Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the embodiment one said Unit Installation structural representation of the utility model;
Fig. 2 is the displacement measuring instrument structural representation of the embodiment one said device of the utility model.
Embodiment
Embodiment one:
Present embodiment is a kind of scrambler sensing equipment position self-checking device, and Fig. 1 is the scheme of installation of said device on windlass and windlass institute draw-off equipment.Said device comprises: be installed in the displacement measuring instrument 3 on the guide rail 2 of windlass Towed Unit 1, described displacement measuring instrument is connected with arithmetic element 4, and described arithmetic element is connected with scrambler 5 on being installed in the windlass cylinder; Described displacement measuring instrument is seen Fig. 2, comprising: be fixed on two fixed mounts 301 on the said guide rail, between described two fixed mounts slide rail 303 be set, described slide rail is provided with two position transducers 302 that can on slide rail, move.
The described device of present embodiment is installed on the equipment that windlass and windlass draw.By the equipment of windlass traction, can be equipment such as hanging basket, coaster, cage, be the equipment that has guide rail, displacement measuring instrument is installed on the guide rail, measures moving and variation by the equipment of windlass traction.The data measured through displacement measuring instrument write down and computing through arithmetic element, compare with the data that are installed in the scrambler on the windlass cylinder, with any position deviation of confirming that the windlass scrambler occurs.
Said arithmetic element can be the PLC Programmable Logic Controller, can also be microcontroller, linkage controller, in a broad sense, all can be used as the described arithmetic element of present embodiment as long as have the controller of programing function.Arithmetic element can be a kind of independently controller, also can with control entire equipment the shared controller of central processing unit.
The described displacement measuring instrument of present embodiment has two position transducers, and these two position transducers can be near switch, or other can export the sensor of displacement electric signal, like Hall element, photovalve or the like.
Two position transducers are installed in respectively on the displacement measuring instrument slide rail, at a distance of 1-3 rice.Use linear regression to calculate, calculating principle is following:
If the position of first position transducer is Y1; The position of second position transducer is Y2.When by the equipment process Y1 of windlass traction, arithmetic element can be read the respective value X1 of Y1 on scrambler, and when by the equipment process Y2 of windlass traction, arithmetic element can be read the respective value X2 of Y2 on scrambler.
With Y1, Y2, X1, X2, bring the linear equation group into:
Y1=aX1+b
Y2=aX2+b
Calculate a, the value of b; With a, the value of b is the substitution equation once more, forms linear equation:
y=a
x?+?b
