The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of notch-bar cooling bed on hot finished steel pipe or type steel production line, comprise the multiple fixed rack and multiple carry-over bar alternately arranged successively by spacing, multiple fixed rack is positioned on two built-in beams at two ends across being bearing in, be equipped with in the lower end of two built-in beams and multiplely determine beam support, it is characterized in that: comprise carry-over bar supporting structure and carry-over bar driving mechanism, described carry-over bar supporting structure comprises two power transmission shafts that the below that is arranged on multiple carry-over bar parallels, two power transmission shafts are supported on the axle bed that is arranged at below it by respective bearing block, position corresponding up and down with each carry-over bar on two power transmission shafts is all provided with an eccentric wheel, each eccentric above be equipped with one group and move beam support, often the dynamic beam support of group is formed with two bogie wheels being arranged on dynamic beam support lower end by moving beam support, two bogie wheels form Structure deformation with corresponding eccentric wheel, many groups corresponding to every root power transmission shaft are moved the walking beam being equipped with above beam support and being fixedly connected with corresponding multiple dynamic beam support, the bottom of walking beam and carry-over bar forms a fixed connection, described carry-over bar driving mechanism comprises motor and by motor-driven two decelerators, the output of two decelerators drives with two power transmission shafts respectively and is connected.
The technical scheme that the utility model can also be taked is:
Every root power transmission shaft is axially laid with multiple balancing weight.
The advantage that the utility model has and good effect are:
This notch-bar cooling bed, drives eccentric wheel to rotate the reciprocating motion realizing carry-over bar by motor, and then achieves the step-by-step movement displacement of rolled piece on cold bed.The speed of service of this cold bed is realized by the rotating speed controlling motor, and the motion due to whole carry-over bars is realized by the rotation of two power transmission shafts, and therefore, the synchronism of the operation of cold bed is better, and controls fairly simple.In addition, this cold bed eliminates baroque hydraulic system, therefore also simplify structure and reduces device fabrication cost, in addition, it also avoid hydraulic system maintenance shortcoming costly, reduce the maintenance cost of equipment.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-3, a kind of notch-bar cooling bed on hot finished steel pipe or type steel production line, be made up of following a few part:
Comprise the multiple fixed racks 1 and multiple carry-over bar 2 alternately arranged successively by spacing, multiple fixed rack is positioned on two built-in beams 3 at two ends across being bearing in, and is equipped with multiplely to determine beam support 4 in the lower end of two built-in beams.
Comprise carry-over bar supporting structure.Described carry-over bar supporting structure is comprised and is arranged on two power transmission shafts, 5, two power transmission shafts paralleled below multiple carry-over bar and is supported on by respective bearing block 6 on the axle bed 7 that is arranged at below it.Position corresponding up and down with each carry-over bar on two power transmission shafts is all provided with an eccentric wheel 8.Each eccentric above be equipped with one group and move beam support 9, often the dynamic beam support of group is made up of two the bogie wheel 9-2 moving beam support 9-1 and be arranged on dynamic beam support lower end, and two bogie wheels form Structure deformation with corresponding eccentric wheel.Many groups corresponding to every root power transmission shaft are moved the walking beam 10 being equipped with above beam support and being fixedly connected with corresponding multiple dynamic beam support, and the bottom of walking beam and carry-over bar is fixed by securing member and is connected.
Comprise carry-over bar driving mechanism, described carry-over bar driving mechanism comprises motor 11 and is driven with two power transmission shafts respectively by the output of motor-driven two decelerators 12, two decelerators and is connected, and like this, can drive two power transmission shaft synchronous rotaries by two decelerators.
In said mechanism, every root power transmission shaft is axially laid with multiple balancing weight 13 further.Concrete, be arranged on the center of gravity of all balancing weights on same power transmission shaft in the side of power transmission shaft, and all eccentric center of gravity be arranged on this root power transmission shaft is positioned at the opposite side of power transmission shaft, and the center of gravity of all balancing weights, eccentric center of gravity and drive shaft axis are at grade.Owing to being provided with multiple eccentric wheel on power transmission shaft, the torque of eccentric wheel and load generation on it on a part of power transmission shaft can be balanced by arranging balancing weight, thus the torque of power transmission shaft is reduced, so not only can improve the service life of power transmission shaft, and motor, the capacity of decelerator and load can be reduced, play the effect of energy-saving consumption-reducing.
The operation principle of this notch-bar cooling bed is:
Rolled piece after hot rolling is sent on cold bed, and rolled piece is supported on fixed rack; Motor rotation, rotated by decelerator, power transmission shaft band movable eccentric wheel, eccentric wheel often revolves and turns around, carry-over bar completes feeding, moves a station on fixed rack, blowing, action to the wait position of next rolled piece.Carry out again and again by certain procedures like this, complete the work of the cooling of rolled piece on cold bed, aligning, translation.
