Description

  The present invention relates to a switch adjuster, and more particularly to a switch adjuster having a wide application range.

  The switch adjuster is a device that transmits the power of the switching machine to the tongler of the branching unit, and plays a role of adjusting the difference between the movement of the switching machine and the stroke of the tongler. In other words, the switch adjuster is a device that converts the travel of the turning machine into a Tongleil stroke and attaches the Tongleil to the basic rail with a constant pressure.

  And the difference between the travel of the turning machine and the stroke of Tongleil differs depending on the combination of both, but is generally set to about 10 mm to 70 mm.

  Incidentally, the conventional switch adjuster shown in FIGS. 4, 5 and 6 is composed of the rod 5, the arm bracket 8, the cylinder nuts 6A and 6B, the nut 7 'and the like. Further, the conventional switch adjusters are divided into products using two types of cylinder nuts 6A and 6B having different lengths, and are used properly according to the difference based on the combination of the switch and the branching device. Reference numerals 91 and 92 are locking nuts for preventing loosening.

  For example, in the embodiment shown in FIGS. 4C and 5, the difference of 0 to 50 mm is obtained by using the cylindrical nut 6 </ b> A having a length of the lower neck portion (hereinafter sometimes referred to as the lower neck length) of 80 mm. It corresponds to. Moreover, in the Example shown in FIG.4 (d) and FIG. 6, it respond | corresponds to the difference of 30-80 mm by using the cylinder nut 6B whose neck length is 110 mm.

  On the other hand, in order to cover a wide range of differences with one type of product, there is a product in which both the width of the arm portion of the arm bracket and the length under the neck of the tube nut are long.

  Furthermore, for the purpose of provisional restoration, a switch adjuster including a rod adjusting mechanism that adjusts a rod length so as to be adapted to various branching devices is known from Patent Document 1, for example.

JP 2006-82624 A

  By the way, the conventional switch adjuster, which has been conventionally called "emergency" used for emergency countermeasures and called "universal type" that can be used for various types, has a horizontal width of the arm bracket and a neck of the cylinder nut. Longer dimensions are used.

  However, these conventional switch adjusters are designed on the premise that the set of devices constituting the branching device to be provided are used in a lump, and the use in combination with existing devices is completely considered. There is no current situation.

  On the other hand, emergency switch adjusters and the like are used in an emergency and need to be replaced as soon as possible. In the switch adjuster replacement / mounting operation, the arm bracket fixed with four bolts and nuts takes the longest time. Therefore, if there is no abnormality in the existing arm bracket, the working time can be greatly shortened if it is used as it is.

  However, with a conventional switch adjuster that uses a long nut under the neck, when the tube nut is inserted into an existing arm bracket in an emergency, the lateral width of the arm bracket is shorter than the neck length of the cylinder nut. Will not be able to adjust the difference between the tripping machine's travel and the Tongleil's travel.

  The present invention has been made in view of the above, and not only can be used even when there is no difference between the travel of the turning machine and the travel of the tongrel, but the existing arm bracket is used as it is. Even in such a case, an object is to provide a switch adjuster capable of adjusting the difference between the travel and the stroke.

  According to a first aspect of the present invention, there is provided a switch adjuster comprising: a rod connected to a rolling rod for converting a tongrel via an arm bracket; a cylinder nut and a special nut screwed into a male thread portion of the rod; The length of the cylindrical portion formed in the cylindrical nut is made longer than the width of the arm portion of the arm fitting through which the rod is inserted, and a part of the insertion hole opened in the special nut is expanded in diameter. A fitting portion having an inner diameter larger than the outer diameter of the tubular portion of the tubular nut is provided, and an internal thread portion is provided on the inner peripheral surface of the insertion hole, and the depth of the fitting portion is determined by the length of the tubular portion of the tubular nut and the It is set to be larger than the difference from the lateral width dimension of the arm portion, and a predetermined range on the distal end side of the cylindrical nut can be fitted into the fitting portion of the special nut.

  In the switch adjuster according to the present invention, no gap is provided between the cylinder nut or the special nut and the arm portion of the arm bracket, that is, from the state where the difference between the travel of the rolling machine and the stroke of the tongler is 0 mm, For example, up to a state with a large difference of about 80 mm can be handled with one switch adjuster, and the applicable range is extremely wide. For this reason, this switch adjuster can be used as a general-purpose product, and if this switch adjuster is used, quick recovery in an emergency becomes possible. Further, since this switch adjuster requires only one kind of member, inventory management, maintenance inspection, etc. are facilitated. Furthermore, since only one kind needs to be manufactured, the manufacturing process can be simplified. .

  The branching device 1 includes a point portion 11 that is converted by the electric switch 2, a crossing portion (not shown) that intersects the track, and a lead portion (not shown) that connects the point portion 11 and the crossing portion. Composed.

  The electric switch 2 is a device for converting and locking the point portion 11, moves in a predetermined stroke, and locks the point portion 11. And a locking lock 22 for the purpose. Inside the electric switch 2, the rotational force of the motor is transmitted to the operating can 21 via a friction clutch, a reduction gear, etc., and the operating can 21 is moved to change the point portion 11. In addition, the operation lock 21 and the lock lock 22 are locked so as to mechanically hold the positions.

  The point unit 11 is a tipping machine that divides the track and changes the course of the vehicle. The point portion 11 includes a tongrel T, a basic rail R, a floor plate, a rolling rod 31, a front rod 32, a connecting rod 33, a switch adjuster 4, and the like. In addition, when the direction of travel of the vehicle is the direction of arrow A, the point portion 11 has a direction in which the tongrel T is changed to the B direction and is always open, and the tongrel T is changed to the C direction. The state is upside down.

  The tongue rail T is a movable movable rail having a sharp front end. The front end portion of the Tongrel T is brought into close contact with the basic rail R and separated from the basic rail R by the electric switch 2. On the other hand, the rear end portion of the Tongrel T is fixed to a floor board or the like.

  The basic rail R is a rail with which the Tongrel T contacts. The floor board is a smooth iron plate that supports the Tongrel T movably. The rolling bar 31 is a member that drives the tongrel T at the time of conversion.

  The front rod 32 is a member that fixes the distance between the front end portions of the Tongle rail T, and maintains a close contact state between the Tongle rail T and the basic rail R so that the point portion 11 is not switched while the vehicle passes. . The connecting rod 33 is a member that connects the locking rod 22 and the front rod 32.

  The switch adjuster 4 is a device that sets the contact force when the Tongrel T comes into close contact with the basic rail R and sets the moving distance when the Tongrel T is changed. That is, the switch adjuster 4 connects the operation lever 21 and the rolling rod 31 by a rod described later, and by changing the force pushing the rolling rod 31 according to the fastening amount of the nut described later, Adjust the adhesion of the tongue rail T.

  And the switch adjuster 4 in this invention is equipped with the rod 5, the cylinder nut 6, the special nut 7, and the arm bracket 8 similarly to the conventional switch adjuster.

  The rod 5 constituting the switch adjuster 4 is a connection member connected to the operation lever 21. A male screw portion 51 is formed at the tip of the rod 5 (see FIG. 3). On the other hand, a connecting hole is formed at the rear end of the rod 5, and the connecting hole on the rod 5 side and the connecting hole on the operating can 21 side are connected by a joint pin that passes through these holes (see FIG. 1).

  Moreover, the cylinder nut 6 which comprises the switch adjuster 4 has the internal thread part 61 screwed together with the external thread part 51 of the rod 5, as shown to FIG. And a cylindrical portion 63 that protrudes from the nut portion 62 in a cylindrical shape and through which the male screw portion 51 of the rod 5 passes.

  Furthermore, the special nut 7 constituting the switch adjuster 4 is a nut for adjusting the adhesion. As shown in FIGS. 2D and 2E, the special nut 7 has a female threaded portion 71, and the male threaded portion 51 of the rod 5 is engaged with the female threaded portion 71 and attached to the rod 5 ( (See FIG. 3). A fitting portion 72 described later is formed in the female screw portion 71 of the special nut 7.

  The arm bracket 8 is a bracket-shaped bracket that is attached to and fixed to a rolling bar 31 that changes the Tonglerail T. The arm bracket 8 is integrally provided with an arm portion 81 formed in a cylindrical shape and a mounting portion 82 to which the falling rod 31 is attached. The arm portion 81 is a portion that guides the tube portion 63 of the tube nut 6 in a slidable manner and prevents rattling of the rod 5. That is, the cylindrical portion 63 of the cylindrical nut 6 is inserted into the inner peripheral portion 83 of the arm portion 81, and the male screw portion 51 of the rod 5 is further inserted into the cylindrical portion 63. Further, the lateral width of the arm portion 81 of the arm bracket 8 is set to the dimension B.

  On the other hand, four through holes 84 are formed in the attachment portion 82 of the arm bracket 8. Then, bolts are inserted into the through holes 84 and nuts are screwed into the bolts, so that the rolling bar 31 is fixed to the arm bracket 8.

  In the cylinder nut 6 according to the present invention, the length l of the cylinder portion 63, that is, the neck length l is set longer than the lateral width B of the arm portion 81 of the arm bracket 8. For example, the neck length l = 110 mm and the width dimension B = 80 mm. The special nut 7 according to the present invention is provided with a fitting portion 72. The fitting portion 72 has a part of the female screw portion 71 formed on the special nut 7 with an inner diameter D (for example, a diameter of 42 mm) slightly larger than the outer diameter d (for example, a diameter of 40 mm) of the cylindrical portion 63 of the cylindrical nut 6. The diameter is expanded so that In other words, it can be said that a part of the insertion hole 73 provided in the special nut 7 is enlarged in diameter to provide the fitting portion 72, and the female screw portion 71 is provided on the inner peripheral surface of the insertion hole 73. Further, the depth L of the fitting portion 72 is larger than the difference l−B between the length l of the tube portion 63 of the tube nut 6 and the lateral width dimension B of the arm portion 81 (l−B ≦ L). L is set to 35 mm.

  Therefore, when the cylindrical nut 6 is inserted into the arm portion 81 of the arm bracket 8, the predetermined range on the distal end side of the cylindrical portion 63 protruding from the arm portion 81 can be fitted into the fitting portion 72 of the special nut 7. For this reason, as shown to Fig.3 (a), it can mount | wear without providing a clearance gap between the cylinder nut 6 and the arm part 81, and between the special nut 7 and the arm part 81. FIG.

  3 (b) and 3 (c), the cylindrical nut 6 and the special nut 7 are attached to the rod 5 so that a gap of 20 mm is provided between the cylindrical nut 6 or the special nut 7 and the arm portion 81. It is screwed into the male threaded portion 51, and the locking nuts 91 and 92 are used to prevent loosening. Then, when the rod 5 is pulled, the inner end surface of the special nut 7 comes into contact with the opposite end surface of the arm portion 81, and between the end surface of the nut portion 62 of the cylindrical nut 6 and the other end surface of the arm portion 81. In this case, a gap of 20 mm is generated. At this time, a predetermined range on the distal end side of the cylindrical portion 63 of the cylindrical nut 6 is shallowly fitted into the fitting portion 72 of the special nut 7 (FIG. 3B).

  On the other hand, when the rod 5 is pushed, the end surface of the nut portion 62 of the cylindrical nut 6 abuts the opposite end surface of the arm portion 81, and the other end surface of the arm portion 81 and the inner end surface of the special nut 7 are in contact. Thus, a gap of 20 mm is generated. At this time, a predetermined range on the distal end side of the cylindrical portion 63 of the cylindrical nut 6 is shallowly fitted into the fitting portion 72 of the special nut 7 (FIG. 3C).

  Similarly, as shown in FIGS. 3D and 3E, the cylinder nut 6 and the special nut 7 are connected to the rod so that a gap of 80 mm is generated between the cylinder nut 6 or the special nut 7 and the arm portion 81. When the rod 5 is pulled, when the rod 5 is pulled, the end surface of the nut portion 62 of the tube nut 6 and the opposite end surface of the arm portion 81 are engaged with each other. A gap of 80 mm can be secured between them. At this time, the inner end surface of the special nut 7 abuts against the opposite end surface of the arm portion 81, and the tip portion of the tube portion 63 of the tube nut 6 is located on the inner peripheral portion 83 of the arm portion 81 of the arm bracket 8. (FIG. 3D).

  On the other hand, when the rod 5 is pushed, a gap of 80 mm can be secured between the other end surface of the arm portion 81 and the inner end surface facing the special nut 7. At this time, the end surface of the nut portion 62 of the tube nut 6 and the opposite end surface of the arm portion 81 come into contact with each other, and the distal end portion of the tube portion 63 of the tube nut 6 is positioned outside the arm portion 81 of the arm bracket 8. (FIG. 3E).

  Therefore, according to the switch adjuster 4 having the above-described configuration, when no gap is provided between the cylinder nut 6 or the special nut 7 and the arm portion 81 of the arm bracket 8, that is, the stroke of the rolling machine 2 One switch adjuster 4 can handle from the case where the difference between the stroke and the stroke of the Tongile T is 0 mm to the case where the difference is 80 mm.

  According to the switch adjuster according to the present invention, it is possible to deal with the difference between a wide range of travel and stroke, which cannot be handled by one type of member with the conventional switch adjuster, with one switch adjuster. . In other words, since the switch adjuster has a wide application range, it can be used as a general-purpose product, and if this is used, quick recovery in an emergency becomes possible. Moreover, since one kind of member is sufficient, inventory management, maintenance inspection, etc. become easy. Furthermore, since only one type needs to be manufactured during manufacturing, the manufacturing process can be simplified.

  Although the present invention has been described with respect to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and can be appropriately implemented without changing the configuration described in the claims. For example, the difference between the travel of the turning machine and the process of the tongrel, the dimensions of each part, and the like can be changed as appropriate.
