Abstract
The present invention relates to field of airplane design, provide a kind of airplane pod suspension cable overload shutoff device, hanger rope fixed bearing is fixed on housing, and hanger rope is through the groove on hanger rope fixed bearing, and hanger rope is stuck on hanger rope fixed bearing by blanking cover, and cutter head is fixed on tension arm; Hanger rope is contained in the fork ear of tension arm, being installed with being bolted to of track adjusting wheel pitches on ear, spring and tension arm are successively through on the guide rod of spring bearing, spring bearing is fixed on housing, tool rest is installed on hanger rope fixed bearing, 4 positioning guide pulleys are arranged on the side in housing hanger rope path, and safety pin is inserted into by the hole on cap in the groove on blanking cover.The present invention cuts off gondola hanger rope where necessary automatically, abandons gondola, ensures the flight safety of aircraft.
Description
Technical field
The present invention relates to field of airplane design, particularly relate to a kind of airplane pod suspension cable overload shutoff device.
Background technology
When the trailing type gondola that fixed wing aircraft uses hanger rope longer, and under the situation that during work, flying height distance ground is nearer, be wound around or generation analogue by high tension cord or trees, by very possible entail dangers to flight safety once gondola or hanger rope.
Summary of the invention
The technical problem to be solved in the present invention: design a kind of airplane pod suspension cable overload shutoff device, automatically cuts off gondola hanger rope where necessary, abandons gondola.
Technical scheme of the present invention: a kind of airplane pod suspension cable overload shutoff device, hanger rope fixed bearing is fixed on housing, and hanger rope is through the groove on hanger rope fixed bearing, and hanger rope is stuck on hanger rope fixed bearing by blanking cover, and cutter head is fixed on tension arm; Hanger rope is contained in the fork ear of tension arm, being installed with being bolted to of track adjusting wheel pitches on ear, spring and tension arm are successively through on the guide rod of spring bearing, spring bearing is fixed on housing, tool rest is installed on hanger rope fixed bearing, 4 positioning guide pulleys are arranged on the side in housing hanger rope path, and safety pin is inserted into by the hole on cap in the groove on blanking cover.
Beneficial effect of the present invention: design a kind of airplane pod suspension cable overload shutoff device, automatically cuts off gondola hanger rope where necessary, abandons gondola, ensures the flight safety of aircraft.
Accompanying drawing explanation
Fig. 1 is airplane pod suspension cable overload shutoff device shaft side figure (cap is not shown).
Fig. 2 is airplane pod suspension cable overload shutoff device component drawings (cap is not shown).
Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, service condition of the present invention is described:
First according to Fig. 2, airplane pod suspension cable overload shutoff device assembly is installed.First hanger rope fixed bearing 3 is fixed on housing 8, hanger rope 5 is installed blanking cover 6 through after the groove on fixed bearing, prevents hanger rope from deviating from.Be fixed on by cutter head 7 on tension arm 10,4 nuts 9 mainly play a part fixing and locking.Hanger rope 5 is contained in the fork ear of tension arm 10, then pitches being installed with being bolted to of track adjusting wheel 4 on ear.Successively by spring 11 and tension arm 10 on the guide rod through spring bearing 12, again spring bearing 12 is fixed on housing 8, tool rest 2 is installed on hanger rope fixed bearing 3,4 remaining track adjusting wheels are installed to the side in housing 8 hanger rope path, be used for carrying out spacing to hanger rope, cover cap (not shown), and safety pin 1 is inserted in the groove on blanking cover 6 by the hole on cap.Safety pin 1 is for preventing hanger rope from being cut off by mistake, when hanger rope works, must extract safety pin.
When being cut off by hanger rope, the requirement of suffered pulling force calculates the deflection (by testing the relative position relation list by the numerical value of pulling tension requirements and cutter head, to inquire about) that critical conditions spring 11 produces, and cutter head 7 is adjusted to relevant position.
During initial condition, gondola is not put down, and hanger rope 5 is in the state of not stressing, and pulled out an angle by tension arm, now spring 11 is without distortion.After gondola is put down, due to gravity and the air resistance of gondola itself, hanger rope is made to be subject to a pulling force.Under the effect of this pulling force, hanger rope drives tension arm 10 to move, and Compress Spring 11, tension arm 10 moves after a segment distance, and the pressure of spring is equal with the power that hanger rope produces tension arm 10, and this device is in state of equilibrium.When flight status changes, trickle change is made to make adjustments in the position of spring thereupon automatically.
When gondola or hanger rope are tangled because of unforeseen circumstances, the pulling force of hanger rope increases, and drives tension arm 10 to move further, continues Compress Spring 11.When pulling force reaches default value, be fixed on tension arm 10 and just move to hanger rope edge with the cutter head 7 of its motion, once pulling force continues to increase, under cutter head 7 with the effect of tool rest 2, hanger rope is cut off.
Effect of the present invention is: 1) provide a kind of gondola hanger rope to cut off mode; 2) relatively little installing space; 3) manufacture, assembly technology is simple; 4) working service is convenient, cost is low.
