The specific embodiment
Warship of the present utility model comprises drop-gear box 10 with canoe folding and unfolding winch, and drop-gear box 10 inside are provided with three grades of axles 83, secondary axle 82, primary axis 81 and main shaft 80 from top to bottom.Drop-gear box 10 1 sides are provided with HM Hydraulic Motor 7, and HM Hydraulic Motor 7 links to each other with primary axis 81.Primary axis is provided with gear 61 and gear 63.HM Hydraulic Motor 7 drives the gear 61 of primary axis 81, and gear 61 drives the gear of establishing on the main shaft 80 62, and gear 62 drives main shaft 80 and rotates.Main shaft 80 drives the reel 12 that is arranged with rope, realizes furling of rope, drives canoe and rises.Reel 12 sides are provided with roller device 4, are compressed the rope of winding on the reel 12 by roller device 4.
Secondary axle 82 is provided with clutch equipment 5 in the drop-gear box 10, and clutch equipment 5 comprises son, female friction lining, and sub-friction lining and secondary axle 82 link, and female friction lining connects with first gear 64 of clutch equipment 5 one sides.First gear 64 is meshed with gear 63, and first gear 64 does not rotate with secondary axle 82.Also be provided with clutch plunger cover 51, belleville spring 53 and second gear 66 on the secondary axle 82 successively.The hydraulic rotary joint 52 of clutch equipment 5 stretches out outside the drop-gear box 10, connects exterior hydraulic efficiency pressure system.Gear 65 set on second gear 66 on the secondary axle 82 and the three grades of axles 83 is meshed.
Usually under the state, (do not comprise the situation that hydraulic efficiency pressure system breaks down) when hydraulic efficiency pressure system is not worked, sub, female friction lining compresses under belleville spring 53 pressure effects mutually, and promptly clutch equipment 5 is in normally off.Sub, female friction lining phase mutual friction this moment, first gear 64 links together with the friction force of secondary axle 82 by son, female friction lining.Drive the secondary axle by first gear 64, drive second gear 66 again and rotate.Second gear 66 drives the gear 65 that is provided with on three grades of axles 83, and three grades of axles 83 are rotated.Thereby make limit speed for braking condition device 9 brakes of establishing on three grades of axles 83.
When clutch equipment 5 will be opened, hydraulic efficiency pressure system was started working, and clutch plunger cover 51 moves right under the hydraulic oil effect, does not have pressure between son, the female friction lining at this moment, and sub, female friction lining separates, and promptly secondary axle 82 connects with 64 disengagements of first gear.Limit speed for braking condition device 9 is not worked at this moment, and HM Hydraulic Motor 7 drives reels 12 and rotates, and realizes the normal folding and unfolding work of canoe.
When clutch equipment 5 wanted closed, under the effect of belleville spring 53, the hydraulic oil that the clutch plunger cover is 51 li was discharged from, and clutch plunger cover 51 compresses son, female friction lining again simultaneously, made 9 brakes of limit speed for braking condition device, and canoe is stopped.
Limit speed for braking condition device 9 is connected with three grades of axles 83.Limit speed for braking condition device 9 is provided with weight 1, and weight 1 links to each other with limit speed for braking condition device 9 in-to-in weight sleeves 96.Weight sleeve 96 connects cam body 95, and cam body 95 connects brake hoop 94, and brake hoop 94 belows are provided with brake band 93, brake band 93 and brake disc 92 closed contacts.
When weight 1 put down, weight sleeve 96 drove cam body 95, and cam body 95 drives brake hoop 94, and brake hoop 94 compresses brake band 93, plays the effect of brake.When lifting weight 1, brake band 93 is loosened, and limit speed for braking condition device 9 lost efficacy.
In the time of need putting ship, hydraulic efficiency pressure system is not worked, and promptly clutch equipment 5 is in closure state.Hold weight 1, brake band 93 unclamps with brake disc 92, and brake disc 92 is not subjected to friction drag, and jolly boat descends by self gravitation, and the whole box body inner gear rotates under reel 12 drives, and jolly boat begins to descend.Convex with axle on the brake disc 92 of limit speed for braking condition device 9, speed limit piece 91 is enclosed within on the protruding axle of brake disc 92, with restraint of labour ship lowering velocity.
Stop when putting down weight 1 tight (brake disc 92 stops operating, and the axle that connects with it stops operating, and transmits step by step reel 12 is stopped operating), jolly boat stops to descend.By putting down or hold weight 1, the state of transferring of Control work ship (descend or stop descend) at any time.
Manual unit 11 comprises a ratchet 3, and the shell of limit speed for braking condition device 9 is provided with the ratchet 2 that matches with ratchet 3.When needs manually played ship, manual unit 11 and three grades of axles 83 linked together, and ratchet 3 can only just change under the effect of ratchet 2 and can not reverse.
When hydraulic efficiency pressure system can not be worked, adopt the ship mode of manually receiving.Be hydraulic efficiency pressure system when breaking down, clutch equipment 5 auto-closings, limit speed for braking condition device 9 is started working, and installs manual unit 11 this moment earlier, and with ratchet 2 and ratchet 3 engagements, holds weight 1 then.Because three grades of axles are linked together with manual unit 11 for 83 this moments, manual unit 11 can't reverse because of the effect of ratchet 2, therefore holds 1, three grade of axle 83 of weight this moment and also can't reverse.The crank of establishing on the forward rotation manual unit 11 makes canoe begin to rise, and finishes the work of manual receipts ship.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
