Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to Fig. 1, wheel-chair steady stability system safety testing device of the present invention, comprises base 1, test platform 2, leading screw 3, handle 4, baffle plate slide rail 5, baffle plate 6, turnover preventor structure slide rail 7, turnover preventor structure 8, pressure transducer 9, angular transducer 10, fixing lock ring 11, support bar 12, angular display unit 13 and pressure display unit 14.
Below base 1, be provided with four Level tune supports 16, by the flatness of the whole proving installation of Level tune bracket adjustment.
The front end of test platform 2 is rotatably connected with the front end of base 1.
The lower end of leading screw 3 is rotatably connected with the rear end of base 1, and the middle rear end by trap 15 and test platform 2 is movably connected.Be provided with two cantilevers 21 in test platform 2 rear ends, trap 15 be connected between two cantilevers by two bearing pins and empty set on leading screw 3.
Handle 4 is threaded with leading screw 3 and is connected with trap 15 transmissions, can drive the rear end of test platform 2 to move up or down by rotary handle 4, realizes an angle of test platform inclination.Between handle 4 and trap 15, be connected by the mutually nested slip of concaveconvex structure.
Baffle plate slide rail 5 is arranged on the front portion of test platform 2.
Turnover preventor structure slide rail 7 is arranged on the side of test platform 2.
Turnover preventor structure 8 is erected on turnover preventor structure slide rail 7 and can moves forward and backward along turnover preventor structure slide rail.This turnover preventor structure comprises base plate 81, vertical rod 82, contiguous block 83 and cross bar 84; Base plate 81 is connected and can locates by bolt with turnover preventor structure slide rail slip 7, vertical rod 82 is fixed on base plate 81, one end of contiguous block 83 is connected with vertical rod 82 is adjustable, the other end of contiguous block 83 is connected with cross bar 84 is adjustable, contiguous block 83 can be along vertical rod 82 up-down adjustment, and cross bar 84 can be along contiguous block 83 left and right adjusting.
Fixing lock ring 11 is arranged on the rear portion of test platform and is positioned at the rear of pressure transducer.
Course of work principle of the present invention is: by wheel-chair to be measured according in standard, require to carry out steady state (SS) or least steady state (SS) regulate, and test is placed on wheel-chair according to standard-required with dummy, the wheel braking of consideration wheel-chair or wheel are not braked under two states and are placed on the test platform being horizontal according to its direction of tumbling, regulating wheel Wheel-chair makes the rotation of its angle of overturn parallel with test platform tilt axis, and error is ± 3 °.Then retrain and limited wheel Wheel-chair by fixing lock ring and turnover preventor structure, time be used for preventing that wheel-chair from rolling or sliding on inclined-plane in test, freely rotate to tumble or do not affect wheel-chair around the contact point of wheel and test surfaces and freely rotate and tumble around axle accordingly but do not affect wheel-chair.Turnover preventor structure can inclined degree or the distortion of limited wheel Wheel-chair on test platform, but do not affect the stability of wheel-chair, can avoid wheel-chair to topple over backward because of out of trim.
In the time of rotary handle, trap can be along leading screw moving linearly, drive test platform to move with trap near one end of leading screw with this, the other end of test platform is connected by a turning axle with base, makes can freely rotate by turning axle between the test platform other end and base.When test platform one end is when leading screw rises or decline, the other end and base keep rotation, just can make the angle forming between test platform and base change, thereby realize the adjusting of test platform bevel angle.The static rollover performance of thus can testing wheel Wheel-chair tumbling under direction and steady state (SS) in difference.According to the requirement in testing standard, regulate test platform to horizontal level, wheel-chair is positioned on test platform according to the direction of tumbling, and by fixing lock ring and turnover preventor structure, wheel-chair is limited, bevel angle to test platform regulates, until be 1 o'clock at all wheel-chair wheels of test platform rising end to test platform pressure, determine the tip-over angle of test platform around turning axle, and give corresponding display by angular transducer and pressure transducer by data feedback, revision test, records repeatedly test result.Wherein be used for measuring the angular transducer of test platform and horizontal plane angle, measuring accuracy is ± 0.2 °.
Lean forward stability as example take testing wheel Wheel-chair, test is placed on the test platform 2 being horizontal with wheel-chair, wheel-chair should be towards the direction of dip plane descending.Make the line parallel with test platform tilt axis (error ± 3 °) of two front axle, will test and be placed on wheel-chair with dummy's (meeting GB/T 18029.11 requires).Wheel-chair wheel is not braked, made it in steady state (SS).If needed can by fixing lock ring 11 catch on wheel-chair vehicle frame before bring in and strengthen fast pulley Wheel-chair, avoid wheel-chair to topple over backward because of out of trim.Rotary handle 4, drive the rear end of test platform 2 to move up and down along leading screw 3 by trap 15, regulate the angle of inclination of test platform 2, until be 1 o'clock at the wheel-chair wheel of test platform rising end to test platform pressure, determine the tip-over angle of test platform around turning axle, pressure transducer 9 is connected with angular display unit 14 with pressure display unit 13 by electric wire with angular transducer 10, and platform stressing conditions and angle of inclination are shown in display.Measure and record the angle of overturn, be rounded to 1 °, then test platform is reduced to horizontal level, finish this test.
