Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to a highly reliable heavy-duty freight elevator frame structure. Background Technology
[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° from the vertical. There are also escalators, where the steps are mounted on a continuous track and run continuously. They are commonly known as moving walkways or automatic elevators. They are fixed lifting devices that serve designated floors. Vertical elevators have a car that runs between at least two rigid guide rails that are vertical or have an inclination angle of less than 15°. Freight elevators are a type of elevator.
[0003] An elevator car frame structure typically includes a car top structure and a car bottom structure. The car frame is the supporting frame of the elevator car, composed of core components such as the upper beam, columns, and bottom beam. The car top and car bottom structures are the connecting and load-bearing components between the car frame and other parts of the car. During use, some freight elevators often need to carry heavy objects. During operation, some car frames may experience significant vibrations in the car due to the large and concentrated pressure on the car bottom support, which reduces the safety of the car.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1:
[0029] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a highly reliable heavy-duty freight elevator frame structure, including an upper beam 1. The upper beam 1 has a car top wheel assembly 2 inside it. The bottom of the upper beam 1 is fixedly connected to a vertical beam 3. Inclined plates 4 are fixedly connected to both sides of the vertical beam 3. A buffer assembly 5 is provided on one side of the vertical beam 3. By setting the buffer assembly 5, the pressure on the car bottom bracket 6 can be reduced under the action of the buffer assembly 5, so that the device can remain stable during normal operation and prevent it from shaking excessively.
[0030] The buffer assembly 5 includes a buffer plate 501 disposed on one side of the upright beam 3. Bolts 502 are threadedly connected to the inside of the buffer plate 501. A reinforcing plate 503 is disposed at the bottom of the buffer plate 501. A conical rubber pad 504 is disposed at the top of the reinforcing plate 503. A connecting pipe 505 is fixedly connected to the bottom of the buffer plate 501.
[0031] Under the action of the buffer plate 501, the pressure generated by the heavy object can be transmitted. At the same time, under the action of multiple buffer pads 7, the high-frequency micro-vibration of the device can be absorbed. When the buffer plate 501 is under a certain pressure, the pressure can be transmitted to the inside of the connecting pipe 505, so that the pressure can be transmitted to various positions of the reinforcing plate 503 through the connecting pipe 505, thereby dispersing the pressure and preventing it from being concentrated, which would cause large amplitude vibration during the operation of the device.
[0032] Example 2:
[0033] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0034] Specifically, a car bottom bracket 6 is fixedly connected to one side of the upright beam 3, the outer side of the bolt 502 is threadedly connected to the inside of the car bottom bracket 6, the top of the reinforcing plate 503 is fixedly connected to the bottom of the car bottom bracket 6, and a lower beam 18 is fixedly connected to one side of the car bottom bracket 6.
[0035] The bolt 502 connects the car bottom bracket 6 to the buffer plate 501. The bolt 502 is made of high-strength material.
[0036] Specifically, a buffer pad 7 is provided on the outside of the bolt 502, and a first steel plate 8 is fixedly connected to the bottom of the buffer pad 7.
[0037] The buffer pad 7 can absorb the micro-vibrations of the device, thereby making the device stable. At the same time, the first steel plate 8 and the second steel plate 9 can make the connection between the buffer pad 7 and the buffer plate 501 stable.
[0038] Specifically, the top of the buffer pad 7 is fixedly connected to the second steel plate 9, the outside of the bolt 502 is provided with a protective tube 10, and the top of the first steel plate 8 is fixedly connected to the bottom of the car bottom bracket 6.
[0039] The protective tube 10 can protect the bolt 502, preventing it from cracking during long-term use, thus ensuring a stable connection between the buffer plate 501 and the car bottom bracket 6.
[0040] Specifically, a butterfly spring 11 is welded to the bottom of the conical rubber pad 504, and the bottom of the butterfly spring 11 is welded to the top of the reinforcing plate 503.
[0041] The pressure transmitted by the conical rubber pad 504 can be dispersed under the action of the butterfly spring 11.
[0042] Specifically, a spring 12 is welded to the top of the inner cavity of the connecting pipe 505, and a fixing rod 13 is welded to the bottom of the spring 12.
[0043] Under the action of spring 12, the pressure on the connecting pipe 505 can be transmitted, and under the elastic force of spring 12, the connecting pipe 505 can be reset.
[0044] Example 3:
[0045] Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0046] Specifically, a connecting rod 14 is rotatably connected to the outside of the connecting pipe 505, and a connecting seat 15 is rotatably connected to the end of the connecting rod 14 away from the connecting pipe 505.
[0047] When the connecting pipe 505 moves, it can drive the multiple connecting rods 14 on its outer side to move. In turn, when the connecting rods 14 move, they can drive the connecting seat 15 to move, so that the movement of the connecting seat 15 can be transmitted to the damper 17. At the same time, the pressure borne by the connecting pipe 505 can be transmitted to various positions of the reinforcing plate 503.
[0048] Specifically, the reinforcing plate 503 has a placement groove 16 inside, and the inner wall of the placement groove 16 is slidably connected to the outer side of the connecting seat 15.
[0049] The placement groove 16 helps to keep the movement of the connecting seat 15 stable.
[0050] Specifically, a damper 17 is fixedly connected to one side of the connecting seat 15, and the number of connecting seats 15 and connecting rods 14 is set to four.
[0051] Under the action of multiple dampers 17, the pressure transmitted through the connecting rod 14 and the connecting seat 15 can be weakened, thereby reducing the pressure borne by the buffer plate 501 and the reinforcing plate 503, and preventing stress concentration.
[0052] Specifically, the bottom of the fixing rod 13 is fixedly connected to the top of the reinforcing plate 503, and the inner wall of the connecting pipe 505 is slidably connected to the outer side of the fixing rod 13.
[0053] When the connecting pipe 505 shows a tendency to move, it can be moved on the outside of the fixing rod 13 to prevent the connecting pipe 505 from tilting.
[0054] When this structure is used to load heavy objects, the buffer plate 501 bears a large pressure. The pressure is transmitted to the connecting pipe 505 through the various buffer pads 7. The buffer pads 7 can partially reduce the pressure on the buffer plate 501 and absorb the high-frequency micro-vibrations of this structure. After the pressure is transmitted to the connecting pipe 505, the connecting pipe 505 can slide on the outside of the fixed rod 13. This movement of the connecting pipe 505 can drive the movement of multiple connecting rods 14, which in turn can drive the connecting seat 15 to slide inside the placement groove 16. When the connecting seat 15 moves, the pressure can be transmitted to the damper 17. Under the action of multiple dampers 17, the pressure transmitted by the connecting rods 14 and the connecting seat 15 can be reduced, and the pressure on the reinforcing plate 503 can be distributed. This prevents stress concentration on the reinforcing plate 503 and the buffer plate 501, thus ensuring the stability of the device during normal operation and preventing excessive vibration amplitude, which would reduce the service life of the device.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
