Description

[Detailed description of the invention] The present invention relates to a mechanism for removing deposits attached to guide rails, and is configured as an integrated structure with, for example, a wire rope winding type dust remover, and is capable of raising and lowering a rake for dust removal. The present invention relates to a guide rail deposit removal mechanism for removing deposits from a guide rail in a smooth manner at all times.

Conventionally, as shown in FIG. 5, this type of guide rail deposit removal mechanism includes two guide rails 1, 1 provided facing each other, and a guide rail 1, 1 fitted with the guide rails 1, 1. A side plate 4 comprising one guide roller 2 (in some cases, two guide rollers are connected in the length direction of the guide rails) having a diameter that matches the width direction n of the guide rails 1, 1, and a fixing claw 3. ,
It consists of a side plate drive mechanism 5 that raises and lowers the side plate 4 along the guide rails 1, 1 via a guide roller 2, and when the side plate 4 is raised, it is attached to the guide rails 1, 1 by the fixed claws 3. There are known devices configured to remove deposits such as oyster shells. This guide rail deposit removal mechanism is installed in waterways or pumping stations, etc., and by raising and lowering the rake along the guide rail, it removes dust etc. accumulated in waterways etc. by winding wire rope. It is generally constructed as an integrated structure with a removable dust remover, etc. That is, when the dust remover is integrated with the wire rope winding type dust remover, the guide rail deposit removal mechanism is attached to the rake side plate.

Regarding the case of a wire rope winding type dust remover, the rake is operated only when dust has accumulated in the installed waterway or pumping station, etc. and it is necessary to remove the dust, and at other times. To prevent rusting, etc., it is normally stopped above the water surface. Therefore, if this suspension period is prolonged, deposits such as oyster shells will adhere to the guide rails on which the rake fits and slides, and the inner width between the two opposing guide rails will become significantly narrower, causing the next problem. When trying to operate the rake, the rake's own weight alone may make it difficult to operate, or the guide roller may come off the guide rail, making it inoperable.

In such a case, with the conventional configuration described above, the deposits attached to the guide rail are removed by raising the rake equipped with a mechanism for removing deposits on the guide rail, and the rake is raised via the guide roller. This has the effect of making it smoother.

However, in reality, the rake is usually stopped above the water surface, and considering that most deposits are attached to the part of the guide rail that is below the water surface, it is difficult to keep the rake under its own weight. It is difficult to lower the rake by the rake, which has the disadvantage that the rake often has no substantial effect.

In view of the above-mentioned points, the present invention solves the drawbacks of the conventional guide rail deposit removal mechanism, and eliminates the problem of the rake, etc. of the wire rope winding type dust remover, no matter where it is located. It is an object of the present invention to provide a mechanism for removing deposits from a guide rail, which can always smoothly raise and lower a guide rail.

The present invention includes two guide rails provided opposite to each other, and two guide rails fitted to the guide rails.
a side plate having two guide rollers and two pawls, and a side plate drive mechanism that raises and lowers the side plate along the guide rail via the guide roller, and the two guide rollers have a width of the opposing guide rail. The two claws are provided in series in the direction, and the two claws are each provided with the tip of the guide roller positioned above the guide roller, and the two claws are connected by a link, thereby achieving the objective. has been achieved.

Embodiments will be described below based on embodiments shown in the drawings.

This embodiment applies the guide rail deposit removal mechanism of the present invention to a wire rope winding type dust remover, and can be roughly divided into two guide rails.
1 and 12, a side plate 13, and a side plate drive mechanism 14.

The guide rails 11 and 12 are installed facing each other in a waterway or a pumping station, and their upper ends are attached to a machine frame 15. The side plate 13 is the guide rail 11,
Two guide rollers 16, 17 and two claws 18, 19 are provided on the 12 side, and a rake 20 for removing dust is provided on the other side. The two guide rollers 16, 17 and the two claws 18, 19 are connected to the opposing guide rails 11, 1.
It is fitted between the two so that it can rise and fall. Further, the two guide rollers 16 and 17 are provided in series in the width direction of the opposing guide rails 11 and 12, and the two claws 18 and 19 are attached to the toe portions 21 and 22 of the guide rollers 16 and 17, respectively. is located above. Also, these two claws 18 and 19 are connected to the link 23.
, guide rollers 16, 17, claw 1
8, 19 and the link 23 form a roller link mechanism.

The side plate drive mechanism 14 is composed of a wire rope winding mechanism, and includes two wire ropes 24 and 25, a pulley 26 installed on the machine frame 15, a wire rope winding machine 27, and a wire rope winding machine 28. 24 and 25 are suspended between the side plate 13 and the wire rope winder 27 via pulleys 26, respectively.

In addition, 29 is a wire rope tension adjustment machine, 30
is the dust removal storage section.

Next, the operation of the above configuration will be explained.

First, a description will be given of when the side plate 13 (rake 20) is raised (see FIGS. 1 and 3). When the motor 28 is driven and the wire rope winder 27 winds the wire ropes 24 and 25 at the same speed, the link 23 becomes perpendicular to the guide rails 11 and 12 due to the roller link mechanism, and the guide roller 1
6, 17 and the claws 18, ₁₉ becomes the full inner width n between the guide rails 11, 12 (m ₁
≒n), the side plate 13 (rake 20) rises via the guide rails 11 and 12. Note that the drawings show that when the link 23 is perpendicular to the guide rails 11 and 12, the width m ₁ ≒inner width n, but depending on how the links 23 are connected, Link 23 and guide rails 11, 12
Naturally, there may be some differences in the angle formed between the two.

Then, the ascending pawls 18 and 19 scrape off deposits such as oyster shells that have adhered to the inside of the guide rails 11 and 12, and the obstacles on the guide rollers 16 and 17 are removed, and the rake 20 removes dust accumulated in waterways and the like. is scraped up and stored in the dust removal storage section 30.

Next, the lowering of the side plate 13 (rake 20) will be explained (see FIGS. 2 and 4). By winding only the wire rope 24 with the wire rope winder 27, the side plate 13 can be rolled up by approximately 1/4 using the guide roller 17 as a fulcrum using the roller link mechanism.
When rotated, the guide rollers 16, 17 similarly rotate, and the link 23 also rotates the claws 18, 19, so that the guide rollers 16, 17 and the claws 18, 1
The width m ₂ of the guide rails 11 and 12 is the minimum width (m ₂ <n) with respect to the inner width n of the guide rails 11 and 12, and the side plate 13 (rake 20) can be moved without being obstructed by objects such as oyster shells. It descends via the guide rail 12.
Then, it will move on to the next ascending operation.

In the above description, the side plate drive mechanism 14 has been described as a wire rope winding mechanism, but it is clear that other mechanisms such as a hydraulic type may also be used.

Since the guide rail deposit removal mechanism of the present invention has the above-described configuration, it can always operate smoothly without being hindered by the guide rail deposits, no matter where the side plate is stopped. By configuring it as an integral structure with a wire rope winding type dust remover, etc., it has the effect of providing various types of equipment with reliable operation.
