Description

 The invention relates to devices for removing communications with detachable connections from the side (for example, rockets, ships, etc.) and can be used in launch complexes of space rockets, as well as in units for transporting fluid from a berth to a ship.

 A device for diverting liquid communications with a detachable connection from the side of the vessel, for example, a device for transporting liquid with a power balancing system according to US patent N 3.581.769 from 06/01/1971, containing a base, a rotary stand, a counterweight with a cable system, hydraulic cylinders.

 The disadvantages of this device are the large masses of the balancing device, which create increased dynamic loads on board during the oscillations of the latter, as well as the use of a pipeline under pressure as a power supporting element of the device.

 Partially, these disadvantages are eliminated in the device according to US patent N 3.805.834 from 04/23/1974 (prototype) by the fact that it introduced a power bearing boom.

The disadvantages of this device are:
1. Large dynamic loads on board when tracking the fluctuations of the latter in the vertical plane due to the multiple increase in the mass of the device due to the mass of the balances

 2. Large dynamic loads on board when tracking the fluctuations of the latter in the horizontal plane due to the rotation of the entire device in the horizontal direction during tracking.

 3. The presence of a large number of drives that control the movement of the elements of the device, suggesting a complex system of control and management.

 4. The lack of stabilization and fixation in a certain stable position of the end element of the pipeline with a detachable connection when diverting from the side, which can lead to their collision with the latter.

 5. The use of a rigid pipeline with a large number of complex swivel joints that increase the hydraulic resistance to pumping fluid.

 6. Operational inconvenience, which consists in the fact that when replacing or repairing sections or individual joints of the pipeline, it is necessary to dismantle the balances and other elements of the entire device.

 7. The difficulty of placing multiple pipelines when using a multi-channel on-board detachable connection.

 These disadvantages are eliminated in the proposed device by the fact that the balancing device is made in the form of a spring suspension with springs located between the movable brackets on parallel guides, and between the springs there is a hydrobuffer, the spindle of which is connected via an axis to one of the movable support brackets and the cylinder to the other a movable support bracket, a rod connecting the arrow with a detachable connection and a telescopic limiter, the lower articulation of which is articulated, are mounted on the boom horizontally offset from the axis of the device and an upper end pivotally connected to the rod, which further is pivotally connected to the releasable connection through the shock absorbers, and a drive rod mounted spring loaded sleeve, cooperating with the cylinder.

Thus, in the proposed device:
1. Its total mass and dynamic load on board are significantly reduced due to the implementation of the balancing device in the form of a spring suspension and the use of articulated traction to track the horizontal movements of the side in the process of pumping fluid.

 2. The use of one drive to control the movement of the boom instead of several in the device prototype involves a significant simplification of the control system and their management.

 3. The presence of stabilization and fixation in a certain stable position of the end element of the pipeline with a detachable connection when diverting from the side excludes their collision with the latter.

 4. The hinged rod support system, consisting of an arrow and traction, allows the use of a shorter refueling communication (pipeline), reducing its weight and hydraulic losses during pumping.

 5. Replacement or repair of communication can be carried out without dismantling the elements of the device.

 6. It is possible to place several pipelines when using a multi-channel side connector.

 A communications outlet device with a detachable connection consists of a base 1 (Fig. 1), welded from channels, on which an arrow 2, an actuator 3, a balancing device 4, are designed to hang the movable parts of the outlet device with communications 5 fixed to the arrow 2, which consists of two packages of springs 6 (Fig. 2) mounted on guides 7 and located between the upper movable support bracket 8 and the lower movable support bracket 9, which is connected via an axis to the spindle 10 of the hydrobe EPA, and the cylinder 11 through the rod 12 with the arrow axis 13 of the coupled 2 (FIG. 1).

 The guides 7 (Fig. 2) are fixedly mounted on the bracket 14.

 The upper end of the boom 2 (Fig. 1) is connected through a double hinge with a rod 15, which is pivotally connected to a detachable connection 16.

 On the boom 2, a telescopic limiter 17 is installed through a double hinge, designed to limit the movement of the detachable connection to communications 5 after separation from the side.

 The limiter consists of a cylinder 18 (Fig. 4), in which a rod 20 with a piston 21, connected via a double hinge with a rod 15 (Fig. 3), is installed through a cup spring 22 (Fig. 4), the rod 23 s a piston 24 connected to the boom 2 (Fig. 3).

 Shock absorbers 25 are installed on the link 15 for damping the vibrations of the detachable connection 16 (Fig. 1) with communications 5 when they are retracted, which consist of a cylinder 26 (Fig. 5), in which there are bushings 27 that absorb the vibrations of the detachable connection through washers 28 and 29, the stem 30 with the piston 31, connected through a spherical hinge 32 with a detachable connection 16 (Fig. 1), a guide 33 (Fig. 5), an earring 34, connected through a spherical hinge 35 with a rod 15 (Fig. 1) .

 The actuator 3 consists of a cylinder 36 (Fig. 6), in which a rod 37 with a piston 38, a guide 39 is placed. A sleeve 40, a spring 41 are mounted on the rod. The rod 37 is connected to the arrow 2 using the axis 42 (Fig. 1).

 Compressed gas is supplied to the cylinder through line 43 (FIG. 6).

 The supply of moving parts with communications to the board 44 is carried out by the drive 3. After the supply, the rod 15, the shock absorbers 25 (Fig. 1) and the communications to the detachable connection 16 are connected, the swivel joints of the device elements provide free tracking (Fig. 1).

 When the side fluctuations relative to the service site 45, the swivel joints of the device elements provide free tracking of the device for plane-parallel and angular side vibrations in horizontal and vertical planes.

 After undocking the detachable connection 16 from the side 44, the actuator 3 together with the springs of the balancing device 4 retracts the boom 2 with the detachable connection 16 and communications 5 to the retracted position.

 In this case, the detachable connection with communications under the influence of its own weight is lowered down to the stop of the bead A (Fig. 4) of the rod 20 in the support guide 19 and is thrown to the side opposite to the displacement of the hinge of the limiter from the axis of the device to the position limited by the cable 46 (Fig. 3 )

 The lower movable support bracket 9 (Fig. 2) with spindle 10 reaches the stop B, and the upper movable bracket 8 with cylinder 11 after approaching the collar B begins to move along the guides 7, compressing the springs 6. In this case, the kinetic energy of the moving parts is damped tap devices.

 When the cylinder is moved relative to the spindle, the area of the slit for fluid flow decreases.

 The sleeve 40 (Fig. 6) after stop in the guide 39 stops, and the rod 37, moving, compresses the spring 41.

 Thus, the braking of the moving parts of the device at the end of the retraction occurs.

 The return of the detachable connection with the communications to the storage position after the drainage of gases from the cavity of the pneumatic cylinder 6 occurs under the action of the spring 41 and the springs 6 (Fig. 2).

 The movement of the moving parts of the device occurs until the stop of the upper movable thrust bracket 8 in the shoulder B.

The implementation of the balancing device in the form of a spring suspension, the presence of a hydrobuffer, articulated traction connecting the boom with a detachable connection, a telescopic limiter, the lower articulated connection with the boom is offset from the axis of the device, shock absorbers and a spring-loaded sleeve on the actuator rod provides
a significant reduction in the total mass of the device and a reduction in the load on board;
simplification of the control system and device management;
the exception of the collision of the detachable connection with the side during the tap;
