Description
Technical field
The present invention relates to a kind of transfer crane, be specifically related to a kind of tyred container door type crane.
Background technology
Tyred container door type crane or rail-mounted gantry container crane for harbour, harbour, goods yard is mainly the sectional construction being comprised of electrical motor, coupler, floating axle, drg, reductor, reel group, assembly pulley, steel rope etc. that adopts two traditional covers to be arranged symmetrically with to hoisting of goods at present.Not only oad is larger for this kind of structure, and Heavy Weight (if hoisting capacity is that its lifting mechanism weight of gantry container crane of 35t under suspender is mostly more than 10t), high, the whole manufacturing cost of maintenance cost are high; Tradition lifting mechanism mainly adopts steel rope to realize, steel rope belongs to flexible body, hoisting crane when to cargo transfer because of the startup of each mechanism of large dolly, stop or effect that wind carries is rocked greatly suspender or goods aloft, suspender or freight container be easy fitted not, production efficiency is low, is difficult to adapt to automatic cabinet storage yard operation; It is mainly to adopt many steel ropes to coordinate realization with winch that current minimizing suspender rocks large measure aloft, and which makes dolly assembly and complete machine control system become more complicated, and maintenance is inconvenient, the increase of dolly assembly weight, cost increase; Suspender balance regulator is mainly to adopt Electrohydraulic push rod and driving lever to realize, and degree of regulation is low, and can only regulate the balance of a direction; Vehicle structure is mostly crane in bridge type structure, and oad is large, Heavy Weight, and manufacturing cost is high; Tyred container door type crane traveling mechanism of the larger traveller drive axle mostly is band axle housing bridge pack arrangement, this structure compared with complicated, maintenance cost is high, Heavy Weight, required additional drive disk assembly are many, productive costs is high; Tyred container door type crane cart drive axle or driven bridge and vehicle frame are rigid attachment, roller tire self-deformation is realized vibration damping, if during crane running Uneven road, in same vehicle bridge, two ends tire force situation differs larger, roller tire self-deformation cannot be realized vibration damping and discharge a part of external force, will have a strong impact on the service life of vehicle bridge; Because lifting mechanism is the traditional sectional constructions of two covers, and will guarantee in hoisting capacity and lifting velocity situation, its power of motor needs larger, i.e. the electric components models such as the selected frequency converter of electrical control, resistor are also all larger, cause complete machine cost higher; Container spreader is added must arrange assembly pulley, and also must be provided with hoist cable; Because lifting mechanism is traditional sectional construction, and trolley frame top must be provided with the machine house that possesses rainproof heat insulating function, also must be provided with the hanging apparatus that meets this mechanism's maintenance use in machine house, causes dolly assembly weight to increase, and cost of manufacture is high; Because of trolley frame be traditional crane in bridge type structure and top be provided with machine house and following in Design of Steel Structural Element Sections increase, complete machine wind area is increased, affect complete machine stability.The added structure of container spreader also will increase simultaneously.For meeting hoist design specification requirement, above feature all can make the sectional dimension of the steel construction pieces such as crane girder, supporting leg, trolley frame strengthen, complete machine weight increases, and the models such as large wheeling mechanism motor, reductor increase, complete machine productive costs raises, and the market competitiveness reduces greatly.
