Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, the present embodiment provides a rotary steel-dialing device, which includes a rotary table 1, a beam 2, a wheel 3, a finger 4, a rail frame 5, a wheel rail 6 and a driving device 7.

Wherein, the rotary table 1 is fixedly installed on the installation object, and the top thereof is provided with a hinge point 10.

The beam 2 is a box-shaped steel structure member, and is guaranteed not to deform easily under the heat radiation of a steel billet. The cross beam 2 comprises a first cross beam 21 and a second cross beam 22 which are arranged at a certain included angle, one ends of the first cross beam 21 and the second cross beam 22 are mutually combined and hinged on a hinge point 10 of the rotary table 1, so that the first cross beam 21 and the second cross beam 22 can rotate around the hinge point 10 of the rotary table 1 at a fixed included angle. And the other ends of the first cross beam 21 and the second cross beam 22 far away from the revolving platform 1 are fixedly provided with a wheel 3.

And a plurality of pusher dogs 4 are arranged on the first cross beam 21 and the second cross beam 22, and the plurality of pusher dogs 4 on each cross beam are respectively arranged at intervals along the length direction of the cross beam.

The rail frame 5 is a steel billet rail arranged in a fan shape, so that the first beam 21 and the second beam 22 can push the steel billet 8 to move on the rail frame 5 when rotating. A plurality of track frame units with different distances are arranged in the rotating angle of the rotary steel pulling device, so that the rotary steel pulling device is suitable for steel billets with different length specifications.

The wheel tracks 6 are arranged in a sector and are matched to the wheels 3. Preferably, limit stops are arranged at the starting position and the end position of the wheel track, so that the wheels are prevented from being separated from the track due to signal loss or misoperation.

The driving device 7 is fixedly arranged on the end part of the first beam 21 or the second beam 22 far away from the rotary table, and is in driving connection with the wheels on the beam on which the driving device is arranged so as to drive the wheels 3 to run on the wheel tracks 6. Since there is only one driving device 7, one of the wheels 3 on the first beam 21 and the second beam 22 is a driving wheel, and the other is a driven wheel. In the present embodiment, the driving device 7 is a gear motor, so that the driving device 7 can have a large torque.

The utility model provides a rotatory steel device of dialling's operation principle as follows:

when the driving device 7 is in standby, the rotary steel-shifting device is in a waiting position (see fig. 2), when the driving device 7 is powered on by a signal, the cross beam 2 rotates clockwise around the hinge point 10 of the rotary table 1, and the pusher dog 4 on the cross beam pushes the billet 8 on the track frame 5 to rotate synchronously.

When the gear motor of the driving device 7 is operated for a period of time (see fig. 3), the billet in the waiting position is rotationally shifted to the middle position, and the billet in the middle position is rotationally shifted to the extreme position, so that the billet can enter the downstream process.

Then the driving device 7 rotates reversely to the original position, so that the pusher dog 4 of the beam 2 can receive the next billet in the billet waiting position, then the driving device 7 rotates forwards to repeat the previous action, at the moment, the billet which is initially in the waiting position reaches the middle position, the previous action reaches the extreme position, and the downstream process can be carried out. So far, after the gear motor runs for two times, the billet rotates to the downstream position by a certain angle from the horizontal position, and one period is finished. The start, acceleration, deceleration and stop of the driving device 7 can be realized by an encoder and a proximity switch, and the control of the driving device 7 is prior art, and therefore will not be described herein.

The rotary steel-shifting device provided by the embodiment is designed with a structure of middle and double-beam relay steel-shifting, so that the rotation angle of the rotary steel-shifting device can be reduced by half, the transfer time of steel billets can be reduced, and the operation rhythm of equipment can be improved.

Referring to fig. 4, in the present embodiment, the cross beam 2 on the rotary table 1 is of a cantilever design, so that in order to overcome the tilting moment of the cross beam 2 due to its own weight and to overcome the torque transmitted to the pusher dog by the billet friction on the rail during the steel-stripping, a rotary support 11 is provided in the rotary table 1. The slewing bearing is composed of an inner ring, an outer ring and a rolling body positioned between the inner ring and the outer ring, is a large bearing capable of bearing comprehensive loads, and can simultaneously bear larger axial and radial loads and overturning moments.

Referring to fig. 5-8, in the present embodiment, the finger 4 is pivotally connected to a side wall of the first beam 21 or the second beam 22 through a rotating shaft 41, and the finger 4 has an upper portion facing the side wall of the first beam 21 or the second beam 22 and a lower portion extending below the first beam 21 or the second beam 22. The side wall of the first beam 21 or the second beam 22 is also provided with a stop block 42 which is opposite to the upper part of the pusher dog 4.

As shown in fig. 5, when the beam 2 carries the pusher 4 to move gradually toward the billet waiting position, the pusher 4 contacts the billet 8 during the traverse. Referring to fig. 6, since the finger 4 is pivotally connected to the beam 2 in a pin structure, the finger 4 rotates around the rotating shaft to sweep over the billet to reach the billet waiting position, which is shown in fig. 7. The beam 2 then carries the pusher dog 4 to the right, and when the pusher dog 4 again comes into contact with the billet, see fig. 8, the pusher dog 4 cannot rotate any further because the upper end of the pusher dog 4 has already abutted against the stop 42, and can therefore push the billet further on the rail housing. And the steel receiving action of the pusher dog is finished.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
