The invention discloses a concrete strength detection device for road and bridge construction, and belongs to the technical field of concrete strength detection.The concrete strength detection device comprises a main body frame assembly, a self-centering transmission structure, a strength detection assembly, a pressing position adjusting mechanism and a centering adjusting structure, and the self-centering transmission structure is arranged on the side face of the main body frame assembly. By arranging the self-centering transmission structure, the strength detection assembly and the centering adjustment structure, centering of concrete samples with different sizes and different shapes is automatically completed in the process of carrying out compression resistance detection on the concrete samples, and it is ensured that the centers of the samples are aligned with the center of the rotating block; therefore, the accuracy and the reliability of a concrete sample detection result are greatly improved, and the problems that an existing concrete strength detection device cannot complete self-centering of a concrete sample, manual operation is still needed, alignment of the center position of a cubic sample and the center position of an extrusion plate cannot be guaranteed, and the accuracy and the reliability of the detection result are influenced are effectively solved. And the accuracy and the reliability of a detection result are influenced.

The invention relates to the technical field of three-way catalyst shell detection, and discloses a method for detecting a three-way catalyst shell, which comprises the following steps: step 1, pretreatment; step 2, mounting; step 3, guiding; step 4, fixing; and step 5, detecting. The air cylinder body drives the swing arm at the output end to swing, the swing arm drives the guide arm at the tail end to turn over through the synchronizing shaft, then the guide arm can be located on the two sides of the connecting position of the three-way catalyst shell finally, the position of the three-way catalyst shell can be adjusted conveniently in the follow-up process, and after the swing arm rotates to the top to make contact with the pressing plate, the guide arm can rotate. The pressing plate extrudes and moves upwards to drive the sliding cover at the tail end to slide towards the center of the outer cover through the rocker arm, the position of the synchronizing shaft on the sliding cover changes, the synchronizing shaft pulls the guide arm to be close to the center as a whole, the three-way catalyst shell in the center is extruded and guided, and it is guaranteed that the three-way catalyst shell can automatically move to the designated clamping position; manual adjustment is not needed, and the whole operation is simpler.

The utility model relates to a kind of panel fixing device, including tray and fixed mechanism, tray is used to support panel, and the two edges of panel along first direction have non-coating area;Fixed mechanism, a set of fixed mechanism is equipped with every non-coating area on tray, each set of fixed mechanism includes pressing plate, adsorption structure and locking structure, the length of pressing plate extends along second direction, adsorption structure is installed in the side of pressing plate towards tray, pressing plate can be moved to the non-coating area of panel or move to completely stagger with panel, when pressing plate moves to the non-coating area of panel above, adsorption structure can be fixed with non-coating area adsorption, the two ends of pressing plate along second direction exceed the edge of panel and can be respectively through a set of locking structure and tray detachably connected, first direction and second direction are arranged at angle setting.The panel fixing device of the utility model can stably fix panel on tray, and will not shield the coating area of panel.
