The invention belongs to the technology of airplane structure test loading, and particularly relates to a horizontal bearing steel frame column of a loading frame. The horizontal bearing steel frame column is strong in bearing capacity, good in stability and high in loading precision, and comprises two stand columns and a plurality of supporting rods. The stand column supporting rods comprise transverse supporting rods connected with the two stand columns transversely and oblique supporting rods connected with the two stand columns obliquely, the sections of the two stand columns are of a hollow 'double-H' structure, and column feet with U-shaped open type foundation bolt holes are arranged at the bottoms of the stand columns. The horizontal load applying problem can be effectively solved, especially the horizontal load at a high position. The horizontal bearing steel frame column can be connected and fixed with an airplane structure test plant ground rail conveniently, and is convenient to mount and dismount. A special joint is arranged on the steel frame column, the steel frame column can be connected with a frame system into a whole, and strength and stability are good. Universality is good, no loading blind area exists, and a secondary loading beam can be conveniently fixed.
Description
Technical field
The invention belongs to aircraft structure test loading technique, be specifically related to a kind of loading frame horizontal bearing steel frame columns.
Background technology
In aircraft structure test, need to load column and realize applying of aircraft horizontal load.Because aircraft volume is more and more huger, load is also very large, and loading system is had higher requirement, wherein there are many loading technique difficult problems to need to solve, as the problem that applies of aircraft horizontal load, use traditional cantilevered to load column and be difficult to meet the demands, there are following several point defects:
A) loading is highly higher, and column load-carrying capacity is more weak, very difficult realization of the large load applying of level of aircraft eminence.
B) the ground fixed form of column is easily slided, and needs before use to carry out a large amount of anti-skidding work.
C) ground injustice easily causes column generation deflection, and verticality of stand column cannot guarantee, causes column top load(ing) point error in mounting position larger.
Summary of the invention
The object of the invention is: the invention provides that a kind of load-carrying capacity is strong, good stability, horizontal bearing steel frame columns that loading accuracy is high.
Technical scheme of the present invention is: a kind of loading frame horizontal bearing steel frame columns, it comprises two columns, some struts, wherein, column strut comprises the singletree of two columns of horizontal connection and the hound of two columns of oblique connection, two " duplex " type structures that column cross section is hollow, bottom is the suspension column that is provided with U-shaped open type anchor (bolt) hole.
Described two column sides are provided with for the fixing strip shape of loading facilities and load hole.Suspension column bottom is provided with some reinforced ribs.
Technique effect of the present invention is:
1) can effectively solve horizontal load and apply problem, particularly the horizontal load of position higher position;
2) can be connected and fixed very easily easy accessibility with aircraft structure test factory building track;
3) in steel frame columns, there is special joint, can be linked as integral body with frame system, intensity, good stability;
4) commonality good, without loading blind area, fixedly secondary loading beam.
Therefore, horizontal bearing frame column of the present invention have advantages of easy to use, commonality good, be easy to Assembly &Disassembly, can bear larger horizontal load.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described further:
Please refer to Fig. 1,2,3,4, wherein:
Fig. 1 is the structural representation of loading frame horizontal bearing steel frame columns of the present invention.Described loading frame horizontal bearing steel frame columns comprises two columns and suspension column, some straight struts and hound.
1) column is " duplex " shaped steel, and column bottom is welded with center, the suspension column column edge of a wing and is shaped with strip shape hole, facilitates secondary to load the fixing of crossbeam; Junction, the web edge of a wing is welded with brace panel, improves antitorque, the curved ability of column.
2) straight strut and hound adopt finished product H shaped steel, for connecting two columns, play the effect that improves stability and transmit horizontal load;
3) by above-mentioned part weld together, and welded joint thereon, for being connected with other position of framework, final, make a horizontal bearing steel frame columns, for loading horizontal load.
Fig. 2 is loading frame horizontal bearing steel frame columns of the present invention and aircraft structure test drill shack track fixed form schematic diagram.The structure of this ground fixed form, includes 4 holding-down bolts, two tracks and 2 steel frame columns suspension columns.
1) on suspension column, there is U-shaped open type anchor (bolt) hole, can be fixed on ground by holding-down bolt; Suspension column and base plate are welded with reinforced rib, have increased stability and the compression capability of suspension column, also facilitate load diffusion earthward.
2) in aircraft structure test facility floor, being equipped with concave slot---track, is used for fixing various general establishing
3) holding-down bolt is used for connecting track and suspension column, and bolt bottom is imported in track and blocked, and top adopts backing plate, nut that suspension column is fixed in track.
Fig. 3 is the fixed form schematic diagram of loading frame horizontal bearing steel frame columns of the present invention and secondary beam.Fixed form is divided into and penetrates and do not penetrate steel frame columns two classes, when fixed form one exists blind area, can adopt mode two to fix, and sees Fig. 4.
1) cross section of steel frame columns is two " work " shapes, and the strip hole on its edge of a wing can penetrate holding-down bolt, is used for fixing secondary beam.
2) secondary beam is used for fixing loading facilities, and as hydraulic actuator, load is that the form by single supported beam passes in steel frame columns according to arm of force ratio on secondary beam.
Fig. 5 is the stressed schematic diagram of loading frame horizontal bearing steel frame columns of the present invention.Horizontal load, by column and the pole structure of horizontal bearing steel frame columns, has been delivered to ground.
1) because strut has transmitted most of horizontal load, column bear the traditional cantilevered column of bending moment ratio much smaller.
2) horizontal load by the pressure of suspension column, the bolt pulling force of lower margin spiral shell and the friction force of contact surface carry out balance, the good stability of total, load-carrying capacity is high.
In a word, loading frame horizontal bearing steel frame columns has solved the problem that applies of horizontal load, has the advantages such as easy to use, commonality good, be easy to Assembly &Disassembly, load-carrying capacity is strong, strength and stability is good simultaneously.
