Abstract

FIELD: pipeline transport, particularly devices used in space launcher complexes and in liquid and gaseous medium transportation equipment.

SUBSTANCE: device comprises joint with fitted service lines pivotally connected to carriage moved by pneumatic cylinder. Connected to the joint are pins and gripping means. Joint cap is made as cylinder with flange and is fixedly installed in protective structure so that the joint cap is coaxial to the gripping means in its initial position and is provided with bushes. The bushes and the flange may cooperate with the pins and the gripping means. Inner cap diameter is related to outer joint diameter so that closed space in created after joint connection with cap by displacing above pneumatic cylinder.

EFFECT: extended range of technical means.

Description

The invention relates to devices for protecting communications connectors of docking and removal mechanisms from environmental influences and can be used in space rocket launch complexes, as well as in units for transporting fluid and gaseous media.

Known automatic quick connection of pipelines according to copyright certificate No. 1257352, class. F 16 L 37/28, including a movable coupling half with an actuator in which a spring-loaded valve is installed, and a fixed coupling half that is joined with it, in which a spring-loaded hollow spool with a spring-loaded valve are installed, a support sleeve interacting with the spool sealing element, and a wiper sleeve .

The disadvantages of this device are that the end sections of the connected communication and the neck, made in the form of half-couplings with valves, are not protected from dust and dirt, which after joining may be in the communications. Also, the coupling halves increase the dimensions and, as a result, the mass of the end section of the connected communication and the neck, which creates increased dynamic loads on the neck both during docking and its fluctuations.

Partially, these shortcomings are eliminated in the device for protecting communications connectors from environmental influences according to copyright certificate No. 1234702, class. F 16 L 37/28 (prototype) in that it contains a connector, a plug made in the form of a rotary damper, and a plug drive with an elastic element in the form of a spring connected to one of the connector parts by one of the ends inserted to protect the end section interfaced communication from the impact of the external environment.

The disadvantages of this device are:

1. The increased end masses of the connected communication, which leads to an increase in the load on the neck and, as a result, the mass of the neck.

2. Complex kinematics of the rotary damper drive, which reduces the reliability of operation and increases the cost of manufacturing the device.

3. The presence on the neck of the stop acting on the actuator of the rotary damper, which increases the mass of the neck located on the rocket.

These disadvantages are eliminated in the proposed device by the fact that the plug of the connector is made in the form of a cylinder with a flange, is installed stationary in the protective structure coaxially with the connector in its original position and is equipped with bushings, while the bushings and flange are made to interact with the pins and grips of the connector, and the inner diameter of the plug is made relative to the outer diameter of the connector with the possibility of forming a closed space after the joint of the connector with the plug by the stroke of the pneumatic cylinder.

At the same time, common signs of the proposed device with the prototype are the presence of a connector with attached communications pivotally mounted on a carriage moved by a pneumatic cylinder, and plugs.

Thus, the proposed device:

1. Allows you to reduce the mass of the neck of the rocket, because there are no additional elements interacting with the rotary damper drive, as well as due to reduced loads due to a reduction in the end masses of the connected communications.

2. Simplifies the design, improves reliability, reduces manufacturing costs.

3. Allows you to reduce the pulling force of the communications connector and plugs in the storage position when using end sealing elements and increases their durability.

The drawings show:

figure 1 - docked position of the device with the neck of the rocket;

figure 2 - device with the neck of the rocket in the retracted position;

figure 3 - the position of the device in a protective structure;

figure 4 - the storage position of the device;

figure 5 is a section aa in figure 4.

The device consists of a base 1, on which racks 2 and 3 with rollers are fixed 4. On the rollers 4, the carriage 5 is mixed with the pneumatic cylinder 6.

Connector 7 with connected communications 8 is pivotally mounted through racks 9 on the carriage 5. Pins 10 and grips 11 are installed on connector 7. To fix the position of the base 1 on the rack 12, a latch consisting of levers 13 and 14 is fixed with axes.

On the rack 15, installed in the protective structure 16, the axes fixed to the pneumatic cylinder 17 to divert the device to the protective structure. The plug 18, mounted on the ceiling of the protective structure 16, has bushings 19 for orienting the connector 7 during docking and a flange 20 for fixing it in the docked position.

The balancing mechanism of the connector 7 are suspensions 21 pivotally mounted between the connector and the carriage. Connector 7 with communications connected to it is docked to the neck 22 of the rocket.

In the docked position with the neck 22 of the rocket, the carriage 5 is held by the grippers 11 of the connector 7. After opening the grippers 11 under the influence of the pneumatic cylinder 6, the connector 7 is undocked with the neck 22 and is withdrawn with the connected communications 8 to the designated position shown in FIG. 2. At the end of the retraction, the carriage 5, interacting with the levers 13 and 14, takes them out of the “dead center” and, under the influence of the pneumatic cylinder 17, the device retracts into the protective structure 16 to the position indicated in FIG. 3. To dock the connector 7 with the plug 18, a control pressure is supplied to the pneumatic cylinder 6, under the influence of which the connector 7, mounted on the carriage 5, moves to the plug 18, mounted on the ceiling of the protective structure 16, as shown in Fig.4. During the interaction of the pins 10 of the connector 7 with the bushings 19 of the plug 18, the orientation of the connector 7 is pivotally mounted through the posts 9 on the carriage 5, relative to the plug 18. At the end of the docking, the connector 7 is fixed with the plug 18 of the grippers 11, interacting with the flange 20, as shown in figure 5. In this case, a closed space 23 is formed after the connectors are plugged with a plug between the seals 24 and 25, which provides protection from the effects of the external environment, as shown in Fig. 5.

The docking of the connector 7 with the neck 22 of the rocket is carried out in the reverse order. All operations are carried out automatically without the presence of an operator.
