Description

  The present invention relates to an adhesion degree measuring device that measures the degree of adhesion of a tongrel in a railway branching device in close contact with a basic rail.

  In a railway, a plurality of tracks are laid, and a branching device is provided to move the vehicle from one track to another. As shown in FIG. 7, the branching device 2 has fixed basic rails 23 and 24 and converted tonglers 21 and 22. When the vehicle passes, either one of the left and right basic rails is used. 23 is closely attached with the Tongrel 21. The state in which the tongue rail 21 is in contact with the basic rail 23 with a certain pressure is referred to as the close contact of the tongue rail 21 (see JIS E 3013). The degree of strength at which the tongue rail 21 is in close contact with the basic rail 23 is referred to as the degree of adhesion. The degree of adhesion is determined by applying an external force from the state where the Tongrel 21 is in close contact with the basic rail 23 to create a gap (opening) between the tip of the Tongrel 21 and the basic rail 23, and the gap amount S (opening amount). Is measured as a pressing force by the Tongrel 21 when the value is a predetermined value S1. The standard adhesion degree is determined for each point type of the branching device 2. For example, in a normal point, when the gap amount S is 1 mm, it is 980 N (100 kgf). In order to prevent the Tongler 21 from separating from the basic rail 23 when the vehicle passes through the branching device 2, the degree of adhesion is regularly measured during maintenance of the branching device 2.

  Conventionally, an adhesion degree measuring device for measuring the adhesion degree is known (see, for example, Patent Document 1). Such an adhesion measuring device has a pusher mounted between the Tongler 21 and the basic rail 23, and the pusher is driven by a hydraulic pump so that there is a gap between the tip of the Tongler 21 and the basic rail 23. And the pressing force of the Tongleil 21 is measured by measuring the hydraulic pressure. However, in the measurement of the degree of adhesion using this degree-of-adhesion measuring device, the gap amount S between the tip of the tongue rail 21 and the basic rail 23 is adjusted to a predetermined value S1 by an operator measuring with a gap gauge. The measurement work is complicated.

(First embodiment)
An adhesion measuring device according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and FIG. As shown in FIG. 7, the contact degree measuring device measures the contact degree at which the Tongrel 21 and 22 in the branching device 2 are in close contact with the basic rails 23 and 24. As shown in FIGS. 1A and 1B and FIG. 2, the adhesion measuring device 1 of the present embodiment includes a gap setting unit 3 and a pressing force measurement unit 4. The gap setting unit 3 spreads the gap between the tongrel 21 and the basic rail 23 from the state where the tongrel 21 is in close contact with the basic rail 23, and the gap between the tip of the tongrel 21 and the basic rail 23. The amount S is set to a predetermined value S1. The pressing force measuring unit 4 measures the force with which the gap setting unit 3 is pressed from the tongrel 21. The force with which the gap setting portion 3 is pressed from the Tongrel 21 is the same as the force with which the gap setting portion 3 pushes between the Tongler 21 and the basic rail 23 according to the law of action and reaction. The force measured by the pressing force measurement unit 4 when the gap amount S is the predetermined value S1 is the degree of adhesion.

  Even in the state where the tongrel 21 and 22 are converted and the other tongrel 22 is in close contact with the other basic rail 24, the contact degree measuring device 1 similarly measures the degree of contact.

  A front rod 25 is provided at the tips of the tongue rails 21 and 22 (see FIG. 7). The front rod 25 has elbows 26 at both ends, and is attached to the tips of the tongrels 21 and 22 via the elbows 26. When the tongue rail 21 is in close contact with the basic rail 23, the elbow 26 of the front rod 25 and the abdomen of the basic rail 23 are separated from each other. As shown in FIG. 3, the gap setting unit 3 is sandwiched between the elbow 26 of the front rod 25 and the abdomen 231 of the basic rail 23, and pushes the tongrel 21 through the elbow 26. When the tongue rail 21 is pushed, the space between the tongue rail 21 and the basic rail 23 is pushed wide, and a gap (opening) is generated between the tip of the tongue rail 21 and the basic rail 23.

  The gap setting unit 3 is made of metal, and includes a main body 31, a movable unit 32, and a pressing unit 33 in this order. The main body 31 has a recess 311 that engages with the elbow 26, and abuts on the elbow 26. The movable part 32 is provided so as to be able to advance and retreat relative to the main body 31, and does not rotate. The movable portion 32 can be advanced and retracted so that the force applied between the main body 31 and the movable portion 32 can be measured. Even if a force is applied between the main body 31 and the movable portion 32, the movable portion 32 is not displaced with respect to the main body 31. The pressing portion 33 contacts the basic rail 23 and presses the movable portion 32.

  The movable part 32 is formed with a cap screw 321 on the side facing the basic rail 23. The pressing portion 33 has a screw 331 screwed to the cap screw 321 formed on the outer peripheral surface, and is screwed to the movable portion 32 so as to be able to advance and retreat. The pressing portion 33 presses the movable portion 32 by being rotated in one direction, and sets the gap amount S to a predetermined value S1 by being rotated by a predetermined rotation angle θ. In the present embodiment, the cap screw 321 and the screw 331 are formed so that the gap amount S when the rotation angle θ is 90 ° is a predetermined value S1 = 1 mm. The rotation angle θ of the pressing portion 33 is confirmed visually. Scales 322 for confirming the rotation angle θ of the pressing portion 33 are radially formed on the surface of the movable portion 32 facing the basic rail 23 (see FIG. 2). The pressing force measurement unit 4 measures the force between the main body 31 and the movable unit 32.

  The main body 31 of the gap setting unit 3 has a cylinder 312 on the side facing the basic rail 23. The movable part 32 is a piston inserted into the cylinder 312. The gap setting unit 3 seals the liquid 41 in the cylinder between the cylinder 312 of the main body 31 and the movable unit 32. The movable part 32 has an O-ring 323 for sealing the liquid 41. Since the liquid 41 is sealed and its volume does not change, even when a force is applied between the main body 31 and the movable portion 32, the movable portion 32 is not displaced with respect to the main body 31. In the present embodiment, the liquid 41 is oil. The pressing force measurement unit 4 includes a hydraulic pressure gauge 42 that measures the pressure of the liquid 41 and a member that supports the hydraulic pressure gauge 42 on the gap setting unit 3. The hydraulic pressure gauge 42 has a display unit 421 that displays measured values. The display unit 421 is supported so as to be convertible with respect to the gap setting unit 3. In the present embodiment, the hydraulic pressure gauge 42 is a hydraulic pressure gauge, and displays a value obtained by converting the measured hydraulic pressure into a force.

  The main body 31 and the movable part 32 only need to be able to seal the liquid 41 for pressure measurement. Contrary to the present embodiment, the movable part 32 may be a cylinder and the main body 31 may be a piston (not shown). ).

  The pressing portion 33 has an adjustment bolt 332 that can be advanced and retracted on the side facing the basic rail 23. The adjustment bolt 332 is provided to facilitate application to a plurality of different types of branching devices 2, and the pressing portion 33 is provided on the abdomen 231 of the basic rail 23 in a state where the tongrel 21 is in close contact with the basic rail 23. Used to adjust to abut. The adjustment bolt 332 may be omitted and the pressing portion 33 may be integrated. In that case, the adjustment for bringing the pressing portion 33 into contact with the abdomen 231 of the basic rail 23 is performed only by the rotation of the pressing portion 33.

  The adhesion measuring device 1 configured as described above is carried by a measurer and used for measuring the adhesion of the branching device 2. When one of the tongrels 21 is in close contact with one of the basic rails 23, the gap setting unit 3 is disposed between the abdomen 231 of the basic rail 23 and one of the elbow bars 26. The main body 31 of the gap setting unit 3 engages with and comes into contact with the elbow 26 by the recess 311. The display unit 421 of the hydraulic pressure gauge 42 protrudes above the gap setting unit 3 and is turned so that the measured value displayed on the display unit 421 can be easily seen by the measurer. The measurer turns the pressing portion 33 to bring the pressing portion 33 into contact with the abdomen 231 of the basic rail 23. The adjustment bolt 332 may be turned to bring the pressing portion 33 into contact with the abdomen 231 of the basic rail 23. At this time, the tongrel 21 is in close contact with the basic rail 23 and the gap amount S is zero.

  The measurer further turns the pressing portion 33 with a tool such as a spanner. The pressing portion 33 presses the movable portion 32 toward the main body 31 by this rotation. The force is transmitted from the pressing portion 33 to the movable portion 32, the liquid 41, the main body 31, the elbow metal 26, and the tongrel 21. Therefore, the gap setting unit 3 pushes the gap between the Tongle rail 21 and the basic rail 23. The measurer stops turning when the pressing portion 33 is turned by a predetermined rotation angle θ = 90 °. At this time, the gap amount S between the tip of the Tongrel 21 and the basic rail 23 is set to a predetermined value S1 = 1 mm by the gap setting unit 3. Since the gap amount S is determined by the rotation angle θ, it is not necessary to measure with a gap gauge or the like. Note that the gap amount S with respect to the rotation angle θ is an example, and is not limited to this.

  The pressing force of the tongue rail 21 is transmitted from the Tongrel 21 to the elbow metal 26, the main body 31, and the liquid 41. The hydraulic pressure gauge 42 measures the pressure of the liquid 41 and displays it on the display unit 421 as the degree of adhesion.

  Next, the tonglers 21 and 22 of the branching device are converted by a rolling machine (not shown), and the other tongley 22 is brought into close contact with the other basic rail 24. The degree of adhesion of the Tongrel 22 is similarly measured using the degree-of-adhesion measuring instrument 1.

  As described above, according to the adhesion measuring instrument 1 according to the present embodiment, the gap setting unit 3 sets the gap amount S between the tip of the tongue rail 21 and the basic rail 23 to the predetermined value S1, so that the branching device 2 In the measurement of the degree of adhesion, the measurement of the gap amount S becomes unnecessary. Since the pressing force measuring unit 4 measures the force with which the gap setting unit 3 is pressed from the tongrel 21, the pressing force measuring unit 4 can measure the pressing force of the tongrel 21 when the gap amount S is the predetermined value S1, that is, the degree of adhesion. it can. Since there is no need to measure the gap amount S with a gap gauge or the like, by using the adhesion measuring device 1 of the present embodiment, one measurer can easily measure the adhesion accurately and with little variation. .

  When the tongue rail 21 is in close contact with the basic rail 23, the elbow 26 of the front rod 25 and the abdomen 231 of the basic rail 23 are separated from each other. It can be sandwiched between the abdomen 231 and the tongrel 21 can be pushed through the elbow 26.

  The gap setting unit 3 widens the gap between the tongue rail 21 and the basic rail 23 by turning the pressing unit 33 by a predetermined rotation angle θ, and sets the gap amount S to the predetermined value S1. The quantity S can be easily set to the predetermined value S1.

  The pressure of the liquid 41 sealed between the main body 31 and the movable part 32 of the gap setting unit 3 is increased by the force with which the gap setting unit 3 is pressed from the tongrel 21, and the pressure of the liquid 41 is measured by the hydraulic pressure gauge 42. Therefore, the pressing force measuring unit 4 can accurately measure the force with which the gap setting unit 3 is pressed from the tongrel 21.

  Since the pressing portion 33 of the gap setting portion 3 has an adjustment bolt 332 that can be advanced and retracted so as to adjust to contact the abdomen 231 of the basic rail 23 in a state where the tongrel 21 is in close contact with the basic rail 23, Application of the adhesion measuring device 1 to the different types of branching devices 2 becomes easy.

  Since the main body 31 of the gap setting portion 3 has the recess 311 that engages with the elbow 26, it can be easily brought into contact with the elbow 26.
