Description

Technical Field

[0001] The present invention relates to the technical field of impact experience devices, and in particular to a safety shoe impact experience device. Background Art

[0002] An anti-smashing shoe is a safety shoe designed for special occupations. Its main function is to provide effective protection for workers or personnel who need to protect their feet. Such safety shoes generally have the following characteristics: a hard toe cap that can effectively resist the impact of foreign objects; a non-slip sole design that can increase walking stability.

[0003] When the existing safety shoes are in use, most of them are directly worn. Before wearing, no simulated anti-collision experiment is carried out on the safety shoes, resulting in workers being unable to directly feel the protective performance of the safety shoes. When conducting simulated experiments, most of them are just randomly picking up iron balls by hand to hit the safety shoes. When the safety shoes are hit, they are prone to displacement. At the same time, the release height of the iron balls cannot be quickly and accurately adjusted according to the experience needs, resulting in the anti-smashing performance of the safety shoes not being accurately tested and experienced.

[0004] Therefore, in view of the problem that most of the above-mentioned safety shoe impact experience devices randomly pick up iron balls by hand to hit the safety shoes, the safety shoes are prone to displacement when being hit, and at the same time, the release height of the iron balls cannot be quickly adjusted according to the experience needs to simulate different height impact situations, a safety shoe impact experience device can be designed. Summary of the Invention

[0005] In order to overcome the problems that most of the traditional safety shoe impact experience devices randomly pick up iron balls by hand to hit the safety shoes, the safety shoes are prone to displacement when being hit, and at the same time, the release height of the iron balls cannot be quickly adjusted according to the experience needs to simulate different height impact situations.

[0006] The technical solution is as follows: A safety shoe impact experience device includes a bottom plate. A protective fence is installed at the upper end of the bottom plate. An adjustment and clamping component for fixing the position of the safety shoe is installed at the center of the upper end of the bottom plate. A placement plate for stably placing the safety shoe is installed at the upper end of the adjustment and clamping component. A protective support plate is fixedly connected to the upper end of the protective fence. A pressure-bearing support rod is fixedly connected to the inner side of the protective support plate. A connecting block is fixedly connected to the inner side of the pressure-bearing support rod. An outer steel pipe is fixedly connected to the inner side of the connecting block. An elevating adjustment component capable of adjusting the dropping and impacting height is provided at the upper end of the outer steel pipe. The elevating adjustment component includes an inner adjustment steel pipe that slides inside the outer steel pipe. A limit elevating plate is fixedly connected to the upper end of the inner adjustment steel pipe. A baffle is slidably connected to the upper end of the limit elevating plate. An iron ball that can freely fall to hit the toe cap of the safety shoe and simulate the experience of hitting the foot is placed at the upper end of the baffle.

[0007] Furthermore, a protective outer cover is fixedly connected to the upper end of the placement tray. A placement cavity is provided inside the protective outer cover. A placement platform is fixedly connected to the midline of the placement tray. An adjustment moving slot is penetrated and provided inside the placement tray.

[0008] Furthermore, the adjustment clamping assembly internally includes a protective outer frame plate installed at the center of the upper end of the bottom plate. A driving motor is installed on one side of the protective outer frame plate. A bidirectional lead screw is installed at the output end of the driving motor. Two moving sleeve blocks are threadedly connected to the outer side of the bidirectional lead screw.

[0009] Furthermore, a limit moving block is fixedly connected to the upper end of the moving sleeve block. An arc-shaped moving plate is fixedly connected to the upper end of the limit moving block. A fixed pressing plate is installed inside the arc-shaped moving plate.

[0010] Furthermore, a compression-resistant support plate is fixedly connected to the inner side of the fixed pressing plate. A clamping side plate is fixedly connected to the inner side of the compression-resistant support plate. A buffer soft pad is installed inside the clamping side plate.

[0011] Furthermore, a lifting chute for facilitating the sliding of the inner adjustment steel pipe is provided inside the outer steel pipe. Vertical sliding strips are fixedly connected to both sides of the inner adjustment steel pipe. An installation platform is fixedly connected to the rear end of the connecting block. A cylinder is installed at the upper end of the installation platform. The output end of the cylinder is connected to the bottom of the limit lifting plate. A dropping slot is provided inside the limit lifting plate.

[0012] Furthermore, the lifting adjustment assembly internally includes a guiding vertical rod installed at the upper end of the protective support plate. A guiding hole matched with the guiding vertical rod is provided inside the limit lifting plate.

[0013] Furthermore, a limit enclosing strip is fixedly connected to the center of the upper end of the limit lifting plate. A hydraulic telescopic rod is installed on one side of the limit enclosing strip. The output end of the hydraulic telescopic rod is connected to one side of the baffle.

[0014] Furthermore, a sliding cavity for enabling the baffle to perform sliding adjustment is formed by enclosing inside the limit enclosing strip. A circular sleeve for stably placing the iron ball is fixedly connected to the upper end of the limit enclosing strip.

[0015] The beneficial effects are as follows: By adjusting the clamping assembly, the present invention can fix the position of the safety shoes. When the iron ball strikes, it can effectively prevent the safety shoes from shifting, making the test experience more accurate and reliable. The lifting and adjusting assembly can quickly and accurately adjust the dropping and striking height of the iron ball according to the experimental needs. Compared with the traditional method of randomly picking up the iron ball by hand to strike, it can more scientifically simulate the striking situations at different heights, so as to more accurately test and experience the anti-striking performance of the safety shoes. By using the free fall of the iron ball to strike the toe of the safety shoes, it can well simulate the situation of foot being struck that may be encountered in actual work, enabling the workers to personally experience the protective effect of wearing safety shoes on the body, thereby enhancing the safety awareness of the workers and making them more deeply realize the importance of wearing safety shoes. The safety shoe striking experience device can realize the clamping and fixing of the safety shoes, as well as the height adjustment and release operation of the iron ball. The operation process is relatively simple, improving the experimental efficiency and experience effect. BRIEF DESCRIPTION OF THE DRAWINGS

Two moving sleeve blocks 304 are threadedly connected to the outer side of the bidirectional lead screw 303.

[0022] A limit moving block 305 is fixedly connected to the upper end of the moving sleeve block 304. An arc-shaped moving plate 306 is fixedly connected to the upper end of the limit moving block 305. A fixed pressing plate 307 is installed inside the arc-shaped moving plate 306.

[0023] A compression-resistant support plate 308 is fixedly connected to the inner side of the fixed pressing plate 307. A clamping side plate 309 is fixedly connected to the inner side of the compression-resistant support plate 308. A buffer soft pad 310 is installed inside the clamping side plate 309.

[0024] Please refer to Figures 5 - 7, in this embodiment, a lifting chute 801 for facilitating the sliding of the inner adjusting steel pipe 701 is provided inside the outer steel pipe 8.

[0025] The lifting adjustment assembly internally includes a guiding vertical rod 901 installed at the upper end of the protective support plate 5. A guiding hole 902 that cooperates with the guiding vertical rod 901 is provided inside the limit lifting plate 702.

[0026] A limit retaining strip 903 is fixedly connected to the center of the upper end of the limit lifting plate 702. A hydraulic telescopic rod 904 is installed on one side of the limit retaining strip 903. The output end of the hydraulic telescopic rod 904 is connected to one side of the baffle 703.

[0027] A sliding cavity 905 for enabling the sliding adjustment of the baffle 703 is formed by enclosing the inner side of the limit retaining strip 903. A circular ring 906 for stably placing the iron ball 704 is fixedly connected to the upper end of the limit retaining strip 903.

[0028] The calculation formula for the free - fall height of an object is: h = gt² / 2 In the case of an initial velocity of zero, h is the falling height, g is the acceleration due to gravity with a general value of 10, and t is the falling time; The velocity calculation formula is: V = gt Where V is the velocity, g is the acceleration due to gravity, and t is the falling time used; mv = mgt = FT Where F is the impact force of the object and m is the mass of the object; The impact force F of the object = mvt; Example: Given that m = 0.5 kg is the mass of the object and the falling time t = 0.39 s, the final velocity v = gt = 3.9 m / s , the impact force F of the object = mvt = 0.5 kg × 3.9 m / s × 0.39 s ≈ 0.76 N; Given that the impact force that the surface of the safety shoe can withstand is 1100 N, it can withstand the gravity impact of the spherical ball.

[0029] When conducting the experience, first place the safety shoe to be tested on the placement platform 403 on the placement tray 4 to ensure that the shoe is placed stably; Start the drive motor 302. The drive motor 302 drives the bidirectional lead screw 303 to rotate. The moving sleeve block 304 outside the bidirectional lead screw 303 moves accordingly, causing the limit movable block 305 to move in a limited manner in the adjustment movable groove 404, and then causing the arc-shaped moving plate 306 to move. Then, the fixed pressing plate 307, the compression support plate 308, and the clamping side plate 309 move towards the safety shoes until the buffer soft pad 310 is in close contact with the safety shoes, firmly fixing the safety shoes. According to the experience needs, start the cylinder 707. The output end of the cylinder 707 pushes the limit lifting plate 702 to move up and down. The limit lifting plate 702 drives the inner adjustment steel pipe 701 to slide in the lifting chute 801 of the outer steel pipe 8. The vertical slide bar 705 ensures the smooth sliding of the inner adjustment steel pipe 701, thereby adjusting the release height of the iron ball 704. The limit lifting plate 702 slides on the guiding vertical rod 901. The guiding hole 902 cooperates with the guiding vertical rod 901 to ensure the stability of the up and down movement of the limit lifting plate 702. Place the iron ball 704 in the circular sleeve 906 inside the limit retaining strip 903. The circular sleeve 906 plays a certain positioning role for the iron ball 704, preventing the iron ball 704 from rolling and falling. Start the hydraulic telescopic rod 904. The output end of the hydraulic telescopic rod 904 pushes the baffle 703 to slide in the sliding cavity 905, causing the iron ball 704 to freely fall from the dropping groove 708 and strike the toe of the safety shoes to simulate the experience of having the foot hit.
