Description
Technical field
The present invention relates to a kind of gantry crane, be specifically related to a kind of tyred container door type crane.
Background technology
It is currently used for harbour, harbour, the tyred container door type crane of goods yard or the rail-mounted gantry container crane fabricated structure being made up of motor, shaft coupling, floating axle, brake, reductor, reel group, assembly pulley, steel wire rope etc. mainly adopting two traditional sets to be arranged symmetrically with that hoists to goods.This kind of structure not only overall dimensions is relatively big, and Heavy Weight (as lifting capacity be under suspender its lifting mechanism weight of the gantry container crane of 35t mostly at more than 10t), maintenance cost manufacturing cost high, overall high；Tradition lifting mechanism mainly adopts steel wire rope to realize, steel wire rope belongs to flexible body, crane when to cargo transfer because the effect of the startup of each mechanism of big dolly, stopping or wind load makes suspender or goods aloft rock greatly, suspender or container not easy fitted, production efficiency is low, is difficult to adapt to automatic cabinet storage yard operation；Current minimizing suspender aloft rocks big measure and mainly adopts many steel wire ropes to coordinate realization with hoist engine, and which makes dolly assembly and complete machine control system become more complicated, and maintenance is inconvenient, and the increase of dolly assembly weight, cost increase；Suspender balance regulator mainly adopts Electrohydraulic push rod to realize with driving lever, and degree of regulation is low, and can only regulate the balance in a direction；Vehicle structure is mostly bridge crane structure, and overall dimensions is big, 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 parts are many, production cost is high；Tyred container door type crane cart drive axle or driven bridge are rigid attachment with vehicle frame, roller tire self-deformation realizes vibration damping, if during crane running Uneven road, in same vehicle bridge, tire force situation difference in two ends is bigger, roller tire self-deformation cannot realize 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 fabricated structures of two sets, and under ensureing lifting capacity and lifting velocity situation, its power of motor needs relatively big, and namely the electric components model such as converter selected by electrical control, resistor is also all relatively big, causes that complete machine is relatively costly；The added assembly pulley that must arrange of container spreader, and hoist cable must also be provided with；Because of the fabricated structure that lifting mechanism is traditional, and must being provided with the engine house possessing rainproof heat insulating function above trolley frame, must also be provided with the hanging apparatus meeting the maintenance of this mechanism, cause that dolly assembly weight increases in engine house, cost of manufacture is high；Because of trolley frame be traditional bridge crane structure be arranged over engine house and be following in Design of Steel Structural Element Sections increase, make complete machine front face area increase, affect complete machine stability.The structure that container spreader is added simultaneously also will increase.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 model increases, complete machine production cost raises for big wheeling mechanism motor, reductor etc., and the market competitiveness is substantially reduced.
Summary of the invention
It is an object of the invention to provide the tyred container door type crane of a kind of simple in construction, lightweight, low cost of manufacture.
This tyred container door type crane disclosed by the invention, including the traveling mechanism of the larger traveller being sequentially connected with from the bottom up, supporting leg, girder and dolly.Traveling mechanism of the larger traveller mainly includes driving vehicle bridge and driven vehicle bridge, and dolly mainly includes trolley frame, wheeling mechanism and lifting mechanism, and trolley frame is connected to lifting mechanism, and the lower end of lifting mechanism is connected to sling upper rack, and the lower end of sling upper rack is connected to suspender.Described trolley frame is made up of U-shaped girder, end carriage and crossbeam, two butt beams are connected to the two ends of two single u-shaped girders, two crossbeams are connected between two girders about the length direction symmetry of U-shaped girder, the outside of U-shaped girder two minor face is connected with end carriage and the either flush of end carriage, and its base is sunken to below end carriage；Described lifting mechanism includes hydraulic power unit and multistage hydraulic cylinder, and hydraulic power unit is installed on the top of trolley frame, and multistage hydraulic cylinder is installed on the lower section of crossbeam, and the hydraulic valve of hydraulic power unit controls the synchronization telescope action of multistage hydraulic cylinder；Described driving vehicle bridge includes power transmission shaft and is connected to sprocket wheel and the sprocket wheel flange of propeller shaft length direction middle position, sprocket wheel flange and sprocket wheel connect as one, sprocket wheel is by sprocket wheel flange and is installed on the chain on sprocket wheel and is connected with the driving mechanism of crane to drive complete machine to run, the lateral symmetry of power transmission shaft upper sprocket wheel is connected to bearing and bearing block, bearing block is connected to support complete machine with the driving vehicle frame of crane, the two ends of power transmission shaft are symmetrically connected with rim shoulder, rim shoulder is connected with the wheel rim of wheel the power of driving mechanism to pass to wheel to realize complete machine operation.
Described multistage hydraulic cylinder has four, they two ends being respectively arranged in described crossbeam in rectangular layout, ball-type articulated joint is passed through hinged between their cylinder barrel upper end and described crossbeam, during to eliminate crane big trolley travelling linkage work, the impact on oil cylinder of rocking of suspender or goods affects, its piston-rod lower end is hinged by bearing pin and described sling upper rack, so that sling upper rack simple in construction is lightweight.When simultaneously aforementioned hinge connected mode can make crane work relative to flexible steel wire rope, suspender or goods aloft rock and little much make the container spreader under sling upper rack or container para-position convenient, and efficiency height is completely suitable for automatic cabinet storage yard operation.
