[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bogie for a device for inspecting an image of a bridge auxiliary equipment such as a civil engineering equipment of a bridge, telephone, electric power, gas, water supply and the like.

[0002]

2. Description of the Related Art Communication cables and the like are generally laid in underground facilities, bridge facilities, overhead facilities, the sea floor, and the like. Among them, bridge facilities are installed when crossing rivers, seas, lakes and other structures, and their structures are various. In general, a pipeline is attached to the bridge equipment, and a communication cable or the like is laid in the pipeline.

In such bridge installation equipment, it is necessary to periodically inspect and repair the bridge installation equipment in order to maintain safe and reliable communication equipment.

[0004] At the time of this inspection work, there is no problem in the case of a small bridge that allows the operator to directly look at it. However, in general, the boat is floated on the boat and checked using binoculars, or a scaffold is assembled. A visual check was performed. However, these inspections are uncertain, and there are many problems that scaffold assembly takes time and costs.

[0005] Recently, an operator has gotten on a mechanical bucket to perform an inspection, or an image inspection has been carried out by using a bridge installation equipment inspection apparatus using a television camera.

However, in the inspection using a mechanical bucket,
Since the operator carries out inspection work on a bucket attached to a long arm, the size of a work vehicle equipped with a mechanical bucket is increased to 20 tons or more, causing traffic obstacles during inspection work and the cost of the vehicle itself. Is high.

[0007] On the other hand, the bridge inspection equipment inspection device has functions such as rotation, elasticity of the arm, vibration countermeasure, etc. so that the inspection can be performed while moving along a general pedestrian road, and is lightweight and easy to use. There is a lightweight and telescopic arm with an ultra-small zoom TV camera placed at the tip of the arm to inspect the backside and inside of complex structures, and record and inspect necessary parts on a VTR while watching the monitor image at hand. It has a function that can input the situation and the like by voice. As a result, the situation of bolts and nuts and the like at locations that cannot be visually inspected can be confirmed and recorded with images.

[0008] However, the conventional inspection system for bridge attachment equipment is designed to use a general walkway, and therefore cannot be used on a management road with a narrow bridge. Further, the arm itself is composed of two rods, and each rod can be extended and contracted in the longitudinal direction. However, the rod is too short to be used for long bridge inspection, and cannot be used for inspection.

Here, the inspection at the Nagaohashi Bridge will be described.
In general, a long bridge is in a special situation. For example, since an installation place of a bridge attachment facility is at a high place, for example, 30 m to 70 m, it is often impossible to inspect the bridge due to the natural environment. For example,
In winter, there are many risk factors for work such as gusts, so there are many restrictions on the use period of external inspection vehicles owned by the Nagaohashi administrator, and there are periods during which inspection work cannot be performed. In addition, the exterior inspection vehicle owned by the administrator of the Nagaohashi Bridge requires qualification for driving operation, which also limits the period of use. Further, since the structure of the bridge is special in a long bridge, it is difficult for the arm to avoid a girder at a specific distance, and therefore, it is difficult to move the bridge inspection equipment inspection device. In addition, in the case of a long bridge, it is not possible to visually inspect the bridge additional equipment behind the management road. Inspections with scaffolds are difficult to secure and are dangerous.

[0010]

The object of the present invention is to improve the method of moving, assembling, and mounting the inspection system for a bridge additional equipment on a narrow management road of a bridge in order to solve the various problems described above. As well as to ensure safety.

[0011]

SUMMARY OF THE INVENTION The construction of a truck for inspecting a bridge attachment system according to the present invention comprises a bogie main body having a variable width wheel having a rail with a rail at a side end of the bridge, and a side end of the bogie main body. A channel member capable of taking a horizontal state and a vertical state slidably connected to each other by a hinge, an elevating member detachably coupled to the channel member, a vertical member detachably coupled to the elevating member, A horizontal moving member coupled to a vertical member, and a stopper for preventing each of the elevating member and the horizontal moving member from falling are provided.

[0012]

The truck body, the lifting member and the vertical member can be disassembled and transported. When not in use, the channel member is folded into the carriage body. A television camera is attached to the horizontal moving member, and equipment necessary for inspection by images, such as a monitor,
A VTR, a remote control device and the like are mounted. When using a trolley for inspection, align the wheels with the rail of the bridge, and put the trolley body between the rails. On the other hand, the elevating member and the vertical member are combined,
A television camera is attached to the horizontal moving member. In this state, the elevating member is connected to the channel member, the channel member is raised while sliding, and the horizontal moving member is lowered under the bridge, and the necessary equipment is mounted on the bogie main body, and the TV camera and the horizontal moving member are connected. Connect the wiring cord. Then, the handle is rotated to perform vertical movement adjustment, and the horizontal movement member is remotely operated to perform horizontal movement adjustment. In this way, the channel member hinged to the bogie body becomes vertical, and the elevating member and the vertical member follow this channel member, so that the arm protruding horizontally from the bogie body is eliminated, and the elevating member, the vertical member, the horizontal moving member, There is no influence of bending moment due to the load of the TV camera or the like. In addition, since the railing of the bridge is used as a rail, it can be moved even on a narrow management road of the bridge as long as the wheel width is variable, and even if there is any obstacle, it can be moved or transported manually. Can be.

[0025]

[Effects of the Invention] As described above, according to the trolley for inspecting a bridge-attached facility of the present invention, the rail of the management road of the bridge can be easily moved as a rail, so that it can be safely inspected from the management road. Inspection time can be set freely, and operation adjustment is easy. Also, when not in use, the bogie body and the elevating member,
Vertical members can be disassembled and transported. Since the channel member can be rotated and slid with respect to the bogie main body, the channel member can be folded when not in use, and the assembling and mounting of the elevating member and the vertical member can be easily performed during use. In addition, since there is no horizontal arm during use, there is no influence of the bending moment due to the load of the elevating member, the vertical member, the horizontally moving member, the television camera and the like. Furthermore, if the necessary equipment of the bridge installation equipment inspection device is mounted on the bogie body, inspection can be performed, so the status of the installation equipment can be easily checked, and the video at that time is recorded on the VTR to facilitate equipment management. Can be done. In addition, the equipment is divided and imported,
Workability is good because it can be carried out. From the above, it is possible to safely, reliably and easily inspect the auxiliary equipment at the long bridge.
