Description
Technical field
The utility model relates to continuous casting production equipment, is specifically related to a kind of linkage of hydraulic pressure step cooling bed.
Background technology
On hydraulic pressure step cooling bed lifting synchronizing shaft and traversing synchronizing shaft, all there is the swing arm of some quantity, connecting at present between the swing arm of lifting synchronizing shaft and the swing arm of lifting beam and traversing synchronizing shaft and moving tooth is to realize by connecting rod and bearing pin, but due to lifting synchronizing shaft and traversing synchronizing shaft top link quantity many, and two synchronizing shaft length are all longer, when processing and installation, be difficult to guarantee the concentricity of each pin shaft hole in swing arm.So, if synchronizing shaft swing arm and lifting beam, moving tooth are connected with general connecting rod, non-adjustable due to length of connecting rod, it is asynchronous that the asynchronous meeting of each swinging arm of lifting synchronizing shaft causes that each lifting beam moves; In like manner, the asynchronous meeting of traversing each swinging arm of synchronizing shaft causes the asynchronous of the traversing action of each moving tooth, thereby affects the serviceability of whole equipment.
This uncontrollable connecting rod, higher to equipment requirement on machining accuracy, difficulty of processing is large, and processing cost is high, and on-the-spot installation accuracy has also been proposed to higher requirement, and installing/dismounting is not too convenient.
Utility model content
The utility model provides a kind of linkage of hydraulic pressure step cooling bed to be difficult to the defect of synchronizeing, installing/dismounting is inconvenient to overcome above-mentioned connecting rod with Sheng Liang, moving tooth.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: comprise lifting synchronizing shaft, oil cylinder and lifting beam, lifting synchronizing shaft is connected by swing arm with oil cylinder, lifting synchronizing shaft is connected by connecting rod with lifting beam, described lifting synchronizing shaft is provided with the first spherical hinge lug ring, described lifting beam is provided with the second spherical hinge lug ring, one end of connecting rod is connected with the first spherical hinge lug ring, the other end of connecting rod is connected with the second spherical hinge lug ring, the two ends of connecting rod are equipped with external screw thread, the externally threaded opposite direction at described connecting rod two ends, on described the first spherical hinge lug ring and the second spherical hinge lug ring, be equipped with the internal thread matching with the external screw thread of interlinking lever end.
The beneficial effects of the utility model are: the externally threaded direction at connecting rod two ends is set on the contrary, can realize when connecting rod need to lengthen, towards a direction pivot link, when connecting rod need to shorten, pivot link to another way, make that device structure of the present utility model is simple, easy to adjust, integral body has reduced equipment requirement on machining accuracy and matching requirements, reduced processing cost.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the external screw thread between the first spherical hinge lug ring and connecting rod is provided with the first locking nut, and the external screw thread between described the second spherical hinge lug ring and described connecting rod is provided with the second locking nut.
Adopt the beneficial effect of above-mentioned further scheme to be: locking nut plays fixation to the current length state of connecting rod.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is the cutaway view of connecting rod of the present utility model.
In accompanying drawing, the parts of each label representative are as follows:
1, the second spherical hinge lug ring, 2, connecting rod, the 3, first spherical hinge lug ring, the 4, first locking nut, the 5, second locking nut, 6, lifting synchronizing shaft, 7, swing arm, 8, oil cylinder, 9, lifting beam.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As depicted in figs. 1 and 2, a kind of linkage of hydraulic pressure step cooling bed, comprise lifting synchronizing shaft 6, oil cylinder 8 and lifting beam 9, lifting synchronizing shaft 6 is connected by swing arm 7 with oil cylinder 8, lifting synchronizing shaft 6 is connected by connecting rod 2 with lifting beam 9, described lifting synchronizing shaft 6 is provided with the first spherical hinge lug ring 3, described lifting beam 9 is provided with the second spherical hinge lug ring 1, one end of connecting rod 2 is connected with the first spherical hinge lug ring 3, the other end of connecting rod 2 is connected with the second spherical hinge lug ring 1, the two ends of connecting rod are equipped with external screw thread, the externally threaded opposite direction at described connecting rod two ends, on described the first spherical hinge lug ring and the second spherical hinge lug ring, be equipped with the internal thread matching with the external screw thread of interlinking lever end, externally threaded opposite direction due to connecting rod two ends, so the direction of the internal thread on the direction of the internal thread on the first spherical hinge lug ring 3 and the second spherical hinge lug ring 1 is also inevitable contrary.
Fig. 3 is the cutaway view of connecting rod of the present utility model, as shown in Figure 3, external screw thread between the first spherical hinge lug ring 3 and connecting rod 2 is provided with the first locking nut, external screw thread between described the second spherical hinge lug ring 1 and described connecting rod 2 is provided with the second locking nut, externally threaded opposite direction due to connecting rod two ends, therefore the hand of spiral of the first locking nut and the second locking nut is also contrary, when needs lengthen or shorten the length of connecting rod, first unscrew locking nut, until lever regulated to after suitable length again by locking nut screwing.
An embodiment of the present utility model is as follows: the external screw thread direction of connecting rod one end is left-handed, the external screw thread direction of the connecting rod other end is dextrorotation, accordingly, the internal thread of the first spherical hinge lug ring is left-handed, the internal thread of the second spherical hinge lug ring is dextrorotation, and the first locking nut and the second locking nut are corresponding also contrary with the hand of spiral at connecting rod two ends.During the utility model work, oil cylinder 8 piston rods rise long, by swing arm, drive lifting synchronizing shaft 6 to rotate, thereby can move right by drivening rod 2, when the action of connecting rod and swing arm is asynchronous, need connecting rod to regulate, when connecting rod need to extend, with spanner pivot link of direction shown in arrow 2 in Fig. 3, and stubborn locking nut; In like manner, when length of connecting rod need shorten, with spanner, rotate backward connecting rod 2, and tighten locking nut.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
