Description

  The present invention relates to a conversion force correction device that is connected to a branching device laid in a section where a cant is attached to a track and corrects the conversion force that acts on the tongler of the branching device.

A conventional branching device is, for example, as shown in Patent Document 1.
In other words, the tongrel is disposed between the basic rails so that the position of the tongrel can be changed, and the direction of the train is changed by changing the position of the tongrel by the conversion force from the electric turning machine installed near the outside of the basic rail. Can be changed. Conventionally, such a branching device has been laid in a flat section where there is almost no difference in the height of the basic rail.

  By the way, when a train passes through a curved section where a track is drawn in a curve in a railway, a centrifugal force is applied to the train, and a force that attempts to overturn the vehicle to the outside of the curve is applied. Therefore, in the curved section of the roadbed, the height of the outside of the curve is made higher than the inside and the outer basic rail is made higher than the inner basic rail, thereby dispersing the force to overturn the vehicle and the curved section. The train can pass at high speed without overturning. This is said to be a cant on the railway.

  However, in recent years, along with the increase in the speed of trains, a cant is often added near the middle of a station. In addition, in the section where the distance between the stations is long, construction of a new station may be performed regardless of the curved section due to residents' requests. In these cases, there are many cases where a train that can pass at high speed is left in the operation of the train, and a train branched from there is laid to stop the train at the station. In this case, a branching device is installed at the branch point to change the train route by displacing the Tongleil between the stereotaxic position and the inverted position. The vessel inevitably becomes a canted state, so-called a canted branching device.

  However, the branching device is designed and manufactured on the assumption that it is laid on a flat place. Therefore, when installing the branching device, the crushed stone under the track is flattened and then laid. FIG. 9 shows the conversion force characteristics of the point portion having the movable portion of the branching device laid in this way. In FIG. 9, the vertical axis is the conversion force, and the horizontal axis is the stroke. As shown in the figure, the conversion force in the case of changing from the stereotaxy to the inversion and in the case of conversion from the inversion to the stereotaxy is theoretically the same magnitude as shown in FIG. It has the same conversion power characteristics.

  On the other hand, the conversion force characteristics of the point part of a branching device with a cant are, in theory, the conversion force increases when the tongrel is converted to the higher basic rail side by attaching a cant. When the Tongleil is converted to the lower basic rail side, the conversion force is reduced. The degree of increase and reduction of the conversion force becomes more prominent as the cant amount increases.

  However, the conversion force characteristic of a conventional switch for converting a branching device is designed to be used for a branching device without a cant. In other words, the conventional switch is suitable for switching a branching device having an unbalanced load. For this reason, a conventional switch is not suitable for switching a cantilever switch with a biased load.

  In addition, the conversion force characteristics of the point part of the branching device with a cant are the same conversion force characteristics as in the case of a branching device without a cant, but theoretically, when changing the tongue rail to the higher basic rail side When the Tongile is switched to the lower side of the basic rail, the conversion force is reduced, so the higher position of the basic rail in the area where the cant is large. It is difficult to convert the Tongrel to the side, and on the other hand, the conversion to the lower side of the basic rail will cause the Tongrel to slide down naturally under its own weight.

JP 2003-171903 A

  Therefore, when an existing turning machine is used to operate a cantilevered branching device, when converting the tongrel to the higher basic rail, the conversion force of the turning machine As the conversion force at the point approaches, the margin for conversion force decreases. As a result, in the case of a branching device without a cant, if the obstacle with a degree that does not interfere with the position change of the Tongile is a switching device with a cant, the conversion force of the point part is larger than the conversion force of the switch. As a result, the conversion becomes impossible and the train operation may be hindered.

  Conversely, when changing the position of the Tongrel to the lower basic rail side, the load on the tipping machine is lightened, but in extreme cases, the Tongrel is faster than the action of the tipping machine. There is a problem that the Tongrel collides with the basic rail and makes an abnormal noise or impacts the components of the turnout.

  In addition, the Tonglele slides on the inclined surface faster than the operation of the turning machine, which can cause problems such as making the movement of the operation can go wrong and making it impossible to convert, or causing uneven wear on the mechanism. There is a problem that can occur.

  The present invention has been made paying attention to such problems of the prior art, increasing or decreasing the conversion force of the branching device, making it difficult to make the conversion impossible, and occurrence of breakage due to the impact of the conversion It is an object of the present invention to provide a conversion force correcting device that can prevent a problem and install a branching device in a section where a track is attached.

The present invention operates as follows.
When the conversion force from the switch (200) is transmitted to the branching device (100) and the tongrel (T, T) is repositioned from the position to the inversion (or from the inversion to the position), the tongrel The conversion force correcting device (1, 1A) operates in conjunction with the conversion operation of (T, T) to add the correction force to the conversion force. Correcting force generating means connected to the Tongrel (T, T) side so as to be linked to the operation of the Tongrel (T, T) via the connecting means (20, 20A) of the conversion force correcting device (1, 1A). (10) accumulates corrective power in the corrective power source (12) in conjunction with the Tongrel (T, T), and releases the accumulated corrective power.

  This corrective force source (12) is, for example, a spring member (12), and when the tongrel (T, T) is shifted from a high position (or position) to a low position (or position). Is accumulated in the direction in which the spring member (12) is elastically deformed. In this direction change, the tongrel (T, T) slides down the slope, but the corrective force becomes a resistance force to correct the conversion force, so the tongrel (T, T) becomes the basic rail (R). , R), abnormal noise is generated, and components of the branching device (100) are prevented from receiving an impact.

  On the other hand, when the tongrel (T, T) shifts from a low position (or a reverse position) to a high position (or a position), the corrective force accumulated in the spring member (12) is When opened, it becomes an auxiliary force that assists in the conversion operation of the Tongrel (T, T) and corrects the conversion force. As described above, the correcting force can correct the characteristic of the conversion force due to the direction of the conversion operation of the Tongleil (T, T), and can make the characteristic of the conversion force almost symmetrical.

  In addition, it is preferable that the magnitude of the corrective power is such a size that the position of the tongrel (T, T) cannot be changed by itself, and more specifically, from the turning machine (200) to the tongrel The conversion force acting on the (T, T) side is preferably 0.5 times or less.

  The characteristic of the corrective force can be changed by changing the angle formed by the spring member crank (23) fixed to the crankshaft (22) and the tongler crank (24, 24A). For example, if the angle formed by the spring member crank (23) and the Tongler crank (24, 24A) is changed, the torque related to the spring member crank (23) and the Tongler crank (24, 24A) changes, so The characteristics can be changed.

  In addition, one end of the switch adjuster (105) is connected to the rolling rod (102) connecting the Tongrel (T, T), and the other end is connected to the tip end side of the Tongler crank (24). A connector (25) for connecting the switch adjuster (105) and the Tongler crank (24) is provided on the tip side of the Tongler crank (24) so that the fixing position can be changed. The corrective force can be changed by changing the fixing position of the connector (25).

  For example, if the connector (25) is fixed at a position near the base end of the tongrel crank (24), the distance from the fixed position to the crankshaft (22) is reduced, so that the corrective force can be increased. . Conversely, if the distance from the fixed position to the crankshaft (22) is increased, the corrective force can be reduced.

  According to the conversion force correcting device according to the present invention, the conversion force acting on the tongrel can be corrected, and the conversion force of the point portion of the branch device with a cant can be brought close to the conversion force in the case of a branch device without a cant. Therefore, when changing the direction of the Tongleil in either the low position or the high position, the conversion force characteristics can be made symmetric without causing a bias in the conversion force characteristics, so that There is room for it, and it can make it difficult for it to happen.

  As a result, when installing a turnout in a section with a cant on the track, the switchboard can be used without modifying or changing the conventional switchboard. There is no need to develop a new machine.

  Moreover, since the characteristic of the corrective force can be changed, it becomes even easier to use the conventional turning machine in the section where the track is attached to the can.

  In particular, when the tongrel is displaced to a low position, impact is applied to the components of the branching device and the rods connecting the switch and the branching device, but the spring member also serves as a buffer member. Since the impact is absorbed and reduced, damage to the components of the branching device and the turning machine can be prevented and their life can be extended.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 to 13 show a first embodiment of the present invention.
The conversion force correcting apparatus 1 according to the present embodiment is connected to a branching device 100 laid in a section where a track has a cant. The conversion force correcting device 1 performs a conversion operation of the tongrels T and T of the branching device 100 in a direction toward either the low localization position (or dislocation side) or the high disposition side (or localization side). Even at times, the output characteristics of the conversion force of the branching device 100 are corrected so as to be symmetric. In the following, for the sake of convenience, the localization of the tongrels T and T refers to the lower position, and the inversion refers to the higher position.

  As shown in FIG. 2, the section in which the conversion force correcting device 1 is laid is a section with a cant having a difference in height between the basic rails R and R by inclining the road bed 2. In FIG. 2, the tongrels T and T in the inverted position are illustrated.

  FIG. 1 is a plan view showing the connection relationship between the electric switch 200, the branching device 100, and the conversion force correcting device 1. The electric switch 200 is laid on the opposite side to the outside of the basic rails R and R. On the other hand, the conversion force correcting device 1 is laid near the outside of the basic rails R, R on the localization side. The tongrels T and T of the branching device 100 are provided between the basic rails R and R so that the position can be changed.

  In the branching device 100, the tongrels T, T are disposed between the basic rails R, R so as to be displaceable between a fixed position and an inverted position. Then, the traveling direction of the train can be changed by displacing the tongrels T, T between the localization and the inversion.

  The electric switch 200 includes an operation canister 201 and a lock canister 202 driven by an AC motor M. The operation canister 201 and the locking canister 202 are configured to be able to reciprocate in the respective axial directions.

  The operation canister 201 transmits the conversion force from the electric switch 200 to the branching device 100, and one end of the switch-side switch adjuster 101 is connected to the end closer to the branching device 100. ing. The switch adjuster 101 extends between the basic rails R and R through a gap between the basic rails R and R and the road bed 2.

  The other end of the switch-side switch adjuster 101 extending between the basic rails R and R is connected to a switch rod 102 fixed to the tongrels T and T. Thereby, the conversion force is transmitted by the electric switch 200 reciprocatingly moving the operating can 201, and the position of the tongrels T, T can be changed between the normal position and the reverse position. A conversion force correcting device-side switch adjuster 105, which will be described later, is also connected to the rod 102.

  The lock lock 202 detects the switching position of the Tongrels T and T that have been shifted to a normal position or an inverted position by the operation bar 201. The lock can 202 is connected to one end of the connection can 103 at the end close to the branching device 100. This connecting rod 103 also extends between the basic rails R, R through the gap between the basic rails R, R and the road bed 2. The other end of the connection rod 103 is connected to the substantially central portion of the front rod 104. The front rod 104 connects the tips of the tongrels T and T to each other.

  The conversion force correction apparatus 1 is connected to a correction force generation means 10 for generating a correction force for correcting the conversion force of the branching device 100 and the correction force generation means 10 in conjunction with the Tongler T and T sides of the branching device 100. And connecting means 20 for transmitting the corrective force to the Tongler T, T side.

  As shown in FIGS. 3 to 8, in the correcting force generating means 10, the spring seat 11 is fixed to the base plate P, and in the connecting means 20, the crank seat 21 is fixed on the base plate P.

  The corrective force generating means 10 includes a telescopic coil spring 12 as a corrective force source for generating a corrective force. The extension coil spring 12 is sandwiched between a spring seat-side spring receiver 13 and a crank-side spring receiver 14.

  The spring seat side spring seat 13 is pivotally attached to the spring seat 11. The crank-side spring receiver 14 is connected to a distal end portion of a spring member crank 23 whose base end portion is fixed to a crankshaft 22 rotatably provided on the crank seat 21.

  A spring receiving shaft 15 extends from the crank side spring receiver 14, and the spring receiving shaft 15 penetrates through the spring receiving seat side spring receiver 13, and a leading end thereof protrudes to the spring receiving seat 11 side. The spring bearing shaft 15 is not directly fixed to the spring seat-side spring receiver 13 itself, and a nut N is fixed to the tip portion. The expansion / contraction coil spring 12 is wound in a state where an initial pressure is applied to the spring bearing shaft 15, and is disposed substantially parallel to the basic rails R and R. Therefore, when the expansion coil spring 12 is compressed, the size of the tip of the spring bearing shaft 15 penetrating the spring seat side spring receiver 13 and coming out to the spring seat 11 side is increased. Conversely, when the expansion coil spring 12 is extended, the retracting of the distal end side of the spring receiving shaft 15 is limited until the nut N comes into contact with the spring seat-side spring receiver 13, and the expansion coil spring 12 extends beyond that. I can't do that.

  On the crankshaft 22, a Tongleyl crank 24, which is another crank, is fixed. The Tongleyl crank 24 has a proximal end fixed to the crankshaft 22 and a distal end connected to the Tongrel T and T sides.

  A connector 25 for connecting to the Tongrel T, T side is attached to the tip of the Tongrel crank 24. The connector 25 is axially coupled to the end of the conversion force correcting device side switch adjuster 105. The other end side of the conversion force correcting device side switch adjuster 105 is connected to the rolling rod 102 that connects the tongrels T, T.

  As shown in FIG. 7, the tip of the Tongleyl crank 24 and the connector 25 form a meshing portion 30 that meshes with each other. The connector 25 can be fixed by a bolt b and a nut n after meshing with the Tongrel crank 24 side at a desired position. As a result, the connector 25 can change the fixing position on the tip side on the Tongle rail crank 24 and can be firmly fixed so that the fixing position does not shift even when an external force is applied. it can.

  By changing the fixed position, the distance from the fixed position to the crankshaft 22 is changed, so that the torque due to the correcting force generated by the correcting force generating means 10 is changed, so that the magnitude of the correcting force can be changed.

  This corrective power is preferably large enough that the position of the Tongrel T and T cannot be changed by itself. Specifically, it is preferably 0.5 times or less of the conversion force acting on the Tongrel T, T side from the branching device 100.

  FIG. 10 illustrates the correction force characteristic of the conversion force correction apparatus 1 configured as described above. FIG. 11 shows the conversion force characteristic when the conversion force correction apparatus 1 having the characteristic indicated by the solid line among the correction characteristics illustrated in FIG. 10 is connected to the branch with a cant that shows the conversion force characteristic shown in FIG. Is shown. As shown in FIG. 11, the conversion force characteristic is corrected so as to be substantially symmetrical.

Next, the operation will be described.
The conversion force from the electric switch 200 is transmitted to the switch rod 102 through the switch-side switch adjuster 101 by the operation of the operation lever 201 by the electric switch 200, and the Tongler T, T Is repositioned between stereotaxic and inversion. At this time, the tongrels T, T and the conversion force correction device 1 are connected via the conversion force correction device side switch adjuster 105, and therefore the correction force is added to the conversion force from the conversion force correction device 1.

  The conversion force correction apparatus side switch adjuster 105 is connected to the connection means 20 of the conversion force correction apparatus 1, and the connection means 20 and the correction force generation means 10 operate in conjunction with the operations of the tongrels T and T. The corrective force generating means 10 accumulates the corrective force in the expansion coil spring 12 that is a spring member in conjunction with the Tongrel T, T, and releases the accumulated corrective force.

  When the tongue rails T and T are repositioned from a high position to a low position, the corrective force is accumulated by the deformation of the expansion coil spring 12 in the compressing direction. As seen in FIG. 1, the tongrels T, T are shifted in a direction toward the conversion force correcting device 1.

  As shown in FIG. 3, the position change in this direction is such that the tongler crank 24 of the conversion force correction device 1 connected to the conversion force correction device side switch adjuster 105 compresses the expansion / contraction coil spring 12 (arrow A direction). Rotate. When the tongue rail crank 24 rotates, the crankshaft 22 to which the tongrail crank 24 is fixed rotates. Then, with the rotation of the crankshaft 22, the spring member crank 23 fixed to the crankshaft 22 also rotates in the arrow A direction. As a result, as shown in FIG. 17, the crank side spring receiver 14 is moved in a direction approaching the spring seat side spring receiver 13, and the tip end side of the spring receiving shaft 15 fixed to the crank side spring receiver 14 is moved to the spring receiver. The extension coil spring 12 is compressed while protruding more from the seat side spring receiver 13 toward the spring receiver 11. 17 and 18 are explanatory diagrams of the second embodiment, but the operations of the corrective force generating means 10 and the connecting means 20 are the same as those of the corrective force generating means 10 and the connecting means 20 in the present embodiment. The operation is the same.

  When the position is changed in this direction, the tongrels T and T slide down the slope, but the tongrels T and T operate in a direction to compress the expansion coil spring 12, so that the correcting force of the conversion force correcting device 1 is correct. Becomes the resistance to the operation of Tongleil T, T and corrects the conversion power. As a result, the collision of the tongue rails T and T with the basic rails R and R can be absorbed and mitigated, so that abnormal noise is generated due to the collision and the components of the branching device 100 are damaged by the impact. Can be prevented.

  On the other hand, when the tongrels T, T are shifted from a low position to a high position, the corrective force accumulated by the compression of the expansion coil spring 12 is released. In FIG. 1, the tongrels T and T are repositioned in a direction approaching the branching device 100.

  As shown in FIG. 3, in the position change in this direction, the tongler crank 24 of the conversion force correction device 1 connected to the conversion force correction device side switch adjuster 105 extends the compressed extension coil spring 12 (arrow A). Rotate in the opposite direction). Then, with the rotation of the crankshaft 22, the spring member crank 23 fixed to the crankshaft 22 also rotates in the direction opposite to the arrow A direction. At the same time, as shown in FIG. 17, the compressed expansion / contraction coil spring 12 is extended by the restoring force, so that the crank side spring receiver 14 is pushed away from the spring seat side spring receiver 13 and the spring member crank 23 is moved. Rotation is assisted. The force for assisting the rotation of the spring member crank 23 is transmitted from the crankshaft 22 to the Tongleyl crank 24, and becomes an assisting force for rotating the Tongleyl crank 24 in the direction opposite to the arrow A direction.

  This auxiliary force is transmitted from the Tongler crank 24 to the rolling rod 102 via the conversion force correcting device-side switch adjuster 105, so that the Tongler T and T are shifted from the normal position to the inverted position. Become. Since this position change moves the tongrels T and T from a low position to a high position, the electric switch 200 requires a large conversion force, but the conversion force is assisted by the auxiliary force from the conversion force correction device 1. And corrected.

  As described above, the correction force from the conversion force correction device 1 corrects the deviation of the conversion force characteristic depending on the direction of the conversion operation of the Tongrel T and T, and makes the conversion force characteristic almost symmetrical. (See FIG. 11).

  The conversion power correction apparatus 1 can change the characteristic of the correction power. This change can be made by changing the fixing position of the connector 25 attached to the Tongler crank 24. For example, in order to increase the corrective force, the connector 25 may be fixed at a position near the base end of the Tongle rail crank 24 and the distance from the fixed position to the crankshaft 22 may be reduced. On the other hand, in order to reduce the corrective force, the connector 25 may be changed to a fixed position further away from the crankshaft 22 to increase the distance from the fixed position to the crankshaft 22.

  The electrical switch 200 and the conversion force correction device 1 are arranged so that the electrical switch 200 is laid on the opposite side of the basic rails R and R as shown in FIGS. In addition, the conversion force correcting device 1 may also be laid near the electric switch 200 on the same inversion side.

14 to 19 show a second embodiment of the present invention.
In the conversion force correction apparatus 1A according to the present embodiment, the connecting means 20A does not have the connector 25 in the connection means 20 in the conversion force correction apparatus 1 according to the first embodiment. The engagement portion 30 in which the connector and the connector 25 are engaged with each other is not formed, and the end of the conversion force correcting device side switch adjuster 105 is directly connected to the tip of the Tongler crank 24A by the connecting shaft 40. Are different.
In addition, arrangement | positioning of the electric tipper 200 and the conversion force correction apparatus 1A is the same as what was shown in FIG. 12 and FIG. 13 in 1st Embodiment. Further, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

Next, the operation will be described.
The action of the conversion force correction apparatus 1A is the same as that of the conversion force correction apparatus 1 according to the first embodiment, but since the connecting means 20A does not have the connector 25, the characteristic of the correction force can be changed. The way is different.

  In the conversion force correcting device 1A, in order to change the characteristic of the correcting force, the angle formed by the spring member crank 23 of the connecting means 20A and the Tongleyl crank 24A may be changed. As a result of this change, the torque related to the spring member crank 23 and the Tongleyl crank 24A changes, so that the corrective force characteristics change.

  As described above, according to the conversion force correcting devices 1 and 1A, the conversion force of the branching device 100 is corrected, and the conversion force of the point portion of the branching device 100 with the cant is changed to the conversion force in the case of the branching device without the cant. You can get closer. As a result, when the Tongrel T, T is repositioned between the localization and the inversion, the conversion force characteristics can be made symmetric without causing any bias regardless of the direction of the relocation. As a result, there is a margin in the conversion power, which makes it difficult for the conversion to occur.

  In addition, when installing a turnout in a section where a track is attached to a canal, a conventional switch can be used as it is without modification or change.

  Furthermore, especially when the tongrel is displaced to a low position, impact is applied to the components of the branching device and the rods connecting the switch and the branching device, but the expansion / contraction coil spring also serves as a buffer member.
