Description

Technical Field

[0001] The utility model relates to a railway flat car reinforcement technology, in particular to a non-destructive reinforcement wheel type and crawler type vehicle device and a railway flat car. Background Art

[0002] The bundling and reinforcement of wheeled and tracked vehicles is a crucial aspect of rail transport and a key factor influencing and restricting rapid loading and unloading. Currently, standard 70t-capacity flatcars are often used for rail transport of wheeled and tracked vehicles.

[0003] According to the structural characteristics of flat cars, the loading and securing schemes for various types of goods such as wheeled and tracked vehicles and equipment on railway flat cars and shared flat cars in relevant regulations mostly use saw nails, wooden nails, and wire ropes for reinforcement. The disadvantages of this method are as follows:

[0004] (1) During the nailing and removal process, the saw nails can easily cause damage to the vehicle floor, resulting in higher vehicle use costs.

[0005] (2) The scrap rate of the triangular blocks, square timber, iron wire and other equipment used is high, resulting in a great waste of resources.

[0006] (3) The actual reinforcement process consumes a lot of manpower, is labor-intensive, and is cumbersome and inefficient.

[0007] In order to solve the problem of easy damage to vehicle floors, many solutions have been tried, but they all have their own problems.

[0008] Chinese patent CN117141531A discloses a shielding and reinforcement device for railway flat cars, comprising a fixed seat, a guide rod, a transverse connecting seat and a fixed block; the guide rod is arranged along the length direction of the chassis; there are at least two fixed seats, at least one of which is fixedly connected to the guide rod, and the other fixed seats are slidably connected to the guide rod; at the same time, the fixed seat is arranged to be detachably connected to the column plug; the length direction of the transverse connecting seat is substantially perpendicular to the length direction of the guide rod, and it is slidably connected to the guide rod; the fixed block is arranged on the transverse connecting seat, and the fixed block has at least one shielding surface, which is arranged to abut against the wheels of the vehicles loaded on the railway flat car, and is used to limit and reinforce the loaded vehicles. The shielding and reinforcement device does not require the use of saw nails or round steel nails to be nailed to the floor, and will not cause damage to the floor, but relies on the column plugs on the side for positioning and fixing, which has certain limitations.

[0009] Chinese patent CN117382687A discloses a reinforcement device for railway flat cars and a railway flat car. The reinforcement device includes a fastening unit, a connecting unit, a wheel chock, and a fixing portion. The connecting unit and the wheel chock are detachably mounted on the flat car, and the wheel chock is mounted on the connecting unit. The fastening unit is mounted on the side of the flat car body and is used to fix the wheel chock to the floor of the flat car through the connecting unit when the wheel chock is in a working state. The fixing portion is mounted on the side of the flat car body and is located below the fastening unit. It is used to fix the connecting unit and the wheel chock when the wheel chock is in a non-working state. This reinforcement device can not only replace the existing wooden shield reinforcement method, but also provide a more solid and reliable reinforcement method without damaging the floor. It can also be adjusted within a certain range along the longitudinal direction of the car body to adapt to the reinforcement of vehicles with different wheelbases. However, its cost is relatively high. Utility Model Content
