Embodiment
As shown in Figure 1, Figure 2 and Figure 3, quick measurement car and the detector 9 of well enclosure distance of the present utility model include
Battery 1 and for installed in the top of lift car 16（Refer at the top of the outer wall of car 16）Self-level(l)ing device 2, automatic leveling dress
Put and housing 3 is fixedly connected with 2, single-chip microcomputer 4, audible-visual annunciator 5, wireless transport module 6, data storage 7 are provided with housing 3
With data acquisition module 8, angular adjustment rotating shaft is installed on housing 3, the He of angular transducer 10 is installed in angular adjustment rotating shaft
Laser range sensor 11；The direction that laser range sensor 11 launches laser when rotating shaft is in initial position is horizontal direction；
Self-level(l)ing device 2 and single-chip microcomputer 4 are connected by supply line with battery 1 respectively, and supply line is provided with switch 12, opens
12 are closed to be arranged on housing 3；The Laser emission end of laser range sensor 11 is located on the axis of angular adjustment rotating shaft, so that
When angular adjustment rotating shaft rotates, the Laser emission end of laser range sensor 11 is kept not relative to the locus of car 16
Become.Laser range sensor 11, data acquisition module 8, data storage 7, audible-visual annunciator 5 and wireless transport module 6
Electric energy directly or indirectly derives from single-chip microcomputer 4.Angular adjustment rotating shaft is conventional shaft like parts, not shown.
The data storage 7 is connected with usb 13.So as to facilitate single-chip microcomputer 4 to be set by data storage 7 with terminal
It is standby to carry out rapid data transmission.
The data acquisition module 8 includes analog signal amplifier 14 and the A/D being connected with analog signal amplifier 14
Modular converter 15, analog signal amplifier 14 are connected with laser range sensor 11, A/D modular converters 15 and the phase of single-chip microcomputer 4
Connection.
Single-chip microcomputer 4 is using C52 types single-chip microcomputer 4, it is preferred to use model AT89C52 ATMEL single-chip microcomputer 4.It is automatic to adjust
Leveling device 2 can use various existing ripe automatic leveling equipment, if three-dimensional Science and Technology Ltd. of Tontru of Shenzhen is in patent
Described a kind of self-level(l)ing device 2 in 201510258840.2.
The wireless transport module 6 is bluetooth module or wifi module or zigbee modules.
During installation, the frictional force between angular adjustment rotating shaft and housing 3 is adjusted（Housing 3 is arranged on by axle sleeve in rotating shaft
When upper, by controlling fit clearance and the friction between the regulation rotating shaft of the means such as frosted processing and axle sleeve being carried out to mating surface
Power）, make that there is larger frictional force between angular adjustment rotating shaft and housing 3, angular adjustment do not can be manually rotated in operating personnel
During rotating shaft, angular adjustment rotating shaft will not be rotated voluntarily.
Well enclosure typically will not be clean and tidy shiny surface, and label 18 show the projection on well enclosure 17 in Fig. 3.
Using above-mentioned detector 9 measurement car and well enclosure 17 apart from when, with the side of the well enclosure 17 of elevator door institute face
Xiang Weiqian to.
First step is that detector 9 is attached into the top nose of car 16, operating personnel's hand by its self-level(l)ing device 2
It is dynamic by axis of rotation to initial position, now the Laser emission end of laser range sensor 11 is flush with car front end；
, can be neat in the front end of laser range sensor 11 and car front end face irrelevancy by setting angular adjustment rotating shaft
When, by rotary laser distance measuring sensor 11, measurement laser range sensor 11 and a datum mark of car front end face selection
The distance between, with reference to measurement the distance between laser range sensor 11 and well enclosure, converse datum mark（Car front end
Face）The distance between well enclosure.When angular adjustment rotating shaft rotates, the space bit at the Laser emission end of laser range sensor
Put and keep constant（At axis）, avoiding the locus at the Laser emission end of laser range sensor from changing influences to survey
Measure the accuracy of result.
Second step is standing in the top of car 16, upper and lower operation car 16, observation detector 9 and well enclosure 17
Between whether have scratch phenomenon, if scratch phenomenon then adjusts the installation site of detector 9；
Third step is after being not in scratch phenomenon between detector 9 and well enclosure 17 when confirming that car 16 is run,
Car 16 is set to run to the top of well enclosure 17 or bottom；
Four steps is that operating personnel open the startup detector 9 of switch 12, laser range sensor 11 is launched laser；
Now laser range sensor 11 launches forward laser in the horizontal direction；Car 16 is set to run downward or upward to well enclosure 17
The other end, in the running of car 16, laser range sensor 11 persistently measures laser range sensor 11 and well enclosure 17
The distance between x, the x values that laser range sensor 11 will measure（That is the distance between car front end and well enclosure）Pass through data
Acquisition module 8 is persistently sent to single-chip microcomputer 4；X values are continued logging data memory 7 by single-chip microcomputer 4；
In the running of car 16, when x value is more than 15 centimetres, single-chip microcomputer 4 controls audible-visual annunciator 5 to send acousto-optic
Alarm, operating personnel are reminded to be handled.
Among four steps progress, wireless transport module 6 continues to pass through the value of car 16 and the distance x of well enclosure 17
Wireless signal is sent, and the staff where the operating personnel and elevator at the top of car 16 in building passes through terminal（Such as
The equipment that mobile phone, flat board, computer etc. have wireless transmission function）Real-time monitor and detection data.
When radio transmitting device failure needs to export data again, transfer data to terminal using usb 13 and set
It is standby.
Above example is only to illustrative and not limiting the technical solution of the utility model, although with reference to above-described embodiment pair
The utility model is described in detail, it will be understood by those within the art that：The utility model can still be entered
