Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicles, in particular to an air cylinder falling protection structure. Background Art

[0002] The air cylinder module is installed under the subway car body and is an important component of the braking system. The air cylinder module generally includes three air cylinders, each of which is fixed to the welded frame by two clamps. In order to prevent the clamp from accidentally loosening and causing the air cylinder to fall off, it is necessary to add an air cylinder fall-off protection device.

[0030] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0031] like Figure 1 and Figure 2 As shown, it is a structural schematic diagram of embodiment 1 of the utility model, which provides a wind cylinder fall-off protection structure, which is installed on the welding frame 100 of the wind cylinder module, and includes two support assemblies arranged at the axial ends of the wind cylinder 200. The support assembly includes a support beam 1 located below the wind cylinder 200 and two column groups arranged at the two ends of the length direction of the support beam 1. The lower end of the column group is fixedly connected to the support beam 1 and the upper end is fixedly connected to the welding frame 100.

[0032] In order to improve the stability of the structure, two torsion-resistant plates 2 are connected between the two support components, and the two torsion-resistant plates 2 are respectively arranged at both ends of the support beam 1 in the length direction.

[0033] The middle part of the torsion plate 2 is X-shaped, that is, four through-holes are provided on the torsion plate 2, and there are X-shaped reinforcing ribs between the four through-holes, so that the strength of the torsion plate 2 can be ensured and the weight can be reduced at the same time. In order to improve the strength of the torsion plate 2, the first bending edges 2-1 are respectively provided at the upper and lower ends of the torsion plate 2.

[0034] The support beam 1 is a U-shaped bending part, that is, a U-shaped groove 1-1 is provided at the upper end of the support beam 1, and the U-shaped groove 1-1 is adapted to the protrusion on the outer wall of the air cylinder 200. When the air cylinder 200 falls, the protrusion is located in the U-shaped groove 1-1, which can reduce the axial movement of the air cylinder 200. The protrusion here refers to the welded square boss around the drainage hole below the air cylinder 200, and the clamp straps on both sides of the air cylinder 200. At the same time, the width of the support beam 1 is consistent with the main beam of the welding frame, and the support beam 1 is connected to the welding frame through the column group to ensure the stability of the structure.

[0035] The column group includes two columns 3 arranged on both sides of the support beam 1 in the width direction. Preferably, the columns 3 are made of sheet metal, and the columns 3 are fixedly connected to the support beam 1 and the welding frame 100 by bolts.

[0036] In order to improve the structural strength of the column 3 , a second bending edge 3 - 1 is provided on the side of the column 3 away from the support beam 1 . The second bending edge 3 - 1 also facilitates the connection between the column 3 and the anti-torsion plate 2 .

[0037] To facilitate the installation of the air cylinder 200, an arc-shaped avoidance groove 3-2 is provided on one side of the column 3 facing the air cylinder 200, and the arc-shaped avoidance groove 3-2 is adapted to the outer diameter of the air cylinder 200.

[0038] An installation plate 300 extending in the vertical direction is fixed on the welding frame 100. To facilitate the connection between the support beam 1 and the welding frame 100, one of the columns 3 located on the outside is set to a parallelogram structure and its height is less than the distance between the support beam 1 and the welding frame 100. The upper end of the column 3 is fixed on the installation plate 300 and is fixedly connected to the welding frame 100 through the installation plate 300.

[0039] To play a role in weight reduction, weight reduction through grooves are provided on the column 3 and the support beam 1.

[0040] As Figure 3 shown, it is a schematic structural diagram of Embodiment 2 of the present invention. Others are the same as Embodiment 1. The differences are as follows: To prevent foreign objects on the track from hitting the ball valve below the air cylinder 200 during driving, two anti-collision beams 4 are connected between the two support components. The two anti-collision beams 4 are arranged at both ends in the length direction of the support beam 1. At the same time, setting the anti-collision beams 4 can improve the strength of the protection structure.

[0041] In summary, the protection structure can play a comprehensive role in preventing detachment, avoid the air cylinder from tilting and falling on one side, and improve the safety performance of the vehicle.

[0042] The above examples are only for illustrating the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be covered within the protection scope of the present invention.
