[0001] This utility model relates to the field of railway maintenance equipment technology, specifically to a driver's cab for a rail milling vehicle. Background Technology
[0002] The existing driver's cab design of rail milling vehicles has several shortcomings. First, traditional driver's cab structures typically place the entire cab above the chassis, resulting in limited longitudinal space and restricted driver movement. Furthermore, the high door height makes getting in and out inconvenient. Second, some designs only have a door on one side of the cab. If one door malfunctions or is damaged, the driver cannot enter or exit from the other side, posing a safety hazard. In addition, the connection between the cab's frame structure and the chassis in existing designs is complex, making it difficult to guarantee the cab's strength and limiting the overall lightweight design.
[0003] Therefore, optimizing the structural design of the cockpit, expanding longitudinal space, reducing door height, improving the convenience of getting in and out of the vehicle, while enhancing the strength of the cockpit and achieving lightweighting are urgent technical problems to be solved.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a driver's cab for a rail milling vehicle, including a connecting body 1 and a cab body 2. The connecting body 1 is welded to the rear of the cab body 2, and the lower side of the connecting body 1 is higher than the lower side of the cab body 2. A chassis 3 is mounted on the lower side of the connecting body 1, and a recessed chassis 4 is welded to the front end of the chassis 3. The recessed chassis 4 is located below the cab body 2. The connecting body 1 and the cab body 2 are fixedly mounted on the chassis 3 and the recessed chassis 4 by screws and other fasteners. An axle 5 is mounted on the lower part of the chassis 3, and wheels 6 are mounted on both sides of the axle 5. Doors 11 are rotatably mounted on both sides of the cab body 2 via hinges, and the lower side of the doors 11 is flush with the lower side of the chassis 3.
[0017] Specifically, the connecting body 1 is bolted to the rear of the cab 2. The lower side of the connecting body 1 is higher than the lower side of the cab 2, thus providing more longitudinal space for the cab 2. A chassis 3 is mounted on the lower side of the connecting body 1. The chassis 3 is a welded steel frame used to support the connecting body 1 and to tow the rear milling equipment. The steel frame structure of the sunken chassis 4 can be less strong than that of the chassis 3, only providing rigid protection for supporting the cab 2 and extending to the front of the cab 2, which facilitates the weight reduction of the entire driver's cab.
[0018] In this embodiment, the sunken chassis 4 includes a column 41 vertically welded to the front end of the chassis 3. The upper end of the column 41 is welded to the chassis 4 and the lower end is welded to a support frame 42. A front protective frame 43 is welded to the front end of the support frame 42 and the front protective frame 43 is located above the support frame 42.
[0019] In this embodiment, front reinforcing ribs 44 are welded to the upper ends of both sides of the front protective frame 43. The lower ends of the front reinforcing ribs 44 are welded and fixedly connected to the side of the support frame 42. A bent reinforcing rib 45 is welded to the upper end of the column 41. The lower end of the bent reinforcing rib 45 is welded and fixedly connected to the side of the support frame 42. A bent reinforcing rib 46 is welded to the lower end of the column 41. The upper end of the bent reinforcing rib 46 is welded and fixedly connected to the side of the chassis 3.
[0020] In this embodiment, wheels 6 are installed on both sides of the axle 5. The wheels 6 are connected to the axle 5 through wheel hubs and are used to support the driver's cab and realize the movement function.
[0021] In this embodiment, doors 11 are installed on both sides of the driver's cab 2. The lower side of each door 11 is flush with the lower side of the chassis 3, thereby reducing the height of the door 11 and facilitating driver entry and exit.
