Description

Technical Field

[0001] This utility model relates to the field of subway transportation technology; more specifically, it relates to a maintenance device for rail transportation. Background Technology

[0002] If the tracks are not adequately rust-proofed or regularly maintained, the surface will be more susceptible to corrosion. Therefore, rust removal from subway tracks is an important task for maintaining the safety and reliable operation of the subway system. Removing rust from the tracks can not only extend their service life but also ensure safe train operation.

[0003] Currently, existing maintenance devices for rail transportation often suffer from several drawbacks during use. Some existing devices can only grind a single rail, which may result in low efficiency in rust removal. Furthermore, some existing devices are not convenient for spraying rust removers onto the rails, which may affect the rust removal effect. Therefore, there is an urgent need for a maintenance device for rail transportation to solve these problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a maintenance device for rail transportation to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a maintenance device for rail transportation, comprising:

[0006] The main structure includes a support base, self-propelled wheels and grinding wheels, and each of the self-propelled wheels and grinding wheels is provided in two sets;

[0007] The rust removal structure includes a liquid storage tank and a spray pipe, with two sets of spray pipes, and the liquid storage tank is fixedly connected to one side of the upper surface of the support base.

[0008] Preferably, the two sets of self-propelled wheels are fixedly connected to both ends of one side of the lower surface of the support base, and a motor is installed on one side of the surface of each set of self-propelled wheels. Movable wheels are fixedly connected to both ends of the other side of the lower surface of the support base. When in use, the two sets of self-propelled wheels can be driven by the motor, so that they can move on the track by themselves, which can save the process of pushing by the worker and thus reduce the workload of the worker to a certain extent.

[0009] Preferably, a battery compartment is fixedly connected to the other side of the upper surface of the support base, and multiple sets of batteries are installed inside the battery compartment. Grinding wheels are connected to the bearings inside both ends of the support base. The multiple sets of batteries inside the battery compartment can provide power to the two sets of self-propelled wheels, drive motors and liquid pumps.

[0010] Preferably, drive motors are installed at both ends of the upper surface of the support base, and belts are fitted on the output ends of the two drive motors. The two belts are respectively fitted on the outer surface of one end of the two grinding wheels. After the two drive motors are started, their output ends will drive the two belts to drive the transmission. When the two belts are driven, they will drive the two grinding wheels to rotate, so that the two grinding wheels can be used to grind the track surface.

[0011] Preferably, an observation window is fixedly connected to the inside of one side surface of the liquid storage tank, and a sealing plug is inserted into the inside of the upper surface of the liquid storage tank. A liquid pump is installed inside the liquid storage tank. The observation window is made of transparent acrylic and has scales on its surface. This design allows the user to observe the remaining amount of rust remover inside the liquid storage tank in a timely manner.

[0012] Preferably, the output end of the pump is connected to a connecting pipe, and both sides of one end of the connecting pipe are connected to a diversion pipe. One end of each diversion pipe is connected to a spray pipe. After the pump is started, it can draw the rust remover from the storage tank and then deliver it to the inside of the two diversion pipes. Finally, it is sprayed onto the surface of the track through the two spray pipes.

[0013] The technical effects and advantages of this utility model are as follows: By starting two sets of self-propelled wheels, the equipment can move on the track. After the two sets of drive motors are started, their output ends will drive two sets of belts for transmission. When the two sets of belts are in transmission, they will drive two sets of grinding wheels to rotate. Thus, the two sets of grinding wheels can be used to grind the surface of the double track of a track. This design can greatly improve the efficiency of rust removal.

[0014] This invention allows the rust remover inside the storage tank to be drawn out by starting the pump, and then transported to the inside of two diversion pipes by the pump. Finally, it is sprayed onto the surface of the track through two sets of spray pipes. At this time, the rust on the track will react with the rust remover and loosen. This design can improve the rust removal effect when the two sets of grinding wheels are grinding. Attached Figure Description

[0022] Example 1

[0023] like Figures 1 to 3As shown, this utility model provides a maintenance device for rail transportation, including: a main structure 1, which includes a support base 11, self-propelled wheels 12, and grinding wheels 15. Two sets of self-propelled wheels 12 and grinding wheels 15 are provided. The two sets of self-propelled wheels 12 are fixedly connected to both ends of one side of the lower surface of the support base 11, and motors are installed on one side of each set of self-propelled wheels 12. Moving wheels 13 are fixedly connected to both ends of the other side of the lower surface of the support base 11. A battery compartment 14 is fixedly connected to the other side of the upper surface of the support base 11, and multiple sets of batteries are installed inside the battery compartment 14. Grinding wheels 15 are connected to the inner surfaces of both ends of the support base 11 by bearings. Drive motors 16 are installed at both ends of the middle position of the upper surface of the support base 11, and belts 17 are fitted onto the output ends of both sets of drive motors 16. The two sets of belts 17 are respectively fitted onto the outer surface of one end of each set of grinding wheels 15. The grinding wheels 15 are driven by multiple sets of batteries inside the battery compartment 14. The battery provides power to the two sets of self-propelled wheels 12, the drive motor 16, and the liquid pump 24. The battery compartment 14 has heat dissipation vents on both ends to prevent overheating. The two sets of self-propelled wheels 12 are driven by the motor, allowing them to move on the track. Both sets of self-propelled wheels 12 and the moving wheels 13 have locking grooves to engage with the track, improving stability during movement. This design eliminates the need for workers to push the equipment, reducing workload and increasing portability. After starting, the two drive motors 16 drive two sets of belts 17, which in turn rotate two sets of grinding wheels 15. This allows for simultaneous grinding of both tracks, significantly improving rust removal efficiency.

[0024] Example 2

[0025] like Figures 4 to 5As shown, this embodiment also proposes a rust removal structure 2, which includes a liquid storage tank 21 and a spray pipe 27. Two sets of spray pipes 27 are provided. The liquid storage tank 21 is fixedly connected to one side of the upper surface of the support base 11. An observation window 22 is fixedly connected to the inside of one side surface of the liquid storage tank 21. A sealing plug 23 is inserted into the inside of the upper surface of the liquid storage tank 21. A pump 24 is installed inside the liquid storage tank 21. The output end of the pump 24 is connected to a connecting pipe 25. Both sides of one end of the connecting pipe 25 are connected to diversion pipes 26, and one end of each diversion pipe 26 is connected to a spray pipe 27. The observation window 22 is made of transparent acrylic, and scales are provided on its surface. This design allows the user to quickly and accurately observe the rust removal process. The remaining amount of rust remover inside the storage tank 21 can be observed. The sealing plug 23 can improve the sealing of the storage tank 21, preventing dust and other impurities from entering the storage tank 21. After the pump 24 is started, the rust remover inside the storage tank 21 can be extracted and then delivered to the two-way flow pipes 26. Finally, it is sprayed onto the surface of the track through two sets of spray pipes 27. At this time, the rust on the track will react with the rust remover and loosen. This design can improve the rust removal effect when the two sets of grinding wheels 15 are grinding. (The motor and pump used in this application are products that can be purchased directly on the market. Their principles, connection methods and control methods are existing technologies known to those skilled in the art, so they will not be described in detail here.)

[0026] Working principle: When using the equipment, first place it on the track. Then, start the two sets of self-propelled wheels 12 to move the equipment on the track. Next, start the liquid pump 24 to extract the rust remover from the storage tank 21 and then deliver it to the two diversion pipes 26. Finally, spray it onto the surface of the track through the two sets of spray pipes 27. At this time, the rust on the track will react with the rust remover and loosen. Then, start the two sets of drive motors 16 and drive the two sets of belts 17 to drive the transmission. Then, the two sets of belts 17 will drive the two sets of grinding wheels 15 to rotate. At this time, the two sets of grinding wheels 15 can grind the rust on the track. The above is the complete working principle of this utility model.
