Abstract
The invention relates to a device and a method for quickly replacing a transmission shaft of a horizontal rolling mill of a vertical rolling mill hung on the front and back sides, wherein the device comprises a big hook head and a small hook head, and is characterized in that the device consists of a walking trolley and a trolley capable of moving relatively on the trolley, the track of the trolley is a working roll changing track, and a rolling wheel set is arranged on a rack on the transmission side. Through the quick replacement of the transmission shaft of the horizontal rolling mill by the device, the problem that the main transmission connecting shaft of the horizontal roughing mill with the front and rear back-hanging vertical rolls cannot be replaced is solved, and the time for replacing can be greatly shortened. The device has the advantages of convenient operation, reasonable structure, high working efficiency and the like.
Description
Technical field
The present invention relates to the horizontal mill power transmission shaft quick replacement device and the method for a kind of replacing device and method of plant equipment, particularly front-rear back hanging vertical miller.
Background technology
Along with the development of steel rolling technology, short flow process rolling technique has obtained using widely, and this technology consumes energy is few, and rolling rhythm is fast, can significantly reduce costs, and generates profit.In short flow process technology, the designer has adopted the technology of a roughing mill, strengthens the frame section rigidity of milling train, increases the transmission roll-force, realizes the heavy reduction rolling of hot base, thereby shortens the whole piece flowline.Produced the control problem of width with the application of this method, a vertical miller is difficult to satisfy the problem of spreading that is produced under the heavy reduction situation, so the designer has adopted the horizontal roughing mill of front-rear back hanging vertical miller formula to overcome difficulties.
Use after this milling train, difficulty has appearred in the replacing of main transmission connecting axle, because traditional roughing mill has only preceding edger roll, its connecting axle can slave after leaving space change fast, but front and back are all installed after the vertical miller, the space that connecting axle does not just hoist and rotates does not just have the possibility of changing yet.So it is the problem that solve that the replacing connecting axle solves the difficulty that runs in the reality.
Summary of the invention
The horizontal mill power transmission shaft quick replacement device and the method that the purpose of this invention is to provide a kind of front-rear back hanging vertical miller of easy to operate, rational in infrastructure, high efficiency.
The horizontal mill power transmission shaft quick replacement device of front-rear back hanging vertical miller, comprise big gib head, little gib head, it is characterized in that: this device is made of the chassis of traveling and the dolly that can relatively move on chassis, the track of chassis is to utilize the work roll changing track, is provided with the rolling wheels on the transmission side frame.
The horizontal mill power transmission shaft quick change method of described front-rear back hanging vertical miller, it is characterized in that: during dismounting, connecting axle is sling with big gib head and little gib head, surpass the chassis height, then an end of connecting axle is placed on the dolly on the chassis, starting crane drive connecting axle moves to the active side frame, connecting axle rolls on the rolling wheels, rolling wheels drive connecting axle drags dolly and moves on chassis, center of gravity until connecting axle moves within the chassis support scope, dolly and connecting axle above chassis drives are then changed connecting axle along track to the grinding roller workshop; Installation process adopts opposite process.
Compared with prior art, advantage of the present invention is:
Enforcement has by this method not only solved the difficult problem that the horizontal roughing mill main transmission of front-rear back hanging vertical miller formula connecting axle can't be changed, and changes the used time and also can shorten greatly.Advantages such as that this device has is easy to operate, rational in infrastructure, operating efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
See Fig. 1,, a kind of front-rear back hanging vertical miller horizontal mill power transmission shaft quick replacement device, this device is made of the chassis (7) of traveling and the dolly (4) that can relatively move on chassis (7), the track of chassis (7) is to utilize work roll changing track (5), is provided with rolling wheels (9) on transmission side frame (8).Above transmission side frame and active side frame, be provided with entablature (3).
Its course of work is: during dismounting, connecting axle (10) is sling with big gib head (1) and little gib head (2), surpass chassis (7) highly, then an end of connecting axle (10) is placed on the dolly (4) on the chassis (7), starting crane drive connecting axle (10) moves to active side frame (6), connecting axle (10) is gone up at rolling wheels (9) and is rolled, rolling wheels (9) drive connecting axles (10) drag dolly (4) and go up mobile at chassis (7), center of gravity until connecting axle (10) moves within chassis (7) the support scope, dolly (4) and connecting axle (10) above chassis (7) drives are then changed connecting axle (10) along track (5) to the grinding roller workshop.
Installation process adopts opposite process.
Claims (2)
1, the horizontal mill power transmission shaft quick replacement device of front-rear back hanging vertical miller, comprise big gib head (1), little gib head (2), it is characterized in that: this device is made of the chassis (7) of traveling and the dolly (4) that can relatively move on chassis (7), the track of chassis (7) is to utilize work roll changing track (5), is provided with rolling wheels (9) on transmission side frame (8).
2, the horizontal mill power transmission shaft quick change method of front-rear back hanging vertical miller according to claim 1, it is characterized in that: during dismounting, connecting axle (10) is sling with big gib head (1) and little gib head (2), surpass chassis (7) highly, then an end of connecting axle (10) is placed on the dolly (4) on the chassis (7), starting crane drive connecting axle (10) moves to active side frame (6), connecting axle (10) is gone up at rolling wheels (9) and is rolled, rolling wheels (9) drive connecting axles (10) drag dolly (4) and go up mobile at chassis (7), center of gravity until connecting axle (10) moves within chassis (7) the support scope, dolly (4) and connecting axle (10) above chassis (7) drives are then changed connecting axle (10) along track (5) to the grinding roller workshop; Installation process adopts opposite process.
