Description
Technical field
The present invention relates to technical field of fastening, and in particular to a kind of to determine moment of torsion fixation shield formula foundation bolt.
Background technology
Foundation bolt is the pre-buried annex for solid mechanical equipment, during installation, and foundation bolt lower end is put into coagulation soil matrix
In the reserved hole of plinth, foundation bolt upper end passes through the mounting hole of plant equipment bottom, pre- in concrete foundation after plant equipment positioning
Stay secondary casting concrete in hole to fix foundation bolt, wait after secondary casting concrete solidification, adjusting pad is at plant equipment bottom
The height of the adjustment parallels in portion, makes the reference plane of plant equipment reach required required precision, finally tightens foundation bolt upper end
Nut, complete fixation to plant equipment.It is embedded in upper small greatly under the foundation bolt in the reserved hole of concrete foundation, tightens lower margin
During the nut of bolt upper end, foundation bolt will not be pulled out.In order to fix heavy duty, heavy duty equipment, shield is occurred in that on the market
Formula foundation bolt, wherein, " shield formula " word in shield formula foundation bolt is the heavy meaning, and it easily occurs in long-term use
The phenomenon for loosening and being broken, easily loses to heavy duty, the fixation of heavy duty equipment, so that can be to heavy duty, heavy duty equipment
Safety in production leave hidden danger.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind disclosure satisfy that high torsion
Square, the rigors of high intensity determine moment of torsion fixation shield formula foundation bolt.
The purpose of the present invention can be achieved through the following technical solutions：It is a kind of to determine moment of torsion fixation shield formula foundation bolt,
The foundation bolt includes upper sleeve pipe, setting of casing, the rectangular preiection being arranged between sleeve pipe and setting of casing and plugs and consolidate
The screw rod in sleeve pipe, setting of casing and rectangular preiection is scheduled on, the screw tip, which is provided with, determines torque cell and set for fixation
The second standby nut, it is described to determine torque cell and be arranged on below the second nut and fixed with screw rod, when equipment is installed, described second
Nut is moved down along screw rod, so as to secure the equipment on the concrete of bottom surface, when torque cell is determined in the contact of the second nut
After continue to move down, can to determine torque cell produce extruding, until determine torque cell damage, the second nut stop motion.If
Put and determine torque cell, be apparent that the second nut in fixing equipment, be screwed to which kind of degree can stop, pair will not both setting
It is standby to produce compressing damage, also because of the second nut loosening equipment will not be caused to leave hidden danger.
It is described to determine lower cover and upper cover plate of the torque cell including being sequentially sleeved at screw rod upper end from the bottom up, the lower cover
Plate includes horizonal base plate and vertical pipe sleeve, and the horizonal base plate and vertical pipe sleeve are set on screw rod and fixed with screw rod,
NOL ring is arranged on the outside of vertical pipe sleeve, when the second nut is moved down along screw rod, can be contacted with upper cover plate, and with
Upper cover plate extrusion stress ring, when NOL ring is destroyed, the second nut stop motion.Power needed for NOL ring fracture is fixed and can
Survey, when the second nut rotates and declines along screw rod, drive upper cover plate to push, NOL ring is under pressure, when pressure is being answered
When in the tolerance range of power ring, illustrate that the second nut is twisted tight not enough, until NOL ring destruction, the second nut stop motion,
It now both will not produce compressing to equipment to damage, and also because of the second nut loosening equipment will not be caused to leave hidden danger.
The upper cover plate is tool steel.Due to upper cover plate meeting extrusion stress ring, so having higher to its rigidity and hardness
It is required that.
The second described nut is located at the outside of upper sleeve pipe with torque cell is determined.
Cavity is provided with inside the rectangular preiection, and in cavity the first nut is set and rotated for preventing screw rod
Locking plate, first nut and locking plate are set on screw rod.
The cased bottom end closure.
The cased external diameter is more than the external diameter of upper sleeve pipe.The setting of lower pipe sleeve can cause whole foundation bolt and two
The cooperation of secondary casting concrete is more stable.
Compared with prior art, beneficial effects of the present invention are embodied in：Using a screw rod, it is socketed with outside screw rod
Pipe, sleeve pipe is connected by rectangular preiection and forms integral structure.Determine torquer and make it that the tools for bolts ' pretension torque value applied is accurate
Really.So so that the present invention has preferably fixing intensity in fixed heavy duty, heavy duty equipment, disclosure satisfy that height
Rigors of moment of torsion, high intensity, and higher reliability can be kept in long-term use, it is to avoid occur loosening and be broken
Phenomenon, it is ensured that heavy duty, the safety in production of heavy duty equipment.
