Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, and in particular to a load-bearing inspection device for steel structure bridges. Background Technology

[0002] Steel structure bridges are bridges constructed using steel structures. Generally, bridges with more than 50% steel usage are called "large steel structure bridges." Their main body is made of alloy steel, and the components are manufactured, then assembled and welded. This is a relatively fashionable and modern bridge construction method.

[0003] Existing methods for load-bearing testing of steel bridges typically involve driving standard-load vehicles on the bridge deck in a specific arrangement and along a designated route. This method is inefficient and, in case of accidents, could cause vehicles to fall off the bridge, endangering public safety and negatively impacting bridge construction and inspection. To address the shortcomings of existing technologies, we propose a load-bearing testing device for steel bridges. Utility Model Content

A third hydraulic rod is mounted in the middle of the front end of the rotating rod. A pressure plate is provided at the lower end of the rotating disk. Two sets of telescopic frames and one set of electric actuators are provided on both sides of the pressure plate. The electric actuators are located between the two sets of telescopic frames. Extension plates are provided at the ends of the two sets of telescopic frames and the electric actuators on both sides. A gear ring is provided inside the mounting plate at the lower end of the rotating disk. A transmission gear is provided on the side wall of the gear ring.

[0007] Preferably, two sets of wheels are provided on each of the two side walls of the frame, and two sets of fixing blocks are provided on the other two side walls of the frame. A hydraulic rod is provided in the middle of each of the four sets of fixing blocks, and a gasket is provided at the lower end of each of the four sets of hydraulic rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the telescopic arm, the No. 3 hydraulic rod, and the pressure plate can detect the load-bearing capacity of the bridge deck from the outside, making the detection process safer. It can also detect specific points on the bridge deck, making the detection results more accurate. The telescopic arm can adjust the length and position of the pressure plate, and the rotating disk can adjust the lateral position of the pressure plate to detect the load-bearing capacity of different points on the bridge deck. Furthermore, the extension plate, telescopic frame, and electric push rod can extend the area of ​​the pressure plate and adjust the pressure of the device on the bridge deck, making the detection operation more accurate.

[0014] 2. In this utility model, the worm gear and worm can make the rotating block and telescopic arm more stable during rotation. Due to the unidirectional transmission characteristic between the worm gear and worm, the torque generated by the weight of the rotating block acts on the worm gear and worm, and will not act on the No. 3 motor, making the rotating block more stable and preventing it from easily rotating in the middle of the rotating base due to its own weight. The No. 1 hydraulic rod and shim can keep the frame stable, so that the frame can keep the device stable during the testing process. Attached Figure Description
