Accompanying drawing explanation
Fig. 1 is the top view of this utility model escalator roller fatigue test device.
Fig. 2 is that the A-A in Fig. 1 is to sectional view.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
Refer to Fig. 1 and 2, a kind of escalator roller fatigue test device, including workbench 1, can around self axial rotation be arranged on workbench 1 driving wheel 11, drive driving wheel 11 rotate reducing motor 13, be installed in the mechanism for testing of the periphery of driving wheel 11.Reducing motor 13 is fixed on workbench 1 by motor supporting base 14.In order to test 4 rollers simultaneously, the quantity of described mechanism for testing is 4, and 4 mechanism for testing are distributed in the periphery of driving wheel 11 and 4 described mechanism for testing are oppositely arranged centered by driving wheel 11 two-by-two.In other embodiments, the quantity of mechanism for testing can also be other even numbers such as 6,8,10.
As shown in Figure 2, each described mechanism for testing include main body 9, be slidably arranged in the front portion of main body 9 with away from or near driving wheel 11 slide block 8, be fixed on the front portion of slide block 8 for being rotationally connected the fixing axle 10 of escalator roller 12, the guide 6 being arranged on slide block rear, the thrust induction apparatus 7 that is connected between guide 6 and slide block 8, and can before and after adjustably be arranged on main body 9 rear end to support forward the distance rod 4 of guide 6.In the present embodiment, each main body 9 is supported on workbench 1 by a base 3 respectively.The support seat 81 being fixedly arranged at the front end with a L-shaped of slide block 8, fixing axle 10 is fixed on support seat 81, and fixing axle 10 is actual uses a bolt, and its top is additionally provided with one for the nut 101 limiting escalator roller 12.
The rear end of main body 9 is installed with end cap 5, and distance rod 4 is threaded on end cap 5 and the front end of distance rod 4 pushes against guide 6 after end cap 5.Main body 9 actually time one hollow structure, guide 6, thrust pickup 7 and slide block 8 can be arranged on body interior with seesawing along main body its length direction.By rotary thrust bar 4, the pressure between escalator roller 12 and driving wheel 11 can be regulated quickly and easily.
In order to test the pressure suffered by escalator roller 12 exactly, distance rod 4, guide 6, thrust induction apparatus 7 and described slide block 8 are positioned on same centrage, the extended line of described centrage is through the center of circle of driving wheel 11, after so may insure that both driving wheel and escalator roller are tangent, can stably transmission both when driving wheel drives escalator roller to rotate.
And, parallel with the rotary centerline of driving wheel 11 for installing the axial line of fixing axle 10, so, after escalator roller 12 is arranged on fixing axle 10, when test, the side of escalator roller 12 is the most tangent with the side of driving wheel 11, and escalator roller 12 and driving wheel 11 are in approximate horizontal position.
Operating for convenience, distance rod 4 is screw, and screw is additionally provided with the nut 41 distance rod 4 and end cap 5 locked.
When escalator roller 12 is carried out testing fatigue, set test condition as roller linear velocity V=0.8m/s, thrust F=1000N ± 50N, testing time T=250H.During test,
Escalator roller 12 is arranged on fixing axle 10, is limited by nut 101, prevent escalator roller 12 from deviating from.Then being turned by distance rod 4 regulates forward with push-tight guide 6, slide block 8 before guide 6 and thrust pickup 7 is slided, escalator roller 12 on fixing axle 10 is pushed against with driving wheel 11, observing that thrust is 1000N by thrust induction apparatus 7, then to fix distance rod 4 motionless for fastening nut 41.Being 0.8m/s by driving wheel 11 rotational speed regulation to linear velocity V again, start reducing motor, thrust F of observation thrust induction apparatus test was interior change in 250 hours, as thrust F is not above margin of tolerance 1000N ± 50N, then being considered as test to pass through, this escalator roller is qualified products, it is possible to use.
The escalator roller fatigue test device smart structural design of the present embodiment, stable and reliable in work, it is possible to multiple escalator roller 12 to be tested simultaneously, improve testing efficiency.
