Background technology
The wind tunnel force measurement test is the research means of carrying out the research of building structure wind resistance; Force balance is a visual plant of carrying out the wind tunnel force measurement test; In the wind tunnel force measurement test, building model is installed on the force balance; Balance is experienced the suffered wind-force of the building model line item of going forward side by side; Balance installs that levelness is not high in practical application, balance orthogonal component direction has drift angle etc. all to influence accuracy of experimental results with coming flow path direction, simultaneously because model installation site and highly different need the various supports body to be used to install balance.Regrettably the domestic majority wind-tunnel does not all have a cover can adapt to the device that various situation also can accurately be adjusted day flat bed more neatly at present, can only change bracing or strutting arrangement according to test situation, causes the efficient of serious waste and influence test.
Summary of the invention
The purpose of the utility model is to provide a kind of wind tunnel force measurement balance multifunctional supporter, it can be used in the different position of turntable force balance is installed rapidly and accurately, thereby lay the foundation for carrying out the Wind Engineering dynamometer check.
The utility model solves the technical scheme that its technical matters adopted:
The rectangular steel plates of the utility model is horizontally fixed on the wind-tunnel turntable; Circular steel plate is placed on the rectangular steel plates upper surface; Have three sections deep-slotted chip breakers of five equilibrium on the same circumference at circular steel plate center, be fixed on rectangular steel plates on five equilibrium arrange that the deep-slotted chip breaker that three small screws pass respectively separately fixes circular steel plate and rectangular steel plates with nut; Five equilibrium is fixed with three big screw rods on the same circumference at circular steel plate upper surface center; Difference install adjustment nut on three big screw rods; The equilateral triangle steel plate is placed on three setting nuts after passing big screw rod; And with gland nut the triangle steel plate is pressed on the setting nut respectively, equilateral triangle steel plate middle part has the screw that a plurality of installation force balances are used.
The axle center of described circular steel plate, equilateral triangle steel plate and force balance is positioned on the same pedal line.
The beneficial effect of the utility model is:
The utility model can be according to the balance installation site, and balance orthogonal component direction and the angle that comes flow path direction, the levelness that can regulate the balance base for supporting can be regulated in the position of adjustment balance base for supporting.This device can improve balance installation accuracy and installation effectiveness greatly.
