Description
Technical field
The present invention relates generally to a kind of connecting bridge levelling gear and its detection components.
Background technology
Referring to Fig. 1.Fig. 1 shows traditional connecting bridge levelling gear schematic diagram.As shown in figure 1, traditional connecting bridge leveling
Mechanism 10 includes drive device 11, swing rod 12, driving lever 13, the first detection switch 14 and leveling wheel 15.Drive device 11 is installed
On connecting bridge 100 (see Fig. 2), the one end of swing rod 12 is articulated with the drive device 11, and the other end is articulated with driving lever 13
One end, first detection switch 14 and leveling wheel 15 are installed in the other end of driving lever 13.Leveling wheel 15 can be one
Rubber wheel.
When connecting bridge 100 is abutted against aircraft, drive device 11 drives swing rod 12 to drive the motion of driving lever 13 to make leveling wheel 15
Contact and keep certain pressure compressing on airframe, when passenger goes on or off the plane or during handling goods, airframe can on
Rise or decline, and due to there is certain pressure between leveling wheel 15 and airframe, rise or decline process in airframe
In, leveling wheel 15 can roll on airframe, and because leveling wheel 15 links together with the first detection switch 14, first examines
The signal that slowdown monitoring switch 14 rotates with regard to that can detect leveling wheel 15 relative to driving lever 13, and the signal detected is supplied to one
PLC, PLC calculate the distance that airframe rises or falls according to received signal, and control connecting bridge 100 leading section follows
Airframe rises or falls, and is abutted against so that connecting bridge remains in the suitable height and position of airframe.
Referring to Fig. 2.Fig. 2 show connecting bridge be abutted against aircraft initial position and connecting bridge rise after position versus signal
Figure.As shown in Fig. 2 the rear end of connecting bridge 100 is articulated with a fixed buildings such as terminal 200, stretched before and after the energy of connecting bridge 100
Contracting, so that its leading section can be abutted against on airframe.As previously described, when airframe rises or falls, PLC controls boarding
The leading section of bridge 100 rises or falls therewith.However, the structure type of connecting bridge 100 determines the leading section of connecting bridge 100 at present
Can be simultaneously elastic in rising or decline, as shown in Fig. 2 after the leading section of connecting bridge 100 rises, compared to initial bit
Put, connecting bridge 100 generates displacement L in the horizontal direction.Once the leading section of connecting bridge 100 produces horizontal position in the horizontal direction
Move, the pin joint between the driving lever 13 and swing rod 12 of levelling gear also can be and then movable, the leveling wheel 15 of levelling gear
It is always maintained at oppressing on airframe, the movable of hinge between such driving lever 13 and pendulum swing rod 12 will certainly cause
The scroll-up/down on airframe of leveling wheel 15, and the scroll-up/down of leveling wheel 15 then means leveling wheel 15 relative to driving lever 13
Relatively rotate.This detection means being installed on driving lever 13 that relatively rotates detects, so that PLC erroneous judgements are
Airframe is being fluctuated, so as to cause detection error.
Referring to Fig. 3, Fig. 3 shows to cause error-checking schematic diagram due to the angle change of driving lever in levelling gear.
As shown in figure 3, the leading section of connecting bridge 100 telescopic displacement G in the horizontal direction, in the process, the one end of driving lever 13
It is changed to by initial position (see solid line) away from aircraft position (see dotted line), and has given birth to variable angle amount α, while driving lever 13
The other end produces displacement H in vertical direction, and a segment distance is moved up and down along airframe equivalent to leveling wheel 15.Therefore step on
The elastic change of the leading section of machine bridge 100 in the horizontal direction, it can drive the pin joint of the bottom of driving lever 13 is front and rear to move
Dynamic, driving lever 13 is also accordingly changed relative to the angle of leveling wheel 15, and this change is also mounted on driving lever 13
Detection means detects, so as to cause PLC erroneous judgements to be that leveling wheel 15 moves up and down in airframe, so as to cause detection to miss
Difference.
Referring to Fig. 4, Fig. 4 shows the detection error curve of traditional connecting bridge levelling gear.As can be seen from Figure 4：With
The increase (more and more far away from aircraft) of the leading section retraction distance of connecting bridge 100, changing caused detection by horizontal range misses
Poor curve is in steeply rise trend, it means that the detection error as caused by changing horizontal range is with the front end of connecting bridge 100
The increase of portion's retraction distance and increased dramatically；Simultaneously as shown in figure 4, the increase of the leading section retraction distance with connecting bridge 100,
Also ascendant trend is presented in detection error curve caused by the angle change of driving lever 13, i.e., is examined caused by the angle change of driving lever 13
Survey error also with the increase of the leading section retraction distance of connecting bridge 100 gradually to increase, because total detection error is level
Detection error caused by distance change and detection error sum caused by angle change, contract so that with the leading section of connecting bridge 100
The increase of distance is returned, total detection error increased dramatically.Therefore, connecting bridge levelling gear will result in theory of mechanics at present
Larger detection error, so as to endanger the safety of aircraft.
Analyze and may determine that more than, if the leveling wheel 15 of connecting bridge levelling gear can also make with connecting bridge it is elastic
Linear motion, is just avoided that such a detection error.The mechanism needs of the elastic linear motion of leveling wheel 15 can generally be realized
The mechanisms such as guide rail, sliding block or roller are applied to, but in practice, because airframe has certain radian, on aircraft
It can easily cause to move along a straight line to one component upwardly or downwardly of mechanism of this linear motion, this power when rising or declining
Clamping stagnation or guide rail deformation, therefore this mechanism is unreliable.
In addition, in traditional connecting bridge levelling gear, the first detection switch 14 is a limit switch or encoder, and it is detected
