Description

Technical Field

[0001] This utility model belongs to the field of railway equipment technology, specifically relating to a portable crossbar for railway use. Background Technology

[0002] When performing maintenance work on railway locomotives, it is often necessary to cross maintenance trenches, or to work directly above the trenches when inspecting the locomotive from the front. This necessitates the use of ramps to provide passageways or standing platforms for maintenance work. Common ramps are made of a single piece of steel, which is large and heavy, making them inconvenient to move or use.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this utility model is to provide a portable crossrail for railways to solve the problems of existing crossrails being too bulky and inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable crossbar for railway use includes a main pedal and at least one auxiliary pedal, the auxiliary pedal being movably connected to the end of the main pedal.

[0007] The auxiliary pedal is equipped with a caster at the end away from the main pedal;

[0008] The auxiliary pedal can be folded toward one side of the main pedal.

[0009] Preferably, the auxiliary pedal is connected to the main pedal via a hinge.

[0010] Preferably, the angle between the auxiliary pedal and the main pedal is adjustable between 0 and 180°.

[0011] Preferably, the hinge is provided with a spring pin, which is used to lock the hinge.

[0012] Preferably, the angle between the auxiliary pedal and the main pedal can be fixed at 90° and / or 180°.

[0013] Preferably, each end of the main pedal is provided with an auxiliary pedal.

[0014] Preferably, the length of the main pedal does not exceed the rail gauge.

[0015] Preferably, the length of the main pedal is 1430 mm or less.

[0016] Beneficial effects:

[0017] (1) The cross-track ramp provided by this utility model adopts a folding structure, which allows the auxiliary pedal to be folded towards the main pedal, thereby reducing the size of the ramp before and after use, making it easy to carry and transport. During use, it can be easily unfolded, allowing people to cross a relatively wide area, making it highly practical.

[0018] (2) The cross-track ramp can be locked by spring pin after the auxiliary pedal is folded to be perpendicular to the main pedal, so that the main pedal and the auxiliary pedal maintain a 90° angle. Then, the caster at the end of the auxiliary pedal can be used as a trolley, making it more functional than the traditional ramp. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" and "second" may explicitly or implicitly include one or more features.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection or a movable connection, a detachable connection or a non-detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection or a connection that can communicate with each other; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements, an indirect connection, or an interaction between two elements.

[0030] The present invention will now be described in detail with reference to the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0031] This utility model addresses the problems of large size and inconvenient transportation of traditional crossrail crossings by providing a portable crossrail crossing for railways, such as... Figures 1-3 As shown, the ramp includes a main pedal 1 and at least one auxiliary pedal 2. For example, an auxiliary pedal 2 can be provided at one end of the main pedal 1, or an auxiliary pedal 2 can be provided at each end of the main pedal 1. The auxiliary pedal 2 is movably connected to the end of the main pedal 1, so that the auxiliary pedal 2 can be folded toward one side surface of the main pedal 1 to reduce the overall length of the ramp, save space, and make it easy to transport.

[0032] The auxiliary pedal 2 and the main pedal 1 can be detachably connected, such as by snap-fit ​​or pin-fit, so that the auxiliary pedal 2 can be stacked with the main pedal 1 after being detached. Alternatively, they can be rotatably connected, such as by a pivot, so that the auxiliary pedal 2 can rotate along the pivot until it is in contact with the surface of the main pedal 1. The angle between the auxiliary pedal 2 and the main pedal 1 is adjustable between 0 and 180°.

[0033] In a preferred embodiment of this utility model, the auxiliary pedal 2 is connected to the main pedal 1 via a hinge 3, and the hinge 3 can be locked at a specific angle, thereby restricting the rotation of the auxiliary pedal 2 relative to the main pedal 1, so that the main pedal 1 and the auxiliary pedal 2 are fixed at the included angle after rotation, and form an arch bridge shape, a door shape, or a state in which the main pedal 1 and the auxiliary pedal 2 are completely in contact.

[0034] Furthermore, the hinge 3 is provided with a spring pin 5, which is used to lock the hinge 3. When the spring pin 5 is locked, the angle between the auxiliary pedal 2 and the main pedal 1 can be fixed at a specific angle, thereby keeping the main pedal 1 and the auxiliary pedal 2 in a specific shape.

[0035] For example, after locking hinge 3 by spring pin 5, the angle between auxiliary pedal 2 and main pedal 1 can be fixed at 90° or 180°, so that main pedal 1 and auxiliary pedal 2 form a... Figure 4 The shape shown is either a gate shape, or a shape in which the main pedal 1 and the auxiliary pedal 2 are completely stacked.

[0036] Furthermore, a caster 4 is provided at the end of the auxiliary pedal 2 away from the main pedal 1, and the main pedal 1 and the auxiliary pedal 2 form a shape as follows: Figure 4 The U-shaped structure shown can be locked with spring pin 5, allowing the platform to be used as a trolley or a mobile workbench, making it more versatile.

[0037] In this invention, the length of the main pedal 1 does not exceed the gauge of the railway rail 6, for example, the length is 1430mm or less of the standard gauge of the railway rail 6, so that the hinge 3 at the connection between the main pedal 1 and the auxiliary pedal 2 can be placed between the tracks of the railway rail 6, which plays a certain limiting role.

[0038] In a preferred embodiment of this utility model, the distance between the outer sides of the hinge 3 connecting the main pedal 1 and the auxiliary pedal 2 is 1430mm. After the auxiliary pedal 2 is unfolded 180 degrees, the hinge 3 is locked. The auxiliary pedal 2 is flush with the upper surface of the main pedal 1 and can be placed on the rail 6. The rail 6 is clamped by the outer side of the hinge 3, which restricts the sliding of the treadmill.

[0039] With the above setup, when the ramp is needed, the folded auxiliary pedal 2 is opened outward to 180°, and then the hinge 3 is locked with the spring pin 5, so that it can be laid across the maintenance trench for workers to pass through, or used as a maintenance platform.

[0040] When it needs to be used as a mobile workbench, rotate the auxiliary pedal 2 to a position where it forms a 90° angle with the main pedal 1, and then lock the hinge 3 by the spring pin 5. Then, the caster 4 can be used to push it to move. At this time, the main pedal 1 can be used as a workbench to place maintenance tools and other items.

[0041] In summary:

[0042] This utility model adopts a folding structure, allowing the auxiliary pedal 2 to fold towards the main pedal 1, thus making the cross-track platform easy to carry and transport. Moreover, it can be easily unfolded during use, allowing people to cross areas with relatively large widths. In addition, after the auxiliary pedal 2 is folded to be perpendicular to the main pedal 1, the hinge 3 is locked by a spring pin 5, keeping the main pedal 1 and auxiliary pedal 2 at a 90° angle. It is also equipped with casters 4, which allows it to be used as a trolley. Compared with traditional cross-track platforms, it has richer functions and can solve the problems of existing cross-track platforms being too large and inconvenient to carry.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
