Description

  The present invention relates to a branching device tongue position adjusting tool for adjusting the position of a tongrel relative to a basic rail in a branching device.

  Branches are installed in the railway. The branching device has a track structure that divides the track into two or more (see 4.a of Non-Patent Document 1). The turnout has points. The point is the device of the part that divides the trajectory among the parts constituting the branching unit (see 4.b of Non-Patent Document 1). As shown in FIG. 7, the branch point has a basic rail R1 and a tongrel R2. In addition, in FIG. 7, the fastening device which fastens a rail to a sleeper is abbreviate | omitting illustration. The tongue rail R2 is a rail that has a pointed head and is converted (see 4.e of Non-Patent Document 1). The basic rail R1 is a rail with which the Tongrel R2 comes into contact (see 4.e of Non-Patent Document 1).

  In maintenance of the branching device, the Tongleil R2 may be exchanged or the interval between the left and right Tongleyl R2 may be adjusted. At that time, the rolling bar S1 and the holding bar S2 are removed from the Tongrel R2. The rolling rod S1 is a rod attached to the Tongrel R2 in order to connect to the conversion device (see 4.f of Non-Patent Document 1, and accompanying drawings of Non-Patent Document 2). The holding rod S2 is a rod that connects the left and right Tongrel R2 in order to reduce the lateral deflection of the Tongrel R2 (see 4.f of Non-Patent Document 1, attached drawing of Non-Patent Document 2, and Patent Document 1). The rolling bar S1 and the holding bar S2 are respectively bolted to the Tongrel R2 via a connecting plate. The connecting plate is a metal fitting that is attached to the Tongrel R2 in order to attach the rolling bar S1 or the holding bar S2 (refer to 4.f of Non-Patent Document 1, and attached drawings of Non-Patent Document 2).

  When the retaining rod S2 is removed from the Tongrel R2, the Tongrel R2 moves in the sleeper direction (horizontal direction orthogonal to the Tongrel R2) and changes its position with respect to the basic rail R1. When the position of the tongrel R2 with respect to the basic rail R1 changes, the position of the bolt hole for passing the bolt connecting the reserving bar S2 and the connecting plate S21 shifts, and the reserving bar S2 cannot be bolted to the connecting plate S21. . Conventionally, the Tonglerail R2 is moved using a railway bar for track maintenance work, and the position of the Tongrel R2 with respect to the basic rail R1 is adjusted. However, it is not easy to adjust the position of the Tongrel R2 with respect to the basic rail R1 using the rail bar.

  A branching tongue position adjuster according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the branching device tong position adjusting tool 1 is an instrument for adjusting the position of the tongrel R2 relative to the basic rail R1 in the branching device. Since the branching device tongue adjustment tool 1 is made of metal, it is also called a branching device tongue position adjustment fitting. In addition, the branching device tongue position adjusting tool 1 is mainly used in the vicinity of the holding rod S2 (see FIG. 7).

  The branching device tongue position adjusting tool 1 includes a pair of push plates 2a and 2b and a distance adjusting rod 3 (see FIG. 1). The push plates 2a and 2b are parts for pushing the head side surface of the rail. The distance adjusting rod 3 is a component that adjusts the distance d between the pair of push plates 2a and 2b. One push plate 2a has a female screw 21a which is a positive screw (right screw). The other pressing plate 2b has a female screw 21b of a reverse screw (left screw). The distance adjusting rod 3 includes a screw portion 31a that is screwed into the female screw 21a of one push plate 2a, and a screw portion 31b that is screwed to the female screw 21b of the other push plate 2b. The mutual distance d of the pair of push plates 2a and 2b changes as the distance adjusting rod 3 is turned.

  The shape of the one pressing plate 2a and the other pressing plate 2b is symmetrical to each other in a side view. That is, the three-dimensional shapes of the push plate 2a and the push plate 2b are in a mirror image relationship. The pressing plate 2a and the pressing plate 2b are collectively referred to as the pressing plate 2. The female screw 21a and the female screw 21b are collectively referred to as a female screw 21.

  The interval adjusting rod 3 passes through the push plate 2.

  As shown in FIGS. 2 and 3, each push plate 2 includes a plate portion 22 having a contact surface 221 that is brought into contact with the side surface of the head of the rail, and a nut portion 23 in which a female screw 21 is formed. In the pressing plate 2, the nut portion 23 protrudes on the side where the contact surface 221 is present, and the surface 222 opposite to the contact surface 221 is flat.

  As shown in FIGS. 4 and 5, the distance adjusting rod 3 has a bar shape that is symmetrical in a side view. The space | interval adjustment stick | rod 3 has the prismatic part 32 formed in the center part at the regular hexagonal prism. The rectangular column portion 32 is a portion that is gripped by a tool such as a wrench when the interval adjusting rod 3 is rotated. The interval adjusting rod 3 is formed with threaded portions 31 a and 31 b on both sides of the prism portion 32. The screw portion 31a that is screwed into the female screw 21a of the positive screw is a male screw of the positive screw (see FIG. 1). The screw portion 31b that is screwed into the female screw 21b of the reverse screw is a male screw of the reverse screw. When the distance adjusting rod 3 is turned clockwise while the push plate 2b is viewed on the front side, the mutual distance d between the push plates 2a and 2b is reduced, and when the distance adjusting rod 3 is turned counterclockwise, the distance between the push plates 2a and 2b is reduced. The mutual distance d increases.

  Since the interval adjusting rod 3 penetrates the push plate 2, as shown in FIG. 6, the branching device tongue position adjuster 1 is configured by reversing the directions of the push plates 2 a and 2 b with respect to the interval adjusting rod 3. be able to.

  A configuration for moving the Tongrel R2 away from the basic rail R1 (see FIG. 1) and a configuration for bringing the Tongler R2 closer to the basic rail R1 by reversing the direction of the push plates 2a, 2b with respect to the interval adjusting rod 3 (see FIG. 1). (See FIG. 6).

  The plate portion 22 has a protrusion 24 that protrudes toward the abdomen of the rail to be pressed. The rail to be pushed is the basic rail R1 or the tongrel R2.

  The usage of the branching device tongue position adjusting tool 1 configured as described above will be described. When the tongue rail R2 is moved away from the basic rail R1, the push plates 2a and 2b are attached to the distance adjusting rod 3 so that the two contact surfaces 221 face outward (see FIG. 1). The distance adjusting rod 3 is turned to reduce the mutual distance d between the push plates 2a and 2b, and the pair of plate portions 22 are placed between the basic rail R1 and the tongrel R2. The distance adjusting rod 3 is turned to enlarge the mutual distance d between the pressing plates 2a and 2b. The tongue rail R2 is displaced in the direction indicated by the white arrow, and the position with respect to the basic rail R1 is adjusted. When the rotation of the distance adjusting rod 3 is stopped, the distance d between the push plates 2a and 2b is kept constant. When removing the branching device tongue position adjusting tool 1, the distance adjusting rod 3 is turned to reduce the mutual distance d between the push plates 2a and 2b.

  When the tongue rail R2 is brought close to the basic rail R1, the pressing plates 2a and 2b are attached to the distance adjusting rod 3 so that the two contact surfaces 221 face each other (see FIG. 6). The distance adjustment rod 3 is turned to increase the mutual distance d between the push plates 2a and 2b, and the pair of plate portions 22 sandwich the basic rail R1 and the tongrel R2. The distance adjusting rod 3 is turned to reduce the mutual distance d between the push plates 2a and 2b. The tongue rail R2 is displaced in the direction indicated by the white arrow, and the position with respect to the basic rail R1 is adjusted. When the rotation of the distance adjusting rod 3 is stopped, the distance d between the push plates 2a and 2b is kept constant. When removing the branching device tongue position adjusting tool 1, the distance adjusting rod 3 is turned to enlarge the mutual distance d between the push plates 2a and 2b.

  As described above, according to the branching device tongue position adjuster 1 according to the present embodiment, the distance d between the pair of push plates 2a and 2b for pushing the side surface of the head of the rail is turned by the distance adjusting rod 3 being turned. Since it changes, the position of the tongrel R2 with respect to the basic rail R1 in the branching device can be easily adjusted with high accuracy by pushing the side surface of the head of the rail. Therefore, by using the branching device tongue position adjusting tool 1, the position of the bolt hole for passing the bolt S22 that connects the retaining rod S2 and the connecting plate S21 can be easily adjusted.

  Since the distance adjusting rod 3 penetrates the pressing plate 2, the changeable range of the mutual distance d of the pressing plates 2 becomes larger than when the distance adjusting rod 3 does not penetrate.

  Each push plate 2 has a nut portion 23 projecting, thereby increasing the thickness of the portion and improving the strength of the female screw 21. Since the pressing plate 2 has a flat surface 222 opposite to the contact surface 221, the distance d between the pressing plates 2 can be reduced in the configuration in order to keep the Tongrel R 2 away from the basic rail R 1 (see FIG. 1). The branching unit tongue position adjusting tool 1 can be used even when the gap between the Tongleil R2 and the basic rail R1 is narrow.

  The turner tong position adjuster 1 performs an operation of moving the Tongrel R2 away from the basic rail R1 and an operation of bringing the Tongrel R2 closer to the basic rail R1 by reversing the direction of the push plate 2 with respect to the interval adjusting rod 3. This can be done with one unit. Moreover, the kind of parts which comprise the branching device tongue position adjustment tool 1 decreases, and manufacturing cost is reduced.

  Since it has the projection part 24 which protruded toward the abdominal part in the rail which the board part 22 pushes, it can prevent that the branching device tongue position adjustment tool 1 remove | deviates from a rail during use.

  In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, the distance d between the push plates 2a and 2b increases when the distance adjusting rod 3 is turned clockwise while the push plate 2b is viewed toward the front, and the push plate 2a when the distance adjustment rod 3 is turned counterclockwise. The branching device tongue position adjuster 1 may be configured and used so that the mutual distance d of 2b is reduced.
