Description
Technical field
The utility model relates to the hoisting crane technical field, relates in particular to a kind of crane in bridge type.
Background technology
Crane in bridge type is widely used in places such as mine, metallurgy, harbour, mainly is made up of crane span structure, traveling mechanism of the larger traveller, electrical controller and dolly.Known crane in bridge type is equipped with major and minor jack up unit on its trolley frame, this trolley frame is a box type construction, and the pulley beam that supports fixed pulley is welded on the trolley frame.This pulley beam is a constrained beam, two fixed end not only will bear the gravity of vertical direction, but also to bear moment of flexure, because the most gravity that hoists of pulley joist support load, in order to improve its support strength, just must increase the oad of pulley beam and vehicle frame body, so, must increase the quality of dolly.Under the situation of same weight that hoists, it is the manufacturing cost height not only, and because the wheel load height of cart, also can increase the civil engineering cost of user's factory building.From the whole height angle, the tank floor of reductor is installed on the trolley frame, and the fixed pulley group is installed on the downside of pulley beam, its dolly whole height that the highest parts and minimum parts constituted is big, under the situation of same height that hoists, required factory building height increases cost.From effective lifting altitude, since the race direction of fixed pulley and reel to extend axially direction vertical, when reel rotates, steel rope is gone into the angle of the v-groove bigger variation can be taken place fixed pulley, when its angle is excessive, steel rope can damage the wheel rim of fixed pulley or take off groove, so suspension hook must be reserved certain distance with respect to trolley frame, damages pulley rim or takes off groove preventing.Its shortcoming is: the effective lifting altitude that has reduced hoisting crane.In addition, trolley frame is welded as a whole, and structure is loaded down with trivial details, is unfavorable for modularization production, and concerning the goliath with major and minor jack up unit, also can increases traffic cost.The girder and the walking beam of its big vehicle frame are welded as a whole, and increase traffic cost, and rail arrangement during trolley track adopts has strengthened the span of dolly, has increased the weight of dolly.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of crane in bridge type is provided, with overcome its dolly heaviness, whole height big, be not easy to the technical matters that modularization is produced, this crane in bridge type is low cost of manufacture not only, and can reduce the factory building cost for the user.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of crane in bridge type, comprise cart and dolly, electrical motor, reductor and reel are installed on the main car frame of dolly, described main car frame is formed four beam framed structures by two crossbeams and two longerons, between crossbeam and the longeron for removably connecting; The pulley beam two ends of supporting main fixed pulley are positioned over respectively on the bearing surface of two crossbeams, and this bearing surface is provided with and can limits the registration device that described pulley beam moves thereon, and described pulley beam is the box-like body of open lower side, and fixed pulley is installed on pulley beam inside.
Owing to adopted technique scheme, the pulley beam is positioned on the bearing surface of crossbeam, the qualification of its position relies on the registration device that is arranged on the crossbeam bearing surface to realize, so pulley beam two ends are single supported beam, its strong point only is subjected to the gravity of vertical direction, and it is stressed rationally, under the situation of same gravity that hoists, the oad of pulley beam is less, and is in light weight; Main car frame is four beam framed structures, and each beam effect is clear, and is simple in structure, thereby overall weight is light; Fixed pulley is installed on pulley beam inside, has reduced the whole height of dolly; For removably connecting, be convenient to the modularization manufacturing between crossbeam and the longeron.So the utility model is low cost of manufacture not only, and because the reduction of dolly weight, for the user has reduced the factory building cost.
As a kind of improvement, described motor mounting is being fixed on two platforms between the crossbeam, and the two ends of described reel are installed on respectively on two crossbeams, and the axis bearing of trend of reel is parallel with the race of described fixed pulley.Its effect is: when reel rotated, steel rope was gone into the angle of the v-groove and bigger variation can not taken place fixed pulley, thereby the distance that suspension hook is reserved with respect to trolley frame is short, had improved effective lifting altitude of hoisting crane.
As further improvement, described reductor supports and hangs on the wherein outside of a crossbeam by its input shaft and 2 of output shafts.The bottom of reductor can be extended to the trolley frame lower surface, thereby can further reduce the whole height of dolly.
Improve as another kind, the big vehicle frame of described cart is formed four beam framed structures by two girders and two walking beams, between girder and the walking beam for removably connecting.On the bearing surface of described girder trolley track is installed, this trolley track is that full rail is partially arranged.Its effect is: during transportation girder and walking beam are separated, be convenient to the modularization manufacturing, save traffic cost; Trolley track adopts full rail partially to arrange, can reduce the span of dolly, alleviates the weight of dolly.
