SU41453A1 - Sluice gates - Google Patents

Description

The invention relates to: sluice rotates rotating on a horizontal axis, and consists in that the supporting devices are fixed at both ends of the door leaf, and on the bottom of the cabinet part of the gateway there are corresponding supports (sockets) so that when the position is lowered, the door panel of Chokoitsk these supports all supporting devices located at both ends of the cloth. This feature aims to use the gate to maintain water pressure on both sides at different times.

In the described gates special support devices are used.

In FIG. 1 shows a side view of the proposed gate in the lowered position (the dotted line shows the gate in the raised position on the supports of one and the other end); FIG. 2 is a side view of the support device when the gate positions are raised; FIG. 3 is a view of the support device from the side of the gateway chamber, with a cut-out along I-I in FIG. 2; FIG. 4 is a side view of the support device in the lowered position of the gate; FIG. 5 - support subclass - view from the side of the lock chamber.

Supporting devices E (Fig. 1) are fixed at both ends of the door leaf.

On the bottom of the cabinet part of the gate, there are supports (stoppers) F corresponding to the supporting devices E. In the lowered position, the door panel rests on the underside of all the supporting parts.

In the presence of water backwater Cviesa (according to the drawing), the gate rises to the right (shown in dotted) position using cables C attached to the panel at points A. If there is backwater to the right, the gate rises to the left position using cables D attached to the panel at points B .

The gate is maneuvered by a lift mechanism L and block N.

The gate support device is as follows. The panel 5 (Fig. 2-5) is rigidly attached (bolted) a part /, to which, with the help of a hinge g, is attached a part c, which has a supporting roller d in the lower part, which fits into the corresponding slot of the subgroup b mounted on the casting a . At the top, the part c has oblique planes h and i, designed to abut against part /.

In liner b to guide roller-p. d nest in the nest

walls p, between which there are protrusions of a subgun with beveled edges. Hooks q can be mounted on the walls p to prevent the support devices from jumping out of their seats by hooking the protrusions t onto the parts c. Holes are provided in the walls p for squeezing sand, silt, etc., through them.

The hinged attachment of the part with is intended to obtain a support of such a design that would allow free movement of the lower part of the panel with its raised positions. In this movement of the lower part of the panel, it is intended to obtain a uniform clamp to the stop parts of the sealing bars t located along the contour of the panel, and free the supporting parts from the horizontal forces during the raised position of the gate.

When lifting the panel, for example, to the left position, the part with is supported by the end part L on the casting /. After the gate is raised, a pressure is created which presses the panel against the walls of the cabinet part, with the end plane h of part c moving away from the casting /. When the panel is lowered from the left position, under the weight of the thief, the part rotates with respect to the axis of the roller d, in the direction of the reverse of the clock, the arrow, resulting in a casting / end of the edge / part c. Upon further lowering of the gate, after their known position, the weight of the gate will force the part to rotate relative to the roller d in the opposite direction} (clockwise).

Since the rotation of the part with at the beginning of the action of the head and with the lowering of the panel will occur abruptly, there will be a loss of force, which is also reflected on the supports. To prevent such a shock, the Dampers k are arranged on the support, representing cylinders in which the movement of the pistons.

Cylinders have holes for water and water.

When the gate moves from the reference position to another, the first part of one of the shock absorbers enters the cylinder, while the piston of the other leaves the cylinder. During the reverse rotation of the gate, the shock absorbers work in the reverse order.

Claims (4)

1. Sluice gates rotating on a horizontal axis, characterized in that, in order to use the gate to maintain water pressure on both sides at different times, supporting devices E are fixed on both ends of the gate panel, and corresponding supports are mounted on the bottom of the tongue section. (pods) F so that when the position is lowered, the panel rests on these supports with all supporting parts. 2. Gate 1U and. 1, characterized in that in order to press the water against the sealing frame correctly, each supporting device E consists of a part I / rigidly attached to the door, and a hinged supporting part plane Li at the top, and at the bottom of the support roller d, included in the socket support (subframe) F, provided with guide walls p with skewed protrusions and. 3. A gate according to claim 2, characterized in that hooks q are mounted on the support (subframe) F and protrusions on the supporting portions of the cloth to prevent undesired popping of the support devices from their seats. 4.In the gate on the PP. 2 and 3 use hydraulic shock absorbers A, which connect the parts / and from the supporting building, in order to protect the gate from sudden surges when raising or lowering them.
