[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] As Figure 1 shown, a high-drop experience device includes a frame 1, a lifting platform 4, and a safety belt 3. The lifting platform 4 is provided with a cavity, the safety belt 3 is connected to the top of the cavity, and the lifting platform 4 is arranged at the bottom of the cavity.

[0031] Its working principle is as follows: The frame 1 provides a supporting force for the safety belt 3, the lifting platform 4 lifts the human body to the area of the safety belt 3, the safety belt 3 is tied to the human body, and the lifting platform 4 quickly descends, enabling the human body to experience the feeling of weightlessness, which is used for weightlessness training of personnel while ensuring safety, deepening the safety risk awareness of personnel, or replacing the human body with a test article such as a dummy for fatigue testing of the safety belt 3 to detect its quality.

[0032] According to the above working principle, the following embodiments or implementation manners can be provided:

[0033] In some embodiments, the lifting platform 4 includes a support platform 41, a first support arm 42, a second support arm 43, and a telescopic cylinder 44. The bottom of the support platform 41 is connected with the first support arm 42 and the second support arm 43. The middle parts of the first support arm 42 and the second support arm 43 are rotatably connected. One end of the first support arm 42 is slidably connected to the bottom of the support platform 41, the other end of the first support arm 42 is fixed to the bottom of the frame 1, one end of the second support arm 43 is located on one side of the other end of the first support arm 42 and is fixedly connected to the bottom of the support platform 41, the other end of the second support arm 43 is arranged on one side of the other end of the first support arm 42 and is slidably connected to the frame 1. The telescopic cylinder 44 is connected between the other ends of the first support arm 42 and the second support arm 43. The telescopic cylinder 44 can be a pneumatic cylinder or a hydraulic cylinder. The support platform 41 is used to support the human body or goods. Under the action of the telescopic cylinder 44, the first support arm 42 and the second support arm 43 make the other end far from the support platform 41 move relatively, so that the end close to the support platform 41 also generates relative movement, and both ends slide relatively along the bottom of the support platform 41 and the bottom of the cavity respectively, and produce a lifting effect on the support platform, thereby driving the human body or dummy to lift and lower.

[0034] In some embodiments, the lifting platform 4 includes a scissor lift. The scissor lift has a simple structure and is easy to arrange in the cavity. It is conceivable that some other lifting platforms 4 or devices can also be used as long as they meet the requirements of the above working principle.

[0035] In some embodiments, a cushion is provided on the top of the lifting platform 4; cushions are provided on both sides of the cavity. The cushions can improve the safety during the human experience process or prevent the loss of items or the device during the test process.

[0036] In some embodiments, the lifting height of the lifting platform 4 is greater than the falling height of the test article. This can ensure that after the human body or the test object rises to an appropriate height, it can be tied by the safety belt 3, and when the lifting platform 4 descends, it will not touch the lifting platform 4. However, the safety height of the safety belt 3 should also be considered to prevent the danger of too high a fall.

[0037] In some embodiments, a lifting ring 2 is provided at the top of the cavity, and the safety belt 3 is connected to the frame 1 through the lifting ring 2.

[0038] In some embodiments, the safety belt 3 is a double-hook safety belt 3. The double-hook safety belt 3 is a commonly used safety belt 3, with high safety and a simple structure, which can further streamline the structure of the high-drop experience device.

[0039] According to the above, the present invention also provides a high-drop experience method, which is characterized by including:

[0040] S1. Set any of the above high-drop experience devices;

[0041] S2. Lift the test article to a preset height through the lifting platform 4;

[0042] S3. Securely fasten with the safety belt 3;

[0043] S4. Lower the test article to free fall through the lifting platform 4;

[0044] S5. Prevent the test article from colliding with the lifting platform 4 after free fall through the safety belt 3.

[0045] The method further includes: S6. Prevent the test article from directly contacting the side of the cavity or the lifting platform 4 through the cushion.

[0046] The method further includes: S7. Verify the quality of the safety belt 3 by conducting a fatigue test on the safety belt 3.

[0047] In a specific embodiment, this device is processed from ordinary structural steel. The frame 1 is welded from channel steel to form an integral device with a height of 3.5 meters. The lower lifting platform 4 is welded from angle iron. One end of the first arm 42 and the second arm 43 of the lifting platform 4 is fixed, and the other end is equipped with rollers 5, which can realize the rolling of the rollers 5 around the arm rotating shaft, change the angles of the two arms, and cylinders are installed on the two arms and connected at both ends with supports, pins and spherical plain bearings. When the cylinders extend or retract, the lifting platform 4 below the safety belt 3 can be lowered and raised. A total of three sets of lifting platforms 4 are installed on the device, with three workstations, enabling three people to experience high falls simultaneously. The frame 1 serves to fix the hanging ring 2; the hanging ring 2 serves to hang the double-hook safety belt 3; the double-hook safety belt 3 realizes the function of tying a person to the hanging ring 2 and ensures the safety of the person when the lifting platform 4 descends; the lifting platform 4 functions to rise and fall. When rising, it lifts the person, and when descending, the piston rod of the cylinder suddenly extends. When the person falls, the double-hook safety belt 3 lifts the person to achieve the experience of a high fall; after the cylinder is ventilated, the piston rod of the cylinder extends and retracts, serving to lower and lift the lifting platform 4; the solenoid valve serves to control the ventilation of the inlet and outlet of the cylinder; the air compressor is used to supply air to the cylinder to achieve the purpose of inlet and outlet ventilation; the air pipe serves to connect the air compressor, the solenoid valve and the cylinder; the remote control serves to achieve the purpose of electrical control; the present invention designs a set of high-fall experience device system, and the platform occupies about 3m 2 , with a length of 3m and a width of 1 meter, and three experience workstations are set up, allowing three people to experience simultaneously. The experience device system is designed to be movable and can be installed at a designated location as needed. The arms for high-fall experience play a supporting role and are load-bearing support structures; the suspension system consists of the hanging ring 2 and the five-point safety belt 3. The hanging ring 2 is designed to withstand an impact load of 3 tons according to national standards, and the five-point safety belt 3 is configured according to national standards. For the lifting platform 4 of the high-fall experience device, the support platform 41 is welded from checkered steel plates with a thickness of 5mm. After the support platform 41 descends, the total height is 0.34m, and after rising, the total height is 0.77m. The actuator is supplied with air by an air compressor, with a supply pressure of 0.8 MPa, a cylinder bore of 100mm, and a stroke of 150mm, which is used to realize the functions of rising and falling of the lifting platform 4 and the effect of experiencing instantaneous weightlessness.

[0048] During the experience, a person stands on the high-fall experience device. Refer to Figure 2 as shown. At this time, the lifting platform 4 is in the rising position. Fasten the five-point safety belt 3 and adjust the safety belt 3 to a taut state. After standing firmly, refer to Figure 1 as shown. Start the air compressor and the remote control. The cylinder retracts, and the lifting platform 4 quickly descends to experience instantaneous weightlessness. After the person stabilizes, the lifting platform 4 slowly rises. The person stands on the fixed part of the platform, unfastens the safety belt 3 and gets off the platform.

[0049] In order to experience the momentary sense of weightlessness during a high fall, this embodiment provides a high fall experience device with a lifting platform 4 equipped with a cylinder as the actuator, ensuring the safety and practicality of the experience while experiencing it.
