Description

A kind of lift rail perpendicularity and gauge robot measurement
Technical field
The present invention relates to the special equipment measuring technique, be specially a kind of lift rail perpendicularity and gauge robot measurement.This robot a kind ofly relies on permanent magnetism absorption vertically to climb to carry out the semiautomatic machine people of slide rail verticality and gauge DATA REASONING.
Background technology
Cage guide is carried out verticality and the gauge measurement is important task of elevator industry.Current China, flourish along with economy, increasing high buildings and large mansions appear among each city, and are accompanied by being on the increase of skyscraper, and the quantity of the box elevator of thing followed sedan-chair is also more and more.The security of elevator, high efficiency, comfortableness also become basic, the important techniques performance requirement to elevator operation.Therefore, the I&M for elevator has also received increasing concern accordingly.
The lift rail perpendicularity detection method has experienced two stages basically: the phase one is to utilize manual work that slide rail verticality is carried out segmentation to detect; For example traditional messenger wire method; Adopt traditional method of hanging vertical line to guarantee the verticality that guide rail is installed; Utilize earth gravity field exactly, the steel wire upper end of a Φ about 0.6 is fixing, the weight in lower end.Adopt this method at first will scaffold erecting, the model frame is installed, segmentation is hung vertical line and is carried out the rectification of model up and down to guide rail then.It is accurately simple that this method seems, but in the site operation of reality, be difficult to guarantee the accurate precision of hanging down.At first, weight itself is a pendulum, and one 100 meters long weight reaches 20 seconds hunting period, is difficult in the short time to stop.So, weight is being placed organic oil with the increase damping usually, even but consuming time so also long, influence precision simultaneously.Secondly; The weight line receives the influence of wind easily, and 10kg, the long weight of 100m are if only receive the influence of 1g transverse force (power that is equivalent to an ant strength size) at the weight place; Will make messenger wire depart from 10mm, just about 20 rads error at the 100m place.Once more, the microvibration of buildings is easy to be delivered to the vertical line of tightening, and causes vertical missing.Simultaneously, the stair shaft dark, wet, long-term operation is healthy unfavorable to survey crew, and easy fatigue causes the personal error of measuring process.Particularly in the elevator maintenance stage, owing to there has not been framing scaffold, be difficult to hang the vertical line operation especially, the squareness measurement of elevator is just difficult more; Subordinate phase is that testing process is accomplished by robot.In recent years, elevator industry has occurred being used for the laser plummet that slide rail verticality detects, and uses high-precision perpendicular laser beam to replace hanging vertical line, and accuracy of detection improves a lot.Be accompanied by the appearance of laser plummet, lift rail perpendicularity detects and on measuring process and method, has obtained new progress.
Shanghai Communications University machinery and power institute, and " based on the cage guide study on high-precision measurement of Flame Image Process " paper that Ji Haizhong etc. deliver (referring to Guo Lifeng. the research of the uneven compliance measurement of cage guide, modeling and sedan-chair case Properties of Horizontal Vibration of Cabin: [doctorate paper]. Tianjin: proposed a kind of CCD of utilization camera, fixing and receiving trap, laser transmitting system, video acquisition and processing system etc. the .2005 of University Of Tianjin) and be combined as holistic verticality measurement device.Laser transmitting system comprises: transfer the generating laser and the tripod of vertical functional automatically, video acquisition and processing system comprises: ccd video camera, video frequency collection card, software systems, image glass sheet and imaging thin plate.Seek profile, the oval least square fitting of least square method and method such as preferred through maximal value filtering, image burn into image expansion, OTSU binaryzation, Canny conversion; Can confirm the center of laser facula fully; Just can adjust then, thereby improve scope and precision that cage guide detects greatly the verticality of guide rail.This method provides to the lift rail perpendicularity measurement a good measuring basis is provided.But; This measuring method still needs artificial participating in the overall process; Workload is big, and too busy to get away framing scaffold, has limited the application in the elevator maintenance operational phase; And because manpower restriction measurement point quantity can be not too many, even have only so several times mistake measurement also will cause the guide rail curve-fitting results than mistake.
University Of Tianjin has proposed a kind of novel elevator slide rail verticality measuring instrument; Make measuring instrument be close to guide rail with strong magnet; Measuring instrument links to each other with car through a pull bar; Laser plummet is fixedly arranged in guide rail bottom, sends a perpendicular laser beam downwards (referring to Ji Haizhong etc., based on the cage guide study on high-precision measurement of Flame Image Process: the .2006 of Shanghai Communications University).During measurement, car drives measuring instrument and on guide rail, moves, and the CCD camera that is installed on measuring instrument receives laser facula, and through the displacement of Computer Image Processing identification spot center, this change in displacement has promptly reflected the guide rail vertical error.This method realizes simple, and measuring process does not need manual intervention, and measuring speed is fast.But discover that there are some defectives in above-mentioned cage guide measuring instrument: measuring instrument is passed in level and vertical vibration in (1) cage operation process inevitably, thereby causes uncontrollable measuring error; (2) at the guide rail installation phase owing to there is not lift car, can't use this measuring instrument to carry out guide rail and detect and correct, usable range is limited greatly.
