Abstract
The invention relates to a roll-up slewing gear, comprising a support, swing cylinders and a coil platform, wherein the support is of a frame structure, and is fixed on a roll-up trolley through bolts; the swing cylinders are suspended and fixed at the lower part in the support through bolts; the coil platform is horizontally arranged at the top of the support and supported by a bearing below; the bearing is fixed on the support through a bolt; a connecting shaft is arranged at the center of the bottom surface of the coil platform, passes through the support, is fixed into a keyway hole of the swing cylinders, and is driven to rotate by the swing cylinders. The roll-up slewing gear is simple in structure and safe and reliable in performance; the roll-up trolley can sleeve a coil on an uncoiler no matter what direction the head of the coil is in, and the head of the coil is in the uncoiling direction all the time.
Description
Technical field
The invention belongs to field of metallurgical equipment, particularly the upper rollback rotary device of cold rolling unit.
Background technology
In field of metallurgical equipment, particularly, in cold rolling unit, band twists in before volume, takes the lead to be in the direction (being all generally upper uncoiling) of uncoiling, so must place the roll coil of strip by direction on fixed saddle.Cause increasing labour intensity, operating efficiency is low.
Summary of the invention
In order to solve the roll coil of strip of prior art existence, need according to upper uncoiling direction, place in advance, increase labour intensity, reduce the problem of operating efficiency, the invention provides a kind of upper rollback rotary device, simple in structure, performance safety is reliable, no matter be with tape head in any direction, upper volume dolly can be enclosed within the roll coil of strip on uncoiler, and guarantees the taking the lead all the time in uncoiling direction of the roll coil of strip.
The present invention is achieved through the following technical solutions:
A upper rollback rotary device, comprises bearing, oscillating oil cylinder and roll coil of strip platform, and bearing is frame structure, is bolted on volume dolly, and oscillating oil cylinder is fixed on below, bearing inside by hung bolt; Roll coil of strip platform is horizontally disposed at bearing top, and by the bearings of its below, bearing is bolted on bearing, and roll coil of strip platform bottom center is provided with connecting axle, and connecting axle is fixed in the dowel hole of oscillating oil cylinder through bearing, by oscillating oil cylinder driven rotary.
Further, roll coil of strip platform is activity V-type head, and its upper surface centre position broad ways is provided with V-type groove, and extends to roll coil of strip platform both sides.
Further, the V-type angle of V-type groove is 120 degree, and the free degree of V-type groove is constrained to 2.
Further, the upper surface of roll coil of strip platform has wearing layer.
The orientation that the present invention drives roll coil of strip platform to realize horizontal direction by oscillating oil cylinder is determined angle and is rotated, and no matter is with tape head in any direction, and upper volume dolly can be enclosed within the roll coil of strip on uncoiler, and guarantees the taking the lead all the time in uncoiling direction of the roll coil of strip.And roll coil of strip platform employing activity V-type head, realizes the stable arrangement of the roll coil of strip by the V-type groove on it, lick on can be not again and in journey, depart from roll coil of strip platform.In addition, the wearing and tearing of the roll coil of strip to the it when wearing layer of roll coil of strip platform surface can be avoided using for a long time, the service life of prolongation roll coil of strip platform.The present invention is simple and compact for structure, and without manual intervention, performance safety is reliable, can be widely used in the upper volume equipment of cold rolling unit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1: roll coil of strip platform; 2: bearing; 3: bearing; 4: oscillating oil cylinder; 5: connecting axle; 6:V type groove.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As described in Figure 1, the invention provides a kind of upper rollback rotary device, comprise bearing 2, oscillating oil cylinder 4 and roll coil of strip platform 1, bearing 2 is frame structure, is bolted on volume dolly, and oscillating oil cylinder 4 is fixed on the inner below of bearing 2 by hung bolt; Roll coil of strip platform 1 is horizontally disposed at bearing 2 tops, bearing 3 by its below supports, bearing 3 is bolted on bearing 2, roll coil of strip platform 1 bottom center is provided with connecting axle 5, described connecting axle 5 is fixed in the dowel hole of oscillating oil cylinder 4 through bearing 2, dowel hole by oscillating oil cylinder 4 passes to rotation torque the connecting axle 5 of roll coil of strip platform 1 bottom center, and then drives roll coil of strip platform 1 rotation in the horizontal direction.Move by a tooth bar of apply piston bar promotion of hydraulic oil in oscillating oil cylinder 5 inside, piston can stop at an arbitrary position, to realize rotation at any angle.In any direction, upper volume dolly can be enclosed within the roll coil of strip on uncoiler opinion band tape head, and guarantees the taking the lead all the time in uncoiling direction of the roll coil of strip.
Meanwhile, roll coil of strip platform 1 is activity V-type head, and its upper surface centre position broad ways is provided with V-type groove 6, and extends to roll coil of strip platform 1 both sides.Preferably, the angle of V-type is 120 degree, and the free degree of V-type groove 6 is constrained to 2.Object has six-freedom degree in space, the rotation of the movement of three directions and three directions, and when two object links form after kinematic pair, relative motion between the two is just subject to certain constraint.The utilization of V-type groove 6 makes object (being the roll coil of strip) thereon only have the movement of a direction and the rotation of a direction, can guarantee rouleau can guarantee again large roll stabilizing in wherein.After the roll coil of strip is placed on roll coil of strip platform 1, by the V-type groove 6 on it, realize the stable arrangement of the roll coil of strip, lick on can be not again and in journey, depart from roll coil of strip platform.
In addition, the upper surface of roll coil of strip platform 1 has wearing layer, can be fixed by screws in roll coil of strip platform 1 surface.The wearing layer of V-type groove 6 should have certain hardness to also have certain wearability, so that can not abrade the surface of the roll coil of strip.Because band twists on roll coil of strip platform 1, install continually and unload, roll coil of strip platform 1 is had to very large wearing and tearing.Wearing layer can be avoided the wearing and tearing of roll coil of strip platform 1, extends the service life of roll coil of strip platform 1.
In sum, the present invention is simple and compact for structure, without manual intervention, by can realize the orientation of the roll coil of strip to the control of oscillating oil cylinder, determines angle and rotates, and performance safety is reliable, can be widely used in the upper volume equipment of cold rolling unit.
The parts that the present invention does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
