The invention discloses a low-cycle repeated loading test device which comprises a track platform, an inner hinge frame, a connecting piece, a bearing platform, a loading mechanism and a reaction frame, wherein one end of the inner hinge frame is hinged to the lower surface of the bearing platform, the other end of the inner hinge frame is hinged to the track platform, the connecting piece is used for installing the track platform below the bearing platform, and the loading mechanism is fixedly arranged on the reaction frame. The upper surface of the bearing platform is used for placing a test piece, and the loading mechanism abuts against the upper end of the test piece. According to the low-cycle repeated loading test device disclosed by the invention, the test piece is placed on the bearing platform, the bottom of the inner hinge frame slides on the track platform, and the height of the bearing platform is reduced or increased, so that the height of the test piece is reduced to meet the test height requirement, and after the height of the test piece is adjusted, the height position of the bearing platform is fixed; the test conditions can be applied to the test piece through the loading mechanism and the reaction frame, the test piece test purpose is achieved, and adjustment is convenient by changing the connecting position of the inner hinge frame supported below the bearing platform and the track platform.

The invention relates to a rapid decompression test device comprising a thermal vacuum box (1), a container (2), a gas circuit connection system (3), negative pressure gauges (4), a ball valve (5), a vacuum pump (6), a negative pressure sensor (7), a connection hose (8) and a pin puller (9). The rapid decompression test device is characterized in that interior pressure of a test box is decreased to a specified pressure by pumping through the thermal vacuum box (1), the interior pressure of the container is decreased to the specified pressure by pumping through the vacuum pump (6), a piston on the container is unlocked with the pin puller (9) which runs quickly and highly synchronously, and the piston is opened by the interior and exterior pressure difference so as to allow rapid decompression.

The invention discloses a driving mechanism used on a dragline endurance test platform. The driving mechanism comprises a supporting frame, a turnplate which is connected with the supporting frame in a rotation manner through a first rotor shaft, a mounting hole which is formed in the turnplate and is used for connecting one end part of a drive rod, a motor and a speed reducer for driving the first rotor shaft to rotate, a sliding block fixedly connected with the other end part of the drive rod, a guide rail arranged on the supporting frame, a dragline mounting rack fixedly connected with the sliding block as well as a driving optical shaft arranged on the dragline mounting rack, wherein the mounting hole is deviated from the first rotor shaft, and the sliding block is arranged on the slide guide in a sliding manner; the sliding direction of the sliding block is perpendicular to an axial line direction of the first rotor shaft, the motor drives the turnplate to rotate, and then the drive rod is arranged in the mounting hole of the deviation rotating center; the drive rod can do reciprocating linear motion, and the drive rod drives the sliding block do reciprocating linear motion and further drives the dragline mounting rack to do reciprocating linear motion; therefore, the purpose of a test is achieved, the structure is simple, the use is safe, and a test effect is better.

The invention discloses a common mechanical press wet-type clutch universal test tooling. A bearing and an upper cover II are mounted on a support, an upper cover I is mounted on a big support plate, two T-shaped grooves II are formed in a platform, the support is mounted on the platform, and an expansion sleeve and an adjusting sleeve are sequentially mounted on the inner side of the bearing on the support; a big bushing is further mounted on the inner side of the big support plate, and a panel is welded in the contact position of the lower part in front of the big support plate and a flywheel seat; two small support plates are arranged in front of the big support plate, each small support plate is provided with a T-shaped groove I, a motor pulling plate and two motor sliding plates are mounted between the two small support plates, the motor pulling plate and the motor sliding plates are mounted on the small support plates, the motor pulling plate and the motor sliding plates adjacent to the motor pulling plate are connected together through two adjusting screw rods, and a motor is mounted on the two motor sliding plates. According to the invention, tests can be performed on various types of mechanical press wet-type clutches, and the tooling is not needed to be replaced frequently due to different types of the mechanical press wet-type clutches.
