Description

Technical Field

[0001] The invention relates to the technical field of gearbox oil marks, in particular to a flexible oil mark device applied to a gearbox of a rail vehicle. Background Art

[0002] In order to improve the transmission efficiency of rail vehicles, a gearbox is usually installed inside. In order to ensure the transmission efficiency inside the gearbox, the amount of lubricating oil in the gearbox needs to be strictly controlled. In order to facilitate the observation of the amount of lubricating oil inside the gearbox, the gearbox of rail vehicles is usually equipped with an oil gauge device.

[0003] Traditional oil gauges are primarily categorized as sight glass and screw-in types. Window-type sight glass and related components are typically fastened to the gearbox housing via multiple bolts, making installation and removal cumbersome and prone to crushing. Screw-in oil gauges, on the other hand, have a relatively simple internal structure, but their components are poorly sealed, making them susceptible to oil leakage and clouding the sight glass, hindering lubricant level monitoring. Furthermore, both types suffer from limited observation range and accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional oil marking device has low safety and limited observation range and observation accuracy.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a flexible oil mark device applied to the gearbox of a rail vehicle, comprising a gearbox body, a lateral cover shell fixedly mounted on the outer opening of the gearbox body, an inner assembly groove provided on the inner wall of the lateral cover shell, a flexible scale bar slidably mounted inside the inner assembly groove, a top side adjusting wheel group for controlling the sliding of the flexible scale bar movably mounted on the top of the inner assembly groove, an observation window is provided on the lateral cover shell at the position corresponding to the flexible scale bar, engaging holes matching the top side adjusting wheel group are provided on both sides of the interior of the flexible scale bar, and a magnetically controlled lateral scraper plate controlled by the top side adjusting wheel group is elastically mounted on the inner top surface of the inner assembly groove.

[0006] The inner assembly groove is provided with an arc-shaped assembly groove for mounting the top side adjusting wheel set.

[0007] The top side adjusting wheel assembly comprises an upper electrically controlled driving wheel installed in the upper arc-shaped assembly groove and a lower driven wheel installed in the lower arc-shaped assembly groove.

[0008] The magnetically controlled side scraper includes a first elastic scraper installed on one side of the top surface of the inner assembly groove, a second elastic scraper installed on the other side of the top surface of the inner assembly groove, a first embedded electromagnet fixed on one side of the top surface of the inner assembly groove, and a second embedded electromagnet fixed on the other side of the top surface of the inner assembly groove.

[0009] Oil scraping plates are sleeved and fixed on the outer sides of the first elastic scraping plate and the second elastic scraping plate.

[0010] An embedded LED lamp controlled by a top-side adjusting wheel assembly is fixedly mounted on the inner wall of the inner assembly groove corresponding to the position of the observation window.

[0011] External meshing tooth heads matching with the meshing holes are staggered and fixed on the outer arc surfaces of the upper electrically controlled driving wheel and the lower driven wheel.

[0012] A level gauge for monitoring the horizontality of the gear box body is fixedly installed on the outer side of the gear box body.

[0013] A scale for conveniently recording the remaining amount of gear oil is provided on the outer side of the flexible ruler.

[0014] The gear box body and the lateral cover shell assembly surface are both provided with staggered sealing rubber rings.

[0015] The beneficial effects of the present invention are:

[0016] (1) A flexible oil level gauge device applied to a rail vehicle gearbox of the present invention drives a flexible ruler to slide and adjust inside an inner assembly groove by means of a top-side adjusting wheel set, and slides inside an observation window according to the sliding movement, thereby displaying the oil level more intuitively and making observation more accurate;

[0017] (2) By adopting a built-in structural layout, there will be no contact with the outside world during the observation process, reducing the impact of the external environment on the interior of the box and improving safety;

[0018] (3) By adopting the magnetically controlled side scraper design, the stability of the flexible scale can be guaranteed during idle time, while the isolation of the observation window can be guaranteed, ensuring the clarity and anti-interference performance of the observation window during long-term use;

[0019] (4) The top side adjustment wheel group and the magnetically controlled side scraper are adjusted by electronic control, which greatly reduces the difficulty of operation during oil level observation and makes the observation stability more excellent;

[0020] (5) The top side adjustment wheel group and the magnetically controlled side scraper are controlled in linkage, which not only makes the operation more convenient, but also ensures anti-interference during the observation process;

[0021] (6) The entire device adopts a split structure design, which is convenient for later maintenance and replacement;

[0022] (7) The flexible ruler design can be applied to various shapes of inner assembly grooves, greatly enhancing the applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The flexible oil mark device shown is applied to the gearbox of a rail vehicle, comprising a gearbox body 1, a lateral cover shell 2 fixedly mounted on the outer opening of the gearbox body 1, an inner assembly groove 3 provided on the inner wall of the lateral cover shell 2, a flexible scale bar 4 slidably mounted inside the inner assembly groove 3, a top side adjusting wheel group 5 for controlling the sliding of the flexible scale bar 4 movably mounted on the top of the inner assembly groove 3, an observation window 6 is provided on the lateral cover shell 2 at a position corresponding to the flexible scale bar 4, engaging holes 7 matching the top side adjusting wheel group 5 are provided on both sides of the flexible scale bar 4, and a magnetically controlled lateral scraper plate 8 controlled by the top side adjusting wheel group 5 is elastically mounted on the inner top surface of the inner assembly groove 3.

[0031] Working principle: When people need to measure the oil volume, they press the switch located on the side wall of the lateral cover 2. The switch has an electric control automatic reset energy supply, which starts when pressed and resets when released. There are two sets of control mechanisms installed in different positions. One is set on the inside and starts by pressing, and the other is set at the opening and starts by releasing, thereby controlling the top side adjusting wheel group 5 to start. Then the top side adjusting wheel group 5 drives the flexible ruler 4 to slide and adjust inside the inner assembly groove 3. The flexible ruler 4 drives the oil at the bottom upward, and the excess oil on the surface is scraped off by the magnetically controlled side scraper 8. People judge the oil level according to the amount of oil inside the meshing hole 7. After the observation is completed, people release the pressed switch. At this time, the top side adjusting wheel group 5 automatically resets to the initial position through the reset switch.

[0032] In order to facilitate assembly, an arc-shaped assembly groove 9 for mounting the top-side adjusting wheel set 5 is opened on the inner assembly groove 3.

[0033] The arc-shaped assembly groove 9 on the lower side and the gear box body 1 are provided with oil drain ports to facilitate the return of oil from the top.

[0034] In order to coordinate the guidance and driving, the top side adjusting wheel assembly 5 includes an upper electrically controlled driving wheel 51 installed in the upper arc-shaped assembly groove and a lower driven wheel 52 installed in the lower arc-shaped assembly groove.

[0035] The upper electrically controlled driving wheel 51 is composed of an embedded driving motor installed on the inner side of the upper arc-shaped assembly groove and a driving wheel axially fixed on the output shaft of the embedded driving motor. The embedded driving motor drives the driving wheel to control the flexible ruler 4 to slide and adjust.

[0036] In order to cooperate with magnetic control, the magnetically controlled side scraper 8 includes a first elastic scraper 81 installed on one side of the inner top surface of the inner assembly groove 3, a second elastic scraper 82 installed on the other side of the inner top surface of the inner assembly groove 3, a first embedded electromagnet 83 fixed on one side of the inner top surface of the inner assembly groove 3, and a second embedded electromagnet 84 fixed on the other side of the inner top surface of the inner assembly groove 3.

[0037] The first embedded electromagnet 83 is activated to control the flipping adjustment of the first elastic scraper 81 ; the second embedded electromagnet 84 is activated to control the flipping adjustment of the second elastic scraper 82 .

[0038] When the top-side adjusting wheel group 5 drives the flexible ruler 4 to slide toward the first elastic scraper plate 81, the first embedded electromagnet 83 will be activated to control the first elastic scraper plate 81 to separate from the surface of the flexible ruler 4; when the top-side adjusting wheel group 5 drives the flexible ruler 4 to slide toward the second elastic scraper plate 82, the second embedded electromagnet 84 will be activated to control the second elastic scraper plate 82 to separate from the surface of the flexible ruler 4.

[0039] It is shown that the first elastic scraper plate 81 and the second elastic scraper plate 82 are close to the surface of the flexible ruler 4 when idle.

[0040] In order to reduce the cost of later use, an oil scraper 85 is sleeved and fixed on the outer side of the first elastic scraper plate 81 and the second elastic scraper plate 82.

[0041] In order to facilitate observation, an embedded LED lamp 10 controlled by the top side adjusting wheel set 5 is fixedly mounted on the inner wall of the inner assembly groove 3 corresponding to the observation window 6 .

[0042] When the top-side adjusting wheel assembly 5 is started, the embedded LED lamp 10 will be started in conjunction, thereby improving the internal illumination and making it easier for people to observe in low-light conditions.

[0043] In order to avoid anti-slip and facilitate the discharge of oil from the meshing hole 7, external meshing tooth heads 11 that match the meshing hole 7 are staggered and fixed on the outer arc surfaces of the upper electronically controlled driving wheel 51 and the lower driven wheel 52.

[0044] In order to facilitate people to calculate the internal oil volume more accurately, a spirit level 12 for monitoring the horizontality of the gear box 1 is fixedly installed on the outer surface of the gear box 1.

[0045] The user first reads the value on the flexible ruler 4, then adjusts the oil level by adjusting the tilt angle of the level 12. When the flexible ruler 4 is at a low position, the relative coefficient is increased, thus obtaining a relatively accurate oil level. The coefficient value is engraved on the surface of the level 12 for easy operation.

[0046] In order to visually display the amount of oil, a scale 13 for conveniently recording the remaining amount of gear oil is provided on the outer surface of the flexible ruler 4.

[0047] When the flexible ruler 4 is fitted on the inner wall of the inner assembly groove 3 and slides upward, the oil inside will stick to the surface and the inside of the meshing hole 7. When passing through the magnetically controlled side scraper 8, the scraper 85 at its outer end will scrape off the oil stuck to the outer surface of the flexible rack 4. Since the fluidity of the oil inside the meshing hole 7 is relatively poor, a part of it will remain inside the meshing hole 7. People can determine the height of the actual oil level inside the meshing hole 7 by the amount of oil inside the meshing hole 7.

[0048] The scale is set to directly mark the number of remaining oil.

[0049] In order to improve the sealing and shock absorption performance on the assembly surface, the assembly surfaces of the gear box body 1 and the lateral cover shell 2 are both provided with staggered sealing rubber rings 14 .

[0050] The sealing rubber rings 14 on the assembly surfaces of the gear box body 1 and the lateral cover 2 are arranged in a staggered layout.

[0051] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
