In the band steel was produced, six-high cluster mill had obtained using widely.The intermediate calender rolls 11 of six-high cluster mill need be made axial float, so dispose the roll shifting device of play hydraulic cylinder I2 and play hydraulic cylinder II10 driving.As shown in Figure 1, the roll shifting device of extensive use at present is horizontally set on the rolling-mill housing play hydraulic cylinder to drive the roll shifting frame, and roll shifting hook 7 is housed on the roll shifting frame, hooks intermediate calender rolls 11 1 play in the chute in the rolling-mill housing window that coexists.Its roll shifting mount structure has following characteristics: 1 fen both sides of roll shifting beam by framework window, be connected into a door-shaped frame by the roll shifting frame with voussoir 3, bolt 4 and screw 5, and interface has certain rigid and non-adjustable.Because of the draw bail between roll shifting beam 1 and roll shifting crossbearer is hook-shaped, require the roll shifting frame to disintegrate and to assemble.The roll shifting frame is formed by the both wings that linking arm 6 usefulness bolts, flat key connect crossbeam 8 and hook seat crossbeam 25, and one of roll shifting hook 7 usefulness open and close hydraulic cylinder 9 and open and close.
Because traditional roll shifting frame is assembled by a plurality of parts, thereby it is high to the dimensional tolerance and the Geometrical Tolerance Principle of part processing, otherwise the assembling back is because of the depth of parallelism and the spacing precision deficiency of two roll shifting beams 1, easily suppress strength and produce jam with the chute in two framework windows, the jam phenomenon repeatedly appearred in domestic steel rolling mill.Therefore, be necessary technical scheme of the prior art is done further improvement, to remedy defective of the prior art.
Summary of the invention
The purpose of this utility model is at the problems referred to above, the roller mill intermediate roll shifting device that provides the depth of parallelism that a kind of structure was provided with rationally, improved two roll shifting beams and spacing precision to avoid jam.
For achieving the above object, the technical solution of the utility model is as follows: roller mill intermediate roll shifting device, comprise the roll shifting frame that is connected with the roll shifting beam, be equipped with on the roll shifting frame and can hook the coexist roll shifting hook of play in the chute of framework window of roll one, roll shifting frame both sides are arranged with the play hydraulic cylinder that drives the action of roll shifting frame, it is characterized in that the roll shifting frame is that overall structure and both wings are connected on the roll shifting beam by connecting flange and adjusting flange respectively.
Described connecting flange is a split-type structural, is respectively equipped with flat key between connecting flange and roll shifting frame, the roll shifting beam and positions with alignment pin and be connected with bolt.
Described adjusting flange is a split-type structural, has convexity; The level that is provided with is regulated double-screw bolt, and flange connects with fastening bolt.
The flange of described roll shifting frame both sides and connecting flange and adjusting flange connecting place has tongue-and-groove structure, in order to bear vertical force.
The convexity of described adjusting flange is 0.2 to 2 millimeter.
Regulate the puller bolt that flange also is provided with band back of the body nut.
The beneficial effects of the utility model:
1, the roll shifting frame is designed to an integral body, and simplified structure is convenient to processing;
2, the interface with roll shifting beam and roll shifting frame is designed to the face-flange formula, can conveniently adjust the depth of parallelism and the spacing of two roll shifting beams and also conveniently process to avoid the roll shifting jam;
3, connecting flange is split type, and the roll shifting beam end is easy to process.

The specific embodiment
In conjunction with the accompanying drawings the utility model is described further with specific embodiment below, referring to Fig. 2 to 5:
For fear of the influence of mismachining tolerance to the depth of parallelism and the spacing precision of two roll shifting beams, reduce the jam probability, the utility model is achieved by the following scheme: a kind of six-high cluster mill intermediate roll shifting device, comprise the roll shifting frame 15 that is connected with roll shifting beam 1, roll shifting hook 7 is housed on the roll shifting frame 15, roll shifting hook 7 can hook intermediate calender rolls 11 1 and coexist and do axial float in the chute in the rolling-mill housing window, and the power resources of play are located at the hydraulic cylinder (2,10) of roll shifting frame 15 both sides in branch.Be convenient to processing for simplified structure, roll shifting frame 15 is a U type overall structure.For the ease of the roll shifting hook of packing into, big apart from the terminal spacing of roll than traditional type at roll shifting frame 15.The both wings of roll shifting frame 15 are connected on the roll shifting beam 1 by connecting flange 12 and adjusting flange 16 respectively, and connecting flange 12 had both played the effect that is connected roll shifting beam 1 and roll shifting frame 15, the depth of parallelism and the spacing that can also regulate two roll shifting beams 1 with adjusting flange 16.
For ease of processing roll shifting beam 1 end, connecting flange 12 is a split-type structural.Because the weight of roll shifting frame 15 is bigger, so roll shifting frame both wings are provided with band tongue and groove flange 23, one group of fastening bolt I14 connects with connecting flange 12 usefulness, and the flange of tongue-and-groove structure can bear bigger vertical
Power.Being provided with flat key 13 between connecting flange 12 and the roll shifting beam 1 positions with alignment pin 22 and is connected with screw 24; Being provided with flat key 13 between the band tongue and groove flange 23 of connecting flange 12 and roll shifting frame 15 positions and is connected with bolt 14.
Described adjusting flange 16 is a split-type structural, and is provided with flat key 13 between the roll shifting beam 1 and positions with alignment pin 22 and be connected with screw 24; For the adjustable parallel degree, be set to have convexity and be provided with level adjusting double-screw bolt 20, the rotation level is regulated the spacing between double-screw bolt 20 fine-tuning two roll shifting beams 1.The convexity of flange be 0.2 to 2 millimeter preferable, can't play the effect of regulating the depth of parallelism too for a short time, too greatly then can influence degree of regulation.Outside two flanges connect with one group of fastening bolt II17, the puller bolt 19 of band back of the body nut 18 also can be set, can regulate the depth of parallelism though go up next group fastening bolt, use the puller bolt 19 of band back of the body nut 18 can increase the area that contacts between flange, to increase joint stiffness.
Above disclose only for preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
