Detailed Description
The invention mainly realizes the separation of the airdrop piece and the parachute at the landing moment of the airdrop system, and prevents the parachute from continuously fully dragging the airdrop piece under the condition of wind on the ground after the airdrop piece lands.
The invention mainly applies small pulling force to the two ends of the release lock at the moment of landing of the air-drop system, the bayonet lock is pushed out of the locking position by the spring, and the ejector rod separates two force arms under the action of the spring, so that the separation of the air-drop piece and the parachute is realized.
The invention comprises a y-shaped force arm, an r-shaped force arm, a bayonet lock with a spring plate, two side plates with the same structure, a motor, a screw rod, a stop block, a gear set, a push rod, a screw sleeve and a stop plate.
The y-shaped arm of force and the r-shaped arm of force are connected with two side plates with the same structure at the bifurcation of the right side of the y through rivets, one end of each side plate with the same structure is riveted, the other end of each side plate is provided with a round hole, and the round holes are connected with the parachute through bolts and nuts. The left fork of the y-shaped arm is split with a round slot, and the round slot is screwed into the screw sleeve for fixation after being provided with a spring and a push rod. The arm of force similar to circular arc is provided with a straight slot outside the disengaging lock, and is sequentially provided with a motor, a gear set, a screw rod, a stop block and a stop plate from top to bottom. The bayonet lock equipped with the shell fragment is riveted at the lower extreme of "y" type arm of force.
When the assembled release lock is used, the parachute is connected with the two side plates through bolts, and the air drop piece is connected to the clamping pin provided with the spring piece. The two force arms can rotate around the rivet, the ejector rod is compressed when the two force arms are clamped, when the two ends of the lock are separated and stressed simultaneously, the bayonet lock provided with the elastic sheet is clamped into the lower end of the arc-shaped force arm, when the air drop piece falls to the ground, the tension at the two ends of the separation lock is reduced, the ejector rod ejects the two force arms under the action of the spring, and the bayonet lock is separated from the air drop piece.
The invention is further described below with reference to the drawings and examples.
As shown in fig. 1, the disengaging lock comprises two identical side plates 1, an r-shaped force arm 2, a screw 3, a stop block 4, a stop plate 5, a spring plate 6, a bayonet 7, a push rod 8, a screw sleeve 9 and a y-shaped force arm 10.
The y-shaped force arm 10 (figure 1) is respectively grooved at three ends, the groove 1 is matched with one end of the r-shaped force arm 2 with a round hole, after the round holes are aligned, the left side plate and the right side plate are riveted together, and the two force arms and the side plates can rotate around rivets. The other ends of the two side plates 1 are provided with round holes which are connected with the parachute through a bolt structure. The slot 3 of the y-shaped arm 10 is riveted with the end with the round hole of the bayonet 7 provided with the spring 6, and the bayonet 7 can rotate around the rivet (figure 2). The groove 2 is a round groove, the notch is provided with a thread structure, the spring and the ejector rod 8 are sequentially put into the threaded sleeve 9 for fixing the ejector rod 8, and the ejector rod 8 can move due to the spring (figure 1).
The "r" arm 2 structure (fig. 3) is relatively complex, providing mounting locations for many structural members in addition to being a load bearing member. The r-shaped force arm 2 is provided with a rectangular groove III and a round groove IV in sequence from top to bottom near the upper end, the other side corresponding to the round groove IV is provided with a rectangular groove II, two faces perpendicular to the working face where the round groove IV is positioned are respectively provided with a long groove I and a rectangular groove V, the long groove I starts from the uppermost end of the r-shaped force arm 2 until the vicinity of the bottom end is not penetrated, the rectangular groove V corresponds to and penetrates through the long groove I, and the interior of the long groove I is provided with a groove VI.
The first long groove is a motor, a gear set, a screw rod 3, a stop block 4, a stop plate 5 and two spring mounting positions, the motor is in threaded connection with the gear set, the screw rod 3 and the gear set are of a gear-thread transmission structure, the stop block 4 is a cuboid, a threaded hole is formed in the center of the stop block, and the stop block is screwed into the screw rod 3. The screw 3 rotates under the action of the motor, and the first long groove prevents the stop block 4 from rotating along with the rotation, so that the stop block 4 moves along the first long groove. The stop plate 5 approximates to a rectangular thin plate, after the spring is installed in the groove six, the spring is riveted in the groove one, and one end of the stop plate 5 is positioned above the groove six, so that the tilting plate movement can be realized around the rivet; after the installation of the parts in the first long groove is completed, an aluminum sheet is covered above the working surface of the first long groove, and the thread structure is fixed;
The rectangular groove II is a ship-shaped switch installation position; the rectangular groove III is a blocking switch mounting position; the round groove IV is a battery mounting position; the rectangular groove V is a locking position of the bayonet lock provided with the spring plate, and is communicated with the long groove I; the groove six is the installation position of the stop plate spring. The slots for mounting electronic components are all machined with small holes for wire mounting.
With reference to fig. 5, the main working procedure of the disengaging lock is as follows:
1) The two clamping plates of the disengaging lock are connected with the parachute through bolts, and the clamping pin is connected with the air drop piece.
2) Locking state: when the two arms are clamped, the ejector rod is compressed, the bayonet lock riveted with the elastic piece is inserted into the clamping groove (groove five) corresponding to the r-shaped arm of force, tension is applied to the two ends of the disengaging lock under the condition that the two arms are clamped, the spring below the bayonet lock and the elastic piece are compressed simultaneously, the stop plate is pressed down and clamped into the step of the bayonet lock at the moment, then the ship-shaped switch is pressed down, the motor works to push the stop block below the stop plate until the circuit breaker switch (figure 4) is triggered, the motor stops working, the circuit breaker pin is inserted into the blocking switch, and the ship-shaped switch is stirred to the other end, and the disengaging lock is in a locking state at the moment.
3) Air drop state: after the air drop piece leaves the machine, the parachute is opened and the breaking pin is pulled out, the motor reversely rotates, the stop block is moved out of the lower part of the stop plate, the stop plate is tilted under the action of the spring, and at the moment, the stop plate is not contacted with the step at the end of the bayonet lock any more, and the locking is released. When the stop block moves upwards to a certain position, a circuit breaker is triggered (in fig. 4, insulating protrusions are adhered to two ends of the fixed block, and a metal sheet can be jacked up in moving to achieve a circuit breaking effect), and the motor stops working. After the parachute is completely opened, the clamping pin compresses the spring below the clamping pin under the action of the tension of the air dropping piece. After the air drop piece lands, the bayonet lock is bounced, under the ejector rod effect. The two arms of force are sprung apart to separate the air drop piece from the parachute, and unlocking is completed.
Through the near 30 tests on the ground, the invention has good test process, and the unlocking is smooth at the moment that the tension forces at the two ends of the unlocking are disappeared, so that the faults such as unsmooth actuation, clamping stagnation and the like are avoided, and the expected effect is basically achieved.
The invention can change the opening time of the aerial insurance by replacing the gear set connected with the motor so as to adapt to different small air drop situations.
