Abstract

Disclosed is a supporting leg screw. The utility model is characterized in that a regulating sleeve is arranged between the part of the supporting leg screw and the bottom hole of equipment, and the part of the supporting leg screw is higher than the foundation; the upper end of the regulating sleeve is matched with a regulating cap; the part of the supporting leg screw, which is buried in the foundation, is sheathed with a supporting leg sleeve which is composed of supporting blocks, a sleeve pipe, a rib rod, etc; the lower end of the regulating sleeve and the root of the supporting leg screw are respectively connected with an upper supporting block and a lower supporting block. When the utility model is used for adjusting the level of the equipment, oblique iron is omitted. The utility model which has the advantages of quick and convenient adjustment and has the advantages of improving the stress condition of the supporting leg screw, and conveniently changing the supporting leg screw is especially suitable for installing large scale equipment.

Description

The utility model relates to a kind of foot screw.
The foot screw that fixed equipment is used generally is that root jag, head tighten up with nut, packing ring but adjust equipment level and need use wedge in addition, adjusts very inconveniently, and in addition, foot screw is easily crooked owing to pushed by foundation material, influences equipment installment quality.Moreover when ground requirement chin-deep, foot screw is very long, and its stress shape state is degenerated, and it also is pretty troublesome replacing foot screw.
The utility model purpose provides a kind ofly can adjust equipment level rapidly, and can improve stress phase, the foot screw that improves equipment installment quality and be convenient to change.
The purpose of this utility model is achieved in that foot screw is provided with one between the bottom outlet of base portion part and equipment above Ground adjusts cover, and its upper end cover is furnished with the adjusting cap; The part that foot screw is embedded in the ground is with the lower margin sleeve, and it is connected to form from top to bottom successively by upper support piece, sleeve pipe, lower support piece, muscle bar; Upper support piece middle part is threaded with adjusting the cover lower end, and the lower support piece is threaded with the foot screw root that passes adjustment cover and sleeve pipe mesopore.By described structure, can shorten foot screw length, improve the foot screw stress phase.The side of upper support piece also is fixed with vertical adjustment piece of band adjusting screw.Adjust the efficiency of equipment level state, its influence factor is a lot, is provided with one and vertically adjusts piece, cooperates the adjustment cover to adjust equipment level, gives the work rate that improves the adjustment equipment level, produces beyond thought special effect.If between bottom outlet that is added with cambered surface packing ring, equipment between adjustment cover and the equipment bottom surface and adjustment, be provided with, just can greatly alleviate of the influence of foot screw non-perpendicularity error to equipment installment quality to heart spare.
The utility model has been owing to saved wedge during erection unit, when making erection unit operation rapidly, convenient, installation quality guarantees easily.In addition, foot screw does not directly contact with foundation material, has prolonged foot screw working life, and changes more conveniently yet, is particularly suited for installing and using of main equipment.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
The foot screw 3 of erection unit 14 usefulness, it is provided with between bottom outlet of base section and equipment 14 above Ground and adjusts cover 8, its upper end cover is furnished with the cap 2 of adjusting, between overlapping, it and adjustment can turn the adjusting cap and can drive 8 risings of adjustment cover or decline with interior hexagonal, interior four jiaos or other similar wedging structure fit.The part that foot screw is embedded in the ground is with lower margin sleeve 16, and it has upper support piece 9, sleeve pipe 10, lower support piece 12, muscle bar 13 to connect to form successively from top to bottom, and Placement is removable or non-disconnectablely all can.8 lower ends are overlapped with being threaded with adjustment in upper support piece 9 middle parts, are fixed with vertical adjustment piece 6 in its side, establish adjusting screw 5 on it, jointly equipment are made horizontal adjustemt so that cooperate to adjust to overlap.Lower support piece 12 is adjusted cover and is connected with foot screw 3 roots of sleeve pipe mesopore with passing, and upper and lower anchor plate profile is square or polygonal, to bear moment of torsion.Muscle bar 13 quantity are at least two, according to actual needs, can adopt 3~4, even it is more, be fixed with anti-loose ring 11 at sleeve pipe 10 outer surfaces and muscle bar 13 suitable positions, to prevent the upper and lower play of foot screw, anti-loose ring 11 quantity are decided on concrete ground height.Be equipped with packing ring at equipment bottom outlet two ends, the upper end be a plain washer 15, and the lower end is promptly adjusted to overlap between 8 middle part bulge loops and equipment 14 bottom surfaces and is provided with cambered surface packing ring 7, contacts with cambered surface between bulge loop and the packing ring 7, with compensation foot screw skew error, it is reliable and stable that equipment is installed.For the nut one end non-perpendicularity that prevents foot screw overproof, can make sliding distribution structure with adjusting set upper side and bottom outlet, this example is for being provided with heart spare 14 at bottom outlet and adjustment inner room, it can be made into whole or split part, to guarantee equipment installment quality, turn flexibly for making to adjust to overlap, can after foot screw is poured into a mould foundation material, remove heart spare 14.

Claims (3)

1, a kind of foot screw that includes nut 1 and plain washer 15 is characterized in that being provided with between the bottom outlet of the base section above Ground of foot screw and equipment 14 and adjusts cover 8, and its upper end cover is furnished with the cap 2 of adjusting; Being embedded in of foot screw partly is with lower margin sleeve 16 in the ground, it is connected to form from top to bottom successively by upper support piece 9, sleeve pipe 10, lower support piece 12, muscle bar 13, upper support piece 9 middle parts are threaded with adjustment cover 8 lower ends, the side of upper support piece 9 is fixed with the vertical adjustment piece 6 that is provided with adjusting screw 5, lower support piece 12 is threaded with passing the foot screw root of adjusting cover and sleeve pipe mesopore, is fixed with anti-loose ring 11 at sleeve pipe 10 outer surfaces and muscle bar 13 suitable positions.
