Description

Technical Field

[0001] The utility model relates to the technical field of road construction detection, in particular to a highway bridge bearing capacity detection device. Background Art

[0002] In the construction of highway bridges, the load-bearing capacity of highways and bridges plays a vital role in driving safety. The longer the highway bridge is in use, the more likely it is to bend and crack. Therefore, before the construction of the highway bridge project begins, it is generally necessary to conduct a load-bearing capacity test on the prefabricated road panels to predict the compressive strength of the highway bridge pavement after completion. At the same time, safety hazards that may exist after the highway bridge is put into use can be discovered in advance.

[0003] A search of existing Chinese patents reveals a device for testing the bearing capacity of highway bridges (Announcement No. CN219475210U) that includes a base with side panels fixedly connected to its upper surface. Threaded rods are rotatably connected to the inner walls of both sides of the side panels. Sliding blocks are sleeved onto the surface of the threaded rods, and one end of the sliding blocks is fixedly connected to a clamping block. This arrangement of threaded rods, clamping blocks, and other structures allows for testing samples of varying sizes. A belt drives a transmission wheel, which in turn drives the connecting rod and second gear, thereby driving the first gear and ultimately the threaded rod, demonstrating its practical value.

[0004] Although the above patent is equipped with a threaded rod, a clamping block, a connecting rod, and a double-layer wheel, and can adapt to the detection of samples of different sizes and has certain practical value, the device can only detect horizontal road surfaces and is not suitable for the detection of complex road conditions such as ramps. It is not convenient for users to use. For this reason, we propose a highway bridge bearing capacity detection device. Utility Model Content
