Description

  The present invention relates to a sliding plate wear measuring instrument that is applied to a pantograph that slides on a trolley wire on a track and can easily check the wear level of the sliding plate.

In the railway field, a pantograph used as a current collector for a train or the like is provided with a sliding plate that comes into contact with a trolley wire on the track.
In this sliding plate, wear occurs due to contact and sliding with the trolley wire as the train travels. For this reason, it is necessary to periodically measure the wear amount of the sliding plate and replace the sliding plate when the wear amount exceeds the wear limit.
Such replacement of the sliding plate is often performed based on on-site empirical judgment, and if the judgment is wrong, a trouble may occur.

In order to solve such problems, there is provided a technique for knowing when to replace the sliding plate without relying on field experience. For example, a wear amount measuring apparatus disclosed in Patent Document 1 provides a technique for measuring the wear amount of a contact portion while relatively moving the first contact portion and the second contact portion in a contact state.
Specifically, in the wear amount measuring device, the first displacement amount measuring unit that measures the displacement amount of the non-friction portion of the first contact portion with reference to the fixed point, and the second contact with respect to the fixed point. A second displacement amount measuring unit for measuring the displacement amount of the non-friction part, and a third displacement amount measuring unit for measuring the displacement amount of the friction part of the first and second contact portions with reference to the fixed point; The wear amount calculation unit calculates the wear amount of each contact portion based on the measurement results of the first to third displacement amount measurement units.

JP2011-209187A

  However, the wear amount measuring device disclosed in Patent Document 1 has a complicated configuration such as providing a wear amount calculation unit that calculates the wear amount of each contact portion based on the measurement results of the first to third displacement amount measurement units. Therefore, it was expected that a simple wear amount measuring device would be provided.

On the other hand, the trolley wire is installed in zigzags on the left and right on the track in order to equalize the wear of the sliding plate. Therefore, when the train travels, the trolley line moves while swinging left and right on the sliding plate.
The wear generated in the sliding plate S at this time can be classified into a curved normal wear shown in FIG. 5 (A) and a stepped wear shown in FIG. 5 (B). In the latter step wear, stepped hooks formed at predetermined locations gradually increase, and finally become V-shaped stepped grooves 10 as shown in FIG.
When such a stepped groove 10 is formed, it is particularly difficult to determine the replacement time of the sliding plate S, and it has been desired to provide a new technique that can easily determine the replacement time of the sliding plate. In addition, the code | symbol M shown in FIG. 5 is the trolley line which slides with the sliding board S. FIG.

  The present invention has been made in view of the above-described circumstances, and in the case where a stepped groove is formed in the sliding plate, a sliding plate wear measuring instrument that can determine the replacement timing of the sliding plate with a simple configuration. I will provide a.

In order to solve the above problems, the present invention proposes the following means.
The present invention is a sliding plate wear measuring instrument that is disposed on a front or rear side surface of a sliding plate orthogonal to a trolley wire and is aligned with an inclined line of a stepped groove caused by wear of the sliding plate. A plate-like member that is formed of a transparent plate and that is positioned so that a bottom portion located at the lower end thereof is along the side surface length direction of the slide plate, and is formed on the plate surface of the plate-like member and wear of the slide plate And a reference inclination line that serves as a criterion for determining whether or not the sliding plate has reached the replacement time.

And according to the said device, the judgment criteria as to whether or not the sliding plate has reached the replacement time by comparing with the inclined line of the stepped groove caused by the wear of the sliding plate on the plate surface of the plate-like member, Therefore, when the operator compares the inclined line of the stepped groove with the reference inclined line, the wear generated on the sliding plate is changed at the time of replacement of the sliding plate. You can easily know if you have reached it.
That is, in the present invention, when a stepped groove is formed in the sliding plate, it is possible to easily determine the replacement timing of the sliding plate with a simple configuration without using a complicated mechanism such as a sensor and a calculation means. Become.

  Further, in the present invention, there is provided a sliding plate wear measuring instrument that is disposed on the front or rear side surface of the sliding plate orthogonal to the trolley wire and is aligned with the inclined line of the stepped groove caused by the wear of the sliding plate. A plate-like member formed by a transparent plate and positioned at the bottom of the bottom plate so as to extend along the side surface length direction of the slide plate; and the slide formed on the upper edge of the plate-like member. It has a reference inclination edge part used as a judgment standard whether the above-mentioned sliding board reached replacement time by contrasting with the inclination line which arose by abrasion of a board.

And according to the said device, it is judged whether the said sliding plate reached the replacement time by contrasting with the inclined line of the stepped groove produced by wear of the sliding plate on the upper edge of the plate-like member. Since the structure is provided with a reference inclined edge serving as a reference, the wear caused on the sliding plate is caused by the operator comparing the inclined line of the stepped groove with the reference inclined edge. It is easy to know whether or not the replacement time has been reached.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1A is a diagram showing an overall configuration of a sliding plate wear measuring instrument 100 according to the present embodiment.
Specifically, the wear device 100 is a plate formed of a plastic transparent plate such as an acrylic plate and horizontally disposed so that the bottom portion 11 located at the lower end of the slide plate wear measurement device 100 is along the side surface length direction of the slide plate S. And a plurality of reference inclined lines 13 and 14 formed on the plate surface of the plate-like member 12.

These reference inclined lines 13 and 14 are inclined in the stepped groove 10 caused by wear of the sliding plate S in a state where the bottom portion 11 of the plate-like member 12 is horizontally arranged along the side surface length direction of the sliding plate S. By comparing with the line L, it becomes a criterion for judging whether or not the sliding plate S has reached the replacement time.
The inclination of each of the reference inclination lines 13 and 14 is a value of “l / d” (specifically, 0, 0.1, 0.2, 0...) Indicating the degree of inclination of the inclination line L of the stepped groove 10. 3) (which will be described later), in this example, the reference inclination line 13 when the value of “l / d” is “0.2 (= a1)” and , “0.3 (= a2)”, two examples of the reference inclination line 14 are shown.
In addition, the reference | standard inclination line 13 with a small inclination is an example when a soft material is used for the sliding board S, and the reference | standard inclination line 14 with a large inclination is an example when the hard material is used for the sliding board S. is there.

  Next, the reason why the value of “l / d” of the reference inclination line 13 is set to “0.2 (= a1)” will be described with reference to FIGS. In the following tests, evaluation was performed when a soft material made of a sintered body of carbon and copper was used as the sliding plate S.

As can be seen with reference to FIG. 2, “l” shown here represents the height distance between the upper surface of the sliding plate S and the deepest part of the stepped groove 10, and “d” represents the sliding plate S. Represents the distance between the inclination start position of the sliding plate S and the deepest portion of the stepped groove 10 along the length direction of the reference line, and “l / d” of the reference inclination line 13 based on such a positional relationship. Value is set.
2 indicates a trolley wire that has entered the stepped groove 10. Further, in FIG. 2, the inclined state on the other side of the two inclined surfaces is indicated by “l ′ / d ′”, but this is shown for easy understanding of the test results in FIG. Separated.

A sliding test for specifically determining the “l / d” will be described with reference to FIGS.
The trolley line M is installed in zigzags on the left and right sides so that the wear of the sliding plate S is equalized. Therefore, when the train travels, the trolley line M moves on the sliding plate S. At this time, if there is a step on the sliding plate S, the sliding plate S is restrained at that step, and the sliding time at that portion becomes longer than at other portions.
For this reason, in this sliding test, after using a sliding plate S having a stepped groove 10 as shown in FIG. 2, as shown in FIG. / D ", and the vertical axis represents the ratio of the sliding time when there is no step (T ₂ (s)) and the sliding time when there is a step (T ₁ (s)). Then, the tendency of wear generated in the sliding plate S was clarified.

As can be seen with reference to FIG. 3, when the “l / d” set as the shape parameter becomes about 0.2, the sliding time exceeds twice, so the wear of the sliding plate S It is thought that the amount increases about twice, and the step shape progresses rapidly.
In the above-described sliding test, the time required for the trolley wire M to move the distance d (mm) with the tension of the trolley wire M set to 9.8 kN and the pantograph push-up force set to 59 N. (When there is no step: T ₂ (s), when there is a step: T ₁ (s)) was measured.

For this reason, in the sliding plate wear measuring instrument 100 of the present embodiment, when a soft material is used for the sliding plate S, “l / d” is set to “0.2 (= a1)”. An inclined line 13 is used.
Thereby, in the said sliding plate wear measuring instrument 100, in the state which has arrange | positioned the bottom part 11 of the plate-shaped member 12 horizontally along the side length direction of the front side or the rear side of the sliding plate S, on the plate-shaped member 12. By comparing the reference inclined line 13 with the inclined line L of the stepped groove 10 caused by the wear of the sliding plate S, it can be used as a criterion for determining whether or not the sliding plate S has reached the replacement time.

Specifically, in the state where the bottom 11 of the plate-like member 12 is horizontally arranged along the side surface length direction of the slide plate S, the wear of the slide plate S at the angle of the reference inclination line 13 on the plate-like member 12. When the inclined line L of the stepped groove 10 generated by the above is not satisfied, the sliding plate S does not reach the replacement time, and it can be determined that there is no problem even if it is continuously used.
In addition, the bottom 11 of the plate member 12 is horizontally disposed so as to be along the length direction of the side surface of the sliding plate S, and is generated due to wear of the sliding plate S at the angle of the reference inclined line 13 on the plate member 12. When the inclined line L of the stepped groove 10 matches, it can be determined that the sliding plate S has reached the replacement time.
Further, the angle of the reference inclination line 13 on the plate-like member 12 is generated by the wear of the slide plate S in a state where the bottom portion 11 of the plate-like member 12 is horizontally arranged along the side surface length direction of the slide plate S. When the inclined line L of the stepped groove 10 is exceeded, it can be determined that the sliding plate S has passed the replacement time and needs to be replaced immediately.

Moreover, the abrasion which arises in the sliding board S by the sliding with the trolley line M advances as shown, for example in FIG.
Specifically, as shown in FIGS. 4A to 4D, as the wear of the stepped groove 10 progresses, the value indicating the inclination degree “l / d” of the inclination line L gradually increases. However, when this value reaches “0.2” shown in FIG. 4D, the inclined state of the upper surface of the stepped groove 10 is confirmed using the sliding plate wear measuring instrument 100 (FIG. 4). 4), it can be determined that the sliding plate S has reached the replacement time.
In addition, the reference inclination lines 13 and 14 corresponding to “0.2” or “0.3” indicating the inclination degree “l / d” at the replacement time of the above-described sliding plate S are the sliding plate S as described above. However, three or more reference inclination lines 13 and 14 may be provided so as to correspond to a large number of materials. Moreover, it is not limited to this, One reference | standard inclination line may be sufficient.

As described in detail above, in the sliding plate wear measuring instrument 100 shown in the first embodiment, the plate surface of the plate member 12 is compared with the inclined line L of the stepped groove 10 caused by the wear of the sliding plate S. Thus, since the structure is provided with the reference inclination lines 13 and 14 serving as a reference for determining whether or not the sliding plate S has reached the replacement time, the operator can set the inclination line L of the stepped groove 10 and the reference inclination. By comparing with the lines 13 and 14, it is possible to easily know whether or not the wear generated in the sliding plate S has reached the replacement time of the sliding plate S.
That is, in the present invention, when the stepped groove 10 is formed in the sliding plate S, the replacement timing of the sliding plate S can be easily determined with a simple configuration without using a complicated mechanism such as a sensor and a calculation means. The effect which becomes possible can be produced.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG.
The sliding plate wear measuring instrument 200 according to the second embodiment differs from the sliding plate wear measuring instrument 100 according to the first embodiment in that the reference slope line for determining the replacement time of the sliding plate S is a transparent plate. Rather than being drawn above, a reference inclined edge instead of the reference inclination line is provided at the upper edge of the transparent plate.
Specifically, the sliding plate wear measuring instrument 200 according to the second embodiment is formed of a plastic transparent plate such as an acrylic plate so that the bottom portion 21 positioned at the lower end thereof is along the side surface length direction of the sliding plate S. The plate-shaped member 22 to be arranged and the reference inclined edges 23 and 24 formed on the upper edge of the plate-shaped member 22 are formed as a set. With such a configuration, the plate-like member 22 is formed in a triangular shape.

The reference inclined edges 23 and 24 respectively formed on the plate-like member 22 are in a state where the bottom portion 21 of the plate-like member 22 is horizontally arranged along the front side or rear side length direction of the sliding plate S. By comparing with the inclined line L of the stepped groove 10 caused by the wear of the sliding plate S, it becomes a criterion for determining whether or not the sliding plate S has reached the replacement time.
The inclination of each of the reference inclined edges 23 and 24 is a value of “l / d” (specifically, 0, 0.1, 0.2, 0) indicating the degree of inclination of the inclined line L of the stepped groove 10. ...)), But in this example, the reference inclined edge 23 when the value of “l / d” is “0.2 (= a1)” and “ Two examples of the reference inclined edge 24 in the case of “0.3 (= a2)” are shown.
In addition, the reference | standard inclination edge part 23 with a small inclination is an example when a soft material is used for the sliding board S, and the reference | standard inclination edge part 24 with a large inclination is the case where a hard material is used for the sliding board S. This is an example, which is the same as the reference inclined lines 13 and 14 of the first embodiment.
In the sliding plate wear measuring instrument 200 of the second embodiment, the wear degree of the sliding plate S is not measured by the single sliding plate wear measuring instrument 100 as in the first embodiment, but the material of the sliding plate S is measured. Accordingly, one of the two plate members 22 is selected, and whether the replacement time of the sliding plate S has been reached based on the inclination of the reference inclined edge 23 or 24 of the selected plate member 22. A determination of no can be made.

As described above in detail, in the sliding plate wear measuring instrument 200 shown in the second embodiment, the upper edge of the plate-like member 22 is compared with the inclined line L of the stepped groove 10 caused by the wear of the sliding plate S. Thus, since the structure is provided with the reference inclined edges 23 and 24 serving as a reference for determining whether or not the sliding plate S has reached the replacement time, the operator can connect the inclined lines L of the stepped grooves 10 with the inclined lines L. By comparing with the reference inclined edges 23 and 24, it is possible to easily know whether or not the wear generated on the sliding plate S has reached the replacement time of the sliding plate S.
That is, in the sliding plate wear measuring instrument 200 shown in the second embodiment, when the stepped groove 10 is formed in the sliding plate S, a complicated structure such as a sensor and a calculation means is not used, and a simple configuration is used. There is an effect that it is possible to easily determine the replacement time of the sliding plate S.

  In the second embodiment, the slide plate wear measuring instrument 200 is constituted by the two plate-like members 22, but the present invention is not limited to this, and the slide plate wear measuring instrument is constituted by one or three or more plate-like members 22. 200 may be configured.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

  The present invention relates to a sliding plate wear measuring instrument that is applied to a pantograph that slides on a trolley line on a track and can easily check the wear level of the sliding plate.
