In above two kinds of syndetons, the first is only applicable to light duty compressor, and bearing load is less.
The second is applicable to big-and-middle-sized compressor, but because there is the cavity of a plurality of openings the below, basis, causes underlying strength bad; Secondly, what this structure adopted is that hydraulic pre-tightening connects, larger to space requirement, thereby causes compressor arrangement and weight to increase, and brings very large trouble to design, and cost has also increased many.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of reciprocating compressor ground feet connecting structure, and it adopts breakaway nut shield formula ground feet connecting structure, and underlying strength is high, easily dismounting.
The purpose of this utility model is achieved in that the overground part of studs is that upper stud passes gas compressor with reciprocating lower margin hole and pad successively, is screwed into upper stud with the nut of jackscrew, and jackscrew is tightened; Section is criss-cross protective cover and places undergroundly, and the under ground portion of studs namely descends double-screw bolt to place in the vertical chamber of protective cover, and square nut screws in lower double-screw bolt and also places in the protective cover horizontal cavity.
Job practices is 1) first the lower double-screw bolt with studs be screwed on the square nut, Combination Welding protective cover then simultaneously, is put into protective cover to the composite member that square nut and studs form; 2) then according to the ground placement of foot put successively fix the composite member that is formed by protective cover, square nut and studs after, grouting is first time carried out on the basis, is in the milk highly and protective cover top one flat getting final product; 3) after the basic first time, grouting was solidified, put the sand block piece at each protective cover upper opening place; 4) then compressor is winched to again each sand block piece top, and allow each studs pass the lower margin hole of compressor; 5) after compressor level and Height Adjustment are good, the grouting second time is carried out on the basis; 6) after the basic second time, grouting was solidified, the composite member of square nut, jackscrew and pad composition is screwed to the upper stud of studs, tighten symmetrically and evenly each jackscrew according to the moment intersection that calculates at last and get final product.
Compared with prior art, good effect of the present utility model is:
1) easy accessibility, quick.During installation, tighten each jackscrew with a torque spanner intersection symmetry and get final product; During dismounting, after first the adjacent jackscrew of a certain jackscrew both sides being tightened slightly, just can back out easily this jackscrew.
2) stressed evenly with the nut centre bore screw thread of jackscrew, application life is longer.There is certain distance between the top wire hole that this nut week makes a circle and the major thread hole at breakaway nut center, marquis when symmetrical chiasma is tightened each jackscrew, this distance has just become the arm of force, therefore, each jackscrew has just formed moment in this nut center relatively, so that small elastic deformation occurs this nut, this distortion is useful, its Effective Raise the contact tooth number of this nut screwed hole of centre screw thread so that this nut center screw thread is stressed more even, prolonged application life.
3) syndeton that forms with the nut of jackscrew, jackscrew and pad does not need very large space during operation, and pretightning force control is also comparatively accurate.
4) studs in this structure owing to not buried extremely by the basis, so the elasticity of studs has obtained larger release, during pre-stressed joint, can be accomplished the elasticity pretension, possesses very high reliability.
5) square nut in this structure can move along horizontal four direction in protective cover, can realize studs adjustment in the horizontal direction.
6) because basic internal does not have unlimited cavity, and foundation structure is durable, so that the basis has enough intensity to bear external applied load.
