Lower end is weldingly fixed on anchor slab surface, and the center of square sleeve offers internal thread hole, and the lower section of adjusting screw rod is screw rod section,
The screw rod section screws in downwards in above-mentioned internal thread hole, and the upper end of adjusting screw rod forms an expanded letter portion.
The utility model discloses a kind of tower crane foundation levelness regulating devices, compared to the prior art, this tool
There is following technical effect:
(A) it is adjusted by high-strength bolt, ensure that the precision of base water Pingdu；
(B) steel construction load-bearing is relied on, and larger with bed course base surface, it is heavy to guarantee not generating under fixed supporting leg Gravitative Loads
Drop；
(C) this regulating device makes in warehouse in advance, and construction site can be used directly, and work efficiency significantly improves；
(D) derrick crane to same model is, it can be achieved that batch production.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model top view.
Fig. 3 is the utility model usage state diagram.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
The utility model discloses a kind of tower crane foundation levelness regulating devices to be different from as shown in fig. 1
The prior art is: the levelness regulating device includes the upper anchor slab 1 that upper and lower horizontal distribution has and lower anchor slab 2, upper 1 He of anchor slab
The gusset 3 that two panels is parallel to each other vertically is equipped between lower anchor slab 2, the upper limb of gusset 3 is fixedly welded and with upper anchor slab 1 perpendicular to upper
Anchor slab 1 is distributed, and the lower edge of gusset 3 and lower anchor slab 2 are fixedly welded and are distributed perpendicular to lower anchor slab 2, upper anchor slab 1 and lower anchor slab 2 it
Between be provided with right-angled intersection gusset 4, right-angled intersection gusset 4 is located between the gusset 3 of two sides, and the centre bit of upper anchor slab 1 is provided with
One square sleeve 8, the lower end of square sleeve 8 are weldingly fixed on 1 surface of anchor slab, and the center of square sleeve 8 offers interior spiral shell
The lower section of pit 5, adjusting screw rod 6 is screw rod section, which screws in downwards in above-mentioned internal thread hole 5, the upper end of adjusting screw rod 6
Form an expanded letter portion 7.
In the specific implementation, a hole for injecting glue is offered on the side wall of square sleeve 8, after adjusting screw rod 6 is adjusted in place
External injecting glue can be carried out, adjusting screw rod 6 and square sleeve 8 are fixed to each other, prevents adjusting screw rod 6 from welding with fixed supporting leg 9
It is displaced in the process
The present apparatus carries out levelness adjusting using high-strength bolt, and can ensure that the levelness of four fixed supporting legs is no more than allows
Value.
The present apparatus is welded into half box-structure using steel plate, can be within 1.0 tons of load-bearing, and the substance of fixed supporting leg is no more than
0.5 ton.
