2. Description of the Related Art As shown in FIG. 3, a conventional tong rail abrasion measuring device is provided with a pressing plate 4 formed so as to press against a bottom portion 2 and an abdominal portion 3 of a tong rail 1. A support plate 6 having a grip portion 5 is provided at the center of the plate 4, and a pair of calipers 7 and 8 having different scales are attached to the upper end of the support plate 6.

The amount of wear was measured.

In such a measurement, the measuring instrument may be displaced during the measurement by a person who performs the measurement, and for example, the scale 11 of the main scale of the caliper 7 and the scale 12 of the vernier scale are complicated, and the reading is not possible. There is a drawback that errors may occur in the measurement (individual differences) and the accuracy of the measurement tends to be inaccurate because mistakes may occur. The present invention seeks to provide a switch tong rail wear meter that can overcome such disadvantages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 13 denotes a plastic machine frame, which has a tongue rail T (a part of the bottom is indicated by a hatched line S in FIG. 1). Of the cut surface 15 formed by cutting the crown portion 14 of FIG. 1), a rounded edge portion 17 formed so as to be in close contact with the rounded cut surface 16, and a crown portion of the tongue rail T 14 and a pair of side plates 19A and 19B having a separation edge 18 formed so as to be separated from a cutting surface continuous with the round cutting surface 16 at a distance 20 between the upper edges. A top plate 33 is provided.

On the inner walls of the pair of side plates 19A and 19B of the machine frame 13, iron pieces 20A and 20B formed so as to be in close contact with the rounded surface 16 of the tongue rail T are bonded with an adhesive. Fix it. Between the iron pieces 20A and 20B, a disk-shaped permanent magnet 22 formed so as to form a gap 21 between the rounded surface 16 of the tongue rail T is fixed by bonding with an adhesive, and the permanent magnet is fixed. A portion other than the magnet 22 is packed with an aluminum material or other non-permeable plate 40.

On one of the side plates 19A and 19B, for example, on the outer wall of the side plate 19A, slide the battery (omitted in the figure) and the tip 23 against the cut surface near the top 14 of the tong rail T. A digital measuring instrument 27 incorporating an electronic circuit (omitted in the drawing) designed to display a measured numerical value 25 in proportion to the sliding amount of the measuring scale 24 to be displayed through a window frame 26 is attached. In FIG. 1, 28 is a ZERO / ABS push button switch (selection of absolute value measurement (ABS), measurement from the origin of the measuring instrument) electrically connected to the electronic circuit, and 29 is electrically connected to the electronic circuit. ON / OFF push button switch (comparison measurement (INC), measurement by setting zero at any point). Reference numeral 30 denotes a battery cover. Reference numeral 31 denotes a scale displayed along a side corresponding to the top portion 14 of the tongue rail T of the side plate 19A, and a head width based on a gauge line 14 mm below the top surface of the tongue rail T is indicated. It is to be measured. Reference numeral 32 denotes a scale displayed along the side corresponding to the cut surface 15 of the tongue rail T in the side plate 19A, and measures the cut depth based on the top surface of the tongue rail T. Reference numeral 34 denotes an ORIGIN push-button switch electrically connected to the electronic circuit (sets the origin of the measuring instrument. It does not change even if the power is turned ON / OFF. Set when replacing the battery). Reference numeral 35 denotes a HOLD push button switch electrically connected to the electronic circuit (to hold a measured value and to store the measured value, and set the measured value to a held state).

In the tong rail wear measuring device having the above-described configuration, the rounded edge 17 of the machine frame 13 is manually pressed against the R-shaped cut surface 16 of the tong rail T. Then, the machine frame 13 is fixed to the cut surface of the tongue rail T by the strong magnetic force acting between the permanent magnet 22 and the edges of the iron pieces 20A and 20B, and the entire measuring instrument is fixed to the tongue rail T. Therefore, the measuring rule 24 of the digital measuring instrument 27 is fixed to a cutting surface near the top of the tongue rail T at the tip 23 (a fixed size from the top of the tongue rail T where the rail head is not cut). (For example, a position lowered by 14 mm). Then, the measured value 25 proportional to the sliding amount is displayed through the window frame 26 of the digital measuring instrument 27, and the wear amount of the tongue rail T on the side of the head to be measured can be read at a glance.

The present invention is not limited to the above embodiment, and an electromagnet or the like may be used instead of the permanent magnet 22. Further, a magnetically permeable plate formed of a material having magnetic permeability may be used instead of the iron pieces 20A and 20B. Further, the pair of side plates 19A and 19B are entirely formed of an aluminum or other non-permeable plate 40 without the iron pieces 22A and 22B, or the permanent magnet 22 is made of an iron plate, and the iron plate is made of an aluminum or other transparent material. In some cases, the pair of side plates 19A and 19B are formed by adding magnetic plates. The space between the pair of side plates 19A and 19B may be an aluminum material or other non-permeable plate, or may be a space, except for the permanent magnet 22.

[0013]

[Effect of the Invention] In the invention according to the first aspect, since the entire digital measuring instrument is strongly fixed to the tongue rail by the magnetic force of the magnet, the digital measuring instrument does not deviate during the measurement. The wear measurement values can be read at a glance through the window frame of the digital measuring instrument, so that the measurement accuracy is accurate and there is no error (individual difference) between the measurers. In addition, since a pair of side plates of the machine frame are provided with separation edges formed so as to be separated from the top of the tongue rail and the cutting surface which is continuously connected to the R-shaped cutting surface, the tongue rail is in use. The bulge swells from the top of the head so that it hangs down on the cut surface. In the invention according to claim 2, the edges of the pair of magnetically permeable plates are in close contact with the rounded surfaces of the tongue rail, and the edges of the magnet fixed between the pair of magnetically permeable plates and the R-shaped cutout of the tongue rail. Since a gap is formed between the magnet and the surface, the magnetic force acting between the edges of the pair of magnetically permeable plates is stronger than the magnetic force when the magnet edges are brought into direct contact with the rounded surface of the tongue rail. And the fixing of the measuring instrument to the tongue rail is further stabilized.
