Electromagnetically-triggered friction type pressing and releasing device

Abstract

The invention provides an electromagnetically-triggered friction type pressing and releasing device. The device comprises a triggering mechanism, two drag hooks, a locking mechanism, an upper pressingplate, two triggers, two torsional springs, two tension springs, a lower pressing plate and a mounting base. The trigger mechanism is installed at the top of the mounting base, the upper pressing plate, the triggers, the torsion springs, the tension springs and the lower pressing plate are all arranged in the mounting base, the locking mechanism penetrates through the left side and the right sideof the mounting base, and the two drag hooks are connected with the left end and the right end of the locking mechanism respectively. In a locking state, the triggering mechanism limits the two triggers to rotate, the tension springs tension the triggers, the triggers are pressed on the upper pressing plate to press the locking mechanism, and the two drag hooks are locked; in an unlocking state,the trigger mechanism acts to unlock the two triggers, the torsion springs drive the triggers to rotate, the tension springs are separated from the triggers, pressing of the triggers on the upper pressing plate is relieved, the locking mechanism is released, and the two drag hooks are separated. The device has advantages of a large bearing capacity, quick action, repeatable testing and insensitivity to a high temperature and a low temperature, and the device can be applied to various connection and separation occasions.

Description

technical field [0001] The invention belongs to the technical field of compression release devices, in particular to an electromagnetically triggered friction type compression release device. Background technique [0002] With the development of aerospace, aviation, and navigation technologies, the development and application of technologies such as space environment detection, astronomical observation, ocean exploration, space science experiments, and high-altitude target detection has become an urgent need. The function of the compression release device is to ensure reliable locking between the load and the release platform, or between the load and the load during the launch or operation of the equipment; when the system issues a release command, the load can be quickly realized from the release platform. , or the loads are separated from each other. Although the traditional pyrotechnic trigger method is reliable in separation and has a short actuation time, it often has ...

AI Technical Summary

Problems solved by technology

Although the traditional pyrotechnic trigger method is reliable in separation and short in action time, it often has a large impact and is not repeatable. After triggering, a lot of harmful gas is generated, and the attached ignition system is not conducive to the miniaturization of the device.

Nowadays, many non-pyrotechnic compression release devices have partially overcome the shortcomings of pyrotechnic triggering, but they have brought new problems, such as long actuation time, heat sensitivity, complex mechanism, large space occupation, small load, etc.
