Description

The present invention relates to a rail direct connection device for connecting a rail in a railroad turnout and a turning machine for converting the rail, and a floor plate for the turning machine.

In a rail direct connection device, for example, as illustrated in Non-Patent Document 1, it is common to fix a floor plate on which a rolling machine is placed to a sleeper with a claw bolt. In this case, a hole is made in the sleeper to attach the floor board with the claw bolt. Non-Patent Document 1 describes that a hole is provided in the sleeper so as to be aligned with the center of the hole in the elliptical portion provided in advance on the floor plate. It should be noted that the holes in the elliptical portion or the holes in the oval portion provided in advance on the floor plate have a long shape in the direction orthogonal to the extending direction of the rail, so that there is some margin in this direction. It is in a state. On the other hand, the extension direction of the rail has a structure that does not allow a margin for alignment and the like.

However, when it is necessary to adjust the relative position between the rolling machine and the target rail of the rolling machine due to various factors such as the load applied to the rail over time after installing the rolling machine. There is. On the other hand, in the case of mounting by a general method as in the above example, sufficient adjustment is not always possible, and for position adjustment, for example, re-drilling a hole provided in the sleeper is performed. Large-scale work was required.

It makes it possible to change the layout of the tumbling machine. As a result, the rail direct connection device can quickly and easily adjust the position between the rolling machine and the rail without the need for re-drilling holes provided in the sleepers, for example.

In a specific aspect of the invention, the plate has a plurality of patterns for the location of the holes. In this case, the position can be adjusted by selecting from a plurality of patterns.

It is a conceptual plan view for demonstrating one modification about a plate.

Hereinafter, the rail direct connection device and the floor plate for the rolling machine according to the present embodiment will be described with reference to FIG. 1 and the like. In the following, as an example, as shown in the figure, the extending direction of the basic rail SR, that is, the laying direction is the Y direction, and the directions orthogonal to each other in the plane perpendicular to the Y direction are the X direction and the Z direction. .. Of these, the left-right direction orthogonal to the Y direction in the horizontal plane including the Y direction in which the basic rail SR is laid is defined as the X direction, and the vertical direction perpendicular to the X direction and the Y direction is defined as the Z direction. Further, the X direction is defined as the first direction D1, and the Y direction is defined as the second direction D2. That is, here, the extending direction of the basic rail SR is the second direction D2.

As illustrated in FIG. 1, the rail direct connection device 10 of the present embodiment is a device for mounting and fixing the roll machine 20 in the turnout P, and is a floor plate 11 for the roll machine. , Four mounting mechanisms 12 for fixing the floor plate 11 to the sleeper SP of the railroad track, four fixing devices 13 for mounting and fixing the turnout machine 20, and a pair for fixing to the basic rail SR. It is provided with gauge ties 14a and 14b.

The floor plate 11 which is a floor plate for a rolling machine is an iron-made rectangular plate-shaped member, and supports the main body portion 20a, which is the main part of the rolling machine 20, by mounting it on the central mounting portion PS. At the same time, in the mounting portion MS provided on the peripheral side of the mounting portion PS, the main body portion 20a is fixed at the predetermined positions at the four corners by providing the four fixing devices 13. Further, the floor plate 11 is placed on one end of the first sleeper SP1 and the second sleeper SP2, which are longer than the normal sleepers SP arranged at predetermined intervals, so that the floor board 11 is lateral to the turnout P of the railroad track. Further, it is fixed to the first sleepers SP1 and SP2 so as not to move by the mounting mechanism 12 provided in the mounting portion MS.

As described above, the mounting mechanism 12 is a mechanism for fixing the floor plate 11 to the first sleepers SP1 and SP2, and is a mechanism for fixing the main body portion 20a of the mounting portion MS which is a peripheral portion of the floor plate 11. It is provided on the peripheral side of the two fixing devices 13. In the mounting mechanisms 12 provided at the four corners of the floor tie 11, the floor tie 11 is fixed by a claw bolt CB (see FIG. 2B), which is a bolt that penetrates and fastens the sleeper SP, and eventually rolls. The machine 20 is fixed to the first sleepers SP1 and SP2. The structure of the mounting mechanism 12 will be described in detail with reference to FIG. 2 and the like.

The fixing device 13 is composed of, for example, mounting brackets, a plurality of bolts, nuts, etc. (see FIGS. 1 and 2 (A) to 2 (C)), and is a rolling machine 20 mounted in the center of the floor plate 11. The main body portion 20a of the above is supported and fixed so as not to move with respect to the floor plate 11. For this reason, in the illustrated example, fixing devices 13 having the same shape are provided at the four corners of the main body 20a, and are fastened at each of the four corners of the main body 20a. I try not to change. By being fixed by the fixing device 13, for example, even if the floor plate 11 is moved while the main body portion 20a is placed on the floor plate 11, the arrangement relationship between the floor plate 11 and the main body portion 20a is maintained.

The pair of gauge ties 14a and 14b are rod-shaped members, one end of which is attached to the floor plate 11 by a joint metal fitting JB, and the other end of which is attached to the basic rail SR by a fastener TG. That is, the pair of gauge ties 14a and 14b mount and fix the floor plate 11 to the basic rail SR.

Next, the outline of the structure of the rolling machine 20 and the like will be described. The turnout machine 20 is an electric turnout machine, and among the basic rail SR and the tongue rail TR on the sleeper SP constituting the turnout P, the tongue rail TR is moved to move the train in the turnout P. The course is being switched.

Here, as illustrated in the figure, in order to perform the above-mentioned switching operation, the tumbling machine 20 has an operation can extend from the inside of the main body 20a, for example, in addition to the main body 20a provided with a motor or the like as a power source. It is provided with a switch adjuster rod 21 connected to, a lock can 22 and the like. The main body 20a has a motor, a power device for moving the motor, and the like, and moves the operation can forward and backward to generate a conversion force when moving the tongue rail TR. The switch adjuster rod 21 is connected to a tie bar TB provided on the tongue rail TR, and transmits an operation from the main body 20a to the tongue rail TR. The lock can 22 is a member for fixing the position after the switching operation, and after the switching operation by the turnout machine 20, the switch adjuster rod 21 or the operation can connected to the switch adjuster rod 21 is chained at the localization position and the reverse position, respectively. Lock.

It is very important to support and fix the tumbling machine 20 at a predetermined position in the rail direct connection device 10 having the above structure or the laying plate 11 which is the laying board for the tumbling machine, as described above. This is made possible by the configuration. After installing the turnout machine 20, due to various factors such as the load applied to the tongue rail TR with the passage of time, the relative positional relationship of the turnout P including the turnout machine 20 and various members around it shifts. May require position adjustment. However, it is possible that the adjustment for the second direction D2 has not been fully considered so far. On the other hand, in the present embodiment, the mounting mechanism 12 also functions as a mechanism for adjusting the position, and in particular, the position adjustment is performed not only for the first direction D1 but also for the second direction D2. It is possible.

Hereinafter, an example of the structure of the rail direct connection device 10 centered on the mounting mechanism 12 will be described with reference to FIG. 2 and the like.

FIG. 2A is a plan view for explaining an example of the mounting mechanism 12 which is a structure for mounting and fixing the floor plate 11 to the sleepers SP1 and SP2 among the rail direct connection devices 10, and is a broken line XX in FIG. It is an enlarged view about the part shown by the circle. That is, it is a plan view which showed one of the four mounting mechanisms 12 provided in the mounting part MS of the floor plate 11. Since the remaining three mounting mechanisms 12 are the same, the description and the like will be omitted. 2 (B) and 2 (C) are cross-sectional views corresponding to FIG. 2 (A), and FIG. 2 (B) is viewed from the direction shown in AA in FIG. 2 (A). Corresponds to the figure. Further, FIG. 2C corresponds to a view seen from the direction shown in FIG. 2B in FIG. 2A.

As shown in FIGS. 2 (A) to 2 (C), the mounting mechanism 12 is a metal plate PL having a square cylinder-shaped square collar SC and a metal rectangular flat plate member having an insertion hole HL. And a cylindrical insulating color IC made of an insulating material. First, in the mounting mechanism 12, the square collar SC is housed in the rectangular through hole HH for passing the claw bolt CB provided in the mounting portion MS of the floor plate 11, and the plate PL is placed on the square collar SC. Further, the insulating color IC is housed in the insertion hole HL provided in the plate PL. By tightening the nut NT with the claw bolt CB penetrating through the insulating collar IC, the floor plate 11 is sandwiched and fastened between the mounting mechanism 12 and the sleeper SP1. That is, the position of the claw bolt CB, which is a bolt to be fastened to the sleeper SP1, is a fixed position where the floor plate 11 extends and the rolling machine 20 is attached to the sleeper SP1. Regarding the assembly of the claw bolt CB, it is necessary to make a hole in the sleeper SP1 and further hook the claw portion of the claw bolt CB to the bottom of the sleeper SP1. It should be noted that this structure is the same in other mounting mechanisms 12 for which description is omitted.

Hereinafter, each part of the mounting mechanism 12 having the above-described configuration will be described in more detail. 2 (D) is a plan view and a cross-sectional view showing the structure of the square color SC extracted from FIGS. 2 (A) to 2 (C), and FIG. 2 (E) is FIG. 2 (A). ) To the cross-sectional view showing the structure of the plate extracted from FIGS. 2 (C), and FIG. 2 (F) shows the structure of the insulating color IC extracted from FIGS. 2 (A) to 2 (C). It is a plan view and a cross-sectional view which show.

First, the square collar SC is a square tubular metal member with a shoulder, and as shown in FIGS. 2 (A) to 2 (C) and 2 (D), the rectangular through hole of the floor plate 11 In the state of being housed in the HH, there is some clearance CR in the X direction, that is, the first direction D1, while in the Y direction, that is, the second direction D2, there is almost no clearance on the floor plate 11 at the shoulder portion. It is designed to be in close contact. That is, in the square color SC, the first direction D1 is allowed to move to some extent in the loosely fitted state, while the second direction D2 is in a state where there is no play and the movement does not move.

Further, as shown in FIG. 2D, the square color SC has a shape in which the receiving side of the plate PL matches the size and shape of the plate PL on the inner surface of the square cylinder for accommodating the plate PL. , The plate PL fits in the relevant place with substantially no clearance, and has a stepped portion in the intermediate portion, and the size of the hole at the tip thereof is smaller than that of the plate PL, and the plate PL is the same. It is designed not to go deeper than that. As a result, as shown in FIG. 2B or FIG. 2C, the plate PL is positioned and fixed at the stepped portion of the square collar SC.

Next, as shown in FIG. 2 (E), the plate PL is a rectangular open metal member having rounded corners, and as described above, the square collar SC has substantially no clearance. It is designed to fit in. Further, a part of the flat surface portion is provided with an insertion hole HL which is a round hole for passing the claw bolt CB. The insertion hole HL has a size and shape in consideration of the diameter of the claw bolt CB and the thickness of the insulating color IC. In the present embodiment, a plurality of plates having different hole positions are prepared, and one of the plates is appropriately selected (see, for example, FIG. 5). That is, the plate PL can be replaced. This point will be described in detail later.

Finally, as shown in FIG. 2 (F), the insulating collar IC is a cylindrical insulating member with a shoulder, and is brought into close contact with the plate PL at the shouldered portion with substantially no clearance. It fits in the insertion hole HL of PL. As shown in FIG. 2B or FIG. 2C, a round hole through which the claw bolt CB passes without a gap is provided in the center of the insulating collar IC.

Here, in the present embodiment, as the plate PL, a plurality of plates having different hole positions are prepared (in the example of FIG. 5, three plates PLa, PLb, each having an insertion hole HL at a predetermined position). PLc is available). As a result, by exchanging the plate PL according to the installation condition of the turnout P (see FIG. 1), appropriate position adjustment, particularly position adjustment in the second direction D2 is possible.

Hereinafter, an example of a method of adjusting the position of the turning machine 20 in the second direction D2 by exchanging the plate PL will be described with reference to FIG. 3 and the like.

First, FIG. 3A is a plan view and a cross-sectional view showing an example of the state of mounting and fixing in the initial state (state S1) of the installation of the rolling machine 20. Since this figure is the same as the case shown in FIGS. 2 (A), 2 (C), and 2 (E), the description thereof will be omitted. On the other hand, FIG. 3B shows an example of mounting and fixing in the state (state S2) after the position of the rolling machine 20 has been adjusted after a lapse of time from the initial state (state S1). It is a plan view and a cross-sectional view which show. That is, FIG. 3 (B) shows a state in which the plate PL is replaced with one having a different hole position in order to adjust the position with the passage of time from the state at the time of initial installation shown in FIG. 3 (A). Is shown. More specifically, with respect to the insertion hole HL, which is a hole provided in the plate PL, in the initial state S1 shown in FIG. 3A, the one located at the center position in the longitudinal direction LL corresponding to the second direction D2 is used. It is adopted. On the other hand, in FIG. 3B, the one located at a position shifted downward from the center in the longitudinal direction LL is adopted. FIG. 4 compares the positions of the second direction D2 with respect to the difference between the initial state S1 shown in FIG. 3 (A) and the state S2 after the position adjustment shown in FIG. 3 (B) with reference to the position of the claw bolt CB. It is a thing. In this case, the position of the floor plate 11 of the rail direct connection device 10 and the position of the rolling machine 20 are set to the position of the insertion hole HL of the plate PL with respect to the position of the claw bolt CB. It means that the direction D2 can be moved to the upward side (+ Y side) of the paper surface indicated by the arrow A1. That is, the machine 20 that rolls in this direction by changing the position of the hole through which the claw bolt CB is inserted along the second direction D2, which is the extending direction of the rail, without changing the position of the claw bolt CB with respect to the sleeper SP1. Since the position of the can be moved, it is not necessary to re-drill the hole for the claw bolt CB when adjusting the position. As a result, the burden of adjusting the position of the rolling machine 20 can be significantly reduced.

Hereinafter, an example will be shown with reference to FIG. 5 regarding the selection of the plate PL. As illustrated in FIG. 5, here, three plates PLa, PLb, and PLc having different hole positions are prepared, assuming that the insertion holes HL are provided at predetermined positions. That is, depending on the situation, one plate is selected from these plates PLa, PLb, PLc and used as a plate PL, that is, by making it replaceable with one plate, a plurality of patterns for the position of holes can be obtained. I am trying to have it. In the example of FIG. 3, regarding the rectangular longitudinal direction LL corresponding to the second direction D2 at the time of installation, the first plate PLa having the insertion hole HL at the center position and the position slightly deviated from the center position in the longitudinal direction LL. A second plate PLb having an insertion hole HL and a third plate PLc having an insertion hole HL at a position further deviated from the second plate PLa in the longitudinal direction LL are prepared. Various modes are possible for the degree of deviation of the position of the insertion hole HL as described above. For example, the difference in position between the first plate PLa and the second plate PLb in the longitudinal direction DH1 is 5 mm. It is conceivable that the difference in position DH2 between the second plate PLb and the third plate PLc in the longitudinal direction LL is 5 mm.

As for the usage mode of the plate PL, for example, when the first rolling machine 20 is installed, the first plate PLa is adopted, and depending on the need for position adjustment, the second plate PLb or the third plate PLc is used. It is expected that the product will be replaced.

Further, in the above description, only one of the four mounting mechanisms 12 illustrated in FIG. 1 has been described, but when adjusting the position of the tumbling machine 20 once, normally, the four mounting mechanisms 12 are used. The same replacement will be done for all at the same time.

Hereinafter, an example will be described in which the position adjustment of the rolling machine 20 is required with reference to FIG. Various cases are assumed as factors that require position adjustment, but as a typical example, interference between the switch adjuster rod 21 and the tie bar TB with aging can be considered. As shown in FIG. 6A, for example, at the start of installation, a sufficient clearance CC is provided between the switch adjuster rod 21 and the tie bar TB, as shown by being surrounded by the broken line YY. Although they are in substantially the same position in the height direction, that is, in the Z direction, they do not interfere with each other. However, the tongue rail TR may move in the extending direction of the rail, that is, in the second direction D2 due to the action of repeated train passages and the like. For example, if the tongue rail TR continues to be affected by the action of moving in the direction of arrow A2 (direction of −Y), as shown in FIG. 6 (B), the tie bar TB moves with the action of the tong rail TR, and eventually the tie bar TB is moved. The clearance CC between the switch adjuster rod 21 and the tie bar TB may be narrowed. On the other hand, in the present embodiment, by replacing the plate PL as described above, the required amount of the turning machine 20 can be easily and surely moved, that is, the position can be adjusted. In addition, as the cause of the phenomenon as shown in FIG. 6, the matter acting on the tongue rail TR has been illustrated above, but the above-mentioned deviation may occur due to various other factors. Further, in the above, the second direction D2 can move in either a positive direction or a negative direction depending on the usage environment.

In addition, at the time of the position adjustment as described above, the rolling machine 20 and the other members constituting the rail direct connection device can be adjusted separately, and after the position adjustment by replacing the plate PL, each part Is adjusted separately. For example, the pair of gauge ties 14a and 14b are appropriately readjusted by the joint metal fitting JB and the clamp TG as necessary.

7 (A) to 7 (E) are views for explaining a floor plate for a tumbling machine and a rail direct connection device of a comparative example. 7 (A) to 7 (D) correspond to FIGS. 2 (A) to 2 (D), and FIG. 7 (E) corresponds to FIG. 2 (F). That is, the rail direct connection device of this comparative example is different from the rail direct connection device 10 of the present embodiment described above in that the plate PL illustrated in FIG. 2 (E) and the like is not provided in the present embodiment. There is. Further, in this comparative example, the through hole HH provided in the mounting portion MS of the floor plate 11 is not rectangular but oval with the first direction D1 as the longitudinal direction, and the collar SCa housed in the through hole HH is also cylindrical. It is not a square shape, that is, a square cylinder shape. In this case as well, the cylindrical collar SCa has some clearance CR in the X direction, that is, the first direction D1, while being housed in the through hole HH, while it has almost no clearance CR in the Y direction, that is, the second direction D2. In the state where there is no clearance, the portion with the shoulder is in close contact with the floor plate 11. In this case, in the first direction D1, which is the direction in which a large force is applied in the rail conversion operation by the rolling machine 20, a certain amount of play is provided to suppress damage or deterioration of the fixed portion, and the rail conversion operation. In the second direction D2, which is considered not to apply a relatively large force, misalignment is unlikely to occur. However, in the case of this comparative example, it is not always possible to deal with the adjustment of the misalignment in the second direction D2 with aging as illustrated in FIG. 6 with respect to the rail direct connection device 10 of the present embodiment by a simple method. In such a case, in order to adjust the position of the rolling machine 20, for example, a large-scale work such as re-drilling the holes for the claw bolts CB provided in the sleepers SP1 and SP2 is required.

On the other hand, in the present embodiment, with respect to the first direction D1, a relatively large force is applied while corresponding to the force applied during the rail conversion operation in the state of being loosely fitted in the square collar SC. With respect to the second direction D2, which is not provided, the square collar SC and the plate PL are set so that there is almost no clearance so that misalignment is unlikely to occur. Further, regarding the misalignment of the second direction D2 due to aging, by making the plate PL replaceable, the position of the rolling machine 20 can be adjusted by a simple method without the need to replace the claw bolt CB. Is possible.

FIG. 8 is a conceptual diagram for explaining the difference in the mounting / fixing structure between the above-described embodiment and the one modification shown in FIG. 7. 8 (A) and 8 (B) are conceptual diagrams showing the mounting and fixing structure in the present embodiment, and FIG. 8 (C) shows the mounting and fixing structure in one comparative example shown in FIG. 7. It is a conceptual diagram.

As shown in FIG. 8A, in the present embodiment, the width W2 of the through hole HH is slightly wider than the width W1 of the square color SC hatched in the figure in the first direction D1. This allows the square collar SC to move in the first direction D1. On the other hand, the second direction D2 is not provided with a difference that allows the square color SC to move. Further, if the plate PL is not replaced, it does not function as a moving element in the second direction D2. However, as shown in FIG. 8B, the position of the insertion hole HL, that is, the position of the hole through which the claw bolt CB is penetrated can be changed by exchanging the plate PL provided inside the square collar SC. From a different point of view, the positions of the floor plate 11 and the rolling machine 20 can be changed without changing the position of the claw bolt CB. That is, it is possible to adjust the position of the rolling machine 20 with respect to the positional deviation in the second direction D2. Further, in other words, the square collar SC changes the fastening position of the claw bolt CB in the first direction D1 for the floor plate 11 or the rolling machine 20, and the plate PL intersects the first direction D1. It means that the fastening position of the claw bolt CB is changed in the second direction D2.

On the other hand, in the modified example shown in FIG. 7, as shown in FIG. 8C, the width W2 of the oval through hole HH is the width W1 of the cylindrical collar SCa in the first direction D1. The structure is such that the square color SC is allowed to move by being slightly wider than the above, while the second direction D2 is not provided with a difference that allows the square color SC to move. However, unlike the present embodiment, it does not have a structure for adjusting the misalignment in the second direction D2.

Hereinafter, as a modification of the plate PL with reference to FIG. 9, an example will be described in which the position of the hole through which the claw bolt BC is inserted is changed by changing the orientation in which the plate PL is installed. The plate PL of this modification is the same as shown in the figure, and the position of the insertion hole HL is not in the center in the longitudinal direction LL. By setting the plate PL in the opposite direction, the insertion hole HL can be formed. The position has been changed. For example, when adjusting the position so that the second direction D2 can be moved in either the positive direction or the negative direction depending on the usage environment, the plate PL is used by turning it upside down depending on the situation as described above. Can be considered. In this case, by utilizing the symmetry of the rectangular shape of the plate PL, the plate PL can be fitted into the square color SC with almost no gap, that is, the clearance without changing the square color SC. It is possible to maintain a state in which it does not occur.

As described above, the rail direct connection device 10 according to the present embodiment rolls the plate PL having the insertion hole HL, which is a hole for inserting the claw bolt CB, which is a bolt to be fastened to the sleepers SP1 and SP2, at a predetermined position. By replaceably attaching the tie machine 20 to the floor plate 11 on which the tie machine 20 is placed, it is possible to change the arrangement of the tumbling machine 20 by exchanging the plate PL. As a result, in the rail direct connection device 10, for example, it is not necessary to re-drill the holes for the claw bolts CB provided in the sleepers SP1 and SP2, and the rolling machine 20 and the rail can be quickly and easily connected to each other. The position can be adjusted.

The present invention is not limited to the above-described embodiment, and can be implemented in various embodiments without departing from the gist thereof.

First, in the above, a plurality of plates having holes at different positions are prepared, but various modes are possible for the plates whose hole positions can be changed, and one as in the above modification. The position can also be changed by changing the orientation of the plate. It is also conceivable that one plate can be changed to a plurality of positions.

Further, the difference in the position of the hole in the plate PL is set to every 5 mm in the above, but the difference is not limited to this, and various types can be prepared depending on the required accuracy, the amount of movement, and the like. Further, various shapes of the plate PL can be considered.
