However, the existing devices cannot automatically buffer the elevator when it descends rapidly, resulting in a relatively high risk when the elevator breaks down and posing a great potential safety hazard.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0016] 2.

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0023] Referring to Figures 1 - 4 , a top platform device includes:
[0024] A bottom platform 1, and a top platform 11 is installed above the bottom platform 1 through a plurality of support columns;
[0025] A transportation mechanism 2 for transporting viewing personnel, including a plurality of limiting rods 21 installed on the bottom platform 1, an elevator 22 is slidably installed on the plurality of limiting rods 21, a motor 23 is provided below the top platform 11, a winding roller 24 is provided on the output shaft of the motor 23, a traction rope 25 is wound on the winding roller 24, a rotating rod 26 is rotatably installed above the top platform 11 through a fixing plate, a guide wheel 27 is provided on the rotating rod 26, and the traction rope 25 is fixedly connected to the upper part of the elevator 22 after being guided by the guide wheel 27.
[0026] During actual use, by driving the winding roller 24 to rotate through the motor 23, the length of the traction rope 25 can be changed by winding or extending the traction rope 25 on the winding roller 24. After being guided by the guide wheel 27, the lifting of the elevator 22 can be controlled, and the operation is very convenient. This is a mature technology that has already existed and will not be elaborated here too much.
[0027] Buffer mechanism 3, the buffer mechanism 3 is used to automatically lock the elevator 22 in case of a failure of the elevator 22, and includes an extension rod 31 installed on the rotating rod 26. A rotating ring 32 is installed on the extension rod 31 through a connecting rod. A fixed ring 33 is installed on the top floor platform 11 through a fixed column. The rotating ring 32 is hermetically and rotatably installed on the inner wall of the fixed ring 33. A plurality of fixed sleeves 34 are provided on the inner wall of the rotating ring 32. A sliding rod 35 is hermetically and slidably installed in each fixed sleeve 34. A counterweight 36 is provided on the part of each sliding rod 35 extending outside the fixed sleeve 34. Each sliding rod 35 is elastically connected to the inside of the rotating ring 32 through a spring 37. A buffer ring 38 is provided on the top floor platform 11. A plurality of abutting sleeves 39 are provided on the inner wall of the buffer ring 38. An abutting rod 310 is hermetically and slidably installed in each abutting sleeve 39. An abutting arc piece 311 is provided at one end of each abutting rod 310 close to the traction rope 25.
[0028] Among them, the inside of the rotating ring 32 is communicated with the inside of the fixed ring 33 through a liquid inlet and an annular liquid inlet groove.
[0029] Among them, the inside of the fixed ring 33 is communicated with the inside of the buffer ring 38 through a connecting pipe.
[0030] Among them, the fixed sleeve 34 and the abutting sleeve 39 are respectively communicated with the inside of the rotating ring 32 and the buffer ring 38.
[0031] When the sliding rod 35 moves away from the extension rod 31 under the action of centrifugal force, the hydraulic oil in the fixed sleeve 34 is squeezed into the rotating ring 32, making the hydraulic oil in the rotating ring 32 excessive, and the excessive hydraulic oil is transported to the fixed ring 33 through the liquid inlet and the annular liquid inlet groove. The hydraulic oil in the fixed ring 33 transports the excessive hydraulic oil to the buffer ring 38 through the connecting pipe, so that the hydraulic oil in the abutting sleeve 39 squeezes and pushes the abutting rod 310, and then the abutting arc piece 311 can contact the traction rope 25.
[0032] Among them, the rotating ring 32, the fixed ring 33 and the buffer ring 38 are filled with hydraulic oil. Due to the characteristic that the hydraulic oil is difficult to compress, when the abutting arc piece 311 contacts the traction rope 25, the abutting arc piece 311 can be kept in close contact with the traction rope 25, so as to ensure that the traction rope 25 can slow down the speed of extending from the winding roller 24 under the action of friction.
[0033] In the prior art, when the elevator 22 malfunctions, it will quickly descend under the action of gravity. However, the existing devices cannot automatically buffer the elevator 22 when it descends rapidly, resulting in a relatively high risk when the elevator 22 malfunctions and posing a significant potential safety hazard. To address this problem, the present utility model is provided with a buffer mechanism 3. When the elevator 22 malfunctions and rapidly descends under the action of gravity, the traction rope 25 will quickly extend from the winding roller 24. Under the action of friction, it drives the guide wheel 27 to rotate rapidly, further driving the rotating rod 26 and the extension rod 31 to rotate rapidly, causing the rotating ring 32 to rotate rapidly. Under the action of centrifugal force, the sliding rod 35 moves away from the extension rod 31, squeezing the hydraulic oil in the fixed sleeve 34 into the rotating ring 32. Further, through the fixed ring 33 and the connecting pipe, the hydraulic oil is conveyed into the buffer ring 38, enabling the abutting rod 310 in the abutting sleeve 39 to extend, and abutting the abutting arc plate 311 against the traction rope. Through the friction between the abutting arc plate 311 and the traction rope 25, the extending speed of the traction rope 25 is reduced, thereby weakening the descending speed of the elevator 22 and reducing the harm to the people in the elevator 22 when the elevator 22 malfunctions, greatly reducing the risk.
[0034] The functional principle of the present utility model can be elaborated through the following operating modes:
[0035] During normal use, the winding roller 24 is driven to rotate by the motor 23, causing the traction rope 25 to wind or extend on the winding roller 24, changing the length of the traction rope 25. After being guided by the guide wheel 27, the lifting and lowering of the elevator 22 are controlled. At this time, the descending speed of the elevator 22 is relatively slow, the rotating speed of the rotating ring 32 is relatively slow, and the centrifugal force is not sufficient to drive the buffer mechanism 3 to operate;
[0036] When the elevator 22 malfunctions and descends rapidly, the traction rope 25 will quickly extend from the winding roller 24. Under the action of friction, it drives the guide wheel 27 to rotate rapidly, driving the rotating rod 26 and the extension rod 31 to rotate rapidly. Under the action of centrifugal force, the sliding rod 35 moves away from the extension rod 31, squeezing the hydraulic oil in the fixed sleeve 34 into the rotating ring 32. Through the fixed ring 33 and the connecting pipe, the hydraulic oil is conveyed into the buffer ring 38, enabling the abutting rod 310 in the abutting sleeve 39 to extend, and abutting the abutting arc plate 311 against the traction rope. Through the friction between the abutting arc plate 311 and the traction rope 25, the extending speed of the traction rope 25 is reduced, weakening the descending speed of the elevator 22.
[0037] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
