The present invention can also comprise:
1, the axis of the first described axle, the second axle, the 4th axle at grade.
2, the second described axle and the 3rd axle are not conllinear of space parallel.
Advantage of the present invention is: the present invention can reduce the setting height(from bottom) of draw off gear, increase the degree of automation of draw off gear, improve the rapidity of hull form, and can self-locking, have advantages of and reduce to hold in the palm the installing space of keel block and improve hull form device operation rapidity.

The specific embodiment
Below in conjunction with accompanying drawing, for example the present invention is described in more detail:
In conjunction with Fig. 1～5, the technical solution adopted in the present invention is: a bracket part for fixed type be fixed arm 1.Two triangle brackets of a part, one of them triangle bracket is comprised of oil cylinder I 6, movable arm I 4 and deck axle III 5, axle IV 8 and axle I 2; Another one triangle bracket is comprised of hydraulic actuating cylinder II 13, movable arm II 15 and deck axle VII 14, axle V 11 and axle VI 12; By axle IV 8, axle II 3, axle VI 12 and axle VII 14, utilize pull bar 9, movable arm I 4, movable arm II 15 and deck to form four-bar linkage, by oil cylinder I 6 and oil cylinder II 13, driven.
Bracket is installed on the suitable position on deck in cabin, the holding up and fell and realize by two hydraulic rams that fluid-control one-way lock is housed of bracket, because this holder keel block is equipped with fluid-control one-way lock, can guarantee that bracket with internal burden in the situation that, stably holds canoe in rated load.
(1) bracket basic structure
The structural representation of hydraulic-driven holder keel block as shown in Figure 2, Figure 4 shows, fixed arm 1 is connected with deck on the one hand, stability and the rigidity of structure of increase bracket; By axle I 2, connect movable arm I 4 on the other hand, by axle VIII 16, connect movable arm II 15.In one plane, its axis I 2 and axle II 3 installation sites are coaxial to the axis of the axis of the axis of axle II 3, axle IV 8 and axle I 2; In one plane, its axis V 11, axle VI 12 installation sites are coaxial to the axis of the axis of the axis of axle V 11, axle VI 12 and axle VII 14.
Two triangle brackets, axle I 2 is arranged on fixed arm 1, and axle IV 8 is arranged in movable arm I, and axle II 3 is arranged in base I 7, and 7 fixed installations of base I are above deck; One of them triangle bracket is comprised of oil cylinder I 6, movable arm I 4 and deck axle I 2, axle IV 8 and axle III 5.Axle VIII 16 is arranged on fixed arm 1, and axle VII 14 is arranged in movable arm II 15, and axle V 11 is arranged in base II 10, and 10 fixed installations of base II above deck; Another one triangle bracket is comprised of hydraulic actuating cylinder II 13, movable arm II 15 and deck axle VII 3, axle V 11 and axle VI.By axle IV 8, axle II 3, axle VI 12 and axle VII 14, utilize pull bar 9, movable arm I 4, movable arm II 15 and deck to form four-bar linkage.Axle III 5 is conllinear with axle II 3 space parallels but not, and axle V 11 and axle VI 12 be also space parallel but conllinear not, so can be driven by oil cylinder I 6 and oil cylinder II 13, complete the action of holding up and fell.
(2) holder keel block holds up/fell principle
In this holder keel block, movable arm I 4 can be rotated around axle I 2 and axle II 3, because oil cylinder I 6 is arranged in base I 7 by axle III 5, oil cylinder I bar is arranged in movable arm I by axle IV 8.In like manner, movable arm II 15 can be rotated around axle V 11 and axle VIII 16, and oil cylinder II 13 is arranged in base II 10 by axle V 11, and oil cylinder II bar is arranged in movable arm II by axle VII 14.Pull bar 9 is connected in movable arm I 4 and movable arm II 15 by axle IV 8 and axle VII 14, when movable arm I 4 is asynchronous with movable arm II 15, forces movable arm I 4 and movable arm II 15 synchronization actions.Oil cylinder I 6 and oil cylinder II 13 extended while shortening and driven movable arm I 4 and movable arm II 15 hold up and fell, pull bar 9 can synchronous movement arm I 4 and holding up with folding and unfolding of movable arm II 15 move; In addition two cylinder ports are all equipped with fluid-control one-way lock, and when not controlling oil pressure, movable arm can be unmovable due to load.
(3) the bracket process of falling
As Fig. 2, shown in 4, when oil cylinder I 6 and 13 shortening of oil cylinder II, movable arm I 4 clockwise rotates around axle 5 axle III, and movable arm II 15 clockwise rotates around axle VI 12, and two movable arms fell, and pull bar 9 reduces with movable arm simultaneously.
(4) folding process of mechanical arm
As Fig. 2, shown in 4, when oil cylinder I 6 and 13 elongation of oil cylinder II, movable arm I 4 rotates counterclockwise around axle 5 axle III, and movable arm II 15 rotates counterclockwise around axle VI 12, and two movable arms are holded up, and pull bar 9 raises with movable arm simultaneously.
