Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
The schematic diagram of the device of the resistance to snow load performance of the measurement cover from sun in the application is shown in Fig. 1, wherein, has loaded bag 1 and be evenly suspended on loading frame by lanyard, in bag, load the counterweight iron sand according to criterion calculation mass; What shading product detection test specimen tiled is fixed on test-piece stand 7; Load frame 4 and be positioned at the vertical upper space of test-piece stand 7, its upper surface is vertically connected at the bottom of the bottom of two guide poles 3 and the body of rod of electric cylinder 2, with bearing on guide pole 3, and two guide poles equidistant be positioned at electric cylinder 2 both sides; Test-piece stand 7 is placed the shading product test specimen needing to measure; The execution that electric cylinder 2 can manipulate loads the displacement of frame 4 above-below direction, make to load frame 4 along guide pole 3 vertical movement, electric cylinder 2 specifications and models are maximum load 9000N, 380V/50Hz, when loading frame 4 and moving down along guide pole 3, move to until loads bag 1 and all drop on sunshade test specimen, and lanyard is lax, load is all applied on test specimen 6, can produce predetermined loading force to the shading product test specimen on test-piece stand 7; The specifications and models of test stand 7 and loading frame 4 are aluminium section bar 8080,6030; Laser range sensor 8 is for measuring electric cylinder, loading the displacement of the parts such as frame and shading product test specimen; Control box 5 is used for setting the working procedure loading frame and load bag entirety, and the operation of controlled loading frame and loading bag entirety carries out this work according to the process set.
During measurement, first, hang according to the size of test specimen and the grade of resistance to snow load the quantity and weight that load bag 1, loading bag is canvas bag, and built with lead button, owing to adopting lead button to load, relatively snow load situation, also can change weight arbitrarily as requested; According to the requirement of standard, every square meter needs 9 load(ing) points, and load(ing) point also according to any shift position of the size of test specimen, and can increase and decrease quantity.
Then, by controlling electric cylinder 2, make to load frame 4 also to move down along guide pole 3, move to assigned address, load bag 1 and all drop on sunshade test specimen, and lanyard relaxes, load is all applied on test specimen, test load FN is applied to shading product, loads frame 4 and stop moving and after keeping load 5 minutes, discharge this load FN.The displacement in the centre of record shading product, load afterwards on frame 4 and move this load of unloading, unload this load after 2 minutes, the change of record shading product test specimen and damaged condition, to measure and under recording power disarm state, stretching, extension, the power of withdrawal needed for shading product, such as test specimen is sunshading board, and operating physical force is manually opened, the power of closedown needed for sunshading board.
Continue as above to operate, by controlling electric cylinder 2, make to load frame 4 and again move down, translational speed is less than 2m/min, applies safety load FS to shading product, and after keeping 5 minutes, the change of record shading product test specimen and damaged condition.
As above operating also can repeatedly several times, finally, by the change of shading product test specimen of having recorded and the operating physical force of damaged condition and measurement, draws testing result.
When operating above-mentioned each measuring process, adopt touch-screen and PLC control system, the operation carrying out interface controls, and this touch-screen and PLC control system can arrange the parameter such as grade, sample dimensions length and width, the size of test load FN, the size of safety load FS of test duration, working time, sample center offset, resistance to snow load; And rising, the decline of electric cylinder can be controlled, and electric cylinder is made to be parked in current location by stop button; In addition, the parameters such as associated load, time etc. also all can set again in systems in which, requires and the resistance to snow load grade of standard with satisfied difference.
When testing, for the hard shading product having frame, be placed on on test-piece stand, for soft roller shutter class without the soft shading product of frame, then can be fixed between the square beam in the middle of test-piece stand, the downstream position of the frame of adjustment loading simultaneously.
Although be below described the preferred embodiments of the present invention by reference to the accompanying drawings; but the invention is not restricted to above-mentioned embodiment; above-mentioned embodiment is only schematic instead of determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to present inventive concept and claim; multiple similar enlightenment and accommodation can be drawn, and make corresponding simple change and amendment, be similar to such conversion and all fall within protection scope of the present invention.
