Detailed Implementation

[0020] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1-4 As shown, this embodiment proposes a solution: an elevator telescopic door guide rail groove cleaning device, including a fixed base 1, a fixed block fixedly installed on the left side near the top of the fixed base 1, a lifting base 2 slidably connected to the inside of the fixed base 1, an electric telescopic rod 3 for driving the lifting base 2 fixedly installed at the bottom of the fixed block, a bidirectional threaded screw 4 rotatably connected to the inside of the lifting base 2, a movable frame 5 sleeved on the surface of the bidirectional threaded screw 4 near the left and right ends and threadedly connected to it, a drive motor 6 for driving the bidirectional threaded screw 4 to rotate fixedly installed on the left side of the lifting base 2, a scraper 7 slidably connected to the inside of the movable frame 5 near the bottom, a dust suction assembly provided on the top of the lifting base 2 for dust suction inside the guide rail groove, and a drive assembly provided on the inside of the movable frame 5 for driving the scraper 7 to slide left and right to clean dust.

[0022] In this embodiment, during the use of the device, the scraper 7 is aligned with the top of the guide rail groove to be cleaned, and the electric telescopic rod 3 starts working, driving the lifting seat 2 to move downwards until the scraper 7 below the lifting seat 2 is precisely aligned with the cleaning area of ​​the guide rail groove, realizing flexible adjustment of the cleaning height. After the drive motor 6 starts, it will drive the bidirectional threaded screw 4 connected to its output end to rotate inside the lifting seat 2. Since the moving frame 5 is sleeved on the surface of the bidirectional threaded screw 4 and meshes with the thread, the two moving frames 5 drive the scraper 7 and the dust collection component to move towards the center. The scraper 7 driven by the drive component reciprocates to clean the stubborn dust at the bottom of the inner side of the guide rail groove. With the help of the dust collection component, the dust and fine particles inside the guide rail groove are vacuumed. When the two scraper 7 come together, they clamp larger debris or particles, and then the electric telescopic rod 3 drives the scraper 7 to move upwards, making it easier for the staff to clean the clamped debris or particles, saving time and effort, and making it easier for the staff to clean the inner side of the guide rail groove.

[0023] The vacuuming assembly includes a vacuum box 8, with vacuum pumps 9 fixedly installed on the left and right sides of the vacuum box 8. A vacuum pipe 10 is fixedly installed on the side of the vacuum pump 9 away from the vacuum box 8, and a vacuum hood 11 is fixedly installed on the end of the vacuum pipe 10 away from the vacuum pump 9. The side wall of the vacuum hood 11 is fixedly connected to the surface of the adjacent scraper 7. While the scraper 7 is cleaning dirt, the vacuum pumps 9 on both sides of the vacuum box 8 at the top of the lifting seat 2 are activated, generating negative pressure through the vacuum pipe 10, so that the vacuum hood 11 can suck up the scraped dust and debris in time.

[0024] The lifting seat 2 has a connecting hole on its inner side for the vacuum pipe 10 to pass through. The vacuum box 8 has a collection box that is slidably connected to the front side near the bottom. The collection box collects dust and debris, which is convenient for staff to clean up later.

[0025] The drive assembly includes a rotating shaft 12, with a rotating gear 13 fixedly mounted on the surface of the rotating shaft 12 near its rear end. A rack 14, meshing with the rotating gear 13, is fixedly mounted on the inner side of the lifting seat 2 and at the bottom of the bidirectional threaded screw 4. A cam 15 is fixedly mounted on the surface of the rotating shaft 12 and on one side of the scraper 7. Two movable rods 16 are fixedly mounted on the side of the scraper 7 away from the cam 15. The movable rods 16 pass through the inner side of the movable frame 5 and are slidably connected thereto. A drive mechanism is provided on the inner wall of the movable frame 5 at the outer edge of the movable rods 16. When the moving frame 5 moves, the rotating gear 13 on the inner rotating shaft 12 of the movable scraper 7 will mesh with the rack 14 fixed on the inner side of the lifting seat 2. The rack 14 will generate a reaction force on the rotating gear 13, causing the rotating gear 13 to drive the rotating shaft 12 to rotate. When the cam 15 on the surface of the rotating shaft 12 rotates with the shaft, it will periodically squeeze the scraper 7. With the action of the spring 17 and the movable rod 16, the scraper 7 will move back and forth to scrape away the stubborn dirt at the bottom of the guide rail groove, thus enhancing the cleaning effect of the device.

[0026] The inner side of the movable frame 5 has a notch for the rack 14 to move left and right, a rotating opening for the rotating gear 13 and cam 15 to rotate, and a moving groove for the scraper 7 to slide left and right. The moving groove increases the stability of the scraper 7 moving left and right.

[0027] The fixed base 1 has two support legs 18 fixedly installed on the front and rear sides. The fixed base 1 has a lifting port 19 on the inner side for the lifting base 2 to slide up and down. The fixed base 1 has a heat dissipation port on the top. The lifting port 19 increases the stability of the lifting base 2 when it moves up and down.

[0028] The above embodiment discloses a cleaning device for elevator telescopic door guide rail grooves. During use, the scraper 7 is aligned with the top of the guide rail groove to be cleaned, and the electric telescopic rod 3 starts working, driving the lifting seat 2 downwards until the scraper 7 below the lifting seat 2 is precisely aligned with the cleaning area of ​​the guide rail groove, achieving flexible adjustment of the cleaning height. After the drive motor 6 starts, it drives the bidirectional threaded screw 4 connected to its output end to rotate inside the lifting seat 2. Since the moving frame 5 is sleeved on the surface of the bidirectional threaded screw 4 and meshes with the thread, the two moving frames 5 drive the scraper 7 and the dust collection assembly to move towards the center. When the moving frame 5 moves, the rotating gear 13 on its inner rotating shaft 12 meshes with the rack 14 fixed inside the lifting seat 2, and the rack 14 generates a reaction force on the rotating gear 13. The rotating gear 13 drives the rotating shaft 12 to rotate. When the cam 15 on the surface of the rotating shaft 12 rotates with the shaft, it periodically squeezes the scraper 7. With the action of the spring 17 and the movable rod 16, the scraper 7 moves back and forth to scrape away stubborn dirt at the bottom of the guide rail groove, enhancing the cleaning effect of the device. While the scraper 7 is cleaning the dirt, the vacuum pumps 9 on both sides of the vacuum box 8 on the top of the lifting seat 2 are started. The vacuum pipe 10 generates negative pressure, which causes the vacuum hood 11 to suck up the scraped dust and debris in time. When the two scrapers 7 come together, they clamp larger debris or particles. The electric telescopic rod 3 drives the scraper 7 to move upward, which makes it easier for the staff to clean the clamped debris or particles, saving time and effort. This also makes it easier for the staff to clean the inside of the guide rail groove.
