The utility model discloses a setting has the slide of elasticity reset function, has solved the vertical rolling mill cardan shaft and has leaded to the frequent cracked problem of rotary trunnion in-plane bearing fragile, rolling mill end bulging tooth apron bolt because of long-time atress is uneven, easily installs and maintains simultaneously, has improved cardan shaft life.
Description
Technical Field
The utility model belongs to the technical field of steel rolling production line technique and specifically relates to a edgewise roll cardan shaft bracket elevating gear.
Background
In a steel rolling production line system, a universal shaft is a main transmission device for connecting a speed reducer and a roller, and a universal shaft bracket plays roles in supporting, fixing and limiting the universal shaft. Under the influence of the field working condition of a two-roll mill and the installation error of a mill flat head body and a cardan shaft in production practice, rigid connection adopted between an original bracket and a vertically rolled cardan shaft cannot well adapt to the errors, so that the axial stress of a plane bearing in a rotary trunnion of the cardan shaft is large, a drum-shaped tooth cover plate bolt at the end of the mill can also bear large torque load in the transmission process, frequent faults of the plane bearing and the drum-shaped tooth cover plate of the vertically rolled cardan shaft are easy to occur, the service life of the vertically rolled cardan shaft is shortened, and the influence of the bracket on the working state of the vertically rolled cardan shaft is necessarily reduced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome not enough among the prior art, the utility model provides a edgewise roll cardan shaft bracket elevating gear to under the bad condition of rolling mill operating mode condition, reduce the opposite influence of rolling cardan shaft operating condition of bracket.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a roll cardan shaft bracket elevating gear immediately, includes base support, bracket and cardan shaft, base support side seted up vertical spout, bracket one end and vertical spout sliding fit, the slide is installed to the bracket bottom surface, the slide in slide and be equipped with the slider, the cardan shaft be located the bracket inboard, the rotatory gudgeon and the slider of cardan shaft are connected, the slide pass through stud and be connected with the bracket bottom surface, stud on the cover be equipped with reset spring and support and press the backing plate in the reset spring outer end, the last adjusting nut who presses in the backing plate that is connected with of stud.
Furthermore, a lifting cylinder is installed on the base support, and a piston rod of the lifting cylinder is connected with the bracket through a pin shaft.
The utility model has the advantages that: the utility model discloses a suit reset spring on the double-end screw who connects slide and bracket utilizes the elasticity reset function that the slide has, has solved the vertical rolling mill cardan shaft and has easily damaged because of long-time atress inequality leads to the plane bearing in the rotatory trunnion, the rolling mill end bulging tooth apron bolt problem of frequent fracture, easily installs and maintains simultaneously, has improved cardan shaft life.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the bracket of the present invention.
Fig. 3 is an enlarged schematic view of a structure at a in fig. 2.
In the figure: 1. the device comprises a base support, 2, a bracket, 3, a universal shaft, 4, a sliding seat, 5, a sliding block, 6, a double-end screw, 7, a return spring, 8, a backing plate, 9, an adjusting nut, 10 and a lifting cylinder.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 to 3, the lifting device for a bracket of a universal shaft for vertical rolling comprises a base support 1, a bracket 2 and a universal shaft 3, wherein a vertical sliding groove is formed in the side surface of the base support 1, one end of the bracket 2 is in sliding fit with the vertical sliding groove, a lifting cylinder 10 is installed on the base support 1, and a piston rod of the lifting cylinder 10 is connected with the bracket 2 through a pin shaft to push the bracket 2 to move up and down.
2 bottom surfaces of bracket install slide 4, slide 4 in slide and be equipped with slider 5, cardan shaft 3 be located 2 inboards of bracket, the rotatory trunnion and the slider 5 of cardan shaft 3 are connected, slide 4 be connected with 2 bottom surfaces of bracket through double-end screw 6, stud 6 on the cover be equipped with reset spring 7 with support and press the backing plate 8 in reset spring 7 outer end, be connected with on the double-end screw 6 and press in the adjusting nut 9 of backing plate 8.
Above-mentioned structure realizes the elastic expansion of slide 4 through reset spring 7 effect, has reached the cardan shaft 3 and the complete match of rolling mill flat head body under the dead weight effect, and reset spring 7 ensures the non-clearance connection of slider 5 and slide 4 in the vertical direction.
In the working process, a piston rod of the lifting cylinder 10 extends out to drive the bracket 2 and the universal shaft 3 to descend to the connecting position with the rolling mill, the piston rod of the lifting cylinder 10 retracts, the bracket 2 drives the rolling mill to ascend to the rolling position, the universal shaft 3 is always in matched connection with a rolling mill flat head body under the action of self-weight, the axial stress of a plane bearing in a rotary trunnion on the universal shaft 3 is basically only the pre-tightening force provided by the reset spring 7, the axial stress of a drum-shaped tooth cover plate bolt at the end of the rolling mill is correspondingly reduced, the torque load on the cover plate bolt is small in the rotating process of the rolling mill, and the cover plate bolt is not easy to break.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
