Description

  The present invention relates to a turning machine that performs conversion of a tongrel to a basic rail.

  Conventionally, there has been an index electric switch in the railway field (see Patent Document 1). The index electric switch is a conversion function that converts a pair of tongrels between a fixed position and an inverted position, a locking function that maintains the state of the tongrel at the end of conversion, and a non-opening path from the back side. The backward indexing function for securing the track of the vehicle has been realized.

  Specifically, the indexing electrical switch implements a conversion function using an operating rod for moving the Tongrel and a conversion roller for driving the operating rod. The lock function has been realized by using a lock rod for detecting the position of the end of the rail, a lock piece for locking the lock rod, and the like. Furthermore, in order to realize the backward indexing function, two of the above-mentioned operation hooks and lock hooks are provided so that they can be moved individually for each Tongrel.

  The conversion operation has been performed by the movement of the operation rod by the engagement between the conversion roller that moves in an arc shape and the cam surface that is formed in each of the operation rods. The entrance to the cam surface had a notch surface with a large relief width and a notch surface with a small relief width. A cut-out surface having a small relief width is formed at a portion that receives a driving force in the bonding direction from the conversion roller in the operation side of the Tongrel on the adhesion side, and the conversion roller in the operation side of the Tongleir on the opening side. A notch surface having a large relief width was formed in a portion that received a driving force in the opening direction from the top. As a result, in a state close to the conversion completion state, the conversion roller sufficiently comes into contact with the operation side of the adhesion side Tongrel, and the adhesion force can be reliably transmitted to the adhesion side Tongrel until the adhesion is completed.

In addition, during the conversion operation, the operation side of the bonding side Tongrel moves to the original conversion completion position, but the bonding side Tongrel itself may not be properly bonded to the basic rail due to the presence of foreign matter or the like. . In this case as well, the lock operation on the adhesive side Tongleil detects the non-contact state of the tip of the adhesive side Tongleil, and the conversion operation is properly completed when the lock piece has not reached the original locking position. I was able to detect that it was not.
Japanese Patent Laid-Open No. 7-96836

  However, in the above-described conventional indexing electric switch, two operating rods and two locking rods are provided, that is, four long members are provided, so that adjustment work during introduction and maintenance is complicated. Therefore, simplification was desired.

  In addition, the completion of the conversion operation and the lock were performed using the lock rod, but the completion of the conversion operation and the lock were performed without depending on the operation of the long member such as the lock rod. It is more preferable if possible.

  At present, particularly in the use of side lines for the purpose of vehicle replacement or detention, it is desired that the completion of the conversion operation and the locking can be reliably performed without using a locking rod.

  The present invention has been made in view of the above-mentioned circumstances, and can detect whether or not the tongrel is properly locked without using the lock paddle or without relying on the lock paddle. The purpose is to provide one machine.

  In order to solve the above-described problems, a turning machine according to the present invention drives a pair of operating rods that operate a pair of tonglers that can be switched between a normal position and an inverted position, and the pair of operating rods. A driving means for applying a driving force only to the operating rod on the side of the Tonglerail opening of the pair of operating rods at least in the vicinity of the localization or inversion; and at least in the vicinity of the tongue Elastic means for transmitting the driving force of the operation rod on the rail opening side to the operation rod on the Tongle rail adhesion side, and when the operation rod on the Tongle rail adhesion side has reached the end position corresponding to the localization or inversion And a locking means for locking the operating rod on the side of the Tongrel adhesion side, and a locking action detecting means for detecting completion or non-completion of the locking action in the locking means.

  Preferably, the driving means includes a conversion roller that moves in an arc shape, and the pair of operating rods each include a cam surface that engages with the conversion roller, and each of the cam surfaces has a relative position. The engagement securing surface having a small notch amount and the engagement avoiding surface having a large notch amount are included, and the engagement securing surface and the engagement avoiding surface are formed to face the operation direction of the operating rod. The pair of operating rods have an engagement securing surface on the opening operation front side of the Tongrel and an engagement avoidance surface on the bonding operation front side of the Tongrel.

  Further preferably, the switch of the present invention has an indexing function, and the elastic means is configured such that, during the indexing operation, only one of the pair of operating rods operates to The unlocking means is allowed to be unlocked, and after the unlocking, the moving force of the one operating rod is transmitted to the other operating rod.

  According to the present invention, the driving force is transmitted directly only to the operating rod on the Tongleil opening side in the vicinity of the orientation or the inverted position, and the operating rod on the Tongleil adhesion side is connected to the Tongleil opening side via the elastic member. Because the movement force of the movement rod is transmitted, the movement rod on the side of the Tongleil adhesion side can be stopped as it is when movement is restricted due to the presence of foreign matter, etc. It is possible to prevent movement to the end position. Therefore, the completion of the conversion operation and the lock can be properly detected without relying on the lock pad as in the prior art. Furthermore, the lock paddle can be omitted, which can contribute to simplification of maintenance and adjustment.

  Further, the elastic means allows only one operating rod to operate to unlock the locking means, and after unlocking, transmits the moving force of one operating rod to the other operating rod. When functioning, it is possible to detect the lock without relying on the lock pad as described above, and to secure the indexing function.

  The other features of the present invention and the operational effects thereof will be described in more detail with reference to the accompanying drawings.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment in which the switch according to the present invention is implemented as an index electric switch for side lines will be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. Further, the present invention is not limited to the side line.

  In FIG. 1, the turning machine 1 switches the Tongrel 7, 9 between the normal position and the inverted position with respect to the pair of basic rails 3, 5. The rolling machine 1 mainly includes a pair of operating rods 11 and 13, a driving unit 15, a coil spring 17 as an elastic unit, a locking unit 19, and a locking operation detection unit 21.

  The pair of operating rods 11 and 13 include arm portions 23 and 25 that extend in the direction of the interval between the basic rails 3 and 5 and the Tongrel 7 and 9, and main body portions 27 and 29 that receive the driving force from the driving means 15. . The main body portions 27 and 29 are provided on one end side of the arm portions 23 and 25, and the other ends of the arm portions 23 and 25 are connected to the corresponding tongrel 7 and 9 via the rods 31 and 33. .

  The driving means 15 includes a motor 35, a conversion gear 37, and a conversion roller 39 provided on the conversion gear 37 so as to be capable of rotating. A bevel gear 41 is attached to the output shaft of the motor 35, and a first intermediate gear 43 and a second intermediate gear 45 are arranged between the bevel gear 41 and the conversion gear 37 in a torque transmission relationship. The conversion roller 39 is attached to the conversion gear 37 so that the axis of the conversion roller 39 is at a position that is radially separated from the rotation center O of the conversion gear 37 by a predetermined distance. The conversion gear 37 is provided with a cam 47 that rotates concentrically with the rotation center O.

  The locking means 19 includes a pair of lock pieces 49 and 51. The lock pieces 49 and 51 are rod-like members extending in a direction substantially orthogonal to the operation direction T of the operation rods 11 and 13, and are arranged in a parallel relationship with each other. Further, the lock pieces 49 and 51 are provided so as to be slidable in the longitudinal direction, that is, in a direction substantially perpendicular to the operation direction T. Biasing means 53 and 55 made of a spring or the like are engaged with the lock pieces 49 and 51, and are always urged in a direction in contact with the main body portions 27 and 29 of the operating rods 11 and 13. Locking rollers 57 and 59 and cam follower rollers 61 and 63 are attached to the lock pieces 49 and 51, respectively, so that they can roll. The locking rollers 57 and 59 are provided to engage with the main body portions 27 and 29 of the operating rods 11 and 13, and the cam follower rollers 61 and 63 are provided to engage with the cam 47.

  The locking operation detection means 21 includes a swing piece 65, a swing amount adjusting member 67, and a circuit controller 69. The swing piece 65 is swingably supported on a base (not shown) of the switch 1 so that the swing center is located between the pair of lock pieces 49 and 51. In this embodiment, the swing amount adjusting member 67 is formed of a bolt member and is attached to each of the lock pieces 49 and 51. In each lock piece 49, 51, a pair of swing amount adjusting members 67 are arranged in a positional relationship so as to sandwich the corresponding end portion of the swing piece 65. The circuit controller 69 detects the completion or non-completion of the locking operation from the swinging state of the swinging piece 65 and outputs the information to the manager or the like.

  Next, the configuration relating to the driving force transmission from the conversion roller 39 to the operating rods 11 and 13 in the driving unit 15 will be described. First, cam surfaces 71 and 73 that engage with the conversion roller 39 are formed on the main body portions 27 and 29 of the operating rods 11 and 13. The cam surfaces 71 and 73 are formed as notches extending in a direction substantially orthogonal to the operation direction T of the operation rods 11 and 13 and opening toward the drive means 15 side. Further, an engagement securing surface 75 and an engagement avoiding surface 77 are formed on the opening side portion of the cam surface 71, and an engagement securing surface 79 and an engagement avoiding surface are formed on the opening side portion of the cam surface 73. 81 is formed.

  Both the engagement securing surfaces 75 and 79 and the engagement avoiding surfaces 77 and 81 are formed such that the side surfaces of the cam surfaces 71 and 73 are further cut away in the operation direction T of the operation rods 11 and 13. Further, the engagement ensuring surfaces 75 and 79 and the engagement avoiding surfaces 77 and 81 are arranged so as to face the operation direction T of the operation rods 11 and 13 on one cam surface 71 and 73. Further, the cutout amounts of the engagement avoiding surfaces 77 and 81 are larger than the cutout amounts of the engagement ensuring surfaces 75 and 79.

  The positional relationship between the engagement securing surface 75 and the engagement avoiding surface 77 in the operating rod 11 and the positional relationship between the engagement securing surface 79 and the engagement avoiding surface 81 in the operating rod 13 are the movement direction T of the operating rods 11 and 13. In relation to being reversed. That is, the engagement securing surfaces 75 and 79 are arranged on the front side during the opening operation of the later-described Tongleil in each operation rod, and the engagement avoiding surfaces 77 and 81 are described later in each operation rod. It is arranged on the front side during the bonding operation of the Tongrel.

  In the main body portions 27 and 29 of the operating rods 11 and 13, through holes 83 and 85 having substantially the same size in a rectangular shape in plan view are formed. The coil spring 17 is accommodated in the through holes 83 and 85 so that the winding axis thereof is substantially parallel to the operation direction T of the operation rods 11 and 13. A spring receiver is interposed between each end portion of the coil spring 17 and the defining portion of the through holes 83 and 85.

  FIG. 2 is a view showing an end of the main body of the operating rod on the side of the locking means. As shown in FIGS. 1 and 2, a locking surface 87 and an unlocking surface 89 are formed at the end of the main body 27 of the operating rod 11 on the side of the locking means 19. A locking surface 91 and an unlocking surface 93 are formed at the end of the main body 29 on the side of the locking means 19. The locking surfaces 87 and 91 and the unlocking surfaces 89 and 93 are formed so as to be directed in opposite directions to each other on both sides of the operation direction T of the main body portions 27 and 29 of one operation rod 11 and 13. The locking surfaces 87 and 91 are composed of surfaces substantially parallel to the sliding direction of the lock pieces 49 and 51. Further, the unlocking surfaces 89 and 93 are inclined with respect to the sliding direction of the lock pieces 49 and 51, and more specifically, approach the end surfaces 27 a and 29 a of the main body portions 27 and 29 on the lock piece 49 and 51 side. It is constituted by an inclined surface located closer to the center side of the main body portions 27 and 29.

  The positional relationship between the locking surface 87 and the unlocking surface 89 in the operating rod 11 and the positional relationship between the locking surface 91 and the unlocking surface 93 in the operating rod 13 are reversed with respect to the operating direction T of the operating rods 11 and 13. There is a relationship. That is, the unlocking surfaces 89 and 93 are arranged on the front side during the bonding operation of the tongrel described later in each operating rod, and the locking surfaces 87 and 91 are formed on the tongs described later in each operating rod. It is arranged on the front side during the opening operation of the rail.

  Next, the operation of the switch 1 having the above configuration will be described. First, in the present specification, the state as shown in FIG. 1 is described as a localization, but the present invention is not limited to this definition. In the state shown in FIG. 1, the tongrel 7 is open to the corresponding basic rail 3, and the tongrel 9 is bonded to the corresponding basic rail 5. Incidentally, in the stationary steady state, the conversion roller 39 is further rotated counterclockwise than in the state of FIG. 1 and is completely retracted from the cam surfaces 71 and 73. In addition, in order to ensure the clarity of the figure, the Tongleil 9 is illustrated as being slightly separated from the basic rail 5, but in actuality, it is assumed that both are in an adhesive state.

  The state of FIG. 1 is a state at the time when the conversion operation to the localization is properly completed, and the operation rods 11 and 13 each indicate a state where the terminal position corresponding to the localization is reached. Further, in this state, one lock piece 51 protrudes from the other lock piece 49 by the action of the urging means 55, and the locking roller 59 comes into contact with the locking surface 91 in the main body 29 of the operating rod 13. ing. As a result, the operation rod 13 on the side of the Tongrel attachment is prevented from moving in the direction of the opening of the Tongrel, that is, locked.

  Note that the operating rod on the side of the Tongrel adhesion indicates an operating rod that is bonded to the Tongrel at that time, or an operating rod that is operating in the direction of bonding to the Tongrel. On the other hand, the operating rod on the side of the Tonglerail opening indicates an operating rod that is open to the Tongrel at that time, or an operating rod that is operating in the direction in which the opening to the Tongrel is enlarged.

  The operation of unlocking and switching to the inverted position from the normal state of FIG. 1 will be described. First, the conversion gear 37 is rotated clockwise by the operation of the motor 35. As a result, the cam 47 rotates in the clockwise direction, and the conversion roller 39 also moves in the arc shape in the clockwise direction. In the cam 47, the lock roller 51 is locked by the protrusion of the lock piece 51 so far, so that the follower roller 63 is engaged with the small diameter portion 47a. However, when the cam 47 rotates in the clockwise direction, the large-diameter portion 47 b engages the follower roller 63, so that the lock piece 51 slides rightward in the drawing so as to align with the lock piece 49. As a result, the contact between the locking roller 59 and the locking surface 91 is canceled, that is, the locking means 19 is unlocked. As a result, the operating rods 11 and 13 are slidable.

  In parallel with the unlocking, the conversion roller 39 is engaged with both the cam surfaces 71 and 73 and rotates while proceeding to the deep part of the notch to transmit the driving force to the operating rods 11 and 13. To do. The driving force 13 on the Tongrel adhesion side and the operation rod 11 on the Tongleil opening side slide linearly and move toward the inverted position due to the driving force.

  When the operating rods 11 and 13 reach the end position corresponding to the normal position or the reverse position, the shift of the relative positions of the lock pieces 49 and 51 due to the lock is caused by the action of the swing amount adjusting member 67 and the swing piece 65. Appears as a predetermined inclination angle. Then, when the circuit controller 69 detects the inclined state of the swing piece 65, the completion of the locking operation in the locking means 19 is detected.

  On the other hand, when the vehicle travels from the back side in the non-opening path in the stationary steady state, an indexing operation is performed. First, when the vehicle enters from the back side, the open Tongrel 7 is urged toward the base rail 3 by the wheels. As a result, the operating rod 11 on the side of the Tongrel adhesion receives a downward driving force in the figure.

  Here, the locking means 19 has locked the operating rod 13 by the locking roller 59 coming into contact with the locking surface 91 of the operating rod 13, but the locking roller 59 does not move against the operating rod 11. Was only in contact with the unlocking surface 89. Therefore, the operating rod 11 can move downward in the figure while sliding the lock piece 51 to the right side in the figure by the slope of the unlocking surface 89. When the lock piece 51 is slid to some extent, the contact between the locking roller 59 and the locking surface 91 is canceled, that is, the locking means 19 is unlocked, and the operating rod 13 can move.

  Further, in the locked state by the locking means 19, only the operating rod 11 moves and the operating rod 13 cannot move, and therefore the coil spring 17 is compressed. Therefore, when the locking means 19 is unlocked as described above, the operating rod 13 also moves in the same direction as the operating rod 11 by the elastic force in the extending direction of the coil spring 17. Finally, the driving force from the driving means 15 is not used, and the tongler 7 is bonded to the basic rail 3 and the tongley 9 is opened from the basic rail 5 by the traveling force of the vehicle from the back direction. Thus, the indexing operation is completed.

  By the way, in the switching operation, the adhesion side Tongleil does not properly adhere to the basic rail due to the presence of foreign matter between the adhesion side Tongleil and the basic rail in the vicinity of the orientation or the inverted position. There is a case. In this case, in the conventional turning machine, the driving force of the conversion roller is transmitted to both the operation side on the Tongrel adhesion side and the opening side, or at least to the operation side on the Tongrel adhesion side. The operating rod on the tongue rail bonding side is deformed and moves to the end position corresponding to the normal position or the reverse position. When only the state of the lock piece is seen, the lock is performed and the intervening foreign matter is small. It seemed that the side Tongleil was properly bonded to the base rail.

  Therefore, in the present embodiment, such a phenomenon is prevented as follows. In the conversion operation to the normal position, the state in which the conversion roller 39 is returned by 90 degrees in the clockwise direction from the state of FIG. 1 will be described. The conversion roller 39 is engaged with both the operation rods 11 and 13 in the deep part of the cam surfaces 71 and 73. Match. From there, when the rotation of the conversion roller 39 proceeds in the counterclockwise direction, the engagement between the engagement securing surface 75 of the cam surface 71 and the conversion roller 39 is ensured in the operation rod 11 on the side of the Tongrel opening. On the other hand, in the operation rod 13 on the Tongleil adhesion side, since the cutout amount of the engagement avoiding surface 81 is relatively large, the conversion roller 39 is separated from the engagement avoiding surface 81. That is, the driving force of the driving means 15 is directly transmitted only to the operation rod 11 on the Tongleil opening side in the section near the localization.

  As described above, in the vicinity of the localization, the operating rod 11 on the Tongleil opening side is moved by the driving force directly transmitted from the driving means 15, and the operating rod 13 on the Tongleyl adhesion side is moved via the coil spring 17. The movement is caused by the moving force of the operating rod 11 on the side of the opening of the Tongrel opening, in other words, the elastic force of the coil spring 17. For this reason, when there is a foreign object or the like between the bonding side of the tongue rail 9 and the basic rail 5, only the movement rod 11 on the side of the tongrel opening moves further. When the coil spring 17 is compressed and absorbs the moving force to be transmitted from the operating rod 11 to the operating rod 13, the movement is stopped at a position where the movement is restricted by the foreign matter. Accordingly, it is possible to prevent the operation rod 13 on the side of the Tongrel adhesion side from moving to the end position corresponding to the localization and erroneously detecting the completion of the locking operation in the locking means 19.

  The same applies to the shifting operation from the normal position to the inverted position. In the vicinity of the inverted position, the driving force is transmitted only to the operating rod 13 on the Tongleil opening side via the engagement securing surface 79, and The moving force is transmitted through the coil spring 17 to the operating rod 11 on the side of the Tongleil adhesion side. Therefore, when the movement rod 11 on the Tongrel adhesion side is restricted from moving by a foreign object or the like, the coil spring 17 absorbs the moving force from the movement rod 13, and the movement rod 11 on the Tongrel adhesion side is restricted. Stop at position. Therefore, it can be prevented that the operation rod 11 on the Tongrel adhesion side moves to the end position corresponding to the inverted position and the locking operation completion in the locking means 19 is erroneously detected.

  As described above, according to the present embodiment, the driving force is transmitted directly only to the operation rod on the Tongleil opening side in the vicinity of the localization or the inverted position, and the elastic member is applied to the operation rod on the Tongleyl adhesion side. The movement force of the operating rod on the side of the Tonglerail opening is transmitted through the door, so that the moving rod on the Tongleil adhesion side can be stopped as it is when the movement is restricted due to the presence of foreign matter, etc. Therefore, it is possible to prevent the movement to the end position corresponding to the localization or the inverted position. Accordingly, it is possible to properly detect the completion of the conversion operation and the lock based on the operation of the lock means without relying on the lock pad as in the prior art.

  In addition, since it is possible to properly detect the completion of the conversion operation and the lock without relying on the lock paddle, as shown in this embodiment, the machine can be turned over without providing the lock padlock itself. Can be configured. For this reason, a long member and the structure accompanying it can be abbreviate | omitted, and it became possible to simplify the adjustment operation | work at the time of a fall machine introduction and a maintenance.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.

  First, in the above embodiment, the coil spring is employed as the elastic means, but the present invention is not limited to this, and other types of springs such as a leaf spring may be used. Furthermore, it is not limited to a metal spring, and may be an elastic force generating means made of resin, or an elastic force generating means using fluid pressure such as a pneumatic spring or a hydraulic spring.

  Further, the present invention does not necessarily require that the conversion roller is in contact with both of the cam surfaces of the pair of operating rods as in the embodiment in the operation section excluding the section near the normal position and the inverted position. Absent. Therefore, even in the operation section excluding the vicinity section, it may be in contact with only one cam surface of the operation rod. In other words, in the present invention, the driving force transmission mode can be appropriately changed in other operation sections as long as the driving force is directly transmitted only to the operation rod on the side of the Tonglerail opening at least in the vicinity section. It is.

  The driving means is not particularly limited as long as the operating rod can be driven linearly. Therefore, it may be a rotational driving force generation means other than a motor, or a linear driving force generation means. Therefore, the operation of the conversion roller is not limited to an arc shape, and may be a linear operation, for example.

  Furthermore, the present invention can also be applied to a turning machine equipped with a conventional lock paddle. Even in such a configuration, the lock can be detected without relying only on the operation of the long lock rod.

It is a figure which shows the structure of the switch machine which concerns on embodiment of this invention. It is a figure which shows the contact side edge part with the lock piece in an operating rod.
