The brake of elevator equivalent to automobile brake system, in view of characteristic of the elevator in space motion, elevator brake Brake system than automobile is more important, is one of essential elements of guarantee lift running safety.
The function of elevator brake will be embodied by stopping power, typically by elevator during detection elevator brake The operational factor of car evaluates the stopping power technical indicator of brake.At present in elevator industry detection elevator brake parameter Detecting instrument be elevator carry mass-synchrometer, conventional model have Stork PMT Co. of the U.S. EVA-625,Anhui Zhong Kezhigao companies DT-4A etc., instrument is placed in lift car during detection operation, can show that the operating speed of lift car and acceleration are write music Line, the parameters such as the speed of service, acceleration, run time and range ability can be obtained by special-purpose software.This quasi-instrument is many work( Can, it is universal, price is higher, volume is larger, and operation application is more complicated, using not extensive in the detection of elevator brake ability.
Chinese utility model patent CN201520782808X《Elevator brake parameter detecting instrument》With CN204514293U《One Plant handheld elevator braking distance detection means》, disclose and elevator is obtained by acceleration transducer run acceleration and then right This integrated acceleration obtains the technical scheme of elevator brake distance, and its construction is approximate with smart mobile phone, relatively simpler and more direct practicality.
Above-mentioned several prior arts, take the scheme of applied acceleration sensor, and weak point is:At present to elevator The acceleration test precision to be reached is ± 2%, and by the speed and distance values that are obtained to integrated acceleration, its precision refers to Mark will be less than ± 2%, it is impossible to meet national standard《Elevator test method GB/T 10059-2009》In to speed, the inspection of distance Survey the requirement that precision is for ± 1%.
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 Accurate elevator brake parameter detecting instrument.
The technical scheme is that:
A kind of elevator brake parameter detecting instrument, including elevator speed sensor and detection data processor, its elevator speed Sensor is connected with detection data processor, and elevator speed sensor uses magnetic rollers formula wire rope displacement measurement apparatus, surveys The cylindrical of magnetic rollers is close in elevator wire rope side during amount, and magnetic attraction is produced with the elevator steel wire for contacting, and steel wire rope is upper and lower Magnetic rollers are driven to rotate when mobile;The magnetic rollers are connected with rotary encoder, and magnetic rollers are rotated and drive rotary coding Device is rotated, and the information that magnetic rollers are rotated is exported by rotary encoder, and elevator brake is calculated through data processor for analysis During speed, deceleration and braking distance data.
The Wheel structure of magnetic rollers described in elevator brake parameter detecting instrument is embedded in annular magnet for thin-walled hub, in magnetic The cylindrical upper formation magnetic attraction of property roller;The magnetic pole orientation of the annular magnet is radial pattern, and inner circle circularizes magnetic with outer ring The magnetic pole of iron.
The detection data processor of elevator brake parameter detecting instrument is preferably panel computer.
Present invention advantage compared with prior art is:
(1) magnetic rollers formula wire rope displacement measurement apparatus are used, to elevator speed, the accuracy of detection of braking distance ± 0.5% is can reach, the accuracy of detection of the elevator speed and braking distance obtained using acceleration transducer is significantly better than.
(2) magnetic rollers speed measuring device, the cylindrical of magnetic rollers is used to produce magnetic attraction, steel wire with the elevator steel wire for contacting Drive magnetic rollers to rotate when rope is moved up and down, can effectively reduce the survey that the steel wire rope sliding cylindrical with magnetic rollers triggers Amount error, improves accuracy of detection.
(3) Wheel structure of magnetic rollers is embedded in annular magnet for thin-walled hub, overcomes magnetic material and is difficult to finishing The difficulty of work, 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.
