Description

Technical Field

[0001] This utility model belongs to the field of carbon slide plate wear detection, and specifically relates to a carbon slide plate wear detection device. Background Technology

[0002] As a core conductive component of the pantograph system in rail transit vehicles, the carbon sliding contact plate transmits electrical energy through dynamic sliding contact with the overhead contact line, making it a crucial link in ensuring the train's power supply. During long-term operation, the carbon sliding contact plate inevitably experiences wear due to factors such as high-speed mechanical friction with the overhead contact line, arc erosion caused by instantaneous separation, environmental erosion from sand, rain, and snow, and localized stress concentration caused by improper installation and maintenance. This wear manifests as thinning of the surface, localized dents, edge defects, or uneven wear.

[0003] To ensure train operation safety, the wear condition of carbon sliding plates needs to be inspected regularly. Among them, wear depth, remaining thickness and surface defect size are the core indicators. For minor wear, it can be filled or polished with special conductive repair agent. However, before repair, it is necessary to accurately measure parameters such as the depth and area of ​​the wear area to determine the repair scope and process. At present, on-site inspection of carbon sliding plate wear is still mainly based on traditional manual inspection. Especially in repair work, tools such as vernier calipers and plug gauges are relied upon to complete the measurement of key dimensions.

[0004] In practice, inspectors must climb onto the train roof and select multiple inspection points, typically 5-8, on the carbon sliding plate surface. This method is cumbersome, requiring sequential inspection of each part of the carbon sliding plate, and each measurement necessitates repeated tightening and loosening of calipers, resulting in low efficiency and difficulty in meeting the needs of short-term train maintenance shutdowns. Furthermore, it is labor-intensive, requiring inspectors to maintain a bent-over or squatting posture for extended periods on the roof, and the limited space restricts operational flexibility, easily leading to fatigue. Although automated inspection equipment, such as laser scanning devices, exists, it is primarily suitable for batch inspection after vehicles enter the depot. This equipment is bulky, costly, and requires specific inspection stations, making it difficult to apply flexibly at the carbon sliding plate repair site (such as temporary maintenance points).

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a detection mechanism located at the front end of a carbon slide plate. The moving outer shell allows the upper and lower rollers to roll on the upper and lower sides of the slide plate. When the rollers reach the carbon slide plate of normal thickness, the distance between them is normal, and the sliding seat slides to the unmarked area in the middle of the groove. When the rollers reach the worn carbon slide plate, the distance between them decreases, and the sliding seat moves within the groove. The position of the sliding seat at the mark indicates the wear condition of the carbon slide plate. By sliding the detection device at the outer end of the carbon slide plate, the wear condition at various points can be determined, eliminating the need for repeated measurements at different points on the outer end and thus improving the detection efficiency.

[0018] This invention, by setting up a disassembly and assembly unit, allows the round rod to rotate when the pressure block is rotated, and the threaded part at its front end rotates within the threaded groove inside the fixed seat and sliding seat. This allows the round rod and pressure block to move forward until the round rod leaves the inner side of the threaded groove. Then, the upper or lower rotating roller can be pulled forward and removed from the front end of the sliding seat or fixed seat. This allows the upper and lower rotating rollers to be quickly disassembled and assembled in the detection device, so that when detection errors occur on the outer side of the upper and lower rotating rollers due to wear, the upper and lower rotating rollers can be disassembled and replaced.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a carbon slide plate wear detection device, the structural schematic diagram of which is shown below. Figures 1 to 3 As shown, the device includes a carbon slide plate 1, with a housing 2 at its front end. A through groove is formed on the upper part of the front end of the housing 2, and scale lines are symmetrically formed on the upper and lower ends of the right side of the through groove. A handle 3 is welded to the lower front end of the housing 2. Detection mechanisms are provided at both the inner and outer ends of the housing 2. Each detection mechanism includes a vertical rod 401 fixedly connected to the front end of the inner side of the housing 2. A fixed seat 402 is fixedly connected to the lower outer end of the vertical rod 401, and a sliding seat 403 is connected to the upper outer end of the vertical rod 401. A through-hole is formed in the middle of the sliding seat 403. The outer side of the vertical rod 401 is slidably connected to the inner side of the sliding hole. The lower end of a spring 404 is fixedly connected to the upper side of the sliding seat 403, and the outer front end of the sliding seat 403 is slidably connected to the inner side of the through groove. When the spring 404 springs, it can drive the sliding seat 403 to slide along the outer side of the vertical rod 401 and the inner side of the through groove, thereby limiting the movement of the sliding seat 403.

[0027] Among them, a spring 404 is fixedly connected to the top of the inner side of the outer shell 2 at the outer end of the vertical rod 401, an upper roller 405 is connected to the rear end of the sliding seat 403, a lower roller 406 is connected to the rear end of the fixed seat 402, the outer side of the upper roller 405 is in rolling connection with the upper side of the carbon slide plate 1, and the outer side of the lower roller 406 is in rolling connection with the lower side of the carbon slide plate 1. By moving the outer shell 2 at the front end of the carbon slide plate 1, the upper roller 405 and the lower roller 406 roll on the upper and lower sides of the carbon slide plate 1. When the upper roller 405 and the lower roller 406 roll to the carbon slide plate 1 of normal thickness, the distance between the upper roller 405 and the lower roller 406 is the normal distance, and the sliding seat 403 slides to the unmarked mark in the middle of the inner side of the groove. When the upper roller 405 and the lower roller 406 roll to the carbon slide plate 1 with wear, the distance between the upper roller 405 and the lower roller 406 will decrease. At this time, the sliding seat 403 will move in the groove. At this time, the wear condition of the carbon slide plate 1 can be known by the position of the sliding seat 403 at the mark. Then, by sliding the detection device at the outer end of the carbon slide plate 1, the wear condition of various parts of the carbon slide plate 1 can be known without repeating the measurement work at different parts of the outer end of the carbon slide plate 1, thereby improving the detection efficiency of the carbon slide plate 1.

[0028] Cooperate Figure 4 As shown, the upper roller 405 and the lower roller 406 are internally equipped with disassembly and assembly units. Each disassembly and assembly unit includes a round rod 501 connected to the rear ends of the fixed seat 402 and the sliding seat 403. A threaded groove is formed at the middle of the rear ends of the fixed seat 402 and the sliding seat 403. An external thread is formed on the outer side of the front end of the round rod 501, and the outer side of the front end of the round rod 501 is threaded to the inner side of the threaded groove. A pressure block 502 is fixedly connected to the rear end of the round rod 501. A bearing 503 is internally connected to the upper roller 405 and the lower roller 406, and an inner round tube 504 is fixedly connected to the inner side of the bearing 503. A through-hole is provided in the middle of the upper roller 405 and the lower roller 406. The bearing 503 is installed at the left and right ends of the inner side of the hole. The outer side of the round rod 501 is slidably connected to the inner side of the inner tube 504. The front side of the pressure block 502 abuts against the rear side of the inner tube 504. The front side of the inner tube 504 abuts against the rear side of the fixed seat 402 or the sliding seat 403. By rotating the pressure block 502, the round rod 501 rotates. At the same time, the threaded part at its front end rotates in the threaded groove inside the fixed seat 402 and the sliding seat 403. This allows the round rod 501 and the pressure block 502 to move forward until the round rod 501 leaves the inner side of the threaded groove. Then, the upper roller 405 or the lower roller 406 can be pulled forward and removed from the front end of the sliding seat 403 or the fixed seat 402. This allows the upper roller 405 and the lower roller 406 to be quickly installed and removed from the detection device. This facilitates the disassembly and replacement of the upper roller 405 and the lower roller 406 when detection errors occur due to wear on the outer side of the upper roller 405 and the lower roller 406.

[0029] Working principle: When detecting the wear of carbon slide plate 1, first pull the upper roller 405 up to move it away from the lower roller 406, then move the outer shell 2 to the front left end of carbon slide plate 1. Then release the upper roller 405, and the spring 404 rebounds to push the sliding seat 403, pushing the upper roller 405 to the upper side of carbon slide plate 1. At this time, the upper roller 405 and the lower roller 406 are located on the upper and lower sides of carbon slide plate 1, respectively. Then, hold the handle 3 and move the outer shell 2 to the right along the outer end of carbon slide plate 1, so that the upper roller 405 and the lower roller 406 roll at the outer end of carbon slide plate 1. When the sliding seat 403 moves to the scale line inside the through groove inside the outer shell 2, it indicates that carbon slide plate 1 has wear, and it is recorded for subsequent repair. After sliding to the rightmost end, the wear of carbon slide plate 1 can be understood according to the movement of the sliding seat 403.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
