Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, this crane hydraulic cylinder amount of recovery on-line computing model is primarily of measurement main frame 1, wireless signal transmitter 2, wireless signal receiver 3, hand held controller 4 and datawire composition.Wireless signal transmitter 2 is connected with measurement main frame 1, and wireless signal receiver 3 is connected with hand held controller 4.Measure main frame 1 to form primarily of top 7, digital display meter 8, mark post 9, magnetic force suction base 10.Top 7 contacts with Barrel of Hydraulic Cylinders 5, is connected to digital display meter 8 intrinsic displacement sensor by mark post, and magnetic suction base 10 is connected with measurement main frame 1.
As shown in Figure 2, measuring main frame 1 is fixed on hydraulic cylinder piston rod 6 by magnetic suction base 10, Barrel of Hydraulic Cylinders 5 is withstood in main frame top 7, mark post 9 compression distance is controlled at 0.1-1.0mm, fix, use hand held controller 4 to carry out reference measurement and read each digital display meter 8 reference value, simultaneity factor starts timing automatically, when proceeding to 15 minutes, the end value of each measuring point digital display meter of automatic reading also shows on a display screen, press result of calculation key, display result of calculation (formula △ L=L2 – L1).
In test process, the self-clocking of hand held controller 4 built-in system, measure main frame 1 and compress mark post bar by top 7, mark post 9 connects digital display meter 8 intrinsic displacement sensor, displacement transducer reads displacement information, by wireless interface transmitting apparatus, related data is sent to hand-held control 4 panel, carries out Data Collection and calculating by the inner single-chip microcomputer of hand held controller 4, display final result.
This crane hydraulic cylinder amount of recovery on-line detector main frame 1 also can be used alone, by conventional test methodologies independent measurement oil hydraulic cylinder amount of recovery, only need read start and at the end of digital display meter numerical value, calculated difference can obtain corresponding amount of recovery, easy for installation, result is accurate.
