Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing:
The system of fast tuning aircraft level of the present invention is based on following equipment, including electronic platform scale 1, four screw synchronous are gone up and down
Device, total station subsystem, main control computer, control cabinet 7, cable and the wheel stopper for embedding application software.
The electronic platform scale 1, four screw synchronous lifting devices, total station subsystem pass through cable and answer with described embed
It is connected with the computer of software, the computer of embedded application software is placed in control cabinet 7, and application software includes the lifting control of scale body
Software, horizontal adjustment software and weight center of gravity software for calculation processed.
The electronic platform scale 1 mainly by upper scale body, lower scale body, four weighing sensors, a terminal box array at.Entirely
Electronic platform scale 1 is placed on the hoistable platform 4 at the top of four screw synchronous lifting devices, and lower scale body and hoistable platform 4 are connected.Electronic table
Scale 1 contains three altogether, respectively carrying front and back wheel, when installation, removes scale body upper table surface, three weighing platforms are mounted in ground and keep
Scale body upper table surface is concordant with grade level, moves to weighing platform Weighing Area convenient for aircraft；Wheel stopper is placed on scale body, is used for
Airplane wheel is limited, stabilization of the aircraft in leveling is kept.
There are three the four screw synchronous lifting device settings, respectively corresponds three electronic platform scales 1, and main includes that lifting is flat
Platform 4, elevating mechanism 2, servo motor 3, motor servo driver and PLC controller.Hoistable platform 4 is installed under electronic platform scale 1
Side, laser displacement sensor 5 are placed in 1 side of electronic platform scale.When work, laser displacement sensor 5 detects adjustable height, and in real time
The elevation information of transmission hoistable platform 4 gives scale body elevating control software as value of feedback, meanwhile, scale body elevating control software is sent
It instructs to PLC controller, PLC controller controls motor servo driver, and driving servo motor 3 drives the silk in elevating mechanism 2
Thick stick rotation, four screw synchronous rotation, converts rotational motion into linear motion, the final raising and lowering for realizing hoistable platform 4.
In addition, in elevating mechanism 2, the protective devices such as the travel switch limited up and down are set, when touch switch, hoistable platform 4 stops, and
Only allow to move backward, to guarantee platform safety movement in allowed limits.Simultaneously be furnished with handwheel 8, handwheel 8 by gear with
Lead screw connection is, it can be achieved that manually and automatically two kinds of control modes, and when being allocated to manual gear, staff can pass through handwheel 8 and rotate silk
Thick stick movement, when being allocated to automatic catch, directly controls driver by scale body elevating control software.
The full-automatic ranging subsystem of 3D is mainly thin and ranging software forms by total station 6, measurement hand.The total station
6 uses come card TS16 model.When work, total station 6 is placed in ground, can flatten automatically within the scope of certain angle, and pass through electricity
Cable is connect with control cabinet.When systematic survey, can the thin control of hand, can also directly capture feature on data processing terminal panel
Point, Survey Software automatic measurement as built in it.
As shown in Fig. 2, the specific steps of adjustment level are as follows:
Step 1, aircraft is moved into Weighing Area, the limit of wheel stopper is placed by wheel；
Step 2, three sections or the identical outstanding ruler one end of multiple lengths are fixed at the water transfer flat spot on airframe, hang the another of ruler
One end nature hanging, so that the water transfer flat spot on aircraft extends to visual range；
Step 3, outstanding ruler end and datum mark on aircraft are captured with total station 6, ranging software survey calculation is between the two
Distance, and calculated result is transmitted to the horizontal adjustment software of the aircraft in main control computer；
Step 4, the laser displacement sensor 5 in four screw synchronous lifting subsystem feeds back 4 height of hoistable platform and will be anti-
Feedback value is transmitted to the horizontal adjustment software of the aircraft in main control computer；
Step 5, the horizontal adjustment software of machine is according to the value of feedback of 3,4 steps, and judging aircraft, whether adjustment is horizontal；
Step 6, if meeting condition, aircraft adjustment is horizontal, and otherwise, scale body elevating control software sends instructions to elevator
Structure 2, hoistable platform 4 act；
Step 7, return step 3 circuit sequentially, until aircraft adjustment is horizontal.
The observing and controlling process and principle of aircraft fast tuning level: before measurement, by the identical outstanding ruler one of three sections or multiple lengths
End is fixed with the level-off point on airframe, other end nature hanging, so that the water transfer flat spot on aircraft extends to visual model
It encloses.When measurement, rangefinder is placed in ground, after its automatic leveling, opens the sky that laser beam is directed toward outstanding ruler nature hanging end
Between location point and datum mark, or from measurement hand thin panel or data processing terminal panel on directly capture on aircraft outstanding ruler end
End and datum mark, ranging software quickly calculates the two o'clock distance of capture as built in total station 6, realizes water transfer flat spot and base
The measurement of relative distance on schedule, measurement result are transmitted to scale body elevating control software eventually by its included communication interface.Step
In rapid 5, if the relative distance that total station 6 is measured is labeled as △ Xi (i=1,2,3), maximum value is labeled as △ Xmax in △ Xi,
If △ Xmax is target value when aircraft levels, each relative distance precision is 1mm when aircraft levels.Judgement, if | △ Xi- △ Xmax |
≤ 1mm, then point leveling is motionless, otherwise compares value of feedback and target value, it is soft that the difference of the two is sent to scale body elevating control
Part, scale body elevating control software judge after receiving the difference, if △ Xi- △ Xmax≤1mm, the water transfer flat spot are corresponding
Hoistable platform 4 rises, if △ Xi- △ Xmax > 1mm, the corresponding hoistable platform 4 of the water transfer flat spot declines, and sends instructions to
PLC controller, control driver driving servo motor 3 act, and hoistable platform 4 is gone up and down, and is as follows recycled and is judged, until value of feedback
Consistent with target value, three water transfer flat spots level locking, then aircraft level levels.
As embodiment of the present invention, the scheme further includes two modules of application software, i.e. data acquisition module
And data management module, two Module-embeddings, according to measurement result, realize computer and aircraft weighting system into computer application software
The human-computer interaction of system and data output.
The horizontal adjustment system of aircraft can carry out quickly horizontal adjustment to aircraft, meanwhile, four screw synchronous go up and down subsystem
Lead screw have lifting self-lock function, total station 6 measurement accuracy is high, can be flattened automatically according to surface state, environmental suitability is strong.
Therefore, aircraft level tune correcting delay precision is high, stability is good doing for the horizontal adjustment system of aircraft, and system is safe and reliable.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
