[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 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 shall fall within the protection scope of the present invention. The embodiments of the present invention will be described below according to its overall structure.

[0030] The detailed implementation manner of the present invention is as follows:

[0031] Embodiment 1:

[0032] As shown in the attached Figures 1 - 4As shown in the figure, a safety helmet impact experience device with an automatic demonstration function includes an experience cabin 1 and a controller. A lifting platform 2 is provided inside the experience cabin 1. A vertically arranged guide cylinder 3 is provided at the top of the experience cabin 1. A suspension rope 4 and a suspension ball 31 provided at the bottom of the suspension rope 4 pass through the guide cylinder 3. A vertical guide rail 5 is provided at the top end of the outer wall of the experience cabin 1. A lifting seat 6 is slidably provided on the vertical guide rail 5, and a lead screw elevator 7 for driving the lifting seat 6 is provided on the vertical guide rail 5. A wire winding and unwinding mechanism capable of pulling the suspension rope 4 upward is provided on the lifting seat 6. Two demonstration platforms 8 are slidably provided on both sides of the lifting platform 2. A standing slot 55 is provided in the middle of the lifting platform 2. A transposition mechanism 9 for transporting the demonstration platforms 8 to the middle of the lifting platform 2 is provided on the lifting platform 2. Dummies 10 are placed on the two demonstration platforms 8. The first motor, the second motor, the third motor, and the electric push rod are electrically connected to the controller.

[0033] In this safety helmet impact experience device with an automatic demonstration function, the lead screw elevator 7 provided on the vertical guide rail 5 can drive the lifting seat 6 to rise or fall, adjusting the height of the lifting seat 6. The wire winding and unwinding mechanism on the lifting seat 6 can pull the suspension rope 4. After the suspension ball 31 at the bottom of the suspension rope 4 rises to a certain height, the wire winding and unwinding mechanism releases the suspension rope 4, causing the suspension ball 31 of the suspension rope 4 to fall freely, and then it can hit the dummy 10 on the lower lifting platform 2 or hit the safety helmet on the head of the experience personnel standing at the standing slot 55 in the middle of the lifting platform 2. Among them, during the descent of the suspension rope 4, the guide cylinder 3 guides the suspension ball 31, and the suspension rope 4 and the suspension ball 31 are not prone to shaking, ensuring that it can accurately hit the head of the dummy 10 below or hit the safety helmet on the head of the experience personnel standing on the lifting platform 2.

[0034] In this safety helmet impact experience device with an automatic demonstration function, the lifting platform 2 can be lifted, adjusting the height of the demonstration platforms 8 and the height of the experience personnel standing on the platform surface of the lifting platform 2, simulating the scenario of being hit by the suspension ball 31 at different heights, and increasing the awareness of the importance of wearing a safety helmet among the trainees.

[0035] In this safety helmet impact experience device with an automatic demonstration function, the head of the dummy 10 is a plaster head model that is detachably sleeved on the neck of the dummy 10. One of the dummies 10 on the two demonstration platforms 8 does not wear a safety helmet, and the head of the other dummy 10 wears a safety helmet. The two demonstration platforms 8 can be respectively transported to the central position of the lifting platform 2 through the transposition mechanism 9, so that the dummy 10 is directly below the hanging ball 31, thereby simulating the damage degree caused by a high-altitude object hitting the plaster head model of the dummy 10 without wearing a safety helmet, and simulating the damage degree caused by a high-altitude object hitting the plaster head model of the dummy 10 wearing a safety helmet. By comparing the two simulation demonstrations, the necessity of wearing a safety helmet can be obtained, so that the trainees can correctly recognize the importance of wearing a safety helmet in the factory.

[0036] A preferred implementation manner of this embodiment is that the transposition mechanism 9 includes a rotating shaft 11 rotatably provided on both sides of the lifting platform 2 through bearings and a third motor 12 for driving the rotating shaft 11 to rotate. A bevel gear transmission assembly is provided between the bottom of the rotating shaft 11 and the output end of the third motor 12. The top of the rotating shaft 11 is provided with a swing arm 13 connected to the demonstration platform 8. Two arc-shaped slide rails 14 extending to the center are provided on both sides of the top surface of the lifting platform 2. A pulley assembly 15 adapted to the arc-shaped slide rails 14 is provided at the bottom of the demonstration platform 8.

[0037] In this embodiment, the pulley assembly 15 is provided at the bottom of the demonstration platform 8. The pulley assembly 15 can slide under the guidance of the arc-shaped slide rails 14 of the lifting platform 2. The rotating shaft 11 is driven to rotate a certain angle by the third motor 12 and the bevel gear transmission assembly, so that the swing arm 13 and the demonstration platform 8 make a circular motion, and the demonstration platform 8 is moved from one side to the center of the lifting platform 2.

[0038] A preferred implementation manner of this embodiment is that a lifting column 16 is provided at the bottom of the lifting platform 2, a base 17 is provided below the lifting column 16, and a screw jack two 18 is provided between the base 17 and the lifting column 16. In this embodiment, the screw jack two 18 can drive the lifting column 16 to lift, so as to drive the lifting platform 2 to lift.

[0039] A preferred implementation manner of this embodiment is that an installation groove 19 is hollowed out in the lifting column 16, a guiding groove 20 adapted to the outer wall of the lifting column 16 is formed in the base 17, the screw jack two 18 includes two guiding rods 21 vertically arranged in the guiding groove 20 and a second screw rod 22 arranged between the two guiding rods 21. The bottom of the second screw rod 22 is rotatably connected to the bottom of the guiding groove 20 through a bearing. A guiding seat 23 slidably connected to the guiding rod 21 is fixedly arranged in the installation groove 19. The guiding seat 23 is provided with a guiding hole adapted to the guiding rod 21 and a second screw nut 24 adapted to the second screw rod 22. A second motor 25 drivingly connected to the second screw rod 22 is arranged in the guiding groove 20. A bevel gear transmission assembly is arranged between the output end of the second motor 25 and the second screw rod 22.

[0040] In this embodiment, the guiding seat 23 can linearly slide up and down under the guidance of the two guiding rods 21. After the second motor 25 is started, it drives the second screw rod 22 to rotate through the bevel gear transmission assembly, drives the second screw nut 24 and the guiding seat 23 to rise and fall, thereby driving the lifting column 16 and the lifting platform 2 to rise and fall, so as to realize adjusting the height of the tabletop of the lifting platform 2 from the ground.

[0041] A preferred implementation manner of this embodiment is that a hinge seat 26 is arranged on the side wall of the experience cabin 1. A height limiting ruler 53 capable of horizontally rotating is hinged on the hinge seat 26. One end of the height limiting ruler 53 is fixedly provided with a hinge shaft 27 rotatably connected to the hinge seat 26. A first gear 28 is arranged on the hinge shaft 27. A rack 29 meshing with the first gear 28 is horizontally slidably arranged on the side wall of the experience cabin 1. An electric telescopic rod 30 connected to the rack 29 is arranged on the side wall of the experience cabin 1. A position sensor 54 electrically connected to the controller is arranged on the bottom surface of the end of the height limiting ruler 53.

[0042] In this embodiment, a height limit ruler 53 that can swing is arranged above the lifting platform 2. During the simulation experience, after wearing a safety helmet, the trainee stands on the two footprints in the middle of the lifting platform 2 and presses the lifting switch on the cabin wall of the experience cabin 1. After the second motor 25 is started, it drives the second lead screw 22 to rotate through the bevel gear transmission assembly, driving the second lead screw nut 24 and the guide seat 23 to rise, thereby driving the lifting column 16 and the lifting platform 2 to rise, so as to adjust the height of the safety helmet worn by the trainee from the ground. During the height adjustment process, when the position sensor 54 of the height limit ruler 53 senses the safety helmet worn by the trainee, it proves that the trainee has reached the set experience height. The position sensor 54 sends a signal to the controller, and the controller automatically controls the second motor 25 to stop, and then automatically controls the wire winding and unwinding mechanism to release the suspension rope 4, so that the hanging ball 31 falls freely, simulating the feeling of being hit by an object from a height on the safety helmet. By adjusting the sensing distance of the position sensor 54 on the control panel of the controller to different values, the feeling of being hit by an object from different heights on the safety helmet can be simulated.

[0043] In this embodiment, the hanging ball 31 has a hollow ball structure, and a window for placing counterweight weights is provided on the shell of the hollow ball structure. A window that can be opened and closed is arranged on the window, and different weights of counterweight weights can be placed in the hanging ball 31 to simulate the feeling of being hit by an object from a height with different weights.

[0044] A preferred implementation manner of this embodiment is that the vertical guide rail 5 includes a gantry 36 and two guide columns 37 arranged on both sides of the gantry 36. The screw jack 7 includes a first lead screw 38 rotatably arranged between the two guide columns 37 and a first lead screw nut 39 arranged on the lifting seat 6 and adapted to the first lead screw 38. A first motor 40 for driving the first lead screw 38 to rotate is arranged at the bottom of the gantry 36. In this embodiment, the screw jack 7 can drive the lifting seat 6 to move up and down to adjust the height of the wire winding and unwinding mechanism on the lifting seat 6.

[0045] A preferred implementation manner of this embodiment is that the wire winding and unwinding mechanism includes an electromagnetic lock 32 arranged on the lifting seat 6 and disposed directly above the suspension rope 4. The top end of the suspension rope 4 is provided with a lock head 34 that can be attracted by the magnetic attraction structure 33 of the electromagnetic lock 32. The electromagnetic lock 32 is a conventional electromagnet structure, which utilizes the principle of electricity generating magnetism. When current passes through the silicon steel sheet, the magnetic attraction structure 33 of the electromagnetic lock 32 will generate a strong suction force to attract and hold the adsorption lock head 34 to fix the lock head 34 and the magnetic attraction structure 33. A limiting flange 35 adapted to the top surface of the guide cylinder 3 is arranged at the bottom of the lock head 34. An insertion rod 55 that can be inserted into the guide cylinder 3 is arranged at the bottom of the limiting flange 35, and a buffer spring is fixedly arranged on the bottom surface of the limiting flange 35.

[0046] In this embodiment, the lead screw lift 7 can drive the lifting seat 6 to move up and down to adjust the height of the wire winding and unwinding mechanism. When the wire winding and unwinding mechanism descends to the lowest point, the controller controls the magnetic structure 33 of the electromagnetic lock 32 to be energized, and the magnetic structure 33 of the electromagnetic lock 32 can attract the lock head 34 at the top of the suspension rope 4. Then, the lead screw lift 7 drives the wire winding and unwinding mechanism to rise. After the lock head 34, the suspension rope 4, and the hanging ball 31 rise to a certain height, the controller controls the magnetic structure 33 of the electromagnetic lock 32 to be de-energized, and the lock head 34, the suspension rope 4, and the hanging ball 31 can be released to perform free fall motion, and the hanging ball 31 hits the hard hat on the head of the dummy 10 or the training participants below.

[0047] The limiting convex edge 35 has a limiting effect to prevent the suspension rope 4 and the hanging ball 31 from falling completely. When the lock head 34 falls, it contacts the top surface of the guide cylinder 3 through the buffer spring, playing a buffering role to avoid violent collision between the lock head 34 and the guide cylinder 3.

[0048] Embodiment 2:

[0049] The technical solution of this embodiment is roughly the same as that of Embodiment 1. The difference lies in the structural design of the wire winding and unwinding mechanism.

A winding and unwinding drum 42 is rotatably provided on the support 41. A winding and unwinding rope 43 connected to the suspension rope 4 is provided on the winding and unwinding drum 42. A fourth motor 44 for driving the winding and unwinding drum 42 to rotate forward and backward is provided on the support 41. A wire aligner 45 for driving the winding and unwinding rope 43 to move left and right is provided on the front side of the winding and unwinding drum 42 on the support 41. The second motor, the third motor, the fourth motor, the electric push rod, the pressure sensor are electrically connected to the controller.

[0050] In the safety helmet impact experience device with an automatic demonstration function of this embodiment, when the fourth motor 44 drives the winding and unwinding drum 42 to rotate forward, the winding and unwinding rope 43 can be wound onto the winding and unwinding drum 42, so that the hanging ball 31 at the bottom of the suspension rope 4 rises into the guide cylinder 3. Then, the controller controls the fourth motor 44 to rotate backward, driving the winding and unwinding drum 42 to rotate backward quickly, so that the hanging ball 31 can perform free fall. The hanging ball 31 is guided by the guide cylinder 3 and is not prone to position deviation during the descent process, and can accurately hit the hard hat of the dummy 10 or the training participants below.

[0051] In the safety helmet impact experience device with an automatic demonstration function of this embodiment, the lifting seat 6 can move up and down, which can further increase the height position of the wire winding and unwinding mechanism and further increase the maximum distance of the hanging ball 31 from the ground.

[0052] A preferred implementation manner of this embodiment is that the wire aligner 45 includes a cross bar 46 provided on the front side of the support 41 and a reciprocating lead screw 47 arranged in parallel with the cross bar 46. The reciprocating lead screw 47 is rotatably connected to the support 41 through a bearing. A synchronous gear assembly 48 is provided between one end of the reciprocating lead screw 47 and one end of the winding and unwinding reel 42. A slide block 49 slidably connected to the cross bar 46 is connected to the reciprocating lead screw 47 through a ball nut. A wire aligning loop 50 for the winding and unwinding rope 43 to pass through is provided on the slide block 49.

[0053] In this embodiment, the fourth motor 44 drives the winding and unwinding reel 42 to rotate, and can drive the reciprocating lead screw 47 to rotate synchronously through the synchronous gear assembly 48, so as to drive the slide block 49 to reciprocate left and right along the cross bar 46, and make the wire aligning loop 50 push the winding and unwinding rope 43 to move left and right, so that the winding and unwinding rope 43 can be neatly wound onto the winding and unwinding reel 42.

[0054] In this embodiment, a limiting ball 51 is provided between the winding and unwinding rope 43 and the lifting rope 4. The hanging ball 31 can slide into the guiding cylinder 3. A limiting ring 52 for blocking the upward movement of the hanging ball 31 is provided at the top end of the inner wall of the guiding cylinder 3. The limiting ball 51 can pass through the limiting ring 52. Pressure sensors are provided on the bottom surface of the limiting ring 52. When the pressure sensors sense pressure, they can send sensing signals to the controller, and the controller controls the fourth motor 44 to stop.
