Description

FIELD OF THE INVENTION

The present invention relates to a device for removing foreign material for use in a switch and to a method of installing a device for removing foreign material for use in a switch.

Prior art

Typically, railroad switches are provided with frame rails and wits located close to the frame rails. The turnout is designed so that moving the wits to or from the frame rails allows you to change the direction of movement of the train passing along the turnout. When a turnout is installed, for example, in an area with snowfalls, foreign material, such as frozen snow, can be deposited between the frame rails and wits. If foreign material, such as frozen snow, settles between the frame rails and the wit, the wit may lose the ability to come into contact with the frame rails. In view of the foregoing, Patent Literature 1 (International Patent Publication No. 2013/038657) and Patent Literature 2 (Japanese Patent Publication No. 2000-144602) provide devices for removing foreign material to remove foreign material from the space between the frame rails and the wit.

The foreign material removal device described in Patent Literature 1, as shown in FIG. 11 is provided with a connecting portion 74 extending from the side opposite to the pin 72 with respect to the frame rail 71, to an area lower than the lower surface 73 of the frame rail 71; a curved part 75 attached to the end of the connecting part 74 on the side of the pin 72 and a nozzle part 76 connected to the curved part 75 and located between the frame rail 71 and the pin 72. The device for removing foreign material described in Patent Literature 1 is made as follows so that compressed air supplied from the air reservoir in the form of an external device to the connecting part 74 is injected through the nozzle part 76 through the curved part 75. In this way, foreign material such as frozen snow is deposited minutes between the frame rails 71 and 72 point blades.

The device for removing foreign material described in Patent Literature 2, as shown in FIG. 12 is provided with part 83 for attaching a tube extending from a side opposite the pin with respect to the frame rail 81 to a region lower than the lower surface 82 of the frame rail 81; a prismatic tube 84 connected to the end of the wig-end portion 83 for attaching the tube and extending along the length direction of each rail between the frame rail 81 and the wit; and a nozzle portion formed in the prism tube 84. The tube attachment portion 83 is divided into one portion 83a and another portion 83b in a region lower than the bottom surface 82 of the frame rail 81. One portion 83a and the other portion 83b are attached to each other by screw elements 85. In the device for removing foreign material described in Patent Literature 2, compressed air supplied from a source of compressed air as an external device to the tube connecting portion 83 is injected through the nozzle portion through a prismatic tube SCU 84. Thus, foreign matter is removed, such as frozen snow deposited between the frame rails 81 and the point blades.

In the device for removing foreign material described in Patent Literature 1, for example, when the connecting part 74, the curved part 75 and the nozzle part 76 are formed as a whole, it is difficult to install the device for removing foreign material on the turnout switch. In particular, when the distance between the frame rail 71 and the pin 72 is relatively narrow, it is difficult to insert the connecting part 74 of the device for removing foreign material formed as a whole from the connecting part 74, the curved part 75 and the nozzle part 76, in a region lower than the lower the surface 73 of the frame rail 71 from the space between the frame rail 71 and the wit 72. As a method of installing a device for removing foreign material formed as a whole from the connecting part 74, the curved part 75 and the nozzle portion 76, in turnout, a method is provided in which the operator inserts the nozzle portion 76, the curved portion 75 and the connecting portion 74 into the region lower than the frame rail 71, from the side opposite to the pin 72, with respect to the frame rail 71 and then the operator installs the nozzle portion 75 between the frame rail 71 and the wit 72. However, when the switch is mounted, for example, on a solid rail base, it is difficult to insert the nozzle portion 76 and the curved portion 75 into a space lower than the lower surface 73 of the frame rail 71 because the space is narrow.

Moreover, in the foreign material removal apparatus described in Patent Literature 2, the tube attachment portion 83 is divided into one portion 83a and the other portion 83b in a region lower than the bottom surface 82 of the frame rail 81. Therefore, when the foreign matter remover is the material described in Patent Literature 2, for example, is mounted on a railroad switch, the operator places one part 83a, a prismatic tube 84 and made with it as a single nozzle part in a predetermined installation position from the side between the frame rail 81 and wit. The operator then inserts the other part 83b into the region lower than the frame rail 81, from the side opposite the wit, with respect to the frame rail 81. According to this configuration, it is easy for the operator to install a device for removing foreign material on the switch, even when the space is lower than the lower surface 82 of the frame rail 81 is narrow. However, when the device for removing foreign material described in Patent Literature 2 is mounted on a rail using the aforementioned method, it is necessary to attach one part 83a to another part 83b by means of screw elements 85 in an area lower than the lower surface 82 of the frame rail 81. This may decrease work efficiency.

Summary of the invention

In view of the foregoing, it is an object of the invention to provide a device for removing foreign material for use in a switch, while facilitating installation while preventing a decrease in operating efficiency, and a method for installing a device for removing foreign material for use in a switch.

A device for removing foreign material for use in a turnout according to an aspect of the invention is a device for removing foreign material for use in a turnout, the device for removing foreign material provided with a frame rail and a wit located close to the frame rail and made to move to to the frame rail and from it.

As shown in FIG. 4 and FIG. 5, the intermediate portion 43 includes a first protrusion 43a and a second protrusion 43b. The first protrusion 43a extends vertically in one direction. The second protrusion 43b protrudes to the side opposite the first protrusion 43a. In particular, the first protrusion 43a and the second protrusion 43b are arranged so as to be rotated from each other with a phase angle of 180 ° about the axis of the input element 4. In an embodiment, the first protrusion 43 comes into contact with the lower surface B1, and a U-shaped bolt 61 of the pulling member 6, which will be described later, engages in a second protrusion 43b. The first protrusion 43a and the second protrusion 43b are formed independently of each other and have substantially the same thickness T1.

In an embodiment, the first protrusion 43a projects vertically upward. An embodiment is not limited to the foregoing. The first protrusion 43a may protrude vertically downward. In this case, the second protrusion 43b comes into contact with the lower surface B1, and the U-shaped bolt of the pulling member 6, which will be described later, engages in the first protrusion 43a.

In addition, in the embodiment, the intermediate portion 43 includes two protrusions, i.e., a first protrusion 43a and a second protrusion 43b. An embodiment is not limited to the foregoing. The intermediate portion 43 may include one protrusion or more than two protrusions. In addition, in the embodiment, the first protrusion 43a and the second protrusion 43b are arranged so as to be rotated from each other with a phase angle of 180 ° about the axis of the input element 4. The phase angle between the protrusions is not limited to the above. For example, the protrusions may be arranged to be rotated from each other with a phase angle of 90 °.

The holding plate 5 and the pulling element 6 are elements for attaching the device Y1 for removing foreign material to the frame rail 100.

The holding plate 5 includes a pressing portion 51 and an inclined portion 52. The pressing portion 51 is arranged so as to come into contact with the upper surface of the second sole portion 122. The compression portion 51 is a portion for pressing against the second sole portion 122 from above. The inclined portion 52 is connected to the pressing portion 51. The inclined portion 52 extends from the pressing portion 51 with an inclined downward direction to the side opposite the first sole portion 121 in the width direction of the frame rail 100. The inclined portion 52 is formed with oblong holes 52a and 52b extending along the inclined direction the inclined portion 52. The elongated holes 52a and 52b are formed so as to enclose between them the input element 4 when viewed from above in plan.

The pulling member 6 includes a U-shaped bolt 61 and nuts 62a and 62b. The curved portion of the U-bolt 61 is engaged in the second protrusion 43b, and both ends of the U-bolt 61 are respectively inserted into the elongated holes 52a and 52b. Both ends of the U-shaped bolt 61 inserted into the oblong holes 52a and 52b are respectively secured by nuts 62a and 62b. According to this configuration, the pulling member 6 is attached to the inclined portion 52 in a state in which the U-bolt 61 extends in a direction orthogonal to the inclined portion 52.

The U-shaped bolt 61 applies force to the second protrusion 43b in a state in which the U-shaped bolt 61 is attached to the inclined portion 52 by means of nuts 62a and 62b. According to this configuration, the pulling member 6 pulls the input member 4 to the other side of the end portion 42 in the width direction of the frame rail 100 using the opposing force of the holding plate 5. Since the pulling member 6 pulls on the input member 4, the pulling force is also applied to the output member 2. connected to the input element 4. This allows the opposite part 22a to be pressed against the first sole portion 121, while having a spacer element 3 between them, in the width direction of the frame rail 100. Thus, ivayuschaya plate 5 and the pulling force element 6 opposite part 22a pressed against the first bottom portion 121. Thus, the Y1 device for removing foreign material is mounted on frame rails 100.

The following describes a method of installing a device Y1 for removing foreign material.

1) Location step

First of all, the operator inserts the output element 2 from above into the space between the frame rail 100 and the wit 200. When the operator performs this operation, the operator inserts the lower end 22B of the connecting part 22 into the region lower than the lower surface B1 of the frame rail 100. After that, the operator stops insertion in a position in which the first sole portion 121 faces the opposite portion 22a in the width direction of the frame rail 100. The operator then positions the connecting portion 22 in such a position that the upper end 22A and the lower end z 22B vertically enveloped the first sole portion 121. By performing the above operation, the female thread portion 22b formed at the lower end 22B is positioned to be recessed to a region lower than the lower surface B1 from the pin 200 in the width direction frame rail 100.

2) Connection step

After that, the operator inserts one end part 41 of the input element 4 into the region lower than the lower surface B1, from the side of the second plantar part 122 along the width direction of the frame rail 100, while holding the other end part 42 of the input element 4. When the operator performs this operation, the operator inserts one end part 41 of the input element 4 to the middle part of the connecting part 22 in the length direction of the frame rail 100, while looking at the frame rail 100 and the output element 2 from above. By performing the above operation, the male thread portion 41a is inserted into the female thread portion 22b. After that, when the operator rotates the other end part 42, while holding the other end part 42 outside of the lower surface B1 in plan view, the external thread part 41a is screwed into the internal thread part 22b. By performing the above operation, one end part 41 of the input element 4 is connected to the connecting part 22. In this state, one end part 41 of the input element 4 is held in a state in which one end part 41 does not fall out of the connecting part 22 in the width direction of the frame rail 100. Thus, the input channel 44 open to the external thread portion 41a is in communication with the communication channel 22c open to the internal thread portion 22b.

When the above operation is performed, the operator adjusts the screwing position of the male thread portion 41a with respect to the female thread portion 22b so that the first protrusion 43a projects vertically upward and comes in contact with the lower surface B1. If it is difficult to adjust the axial orientation of the input element 4 so that the first protrusion 43a protrudes vertically upward, the operator can adjust the screwing position of the external thread portion 41a with respect to the internal thread portion 22b so that the second protrusion 43b protrudes vertically upward.

3) Installation phase

After that, the operator places the holding plate 5 so that the pressing part 51 is located above the second plantar part 122 and the inclined part 52 is inclined down to the side opposite the first plantar part 121. Then the operator engages the curved part of the U-bolt 61 for the second protrusion 43b and inserts both ends of the U-bolt 61 into the elongated holes 52a and 52b formed in the inclined portion 52, respectively. After inserting both ends of the U-bolt 61 into the elongated holes 52a and 52b, the operator secures both ends of the U-bolt 61 and nuts 62a and 62b to each other, while holding the U-bolt 61 orthogonally to the inclined portion 52. By performing the above the operation, the U-bolt 61 is fixed in a state in which a pulling force is applied to the input element 4 using the opposing force at the inclined part 52, and the connecting part 22 holding the input element 4 is pressed against the side of the frame rail 100. As a result, In the above operation, the opposite portion 22a is pressed against the first sole portion 121, with the cushion element 3 located therebetween. Thus, the foreign material removal device Y1 is mounted on the frame rail 100 and the installation of the foreign material removal device Y1 is completed.

When the operator secures the U-bolt 61 and nuts 62a and 62b to each other, the operator changes the position of the U-bolt 61 inside the oblong holes 52a and 52b, as necessary, depending on the position of the second protrusion 43b. In particular, when the second protrusion 43b is closer to the connecting portion 22 in the width direction of the frame rail 100, the operator places both ends of the U-bolt 61 in a position closer to the upper ends of the elongated holes 52a and 52b and in this state secures both ends of the U-shaped bolts 61 and nuts 62a and 62b with each other. On the other hand, when the second protrusion 43b is closer to the side opposite the connecting portion 22 in the width direction of the frame rail 100, the operator places both ends of the U-bolt 61 in a position closer to the lower ends of the elongated holes 52a and 52b, and in this state secures both ends of the U-bolt 61 and nuts 62a and 62b with each other. Thus, the operator necessarily changes the relative position between the oblong holes 52a and 52b and the U-shaped bolt 61. This allows you to change the relative position of the U-shaped bolt 61 with respect to the input element 4 depending on the position of the second protrusion 43b. Thus, the U-shaped bolt 61 is attached to the inclined portion 52 in a state in which the inclined portion 52 and the U-shaped bolt 61 are orthogonal to each other.

In the above-described device for removing foreign material Y1, the input element 4 and the connecting part 22 are separated from each other and one end part 41 of the input element 4 is connected to the connecting part 22 in a region lower than the lower surface B1 of the frame rail 100. The other end part 42 of the input element 4 is located outside the lower surface B1 of the frame rail 100 when viewed from above in plan. According to this configuration, the operator who installs the device Y1 for removing foreign material can place the output element 2 in a predetermined installation position from the space between the frame rail 100 and the wit 200 and rotate the other end part 42, while holding the other end part 42 of the input element 4 in the area outside the bottom surface B1 of the frame rail 100 when viewed from above in plan. The operator can then attach one end portion 41 of the input element 4 to the connecting part 22, while inserting the input element 4 into a region lower than the lower surface B1 of the frame rail 100. This allows the operator to more easily perform the installation operation, even when the region is lower than the lower surface B1 of the frame rail 100 is narrow, and eliminates the need for a laborious fastening operation in an area lower than the lower surface B1 of the frame rail 100. An advantage of this is to prevent a decrease in the efficiency of the work Ot.

In addition, in the foreign material removal device Y1, the input element 4 has a rectilinear shape from one end portion 41 to the other end portion 42. Therefore, when the operator installs the foreign material removal device Y1, the operator can easily rotate the other end portion 42 into a state in which the input element 4 is inserted into the region lower than the lower surface B1 of the frame rail 100. This allows the operator to more easily perform the operation of connecting one end part 41 to the connecting part 22, while turning Vai other end portion 42. The advantage of this is to increase the work efficiency.

Moreover, in the foreign material removal device Y1, when the operator installs the foreign material removal device Y1, the operator can easily connect one end portion 41 to the connecting portion 22 by screwing the external thread part 41a to the internal thread part 22b, wherein turning the other end portion 42.

In addition, in the foreign material removal apparatus Y1, the external thread portion 41a and the internal thread portion 22b are located in a region lower than the lower surface B1 of the frame rail 100. This allows the operator to hold one end portion 41 of the input member 4 with respect to the connecting part 22, while effectively using the space lower than the lower surface B1 of the frame rail 100.

In addition, in the foreign material removal apparatus Y1, the external thread portion 41a has a conical shape. This allows the operator to easily adjust the axial orientation of the input element 4 when the operator screws the male thread portion 41a into the female thread portion 22b. In addition, screwing the male threaded conical part 41a into the female threaded part 22b prevents the leakage of compressed air from the space between one end part 41 and the connecting part 22. This eliminates the need for a gasket between one end part 41 and the connecting part 22 and provides the possibility of reducing the number of parts. In particular, in an embodiment, the nozzle portion 21 and the connecting portion 22 of the output element 2 are formed as a unit. Therefore, there is no likelihood of compressed air leaking from any part of the output element 2 except the nozzle openings 21a. An advantage of this is an increase in the efficiency of using compressed air supplied from the compressed air source Z1 to the device Y1 for removing foreign material.

In addition, in the apparatus Y1 for removing foreign material, elongated holes 52a and 52b are formed in the holding plate 5. Changing the position of the U-bolt 61 in the elongated holes 52a and 52b allows you to change the relative position of the U-bolt 61 with respect to the input element 4. According to this configuration, for example, even if a size error occurs in the length of the first sole portion 121 in the width direction of the frame rail 100 and when the position of the second protrusion 43b deviates in a state in which the device for removing foreign material Y1 is attached to the frame rail 100, the operator can stably engage the U-bolt 61 for the second protrusion 43b.

In addition, in the apparatus Y1 for removing foreign material, regardless of the change in position of the U-bolt 61 in the elongated holes 52a and 52b, the operator can attach the U-bolt 61 to the inclined portion 52 in a position in which the U-bolt 61 orthogonal to the inclined portion 52. An advantage of this is the stable attachment of the U-bolt 61 to the inclined portion 52.

In addition, in the apparatus Y1 for removing foreign material, one of the first protrusion 43a and the second protrusion 43b, which protrude in opposite directions, performs the function of a thrust portion with respect to the lower surface B1 of the frame rail 100, and the other of the first protrusion 43a and the second protrusion 43b performs the function of the part engaged with the U-bolt 61. This allows you to reverse the functions of the first protrusion 43a and the second protrusion 43b depending on the orientation of the input element 4 and allows the operator to easily install the input element 4. In For example, if only the first protrusion 43a is provided from the first protrusion 43a and the second protrusion 43b, which functions as a stop part, and if the position of the first protrusion 43a with respect to the lower surface B1 of the frame rail 100 deviates, the operator must adjust the first protrusion 43a to the proper position by turning and securing the male thread portion 41a with respect to the female thread portion 22b. In this case, the operator must rotate the male thread portion 41a as much as possible by an angle close to 360 °. In contrast to the above case, in the device Y1 for removing foreign material, when the use of the first protrusion 43a as the abutting part of the frame rail 100 is difficult due to the deviation of the position of the first protrusion 43a with respect to the lower surface B1 of the frame rail 100, the operator can adjust the second the protrusion 43b to the corresponding position as the abutment portion of the frame rail 100 by turning and securing the external thread portion 41a with the internal thread portion 22b. In this configuration, the rotation amount of the external thread portion 22b is at most 180 ° or less. Therefore, in comparison with the case mentioned above, in which it is necessary to rotate the external thread portion 41a by an angle close to 360 °, the operator can perform the installation operation with less force.

In addition, in the device Y1 for removing foreign material, the provision of a cushioning element 3 between the first sole portion 121 and the opposite portion 22a, depending on the production error of the size of the frame rail 100, allows you to set the optimal relative position of the nozzle portion 21 with respect to the main body 110 of the rail.

In addition, in the apparatus Y1 for removing foreign material, a gap S1 is formed between the first side surface 111a of the frame rail 100 and the nozzle part 21. This makes it possible to reduce the likelihood of transmission of vibrations arising from the train to the nozzle part 21 through the frame rail 100. Advantage this is to prevent stress concentration on the connecting part between the nozzle part 21 and the connecting part 22 due to the transmission of vibrations. In the above configuration, there is no need for a final adjustment of the position of the nozzle part 21, so that the nozzle part 21 comes into contact with the first side surface 111a depending on the production error of the size of the frame rail 100. This allows the operator to more easily perform the installation operation of the device Y1 for removing foreign material.

In an embodiment, the operator connects one end portion 41 to the connecting portion 22 by screwing the outer thread portion 41a to the inner thread portion 22b. An embodiment is not limited to the foregoing. The male thread portion 41a and the female thread portion 22b may be omitted.

For example, a fitting hole may be formed in the surface of the lower end 22B from the input element 4 side of the connecting portion 22 in the width direction of the frame rail 100. Inserting one end portion 41 into the fitting hole allows the operator to connect one end portion 41 to the connecting portion 22 .

In addition, the operator can connect one end part 41 to the connecting part 22 using a tubular connecting element. The tubular connecting element consists of two parts. The operator installs one part of the tubular connecting element to one end part 41 and installs the other part of the tubular connecting element to the connecting part 22. In this state, the operator inserts one end part 41 into the region lower than the lower surface B1 of the frame rail 100, while holding the other end part 42, and connects one part and another part of the tubular connecting element to each other in a region lower than the lower surface B1. By performing the above operation, one end portion 41 is connected to the connecting portion 22.

In addition, in the modification illustrated in FIG. 6, the connecting portion 22 includes a through hole 22d, instead of an internal thread portion 22b, and the input member 4 includes a flange portion 45, instead of an external thread portion 41a.

The through hole 22d is formed as part of the connecting portion 22 in a region lower than the lower surface B1 of the frame rail 100. The through hole 22d passes through the lower end 22B in the width direction of the frame rail 100. The communication channel 22c is open to the upper part of the inner surface of the lower end 22B, forming through hole 22d.

The flange portion 45 is formed at the end of one end portion 41 of the input element 4. The input channel 44 is open to the upper part of the outer surface of the input element 4 on the other side of the end portion 42 with respect to the flange portion 45. The diameter of the flange portion 45 is larger than the diameter of the through hole 22d . In addition, a portion of the input element 4 that is not the flange portion 45 has a slightly smaller diameter than the diameter of the through hole 22d.

The input element 4 is inserted into the through hole 22d, and the flange portion 45 comes into contact with the surface of the lower end 22B from the side of the pin 200. According to this configuration, the input element 4 is connected to the connecting part 22. In this state, the input element 4 is held in a state in which one end portion 41 does not fall out of the connecting portion 22 on the side opposite to the pin 200, while having the frame rail 100 between them in the width direction of the frame rail 100. In addition, in this state, the communication channel 22c is open to the top parts of the inner surface of the lower end 22B, and the input channel 44, open to the upper part of the outer surface of the input element 4, communicate with each other.

In the modification illustrated in FIG. 6, in order to connect the input element 4 to the connecting part 22, the operator inserts the other end part 42 into the through hole 22d from the pin 200 in a state in which the flange part 45 is held. The operator then holds the other end portion 42, which extends the lower surface B1 of the frame rail 100 outward, on the side opposite to the pin 200 with respect to the frame rail 100, and pulls the other end portion 42. By performing the above operation, the flange portion 45 is brought into contact with the surface of the lower end 22B from the side of the pin 200.

As described above, in the modification illustrated in FIG. 6, after inserting the other end part 42 into the through hole 22d, the operator holds the other end part 42 outside the bottom surface B1 in plan view and pulls the other end part 42. By performing the above operation, the operator can bring the flange part 45 in contact with the surface the lower end 22B from the side of the pin 200 and can connect one end portion 41 to the connecting portion 22.

Alternatively, as shown in FIG. 7, the connecting portion 22 may include a recessed portion 22e instead of a through hole 22d. The recessed portion 22e is formed in the same position as the through hole 22d. The recessed portion 22e is formed to be recessed upward. In this case, the operator holds the other end portion 42, located outside the lower surface B1, on the side opposite to the pin 200 with respect to the frame rail 100, in a state in which part of the input element 4 is inserted into the region lower than the lower surface B1, and lifts up the input element 4 to engage the input element 4 in the recessed portion 22e. The operator can then connect one end portion 41 to the connecting portion by bringing the flange portion 45 into contact with the surface of the lower end 22B from the pin 200 in a state in which the input member 4 is engaged in the recessed portion 22e.

In addition, in the modifications illustrated in FIG. 8 and FIG. 9, the input element 4 includes a first convex portion 46 and a second convex portion 47, instead of an external thread portion 41a. The connecting portion 22 includes an opening 22f instead of a female thread portion 22b. In FIG. 8, an illustration of the frame rail 100 is omitted to simplify the description. FIG. 9 is a front view of the surface of the lower end 22B from the input element 4 side of the connecting portion 22 illustrated in FIG. 8, in the width direction of the frame rail 100.

A first convex portion 46 is formed at the end of one end portion 41. A first convex portion 46 is formed radially in some direction from one end portion 41. A second convex portion 47 is formed at the end of one end portion 41. A second convex portion 47 extends radially from one end portion 41 in the opposite direction to the first convex portion 46.

The hole 22f is configured so that a portion of the surface of the lower end 22B from the side of the input member 4 is recessed to the side of the pin 200 in the width direction of the frame rail 100. The hole 22f includes a first concave portion 22g and a second concave portion 22h. The first concave portion 22g is the insertion portion of the first convex portion 46 when the operator inserts one end portion 41 into the hole 22f. The second concave portion 22h is the insertion portion of the second convex portion 47 when the operator inserts one end portion 41 into the hole 22f.

The lower end 22B of the connecting portion 22 includes a first groove portion 22i and a second groove portion 22j. In particular, the first groove portion 22i is configured so that a portion of the end of the hole 22f on the side of the pin 200 is radially recessed. The circumferential end of the first groove portion 22i is connected to the first concave portion 22g. The width of the first groove portion 22i is formed so that it is slightly larger than the thickness of the first convex portion 46. In addition, the second groove portion 22j is configured so that a portion of the end of the hole 22f from the point of the pin 200 is radially recessed. The second groove portion 22j is formed radially on the side opposite the first groove portion 22i. The circumferential end of the second groove portion 22j is connected to the second concave portion 22h. The width of the first groove portion 22i is formed so that it is slightly larger than the thickness of the second convex portion 47.

When the operator installs the foreign material removal apparatus Y1 according to the modifications illustrated in FIG. 8 and FIG. 9, the operator inserts one end part 41 of the input element 4 into the region lower than the lower surface B1, while holding the other end part 42 outside the lower surface B1 when viewed from above in plan. Then, the operator inserts one end portion 41 of the input member 4 into the hole 22f, while positioning the first convex portion 46 with respect to the first concave portion 22g and positioning the second convex portion 47 with respect to the second concave portion 22h. Finally, when one end portion 41 reaches the end of the hole 22f from the point of the pin 200, the operator rotates the other end portion 42 in the direction of the arrow A1 shown in FIG. 9, outside the bottom surface B1 in plan view from above. By performing the above operation, the first convex portion 46 is engaged in the first groove portion 22i, and the second convex portion 47 is engaged in the second groove portion 22j.

As described above, in the modifications illustrated in FIG. 8 and FIG. 9, when the operator rotates the other end portion 42 from the outside of the lower surface B1 in plan view, the operator can engage the first convex portion 46 in the first groove portion 22i and engage the second convex portion 47 in the second groove portion 22j. This allows the operator to connect one end portion 41 to the connecting portion 22.

In addition, in the modification illustrated in FIG. 10, the frame rail 100 comes into contact with the input element 4 and with the connecting part 22 at three points. Moreover, in the modification illustrated in FIG. 10, the connecting portion 22 comes into contact with the first sole portion 121 from above at two points spaced apart in the width direction of the frame rail 100. The following is a detailed description of the modification.

The input element 4 comes into contact with the sole portion 120 at the first protrusion 43a from the bottom of the sole portion 120. In particular, the input element 4 comes into contact with the frame rail 100 at one point from the bottom of the frame rail 100.

The upper end 22A of the connecting part 22 includes a tip 22m and a main end 22n as two ends of the upper end 22A in the width direction of the frame rail 100. The tip 22m is located on the side of the first part 111 and is connected to the nozzle part 21 through the connecting part 22C in the width direction of the frame rail 100. The main end 22n is located on the side opposite to the tip 22m and is connected to the opposite part 22a in the width direction of the frame rail 100. The tip 22m comes into contact with the upper surface of the portion of the first plantar h STI 121 on the side of the first end portion 111. The main 22n comes into contact with the upper surface of the first part of the bottom portion 121 on the side opposite portion 22a. In particular, the upper end 22A of the connecting portion 22 comes into contact with the frame rail 100 on top of the frame rail 100 at two points spaced apart from one another in the width direction of the frame rail 100.

In an embodiment, the upper end 22A of the connecting portion 22 does not come into contact with a portion of the first sole portion 121 on the side of the first portion 111 and only comes into contact with a portion of the first sole portion 121 on the side opposite to the portion 22a. On the other hand, in the modification illustrated in FIG. 10, the tip 22m of the upper end 22A of the connecting portion 22 comes into contact with a portion of the first sole portion 121 on the side of the first portion 111 in an area vertically lower than the nozzle portion 21. In particular, in the modification illustrated in FIG. 10, the connecting portion 22 comes into contact with the sole portion 120 of the frame rail 100 on the side closer to the nozzle portion 21, in comparison with the embodiment.

In addition, in the modification illustrated in FIG. 10, unlike the embodiment, the spacer element 3 is not provided. Therefore, in the modification illustrated in FIG. 10, a gap is formed between the first sole portion 121 and the opposite portion 22a in the width direction of the frame rail 100. Alternatively, the first sole portion 121 and the opposite portion 22a may come into contact with each other in the width direction of the frame rail 100.

As described above, in the modification illustrated in FIG. 10, the input element comes into contact with the frame rail 100 from below the frame rail 100, and the connecting part 22 comes into contact with the frame rail 100 from above the frame rail 100. According to this configuration, the frame rail 100 is between the input element 4 and the connecting part 22. Therefore , the operator can easily stably install the device Y1 for removing foreign material on the frame rail 100. In addition, in the modification illustrated in FIG. 10, the device Y1 for removing foreign material comes into contact with the sole portion 120 at three points so that the sole portion 120 is vertically between the upper and lower sides. An advantage of this is the stable installation of the device Y1 for removing foreign material on the frame rail 100.

Moreover, in the modification illustrated in FIG. 10, the tip 22m of the upper end 22A connected to the connecting portion 22C comes into contact with the first sole portion 121 of the frame rail 100. In particular, in the modification illustrated in FIG. 10, the connecting portion 22 comes into contact with the sole portion 120 of the frame rail 100 in a region vertically lower than the nozzle portion 21. A portion of the output member 2 on the side of the nozzle portion 21 with respect to the tip 22m, in other words, the connecting portion 22C and the nozzle portion 21, are in a console state. In the modification illustrated in FIG. 10, it is possible to bring the point of contact between the connecting portion 22 and the frame rail 100 closer to the nozzle portion 21. This makes it possible to shorten the length of the connecting portion 22C in the position of the connecting portion 22C and the nozzle portion 21 in the cantilever state. This makes it possible to reduce the displacement of the nozzle part 21 due to vibrations and to reduce the load on the nozzle part 21. In particular, it is possible to reduce the maximum load on the nozzle part 21 by about 40% and increase the safety factor by two or more compared to the embodiment. Thus, it is possible to reduce the likelihood of damage to the nozzle portion 21 due to vibrations.

In addition, in the modification illustrated in FIG. 10, the connecting portion 22 comes into contact with the frame rail 100 at two points, that is, at the tip 22m and at the main end 22n, spaced apart in the width direction of the frame rail 100. This allows the operator to easily install the device Y1 to remove foreign material when the operator sets the device Y1 to remove foreign material on the turnout X1.

In addition, in the modification illustrated in FIG. 10, bringing the two points, that is, the tip 22m and the main end 22n, into contact with the frame rail 100 allows the connecting portion 22 to be stably mounted on the frame rail 100. Therefore, it is not necessary to provide a spacer element 3. This reduces the number of parts.

In addition, in the modification illustrated in FIG. 10, bringing the tip 22m of the connecting portion 22 into contact with a portion of the first sole portion 121 on the side of the first portion 111 reduces the likelihood of damage to the nozzle portion 21. The advantage of this is that the structure of the apparatus Y1 for removing foreign material is compact.

In the modification illustrated in FIG. 10, the connecting portion 22 is arranged to be in contact with the frame rail 100 on top of the frame rail 100 at two points, i.e., at the tip 22m and at the main end 22n. Alternatively, the foreign material removal device Y1 may be configured such that the input member 4 comes into contact with the frame rail 100 at least at one point, the connecting portion 22 comes into contact with the frame rail 100 at least at one point, and the input element 4 and the connecting part 22 came into contact with the frame rail 100 at least at three points. This makes it possible to stably mount the foreign material removal device Y1 with respect to the frame rail 100. For example, the connecting portion 22 can be brought into contact with the frame rail 100 at one point on top of the frame rail 100, and the lower end 22B illustrated in FIG. 10 may be brought into contact with the frame rail 100 from below the frame rail 100 by contact between the lower end 22B and the lower surface B1. In this case, the device Y1 for removing foreign material comes into contact with the frame rail 100 at two points from the bottom of the frame rail 100 and comes into contact with the frame rail 100 at one point on top of the frame rail 100. This allows you to stably install the device Y1 for removing foreign material at in relation to the frame rail 100. In the modification illustrated in FIG. 10, the foreign material removal apparatus Y1 comes into contact with the frame rail 300 at three points. Alternatively, the foreign material removal device Y1 may come into contact with the frame rail 100 at four or more points. For example, the device Y1 for removing foreign material can be brought into contact with the frame rail 100 at four points, that is, at the tip 22m, at the main end 22n, at the lower end 22B and at the first protrusion 43a.

The embodiment and modifications described above should be understood as illustrative in all respects and not limiting. The scope of the present invention is determined not by describing the above embodiment and modifications, but by the scope of the claims and includes all changes within the essence and range of equivalents of the scope of the claims.

For example, in the embodiment and the modifications, the holding plate 5 has a curved shape between the pressing portion 51 and the inclined portion 52, and the pressing portion 51 and the upper surface of the second sole portion 122 come into flat contact with each other. Alternatively, the holding plate 5 may be flat in shape without a curved portion. In this case, the holding plate 5 in the form of a flat plate is inclined so that the holding plate 5 is located between the upper surface of the input element 4 and the upper surface of the end of the second sole portion 122 and comes into contact with the second sole portion 122.

In addition, in an embodiment, after the operator places the output element 2 at a predetermined position near the frame rail 100, the operator inserts one end portion 41 of the input element 4 into the region lower than the lower surface B1, from the side of the second sole portion 122 and connects one end a portion 41 with a connecting portion 22. Alternatively, for example, when the space is lower than the lower surface B1 of the frame rail 100 is large enough or when it is possible to increase the space by digging the ballast under the lower surface B1 of the frame rail 100, it is possible to position the input element 4 in a region lower than the frame rail 100, in a state in which the input element 4 is connected to the output element 2, and then attach the input element 4 to the frame rail 100.

In this case, first of all, the operator connects one end part 41 of the input element 4 to the connecting part 22 by screwing the external thread part 41a to the internal thread part 22b. The operator then arranges the connecting body of the output member 2 and the input member 4 so that the input member 4 is inserted into the region lower than the lower surface B1 from the side of the first plantar portion 121 and that the nozzle portion 21 is inserted from the bottom of the pin 200 into the space between the pin 200 and the frame rail 100. Thus, after the operator places the output element 2 and the input element 4 at a predetermined position near the frame rail 100, the operator places the U-shaped bolt 61, catching it on the second protrusion 43b. The operator then inserts both ends of the U-bolt 61 into the elongated holes 52a and 52b of the holding plate 5 to attach the U-bolt 61 to the holding plate 5 by means of nuts 62a and 62b. Thus, the device Y1 for removing foreign material is mounted on the frame rail 100.

The following is a brief description of an embodiment.

The aforementioned device for removing foreign material for use in a turnout is a device for removing foreign material for use in a turnout, in which a device for removing foreign material is provided with a frame rail and a wit located close to the frame rail and configured to move to to the frame rail and from it. A device for removing foreign material is provided with an input element including an input channel for supplying a substance that removes foreign material, the input element extending in the direction of the width of the frame rail in the region lower than the lower surface of the frame rail, and the connecting part including the channel messages for communicating a nozzle portion that injects a substance removing foreign material into the space between the frame rail and the wit, and the inlet channel. The connecting part is connected to one end part of the input element in an area lower than the lower surface of the frame rail. The other end part of the input element, located outside the lower surface of the frame rail when viewed from above in plan, is designed so that the operator can connect one end part of the input element to the connecting part.

In a device for removing foreign material for use in turnouts, the input element and the connecting part are separated from each other, and one end part of the input element is connected to the connecting part in an area lower than the lower surface of the frame rail. The other end part of the input element is located outside the bottom surface of the frame rail when viewed from above in plan. According to this configuration, the operator who installs the device for removing foreign material can place the connecting part in a predetermined installation position from the space between the frame rail and the pin and actuate the other end part of the input element in the area outside the bottom surface of the frame rail when viewed from above in plan . Then the operator can connect one end part of the input element with the connecting part, while inserting the input element in the region lower than the lower surface of the frame rail. As described above, in the device for removing foreign material for use in turnout, the input element and the connecting part are separated from each other. Therefore, even when the space is lower than the lower surface of the frame rail is narrow, the operator can easily install a device for removing foreign material. Moreover, there is no need to perform a difficult attachment operation in an area lower than the lower surface of the frame rail. The advantage of this is to prevent a decrease in work efficiency.

Preferably, the input element may have a rectilinear shape from one end part to the other end part.

In a device for removing foreign material for use in a turnout, when an operator installs a device for removing foreign material, the operator can easily rotate the other end portion of the input element in a state in which the input element is inserted into an area lower than the lower surface of the frame rail. Therefore, the operator can easily carry out the operation of connecting one end part of the input element with the connecting part, while turning the other end part of the input element. The advantage of this is an increase in work efficiency.

Preferably, the connecting portion may include a female thread portion. In this case, preferably, one end part of the input element may include an external thread part adapted to be screwed into the internal thread part.

In a device for removing foreign material for use in turnouts, when the operator installs a device for removing foreign material, the operator can easily connect one end part of the input element to the connecting part by screwing a part with an external thread into a part with an internal thread, while turning the other end part of the input element.

Preferably, the threaded portion may be tapered to the end of one end portion.

In the device for removing foreign material for use in turnout, the part with an external thread has a conical shape. Therefore, when an operator screws an external thread part into a female thread part, the operator can easily adjust the axial orientation of the input element. In addition, screwing a conical part with an external thread into a part with an internal thread helps prevent leakage of a foreign material removing substance from the space between one end part of the input element and the connecting part. Therefore, there is no need to provide gaskets between one end part of the input element and the connecting part. This reduces the number of parts.

Preferably, the frame rail may include a vertically extending main body of the rail and a sole portion connected to a lower end of the main body of the rail, the sole portion including a first sole portion extending from the main rail body to the pin side and a second sole portion extending to the side opposite the first plantar. In this case, preferably, the connecting portion may include an opposing portion that faces the first sole portion in the width direction of the frame rail. Preferably, the device for removing foreign material may further include a retaining plate mounted on the second plantar portion; and a pulling element engaged with the input element and exerting a pulling force on the input element so that the opposite part is pressed against the first plantar part using the opposing force of the holding plate. In this case, preferably, the holding plate can hold the pull member so that the relative position of the pull member with respect to the input member is variable in the width direction of the frame rail.

In a device for removing foreign material for use in turnouts, the input element and the connecting part holding the input element are attracted by the pulling element to the side opposite the wit in the width direction of the frame rail. This presses the opposite part against the first plantar part and fixes the relative position of the connecting part and the nozzle part with respect to the frame rail. If during the manufacturing process of the frame rail there is a dimensional error in the length of the first plantar part in the width direction of the frame rail, the position of the input element in the width direction may deviate in a state in which the opposite part is pressed against the first plantar part. If the position of the input element in the width direction of the frame rail deviates, the tension position of the pulling element with respect to the input element may also be deviated. In the device for removing foreign material for use in turnouts, it is possible to change the relative position of the pulling element with respect to the input element in the width direction of the frame rail. Therefore, it is possible to change the relative position of the pulling element with respect to the input element in accordance with the deviation of the engagement position. Thus, it is possible to hold the pulling element on the holding plate, the relative position of which changes. According to this configuration, even if there is a manufacturing error in the size of the frame rail, it is possible to stably fix the device for removing foreign material with respect to the frame rail.

Preferably, the input element may include, in a region lower than the lower surface of the frame rail, a first protrusion and a second protrusion protruding to a side opposite the first protrusion. In this case, preferably, one of the first protrusion and the second protrusion can be brought into contact with the lower surface of the frame rail, and the other of the first protrusion and the second protrusion can be engaged by the pulling member.

In a device for removing foreign material for use in a railroad switch, one of the first protrusion and the second protrusion, which protrude in opposite directions to each other, performs the function of a thrust part with respect to the lower surface of the frame rail, and the other of the first protrusion and the second protrusion performs the function parts engaged by the pulling element. This allows, if necessary, to invert the functions of the first protrusion and the second protrusion depending on the orientation of the input element. This allows the operator to easily position the input element.

Preferably, a device for removing foreign material can be further provided with a cushioning element located between the first plantar part and the opposite part.

In the device for removing foreign material for use in turnouts, the provision of a cushioning element between the first plantar part and the opposite part, depending on the production error of the frame rail size, allows you to set the relative position of the nozzle part relative to the main body of the rail in the optimal position.

Preferably, the nozzle portion may be located between the frame rail and the wit. In this case, preferably, a gap can be formed between the nozzle portion and the frame rail.

The device for removing foreign material for use in the turnout is designed so that the nozzle portion is brought into reliable contact with the frame rail. This eliminates the need for fine adjustment of the relative position of the nozzle part with respect to the frame rail, depending on the production error of the size of the frame rail.

A method of installing a device for removing foreign material for use in a railroad switch according to the invention is to install a device for removing foreign material for use in a switchboard, in which a device for removing foreign material is provided with a frame rail and a wit located close to the frame rail and made with the ability to move to and from the frame rail. The method includes an arrangement step in which the connecting portion is arranged in such a position that at least a portion of the connecting portion is located in a region lower than the lower surface of the frame rail, the connecting portion including a communication channel for communicating with the nozzle portion, which injects a substance to remove foreign material, and a connection step, in which the operator can actuate the other end part of the input element, including the input channel for communication with the communication channel and for supplying a substance to remove foreign material outside the bottom surface of the frame rail when viewed from above in plan so that the operator can connect one end part of the input element with the connecting part in a region lower than the lower surface of the frame rail, while inserting the input element to an area lower than the lower surface of the frame rail.

In a method of installing a device for removing foreign material for use in a turnout, the input element and the connecting part are separated from each other. The operator can insert the input element into the area lower than the lower surface of the frame rail, while placing the connecting part in a predetermined installation position from the space between the frame rail and the wit. This allows the operator to easily install a device for removing foreign material, even when the space is lower than the lower surface of the frame rail, is narrow. In addition, the operator can connect one end part of the input element to the connecting part by actuating the other end part of the input element in the area outside the bottom surface of the frame rail when viewed from above in plan. This eliminates the need for a laborious attachment operation in an area lower than the lower surface of the frame rail. The advantage of this is to prevent a decrease in work efficiency.
