Description

Technical Field

[0001] The utility model belongs to the field of fender oblique pressure testing equipment, in particular to a fender oblique pressure testing fixture and fender oblique pressure testing equipment capable of squeezing fenders at different inclination angles. Background Art

[0002] In order to avoid a hard collision between the hull and the port when the ship is docked, it is necessary to install a flexible fender on the side of the hull to provide a buffering effect when the ship is docked, so as to avoid a hard collision between the hull and the port. At present, fenders are mostly replaced by tires, that is, tires are evenly spaced around the outer periphery of the hull to play a buffering role, but their appearance is poor. At present, polyurethane materials have good expansion and contraction properties, such as Figure 1 As shown, the existing fender 5 made of polyurethane material is a straight strip and cylindrical member (with an inner hole 52 in the middle), and the cross-section of the fender is a plane on one side (the side is the mounting surface 51, and the mounting surface 51 fits with the hull when the fender is installed on the hull), and the other side is an arch surface. When the polyurethane fender is subjected to the oblique pressure test, a fixture is required to change the angle of the polyurethane fender and ensure that the fender will not slip at different slopes. At present, the test is based on small sheets of fenders, which cannot well reflect the performance of the large polyurethane fender itself. Therefore, it is necessary to perform a compression test on the fender itself. The horizontal compression test of the fender can use a normal compression fixture. If the fender is subjected to an oblique pressure test, due to the large style of the fender, the angle cannot be well controlled by the fender itself, and no relevant tilt test fixture has been reported.

Among them, each of the extrusion heads 1 also includes a mounting seat 12, and the two mounting seats 12 are horizontally arranged and spaced apart up and down. The two extrusion heads 1 are respectively installed on the side of the corresponding mounting seat 12 close to the other mounting seat 12 through the inclination adjustment member 13. The two mounting seats 12 move to be close to each other or away from each other to drive the two extrusion seats 11 to move to be close to each other or away from each other. Its structure is simple, so that the mounting seat can be used as the installation position of the inclination adjustment member, and the mounting seat moves vertically under the action of external force to extrude or release the fender.
