Abstract
Description
Technical Field
[0001] The invention relates to a pulling mechanism for a rocket electrical disconnecting connector, which is a dragging and pulling mechanism in the application field of rocket cable disconnection on a rocket launch platform. Background Art
[0002] Currently, during rocket launches, the rocket's electric disconnect connector is disconnected by dragging it with a rope. When the rocket rises to a certain height, the rocket's electric disconnect connector is disconnected from the rocket under the action of the pulling rope. After disconnection, it is only affected by the pulling rope, and the pulling rope has a certain length. Due to the rocket's jet flame, negative pressure is generated around the containment release device / support device at the end of the rocket, causing the electric disconnect connector installed on the containment release device / support device to fly toward the rocket's bottom nozzle under the action of negative pressure after disconnecting from the rocket body, causing it to collide with the rocket nozzle. Based on the functional requirements of the rocket's electric disconnect connector, a pulling mechanism for the rocket's electric disconnect connector is proposed. The mechanism mainly integrates a locking and unlocking mechanism and a pulling mechanism. The locking and unlocking mechanism is unlocked by using the pulling force of the rocket's takeoff, thereby completing the pulling limit of the electric disconnect connector by the pulling mechanism. Summary of the Invention
[0003] The technical problem solved by the present invention is: solving the problem that the position of the rocket electric disconnect connector cannot be controlled after it is disconnected, and avoiding the collision of the rocket electric disconnect connector with the rocket nozzle after it is disconnected.
[0004] The technical solution of the present invention is: before the rocket takes off, the restraining load is constrained by a locking and unlocking mechanism. When the rocket takes off and the electric disconnect connector is detached at a certain height, the locking and unlocking mechanism is unlocked to release the restraining load to achieve pulling and limiting of the electric disconnect connector.
[0005] The beneficial effects of the present invention compared with the prior art are:
[0006] (1) The present invention utilizes a locking and unlocking mechanism to constrain the restraining load before the electrical disconnect connector is disengaged.
[0007] (2) The present invention utilizes a restraining load to pull and limit the electrically disconnectable connector after it is disconnected.
[0008] (3) The pulling mechanism of the rocket electric disconnecting connector of the present invention has good unfolding, locking and unlocking performance, light weight and reliable pulling. The mechanism is mainly used as a pulling limit for the disconnecting connector on the launch platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The rocket end (1) is shown to be mounted on the restraining release device base (19), and the cable removal connector (2) is mounted on the connector of the rocket end (1); the pulling rope at the tail end of the cable removal connector (2) passes through the limit hole at the upper end of the removal limit seat (5) and is fixed to the main base (16); the protective cover (7) is mounted on the pulling load seat (18); the unlocking ball (6) is mounted in the guide groove of the unlocking mechanism seat (13), one end of the unlocking rope (4) is fixed to the cable removal connector (2), and the other end is connected to the unlocking ball (6).
[0017] Figure 1 The spring limiting shaft A (9) is shown to be mounted on the unlocking lever (8), and the unlocking lever (8) is mounted on the unlocking mechanism seat (13) through the unlocking lever shaft (12); the spring limiting shaft B (11) is also mounted on the unlocking mechanism seat (13); one end of the spring (10) is mounted on the spring limiting shaft A (9), and the other end is mounted on the spring limiting shaft B (11).
[0018] Figure 1 The figure shows that the limiting guide rod shaft (14) is installed on the unlocking rod (8), and the limiting guide rod (15) is installed on the limiting guide rod shaft (14).
[0019] Figure 1 The figure shows that the main base (16) is mounted on the restraining release device base (19), and the pulling load base (18) is mounted on the main base (16).
[0020] Figure 1The pulling load (17) is shown to be installed in the slide groove of the pulling load seat (18) and connected to the load pulling rope (3). The other end of the load pulling rope (3) is fixed on the cable removal connector (2).
[0021] Figure 2 The figure shows the situation before the rocket takes off: the pulling rope at the tail end of the cable pull-out connector (2) passes through the limit hole at the upper end of the pull-out limit seat (5), and a certain margin is left to ensure that the rope is in a tension-free state, and that the pulling rope at the tail end and the fixed point do not interfere with the hole of the pull-out limit seat (5) after being straightened.
[0022] Figure 2 The figure shows the rocket before takeoff: one end of the load pulling rope (3) is fixed to the cable removal connector (2), and the other end is fixed to the pulling load (17), with a certain margin to ensure that the rope is in a tension-free state.
[0023] Figure 2 The figure shows the rocket before takeoff: one end of the unlocking rope (4) is fixed to the cable removal connector (2), and the other end is connected to the unlocking ball (6), with a certain margin to ensure that the rope is in a tension-free state; the unlocking ball (6) is located in the guide groove of the unlocking mechanism seat (13) and is pressed by the upper end of the unlocking rod (8) under the action of the spring (10).
