The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1,2, of the present invention swing type cold bed, comprise cold bed bed surface 8, it is characterized in that by one group of lower end and basis 1 draft link that is connected 3, be connected the little axle 5 of these draft link 3 upper ends, little axle 5 connecting rods that link together 11 with each draft link upper end, be connected the driving mechanism 12 of these connecting rod 11 1 ends, respectively with little axle 5 upper pendulum bars that are connected 6 of each draft link upper end, be connected two spacing poles 4 at an angle of these upper pendulum bar 6 lower ends, be connected the Material moving device of these upper pendulum bar 6 upper ends and therewith the cold bed bed surface 8 that is complementary of Material moving device form.
As shown in Figure 1, described Material moving device moves material crossbeam 9 for what be connected with upper pendulum bar 6 upper ends by rotating shaft 7, draft link 3, connecting rod 11, upper pendulum bar 6, moves the common composition of material crossbeam 9 and moves the material quadric chain.
As shown in Figure 2, described Material moving device is a ratchet 13, and ratchet 13 lower ends are provided with balance weight iron 14 (referring to accompanying drawing 5), and draft link 3, connecting rod 11, upper pendulum bar 6, ratchet move the material quadric chain 13 common compositions.
At described driving mechanism 12 is the crank rocking arm power quadric chain that is driven through decelerator by motor, and this crank rocking arm power quadric chain is connected with the connecting rod that moves the material quadric chain by turning cylinder.
Be rotatably connected by following turning cylinder 2 and basis 1 in described draft link 3 lower ends.
Make motion analysis referring to 3 pairs of first kind of embodiments of accompanying drawing.It shown in the figure unit in the sleeve mechanism.When draft link 3 when the O point is swung from left to right, the summit of upper pendulum bar 6 is that the A point turns right along camber line ABCD, when forwarding the B point to, move material crossbeam 9 just with cold bed bed surface 8 places at grade, section bar 10 is just moved material crossbeam 9 and is held up, and moves right.After moving to the highest C point, continue to move down to the right.When moving to the D point, move material crossbeam 9 and just locate at grade again with cold bed bed surface 8.When upper pendulum bar 6 continued to be moved downward to the E point to the right, by the effect of gravity and stop, upper pendulum bar 6 was around draft link 3 summit O
1Rotate and changed the position of stop.This moment, draft link 3 also arrived the right side extreme position, beginning back turns left, and the summit of upper pendulum bar 6 turns left along camber line EFG, until forwarding the A point to, owing to the effect of gravity, upper pendulum bar 6 forwards the limit inferior position counterclockwise to again, and upper pendulum bar 6 summits are turned back to initial position, sleeve mechanism stops, once more material loading and enter next circulation.
The motion analysis that 4 pairs of another embodiments of accompanying drawing are done is roughly close with the motion analysis that first kind of embodiment done, and is just held up by ratchet 13 and transports section bar 10, rather than move the material crossbeam and hold up and transport section bar.Ratchet 13 is free state at the A point.At this moment put for the normal off-position of Material moving device.When needs move material, ratchet 13 turns right along camber line ABCD, and when moving to position B, the angle of cut of doing the ratchet two sides of compound motion just contacts with section bar bottom surface on the cold bed bed surface, because the weight of section bar and with the effect of the frictional force of cold bed bed surface, force ratchet with draft link 3 summit O
1Rotation limits until limited device.At this moment ratchet and draft link are rigid of transmission on rotation direction, and along with the rotation of fork, ratchet lifts section bar gradually and leaves the cold bed bed surface, this moment section bar center of gravity and the center of rotation O of ratchet
1In level side factory a distance upwards arranged, the weight of section bar distance therewith produces an anticlockwise moment, the reaction moment balance of the limited device of this moment falls.Just because of the effect of this trimming moment, when fork is rotated further, does not just cause ratchet counter-rotating, thereby section bar can not fallen down, but steadily along the camber line C position that moves right.This moment, fork ran near the upright position, and section bar rises near peak, the center of gravity of section bar and the center of rotation O of ratchet
1Horizontal range obviously dwindle, moment is also dwindled thereupon.But because fork has a speed continuing operation to the right, and because the effect of frictional force, section bar rests on the ratchet always.Treat that operation puts when putting D the center of gravity of section bar and the center of rotation O of ratchet in place
1Distance become negative value, moment becomes clockwise direction, section bar begins to glide along the horizontal contact-making surface of ratchet, and inclination is arranged slightly, its front end just contacts with the cold bed face.At this moment, since most of weight of section bar still by pawl-bearing, so though contact with the cold bed face, it is very little to rub, so noise is also very little.When fork ran to position E, two plane angles of ratchet just contacted with the cold bed face, and section bar is lain on the cold bed face.This moment, fork swung to the right side extreme position.Along with the continuation operation of driving mechanism, fork begins next shuttling movement.
Swing type cold bed characteristics of the present invention are: individual construction is simple, and is in light weight, and volume is little, Be easy to make, require the processing precise degree not high, be convenient to installation and debugging, and required driving force is little; Section bar leaves the cold bed bed surface, and, nothing friction contactless with the cold bed bed surface made an uproar thereby eliminated fully Sound; Compare with present cold bed, can save steel construction piece and basic 40-50%, can save energy 30-40%, Power consumption is the 70-60% of same level cold bed.
