The beneficial effects of the utility model: the utility model can realize many group rollers and test simultaneously, has saved the time, has improve test efficiency; By the setting of force snesor and spring, drive leading screw to produce loading force to Lug-Down device and control, warranty test data accurately and safety; The setting of vibration transducer, guarantees that roller occurs that tired breakaway situation can Timeliness coverage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model schematic cross-section;
Fig. 2 is the utility model testing table schematic side view;
Fig. 3 is the utility model roller clamping schematic top plan view.
Embodiment
As Fig. 1, escalator roller fatigue tester, comprises testing table, and is positioned at some load maintainers of testing table both sides.As shown in Figure 2, this every side of embodiment testing table has ten load maintainers, testing table comprises mounting platform 11, cylinder 10 and drive motor 12, mounting platform 11 is provided with two relative the second bearing seats 14, cylinder 10 two ends are arranged on the second bearing seat 14 by axle and bearing, drive motor 12 is connected with cylinder 10 one end axle by chain 13, and mounting platform 11 is provided with transparent plastic capping 18, this transparent plastic capping 18 is positioned at above cylinder 10.Cylinder 10 adopts 45 steel plates to roll and forms, surface is through quenching and antirust treatment, cylinder 10 two ends are welded with flange and reinforcement, cylinder 10 is connected with drive motor 12 by the sprocket wheel on axle, chain 13, drive motor 12 is placed in below cylinder 10, this kind of layout can shorten testing machine entire length, saves space.Because cylinder 10 input speed is less demanding, moment of torsion is mainly used in overcoming system friction square, therefore the power meter synchronous rotational speed of drive motor 12 is less demanding, selects six grades of 22kW ac variable frequency speed regulation asynchronous motors, synchronous rotational speed is 1000r/min, and nominal torque is 210N.m.
As Fig. 2, load maintainer comprises the shaft coupling 2, leading screw 4, screw set 5, force snesor 6 and the coupling spindle 7 that are connected successively with Lug-Down device 1, and coupling spindle 7 is connected with roller clamping 9 by spring 8, and leading screw 4 is arranged on clutch shaft bearing seat 3.As Fig. 3, roller clamping 9 is made up of U-shaped bearing 16 and bearing pin 17, and bearing pin 17 two ends are arranged on two relative sidewalls of U-shaped bearing 16, are rotatablely equipped with roller 20 in the middle part of bearing pin 17, and U-shaped bearing 16 sidewall is also provided with vibration transducer 15.
Roller 20 and cylinder 10 are fitted, and bear the radial pressure of regulation, and roller 20 is driven by cylinder 10, to simulate the actual condition of roller 20.Roller 20 symmetry is arranged on cylinder 10 both sides, can offset rolling radial force.Load maintainer can adopt cylinder to load or electric threaded shaft loads, the utility model is that electric threaded shaft loads, leading screw 4 is driven to load to tested roll wheel assembly by Lug-Down device 1 (i.e. reductor), leading screw 4 has auto-lock function, therefore loading force is only by the impact of lead screw position, once after lead screw position determines, loading force is constant; But it does not possess pooling feature, if tired breakaway appears in roller, then can produce moment impact to charger, therefore load bar must be equipped with buffer spring.Assuming that loading force is 5000N.m, then the reductor that optional power is 0.18kW, reduction gear ratio is 56.67, output torque is 45N.m, rotating speed is 25r/min can meet request for utilization.
The utility model can realize many group rollers and test simultaneously, has saved the time, has improve test efficiency; By the setting of force snesor and spring, drive leading screw to produce loading force to Lug-Down device and control, warranty test data accurately and safety; The setting of vibration transducer, guarantees that roller occurs that tired breakaway situation can Timeliness coverage.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
