Description

Technical Field

[0001] This utility model pertains to auxiliary tools for bridge health inspection, specifically relating to a walking device that can be used for bridge inspection. Background Technology

[0002] Many testing devices are needed in the construction, daily maintenance, and health inspection of bridges. For example, ultrasonic instruments are used for flaw detection, using high-frequency ultrasonic waves to detect internal defects (such as cracks and holes) in concrete or metal, and the location of defects is located by analyzing the sound wave reflection signals. Alternatively, radar rangefinders or levels are used to observe the overall condition of the bridge. However, whether in the construction phase or in the subsequent inspection process, we find that this operation has many inconveniences. For example, the use of ultrasonic detectors requires manual holding and fixing, and the deployment of probes at the inspection position also requires the use of coupling agents to fill gaps or to lay cables. Therefore, the inspection process requires the handling of a lot of equipment, and the detection tubes connected to the probes are messy to store and store. Utility Model Content

[0003] The present invention aims to provide a walking device that can be used for bridge inspection, so as to solve the many inconveniences and other problems in the inspection process mentioned in the background art.

[0004] The technical solution is a walking device for bridge inspection, comprising a base plate equipped with walking wheels and a top plate for fixing bridge inspection equipment. The base plate and the top plate are connected by a height adjustment component, which is detachably connected to the top plate and the base plate, including by snap-fit ​​or threaded stud connection. The bottom of the top plate is equipped with detachable walking wheels, allowing the top plate to walk independently when separated from the height adjustment component.

[0005] The top plate is equipped with a mounting base for fixing bridge inspection equipment.

[0006] Furthermore, the outer side of the mounting base is a winding groove, and the mounting base is a magnetic base. The device is fixed by fixing the magnetic absorbing piece to the bottom of the bridge detection equipment.

[0007] The height adjustment component includes an inner sleeve rod and an outer sleeve rod, which are nested together and then inserted into the positioning hole by fastening bolts to achieve height adjustment and fixation.

[0008] At least one notch exists on the top plate and the bottom plate, which can be used to fix the inspection pipe or cable of the bridge inspection equipment.

[0009] The wheels are fixed by screwing studs into threaded holes on the bottom or top plate.

[0010] Furthermore, the connection between the height adjustment component and the top and bottom plates includes a fixing lug, which, in conjunction with screws, secures the bottom of the outer sleeve rod and the top of the inner sleeve rod to the bottom and top plates, respectively.

[0011] Furthermore, the device includes bridge inspection equipment, including ultrasonic detectors, radar rangefinders, level detectors, and infrared thermal imagers, used during inspection.

[0012] Beneficial effects: The device described in this utility model facilitates the operation of bridge inspection equipment, providing a fixed operating platform (top plate) for the equipment, and also allowing for height adjustment, which is more convenient for horizontal inspection or radar ranging. Finally, both the top and bottom plates can be disassembled to create two trailers when not in use, improving the transportability of the bridge inspection equipment. Addressing the problems of cumbersome cable winding and difficult operation when placing inspection tubes (cables with inspection probes) in existing ultrasonic testing instruments, this utility model features a cable storage groove, improving the convenience of cable placement.
