Abstract
The utility model relates to a winch sensor with high detection precision, belonging to the technical field of metering equipment. The winch sensor comprises a housing, the central part of which is provided with a rotting shaft. A bearing is arranged on the rotating shaft inside the housing. A toothed disk is disposed on the bearing. Double proximity switches are arranged on the inner wall of the housing corresponding to the toothed disk. The main structural points are that the number of teeth of the toothed disk is an even number no less than 22.
Description
Technical field
the utility model belongs to metering outfit technical field, relates in particular to a kind of drawworks sensor.
Background technology
the drawworks sensor that comprehensive logging instrument, gas detection logging instrument are used is 12 tooth sensors, and using 2 phase differential is 12 winch discs of probe measurement of 90 °, 2 road signal intensities during through probe.By the collection of outside phase detector phase demodulation, rolling counters forward and acquisition software, reach the object of measuring hook height; In conjunction with drilling state, and then measurement depth.
the every circle of traditional drawworks sensor produces 12 pulse signals, when every meter of calculating of logging equipment is once bored, and winch precision 12 pulses/circle.When core drill enters, every 20cm calculates while once boring, and precision is inadequate.In addition, 1 bearing is used in its rotating shaft, without locating device, cannot change, and belongs to disposable products.
Summary of the invention
the utility model is exactly for the problems referred to above, and the drawworks sensor that a kind of accuracy of detection is high is provided.
for achieving the above object, the utility model adopts following technical scheme, and the utility model comprises shell, shell middle part is provided with turning axle, on the turning axle of enclosure, be provided with bearing, on bearing, be provided with fluted disc sheet, on outer casing inner wall, corresponding to fluted disc sheet, be provided with two approach switchs; The number of teeth of its structural feature fluted disc sheet is to be more than or equal to 22 even number.
as a kind of preferred version, the number of teeth of fluted disc sheet described in the utility model is 22.
as another kind of preferred version, bearing described in the utility model comprises clutch shaft bearing and the second bearing, on the turning axle between clutch shaft bearing and the second bearing, is provided with spacing jump ring; Described turning axle adopts axostylus axostyle, and one end of axostylus axostyle is axostylus axostyle outer shroud, and the other end of axostylus axostyle is provided with external thread; One nut is twisted and on external thread, is locked clutch shaft bearing and the second bearing.
secondly, spacing jump ring described in the utility model inner side is provided with bearing inner ring compress gasket.
in addition, to cross center of circle center line angle be 20.45 ° to described in the utility model pair of approach switch.
the utility model beneficial effect.
the number of teeth of the utility model fluted disc sheet is to be more than or equal to 22 even number.The accuracy of detection of drawworks sensor is brought up to and is greater than 22 pulses/circle by 12 pulse/circles; Improve drawworks sensor precision, meet the technical requirement of 20cm drilling time log.
Accompanying drawing explanation
below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection domain is not only confined to the statement of following content.
fig. 1 is the utility model structural representation.
fig. 2 is the utility model fluted disc sheet and two approach switch relative position schematic diagram.
fig. 3 is the two approach switch output of pulse signal figure of the utility model.
in figure, 1 is that nut, 2 is that axostylus axostyle, 3 is that clutch shaft bearing, 4 is that bearing inner ring compress gasket, 5 is that spacing jump ring, 6 is that the second bearing, 7 is that shell, 8 is that outer shroud, 9 is that pair approach switchs, 10 are fluted disc sheet.
Embodiment
as shown in the figure, the utility model comprises shell 7, and shell 7 middle parts are provided with turning axle, on the turning axle of shell 7 inside, is provided with bearing, is provided with fluted disc sheet 10 on bearing, on shell 7 inwalls, corresponding to fluted disc sheet 10, is provided with two approach switchs 9; The number of teeth of fluted disc sheet 10 is to be more than or equal to 22 even number.
the number of teeth of described fluted disc sheet 10 is 22.Fluted disc sheet 10 rotates a circle, by each approach switch, produce 22 pulse signals, each approach switch relative rotation axi axle center angle in 90 °, by phase detector phase demodulation and impulse meter counting, realize phase demodulation and the winch step-by-step counting of the utility model drawworks sensor, thereby realize the monitoring to the detection of hook height and well depth.8VDC stabilized voltage supply is provided to each approach switch, rotation turning axle, approach switch output two pulse signals sequence chart as shown in Figure 3,90 ° of the phase differential of two pulse signals, the pulse signal that outside phase detector can be 90 ° to phase differential carries out phase demodulation, external counter is counted the pulse after phase demodulation, by acquisition software, realizes the detection to the detection of hook height and well depth.
described bearing comprises clutch shaft bearing 3 and the second bearing 6, on the turning axle between clutch shaft bearing 3 and the second bearing 6, is provided with spacing jump ring 5; Described turning axle adopts axostylus axostyle 2, and one end of axostylus axostyle 2 is axostylus axostyle 2 outer shrouds 8, and the other end of axostylus axostyle 2 is provided with external thread; One nut 1 is twisted and on external thread, is locked clutch shaft bearing 3 and the second bearing 6.Adopt duplex bearing to locate turning axle, facilitate turning axle dismounting, drawworks sensor shell, turning axle can be reused.
described spacing jump ring 5 inner sides are provided with bearing inner ring compress gasket 4.Adopt bearing inner ring compress gasket 4 to make clutch shaft bearing 3 and the second bearing 6 arrange more stable.
it is 20.45 ° that described pair of approach switch 9 crossed center of circle center line angle.
be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
