TECHNICAL FIELD

[0001] The present application relates to the technical field of roll-on / roll-off transportation equipment, and particularly relates to a portable transportation roll-on / roll-off platform. BACKGROUND

[0002] With the promotion of global economic integration, the equipment manufacturing industry gradually develops in the direction of heavy and large-scale, which puts forward higher requirements for cargo transportation, especially the loading and unloading of ships of major goods. As an efficient loading and unloading method, roll-on technology has been widely used in the field of port logistics and has become an important part of the modern port logistics system. Roll-on technology not only significantly improves the loading and unloading efficiency, but also effectively reduces the dependence on terminal facilities, providing a new solution for port logistics.

[0003] In actual operation, in order to realize the roll-on loading and unloading of major goods, a large shore crane or a water floating crane operation method is usually used. However, these methods are limited by various factors, such as the height of the wharf, the channel conditions, the tidal changes, etc. In order to solve these problems, the commonly used means currently include the use of fixed roll-on platforms, mobile cranes and temporarily built transition structures. Although the fixed roll-on platform has good stability, it has poor adaptability and cannot meet the needs of wharfs of different heights; the mobile crane has high flexibility, but has high cost and complex operation; the temporarily built transition structure can adjust the height, but has a long construction period and low safety.

[0004] The above conventional means generally have the problem of insufficient adaptability when facing wharfs of different heights. Especially in the case of large differences between the height of the wharf and the height of the ship's freeboard, it is difficult to realize the efficient roll-on loading and unloading of major goods, which seriously affects the progress of the project. CONTENT OF THE INVENTION

[0005] In order to improve the loading and unloading efficiency of major goods at the wharf, the present application provides a portable transportation roll-on / roll-off platform.

[0008] By adopting the above technical scheme, the support platform is supported by the load bearing buttress which can be lifted and adjusted, can adapt to wharfs and ship decks of different heights, and effectively solves the problem of large height difference between wharf and ship freeboard.

[0009] Optionally, the lifting and adjusting assembly includes a threaded sleeve fixed on the heightening buttress and a servo motor for driving the heightening buttress to rotate, the threaded sleeve is threadedly connected with the base buttress cylinder, and the heightening buttress is rotatably arranged at the bottom of the support platform through a bearing, the servo motor is arranged at the top of the support platform, and an output shaft of the servo motor is rotatably arranged through the support platform and coaxially connected with the heightening buttress.

[0010] By adopting the above technical scheme, the servo motor drives the heightening buttress to rotate, and the lifting and adjusting of the heightening buttress is realized by the thread connection between the threaded sleeve and the base buttress cylinder. Since the thread adjustment is stepless adjustment, the height of the support platform can be accurately controlled. This design not only flexibly adapts to wharfs and ship decks of different heights, but also improves the stability and safety of roll on roll off operation, simplifies the operation process, and improves the loading and unloading efficiency.

[0011] Optionally, the inner bottom of the base buttress cylinder is provided with a limit switch electrically connected to the servo motor, and when the bottom end of the heightening buttress descends to contact the limit switch, the servo motor stops running.

[0012] By adopting the above technical scheme, when the heightening buttress descends to contact the limit switch, the servo motor stops running in time, effectively reduces the possibility of damage of the servo motor due to excessive running, and improves the safety and reliability of the load bearing buttress during height adjustment.

[0013] Optionally, the support platform is provided with a protective cover corresponding to each servo motor.

[0014] By adopting the above technical scheme, the protective cover can effectively prevent the roll-on transport vehicle from colliding with the servo motor when adjusting the arrangement position on the support platform, reduce the possibility of damage to the servo motor due to accidental impact, and reduce the interference of external factors on the servo motor, thereby improving the service life and working reliability of the servo motor.
