Description

Technical Field

[0001] This utility model relates to a track reinforcement processing device, and more particularly to a track vehicle-type oil film removal device that can run on the track and remove track oil film as a pre-process for track reinforcement operations. Background Technology

[0002] Our company's patent application for a vehicle-type track strengthening device is documented in CN22148000U. A key application of track strengthening vehicles is the treatment of elevated rails at small-radius curves. When a rail vehicle passes through a small-radius curve at high speed, the elevated rails must withstand the enormous centrifugal force of the vehicle, resulting in particularly severe wear on this section of the track, making it a key area for strengthening by the track strengthening vehicle.

[0003] To protect the rails, an oiler is typically installed before the rails enter a small-radius curve. The lubricating oil produced by the oiler gets onto the wheels of the railcar and is carried onto the rails at the small-radius curve. Therefore, an oil film often forms at the wheel-rail junction of the high-radius curve. Moreover, the longer the rails are used, the thicker and more robust this oil film becomes. Figure 1 As shown, the oil film generally appears at the gauge angle of the track, which is also the key area for track reinforcement.

[0004] However, the presence of the oil film absorbs laser energy, thus weakening the track strengthening effect. Therefore, this oil film must be removed before strengthening operations. This invention relates to an adaptive track degreasing device for track strengthening vehicles suitable for this scenario. Utility Model Content

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] like Figure 1 As shown, a rail vehicle-type oil film removal device 100 has the following core components: a rail vehicle 101, an enhanced treatment device 104, a flexible connection mechanism 103, and a rail oil removal device 102.

[0043] The rail vehicle 101 serves as the platform for the entire device, and is optimized with navigation and power systems, enabling it to run smoothly on the track and accurately locate the work area. The enhancement treatment equipment 104 is installed on the vehicle, located behind the rail degreasing device 102, and is responsible for enhancing the track using laser or other technologies.

[0044] The flexible connection mechanism 103 connects the rail vehicle 101 and the rail degreasing device 102, giving the degreasing device a certain degree of flexibility and adaptability, enabling it to automatically adjust its position and attitude according to the unevenness and curve changes of the track, and ensuring optimal contact with the track surface.

[0045] The track degreasing device 102 is located in front of the reinforcement treatment equipment 104. Using a variety of tools, including flexible scraper blades, shovels, and steel brushes, it efficiently removes the oil film from the track surface, creating favorable conditions for subsequent track reinforcement operations. This layout and design of the device allows oil film removal and track reinforcement to be completed efficiently in a single operation, greatly improving the efficiency and quality of track maintenance and reinforcement work.

[0046] In actual operation, the rail vehicle 101 drives the entire device along the track. The track degreasing device 102 first cleans the oil film from the track surface. Through the adjustment of the flexible connecting mechanism 103, it closely adheres to the track surface and automatically adjusts the degreasing force according to the oil film thickness. After being treated by the degreasing device, the clean track surface then enters the working range of the strengthening treatment device 104. The strengthening device treats the track using laser or other technologies (this technical means is not the focus of this invention, and the method used does not affect the validity of this technical solution), improving the wear resistance and service life of the track. This adaptive degreasing and strengthening synergistic operation mode not only ensures the efficient realization of the strengthening effect but also enables the device to adapt to different types of tracks and complex working conditions, possessing broad application prospects and practical value.

[0047] Specifically, the flexible connection mechanism 103 includes a first connecting plate 10, a connecting rod 30, and a second connecting plate 20. The first connecting plate 10 is firmly installed on the rail vehicle 101, while the second connecting plate 20 is tightly connected to the rail degreasing device 102. The connecting rod 30 serves as an intermediate connector, with its two ends connected to the first connecting plate 10 and the second connecting plate 20 respectively via rotatable connections. This technology gives the rail degreasing device 102 flexible spatial adjustment capabilities, enabling it to automatically adapt to the curves and unevenness of the rail according to its shape and working conditions, thereby ensuring that the degreasing device always maintains optimal contact with the rail surface. Through the supporting and adjusting function of the flexible connection mechanism 103, the rail degreasing device 102 can efficiently complete the oil film cleaning task, creating favorable conditions for subsequent rail strengthening operations and ensuring the achievement of the strengthening effect.

[0048] More specifically, such as Figure 4 As shown, the lower side of the first connecting plate 10 is provided with two first connecting ears 11 for connecting to the first end of the connecting rod 30; the upper side of the second connecting plate 20 is provided with two second connecting ears 21 for connecting to the second end of the connecting rod 30.

[0049] A first spherical bearing 31 is installed at the first end of the connecting rod 30. This bearing is located between two first connecting ears 11. A first shaft passes through the two first connecting ears 11 and the first spherical bearing 31, thereby achieving a rotatable connection between the first connecting plate 10 and the connecting rod 30. Similarly, a second spherical bearing 32 is installed at the second end of the connecting rod 30. This bearing is located between two second connecting ears 21. A second shaft passes through the two second connecting ears 21 and the second spherical bearing 32, thereby achieving a rotatable connection between the second connecting plate 20 and the connecting rod 30.

[0050] The aforementioned technical means not only ensure the stability of the connection, but also, through the multi-directional rotation capability of the ball bearing, endow the track oil removal device 102 with flexible adjustment capability in three-dimensional space, enabling it to better adapt to the complex shape and unevenness of the track, thereby ensuring that the oil removal device always maintains close contact with the track surface and efficiently removes the oil film on the inner rounded corners and inclined surfaces of the track.

[0051] Preferably, the connecting rod 30 adopts a segmented telescopic structure, specifically including a fixed rod c3, a first telescopic rod c1, and a second telescopic rod c2. This allows the connecting rod 30 to adjust its length according to the actual conditions of the track, thereby better adapting to the unevenness and curve changes of the track.

[0052] The first spherical bearing 31 is installed at the outer end of the first telescopic rod c1 and is connected to the first connecting plate 10 through the first shaft, enabling multi-directional rotation; the second spherical bearing 32 is installed at the outer end of the second telescopic rod c2 and is connected to the second connecting plate 20 through the second shaft, also possessing multi-directional rotation capability.

[0053] To ensure the stability of the connecting rod 30 after adjustment, a first locking element is provided between the fixed rod c3 and the first telescopic rod c1, and a second locking element is provided between the fixed rod c3 and the second telescopic rod c2. Through the fixing action of the locking elements, the connecting rod 30 can remain stable after being adjusted to a suitable length, ensuring close contact between the track oil removal device 102 and the track surface and efficient oil removal during operation.

[0054] In addition, such as Figures 5 to 6 As shown, the track degreasing device 102 includes a frame 40 that can move along the track and an degreasing mechanism 50 disposed on the frame 40; the degreasing mechanism 50 is used to remove and clean the oil film on the track f.

[0055] Specifically, a rolling support device 41 is provided inside the frame 40, which acts on the top surface f1, the two side surfaces f2, and the bottom surface f3 of the track f. The rolling support device 41 consists of multiple rollers r, which contact the surface of the track f.

[0056] like Figures 5 to 9As shown, the oil removal mechanism 50 includes a flexible scraper blade 51, multiple scrapers 52, and a steel brush device 53; the flexible scraper blade 51 is used to remove the oil film from the track fillet f4; the multiple scrapers 52 are used to remove the oil film from the track slope f5; and the steel brush device 53 is used to further clean the oil film residue.

[0057] More specifically, the flexible scraper blade 51 is made of stainless steel sheet with a thickness of 0.3-0.6mm. This material selection not only ensures the blade's strength and durability but also gives it sufficient flexibility to adapt to the complex curved surface of the track fillet f4. The flexible scraper blade 51 is fan-shaped, which allows it to bend relatively during use, thus better conforming to the surface of the track fillet f4. The cutting edge 511 of the flexible scraper blade 51 is specially treated to ensure its sharpness and wear resistance, enabling it to efficiently scrape the oil film off the track surface.

[0058] The flexible oil scraper blade 51 is fixed and operated by two operating arms e. The front end of each operating arm e is equipped with gripping claws e1, which grasp the two sides of the flexible oil scraper blade 51, thereby moving the blade along the track to scrape away the oil film. The rear end of each operating arm e is connected to a mounting base via a connecting shaft, on which a first spring s1 is mounted. The elastic potential energy of the first spring s1 provides stable support for the flexible oil scraper blade 51, ensuring that the flexible oil scraper blade 51 always applies appropriate pressure to the track fillet f4, thus achieving efficient oil film removal. Simultaneously, the elastic characteristics of the spring also give the flexible oil scraper blade 51 a certain degree of floating and flexibility, allowing it to be fine-tuned according to the unevenness of the track surface, thereby ensuring sufficient contact with the track surface while avoiding damage to the blade itself or the track f due to excessive pressure.

[0059] The scraper 52 is another important component of the oil removal mechanism 50, used to remove the oil film on the inclined track surface f5. Preferably, each scraper 52 is mounted on the frame 40 via a connecting shaft b, on which a spring s2 is installed. The function of the spring s2 is to provide appropriate elastic support for the scraper 52, allowing it to be flexibly adjusted according to the shape of the inclined track surface f5 and the thickness of the oil film. This ensures close contact between the scraper 52 and the inclined track surface, thereby achieving efficient removal of the oil film.

[0060] Furthermore, the steel brush device 53 is the final cleaning step in the degreasing mechanism 50, used to further remove oil film residue from the track fillet f4 and slope f5. The steel brush device 53 consists of multiple wire brushes d, each including a handle d1 and a wire brush head d2. The wire brush head d2 is made of high-strength steel wire, possessing excellent wear resistance and elasticity, enabling it to penetrate deep into the tiny crevices of the track surface and thoroughly remove oil film residue. The layout design of the wire brush head d2 allows it to cover the track fillet f4 and slope f5, ensuring comprehensive cleaning of the track surface. Through the synergistic action of the flexible scraper blade 51, the scraper 52, and the steel brush device 53, the track degreasing device 102 can efficiently and thoroughly remove the oil film from the track surface, providing a good foundation for subsequent track strengthening operations.
