Abstract

FIELD: construction.

SUBSTANCE: safety device of sluice gates is designed for protection of sluice gates against impact of vessels. The safety device comprises a flexible barrier with shock absorbers, two beams that rotate in the horizontal plane and a truss with drives. Two rotary beams are hingedly fixed on opposite sides of the sluice. The rotary truss is installed on one of the rotary beams. The flexible barrier comprises two ropes. Some ends of ropes are connected to shock absorbers. On free ends of ropes there are elements of a coupling unit. Each rope is equipped with stops. Stops, interacting with ends of rotary beams, provide during assembly the necessary tension of ropes. During installation of a barrier device, rotary beams and truss turn by drives perpendicularly to the sluice in one line. Free ends of two ropes are coupled with a coupling unit. The rotary truss turns with a drive relative to the rotary beam to the side opposite to the impact of the vessel, leaving the rope freely sagging only between rotary beams. Reduced capacity of drives and mass of metal structures is achieved by installation of beams and truss, which are rotary in the horizontal plane.

EFFECT: reduced force of rope tension is achieved by reduction of length of a rope freely sagging between rotary beams.

Description

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

Known safety device gate gate in the form of ropes with hydraulic shock absorbers, lowered to the bottom of the channel (AS No. 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.

Known safety device gate gate Lemen (Germany) (see. Fig. 2.9, p. 26 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), 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 ma

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:

- the inevitable increase in the mass of the truss and the power of the drive lifting the truss with increasing channel width;

- the presence of additional mechanisms for tensioning and loosening the steel rope before the hitch-uncoupling, as well as significant pre-tensioning forces of the rope on wide channels in order to reduce its deflection from its own weight.

The technical result of this invention is to reduce the power of the drives and the weight of the metal when installing the safety device, the exclusion of additional mechanisms for regulating the tension of the rope, reducing the tension and deflection of the ropes of the safety device in position in front of the bulk of the vessel.

This is achieved by the fact that the safety device of the gateway gate contains a flexible barrier made, for example, in the form of two ropes, one ends of which are connected to shock absorbers through rollers and rods, and elements of the coupling unit, made, for example, in the form of an eye and are fixed at the free ends a hook, and a rotary truss with a drive mounted on the end of one of two rotary in the horizontal plane of the beams pivotally mounted on opposite sides of the airlock.

The end of the rope with an eye is fixed on the rotary truss with the possibility of unfastening by means of a spring-loaded grip with a drive, for example, an electromagnet.

At the end of the second rotary beam, the end of the rope is fixed with a hook made with the possibility of connection-disconnection with the eye due to a spring-loaded stopper with a drive, for example an electromagnet.

The pivot truss and the second pivot beam are installed so that when they are turned perpendicular to the airlock in a position in front of the bulk of the vessel, the eyelet engages with a hook, thereby connecting the two ropes into a single flexible fence.

Each rope is equipped with stops that interact with the ends of the rotary beams and provide, when mounting the safety device, the necessary rope tension to ensure the smallest deflection of its own weight.

The reduction in drive power and the mass of metal structures when installing a safety device is achieved by installing beams on the opposite sides of the airlock that are rotatable in the horizontal plane.

The exclusion of additional mechanisms for regulating the tension of the ropes in the position of the safety device in front of the bulk of the vessel is achieved by setting the stops interacting with the rotary beams, and the reduction of the tension of the ropes by reducing the span of the freely sagging rope in the position of the rotary beams deployed perpendicular to the lock in the position in front of the bulk of the vessel.

The safety device of the gate 1 of the gateway 2 contains a flexible barrier made in the form of two ropes 3 and 4, one ends connected to the shock absorbers 5 by means of rollers 21, 22 and rods 23, and the free ends connected by a coupling unit, made, for example, in the form of an eye 6, a hook 7, a spring-loaded stopper 8 with an electromagnet 9, while the free end of the rope 3 is connected to the eye 6, and the free end of the rope 4 is connected to the hook 7.

On opposite sides of the airlock 2, beams 10, 11 rotary in the horizontal plane with drives from electromechanisms 12 are mounted pivotally, moreover, the electromechanisms 12 are non-self-braking to ensure the rotation of the rotary beams 10, 11 when the vessel is in the bulk 19. At the end of the rotary beam 10, a truss 13 with a drive is pivotally mounted from the electric cylinder 14. At the end of the rotary beam 11, a hole with flats 24 and a groove 25 is made, in which a hook 7 is mounted connected to the free end of the rope 4, and the groove 25 is made wider than the diameter of Nata 4, but smaller than the flats of the cylindrical part of the hook 7, which ensures the installation of the rope 4 in the swing beam 11. At the end of the swing farm 13 in the lodgement catch 15, the free end of the rope 3 with the eye 6 is fixed by means of a spring-loaded catch 16 kinematically connected with an electromagnet 17. The rope 3 has a hinge 26, allowing it to be rotated together with the rotary truss 13. The rope 3 is equipped with a stop 18, and a stop 27 is made on the hook 7 connected to the rope 4. The stops 18 and 27 of the ropes 3 and 4 are drawn to the ends of the rotary beams 10 and 11, providing n the necessary tension and deflection of ropes 3 and 4, which eliminates the additional mechanisms of tension of ropes 3 and 4.

In this case, the flexible fence made of ropes 3 and 4 along the width of the lock is divided into three parts: from the rollers 21 to the stops 18 and 27 (two parts) and from the stop 18 to the eye 6 (third part), i.e. the length of each part of the sagging rope is 3 times less than the width of the airlock, which reduces the tension of the ropes to achieve acceptable deflection.

The device operates as follows.

During the passage of the vessel 19, the rotary beams 10 and 11 (dashed image) are deployed by actuators with electric mechanisms 12 along the airlock 2, and the rotary truss 13 is driven by an electric cylinder 14 relative to the rotary beam 10 at an angle, for example, 30 ° ... 135 °, which ensures its placement on gateway wall 2.

The end of the rope 4 with the hook 7 is held by the hole 24 on the swing beam 11. The end of the rope 3 is held on the swing farm 13 in the lodgement-catcher 15 with a spring-loaded catch 16.

Before the vessel 19 enters the airlock 2, the rotary beams 10 and 11 are deployed by actuators with electric mechanisms 12 perpendicular to the airlock 2, the rotary truss 13 is deployed by the drive with the electric cylinder 14 in line with the rotary beams 10 and 11.

The eye 6 and the hook 7 are interlocked and fixed by a spring-loaded stopper 8, after which the end of the rope 3 is unfastened with the rotary truss 13 by recessing the spring-loaded gripper 16 by the electromagnet 17. The rotary truss 13 is driven with an electric cylinder and is deployed relative to the rotary beam 10 in the direction opposite to the bulk of the vessel 19 on rope 3 at an angle, for example, 30 ° ... 135 °.

The safety device of the gateway gate is ready to receive the vessel 19.

If the vessel 19 did not brake at the entrance to the lock 2, then it falls onto a rope 3 connected by an eye 6 and a hook 7 to a rope 4. Under the influence of the vessel 19, the rope 3 is bent at the place of the vessel’s bulk, and together with the rope 4 it begins to unfold the swing beams 10 and 11 and stretched by moving through the rollers 21 and 22 of the rod 23 of the shock absorbers 5, and the kinetic energy of the vessel 19 is extinguished due to, for example, fluid flow in the shock absorbers 5 through a throttle (not shown).

After stopping the vessel 19 and returning it to the position in front of the safety device, the rotary beams 10 and 11 with actuators with electromechanisms 12 return to the position perpendicular to the lock 2, ropes 3 and 4 are pulled back by the rods 23 of the shock absorbers 5, for example, by pumping liquid from the rod cavity into the piston (not shown), after which the rotary truss 13 is deployed by the drive with the electric cylinder 14 across the airlock 2, capturing the end of the rope 3 with the eye with a lodgement-catcher 15. A spring-loaded catch 16 fixes the eyes Well, 6 in the cradle-catcher 15. The electromagnet 9 rotates the spring-loaded stopper 8, releasing the eyelet 6 in the grip 7. The pivot truss 13 together with the pivot beams 10 and 11 with electric actuators 12 and the electric cylinder 14 are deployed to the position for the vessel 19 to pass through the gateway 2.
