Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to restriction of the present utility model:

Embodiment one, folding ramp peculiar to vessel, including 1, door frame 4 of a fixed base plate, many group truss groups, fixing seat Plate 1 is fixed with hull position, and door frame 4 is hinged with fixed base plate 1 by pivot pin, and described door frame 4 is U-shaped window frame structure, U-shaped encloses Mount structure includes that montant A and the cross bar of bottom on both sides, the rear of door frame 4 both sides montant A are provided with reinforcement strut, door frame 4 It is provided with, on the left and right end face on montant A top, both sides, the waist typed through hole being vertically arranged, waist typed through hole is provided with position-limited wheel Group 5, 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, launches oil The base of cylinder 2 is all hinged by the cross bar bottom pivot pin and door frame 4, launch the piston rod of oil cylinder 2 all with the position-limited wheel of the same side Organize 5 pivot pins hinged；The lower front of door frame 4 is provided with fixed base plate 1, and fixed base plate 1 top is provided with the end of pitching oil cylinder 3 Seat, the piston rod of pitching oil cylinder 3 is hinged with the front end face of montant A bottom, door frame 4 both sides；It is provided with purlin in the U-shaped peripheral frame of door frame 4 Frame group, 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-shaped knot Structure, 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 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 Portion 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 with the truss of the second truss group Montant B is hinged for frame 11, and bottom the truss rod 12 of the first truss group, all door frame 4 montant A with the same side are hinged, the first truss group Truss rod 12 top is all hinged with truss rod 12 top of the second truss group；Second truss group many groups truss group backward is purlin Hack lever 12 is the most hinged with one end, and truss frame 11 is the most hinged with one end；Bottom last group truss group in many group truss groups It is provided with universal wheel 13；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, 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；Work as purlin When frame group is launched, composition organizes parallelogram sturcutre more, and shifting stage 6 is transferred to setting in the effect of limiting plate 8 and directive wheel 9 During position, hook plate 10 snaps on the lower shaft 7 of previous group truss group；After truss group is all launched, truss group and the activity of many groups are jumped Plate 6 forms 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 Degree.

As Figure 1 and Figure 4, pitching oil cylinder 3, fixed base plate 1 and door frame 4 form quadric chain, when pitching oil cylinder 3 moves When making, door frame 4 realizes swinging up and down；Launch oil cylinder 2, door frame 4, spacing wheels 5 form quadric chain and realize spacing wheels 5 and exist Slip on door frame 4, the quadric chain of door frame 4, spacing wheels 5, truss frame 11, truss rod 12 composition achieves truss group Launch and contractive action.

Such as Fig. 2, shown in 5, follow-up truss group is hinged to the first corresponding truss rod of truss group, composition many groups parallelogram knot Structure, along with expansion and the contraction of the first truss group, it is achieved launches while many group truss groups 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 live Dynamic springboard 6, 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 is transferred to setting in the effect of limiting plate 8 and directive wheel 9 When location is put, hook plate 10 snaps on the lower shaft 7 of previous group truss group, truss frame 11, truss rod 12, shifting stage 6, hook plate 10 shape Become to stablize truss structure.After folding ramp launches to put down, when the universal wheel 13 of springboard end is bearing on harbour, organize purlin more Frame group and shifting stage 6 form stable truss structure, in order to bear deadweight and person weight.

When being embodied as, folding ramp peculiar to vessel of the present utility model is not owing to using fixing type beam structure, but adopts Formed by many group truss groups and organize parallelogram sturcutre more, form the springboard between hull and harbour when truss group is launched, it is simple to people Member's shipping agency up and down is walked；After truss group is packed up, taking up room relatively small, power uses hydraulic oil cylinder driving, and human users is convenient, can reach To easy and simple to handle, take up room little effect.

Obviously, above-described embodiment is only for clearly demonstrating this utility model example, and not to embodiment party The restriction of formula.For those of ordinary skill in the field, can also be made other on the basis of the above description different The change of form or variation, here without also cannot all of embodiment be given exhaustive, and thus amplified out aobvious and The change that is clear to or variation still in protection domain of the present utility model among.
