Wherein, said tower leg plate comprises base plate and is welded in the angle steel on the plate top surface, and said billet is located between base plate and the tower leg basis, and the opposite end of said base plate is respectively equipped with an edge of a wing, offers the through hole that passes of confession stone bolt on the said base plate.
Wherein, the aperture of said through hole is not less than 1.5 times of stone bolt diameter.
Wherein, be provided with each billet that thickness does not wait and vertically superpose and arrange between the base plate of said tower leg plate and the tower leg basis.
Wherein, vertical line between said two edges of a wing and the depth of groove direction on the billet are perpendicular.
Wherein, the thickness on said two edges of a wing all base plate thickness with the tower leg plate is identical, and steel plate is adopted on the said edge of a wing.
Wherein, the width of said groove is not less than 1.5 times of stone bolt diameter.
The beneficial effect of the utility model is:
1) owing to has additional billet in this linkage; So when four tower leg bases of shaft tower produce differential settlement; Only need to realize adjustment to tower leg section height through simple operations; Make the base plate of tower leg plate be in level again, better guaranteed the stability and the safety of top shaft tower.In order to regulate the height of this shaft tower tower leg linkage more easily, also can be respectively equipped with an edge of a wing at the base plate opposite end of tower leg plate.
2) pass groove owing on billet, be provided with the confession stone bolt; So when four tower leg bases of shaft tower produce differential settlement; The base plate of regulating the tower leg plate through simple operations can be set up or change the billet of different-thickness as required, and through the groove on the billet billet plugged arbitrarily to level between the base plate of tower leg basis and tower leg plate; Simple in structure, easy to operate.

The specific embodiment
Below in conjunction with accompanying drawing the adjustment height type shaft tower tower leg linkage of the utility model is done further detailed explanation.
As shown in Figure 2; This adjustment height type shaft tower tower leg linkage mainly comprises tower leg basis 1, stone bolt 2 and billet 6; Through nut 4 and pad 5 the tower leg plate 3 of tower leg section is connected with stone bolt 2 on being embedded in tower leg basis 1; On the tower leg basis, be embedded with four stone bolt 2 in this example, billet 6 is between tower leg plate 3 and tower leg basis 1.
As shown in Figure 3; Tower leg plate 3 comprises base plate 31 and angle steel 32; Angle steel is welded in the upper end of base plate, offers and corresponding four through holes 9 that supply stone bolt to pass in four stone bolt positions 1.5 times of the aperture L >=stone bolt diameter of phi of this through hole on the base plate 31.In order to regulate the height of this shaft tower tower leg linkage more easily; Opposite end at base plate 31 respectively is provided with an edge of a wing 8; The thickness on two edges of a wing 8 is preferably identical with base plate 31 thickness of tower leg plate; Base plate 31 all adopts steel plate to process with the edge of a wing 8, and the edge of a wing and base plate adopt integral structure or split-type structural, that is: the edge of a wing can process the integral type steel plate, also can be fixedly connected a block plate respectively at the two ends of base plate 31 as the edge of a wing with base plate 31.
As shown in Figure 4, billet 6 be provided with supply stone bolt 2 to pass and with four corresponding two grooves 7 in stone bolt position, 1.5 times of the width W of each groove 7 >=stone bolt diameter of phi.
Billet 6 is between the mainboard 31 of tower leg basis 1 and tower leg plate, and the bottom of stone bolt 2 is embedded in the tower leg basis 1, the end face on tower leg basis is exposed on its top.After the groove 7 and the through hole 9 on the base plate 31 on the billet 6 passed at the top of stone bolt 2 successively, adopt nut 4, pad 5 and stone bolt 2 that column foot plate 3 and billet 6 are locked on the tower leg basis 1.The length that stone bolt 2 exposes tower leg basis end face should after nut is screwed, preferably keep leaving between stone bolt and the nut one section length in reserve greater than base plate 31 thickness, nut 4 thickness and the pad 5 thickness sums of billet 6 thickness, tower leg plate at least.Billet 6 between the base plate 31 of tower leg plate and tower leg basis 1 can be provided with the billet that one or more pieces thickness do not wait as required, when the multi-disc billet is set, each billet need vertically be formed by stacking.The shape of billet 6 base plate 31 shapes and size best with size and the tower leg plate adapt, and be when arranging, preferably that vertical line between two edges of a wing 8 and 7 depth directions of the groove on the billet is perpendicular.
The work and the Principles of Regulation of the utility model are as shown in Figure 5; When four tower leg bases 1 of shaft tower produce differential settlement; At first unclamp nut 4, on the edge of a wing of base plate 31 opposite ends a jack 10 is installed for 8 times respectively then, with the column foot plate jack-up of jack whole tower leg section; Perhaps extract the billet 6 of respective thickness out according to the differential settlement situation increase on four tower leg bases then; Finally make four tower legs be in same level, unclamp jack 10 then, locking nut 4 gets final product.Because billet is provided with groove 7, so when tower leg basis uniform settlement takes place, can regulate increase and decrease billet 6, the complicated processes of removing the dismounting integral bonding attachment from, handled easily through pluggable mode.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although the utility model has been carried out detailed explanation with reference to the foregoing description; Under the those of ordinary skill in field be to be understood that: still can make amendment or be equal to replacement the specific embodiment of the utility model; And do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the utility model.
