Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail-to-rail powder particle deposition preventing mechanism, which prevents damage to the rail at the intersection of a rail and a passage, such as when the vehicle is traveling. Under the condition that wheel guard rails are provided to facilitate passage, it relates to a mechanism for appropriately preventing powder particles and the like from filling and accumulating between these rails and wheel guard rails. The purpose of the present invention is to accurately prevent the filling and accumulation of powder particles and the like in order to ensure the safe operation of the vehicle traveling on the rail.

[0002]

2. Description of the Related Art At a crossing portion between a vehicle traveling rail and a passage, a wheel guard rail is attached along the main rail for traveling the vehicle, and the crossing traveling wheel of an automobile traveling in the passage is fitted between the main rails. Difficulty in driving is caused, and at the same time, damage to the rail and the crossing vehicle is protected. That is, such a main rail and the wheel guard rail are spaced at a narrow interval to ensure the engagement of the rail traveling wheels, and are deep enough for the rail traveling wheels to be sufficiently fitted to the rail. Sands, metals, ore powder particles, etc. easily enter and accumulate in the gap between the main rail and the wheel guard rail.

[0003] For example, at a railroad crossing portion that intersects with a passage, such as in a factory with a service wire, such as iron powder or the like between the main rail and the wheel guard rail, especially in an iron mill with a lot of sand or iron powder. Grains easily enter and accumulate, and it is difficult to remove them. The wheels traveling on the rails are compacted, and eventually the wheels are lifted from the rails to cause derailment. It is necessary to prevent accumulation on other roads as well, and to eliminate this, special removal work is performed with a water jet.

[0004]

In any case, according to the above-mentioned prior art, a special removing work for the accumulated dust is required, and the removing work is narrow and deep, especially for the main rail and the wheel guard rail. Under the condition that the opening is narrowed by each rail head, it becomes difficult to discharge because it discharges between the widened inside of the rail abdomen, which requires considerable man-hours and has to be frequently removed. There is.

It should be noted that it is conceivable to apply an elastic filler in the gap between the main rail and the wheel guard rail in order to eliminate the troublesomeness of the removing work, but in this case, the head portion of both rails is narrow. Therefore, it is necessary to remove one of the rails and set it, which requires a considerable number of man-hours. Moreover, when the elastic filler is pressed by the peripheral side portion of the traveling wheel on the rail that protrudes downward from the rail head, the gap between the elastic filler and both rails increases, and the upper deposited powder particles are gradually sandwiched deeply. Inevitably, it becomes very difficult to remove the dust that is sandwiched in this way, as a method of removing one of the rails.

[0006]

The present invention has been studied to eliminate the above-mentioned disadvantages in the prior art, and by adopting a special elastic closing member, the main rail and the wheel guard rail as described above. It is possible to easily set the device to be installed in the space between the elastic blocking member and to discharge dust and the like accumulated on the elastic closing member almost properly by using the treading action of the wheel traveling on the rail, and to enter the deep part of the powder particles for a long time. It succeeded in obtaining a mechanism that does not see, and is as follows.

(1) A hollow elastic restoring operation member made of rubber or the like is provided below the rail head between the rails provided in parallel, and the elastic restoring operation member is provided on both sides of the rail head and the rail. Rail inter-powder powder, characterized in that side wall parts to be set between the support seats are provided in opposition and a top wall part having a bendable middle part is integrally connected between upper end parts of the side wall parts. Grain accumulation prevention mechanism.

(2) The rail inter-powder powder according to item (1), characterized in that the rail head and the projections for joining the corners of the rail support seat are integrally formed above and below the side wall. Grain accumulation prevention mechanism.

(3) Inter-rail powder particle deposition according to the above item (1), characterized in that a restoring actuation assisting member such as sponge rubber is provided on the bendable portion formed between the upper end portions of the side wall portions. Prevention mechanism.

[0010]

A hollow elastic restoring actuating member made of rubber or the like is provided below the rail head between the rails provided in parallel, and the elastic restoring actuating member has a rail head and a rail support seat on both sides. Between the upper and lower side wall portions that are set between the upper and lower side wall portions, the upper wall portion can be appropriately bent by connecting the upper end portions of the side wall portions to the integrally formed upper wall portion with the middle portion being a bendable portion. The distance between the side wall portions on both sides, particularly the upper end portion, is made small, and it is accurately set between the support seats of the rails arranged in parallel and the lower rail head portion bulging on the upper end portion, Hold it in the set position.

The top wall portion having the middle portion as a bendable portion not only facilitates setting and mounting between the rails as described above, but is also momentarily caused by the rail engaging peripheral portion of the wheels of the vehicle traveling on this rail. By receiving the pedal pressure on the intermediate portion of the top wall, even the powder particles are not drawn into the recessed portion of the top wall and the vehicle running is not hindered, and the elastic restoring action after the passage of the pedal pressure. Thus, the sand particles, iron powder, and other powder particles adhering to and retained on the top wall are automatically pushed up from between the rails, and the powder particles are appropriately discharged from between the rails. Therefore, a large amount of powder particles are automatically prevented from accumulating between the rails, that is, on the elastic restoring operation member in any case.

By forming protrusions on the upper and lower sides of the side wall which are joined to the rail head and the corners of the rail support seat, the elastic restoring actuating member tightly joins and seals the rail side wall. Appropriately prevent powder particles from entering between the rail and the elastic restoring operation member. Further, by strongly joining the lower corner portion of the rail head portion by the above-mentioned projection, even if the instantaneous pedaling pressure by the wheel acts as described above, the joining relationship effectively held at the joining position can be obtained. Continuing, the dust and the like are prevented from invading the inside beyond the joint projection portion even by the restoration operation after the momentary pedaling, and the proper elimination is performed by the restoration operation.

The projections at the lower portions of the side walls are joined to the rail support seat corners to seal the corners, but the bottom of the elastic restoring actuating member is held in a stable position between the rails, so that the vehicle travels. As described above, the elastic restoring member is displaced by the sudden treading action and the subsequent restoring operation depending on the wheel at the time, and the concave receiving of the powder particles and dust by the top wall portion of the elastic restoring member as described above is received. Or, the subsequent elimination action can be effectively obtained.

By providing a restoring operation assisting member such as sponge rubber on the bendable portion formed by connecting between the upper ends of the side wall portions, the distance between the parallel rails such as the main rail and the wheel guard rail is increased. Even in the case, the top wall portion is appropriately pushed up to form a predetermined rail-to-rail closed state, and therefore, accumulation of powder particles and the like accumulated on the top wall portion of the elastic restoring operation member is limited,
This makes it possible to more effectively perform the elimination action after the passage of the pedaling pressure by the wheels.

As shown in FIG. 2, the head 12 swells and the bottom support seats 13 are projected on both sides for stable mounting.

In the present invention, a hollow elastic restoring member 3 made of rubber or the like is provided between the rails 1 and 2 set as described above, and the elastic restoring member 3 is shown in FIG. Shows the cross-sectional shape in the natural state,
The rail head 12 and the rail support seat 1 at the bottom described above on both sides.
The side wall portions 30 and 30 to be set between the side wall portion 3 and the side wall portion 30 are oppositely arranged, and the top wall portion 31 is integrally formed on the top surface. Is formed with a joint end 32 adapted to be joined to the lower jaw of the rail head 12, and the lower end of the side wall portion 30 is defined as another joint end 33 for the corner portion on the support seat 13. There is.

The top wall portion 31 of the elastic restoring operation member 3 has a structure in which the central portion is slightly bent downward even in a natural state as shown in FIG. 2 separately. When the rails 1 and 2 are set between the rails 1 and 2, the bending is increased, and the entire top wall portion 31 forms a bendable portion mainly having a central portion. Further, in the illustrated one, as a more preferable configuration, a concave streak portion 34 is formed in the central portion of the top wall portion 31 so that the above-described bending action can be obtained more remarkably.

FIG. 3 and subsequent figures show another structural example of the elastic restoring operation member 3 in the present invention. That is, the above-mentioned ones in FIGS. 1 and 2 are formed by bending the ones having substantially the same thickness in cross section, but the one in FIG. 3 is not a box shape in which the through holes 8 are arranged side by side in cross section. , A plate-like restoration operation assisting portion 5 is integrally formed in the middle thereof, and joint projections 6 and 6 for the corner portions of the rail head 12 are provided on both sides of the upper portion, and corners of the rail support seat 13 are provided on both sides of the lower portion The ear-shaped joining projections 7, 7 are provided opposite to each other.

That is, the elastic restoring actuating member 3 shown in FIG. 3 can obtain a joining action and an elastic restoring action in which the whole of the member 3 is integrally connected, and, for example, the top wall portion 31 thereof runs. When a rolling action is applied by the vehicle wheel, the joining action force at each joining projection 6, 6, and 7, 7 is improved to prevent dust and particles from entering between the rail and the wheel passage. The restoring operation force afterward is increased to make the dust discharging effect effective.

In principle, the structure shown in FIG. 4 is different from that shown in FIGS.
Although it has a cross-sectional structure similar to that shown in FIG. 2, its top wall portion 31 has a shape bent upward as opposed to that of FIGS. When it is set between the rails 1 and 2, the top wall portion 31 projects further upward as shown by the phantom line in FIG. 4, and the accumulation of dust on the top wall portion 31 is reduced.

Further, what is set in the phantom line state in FIG. 4 largely dents when the traveling wheels on the rail 1 are pressed, and the subsequent restoring operation more efficiently pushes up or removes dust. can do.

The elastic restoring operation member 3 shown in FIG. 5 has substantially the same shape as that of FIGS. 1 and 2, but a porous restoring operation assisting portion 4 such as sponge rubber is used as the restoring operation assisting portion. The auxiliary member 4 can be set in an appropriate compressed state, and is stable in the overall operation member 3 even when the distance between the rails 1 and 2 is large as described above. It is possible to obtain a completely blocked state or a restoring action.

Further, FIG. 6 shows a box-like joining projection similar to that of FIG. 3 described above, but the joining projections 35 are arcuate on both sides at the bottom, similar to the upper joining projections 6, 6. With this structure, the supporting seats 13 and 13 of the rails 1 and 2 can be stably set, and the passing of the traveling wheels can provide a preferable dust accommodating and discharging effect after passing.
