Description

A kind of Portable crane for Cargo Oil Pump deliver from vault
Technical field
The present invention relates to a kind of loop wheel machine, particularly a kind of Portable crane for Cargo Oil Pump deliver from vault.
Background technology
Cargo Oil Pump is the special equipment on oil carrier, its purposes be in the time of oil carrier landing pier by the respective line on ship by oilCargo Oil on ship is transported to year oily equipment or the oil depot harbour from cargo tank. Cargo Oil Pump is arranged on the bottom of ship's space, in dayIn normal maintenance and Renewal process, Cargo Oil Pump need to be transported to outside cabin, but due to the manhole cover diameter on the deck plane of boats and shipsToo small, for large ocean boats and ships, ship's space, from the excessive height on deck, therefore, is guarantee under-deck cargoes oil pump equipmentDeliver from vault, need to take measures smoothly, lifts by crane by boom hoisting.
For this reason, the Chinese invention patent " a kind of hanging clamp foreign material loop wheel machine " that the existing patent No. is ZL201410169957.9A kind of hanging clamp foreign material loop wheel machine of openly knowing clearly, comprising: pedestal, what be fixedly connected with pedestal hangs base, props up by revolutionHold and the rotating part that hangs base and be connected, the rotary reducer engaging with pivoting support, the strand that hoists being fixedly connected with rotating partCar, and be wound with hoist rope on the reel of described hoister winch, the free end of described hoist rope is along support barAxial direction walk around fixed pulley, hung fly block, its free-ended end is fixed on the fixed pin shaft of support bar, withAnd be connected with the input port of hoister winch, for hoister winch provides the air motor of power. But, by the foreign material of this inventionLoop wheel machine carries out deliver from vault lifting for Cargo Oil Pump, this foreign material loop wheel machine carrying inconvenience, meanwhile, operation while being installed above deckLoaded down with trivial details, in addition, this foreign material loop wheel machine is bulky, take up room large, and preservation not easy to store.
Summary of the invention
The technical problem to be solved in the present invention is the present situation for prior art, provides one to deposit conveniently, is convenient to move simultaneouslyMoving, the to install Portable crane for Cargo Oil Pump deliver from vault.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of Portable suspension for Cargo Oil Pump deliver from vaultMachine, comprises arm and suspension hook, and an end of described arm is provided with fixed pulley, and the rear side of described arm is provided with winch,Steel wire rope on winch is connected with suspension hook by after this fixed pulley, it is characterized in that: described arm disconnects in middle part,Form the first arm and the second arm, between described the first arm and described the second arm, be connected by flange, describedThe rear side of the first arm and the second arm is respectively arranged with supporting leg, on each supporting leg, is provided with pulley, described in close, hangsThe rear side of the other end of arm is provided with deflecting roller, is vertically provided with manhole cover seat ring detachable on the deck plane of boats and shipsFixing fixed support, this support bracket fastened top is provided with stator wheel, on the deck plane of boats and ships, has been horizontally disposed withWith detachably deflecting roller fixed mount that fix and that move for limiting described deflecting roller of described manhole cover seat ring.
As improvement, on the deck plane of boats and ships, be vertically provided with described manhole cover seat ring detachably fixing and with describedThe leading truck that fixed support is relative is respectively arranged with steel wire rope screw-button on described leading truck and described fixed support,On the boats and ships bilge relative with described manhole cover seat ring, be provided with shackle, between steel wire rope screw-button and shackle, be connected with and leadTo steel wire, between Cargo Oil Pump and guiding steel wire, be provided with guide plate. At loop wheel machine, Cargo Oil Pump is carried out in lifting process, byEasily shake in Cargo Oil Pump, lift by crane not steady, meanwhile, in the time that Cargo Oil Pump Access Opening is covered, because manhole cover diameter is too small,Easy and deck bumps, and deliver from vault is caused to certain difficulty, by leading truck, steel wire rope screw-button, shackle are setAnd guide plate, in Cargo Oil Pump lifting process, guide plate is along guiding steel wire upward sliding, and having limited Cargo Oil Pump may occurRock, solved because cabin cabin altitude is too high and caused Cargo Oil Pump to lift by crane difficult problem, ensured Cargo Oil Pump liftingStationarity in process and security.
Improve, described deflecting roller flushes with the other end of described arm again, when arm goes out under upright state, and deflecting rollerLand with the other end of arm simultaneously, jointly stressed, improve the stability of arm under in working order.
Improve again, be provided with the check lock lever removably connecting with described fixed support in the front side of described arm, when arm erectsAfter erecting, utilize check lock lever that arm is fixed and is connected with fixed support, prevented that arm is in lifting Cargo Oil Pump processMiddle tumbling.
Improve again, arrange and be detachably provided with rotating push-rod at the back of described arm, when arm is holded up to certain angle,By rotating push-rod, can manually arm be erected completely.
Improve again, between described fixed support and described deflecting roller fixed mount, be provided with stull, improve fixed support and turnTo the steadiness of wheel fixed mount.
Improve, the rear side of described the first arm is provided with directive wheel again, after this directive wheel of the steel wire penetrating on described winchAgain by fixed pulley, for the guide effect of steel wire rope.
Improve again, on described the first arm and described the second arm, be removably fixed with respectively handle.
Compared with prior art, owing to the invention has the advantages that: by arm is designed to separate form, reduced to hangThe volume of arm, and by fixed support and deflecting roller fixed mount by being removed and assembled into the pedestal of loop wheel machine, make the present inventionPortable crane be convenient to deposit, in addition, by the mode of pulley is set at the rear side of arm, facilitated the movement of arm,In the time that needs are installed loop wheel machine, first, fixed support and deflecting roller fixed mount are installed by the manhole cover seat ring place on deck planeIn place, then arm is moved near deflecting roller fixed mount, the deflecting roller on arm is arranged on deflecting roller fixed mount,Prevent the slippage of arm, then, connect a haulage cable in the front side of arm near deflecting roller place, through fixed supportOn stator wheel after its other end is connected with suspension hook, start winch, now, arm will taking deflecting roller as rotatePoint slowly erects, and when arm is erect to duty, takes off haulage cable, and mobile installation of arm becomeMust be more easy, as further scheme, then by leading truck, steel wire rope screw-button, shackle and guide plate installation in position,In Cargo Oil Pump lifting process, guide plate, along guiding steel wire upward sliding, has limited rocking that Cargo Oil Pump may occur, and separatesDetermine and caused Cargo Oil Pump to lift by crane difficult problem because cabin cabin altitude is too high, ensured Cargo Oil Pump putting down in lifting processStability and security.
