[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 In this embodiment, a novel rubber fender tilt compression performance test device is provided, including a test box 1, a front observation wall 2 is provided at the front side of the test box 1, a fixed plate 8 is fixedly connected to the middle of the test box 1, an adjustable pressing plate mechanism 5 is slidably connected above the fixed plate 8, the adjustable pressing plate mechanism 5 includes a lifting platform 51, the lifting platform 51 moves up and down inside the fixed plate 8, a driving device is installed on the fixed plate 8 for adjusting the pressing plate mechanism 5 to move up and down, pressing plates 55 are symmetrically provided at both ends below the lifting platform 51, and one end of the pressing plate 55 is rotatably connected to the lifting platform 51;

[0033] The adjusting platen mechanism 5 is lowered by the driving device, and the adjusting platen mechanism 5 is lowered so that the pressing plate 55 is lowered to perform compression test on the test product below.

[0034] The test box 1 has fixed seats 7 on both sides of the fixed plates 8. One end of the fixed seat 7 is located outside the test box 1 and is located outside the test box 1. The test box 1 has lifting mechanisms 9 on both sides of the fixed seats 7. The lifting mechanisms 9 include lifting frames 92 that can move up and down. The lifting frames 92 are used to lift the fenders for compression. The fenders are lifted above the fixed seats 7 by a sling or a forklift, so that the user can push the fenders into the test box 1 to perform a compression test. During the test, the lifting mechanism 9 can rise as the adjusting plate mechanism 5 is lowered, and the fenders are first lifted by the lifting frames 92, so as to avoid the rubber fenders being compressed and pushed away during tilt compression, thereby causing the test to fail.

[0035] In this embodiment, specifically, an adjusting plate 52 is slidably connected to one side of the lifting platform 51, and the adjusting plate 52 is located on the front side of the fixed plate 8. Insertion rods 54 are fixedly connected to both ends of the adjusting plate 52. The insertion rod 54 is inserted into the lifting platform 51. An adjusting screw rod 53 is threadedly connected to the inside of the adjusting plate 52. One end of the adjusting screw rod 53 is inserted into the front side of the fixed plate 8. The adjusting screw rod 53 is slidably connected up and down on the front side of the fixed plate 8. A connecting rod 2 57 is connected below the insertion rod 54, and a connecting rod 1 56 is connected below the lifting platform 51. A pull rod 58 is connected between the connecting rod 1 56 and the connecting rod 2 57. A connecting frame 59 is provided above the pressure plate 55, and both ends of the pull rod 58 are located inside the connecting frame 59. By rotating the adjusting screw rod 1 53, the adjusting plate 52 can be moved away from or close to the lifting platform 51. When the adjusting plate 52 is close to the lifting platform 51, the insert rod 54 is driven to be inserted into the lifting platform 51, and the connecting rod 2 57 under the insert rod 54 is close to the connecting rod 1 56 under the lifting platform 51, so that the pull rod 58 between the connecting rod 1 56 and the connecting rod 2 57 is lifted downward, and the pull rod 58 pushes the pressing plate 55 to rotate downward. Conversely, when the adjusting plate 52 is away from the lifting platform 51, the pressing plate 55 rotates upward, thereby changing the inclination angle of the pressing plate 55, so that the compression test can be performed at different inclination angles during the test.

[0036] In this embodiment, specifically, one end of connecting rod 1 56 and one end of connecting rod 2 57 are both rotatably connected to the top of pull rod 58 , the other end of connecting rod 1 56 is rotatably connected to lifting platform 51 , and the other end of connecting rod 2 57 is rotatably connected to insertion rod 54 .

[0037] In the present embodiment, specifically, the lifting mechanism 9 includes a positioning seat 91, the positioning seat 91 is located on both sides of the fixed seat 7, the lower end of the lifting frame 92 is inserted into the positioning seat 91, the upper end of the lifting frame 92 is concave arc-shaped, the bottom end of the interior of the test box 1 is fixedly connected to a limit plate 94 near one side of the fixed plate 8, and a lifting frame 95 is slidably connected to the limit plate 94, one end of the lifting frame 95 is fixedly connected to a support rod 93, and the support rod 93 is located below the upper end of the lifting frame 92, and a movable groove 97 is opened at the upper end of the lifting frame 95, and a rotating rod 96 is rotatably connected to one side of the fixed plate 8, and one end of the rotating rod 96 is located inside the movable groove 97, and a connecting plate 510 is fixedly connected to one side of the pressing plate 55 below the lifting platform 51, and the lower end of the connecting plate 510 is located above the other end of the rotating rod 96. When the lifting platform 51 is lowered to drive the pressing plate 55 to descend and compress, the connecting plate 510 first descends to rotate one end of the compression rotating rod 96 downward, and the other end of the rotating rod 96 pushes the lifting frame 95 to rise. The movable groove 97 makes the lifting frame 95 not need to move horizontally, and the lifting frame 95 thus rises vertically under the restriction of the limit plate 94. The support rod 93 at one end of the lifting frame 95 drives the lifting frame 92 to rise, and the lifting frame 92 lifts the fender above the fixing seat 7. The lifting platform 51 continues to descend to perform an inclined compression experiment on the fender. The lifting frame 92 can be replaced and adjusted according to different arc-shaped outer contours.

[0038] In this embodiment, specifically, the connecting plate 510 and the lifting frame 95 are located on different vertical planes. When the connecting plate 510 descends, it will not press onto the lifting frame 95.

[0039] In this embodiment, specifically, an observation mechanism 3 is installed on the front observation wall 2, and the observation mechanism 3 includes a moving plate 31 and a marking plate 32. The marking plate 32 passes through the front observation wall 2 longitudinally, and one end of the marking plate 32 is located inside the test box 1 and is fixedly connected with the marking plate 32. The marking plate 32 can fit the rubber fender, and a plurality of scales are provided on the moving plate 31. The marking plate 32 is pushed outward by the deformation of the rubber fender, and the marking plate 32 drives the moving plate 31 to move. Through the change in the length of the moving plate 31 exceeding the front observation wall 2, the deformation amount of the fender is intuitively detected.

[0040] In this embodiment, specifically, a limiting mechanism 6 is provided inside the test box 1 at the rear side of the fixed plate 8, and the limiting mechanism 6 includes an adjusting screw rod 2 61 and a baffle 62. The adjusting screw rod 2 61 spirally passes through the rear side of the test box 1, and one end of the adjusting screw rod 2 61 is rotatably connected to the baffle 62. The baffle 62 is located inside the test box 1, and the baffle 62 is longitudinally slidably connected to the test box 1. By rotating the adjusting screw rod 2 61, the adjusting screw rod 2 61 is screwed into or out of the test box 1, and the adjusting screw rod 2 61 drives the baffle 62 to move together. Before the compression test, one end of the fenders on both sides can be pushed to align, which is convenient for subsequent observation and comparison.

[0041] In this embodiment, specifically, the driving device includes a motor 4, which is fixedly mounted above the test box 1, and a reduction box is provided between the motor 4 and the test box 1. The motor 4 is connected to a lifting screw 41 through the reduction box, and the lifting screw 41 spirally passes through the lifting platform 51, and the lifting screw 41 is rotatably connected to the fixed plate 8. When the motor 4 is started, the motor 4 drives the lifting screw 41 to rotate after being decelerated by the reduction box, and the lifting screw 41 thereby drives the lifting platform 51 to rise or fall for compression.

The transparent material facilitates observation, and the front observation wall 2 is slidably connected to the test box 1, so that the front observation wall 2 can be removed for maintenance and adjustment.
