Description

Technical Field

[0001] The utility model relates to the technical field of rail locomotives, in particular to an anti-twisting device for a brake pipe of a railway locomotive. Background Art

[0002] When existing rail vehicles are reconnected, the angle plug door needs to be opened to achieve air reconnection of the brake pipe (including train pipe and main air pipe) between the vehicles. When the vehicles are uncoupled, the angle plug door needs to be closed to separate the two vehicles. Since the angle plug door is used frequently, the angle plug door needs to be opened for air reconnection between vehicles and closed for uncoupling. Long-term opening and closing of the angle plug door will cause the brake pipe joint to loosen, causing the brake pipe to twist and even cause the brake pipe to deform. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a railway locomotive brake pipe anti-twist device to prevent the brake pipe joint from loosening when the angle plug is frequently operated. The specific technical solution is as follows:

[0004] A railway locomotive brake pipe anti-twist device comprises an anti-twist plate I and an anti-twist plate II. The cross sections of the anti-twist plate I and the anti-twist plate II are both L-shaped. The anti-twist plate I and the anti-twist plate II are connected by screws. The anti-twist plate I and the anti-twist plate II are stepped after being spliced. The bolt holes on the fitting edge of the anti-twist plate I are long holes. A notch for installing a corner plug is opened on the non-fitting edge of the anti-twist plate I. A fixing seat is provided on the non-fitting edge of the anti-twist plate II.

[0005] Furthermore, rib plates are provided at the corners of the anti-twist plate I and the anti-twist plate II.

[0006] Furthermore, the fixing seat is of guide rail type, and the fixing seat and the anti-twist plate II are fixedly connected.

[0007] The beneficial effects of the utility model are:

[0008] 1. The angle plug door is installed by this device, which avoids the brake pipe joint being loosened when the angle plug door is frequently operated, causing the brake pipe to be twisted or deformed.

[0009] 2. The hole connecting the anti-twist plate I and the anti-twist plate II is a long hole. The distance between the anti-twist plate I and the anti-twist plate II can be adjusted according to the extended length of the brake pipe at the vehicle end. At the same time, the fixing seat is a guide rail type, which can be installed at a designated position according to installation requirements, and has a wider applicability.

[0017] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0018] The utility model provides the following specific implementation schemes, and it should be noted that the "fitting edge" is the edge where the anti-twist plate contacts with another anti-twist plate, and the "non-fitting edge" is the edge where the anti-twist plate does not contact with another anti-twist plate:

[0019] like Figure 1-2As shown, the utility model provides an anti-twist device for a brake pipe of a railway locomotive, comprising an anti-twist plate Ⅰ1 and an anti-twist plate Ⅱ2, the cross-sections of the anti-twist plate Ⅰ1 and the anti-twist plate Ⅱ2 are both L-shaped, the anti-twist plate Ⅰ1 and the anti-twist plate Ⅱ2 are connected by screws, the anti-twist plate Ⅰ1 and the anti-twist plate Ⅱ2 are stepped after being spliced, the bolt holes on the fitting edge of the anti-twist plate Ⅰ1 are long holes 4, a notch for installing a corner plug 5 is provided on the non-fitting edge of the anti-twist plate Ⅰ1, and a fixing seat 3 is provided on the non-fitting edge of the anti-twist plate Ⅱ2.

[0020] Specifically, Figure 3 As shown, the angle between the axis of the opening direction of the notch on the anti-twist plate Ⅰ1 and the corner edge of the anti-twist plate Ⅰ1 can be 0°, 30°, 45° or 60°.

[0021] Specifically, ribs are provided at the corners of the anti-twist plate Ⅰ1 and the anti-twist plate Ⅱ2 to enhance the stability of the structure.

[0022] Specifically, Figure 4 As shown, the fixing seat 3 is of guide rail type, and the fixing seat 3 and the anti-twist plate II 2 are fixedly connected. In this embodiment, the fixing seat 3 is made of a hollow square tube with a groove on one side, and the grooved side is in contact with the anti-twist plate I 1 .

[0023] In the present invention, the bolt holes on the mating edge of the anti-twist plate Ⅰ1 and the bolt holes on the mating edge of the anti-twist plate Ⅱ2 can both be elongated holes 4, or one of them can be an elongated hole 4 and the other can be a round hole.

[0024] like Figure 5 As shown, when in use, the angle plug door 5 is installed at the notch on the anti-twist plate Ⅰ1 by screws, and the guide rail type fixing seat 3 is installed on the locomotive.

[0025] By installing the angle plug door 5 through the present device, the brake pipe joint is prevented from loosening when the angle plug door 5 is frequently operated, which causes the brake pipe to twist or deform. The hole connecting the anti-twist plate I1 and the anti-twist plate II2 is a long hole 4. The distance between the anti-twist plate I1 and the anti-twist plate II2 can be adjusted according to the extended length of the brake pipe at the vehicle end.
