Description

Technical Field

[0001] The utility model relates to the field of anti-slip devices, in particular to an anti-slip device for railway locomotives. Background Art

[0002] With the continuous development of railways in recent years, the transport capacity of various railway locomotives, transport flatbed cars, rail cars, etc. has gradually increased. After the vehicle stops on the line, it relies on the vehicle's own braking system to maintain braking. After a long period of parking or the powered locomotive and coupled vehicles are separated, when a single or multiple vehicles are parked on the line, in addition to relying on their own braking, external measures are also needed to prevent the vehicle from sliding forwards or backwards.

[0003] For example, a patent for a railway locomotive anti-slip device (Announcement No.: CN207000473U) includes a carrier plate, one end of which extends forward to form a transition plate, a transition head fixed to the end of the transition plate away from the carrier plate, a support plate fixed to the carrier plate, and a clamping plate mounted on the support plate. The top surface of the clamping plate cooperates with the upper surface of the transition plate to form an angle structure. The top surface of the clamping plate presses against the wheel. The angle formed by the cooperation of the transition plate and the clamping plate is used to lock the wheel to prevent slipping, and the angle is usually an obtuse angle. The utility model is used to prevent stationary railway vehicles from slipping when moving forward and backward. The transition head is used to introduce one end of the transition plate into the gap between the wheel and the top surface of the rail, so that the clamping plate is close to the vehicle wheelset. When the parked vehicle slips, the bottom surface of the wheelset presses on the transition plate, preventing the carrier plate from sliding on the rail surface. The clamping plate supports the vehicle wheelset, which can effectively prevent the parked vehicle from slipping. The anti-slip device is simple to manufacture, low in cost, and convenient and quick to use.

[0004] The aforementioned patent utilizes a carrier plate and a clamping plate to effectively prevent parked vehicles from rolling away and provides ease of use. However, in daily use, the clamping plate is secured to the carrier plate via a support plate, limiting the size of locomotive wheels the device can accommodate. Furthermore, the smooth outer surfaces of the clamping plate and carrier plate make it difficult to support locomotive wheels of varying sizes and materials on the clamping plate, thus narrowing the device's applicability. Therefore, it is essential to invent a locomotive anti-rolling device to address these issues. Utility Model Content
