[0002] High-speed rail cabins and related supporting facilities involve a large number of skeleton structures (such as car bodies and bogies). To facilitate the assembly of the skeletons, they are usually processed in separate parts and then assembled as a whole (such as bolted assembly). Therefore, the drilling process is essential in the daily production and processing of high-speed rail skeletons. Since there are often debris and other structural residues in the drilled holes, a cleaning process is required after drilling. As shown in the high-speed rail skirt cleaning device (publication announcement number CN214767341U) disclosed on the China Patent Network, when this type of device is working, it clamps the skirt body by setting a clamping mechanism, and then drives the skirt body to rotate by a rotary motor. During the process of using a cleaning brush to rotate and clean the skirt body, water is also used for cleaning, realizing the two-in-one cleaning and rinsing, which greatly improves the working efficiency of high-speed rail skirt cleaning.
[0003] However, the aforementioned patented and existing high-speed rail frame cleaning equipment still has some shortcomings: While the existing method of rotating and cleaning the high-speed rail frame using fixed-point clamping offers flexibility, the clamping and fixing method often limits cleaning efficiency, requiring repeated disassembly and reassembly to complete the cyclic cleaning process for different frame structures. Therefore, those skilled in the art have provided a cleaning device for high-speed rail frame structures to solve the problems mentioned in the background art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution for a hole-cleaning device for high-speed rail frame structures: The hole-cleaning device for high-speed rail frame structures includes a hole-cleaning track 1, a hole-cleaning groove 4 in the middle of the hole-cleaning track 1, a hole-cleaning assembly above the hole-cleaning groove 4, and conveying grooves 2 on both sides of the hole-cleaning groove 4 along the slide rail direction of the hole-cleaning track 1. A clamping and conveying assembly is provided inside the conveying grooves 2. During the hole-cleaning process of the high-speed rail frame structure, the high-speed rail frame structure to be cleaned is placed in the hole-cleaning track 1. Utilizing the roller-type clamping and conveying characteristics of the clamping and conveying assembly, the high-speed rail frame structure is pushed forward in a clamping and conveying state to the bottom of the hole-cleaning assembly for a dynamic hole-cleaning process. Specifically:
[0023] The clamping and conveying assembly includes a transmission seat 10 symmetrically slidably connected to the bottom of the conveying trough 2. A first transmission motor 13 is provided at the bottom of the support of the transmission seat 10. A first transmission shaft 9 extending into the conveying trough 2 is provided at the output end of the first transmission motor 13. A clamping roller 3 is provided on the outside of the first transmission shaft 9. When clamping and conveying the high-speed rail frame structure, the two sets of clamping rollers 3 are first controlled to move in opposite directions to clamp the two sides of the high-speed rail frame structure and apply limiting and guiding pressure to the high-speed rail frame structure. Then, the first transmission motor 13 is controlled to drive the first transmission shaft 9 to rotate, which in turn drives the clamping roller 3 to rotate. By utilizing the friction between the clamping roller 3 and the high-speed rail frame structure, the high-speed rail frame structure is clamped while a forward thrust is applied to push the high-speed rail frame structure forward, thus performing a dynamic hole cleaning process.
[0024] It should be noted that a second drive shaft 15 is provided at the bottom of the hole-clearing track 1. A second drive motor 14 is provided at one end of the second drive shaft 15. The second drive shaft 15 is provided with a drive screw 16 directly opposite the bottom of the conveying trough 2 along its axial direction. The drive screw 16 is provided with drive sleeves 17 in a symmetrical manner along its axial direction. The drive sleeves 17 are connected to two sets of drive seats 10 respectively through the arm force connecting rod 18. The drive screw 16 is provided with positive and negative threads on both sides of the center line, which are adapted to the two sets of drive sleeves 17. By controlling the operation of the second drive motor 14, the second drive shaft 15 is driven to rotate, which in turn drives the drive screw 16 to rotate. The positive and negative threads on the drive screw 16 push the two sets of drive sleeves 17 to move in opposite directions. At the same time as the opposing displacement, the arm force connecting rod 18 drives the two sets of drive seats 10 to move synchronously in opposite directions, pushing the clamping rollers 3 to clamp on both sides of the high-speed rail frame structure in a clamping state, so as to limit and guide the high-speed rail frame structure.
[0025] In addition, the bottom of the conveying trough 2 is symmetrically provided with a relief groove 8 that is adapted to the transmission seat 10. The bottom of the conveying trough 2 is provided with a guide rail 11 in the same direction as the relief groove 8. The guide rail 11 is provided with a guide slide 12 that supports the transmission seat 10 along its guide rail direction. When the transmission seat 10 moves in opposite directions, the limiting combination of the guide rail 11 and the guide slide 12 can improve the stability of the transmission seat 10's displacement along the relief groove 8.
[0026] As a further embodiment, the hole cleaning assembly includes a support frame 20 located in the middle of the hole cleaning groove 4. At least one set of first electric push rods 5 are provided above the support frame 20. A support guide plate 21 is provided at the telescopic end of the first electric push rod 5. A second electric push rod 6 is symmetrically provided on one side of the support guide plate 21. An adjusting slide 22 is provided at the telescopic end of the second electric push rod 6. A high-pressure nozzle 7 is provided through the middle of the adjusting slide 22. An adjusting groove 23 adapted to the adjusting slide 22 is provided on the surface of the support guide plate 21, and the length of the adjusting groove 23 is... The width of the hole cleaning track 1 is the same. When the high-speed rail frame structure is pushed to the position directly below the high-pressure nozzle 7 in the hole cleaning groove 4, the first electric push rod 5 can be controlled to drive the support guide plate 21 to extend and retract, so that the high-pressure nozzle 7 moves down and probes into the screw hole of the high-speed rail frame structure. The high-pressure gas sprayed from the high-pressure nozzle 7 is used to clean the impurities inside the screw hole. The second electric push rod 6 can be controlled to extend and retract to adjust the downward position of the high-pressure nozzle 7 to align with the screw hole on the high-speed rail frame structure. The hole cleaning process is carried out on the conveyed screw hole by dynamically adjusting the hole cleaning method.
[0027] In addition, the bottom of the cleaning channel 4 is provided with a grid plate 19. By setting the grid plate 19 at the bottom of the cleaning channel 4, the high-pressure gas and the impurities it carries are connected, so that the impurities are flushed out along with the high-pressure gas.
[0028] The working principle of this utility model is as follows: When performing the hole cleaning process on the high-speed rail frame structure, the high-speed rail frame structure is placed in the hole cleaning track 1. Then, the second transmission motor 14 is controlled to drive the second transmission shaft 15 to rotate, which in turn drives the transmission screw 16 to rotate. The positive and negative threads on the transmission screw 16 push the two sets of transmission sleeves 17 to move in opposite directions. At the same time as the opposite displacement, the arm force connecting rod 18 drives the two sets of transmission seats 10 to move in opposite directions synchronously, pushing the clamping rollers 3 to clamp the two sides of the high-speed rail frame structure in a clamping state. Simultaneously, the first transmission motor 13 is controlled to drive the first transmission shaft 9 to rotate, which in turn drives the clamping rollers 3 to rotate. The friction between the clamping rollers 3 and the high-speed rail frame structure is used to clamp the high-speed rail frame structure while applying a forward thrust, pushing the high-speed rail frame structure forward into the hole cleaning groove 4 for a dynamic hole cleaning process.
[0029] Furthermore, when the high-speed rail frame structure is advanced to the position directly below the high-pressure nozzle 7 in the hole cleaning groove 4, the first electric push rod 5 can be controlled to drive the support guide plate 21 to extend and retract, so that the high-pressure nozzle 7 moves down and probes into the screw hole of the high-speed rail frame structure. The high-pressure gas sprayed from the high-pressure nozzle 7 is used to clean the impurities inside the screw hole. The second electric push rod 6 can be controlled to extend and retract to adjust and align the downward position of the high-pressure nozzle 7 to align with the screw hole on the high-speed rail frame structure. The screw hole is dynamically cleaned by adjusting the dynamic adjustment method.
[0030] Furthermore, after the cleaning of a single high-speed rail frame structure is completed, only cyclic feeding is required to form a continuous and uninterrupted cleaning operation.
[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
