Description

Technical Field

[0001] This invention relates to the field of drop test equipment technology, specifically to an impact table for a high-altitude drop environment test device. Background Technology

[0002] In drop testing, it is necessary to simulate the stress and damage experienced by the test specimen when it is dropped from a great height onto different types of ground surfaces in order to evaluate its adaptability to complex environments. Common simulation scenarios include: the test specimen falling onto a steel plate to simulate a hard ground; falling into a sandpit to simulate a desert or soft ground; and falling into a water tank to simulate the impact of water entry.

[0003] In existing technologies, tests in the aforementioned different scenarios typically need to be conducted separately at independent, fixed test stations or devices. When test tasks require frequent switching between multiple scenarios, this decentralized layout not only occupies a large amount of space, but also the replacement of heavy impact media (such as large steel plates and sandboxes) often relies on manual labor or external hoisting equipment, which is cumbersome, time-consuming, and severely restricts test efficiency. Furthermore, existing devices cannot flexibly and conveniently reproduce more complex composite boundary conditions such as shallow water impacts and sand impacts with varying humidity levels on the same test station. Therefore, there is an urgent need to design an impact test bench that integrates steel plates, sand pits, and water tanks, enabling modular and rapid automatic replacement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an impact test platform for a high-altitude drop environment testing device. The technical problem to be solved is that in existing drop environment tests, impact simulations of various scenarios such as hard ground, desert, and water immersion need to be carried out in separate, dispersed workstations, resulting in a large space occupation. Furthermore, the replacement of heavy impact media (such as steel plates and sandboxes) relies on manual labor or external hoisting equipment, which has the drawbacks of cumbersome operation and low switching efficiency. This invention provides an impact test platform that integrates steel plates, sand pits, and water pools, enabling modular and rapid automatic replacement.

The sandbox can be moved into the water tank and placed on the stepped support platform. It is filled with sand to create a simulated desert impact scene. Multiple sieves are evenly distributed on its lower wall. The sieves are breathable and water-permeable while preventing sand particles from passing through. When the sandbox is in the water tank, the water level of the tank is raised to submerge the sand, creating a simulated shallow beach impact scene. Multiple reinforcing ribs are arranged on the outer side of the lower wall of the sandbox. A pair of movable frames are slidably set in the troughs located on both sides of the water tank. The movable frames are equipped with liftable support rods, which drive the frame or sandbox to move upward and into or out of the water tank. The frame and sandbox can be transported by moving the two movable frames synchronously.

[0006] Preferably, a frame storage slot is provided on one side of the water tank on the platform, and a scissor lift is provided at the bottom of the frame storage slot. After the scissor lift is raised, it can push the steel plate out of the frame. Multiple first conveying rollers are provided on the upper surface of the telescopic end of the scissor lift, and multiple second conveying rollers are provided on one side of the frame storage slot on the platform. A stop block is fixedly provided on the top of the side wall away from the second conveying rollers above the frame.

[0007] Preferably, it also includes a grating plate, which can be placed on the eaves. The steel plate is placed on the grating plate, and the scissor lift can push the steel plate and the grating plate out of the frame at the same time after the scissor lift is raised.

[0008] Preferably, a sandbox storage tank is provided on the other side of the water tank on the platform. The bottom of the sandbox storage tank is connected to a drain pipe with a valve, and an air supply pipe is also connected to the drain pipe.

[0009] Preferably, an L-shaped pipe is fixedly installed on one side of the sand box storage tank on the platform. Multiple rows of branch pipes are evenly distributed on both sides of the horizontal bar of the L-shaped pipe. Each branch pipe is connected to a spray head, and a water inlet is provided at the vertical pipe of the L-shaped pipe.

[0010] Preferably, the platform is provided with two slide rails between the water tank and the slide chute, the mobile frame is provided with multiple load-bearing wheels that roll on the slide rails, and the bottom of the mobile frame is provided with multiple pairs of limiting wheels that abut against the inner walls on both sides of the slide chute.

[0011] Preferably, it also includes two chains and a device slot. The device slot is located in a platform near one end of a pair of slides. A rope hole is provided between the device slot and the slides. A pair of rotating shafts are rotatably installed in the device slot. Two pairs of sprockets are fixedly installed on the pair of rotating shafts corresponding to the pair of slides. Two pairs of sprockets are rotatably installed in the end of the pair of slides away from the device slot. The two chains pass through the rope hole and are wound around the two pairs of sprockets and the two pairs of sprockets respectively. The two chains correspond one-to-one with a pair of movable frames. The two ends of each chain are fixedly connected to the two sides of the corresponding movable frame respectively.

[0015] This invention provides an impact platform for a high-altitude drop environment testing device, which has the following beneficial effects: The impact test platform modularly combines a water tank, a frame (with steel plates) that can sit inside the water tank, and a sandbox, enabling it to perform water impact, hard ground impact, and desert impact scenarios. With a pair of movable frames that can move synchronously within the chute and liftable support rods, it can automatically transport and replace the frame or sandbox between the storage tank and the water tank without the need for external hoisting equipment, significantly improving the switching efficiency and automation level of multi-scenario testing. A water tank is located in the center of the platform, and the frame and sandbox can be moved into the water tank and placed on the stepped support platform inside. This structure allows water impact scenarios and hard ground / desert impact scenarios to share the same water tank foundation without the need for separate water pools and impact pits, making the overall structure much more compact and saving test space. The sandbox is equipped with a breathable and water-permeable sieve plate at the bottom. When the sandbox is placed in a water tank and water is poured into the tank to cover the sand surface, it can simulate shallow sand impact. When dry air is injected into the sandbox storage tank, the gas passes through the sieve plate and the gaps between the sand grains to remove moisture and reduce sand humidity. Water can also be sprayed into the sandbox through L-shaped pipes and spray heads to increase sand humidity. This scheme can flexibly simulate various sandy conditions, from dry deserts to saturated shallow sands, expanding the simulation range of the experiment. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Please see Figures 1-10 The present invention provides a technical solution: an impact platform for a high-altitude drop environment testing device, comprising: Platform 1 has a base 2 fixed at its four corners to support the lifting device. A water tank 3 is provided in the middle. The test specimen that is removed from the lifting device can fall into the water tank 3. The bottom of the water tank 3 is connected to the inlet and outlet water pipes 4 with valves. By injecting water into the water tank 3, a water impact simulation scene can be formed. A stepped support platform 5 is also provided inside the water tank 3. The frame 6 can be moved into the water tank 3 and sit on the stepped support platform 5. It has a detachable steel plate 7 inside to form a simulated hard ground impact scene. The inner surface of the frame 6 is provided with a protruding eave 14 to support the steel plate 7, so that the steel plate 7 can be supported at the four edges. Even if the steel plate 7 is deformed due to impact, it will not damage the frame 6. Multiple reinforcing ribs 15 are fixedly provided at the bottom of the protruding eave 14 to improve the support strength of the protruding eave 14. The sandbox 8 can be moved into the water tank 3 and placed on the stepped support platform 5. It is filled with sand to form a simulated desert impact scene. Multiple sieve plates 9 are evenly distributed on its lower wall. The sieve plates 9 are breathable and water-permeable and prevent sand particles from passing through. When the sandbox 8 is in the water tank 3, the water level of the water tank 3 is raised to submerge the upper surface of the sand to form a simulated shallow beach impact scene. Multiple reinforcing ribs 10 are arranged on the outer side of the lower wall of the sandbox 8 to increase the deformation resistance of the bottom of the sandbox 8. A pair of movable frames 11 are slidably set in the troughs 12 located on both sides of the water tank 3. The movable frames 11 are equipped with liftable support rods 13. The support rods 13 drive the frame 6 or sandbox 8 to move upward and into or out of the water tank 3. The frame 6 and sandbox 8 are transported by moving the pair of movable frames 11 synchronously.

[0020] Furthermore, a frame storage slot 16 is provided on one side of the water tank 3 on the platform 1. A scissor lift platform 17 is provided at the bottom of the frame storage slot 16. After the scissor lift platform 17 is raised, it can push the steel plate 7 out of the frame 6, which is convenient for replacing the steel plate 7 in the frame 6. Multiple first conveying rollers 18 are provided on the upper surface of the telescopic end of the scissor lift platform 17. Multiple second conveying rollers 19 are provided on one side of the frame storage slot 16 on the platform 1. After the steel plate 7 is pushed out, it can be moved easily by the first conveying rollers 18 and the second conveying rollers 19. A stop block 20 is fixedly provided on the top of the side wall away from the second conveying rollers 19 on the upper part of the frame 6. The movement of the steel plate 7 can be limited by the stop block 20, which is convenient for aligning the steel plate 7 with the frame 6.

[0021] As an embodiment of the present invention, it also includes a grating plate 44, which can be placed on the eaves 14. The steel plate 7 is placed on the grating plate 44. The grating plate 44 can provide planar support for the bottom of the steel plate 7. The deformation resistance of the grating plate 44 is better than that of the steel plate 7 of the same weight, which improves the overall rigidity of the contact surface when simulating the impact scenario of hard ground. After the scissor lift platform 17 is raised, it can push the steel plate 7 and the grating plate 44 out of the frame 6 at the same time, which facilitates the replacement of the grating plate 44 and the steel plate 7.

[0022] As an embodiment of the present invention, a sand box storage tank 21 is provided on the platform 1 on the other side of the water tank 3. The bottom of the sand box storage tank 21 is connected to a drain pipe 22 with a valve. Water flowing out of the sieve plate 9 at the bottom of the sand box 8 is discharged through the drain pipe 22. An air supply pipe 23 is also connected to the drain pipe 22. Dry air can be injected into the sand box storage tank 21 through the air supply pipe 23. The dry air enters the sand box 8 through the sieve plate 9 to dry the sand and reduce the humidity in the sand. The dry air can be prevented from being discharged through the drain pipe 22 by closing the valve on the drain pipe 22.

[0023] Furthermore, an L-shaped pipe 24 is fixedly installed on one side of the sand storage tank 21 on platform 1. Multiple rows of branch pipes 25 are evenly distributed on both sides of the horizontal bar of the L-shaped pipe 24. Each branch pipe 25 is connected to a spray head 26. A water inlet 27 is provided at the vertical pipe of the L-shaped pipe 24. After the water inlet 27 is connected to an external water source, water can be sprayed into the sand box 8 through the spray head 26 to increase the humidity in the sand.

[0024] As an embodiment of the present invention, two slide rails 28 are provided on the platform 1 between the water tank 3 and the slide 12. Multiple load-bearing wheels 29 are provided on the movable frame 11, which can move along the length direction of the slide 12. Multiple pairs of limiting wheels 30 are rotatably provided at the bottom of the movable frame 11, which abut against the inner walls on both sides of the slide 12, to ensure that the movable frame 11 can be in a vertical position in the slide 12. The load-bearing wheels 29 have an H-shaped cross-section, which can prevent axial movement on the slide rails 28.

[0025] Furthermore, it also includes two chains 31 and an equipment groove 32. The equipment groove 32 is set in the platform 1 near one end of a pair of slides 12. A rope hole 33 is provided between the equipment groove 32 and the slides 12. A pair of rotating shafts 34 are rotatably arranged in the equipment groove 32. Two pairs of sprockets 35 are fixedly arranged on the pair of rotating shafts 34 corresponding to the pair of slides 12. Two pairs of sprockets 36 are rotatably arranged in the end of the pair of slides 12 away from the equipment groove 32. The two chains 31 pass through the rope hole 33 and are wound around the two pairs of sprockets 35 and the two pairs of sprockets 36 respectively. The two chains 31 correspond one-to-one with a pair of moving frames 11. The two ends of each chain 31 are fixedly connected to the two sides of the corresponding moving frame 11. The rotation of the rotating shaft 34 can drive the two chains 31 to rotate simultaneously, thereby driving the pair of moving frames 11 to move synchronously. The movement direction of the pair of moving frames 11 can be changed by controlling the rotation direction of the rotating shaft 34.

[0026] Furthermore, a reducer 37 is fixedly installed inside the equipment slot 32. The power input end of the reducer 37 is connected to a motor 38, and the power output end of the reducer 37 is connected to one of a pair of rotating shafts 34. The power output by the motor 38 is reduced by the reducer 37 and then drives the rotating shaft 34 to rotate, thus providing power to the rotating shaft 34.

[0027] As an embodiment of the present invention, a pair of guide cylinders 39 are fixedly installed on the movable frame 11, and a guide rod 40 is slidably installed inside the pair of guide cylinders 39. The support rod 13 is fixedly installed on the top of the guide rod 40. The cooperation between the guide cylinders 39 and the guide rod 40 ensures that the support rod 13 moves linearly in the vertical direction. A power telescopic rod 41 is fixedly installed inside the movable frame 11. The telescopic end of the power telescopic rod 41 is connected to the support rod 13. The power telescopic rod 41 provides power for the lifting and lowering of the support rod 13. The power telescopic rod 41 is either an electric telescopic rod or a hydraulic telescopic rod.

[0028] Furthermore, both sides of the frame 6 and the sandbox 8 are provided with multiple extension lugs 42 that cooperate with the support rod 13. The upper surface of the support rod 13 is provided with positioning grooves 43 corresponding to the multiple extension lugs 42 to ensure the relative position between the extension lugs 42 and the support rod 13 and to prevent slippage.

[0029] Working principle and usage process of this invention: When in use, first connect the inlet and outlet water pipes 4 and the water inlet 27 to the external water source, and connect the air supply pipe 23 to the external high-pressure air pump.

[0030] Water impact scenario: After water is injected into the water tank 3, the valves on the inlet and outlet water pipes 4 (not shown in the figure) are closed to form a simulated scenario with controllable water depth. The water depth is controlled by controlling the amount of water injected. The test specimen is lifted to the set height by the lifting device and then placed into the water tank 3 to realize the drop test of the test specimen into the water.

[0031] Impact scenario on hard ground: To prevent the water in the water tank 3 from soaking the frame 6, the valves on the inlet and outlet water pipes 4 should be opened to drain the water from the water tank 3, or the water level should be lower than the stepped support platform 5. Starting the motor 38 will cause the rotating shaft 34 to rotate. The rotation of the rotating shaft 34 will control the synchronous movement of a pair of movable frames 11. When the support rod 13 is at its lowest point, the movement of the movable frames 11 will move the support rod 13 under the extension lug 42. After the two are vertically aligned, the support rod 13 will be driven to rise by the power telescopic rod 41, thus lifting the frame. The test specimen is lifted out of the storage slot 16 and then moved to a position directly above the water tank 3 by a pair of movable frames 11. The frame 6 is then placed onto the stepped support platform 5 inside the water tank 3 by retracting the power telescopic rod 41. The stepped support platform 5 supports the frame 6. The test specimen is then lifted to a set height by a lifting device and dropped into the frame 6 to contact the steel plate 7, thus performing a drop test on a hard surface. After the test, the frame 6 can be moved back into the storage slot 16 by the movable frame 11 and the support rod 13. When the steel plate 7 needs to be replaced, the scissor lift platform 17 is activated to push the steel plate 7 upwards from the frame 6. The process stops when the steel plate 7 is higher than the side wall of the frame 6. At this point, the first conveying roller 18 and the second conveying roller 19 are at the same horizontal level, making it easy to remove the steel plate 7.

[0032] As an implementation scheme for a hard ground impact scenario, a grating plate 44 is first placed on the eaves 14, and the steel plate 7 is placed on top of the grating plate 44, so that the steel plate 7 is supported by the grating plate 44, thereby improving the overall stiffness of the contact surface when simulating a hard ground impact scenario.

[0033] Desert drop test scenario: The sand box 8 is lifted from the sand box storage tank 21 and moved directly above the water tank 3 using a pair of movable frames 11 and support rods 13. The sand box 8 is then placed onto the stepped support platform 5 inside the water tank 3 by retracting the power telescopic rod 41. The stepped support platform 5 supports the sand box 8. The specimen is then lifted to a set height using a lifting device and dropped into the sand box 8 to contact the sand, thus completing the desert drop test. After the test, the sand box 8 can be moved back into the sand box storage tank 21 using the movable frames 11 and support rods 13. When it is necessary to increase the sand humidity, external water flows into each branch pipe 25 through the L-shaped pipe 24. The water is then sprayed into the sand through the spray nozzles 26 on each branch pipe 25 to increase the sand humidity. When it is necessary to reduce the moisture of the sand, close the valve on the drain end of the drain pipe 22, and pump the dry gas into the sand box storage tank 21 through an external high-pressure air pump. At this time, most of the gas can enter the sand box 8 through the bottom sieve plate 9. The gas flows through the gaps between the sand grains to carry out the moisture in the sand, thereby reducing the moisture of the sand.

[0034] By controlling the water level in the water tank 3 to be lower than the upper port of the water tank 3, controlling the upper surface of the sand to be lower than the upper port of the sandbox 8, and controlling the upper surface of the steel plate 7 to be lower than the upper port of the frame 6, a pit-like test scenario can be achieved, which avoids the fragments from the test specimen being impacted and broken and splashing in all directions, thus protecting the personal safety of nearby personnel.

[0035] Shallow beach simulation scenario: When the sandbox 8 is in the water tank 3, water is filled into the water tank 3 so that the water covers the upper surface of the sand. The distance between the water surface and the upper surface of the sand can be controlled by controlling the water level.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
