DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, an embodiment of the present invention provides an elevator safety experience training device, including an elevator shaft 1, first lifting components 2 are fixedly installed on the left and right sides of the inner bottom of the elevator shaft 1, an L-shaped fixed connecting plate 4 is fixedly sleeved on the middle part of the outer surface of the first lifting component 2, a car box 5 is fixedly installed between the two L-shaped fixed connecting plates 4, the other end of the first lifting component 2 is fixedly connected to the second lifting component 3, a first fixed plate 6 is fixedly installed below the L-shaped fixed connecting plate 4 on the inner wall of the left and right sides of the elevator shaft 1, and two sets of second fixed plates 6 are fixedly installed on the outer surfaces of the front and rear sides of the first fixed plate 6. There are two fixed plates 7 and each group of second fixed plates 7 has two, a fixed rod 8 is fixedly installed between the second fixed plates 7, the outer surface of the fixed rod 8 is movably sleeved with a first spring 9, the outer surface of the fixed rod 8 is movably sleeved with a sliding plate 10 and one end of the first spring 9 is fixedly connected thereto, a roller 11 is rotatably installed on the inner side of the sliding plate 10, a push plate 12 is fixedly sleeved on the outer surface of the roller 11, a push plate 12 is fixedly installed on the outer surface of the push plate 12, a first buffer spring 14 is fixedly installed on the top of the push plate 12, and the first buffer spring 14 is fixedly connected to the first buffer plate 15.

[0027] When safety experience training is required, the first lifting component 2 is started. At this time, the first lifting component 2 simulates the falling safety experience according to the setting, and drives the car 5 to fall through the L-shaped fixed connecting plate 4. When the L-shaped fixed connecting plate 4 hits the first buffer plate 15, the force will be applied to the load-bearing plate 13 through the first buffer spring 14, and then the load-bearing plate 13 will transmit the force to the push plate 12. When the push plate 12 is impacted, the sliding plate 10 will push the extrusion fixing rod 8 to slide on the outer surface of the first spring 9, thereby achieving uniform dispersion of the impact force.

[0028] When the L-shaped fixed connecting plate 4 hits the first buffer plate 15, the force will be applied to the bearing plate 13 through the first buffer spring 14, and then the bearing plate 13 will transmit the force to the push plate 12. When the push plate 12 is impacted, the sliding plate 10 will push the extrusion fixing rod 8 to slide on the outer surface of the first spring 9. Compared with the traditional device, this device allows trainees to personally experience the actual situation when the elevator fails, including the vibration and shaking when the elevator falls or collides. At the same time, when a simulated elevator failure occurs, the buffer device can effectively absorb and reduce the impact force between the elevator car and other components, avoid equipment damage caused by hard collision, and protect the personal safety of trainees.

[0029] Among them, a connecting plate 26 is fixedly clamped on the top of the car 5, and cylinder frames 16 are fixedly installed on the left and right sides of the top connecting plate 26 inside the car 5, and a C-shaped plate 17 is fixedly installed between the two cylinder frames 16. Cylinders 18 are fixedly installed inside the cylinder frames 16 and the cylinders 18 extend out of the cylinder frames 16, and a first telescopic rod 19 is fixedly installed on the inner side of the C-shaped plate 17. A connecting circular plate 22 is fixedly installed on the top of the first telescopic rod 19 and the cylinder 18 extends to above the top of the connecting circular plate 22. The outer surface of the first telescopic rod 19 is movably sleeved with a third spring 21 below the connecting circular plate 22, and an induction mechanism is fixedly installed on the inner side of the L-shaped fixed connecting plate 4.

[0030] When the sensing mechanism senses a sudden change in temperature, the cylinder 18 will shrink rapidly. When the cylinder 18 shrinks rapidly, the squeezing force on the top of the connecting circular plate 22 will disappear instantly. Then, the instantaneous force of the elastic recovery effect of the third spring 21 will push the connecting circular plate 22 to directly hit the connecting plate 26, thereby knocking the connecting plate 26 open.

[0031] The cylinder 18 contracts rapidly, and the squeezing force on the top of the connecting circular plate 22 disappears instantly. Then, the instantaneous force of the elastic recovery effect of the third spring 21 pushes the connecting circular plate 22 to directly impact the connecting plate 26, so that the connecting plate 26 is knocked open. Compared with the traditional device, when the trainees are in a simulated elevator trapped environment, the sufficient oxygen supply helps to keep the mind clear and avoid panic, anxiety and other emotions due to lack of oxygen.

[0032] Among them, a base plate 30 is fixedly installed on the outer surface of the first fixed plate 6 and the base plate 30 is located in the middle of the two groups of second fixed plates 7, a second telescopic rod 31 is fixedly installed on the top of the base plate 30 and the second telescopic rod 31 is fixedly connected to the supporting plate 13, and a second spring 20 is movably sleeved on the outer surface of the second telescopic rod 31 and one end of the second spring 20 is fixedly connected to the supporting plate 13.

[0033] When the first buffer plate 15 is hit, the first buffer spring 14 will transmit force to the bearing plate 13, and then the bearing plate 13 will transmit force to the second telescopic rod 31, and the second spring 20 will also be squeezed, thereby achieving a secondary buffering effect.

[0034] When the first buffer plate 15 is hit, the first buffer spring 14 will transmit the force to the bearing plate 13, and then the bearing plate 13 will transmit the force to the second telescopic rod 31, and the second spring 20 will also be squeezed. Compared with the traditional device, this device can effectively assist the main buffer device when the elevator simulates emergency situations such as loss of control or falling, reduce the possibility of trainees being injured due to collision, vibration, etc., and create a safe training environment.

[0035] The sensing mechanism includes a temperature sensor 23 fixedly mounted on the inner side of an L-shaped fixed connecting plate 4 , and a plc controller 24 fixedly mounted on the bottom outer surface of the cylinder frame 16 .

[0036] When the temperature sensor 23 senses the high temperature generated by the rapid fall of the L-shaped fixed connecting plate 4 and the friction of the second lifting component 3, it will transmit a signal to the PLC controller 24 so that the connecting plate 26 can be opened smoothly. During normal operation, the temperature is normal and the temperature sensor 23 will not be triggered.

[0037] The outer surface of the roller 11 is fixedly sleeved with a push plate 12 , and the roller 11 passes through the push plate 12 and is rotatably connected to the inner walls of both sides of the sliding plate 10 .

[0038] The roller 11 penetrates the pushing plate 12 and the inner walls on both sides of the sliding plate 10 to be rotatably connected, thereby effectively maintaining the stable operation of the device and avoiding jamming that affects the operation of the device.

[0039] A second buffer spring 25 is movably sleeved on the outer surface of the lower side of the second lifting assembly 3 , and a limiting block 29 is fixedly installed on the other end of the second lifting assembly 3 .

[0040] When the bottom surface of the L-shaped fixed connecting plate 4 contacts the second buffer spring 25, the second buffer spring 25 will be elastically deformed and will effectively relieve the force. The limit block 29 can effectively prevent the second buffer spring 25 from falling off.

[0041] Among them, a fourth spring 27 is fixedly installed on the inner bottom of the elevator shaft 1 and the fourth spring 27 is in a linear array shape, and the other end of the fourth spring 27 is fixedly connected to the second buffer plate 28.

[0042] The other end of the fourth spring 27 is fixedly connected with a second buffer plate 28. When all protective devices of the elevator are damaged, the car 5 will directly impact the second buffer plate 28, and the second buffer plate 28 will squeeze the fourth spring 27. Since the fourth spring 27 will undergo elastic deformation to unload the force, the damage is minimized.

[0043] The first buffer springs 14 are fixedly mounted on the outer surface of the bearing plate 13 , and the first buffer springs 14 are fixedly connected to the first buffer plate 15 in a linear array.

[0044] The first buffer springs 14 are fixedly connected to the first buffer plate 15 in a linear array, so that the impact force brought by the L-shaped fixed connecting plate 4 can be more fully and evenly borne.

[0045] Working principle and usage process:

[0046] When safety experience training is required, the first lifting component 2 is started. At this time, the first lifting component 2 simulates the falling safety experience according to the setting, and drives the car 5 to fall through the L-shaped fixed connecting plate 4. When the L-shaped fixed connecting plate 4 hits the first buffer plate 15, the force will be applied to the load-bearing plate 13 through the first buffer spring 14, and then the load-bearing plate 13 will transmit the force to the push plate 12. When the push plate 12 is impacted, the sliding plate 10 will push the extrusion fixing rod 8 to slide on the outer surface of the first spring 9, thereby achieving uniform dispersion of the impact force.

[0047] When the sensing mechanism senses a sudden change in temperature, the cylinder 18 will shrink rapidly. When the cylinder 18 shrinks rapidly, the squeezing force on the top of the connecting circular plate 22 will disappear instantly. Then, the instantaneous force of the elastic recovery effect of the third spring 21 will push the connecting circular plate 22 to directly hit the connecting plate 26, thereby knocking the connecting plate 26 open.

[0048] When the first buffer plate 15 is hit, the first buffer spring 14 will transmit force to the bearing plate 13, and then the bearing plate 13 will transmit force to the second telescopic rod 31, and the second spring 20 will also be squeezed, thereby achieving a secondary buffering effect.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
