Description
Technical field
The present invention relates to connecting bridge leveling testing agency, and in particular to a kind of vertical constant pressure type connecting bridge automatic leveling detection
System.
Background technology
Connecting bridge levelling gear is located at front edge of airport pickup port foremost, due to aircraft load-carrying during on-board and off-board and handling goods
The change of position of centre of gravity, height of the aircraft door away from ground has tens centimetres of change, if connecting bridge height is not adjusted therewith
It is whole, just occur that front edge of airport pickup port movable floor makes inconvenient or front edge of airport pickup port movable floor above and below passenger be higher than aircraft away from hatch door door
Hatch door and the phenomenon for colliding outward opening aircraft door, the effect of levelling gear are to ensure that height becomes aircraft door from the ground
During change, the open height that picks does same tracking adjustment, front edge of airport pickup port movable floor leading edge is remained certain height away from aircraft cabin
Degree.
The automatic leveling detection method that current connecting bridge is used mainly has following two ways：
1st, leveling arm is fixed on torque motor, and torque motor is fixed on boarding bridge joint side, is characterized in leveling
Detection means is vertical with front edge of airport pickup port side all the time；The design method may insure levelling detection device (leveling wheel) at connecting bridge
In under any posture constant pressure can be applied to aircraft skin, but levelling detection device vertical positive can not be ensured in aircraft
Covering.
2nd, levelling detection device (leveling wheel) is arranged on a fixed connecting rod, and connecting rod is fixed on boarding bridge joint side
Face, the connecting rod makes levelling detection device be pressed on aircraft skin using spring mechanism；This method is because when boarding picks and aircraft
The difference of distance and aircraft type, the pressure of application is also different, it is impossible to ensures constant to the pressure of aircraft skin, is directed to simultaneously
Different aircraft types and connecting bridge posture, levelling detection device it is also vertical with front edge of airport pickup port side all the time and it cannot be guaranteed that with it is winged
Machine covering is vertical.
When connecting bridge is in the case that inclination picks, when now front edge of airport pickup port rotates left side, front edge of airport pickup port occurs that the left side is high
The right it is low not into level state, be now accomplished by adjustment movable floor make the forward position of movable floor parallel with the door line of aircraft
(level), although movable floor have adjusted angle, but levelling detection device (leveling arm and the leveling of the design of both the above connecting bridge
Wheel) original position is held at, therefore can not ensure vertical with aircraft skin holding during work, the second way can not also be protected
Demonstrate,prove contact constant force.When automatic leveling wheel and aircraft skin out of plumb, frictional force reduces, and sideslip or rain occur during motion
Snowy day gas skid, be easily caused levelling detection device can not normal work or detection failure, to the passenger on aircraft and connecting bridge
Cause certain potential safety hazard.
The content of the invention
For the problems of the prior art, the present invention provides a kind of vertical constant pressure type connecting bridge automatic leveling detecting system,

Arm and galianconism end are hinged with first position limiting slide block and the second position limiting slide block respectively；It is described it is long-armed be provided with and the activity
The parallel connecting rod rotation axis of floor rotary shaft, the rotary shaft is fixed on front edge of airport pickup port crossbeam；The leveling motor bottom plate is close to institute
The one end for stating leveling arm is provided with the bottom plate rotary shaft parallel with the movable floor rotary shaft；When the movable floor is around the work
When dynamic floor rotary shaft is rotated both clockwise and counterclockwise angle [alpha] respectively, the L-shaped connecting rod is driven to distinguish around the connecting rod rotation axis
Counterclockwise with the angle beta that turns clockwise, then the leveling motor, leveling arm and leveling wheel is driven integrally to distinguish the clockwise and inverse time
Pin anglec of rotation α so that the movable floor and the leveling arm keep vertical.
Preferably, the connecting rod rotation axis are arranged at the long-armed close inflection point side.
Preferably, the scope of the angle [alpha] is 0~15 °.
Preferably, the scope of the angle beta is 0~15 °.
Preferably, the leveling motor is constant force torque motor.
, can it is determined that after the particular location of above-mentioned movable floor rotary shaft, connecting rod rotation axis and floor rotary shaft pivot point
By calculating and designing long-armed and galianconism the length of L-shaped connecting rod, and distance of the connecting rod rotation axis pivot point away from inflection point, with reality
Existing movable floor is identical with the direction of rotation of leveling arm and angle, so that it is guaranteed that leveling arm and movable floor remain vertical.
From the above, it can be seen that the present invention possesses advantages below：
The present invention is on the basis of existing automatic leveling detection means, by between movable floor and leveling motor bottom plate
The link gear that is made up of sliding groove, sliding shoe, L-shaped connecting rod and rotary shaft is set, and calculates the design parameter of each linkage part,
Can be achieved the spinning movement of movable floor is conducted to leveling motor bottom plate so that leveling wheel all the time with it is postrotational actively
Plate keeps vertical, finally make it that leveling arm keeps completely vertical with aircraft skin and pressure is invariable, it is ensured that connecting bridge certainly
By the difference of weather and the posture that picks changing for frictional force will not be occurred for dynamic levelling detection device, it is to avoid breakked away or skidded, carry
High detection accuracy so that the automatic flat-adjustable function of connecting bridge is able to normally realize, farthest ensure that aircraft and multiply
The safety of visitor.
