DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail cleaning device mounted on a traveling body traveling on a rail such as a traveling crane for cleaning the upper surface of the rail while the traveling body is traveling, and a brush member used for the same. It is.

[0002]

2. Description of the Related Art Cement factories, steel factories, coal storage sites,
At sites where traveling cranes, trolleys, and other traveling objects that run on rails are used in places where dust and mist are generated, such as in scrap factories, dust and mist adhere to and accumulate on the top of the rails. The wheels of the traveling body may slip due to the deposits and deposits.
In particular, when only one of the wheels slips, a meandering force acts on the traveling body, which may cause damage to the rails and wheels.

[0003] Further, when an electric system is wired to the driver's seat such as a traveling crane, the traveling body is grounded to the rail through wheels, or static electricity is grounded from the wheels to the rail. However, if the deposit on the rail is non-conductive such as lime or flour, the driver may be electrocuted due to insufficient grounding due to the deposit.

[0004] Therefore, the rails need to be cleaned at all times. However, when the rails are cleaned using a cleaning tool or a dedicated cleaning device, a dedicated device is sometimes required together with a cleaning staff, and a large-scale factory is required. It is not suitable for application to Therefore, various methods have been proposed in which a cleaning device is mounted on the traveling body and the rail is cleaned when the traveling body travels.

For example, Japanese Utility Model Laid-Open Publication No. Sho 52-130366 discloses a device for arranging a suction hood near wheels of a traveling crane to suction and remove dust. Japanese Utility Model Publication No. Sho 53-38245 discloses a device. There is disclosed a method in which a brush plate is disposed in front of a wheel of a traveling crane to remove deposits on a rail upper surface by traveling of a traveling body.

[0006]

However, the former device sucks dust accumulated on the side surface of the rail, and it is difficult to remove the accumulated material on the upper surface of the rail. There is a problem that the moist deposits are difficult to remove.

As shown in a plan view of FIG. 13 and a cross-sectional view of FIG. 14, a wiper 106 in which a plurality of brushes 105 are arranged at predetermined intervals is a box-shaped frame. The frame 101 is inserted into a traveling body 101 by a bracket 102. This device wipes off deposits and deposits (hereinafter, simply referred to as “deposits”) on the upper surface of the rails with the brush 105. Therefore, depending on the rigidity of the brush, even dry deposits can be wet. Although the brush 105 has a possibility of being removed even if it is deposited, the pressing force for wiping the deposit tends to be insufficient because the brush 105 is in contact with the upper surface of the rail only by the weight of the wiper 106. is there. Therefore, in the case of deposits moistened with oil or water, the wiping power may be insufficient.

Further, since the brush 105 is inserted into the box-shaped frame 101, it is difficult to determine the worn state of the brush from the outside, and the replacement time may be delayed. In particular, since the brush 105 is formed of rubber, when the deposit is hard dust, the wear is severe and it is necessary to frequently replace the dust.

The present invention has been made in view of the problems of the related art,
A rail cleaning device and a sediment that can easily wipe and remove a dry sediment or a wet sediment, and can easily determine the degree of wear of the brush member and easily replace the brush member. It is an object of the present invention to provide various brush members that can be exchanged according to the properties of the brush member.

[0010]

And a brush member attached to the brush plate. The brush member is pressed against the rail upper surface by the weight of the brush plate and the brush member to remove deposits or deposits on the rail upper surface. In the rail cleaning device, a pair of support rods are rotatably mounted on the mounting plate via the connecting member with respect to the mounting plate, and both end portions of the brush plate are provided at the tip side of the support rod. The point of wearing And it has a feature. With such a configuration, not only the own weight of the brush member but also the total gravity of the own weight of the brush plate to which the brush member is attached is used to wipe the deposit on the rail upper surface while pressing the brush member against the upper surface of the rail. Removal can be performed reliably.

As a means for rotatably mounting the brush plate to the mounting plate, a pair of supporting rods are rotatably mounted on both sides of the mounting plate via connecting members, and a tip side of the supporting rod is provided. A simple method is to fix both sides of the brush plate.

The structure of the rotatable connecting member includes a shaft connecting the support rod and the mounting plate,
Preferably, a bearing mounted on the shaft is provided, and the support rod is rotatable with respect to the mounting plate via a bearing. In particular, by providing a stopper that defines the lower limit of rotation of the brush plate in the vicinity of the connecting member, the brush plate is prevented from being damaged by contacting the rail, and the degree of wear of the brush member and the replacement time Can be easily determined.

[0013] Further, by pressing a spring between the mounting plate and the brush plate, it is possible to adjust the pressing force of the brush member to the upper surface of the rail. It is also a preferable embodiment to prevent unnecessary consumption of the brush member due to pressing.

As the material of the brush member, a stainless wire brush or a nylon wire brush formed by bundling a hard wire such as a stainless wire or a nylon wire cut to a predetermined length, or a felt material or a flat belt is laminated. There are felt brushes and belt material brushes formed in a predetermined shape, and it is possible to appropriately use them according to the type and situation of the deposit. As a method of attaching the brush member to the brush plate, in the case of a stainless wire brush or a nylon wire brush, there is a method of implanting a bundle of stainless wires or nylon wires in a number of holes formed in the brush plate. . Further, there is a method in which each brush material is formed into a predetermined shape, and the upper end portion is inserted and fixed in a brush holding frame to form a brush unit, and this is detachably mounted on the brush plate. In this case, It is possible to replace each brush unit, and it is also possible to combine brush units with different types of brush materials according to the state of the deposit.

A brush member is arranged and deposited at an intermediate portion of the brush plate in the front-rear direction along the rail so that a space where the brush member does not exist is formed in a direction obliquely intersecting the rail. It is also a preferable method to make it difficult for objects to accumulate in the brush.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of a rail cleaning device according to the present invention will be described below with reference to the drawings. First, FIG. 1 is a perspective view showing a typical example of a rail cleaning device according to the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a front view thereof, and FIG. 4 is a side view thereof. In these drawings, the rail cleaning device includes a mounting plate 1 in which a mounting hole 6 for mounting the rail cleaning device is formed at a front portion of a wheel of a traveling body (not shown) such as a traveling crane; A pair of brackets 7a, 7b projecting from both sides of the tip of the plate 1, a pair of left and right brush support rods 2a, 2b rotatably attached to each bracket by a connecting member C, and
a, 2b, a brush plate 3 held by bolts 4b and nuts 4a, a brush member B mounted on the lower surface of the brush plate 3, the mounting plate 1 and the support rod 2 (a pair of left and right). When both the support rods 2a and 2b are indicated, they are simply referred to as the support rod 2. The same applies to other cases as well) and a pair of springs 5a and 5b stretched between the support rods 2a and 2b as main constituent members. ing.

As a result, the brush member B is pressed against the upper surface of the rail R by the total weight of the brush plate 3 and the brush support rod 2 in addition to the weight of the brush member B itself, and wipes off the deposits on the upper surface of the rail R. However, if the brush plate 3 and the support rod 2 are formed of an iron plate, the weight of the brush plate 3 and the support rod 2 becomes considerable, and the abrasion of the brush member B may become intense. The pressing force of the brush member B against the rail R can be adjusted by applying an upward pulling force to the plate 3.

Various types of brush members B can be used. FIGS. 1 to 4 show stainless steel and nylon which are effective when dry dust is deposited on rails as in a cement factory or a foundry. An example is shown in the case where a wire brush made of steel is used. This wire brush cuts a high-rigidity wire such as a stainless steel wire or a nylon wire having an appropriate thickness into a predetermined size, bundles a plurality of the wires, and puts them into small holes 8 formed in a large number in the brush plate 3. The brush member B is formed by planting. This planting method is optional, but as shown in FIG. 2, a space S where no brush is planted is formed in the middle of the part plate 3 in a direction intersecting the length direction of the rail R. It is preferable to carry out the implantation of the brush in such a manner.

The space S has a function of discharging dust and the like accumulated between the brushes during the cleaning process of the rail R from the brush portion. For example, the traveling body travels in the direction of arrow A in FIG. When the upper surface of the rail R is cleaned, the cleaning is performed mainly by the brush member B of the front planting portion 3a of the brush plate 3, and the dust accumulated on the upper surface of the rail R is removed by a wire brush. Is wiped off from the upper surface of the rail R and is wiped off to the side of the rail, but a part of the wire enters between the implanted portions of the wire brush, is gradually accumulated, moves backward, and is pushed out to the space S. The dust extruded into the space S is wiped by the brush group of the rear planting portion 3b which is located behind and moves forward, and is blown off to the side of the rail. As a result, clogging of the brush is prevented, and the brush function is maintained for a long time. It is needless to say that even when the traveling body advances in the direction of arrow B in the figure, the space S is located between the front planting portion 3a and the rear planting portion 3b and performs the same operation.

Next, FIG. 5 is a sectional view of a main part showing a structure of a connecting member C for rotatably connecting the support rod 2 to the mounting plate 1, the side of the mounting plate 1 being closer to the bracket 7. The hexagon socket head cap screw 10 is inserted from the end, and the flat rod washer 11a, the spring washer 11b, and the nut 12
And has been concluded. The shaft portion 10 of the bolt 10
“a” is loosely fitted in an opening 7 a formed in the bracket 7, and a sleeve 13 is fitted on the outer periphery thereof. A bearing 14 is fitted inside the bracket 7 of the shaft 10a, and a bearing cover 15 is provided outside the bearing. Thereby, the shaft 10
The support rod 2 fixed to a is rotatable with respect to the bracket 7, that is, the mounting plate 1.

The structure of the rotatable connecting member C is as follows.
The structure is not limited to the one shown in the figure, and another structure may be employed. For example, it is possible to dispose a hollow spacer between the bracket 7 and the support rod 2 and omit the bearing 14. The point is that the support rod 2 only needs to be rotatably connected to the mounting plate 1, and for that purpose, any configuration is optional.

Next, in the process of using the present apparatus, the brush plate 3 gradually tilts forward with the consumption of the brush, and the brush function also gradually decreases. If not specified, the brush plate 3 is
The rail R may be damaged due to direct contact with the rail, or the rail cleaning device itself may be damaged. Therefore, in the present invention, FIG.
As shown in FIGS. 1 to 4, a stopper pin 9 is protruded from the bracket 7 so that the pin 9 contacts the lower surface of the support rod 2 to prevent the support rod 2 from further tilting forward. . The stopper 9 may be incorporated in the connecting member C in addition to the above-mentioned one, and its structure is arbitrary.

Next, FIG. 6 is a side view showing a modification of the embodiment shown in FIGS. 1 to 4, in which a stainless steel wire brush is used. The brush support rod 2 is rotatably connected to the bracket 7 of the mounting plate 1 by a connecting member C, and the brush plate 3 having the stainless steel wire brush B implanted at the tip thereof is held by bolts 4b and nuts 4a. In this embodiment, one end of the grounding lead wire 21 is connected to the mounting plate 1 by bolts and nuts 2.
The difference is that the other end is fixed to the brush plate 3 by bolts and nuts 22a and 22b. That is, in this embodiment, by electrically connecting the traveling body M and the rail R via the grounding lead wire 21, the brush plate 3 and the stainless wire brush B, the non-conductive dust is formed on the upper surface of the rail R. Even if the grounding through the wheels of the traveling body becomes defective due to accumulation of the like, the grounding is performed through this rail cleaning device, so the electric wiring is made in the driver's seat of the traveling crane or the like. In this case, the occupant can be prevented from being electrically shocked due to static electricity charged in a case or in a dry atmosphere.

In the above, an example in which a wire brush typified by a stainless steel brush suitable for dry dust is used has been described. Next, the present invention is suitable for an environment in which dust moistened with water or oil is deposited on the upper surface of the rail. The configuration of the so-called wet brush member will be described. FIG. 7 is a front view showing an embodiment of the brush member B, and FIG. 8 is a side view thereof. In the figure, a brush member B is formed by cutting a felt material having an appropriate thickness into a predetermined size to form a felt brush B, and inserting an upper end thereof into a brush holding frame 30 formed of aluminum or the like and having a U-shaped cross section. The brush unit Bu is formed by fixing with an adhesive or a screw 33 or the like. The brush unit Bu is attached to the brush plate 3 by mounting bolts 31 and nuts 32 having a head portion 31a embedded in the holding frame 30 and a main body portion 31b protruding out of the holding frame. ing.

As the material of the wet brush member, in addition to the felt member, a cotton cloth is laminated and hardened by impregnating with rubber, a transmission flat belt is laminated, and a rubber or other adhesive is used. There are hardened ones.

Next, FIG. 9 is a plan view showing an example in which the brush unit Bu is attached to the brush plate 3. In the brush plate 3, three brush units Bu are provided at predetermined intervals between each brush unit Bu. It is arranged so that the space brush S is formed and obliquely intersects the longitudinal direction of the rail R. As a result, the moist deposits accumulated on the upper surface of the rail R are moved obliquely along the brush surface while being scraped off by the brush units, and fall to the side of the rail R. Note that the other configuration in the figure is the same as that in FIG.

Next, FIG. 10 is a side view showing an embodiment of another brush unit used in the present invention, and FIG.
It is the front view. In this figure, three brush materials B1 to B3 such as felt formed in the above-mentioned predetermined shape are combined into one brush unit Bu, and the central brush material B2 is shown in FIGS. Holding frame 3
The upper end is held at 0. Similar brush materials B1 and B3 are arranged on both sides of the brush material B2, and abutments 40a and 40b are arranged on both upper ends of these three brush materials, and these are integrated by a fastening screw 41 and a nut 42. Things. Then, a bolt 31 and a nut 32 having a head 31a buried in the unit Bu make the unit B
The point that u is configured to be attached to the brush plate 3 is the same as the brush unit in FIGS.

FIG. 12 shows the three-piece brush unit Bu.
FIG. 4 is a plan view of the brush plate showing an example in which the unit is attached to the brush plate 3, and a three-piece unit Bu3 is provided at the center of the brush plate 3.
The brush units Bu1 described above are arranged on both sides of the rail at predetermined intervals one by one so as to obliquely intersect the longitudinal direction of the rail. Thus, the moist deposits accumulated on the upper surface of the rail are moved obliquely along the brush surface while being scraped off and fall to the side of the rail.

The rail cleaning device of the present invention can take various variations within the scope of the idea described in the claims, in addition to those described above with reference to the drawings. Also in the wire brush, a brush unit Bu such as that shown in FIGS. 7 and 8 and FIGS. 10 and 11 can be formed. That is, it is also possible to form a brush unit by binding the ends of the stainless wires and inserting and fixing them in the brush holding frame 30. By using such a brush unit, in the examples shown in FIGS. 1 to 4, when the stainless steel brush is worn out, it is necessary to replace the entire brush plate. However, the brush unit shown in FIGS. 7 and 8 or FIGS. For example, the brush plate 3 can be used as it is and only the brush unit needs to be replaced, so that the cost for replacement can be reduced.

In the example shown in the figure, the brush plate 3 is attached to the distal end portions of the pair of brush support rods 2a and 2b by bolts and nuts. Things are also possible. That is, it is also possible to form a member integrally having the support rods 2 protruding on both sides of the brush plate 3 by welding or cutting.

The combination of the materials of the brush member may be appropriately selected according to the properties of the deposit on the target rail. For example, in the case of the deposit having a little humidity, a stainless wire brush may be used before and after. By disposing the felt brush or a brush formed by laminating the above-mentioned flat brush in the center, it is possible to cope with both the dry type and the wet type.

Further, in arranging the brush member so as to obliquely intersect the longitudinal direction of the rail, in addition to the above-described method in which the brush unit itself is obliquely mounted on the brush plate, the brush plate 3 is parallel to the support rod 2. Instead of attaching the brush unit to the support rod 2, the brush unit can be inclined and intersected with respect to the longitudinal direction of the rail by being arranged obliquely with respect to the support rod 2. Similarly, it is possible to mount the support rod 2 obliquely to the mounting plate 1 or to mount the mounting plate 1 while slightly floating one side of the mounting plate 1 with respect to the traveling body.

[0033]

As described above in detail, according to the present invention, the brush member has a large pressing force of its own weight in consideration of not only the weight of the brush member itself but also the weight of the brush plate 3 and the supporting rod 2 holding the brush member. As a result, the sediment firmly adhered to the rail can be wiped relatively easily. In addition, a spring 5 is stretched between the brush plate 3 and the mounting plate 1 to exert a force for pulling the brush plate 3 upward, thereby optimally adjusting the pressing force of the brush member on the rail upper surface. Is also possible.

In particular, by forming the brush member as the above-described brush unit, various brush materials such as a combination of a stainless wire brush and a felt brush or a flat belt laminate can be used alone or in combination according to the properties of the deposit. Is possible, so that the range of application to rail deposits is widened and, as a result, the effectiveness of the rail cleaning device is further improved.

Further, when the brush member is mounted on the brush plate, the space S where the brush member does not exist is formed in the intermediate portion, so that the brush is less likely to be clogged with the deposit, and a stable cleaning function is provided. It is possible to demonstrate.

Further, the unitization of the brush member facilitates replacement of the worn and worn brush member, and is expected to reduce maintenance costs.

Furthermore, when a stainless wire brush is used, by connecting the mounting plate 1 and the brush plate 3 with the grounding lead wire 5, the contact between the wheels of the traveling body and the rails is poor. Even if it is difficult to expect the grounding action of the wheels, a grounding line via the grounding lead wire and the stainless wire brush can be secured, so that electric shock of the driver due to static electricity is prevented and the safety of the running body is improved. Will also be expected.
