Description

A kind of monkey

Technical field

The utility model relates to the crane in bridge type technical field, relates in particular to a kind of monkey.

Background technology

Crane in bridge type is widely used in places such as mine, metallurgy, harbour, and dolly is its core component.Known a kind of dolly 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 weight of dolly is big, also can increase the civil engineering cost of user's factory building.From the height angle, the tank floor of reductor is installed on the vehicle frame, and the fixed pulley group is installed on the downside of pulley beam, and its dolly whole height that the highest parts and minimum parts constituted is big, and 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.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of in light weight, monkey that whole height is little is provided, and this monkey support strength is big, is convenient to modularization production, and it 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 monkey, comprise main car frame, and electrical motor, reductor and reel are installed on it, 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.

Because 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, so 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 quality, 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, but this crane carriage also comprises subframe, and secondary jack up unit is installed on it that hinge is connected between main car frame and the subframe.Its effect is: be convenient to modularization production, also provide convenience for the user selects subframe as required simultaneously.During transportation, can with the major-minor vehicle frame separately reduce traffic cost.
