Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0033] When checking the oil level in a gearbox, the oil level will appear significantly different depending on the individual's height and the angle between their line of sight and the oil surface. In such cases, it is necessary to use tools to mark the oil level to avoid inspection errors caused by incorrect viewing angles and to ensure the accuracy of the marked oil level lines.
[0034] like Figure 1 As shown, the oil level gauges on the gear oil tanks of some EMU models are not all vertically mounted, but rather angled. However, when checking the oil level, the oil surface is horizontal, resulting in an angle between the gauge and the oil surface. Furthermore, the gauges are fixed with bolts, which create protrusions around them. In this situation, marking lines on the gauge is difficult due to the limited space, making it hard to ensure the marked lines are horizontal, and may even lead to discrepancies between the marked lines and the actual oil level. Using tools for assistance is problematic because the gauge itself is angled, making it difficult to position the tool correctly; and the bolts and other components near the gauge also obstruct movement of the tool within the gauge's range.
[0035] Based on this, such as Figure 2 , 7As shown, the utility model embodiment provides a kind of EMU gear box oil level mirror scribing device, including the box body 1 for positioning and the scribing rod 2 for moving with oil surface position. By the box body 1, the scribing device is positioned on oil level mirror, then scribing rod 2 is moved along the setting direction of oil level mirror, so that the front end of scribing rod 2 reaches oil surface, and is flush with the oil surface, then scribing is carried out along the front end of scribing rod 2, and the inspection scribing of gear box oil surface is completed. By the position where scribing rod 2 is located, field operating personnel can accurately and quickly scribe standard and normative gear box oil level position mark line, solve the problem that gear box oil level mark line is not accurate, not normative, not standard, operating time is long and efficiency is low, observation each gear box oil level is not accurate in overhaul process due to the factors such as that field operating personnel are not of the same height, observation gear box oil level sight in oil level mirror is not unified, there is no targeted professional scribing tool in field, etc. In the dynamic regulation and control operation of gear box oil circuit reconstruction-free vehicle group summer mode oil extraction and winter mode oil supplement, as the special device of EMU gear box oil level mirror scribing, it has obvious technical pertinence.
[0036] Since the overall of EMU gear box oil level mirror is rectangular table body, and the strip-shaped glass sight glass arranged in the center thereof plays a detecting role, the glass sight glass is arranged in a sunken manner relative to the table surface of oil level mirror.
[0037] The bottom rear end of the box body 1 is provided with a first positioning plate 11, and the first positioning plate 11 is a short vertical plate arranged vertically downward. The bottom of the box body 1 is also provided with a second positioning plate 12, and the second positioning plate 12 is a short plate arranged vertically downward, and the shape thereof is the same as that of the bottom of the glass sight glass. The distance between the first positioning plate 11 and the second positioning plate 12 is the same as the distance from the bottom edge of the table body of the oil level mirror to the bottom of the glass sight glass, and the bottom surface of the box body 1 is a magnet. In use, the first positioning plate 11 is arranged at the bottom edge of the table body of the oil level mirror, and the second positioning plate 12 is arranged at the bottom of the glass sight glass. Since the bottom of the glass sight glass is a curved surface, the first positioning plate 11 and the second positioning plate 12 are used in cooperation to directly position the entire box body 1 on the oil level mirror, and then the magnet on the bottom surface thereof is used to provide adhesion force, so that the positioning of the box body 1 is realized.
[0038] The box body 1 is also provided with an adjusting groove 13, and the adjusting groove 13 penetrates the box body 1 at the head and tail, and the scribing rod 2 is arranged in the adjusting groove 13 and slides along the adjusting groove 13 to adjust the position of the front end thereof.
[0039] The box body 1 is also provided with a positioning groove 14, and the positioning groove 14 extends away from the first positioning plate 11 from the second positioning plate 12 until the edge of the box body 1. After the box body 1 is positioned on the oil level mirror, the oil level condition in the glass sight glass can also be observed through the positioning groove 14.
[0040] The scribing rod 2 comprises a pull rod 21 arranged in the adjusting groove 13 and a scribing head 22 arranged at the front end of the pull rod 21. A long slot is formed in the center of the pull rod 21 along the length direction of the pull rod 21 as an observation slot 23, which avoids the observation slot 23 from blocking the glass sight mirror. In the scribing process, the oil surface position in the glass sight mirror is observed through the observation slot 23, and the oil surface position is confirmed at any time to avoid misjudgment.
[0041] In the scribing process, in order to make the scribing mark more obvious, a thicker marker is used, and the handwriting is different according to different scribing angles. If the handwriting is too thick, the oil surface position mark will not be clear. As a further preferred, in order to unify the scribing width, a scribing slot 24 is arranged at the head of the scribing head 22. The scribing slot 24 is parallel to the inclined surface at the front end of the scribing head 22, and the width of the scribing slot 24 remains unchanged. In use, the scribing slot 24 is aligned with the oil surface, and the oil level is marked on the two side bodies of the glass sight mirror by using the marker.
[0042] In an embodiment of the present application, in order to prevent the separation of the box body 1 and the scribing rod 2 during carrying and to avoid the loss of one of the two, a limiting column 15 (not shown in the figure) is further arranged at the rear end of the adjusting groove 13. The limiting column 15 is further arranged in the observation slot 23 of the scribing rod 2, and the diameter of the limiting column 15 is smaller than the width of the observation slot 23, so as to prevent the scribing rod 2 from being pulled out of the adjusting groove 13.
[0043] A sliding sleeve 3 is further arranged between the two side surfaces of the pull rod 21 and the box body 1. The sliding sleeve 3 comprises a positioning sleeve 31 and a ball 32 arranged in the positioning sleeve 31. The surface of the ball 32 is in contact with the side surface of the pull rod 21. The pull rod 21 is more smooth during the pulling process in the adjusting groove 13, and jamming is avoided.
[0044] As a further preferred, a scale line 25 can be further arranged along the side surface of the pull rod 21. When temporarily needed, some sizes are measured through the scale line 25, and the multifunctionality of the scribing device is realized.
[0045] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
