Abstract

<P>PROBLEM TO BE SOLVED: To provide a scraping tool capable of securely removing iron powder stuck on the under face of an insulation material between the rails. <P>SOLUTION: The scraping tool has a container body 1 opened at the upper face housing a magnet 4 in an appropriate position, having a wider lateral width than the width of the intermediating direction of the insulation material (a) interposed between the end faces of the rail R. In the front end side upper face in the orthogonal direction to the lateral width of the container body 1, a brush 2 coming in contact with the under face of the insulation material (a) is protruded. Further, a grip 3 is protruded at the base end face of the container body 1 corresponding to the front end side. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a scraper for scraping off iron powder adhering to a train rail, which is used to scrape iron powder adhering to a lower surface of a rail joint portion through an insulating material.

  The train rail is connected to each point section through a joint made of an insulating material, and the train is operated by changing the electrical system between the point sections. Iron powder may be magnetically attached to the insulating material portion, conducting between the point sections, disturbing the electrical system, and leading to a major train accident.

  For this reason, the work of removing iron powder adhering to the insulating material part using a tool such as a mop is appropriately performed, but the lower surface of the rail must be removed using a narrow space in place. Therefore, for example, it has to be wiped off with a piece of cloth or the like, and when wiping off, the iron powder falls off from the hand and adheres again with wind or the like, so that a useful instrument has been desired.

  The present invention is proposed as a response to such a demand.

  The width of the insulating material interposed between the rail end faces is wider than the width of the insulating material, and has a container main body with an upper surface opening in which magnets are arranged at appropriate positions, and the front end of the container main body in the direction perpendicular to the horizontal width direction. A brush that is brought into contact with the lower surface of the insulating material is provided on the side upper surface, and a handle is provided on the proximal end surface of the container main body corresponding to the distal end side.

  According to the present invention, the iron powder scraped with a brush is immediately adsorbed to a magnet and can be adsorbed without being scattered, so iron powder adhering to the lower surface of the insulating material between the rails can be reliably removed, It is practical.

  The drawings show an embodiment of the scraper for the iron powder attached to the train rail according to the present invention, FIG. 1 is a partially cutaway plan view, FIG. 2 is a partially cutaway front view, and FIG. FIG. 4 is a partially cutaway front view showing a use state.

  In the figure, 1 is a container main body of the scraping tool A according to the present invention, and the container main body 1 has a width wider than the width of the insulating material a interposed between the end faces of the rail R (longitudinal direction of the rail R). The bottom of the container main body 1 is omitted from the front wall portion of the container main body 1 and a brush 2 made of a base material 2a and a flocking material 2b is provided on the base 2a. 1 is mounted and fixed on the bottom plate 1a, and a handle 3 is projected from the base end surface of the main body 1 (the outer surface of the rear wall piece 1b of the main body 1) corresponding to the tip of the brush 2 side. is there.

  4 is a magnet (permanent) that is placed and fixed on the bottom plate 1a of the container main body 1. The magnet 4 is a rectangular flat plate, and is attached to the front and rear ends of the sleeve 5 that is engaged with and combined with the magnet 4. The pieces 5 a and 5 b are fastened to the bottom plate 1 a by bolts 6 and nuts 7 and are accommodated in the container main body 1.

  Therefore, the scraper A is placed back and forth in a direction perpendicular to the rail R by the handle 3 so that the brush 2 is placed in contact with the lower surface of the insulating material a so that the brush 2 is in contact with the lower surface of the insulating material a. Then, the iron powder (generally, the train wheel is caused by friction with the rail R) r, r,... Adhered to the lower surface of the insulating material a by the brush 2 is scraped off and the magnet 4 installed in the container 1 It is adsorbed by and collected without scattering.

  The shape of the container main body 1 may be freely selected, and the means for fixing the magnets accommodated in the container 1 to the container need not be limited to the structure of the embodiment, and the shape, number, The arrangement position may be freely selected.
