The utility model is mainly used in various cold rolling mills.
Description
Technical field
The utility model relates to cold-rolling mill, refers more particularly to the bracing or strutting arrangement of transmission connecting shaft in the cold-rolling mill.
Background technology
At present, the bracing or strutting arrangement of transmission connecting shaft mainly is made up of carriage, screw rod, bracing frame, adjusting nut etc. in the domestic common cold-rolling mill.In actual use, this bracing or strutting arrangement has and need adjust from location, two sides, and operating process is cumbersome; And its centering adjusting function is relatively poor, causes support hook to contact not exclusively with transmission connecting shaft, makes transmission connecting shaft produce wearing and tearing, has shortened the service life of transmission connecting shaft, has increased production cost; And this bracing or strutting arrangement can not be eliminated the impact that produces because of beating of transmission connecting shaft, makes its overall structure performance instability, not only can not support well transmission connecting shaft, also can have influence on rolling accuracy.
The utility model content
Technical problem to be solved in the utility model is: a kind of easy to operate, centering better performances is provided and can eliminates the bracing or strutting arrangement of transmission connecting shaft in the cold-rolling mill of impact of transmission connecting shaft.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the bracing or strutting arrangement of transmission connecting shaft in the cold-rolling mill, comprise: base, base is provided with column, be movably hinged with on the column and the corresponding support hook of transmission connecting shaft, the hook of support hook head is arranged to the circular arc that matches with transmission connecting shaft, the neck of hook of support hook afterbody is provided with the fork plate, also be provided with support on the described column, the end of support is provided with bearing, is equipped with screw rod in the bearing, and the upper end of screw rod is provided with handwheel, the lower end of screw rod is provided with damping spring, and the bottom of damping spring is resisted against on the fork plate.
The lower end that the lower end of described screw rod is provided with the lead, lead and the screw rod that adapt with damping spring forms step, and this step is pressed on the top of damping spring.
Described screw rod is arranged in the bearing by bolt and nut, that is: bolt and nut is located in the bearing, and described screw rod is located in the bolt and nut by screw thread.
The beneficial effects of the utility model are: of the present utility model easy to operate; Be movably articulated in the support hook on the column, can make transmission connecting shaft in the process of roll change, obtain positioning performance preferably, carry out roll change smoothly; In addition, damping spring can be eliminated the centrifugal force that the circular runout because of transmission connecting shaft produces, make that the structural behaviour of whole bracing or strutting arrangement is stable, not only can support well transmission connecting shaft, rolling accuracy is ensured reliably, reduce the wearing and tearing of transmission connecting shaft, thereby prolonged the service life of transmission connecting shaft, reduced production cost.

Among Fig. 1 to Fig. 3: 1, base, 2, handwheel, 3, screw rod, 31, lead, 4, junction of the edges of two sheets of paper screw, 5, bearing, 6, bolt and nut, 7, damping spring, 8, the fork plate, 9, support hook, 91, hook, 92, the neck of hook, 10, bearing pin, 11, column, 12, fixing hole, 13, transmission connecting shaft, 14, support.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, the bracing or strutting arrangement of transmission connecting shaft in the cold-rolling mill described in the utility model, comprise: base 1, base 1 is provided with column 11, be movably hinged with and transmission connecting shaft 13 corresponding support hook 9 by bearing pin 10 on the column 11, the hook 91 of support hook 9 heads is arranged to the circular arc that matches with transmission connecting shaft 13, the neck of hook 92 of support hook 9 afterbodys is provided with fork plate 8---referring to shown in Figure 3, also be provided with support 14 on the described column 11, the end of support 14 is provided with bearing 5, bearing 5 is equipped with bolt and nut 6 by junction of the edges of two sheets of paper screw, bolt and nut 6 is equipped with screw rod 3 by screw thread, and the upper end of screw rod 3 is provided with handwheel 2, and the lower end of screw rod 3 is provided with guide pillar 31, the step that the lower end of screw rod 3 and guide pillar 31 form is pressed on the damping spring 7 that adapts with lead 31, and the bottom of damping spring 7 is resisted against on the fork plate 8; Also be provided with 4 fixing holes 12 that are used to install foundation bolt on the described base 1---referring to shown in Figure 2.
The course of work of the present utility model is: when milling train quits work and send signal, for reducing and eliminate the rotator inertia of transmission connecting shaft 13 generations, rotatable handwheel 2, make screw rod 3 move downward, moving downward of screw rod 3 makes damping spring 7 be compressed, the spring force that damping spring 7 is compressed the back generation acts on the support hook 9, support hook 9 is that rotate at the center with bearing pin 10, that is: the neck of hook 92 declines, the hook 91 of support hook 9 rise, the hook 91 of support hook 9 can steadily, fully be held transmission connecting shaft 13, thereby can successfully carry out roll change; When milling train is started working, by reverse rotation handwheel 2 (fine setting), make screw rod 3 slowly move upward, it is that rotate at the center with bearing pin 10 that the moving upward of screw rod 3 makes support hook 9, that is: the neck of hook 92 risings, hook 91 descend, and damping spring 7 reduces decrements, and hook 91 still touches on the cylindrical of transmission connecting shaft 13, play the effect of buffering transmission connecting shaft rotator inertia, damping spring 7 makes transmission connecting shaft 13 form flexible the contact with the hook 91 of support hook 9.
