Description

Technical Field

[0001] This invention relates to the field of flatness control technology, specifically to a flatness control mechanism for factory floor construction. Background Technology

[0002] During factory floor construction, various factors, such as material properties, construction techniques, and environmental factors, can cause deviations in the flatness of the floor. As the foundation for equipment operation, the flatness of the factory floor has a significant impact on the stability, accuracy, and lifespan of the equipment. An uneven floor can cause vibration, displacement, and wear during equipment operation, and in severe cases, may even lead to safety accidents. Furthermore, the floor needs to withstand the loads of various heavy equipment and goods, as well as frequent vehicle and personnel traffic. Flatness control is a crucial aspect of factory floor construction and directly affects the floor's performance and durability. Flatness requirements are mainly reflected in the uniformity and smoothness of the floor surface. Through reasonable construction methods and material selection, it is ensured that the floor surface is free of obvious bumps and cracks.

[0003] Existing factory floor flatness control mechanisms typically use advanced laser screed machines to replace traditional equipment. These machines utilize hydraulic devices to drive the screed head, working in conjunction with a laser system and computer control system to automatically level the floor. However, during the screed head's operation, manual labor is required to continuously fill the screed path with concrete for pre-leveling. This is because gaps or unevenness may exist during concrete laying; without pre-leveling, defects may appear on the leveled floor. Manual pre-leveling of concrete may not match the machine's speed, and may even result in overfilling or underfilling, affecting the screed head's control over floor flatness. Therefore, we propose a flatness control mechanism for factory floor construction. Summary of the Invention

[0004] The purpose of this invention is to provide a flatness control mechanism for factory floor construction, so as to solve the problems mentioned in the background art.

The end of each magnetic suction groove is connected to a second straight groove. The end of each second straight groove is connected to a second telescopic groove. Each second telescopic groove is connected to the corresponding first straight groove.

[0008] Preferably, a device compartment is fixedly installed on the fixed plate, and a rotating shaft is rotatably installed inside the device compartment. The rotating shaft is provided with a reciprocating screw groove, and a limiting member is sleeved on the rotating shaft. A limiting block that cooperates with the reciprocating screw groove is fixedly installed on the inner wall of the limiting member. A guide groove for limiting the limiting member is provided on the device compartment. Several first elastic rods are fixedly connected between the lower end of the limiting member and the packing plate, and several second elastic rods are fixedly connected between the lower end of the limiting member and the cleaning plate.

[0009] Preferably, a sleeve is fixedly installed inside the electric telescopic pole, a rotating cylinder is fitted inside the sleeve, and a rotating rod is fitted inside the rotating cylinder. One end of the rotating rod is rotatably connected to the inner wall of the electric telescopic pole. Both the inner wall of the sleeve and the inner wall of the rotating cylinder are provided with threaded grooves. Both the outer wall of the rotating cylinder and the outer wall of the rotating rod are fixedly installed with threaded strips that mate with the threaded grooves. Both the rotating rod and the rotating shaft are fixedly installed with transmission wheels, and a flexible transmission belt is installed between the two transmission wheels.

[0010] Preferably, the magnetic attraction force of the magnetic block on the magnetic rod is greater than the elastic force of the second elastic rod.

[0011] Preferably, a spiral auger is rotatably mounted on the lower end of the fixed plate, and a motor for driving the spiral auger is fixedly mounted on one side of the fixed plate. The lowest point of the spiral auger's movement trajectory is on the same horizontal plane as the lower end of the vibrating plate and the lower end of the scraper.

[0012] Preferably, when the telescopic column is located in the inclined groove, the lower end of the filler plate is located in the concrete mortar, and when the magnetic suction rod is located in the second straight groove, the upper end of the cleaning plate is located above the concrete mortar.

[0015] Preferably, a guide plate is fixedly installed at one end of the fixing plate to prevent concrete mortar scraped by the auger from splashing onto the flat area.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention utilizes the retraction of an electric telescopic rod to drive the rotation of a rotating rod and shaft, causing the limiting member to reciprocate. When the limiting member moves forward, it drives the filling plate to move obliquely upward along the inclined groove, scraping up the uneven concrete mortar and filling it into the movement trajectory of the scraper. When the limiting member moves in the opposite direction, the telescopic column is limited by the guide block and moves along the first straight groove. After the telescopic column moves to the beginning of the first straight groove, the filling plate is subjected to the elastic force of the first elastic rod and moves downward along the first telescopic groove, inserting into the concrete mortar. With the reciprocating movement of the limiting member, the filling material is continuously added to the movement trajectory of the scraper.

[0018] This invention utilizes the elastic force of the second elastic rod to pull the cleaning plate, causing the magnetic suction rod to move upward along the second telescopic groove to the end of the second straight groove in the initial state. During the forward movement of the limiting member, the cleaning plate will be driven to move along the second straight groove to the end of the magnetic suction groove. After the magnetic suction rod moves to the beginning of the second straight groove, it is attracted by the magnetic force of the magnetic block and moves downward along the magnetic suction groove to the end of the first straight groove, causing the second elastic rod to be stretched, and at the same time scraping off the concrete mortar adhering to the scraper. When the limiting member moves in the opposite direction, it will drive the cleaning plate to the end of the first straight groove and scrape off the excess concrete mortar accumulated on the scraper's movement trajectory, thus improving the scraping effect of the scraper.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10This invention provides a technical solution: a flatness control mechanism for factory floor construction, comprising a support 1, an electric telescopic rod 2 fixedly installed on the support 1, a leveling head 3 fixedly installed at one end of the electric telescopic rod 2, two cylinders 4 fixedly installed on the leveling head 3, and a laser leveling device 5 (the laser leveling device 5 is a known existing device, specifically including Topcon series RL-H5A, RL-SV2S, RL-200, etc.) fixedly installed between the output ends of the two cylinders 4, a vibrating plate 7 fixedly installed on the fixed plate 6, a vibration motor 8 fixedly installed on the vibrating plate 7, and a scraper 12 fixedly installed on the fixed plate 6. The scraper 12 is configured as a V-shaped structure to prevent concrete mortar from spreading to both ends when the electric telescopic rod 2 is retracted. A spiral auger 9 is rotatably installed at the lower end of the fixed plate 6, and a device for driving the spiral auger 9 is fixedly installed on one side of the fixed plate 6. The lowest point of the movement trajectory of the motor 10 and the spiral auger 9 is on the same horizontal plane as the lower end of the vibrating plate 7 and the lower end of the scraper 12. One end of the fixed plate 6 is fixedly equipped with a guide plate 11 to prevent the spiral auger 9 from scraping out excess concrete mortar and splashing onto the leveling area. During operation, the support 1 is stopped in a suitable position, the electric telescopic rod 2 is extended, and the laser leveling instrument 5 controls the cylinder 4 to work, so that the lowest point of the spiral auger 9's movement trajectory is at a predetermined height along with the lower end of the vibrating plate 7 and the lower end of the scraper 12. The electric telescopic rod 2 retracts, and the scraper 12 scrapes away the excess concrete mortar for the first leveling. Then, the motor 10 drives the spiral auger 9 to rotate, and the spiral auger 9 performs a second leveling of the concrete mortar surface. The excess concrete mortar is discharged to the unleveled area along the rotation direction of the spiral auger 9. The vibration motor 8 drives the vibrating plate 7 to perform rapid small-amplitude vibration, making the concrete mortar surface smoother and completing the control of the floor flatness.

[0032] A sleeve 33 is fixedly installed inside the electric telescopic rod 2. A rotating cylinder 34 is fitted inside the sleeve 33, and a rotating rod 35 is fitted inside the rotating cylinder 34. One end of the rotating rod 35 is rotatably connected to the inner wall of the electric telescopic rod 2. Threaded grooves 37 are provided on the inner walls of both the sleeve 33 and the rotating cylinder 34. Threaded strips 36 that mate with the threaded grooves 37 are fixedly installed on the outer walls of both the rotating cylinder 34 and the rotating rod 35. A device compartment 26 is fixedly installed on the fixed plate 6. A rotating shaft 27 is rotatably installed inside the device compartment 26. Transmission wheels 39 are fixedly installed on both the rotating rod 35 and the rotating shaft 27. A transmission mechanism is installed between the two transmission wheels 39. The flexible transmission belt 40, the device chamber 26, and the electric telescopic rod 2 all have through holes. The transmission belt 40 passes through the through holes, and there are also deflecting bristles at the edge of the through holes. The deflecting bristles prevent concrete splashed onto the transmission belt 40 from being carried into the device chamber 26 and the electric telescopic rod 2, thus affecting the normal operation of the equipment. They can also limit the transmission belt 40 when the distance between the device chamber 26 and the electric telescopic rod 2 is too close, preventing it from loosening. The rotating shaft 27 is provided with a reciprocating screw groove 28, and a limiting member 29 is sleeved on the rotating shaft 27. The inner wall of the limiting member 29 is fixedly installed with a reciprocating screw groove 28. The device compartment 26 is equipped with a guide groove 38 for limiting the limiting component 29. During the extension process of the electric telescopic rod 2, the rotating drum 34 is pulled out from the sleeve 33, and the rotating rod 35 is also pulled out from the rotating drum 34. Through the cooperation of the threaded groove 37 and the threaded strip 36, the rotating rod 35 rotates. Since the electric telescopic rod 2 does not require leveling work during the extension process, the cylinder 4 retracts, the distance between the device compartment 26 and the electric telescopic rod 2 is relatively close, the transmission belt 40 is not straightened, the friction between the transmission belt 40 and the transmission wheel 39 is small, and there is no transmission; when the electric When the telescopic rod 2 retracts, the cylinder 4 operates, bringing the device chamber 26 and the electric telescopic rod 2 to a predetermined distance. The transmission belt 40 is straightened, and the friction between the transmission belt 40 and the transmission wheel 39 is sufficient for transmission. As the electric telescopic rod 2 retracts, the rotating drum 34 moves into the sleeve 33, and the rotating rod 35 also moves into the rotating drum 34. The rotating rod 35 rotates again, driving the rotating shaft 27 to rotate. Through the cooperation of the reciprocating screw groove 28 and the limiting block 30, and the limiting member 29 by the guide groove 38, the limiting member 29 continuously slides back and forth along the guide groove 38 when the electric telescopic rod 2 retracts.

[0033] Two limiting plates 15 are fixedly installed on one side of the scraper 12. A filling plate 13 for filling concrete mortar onto the movement trajectory of the scraper 12 is slidably installed between the two limiting plates 15. Several first elastic rods 31 are fixedly connected between the lower end of the limiting member 29 and the filling plate 13. Telescopic columns 24 are fixedly installed at both ends of the filling plate 13. Each limiting plate 15 is provided with a first straight groove 16 for limiting the telescopic column 24. The first end of each first straight groove 16 is connected to a first telescopic groove 17, and the end of the first telescopic groove 17 is connected to an inclined... The inclined groove 18 is connected at its end to the first straight groove 16, and a guide block 19 for limiting the telescopic column 24 is fixedly installed at the connection. The telescopic column 24 is located in the inclined groove 18, and the lower end of the filling plate 13 is located in the concrete mortar. When the limiting member 29 reciprocates, in the initial state, the first elastic rod 31 is in a compressed state, and the filling plate 13 is located at the beginning of the inclined groove 18. When the limiting member 29 moves forward, it drives the filling plate 13 to move obliquely upward along the inclined groove 18, and the first elastic rod 31 is gradually compressed. Due to the telescopic column 24 Located in the inclined groove 18, with the lower end of the filler plate 13 submerged in concrete mortar, the filler plate 13, as it moves along the inclined groove 18, scrapes up the uneven concrete mortar and fills the movement trajectory of the scraper plate 12, ensuring sufficient concrete slurry on the scraper plate 12's movement trajectory. When the filler plate 13 reaches the end of the inclined groove 18, the telescopic column 24 is compressed on the inclined surface passing through the guide block 19. After the telescopic column 24 enters the first straight groove 16, its own elasticity causes it to extend and return to its original position. At this time, the lower end of the filler plate 13 will move into the concrete slurry... Above the mortar, the limiting member 29 will move in the opposite direction, and the telescopic column 24 will be limited by the guide block 19 and will move along the first straight groove 16. At this time, the first elastic rod 31 is always in a compressed state, and the lower end of the filling plate 13 will not contact the concrete mortar. After the telescopic column 24 moves to the first end of the first straight groove 16, the filling plate 13 will be subjected to the elastic force of the first elastic rod 31 again and move downward along the first telescopic groove 17 and insert into the concrete mortar. As the limiting member 29 moves back and forth, it continuously fills the scraper 12 along its movement trajectory.

[0034] A cleaning plate 14 for scraping off excess concrete mortar from the scraper 12 is slidably installed between two limiting plates 15. The cleaning plate 14 is also set in a V-shape corresponding to the scraper 12. The lower end of the cleaning plate 14 is set in a wedge shape to facilitate scraping off excess concrete mortar from the scraper 12. Several second elastic rods 32 are fixedly connected between the lower end of the limiting member 29 and the cleaning plate 14. Magnetic suction rods 25 are fixedly installed at both ends of the cleaning plate 14. The end of each first straight groove 16 is connected to a magnetic suction groove 20 for limiting the magnetic suction rod 25. A magnetic block 23 for generating magnetic attraction force on the magnetic suction rod 25 is fixedly installed at the head end of each magnetic suction groove 20. The magnetic attraction force of the magnetic block 23 on the magnetic suction rod 25 is greater than the elastic force of the second elastic rods 32. Each magnetic suction groove 20 has a second straight groove 22 at its end, and each second straight groove 22 has a second telescopic groove 21 at its end. Each second telescopic groove 21 is connected to a corresponding first straight groove 16. The magnetic suction rod 25 is located in the second straight groove 22, and the upper end of the cleaning plate 14 is above the concrete mortar. In the initial state, the second elastic rod 32 is in a contracted state, and the cleaning plate 14 is located at the end of the second straight groove 22. During the forward movement of the limiting member 29, the cleaning plate 14 will move along the second straight groove 22 towards the end of the magnetic suction groove 20. Since the magnetic suction rod 25 is located in the second straight groove 22 and the upper end of the cleaning plate 14 is above the concrete mortar, the cleaning plate 14 will not affect the filling process of the filling plate 13. Upon reaching the first end of the second straight groove 22, the magnetic suction rod 25 is attracted by the magnetic force of the magnetic block 23. Since the magnetic force of the magnetic block 23 on the magnetic suction rod 25 is greater than the elastic force of the second elastic rod 32, the magnetic suction rod 25 will move downwards along the magnetic groove 20 to the end of the first straight groove 16, stretching the second elastic rod 32. Simultaneously, as the magnetic suction rod 25 moves to the first end of the second straight groove 22, the cleaning plate 14 will adhere to one side of the scraper 12. During its downward movement, the cleaning plate 14 will scrape away the concrete mortar adhering to the scraper 12. After the cleaning plate 14 has finished moving downwards, its lower end will be slightly higher than the lower end of the scraper 12. When the limiting member 29 moves in the opposite direction, it will drive the cleaning plate 14 towards the end of the first straight groove 16, and scrape away the concrete mortar adhering to the scraper 12. Excess concrete mortar accumulated on the movement trajectory of scraper 12 is scraped off. At this time, the lower end of the filler plate 13 is above the concrete mortar and moves towards the beginning of the first straight groove 16 without affecting the scraper 12. When the limiter 29 finishes moving in the opposite direction, the magnetic suction rod 25 will move to the connection between the second telescopic groove 21 and the first straight groove 16. Pulled by the elastic force of the second elastic rod 32, the cleaning plate 14 will drive the magnetic suction rod 25 to move upward to the end of the second straight groove 22. With the reciprocating movement of the limiter 29, the cleaning plate 14 will continuously repeat the above steps to continuously scrape off the concrete mortar adhering to the scraper 12 and scrape off the excess concrete mortar accumulated on one side of the scraper 12, thereby improving the scraping effect of the scraper 12.

[0035] Specifically, first, the support 1 is stopped in a suitable position, the electric telescopic rod 2 is extended, the laser leveler 5 controls the cylinder 4 to work, so that the lowest point of the spiral auger 9's movement trajectory is at a predetermined height, along with the lower end of the vibrating plate 7 and the lower end of the scraper 12. The electric telescopic rod 2 retracts, the scraper 12 performs an initial scraping of excess concrete mortar, the motor 10 drives the spiral auger 9 to rotate, and the spiral auger 9 performs a second leveling of the concrete mortar surface. Excess concrete mortar is discharged to the unleveled area along the rotation direction of the spiral auger 9. Finally, the vibration motor 8 drives the vibrating plate 7 to perform rapid, small-amplitude vibrations, making the concrete mortar surface even smoother. During the extension process of the electric telescopic rod 2, the rotating cylinder 34 is pulled out from the sleeve 33, and the rotating rod 35 also moves from the rotating cylinder 34 to the sleeve 33. The cylinder 34 is pulled out; through the cooperation of the threaded groove 37 and the threaded strip 36, the rotating rod 35 rotates. Since the electric telescopic rod 2 does not require leveling during extension, the cylinder 4 retracts, the distance between the device chamber 26 and the electric telescopic rod 2 is relatively close, the transmission belt 40 is not straightened, and the friction between the transmission belt 40 and the transmission wheel 39 is small, so no transmission occurs; when the electric telescopic rod 2 retracts, the cylinder 4 works, so that the distance between the device chamber 26 and the electric telescopic rod 2 reaches a certain distance, the transmission belt 40 is straightened, and the friction between the transmission belt 40 and the transmission wheel 39 is sufficient for transmission. As the electric telescopic rod 2 retracts, the rotating cylinder 34 moves into the sleeve 33, and the rotating rod 35 also moves into the rotating cylinder 34. The rotating rod 35 rotates again, driving the rotating shaft 27 to rotate. The cooperation between the reciprocating screw groove 28 and the limiting block 30, and the limiting of the limiting member 29 by the guide groove 38, cause the limiting member 29 to continuously slide back and forth along the guide groove 38 when the electric telescopic rod 2 retracts; in the initial state, the first elastic rod 31 is in a compressed state, and the filling plate 13 is located at the beginning of the inclined groove 18. When the limiting member 29 moves in the forward direction, it will drive the filling plate 13 to move obliquely upward along the inclined groove 18; since the telescopic column 24 is located in the inclined groove 18, and the lower end of the filling plate 13 is located in the concrete mortar, the filling plate 13 scrapes up the unleveled concrete mortar during its movement along the inclined groove 18 and fills it onto the movement trajectory of the scraper 12, so that there is sufficient concrete mortar on the movement trajectory of the scraper 12; the filling plate 13 moves to the inclined groove 18. When the telescopic column 24 reaches the end of the groove 18, it is compressed by the inclined surface of the guide block 19. After the telescopic column 24 enters the first straight groove 16, its own elasticity causes it to extend and return to its original position. At this time, the lower end of the filling plate 13 will move to the top of the concrete mortar. The limiting member 29 moves in the opposite direction. The telescopic column 24 is limited by the straight surface of the guide block 19 and moves along the first straight groove 16. At this time, the first elastic rod 31 is always in a compressed state, and the lower end of the filling plate 13 will not contact the concrete mortar. After the telescopic column 24 moves to the beginning of the first straight groove 16, the filling plate 13 is again subjected to the elastic force of the first elastic rod 31 and moves downward along the first telescopic groove 17 and inserts into the concrete mortar. As the limiting member 29 moves back and forth, it continuously fills the scraper 12 along its movement trajectory.Initially, the second elastic rod 32 is in a contracted state, and the cleaning plate 14 is located at the end of the second straight groove 22. During the forward movement of the limiting member 29, the cleaning plate 14 will move along the second straight groove 22 towards the end of the magnetic suction groove 20. Since the magnetic suction rod 25 is located in the second straight groove 22 and the upper end of the cleaning plate 14 is above the concrete mortar, the cleaning plate 14 will not affect the filling plate 13 during the filling process. After the magnetic suction rod 25 moves to the beginning of the second straight groove 22, it will be attracted by the magnetic force of the magnetic block 23. Since the magnetic attraction force of the magnetic block 23 on the magnetic suction rod 25 is greater than the elastic force of the second elastic rod 32, the magnetic suction rod 25 will move down along the magnetic suction groove 20 to the end of the first straight groove 16, causing the second elastic rod 32 to be stretched. At the same time, when the magnetic suction rod 25 moves to the beginning of the second straight groove 22, the cleaning plate 14 will stick to one side of the scraper 12. During the downward movement of the cleaning plate 14, it cleans the concrete mortar adhering to the scraper 12. After the cleaning plate 14 has moved downwards, its lower end will be slightly higher than the lower end of the scraper 12. When the limiting member 29 moves in the opposite direction, it will drive the cleaning plate 14 to move towards the end of the first straight groove 16 and scrape off the excess concrete mortar accumulated on the movement trajectory of the scraper 12. At this time, the lower end of the filler plate 13 is above the concrete mortar and moves towards the beginning of the first straight groove 16 without affecting the scraper 12. When the limiting member 29 finishes moving in the opposite direction, the magnetic suction rod 25 will move to the connection between the second telescopic groove 21 and the first straight groove 16. Pulled by the elastic force of the second elastic rod 32, the cleaning plate 14 will drive the magnetic suction rod 25 upwards to the end of the second straight groove 22. With the reciprocating movement of the limiting member 29, the cleaning plate 14 will continuously repeat the above steps, continuously scraping off the concrete mortar adhering to the scraper 12 and scraping off the excess concrete mortar accumulated on one side of the scraper 12, thus improving the leveling effect of the scraper 12.
