As can be seen here, escalator roller fatigue test device of the present invention effectively reliably can carry out torture test to escalator roller, and smart structural design of the present invention, easy to operate, works very reliable.
Accompanying drawing explanation
Fig. 1 is the vertical view of escalator roller fatigue test device of the present invention.
Fig. 2 is that A-A in Fig. 1 is to cut-open view.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1 and 2, a kind of escalator roller fatigue test device, comprise worktable 1, around self axial rotation ground reducing motor 13 of being arranged on driving wheel 11 on worktable 1, driving driving wheel 11 to rotate, the mechanism for testing of the periphery of driving wheel 11 can be installed in.Reducing motor 13 is fixed on worktable 1 by motor supporting base 14.In order to can 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 between two centered by driving wheel 11.In other embodiments, the quantity of mechanism for testing also can be other even numbers such as 6,8,10.
As shown in Figure 2, each described mechanism for testing comprises 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 slide block 8 front portion for be rotationally connected escalator roller 12 stationary shaft 10, be arranged on slide block rear guide 6, be connected to thrust inductor 7 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 worktable 1 respectively by a base 3.The front end of slide block 8 is fixed with the supporting seat 81 of a L shape, and stationary shaft 10 is fixed on supporting seat 81, and stationary shaft 10 is actual in the present embodiment, and what adopt is a bolt, and its top is also provided with one for limiting the nut 101 of escalator roller 12.
The rear end of main body 9 is installed with end cap 5, and distance rod 4 is threaded on the end cap 5 and front end of distance rod 4 and pushes against guide 6 through after end cap 5.Main body 9 in fact time a 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 inductor 7 and described slide block 8 are positioned on same center line, the extended line of described center line is through the center of circle of driving wheel 11, after can guaranteeing that both driving wheel and escalator roller are tangent like this, can stably transmission both when driving wheel drives escalator roller to rotate.
And, for the center of rotation line parallel of the axial line and driving wheel 11 of installing stationary shaft 10, like this, when escalator roller 12 is arranged on after on stationary shaft 10, when testing, the side of escalator roller 12 and the side of driving wheel 11 are just in time tangent, and escalator roller 12 and driving wheel 11 are in approximate horizontal position.
Conveniently operate, distance rod 4 is screw, screw is also provided with the nut 41 of distance rod 4 and end cap 5 being locked.
When carrying out testing fatigue to escalator roller 12, setting test condition is: roller linear velocity V=0.8m/s, thrust F=1000N ± 50N, test duration T=250H.During test,
Escalator roller 12 is arranged on stationary shaft 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 stationary shaft 10 is pushed against with driving wheel 11, observing thrust by thrust inductor 7 is 1000N, and then to fix distance rod 4 motionless for fastening nut 41.Be 0.8m/s by driving wheel 11 rotational speed regulation to linear velocity V again, start reducing motor, the change of thrust F in 250 hours of observation thrust inductor test, as thrust F does not exceed margin tolerance 1000N ± 50N, then be considered as test to pass through, this escalator roller is specification product, can use.
The escalator roller fatigue test device smart structural design of the present embodiment, working stability is reliable, can test simultaneously, improve testing efficiency to multiple escalator roller 12.
