Description
Technical field
The present invention relates to elevator technology field, more particularly to a kind of device for measuring car with well enclosure distance and measurement side
Method.
Background technology
In recent years domestic elevator accident partial accident be with car and well enclosure distance dependent, such as：When elevator hair
During raw failure, passenger pushs a blindness aside and saved oneself, and easily occurs hoistway falling accident.If elevator and well enclosure are no more than a spacing
From, it becomes possible to play a part of protection passenger safety, avoid unnecessary casualty accident.The distance of car and well enclosure is new rule
The project detected in detection as emphasis, to meet code requirement,《Elevator surveillance examine and periodic inspection rule-traction with by force
System driving elevator》Middle regulation：The spacing of car and the well enclosure in face of car entrance is not more than 0.15 meter, small for local height
In 0.5m or the cargo lift using vertically sliding door, the spacing can increase to 0.2 meter.
At present when carrying out elevator measurement car and well enclosure is examined apart from this, one people station of palpus is in car top, in stop
Between successively pause and open car door.Another inspector station observed in car car apart from well enclosure it is farthest one at, use
Ruler goes to measure distance of the above-mentioned car at well enclosure farthest one.This metering system not only influences personal security, operation
Property it is also not strong, and with may missing inspection.
Another measuring method used at present is：In car top measurement landing sill and well enclosure distance, while converting again
To car sill and well enclosure distance, 3 cms are differed.This measuring method is that artificial measured with ruler is seen with naked eyes
Examine, have very big error.
The content of the invention
It is an object of the invention to provide the detector of a kind of quick measurement car and well enclosure distance, nothing in measurement process
It must be paused in interlayer, and accuracy of measurement is higher.
To achieve the above object, quick measurement car of the invention and the detector of well enclosure distance include battery and use
It is provided with single in being fixedly connected with the self-level(l)ing device installed in elevator car roof, self-level(l)ing device in housing, housing
Angular adjustment is installed on piece machine, audible-visual annunciator, wireless transport module, data storage and data acquisition module, housing to turn
Angular transducer and laser range sensor are installed in axle, angular adjustment rotating shaft；Laser ranging when rotating shaft is in initial position
The direction of sensor emission laser is horizontal direction；Self-level(l)ing device and single-chip microcomputer pass through supply line and battery phase respectively
Connection, supply line is arranged on housing provided with switch, switch；Adjusted positioned at angle at the Laser emission end of laser range sensor
On the axis for saving rotating shaft.
The data storage is connected with USB interface.
The data acquisition module includes signal amplifier and the A/D modular converters being connected with signal amplifier, signal
Amplifier is connected with laser range sensor, and A/D modular converters are connected with single-chip microcomputer.
The wireless transport module is bluetooth module or wifi module or zigbee modules.
The present invention also aims to provide a kind of method that car and well enclosure distance are measured using above-mentioned detector, nothing
By laser range sensor installation site relative datum point front and back position how, can easily draw car and hoistway
The distance of wall.
To achieve the above object, the method for detector measurement car of the invention and well enclosure distance is successively according to the following steps
Carry out：
Using elevator door just to well enclosure direction as before to；Datum mark is used as using the front end bottom end of car vertical cross-section；
First step is that by its self-level(l)ing device detector is attached into car top front end, and operating personnel are manually by rotating shaft
Initial position is turned to, now the Laser emission end position of laser range sensor has three types, the first kind is laser
The front end of distance measuring sensor is located in front of datum mark in the longitudinal direction；Second Type is the front end of laser range sensor preceding
Rear is flush with datum mark upwards；3rd type is that the front end of laser range sensor is located at datum mark in the longitudinal direction
Rear；
Second step be standing in car top, run car up and down, whether have between observation detector and well enclosure
Scratch phenomenon, if scratch phenomenon then adjusts the installation site of detector；
Third step is after being not in scratch phenomenon between detector and well enclosure when confirming cage operation, to make cage operation
To well enclosure top or bottom；
Four steps is that operating personnel open switch startup detector, laser range sensor is launched laser；Then it is manual
The anglec of rotation adjusts rotating shaft, laser range sensor is rotated to laser the position being just incident upon on datum mark, and now angle is passed
Sensor sends the rotational angle α of angular adjustment rotating shaft relative initial position to single-chip microcomputer by data acquisition module, swashs simultaneously
Ligh-ranging sensor sends the distance between the laser range sensor measured and datum mark y to list by data acquisition module
Piece machine；
5th step is operating personnel's manual rotation angular adjustment rotating shaft, rotating shaft is back to initial position, and now laser ranging is passed
Sensor launches forward laser in the horizontal direction；Car is set to run downward or upward to the other end of well enclosure, in cage operation mistake
Cheng Zhong, laser range sensor persistently measures the distance between laser range sensor and well enclosure x, and laser range sensor will
The x values measured are persistently sent to single-chip microcomputer by data acquisition module；
When the position at the Laser emission end of laser range sensor is the first kind, single-chip microcomputer is calculated according to below equation
Car and well enclosure apart from d：D=sin（α -90 °）× y+x, and d values are continued into logging data memory；
When the position at the Laser emission end of laser range sensor is Second Type, single-chip microcomputer is calculated according to below equation
Car and well enclosure apart from d：D=x, and d values are continued into logging data memory；
When the position at the Laser emission end of laser range sensor is three type, single-chip microcomputer is calculated according to below equation
Car and well enclosure apart from d：D=x-sin（90 ° of-α）× y, and d values are continued into logging data memory；
During cage operation, when d value is more than 15 centimetres, single-chip microcomputer control audible-visual annunciator sends sound and light alarm, carries
The operating personnel that wake up are handled.
Among the 5th step is carried out, wireless transport module persistently passes through the value apart from d of car and well enclosure wireless
Signal is sent, and the staff where the operating personnel of car top and elevator in building monitors inspection by terminal in real time
Survey data.
The present invention has the advantage that：
Using the detector and measuring method of the present invention, the error that manual measurement is brought at utmost is avoided, accurate journey is measured
Degree is higher.In measurement process, car need not successively pause between stop and open car door, but can make car along well enclosure
Run incessantly from top to bottom or from bottom to up, so as to realize quick measurement.
