Abstract
Description
Technical Field
[0001] This utility model relates to elevators, specifically to a compact elevator car bottom structure. Background Technology
[0002] With rapid societal development, land is becoming increasingly scarce, and the phenomenon of "every inch of land is worth its weight in gold" is commonplace in modern cities. The same applies to elevators; finding ways to make shafts smaller and elevators larger is a growing and increasingly important requirement given the ever-increasing value of land. For example, conventional elevators already in operation on the market have ample dimensional allowances in all dimensions, rather than adhering to the limits required by national standards.
[0003] Currently, the design, manufacturing, and installation of elevators do not involve the same high level of technological requirements as automobiles. We often allow for larger tolerances to reduce various processing and installation problems and difficulties. However, this requirement is even more urgent for villa elevators because the shaft space is very small. Maximizing the car size is a pressing need for every manufacturer. Therefore, we propose a compact elevator car bottom structure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a compact elevator car bottom structure, which solves the problem of the small space in the current villa elevator shaft and maximizes the size of the car.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a compact elevator car bottom structure, including a bottom plate, side plates, connecting plates, shock-absorbing rubber, support plates, connecting beams, mounting plates, and a car return rope pulley. The bottom plate is fixedly connected to the front and rear sides of its bottom end, and the two side plates are fixedly connected to the left and right sides of their respective sides. The bottom ends of the two connecting plates are fixedly connected to the support plates via shock-absorbing rubber. The bottom ends of the two support plates are fixedly connected to the front and rear sides of their respective sides, and the two connecting beams are fixedly connected to the three mounting plates between the two support plates. The two mounting plates on the left side are rotatably connected to the car return rope pulley via a rotating shaft.
[0006] Based on the above scheme, the car return rope wheel is provided in two parts, and the two car return rope wheels are installed at the front and rear ends of the mounting plate.
[0007] Based on the above scheme, the front and rear ends of the support plate are respectively fixedly connected with pull lugs.
[0008] Based on the above scheme, a protective plate is installed at the bottom of the car return rope wheel, and the protective plate is fixedly connected to the mounting plate by bolts.
[0009] Based on the above scheme, a sill is fixedly connected to the left end of the base plate.
[0010] Compared with the prior art, the advantages of this utility model are as follows: a compact elevator car bottom structure adopts a new structure to optimize the elevator car bottom, which can maximize the car size, integrate the mounting plate and the car return rope wheel into one unit, minimize the pit requirement, retain the shock-absorbing rubber of the car bottom, and simultaneously reduce the pit to the limit, thereby reducing the diameter of the car return rope wheel and lowering the cost. This utility model has a simple and reasonable structure, is easy to install, has low manufacturing cost, and is highly practical. Attached Figure Description

[0016] Reference Figures 1 to 2It is known that a compact elevator car bottom structure includes a bottom plate 1, side plates 2, connecting plates 3, shock-absorbing rubber 4, support plates 5, connecting beams 6, mounting plates 7, and a car return rope pulley 8. The bottom plate 1 is fixedly connected to the front and rear sides of its bottom end with side plates 2, and the two side plates 2 are fixedly connected to the left and right sides of their respective sides with connecting plates 3. The bottom ends of the two connecting plates 3 are fixedly connected to support plates 5 via shock-absorbing rubber 4. The shock-absorbing rubber 4 can play a role in shock absorption for the entire elevator car bottom. The bottom ends of the two support plates 5 are fixedly connected to the front and rear sides with connecting beams 6, and the two connecting beams 6 are fixedly connected to three mounting plates 7 between the two support plates 5. The two mounting plates 7 on the left side are rotatably connected to the car return rope pulley 8 via a rotating shaft 12. The car return rope pulley 8, mounting plates 7, and connecting beams 6 can be installed as a whole first, and then installed as a whole under the bottom plate 1, which is simple and convenient to install.
[0017] Two car return rope pulleys 8 are provided, and the two car return rope pulleys 8 are installed at the front and rear ends of the mounting plate 7. The car return rope pulleys 8 and the mounting plate 7 can be installed as a whole, which can be easily installed under the bottom plate. The front and rear ends of the support plate 5 are respectively fixedly connected with pull ears 9, which facilitate the installation of other pull ropes. The bottom of the car return rope pulley 8 is equipped with a protective plate 10, which is fixedly connected to the mounting plate 7 by bolts. The protective plate 10 can protect the car return rope pulley 8. The left end of the bottom plate 1 is fixedly connected with a sill 11, which can protect the bottom plate 1 and improve its appearance.
[0018] The principle and advantages of this utility model: A compact elevator car bottom structure adopts a new structure that optimizes the elevator car bottom structure. The mounting plate 7 and the car return rope wheel 8 are installed as one unit, making installation and disassembly simple and convenient. It minimizes the pit requirement, while retaining the shock-absorbing rubber 4 at the bottom of the car, which can play a good role in shock absorption. The pit is also reduced to the limit, and the diameter of the car return rope wheel 8 is reduced, thus reducing costs and maximizing the car size. This utility model has a simple and reasonable structure, is easy to install, has low manufacturing cost, and is suitable for widespread use.
