In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a rolling mill pressure head replacement instrument, includes fixed platform, lift platform, elevating gear, base, the base is fixed in fixed platform's bottom, lift platform sets up in fixed platform's both sides to with fixed platform sliding connection, elevating gear drive lift platform lifts or descends, the pedestal mounting has the wheel.
Fixed platform includes manual operation platform, frame slide, elevating gear mounting panel, manual operation platform fixes between two frame slides, the frame slide is the square frame that forms by four angle steel A and the welding of horizontal muscle roof beam, elevating gear arranges in the square frame and slides with four angle steel A cooperations, the elevating gear mounting panel is fixed in the square frame, the below of elevating gear platform, elevating gear arranges in between elevating gear mounting panel and the elevating platform.
The lifting platform comprises an upper platform, a lower fixing plate and angle steel B, the upper platform and the lower fixing plate are respectively fixed at the upper end and the lower end of the four angle steel B, and the four angle steel B of the lifting platform are matched with the four angle steel A of the frame slide way to slide.
And a roller changing trolley hook head is also fixed at one end of the base.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a rolling mill pressure head replacement instrument, can dismantle the pressure head as the support frame to can transport the pressure head outside the rolling mill alone and change, transport back again and install in the rolling mill, need not to pull down the backing roll, shorten the repair time, reduce public auxiliary unit energy lost power cost, lift platform and fixed platform are at the inside wide flat manual work space that forms of rolling mill, personnel's operation is convenient, easy operation, can not take place the injury of falling, the operation factor of safety who improves.

Detailed Description
The following further describes the embodiments of the present invention:
see fig. 1, a rolling mill pressure head replacement instrument, including fixed platform 3, lift platform 1, elevating gear 5, base 4 fixes in fixed platform 3's bottom, lift platform 1 sets up in fixed platform 3's both sides to with fixed platform 3 sliding connection, elevating gear 5 drive lift platform 1 lifts or descends, wheel 14 is installed to base 4.
Fixed platform 3 includes manual operation platform 2, frame slide, elevating gear mounting panel 12, manual operation platform 2 is fixed between two frame slides, the frame slide is the square frame that forms by four angle steel A13 and the 11 welding of horizontal muscle roof beam, elevating platform 1 arranges in the square frame and slides with four angle steel A13 cooperations, elevating gear mounting panel 12 is fixed in the square frame, elevating platform 1's below, elevating gear 5 arranges in between elevating gear mounting panel 12 and the elevating platform 1.
Lift platform 1 includes upper mounting plate 8, bottom plate 10, angle steel B9, upper mounting plate 8 and bottom plate 10 are fixed respectively at four angle steel B9's upper and lower both ends, and four angle steel B9 of lift platform 1 slide with the cooperation of four angle steel A9 of frame slide and slide.
And a roller changing trolley hook head 7 is also fixed at one end of the base 4.
The base is provided with 4 wheels 14 and 2 roller-changing trolley hook heads 7 which can be matched with the working roller-changing trolley to realize the movement in the horizontal direction.
Fixed platform 3 is welded structure spare, by angle steel A13, channel-section steel and steel sheet welding, the frame slide of both sides respectively has the stand that 4 angle steel A13 are constituteed, and inside formation supplies lift platform 1 guide space that reciprocates, and stand lower part third department welding elevating gear mounting panel 12 is as elevating gear 5's support bottom surface, welds horizontal muscle roof beam 11 as the strengthening rib between 4 angle steel A13 on the stand. A connecting frame 6 welded by channel steel combination is welded between the two frame slideways, and the manual operating platform 2 is welded at the upper end of the connecting frame welded by the channel steel combination on the uppermost layer by a steel plate to form a wide plane.
2 lifting platform 1: the 4 sides of each lifting platform 1 are formed by welding 4 angle steels B9, an upper platform 8 and a lower fixing plate 10, the sizes of the angle steels are in clearance fit with a guide space formed by a frame slideway, the angle steels are installed in the frame slideway, and when the lifting platform descends to the lowest position, the upper plane and the manual operation table 2 are at the same height.
