During the rotation of the rack 17, the scraper 16 can be driven to rotate on the surface of the scraper ring 12. When the guide rod 15 rotates, the slider 14 can slide inside the scraper ring 12, and then the guide rod 15 can be limited when it rotates. This step can be used to clean the dust adhered to the middle of the hydraulic press body 1 during the use of the hydraulic press body 1, thereby reducing the influence of dust on the work of the hydraulic press body 1, and further reducing the influence of the special vehicle on the special vehicle due to the failure of the hydraulic press body 1 when the special vehicle is working.

[0024] like Figure 1-3As shown, a threaded rod 2 is fixedly connected to the middle of the hydraulic press body 1; a fixing plate 21 is slidably connected to the end of the threaded rod 2; a bolt 22 is rotatably connected to the middle of the threaded rod 2; an oil circuit pipe 23 is fixedly connected to the middle of the fixing plate 21; the oil circuit pipe 23 is slidably connected to the hydraulic press body 1; during operation, when the hydraulic press body 1 is used to assist special vehicles, the fixing plate 21 can be placed in the middle of the threaded rod 2, and then the fixing plate 21 and the threaded rod 2 are fixed by bolts 22, so that the oil circuit pipe 23 can be fixedly connected to the connection between the hydraulic press body 1. This step can reduce the loosening of the connection between the oil circuit pipe 23 and the hydraulic press body 1 when the hydraulic press body 1 needs to be used for work, thereby reducing the situation where the hydraulic oil inside the hydraulic press body 1 leaks and causes the hydraulic press body 1 to fail to work.

[0025] like Figure 4 As shown, a hidden groove 3 is opened in the middle of the retaining ring 11; a plurality of groups of hidden grooves 3 are arranged in the middle of the retaining ring 11; a small spring 31 is fixedly connected in the middle of the hidden groove 3; the end of the small spring 31 is fixedly connected to the scraper ring 12; during operation, when the scraper ring 12 is used to clean the dust in the middle of the hydraulic press body 1, the elastic force of the scraper ring 12 by the small spring 31 can make the scraper ring 12 move back and forth continuously in the middle of the hydraulic press body 1. This step can reduce the situation where a large amount of dust adheres to the middle of the hydraulic press body 1 through the continuous movement of the scraper ring 12 when the hydraulic press body 1 is working. At the same time, the scraper ring 12 can be vibrated by the action of the small spring 31 to shake off the dust in the middle of the scraper ring 12.

[0026] like Figure 1-2 As shown, a collecting chamber 4 is fixedly connected to the middle of the scraper 16; a baffle 41 is fixedly connected to the middle of the collecting chamber 4; during operation, after the scraper 16 is used to clean the dust in the middle of the scraper circle 12, the collecting chamber 4 can be used to collect the dust in the middle of the scraper circle 12, and then the baffle 41 can be used to shield the dust collected in the middle of the collecting chamber 4. This step can reduce the situation where the cleaned dust is splashed everywhere in the middle of the scraper circle 12 after the scraper 16 is used to clean the dust, and the baffle 41 can reduce the situation where the dust collected in the collecting chamber 4 is scattered to the outside.

[0027] like Figure 1-3 As shown, a protective spring 5 is fixedly connected to the middle of the bolt 22; the end of the protective spring 5 is slidably connected to the hydraulic press body 1; during operation, when 32 is connected to the hydraulic press body 1, the oil pipe 23 and the hydraulic press body 1 can be separated by the protective spring 5. This step can reduce the collision between the oil pipe 23 and the hydraulic press body 1 when installing the oil pipe 23, and further protect the oil pipe 23 during the installation process.

[0028] like Figure 1-2 As shown, the middle part of the slider 14 is slidably connected with a guide ring 6; during operation, when the slider 14 slides inside the slide groove 13, the guide ring 6 can be used to guide the position of the slider 14. This step can reduce the situation where the slider 14 falls off from the middle part of the slide groove 13 during the rotation of the slider 14, thereby protecting the cleaning work of the scraper ring 12.

[0029] like Figure 1-2 As shown, a scraper blade 7 is fixedly connected to the middle of the collecting chamber 4; the scraper blade 7 is slidably connected to the scraper ring 12; during operation, when the scraper 16 is rotated, the scraper blade 7 can be rotated along with the scraper 16. This step can clean the dust in the middle of the scraper ring 12 through the rotation of the scraper blade 7, thereby improving the cleaning efficiency of the scraper ring 12.

[0030] Working principle: during operation, when the hydraulic press body 1 is used to work, the scraper ring 12 can be used to clean the dust in the middle of the hydraulic press body 1 as the hydraulic press body 1 works, and then the motor 18 can be operated, and then the gear 19 can be used to drive the rack 17 to rotate. During the rotation of the rack 17, the scraper 16 can be driven to rotate on the surface of the scraper ring 12. When the guide rod 15 rotates, the slider 14 can slide inside the scraper ring 12, and then the guide rod 15 can be limited when it rotates. This step can be used to clean the dust adhering to the middle of the hydraulic press body 1 during the use of the hydraulic press body 1, thereby reducing the situation where the dust affects the work of the hydraulic press body 1, and thereby reducing the damage caused by the hydraulic press when the special vehicle is working. In case of a failure of the main body 1 affecting the special vehicle, when the hydraulic press main body 1 is used to assist the special vehicle, the retaining plate 21 can be placed in the middle of the threaded rod 2, and then the retaining plate 21 and the threaded rod 2 can be fixed by the bolt 22, so that the oil circuit pipe 23 can be fixedly connected to the connection of the hydraulic press main body 1. This step can reduce the looseness of the connection between the oil circuit pipe 23 and the hydraulic press main body 1 when the hydraulic press main body 1 is needed to work, and thus reduce the situation where the hydraulic press main body 1 cannot work due to the leakage of hydraulic oil inside the hydraulic press main body 1. When the scraper ring 12 is used to clean the dust in the middle of the hydraulic press main body 1, the small spring 31 can be used to act on the elastic force of the scraper ring 12, so that the scraper ring 12 can be in the hydraulic press. The middle part of the main body 1 moves back and forth continuously. This step can be performed when the hydraulic press body 1 is working. The continuous movement of the scraper ring 12 can reduce the occurrence of a large amount of dust sticking to the middle part of the hydraulic press body 1. At the same time, the scraper ring 12 can be vibrated by the action of the small spring 31, and the dust in the middle part of the scraper ring 12 can be shaken off. After the scraper 16 is used to clean the dust in the middle part of the scraper ring 12, the collection chamber 4 can be used to collect the dust in the middle part of the scraper ring 12, and then the baffle 41 can be used to block the dust collected in the middle part of the collection chamber 4. This step can be performed after the scraper 16 is used to clean the dust. It can reduce the situation where the cleaned dust splashes everywhere in the middle part of the scraper ring 12. The baffle 41 can reduce the dust collected inside the collection chamber 4. In case of dust spilling outward, when connecting 32 to the hydraulic press body 1, the oil pipe 23 and the hydraulic press body 1 can be separated by the protective spring 5. This step can reduce the collision between the oil pipe 23 and the hydraulic press body 1 when installing the oil pipe 23, and thus the oil pipe 23 can be protected during the installation process. When the slider 14 slides inside the slide groove 13, the guide ring 6 can be used to guide the position of the slider 14. This step can reduce the slider 14 from falling off from the middle of the slide groove 13 during the rotation of the slider 14, and thus the cleaning work of the scraper ring 12 can be protected. When the scraper 16 is rotated, the scraper 7 can be rotated together with the scraper 16.In this step, the dust in the middle of the scraper ring 12 can be cleaned by the rotation of the scraper blade 7, thereby improving the cleaning efficiency of the scraper ring 12.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
