Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described:
As Figure 1-3, in the utility model preferred embodiment, transport outrigger comprises three joints and divides bridge, be respectively bridge 1, bridge 24 and bridge 35, as shown in Figure 3, when transporting each frame contraction of outrigger and putting in place, bridge one is positioned at outermost layer, bridge two is arranged in bridge one, and bridge three is arranged in bridge two, forms the structure that three layers of support body stacks.During use, be rotationally connected by bridge one and hull.
In hull, be provided with portal frame 51, cable one end of drawing of fixing each bridge is fixedly connected with portal frame, and the other end connects corresponding bridge.The lower end of portal frame 51 and hull are rotationally connected by axle 52, and portal frame actuating device 53 can drive portal frame to rotate 54 around axle, portal frame can be made to be in and be vertically also fixed as dynamic on a corresponding position with the position tilted.
Preferred portal frame actuating device 53 is cylinder or hydraulic actuating cylinder, gas (hydraulic pressure) cylinder is positioned at ship, cylinder is obliquely installed, the cylinder body of cylinder is fixed in hull, piston rod is fixedly connected with portal frame, and like this, when piston rod stretches out, portal frame can be in vertical position, when piston rod is regained, portal frame can be tilted to hull.
Portal frame actuating device 53 also can be jack, or fork driven by stepper motors.
Each bridge is stretched by bridge retractable driving device.The bridge retractable driving device of the structure as Fig. 4-5 can be adopted, realize the synchronization telescope of each bridge.Concrete structure is as follows:
As Figure 4-Figure 6, the both sides, front end of bridge one are provided with bridge one fixed pulley 9, at the corner location place of bridge one, quarter block is set respectively, about being positioned at bridge one front end, each one is front hook pulley 14, about being positioned at bridge one rear end, each one is bridge two quarter block 15, the both sides, rear end of bridge 24 be respectively arranged with bridge two advance after movable pulley 10, bridge two advances one end of steel rope 2 to connect the winding drum 1 of winch 1, the other end connects bridge one fixed pulley 9 of homonymy, the bridge two connecting homonymy again advances rear movable pulley 10, connect the front hook pulley 14 of homonymy again, quarter block 14 through homonymy is diverted to the front hook pulley 14 being positioned at opposite side, the bridge two connecting opposite side again advances rear movable pulley 10, connect bridge one fixed pulley 9 of opposite side again, finally be fixedly connected with the winding drum two 13 coaxial with winding drum 1.When winch starts to rotate, shrink bridge two and advance steel rope 2, bridge two is pushed into, and forward end moves, and reaches outside bridge one.
In order to realize bridge two and the indentation of bridge San Tong method and stretch out, with fixed length steel rope 8 connecting bridge one, bridge two and bridge three.Be specially, the head end of fixed length steel rope 8 is fixedly connected on the side of bridge three anchor shaft 7, the bridge two then connecting homonymy successively advances bridge two quarter block 15 of bridge two quarter block 15 of front movable pulley 6, homonymy, opposite side, the bridge two of opposite side advances front movable pulley 6, is finally fixedly connected on the opposite side of bridge three anchor shaft 7.
Fixed length steel rope 8 and above-mentioned pulley is adopted to coordinate, when fixed length steel rope 8 received by the reel of winch, bridge two stretches out, after the bridge two arranged due to fixed length steel rope and bridge two front end advances front movable pulley 6 to be connected, be fixedly connected with again bridge three anchor shaft 7 that bridge three rear end is arranged, so reach outside bridge one along with bridge two, bridge three also synchronously reaches outside bridge two.When bridge two does retraction campaign under actuating device drives, winch release bridge two advances steel rope 2, and bridge two moves in bridge one, and bridge three synchronously moves in bridge two.
Certainly, fixed length steel rope 8 and bridge two advance steel rope 2 can be isometric two respectively.Such as, when bridge two advances steel rope 2 to be two, connect a winding drum by every bar steel rope, bridge one fixed pulley 9 of the homonymy that is then linked in sequence respectively, bridge two advance rear movable pulley 10, and bridge two advances the tail end of steel rope 2 to be fixedly connected on the front end homonymy of bridge one.
When fixed length steel rope 8 is isometric two, one end of every bar fixed length steel rope 8 is fixedly connected with bridge three anchor shaft 7 of side, then the bridge two connecting homonymy successively advances front movable pulley 6, is finally fixedly connected on the homonymy rear end of bridge one.
Adopt a fixed length steel rope 8 and a bridge two to advance steel rope 2 to be connected pulley and bridge one, bridge two and bridge three, bridge two and bridge three two ends can be kept to be synchronized with the movement better.
Certainly, transport outrigger can be made up of the above support body of three joints, advance on the basis of the method for steel rope connecting bridge one and bridge two at the above-mentioned bridge two of employing, with reference to the method with fixed length steel cable connecting bridge one, bridge two and bridge three, bridge one, bridge three and frame four can be linked together, realize bridge three and frame four synchronous, thus it is synchronous to realize bridge two, bridge three and frame four.By said structure, can arrange point frame that more piece is synchronized with the movement, each point of support body is all synchronized with the movement with bridge two.
Preferably, bridge two advances front movable pulley 6 to be running block, and bridge one fixed pulley 9 is the certain assembly pulley of bridge, and bridge two advances rear movable pulley 10 to be running block, and bridge two quarter block 15 is corner sliding wheels.
The mode that gear and toothed track also can be adopted to be combined with motor is to realize the flexible of bridge two and bridge three, such as, bridge one arranges the toothed track of stretching for bridge two, bridge two arranges gear, turned by motor-driven gear and rotate in toothed track, thus bridge two is stretched out or is retracted in bridge one, in bridge two, also toothed track is set equally, bridge three arranges gear, is rotated by motor driven gear.In this bridge retractable driving device, also should inhibiting device be set, limits the position that inner side bridge stretches out and retracts.
Be provided with winch two in board, when bridge two and bridge three are all recovered to after in bridge one, the cable that draws of winch two pulls bridge one, bridge two and bridge three by the pulley that portal frame is arranged, each bridge is made to draw close on portal frame, when needs stretch out each bridge, cable is drawn in winch release, and Jiang Geqiao sets level, and bridge two and bridge two-way gap bridge retractable driving device are stretched out.
When work is complete or ship navigation needs to regain bridge, first by bridge retractable driving device, the bridge being positioned at upper strata is taken in the bridge being positioned at lower floor, in the bridge one that each bridge is all entered into as main bridge, by bridge pull unit by vertical for each bridge pull-up, draw close with the portal frame erect, drive portal frame tilted to hull by portal frame actuating device, with hold together bridge that door frame draws close also along with tilted to hull, after tilting to certain angle, fix portal frame by portal frame actuating device, thus telescopic bridge is recovered in hull.
Adopt the peculiar to vessel convertible retractile bridge of the utility model structure, retractile bridge overall shrinkage to as in the bridge one of main bridge, and tilts to be fixed in stem, so it is little to take up room together with portal frame, superelevation can not encounter bridge in the process of moving, not take stem space simultaneously.
