Abstract
The utility model discloses a novel large-hoisting-capacity stationary portal crane, which is applied to land-water transshipment operations of heavy cargos. A main girder of the portal crane stretches across a land area and a water area, and four supporting legs are all immovably fixed; the supporting legs on land are fixed on the ground, and the supporting legs in water are fixed on two supporting platforms built under water by way of island building; the supporting legs on land are fixed on the ground by foundation bolts, and the supporting legs in water are hinged with hinge supports on the supporting platforms by way of pin shaft connecting; and a car system lifts and brings down heavy cargos and drives heavy cargos to operate along a track of the main girder so as to complete the land-water transshipment of the heavy cargos. The arrangement pattern of a trolley set and a balance beam in a cart travel mechanism of a common portal crane is introduced in a car system operation mechanism, and therefore, the pressure loads on the track of the main girder and a wheel are effectively reduced.
Description
Technical field
The utility model relates to a kind of weight-hauling equipment, relates in particular to a kind of transfer crane that is used for great land of harbour-water transhipment.
Background technology
Novel big elevating capacity fixed type transfer crane is mainly used in the wharf apron, and effect is that great is loaded and unloaded on the ship by land or by loading and unloading land on the ship, promptly accomplish land-water transfer operation of great.
Relevant regulations according to Department of Transportation's " road large-sized object transportation administration way " are divided into level Four with large-sized object by its oad and weight, and progression is high more, and profile more greatly or heavy more.Wherein the level Four large-sized object is meant and reaches one of standards person: length is more than 40m reaches; Width is more than 6m reaches; Height is more than 5m reaches; Weight is at 300t and following." great " described herein is above-mentioned level Four large-sized object.
Common transfer crane generally is applied to the stockyard, is used for the pile and the transition operation of freight container or breakbulk, and hoisting capacity is many at 30-50t, can't bear great the weight more than 300 tons; And common transfer crane can't be accomplished great land-water transfer operation only in the land-based area operation.The bank crane in bridge type can be accomplished freight container land-water transfer operation through overhanging cantilever, but hoisting capacity also is limited in 30-50t.
Summary of the invention
The big elevating capacity fixed type transfer crane that the utility model proposes is different from the common transfer crane of universal.The one, its hoisting capacity is big, reaches 500t, can satisfy general great requirement that hoists; The 2nd, it is across land-based area and waters, and four door legs are all fixed.Land side door leg is fixed on ground, and water side door leg is fixed in the water to build on two support platforms that the island mode builds up.Land side door leg and ground are fixed through holding-down bolt, and the hinged-support on water side door leg and the support platform is hinged with the bearing pin connecting mode; The 3rd, it is applied to wheeling mechanism with chassis group equalizing bar pattern in the common gate-type crane operating unit, efficiently solves girder rail pressure problem.
Four door legs are all fixed.Land side door leg is fixed on ground, and water side door leg is fixed in the water to build on two support platforms that the island mode builds up.Land side door leg and ground are fixed through holding-down bolt, and the hinged-support on water side door leg and the support platform is hinged with the bearing pin connecting mode.
The technical scheme of the utility model is: big elevating capacity fixed type transfer crane is across land-based area and waters, and great is transported in its land side strides by flat truck, and the lifting mechanism on the cart system hoists great through steel rope; After hoisting, cart system operating unit action, the dolly band great along the girder orbital motion to the waters; After operation stopped, lifting mechanism dropped to weight on the barge that rests between waters door leg and the wharf apron.Water-Lu transport process is opposite.
The beneficial effect of the utility model is to have solved indeterminable great the land of common transfer crane-difficult problem of water transfer loading and unloading ship.Than other land-water transfer handling equipment such as runabout crane, fixed type rotary crane, mast crane, floating crane and fixed type crane in bridge type, have advantages such as small investment, short, detachable transition of duration.

The specific embodiment
Among Fig. 1, a kind of big elevating capacity fixed type transfer crane of the utility model comprises girder 1, land side door leg 2, water side door leg 3, vehicle structure frame 4, lifting mechanism 5, operating unit 6, rich rope system 7, suspension hook group 8, hinged-support 9 etc.Complete machine is across land-based area and waters, and land side door leg 2 is all fixed with water side door leg 3.Land side door leg 2 is fixed with supporting cushion cap through holding-down bolt, and water side door leg 3 is with the bearing pin connection mode and be fixed on hinged-support 9 hinged securement on the water side support platform.Vehicle structure frame 4, lifting mechanism 5, operating unit 6 are formed cart system.This machine cart system has only 1 cover, and it is to express cart system to rest in land side and two diverse locations of water side that two cover cart systems and two weights are arranged among Fig. 1.Lifting mechanism hoists great through rich rope system 7 or descends, and operating unit can drive cart system zero load or load running.During great land-water transhipment, vehicle-mounted great of flat truck is parked in transfer crane strides, and barge rests between water conservancy project cushion cap and the wharf apron; Steel rope one end is fastened at the other end on great and is fastened on suspension hook group 8, and lifting mechanism 5 twines the rolling steel rope through reel great is hoisted; Operating unit 6 electric motor startings, cart system band great along the girder orbital motion to the water side.To correct position, operating unit 6 is out of service, and lifting mechanism 5 is transferred on the barge deck great.Land-water transfer operation is accomplished.
Show among Fig. 2 that the door machine is two main beam structures, land side and water side respectively have two door legs.Totally two overlap the suspension hook groups.
Among Fig. 3, chassis group equalizing bar 10, wheel 11, the three-in-one motor 12 common operating units 6 of forming.Two cover operating units 6 are arranged on 2 on the every girder, and complete machine has quadruplet operating unit, 16 wheels.11 walkings of three-in-one motor 12 drive wheels drive whole cart system operation.Great weight is carried the wheel 11 of trolley travelling and the track 13 on the girder 2 and is born very big pressure more than 300 ton.Chassis group equalizing bar had before only appeared at common gate-type bridge crane operating unit.This machine is introduced equalizing bar 10 in wheeling mechanism 6 after, 16 wheels of efficient balance 11 carry, and have alleviated track 13 pressure.
