The invention discloses an underwater test lifting device. The device comprises a mounting platform, a rotary mechanism and a main lifting mechanism. The rotary mechanism comprises a first driving unit, a rotary body and a guide frame. The first driving unit is arranged on the platform board, an opening is formed in the middle of the platform board, one end of the rotary body penetrates through the opening to be in transmission connection with the first driving unit, the guide frame is fixedly connected with the other end of the rotary body, and the guide frame can stretch out and draw back inthe axis direction of the rotary body. The main lifting mechanism comprises a supporting plate, a lifting truss, a hydraulic oil cylinder, a mounting plate and two guide assemblies, wherein the supporting plate is arranged between the rotary body and the guide frame in a clamped mode. The two ends of the hydraulic oil cylinder are fixedly connected with the guide assemblies correspondingly, and the two guide assemblies are arranged on the supporting plate in a sliding mode. The two ends of the lifting truss are correspondingly hinged to the two guide assemblies and are in sliding connection with the mounting plate. The guide frame is fixedly connected with the mounting plate, and the mounting plate is used for mounting equipment to be tested. The underwater test lifting device can improvethe operation stability and precision of the tested equipment.
Description
technical field [0001] The invention relates to the field of underwater test devices, in particular to an underwater test lifting device. Background technique [0002] The underwater test lifting device is used to test the performance and parameters of the test equipment under water. [0003] Existing underwater test device is provided with lifting platform, and lifting platform is located on the deck, is provided with winch on the lifting platform, and winch is used for lifting and lowering lifting rod, and lifting rod is connected with test equipment. There is an opening on the deck, and the test equipment is lowered from the opening to a certain depth underwater by lowering the lifting rod and the lifting platform of the hoist. In addition, a turntable drive mechanism is provided at the lower end of the lifting rod, which can drive the lifting rod to drive the test equipment to rotate for testing. Test equipment such as sonar equipment, the test device can detect the pe...
