Description
Technical field
The present invention is directed to the anti-skidding problem of loading column that vertical track direction is installed in aircaft configuration ground intensity slow test; design one loads column non-slip device; it is mainly used in preventing loading column to occur and slide between ground causing that test stability reduces in test loading procedure, or the problem that the overproof protection test of Loading Control System surprisingly stops.
Background technology
In test loading procedure, the accident owing to loading column is slided and is caused that loading equipemtn deviates original design coordinate position, thus affecting test loading accuracy, and then affects test data accuracy；When test load is bigger, loading column slides suddenly and may result in the overproof protection of Loading Control equipment, and test is unexpected to be stopped.Carrying in process of the test at height, stopping once occur that test is unexpected, it is likely that cause the accidental injury of testpieces, ultimately cause test incident.Above-mentioned fortuitous event will affect model test mission progress, simultaneously potential empirical risk.In aircraft structure strength slow test designs, often according to conventional load(ing) point installation experience, the main frictional force adopting the pressure common apparatus such as beam, foundation bolt to increase column and ground, and utilize the equipment such as pressurized strut base, top ferrum to coordinate to install non-skid feature according to locus, testing ground, the possible glide direction of column carries out displacement constraint, it is achieved the ground loading column is anti-skidding.Conventional anti-skidding scheme usually limits according to load(ing) point magnitude of load and field ground space in testing ground and formulates feasible anti-skidding scheme, these schemes are built upon greatly on empirical basis, there is randomness and uncertainty, it is not reaching to the purpose designed in advance, too increases substantial amounts of on-the-spot repeated workload simultaneously.
It is anti-skidding that ground implemented by the loading column that vertical track is mainly installed by the present invention, has certain length regulating power, by length adjustment, coordinates general changeover portion, is suitable for arbitrarily loading the skid-resistance requirements of uprights vertical track installation site.This invention device is installed simple, it is possible to is effectively prevented the loading column slip that vertical track is installed, and reduces loading column non-skid feature installation workload, can play time saving and energy saving positive role.
Summary of the invention
The present invention seeks to utilize this device, effectively prevent the loading column that vertical track is installed from occurring along ground accident sliding problem in test loading procedure.During use, this device is installed to corresponding track, the loading column bottom that needs are anti-skidding is fixed by regulating length, or by connecting with general changeover portion, regulate bottom length vertical columns again, reach column can slidable to retrain along loading direction, thus guarantee test loads stability, it is ensured that test loading procedure is smoothed out.
The invention provides a kind of for the spacing anti-skidding device of column, it is characterized in that, including supporting base (1), regulating screw mandrel (2) and anti-skidding top board (3), regulate screw mandrel one end through supporting base and being installed vertically on support base end face by screw thread, regulate that the screw mandrel other end is vertical with the rear end face of anti-skidding top board is rotatably connected, the front end face of anti-skidding top board is for fitting with column, and the lower surface of anti-skidding top board and ground fit.Regulate screw mandrel and withstand anti-skidding top board, anti-skidding top board (3) support post, by regulate screw mandrel in supporting base (1) screwed hole precession, thus the level that realizes pulls anti-skidding top board (3), regulate the supporting role of column.
Further, support that base includes the fixed part (1-1) of lower section and the installation portion (1-2) of top, step surface (1-3) is formed between fixed part and installation portion, fixed part is fixed in track, regulating screw mandrel one end and be installed vertically on support floor installation end surface by screw thread, step surface and anti-skidding top board lower surface are in same plane.It is in same plane, it is ensured that regulate screw mandrel (2) parallel with ground by step surface and anti-skidding top board lower surface.
Further, anti-skidding top board includes block (3-1) and annular screens groove (3-2), block is positioned at the front portion of anti-skidding top board, block front end face is for fitting with column, annular screens groove is positioned at the rear end face of anti-skidding top board, regulating screw mandrel and include end annular flange flange (2-1), end annular flange flange is stuck in annular screens groove, regulates screw mandrel (2-2) and realizes being rotatably connected by end annular flange flange and annular screens groove with anti-skidding top board.The rotation regulating screw mandrel (2) can be converted into moving horizontally of block (3-1) by end annular flange flange and annular screens groove.
Further, support to have through hole on base (1), by through hole, foundation bolt (4) will support that base (1) and track are fixed.
Further, regulate screw mandrel (2) and be provided with rocking bar (6) through the part supporting base.
Wherein support that base is fixed in track with two foundation bolts, make anti-skidding top board closely prop up loading column bottom (general changeover portion can be installed additional at anti-slip top front edge of board if desired, transition section length is less than 1000mm) by regulating screw mandrel.This shoe maximum skid resistance 40 tons (safety coefficient f=4), the loading column that can efficiently vertical track direction be installed plays the anti-skidding effect in ground, improves test loading procedure stability.
(1) have the advantage that and good effect
This shoe has the following advantages
Increase the loading column stability in loading procedure that vertical track is installed；
Regulate wire rod thread and there is self-locking performance, it is ensured that initial mounting state is stable；
Adapt to any installation site ground of loading column skid-resistance requirements of vertical track；
The vertical track installation loading anti-skidding scheme of column can be realized design in advance；
Installing/dismounting is simple and convenient, can by people's complete independently.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the installment state schematic diagram of the present invention.
Detailed description of the invention
Referring to accompanying drawing 1 and Fig. 2, the invention provides a kind of for the spacing anti-skidding device of column, it is characterized in that, including supporting base 1, regulating screw mandrel 2 and anti-skidding top board 3, regulate screw mandrel one end through supporting base and being installed vertically on support base end face by screw thread, regulate that the screw mandrel other end is vertical with the rear end face of anti-skidding top board is rotatably connected, the front end face of anti-skidding top board for and column laminating, the lower surface of anti-skidding top board and ground fit.
