Abstract
Description
Technical Field
[0001] This utility model relates to the field of road and bridge bearing testing technology, and is a road and bridge bearing testing device. Background Technology
[0002] Bridge bearings are a key component of bridge structures, connecting the superstructure and substructure (such as piers and abutments). They play a vital role in transferring loads, adapting to deformation, and ensuring the safe operation of the bridge structure. Under the influence of live loads, temperature changes, concrete shrinkage and creep, the bridge will deform (including displacement and rotation). The bearings can adapt to these deformations, ensuring that the actual stress conditions of the superstructure and substructure of the bridge are consistent with the design calculation drawings.

[0048] The testing support mechanism 6 is installed on the side surface of the base 3 and is used for supporting the compressive strength testing of the bridge bearing.
[0049] The testing mechanism 7 is installed on the top side surface of the top plate 2 and is used for the compressive strength testing of the bridge bearing.
[0050] The movable mechanism 4 facilitates the movement of the entire testing device, allowing for easy adjustment and positioning of the testing device at the bridge bearing location. This simplifies the testing operation and makes bridge bearing testing convenient. Before testing, the clamping and adjusting mechanism 5 is activated to clamp and fix the bridge bearing to be tested, raising it.

The slide frame 52 drives the connecting seat 55 to move, and the connecting seat 55 drives the clamp 54 set on the side surface to move, so as to facilitate the adjustment of the position of the clamp 54. Then the cylinder 56 is activated, which pushes the fixedly connected clamp 54 to move, so that the clamp 54 can clamp and fix the bridge support.

The connecting block 62 drives the fixedly connected testing support platform 63 to move, so that the testing support platform 63 can move into the placement slot 64 between the two bases 3. The bases 3 support the support platform, which facilitates the subsequent testing and placement of the bridge bearing.
