The specific embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～5, the technical scheme that the utility model adopts is: a carriage part is fixed arm 1 for fixed type.Two triangle brackets of a part, one of them triangle bracket is comprised of oil cylinder I 6, movable arm I 4 and deck by axle III 5, axle IV 8 and axle I 2; The another one triangle bracket is comprised of hydraulic actuating cylinder II 13, movable arm II 15 and deck by axle VII 14, axle V 11 and axle VI 12; Utilize pull bar 9, movable arm I 4, movable arm II 15 and deck to form four-bar linkage by axle IV 8, axle II 3, axle VI 12 and axle VII 14, driven by oil cylinder I 6 and oil cylinder II 13.
Carriage is installed on the suitable position on the deck in the cabin, the hydraulic rams realization of holding up and falling and by two the fluid-control one-way lock being housed of carriage, because this holder keel block is equipped with the fluid-control one-way lock, can guarantee carriage in the situation that rated load with internal burden, is stably held canoe.
(1) carriage basic structure
Such as the structural representation of Fig. 2, hydraulic-driven holder keel block shown in Figure 4, fixed arm 1 is connected with the deck on the one hand, increases stability and the rigidity of structure of carriage; Connect movable arm I 4 by axle I 2 on the other hand, connect movable arm II 15 by axle VIII 16.The axis of the axis of the axis of axle II 3, axle IV 8 and axle I 2 in one plane, its axis I 2 and axle II 3 installation sites are coaxial; The axis of the axis of the axis of axle V 11, axle VI 12 and axle VII 14 in one plane, its axis V 11, axle VI 12 installation sites are coaxial.
Two triangle brackets, axle I 2 are installed on the fixed arm 1, and axle IV 8 is installed on the movable arm I, and axle II 3 is installed on the base I 7, and 7 fixed installations of base I above deck; One of them triangle bracket is comprised of oil cylinder I 6, movable arm I 4 and deck by axle I 2, axle IV 8 and axle III 5.Axle VIII 16 is installed on the fixed arm 1, and axle VII 14 is installed on the movable arm II 15, and axle V 11 is installed on the base II 10, and 10 fixed installations of base II above deck; The another one triangle bracket is comprised of hydraulic actuating cylinder II 13, movable arm II 15 and deck by axle VII 3, axle V 11 and axle VI.Utilize pull bar 9, movable arm I 4, movable arm II 15 and deck to form four-bar linkage by axle IV 8, axle II 3, axle VI 12 and axle VII 14.Axle III 5 is conllinear with axle II 3 space parallels but not, and axle V 11 and axle VI 12 also be space parallel but conllinear not, so can be driven by oil cylinder I 6 and oil cylinder II 13, finish the action of holding up and fell.
