Description

  The present invention relates to a sliding plate wear measuring apparatus and a measuring method which are applied to a pantograph that slides on a trolley line 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, there is a risk of developing into trouble.

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 second member is provided with an indicating member whose upper end is rotatably connected to the second member. When the second member is aligned with the inclined line on the upper surface of the stepped groove caused by wear of the sliding plate, the lower end of the indicating member corresponds to the inclined line of the second member. It is installed to point to a predetermined location in the length direction.
If a notation such as a scale or a mark corresponding to the inclination degree of the second member is attached to a predetermined portion of the first member, the wear generated on the sliding plate by referring to the notation by the operator. However, it is possible to easily know whether or not it is time to replace the sliding plate.
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.

  In the present invention, a notation such as a scale or a mark indicated by the indicating member is provided at a predetermined position in the length direction of the first member.

  And according to the above invention, since a notation such as a scale or a mark indicated by the indicating member is provided at a predetermined position in the length direction of the first member, the operator refers to the notation, It can be easily known whether or not the wear generated on the sliding plate has reached the replacement time of the sliding plate.

  In the present invention, the indicating member is a lower weight provided so as to be rotatable about a rotation shaft at an upper end connected to the second member and arranged in a vertical direction by its own weight. To do.

  And according to the said invention, since the indication member is rotatably provided centering on the rotating shaft of the upper end connected to the 2nd member, it is comprised by the downward weight arrange | positioned by the dead weight in the perpendicular direction. Corresponding to the degree of inclination of the second member, the lower portion of the indicating member can point to a predetermined position in the length direction of the first member. Then, if a notation such as a scale or a mark corresponding to the degree of inclination of the second member is attached at a predetermined position of the first member, the operator refers to the notation, and is generated on the sliding plate. It can be easily known whether or not the wear has reached the replacement time of the sliding plate.

  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. .

(A) is a figure which shows the curve-shaped normal wear which arose in the sliding board, and the stepped abrasion which a (B) produced in the sliding board.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1A is a diagram showing the overall configuration of the sliding plate wear measuring apparatus 100 according to the present embodiment, which is mainly composed of a first linear member 11, a second linear member 12, and an indicating member 13. The

The first linear member 11 is horizontally arranged along the length direction of the sliding plate S in a state where it is in contact with the side surface of the sliding plate S.
The second linear member 12 is connected to the first linear member 11 so as to be rotatable in the direction of the arrow a via the rotation shaft 14 located at the base end portion. Rotate in a plane perpendicular to the trolley line, as shown in FIG.
Then, the second linear member 12 is inclined in the upper surface of the stepped groove 10 caused by wear of the sliding plate S by the rotation in the direction of the arrow a with respect to the first linear member 11 via the rotation shaft 14 (reference symbol L). Is aligned).
In FIG. 1B, the second linear member indicated by reference numeral 12 indicates an inclined state when the sliding plate S reaches the replacement time, and the second linear member indicated by reference numeral 12 (12A) The inclined state when the sliding plate S does not reach the replacement time is shown, and the second linear member denoted by reference numeral 12 (12B) shows the inclined state when the sliding plate S has passed the replacement time.

The indicating member 13 is a lower weight whose upper end is rotatably connected via a rotating shaft 15 provided at the tip of the second linear member 12, and is arranged in the vertical direction by its own weight.
The lower end portion of the indicating member 13 is a pointer portion 16 that points to a predetermined position in the length direction of the first linear member 11, and the first linear member 11 pointed to by the pointer portion 16 has a scale 17. Is provided.

The scale 17 is given a value “l / d” indicating the degree of inclination of the inclined line L of the stepped groove 10.
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 first linear member 11 in the length direction. In a predetermined place, a value of “l / d” (specifically, 0, 0.1, 0.2, 0.3...) Indicating the degree of inclination of the inclined line L of the stepped groove 10 is provided. It is attached.
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 determining “l / d” which is the value of the scale 17 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.

If the action of the sliding plate wear measuring apparatus 100 according to the present embodiment is described together with the wear measuring method, first, the first linear member 11 is horizontal along the side surface and the length direction of the sliding plate S as shown in FIG. After the arrangement, the second linear member 12 is aligned along the inclined line L on the upper surface of the stepped groove 10.
In this state, as indicated by a solid line in FIG. 1 (B), the pointer portion 16 positioned at the lower end of the indicating member 13 is formed on the scale 17 of the first linear member 11. When “0.2” indicating the inclination degree “l / d” of the inclination line L is indicated, it can be determined that the sliding plate S has reached the replacement time.
Further, in this state, as indicated by reference numeral 12 (12A) in FIG. 1 (B), the pointer portion 16 of the indicating member 13 is provided on the scale 17 of the first linear member 11, and the stepped groove 10 is If it is less than “0.2” indicating the degree of inclination “l / d” of the inclination line L, it can be determined that there is no problem even if the sliding plate S does not reach the replacement time and continues to be used as it is.
Further, as indicated by reference numeral 12 (12B) in FIG. 1B, the pointer portion 16 of the indicating member 13 is attached to the scale line 17 of the first linear member 11 on the inclined line L of the stepped groove 10. When it exceeds “0.2” indicating the degree of inclination “l / d”, it can be determined that the sliding plate S has passed the replacement time and needs to be replaced immediately.

In the sliding plate wear measuring apparatus 100 shown in the present embodiment, the pointer portion 16 positioned at the lower end of the indicating member 13 in a state where the second linear member 12 is aligned along the inclined line L on the upper surface of the stepped groove 10. Is changed depending on whether or not “0.2” indicating the degree of inclination “l / d” of the inclined line L of the stepped groove 10 attached to the scale 17 of the first linear member 11 is indicated. It is possible to determine whether or not the time has been reached.
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.

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 above-mentioned sliding plate wear measuring device 100 (FIG. 4). 4), it can be determined that the sliding plate S has reached the replacement time.
It should be noted that the value “0.2” indicating the degree of inclination “l / d” at the time of replacement of the sliding plate S naturally varies depending on the material of the sliding plate S. For example, a standard value of “0.2” is used in the case of a commonly used sintered body of carbon and copper, and a comparatively large standard value of “0.3” is used when a harder material is used. The reference value “l / d” that is the replacement timing of the sliding plate S may be appropriately changed according to the material of the sliding plate S.

  As described above in detail, in the sliding plate wear measuring apparatus 100 shown in the present embodiment, the first linear member 11 disposed on the side surface of the sliding plate S and the first linear member 11 are rotatably connected to the first linear member 11. A second linear member 12 that is aligned with an inclined line L on the upper surface generated by the wear of the sliding plate S, and a pointer portion 16 that is rotatably connected to the second linear member 12 and positioned at the lower end thereof is a first straight line. And an indicating member 13 indicating a predetermined position in the length direction of the member 11.

And if the measuring method using such a sliding plate abrasion measuring apparatus 100 is demonstrated with the effect | action, after the 1st linear member 11 is horizontally arranged along the side surface and the length direction of the sliding plate S, a stepped groove The second linear member 12 is aligned along the inclined line L on the upper surface of the upper surface 10.
In this state, the pointer portion 16 located at the lower end of the indicating member 13 indicates the degree of inclination “l / d” of the inclined line L of the stepped groove 10 attached to the scale 17 of the first linear member 11. When “0.2” is indicated (or when a value of 0.2 or more is indicated), it can be determined that the sliding plate S has reached the replacement time.
That is, in the sliding plate wear measuring apparatus 100, when the stepped groove 10 is formed in the sliding plate S, the sliding plate S can be easily formed with a simple configuration without using a complicated mechanism such as a sensor and a calculation means. There is an effect that it is possible to determine the replacement time.

In the above-described embodiment, the pointer portion 16 positioned at the lower end of the indicating member 13 has a scale 17 (specifically, 0, 0.1, 0.2, 0.3 · ... and a scale 17).
However, the present invention is not limited to such a notation, and a mark as a mark is attached only to “0.2” indicating the replacement determination timing of the sliding plate S in the inclination degree “l / d” of the inclination line L, It may be determined whether or not the replacement time of the sliding plate S has been reached, based on whether or not the pointer portion 16 located at the lower end of the pointing member 13 points to this mark.

  Moreover, in the said embodiment, although the 2nd linear member 12 is piled up and arrange | positioned on the upper surface of the 1st linear member 11, and the indication member 13 is arranged on the upper surface of the 2nd linear member 12, it is limited to this. Instead, the second linear member 12 and the indicating member 13 may be disposed on the same side of the first linear member 11. At this time, in order to minimize the interference between the second linear member 12 and the indicating member 13, the thicknesses of the respective members are reduced and the positions of the rotary shafts 14 and 15 are prevented from protruding when folded. Is set to be shifted along the width direction of the first linear member 11 (for example, in FIG. 1, the rotation shaft 14 is below the right end portion of the first linear member 11, and the rotation shaft 15 is the left end portion of the first linear member 11. It is better to install on the upper side. In addition, the linear member is not limited to a straight line or a line shape, and may be a plate shape or a rod shape as long as the shape is suitable for the operation of positioning along the side surface of the sliding plate or aligning along the upper surface of the sliding plate. There may be.

  Moreover, in the said embodiment, although the scale 17 was provided in the predetermined location of the 1st linear member 11, it is not limited to this, You may provide in the instruction | indication member 13 side. At that time, a mark is provided at the intersection of the first linear member 11 where the indicating member 13 intersects, and this mark indicates the scale provided on the indicating member 13, whereby the inclination degree of the inclined line L of the stepped groove 10 is “ It is also possible to know “l / d”.

  Further, in the above embodiment, the indication member 13 is vertical due to its own weight, but the present invention is not limited to this, and when measuring the inclination state of the stepped groove 10, The indication member 13 may be rotated so as to be vertical.
