Abstract
The invention discloses a load ground rail structure. The load ground rail structure is characterized by being composed of suit combined spherical surface bolts arranged between two steel i-beams which are parallelly arranged, the combined spherical surface bolt comprises a bolt, a beveled washer, a plain washer and a nut, an end stress surface of the bolt is provided with a globular cambered surface, and one side of a bolt head is fixedly provided with an A stop pin; one end of the beveled washer is provided with a hillslope, the other end of the beveled washer is provided with a gasket of a circular conical surface, and one side of the beveled washer is fixedly provided with a B stop pin; and the combination spherical surface bolt is arranged in a gap between two steel i-beam upper airfoil surfaces, and a test workpiece is placed between the upper airfoil surface of each steel i-beam and the plain washer and is fixed by the nuts. Compared with the prior art, the load ground rail structure provided by the invention has the advantages of simple structure and stable stressing characteristic, the flatness and parallelization are convenient to adjust, the structure has high precision, short construction cycle, and is safe and reliable; and the flatness less than 2mm can be realized, the parallelization is in a length range within 10 m deviates less than or equal to 1.5 mm, and the fabrication cost of a bearing strength platform is greatly reduced.
Description
Technical field
The present invention relates to the steel structure technical field of machinery, specifically a kind of load ground rail structure that is used for load test or test platform.
Background technique
At present, being used for test room's mechanical test or workshop product test run etc. has the test of certain required precision or the load ground of test platform, generally all adopts the load ground rail that is provided with the T-shape groove; Generally in 3.5m, the order price of overlength ground rail is just than higher for T-shape trough rail, its order length; As with round steel or the blank that is swaged into round steel; The T-shape trough rail of machine shaping, its stock utilization has only 25%, and waste is greatly.When some larger-size load grounds of design; Because length direction will use more T-shape trough rail to form, the load ground is in building course, and the planeness of ground load-carrying surface has suitable difficulty with the parallelism adjustment that is adjacent to rail; Precision is difficult to guarantee, and long construction period.
Summary of the invention
A kind of load ground rail structure that the objective of the invention is to be directed against the deficiency of existing technology and design, its adopts hot rolling steel I-beam and combinatorial sphere bolt to constitute load ground rail, and the planeness of ground load-carrying surface is adjusted all very convenient with the parallelism that is adjacent to rail; Realize that planeness is in 2mm; Parallelism is in the 10m length range between the adjacent load steel I-beam ground rail, deviation can be controlled in≤1.5mm in, reduce the expenditure of construction of load platform greatly; And precision is high, short construction period.
The objective of the invention is to realize like this: a kind of load ground rail structure; Be characterized in that this ground rail structure is made up of suit combinatorial sphere bolt between two steel I-beams that laterally arrange; The combinatorial sphere bolt is made up of bolt, beveled washer, plain washer and nut; The end stress surface of bolt is provided with spherical cambered surface, and the first side of its bolt is fixed with the A backing pin; It is domatic that beveled washer is that an end is provided with, and the other end is provided with the pad of conical surface, and beveled washer one side is fixed with the B backing pin; Be provided with gusset between two steel I-beams that laterally arrange; Gusset and steel I-beam are welding; The combinatorial sphere bolt sleeve is contained in the slit between the two steel I-beam top airfoils, and beveled washer and plain washer are separately positioned on the top airfoil both sides of steel I-beam, and the domatic and steel I-beam inner airfoil surface of beveled washer cooperates; The conical surface of beveled washer cooperates with the spherical cambered surface of bolt, and is fastening by nut after the placement test piece between the top airfoil of steel I-beam and the plain washer.
The said domatic gradient is identical with the gradient of steel I-beam inner airfoil surface.
Said gusset is equidistant being arranged between two steel I-beams.
The present invention compared with prior art has simple in structure, and mechanical characteristic is stable, and is safe and reliable; Planeness and parallelism are easy to adjust; And precision is high, and short construction period realizes that planeness is in 2mm; Parallelism is deviation≤1.5mm in the 10m length range, reduces the expenditure of construction of load platform greatly.
