Description
Technical Field
The invention relates to the technical field of stripping devices, in particular to a stripping device for a recyclable rocket and an installation method.
Background
The separated electric connector (off-plug) is an electric connector between the rocket and the ground, the off-plug socket is generally arranged at the tail end of the rocket and is a connection interface between ground electricity and the rocket, and the off-plug socket is separated from the plug before the rocket takes off. The reliable pulling-out force is between F+/-DeltaF, and the included angle between the pulling force direction and the axis of the pull rod is generally required to be not more than 10 degrees.
The upper end of the pulling-out device is connected with a small section of steel wire rope ring of the plug pulling-out pull rod, or is connected with a round hole of the plug pulling-out pull rod through an S-shaped hook, and the lower end of the pulling-out device is fixedly connected to the ground, or is fixedly connected to a launching table (or a launching frame), and mechanical separating force is provided for pulling-out and inserting separation during rocket take-off, so that pulling-out and taking-off separation is realized, and the pulling-out device is a device for providing separating force for pulling-out and inserting separation. The dead weight of the pulling-out device before the rocket take-off is required to be far smaller than the minimum pulling-out force F-DeltaF of the socket so as to avoid the failure of rocket launching tasks caused by the premature falling-out of the socket, and the minimum strength of the pulling-out device is required to be larger than the maximum pulling-out force F+DeltaF of the socket so as to ensure that the pulling-out force is available.
Conventionally, the main component of the stripping device of the disposable carrier rocket (or missile warhead) is a steel wire rope, the upper end of the stripping device is connected with a plug which is stripped, and the lower end of the stripping device is fixedly connected with a launching pad, and the length of the stripping device is generally not more than 1m. The length adjustment range of the steel wire rope is generally +/-10 mm, so that the required loosening amount of the plug is met. The launching pad accessory is provided with a transverse displacement adjusting device so as to adapt to the position error of the plug on the rocket. On the day of the firing, the fire-proof material is used for heat protection on site after installation.
The upper end of the pulling-out device is connected to the pull-out rod of the pulling-out socket from the strip steel rope ring or the S-shaped hook, and the lower end is connected to the transmitting table or the transmitting frame. The general scheme of pulling out the device has 2 kinds in the tradition, and 1 st kind main component is wire rope, uses wire rope clamp according to the demand of connecting length, presss from both sides wire rope at the transmission scene, adjusts clamping position and can adjust wire rope length, and this kind of scheme's advantage is that length adjustment is convenient, and adjustment range is very big. The disadvantage is that the clamping operation relies on the experience of the worker, the clamping degree is difficult to quantify, and the connection strength of the steel wire rope is not measured. If the wire rope clip slides or loosens, the maximum pulling force F+DeltaF required by the falling plug may not be reached, and the falling plug may not separate, resulting in failure of the rocket launching task.
