Description

Technical Field

[0001] The invention relates to the technical field of carbon slide plate measurement, in particular to a carbon slide plate thickness measuring instrument. Background Art

[0002] During the operation of the locomotive or EMU, the pantograph carbon slide plate is constantly wearing out due to the frequent sliding contact between the high-voltage cable and the high-speed sliding pantograph carbon slide plate. When the pantograph carbon slide plate is worn to a certain extent, it must be replaced, otherwise it will bring huge hidden dangers to the safety of track operation. Therefore, the wear of the pantograph carbon slide plate must be detected during the maintenance of relevant vehicles.

[0003] Currently, there are devices on the market for real-time detection of pantograph carbon plate wear, but their structure is complex and difficult to operate, and the wear time of the pantograph carbon plate does not need to be detected in real time. Therefore, the more common situation is to use manual measurement. After the vehicle stops running, the pantograph is lowered, and the pantograph and contact network are separated, and then the wear amount is manually detected. However, this method increases the labor cost of the operator and is prone to errors. Summary of the Invention

[0047] The housing assembly 5 is used to cover the frame assembly 1, the measuring assembly 4, the clamping assembly 2, the support assembly 3, and the data recording and analysis module 6. Specifically, the housing assembly 5 can be assembled from multiple plastic blocks to cover the entire exterior of the measuring instrument, providing protection.

[0048] The data recording and analysis module 6 includes a power supply 601, a main control board 602, a start / stop button 603 and a display 604 which are electrically connected to each other; the two laser ranging sensors 401 are electrically connected to the main control board 602, and the display 604 is arranged on the top outside of the housing component 5.

[0049] When the carbon skateboard thickness measuring instrument is working: the two rotating plates 201 are opened back to back at the same time through the manual drive part, and then the measuring instrument is placed on the carbon skateboard 12, and then the measuring instrument is pressed down with force so that the lateral rollers 203 and the encoder rollers 409 are tightly attached to the left and right sides of the carbon skateboard 12; the support component 3 lifts the entire measuring instrument under the action of the first tension spring 304 to ensure that the walking roller 202 and the top roller 302 are tightly attached to the lower surface of the carbon skateboard 12; then the measuring instrument is manually pushed to move on the carbon skateboard 12, and the laser ranging sensor 401 in the measuring component 4 measures the carbon skateboard 12. During the measurement process, the second tension spring 406 ensures that the measuring roller 407 can always stick to the lower surface of the carbon skateboard 12 during movement. When the carbon skateboard 12 is slightly deflected, the vertical position of the laser ranging sensor 401 will be adaptively adjusted for floating measurement to adapt to the slight deflection of the carbon skateboard 12 and ensure measurement accuracy.

Each rotating assembly 21 includes two rotating seats 211 and a second axle pin 212. The two rotating seats 211 are disposed on the fixed plate 102. The second axle pin 212 is fixed to the inner wall of the rotating plate 201 via a shaft sleeve. The two ends of the second axle pin 212 are respectively rotatably engaged with the two rotating seats 211. The rotating assembly 21 enables the rotating plate 201 to rotate relative to the fixed plate 102.

[0051] Specifically, if Figure 5As shown, as a specific setting method of the manual drive member, each of the manual drive members includes two drive components, and the two drive components are respectively located on the two outer sides of the mounting plate 101 in the width direction, and each drive component includes a fixed base 210 fixed to the upper end surface of the mounting plate 101, and a second connecting rod 213 in an inverted "T" shape is provided on the fixed base 210, and the top end of the second connecting rod 213 passes through the outer shell component 5 and is located on the outside. At the same time, a straight notch 8 is provided on the top of the outer shell component 5 for the top end of the second connecting rod 213 to slide back and forth. The middle portion of the bottom end of the second connecting rod 213 is rotatably connected to the fixed base 210. A circular hole 214 is provided on one side of the bottom end of the second connecting rod 213, and a third axle pin 215 is disposed within the circular hole 214. The third axle pin 215 is fixedly connected to the fixed base 210. A third connecting rod 216 is hingedly connected to the other side of the second connecting rod 213. The bottom of the third connecting rod 216 is hingedly connected to the outer wall of the rotating plate 201 via a connecting base 217. A handle 218 is fixedly disposed between the top ends of the two second connecting rods 213 in the two manual drive members. A spring mounting bracket 9 is provided on the inner side wall of each of the fixed plates 102, and each of the spring mounting brackets 9 is connected to a third tension spring 10. A second connecting plate 11 is provided on the inner wall of each of the rotating plates 201. The top of each second connecting plate 11 is located inside the fixed plate 102, and the other end of the third tension spring 10 is fixedly connected to the top of the second connecting plate 11. The third tension spring 10 enables the two rotating plates 201 to rotate and return to their original position without the action of external force.

[0052] The operating principle of the manual drive component is: when the handle 218 is manually moved, the second connecting rod 213 is driven to rotate relative to the fixed base 210, and then the third connecting rod 216 is driven to rotate. The rotating third connecting rod 216 drives the two rotating plates 201 to rotate, thereby opening the clamping assembly 2. After releasing the handle 218, under the elastic force of the third tension spring 10, the two rotating plates 201 rotate and reset, and the walking rollers 202 and the side rollers 203 on the rotating plates 201 are in close contact with the surface of the carbon slide plate 12.

[0053] Preferably, if Figure 9As shown, any of the rotating plates 201 is provided with an encoder 408 electrically connected to the main control board 602, and the output end of the encoder 408 is provided with an encoder roller 409 for contacting the side of the carbon slide 12. The encoder 408 is usually connected to the encoder roller 409 shaft and rotates as the encoder roller 409 rotates, thereby generating a series of pulse signals or digital signals. These signals can be received and decoded by the main control board 602 to determine the position and movement of the encoder roller 409. When an abnormality is found in the thickness of a certain part of the carbon slide 12, the main control board 602 marks the abnormal position through the encoder 408 and records it, which is convenient for the staff to directly detect it later and improve the efficiency of the thickness measurement of the carbon slide 12.

[0054] To sum up, the carbon skateboard thickness measuring instrument of the present invention has the advantages of small size, light weight, easy to carry, good repeatability of multiple measurements of the same object and good consistency of measurement results, which solves the problem of poor repeatability caused by personal techniques in manual measurement of carbon skateboard thickness.
