Description

The invention relates to mechanical engineering, and in particular to devices for retracting communications with a detachable connection from the side of the rocket, and can be used in launch rocket and space complexes.

A device for removing communications with a detachable connection according to the patent of Russia No. 2144464, IPC B65G 53/40.

The device consists of a rotary boom, a drive, a balancing device. The detachable connection includes an onboard board and a detachable unit.

The main disadvantage of the device is the manual connection of communications to a detachable unit, which does not allow automating the processes of docking and removal of communications.

Partially indicated disadvantages are eliminated in the tap-off device with detachable connection according to the Russian patent No. 2185315, IPC 7 B65G 53/40.

The device comprises a carriage equipped with a drive, a pipe with communications, equipped with a locking mechanism for the joint, and a balancing device. A detachable connection includes an onboard board of a space rocket (ILV) and a detachable unit. In the specified device provides automation of the processes of docking and removal of communications.

The disadvantage of this device is the lack of a certain fixed position of the communications in the docked, retracted position, which in the process of accelerated retraction can lead to unacceptable bends of communications and significant loads on the butt joint and the onboard releasable ILV connection.

Undocking and removal of the detachable unit with pipe and communications is carried out at the initial stage of the launch of the rocket launcher, while for the removal to a safe distance to the launch pad room, an accelerated mode of removal is necessary. In this regard, after undocking, an accelerated movement of the detachable unit with the pipe and communications and a significant shock loading of the moving parts and communications occur, while in the process of accelerated removal, the movement of communications is carried out according to the law of damped oscillations of a mechanical system with several degrees of freedom.

These disadvantages are eliminated in the proposed device by the fact that on flexible communications rigid adapters are provided, fixed with clamps in an arm pivotally mounted on a movable carriage, and the end sections of the adapters are made at an angle to each other.

Thus, in the proposed device:

- secured fixation of communications in the process of their accelerated retraction, while excluding their collision;

- provided spatial orientation of communications in the docked and allotted positions of the device;

- reduced load on the communications by changing the angle of inclination of the communications depending on the rigidity during the movement of the carriage;

- permissible bending radii of the communications are provided due to the rotation of the bracket with rigid adapters in the docked and allotted positions of the carriage, and also due to the introduction of clamps, the longitudinal position of the communications relative to the carriage is adjusted;

- reduced load on the nozzle and onboard detachable ILV connection due to the hinged mounting of the bracket with rigid communication adapters on the carriage.

The drawings show:

- figure 1 - placement of communications on the tap in the designated position;

- figure 2 - placement of communications on the device tap in the docked position;

- figure 3 - A (figure 1), B (figure 2);

- figure 4 - BB (figure 3).

A communications tap with a detachable connection consists of a pipe 1 (Fig. 1, 2) installed by means of a balancing device on the carriage 2. The carriage 2 is installed in the rollers 3, rigidly fixed to the side walls of the room in the supports of the launch pad (PS) 4, and is equipped drive 5, the rod of which is pivotally connected to the carriage 2, and the housing is pivotally connected to the support of the PS 4. The pipe 1 is equipped with guide pins 6 and grippers 7. Flexible communications 9 are attached to the pipe 1, on which rigid adapters 8 are installed (Figs. 3, 4 ) fixed in cro bracket 10 mounted on the axes 11 (figure 4). On the rigid adapters 8 (Figs. 3, 4) clamps 12 (Fig. 3) are placed for fastening and adjusting the longitudinal position of the communications 9. Onboard the rocket launcher 13 (Fig. 2) an onboard detachable connection is installed, including an onboard plate 14 and a detachable block 15. Communications 9 are laid in the slots of the bracket 10. In the initial position, the carriage 2 (Fig. 1) with the pipe 1 and communications 9 is in the allotted position. Communications docking operations are performed automatically. Compressed air is supplied into the union of the drive 5 to the carriage inlet. In the process of movement of the carriage 2, the bending radii and the configuration of the communications loop 9 change, which are compensated by the rotation of the bracket 10 in the axes 11 (Fig. 4), from the angle “a” (Figure 3) in the retracted position to the angle “b” in the docked position communications 9, after which the grips 7 (figure 2) are closed, providing the necessary force to seal the docked lines of the pipe 1 and the detachable unit 15. After that, the ILV is refilled. Undocking and withdrawal of communications are carried out at the initial stage of the ILV lift. Some time before the launch of the rocket engines, compressed air is supplied to the drive 5 of the carriage 2 in the direction of withdrawal, while undocking is not performed due to the fact that the detachable block 15 and the side plate 14 of the rocket launcher 13 are connected by a lock, and the nozzle 1 is locked relative to the detachable block 15 grippers 7. In this position, the device is in readiness for undocking, while the necessary gases continue to flow on board the ILV. After starting the rocket engines and starting the launch of the rocket launcher at a certain height of the lift, the pyromedia of the side plate 14 is triggered, the lock connecting the side plate 14 and the detachable block 15 with the pipe 1 and communications 9 opens, and the detachable block 15 with the pipe 1 and communications 9 move in accelerated mode in the direction of the retraction. In the process of movement of the carriage 2 there is a change in the bending radii of the communications 9 within the permissible limits due to the rotation of the bracket 10 in the axes 11 (figure 4) from the angle "b" (figure 3) to the angle "a". The fixed fastening of the rigid adapters 8 (Figs. 3, 4) on the carriage 2 (Figs. 1, 2) eliminates the mass of communications 9 in the section from the bracket 10 to the stationary pipelines of the PS 4, which reduces the loads transferred from the flexible communications 9 to the on-board detachable connection .

Thus, in the proposed device:

- the collision of mobile communications is excluded with the accelerated tap of the detachable block of the onboard detachable connection;

- reduced communication loads due to changes in the angle of inclination of rigid adapters fixed in the swivel bracket;

- permissible bending radii of communications are provided in the docked and allotted positions of the carriage due to the end sections of the rigid adapters made at an angle to each other;

- reduced load on the pipe and side detachable connection.
