Rotary head 8 is hinged and connected with expansion bolt 9.
Further, testing agency 1 is built-in with lithium battery and GPRS/3G/GPS module, and the top of testing agency 1 is provided with
For sunshade and the cover 6 of rainwater-proof, the bracket 7 for fixing solar panel, solar battery are provided with above cover 6
Plate is the lithium battery power supply inside testing agency 1.
Further, testing agency 1 is built-in with quarter-bell Rouser, which changes awake device using independent button cell
Power supply.After completing sampling operation, measurement host can set the starting time of work next time, and it is completely disconnected then to measure host
Electricity opens constantly worked by quarter-bell Rouser again, realizes power saving to the maximum extent.
The working principle of the utility model and use process is as follows:
The measuring device of the utility model is using the line laser that laser range finder 5 emits as the horizontal line of reference, by laser
Hot spot be irradiated in the detection faces 2 of measuring device, linear array CCD scanning device 3 carrys out flyback in detection faces 2 in the horizontal direction
The judgement, it can be achieved that light spot shape and position is retouched, and is filled by measurement hot spot in the change in location of detection faces 2 to calculate measurement
The sedimentation value set.
As shown in figure 3, the mode that pole connection when in use, can be used in this measuring device measures.First is measured
Device and last measuring device are placed in standard point, remaining measuring device is individually positioned on each monitoring point, is passed through
The position of laser range finder 5 is adjusted, the line laser for launching the laser range finder 5 of previous measuring device is incident upon next
In the detection faces 2 of measuring device, and it is located at the center of detection faces 2；By scanning back and forth for linear array CCD scanning device 3, i.e.,
The judgement to light spot shape and position can be achieved；Meanwhile while the transmitting line laser of laser range finder 5, laser ranging can measure
Distance of the instrument 5 apart from detection faces 2 can determine whether the original that sedimentation occurs by measuring the distance change of laser emission point and detection faces
Cause is then caused by the sedimentation of detection faces if distance is there is no variation；It is then detection faces if distance is changed
Inclination.
By taking existing high-speed rail construction as an example, existing high-speed rail construction is substantially all to use overhead mode, according to existing
Job specfication, as soon as general 35 meters or so bridge piers, one kilometer of needs nearly 30 bridge pier, and these bridge piers are required to arrange
Personnel carry out periodic measurement sedimentation and shift value, and the measurement content of this part needs to extend through the construction of high-speed rail, operation.Together
When very manifold bridge pier and bridge geographical location it is also very special, also taken a lot of work very much using manual measurement, and in Special section,
Work or high-risk work are measured, annual railway department, which has to expend sizable man power and material, thus goes to handle.From height
The data that the construction party of iron obtains, the expense of the existing each bridge pier measurement of technology is at monthly 3000 yuan or so, one kilometer of height
Metal bridge pier is each in terms of measurement nearly to spend 10W or so, and the measuring device of the application is used to measure, and expense is too late
The 2% of traditional expense, and data can be uploaded in real time, measurement accuracy can achieve 0.1mm, be much higher than existing measurement
Technology, therefore there is great marketing condition.
The utility model has the beneficial effects that: 1) solve, datum mark in engineering survey is utilized, remote auto measures position
The problem moved and settled；It 2) can not real-time online measuring in terms of solving the sedimentation for measuring measured object in existing measurement method
Problem greatly facilitates measurement and construction, the management at scene etc.；3) linear array CCD scanning measurement method is used, linear array is passed through
CCD scanning means, which calculates the size of laser facula and center, measurement accuracy, can get to 0.1mm；4) measurement every time
1 minute or so is needed, and the upload of real-time measuring data may be implemented；5) existing witness mark can be made full use of, it will
Laser beam emitting device is placed into witness mark；6) measured using cascade system, can by reference to closure come into
Row adjustment；7) center of hot spot, the decaying and aging of the transmission power of laser tube are calculated by the shape of laser facula
Do not influence the result (aging and decaying of LASER Discharge Tube only influence the power of hot spot, do not influence the shape of hot spot) of measurement 8)
It is extremely low that unattended work, maintenance for a long time can be achieved；9) the device energy conservation mode created, every time after measurement, equipment
All fully powered-off shutdown carries out quarter-bell by internal independent real-time clock and wakes up work, may be implemented long-term unattended
Work.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
