Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] Example 1 Reference Figure 1-4 This utility model embodiment proposes an elevator door panel surface grinding and cleaning device, including a support component 1, a grinding component one 2 and a grinding component two 3. An elevator door frame 4 and an elevator door panel 5 are provided on the outside of the support component 1. The elevator door frame 4 is located on one side of the elevator door panel 5. The elevator door frame 4 and the elevator door panel 5 can form a protective structure to prevent people from falling into the elevator shaft. The support assembly 1 includes a fixed platform 11. An air chamber 111 is located at the center of the fixed platform 11, and an air pump 12 is located at the center of one outer wall of the fixed platform 11. The output end of the air pump 12 is connected to the air chamber 111. Four rod sleeves 13 are symmetrically arranged on the outer wall of the fixed platform 11. A piston chamber 131 is located inside each rod sleeve 13. A limit block 132 is located on the inner wall of the piston chamber 131. A circular hole is located on one outer wall of the limit block 132. Both the air chamber 111 and the piston chamber 131 are connected to the circular hole, allowing for gas flow. This allows gas to flow between the gas chamber 111 and the piston chamber 131. The air pressure can push the piston rod 14 to move. A spring 133 is provided on one side of the outer wall of the limiting block 132. A piston rod 14 is provided at one end of the spring 133. The piston rod 14 makes a piston-like movement inside the rod sleeve 13. The piston-like movement can ensure the stability and sealing of the piston rod 14 inside the rod sleeve 13. A rotating rod 15 is rotatably connected to one end of the piston rod 14. An angle iron block 16 is rotatably connected to one end of the rotating rod 15. The adjacent two side walls of the angle iron block 16 are perpendicular to each other, and the angle iron block 16 abuts against the corner of the inner side wall of the elevator door frame 4. The right angle side of the angle iron block 16 can be used to make the angle iron block 16 fit against the inner side of the elevator door frame 4, thereby forming a support. A screw rod 17 is screwed into one side of the outer wall of the fixed platform 11. A grinding component 2 is provided at one end of the screw rod 17. Specifically, to alleviate the laborious problem of manually holding grinding tools, this embodiment utilizes a support component 1 to support the grinding tool. When setting up the support component 1, it is placed inside the elevator door frame 4, and the fixed platform 11 is parallel to the elevator door panel 5. At this time, the air pump 12 is controlled to draw air into the air chamber 111. Under the connection, the gas in the air chamber 111 passes through the limiting block 132 and enters the piston chamber 131. The air pressure in the piston chamber 131 increases. Under the push of the air pressure, the gas pushes the piston rod 14 in the sleeve 13 out. After the piston rod 14 is pushed out, the rotating rod 15 at one end of the piston rod 14 and the angle iron block 16 move synchronously. As the angle iron block 16 moves, it is until it fits against the corner of the elevator door frame 4. Through the support formed by the four angle iron blocks 16, the support component 1 can be fixed inside the elevator door frame 4. The support component 1 provides support and position for the installation of the grinding tool.
[0019] The grinding assembly 2 includes a Y-axis moving platform 21 that rotates at one end of the screw 17. A guide post 18 is provided on one outer wall of the Y-axis moving platform 21, and an X-axis moving platform 22 is provided at the output end of the Y-axis moving platform 21. A moving plate 23 is provided at the output end of the X-axis moving platform 22. A dual-axis motor 24 is provided on one outer wall of the moving plate 23, and grinding rollers 25 are provided at both output ends of the dual-axis motor 24. Specifically, in order to achieve the grinding and cleaning of the elevator door panel 5, the Y-axis moving platform 21 is first installed on the fixed platform 11 of the support component 1, so that the grinding roller 25 is pressed against the outer wall of the elevator door panel 5. The Y-axis moving platform 21 drives the X-axis moving platform 22 to move vertically and vertically through its output end. The X-axis moving platform 22 drives the moving plate 23 to move horizontally through its output end. At this time, the dual-axis motor 24 on the moving plate 23 moves synchronously, and the grinding roller 25 can move vertically and vertically along the elevator door panel 5, and gradually adjust the horizontal position of the grinding roller 25 so that the grinding roller 25 can grind and clean the elevator door panel 5 from all directions. During the grinding operation, the dual-axis motor 24 is controlled to drive the two grinding rollers 25 to rotate at high speed through its output end. The grinding rollers 25 grind and clean the elevator door panel 5 without manual handling, saving time and effort.
[0020] Example 2 Reference Figure 2 and Figure 4 Based on the above embodiments, this utility model embodiment also proposes an elevator door panel surface grinding and cleaning device. The grinding component 2 3 includes a docking plate 31 disposed on the outer wall of the movable plate 23. A docking frame 32 is fixedly connected to the docking plate 31 by bolts. A fixing plate 33 is disposed on one outer wall of the docking frame 32. An electric push rod 34 is disposed on one outer wall of the fixing plate 33. A slider 35 is fixedly connected to the electric push rod 34 through its output end. The slider 35 passes through the docking frame 32 and slides with it, which can ensure the stability of the slider 35 and the grinding block 36 moving on the docking frame 32. A grinding block 36 is disposed on one outer wall of the slider 35.
[0021] Specifically, in order to grind and clean the corners of the elevator door panel 5, the docking plate 31 and docking bracket 32 are installed on the moving plate 23. The grinding component 3 is moved by the Y-axis moving platform 21 and the X-axis moving platform 22, so that the grinding blocks 36 on the grinding component 3 contact the four corners of the elevator door panel 5. Then, the electric push rod 34 is controlled to drive the slider 35 to move horizontally and linearly through its output end. The grinding blocks 36 on the slider 35 move synchronously. The grinding blocks 36 grind the corners of the elevator door panel 5, realizing a comprehensive cleaning of the elevator door panel 5 and effectively removing rust, stains and stickers on the elevator door panel 5.
