Abstract
The invention relates to the design field of airplanes, and provides an airplane pod suspension cable overload cutting device. A suspension cable fixing support is fixed on a shell, a suspension cable penetrates through a groove formed in the suspension cable fixing support, a plug clamps the suspension cable on the suspension cable fixing support, and a cutter head is fixed on a pulling force arm. The suspension cable is arranged in a fork lug of the pulling force arm, a bolt which penetrates through a guide wheel is fixed on the fork lug, a spring and the pulling force arm sequentially penetrate through a guide rod of a spring support which is fixed on the shell, a cutter base is arranged on the suspension cable fixing support, four locating guide wheels are arranged beside a shell suspension cable route, and a safety pin is inserted in the groove of the plug through a hole formed in a shell cover. According to the airplane pod suspension cable overload cutting device, the pod suspension cable is automatically cut off as occasion requires, a pod is eliminated, and air safety of an airplane is guaranteed.
Description
Technical field
The present invention relates to airplane design field, relate in particular to a kind of aircraft gondola hanger rope overload shutoff device.
Background technology
When fixed wing aircraft uses the longer trailing type gondola of hanger rope, and flying height, under the nearer situation in ground, is wound around or analogue occurs by high tension cord or trees once gondola or hanger rope, by very possible entail dangers to flight safety during work.
Summary of the invention
The technical problem to be solved in the present invention: design a kind of aircraft gondola hanger rope overload shutoff device, automatically cut off where necessary gondola hanger rope, abandon gondola.
Technical scheme of the present invention: a kind of aircraft gondola hanger rope overload shutoff device, hanger rope fixed bearing is fixed on housing, and hanger rope is through the groove on hanger rope fixed bearing, and blanking cover is stuck in hanger rope on hanger rope fixed bearing, and cutter head is fixed on tension arm; Hanger rope is contained in the fork ear of tension arm, be installed with being bolted on fork ear of track adjusting wheel, spring and tension arm are successively on the guide rod through 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 in the groove on blanking cover by the hole on cap.
Beneficial effect of the present invention: design a kind of aircraft gondola hanger rope overload shutoff device, automatically cut off where necessary gondola hanger rope, abandon gondola, ensure the flight safety of aircraft.
Accompanying drawing explanation
Fig. 1 is aircraft gondola hanger rope overload shutoff device shaft side figure (cap is not shown).
Fig. 2 is aircraft gondola hanger rope overload shutoff device component drawings (cap is not shown).
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2, service condition of the present invention is described:
First according to Fig. 2, aircraft gondola hanger rope overload shutoff device assembly is installed.First hanger rope fixed bearing 3 is fixed on housing 8, hanger rope 5 is installed to blanking cover 6 after through the groove on fixed bearing, prevent that hanger rope from deviating from.Cutter head 7 is fixed on tension arm 10, and 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 on ear being installed with being bolted to of track adjusting wheel 4.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 paths, be used for hanger rope to carry out spacing, cover cap (not shown), and safety pin 1 is inserted in the groove on blanking cover 2 by the hole on cap.Safety pin 1 is for prevent that hanger rope from being cut off by mistake, when hanger rope is worked, must extract safety pin.
While cutting off by hanger rope, the requirement of suffered pulling force calculates the deflection (numerical value that can pulling force be required by test and the relative position relation list of cutter head, so that inquiry) 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, in the state of not stressing, is pulled out an angle by tension arm, and now spring 11 is without distortion.After gondola is put down, due to gravity and the air resistance of gondola itself, make hanger rope be subject to a pulling force.Under the effect of this pulling force, hanger rope drives tension arm 10 motions, Compress Spring 11, and after tension arm 10 motion one segment distances, the pressure of spring equates the power of tension arm 10 generations with hanger rope, this installs in state of equilibrium.When flight status changes, trickle variation 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 further move, continuation Compress Spring 11.When pulling force reaches default value, be fixed on the cutter head 7 with its motion on tension arm 10 and just move to hanger rope edge, once pulling force continues to increase, under the effect of cutter head 7 and 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.
Claims (1)
1. an aircraft gondola hanger rope overload shutoff device, is characterized in that, hanger rope fixed bearing is fixed on housing, and hanger rope is through the groove on hanger rope fixed bearing, and blanking cover is stuck in hanger rope on hanger rope fixed bearing, and cutter head is fixed on tension arm; Hanger rope is contained in the fork ear of tension arm, be installed with being bolted on fork ear of track adjusting wheel, spring and tension arm are successively on the guide rod through 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 in the groove on blanking cover by the hole on cap.
