Description

one

The invention relates to driving trains from river vessels using the push method on rivers that have narrow and winding sections for navigation, in particular, to pusher tugs and pushed vessels.

Known devices for pushed river vessels are known, including: power drillo located in the diametral plane, the rod of which is coupled with the pushed vessel, and two on-board automatic de-locks with independent control connected to the mounted beams on the pushed vessel having a circular cross section.

However, such devices are structurally complex and they do not allow for the removal of the depot locks when the ships deviate to the required angle of bending.

The purpose of the invention is to simplify the device by using tick-type locks.

For this, the depot beams are installed vertically, and the depot lock is made with a semicircular notch under the depot head, which is coupled by means of a locking hook to the locking cam, and a locking claw securing the depot head in the notch of the lock.

In order to ensure the remote dismounting of the dead locks in the process of bending the composition, it is advisable to carry out each dead lock with a hydraulic cylinder, the stem of which can be equipped with a toothed rack interacting with a gear mounted on the axis of the locking cam.

FIG. 1 shows a scene device for pushed river vessels; in fig. 2- coupling lock, side and top view; in fig. 3 shows a section A-A in FIG. 2 with the lock closed; in fig. 4 is the same, with the lock open.

The hitch for pushed river vessels 1 and 2 consists of a power cylinder 3 located in the diametrical plane of the vessel 1, the rod 4 of which is coupled with the pushed vessel 2, and two onboard automatic depot locks 5 with independent control. The hinge locks 5 are connected to the coupling beams 6 on the vessel 2, having round-section heads 7, which are fixed in the semicircular grooves 8 of the coupling locks by means of locking claws 9.

Each locking claw is fixed on the axis 10 and through the locking hook 11, which is loosely mounted on the axis 12, is connected to the locking cam 13. On the axis 10 of the locking claws 9, a spring-loaded shank 14 is also assembled, which is spring 15.

Each coupling lock 5 is equipped with a hydraulic cylinder 16, the rod 17 of which is equipped with a toothed rack 18 that interacts with the bristles 19, which, together with the two-strand pulley 20, is seated on the axis 21 of the locking cam 13. The pulley 20 is connected by means of a cable through the roller 22 to the spring 23, which returns the locking cam 13 to its original position. A cable 24 is fastened in the lower stream of the pulley 20 and is connected with a manual winch of the reserve uncoupling of the locking locks 5.

The hitch works as follows.

When the pushed train moves in motion without bending, both coupling locks 5 are coupled with coupling beams 6 and work as in a regular (rigid) train. Power cylinder 3 is not operational.

If it is necessary to bend the pushed composition, the working fluid is simultaneously fed into the hydraulic power cylinder 3 and into the hydraulic cylinder 16 of one of the locks, depending on which direction the bending should be performed. As a result, one lock is released, and the pin 4 of the power cylinder 5 begins to deflect the vessel relative to the non-disengaged lock.

When the flow of working fluid in the cylinder 16 of the lock occurs the following.

The rod 17 of the hydraulic cylinder 16 extends and its rack and pinion 18 rotates the gear 19, and with it the locking cam 13 (direction of rotation in the direction of the arrow in FIG. 3), which will take the position shown in FIG. 4. Rotating the cam allows the locking hook to be turned. This will turn the locking claw 9, and the head 7 of the drawbar 6 will come out of the recess. " All the details of the lock will take the position shown in FIG. four.

To straighten out the composition of the pushed vessels, the working fluid is fed into the schtokovaya cavity of the power cylinder 3, and the vessels begin to collapse. The coupling beam 6 approaches the lock 5, presses the shank 14, as a result of which the locking tong 9 rotates, closes the head 7 of the coupling beam and frees up space to rotate the locking hook 11. The locking cam 13 rotates by the spring 23 and turns the locking hook 11 to the position shown in fig. 3

As a result of rotation of the locking cam 13 gear 19, I act on the rack 18, returns the piston of the hydraulic 10 of the cylinder 16 to its original position.

Hydraulic control is not described, as it is not an object of the invention. It is carried out with the use of a nomery type start-regulating apparatus. The control panel in the wheelhouse of the vessel must simultaneously provide the supply of working fluid to the power cylinder 5 and to the hydraulic cylinder 16 of one of the locks during bending and only to the power cylinder 3 when extracting the train.
