Description

Technical Field

[0001] This utility model relates to the field of elevator car components, and in particular to an elevator car bottom structure. Background Technology

[0002] With the increasing number of high-rise buildings, elevators are becoming more and more widely used. As a crucial component of the elevator car, the performance of the elevator car floor directly affects the elevator's operational safety, stability, and comfort. Currently, traditional elevator car floor structures have several problems, such as poor shock absorption, low security when connected to the building walls, complex maintenance, and the fact that the car floor deflector is usually arranged vertically, meaning it's located in the center of the car floor. This layout typically requires sufficient space in the center of the car floor to accommodate the deflector and its related components, which to some extent limits the expansion of car size and the effective utilization of shaft space. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing an elevator car bottom structure.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an elevator car bottom structure, including a car bottom plate, a car bottom bracket, shock-absorbing pads, a sill, a sill bracket, a foot guard, a foot guard bracket, a car bottom anti-cord pulley, and an anti-cord pulley bracket. Several shock-absorbing pads are installed on the top of both sides of the car bottom bracket. The car bottom plate is installed on top of the shock-absorbing pads. The sill bracket is installed on one side of the car bottom bracket, and the sill is installed on top of the sill bracket. The foot guard bracket is installed at the bottom of the car bottom bracket near the sill, and the foot guard is installed on the foot guard bracket. The anti-cord pulley bracket is installed obliquely at the bottom of the car bottom bracket. A pair of car bottom anti-cord pulleys are installed on both sides of the bottom of the anti-cord pulley bracket. Mounting holes are provided on both sides and the rear of the car bottom plate. The sides and rear of the car bottom plate are inserted into the car wall, and the front side is seated and fixed by bolts.

[0005] Specifically, the shock-absorbing pads are located at the top front, rear, and middle of both sides of the car bottom bracket.

[0006] Specifically, the car floor is C-shaped on both sides, and the front and rear ends of the car floor are provided with a groove-shaped first reinforcing rib, the middle is provided with several Z-shaped second reinforcing ribs, and the inner wall of the first reinforcing rib adjacent to the sill is provided with several third reinforcing ribs. The outer walls of the first reinforcing rib and the C-shaped bend are provided with mounting holes, and are bolted to the car wall through the mounting holes.

[0007] In particular, the sill bracket is inverted U-shaped, and the inner wall of the sill bracket is provided with several reinforcing plates. One side of the sill bracket is connected and fixed to the adjacent first reinforcing rib.

[0008] Specifically, the foot protection plate bracket includes a pair of first angle steels. The top of the first angle steels is provided with an inverted L-shaped connecting plate, which is bolted to the bottom of the adjacent first reinforcing rib. The first angle steels are inclined, and the bottom of the first angle steels is bolted with a second angle steel. The lower part of the foot protection plate is bolted to the second angle steel, and the upper part is bolted to the sill bracket.

[0009] The beneficial effects of this utility model are as follows: The car bottom plate of this utility model is inserted into the car wall on both sides and the rear side, and the front side is seated and fixed by bolts. It eliminates the need for holes in the top of the car bottom plate. The inserted wall connection is low-cost and easy to install. The seated connection on the front side effectively strengthens the sill and door opening sections. Furthermore, the inserted connection method is generally more stable than simple bolting because it relies not only on the force of the bolts but also on physical embedding to maintain its position, thus preventing safety hazards caused by loose bolts. When maintenance or component replacement is required, the inserted design typically does not require disassembling a large number of bolts, making maintenance more convenient. The installation of shock-absorbing pads increases stability and comfort, improving the comfort of elevator operation. The inclined arrangement of the car bottom anti-cord sheave allows for more flexible adaptation to different shaft conditions, reduces the need for specific shaft dimensions, and allows for the installation of larger cars in the same size shaft, not only improving the utilization of shaft space but also providing more possibilities for architectural design.

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1-7 As shown, an elevator car bottom structure includes a car bottom plate 1, a car bottom bracket 2, shock-absorbing pads 3, a sill 4, a sill bracket 5, a foot guard 6, a foot guard bracket 7, a car bottom anti-cord pulley 8, and an anti-cord pulley bracket 9. Several shock-absorbing pads 3 are installed on the top of both sides of the car bottom bracket 2, and the car bottom plate 1 is installed on top of the shock-absorbing pads 3. The shock-absorbing pads 3 are located at the front end, rear end, and middle of the top of both sides of the car bottom bracket 2. The installation of the shock-absorbing pads 3 can increase stability and comfort, improving the comfort of elevator operation. The car bottom bracket 2 can be made of high-strength steel plate bent into shape and is installed below the shock-absorbing pads 3 to support the car bottom and connect other components.

[0021] The car floor plate 1 is inserted into the car wall on both sides and the rear side, and seated and fixed at the front side with bolts. The car floor plate 1 has C-shaped bends on both sides. The front and rear ends of the car floor plate 1 are provided with grooved first reinforcing ribs 10, and the middle is provided with several Z-shaped second reinforcing ribs 11. The inner wall of the first reinforcing rib 10 adjacent to the sill 4 is provided with several third reinforcing ribs 12. The first reinforcing rib 10 and the outer wall of the C-shaped bend are provided with mounting holes, and are bolted to the car wall through the mounting holes. The setting of the first reinforcing ribs 10, the second reinforcing ribs 11 and the third reinforcing ribs 12 makes the car floor strong and the structure stable. It is inserted into the car wall on the left, right and rear sides, and seated at the front side. It does not require opening holes at the top of the car floor plate 1. The insertion into the wall has the characteristics of low cost and convenient installation. The seated connection at the front side can effectively strengthen the sill 4 and the door opening part. The structure formed by the C-shaped bend provides additional mechanical strength, helps to distribute the load and improve the stability of the entire car structure. This design can also reduce the impact of vibrations generated during elevator operation.

[0022] The sill bracket 5 is installed on one side of the car bottom bracket 2, and the sill 4 is installed on the top of the sill bracket 5. The sill bracket 5 is inverted U-shaped, and the inner wall of the sill bracket 5 is provided with several reinforcing plates 13. One side of the sill bracket 5 is connected and fixed to the adjacent first reinforcing rib 10.

[0023] The foot protection bracket 7 is installed at the bottom of the car floor bracket 2 near the sill 4. The foot protection plate 6 is installed on the foot protection bracket 7. The foot protection bracket 7 includes a pair of first angle steels 14. The top of the first angle steels 14 is provided with an inverted L-shaped connecting plate 15, which is bolted to the bottom of the adjacent first reinforcing rib 10 through the connecting plate 15. The first angle steels 14 are inclined, and a second angle steel 16 is bolted to the bottom of the first angle steels 14. The lower part of the foot protection plate 6 is bolted to the second angle steel 16, and the upper part is bolted to the sill bracket 5. The foot protection bracket 7 is connected to the bottom of the car floor plate 1, providing a larger support angle and further strengthening the car door foot protection plate 6.

[0024] The return rope pulley bracket 9 is installed at an angle at the bottom of the car bottom bracket 2, and a pair of car bottom return rope pulleys 8 are installed on both sides of the bottom of the return rope pulley bracket 9. The angled arrangement of the car bottom return rope pulleys 8 can make more efficient use of the shaft space and maximize the car size.

[0025] The bottom plate 1 of this utility model is inserted into the car wall on both sides and the rear side, and seated and fixed by bolts on the front side. It eliminates the need for holes in the top of the bottom plate 1. The insertion-to-wall connection is cost-effective and easy to install. The seated connection on the front side effectively strengthens the sill 4 and the door opening section. Furthermore, the insertion-to-wall connection method is generally more stable than simple bolting because it relies not only on the force of the bolts but also on physical embedding to maintain its position, thus preventing safety hazards caused by loose bolts. When maintenance or component replacement is required, the insertion-to-wall design typically eliminates the need to disassemble a large number of bolts, making maintenance more convenient. The installation of the shock-absorbing pads 3 increases stability and comfort, improving the comfort of elevator operation.
