[0029] Please refer to Figures 1-2 , an elevator car top of the embodiment, wherein the elevator car top comprises:

[0030] The car top frame 1 comprises a car top frame body 11, a first connecting plate 12 and a first reinforcing rib 13. The first connecting plate 12 is arranged around the edge of the car top frame body 11, and the first reinforcing rib 13 is arranged inside the car top frame body 11 and connected with the car top frame body 11, and the thickness of the reinforcing rib 13 is less than the thickness of the car top frame body 11.

[0031] The car top cover plate 2 is arranged on the top of the car top frame 1.

[0032] The limiting device 3 is installed on the car top frame 1, and the limiting device 3 is used to be connected with the straight beam of the elevator.

[0033] The elevator roof further comprises a ceiling frame 4, which comprises a ceiling frame body 41, a second connecting sheet 42 and a second reinforcing rib 43. The second connecting sheet 42 is arranged around the edge of the ceiling frame body 41, and the second reinforcing rib 43 is arranged inside the ceiling frame body 41 and connected with the ceiling frame body 41. The thickness of the second reinforcing rib 43 is smaller than that of the ceiling frame body 41. The position and size of the second connecting sheet 42 are matched with those of the first connecting sheet 12, and the second connecting sheet 42 is used to be fixed with the first connecting sheet 12 by bolts.

[0034] The elevator roof further comprises a sound insulation board 7, which covers the position filled between the roof frame 1 and the roof cover plate 2.

[0035] Through the above structure, when the elevator is running, the roof is affected by the self-shaking or external vibration transmission, the noise is transmitted from the direction of the roof cover plate 2 or the limiting device 3 from the roof to the inside of the car. Since the roof frame body 11 of the roof frame 1 in the embodiment is provided with a sound insulation board 7 with a certain thickness between the roof cover plate 2, the sound insulation board 7 can be sound insulation cotton with mesh, etc., therefore, the vibration noise from the roof cover plate 2 at the top of the roof frame 1 is mostly absorbed by the sound insulation board 7 during operation. At the same time, since the ceiling frame 4 is arranged at the bottom of the roof frame 1, and the size of the roof frame 1 in the embodiment is matched with that of the ceiling frame 4, and the peripheral connection is realized by the cooperation of the first connecting sheet 12 and the second connecting sheet 42, therefore, most of the vibration or noise from the outside of the car between the roof frame 1 and the ceiling frame 4 can be isolated, and the fixed is more stable. Further, the roof frame 1 in the embodiment is arranged as a regular rectangular structure, the first reinforcing rib 13 inside is arranged as a plurality of beams filling the gap position of the roof frame body 11, which can enhance the structural strength of the roof frame 1 itself, and help to avoid vibration and abnormal sound. Similarly, the ceiling frame 4 in the embodiment is also arranged as a regular rectangular structure, the second reinforcing rib 43 inside is arranged as a plurality of beams filling the gap position of the ceiling frame body 41, which can enhance the structural strength of the ceiling frame 4 itself, and help to avoid vibration and abnormal sound. Specifically, the layout of the first reinforcing rib 13 and the second reinforcing rib 43 can be adjusted according to the actual size of the roof.

[0036] It is worth noting that in the above structure, the roof frame 1 and the ceiling frame 4 are substantially independent structures except that the peripheral frame is fixed by the cooperation of the first connecting sheet 12 and the second connecting sheet 42, and the limiting device 3 which may further transmit abnormal sound is arranged on the roof frame 1, so that the ceiling frame 4 directly facing the inside of the car has good sound insulation effect. The thickness gap of the first reinforcing rib 13 is used to place the sound insulation board 7.

[0037] Further, please refer to Figure 3 The limiting device 3 comprises a roof connecting piece 31, a straight beam connecting piece 32 and a plurality of buffer pads 33. The roof connecting piece 31 is installed on the roof frame 1 in the vertical direction (specifically, the edge beam of the roof frame body 11). The roof connecting piece 31 and the straight beam connecting piece 32 are provided with buffer pads 33 extending in the vertical direction. By means of the above structure, when the straight beam impacts the roof, the vibration in the vertical direction can be absorbed by the extrusion of the buffer pads 33 between the roof connecting piece 31 and the straight beam connecting piece 32, thereby greatly reducing the vibration in the vertical direction. Meanwhile, the limiting device further comprises a vertical connecting piece 34. A pair of vertical connecting pieces 34 are installed on the roof connecting piece 31 in the horizontal direction. The roof connecting piece 31 and the pair of vertical connecting pieces 34 are respectively provided with a plurality of buffer pads 33 facing the straight beam. Specifically, in this embodiment, the pair of vertical connecting pieces 34 are oppositely arranged and each is fixed with a buffer pad 33, so that the two buffer pads 33 connected with the vertical connecting pieces 34 form X-axis buffering of the straight beam. The roof connecting piece 31 on the adjacent side is also provided with two interval arranged buffer pads 33 to form Y-axis buffering of the straight beam. In combination with the above-mentioned buffer pads 33 extending in the vertical direction, the limiting device 3 in this embodiment realizes XYZ three-way buffering and has better shock absorption effect.

[0038] Further, please refer to Figure 1 The roof cover plate 2 is provided with a safety window 8 for opening outward in the vertical direction. Specifically, the safety window 8 can still be made of a middle layer filled with sound insulation board 7, so that the horizontal plane of the roof cover plate 2 forms a complete plane of the sound insulation board 7, thereby further improving the sound insulation effect while meeting the safety requirements.

[0039] Further, the elevator roof further comprises a traveling cable limiting piece 5 fixed on the outer wall of the roof frame body 11. Specifically, the traveling cable limiting piece 5 is provided in the form of a groove with a protruding edge to limit the traveling cable and play the function of pipeline organization and certain structural protection effect.

[0040] Further, the elevator roof further comprises a lifting ring 6. One end of the lifting ring 6 is installed on the roof frame body 11 and extends outward to the outside of the roof cover plate 2 in the vertical direction. Specifically, the number of the lifting ring 6 is four. The four lifting rings 6 are arranged in a rectangular distribution on the elevator roof. By means of the structure of the lifting ring 6, the installation of the roof frame 1 can be realized more easily. The four lifting rings 6 arranged in a rectangular distribution can provide better balance effect.

[0041] Specifically, please refer to Figure 1In the embodiment, a pair of fans 9 are also installed at the positions on both sides of the top of the car roof cover plate 2, the fans 9 are used to provide air exhaust and ventilation functions for the bottom car, and the two fans 9 are separately arranged on both sides of the safety window 8, so that the structural stability of the car roof cover plate 2 is ensured.
