Patent document CN201768732U(prestressing force frame of rolling mill, 2011.03.23) propose that a kind of stiffness coefficient is high, lighter in weight and the low prestressing force frame of rolling mill of cost of manufacture, this frame adopts entablature, sill and two root posts composition, column makes hollow from solid, except saving material, when reality uses, pretightning force contrary when horizontal force when it bears rolling is converted into rolling, therefore, the rigid requirements of rolling mill can also be guaranteed.But when reality uses, because roll stand is mounted on foundation, in the operation of rolling, the strength and stiffness that the roll stand demand fulfillment same with the draw bail of rail chair is enough, this problem is not resolved in the prior art, and for this reason, the utility model arises at the historic moment.
Utility model content
The purpose of this utility model is to provide a kind of closed frame device being applicable to rolling mill, in the apparatus, frame and rail chair are directly fixed on foundation by pin, eliminate the set bolt between frame and rail chair, be convenient to I&M, meanwhile, between rail chair and foundation, adopt keeper to be fixed, effectively can adapt to the job specification of frame, and provide higher steadiness for frame.
The utility model is achieved through the following technical solutions: a kind of closed frame device being applicable to rolling mill, described closed frame device is primarily of frame, rail chair and foundation composition, the utility model overcomes prior art mid frame and adopts set bolt to carry out being connected the potential safety hazard that may exist with rail chair, propose following structure: in described frame, be provided with the through hole installed for pin, described frame and rail chair are fixed on foundation successively by pin, keeper is provided with between described rail chair and foundation, described foundation and rail chair are provided with the draw-in groove for keeper setting-in, in the utility model, frame and rail chair are directly fixed on foundation by pin, eliminate the set bolt between frame and rail chair, be convenient to I&M, when reality uses, because rail chair need bear weight and the tilting moment of frame and equipment, for this reason, the utility model adopts keeper to improve between rail chair with foundation and is fixedly connected with, and provide higher steadiness for frame, practical effect is good.
In the utility model, described keeper is the integrative-structure be made up of upper wedge and lower wedge, described upper wedge is flush-mounted in the draw-in groove with rail chair, described lower wedge is flush-mounted in the draw-in groove of foundation, in actual application, rail chair and foundation can complete the one-shot forming of draw-in groove in preparation process, install and keep in repair all very convenient.
For further improving the stability of pin, keeper is arranged at the fixture be sleeved on pin by the utility model, and described upper wedge and lower wedge are provided with installing hole, and described upper wedge and lower wedge are set on pin by installing hole.
For improving the service life of rail chair and foundation, reduction maintenance cost, the utility model described upper wedge and rail chair draw-in groove, be equipped with packing ring between lower wedge and the draw-in groove of foundation.
For further improving the steadiness of frame, in the utility model, the installing hole of the cross section of described pin, through hole, the installing hole of upper wedge, lower wedge is all in quadrilateral structure.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is reasonable in design, and frame and rail chair are directly fixed on foundation by pin, eliminate the set bolt between frame and rail chair, are convenient to the I&M of equipment.
(2) the utility model structure is simple, rail chair and foundation are fixed by keeper, keeper can effectively be flush-mounted between rail chair and foundation, can provide the weight and tilting moment of bearing frame and equipment, also for frame provides higher steadiness for rail chair.
(3) the utility model upper wedge and rail chair draw-in groove, be provided with packing ring between lower wedge and the draw-in groove of foundation, this structure can effectively prevent wedge, lower wedge and draw-in groove from causing damage to rail chair and foundation because of friction, has service life of equipment, reduces the advantage of maintenance cost.
(4) the utility model relate to pin cross section, through hole, the installing hole of upper wedge, lower wedge installing hole all in quadrilateral structure, this structure further can improve the steadiness of frame, and practical effect is good.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
Set bolt is adopted to carry out being connected the potential safety hazard that may exist for overcoming prior art mid frame and rail chair, the utility model proposes a kind of closed frame device being applicable to rolling mill, this device is primarily of frame 1, rail chair 2 and foundation 3 form, its structure difference with the prior art comprises following two aspects, one, because frame 1 is provided with the through hole installed for pin 4, therefore, frame 1 and rail chair 2 directly can be fixed on foundation 3 successively by pin 4, eliminate and set bolt is set between frame 1 and rail chair 2, be convenient to the I&M of equipment, on the other hand, owing to being provided with keeper between rail chair 2 and foundation 3, keeper is flush-mounted in the draw-in groove 5 on foundation 3 and rail chair 2 respectively, when reality uses, because rail chair 2 need bear weight and the tilting moment of frame 1 and equipment, therefore, arranging can effectively improve between rail chair 2 with foundation 3 and being fixedly connected with of keeper is adopted, and providing higher steadiness for frame 1, practical effect is good.
Structure is known as shown in Figure 1, the structure of the keeper that the present embodiment relates to can further be summarized as follows: in the present embodiment, keeper is the integrative-structure be made up of upper wedge 6 and lower wedge 7, upper wedge 6 is flush-mounted in the draw-in groove 5 with rail chair 2, lower wedge 7 is flush-mounted in the draw-in groove 5 of foundation 3, in actual application, keeper effectively can consolidate being fixedly connected between pin 4 pairs of rail chairs 2 and foundation 3, for convenience of installing, rail chair 2 and foundation 3 can complete the one-shot forming of draw-in groove 5 in preparation process, install and keep in repair all very convenient.For improving rail chair 2 and the service life of foundation 3, reduce maintenance cost, the present embodiment upper wedge 6 and rail chair 2 draw-in groove 5, be equipped with packing ring 8 between lower wedge 7 and the draw-in groove 5 of foundation 3.
Embodiment 2:
The present embodiment is from the difference of embodiment 1: the structure of the keeper that the present embodiment relates to and set-up mode different, as Fig. 2, shown in 3, in the present embodiment, upper wedge 6 and lower wedge 7 are equipped with installing hole, when mounted, upper wedge 6 and lower wedge 7 can be set on pin 4 by installing hole, can be used for the stability further improving pin 4, certainly, for further improving the steadiness of frame 1, in the present embodiment, the cross section of pin 4, through hole, the installing hole of upper wedge 6, the installing hole of lower wedge 7 is all arranged in quadrilateral structure, stability is stronger.
The utility model is reasonable in design, structure is simple, when reality uses, frame 1 and rail chair 2 are directly fixed on foundation 3 by pin 4, eliminate the set bolt between frame 1 and rail chair 2, be convenient to I&M, meanwhile, between rail chair 2 and foundation 3, adopt keeper to be fixed, effectively can adapt to the job specification of frame 1, and provide higher steadiness for frame 1, suitablely extensively to promote the use of.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, every any simple modification, equivalent variations done above embodiment according to technical spirit of the present utility model, all falls within protection domain of the present utility model.
