Abstract
The utility model discloses a gantry crane for general use. The gantry crane for general use comprises a gantry which is composed of landing legs, a main girder, an articulated beam and a walking beam, wherein a cart walking mechanism is arranged on the walking beam; a bridge rail is arranged on the main girder; a bridge is arranged on the bridge rail; the bridge is composed of the walking beam and a bridge girder; a trolley track is arranged on the bridge girder; a self-propelled trolley is arranged on the trolley track; a hoisting mechanism is arranged on the self-propelled trolley; the cart walking mechanism comprises an angular rack, a cart drive motor, a cart brake, a cart speed reducer, a drive shaft, a driven shaft, a driving wheel and a driven wheel; a frequency sensitive rheostat is connected to a rotor winding loop of the cart drive motor. By adopting the gantry crane for general use, the cart stably starts or parks and operates stably; goods are stably and accurately conveyed; the service life of the crane is long.
Description
Technical field
The utility model relates to a kind of weight-lifting equipment, especially a kind of transfer crane.
Background technology
Transfer crane is that a kind of weight that makes to hang on crane hanger is at the weight-lifting equipment of spatial vertical lifting and parallel motion, be generally used for the warehouse of the open works such as industrial and mineral, harbour, Features of Railway Logistics goods station, loader and porter's work in stock ground, after the outfit lifting spreader, also can be used for lifting and the carrying of freight container.The cart of transfer crane of the prior art common squirrel-cage motor or the YZR serial motors of adopting drive more, this type of drive can make the unexpected acceleration or deceleration of door frame when cart starts or stop, the inertia that moment produces easily causes the damage of equipment or, by the significantly swing of hoisting thing, to lifting work, brings constant.
The utility model content
The technical matters that utility model will solve is: a kind of gantry crane for general use is provided, and this gantry crane for general use cart starts or parking operates steadily, and the goods handling is stable, accurate, the hoisting crane long service life.
The technical scheme that the technical solution problem is taked: a kind of gantry crane for general use, comprise by supporting leg, girder, articulated beam, the door frame that the ground walking beam forms, on the ground walking beam, be provided with cart walking mechanism, on girder, be provided with the crane span structure rail, on the crane span structure rail, be provided with crane span structure, described crane span structure is by walking beam, the crane span structure girder forms, on the crane span structure girder, be provided with trolley track, on trolley track, be provided with the self-propelled dolly, on automatic carriage, be provided with lifting mechanism, described cart walking mechanism is by angular frame, the cart drive motor, large vehicle brake, the cart reductor, axle drive shaft, driven shaft, driving wheel, follower forms, in the rotor winding loop of cart drive motor, be connected to frequency sensitive trheostat.
As improvement of the present utility model: on the trolley track of crane span structure, be provided with two self-propelled dollies.
As further improvement of the utility model: described hoisting mechanism for trolley comprises trolley drive motor, dolly transmission shaft, dolly reductor, double crosslinking drum, car brake, fixed pulley, movable pulley, steel rope, and hoisting limiter, load limiter are housed on the bearing seat of double crosslinking drum one end.
Beneficial effect: gantry crane for general use of the present utility model, owing to having adopted described gantry crane for general use to comprise by supporting leg, girder, articulated beam, the door frame that the ground walking beam forms, be provided with cart walking mechanism on the ground walking beam, on girder, be provided with the crane span structure rail, on rail, is provided with crane span structure, and described crane span structure is by walking beam, the crane span structure girder forms, and is provided with trolley track on the crane span structure girder, on trolley track, is provided with the self-propelled dolly, on automatic carriage, is provided with lifting mechanism, and described cart walking mechanism is by angular frame, the cart drive motor, large vehicle brake, the cart reductor, axle drive shaft, driven shaft, driving wheel, follower forms, in the rotor winding loop of cart drive motor, be connected to the technical scheme of frequency sensitive trheostat, by in the rotor winding loop at motor, connecing frequency sensitive trheostat, make motor more steady when starting and stopping, the inertia that while reducing cart startup or parking, moment produces, therefore, gantry crane for general use of the present utility model has the cart startup or parking operates steadily, and the goods handling is stable, accurately, the advantage of hoisting crane long service life, owing to having adopted the technical scheme that is provided with two self-propelled dollies on trolley track, but arbitrary dolly isolated operation or hoist while making gantry crane for general use specific works of the present utility model, two dollies also can be simultaneously in opposite directions or relative motion or hoist, by the lifting mechanism on two dollies, coordinate to complete weight is toppled over and upright operation, further expanded range of use and the application of gantry crane for general use of the present utility model, owing to having adopted described hoisting mechanism for trolley to comprise trolley drive motor, dolly transmission shaft, dolly reductor, double crosslinking drum, car brake, fixed pulley, movable pulley, steel rope, the technical characterictic of hoisting limiter, load limiter is housed on the bearing seat of double crosslinking drum one end, in the time of can preventing lifting cargo, overload, the superelevation phenomenon jeopardizes safety, further improved the safety performance of gantry crane for general use of the present utility model.
