It is dynamic, it is further driven to the first connecting rod 28 hinged with second hydraulic cylinder 27 and the hinged second connecting rod 30 of the second hydraulic push rod 29
It is rotated, finally drives universal wheel rotation, so that the decentralization completely of entire universal wheel mechanism 2；Then the reversed oil transportation of hydraulic pump makes
Plunger rod 4 is pushed back into plunger piston fluid pressure cylinder 3, so that the slow decentralization of entire keel block ontology 1 touches ground up to universal wheel wheel body 32,
State is as shown in Figure 3；Then tractor, will be whole by catching on the guiding piece 6 on 1 front end face of keel block ontology containing circular hole with car puller hook
A device is drawn to unmanned boat collection site, is then repeated the above steps, and is first put down plunger rod 4 and is propped up whole device, then receives
Universal wheel mechanism 2 is returned, state after withdrawal makes keel block body bottom portion land, starts to recycle as shown in fig. 6, withdrawing plunger rod 4 again
Unmanned boat.
2. transport storage unmanned boat scene
When needing to transport unmanned boat to somewhere or storage to somewhere, before tractor is by catching on keel block ontology 1 with car puller hook
Containing the boss of circular hole on end face, whole device is drawn to specified storage place, then hydraulic-driven support foot mechanism passes through simultaneously
Hydraulic pump oil transportation pushes respective plunger rod 4 that it is allowed to transfer, until three stabilizer blades 5 are all with ground face contact and by entire keel block ontology
1 props up so that universal wheel wheel body 32 is liftoff, and the then oil transportation simultaneously of the hydraulic pump in universal wheel mechanism 2 makes the first hydraulic push rod 24
It pushes back into first hydraulic cylinder 23, drives and rotated with the hinged rocking bar 25 of the first hydraulic push rod 24 around second cross beam 26, further band
The dynamic first connecting rod 28 hinged with second hydraulic cylinder 27, the second connecting rod 30 hinged with the second hydraulic push rod 29 are rotated, most
Universal wheel rotation is driven afterwards, so that entire universal wheel mechanism 2 is retracted in the rectangular recess 7 of 1 bottom of keel block ontology；Then hydraulic
Drive support foot mechanism by the reversed oil transportation of hydraulic pump, so that plunger rod 4 is pushed back into plunger piston fluid pressure cylinder 3, so that whole device is slow
Decline, until keel block ontology 1 bottom and ground face contact, finally remove tractor car puller hook, complete unmanned boat transport and
Storage.
Therefore, in conjunction with above-mentioned construction and the course of work it can be found that removable unmanned boat keel block device of the present invention
Structure novel is skillfully constructed, and is used not only for disposing unmanned boat in various places such as lash ship, warehouses, but also can be quick
Mobile, transport unmanned boat, the process for improving unmanned boat working efficiency, simplifying unmanned boat recycling, transport, have it is convenient to use,
The advantages that structure is simple, safe and reliable, using effect are good.
