Electricity drives the coil of strip slewing arrangement
Technical field:
The utility model relates to a kind of metallurgical machinery, is specifically related to a kind of electricity and drives the coil of strip slewing arrangement.
Background technology:
Be transported to for the ease of coil of strip in the production facilities of next flow process, need adjust coil of strip and take the lead the direction of opening, this just needs a coil of strip slewing arrangement.Existing coil of strip slewing arrangement adopts Driven by Hydraulic Cylinder usually, by the rack pinion transmission straight-line motion is converted to gyroscopic movement, and structure is comparatively complicated, and this device only rotates coil of strip 90 degree usually.If coil of strip need increase the anglec of rotation (as increasing to 180 °), then must strengthen the stroke of hydraulic actuating cylinder, thereby cause device structure huge, investment also increases thereupon.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of electricity to drive the coil of strip slewing arrangement at the deficiency of above-mentioned prior art existence, and its compactness rational in infrastructure can be rotated coil of strip to any angle.
The utility model is that the technical scheme that technical matters adopted of the above-mentioned proposition of solution is: comprise coil of strip carriage and the base for supporting that fixes on the ground, what they were different is, between coil of strip carriage and base for supporting, pivoting support is installed, pivoting support is connected successively by outer ring, bearing, inner ring and forms, outer ring and coil of strip carriage are fixedly connected, inner ring is fixedly connected on base for supporting, the outer ring of pivoting support is provided with external tooth, the gear of outer ring and pinion transmission, miniature gears is driven by the frequency conversion gear motor.
The beneficial effects of the utility model are: (1) has increased the anglec of rotation of coil of strip, thereby guarantees that coil of strip can rotate to the optional position; (2) compactness rational in infrastructure, mounting or dismounting are convenient, for ease of maintenaince; (3) adopt the frequency conversion gear motor, can adjust the rotative speed of coil of strip.

Specific embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, coil of strip 4 is placed on the coil of strip carriage 3.Between coil of strip carriage 3 and the base for supporting 6 that fixes on the ground pivoting support 5 is installed, pivoting support 5 is made of outer ring 7, bearing 8, inner ring 10, the outer ring 7 of described pivoting support is provided with external tooth, outer ring 7 and inner ring 10 are equipped with tapped bore, outer ring 7 is fixedly connected by bolt 11 and coil of strip carriage 3, and inner ring 10 is fixedly connected on base for supporting 6 by bolt 11.Key on the frequency conversion gear motor output shaft cooperates with the miniature gears 2 that has keyway, and Drive pinion rotates.Outer ring 7 meshed transmission gear of miniature gears 2 and pivoting support; Because the inner ring of pivoting support is fixed,, rotate thereby drive the coil of strip carriage 3 that is fixedly mounted on the outer ring 7 so outer ring 7 can be turned round around inner ring.
The utility model can make 360 ° of rotations of coil of strip carriage.
