Chinese utility model patent CN201520782808X《Elevator brake parameter detecting instrument》With CN204514293U《One Kind 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, 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 precision that acceleration test can reach is ± 2%, and by the speed and distance values 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 inspection to speed, distance Survey the requirement that precision is ± 1%.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of easy to operate, measuring accuracy meets state The elevator brake parameter detecting instrument of family's standard.
The utility model is achieved by following technical proposals:
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, is surveyed The cylindrical of magnetic rollers is close in elevator wire rope side during amount, the elevator steel wire generation magnetic attraction with contact, above and below steel wire rope Magnetic rollers are driven to rotate when mobile;The magnetic rollers are connected with rotary encoder, and magnetic rollers, which rotate, drives rotary coding Device is rotated, and the information of magnetic rollers rotation is exported by rotary encoder, 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 that thin-walled hub is embedded in annular magnet, 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 tablet personal computer.
The utility model compared with prior art the advantages of be:
(1) magnetic rollers formula wire rope displacement measurement apparatus is used, to the accuracy of detection of elevator speed, braking distance ± 0.5% is can reach, is significantly better than the accuracy of detection of the elevator speed obtained using acceleration transducer and braking distance.
(2) magnetic rollers speed measuring device is used, the cylindrical of magnetic rollers produces magnetic attraction, steel wire with the elevator steel wire contacted Drive magnetic rollers to rotate when rope moves up and down, can effectively reduce the survey that the steel wire rope sliding cylindrical with magnetic rollers triggers Error is measured, improves accuracy of detection.
(3) Wheel structure of magnetic rollers is that thin-walled hub is embedded in annular magnet, 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 formed 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.
