The pulley guide loading device comprises a guide pulley seat, a pulley, a first actuating cylinder mounting seat, a horizontal loading actuating cylinder, an elastic screw sleeve and a steel wire rope, wherein the pulley is mounted in the guide pulley seat; the horizontal loading actuating cylinder is mounted in the first actuating cylinder mounting seat; one end of the steel wire rope is connected with a test piece; the other end of the steel wire rope is guided by the pulley and transmitted along the channel of the steel wire rope of the guide pulley seat to be connected to the horizontal loading actuating cylinder; one end of the elastic screw sleeve is connected to one end, which the steel wire rope does not pass through, of the guide pulley seat; and the other end of the elastic screw sleeve is fixed. The pulley guide loading device the vertical loading of the loading point, downwards near the ground, of the test piece into horizontal ground loading, so as to solve the problem the actuating cylinders cannot be mounted vertically because the loading point, downwards near the ground, of the test piece is near the ground, or the vertical load of the test cannot be applied because the reserved stroke of the piston rods of the actuating cylinders is insufficient after the actuating cylinders are vertically mounted.
Description
Technical field
The present invention relates to a kind of pulley guiding force-input device, particularly relate to a kind of pulley guiding force-input device for aircraft structure test.
Background technology
In aircraft structure test, choosing of test article support height is a major issue of testing in planning.Consider from Test item Load Characteristics and secure context, reduce sometimes the support height of test article.Support height can make the enforcement difficulty that test article part near the ground loads increase downwards and reduce test.Former because the downward loading Position of test article part near the ground apart from ground more closely cause pressurized strut can't vertical installation or vertical installation after the pressurized strut piston rod to reserve stroke inadequate, test load can't apply.
The pressurized strut of the downward load(ing) point of test article in the past all is mounted on the pressurized strut permanent seat, and the pressurized strut permanent seat utilizes holding-down bolt ground to fix, and no matter the less stroke pressurized strut of redesign processing from economy and test period, is all inappropriate.Design pressurized strut anchor fitting near the ground is replaced the pressurized strut permanent seat, by the ground setting height(from bottom) that reduces pressurized strut solve pressurized strut can't vertical installation or vertical installation after the pressurized strut piston rod reserve the inadequate problem of stroke.Yet pressurized strut anchor fitting near the ground still can't solve the vertical installation of pressurized strut fully or vertical installation primary piston bar is reserved the inadequate problem of stroke, and its practical application is restricted.
Summary of the invention
The objective of the invention is: a kind of pressurized strut pulley guiding force-input device is provided, converts force line to horizontal direction by vertical direction, make the pressurized strut Plumb load convert ground level to and load, solved the problem that test article downward point near the ground can't load.
technical scheme of the present invention is: a kind of pulley guiding force-input device, it comprises the leading sheave seat, pulley, the first pressurized strut mount pad, level loads pressurized strut, turnbuckle, steel rope, the second pressurized strut mount pad, wherein, pulley is arranged in the leading sheave seat, level loads pressurized strut and is arranged in the first pressurized strut mount pad, steel rope one end joint test spare, the other end prolongs leading sheave seat steel-cable channel and spreads out of after the pulley guiding, the level that is connected to loads in pressurized strut, described turnbuckle one end is connected to the unsanctioned end of leading sheave seat steel rope, the other end is fixed.
Described leading sheave seat and the first pressurized strut mount pad are arranged on the ground rail, and leading sheave seat length is greater than the ground rail spacing.
Described pressurized strut mount pad back-plane design becomes can block the boss form that base track prevents the vertically rail direction slip of pressurized strut mount pad.
Described bolt, swivel nut and right bolt three parts, wherein, the left and right bolt thread is respectively left-handed and dextrorotation, and swivel nut two ends tapped bore is respectively left-handed and dextrorotation.
Described swivel nut one end is fixed on the second pressurized strut mount pad through ears, and this second pressurized strut mount pad also is fixed on the ground rail.
Described loading pressurized strut piston rod end connects strong sensor.
Described pulley base top is provided with the pressure beam, and is locked by holding-down bolt.
Technique effect of the present invention is:
1) the pressurized strut Plumb load of realizing of force-input device simple and fast converts the ground level loading to but pulley leads, and has solved test article downward load(ing) point near the ground because pressurized strut can't vertical installation or the inadequate problem that causes test article to load of vertical installation primary piston bar reservation stroke.
2) utilize turnbuckle with the tension of the anti-loading direction of leading sheave seat, solved the horizontal slip problem of leading sheave seat in the guiding loading procedure, and turnbuckle can realize step-less adjustment, not limited by leading sheave seat installation site.
Pulley guiding force-input device successfully is applied among multinomial emphasis model test, erecting device simplicity of design, practicality, reliable, solved the aircraft structure test test article near the ground downward due to the Plumb load space not and problem that can't Plumb load has obtained expected effect.
Description of drawings
Fig. 1 is the structural representation of pulley guide piece.
The specific embodiment
See also Fig. 1, pulley of the present invention guiding force-input device comprises factory building ground rail 1, holding-down bolt 2, the first pressurized strut mount pad 3, bolt of rear end plate 4, pressurized strut 5, sensor 6, connects ears 7, tie bolt 8, steel rope 9, test article 10, leading sheave seat 11, pulley 12, pressure beam 13, pad 14, turnbuckle 15, fixedly ears 16, the second pressurized strut mount pad 17.Wherein, described pulley 12 utilizes tie bolt 8 to be arranged in leading sheave seat 11, pressurized strut 5 utilizes bolt of rear end plate 4 to be arranged on the first pressurized strut mount pad 3, steel rope 9 one end joint test spares 10, the other end prolongs leading sheave seat 11 steel-cable channels and passes after pulley 12 guiding, successively be connected in pressurized strut 5 by tie bolt 8, connection ears 7, sensor 6; Turnbuckle 15 1 ends utilize tie bolt 8 to be connected to the unsanctioned end of leading sheave seat 11 steel ropes, and the other end is fixed on fixedly on ears 16 by tie bolt 8 equally; Fixedly ears 16 are fixed on the second pressurized strut mount pad 17 by bolt of rear end plate 4.Leading sheave seat 11, the first pressurized strut mount pad 3 and the second pressurized strut mount pad 17 utilize holding-down bolt 2 to be arranged on ground rail 1.
When test loads, pressurized strut 5 tense wire rope 9 levels load, leading sheave seat 11 bears upward force and horizontal force, upward force balances each other with the application force of pressing beam 13, the anti-loading direction pulling force of horizontal force and turnbuckle 15 balances each other, and the first pressurized strut mount pad 3 and the second pressurized strut mount pad 17 back-plane design boss structures can prevent the vertically rail direction slip in process of the test of pressurized strut permanent seat.Process of the test middle pulley guiding force-input device is fricton-tight, the precision that warranty test loads.
Pulley guiding force-input device of the present invention has realized that test article downward load(ing) point Plumb load near the ground converts level ground to and loads, solved in aircraft structure test test article downward load(ing) point near the ground due to distance ground more closely cause pressurized strut can't vertical installation or vertical installation after the pressurized strut piston rod to reserve stroke inadequate, the problem that test load can't apply.
