Abstract
The utility model relates to a gantry crane with a single main beam and an upper and a lower trolleys. The utility model comprises a gantry, a cart running mechanism and a trolley. A gantry main beam in the structure of double open-web trusses is welded by shaped iron, an upper and a lower ends of the gantry main beam are both provided with trolley tracks, wheels of an upper crane trolley are arranged on an upper track and the wheels of a lower crane trolley are hung on a lower track. The gantry crane with a single main beam and an upper and a lower trolleys of the utility model has novel structure, and because the gantry main beam adopts the structure of the double open-web trusses, the weight of the main beam is reduced; the design of the upper and the lower crane trolleys of the main beam causes that the function of the utility model is increased, and use ranges of the utility model are widened. The utility model can be used for single suspension and lift suspension, and the upper and the lower trolleys can be mutually alternated or penetrated for lifting operation. The utility model is suitable for loading, unloading, transporting and lifting work for projects with large elevating capacity, wide spans, multifunction and high efficiency, shipbuilding, etc. When a double-door type crane and a three-point statically determinating sling are adopted, the suspending and transporting operation of a bifilar beam of a high-speed railway can be carried out.
Description
Technical field
The utility model relates to transfer crane, and especially a kind of single girder is the double trolley transfer crane up and down.
Background technology
Along with the fast development of national economic development, the use of transfer crane more and more widely, the demand in market increases greatly.Existing transfer crane is made of door frame, traveling mechanism of the larger traveller, dolly, electrical appliance part etc., and dolly moves on the girder of door frame, and girder is because of structural relation, it only can be in the upper end or the lower end establish one or two dollies, functions of use is more single.At the engineering construction fabrication yard, having needs quick lifting framework of steel reinforcement, template, casting concrete, needs at a slow speed the heavy preformed part of handling steadily again, and these different actions often need two transfer crane work compounds just can finish.
Summary of the invention
The purpose of this utility model just provides a kind of novel structure, multi-functional, Yi Yitai alternative two with single girder double trolley transfer crane up and down.
Single girder of the present utility model double trolley transfer crane up and down comprises door frame, traveling mechanism of the larger traveller and dolly, traveling mechanism of the larger traveller and door frame supporting leg flexibly connect, the door frame girder adopts two vierendeel truss structures to be welded by shaped steel, the upper and lower end of door frame girder all is provided with trolley track, on the wheel of last crane carriage is placed on and gets on the right track, the wheel of following crane carriage is hung on lower railway, the upper end of door frame girder is provided with crane carriage on two platforms, and the lower end of door frame girder is provided with crane carriage under two platforms.
Single girder of the present utility model is double trolley transfer crane novel structure up and down, traveling mechanism of the larger traveller can walk around to, can on bend, walk, and has the buffer shock-absorbing effect, because the door frame girder adopts two vierendeel truss structures, and is made up of shaped steel, make door frame girder weight reduce greatly, welding capacity is few simultaneously, makes easy; The door frame girder is the design of two crane carriages up and down, makes that its function increases, range of use becomes wide, and the one platform can work as existing two transfer cranes usefulness.It can singly hang, lift, load onto suspension bracket and just can do the revolution lifting, also up and down double trolley is mutually alternately or pass through lifting operation, be suitable for loading and unloading and carrying lifting work such as big elevating capacity, large span, multi-functional, high efficiency engineering and shipbuilding, adopt two-door formula hoisting crane and 3 static determinacy suspenders also can carry out the lifting job of the large-scale beam of high speed railway.
