[0002] Steel rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock, bear the enormous pressure from the wheels, and transmit this pressure to the sleepers. Steel rails must provide a continuous, smooth, and least resistance-prone rolling surface for the wheels. In electrified railways or automatic block signaling sections, steel rails can also serve as track circuits. The cross-sectional shape of steel rails adopts an I-beam shape with optimal bending resistance, consisting of three parts: the rail head, the rail web, and the rail base. To better withstand forces from various directions and ensure necessary strength, steel rails should have sufficient height, with adequate area and height at the head and base, and the web and base should not be too thin. Regular maintenance is required during daily use to ensure continued serviceability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a maintenance equipment for railway rails, including a portable bracket assembly 1, a lifting sponge wiping assembly 2 installed on the front side of the portable bracket assembly 1, an oil tank assembly 3 installed on the top of the front side of the portable bracket assembly 1, a drying assembly 5 installed on the top of the oil tank assembly 3, and a lifting brake assembly 4 installed around the bottom of the oil tank assembly 3.

[0026] The lifting sponge assembly 2 includes a limiting lifting groove 201, a return spring 202 is installed inside the limiting lifting groove 201, and the limiting lifting groove 201 is connected to the middle of the support base 101.

[0027] By installing a lifting sponge wiping assembly 2 on the device, when using this device, the lifting brake assembly 4 can be used to push the lubricating oil against the surface of the track through the lifting sponge wiping assembly 2. During the movement, the track can be lubricated, thus achieving a better maintenance effect.

[0028] The portable bracket assembly 1 includes a support base 101, with casters 102 mounted on the bottom of the support base 101 and a push rod 103 mounted on the top of the support base 101. A mounting bracket 104 is mounted on the front side of the push rod 103. The lifting sponge assembly 2 is mounted in the middle of the support base 101. Then, the push rod 103 and the casters 102 at the bottom are used for convenient and labor-saving movement. At the same time, the oil tank assembly 3 is mounted on the mounting bracket 104 to complete the basic installation work.

[0029] A limit lifting plate 203 is installed on the top of the return spring 202. A limit groove 204 is opened in the middle of the limit lifting plate 203. A sponge 205 is installed at the bottom of the limit groove 204.

[0030] The oil reservoir assembly 3 includes an oil reservoir 301. An oil inlet 302 is installed in the middle of the outer side of the oil reservoir 301, and a telescopic spring tube 303 is installed at the bottom of the oil reservoir 301. The oil reservoir 301 is connected to the outer side of the mounting bracket 104. A lifting port 304 is installed at the bottom of the telescopic spring tube 303, and an oil pump head 305 is installed inside the lifting port 304. The oil pump head 305 is connected to the oil reservoir 301 via an oil pipe. During movement, before movement, lubricating oil is first injected into the oil reservoir 301 through the oil inlet 302. Then, the lifting brake assembly 4 opens the lifting port 304... The downward extension is achieved by stretching the telescopic spring tube 303 until it reaches the inside of the limiting groove 204. This allows the oil pump head 305 to inject lubricating oil into the sponge 205. As the sponge continues downward, the internal return spring 202 is squeezed to make it continue downward, allowing it to contact tracks at different heights. This process, through sponge friction during movement, not only lubricates and maintains the track but also removes dirt, achieving efficient maintenance.

[0031] The lifting and braking assembly 4 includes a movable hinge 401, which is connected to the outer wall of the oil reservoir 301. A pneumatic telescopic pump 402 is installed on the outside of the movable hinge 401. A telescopic rod 403 is installed at the bottom of the pneumatic telescopic pump 402. A movable hinge 404 is installed at the end of the telescopic rod 403.

[0032] The air drying assembly 5 includes a fan box 501 and an exhaust pump 504. The fan box 501 has a diffuser 502 on one side and an exhaust 503 at the bottom. The fan box 501 is connected to the outside of the push rod 103. The exhaust pump 504 is installed on the top of the fan box 501, and its end is installed on the top of the dust collection box 505. The dust collection box 505 is connected to the top of the oil storage tank 301 via a base plate 506. The air drying assembly 5 installed on the rear side can cure the curing effect of the front side. During the curing process, the bottom exhaust 503 of the fan box 501 first blows air through the corresponding track at the bottom to dry it. At the same time, the exhaust pump 504 inside the fan box absorbs the impurities inside the dust collection box 505. This completes the overall workflow.

[0033] In use, first, install the lifting sponge wiping assembly 2 on the bottom front side of the portable bracket assembly 1. Then, install the lifting brake assembly 4 on the top of the oil tank assembly 3 and install the oil tank assembly 3 on the outside of the portable bracket assembly 1. This allows the interface of the oil tank assembly 3 to be extended through the lifting brake assembly 4 until it corresponds to the inside of the lifting sponge wiping assembly 2. During the movement of the portable bracket assembly 1, the track can be lubricated and maintained. After lubrication on the front side, the drying assembly 5 on the rear side can dry the lubricant on the track surface in time, thus improving the smoothness of the track during subsequent use. In subsequent use, first install the lifting sponge wiping assembly 2 in the middle of the support base 101. Then, use the push rod 103 in conjunction with the bottom moving wheels 102 for convenient and effortless movement. Simultaneously, install the oil tank assembly 3 on the mounting bracket 104 to complete the basic installation. Before moving, inject lubricating oil into the oil tank 301 through the oil inlet 302. The lifting and braking assembly 4 extends the lifting pipe 304 downwards, and the telescopic spring tube 303 stretches it until it reaches the inside of the limiting groove 204. The oil pump head 305 then injects lubricating oil into the sponge 205, which continues downwards. Squeezing the internal return spring 202 allows the sponge 205 to continue downwards, contacting tracks at different heights. During movement, the sponge's friction not only lubricates and maintains the track but also removes dirt, achieving efficient maintenance. After lubrication, the rear-mounted drying assembly 5 cures the previously maintained track. During curing, the bottom air outlet 503 of the fan box 501 dries the track, while the internal exhaust pump 504 absorbs impurities into the dust collection box 505. This completes the entire workflow.
