The specific embodiment

Embodiment 1:

Details are as follows for the technical solution of the towed step cooling bed of twin beams:

1, weight is difficult to the whole step rate bed surface made greatly again, resolves into several and the combination bed surface of the very light and handy stepping dolly of the segment distance of being separated by.

2, each stepping dolly all is made of liftable automotive chassis 21 and translation beam 6, there is wheel 19 in the liftable automotive chassis outside, walking realizes the rising and the decline of stepping dolly on the track of slope, carrying roller 20 is arranged in the liftable automotive chassis, supporting the horizontal movement of translation beam, translation beam can be realized " mouth " font movement locus on the stepping dolly.(Fig. 3)

3, the vehicle frame that is connecting all stepping dollies with a hoisting cross beam when hoisting cross beam moves, guarantees all dolly synchronization liftings.

4, connect translation beam in all stepping dollies with a translation crossbeam, can guarantee that when the translation crossbeam moves whole translation beams do level of synchronization and move.

5, when hoisting cross beam and translation crossbeam move according to certain rules, just draw the stepping dolly and carrying out synchronous well-regulated motion, forming a whole step rate bed surface.Cooperate the function of having finished translation beam " mouth " font movement locus with built-in beam again.

The course of work of the towed step cooling bed of twin beams is (seeing Fig. 1, Fig. 2):

1, rolled piece (for example 20# channel-section steel) enters approach table 8.

2, motor 18, reductor 17 driving lifting cranks 9 and translation crank 1 are done and are clockwise rotated, and lifting crank 9 drives hoisting cross beams 11 by lifting linking member 10 and does translational sideways movement.

3, hoisting cross beam 11 is connected with all stepping dollies 5, stepping dolly 7 by connecting rod 12, and the dolly 5 of stepping simultaneously is connected by connecting rod 16 with stepping dolly 7.So the translational motion of hoisting cross beam 11 drives whole stepping dollies and carries out lengthwise movement.

4, the wheel 19 on stepping dolly 5 and the stepping dolly 7 moves upward forward along slope track 13, has held up the translation beam 6 of stepping dolly 5 and stepping dolly 7 inside.Moving up and down of translation beam by stepping dolly 5 and 7 controls of stepping dolly, and its horizontal movement is by connecting rod 15 controls by translation crossbeam 14.When translation beam 6 began to be lifted, translation crossbeam 14 did not have translational motion, so translation beam 6 does not have horizontal movement.The rise of translation beam 6 has also just held up the rolled piece on roller-way 8 and built-in beam 4, and rolled piece also only rises simultaneously, does not have horizontal movement.

5, when the stepping dolly is lifted in 9 rotations of lifting crank, because translation crank 1 hysteresis 40-60 degree, so the bearing pin of translation crank 1 head moves downward, transverse movement seldom, and the head that connects the connecting rod 2 of translation crossbeam 14 is the strip groove, make its not stretchy translation crossbeam 14, so rolled piece does not have horizontal movement.(Fig. 4)

6, when stepping dolly 5 and stepping dolly 7 rose peak near the slope track, the bearing pin of translation crank 1 head was covered the idle stroke of rectangular groove, drives translation crossbeams 14 by connecting rod 2 and does horizontal movement.Translation crossbeam 14 drives translation beam 6 by connecting rod 15 and moves horizontally, and has realized that like this level of rolled piece moves forward.

7, after lifting crank 9 rotates 180 degree, continue to clockwise rotate, stepping dolly 5 is worked as in drive and stepping dolly 7 oppositely moves, and wheel moves downward along slope track 13, so rolled piece begins to descend.When translation crank 1 forwarded horizontal line 180 to and spends, rolled piece stopped to move horizontally forward, but still does descending motion.

8, after translation crank 1 turned over 180 degree, the head bearing pin was done reverse idle stroke motion again in rectangular groove, and translation crossbeam 14 does not have horizontal movement, so rolled piece does not have horizontal movement.After rolled piece continuation decline was placed in built-in beam 4, the bearing pin of crank 1 was just covered idle stroke, drove 14 repositions of translation crossbeam, and translation beam 6 disengaging rolled pieces also return horizontal original position later on simultaneously.

9, after finishing a stepwise operation, motor 18 stops, and all the other each parts also all stop at the home position, are waiting for the arrival of next rolled piece.In ordinary production, press the full rolled piece of certain distance row on the built-in beam 4, come one, walk one, make rolled piece on built-in beam, stop time enough, play the effect of cooling.Last process is that rolled piece is sent from runout table 3.

Embodiment 2:

The driving arrangement of hoisting cross beam and translation crossbeam can substitute the transmission of crank connecting link with rack-and-pinion or hydraulic cylinder, and other structure of the towed step cooling bed of twin beams is with embodiment 1.
