Description

The invention relates to hydraulic engineering and can be used in the equipment of locks and channels.

The purpose of the invention is to behave reliably by reducing the speed of movement of the sash at the end of the opening and reducing the loads on the wheels of the trolley.

The drawing shows a diagram of the device for non-displacing the leaf of the gate, top view.

The shutter 1 of the structure (its angle of rotation, tff, is 70 °), the hinge 2, with an eye on the lug, is connected with a pull 3, the second end of which is also a hinge rom 4 fixed on the trolley 5, moving along rigid guides 6 The hinge 4 on the trolley 5 is connected to the eye of the rod 7 of the hydraulic cylinder 8 mounted on the hinge support 9 with the hinge 10 placed on the platform 11 of the structure. The diagram shows the hinged fastening of a hydraulic cylinder with a blind cover; a trolley (not shown) should be installed under the flow collar to eliminate the weight of the hydraulic cylinder 8 seals from its own weight in order to avoid wear and damage to the rod 7 or pass krishki. It is also possible to pivotally fasten the hydraulic cylinder 8 anywhere on its body. Guides, 6 are located horizontally at an acute angle to the axis of the structure, for example a gateway or channel: a5 and axis 10

The cylinder is located at an acute angle a, to the axis of the guides 6.

The device works as follows.

In the initial position, the flap 1 is open, the mechanism is in the position shown by the dotted line in the drawing. At the signal for opening, the pressurized oil enters the rodless cavity of the hydraulic cylinder 8j, the piston and the rod 7 begin to move out, moving the carriage 5 and closing valve 1 through pull 3, ensures that the initial speed of the trolley 1: and J and : cusps 1 are purely kinematic nyTeMj due to the small initial gear ratio. At the same time, the initial velocity of the shutter I is small and provides both small water resistance forces and, therefore, reduction of the working pressure in the pressure cavity of the hydro1 | cylinder 8 and the reaction in support 9,

As the extension of the rod 7 and. the movement of the trolley., 5 in the guides of the angle of 6, decreases, its influence - ime on the gear ratio decreases and in the middle part of the way the law of the sash approximates to the law of motion of the known device. Then, the gear ratio is again reduced due to the fact that when the closed position of the sash 1 is the angle of the direction of movement of the carriage 5 and the thrust 3 is approximately 95
