Abstract
Disclosed is a connecting rod type anchor bolt. The connecting rod type anchor bolt comprises a bolt, a ground anchor seat, a sleeve seat and a screw cap. The screw cap is connected with a thread part penetrating the ground anchor seat and the bolt of the sleeve seat in a screw mode. The structure of the connecting rod type anchor bolt is characterized in that an elastic component is further arranged between the ground anchor seat and the sleeve seat on the bolt in a sleeved mode. A connecting rod mechanism composed by a movable pulling rod and a middle connecting rod is connected between the ground anchor seat and the sleeve seat. A position of the sleeve seat on the bolt is changed by revolving the screw cap, thus a relative position of the ground anchor seat is changed. A putting and closing or a stretching position of the movable pulling rod and the middle connecting rod connected between the ground anchor seat and the sleeve seat is changed synchronously and adjusted, thus a foundation bolt with adjustable tensile ability is formed. The connecting rod type anchor bolt is used as the foundation bolt when the connecting rod type anchor bolt is embedded in the foundation base with a watering fixing way after the scheduled tensile ability is achieved when a user adjusts according to a practical service condition. The connecting rod type anchor bolt can be fixedly placed on the foundation base providing for light or heavy mechanical equipment of different standards.
Description
Technical field
The present invention relates to a kind of link type crab-bolt, be espespecially a kind ofly exclusively used in the link type foot bolt actively machinery be fixed on foundation.
Background technique
As shown in Figure 1, the stone bolt 10 be commonly called as is exclusively used in the link be fixed on by the base of machinery 80 on foundation 90.
The prior art structure of this stone bolt 10, is made up of with externally threaded screw rod 12 two-part a head 11 and.The head more than 11 of this stone bolt 10 is made the shape of jag formula and buckle; and mat strong concrete 95 is by buried for head 11 and water solid among foundation 90; allow the screw rod 12 of this stone bolt 10 stretch out exposed parts from foundation 90 simultaneously; settle to be supplied to machinery 80; use by using lock nut 15 machinery 80 to be fastened on foundation 90, to guarantee precision and the life-span of machinery 80 again.
In other words, stone bolt 10 need the head 11 of its jag formula of mat or buckle really buried enter foundation 90 reach certain depth, just possess and be unlikely to effect that is destroyed and that be pulled out occurs, therefore user needs the parameters such as light, the heavy and impact shock of the load according to machinery 80 is strong, weak to determine and the selectively length of foot bolt 10 and diameter specifications.
Such as, when settling the light-duty machinery equipment 80 that dynamic load is comparatively light, impact shock is compared with weak tendency, it is excessively dark that the head 11 of stone bolt 10 need not imbed foundation 90, the short stone bolt 10 only length specification need being selected shorter, and when settling the heavy duty equipment 80 that dynamic load is heavier, impact shock is stronger, the head 11 of stone bolt 10 must be imbedded foundation 90 and reach certain depth, must select the elongated stone bolt 10 that length specification is longer and diameter specifications is thicker.
But, too many stone bolt 10 of planting different size is had in prior art, even if the parameters such as the load of user's foundation machinery 80 and impact shock still not easily select the most applicable stone bolt 10, and, the structure of stone bolt 10 was not often innovated for a long time again, and industry is there's no one who doesn't or isn't expected to invent or improved.
