DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0016] See also Figure 1-3 , an impact resistance testing device for a speedboat, comprising a test frame 1, wherein a first rotating shaft 2 and a second rotating shaft 4 are rotatably arranged in the vertical direction in the test frame 1, a first gear plate 3 is mounted on the first rotating shaft 2, a second gear plate 5 is mounted on the second rotating shaft 4, the first gear plate 3 and the second gear plate 5 are connected by a transmission chain 6, a lifting block 10 is mounted on the transmission chain 6, sleeves 11 are mounted at both ends of the lifting block 10, two symmetrically distributed limiting rods 12 are mounted in the test frame 1 and are slidably connected to the sleeve 11, the sleeve 11 is fixedly connected to a supporting platform 13 for storing the speedboat to be tested, and further comprising: A driving component, which is installed at the bottom of the test stand 1 and connected to the second rotating shaft 4, and is used to drive the second rotating shaft 4 to rotate and drive the transmission chain 6 to transmit; A push-out component, which is disposed in the supporting platform 13 and is used to push out the assault boat to be inspected on the supporting platform 13 so that it falls from a high altitude; A transmission component is arranged between the test stand 1 and the pushing component, and is used to drive the pushing component.

[0017] A protective cover 24 is installed at the bottom of the test frame 1, and a movable door 25 is arranged on the outer side of the protective cover 24, wherein the protective cover 24 is used to protect the surroundings of the assault boat when it collides and impacts, to prevent the fragments generated by the collision from splashing and accidentally injuring the test personnel, and the assault boat in the protective cover 24 can be taken out through the movable door 25.

[0018] By placing the assault boat to be tested on the pushing component of the supporting platform 13, the driving component drives the second rotating shaft 4 to rotate, thereby driving the second gear plate 5 to rotate, and the second gear plate 5 can drive the transmission chain 6 for transmission, and the lifting block 10 is driven to rise by the transmission chain 6. Under the action of the limit rod 12 and the sleeve 11, the supporting platform 13 will be steadily raised. When the supporting platform 13 is raised to a certain height, the transmission component will drive the pushing component to push the assault boat on the supporting platform 13, so that the assault boat will fall freely from the supporting platform 13. The fallen assault boat will fall into the protective cover 24 and collide with the bottom of the test frame 1, so as to detect the impact resistance of the assault boat. In addition, the height of the free fall of the assault boat can be adjusted by controlling the height of the transmission component driving the pushing component, and then the impact force on the assault boat caused by the collision can be adjusted, and the use effect is better.

[0019] In one case of this embodiment, the driving component includes a motor 9 installed at the bottom of the test frame 1 , a second bevel gear 8 is installed at the output end of the motor 9 , and a first bevel gear 7 meshing with the second bevel gear 8 is installed on the second rotating shaft 4 .

[0020] When the transmission chain 6 is needed to transmit, the motor 9 is started, and the second rotating shaft 4 is driven to rotate through the meshing first bevel gear 7 and the second bevel gear 8, so that the second gear plate 5 rotates, and the first rotating shaft 2 and the first gear plate 3 can drive the transmission chain 6 to transmit, and then drive the lifting block 10 to lift and lower, thereby realizing the lifting and lowering of the supporting platform 13.

[0021] In one case of this embodiment, the ejection component includes a conveying groove 14 opened in the supporting platform 13, and a third rotating shaft 15 and a fourth rotating shaft 17 are rotatably arranged in the conveying groove 14. A first conveying wheel 16 is installed on the third rotating shaft 15, and a second conveying wheel 18 is installed on the fourth rotating shaft 17.

A vertical rack 23 is installed on the side of the mounting block 22 facing the transmission chain 6.

[0023] When the supporting platform 13 rises to a certain height, the matching gear 20 at the end of the third rotating shaft 15 will mesh with the vertical rack 23, thereby driving the third rotating shaft 15 to rotate, causing the third transmission wheel to rotate, and cooperating with the fourth rotating shaft 17 and the second transmission wheel 18 to drive the conveyor belt 19 for transmission, so that the conveyor belt 19 can push the speedboat on the supporting platform 13 out of the supporting platform 13 to make it fall freely. In addition, the height of the mounting block 22 can be adjusted by the hydraulic rod 21, thereby changing the height of the vertical rack 23, that is, changing the height to which the speedboat on the supporting platform 13 is pushed out, and then the impact force generated by the collision on the speedboat can be adjusted, and the use effect is better.

[0024] The present invention places the assault boat to be tested on the pushing component of the supporting platform 13, drives the second rotating shaft 4 to rotate through the driving component, thereby driving the second gear plate 5 to rotate, and cooperates with the second gear plate 5 to drive the transmission chain 6 for transmission, and drives the lifting block 10 to rise through the transmission chain 6. Under the action of the limit rod 12 and the sleeve 11, the supporting platform 13 will be steadily raised. When the supporting platform 13 is raised to a certain height, the transmission component will drive the pushing component to push out the assault boat on the supporting platform 13, so that the assault boat will fall freely from the supporting platform 13. The fallen assault boat will fall into the protective cover 24 and collide with the bottom of the test frame 1, so as to detect the impact resistance of the assault boat.
