[0009] Technical effects and advantages of the utility model:

[0010] 1. The utility model adopts an electric slider and a scraper structure, so that the outer protective layer of the concrete column can be scraped and cleaned, without the need for manual climbing to a high place for operation, thereby improving the safety of the operation. The support plate supports the indoor ceiling to avoid the concrete column from being broken during the scraping process and causing local collapse.

[0011] 2. The utility model adopts a limiting screw structure, which is convenient for replacing the easily worn scraper, and adopts a limiting bolt structure to avoid relative rotation of the limiting screw, thereby improving the stability of the scraper during operation.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] See also Figures 1 to 5In this embodiment, a building concrete column reshaping device is provided, including a base 1 and a scraper 2. The upper end surface of the base 1 is symmetrically provided with a fixing groove, and a first screw 11 is rotatably installed on the inner end of the fixing groove through a bearing. A first slider is screwed on the outer wall of the first screw 11, and a side plate 12 is installed on the upper end surface of the first slider. A connecting frame 13 is installed on the outer end of the side plate 12, and an electric slider 14 is installed on the inner end of the side plate 12. A fixing rod is installed on the inner end of the electric slider 14, and a scraper 2 is installed on the inner end of the fixing rod. A handle 15 is installed on the outer end of the first screw 11. The upper end surface of the base 1 is provided with a fixing hole, and the upper end surface of the side plate 12 is provided with a fixing hole. A support plate 18 is fixedly installed on the end surface, and the electric slider 14 is a linear guide slider structure. The motor drives the lead screw to rotate to control the linear movement of the device. When working, the concrete column is passed through the fixed hole, and the handle 15 is turned to drive the first lead screw 11 to rotate, so that the scraper 2 moves inward and close to the concrete column. The electric slider 14 is started to drive the scraper 2 to move up and down, thereby scraping and cleaning the protective layer of the outer wall of the concrete column. There is no need to manually climb to a high place to perform the operation, which improves the safety of the operation. The support plate 18 supports the indoor ceiling to avoid the concrete column from being broken during the scraping process and causing local collapse.

[0020] The scraper 2 is screwed to the inner end of the fixing rod through a limiting screw 16, and the outer wall of the limiting screw 16 is screwed to a limiting bolt 17. During operation, the limiting screw 16 structure is adopted to facilitate the replacement of the easily worn scraper 2, and the limiting bolt 17 structure is adopted to avoid relative rotation of the limiting screw 16, thereby improving the stability of the scraper 2 during operation.

[0021] The base 1 is connected by two semi-ring plates through a snap-fitting manner. An adjusting plate 19 is rotatably installed on the upper end surface of the base 1 through a bearing. A spring rod 21 is installed at the bottom of the adjusting plate 19. A slot is arranged below the spring rod 21. A top rod 22 is installed at the bottom of the slot through a sliding fit. When working, the semi-ring plate structure is adopted, so that the base 1 can be spliced ​​on the outer wall of the concrete column, and the spring rod 21 is inserted and fixed in the slot, thereby improving the stability of the connection between the semi-ring plates.

[0022] The outer end of the connecting frame 13 is rotatably mounted with an adjusting screw 23 through a bearing, and the outer wall of the adjusting screw 23 is screwed with a pressing plate 24, and the upper end surface of the pressing plate 24 is connected to the top of the connecting frame 13 by a sliding fit. During operation, the adjusting screw 23 rotates to drive the pressing plate 24 to move inward, thereby pressing and fixing the handle 15 to prevent the handle 15 from rotating relative to each other, causing the side plate 12 to move, and further ensuring the stability of the scraper 2.

[0023] During specific work, a semi-ring plate structure is adopted, so that the base 1 can be spliced ​​on the outer wall of the concrete column, and the spring rod 21 is inserted and fixed in the slot, thereby improving the stability of the connection between the semi-ring plates. The handle 15 is turned to drive the first screw 11 to rotate, so that the scraper 2 moves inward and close to the concrete column. The electric slider 14 is started to drive the scraper 2 to move up and down, so as to scrape and clean the protective layer of the outer wall of the concrete column. There is no need to manually climb to a high place to perform the operation, which improves the safety of the operation. The support plate 18 supports the indoor ceiling to avoid the concrete column from being broken during the scraping process and causing local collapse.
