Abstract
The utility model relates to a steel billet overturning machine, which comprises overturning mechanisms on both sides, wherein the overturning mechanism on each side comprises a revolving shaft, overturning claws, and a hydraulic cylinder for driving the overturning claws to rotate about the revolving shaft; more than two overturning claws are arranged on the overturning mechanism on each side; one revolving shaft is arranged on the overturning mechanism on the same side; each overturning claw of the overturning mechanism on the same side is fixedly connected with the revolving shaft of the overturning mechanism on the side. Compared with the prior art, the steel billet overturning machine has the advantages that the structure is simple; one revolving shaft is arranged on the overturning mechanism on the same side, and each overturning claw of the overturning mechanism on the same side is fixedly connected with the revolving shaft of the overturning mechanism on the side, so that absolute synchronization of each overturning claw on the same side can be ensured during overturning.
Description
Technical field
The utility model relates to steel works equipment, is specifically related to steel billet turnover machine.
Background technology
Some steel grade is sending the quality that needs block-by-block to check continuous casting steel billet upper and lower surface before hot-rolled process, remove the blemish such as crackle, scar producing, now strand temperature has 500～800 DEG C, need to use steel billet turnover machine 180 ° of turn-overs of strand, make lower surface upward so that check, handle again strand turned back.
The structure of the steel billet turnover machine of at present domestic some steel mill's equipment is continued to use the design of the VAI of offshore company, DANAELI etc. substantially, turnover machine is multijaw multi-cylinder, transmission separately, be that each pawl that turns over is rotated around self rotating shaft by a Driven by Hydraulic Cylinder, the synchronous realization with the rotational synchronization between rollover pawl by hydraulic cylinder.Because casting billet surface can not be desirable plane, adopt hydraulic synchronization will respectively turn over pawl control and in one plane can cause hydraulic cylinder force inequality, hydraulic system unbalance loading is serious, can not realize the design original intention that multijaw multi-cylinder all carries; It is longer that hydraulic cylinder is arranged vertically stroke, and the vertical dimension of whole device is larger, for convenience of checking that at Near Ground strand hydraulic cylinder can only be arranged in melt pit, is unfavorable for Maintenance and Repair; Turn over pawl and synchronously rely on hydraulic system realization completely, adjust quite complexity, and fault ratio of hydraulic pressure system is high, will affect equipment activity ratio.
Utility model content
Technical problem to be solved in the utility model is: a kind of steel billet turnover machine is provided, and it is simple in structure, homonymy turn-over mechanism respectively to turn over pawl synchronism good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of steel billet turnover machine, and it comprises both sides turn-over mechanism, each side turn-over mechanism includes rotating shaft, turns over pawl and turns over for driving the hydraulic cylinder that pawl rotates, and turns over pawl and rotates around the axis; The pawl that turns over of each side turn-over mechanism is more than two, and the rotating shaft of the same side turn-over mechanism is one, and the pawl that respectively turns over of the same side turn-over mechanism is all fixedly connected with the rotating shaft of this side turn-over mechanism.
In such scheme, steel billet turnover machine also comprises actuating arm, and one end of actuating arm and one end of described hydraulic cylinder are hinged, and the other end of actuating arm is fixedly connected with described rotating shaft.
In such scheme, steel billet turnover machine also comprises actuating arm, and one end of actuating arm and one end of described hydraulic cylinder are hinged, the other end of actuating arm with described in turn over pawl and be fixedly connected with.
In such scheme, the hydraulic cylinder of the same side turn-over mechanism is more than two, the hydraulic cylinder 1 oil circuit parallel connection of the same side turn-over mechanism.
The utility model is compared with prior art, simple in structure, and the rotating shaft of the same side turn-over mechanism is one, and the pawl that respectively turns over of the same side is all fixedly connected with the rotating shaft of this side turn-over mechanism, can ensure turn-over time, the same side respectively turn over pawl absolute synchronization.

Detailed description of the invention
Now by reference to the accompanying drawings the utility model embodiment is described, the utility model is not limited to following embodiment.
The utility model embodiment 1 as shown in Figure 1, it comprises both sides turn-over mechanism, each side turn-over mechanism includes actuating arm 5, rotating shaft 2, turns over pawl 3 and turns over for driving the hydraulic cylinder 1 that pawl rotates, and turns over pawl 3 and 2 rotates around the shaft; The pawl 3 that turns over of each side turn-over mechanism is 4, and the rotating shaft 2 of the same side turn-over mechanism is one, and the pawl 3 that respectively turns over of the same side turn-over mechanism is all fixedly connected with the rotating shaft 2 of this side turn-over mechanism.
As shown in Figure 3, one end of one end of actuating arm 5 and described hydraulic cylinder 1 is hinged, and the other end of actuating arm 5 is fixedly connected with described rotating shaft 2.
As shown in Figure 4, each hydraulic cylinder 1 provides power by integrated pump station valve platform 6, and the hydraulic cylinder 1 of the same side turn-over mechanism is two, the hydraulic cylinder 1 oil circuit parallel connection of the same side turn-over mechanism.
The utility model embodiment 2 as shown in Figure 2, it is substantially the same manner as Example 1, just, actuating arm 5 other ends with described in turn over pawl 3 and be fixedly connected with, actuating arm 5 and to turn over pawl 3 as a whole.
When the utility model work, turn over pawl 3 in the time of original state, turn over pawl 3 and be all horizontal (seeing a figure in Fig. 2), steel billet 4 is placed on a rollover pawl 3; Turn over pawl 3 in the time of rollover states, a side hydraulic cylinder 1 drives this rollover pawl 3 to rotate, and rotating shaft 2 drives the pawl 3 that turns over of homonymy to be synchronously rotated counterclockwise 110 ° and to stop (seeing the b figure in Fig. 2); The hydraulic cylinder 1 of opposite side drives another rollover pawl 3 to drive steel billet 4 to turn clockwise 70 ° to stop, now two rollover pawls 3 clamp steel billet 4 (seeing the c figure in Fig. 2), hydraulic cylinder 1 stops (seeing the d figure in Fig. 2) simultaneously simultaneously while driving two rollover pawls 3 to rotate drive steel billet 4 to upright position, then two rollover pawls 3 clockwise rotate 20 ° simultaneously and stop (seeing the e figure in Fig. 2), hydraulic cylinder 1 drives another rollover pawl 3 to clockwise rotate separately 70 ° to stop to original horizontal position, and now steel billet turnover machine completes steel billet turn-over (seeing the f figure in Fig. 2).
The turn-over process of the utility model steel billet turnover machine is reversible.
