Description
Technical field
It is a kind of test in the mechanical devices such as elevator, crane more specifically the present invention relates to a kind of detecting instrument
The special detector of haulage cable linear velocity in operation.
Background technology
In the mechanical devices such as elevator, crane haulage cable linear velocity in operation be important detection project it
One, the detection method of prior art is as follows：
The rotating speed of drive motor is detected using revolution counter, is computed by rotating speed, speed reducing ratio, three numerical value of rope sheave diameters
Obtain the operation linear velocity of haulage cable.
Using EC-2100 or EC-900 speedometer direct measurements, by the peripheral speed ring (being commonly called as the roller that tests the speed) of speedometer and fortune
Haulage cable in row is lightly contacted, and can measure the linear velocity of steel wire rope.
State on the implementation in detecting, measurement apparatus need and tested mechanism's good contact, generally by the hand-held inspection of reviewer
Instrumentation is surveyed, its operation level directly affects accuracy of detection.
Chinese invention patent CN201210163507X《Elevator wire rope displacement measuring device》, disclose Application Optics figure
Image displacement detecting system realizes the scheme of contactless displacement measurement, and technical merit is advanced.At present remain problem be, test essence
Degree is relatively inaccessible to ± 1% index, treats further perfect.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of easy to operate, measuring accuracy meets national mark
A kind of haulage cable linear velocity detector of alignment request.
The technical scheme is that：
A kind of haulage cable linear velocity detector, including tachogenerator, connecting rod and fixator, its velocity sensor
Using magnetic rollers formula wire rope displacement measurement apparatus, the Wheel structure of magnetic rollers is embedded in annular magnetic for thin-walled roller shell
Iron, magnetic rollers it is cylindrical on form magnetic attraction；The cylindrical of magnetic rollers is close in haulage cable side during measurement, is being led
Draw and driven when steel wire rope is moved up and down magnetic rollers rotation, the linear speed of the information transmission haulage cable rotated by magnetic rollers
Degrees of data.
The haulage cable linear velocity detector, the magnetic pole orientation of its annular magnet is radial pattern, inner circle and outer ring
Circularize the magnetic pole of magnet.Its magnetic rollers is connected with rotary encoder, and magnetic rollers are rotated and drive rotary encoder rotation, are led to
Cross the information that rotary encoder output magnetic rollers are rotated.
The fixator of the haulage cable linear velocity detector is magnetic stand；Its connecting rod is helical spring type elasticity
Connecting rod, or thin plate springs formula flexible connecting rod.
Present invention advantage compared with prior art is：
(1) using magnetic rollers formula wire rope displacement measurement apparatus, accuracy of detection can reach ± 0.5% to velocity sensor
More than, better than the precision index that Application Optics picture displacement detecting system is obtained, and reliability is preferable with repeatability.
(2) magnetic rollers speed measuring device is used, the cylindrical of magnetic rollers produces magnetic attraction with the steel wire for contacting, on steel wire rope
Magnetic rollers are driven to rotate when lower mobile, the measurement that can effectively reduce the steel wire rope sliding initiation cylindrical with magnetic rollers is missed
Difference, improves accuracy of detection.
(3) Wheel structure of magnetic rollers is embedded in annular magnet for thin-walled roller shell, overcomes magnetic material and is difficult to essence
The difficulty of processing, simplifies manufacturing process.
(4) magnetic pole orientation of annular magnet is radial pattern, the cylindrical magnetic pole that magnetic rollers are constituted with inner circle.With common axle
To magnetizing, annular magnet is compared, and can make the cylindrical magnetic attraction enlarged relative of magnetic rollers, makes the side magnetic attraction of magnetic rollers
It is relative to diminish.
Chinese invention patent CN201210163507X《Elevator wire rope displacement measuring device》, disclose applied magnetic and lead
The technical scheme of ccd sensor is set up to wheel, its magnetic directive wheel is not belonging to speed measuring device, and magnetic directive wheel does not possess the work(that tests the speed
Can, the purpose for setting magnetic directive wheel is different from technology essential factor with the present invention.
