Abstract

FIELD: space engineering.

SUBSTANCE: device comprises drive pivotally mounted on the base, balancing device, and boom. The boom is pivotally connected with the detachable joint through a tie and with the tie through the vertical and horizontal telescopic arresters. The horizontal telescopic arrester has cylinder, rod and shock absorber mounted inside cylinder, and ball lock mounted on the cylinder. The ball lock cooperates with the rod. The shock absorber is made of a stack of inner and outer rings having the same thickness and outer and inner conical surfaces. The rings bear one against the other. The vertical telescopic arrester has rod with the thrust and is provided with the spring-loaded lock that cooperates with the thrust.

Description

The proposed device relates to the field of launch equipment for space rockets, and in particular to devices for diverting communications with airborne detachable connections from the rocket.

A device for the removal of electrical connectors for communications A. with. No. 54614 dated January 12, 1970, containing a base, a drive carriage mounted on the rollers in the guide grooves, a latch, a shock absorber, a traction connected to the connector, a spring-loaded roller in contact with the copy element.

The disadvantage of this device is the possibility of collision of detachable connection with the elements of the cable-refueling tower during the withdrawal until the carbon part of the thrust to the roller sinks.

In part, this drawback was eliminated in the retraction device according to patent No. 2144464 dated January 10, 1999 (prototype) in that a telescopic limiter was introduced therein.

The disadvantages of this device are:

1. Large dynamic loads on the tap.

2. A large gas-dynamic effect on the exhaust device due to leakage of the gas stream from the working engines when the rocket is launched into the gap between the protective peak of the cable-filling tower and the detachable connection after the exhaust.

These disadvantages are eliminated in the proposed device by the addition of a horizontal telescopic limiter, one end pivotally connected to the boom, and the other end - with a rod, consisting of a cylinder, rod, shock absorber, made of a set of internal and external conical rings of the same thickness, supported by conical surfaces on top of each other, and a ball lock interacting with the limiter rod, and the vertical telescopic limiter is equipped with a spring-loaded latch interacting with emphasis made on the limiter rod.

Thus, in the proposed device due to the restriction of the movements of the detachable connection during braking and when discarded from the cable-filling tower during the withdrawal process, they are significantly reduced:

1. Dynamic loads on the tap.

2. The gas-dynamic effect on the exhaust device by reducing the gap between the protective visor and the detachable connection in the retracted position.

Collisions of the detachable connection with the side during retraction are excluded.

The drawings show:

view A, the allotted position of the device - figure 2;

A communication tap with a detachable connection consists of a base 1 (Fig. 1), on which, with the help of the axes, a boom 2, a drive 3, a balancing device 4, a rod 5 are pivotally connected at one end with an arrow 2 and the other end with a detachable connection 6.

A telescopic limiter 7 is installed on the boom 2, designed to absorb the reject energy of the detachable connection 6 with communications 8 from the cable-filling tower 9 and fixing them in the extreme lateral position.

The limiter 7 consists of a cylinder 10 (Fig. 4), inside which a set of outer rings 11, a set of inner rings 12, a rod 13 connected through a spherical hinge with an arrow 2 (Fig. 1), a rod 14 (Fig. 4) connected through a double hinge with a thrust 5 (figure 1), which through the guide 15 (figure 4) interacts with a ball lock mounted on the cylinder 10.

The ball lock consists of a spring-loaded cage 16, balls 17 and a spring-loaded sleeve 18.

The telescopic limiter 19 (Fig. 1), mounted through a double hinge on the boom 2, is designed to limit the movement of the detachable connection 6 with communications 8 downward after separation from the side and fixing them in this position and consists of a cylinder 20 (Fig. 3), in which, through the supporting guide 21, a rod 22 is installed with a piston 23, connected through a double hinge with a rod 5 (Fig. 1), is installed through a disk spring 24 (Fig. 3), a rod 25 with a piston 26, connected with an arrow 2 (Fig. 1) installed spring-loaded latch 27 (figure 3), interacting with the stop ohm 28 mounted on the stem 22.

The supply of moving parts with communications to the board 29 (Fig.1) is carried out by the drive 3.

After the supply, the rod 5, shock absorbers 30 and communications 8 are connected to the detachable connection 6.

When the side fluctuates relative to the cable-filling tower 9, the hinged connections of the device elements provide free tracking of the mutual movements of the side and the cable-filling tower.

After undocking the detachable connection 6 from the side 29, the actuator 3 retracts the boom 2 with a detachable connection and with communications in the designated position.

In this case, the detachable connection with communications under the influence of its own weight falls down to the stop of the shoulder of the rod 22 (Fig. 3) with the stop 28 in the support guide 21, and the rod 22 is fixed to the stop 28 by a spring-loaded latch 27, and the detachable connection with the communications is thrown away from cable-refueling tower 9 (Fig. 1) to a position where the balls 17 (Fig. 4) under the action of a spring-loaded clip 16 fall into the groove G of the guide 15 and the rod 14 is locked, and the reject energy is suppressed by the fact that the outer conical surfaces of the inner rings 12 pe emeschayutsya inner conical surfaces of the outer rings 11, i.e., the rings partially enter each other, overcoming the frictional forces, while the outer rings are stretched, and the inner ones are compressed, giving a draft.

Thus, the ball lock is detachable with communications on the rod 14 of the telescopic limiter 7 (Fig. 1) in the horizontal plane and the spring-loaded latch 27 (figure 3) on the rod 22 of the telescopic limiter 19 (Fig. 1) in the vertical plane, thereby eliminating the rebound of the detachable connection with communications upward when braking by the hydrobuffer of the balancing device 4 at the end of the outlet, which significantly reduced the gap D (Fig. 2) between the protective peak 31 and the detachable connection 6.
