Description

Technical Field

[0001] This utility model relates to the field of railway rust removal technology, and in particular to an automatic railway rust removal and coating device. Background Technology

[0002] Chinese patent document CN223103387U discloses a rust removal device for railway rails, including a frame and a drive device mounted on the frame. The power output end of the drive device is connected to an output shaft. Two sets of rail rollers are installed on the frame. A transmission box and a positioning box are installed on one side of the frame. A rotating rod is installed on one side of the transmission box. A grinding roller is installed on the end of the rotating rod away from the frame. The rotating rod extends into the transmission box and is connected to a driven gear. The output shaft extends into the transmission box and is connected to a driving gear that meshes with the driven gear. The shaft end of the driving gear away from the output shaft is connected to a first pulley through a connecting shaft. In this invention, the grinding roller grinds and removes rust from the surface of the rail. Rust removal is carried out by the rotation of the grinding roller. It acts directly on the surface of the rail through mechanical friction, which can quickly and effectively remove rust and dirt. Rotational rust removal does not rely on chemical reagents and will not produce harmful waste liquid or exhaust gas. The device is also convenient to move along the rail for cleaning.

[0003] The aforementioned rust removal device for railway rails requires rust removal from the rail surface first, followed by coating with a brush or spray gun. These two processes are independent and require two separate operations, which reduces the efficiency of rail maintenance and increases the workload of staff. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic rust removal and coating device for railway rails, which can solve the problem that the above-mentioned rust removal devices for railway rails require rust removal from the rail surface first, and then coating with a brush or spray gun.

[0010] Preferably, an injection pipe is fixedly installed on the top of the storage tank.

[0011] Preferably, the bottom of the support base is provided with two sets of track rollers.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This automatic rail rust removal and coating device, through the combined use of a storage tank, a pump, an L-shaped pipe, a nozzle, and a partition cover, can simultaneously grind and remove rust while spraying an anti-rust coating onto the rust-removed rails.

The nozzle 404 is located inside the partition cover 405; the drying mechanism 5 is set on the top of the support base 1, and the drying mechanism 5 includes a strip-shaped air box 503 and an air outlet pipe 504. The strip-shaped air box 503 is fixedly installed at the bottom of the support base 1, and multiple sets of air outlet pipes 504 are fixedly installed at the bottom of the strip-shaped air box 503; the outer wall of the movable block 8 is fixedly installed with a motor 9 through a connecting plate, and the output shaft of the motor 9 is fixedly installed with a grinding block 10; the top of the storage tank 401 is fixedly installed with an injection pipe 3; and two sets of track rollers 2 are provided at the bottom of the support base 1.

[0017] Secondly, the spraying mechanism 4 also includes a material storage tank 401. The top of the support base 1 is fixedly connected to the bottom of the material storage tank 401. A material pump 402 is fixedly installed on one side of the material storage tank 401. The input end of the material pump 402 is connected to the inside of the material storage tank 401. It can spray anti-rust coating on the rust-removed rails while grinding and removing rust, combining rust removal and coating. Only one operation is needed, which improves the maintenance efficiency of the rails and reduces the workload of the staff.

[0018] Furthermore, the drying mechanism 5 also includes a blower 501, a C-tube 502, and an electric heater 505. The blower 501 is fixedly installed on the top of the support base 1. The C-tube 502 is fixedly installed at the output end of the blower 501. One end of the C-tube 502 is fixedly connected to and communicates with the front side of the strip-shaped air box 503. The electric heater 505 is fixedly installed on the inner wall of the strip-shaped air box 503. It can blow air onto the rails with the anti-rust coating sprayed on during the movement of the device, so that the coating can be dried as quickly as possible, ensuring the coating adhesion effect and improving the usability and practicality of the device.

[0019] Furthermore, a hollow block 6 is fixedly installed on the top of the support base 1, and a threaded rod 7 is threadedly installed on the top of the hollow block 6.

The threaded rod 7 is rotated, and under the limit of the inner wall of the hollow block 6, the movable block 8 is driven to move downward, which in turn drives the motor 9 to move downward, so that the bottom of the grinding block 10 is in contact with the rail surface, pushing the device to move. The motor 9 is turned on to drive the grinding block 10 to rotate, and the rotating grinding block 10 grinds and removes rust from the rail surface. Simultaneously, the material pump 402 is turned on to extract the paint from the storage tank 401 and inject it into the nozzle 404 through the L-shaped pipe 403. The paint is then sprayed onto the polished rail. The separator cover 405 can prevent paint from splashing. Then, the blower 501 is turned on and air is introduced into the strip air box 503 through the C-shaped pipe 502. The air entering the strip air box 503 is heated when it passes through the electric heater 505. The hot air is then blown onto the surface of the rail through the air outlet pipe 504 to dry the sprayed rail.
