Abstract
The utility model relates to a cable winding drum for a crane, more specifically a winding drum of which the centre shaft weldment and the drum body adopt a composite connection form, and a shaft is not easy to fracture. The utility model solves the technical problem that the shaft of the cable winding drum of the existing crane is easy to fracture. The cable winding drum for a crane comprises a shaft coupling of the winding drum, the drum body, a centre shaft, a locking bolt component and a bearing, wherein the shaft coupling of the winding drum is arranged on one end surface of the drum body; the centre shaft is arranged on the other end surface of the drum body, the outer end of the centre shaft is arranged in the bearing, the centre shaft is welded with an end plate to form the centre shaft weldment which is welded and connected with a center plate inside the drum body, and the end plate of the centre shaft weldment is connected with a center plate outside the drum body through the locking bolt component. The centre shaft weldment which is solely manufactured carries out heat treatment for eliminating stress, mechanical processing treatment and ultrasonic examination, the fractured probability of the centre shaft is reduced, and the centre shaft is convenient to assemble and disassemble.
Description
Technical field:
The utility model relates to a kind of hoisting crane rope drum, more particularly, is that a kind of axis weldment, axis weldment and cylindrical shell of adopting adopts the not reel of easy fracture of compound connection form, axis weldment.
Background technology:
At present, for the hoisting crane cable drum of diameter greater than φ 2200mm, its axis adopts a single shaft (being axis), the bind mode of axis and cylindrical shell adopts the welding pattern usually, consult Fig. 1, rope drum comprises drum coupling 1, cylindrical shell 2, axis 3, bearing 4, is assembled into the hoisting crane reel with upper-part.The inboard of axis 3 and cylindrical shell 2 is connected by the welding pattern with outside former, for this structural shape product, can not stress-relieving by beat treatment and machine up after axis and cylindrical shell former weld, and welding quality can not guarantee to reach the ultrasonic flaw detection requirement; The leg of axis and outside former root is excessive, it is area of stress concentration herein, when frequent being subjected under bigger tensile stress, shearing force and the torque-combining effect of drum shaft, crackle at first produces from the leg (root) of axis and outside former, through expansion after a while, axis taking place down at last in working order rupture suddenly, causes catastrophic accident to take place.
Summary of the invention:
If the purpose of this utility model is to change behind axis fracture probability and the axle fracture conveniently in order to reduce, and a kind of hoisting crane rope drum of new connection form is provided, it can be convenient for changing after can reducing the probability of axle fracture and axle fracture.
Technical solutions of the utility model are: the hoisting crane rope drum: comprise drum coupling, cylindrical shell, axis and lock bolt assembly (comprising bolt, nut, pad), bearing, drum coupling is arranged on an end face of cylindrical shell, axis is arranged on another end face of cylindrical shell, the axis outer end is contained in the bearing, axis is changed system into the axis weldment that has end plate by an original single shaft, the end plate of axis weldment connects by lock bolt assembly (comprising bolt, nut, pad) and cylindrical shell outside former, and former is welded to connect in axis weldment and the cylindrical shell.
The beneficial effects of the utility model are, the leg root is difficult for cracking, and axis is easy fracture not, prolong the service life of reel, and Middle shaft assembly is convenient for changing.
Description of drawings:
Fig. 1 is the structural representation of existing rope drum.
Fig. 2 is the utility model structural representation.
Among the figure: 1-drum coupling, 2-cylindrical shell, 3-axis, 4-bearing, 5-end plate, 6-lock bolt assembly.
The specific embodiment: with reference to Fig. 2, the utility model is made of drum coupling 1, cylindrical shell 2, axis 3, lock bolt assembly 6 (comprising bolt, nut, pad), bearing 4 and end plate 5, and the outside former of reel 2 and the end plate 5 of axis 3 are carried out bolted connection; The inboard former of cylindrical shell 2 and axis weldment adopt welding manner, and the inboard former of axis weldment and cylindrical shell is that double groove is welded to connect.The axis weldment is independently made, promptly socket end plate 5 and welding are fixing on axis 3, the influence that the selection of welding axle is not welded, and bulk heat treatment stress-removal, machining processes mode are adopted in the welding back, weld seam is through the machine ground transition, and weld seam is through the ultrasonic flaw detection passed examination.Because the axis weldment independently is made and through bakingout process stress-removal, mechanical process, and ultrasonic flaw detection is qualified, therefore reduce the upward probability of weld seam generation tiny crack of axle, reduced the probability of axle fracture.If axle fracture then can be made another part axis weldment very easily and change.
The selected material and the cylindrical shell former of axle do not have coherence request, and the axis weldment is made the restriction that is not subjected to welding manner.
Claims (2)
1, hoisting crane rope drum, comprise drum coupling, cylindrical shell, axis, bearing, drum coupling is arranged on an end face of cylindrical shell, axis is arranged on another end face of cylindrical shell, the axis outer end is contained in the bearing, it is characterized in that: the axis welded end plate constitutes the axis weldment, and the inboard former of axis weldment and cylindrical shell is welded to connect, and the end plate of axis weldment and cylindrical shell outside former connect by the lock bolt assembly.
2, hoisting crane rope drum according to claim 1 is characterized in that: the inboard former of axis weldment and cylindrical shell is that double groove is welded to connect.
