In order to achieve the above objectives, the utility model is achieved using following technical scheme:
A kind of system of fast tuning aircraft level, including three lifting devices, total station and control cabinet；
Three lifting devices are separately positioned below airplane wheel and are connected with servo motor, initial position and ground
Maintain an equal level, moving direction is vertical direction；
The total station is placed on the ground, and is popped one's head in towards three water transfer flat spots of aircraft and the aircraft reference point of setting,
And it is connect with control cabinet；
Control cabinet is connect with the servo motor of three lifting devices.
Preferably, three water transfer flat spots of aircraft are provided with the identical outstanding ruler of length, hang the nature hanging of ruler end.
Preferably, three lifting devices are provided with laser displacement sensor, and the probe court of laser displacement sensor divides into
It sets, the output end of laser displacement sensor is connect with control cabinet input terminal.
Preferably, lifting device is all made of four screw synchronous lifting devices.
Further, three lifting devices are provided with handwheel, and handwheel is connect by gear with lead screw.
Preferably, electronic platform scale is respectively and fixedly provided at the top of three lifting devices.
Preferably, wheel stopper is provided at the top of three lifting devices.
Compared with prior art, the utility model has the following beneficial effects:
The utility model is measured by using the relative position that total station exchanges level point and datum mark, and will measurement
Data are sent to control cabinet, and according to the data received, the lifting device that control three is arranged in below wheel rises control cabinet
Or decline, and then adjustment aircraft is horizontal, does not need manual operation, and then reduce human error, precision is high, and speed is fast, efficiency
Height realizes the automation control of aircraft calibration procedures.
Further, by the way that the outstanding ruler of equal length is arranged in water transfer flat spot and datum mark, the nature hanging of ruler end is hanged, makes to survey
The point of amount can extend to visual range, be convenient for measuring.
Further, control cabinet passes through the travel information command displacement distance that laser displacement sensor is fed back, and realizes adjustment
When accurate control.
Detailed description of the invention
Fig. 1 is the adjustment system structural schematic diagram of the utility model.
Wherein: 1- electronic platform scale；2- elevating mechanism；3- servo motor；4- hoistable platform；5- laser displacement sensor；6-
Total station；7- control cabinet；8- handwheel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
The system of the utility model fast tuning aircraft level is based on following equipment, including electronic platform scale 1, four screw synchronous
Lifting device, total station 6, control cabinet 7, cable and wheel stopper.
It is fixed using the identical outstanding ruler one end of three sections or multiple lengths with the level-off point on airframe, the other end is natural
Hanging, so that the water transfer flat spot on aircraft extends to visual range.
The electronic platform scale 1, four screw synchronous lifting devices, total station 6 are connect by cable with control cabinet 7.
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.Hoistable platform 4 is installed on 1 lower section of electronic platform scale, laser displacement
Sensor 5 is placed in 1 side of electronic platform scale, and the output end of laser displacement sensor 5 is connect with control cabinet input terminal.When work, swash
Optical displacement sensor 5 detect adjustable height, and the elevation information of real-time transmission hoistable platform 4 as value of feedback to control cabinet, together
When, control cabinet sends instructions to motor servo driver, and driving servo motor 3 drives the lead screw in elevating mechanism 2 to rotate, and four
Thick stick synchronous rotary converts rotational motion into linear motion, the final raising and lowering for realizing hoistable platform 4.In addition, elevator
In structure 2, the travel switch limited up and down is set, when touch switch, hoistable platform 4 stops, and only allows to move backward, to guarantee
Platform safety movement in allowed limits.Be furnished with handwheel 8 simultaneously, handwheel 8 connect by gear with lead screw, it can be achieved that it is manual and
Automatic two kinds of control modes, staff can be moved by 8 rotational lead screw of handwheel, can also be driven by control cabinet to servo motor
Device directly controls.
The total station 6 uses and comes card TS16 model.
Before measurement, the identical outstanding ruler one end of three sections or multiple lengths is fixed with the level-off point on airframe, it is another
Nature hanging is held, so that the water transfer flat spot on aircraft extends to visual range.When measurement, total station 6 is placed in ground, is realized
The measurement of water transfer flat spot and datum mark Relative vertical distance, if the measurement of the Relative vertical distance of a certain water transfer flat spot and datum mark
Value is positive number, then the level-off point is located above datum mark, and numerical value is Relative vertical distance, if a certain water transfer flat spot and datum mark
The measured value of Relative vertical distance be negative, then the level-off point is located at below datum mark, and numerical value is Relative vertical distance；Entirely
Instrument 6 of standing drop measurement result is sent to control cabinet 7, and control cabinet 7 controls four screw synchronous lifting devices according to data and carries out rising-falling tone
Whole, positive value four screw synchronous lifting devices of control move downward, and negative value controls four screw synchronous lifting devices and moves upwards, and makes to adjust
Level point is constantly drawn close to the relative position of datum mark, until three water transfer flat spots and datum mark are on same plane, is adjusted
It completes in school.
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.Therefore, the horizontal adjustment system of aircraft is doing aircraft level tune correcting delay precision height, stability
Good, system is safe and reliable.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within protection scope with novel claims.
