Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flatness control, in particular to a flatness control mechanism for factory floor construction. BACKGROUND

[0002] In the process of factory floor construction, due to various factors such as material performance, construction technology and environmental factors, the flatness of the floor may deviate, and the flatness of the factory floor as the basis for equipment operation has an important influence on the stability, precision and life of the equipment. Uneven floor can cause vibration, deviation and wear of the equipment during operation, and in severe cases, it may even cause safety accidents. In addition, the floor needs to bear the load of various heavy equipment and goods, as well as frequent vehicle and personnel traffic. Flatness control is a crucial link in the process of factory floor construction and is directly related to the use effect and durability of the floor. The flatness requirement mainly reflects the uniformity and smoothness of the floor surface. Through reasonable construction methods and material selection, the floor surface is ensured to be free of obvious concave-convex and cracks.

[0003] The existing factory floor flatness control mechanism usually uses a more advanced laser leveling machine to replace traditional instruments. The laser leveling machine uses a hydraulic device to drive the leveling head, cooperates with a laser system and a computer control system, and completes the leveling work while automatically leveling. During the operation of the leveling head, manual workers are needed to continuously fill concrete materials to the leveling route for pre-paving, because there may be gaps or unevenness in the process of laying concrete. If pre-paving is not performed, defects may occur in the leveled floor. When manually pre-paving concrete materials, it may not be consistent with the machine leveling speed, or even there may be too much or too little filling of concrete materials, affecting the flatness control of the leveling head on the floor. Therefore, we propose a flatness control mechanism for factory floor construction. SUMMARY

[0023] The cleaning plate 14 is slidably arranged between the two limiting plates 15 and is used to scrape the excess concrete mortar on the scraper 12. The cleaning plate 14 is also arranged in a V shape corresponding to the scraper 12. The lower end of the cleaning plate 14 is arranged in a wedge shape to facilitate scraping the excess concrete mortar on the scraper 12. A plurality of second elastic rods 32 are fixedly connected between the lower end of the limiting member 29 and the cleaning plate 14. The magnetic attraction rods 25 are fixedly arranged at the two ends of the cleaning plate 14. The end of each first straight slot 16 is communicated with a magnetic attraction slot 20 used to limit the magnetic attraction rod 25. The front end of each magnetic attraction slot 20 is fixedly provided with a magnetic block 23 used to generate a magnetic attraction force on the magnetic attraction rod 25. The magnetic attraction force of the magnetic block 23 on the magnetic attraction rod 25 is greater than the elastic force of the second elastic rod 32. The end of each magnetic attraction slot 20 is communicated with a second straight slot 22. The end of each second straight slot 22 is communicated with a second telescopic slot 21. Each second telescopic slot 21 is communicated with the corresponding first straight slot 16. The magnetic attraction rod 25 is located in the second straight slot 22, and the upper end of the cleaning plate 14 is located above the concrete mortar. In the initial state, the second elastic rod 32 is in the contracted state, and the cleaning plate 14 is located at the end of the second straight slot 22. During the forward movement of the limiting member 29, the cleaning plate 14 is driven to move along the second straight slot 22 to the end of the magnetic attraction slot 20. Since the magnetic attraction rod 25 is located in the second straight slot 22, and the upper end of the cleaning plate 14 is located above the concrete mortar, the cleaning plate 14 does not affect the filling plate 13 during the filling process. After the magnetic attraction rod 25 moves to the front end of the second straight slot 22, it is attracted by the magnetic force of the magnetic block 23. Since the magnetic attraction force of the magnetic block 23 on the magnetic attraction rod 25 is greater than the elastic force of the second elastic rod 32, the magnetic attraction rod 25 will move downward along the magnetic attraction slot 20 to the end of the first straight slot 16, so that the second elastic rod 32 is stretched. At the same time, when the magnetic attraction rod 25 moves to the front end of the second straight slot 22, the cleaning plate 14 will be attached to one side of the scraper 12. During the downward movement of the cleaning plate 14, the concrete mortar adhered to the scraper 12 will be scraped. After the downward movement of the cleaning plate 14 is completed, the lower end of the cleaning plate 14 will be slightly higher than the lower end of the scraper 12. When the limiting member 29 moves in the reverse direction, the cleaning plate 14 will move to the end of the first straight slot 16, and the excess concrete mortar accumulated on the movement track of the scraper 12 will be scraped. At this time, the lower end of the filling plate 13 is located above the concrete mortar and moves to the front end of the first straight slot 16, and does not affect the scraper 12. When the limiting member 29 completes the reverse movement, the magnetic attraction rod 25 will move to the position where the second telescopic slot 21 is communicated with the first straight slot 16, and will be pulled upward by the elastic force of the second elastic rod 32 to the end of the second straight slot 22. With the reciprocating movement of the limiting member 29, the cleaning plate 14 will continuously repeat the above steps, continuously scrape the concrete mortar adhered to the scraper 12, and continuously scrape the excess concrete mortar accumulated on one side of the scraper 12, thereby improving the scraping effect of the scraper 12.

During the forward movement of the limiting piece 29, the cleaning plate 14 is driven to move along the second straight groove 22 to the end of the magnetic attraction groove 20. Since the magnetic attraction rod 25 is located in the second straight groove 22, and the upper end of the cleaning plate 14 is located above the concrete mortar, the cleaning plate 14 will not affect the filling plate 13 during the filling process of the filling plate 13. After the magnetic attraction rod 25 moves to the first end 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 attraction rod 25 is greater than the elastic force of the second elastic rod 32, the magnetic attraction rod 25 will move downward along the magnetic attraction groove 20 to the end of the first straight groove 16, so that the second elastic rod 32 is stretched. At the same time, when the magnetic attraction rod 25 moves to the first end of the second straight groove 22, the cleaning plate 14 will be attached to one side of the scraper 12. During the downward movement of the cleaning plate 14, the concrete mortar adhered to the scraper 12 is scraped off. After the downward movement of the cleaning plate 14 is completed, the lower end of the cleaning plate 14 is slightly higher than the lower end of the scraper 12. When the limiting piece 29 moves in the reverse direction, the cleaning plate 14 will move to the end of the first straight groove 16, and the excess concrete mortar accumulated on the movement track of the scraper 12 will be scraped off. At this time, the lower end of the filling plate 13 is located above the concrete mortar, and moves to the first end of the first straight groove 16, and will not affect the scraper 12. When the limiting piece 29 moves in the reverse direction, the magnetic attraction rod 25 will move to the position where the second telescopic groove 21 communicates with the first straight groove 16, and will be pulled upward by the elastic force of the second elastic rod 32. The cleaning plate 14 will drive the magnetic attraction rod 25 to move upward to the end of the second straight groove 22, and will repeatedly perform the above steps with the reciprocating movement of the limiting piece 29.
