Description

Technical Field

[0001] This utility model relates to the field of rail passenger car door frame guardrail technology, and in particular to a rail passenger car door frame guardrail device. Background Technology

[0002] In the maintenance and repair of rail passenger vehicles, the disassembly of door panels is a common work step. Due to the weight of the door panels and the fact that they often involve electrical and mechanical components, the disassembly and repair process carries certain safety risks. Especially during door panel disassembly, operators may be exposed to potential hazards such as falling door panels, loss of control of mechanical parts, or sudden external forces. Therefore, effective protective measures are needed to ensure the safety of operators during door panel disassembly and repair. However, existing rail passenger vehicle door frame guardrail devices have shortcomings in terms of installation efficiency, structural stability, ease of operation, and safety. Therefore, developing an efficient, stable, easy-to-operate, and safe door frame guardrail device is an urgent problem to be solved. Summary of the Invention

[0003] In view of this, the present invention provides a rail passenger car door frame guardrail device to solve the problems existing in the rail passenger car door frame guardrail device in terms of installation efficiency, structural stability, ease of operation and safety.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A railcar door frame guardrail device includes a connecting bolt, through which a first guardrail frame and a second guardrail frame are rotatably connected. The first guardrail frame and the second guardrail frame are complementary structures. The top and bottom ends of the first guardrail frame and the second guardrail frame are equipped with U-shaped supports for support. The connecting bolt is located in the middle of the first guardrail frame and the second guardrail frame.

[0006] Furthermore, holes are provided on the first and second guardrail frames and located at the edge of the U-shaped support.

[0007] Compared with the prior art, this utility model has the following advantages:

[0008] The railcar door frame guardrail device described in this utility model is simple to operate and can provide efficient, stable, easy-to-operate and safe door frame guardrail protection when the railcar door panels are disassembled and repaired. Attached Figure Description

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "back," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] This embodiment relates to a rail passenger car door frame guardrail device, which can solve the problems existing in rail passenger car door frame guardrail devices in terms of installation efficiency, structural stability, ease of operation and safety.

[0019] Based on the above design concept, an exemplary structure of the rail passenger car door frame guardrail device in this embodiment is as follows: Figure 1-3 As shown, it mainly includes connecting bolts 1, through which a first guardrail frame 2 and a second guardrail frame 3 are rotatably connected. The first guardrail frame 2 and the second guardrail frame 3 are complementary structures. U-shaped supports 4 are installed at the top and bottom of both the first guardrail frame 2 and the second guardrail frame 3 to provide support. It can be understood that in specific installations, rubber padding is added to the U-shaped supports 4 to protect the vehicle body and enhance the stability of the support. The connecting bolts 1 are located in the middle of the first guardrail frame 2 and the second guardrail frame 3. Holes 5 are provided on the first guardrail frame 2 and the second guardrail frame 3, located at the edge of the U-shaped supports 4, to facilitate the installation of protective netting.

[0020] In this embodiment, when the railcar door frame guardrail device is in use, the first guardrail frame 2 and the second guardrail frame 3 are rotated to form a fork-shaped structure, the U-shaped support 4 is clamped onto the railcar door frame, and a protective net is installed on the holes 5 on the first guardrail frame 2 and the second guardrail frame 3.

[0021] The railcar door frame guardrail device using the above implementation scheme effectively protects the safety of railcar door panels during disassembly and maintenance, while also being highly efficient in installation, structurally stable, easy to operate, and highly safe.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
