Description

  The present invention relates to a rail cleaning device that is mounted on a traveling body that travels on a rail such as a traveling crane and cleans the upper surface of the rail as the traveling body travels.

  For example, when a traveling body that moves on wheels, such as a crane or a guide rail that travels on a rail, a guide rail for transportation, or a floor surface, moves on the rail surface, deposits accumulated on the floor surface (for example, Dust, mist, rain water, cooling water, steam generated by plating tanks, dust, etc.) are interposed between the treads of the wheels, causing the wheels to idle, stop, slip, etc. It can be a cause of slipping and sometimes causing serious accidents.

  Therefore, it is necessary to always clean the rail. However, when the rail is cleaned using a cleaning tool or a dedicated cleaning device, the cleaning device is attached to the traveling body, and the rail is cleaned when the traveling body travels. Various schemes have been proposed.

For example, Japanese Patent No. 3249980 discloses a method in which a brush plate is disposed in the front part of a wheel of a traveling crane and deposits on the rail upper surface are removed by traveling of the traveling body.
Japanese Patent No. 3249980

   In this apparatus, for example, when the traveling body advances in the rail direction and the upper surface of the rail is cleaned, the cleaning is performed mainly by the brush member B of the front planting portion of the brush plate. Dust accumulated on the rail is wiped from the rail upper surface with a wire brush and wiped off to the side of the rail, but part of the dust enters between the planted portions of the wire brush and gradually accumulates and moves backward to move into the space. Extruded. The dust pushed out to the space is wiped off by the brush group of the rear planting portion that is located behind and advances, and is wiped off to the side of the rail. The brush is used to wipe off deposits and deposits on the upper surface of the rail. The brush may be disposed so as to cross obliquely with respect to the longitudinal direction of the rail and may be dropped on the rail side.

  However, since the brush is inserted into the box-shaped frame body and the cleaning device is fixed with respect to the traveling direction, the brush is slid to both sides of the traveling direction of the traveling body, and the traveling direction of the cleaning surface Therefore, it was necessary to take measures for the post-treatment that falls or deposits on the plating tank, manufactured parts, storage items, etc.

  Patent Document 1 describes a structure of a connecting member that rotatably connects a support rod to a mounting plate. That is, a hexagon socket head cap screw is inserted from the bracket side of the mounting plate, and the end of the support rod side is fastened by a flat washer, a spring washer, and a nut. The shaft portion of the bolt is loosely fitted into an opening formed in the bracket, and a sleeve is fitted to the outer peripheral portion thereof. Further, a bearing is fitted inside the bracket of the shaft, and a bearing cover is disposed outside the bracket. Thereby, the support rod fixed to the shaft is rotatable with respect to the bracket, that is, the mounting plate.

   However, the structure of the connecting member that can be rotated requires a special configuration for providing a bearing between the bracket and the support rod or for connecting the support rod to the mounting plate so as to be rotatable. .

    Furthermore, when arranging the brush member so as to obliquely intersect the longitudinal direction of the rail, in addition to the method of attaching the brush unit itself to the brush plate at an angle, it is also possible to install the brush unit at an angle to the support rod. It is described in Document 1.

  However, in order to make the brush unit cross at an angle with respect to the longitudinal direction of the rail or to attach the support rod obliquely to the mounting plate, it must be adjusted using the adjusting means each time. Don't be.

In view of the problems of the related art, the present invention changes the direction of the cleaning body via the rotating shaft by the gravity of the cleaning body and the frictional force of the cleaning surface, and slides the deposits to only one side to clean the cleaning surface. An object of the present invention is to provide a cleaning device that travels above.

The rail cleaning device of the present invention is a rail cleaning device that is attached to a traveling body that travels on a rail and that moves and cleans the upper surface of the rail along with the traveling of the traveling body,
The rail cleaning device includes an attachment member fixed to an attachment fitting provided on the traveling body, a rotation member rotatably connected to the attachment member, and a base member attached to the rotation member. In a rail cleaning device comprising a cleaning member coupled to the pedestal member,
The attachment member includes a plate-like attachment portion and a support portion protruding in a right angle direction from the attachment portion, and the support portion includes a bifurcated block body protruding in a right angle direction from the attachment portion, and the rotating member A pivot hole is provided at the center of the pivot hole, and the pivot hole is formed by a pivot shaft provided through a fitting hole provided in the upper projecting portion and the lower projecting portion of the pivot member. The mounting member and the rotating member are coupled to each other in a rotatable manner, and the cleaning member is rotated obliquely with respect to the rail facility direction by the rotation of the rotating shaft, and is pressed against the rail upper surface. The present invention is characterized by a rail cleaning device configured to remove deposits or deposits on the rail upper surface.

  In the rail cleaning device of the present invention, when the traveling body is shifted toward the rail facility, the rotating body rotates by a predetermined angle, the cleaning body obliquely crosses the rail facility direction by a predetermined angle, and the rail deposit is on one side. It is dragged and discharged.

As a structure of a rotating member that rotates around the rotatable rotating shaft and a connecting member that penetrates the rotating shaft, a shaft hole is formed at the center to connect the rotating member to the rotating member. The previous mounting member and the rotating member are rotatably coupled to the shaft hole by a rotating shaft provided through a fitting hole provided in the upper protruding portion and the lower protruding portion of the rotating member. It is preferable that the support rod is rotatable with respect to the mounting plate via a bearing. In particular, by disposing a stopper for defining the lower limit of rotation of the brush plate in the vicinity of the connecting member, the brush plate contacts the rail and the end of the bifurcated block body of the support body contacts the rotation body. Thus, the rotation angle is set to a predetermined angle.

Below, the structure of the rail cleaning apparatus which concerns on this invention is demonstrated based on drawing.
1 is a perspective view showing a typical example of a rail cleaning device according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a plan view thereof, and FIG. 4 is a side view thereof.
In these drawings, the rail cleaning device has an attachment hole for attaching the rail cleaning device to the front part of a wheel of a traveling body (not shown) such as a traveling crane. A mounting member 1 that is attached to the mounting plate T through a connecting member such as a bolt or a nut, a rotating member 2 that is rotatably connected to the mounting member 1, and a pedestal member at the lower end of the rotating member 12 3 and a cleaning member 4 attached to the pedestal member 3 via connecting members such as bolts and nuts are main constituent members.

The attachment member 1 includes a plate-like attachment portion 11 and a support portion 12 protruding from the attachment portion 11 in a right angle direction. The attachment portion 11 is provided with a connection hole 111 so as to be connected to the attachment plate T by a bolt, a nut or the like.

The support portion 12 is composed of a bifurcated block body projecting in a right angle direction from the attachment portion 11, and a shaft hole 13 is provided at the center in order to be rotatably connected to the rotation member 2 described later. The attachment member 1 and the rotation member 2 are separated by a rotation shaft 25 provided in the shaft hole 13 through a fitting hole 24 provided in an upper protrusion 22 and a lower protrusion 23 of the rotation member 2 described later. It is pivotally connected.

At the tip of the bifurcated block body of the support portion 12, a buffer rubber 14 that contacts the body portion 21 of the rotating member 2 and has a stopper action is stretched.
Bearings 26 and 27 are provided in the rotation shaft 25 penetrating the shaft hole 13, the fitting hole 24 of the upper protrusion 22 and the lower protrusion 23. The fitting hole 24 is covered with a blind cover 28 at the opening.
The rotation shaft 25 and the support portion 12 can be rotated integrally with the rotation shaft 25 and the support portion 12 from the side surface of the support portion 12 by a shaft stop pin 29.

The rotating member 2 is attached in the horizontal direction from the cylindrical body part 21, the upper projecting part 22 projecting from the upper part of the cylindrical body part 21 toward the attachment member 1 in the horizontal direction, and the lower part of the cylindrical body part 21. The cylindrical body portion 21 is provided with a through-hole 211 therein, and a lower protrusion portion 23 that protrudes toward the member 1. A groove 213 for guiding a guide pin 212 described later is provided on the inner wall of the through hole 211.

A cylindrical holding member 214 is inserted into the through hole 211. Guide pins 212 are penetrated in the vicinity of the upper end of the holding member 214, and both ends of the guide pins 212 are fitted into guide grooves 213 provided on the inner wall of the rotating member 2. A ball bushing 215 is mounted on the inner surface of the lower cylinder of the rotating member 2 between the cylindrical holding member 214 and a ball bearing 216 is fitted.

A spring suspension pin 218 is protruded. A spring 219 is stretched between the upper spring suspension pin 217 and the lower spring suspension pin 218. The spring 219 exerts an effect of reducing the frictional force between the rail surface such as a rail and the cleaning body by the contraction force. Further, the tension of the brush member 4 to the rail upper surface can be adjusted by stretching the spring 219, and unnecessary wear of the brush member due to excessive pressing of the brush member 4 to the rail upper surface is prevented. It is also a preferred embodiment to do so. According to the present invention, the brush member 4 is pressed against the rail not only by the weight of the brush member itself but also by the large self-weight pressing force including the weight of the rotating member 2 holding the brush member, so that the brush member 4 firmly adheres to the rail. The deposited deposit can be wiped off relatively easily.

As the material of the brush member, a stainless wire brush or nylon wire brush formed by bundling hard wires cut to a predetermined length, such as stainless steel wire or nylon wire, or a laminated shape of felt material or flat belt is used. A felt brush or a belt material brush molded in the above can be used, and can be appropriately used depending on the type and situation of the deposit.

  In particular, by using the brush unit as the above-described brush unit, various brush materials can be used singly or in accordance with the properties of the deposit, such as a combination of a stainless wire brush and a felt brush or a flat belt laminate. Since different types of combinations are possible, the range of application to rail deposits is expanded, and as a result, the effectiveness of the rail cleaning device is further improved.

  Furthermore, when using a stainless steel wire brush, the contact between the mounting base T and the brush member 3 is connected with a grounding lead wire, so that the contact state between the wheel of the traveling body and the rail is poor, and the grounding by the wheel Even if it is difficult to expect the action, the ground line via the ground lead wire and the stainless wire brush can be secured, so that the driver's electric shock due to static electricity is prevented and the safety of the traveling body is expected to be improved. become.
