Embodiment
The utility model is a kind of step roller test unit of escalator, as shown in Figure 1, 2, 3, comprising: frame 1, casing 10, drive unit 21, driving wheel disc 5, force loading device 3, clamping device 9, water injector 4 and control system 11.
Frame 1 is provided with casing 10, is fixed with installation panel 2 in casing 10.Drive wheel disc 5 to be positioned at installation panel 2 fronts, drive unit 21 is positioned at installation panel 2 rears, and connects with driving wheel disc 5 by transmission shaft 22, drives and drives wheel disc 5 to move in a circle.
Installation panel 2 fronts driving centered by wheel disc 5, be evenly distributed in some groups and be the roller fixing bases that spoke line direction is arranged, every group of roller fixing base is fixed on roller by the clamping device 9 on it one end in the nearly center of circle of spoke line.As shown in Figure 2, roller fixing base comprises the first pedestal 25, second pedestal 26 that can move perpendicular to installation panel direction with respect to the first pedestal 25 edges being fixed on installation panel and is positioned at adjustment disk 18 between the two.Clamping device 9 is fixed on roller 7 on the second pedestal 26, rotation adjustment disk 18, can the second pedestal be moved along the tooth bar of the first pedestal by gear and tooth bar group 27, thereby change the distance of the second pedestal with respect to installation panel, change roller 7 and drive wheel disc 5 distance in the axial direction.It adjusts result as shown in Figure 3, different rollers is on different axial locations, there is different axial distances from driving wheel disc, there is different surface of contact, the step chains that simulation roller is built in structure between interior pin link plate is about its thickness of 1/2 at the loading end of ladder sprocket wheel position roller, has reflected that step roller exists diverse location bearing capacity size and the roller bearing capacity acting surface actual condition causing not of uniform size in actual motion.
Force loading device 3 is integrally installed on the second pedestal 26, and it comprises servo loading motor 14, screw rod 15, extending arm 17 and pick-up unit, and wherein pick-up unit has further comprised pressure transducer 20 and displacement transducer 16.The output terminal of servo loading motor 14 is connected with screw rod 15, and pressure transducer 20 one end are connected in screw rod 15 other ends and are connected in extending arm 17, and the end of extending arm 17 is fixedly connected with roller 7.Servo loading motor 14, by the transmission of screw rod 15 and extending arm 17, makes roller 7 along driving moving radially of wheel disc.Described pick-up unit 8 has comprised pressure transducer 20, for monitoring in real time the stressing conditions of roller operational process, exceedes the scope of setting automatic feedback is carried out to auto-compensation to control system if stressed.Described displacement transducer 16 is for monitoring in real time abrasion condition the real time record of roller.
Further, in order to simulate better the working environment of roller for outdoor version escalator or moving sidewalk, at the inwall of casing 10, water injector 4 is set.Control the spraying function of water injector 4 by control system, the water that whole process of the test sprays can flow back to pond 23 by water container 24, recycles.
When use, first roller 7 is arranged on the clamping device 9 of roller, whole test unit can be tested 1～10 roller simultaneously, rotates adjustment disk 18, adjusts roller 7 and makes it to meet default scope with the surface of contact that drives wheel disc 5 and make to drive wheel disc and the contact distance of roller in moving cooperation.In control system, set in advance the travelling speed that drives wheel disc 5, drive the travelling speed of wheel disc 5 to can be exchanged into roller travel line speed 0～2m/s.After drive unit 21 starts, drive wheel disc 5 to move in a circle drive, drive the rotation of wheel disc 5 that the roller that makes to contact is with it rotated thereupon.By control system 11 and man-machine interface 12 arrange power load size, start load time after start servo loading motor 14.In the time reaching default loading force, servo loading motor 14 is shut down.When wearing and tearing appear in certain number roller, increase while not reaching default loading force with driving the contacting distance of wheel disc, servo loading motor can produce auto-compensation and load according to demand different power.In the time that coming unstuck appears in certain number roller, cracking etc. lost efficacy, corresponding position limitation protection switch 19 will move, and transmission instruction is to control system auto stop and record the out-of-service time and emergency alarm bell and pilot lamp 6 move.Meanwhile, corresponding extension arm 17 shrinks, and roller 7 leaves and drives wheel disc 5, guarantees device security.Every group of force loading device 3 controlled by control system 11 is independent, and certain group appearance does not all affect the normal work of other groups when abnormal.
At the step roller test unit of escalator of the present utility model, test efficiency is high, can test 1～10 group of roller simultaneously; Can independently gather the ruuning situation of 1～10 group of roller, coming unstuck appears in roller, cracking etc., while inefficacy, control system was by auto stop and record the out-of-service time, and the result after acquisition process can directly store or output device 13 is exported; Can simulate roller at outdoor work environment; Stress surface can regulate roller operation time, simulation roller actual operating mode on escalator or moving sidewalk; Can automatically load according to time and magnitude of load that imposed load is set the stressing conditions of simulation roller actual motion on escalator or moving sidewalk; Can fully verify reliability, the security of roller, improve roller design quality, thereby improve the quality of escalator or moving sidewalk.
