Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shoe structure such as a sluice gate installed in a water channel such as a corner drop or a current plate installed in an intake such as a power plant.

[Prior Art] A conventional shoe such as a water gate has a certain clearance in order to make it easy to move up and down.

[Problems to be solved by the invention] In such a conventional shoe, since a certain clearance is provided, a gap may occur between the watertight rubber and the water blocking plate when the door is closed, and in addition to water leakage, It sometimes generated vibration.

In addition, since there is no dedicated opening / closing switch in the corner drop, there is a problem that the ascending / descending speed is not uniform and the work swings back and forth and left and right to collide with the side wall of the door stop, and the work cannot be performed smoothly due to the impact.

The present invention is intended to provide a highly practical shoe structure for a floodgate that prevents these water leaks and vibrations and absorbs the impact during a collision.

[Means for Solving the Problems] In order to achieve the above object, a shoe structure such as a floodgate door according to the present invention has a shoe of a door body, in which the shoe is attached to the outer surface of the rubber body with a certain gap. The leaf springs are in contact with each other, and have the flexibility of the leaf springs and the load resistance and restoration of rubber.

It is preferable that the shoe is fixedly attached to both upper and lower ends of the rubber body, and one end of the leaf spring is movably provided.

Further, the shoe may be swingably provided with a mounting portion at one end as a fulcrum.

[Operation] FIG. 1 shows a case where the present invention is applied to a corner drop gate.

As shown in FIGS. 1 and 2, the shoes 2 are attached to both left and right sides of the door body 1 and above and below the front surface, respectively.

The door body 1 is suspended by the lifting beam 3, and the door groove 4
, The leaf spring 2b of the shoe 2 makes elastic contact with the wall surface 4a, and the reaction force causes the watertight rubber 9 to descend while closing the wall surface 4b, thus closing the watertight rubber 9 and the wall surface 4b. Does not occur and does not cause water leakage.

In addition, since the corner drop generally does not have a dedicated switch, it may shake greatly in the front and rear and left and right when it is inserted, and it may collide with the wall surface.In this case, the rubber body attached to the inner surface of the leaf spring 2b.
Impact can be absorbed by the large load resistance and flexibility of 2a.

FIG. 6 shows a case where the present invention is applied to a straightening vane for preventing drift.

As shown in FIGS. 6 to 7, the shoes 2 are provided on the left, right, upper and lower sides of the front surface of the straightening vane 11. In this case, the wedge type cam 13 enhances the crimping force when the straightening vane descends and the straightening vane by the water flow.
11 vibrations are prevented.

When the straightening vane 11 descends and reaches a fixed position, the spindle 14 abuts the bottom portion 15 and moves up a small distance. Since the pusher 22 integrated with the shoe 2 is pushed by the upward movement of the spindle 14 so that the cam 13 is interrupted, the shoe 2 is laterally displaced as shown in FIG. The body 2a is compressed and the rectifying plate is fixed.

The rubber body 2a and the leaf spring 2b have flexibility and are displaced according to the strength of the pressing force, absorb the dimensional error of the door groove, and prevent vibration due to water flow.

When the flow straightening plate 11 is pulled upward, the pressing of the shoe 2 by the wedge-shaped cam 13 is released, so that the flow becomes free again.

[Embodiment] In FIG. 1, a door body 1 of a corner drop sluice gate is provided with a beam 3 so that a lifting beam 3 can move up and down.
The hook 5 is detachably engaged with the engagement pin 6 on the door body 1 side to move it up and down, and when it descends to a fixed position to close the water channel, the hook 5 is removed. Only the door 1 is fixed on the bottom.

As shown in FIGS. 3 to 5, the shoe 2 is composed of a rubber body 2a having a bulge and a leaf spring 2b attached to the outer surface of the rubber body 2a. The rubber body 2a is attached to the surface of the base plate 2c. And tighten both ends with bolts and nuts 7.8.

Only the upper end of the leaf spring 2b is fixed to the base plate 2c together with the rubber body 2a by the bolt nut 7, but the lower end thereof is allowed to move freely.

The base plate 2c is attached to the door body 1.

When it is applied to the current plate 11 of FIG. 6, the pusher 22 having the inclined portion 22a is integrally attached to the back surface of the shoe 2, and the lower end is fastened with the bolt and nut 16, and the fastened portion is used as a fulcrum. The upper end is configured to be swingable to the left and right.

The lower ends of the leaf springs 2b are fastened together by the bolts and nuts 16 so that the elastic force of the rubber allows the bolts and nuts 16 at the lower ends to swing.

The upper end of the leaf spring 2b is attached to the rubber body 2a by a bolt / nut 17, but the nut is loosely tightened so that the movement of the upper end is given a grace period.

The cam 13 is integrally attached to the spindle 14 by the pin 18.

The upper and lower ends of the spindle 14 are supported by brackets 19.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

When inserting the door body, the flexibility of the leaf spring absorbs the door groove dimension error, and the water-tight rubber is closed while sliding on the wall surface of the door groove, so that water leakage does not occur.

When the door body is moved up and down, the shoe collides with the wall surface of the door groove while swinging, but due to the large load resistance and flexibility of the rubber body mounted on the inner surface of the leaf spring, it can absorb the shock and move up and down. Is done smoothly.

 Vibration due to water flow can be prevented.

The structure is simple, durable, and cost effective.
