[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Figure 1It is a schematic diagram of the overall structure of the utility model. The elevator car reinforcement device includes a concave steel plate 1 and a second connecting plate 4. The concave steel plate 1 is coated on the lower end of the outside of the elevator car to protect the bottom and surroundings of the elevator car, and mounting grooves 11 are provided on both sides of the bottom end of the concave steel plate 1. A first connecting plate 2 is movably connected in the mounting groove 11. The first connecting plate 2 can move up and down in the mounting groove 11. A plurality of elastic connectors 17 are connected between the top of the first connecting plate 2 and the top of the mounting groove 11. The elastic connector 17 is a combination of a rubber column and a spring. The rubber column is coated on the outside of the spring. When the bottom of the first connecting plate 2 is impacted and moves upward into the mounting groove 11, the elastic connector 17 is compressed to play a certain buffering role, thereby reducing the impact force on the elevator car, and when the impact force disappears, the elastic connector 17 pushes the first connecting plate 2 to return to its initial position, thereby playing a resetting role.

[0032] A first reinforcing steel plate 3 is fixedly installed at the bottom end of the first connecting plate 2, and an upwardly arched elastic sheet 9 is installed on the upper end surface of the first reinforcing steel plate 3. The elastic sheet 9 deforms under pressure and plays a certain buffering role, thereby reducing the damage to the car.

[0033] Grooves 12 are symmetrically formed on both sides of the installation slot 11 . A lifting assembly is disposed in the groove 12 . The lifting assembly is used to move the first connecting plate 2 vertically to reduce the occurrence of skewing of the first connecting plate 2 during the buffering process.

[0034] Secondly, the second connecting plate 4 is fixedly connected to the bottom end of the first connecting plate 2, and a second reinforcing steel plate 5 that can move up and down is provided below the first reinforcing steel plate 3 and between the two second connecting plates 4, and a third reinforcing steel plate 7 is provided below the second reinforcing steel plate 5. Arc guard plates 10 are connected to both sides of the third reinforcing steel plate 7, and a circular arc transition is formed at the connection between the third reinforcing steel plate 7 and the arc guard plate 10, and a plurality of first buffer springs 8 are evenly installed between the first reinforcing steel plate 3 and the second reinforcing steel plate 5, and a plurality of buffer parts 6 are installed between the second reinforcing steel plate 5 and the third reinforcing steel plate 7.

[0035] Through the above technical solution:

[0036] When the car falls accidentally, the third reinforcing steel plate 7, the second reinforcing steel plate 5, the first reinforcing steel plate 3 and the concave steel plate 1 at the bottom of the car can effectively improve the overall strength of the lower section of the car, and through the cooperation of structures such as elastic sheets 9 and buffers 6, the pressure between the car and the bottom of the elevator shaft during falling can be effectively buffered, thereby improving the protection of the car and the people inside.

[0037] In addition, the setting of the lifting assembly enables the first connecting plate 2 to move vertically in a straight line, which can effectively reduce the occurrence of skewness of the first connecting plate 2 during the vertical movement, so as to ensure the strengthening effect of the car.

[0038] Among them, see Figure 1 and Figure 4 As shown, a plurality of guide plates 16 are symmetrically connected to both ends of the second reinforcing steel plate 5, a plurality of guide openings 15 are opened on the second connecting plate 4, the guide plates 16 pass through the guide openings 15, and the height of the guide openings 15 is 3-6 times the thickness of the guide plates 16, and the two sides of the guide plates 16 and the inner side clearances of the guide openings 15 are matched, so that the guide plates 16 can move up and down a certain distance in the direction of the guide openings 15.

[0039] Specifically, when the second reinforcing steel plate 5 moves up and down, the guide plate 16 moves up and down along the guide opening 15, which can reduce the occurrence of skewness of the second reinforcing steel plate 5 during the vertical movement, so as to ensure the reinforcement effect of the car.

[0040] See also Figure 2 As shown, the lifting assembly includes:

[0041] At least two gears 13, the two gears 13 are vertically distributed and rotatably installed in the groove 12;

[0042] The rack 14 is installed on the side of the first connecting plate 2 , and the rack 14 is meshed with the gear 13 .

[0043] Through the above, when the first connecting plate 2 is pressed and moves upward, the rack 14 moves upward linearly along the rotating gear 13 to ensure the linearity of the movement of the first connecting plate 2.

[0044] In a specific embodiment of the present invention, refer to Figure 3 As shown, the buffer member 6 comprises:

[0045] The cylinder 61 is mounted on the upper end surface of the third reinforcing steel plate 7, and a receiving groove is provided inside the cylinder 61, and the top end of the cylinder 61 is open and connected to the receiving groove;

[0046] A second buffer spring 63, the second buffer spring 63 is arranged at the bottom of the accommodating groove;

[0047] The connecting column 62 is movably connected in the accommodating groove, and both ends of the connecting column 62 are respectively connected to the top end of the second buffer spring 63 and the lower end surface of the second reinforcing steel plate 5.

[0048] As mentioned above, when the third reinforcing steel plate 7 contacts the bottom of the elevator shaft, the cylinder 61 is forced to move upward, the second buffer spring 63 is compressed, and the cylinder 61 moves linearly along the connecting column 62. During the buffering process, the up and down linear movement of the third reinforcing steel plate 7 can be limited to a certain extent to ensure the buffering and reinforcement effect of the car.
