The present invention relates to a bridge inspection device for general inspection and repair work carried out in the pier of the various bridges, and in particular, while the worker moves around the bridge for a number of bridges constituting the bridge The present invention relates to a recirculating inspection device that can be inspected.

Most bridges are structured to support the mold of the unit member, which is the upper structure, by the bridge devices by several bridges, so regular inspection and repair work should be done for the safety of bridges.

In order to inspect and repair several bridges, bridge inspection facilities that bring workers closer to the bridges must be installed. There are various types of inspection facilities for bridges provided so far, such as stationary and mobile.

However, most of the inspection facilities provided in the related art have no problem in accessing the pier of the worker, but the facilities cost a lot, and there are disadvantages that are unsightly in appearance.

For example, a stationary inspection facility that can be installed at a relatively low cost may be provided with dozens of brackets of a certain width over the perimeter of the side of the coping, the top of the piers, for each of several piers. It is a configuration that forms an inspection passage where the worker can move by fixing and installing a safety rail. The inspection passage is always secured throughout the pier circumference, so the worker's activity is good. However, in the case of a bridge installed in the downtown area, the pier circumference Support brackets, steel plate scaffolding, and safety railings installed on the floor are unsightly exposed and detrimental to the urban aesthetics. Although the installation cost is somewhat lower than that of the mobile inspection trucks, it is essential for most types of fixed inspection facilities. Dozens of brackets and steel plates for fixed installation around the coping of the piers All railings and the cost of material and sigongbi take the bar when all the material of stainless steel as well as steel, even when (鋼材), including, in the case of steel, even after the installation has had a problem that required a lot of maintenance to the surface coating.

In addition, the configuration of a mobile inspection facility that moves by rail between several bridges throughout the bridge, although there is an advantage that it is easy to move between bridges, as a means for moving between bridges, In addition, the mobile truck should have a self-propelled traveling device, a driving power source, and a driving device, so that the overall cost of the facility was much higher than that of the fixed inspection facility.

SUMMARY OF THE INVENTION The present invention is provided to solve the problems of the conventional bridge inspection facilities as described above, and an object is to provide a circular circulation for a worker around each pier in forming an inspection facility for each of several bridges constituting the bridge. It is to provide a recirculating inspection device that can be inspected while moving on a low cost and has a good appearance after installation and low maintenance cost.

Another object of the present invention is to provide a practical circulating inspection device rail device for forming the circulating inspection device and a traveling device for a circulation cart of the circulation inspection device, respectively.

Another object of the present invention is to provide a removable worktable for a circulating check device that can be detachably installed on a running rail around a pier in the use of the circulating check device to form a temporary fixed workbench.
