A plurality of connecting ribs are provided between the mounting portion and the sliding sleeve, and the plurality of connecting ribs are evenly spaced along the circumference of the mounting portion. In addition, the polishing piece 4 is spaced apart from the inner wall of the sliding sleeve to ensure air circulation.

[0045] In some embodiments, the above-mentioned mobile frame 3 can be used as follows Figure 1 The structure shown. Figure 1 The movable frame 3 is provided with a U-shaped groove for mounting the nozzle 9, and two fasteners 91 for fixing the nozzle 9 to the inside of the U-shaped groove are threadedly connected to the nozzle 9. A U-shaped groove for mounting the nozzle 9 is provided on the movable frame 3. The U-shaped groove is located on the side of the sleeve 6 away from the fixed frame 2. Two fasteners 91 are threadedly connected to the nozzle 9. The two fasteners 91 are respectively located on the upper and lower sides of the movable frame 3. By rotating the fasteners 91, the portion of the movable frame 3 provided with the U-shaped groove can be clamped between the two fasteners 91, thereby fixing the nozzle 9 to the movable frame 3.

[0046] Specifically, in this embodiment, when the fixing frame 2 is fixed to the rail 1, the liquid outlet end of the nozzle 9 is set toward the bottom of the rail 1. After the rust and dust removal is completed, the coupling agent can be delivered to the nozzle 9 through the external infusion device, so that the coupling agent is evenly sprayed on the bottom of the rail 1.

[0047] In some embodiments, the fixing frame 2 may be configured as follows: Figure 1 、 Figure 2 See also Figure 1 、 Figure 2 The fixing frame 2 is provided with a slot for being mounted on the rail 1, and a magnet 21 for being attracted to the rail 1 is installed on the inner wall of the slot. A slot that matches the shape of the rib plate at the bottom of the rail 1 is provided on one side of the fixing frame 2. A magnet 21 is embedded on the inner wall of the slot. When in use, the rib plate at the bottom of the rail 1 can be directly inserted into the slot. The fixing frame 2 can be fixed to the bottom of the rail 1 by the magnet 21. The structure is simple, and the fixing frame 2 can be easily installed on or removed from the rail 1.

[0048] Optionally, in this embodiment, a push rod is threadedly connected to the side wall of the slot on the fixing frame 2, and the end of the push rod rests on the rail 1, thereby enhancing the stability of the connection between the fixing frame 2 and the rail 1.

[0049] In some embodiments, the fixing frame 2 may be configured as follows: Figure 1 、 Figure 2 See also Figure 1 、 Figure 2 A push rod 22 is slidably provided on the fixed frame 2, one end of the push rod 22 being located outside the fixed frame 2 and the other end being fixedly mounted on the movable frame 3. There are two push rods 22, both of which are slidably provided on the fixed frame 2, and the movable frame 3 is fixedly mounted on the ends of the push rods 22, with the other ends of the push rods 22 being located outside the fixed frame 2. When in use, the operator can move the movable frame 3 under the rail 1 by pushing the push rods 22, resulting in a simple structure and easy operation.

[0050] Preferably, in this embodiment, a cylinder or electric push rod 22 for pushing the push rod 22 to move is also installed on the fixing frame 2, thereby saving manpower.

[0051] Optional, such as Figure 4 As shown, a blocking plate 10 is provided between the polishing element 4 and the spray head 9. A rubber strip is provided on top of the blocking plate 10, which adheres to the bottom of the rail. The blocking plate 10 prevents direct contact between polishing dust and the sprayed coupling agent, allowing for simultaneous polishing and spraying operations without having to wait until polishing is complete before spraying, thereby improving overall polishing and spraying efficiency. The rubber strip adheres to the bottom of the rail, while isolating dust and coupling agent. It also allows for further cleaning and scraping of dust and rust on the bottom of the rail, improving both dust and rust removal.

[0052] Example 2

[0053] The difference between this embodiment and the first embodiment is that Figure 4 and Figure 5 As shown, a clearance groove 23 is provided at the connection between the fixing frame 2 and the push rod 22, which is used to make way for the polishing piece 4. With such a configuration, the present device can realize that the polishing piece 4 can complete the polishing operation of the entire transverse portion of the bottom surface of the rail at one time, thereby improving the polishing efficiency. In the first embodiment, because the fixing frame 2 blocks the polishing piece 4, the polishing piece 4 cannot move within the full transverse range of the bottom surface of the rail. It can only polish more than half of the transverse portion of the bottom surface of the rail first, and then the present device is reversed and installed to the other side of the rail, and then polished once more to complete the polishing operation of the entire transverse portion of the bottom surface of the rail. The weld 11 is a key weak area of ​​the rail and requires intensive ultrasonic testing. Through the device provided in this embodiment, the polishing, rust removal and coupling agent spraying operations at the bottom surface weld 11 of the rail can be completed at one time.
