The force acting on the upper guide rails 1 in roll-on roll-off operation is converted from the wharf ground 6 to the wharf pile foundation 7 by the bottom guide rails 2 and the load-bearing partitions 5, so that the whole weight load of the port machinery equipment is transmitted to the wharf pile foundation 7 above through the double-layered track, without the need to modify the original pile foundation wharf to meet the roll-on roll-off operation of the port machinery equipment on the existing pile foundation wharf, which is safe and reliable and can well meet the strength requirement of the wharf for large equipment roll-on roll-off operation, and provides an effective track structure for roll-on roll-off operation.

[0030] Further, in the embodiments, each upper guide rail 1 and each bottom guide rail 2 can be assembled and fixed by a plurality of guide rail units. By using the structure of end-to-end assembly, the size of the roll-on roll-off operation site can be assembled according to the size of the roll-on roll-off operation site, which can effectively reduce the occupation area of the wharf site and improve the utilization rate of the wharf.

[0031] In one of the embodiments, the jacking assembly can be arranged to comprise: a connecting lug 3 fixed with the upper guide rail 1 for supporting the upper guide rail during rail extraction, and a jacking device 4 arranged below the connecting lug 3 for providing a source of rail extraction support force.

[0032] The connecting lug 3 and the jacking device 4 are used to jack up the upper guide rail 1, so that the force acting on the upper guide rail 1 is transferred from the bottom guide rail 2 to the jacking device 4, and the upper guide rail 1 is in a suspended state by jacking of the jacking device 4 during travel and / or turning and / or rail extraction of the roll-on roll-off operation vehicle, so as to perform rail extraction operation on other upper guide rails and / or bottom guide rails, thereby improving the utilization rate of the wharf. The jacking device 4 can be a hydraulic device such as a jack.

[0033] Further, the connecting lug 3 comprises a jacking plate connected with the upper guide rail 1. The jacking plate can be fixed with the upper guide rail 1 by welding. Figure 4 and 5 As shown, the connecting lug 3 can further comprise a reinforcing connecting plate arranged between the upper guide rail 1 and the jacking plate for stabilizing the jacking plate. One end of the reinforcing connecting plate is fixedly connected with the upper guide rail 1, and the other end is fixedly connected with the jacking plate by welding.

[0034] It should be noted that the number of reinforcing plates can be set to 1 or 2 or 3, and the specific number is not limited in the embodiment, which can be set according to the actual guide rail bearing.

[0035] The connecting lug seat 3 of the present application can use waste steel, that is, the jacking plate and / or the reinforcing plate can be assembled and fixed into an integrated connecting lug seat using waste steel plate, which not only can jack up the upper guide rail 1, but also can achieve the effect of recycling waste steel resources and saving costs. The bearing partition plate can also use steel plate, and the size is cut according to the wharf pile foundation, such as 1m*1m, etc., so as to support the bottom rail 2 to separate from the wharf ground through the bearing partition plate 5, so as to achieve the effect that the force of the rail is transmitted to the wharf pile foundation 7.

[0036] Further, based on the above track structure, the embodiment of the present application also provides a wharf roll-on / roll-off transportation system, which comprises a roll-on / roll-off vehicle for heavy equipment roll-on / roll-off operation and a track arranged on the wharf pile foundation for the transportation of the roll-on / roll-off vehicle, and the track adopts the structure of the above-mentioned wharf double-layered cross-shaped roll-on / roll-off track. The roll-on / roll-off vehicle walks on the wharf double-layered cross-shaped track, so that the weight of the roll-on / roll-off vehicle is transmitted to the upper guide rail 1, the upper guide rail 1 transmits the force to the bottom guide rail 2, and the bottom guide rail 2 transmits the force to the bearing partition plate 5, and then the bearing partition plate 5 transmits the force to the wharf pile foundation 7, so that the wharf pile foundation bears the load of large port machinery equipment, which can well meet the requirement of the pile foundation wharf bearing capacity for large port machinery equipment roll-on / roll-off operation.

[0037] Further, based on the above wharf roll-on / roll-off transportation system, the embodiment of the present application also provides a wharf roll-on / roll-off operation method, which specifically comprises the following contents:

[0038] Before the roll-on / roll-off operation, the wharf double-layered cross-shaped roll-on / roll-off track is built on the corresponding position of the wharf according to the roll-on / roll-off ship environment, so as to form a complete and continuous roll-on / roll-off operation channel, so that the overall force of the wharf in the heavy equipment roll-on / roll-off operation is converted from the wharf ground to the wharf pile foundation;

[0039] During the roll-on / roll-off operation, the roll-on / roll-off operation vehicle performs the roll-on / roll-off operation of the heavy equipment between the ship and the wharf through the wharf double-layered cross-shaped roll-on / roll-off track, and the jacking assembly supports the upper guide rail 1 where the vehicle is located when the roll-on / roll-off operation vehicle walks and / or turns and / or falls off the track, so as to perform the rail extraction operation on the other upper guide rail 1 and / or the bottom guide rail 2.
