Abstract

The utility model provides a baybolt device for installing mechanical equipment. The utility model which is composed of a center bolt, a spherical cushion, a regulating sleeve, a casing, a rotary core, and an anchor bar can be regulated at will in three-dimensional space. By using the utility model, the process of casting concrete for two times can be removed. The utility model which has the advantages of shortened construction period, reduced workload, and good effect on large equipment, heavy equipment, power equipment, and oscillation equipment, and has the advantages of conveniently and exactly regulating the levelness of the equipment, and firm and reliably installing the equipment can be used for installing various kinds of electromechanical equipment.

Description

Universal-regulating bay-bolt

The present invention relates to a kind of anchor bolt apparatus that machinery equipment is installed that is used for, it is a kind of can the adjustment arbitrarily at three dimensional space, can when Equipment Foundations are constructed, give earlier and burying underground, and can remove the final grouting operation from, shorten the equipment novel anchor bolt apparatus of installation period.

Now, the general method for embedding of the stone bolt that install machinery equipment is used is at first to carry out the once pouring on basis, and give and reserve the stone bolt hole, thereafter pass through secondary natural Health preservation concrete again, reach designing requirement after, also to carry out more loaded down with trivial details adjustment work in the lifting machinery equipment when in place.So in the whole erection process, placement of concrete will carry out secondary, the natural Health preservation concrete also needs secondary, and the adjustment of machinery equipment also needs secondary, has so just expended more human and material resources, and has taken long installation period.

The object of the present invention is to provide a kind of spiral lifting mechanism that carries, can quick, easy, accurately adjust the anchor bolt apparatus of machine levelness reliably.

The contrast accompanying drawing is given to describe in detail below.

Accompanying drawing 1 is the longitudinal sectional drawing of general structure of the present invention, has reflected the combined situation of whole parts of this device, and it is by centre bolt (1), nut (2), and ball ring (3) is adjusted cover (4), and housing (5) changes core (6) and dowel (7) and forms.

Accompanying drawing 2 is master, the plan view of centre bolt (1).

Accompanying drawing 3 is for changeing master, the plan view of core (6).

Accompanying drawing 4 plan view and its partial sectional view for adjusting cover (4).

Accompanying drawing 5 is the structure situation of housing (5).

As shown in Figure 2, the bolt head of centre bolt (1) is the isosceles trapezoid piece of an off-centre, and trapezoid block two waists are domatic to be cooperated with commentaries on classics core (6).The structure shape of changeing core (6) is a cone-shape (as shown in Figure 3), the lower end edge diametric(al) of cone is offered an isosceles dovetail groove, dovetail groove two inclined-planes cooperate with the trapezoidal head inclined-plane of centre bolt (1), dovetail groove is exceedingly high in diametric half length, centre bolt (1) can slippage in exceedingly high radius length, simultaneously, change core (6) and can do 360 ° revolution again.Centre bolt (1) is along the radial direction slippage, and it just can be adjusted arbitrarily in the central space of adjusting cover (4).Adjusting the upper-end surface of overlapping (4) (as shown in Figure 4) is spherical, matches with ball ring (3), and end periphery is an outer-hexagonal shape on it, and this is wrench adjustment place.Garden week is a flank of thread outside its lower end, and the place is provided with subtriangular circular groove in the flank of thread lower middle, and upwards mills out 6 elongated slots from the underpart.The inner hole surface of lower end is the interior garden conical surface, and this garden conical surface matches with the outer garden conical surface that changes core (6).Adjust the big 20-30 millimeter of diameter of the interior boring ratio centre bolt (1) of cover (4), this redundant space is the free adjustment amount of centre bolt (1) in horizontal plane just.The outside thread face of adjusting cover (4) matches with the inner threaded surface of housing (5).Housing (5) is the thread bush of a sealing on the housing as shown in Figure 5, and it matches with the outside thread face of adjusting cover (4), and its lower end is 3～4 dowels (7) that increase anchor force.

When using universal adjustment stone bolt, before the base concrete pouring, it is good earlier bolt housing (5) to be pressed the plan fixed size.Should guarantee housing central position error in the time of fixedly in 6 millimeters of φ, the horizontal gradient error on plane is in 0.5/150 on the housing.After the housing fixation, get final product placement of concrete, concrete once waters and puts in place, vibration compacting, floating, press polish, health.After treating concrete setting, clean housing (5) inner chamber earlier, and other part is also cleaned up, and smear a little machine oil or drier oil at the screw thread place.When the assembling stone bolt, earlier centre bolt (1) is put into housing (5) inner chamber, and note making bolt M place (as shown in accompanying drawing 2) be close to shell body wall, put into then and change core (6), and make centre bolt (1) slippage to the center, then screw in again and adjust cover (4), after adjusting cover (4) and screwing, fall to twist two circles again, continue after, put ball ring (3), at this moment can lift machinery equipment.After the equipment handling causes the stone bolt sky, slowly land, when the equipment bottom surface when bolt top reaches the 10-20 millimeter, stop landing equipment.When equipment bottom outlet axial line distance is big (greater than 5 millimeters), should command crane crawl translation device as bolt axis at this moment, two axial lines is drawn close as far as possible.When most of bolt axis and machine bed plate axially bored line are approximately consistent, should stop mobile crane, just can adjust centre bolt (1) this moment, makes it aim at the machine bottom plate hole.Then, the slowly land machine, directly cause land in place.At last, adjust the work of machine levelness.According to the machine construction feature, at first around the machine center position, select three place's stone bolt of triangle position to be the adjustment benchmark, and then unscrew the adjustment cover of all the other all stone bolt, its ball ring and machine bottom surface are broken away from.Like this, entire machine just only is bearing on the ball ring of three place's benchmark bolts.At this moment the available horizontal instrument is measured the levelness of machine, and adjusts cover (4) by rotation simultaneously and adjust the machine levelness, directly causes the machine levelness and reaches till the designing requirement.Tighten earlier the nut of three benchmark bolts temporarily, and with machine levelness of leveling instrument check no change is arranged, as change and should adjust a little, as no change, promptly adjust cover and nut from equipment center to tightening each successively all around, the degree of tightening should be controlled unanimity.At this moment, machinery equipment is promptly accused and is installed.Just can connect power supply subsequently, can go into operation.

From above-mentioned whole erection process as can be seen, use universal adjustment stone bolt erection unit, simple to operate, need not the final grouting concrete, save the duration, and it is fast and simple to adjust the machine levelness, accurately reliable.

Claims

A kind of device that is used to install and adjust machinery equipment.It is characterized in that having centre bolt (1) with eccentric trapezoidal head, the commentaries on classics core (6) of combination with it, the male cone (strobilus masculinus) that changes core (6) cooperates with the inner conical surface of adjusting cover (4) lower end, dovetail groove two inclined-planes that change core (6) cooperate with the trapezoidal head bi-side of centre bolt (1), adjust circular groove and longitudinal opening groove that cover (4) lower end is provided with a necking down, housing (5) lower end is provided with dowel (7).
