Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation measurement, in particular to a tool for measuring the wear height of a pantograph carbon slide. Background Art

[0002] The carbon slide plate of the EMU pantograph is an important high-voltage component. The EMU raises the pantograph and contacts the contact network to obtain power through the carbon slide plate. When the EMU is operating on the main line, the carbon slide plate will be worn to varying degrees due to friction with the contact network and uncontrollable environmental factors. If the carbon slide plate's wear limit is reached and is not replaced in time, it will cause the carbon slide plate to leak and lower the pantograph. Therefore, the height of the carbon slide plate is an important maintenance limit for special repairs and first-level repairs.

[0003] During the actual maintenance process, maintenance workers use steel rulers for measurement. Due to different measurement methods among operators, large errors occur, and there is a hidden danger of excessive discrepancies between measurement data and maintenance limits. If digital vernier calipers are used during operation, tools such as digital vernier calipers are too large, making it inconvenient to carry and measure on and off the roof, resulting in low work efficiency.

[0004] Therefore, in view of the shortcomings of the prior art, a tool for measuring the wear height of a pantograph carbon slide plate is provided. Utility Model Content

[0008] The caliper support is provided with a sliding groove slidably connected to the scale, the level is fixedly connected to the caliper support, the scale is provided with an opening for the locking piece to extend into, and the locking piece abuts against or separates from the caliper support.

[0009] As a further improvement of the technical solution of the present invention, the caliper holder is provided with a first measuring claw, and the scale is provided with a second measuring claw, and the first measuring claw and the second measuring claw are in contact with the carbon slide and the aluminum substrate to be measured respectively.

[0010] As a further improvement of the technical solution of the present invention, the caliper support is further provided with a contact surface that contacts the carbon slide plate to be measured, and the contact surface is away from the slide groove.

[0011] As a further improvement of the technical solution of the present invention, the scale line values ​​of the scale ruler are 0mm-80mm, and the standard spacing between the scale lines is 1mm.

[0024] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0025] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," and "right" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0026] Reference Figures 1 to 3 , a pantograph carbon slide wear height measuring tool, comprising a caliper holder 1, a scale 2, a spirit level 3 and a locking part;

[0027] The caliper support 1 is provided with a slide groove 11 that is slidably connected to the scale 2. The level 3 is fixedly connected to the caliper support 1. The scale 2 is provided with an opening 21 for a locking member to extend into. The locking member abuts or separates from the caliper support 1. Preferably, the level 3 is a miniature level 3 and is located 10 mm above the scale support.

[0028] To use the device, first place the measuring tool on the carbon slide and locate its lowest point, with the spirit level 3 in a completely horizontal position. Then, use the scale 2 and caliper holder 1 to clamp the lowest point of the carbon slide and the bottom edge of the aluminum base plate to measure the wear height of the carbon slide. Finally, tighten the locking member and read the value. This pantograph carbon slide wear height measurement tool features minimal measurement error. Preferably, the scale of the measuring tool matches the carbon slide height of the CRH6 EMU.

[0029] In one embodiment, the caliper holder 1 is provided with a first measuring jaw 12, and the scale 2 is provided with a second measuring jaw 22. The first measuring jaw 12 and the second measuring jaw 22 respectively contact the lowest point of the carbon slide to be measured and the lower edge of the aluminum substrate. The carbon slide is positioned above the aluminum substrate. During measurement, the heights of both are measured simultaneously. The height of the carbon slide is the measured value minus the height of the aluminum substrate. The worn height of the carbon slide is the original height of the carbon slide minus the measured height of the carbon slide.

[0030] In one embodiment, in order to find the lowest measuring point of the carbon slide and ensure the accuracy of the value, the caliper holder 1 is further provided with a contact surface that contacts the carbon slide to be measured, and the contact surface faces away from the slide groove 11 .

[0031] In one embodiment, the scale lines 23 of the scale ruler 2 have values ​​ranging from 0 mm to 80 mm, and the spacing between the scale lines 23 is 1 mm. The scale lines 23 are fluorescent white, which is preferably convenient for clear reading even in a dark environment.

[0032] In one embodiment, opening 21 is a threaded hole, and the locking member is a fixed knob, which is threadedly connected to the threaded hole. After measuring a value, the operator can tighten the fixed knob clockwise to fix the value of scale 2, preventing the value from being disturbed during reading and causing changes. After the measurement is completed, the fixed knob can be loosened counterclockwise to reset scale 2. Similarly, counterclockwise loosening the fixed knob is used to loosen the fixed knob.

[0033] In one embodiment, the caliper holder 1 is 950 mm long, 350 mm wide, and 3 mm thick, wherein the depth of the middle slide groove 11 is 1 mm for the extension and retraction of the ruler 2 , and its contact surface can be customized with a LOGO.
