Description

 The invention relates to devices for docking and removal of communications with detachable connections and can be used in launch complexes of space rockets, as well as in units for transporting fluid and gaseous media.

 A known connection device for a remote controlled flow line according to US patent N 4188050, class. 285-24, including two connecting elements, one of which is moved by means of hydraulic cylinders, and ball joints in one or both connecting elements to compensate for misalignment of pipelines.

 The disadvantages of this device is that the cones for the exact centering of the elements during the docking are made on interconnected communications, which increases the size and, as a result, the mass of its end section, creates increased dynamic loads on the neck when it fluctuates. Also, the increased dimensions make it practically impossible to use the device with large misalignment of interconnected communications (more than ± 50 mm).

 Partially, these disadvantages are eliminated in the device according to US patent N 4076361, CL. 339-113 (prototype) in that a remote manipulator is introduced in it to ensure centering of interconnected communications.

The disadvantages of this device are:
1. The inability to operate the device in automatic mode.

 2. The possibility of operator error is not ruled out, which reduces the reliability of the device and can lead to emergency situations.

 3. It is necessary to monitor the process of docking and removal using television equipment, which increases the cost of the device.

 4. The use of the manipulator complicates the device, reduces the reliability of its trouble-free operation, increases its cost.

 These disadvantages are eliminated in the proposed device by the fact that the drive is made in the form of two parallel mounted pre-supply pneumatic cylinders of the carriage and the docking pneumatic cylinder, and the orientation device is additionally equipped with a profile protrusion located on the neck and an adjustable spring stop mounted on the nozzle with the possibility of interaction with the mentioned profile protrusion .

Thus, the proposed device:
1. Allows you to work in automatic mode when connecting communications with large misalignment values, while the use of a manipulator is excluded.

 2. Increases the reliability of the device and eliminates the possibility of emergency situations due to the absence of the operator.

 3. Eliminates the need for monitoring the work using television technology, which reduces the cost of the device.

The drawings show:
retracted position of the device - FIG. 1;
the previously set position of the device - FIG. 2;
docked position of the device - FIG. 3;
section A, suspension - FIG. 4;
view B, view of the reciprocal neck - FIG. 5.

 The device consists of a base 1 (Fig. 1), on which the guides are fixed 2. The carriage 4 is moved along the guides on the rollers 3 by a drive made in the form of a pneumatic cylinder for the preliminary supply of the carriage 5 and a pneumatic cylinder of the docking 6, which are fixed by axes to the brackets 7 and 8 of the base 1 .

 The pipe 9 with attached communications 10 is pivotally mounted on the carriage by rods 11 with spring compensators 12. The pipe channels are closed by a cover 13, which opens with a pneumatic cylinder 14 and is fixed by latches 15. The pipe has pins 16 and an arm 17 with an adjustable spring-loaded stop 18 equipped with rollers 19 ( Fig. 5). The bushings 20, the profile protrusion 21 are installed on the neck 22.

 The mechanism for balancing the pipe are suspensions 23 (Fig. 1), pivotally mounted between the pipe and the carriage and consisting of a housing 24 (Fig. 4), a spring block 25 and an air cylinder 26. To fix the docked position of the pipe on the neck there is a flange 27 (Fig. 1 ) The bracket 28 is mounted on the carriage, which is the focus for the pneumatic cylinder of the carriage pre-supply.

 In the initial position (Fig. 1), the carriage 4 with the pipe 9 attached to it is retracted, the protective cover 13 is closed and fixed by the latches 15, the axes of the guide pins 16 are lower than the axes of the bushings 20 by an amount exceeding the misalignment of the connected communications.

 When applying control pressure to the pneumatic cylinder of the clamps 15, they open, the limit switches give a signal that allows the next operation. The control pressure is supplied to the pneumatic cylinder 14 for opening the protective cover 13, the protective cover opens. At a signal from the limit switches, a control pressure is supplied to the pneumatic cylinder of the preliminary supply of the carriage 5, which, acting on the bracket 28, moves the carriage 4 to the position shown in FIG. 2, the limit switches give a signal to the control system, control pressure is supplied to the pneumatic cylinders 26 (Fig. 4) of the suspensions 23 (Fig. 1), the pipe begins to rise under their influence, the rollers 19 (Fig. 5) of the adjustable spring stop 18 interact with the profile the protrusion 21 of the neck 22 and when this happens the preliminary orientation of the pipe relative to the neck.

 At the end of the lift, the axes of the guide pins 16 (Fig. 1) are in the area of the bushings 20, the adjustable spring-loaded stop 18, moving, interacts with the limit switches that give the signal, the control pressure is supplied to the pneumatic cylinder of the docking 6, which moves the carriage with the pipe 9 to the neck 22, the guide pins 16 interact with the bushings 20 and the pipe 9 is finally oriented relative to the neck 22, the limit switches give a signal, the control pressure is applied to the pneumatic cylinder of the clamps 15, which, in interacting with the flange 27 of the neck 22, fix the pipe 9 in the docked position.

 The rods 11 provide plane-parallel movement of the pipe 9 when the neck is oscillating relative to the platform on which the device is installed. Spring compensators 12 rods 11 provide tracking of angular oscillations in the vertical and horizontal planes. The spring block 25 of the suspensions 23 perceives the weight of the pipe in the nominal position.

 The process of undocking and removal of the pipe is carried out in the reverse order.

The execution of the drive in the form of two parallel mounted pneumatic cylinders of the preliminary supply of the carriage and the pneumatic cylinder of the dock, and the orientation device is additionally equipped with a profile protrusion located on the neck and an adjustable spring-loaded stop mounted on the pipe with the possibility of interaction with the said profile protrusion:
- carrying out work in automatic mode;
- improving the reliability of the device;
- reducing the cost of the device.
