Abstract
Description
Technical Field
[0001] The utility model relates to a vehicle unloading platform, in particular to a roll-on / roll-off vehicle unloading platform. Background Art
[0002] Railway car couplers are typically installed in the same orientation, so simply rotating the cars aligns the coupler centers, achieving a proper connection. However, to accurately align and connect the couplers between the unloading platform and the car, simply flipping the coupler is not feasible. This is because the irregularities of the coupler's top surface and the smoothness of its bottom surface do not match, and a simple flip can make securing difficult. During the train's pickup and delivery process, the challenge is to securely fasten the coupler to the unloading platform while also ensuring its safety and reliability under severe impact. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a roll-on / roll-off car unloading platform with reasonable design and convenient use, which can ensure the stability and withstand various forces during train operation, thereby ensuring the stability and reliability of the coupler.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A roll-on / roll-off car unloading platform is characterized in that it includes a docking platform, a main unloading platform and a ramp connected in sequence; a coupler connected to a railway carriage is provided in front of the docking platform, a slot extending backward is provided on the front side of the docking platform, a buffer device connected to the coupler is provided in the slot, and eaves panels for filling the gap between the railway carriage and the docking platform are provided on the docking platforms on both sides of the slot; the docking platform, ramp and main unloading platform are all concrete platforms, steel mesh is placed in the ramp and the main unloading platform, and a number of vertical bars for strengthening the main body of the platform are installed in the docking platform, and the vertical bars are arranged in an array; upper main bars and lower main bars extending to the rear of the docking platform are installed in the eaves board, and the lower main bars are connected to the upper main bars by stirrups.
[0006] The technical problem to be solved by the present invention can also be achieved through the following technical solutions, a coupler anti-collision plate is provided at the front of the slot, the coupler anti-collision plate is arranged perpendicular to the unloading direction, the coupler anti-collision plate is fixed to the docking platform through the front plate beam, a rear baffle is provided at the rear of the slot for preventing the railway carriage from colliding with the docking platform, the rear baffle is arranged along the unloading direction, the rear baffle is fixed to the docking platform through the rear plate beam, the front of the buffer device is fixed to the front of the slot through the front plate beam, and the rear of the buffer device is fixed to the rear of the slot through the rear plate beam.
[0007] The technical problem to be solved by the present invention can also be achieved through the following technical solution: an angle steel edge guard is provided on the front side of the eaves board to protect the eaves board, so as to prevent the eaves board from being damaged.
[0008] The technical problem to be solved by the present invention can also be achieved through the following technical solution: a rotating seat for installing the coupler is installed at the front end of the coupler buffer device. By rotating the coupler 180° and then welding it to the platform, we effectively solve the fixing difficulties and mismatching problems existing in the traditional connection method, and improve the stability and reliability of the connection.
[0009] The technical problem to be solved by the present invention can also be achieved through the following technical solution: an insertion hole for inserting a lamp pole is provided on the docking platform to facilitate the installation of the lamp pole.
[0010] Compared with the prior art, the present invention has the following technical effects:
[0011] First, through independent reinforcement, namely the distribution of vertical reinforcement within the docking platform, the placement of steel mesh within the ramp and main unloading platform, and the installation of upper and lower main reinforcement and stirrups within the cantilever plate, we ensured that the platform could withstand the various forces exerted during train pickup and delivery. During the design process, we conducted detailed train impact calculations to ensure that the unloading platform could maintain its structural integrity and stability under severe impact.
[0012] Secondly, the coupler striker, front plate beam, rear plate, and rear plate beam provide reliable support and protection for the coupler, while also acting as a buffer for vehicle coupling. These structural designs not only consider the platform's own load-bearing capacity but also fully account for various situations that may occur during connection with the train, ensuring safety and stability during the connection process.
