The application relates to the technical field of bridge load experiment, in particular to a bridge bearing capacity dynamic load experiment detection device. The top end of a supporting frame is fixedly connected with a photosensitive assembly and a first laser range finder. A heavy-load vehicle is provided with a reflector plate, the first laser range finder is horizontal to the reflector plate, the first laser range finder can measure the horizontal distance a from the center of the hub in the tire through the reflector plate, the front and rear hubs of the heavy-load vehicle are both provided with positioning plates through bolts, one end of each positioning plate is fixedly connected with a connecting shaft, the outer side of the connecting shaft is rotatably connected with first shaft sleeves through bearings, and the two first shaft sleeves are connected with an extension rod. The monitoring mode can avoid installing sensors at various positions of the bridge, saves the equipment and the installation amount, and can realize continuous deflection monitoring. In the application, the axle height curve obtained when the heavy-load vehicle advances is compared with the axle height curve obtained when the heavy-load vehicle advances without load.

The application relates to a high-melting-point isotope nuclear target mounting base and a mounting method thereof, the mounting base comprising an insulating base, a high-voltage electrode disc and a nuclear target seat, the insulating base is in a cylindrical shape, an outer track groove is formed in the top of the sidewall of the insulating base, and a through hole is formed in the sidewall of the insulating base; the high-voltage electrode disc is in a cylindrical shape and is sleeved in the insulating base; an inner track groove is formed in the top of the sidewall of the high-voltage electrode disc, a high-voltage connector hole is formed in the sidewall of the high-voltage electrode disc, and a high-voltage connector is inserted into the high-voltage connector hole through the through hole; the nuclear target seat is used for mounting a nuclear target and a graphite pot, and the nuclear target seat is slid into the high-voltage electrode disc through the outer track groove and the inner track groove; the nuclear target seat can be put into or taken out of the high-voltage electrode disc along the outer track groove and the inner track groove, so that the isotope material and the nuclear target can be conveniently mounted, the mounting workload of the isotope material and the nuclear target is reduced, the operation is simplified, and the preparation period of each batch of high-melting-point isotope nuclear targets is reduced.
