Description

Technical Field

[0001] The invention belongs to the technical field of ship berthing, and in particular relates to a ship berthing structure with variable height. Background Art

[0002] Currently, conventional docking ramp designs are all hinged hydraulic flip ramps, which can be slightly adjusted in angle according to the height of the truck's cargo box and connected with it. This is no problem for fixed vehicle models (carriage height).

[0003] However, when encountering vehicles of different heights, the lower end of the door of the vehicle with a lower height will hit the ramp plate, making the operation more cumbersome: that is, before opening the door, the ramp needs to be flipped to 90 degrees, and then the door can be opened (such as Figure 5 As shown in the figure, this operating environment is difficult, the procedures are cumbersome, and the safety hazards are relatively large. Therefore, a new type of ramp is needed that can adapt to the height of the carriages of various models without affecting the operation. Summary of the invention

[0008] Furthermore, a ramp support column is fixed on the upper end surface of the support column base, and the ramp support column is arranged parallel to the vertical side wall of the structural pit. The horizontal plane where the upper end surface of the ramp support column is located is below the horizontal plane where the upper end surface of the berthing deck is located.

[0009] Furthermore, when the second sheet is in a horizontal state, the lower end surface of the second sheet abuts against the upper end surface of the ramp support column, and the side of the second sheet away from the berthing deck extends to the side of the ramp support column away from the structural pit.

[0010] Furthermore, when the second sheet is rotated into the notch of the first sheet, the end surface of the first sheet away from the berthing deck and the end surface of the second sheet away from the berthing deck are located in the same vertical plane.

[0011] Furthermore, the berthing ramp also includes a ramp toe end for bridging the cargo container chassis, and an upper end surface on one side of the ramp toe end in the length direction is rotatably connected to an upper end surface of the second sheet body on a side away from the berthing deck.

[0012] Furthermore, the toe end of the ramp rotates 180 degrees around the connection point between the toe end of the ramp and the second sheet body, and the longitudinal section of the toe end of the ramp is an upwardly curved arch.

[0013] Furthermore, the number of the ramp toe ends is one or more, and the total length of the ramp toe ends is greater than the length of the second sheet body and less than or equal to the length of the first sheet body.

[0014] Furthermore, the length of the notch is greater than the length of the first sheet, and the first sheet and the notch are arranged coaxially.

[0015] Furthermore, the hydraulic drive device is a hydraulic cylinder, and the connection point between the hydraulic drive device and the first sheet body is located directly below the side of the first sheet body recess close to the berthing deck.

[0016] The ship variable height mooring structure of the present invention has a first sheet connected to a second sheet by a hinge, which can ensure that the second sheet is in the notch of the first sheet at any working angle, and the initial position state of the mooring ramp is that the side of the first sheet away from the mooring deck abuts against the inner lower part of the ramp support column, the second sheet is in a horizontal state, abuts against the upper end surface of the ramp support column, and the ramp toe is entirely located on the upper end surface of the second sheet; when mooring, the truck door is opened in the above initial state, and the truck door is located between the left and right sides of the first sheet and the left and right sides of the notch; then, the hydraulic drive device is turned on to lift the first sheet, and a suitable overlapping height is adjusted to overlap the ramp toe with the cargo box chassis.
