Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesion degree measuring instrument and an adhesion degree measuring method used to measure the degree of adhesion between a tongue rail of a turnout for selecting a route of a vehicle and a base rail.

First, a general configuration of a turnout structure for selecting the course of a railroad vehicle will be described with reference to FIG. For example, there is a rolling iron device described in Non-Patent Document 1 below (see FIG. 1) as a rolling iron device serving as a point portion of a turnout. This point device is composed of a switching device and a locking device, and is operated by an electric point machine 101 . Here, the conversion device brings the tongue rail 110 into close contact with or separates from the fixed basic rail 109, while the locking device keeps the tongue rail 110 and the basic rail 109 in close contact. is.

The electric point machine 101 is installed on a sleeper 100 extending to the outside of the track (outside between the pair of basic rails 109). The electric point machine 101 transmits a driving force from an AC motor 108, which is a driving source, to a clutch, a reduction gear, and a conversion gear with a conversion roller (not shown) in this order, and the operation stick 102 is driven by the conversion roller. move.

The motion stick 102 linearly moves in a direction orthogonal to the basic rail 109 by moving a cam (not shown) connected to the motion stick 102 by a changeover roller (not shown). The electric point machine 101 is fixed to a switch adjuster 103 connected to an operation stick 102, an arm fitting 111 of the switch adjuster 103, a rolling iron bar 104 connected to the arm fitting 111, and a tongue rail 110. The tongue rail 110 is converted by the connecting fitting 112, and whether or not the tip of the converted tongue rail 110 is in a normal position is checked by the front rod 105, the connection pin 106 and the lock pin 107. If the tip of the tongue rail 110 is in a normal position, the operating lever 102 and the locking lever 107 are locked by a cam bar (lock piece) (not shown).

Various inspections and measurements are performed on the turnout structure as described above. For example, in the conventional adhesion degree measuring device described in Patent Document 1 below, it is measured whether or not the tongue rail is pushed by a switch adjuster and adheres to the basic rail at an appropriate degree. Specifically, a pusher is installed in the gap between the tongue rail and the base rail from the tip side of the tongue rail. In this state, when the pusher is operated by the hydraulic pump, the tongue rail is forcibly pulled away from the base rail, so the force (adhesion) that the pusher tries to open the tongue rail at that time will affect the tongue rail and the base rail. The degree of close contact (strength with which the switch adjuster pushes the tongue rail) is measured with a pressure gauge. How wide the gap between the tongue rail and the base rail is is measured by a clearance gauge or the like. The appropriate degree of opening between the tongue rail and the base rail when measuring the degree of adhesion varies depending on the type of turnout. measured.

However, with the above-described conventional adhesion measuring instrument, it is necessary to use a feeler gauge to measure the degree of opening between the tongue rail and the basic rail and whether it is suitable for measuring the degree of adhesion, which is a complicated operation. In addition, the maintenance work of turnouts requires a smaller and lighter measuring instrument due to the special nature of the need for workers to move on the track on foot.

It has an operating part that moves forward or backward with respect to the cylinder of the pump, a gauge part for indicating the position of the operating part with respect to the piston pump, and a measuring part connected to the piston pump. When the operation part is operated, the piston cylinder is operated according to the amount by which the piston of the piston pump is pushed forward, and the gap between the tongue rail and the base rail is widened. Based on Pascal's principle, the stroke of the operating part advanced with respect to the piston pump and the stroke of the piston cylinder have a certain relationship. stroke is also calculated. That is, the amount by which the gap between the tongue rail and the base rail is widened (the stroke of the piston cylinder) is calculated from the gauge section (the stroke of the operation section).

Fits in the gap. That is, since the width of the piston cylinder at the start of measurement differs for each measurement, the positions of the piston and the operating portion of the piston pump at the start of measurement also differ for each measurement. In the present invention, since the gauge portion is movable, the position of the gauge portion is adjusted according to the position that serves as a reference for the stroke of the operating portion at the time of starting measurement.

In the adhesion degree measuring instrument according to the present invention, the gauge section has the positioning section. Therefore, it is possible to prevent the gauge portion from being unintentionally displaced during measurement.

BEST MODE FOR CARRYING OUT THE INVENTION An adhesion degree measuring device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 2 and FIG. 3 are cross sections of essential parts of the adhesion degree measuring device 1 according to the embodiment of the present invention, showing a state in which the adhesion degree measuring device 1 is installed in the gap between the tongue rail 110 and the base rail 109. FIG. It is FIG. 2 shows the state before the adhesion measuring device 1 operates, and FIG. 3 shows the state after the adhesion measuring device 1 operates. In the following description, the front end side of the tongue rail 110 is the front side, the opposite side is the rear side, and the height direction of the basic rail 109 is the upper side or the lower side. However, the relative movement direction of the piston is forward or backward, with the forward side being the front part and the backward side being the rear part.

As shown in FIGS. 2 and 3, the adhesion measuring device 1 is for measuring the degree of adhesion of the tongue rail 110 to the base rail 109 (hereinafter referred to as "adhesion"). The adhesion degree measuring device 1 includes a pusher 2 as a hydraulic piston cylinder installed in a gap S between the tongue rail 110 and the base rail 109 to expand the gap S, and the pusher 2 is connected via a hose 6. and a hydraulic gauge 26 as a measuring unit connected to the pump device 7 . The oil pressure gauge 26 measures pressure, and the unit is Newton (N), which represents the load.

The pusher 2 is circular as viewed from the rails 109 and 110 and has a pusher piston 3 and a pusher cylinder 4 . The pusher piston 3 is housed in the pusher cylinder 4 by being projected or retracted from the pusher cylinder 4 toward the tongue rail 110 by hydraulic pressure. The pusher cylinder 4 has a spacer 5 attached to and detached from the basic rail 109 side according to the clearance S. The hose 6 is, for example, a flexible pipe made of metal, made of resin, or the like.

The pump device 7 has a cylindrical shape and is made of, for example, brass or stainless steel. The pump device 7 has a piston pump 8 , an operating portion 22 connected to the piston pump 8 , and a gauge portion 23 arranged between the piston pump 8 and the operating portion 22 .

The piston pump 8 comprises a cylinder 9, a closing cover 13 connected to the front of the cylinder 9, a piston 10 moving forward or backward in the cylinder 9, and a long bolt connected to the rear of the piston 10. and a cylindrical lid portion 15 into which the bolt portion 18 is inserted and which is connected to the rear portion of the cylinder 9 .

The cylinder 9 is cylindrical and has an oil chamber inside. Threads are formed on the front and rear outer peripheries of the cylinder 9, respectively. The closing lid portion 13 has a cylindrical shape and a closed front portion. A hose 6 and a hydraulic gauge 26 are connected to the holes 14a and 14b of the closing cover 13, which are vertically open. A piston 10 is fitted with an O-ring 11 and has a hole 12 formed in its rear portion. Two spring pins (not shown) are attached to the hole 12 in a direction perpendicular to the hole 12 . The bolt portion 18 has a hexagonal head portion 19 and a threaded leg portion 20 , and an annular groove portion 21 is formed at the tip of the leg portion 20 . The tip of the leg portion 20 is inserted into the hole 12 of the piston 10 and the spring pin is engaged with the groove portion 21 . With this configuration, when the bolt portion 18 rotates, the leg portion 20 idles in the hole 12 relative to the piston 10 and the piston 10 does not rotate. The cylindrical lid portion 15 has a cylindrical shape, open front and rear portions, and has two different outer diameters. The front portion of the cylinder lid portion 15 is a large diameter portion 16 with a large outer diameter, and the rear portion of the cylinder lid portion 15 is a small diameter portion 17 with a small outer diameter. The large-diameter portion 16 has a screw groove formed on the inner periphery thereof to be screwed with the screw thread at the rear portion of the cylinder 9 . The small-diameter portion 17 has a thread groove formed on the inner periphery thereof to be screwed with the thread of the bolt portion 18 .

The gauge portion 23 has an annular movable portion 24 and a thin plate-like scale portion 25 . The movable portion 24 is inserted into the small diameter portion 17 of the cylinder lid portion 15 and is movable along the small diameter portion 17 . A front portion of the scale portion 25 is fixed to the outer peripheral surface of the movable portion 24 . A scale is displayed on the upper surface of the scale portion 25 . The scale indicates the position of the operating part 22 with respect to the piston pump 8, and is for confirming the stroke of the operating part 22. For example, it is "0", "0.5", "1", etc. (see FIG. 4). . The scale portion 25 has a round hole for each scale, and the range of the scale is specified by the round hole. The gauge portion 23 has a positioning portion (not shown). The positioning part is, for example, an O-ring, a bolt, or the like. The O-ring is attached to the inner peripheral surface of the movable portion 24 and retains the gauge portion 23 by frictional force with the small-diameter portion 17 . The bolt passes through the movable portion 24 from the outside toward the inside. That is, when the bolt rotates and the tip of the bolt reaches the small diameter portion 17, the gauge portion 23 is held in position.

The operation part 22 has a cylindrical shape and a closed rear part, through which holding bolts 27a and 27b extend from the outside to the inside. The small diameter portion 17 of the cylinder lid portion 15 is inserted into the operation portion 22 together with the bolt portion 18 . The head 19 of the bolt portion 18 is locked by gripping bolts 27a and 27b. The front end of the operating portion 22 is flat and annular.

When the operation portion 22 rotates, the bolt portion 18 also rotates, and the operation portion 22 moves forward or backward relative to the piston pump 8 along the small diameter portion 17 of the cylinder lid portion 15 . At the same time, the piston 10 connected to the bolt portion 18 moves forward or backward within the cylinder 9 . When the piston 10 advances, the pusher 2 is operated by hydraulic pressure, and the pusher piston 3 protrudes. The pusher 2 pushes the gap S between the tongue rail 110 and the basic rail 109 . The tongue rail 110 is forced away from the base rail 109 . The degree of adhesion can be known from the load at that time. Here, since the appropriate degree of opening between the tongue rail 110 and the basic rail 109 in measurement (hereinafter referred to as "optimal opening") differs for each turnout, the clearance gauge 28 The optimum degree of opening is confirmed by being inserted between and, in the adhesion degree measuring instrument 1, the optimum degree of opening is grasped by the gauge portion 23. As shown in FIG.

Here, the method of measuring the degree of adhesion according to the present embodiment using the degree of adhesion measuring device 1 will be described together with how to use the gauge section 23. FIG. 4 to 6 show the process of operation of the adhesion measuring device 1. FIG. 4 shows the initial state before the adhesion measuring device 1 is attached to the gap S between the tongue rail 110 and the basic rail 109, and FIG. 5 shows the initial setting after the adhesion measuring device 1 is attached to the gap S. FIG. 6 shows an initial setting state in which the adhesion degree measuring device 1 is in operation. 4 to 6, the tongue rail 110 and the base rail 109 are omitted.

As shown in FIG. 4 , in the initial state, the operating part 22 is arranged at the rearmost part, and the piston 10 is also arranged at the rearmost part in the cylinder 9 . The pusher piston 3 is retracted and housed in the pusher cylinder 4. The oil pressure gauge 26 at this time indicates that the degree of adhesion is zero. In the initial state, the pusher 2 is installed in the gap S between the tongue rail 110 and the basic rail 109 . A spacer 5 is attached to the pusher cylinder 4 as necessary (see FIGS. 2 and 3).

As shown in FIG. 5, the gauge portion 23 is aligned with the reference position B in the initial setting state. More specifically, when the operation part 22 is operated and moves forward while rotating, the piston 10 also moves forward in the cylinder 9 at the same time. Note that the piston 10 does not rotate. The pusher piston 3 protrudes slightly due to hydraulic pressure. At the moment when the pusher piston 3 pushes the tongue rail 110 very slightly and the needle of the oil pressure gauge 26 moves slightly, or shortly thereafter (for example when the needle reaches the first scale on the oil pressure gauge 26), The rotation of the operation part 22 is stopped. This position is the reference position B of the operation unit 22 . The gauge portion 23 is moved to a position where “0” displayed on the scale portion 25 is aligned with the front end of the operation portion 22 . More specifically, in the range of the round hole at "0", the front end of the operating portion 22 is aligned with the center of the round hole. The gauge portion 23 is fastened to the small diameter portion 17 of the piston pump 8 with a locating portion.

As shown in FIG. 6, the operating part 22 is aligned with the measuring position M in the operating state. Specifically, when the operating portion 22 is further operated, the operating portion 22 advances while rotating to approach the gauge portion 23 . The front end of the operation part 22 is aligned with the position of "1" displayed on the scale part 25 with respect to the gauge part 23 where the position where the display of the scale part 25 is "0" is aligned with the front end of the operation part 22. , the operation unit 22 is stopped. This position is the measurement position M of the operation unit 22 . As the operating portion 22 advances, the piston 10 also advances inside the cylinder 9, and the pusher piston 3 protrudes due to hydraulic pressure. The pusher piston 3 pushes the tongue rail 110 and widens the gap S between the tongue rail 110 and the basic rail 109 .

Here, if the meaning of the round hole of the scale part 25 is explained in detail, the round hole has an area compared to a simple line, and has a range according to the area. , the front end of the operation unit 22 is arranged on the front side of the center, on the center side, on the back side of the center, or the like, so that fine adjustment is possible. When the operator knows which position in the round hole is arranged among "1" and "0.5" of the scale part 25, it becomes a guideline when repeatedly measuring, and the work becomes smooth. .

The stroke S1 of the operation part 22 advanced with respect to the piston pump ₈ and the stroke _S2 of the pusher 2 have a constant relationship based on Pascal's principle. For example, if the standard of the bolt portion 18 is M10, the pitch of the bolt portion 18 is generally 1.5 millimeters, so the bolt portion 18 advances by 3 millimeters with two rotations. If the ratio between the pusher 2 and the piston pump 8 is 1:3, the pusher piston 3 will protrude by 1 mm if the bolt portion 18 advances by 3 mm.

If the range from "0" to "1" is set to 3 millimeters in the gauge section 23, by shifting the measurement position M of the operation section 22 from which the reference position B is set to "0" to "1", The stroke _S1 of the operating part 22 is 3 mm, and the stroke _S2 of the pusher 2 is 1 mm. In this case, the gap S between the tongue rail 110 and the basic rail 109 is expanded by 1 mm. Further, if the measurement position M is shifted to "0.5", the stroke _S1 of the operating part 22 is 1.5 mm, and the stroke _S2 of the pusher 2 is 0.5 mm. In this case, the gap S is expanded by 0.5 mm. That is, if the optimum opening is 1 mm, the measurement position M should be set to "1", and if the optimum opening is 0.5 mm, the measurement position M should be set to "0.5".

There are various methods of displaying the scale portion 25 . In addition to displaying the optimum opening degree as in the present embodiment, the stroke _S1 of the operation unit 22 may be indicated as "1 mm,""2mm," and "3 mm." Further, the scale part 25 may be, for example, a general scale without round holes such as a ruler.

This embodiment is configured as described above. Next, the effects of this embodiment will be described.

As described above, the adhesion measuring device 1 includes a pusher 2 installed in the gap S between the tongue rail 110 and the basic rail 109 to widen the gap S, and a pump connected to the pusher 2 via the hose 6. It has a device 7 and a hydraulic gauge 26 connected to the pump device 7 . The pump device 7 includes a piston pump 8, an operation portion 22 connected to the piston pump 8, and a gauge passed through the small diameter portion 17 of the piston pump 8 and arranged between the large diameter portion 16 and the operation portion 22. 23 (see FIGS. 2 and 3). Therefore, the structure of the adhesion degree measuring device 1 is simple.

Also, with this configuration, when the operating portion 22 rotates and advances, the piston 10 also advances in the cylinder 9 at the same time, and the pusher piston 3 slightly protrudes due to hydraulic pressure and pushes the tongue rail 110 very slightly. The rotation of the operation part 22 is stopped at the moment when the needle of the oil pressure gauge 26 moves slightly or immediately after that. The gauge portion 23 is moved to this reference position B, and "0" displayed on the scale portion 25 is aligned with the front end of the operation portion 22 and stopped (see FIG. 5). The operation part 22 is further operated, and the front end of the operation part 22 is aligned and stopped at the measurement position M (see FIG. 6). As the operating portion 22 advances, the piston 10 also advances inside the cylinder 9, and the pusher piston 3 protrudes due to hydraulic pressure. The pusher piston 3 pushes the tongue rail 110, and the clearance S is expanded.

That is, the optimum opening degree can be easily grasped from the gauge portion 23 (the stroke S ₁ of the operation portion 22). Therefore, simple work can be realized.

The gauge portion 23 is movable along the small diameter portion 17 of the piston pump 8 . Therefore, "0" of the scale portion 25 in the gauge portion 23 can be aligned with the reference position B for each turnout or each measurement.

The gauge portion 23 has a locating portion. Therefore, it is possible to prevent the gauge portion 23 from being unintentionally displaced during measurement.

The gauge part 23 has a scale part 25 on which scales of "0", "0.5", and "1", which are strokes _S2 of the pusher 2, are displayed. Therefore, the optimum opening degree can be easily grasped from the scale portion 25 .

The scale portion 25 of the gauge portion 23 has a round hole for each scale, and the range of the scale is specified by the round hole. Therefore, it is easy to see that the front end of the operating portion 22 is aligned with the scale. Further, fine adjustment is possible by arranging the front end of the operation part 22 on the front side of the center, on the center side, on the back side of the center, or the like in the round hole. The gap between the tongue rail and the base rail before measurement varies depending on the type and condition of the turnout. For example, when a feeler gauge is also used, the position of the front end of the operation part 22 in the round hole of the scale part 25 allows the feeler gauge to enter the gap between the tongue rail and the base rail ( That is, the operator can know whether the clearance is 1 mm or 0.5 mm by actual measurement with a clearance gauge. This experience becomes a guideline for the work when repeated measurements are performed, and the work becomes smoother.

The piston pump 8 comprises a cylinder 9, a closing lid portion 13 connected to the front portion of the cylinder 9, a piston 10 moving forward or backward in the cylinder 9, and a bolt portion 18 connected to the rear portion of the piston 10. and a cylindrical lid portion 15 connected to the rear portion of the cylinder 9 into which the bolt portion 18 is inserted. That is, since the piston pump 8 has a simple structure, it can be reduced in size and weight. Specifically, the adhesion measuring device 1 weighs approximately 1.5 kilograms. Further, in the adhesion degree measuring device 1, the operation of rotating the operation part 22 to advance the cylinder 9 together, and the operation of pushing the tongue rail 110 with the pusher 2 are easy for the operator to intuitively grasp. In addition, if the operation unit has a structure like a hand pump in a well, it is difficult to grasp the operation of the pusher from the operation of the hand pump.

Note that, as another embodiment of the present invention, there is also an adhesion measuring device without a positioning portion. Also, as another embodiment, a magnet may be attached to the outer surface of the cylinder 9 . If there is a magnet, the adhesion measuring device is magnetically fixed to the tongue rail 110 or the like, which is convenient for measurement.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. Various design changes can be made to the present invention without departing from the scope of the claims.
