Fig. 3 is understructure schematic diagram.
Embodiment
A kind of adjustable variable working condition wire rope detection of dynamic test unit have one for arrange wire rope installing mechanism and for driving the control device with Information Monitoring.
As shown in figures 1 and 3, the pedestal stand 6 that the column I 62 that installing mechanism comprises base 61 and is vertically fixed on base two ends is formed, wherein, base is made up of three longitudinal channel-section steels and four transverse channel steels; In order to ensure the stability of support post I, add A-frame to respectively column I, and longitudinal channel-section steel is connected and fixed by screw bolt and nut and transverse channel steels.Each column I 62 is installed the support wheel that two can regulate height, base 61 between two columns is vertically fixed with column II 7, column II 7 is provided with friction driving roller, the top of friction driving roller is provided with the adjustable pinch roller that can regulate height, the base of column II both sides at least arranges the tension adjustment wheel that can regulate height, and steel wire is successively through support wheel tension adjustment wheel and friction driving roller.
As shown in Figure 2, control device comprises controller, the propulsion system for driving friction driving roller are connected with controller, the Hall element group for gathering wire rope magnetic leakage signal is connected with controller, the speed pickup for gathering wire rope movement velocity is connected, the power module be connected with controller with controller.In the present embodiment, described propulsion system comprise the frequency converter be connected with controller, are connected the asynchronous machine for driving friction driving roller to rotate with frequency converter.Described controller adopts industrial control computer.Described speed pickup adopts digital encoder, is arranged on friction driving roller.Described Hall element group adopts ring-shape Hall sensor group.
Support wheel 1, adjustable pinch roller 3, friction driving roller are all arranged on its respective position by bearing and bearing seat with 4 and tension adjustment wheel 5, can bear wire rope and run the swing brought, and guarantee that testing table is stable; Wire rope 2 is by the load-bearing of four larger-size support wheels 1, and the contact area of going change wire rope 2 to take turns with tension adjustment by the support wheel 2 that size is less, increases the friction force that wire rope 2 is taken turns with tension adjustment.
Support wheel 1 plays and bears wire rope 2 weight and driven effect.When the adjustment of wire rope movement velocity drags by the asynchronous motor of transducer drive the friction that belt wheel connects, driving wheel completes, and wire rope movement velocity can reach 0 ~ 20 m/s.The adjustment of steel wire rope tension is that the height difference of being taken turns by tension adjustment is completed.
The course of work: Frequency Converter Control drives asynchronous motor motion, asynchronous motor is by band wheel drive friction-type driving wheel; The digital encoder on driving wheel is made to obtain the travelling speed of wire rope, to reach the function accurately controlling rotating speed by being arranged on friction; Adjustable pinch roller is fixed on the top of friction-type driving wheel by the spring of its both sides, applies a longitudinal force to wire rope, to increase the friction force of friction-type driving wheel; Tension adjustment wheel has larger lift capability, by the height of adjustment of tonicity regulating wheel, makes wire rope can bear different tension variation; Utilize the magnetic leakage signal of ring-shape Hall sensor group to wire rope to gather, after signal is nursed one's health by signal conditioner, signal is made a gift to someone and is arranged in the signals collecting board of industrial control computer, achieve the collection to defect in rope signal; Utilize the Labview software development of NI company multi-channel signal acquiring system, complete the display to defect in rope magnetic leakage signal, and the signal processing function utilizing Labview powerful, realize the analysis and treament to defect in rope signal.The invention has the beneficial effects as follows and can regulate the travelling speed of wire rope and tension force, thus the simulation of test to wire rope operating condition, the Acquire and process system of exploitation defect in rope magnetic leakage signal, provides reliable experiment porch to wire rope detection of dynamic.
