The safety, reliability, and comfort of elevators have become the focus of people's attention. As an important part of the elevator door system, the performance of the elevator sill directly affects the overall operation effect of the elevator. In high-rise buildings and places with a large flow of people, the elevator is used frequently, which puts higher requirements on the strength, wear resistance, and corrosion resistance of the elevator sill. Due to its excellent mechanical properties and good processing performance, cast iron sill has become an ideal choice to meet these requirements. After retrieval, the patent with the Chinese patent application number 202321488088.7 discloses a combined elevator cast iron sill, including that the sill at the elevator entrance and exit is made of cast iron, and the sill at non-entrance and exit is formed by bending sheet metal. The cast iron part of the sill and the sheet metal bending part of the sill are provided with mounting holes with the same axis and are jointly installed on the sill bracket. The sill bracket is fixed to the concrete wall through bracket fixing parts. The combined elevator cast iron sill in the above patent has the following deficiencies: it cannot effectively absorb the impact and vibration generated during the operation of the elevator, and cannot reduce the damage to elevator components and the impact of elevator operation on the building structure.

[0026] A combined elevator cast iron sill, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, it includes a cast iron sill groove 2. Nine equally spaced mounting holes 13 are provided at the bottom of the cast iron sill groove 2. An anti-slip abrasive layer 3 is fixedly connected to the top of the cast iron sill groove 2. A bracket 1 is movably connected to the mounting holes 13 at the bottom of the cast iron sill groove 2. An installation bracket 6 is welded to the bottom of the bracket 1. Two bracket mounting holes 10 are provided on one side of each installation bracket 6. A load-bearing rod 7 is welded inside the installation bracket 6.

[0027] During operation, first use a welding torch to weld the installation bracket 6 to the bracket 1 and weld the installation bracket 6 to the load-bearing rod 7. Then, splice the bracket 1 and the cast iron sill groove 2 with bolts according to the position of the mounting holes 13. When splicing, pay attention to centering. Install the assembled car to the car door, adjust the position to align, and then use bolts to align the bracket mounting holes 10 and splice with the wall. Thus, through the combination of the cast iron sill groove 2, the bracket 1 and the installation bracket 6, sufficient support is provided for the sill, the installation is simple, and there is no need to process various parts or drill holes anymore.

[0028] To ensure the fixation of the cast iron sill groove 2 and the car door during operation, as Figure 3 、 Figure 4 shown in the figure, it includes a shock-absorbing mechanism 5 fixedly connected to the inner wall of the cast iron sill groove 2. A limit protrusion 4 is fixedly connected to the top of the shock-absorbing mechanism 5. Telescopic limit blocks 11 are slidably connected to both sides of the limit protrusion 4. A guide groove 12 is provided at the top of the shock-absorbing mechanism 5.

[0029] During operation, when the bottom of the cast iron sill groove 2 is fixedly connected above the bottom of the bracket 1, the bottoms on both sides of the cast iron sill groove 2 are also just movably connected to the top ends on both sides of the bracket 1, forming a cube structure, making it more stable. Thus, the structure is simple and reasonable, easy to manufacture, and convenient for installation and maintenance. Therefore, it can provide support between the cast iron sill groove 2 and the car door, facilitating the entry and exit of passengers' wheelchairs or other small vehicles into and out of the car, reducing the impact of elevator operation on the building structure, and reducing the possibility of damage to the building due to elevator vibration.

[0030] To reduce the noise and vibration during the operation of the cast iron sill groove 2 and the car door, as Figure 2 、 Figure 5 shown in the figure, the shock-absorbing mechanism 5 includes a pressure plate 501, a spring 502 and a support plate 503. Nine pressure plates 501 are fixedly connected to the upper surface of the bottom of the cast iron sill groove 2. Nine springs 502 are fixedly connected to the top of each pressure plate 501. The support plate 503 is fixedly connected to the top of the nine springs 502. A soundproof pad 8 is fixedly connected to the bottom on one side of the cast iron sill groove 2. A shock-absorbing pad 9 is fixedly connected to one side of the bracket 1.

[0031] During operation, the car door starts running in the guide groove 12, maintains the correct running direction through the limit projection 4, and stops running at the telescopic limit block 11. The shock absorption mechanism 5 works throughout the process, pressing on the spring 502 through the pressure plate 501 and the support plate 503. The sound insulation pad 8 and the shock absorption pad 9 form an angle with the wall surface. Thus, the vibration and noise during the operation of the car door are reduced.

It can provide support between the cast iron sill groove 2 and the car door, facilitating the entry and exit of passengers' wheelchairs or other small vehicles into and out of the car, and reducing the vibration and noise during the operation of the car door. It can effectively absorb the impact and vibration generated during the operation of the elevator, reduce the damage to elevator components, and extend the service life of the elevator.
