Description

[Technical Field]

[0001] This invention relates to a rail tread wiper for wiping away dirt such as oil and dust from rail treads. [Background technology]

[0002] After replacing crushed stone trackbed or performing other track maintenance work on or off the track, if dirt is found on the rail treads, it is necessary to wipe it off before leaving the site. This is because oil on the rail treads can cause wheels to spin when trains pass, while dust or footprints can lead train drivers to mistake the dirt for a rail problem. For this reason, if dirt is found on the rail treads after track maintenance work, workers have traditionally wiped it off with a mop or other tool. Here, cleaning tools have been proposed that have a mat pressing member with a cleaning sheet attached to the end of a rod-shaped handle (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication number 6-21421 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-299659 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the cleaning tools described in the above-mentioned Patent Documents 1 and 2 are for general household cleaning, not for railway rail maintenance work, and the surface against which the wiping mat is pressed is flat, so they are not suitable for wiping the curved tread surfaces of railway rails.

[0005] Therefore, the present invention has been made in consideration of such problems, and aims to provide a rail tread wiper suitable for wiping off dirt such as oil, footprints, dust, etc. from railway rail treads. [Means for solving the problem]

[0006] In order to solve the above problem, the rail tread wiper of the present invention is characterized by having a rod-shaped handle bar that is grasped by the user, and a mat pressing member that has a connecting part on the upper side that is rotatably connected to the tip of the handle bar, and a mat pressing member that has a tread-shaped curved surface on the lower side that curves according to the shape of the rail tread and presses down on the wiping mat that wipes the rail tread. In addition, in the rail tread wiping device of the present invention, the mat pressing member is provided with a bolt hole into which an anti-slip bolt is screwed, passing from the upper surface side to the tread-shaped curved surface on the lower surface side, and the tip of the shank of the anti-slip bolt screwed into the bolt hole from the upper surface side protrudes from the tread-shaped curved surface on the lower surface side, and the protruding tip of the shank of the anti-slip bolt prevents the wiping mat from slipping against the mat pressing member. In addition, the rail tread wiper of the present invention is also characterized in that the bolt holes are provided at the front and rear of the mat pressing member, and the anti-slip bolts are provided at the front and rear of the mat pressing member. In addition, the rail tread wiper of the present invention is also characterized in that the bolt holes are provided in multiple spaces spaced apart in the left-right direction of the mat pressing member, and the anti-slip bolts are provided in multiple spaces spaced apart in the left-right direction of the mat pressing member. In addition, the rail tread wiper of the present invention is characterized in that the tip of the handle bar and the connection part of the mat pressing member each have a connecting hole into which a connecting pin can be inserted, and the handle bar and the mat pressing member can be separated by inserting and removing the connecting pin. [Effects of the Invention]

[0007] The rail tread wiper of the present invention comprises a handle bar and a mat pressing member having a connecting portion on the upper surface that is rotatably connected to the tip of the handle bar, and a mat pressing member having a tread-shaped curved surface on the lower surface that curves according to the shape of the rail tread and presses down on a wiping mat that wipes the rail tread. Therefore, the worker can easily and efficiently wipe away oil, debris, and other dirt adhering to the rail tread by grasping the handle bar and pressing the wiping mat against the rail tread with the curved tread surface of the mat pressing member.

[0009] The rail tread wiper 1 according to the present invention will be described in detail below with reference to the accompanying drawings. Note that the embodiment described below is merely an example of the present invention, and the present invention is not limited to the rail tread wiper 1 according to the following embodiment, and can be modified as appropriate within the scope of the technical concept of the present invention.

[0010] <Configuration of rail tread wiper 1 of embodiment 1> The rail tread wiper 1 of the embodiment of the present invention is composed of a rod-shaped handle bar 11 that the user grasps, a connecting pin 12, a mat pressing member 13, an anti-slip bolt 14, a wiping mat 15, etc., as shown in Figures 1 to 4, etc.

[0011] (Handle bar 11) The handle bar 11 is a rod-shaped member made of a metal pipe such as aluminum or wood that is grasped by the user, as shown in Figures 4(a) to (c), and has a pin insertion hole 11a at its tip (lower end) into which the connecting pin 12 is inserted.

[0012] (Connecting pin 12) As shown in Figure 5, the connecting pin 12 is a well-known pin with a retaining protrusion 12a that moves in and out using a spring (not shown) built into the tip, and a ring 12b is provided at the rear end for hanging on a key holder (not shown) or the like to prevent loss, etc.

[0013] (Mat pressing member 13) As shown in Figures 1 to 3, the mat pressing member 13 is composed of a connecting part 13a that is rotatably connected to the tip of the handle bar 11 via a connecting pin 12, and a mat pressing part 13b that is fixed to the connecting part 13a with a well-known flat head bolt 13c, nut 13d, washer 13e, etc.

[0014] As shown in Figures 6 to 10, the connecting portion 13a is arranged upright and spaced apart by the width of the handle bar 11, and has a pair of connecting pieces 13a1, 13a1, each having a pin hole 13a11 through which the connecting pin 12 is passed, and a flat connecting base portion 13a2 welded to the lower part of the pair of connecting pieces 13a1, 13a1 and fixed by a mat pressing portion 13b, a flat head bolt 13c, a nut 13d, a washer 13e, etc.

[0015] As shown in Figures 6 to 10, the mat pressing portion 13b is a member that is fixed to the connecting base portion 13a2 of the connecting portion 13a by two sets of flat head bolts 13c, nuts 13d, washers 13e, etc., and has bolt holes through which the two flat head bolts 13c each pass and are screwed together, and the underside is provided with a tread-shaped curved surface 13b1 that is curved according to the shape of the tread of the rail R, and is configured so that the tread-shaped curved surface 13b1 presses down the wiping mat 15 that wipes the tread of the rail R according to the curved shape of the tread of the rail R.

[0016] In addition, in order to press the wiping mat 15 against the tread surface of the rail R from above and wipe the tread surface of the rail R, the mat pressing portion 13b has bolt holes 13b2 at three locations on each side of the front and back in the longitudinal direction, as shown in Figures 6 to 10, into which anti-slip bolts 14 that penetrate from the upper surface side to the lower surface side tread-shaped curved surface 13b1 are screwed, and the tips of the shanks 14b of the anti-slip bolts 14 that are screwed into the bolt holes 13b2 from the upper surface side protrude from the lower surface side tread-shaped curved surface 13b1, and the tips of the shanks 14b of the anti-slip bolts 14 prevent the wiping mat 15 from slipping against the mat pressing member 13.

[0017] (Anti-slip bolt 14) Anti-slip bolt 14 has head 14a and shank 14b with a male thread, and is a well-known anti-slip bolt that screws into the female thread of bolt hole 13b2 of mat pressing member 13. As shown in Fig. 8, length L of shank 14b is greater than the sum of thickness T1 of mat pressing member 13 and thickness T2 of washer 14c, that is, L > T1 + T2. Therefore, as shown in Figs. 7 to 10, when anti-slip bolt 14 is attached by screwing it into bolt hole 13b2 of mat pressing member 13 via washer 14c, the tip of shank 14b of anti-slip bolt 14 protrudes from tread-shaped curved surface 13b1 of mat pressing member 13, as described above, to prevent slipping of wiping mat 15.

[0018] This is because various types of wiping mats 15, such as paper, nonwoven fabric, thick towels, and dustcloths, are used depending on the object to be wiped, such as oil, dust, footprints, and grinding residue, and therefore it is difficult to adopt a method such as clamping and fixing the wiping mat 15. Therefore, in the rail tread wiper 1 of the embodiment according to the present invention, the tip of the shaft 14b of the anti-slip bolt 14 protrudes from the tread-shaped curved surface 13b1 of the mat pressing member 13, and a spike method is adopted to prevent the wiping mat 15 from slipping. Of course, as shown in Figures 9 and 10, the head 13c1 of the flat head bolt 13c inserted from the tread-shaped curved surface 13b1 of the mat pressing member 13 may also protrude from the tread-shaped curved surface 13b1 to prevent the wiping mat 15 from slipping.

[0019] (wiping mat 15) The wiping mat 15 to be used varies depending on the dirt level at the time, such as dust, oil, footprints, and grinding residue adhering to the tread surface of the rail R. For example, a dustcloth or waste cloth is used for dust, and a commercially available oil absorption mat, also known as an oil medimat, is used for oil. In the case of a thin and large wiping mat 15 such as a commercially available oil absorption mat, it is advisable to secure a certain thickness by folding it in thirds or the like, so that it is thicker than the protruding length (L-(T1+T2)) of the shank 14b of the anti-slip bolt 14 protruding from the curved surface 13b1 of the tread shape.

[0020] Since the thickness etc. of the wiping mat 15 varies depending on the material of the mat, the wiping mat 15 is fixed to the mat pressing member 13 using a spike method using the tip of the shaft 14b of the anti-slip bolt 14 attached so as to protrude from the tread-shaped curved surface 13b1 of the mat pressing member 13.

[0021] Therefore, when the rail tread wiper 1 of embodiment 1 configured as described above is used and the wiping mat 15 placed on the tread of the rail R is pressed and pulled with the tread-shaped curved surface 13b1 of the mat pressing member 13 of the rail tread wiper 1 as shown in Figure 1, the tread-shaped curved surface 13b1 of the mat pressing member 13 is curved according to the shape of the tread of the rail R, so the tread-shaped curved surface 13b1 can cause the wiping mat 15 to reliably wipe the tread of the rail R according to its shape without leaving any areas unwiped.

[0022] Furthermore, in the rail tread wiper 1 of embodiment 1, the tip of the shaft 14b of the anti-slip bolt 14 protruding from the tread-shaped curved surface 13b1 hits the wiping mat 15 like a spike, preventing the wiping mat 15 from slipping. This means that cleaning work can be performed reliably and in a short time without worrying about the wiping mat 15 slipping or falling off, and with little consideration given to differences in the material or thickness of the wiping mat 15, thereby improving the work efficiency of the cleaning work.

[0023] <Summary of the rail tread wiper 1 according to the embodiment of the present invention> As described above, the rail tread wiper 1 of embodiment 1 of the present invention has a rod-shaped handle bar 11 that is grasped by the user, and a mat pressing member 15 on the upper side which has a connecting portion 13 that is rotatably connected to the tip of the handle bar 11, and on the lower side which is curved according to the shape of the tread of the rail R and has a tread-shaped curved surface 13b1 that presses down on the wiping mat 15 that wipes the tread of the rail R.

[0024] Therefore, when the wiping mat 15 placed on the tread of the rail R is pressed and pulled by the tread-shaped curved surface 13b1 of the mat pressing member 13 of the rail tread wiper 1, the wiping mat 15 is pressed tightly against the tread of the rail R by the tread-shaped curved surface 13b1 of the mat pressing member 13, which is curved according to the shape of the tread of the rail R. This allows the tread of the rail R to be reliably wiped without leaving any areas unwiped according to its shape.

[0025] In addition, the mat pressing member 13 is provided with a bolt hole 13b2 that penetrates from the upper surface side to the tread-shaped curved surface 13b1 on the lower surface side, and the tip of the shaft portion 14b of the anti-slip bolt 14 that is screwed into the bolt hole 13b2 from the upper surface side protrudes from the tread-shaped curved surface 13b1 on the lower surface side.

[0026] Therefore, the tip of the shaft 14b of the anti-slip bolt 14 acts as an anti-slip device for the wiping mat 15, so even if the mat pressing member 13 is pressed against and pulled on the wiping mat 15 placed on the tread surface of the rail R of the railway, the wiping mat 15 does not slip or fall off from the mat pressing member 13, making it possible to easily wipe away dirt such as oil and dust adhering to the tread surface of the rail R of the railway, and thus the wiping work of the rail R tread surface can be carried out efficiently.

[0027] In particular, in the rail tread wiper 1 of embodiment 1, the tip of the shaft 14b of the anti-slip bolt 14 protruding from the tread-shaped curved surface 13b1 of the mat pressing member 13 prevents the wiping mat 15 from slipping, so cleaning work can be performed reliably and in a short time without worrying about differences in the material or thickness of the wiping mat 15 or the wiping mat 15 slipping or falling off, which also improves the work efficiency of the cleaning work.

[0028] In addition, in the rail tread wiper 1 according to the embodiment of the present invention, the bolt holes 13b2 are provided at the front and rear of the mat pressing portion 13b, and the anti-slip bolts 14 are provided at the front and rear of the mat pressing portion 13b.

[0029] Therefore, the wiping mat 15 can be reliably prevented from shifting by the tips of the shafts 14b of the anti-slip bolts 14 that protrude from the front and rear of the tread-shaped curved surface 13b1 of the mat pressing portion 13b, so cleaning work can be carried out reliably and in a short time without worrying about differences in the material or thickness of the wiping mat 15 or the wiping mat 15 shifting or falling off, which also improves the work efficiency of the cleaning work.

[0030] In addition, in the rail tread wiper 1 of the embodiment of the present invention, the bolt holes 13b2 are provided at three locations spaced apart in the left-right direction of the mat pressing portion 13b, and the anti-slip bolts 14 are provided at three locations spaced apart in the left-right direction of the mat pressing portion 13b.

[0031] Therefore, the tips of the shafts 14b of the three anti-slip bolts 14 spaced apart in the left-right direction of the mat pressing portion 13b can reliably prevent the wiping mat 15 from floating up or shifting, which also makes it possible to reliably clean the tread surface of the rail R, thereby improving the work efficiency of the cleaning work.

[0032] In addition, in the rail tread wiper 1 of the embodiment of the present invention, the tip of the handle bar 11 and the connecting parts 13a, 13a of the mat pressing member are each provided with a connecting hole into which a connecting pin 12 is inserted, and the handle bar 11 and the mat pressing member 12 are configured to be separable by inserting and removing the connecting pin 12.

[0033] Therefore, the rail tread wiper 1 of the embodiment of the present invention can be stored and transported separately from the handle bar 11 and mat pressing member 12, etc., thereby improving storage efficiency and work efficiency, etc. [Explanation of symbols]
