Abstract
The utility model relates to a rolling mill roll change supporting arrangement, including setting up base, hydro -cylinder, the supporting mechanism in the frame, supporting mechanism lower extreme articulates on the base, and the piston rod of hydro -cylinder is connected in the middle part of supporting mechanism and can be promoted to support the mechanism and rotates around the base, and during the roll change, the flexible end of hydro -cylinder drive supporting mechanism has supported the roller seat perpendicularly. The operating condition that the roller seat support perpendicularly in supporting mechanism only need be maintain to the hydro -cylinder, need not bear the gravity of roller seat, trades the gravity that is born the roller seat by supporting mechanism, and the load that the hydro -cylinder bore during the roll change always that has significantly reduced has effectively prevented the hydro -cylinder oil leak, reduction oil consumption, the loss that alleviates the hydro -cylinder, the life of improvement hydro -cylinder.
Description
Technical field
The utility model relates to a kind of mill roll supporting arrangement.
Background technology
Krause mill is provided with and organizes steel rider more, the steel rider of milling train is contained on roller seat, is installed in frame, is rolled processing by steel rider to steel plate by roller seat.In conventional art, mill roll generally uses oil cylinder vertical support to play roller seat and is born the weight of roller seat and steel rider by oil cylinder, because the weight of roller seat and steel rider is very large, and roll change needs the regular hour, oil cylinder bears very large load during roll change always, easily occurs oil leakage phenomenon, the hydraulic oil fuel consumption caused is large, contaminated environment, and easily damage oil cylinder, the life-span of reduction oil cylinder.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of mill roll supporting arrangement, and roll change process oil cylinder does not bear roller seat gravity, there will not be oil leakage phenomenon.
The utility model solves the technical scheme that its technical problem adopts:
A kind of mill roll supporting arrangement, comprise the pedestal be arranged in frame, oil cylinder, supporting device, described supporting device lower end is hinged on pedestal, the piston rod of described oil cylinder is connected to the middle part of supporting device and can promotes supporting device and rotate around pedestal, and described supporting device upwards rotates and vertical support can play roller seat.
Further, described supporting device is provided with two and connects an oil cylinder separately, and two oil cylinders are arranged on the inner side of supporting device.
Further, described supporting device is H type, and each supporting device is connected with two pedestals, and the piston rod of described oil cylinder and the tie point of supporting device are arranged on the side at H type supporting device center, and the top of supporting device is provided with roller.
Further, limiting block platform is provided with outside described roller.
Further, the cylinder body of described oil cylinder is connected with balance staff, oil cylinder can rotate around balance staff.
Further, described supporting device is coupled together by the screw thread of setting on it and the piston rod of oil cylinder.
The beneficial effects of the utility model are: supporting device lower end is hinged on pedestal, the piston rod of oil cylinder is connected to the middle part of supporting device and can promotes supporting device and rotate around pedestal, during roll change, the piston rod of oil cylinder drives the supporting device vertical support be connected on pedestal to play roller seat, oil cylinder only need maintain the duty that supporting device vertical support plays roller seat, the gravity of roller seat need not be born, the gravity of roller seat is born by supporting device, effectively prevent oil cylinder leakage of oil, reduce fuel consumption, alleviate the loss of oil cylinder, improve the service life of oil cylinder.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is lateral plan of the present utility model.
Detailed description of the invention
The lateral plan of the structural representation of this mill roll supporting arrangement as shown in Figure 1 and this mill roll supporting arrangement shown in Fig. 2, this mill roll supporting arrangement, comprise the pedestal 1 be arranged in frame, oil cylinder 2, supporting device 3, supporting device 3 lower end is hinged on pedestal 1, the piston rod of oil cylinder 2 is connected to the middle part of supporting device 3 and can promotes supporting device 3 and rotate around pedestal 1, during roll change, the piston rod of oil cylinder 2 drives supporting device 3 to rotate, and supporting device 3 vertical support can play roller seat.Oil cylinder 2 need maintain the duty that supporting device 3 vertical support plays roller seat, need not bear the gravity of roller seat, change the gravity being born roller seat by supporting device 3, effectively prevent oil cylinder 2 leakage of oil, reduce fuel consumption, alleviate the loss of oil cylinder 2, improve the service life of oil cylinder 2.
Roller seat is provided with guide rail, and supporting device 3 is provided with two and connects the inner side that an oil cylinder 2, two oil cylinders 2 are arranged on supporting device 3 separately.Supporting device 3 is in H type, and each supporting device 3 is connected with two pedestals 1, and the piston rod of oil cylinder 2 and the tie point of supporting device 3 are arranged on the side at H type supporting device 3 center, and the top of supporting device 3 is provided with roller 31.During roll change, guide rail by roller 31 vertical support, roller seat is pressed in roller 31 by guide rail, roller 31 by the gravity vertical transmission of roller seat to supporting device 3.Limiting block platform 311 is provided with outside roller 31.Roller seat can be really made steadily to skid off along original track.
The cylinder body of oil cylinder 2 is connected with balance staff 21, oil cylinder 2 can rotate around balance staff 21, is promoting the process of supporting device 3 rotation, and oil cylinder 2 is followed and rotated certain angle.
Supporting device 3 is connected with the piston rod of oil cylinder 2 by the threaded connector that it is arranged.Be threaded connection the position of the piston rod that suitably can adjust supporting device 3 and oil cylinder 2.During to guarantee roll change, the telescopic end of oil cylinder 2 drives supporting device 3 vertical support to play roller seat.
