Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, but not as limitation of the present invention:
Embodiment one, a kind of folding ramp peculiar to vessel, including 1, door frame 4 of a fixed base plate, many group truss groups, fixed base plate 1 is fixed with hull position, door frame 4 is hinged with fixed base plate 1 by pivot pin, described door frame 4 is U-shaped window frame structure, U-shaped window frame structure includes montant A and the cross bar of bottom on both sides, the rear of door frame 4 both sides montant A is provided with reinforcement strut, it is provided with, on the left and right end face on montant A top, door frame 4 both sides, the waist typed through hole being vertically arranged, being provided with spacing wheels 5 on waist typed through hole, spacing wheels 5 can slide in waist typed through hole；The inner side of door frame 4 both sides montant A is provided with expansion oil cylinder 2, and the base launching oil cylinder 2 is all hinged by the cross bar bottom pivot pin and door frame 4, and the piston rod of expansion oil cylinder 2 is all hinged with spacing wheels 5 pivot pin of the same side；The lower front of door frame 4 is provided with fixed base plate 1, and fixed base plate 1 top is provided with the base of pitching oil cylinder 3, and the piston rod of pitching oil cylinder 3 is hinged with the front end face of montant A bottom, door frame 4 both sides；Being provided with truss group in the U-shaped peripheral frame of door frame 4, often group truss group is formed by the truss rod 12 being symmetrically arranged and a truss frame 11, and truss frame 11 is U-shape structure, and U-shape structure includes the montant B on both sides and the lower shaft 7 of bottom；Truss frame 11 is respectively positioned on the inner side of two truss rods 12 in left and right, truss rod 12 is all by hinged in the middle part of bearing pin and the montant B of truss frame 11 the same side, the truss frame 11 montant B top of the first truss group is all hinged with the spacing wheels 5 of the same side, bottom the truss frame 11 montant B of the first truss group, all truss frame 11 montant B with the second truss group are hinged, bottom the truss rod 12 of the first truss group, all door frame 4 montant A with the same side are hinged, and truss rod 12 top of the first truss group is all hinged with truss rod 12 top of the second truss group；It is the most hinged with one end that second truss group many groups truss group backward is truss rod 12, and truss frame 11 is the most hinged with one end；It is provided with universal wheel 13 bottom last group truss group in many group truss groups；Truss frame 11 is internal is equipped with limiting plate 8 and shifting stage 6, and shifting stage 6 one end is hinged with lower shaft 7, and other end both sides arrange directive wheel 9, and both sides arrange the inner side of directive wheel 9 and are equipped with hook plate 10；During folding, limiting plate 8 is respectively positioned on the front of hook plate 10；Described many groups truss group is by launching oil cylinder 2 action, it is achieved the course of action launching and shrinking；When truss group is launched, composition organizes parallelogram sturcutre more, and shifting stage 6 is when the effect of limiting plate 8 and directive wheel 9 is transferred to setting position, and hook plate 10 snaps on the lower shaft 7 of previous group truss group；After truss group is all launched, truss group and many group shifting stages 6 form stable truss structure, can bear deadweight and person weight；After described many groups truss group is launched, pitching oil cylinder 3, fixed base plate 1 and door frame 4 form quadric chain, and pitching oil cylinder 3 can control door frame 4 and many group truss groups swing up and down adjustment angle.
As Figure 1 and Figure 4, pitching oil cylinder 3, fixed base plate 1 and door frame 4 form quadric chain, and when pitching oil cylinder 3 action, door frame 4 realizes swinging up and down；Expansion oil cylinder 2, door frame 4, spacing wheels 5 form quadric chain and realize the slip on door frame 4 of the spacing wheels 5, and the quadric chain of door frame 4, spacing wheels 5, truss frame 11, truss rod 12 composition achieves expansion and the contractive action of truss group.
Such as Fig. 2, shown in 5, follow-up truss group is hinged to the first corresponding truss rod of truss group, and composition organizes parallelogram sturcutre, along with expansion and the contraction of the first truss group more, it is achieved launches while organizing truss groups more and shrinks.
As it is shown on figure 3, often group truss frame 11 bottom is provided with lower shaft 7, the internal both sides of truss frame 11 are provided with limiting plate 8 and shifting stage 6, and shifting stage 6 one end is hinged with lower shaft 7, and other end both sides arrange directive wheel 9, and end is provided with hook plate 10.
Such as Fig. 3, shown in 5, when truss group is launched, shifting stage 6 hook plate 10 when the effect of limiting plate 8 and directive wheel 9 is transferred to setting position snaps on the lower shaft 7 of previous group truss group, and truss frame 11, truss rod 12, shifting stage 6, hook plate 10 are formed and stablize truss structure.After folding ramp launches to put down, when the universal wheel 13 of springboard end is bearing on harbour, many group truss groups and shifting stage 6 form stable truss structure, in order to bear deadweight and person weight.
When being embodied as, the folding ramp peculiar to vessel of the present invention is not owing to using fixing type beam structure, but uses many group truss groups to be formed and organize parallelogram sturcutre more, forms the springboard between hull and harbour, it is simple to the upper and lower shipping agency of personnel is walked when truss group is launched；After truss group is packed up, taking up room relatively small, power uses hydraulic oil cylinder driving, and human users is convenient, can reach easy and simple to handle, take up room little effect.
Obviously, above-described embodiment is only for clearly demonstrating example of the present invention, and not restriction to embodiment.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here without also cannot all of embodiment be given exhaustive, and the obvious change thus amplified out or variation still in protection scope of the present invention among.
