The utility model can also comprise:
1, principal arm one end is installed the first synchronizer gear, and forearm one end is installed the second synchronizer gear, the first synchronizer gear and the engagement of the second synchronizer gear.
2, also comprise the 3rd hydraulic actuating cylinder, sub-arm, the 3rd hydraulic actuating cylinder is installed on the forearm, and sub-arm is installed in the contiguous block, and the 3rd hydraulic actuating cylinder connexon arm also is with the relative contiguous block of mover arm to make fore and aft motion.
Advantage of the present utility model is: the two joint mechanical arms that the utility model proposes and a joint telescoping mechanism, length of boom can be determined as required, the overlength needs of arm can be realized, convenient folding simultaneously, transportation, storage space are dwindled greatly, improve the safety of lash ship.
Description of drawings
Fig. 1 is expansion front view of the present utility model;
Fig. 2 is folding schematic diagram of the present utility model;
Fig. 3 is sub-arm schematic diagram of the present utility model.
The specific embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, the technical scheme that the utility model adopts is: at first form a parallel four-bar linkage by pedestal 1, principal arm 4, principal arm pull bar 8 and joint 13, this four connecting rod is driven by oil cylinder I and cylinder rod I; Form the another one parallel four-bar linkage by forearm 21, front arm brace 22, contiguous block 27 and joint 13 again, driven by oil cylinder II 17 and cylinder rod II 18; Form the synchromesh gear system by the gear I 11 that is installed in principal arm 4 and the gear II 12 that is installed in forearm simultaneously; And at contiguous block 27 the sub-arm 29 that can stretch is installed, sub-arm 29 is driven by oil cylinder III 23 and cylinder rod III 24; At the connecting bore 30 that sub-arm 29 bodies are processed mechanisms such as putting the pendulum cover is installed.
The stretching, extension of arm and folding realize by three hydraulic rams that balance cock is housed respectively, simultaneously synchronizer gear engagement make principal arm 4 realize relative to the joint that around the axle VI 13 constant speed are outwards rotated or constant speed is inwardly rotated around axle V 10 and forearm 21.In draw off gear when normal operation, only used the arm folded part, when stormy waves comparison Da Yi the lifesaving canoe occurs bumps with the hull sidewall, sub-arm 29 parts stretched out the distance of increase canoe and lash ship.
Pedestal 1 is initiating terminal, can be installed on certain desired location on the deck in ship structure by bolt, and principal arm 4 is installed on the pedestal 1 by the axle II, and oil cylinder I 5 and principal arm pull bar 14 are by on axle I 2 mounting bases; Simultaneously, principal arm 4 other ends are installed on the joint 13 by axle V 10, principal arm pull bar 14 also is installed on the joint 13 by axle IV 9, makes pedestal 1, principal arm 4, principal arm pull bar 8 and joint 13 form parallel four-bar linkage by axle I 2, axle II 3, axle IV 9 and axle V 10; Oil cylinder I 5 is installed on the pedestal by axle I 2, and the oil cylinder I bar 6 of the other end is installed on the principal arm 4 by axle III 7, when oil cylinder I bar 6 relative oil cylinder I 5 are made fore and aft motion, drives principal arm 4 around 3 rotations of axle II.
One end of forearm 21 is installed on the joint 13 by axle VI 14, and the other end is installed on the contiguous block 27 by axle XI 25; One end of front arm brace 22 is installed on the joint 13 by axle VII 15, and the other end is installed on the contiguous block 27 by axle XII 26; Axle VI 14, axle VII 15, axle XI 25 and axle XII 26 make joint 13, forearm 21, front arm brace 22 and contiguous block 27 also form flat quadrangle; Oil cylinder II 17 is installed on the forearm 21 by axle VIII 16, and oil cylinder II bar 18 is installed on the forearm 21 by axle IX 19, when oil cylinder II bar 18 relative hydraulic actuating cylinder II 17 are made relative fore and aft motion, drives forearm 21 and rotates around axle VI 14.
The folding of arm realized by hydraulic actuating cylinder I 5 and the hydraulic actuating cylinder II 17 that balance cock is housed respectively, but under fluid control, be difficult to realize that principal arm 4 realizes relative to the joint that around the axle VI 13 constant speed are outwards rotated or constant speed is inwardly rotated around axle V 10 and forearm 21, at principal arm 4 gear I 11 is installed, at forearm 21 gear II 12 is installed, gear I 11 and gear II 12 form gear motion, realize relative to joint 13 variable speeds outwards rotates or variable speed when inwardly rotating around axle V 10 and forearm 21 around axle VI 14 at principal arm 4, force principal arm 4 to realize relative to the joint that around axle VI 14 13 realize that constant speed are outside and rotate or constant speed is inwardly rotated around axle V 10 and forearm 21 at mechanical mechanism.
When lifesaving canoe and hull sidewall occur and bump in stormy waves comparison Da Yi, increase the distance of canoe and lash ship, at contiguous block 27 the dilaton arm 29 that only has one degree of freedom is installed, hydraulic actuating cylinder III 23 is installed on the forearm 21 by axle X 20, hydraulic stem III 24 is installed on the sub-arm 29 by axle 28, when hydraulic stem III 24 relative hydraulic actuating cylinder III 23 were made fore and aft motion, sub-arm 29 relative contiguous blocks 27 were made fore and aft motion.
