Description

Technical Field

[0001] The invention relates to the technical field of railway vehicle dumper unloading, in particular to a multifunctional three-support point double-car dumper. Background Art

[0002] A car tipper is an efficient automated equipment used to tip over railway vehicles. On my country's railways, there are two types of vehicles, decoupled vehicles and non-decoupled vehicles, both in operation. Due to the different lengths of decoupled vehicles and non-decoupled vehicles, there is a problem of changing the length of the car tipper platform. Patent No. 200310105284.2 discloses a dual-purpose car tipper with a conversion platform, which uses the technology of a telescopic platform to solve the problem of changing the length of the platform of a single-car tipper. Patent No. 200810011061.2 discloses a dual-purpose car tipper, which solves the problem of changing the length of the platform of a large car tipper by connecting a long rotor mechanism in series with a short rotor mechanism. The technical solution has two supporting points for both the long rotor mechanism and the short rotor mechanism, and the entire car tipper has four supporting points. However, for a double-car tipper, the maximum length difference between two sections of different types of railway vehicles is less than 4 meters, and the series-connected short rotor mechanism is supported by two fulcrums, resulting in serious accumulation of materials when the tipper is unloading.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be clear that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0038] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.

The two second side beams 33 and the second platform beam 32 are distributed in a triangle, the second platform beam 32 is located at the bottom, and the two second side beams 33 are arranged in parallel and located at the top.

[0045] The first support ring 21 and the second support ring 22 are a closed O-shaped structure or a semi-closed C-shaped structure. In this embodiment, a semi-closed C-shaped structure is adopted.

[0046] The bottom of the first support ring 21 and the second support ring 31 has a support roller 7 installed on the civil engineering foundation 6;

[0047] A rotary drive device 1 is provided next to the long rotor mechanism 2. The rotary drive device 1 has a first output shaft 11. The first output shaft 11 is connected to the second output shaft 12 through a clutch 13. The first output shaft 11 and the second output shaft 13 are respectively provided with gears that match the external teeth of the first support ring 21 and the external teeth of the second support ring 31; the clutch 12 is used to connect or disconnect the first output shaft 11 and the second output shaft 13;

The guide plate is made of a material that is easy to slide, such as bronze.

[0049] The second platform beam 32 is provided with a driving unit 5 for driving the key 4 to move along the slideway at the location of the key 4. The driving unit 5 is a cylinder, an electro-hydraulic push rod or an electric lead screw.
