units.

In the present invention, as described above, the central part of the frame is composed of a pair of central bridging units in which an overhang part extends to the front end of a road plate supported on a self-propelled truck, and both opposing units By joining the ends of the overhang parts of the body, a working space is secured under the road plate of both units. In addition, since the overhang portion is integrally constructed with the road plate supported on the self-propelled truck, the strength of the road plate is ensured.
Overhang structure is possible. Since the driver's seat is movably mounted in the front-rear direction at the bottom of the overhang that extends integrally to the front end of the road plate of the central bridge unit, the driver's seat that is generated due to the overhang structure is can eliminate poor visibility.

In addition, since the towable slope road base that constitutes a part of the bridge ramp section is removably connected to each central bridge unit, it can be carried in and removed in an orderly manner, and can be assembled and removed in an orderly manner.
Removal work is carried out efficiently.

Furthermore, since a transfer device for the ramp road bed is built into the slope block that is removably connected to the towed ramp road bed that constitutes a part of the bridge ramp section, there is no need to use complicated and large-scale equipment. , slope blocks can be stacked and unloaded on the slope road bed.

Furthermore, in the present invention, since the frame is divided into a pair of central bridge units, a pair of trailing slope roadbeds, and a pair of slope blocks, each divided part can be moved on the road without violating legal restrictions. The present invention has many advantages.
