Abstract
The invention discloses a straight bar type link chain gangway lifting device. The device comprises a chain accommodating bin (1), a base (2), a link chain cucurbit (3), a link chain (4), a chain cable fairlead (5), a vertical rod (6), a vertical rod seat (7), a chain cable case (8), a hanger (9), a main rigging (11), a hanging ring (11) and other main parts. The device has the characteristics of small volume of a lift mechanism, light weight of a support structure, small assembly area, high lifting extent and the like, is easy to maintain and can be used for lifting chip gangway or similar workpieces.
Description
Technical field
The present invention relates to a kind of springboard bont peculiar to vessel, particularly relate to a kind of straight-bar type loop chain springboard bont.
Background technology
Extensively adopt the springboard of motor-driven lifting to realize that ship-bank connects on the boats and ships, and the springboard bont that uses at present is the steel wire rope winch-bont of cranking arm, this bont has the following disadvantages: 1. because the nominal diameter of steel wire rope winch reel is to determine by curved characteristic and mechanism's working level of steel rope, according to its barrel dliameter of design regulation/rope footpath 〉=14 (GB/T 3811-2008), so drum diameter can not be little; 2. the steel rope of steel wire rope winch redundancy can only be stored on the reel, and Rong Shengliang is big more, and the diameter of reel and length are just big more, so winch is bulky; 3.L shape crank arm can make suspender extend to suspension centre directly over, make the stressed minimum of winch and steel rope.But because the horizontal length of cranking arm is longer, the cross section is thicker, and the horizontal projected area of cranking arm above deck is also big, so floor area is big; 4.L the maximum lift elevation angle that shape is cranked arm and limited springboard.5. owing to the moist steel rope of working environment gets rusty easily, difficult in maintenance.5. the weight and volume of the steel wire rope winch under the identical hoisting capacity is greater than the loop chain cucurbit.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, utilize loop chain cucurbit compact conformation, storage chain not to take that the deck available space is vertical with montant to be installed, and lifting amplitude characteristics such as big (maximum elevations can reach≤90 °) realize the lifting task of springboard peculiar to vessel or similar working substance.
The present invention is achieved by the following scheme.Straight-bar type loop chain springboard bont comprises appearance chain storehouse, support, loop chain cucurbit, loop chain, fairleader, montant, montant seat, leads chain cover, suspender, main rope tool, suspension ring etc.
Loop chain cucurbit and montant are installed in respectively on support and the montant seat, and support has and holds the chain storehouse, and redundant loop chain is stored in the appearance chain storehouse.Montant is the circular straight-bar of thin-walled, and self-supporting is installed, and the upper surface of bar is equipped with and is led chain cover, and the lower surface is equipped with flange and is connected with the montant seat, and fairleader and tethers eye plate are installed on the body of rod.Loop chain one end lies in the eye plate on the montant, and the sprocket wheel that the other end is walked around the loop chain cucurbit enters and holds the chain storehouse and the tethers ring is fixed.Loop chain is equipped with fairleader respectively and leads chain cover in the turning point.The two ends of main rope tool respectively with springboard on suspension ring link to each other with suspender on the loop chain.Suspender one end is that sprocket wheel cooperates with loop chain, and the other end is the first chain link of U-shaped hitcher and main rope tool, links together by bearing pin, and the U-shaped hitcher can be around self axis rotation.The loop chain cucurbit is horizontal installation, and Lifting slings has been to reuse short link chain, and redundant loop chain is stored in and holds in the chain storehouse, and the loop chain cucurbit comprises taper bridge motor, retarder, drive sprocket and electric control system, provides propulsion source for finishing the springboard operation.
Principle of work: start power supply, the sprocket wheel rotation that the motor-driven on the loop chain cucurbit links to each other with retarder, the electric control system on the operation cucurbit, the gear teeth on the sprocket wheel and loop chain engagement and traction loop chain pulling springboard are done the luffing motion.The spring of motor forces cone rotor and stator to embrace and brake when stopping.For preventing that chain from reversing, and is provided with chain guide device in the turning point.Montant makes chain stressed rationally in order to obtain to pull the moment of springboard.
Straight-bar type loop chain springboard bont involved in the present invention adopts loop chain cucurbit-montant lift technique, and following advantage is arranged: 1. the working portion of loop chain cucurbit has only pair of sprocket, and volume is very little; 2. the storage chain of loop chain cucurbit holds the idle space that structure can be used in the chain storehouse not on the cucurbit body; 3. montant is installed perpendicular to the deck, and it is few to take floor space; 4. lifting amplitude is big; 5. the loop chain plating zinc on surface is anticorrosion, is difficult for getting rusty.If meet the paintable protection of corrosion, safeguard simple.
