Description

The invention relates to hydraulic engineering, in particular to a safety device gateway gate.

Known safety device gateway gateway in the form of ropes with hydraulic shock absorbers, lowered to the bottom of the channel (AS 1266927 from 06/12/1985).

The disadvantages of this design are:

- the need to lower the rope together with shock absorbers into water and protect them from corrosion;

- complication of maintenance of hoisting mechanisms of the rope and shock absorbers in the water;

- environmental problems associated with the placement of the rope and mechanisms operating using grease in water.

The safety device of the gate of the Lemen lock (Germany) is known (see Fig. 2.9, p. 26 of the scientific and technical report on topic No. 49 "Development of safety devices for metal structures of the gate of shipping locks" of St. Petersburg State University of Water Communications, St. Petersburg, 2004 .) containing a flexible rope-shaped fence, a hydraulic shock absorber, a lifting truss-barrier with a hydraulic lift, a detachable assembly consisting of a gripping head, a receiving device and a transmission device located at the end of the truss-barrier but.

The presence of a lifting truss-barrier with a hydraulic drive complicates and complicates the design, and the one-sided arrangement of the hydraulic shock absorber leads to the displacement of the vessel to the shore of the channel when it is braked in bulk.

Known safety device gateway installed on the locks of the Velan channel of the deep waterway St. Lawrence (USA, Canada) (see Fig.2.7, page 23 of the scientific and technical report on the topic No. 49 "Development of safety devices for metal structures of the gates of shipping locks" St. Petersburg State University of Water Communications, St. Petersburg, 2004), including a flexible steel rope fence, shock absorbers, a lifting frame with a lifting mechanism and a detachable unit. Before installing the safety device, the rope is loose. In the working position, the fence is stretched across the channel, the truss is raised.

The disadvantages of this design are:

- significant weight of the farm and the power of the drive lifting and lowering the farm;

- the presence of additional mechanisms of fixation - the release of the farm in horizontal and vertical position;

- the presence of additional mechanisms for tensioning and loosening the steel rope in front of the hitch-uncoupling parts of the flexible fence.

The technical result of this invention is the exclusion from the safety device of movable metal structures with power drives that were previously used to install a flexible fence and, therefore, the simplification and cheapening of the safety device, its operation and maintenance.

This is achieved by the fact that the safety device of the gateway gate contains a flexible barrier made in the form of two ropes, one ends of which are connected to shock absorbers and tensioners located on opposite sides of the gateway through guide and deflecting rollers, and coupling nodes made on the other ends are made, for example , in the form of a hook and eyelets with an axle.

The coupling unit of the first part of the rope is connected by a flexible rod, for example, a cable, to one wing of the gateway gate. The cable through the rollers is connected to the winch drive, mounted on the gate leaf gate, or brought to the gate wall. A guide pin is made on the hitch assembly, and a cone catcher is made on the gate leaf of the airlock through which a cable passes connected to the winch.

The coupling unit of the second part of the rope is made in the form of an eye with axle parts (protrusions) protruding beyond its outer surface, which interact with a gripper mounted on the second gate gate gate with an electromechanism, ensuring their coupling-disengagement.

The use of gate valve gates for installing and removing the safety device for the gateway gate made it possible to exclude movable metal structures with power drives from the safety device.

The safety device of the leaves 1 and 2 of the gateway gate 3 contains a flexible barrier made in the form of two ropes 4 and 5. One ends of the ropes 4 and 5 interact with shock absorbers 6 by means of rods 9 with rollers 8 fixed to them and connected to tensioners, for example, in the form suspended through block 10 goods 11.

In figures 1, 4, 5 and 10, blocks 10 and weights 11 are conditionally deployed 90 ° for clarity.

On the ropes 4 and 5 between the rollers 8 and the blocks 10, sliders 12 are fixed, interacting with the spring-loaded stops 13 with the electromechanisms 14. The sliders 12 are arranged to move along the guides 15.

At the other ends of the ropes 4 and 5, elements of the coupling assembly are fixed.

At the end of the rope 4, an eyelet 16 is fixed, permanently connected to the hook 17 using the axis 18.

The other part of the hook 17 is made in the form of a hook with a spring-loaded latch 19 and a groove 20.

An eyelet 21 with an axis 22 is fixed at the end of the rope 5. The axis 22 passes through the eyelet 21 and rises above its surface from two sides, forming protrusions.

The inner part of the axis 22, located inside the eyelet 21, is fixed - unlocked in the groove 20 by the hook 17. The external parts of the axis 22 protruding above the eyelet 21 are fixed - unlocked in the grooves 33 of the bracket 30 of the second gate leaf of the gateway by a grip 31 with an electromechanism 32.

The hook 17 also has a guide pin 23 connected by a flexible rod in the form of a cable 24 to a winch 25 (a flexible rod drive), mounted, for example, on an arm 26 mounted on the leaf 1 of the gateway gate 3. It is possible to install the winch 25 through an intermediate roller on the bank of the gateway 3 (not shown in Fig.).

On the bracket 26 of the first leaf gate gateway also placed conical catcher 27 and a spring-loaded stopper 28 with an electromechanism 29.

In the bracket 30, a spring-loaded grip 31 with an electromechanism 32 is placed, and also in the bracket 30, grooves 33 are made.

The device operates as follows.

Before the ship 34 enters the lock 3, the leaves 1 and 2 of the gate of the lock 3 are closed, the ropes 4 and 5 are interconnected by latching 19 of the axis 22 of the eyelet 21 of the rope 5 into the groove 20 of the hook 17.

The stock 9 shock absorbers 6 are extended. The sliders 12 are brought in for the spring-loaded stops 13 under the action of suspended loads 11.

The safety device for the gateway gate is ready to receive the ship 34.

If the vessel 34 did not brake at the entrance to the lock 3, then it falls on the ropes 4, 5. Under the action of the vessel 34, the ropes 4 and 5 are pulled, moving shock absorbers 6 through the rollers 7, 8 and rod 9.

The kinetic energy of the vessel 34 is extinguished due to, for example, fluid overflow in the shock absorbers 6 through the throttle (not shown in Fig.).

After stopping the vessel 34 and returning it to the position in front of the safety device, the ropes 4 and 5 are pulled back by the rods 9 of the shock absorbers 6, for example, by pumping liquid from the rod cavity and tank into the piston cavity (not shown in FIG.).

For the passage of the vessel 34 through the lock 3, the water levels are equalized outside and in the chamber of the lock 3. At this time, the electromechanism 14 recesses the spring-loaded stops 13, the winch 25 turns on and pulls the cable 24 with the hook 17, the ropes 4, 5 to the gate leafs. While the sliders 12 are moved along the guides 15 in the direction of the rollers 8.

When approaching the gate gate leaves, the guide pin 23 enters the cone catcher 27 and is fixed by a spring-loaded stopper 28 on the bracket 26 mounted on the gate 1 gate leaf 3, thus connecting the rope 4 with the gate gate 3 gate 1.

Together with the movement of the hook 17, the axis 22 of the eyes 21 and the rope 5 are moved.

At the end of the movement, the parts of the axis 22 protruding above the eye 21 interact with the groove 33 of the bracket 30 and are fixed by a spring-loaded grip 31 in the grooves 33 of the bracket 30 mounted on the gate 2 of the gateway 3, thus connecting the cable 5 to the gate 2 of the gateway 3.

When fixing the hook 17 on the bracket 26 by the stopper 28, the latch 19 is fixed, fixing the axis 22 on the hook 17.

Thus, the cables 4 and 5 are separated from each other and are each connected with its own gate leaf: cable 4 - with the leaf 1, and cable 5 - with the leaf 2.

After leveling the water levels in the lock chamber with the external water level, the leaves of the gates 1 and 2 of the lock 3 begin to open.

Under the action of goods 11, when opening the shutters 1 and 2 of the gate of the airlock 3, the sliders 12 begin to move, providing a constant tension of the ropes 4 and 5 until the shutters 1 and 2 of the gate of the gate 3 are fully open.

To install the safety device, the shutters 1 and 2 of the gate of the gateway 3 are closed. At the end of the closing, the groove 20 of the hook 17 is connected to the axis 22 of the rope 5.

The electromechanism 32 moves the hook 31, freeing the axis 22, after which it abuts against the groove 20 of the hook 17.

The electromechanism 29 moves the spring-loaded stopper 28, releasing the guide pin 23 of the hook 17.

The winch 25 unwinds the cable 24. In this case, under the action of suspended loads 11, the sliders 12 move along the guides 15 towards the blocks 10 behind the spring-loaded stops 13, after which the winch 25 stops.

The safety device for the gateway gate is ready to receive the ship 34.
