Description

Technical Field

[0001] This utility model relates to the field of municipal building technology, and in particular to a safety modification device for the maintenance of square columns in municipal buildings. Background Technology

[0002] In municipal construction, square columns are often used to prevent vehicles from entering or for decoration. However, due to their square structure and sharp edges, these columns can easily cause scratches to pedestrians. Therefore, safety modifications are necessary. In conventional operations, workers use modification parts to smooth the edges of the columns and add splash guards to shield the columns during grinding, preventing debris from flying outwards and injuring workers. However, existing splash guards lack top and bottom plates, so debris may still fly upwards during grinding, limiting safety during the modification process. Furthermore, the debris falls to the ground, requiring workers to clean up the site, which affects the overall efficiency of the square column modification.

[0003] To address the aforementioned issues, a safety modification device for the maintenance of square columns in municipal buildings has been developed. Utility Model Content

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] Example 1 A safety modification device for the maintenance of square columns in municipal buildings, such as Figures 1-3 As shown, the device includes a mounting frame 1 with a pair of handrails. Self-locking wheels 2 are rotatably connected to the four corners of the lower part of the mounting frame 1. A first drive assembly 3 is mounted on the upper left side of the mounting frame 1, including a first drive motor and a screw. The first drive motor is mounted on the upper left side of the mounting frame 1, and a screw is connected to the output shaft of the first drive motor, rotatably connected to the mounting frame 1. A connecting frame 4 is threaded onto the screw, slidably connected to the mounting frame 1. A second drive assembly 5 is mounted on the connecting frame 4, including a second drive motor and a gear. The second drive motor is mounted on the connecting frame 4, and a gear is connected to the output shaft of the second drive motor, rotatably connected to the connecting frame 4. A modification component 6 is rotatably connected to the left side of the connecting frame 4, with the outer side of the modification component 6 meshing with the gear. A positioner 7 is mounted on the lower side of the connecting frame 4, and a splash-proof mechanism 8 is provided on the right side of the mounting frame 1.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, the splash-proof mechanism 8 includes a dual-axis lead screw motor 81. The dual-axis lead screw motor 81 is mounted on the upper left side of the mounting bracket 1. The dual-axis lead screw motor 81 includes a dual-axis motor, a front lead screw, and a rear lead screw. The dual-axis motor is mounted on the mounting bracket 1. The front lead screw is connected to the front output shaft of the dual-axis motor, and the rear lead screw is connected to the rear output shaft of the dual-axis motor. Both the front lead screw and the rear lead screw are threadedly connected to splash-proof frames 82. The bottom of each splash-proof frame 82 is provided with a base plate. The top plate 83 is connected to the connecting bracket 4. Three ball bearings 84 are rotatably connected to the lower side of each splash-proof frame 82.

[0023] It should be noted that in municipal construction, square columns are often used to prevent vehicles from entering or for decoration. Because of their square structure and sharp edges, these columns can easily cause scratches to pedestrians. Therefore, safety modifications are necessary. Operators use handrails to move the device to a suitable position and lock it using the self-locking wheel 2 to prevent displacement during the column modification. The locator 7 locates the column and triggers the dual-axis lead screw motor 81, causing the splash guard 82 to move inward. The splash guard 82 encloses the column, then the first drive motor is activated, and the first drive motor outputs... The rotation of the output shaft drives the screw to rotate, which in turn drives the connecting frame 4 and the top plate 83 to move. At the same time, the second drive motor is started. The output shaft of the second drive motor rotates, which drives the gear to rotate, which in turn drives the modified component 6 to rotate. The modified component 6 grinds the edge of the square column, transforming the edge of the square column into a polygonal structure, thereby avoiding sharp edge lines that may cause injury to pedestrians. During the grinding process, the splash guard 82 and the top plate 83 can prevent debris from flying outward, which helps to improve the safety of the modification process. At the same time, the debris after grinding will fall to the bottom of the splash guard 82, which makes it easy for operators to quickly clean up the debris, which helps to improve the cleanliness of the construction site and the efficiency of the square column modification.

[0024] Example 2 Based on Example 1, such as Figure 1 and Figure 6 As shown, it also includes an extraction mechanism 9, which includes a vacuum cleaner 91. The vacuum cleaner 91 is mounted on the mounting frame 1. Extraction components 92 are installed between the splash guard 82 and the vacuum cleaner 91. An air vent 93 is connected to the upper part of the vacuum cleaner 91. A dust collection frame 94 is slidably connected to the vacuum cleaner 91. The dust collection frame 94 is provided with a handle.

[0025] It should be noted that, in order to quickly and automatically remove the debris generated during the modification process, the vacuum cleaner 91 can be started. The vacuum cleaner 91 uses the extraction component 92 to extract the debris into the dust collection frame 94, thereby quickly cleaning the debris on the splash guard 82. After the modification is completed, the dust collection frame 94 can be pulled outwards using the handle to collect and dispose of the debris.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
