Description

Technical Field

[0001] This utility model relates to the field of cement silo cleaning technology, specifically to a cement silo demolition robot. Background Technology

[0002] A cement silo is a cylindrical structure used to store cement. Because cement must undergo physical testing at a certain age, cement plants must have cement silos of a certain capacity. Typical cement silos are reinforced concrete structures, while smaller silos may be made of steel plates or brick and stone.

[0003] After a certain period of use, cement silos tend to develop cement buildup on their walls. Currently, mechanical cleaning is inconvenient, so manual cleaning is generally used. The main steps are as follows: a worker, wearing a safety harness and fall arrestor, stands inside the suspended basket, holding tools and securing it. Entering through the manhole, the operator manually lowers the basket near the ladder. Once at a certain point, the worker begins clearing the cement buildup around the ladder, the manhole, and the sides. The basket is then raised and lowered using a cable reel.

[0004] Currently, when cleaning, if a hard block with a loose wall is encountered, it can be poked down with a long stick. However, when the wall is thick and hard, it is necessary to use a pneumatic pick to loosen it and make it collapse. However, if the workers carry the equipment and suspend it in the air, their arms will quickly become fatigued, resulting in a high labor intensity for cleaning. Furthermore, the efficiency of dismantling cement silos will decrease after physical strength declines. Therefore, a cement silo dismantling robot is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cement silo demolition robot to address the problem that workers carrying equipment in the air experience rapid arm fatigue, resulting in high labor intensity for cleaning and reduced efficiency in dismantling cement silos after physical exhaustion.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A cement silo demolition robot includes a base plate on which a support column is rotatably mounted. An elastic reset mechanism is provided between the support column and the base plate. A support block is fixedly mounted at one end of the support column, and a power box is fixedly mounted on the side wall of the support block. A power output mechanism is provided inside the power box, and a moving rod is slidably inserted through the side wall of the power box. The moving rod is connected to the power output mechanism via a transmission connection. Scraping mechanisms are provided at both ends of the moving rod.

[0008] Preferably, the elastic reset mechanism includes a support bearing, which is embedded in the base plate. The support column is fixedly inserted into the support bearing, and a limiting plate is fixedly sleeved on the side wall of the support column. A reset spring is fixedly installed on one side of the limiting plate. The reset spring is slidably sleeved on the outside of the support column, and one end of the reset spring is fixedly installed on the base plate.

[0009] Preferably, a protective sleeve is fixedly installed on the side wall of the limiting plate, and the protective sleeve is located outside the reset spring. The protective sleeve is arranged in a tubular structure.

[0010] Preferably, the power output mechanism includes a stepper motor, which is fixedly mounted on the side wall of the power box. One end of the stepper motor output shaft passes through the power box and is fixedly mounted with a transmission shaft. A transmission gear is fixedly mounted on the side wall of the transmission shaft and is in contact with the moving rod. A detachable movable cover is provided on the upper side of the power box.

[0011] Preferably, the movable rod includes multiple connecting tubes, one end of which is fixedly fitted with a connector, and the connector has a plug hole on its side wall, and the connecting tube has a mating hole on its side wall.

[0012] Preferably, the scraping mechanism includes a U-shaped plate, a scraper is fixedly installed on one side of the U-shaped plate, and a striking pin is fixedly installed on the side wall of the U-shaped plate. A connecting shaft is provided on the side wall of the U-shaped plate and is rotatably mounted on a connecting pipe. A torsion spring is fixedly installed on the side wall of the connecting pipe and is slidably sleeved on the side wall of the connecting shaft. One end of the torsion spring is fixedly installed on the U-shaped plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, when workers enter the suspended basket, they carry this device in. The device is then placed inside the basket via a base plate. After descending to a designated height, multiple connecting pipes are assembled to extend the length of the entire moving rod. Next, a stepper motor is started, causing the stepper motor to drive the transmission shaft and transmission gear to rotate. The transmission gear then drives the moving rod to move. The scraper and impact pin are then brought close to the inner wall of the cement silo. As the stepper motor continuously drives the moving rod to one side, the scraper and impact pin remove the cement clumps on the inner surface of the silo, eliminating the need for manual cleaning with hand tools. This not only reduces the labor intensity of workers but also maintains cleaning efficiency, avoiding a decrease in cleaning efficiency due to manual labor. Attached Figure Description

[0024] like Figure 1-4 As shown, a cement silo demolition robot includes a base plate 1, on which a support column 2 is rotatably mounted. An elastic reset mechanism is provided between the support column 2 and the base plate 1. The elastic reset mechanism includes a support bearing 16, which is embedded in the base plate 1. The support column 2 is fixedly inserted into the support bearing 16, so that the support column 2 can rotate around the base plate 1.

[0025] A limiting plate 3 is fixedly sleeved on the side wall of the supporting column 2. A return spring 15 is fixedly installed on one side of the limiting plate 3. The return spring 15 is slidably sleeved on the outside of the supporting column 2, and one end of the return spring 15 is fixedly installed on the base plate 1. The return spring 15 allows the supporting column 2 to easily return to its original position after rotation by its elastic force. A protective sleeve 4 is fixedly installed on the side wall of the limiting plate 3, and the protective sleeve 4 is located outside the return spring 15. The protective sleeve 4 has a tubular structure, which helps to protect the return spring 15 and other structures, preventing external environmental interference with the operating parts.

[0026] A support block 5 is fixedly installed at one end of the support column 2, and a power box 9 is fixedly installed on the side wall of the support block 5. A power output mechanism is provided inside the power box 9. The power output mechanism includes a stepper motor 11, which is fixedly installed on the side wall of the power box 9. One end of the output shaft of the stepper motor 11 passes through the power box 9 and is fixedly installed with a transmission shaft 18. A transmission gear 17 is fixedly installed on the side wall of the transmission shaft 18, and the transmission gear 17 is in contact with the moving rod 12. A detachable movable cover 10 is provided on the upper side of the power box 9. The movable cover 10 can easily open the power box 9, thereby facilitating the maintenance of the internal components.

[0027] A movable rod 12 is slidably inserted through the side wall of the power box 9. The movable rod 12 includes multiple connecting pipes 1201. The bottom of each connecting pipe 1201 is provided with a serrated groove. The connecting pipe 1201 and the transmission gear 17 are meshed and driven. When the movable rod 12 is continuously driven to move to one side by the stepper motor 11, it can replace the manual removal of cement blocks on the surface of the warehouse with tools. Therefore, it is no longer necessary to clean with manual tools. This not only reduces the labor intensity of the staff, but also maintains the cleaning efficiency and avoids the situation where the cleaning efficiency is reduced due to the consumption of manual physical strength.

[0028] A connector 1204 is fixedly installed at one end of the connecting pipe 1201, and a plug hole 1203 is provided on the side wall of the connector 1204. A mating hole 1202 is provided on the side wall of the connecting pipe 1201. The mating hole 1202 and the plug hole 1203 are correspondingly provided, and both have internal threads on their inner walls. A positioning bolt is installed in the mating hole 1202 and the plug hole 1203. The positioning bolt can better fix the two connecting pipes 1201.

[0029] Scraping mechanisms are provided at both ends of the moving rod 12. The scraping mechanism includes a U-shaped plate 13. A scraper 7 is fixedly installed on one side of the U-shaped plate 13, and a striking pin 6 is fixedly installed on the side wall of the U-shaped plate 13. The striking pin 6 can break up harder lumps, while the scraper 7 can scrape off powderier lumps. A connecting shaft 8 is provided on the side wall of the U-shaped plate 13, and the connecting shaft 8 is rotatably mounted on the connecting pipe 1201. A torsion spring 14 is fixedly installed on the side wall of the connecting pipe 1201. The torsion spring 14 is slidably sleeved on the side wall of the connecting shaft 8, and one end of the torsion spring 14 is fixedly installed on the U-shaped plate 13. The torsion spring 14 can drive the U-shaped plate 13 to reset.

[0030] In summary: When workers enter the suspended platform, they carry this device inside. The device is then placed inside the platform via the base plate 1. After descending to a designated height, multiple connecting pipes 1201 are assembled onto the connecting pipes 1201 within the power box 9, thereby extending the length of the entire moving rod 12. Next, the stepper motor 11 is activated, causing the transmission shaft 18 and transmission gear 17 to rotate. The transmission gear 17 then moves the moving rod 12. The scraper plate 7 and impact pin 6 are then brought close to the inner wall of the cement silo. As the stepper motor 11 continuously moves the moving rod 12 to one side, the scraper plate 7... The impact pin 6 removes cement clumps from the inner surface of the silo. When the moving rod 12 drives the scraper 7 and impact pin 6 to continuously press to one side and change the angle, the moving rod 12 can be rotated through the power box 9 and the support block 5. Then the support block 5 can be rotated around the base plate 1 through the support column 2 and the support bearing 16. Then the support column 2 will be reset by the return spring 15. When a huge angle change occurs, the scraper 7 and the torsion spring 14 can change the angle through the connecting shaft 8, and the connecting shaft 8 can be reset again by the torsion spring 14, thereby completing the removal of the inner wall of the cement silo.
