[0002] Elevator guide rails are key guiding components for elevator operation, and their surface quality directly impacts the safety and comfort of elevator operation. Over long-term use, elevator guide rails are exposed to the humid hoistway environment and corroded by dust and impurities within the hoistway, causing their surfaces to rust. Therefore, regular rust removal is necessary.

[0003] At present, the rust removal method of elevator guide rails mainly relies on manual grinding, using tools such as sandpaper and grinding wheels. During grinding, the grinding force is completely controlled by the strength of the arms. Due to different arm forces during grinding, the surface of the elevator guide rails may be uneven, affecting the smooth operation of the elevator car. At the same time, the rust dust generated by manual grinding is easy to spread in the shaft, causing harm to the health of the operators and may also contaminate other parts of the elevator. Therefore, a surface rust removal device for elevator guide rails is proposed. Utility Model Content

Through mechanical drive, the force applied during the grinding process can be made more uniform, thereby avoiding unevenness on the surface of the elevator guide rail. The arrangement of the dust suction mechanism can collect the rust removed by the grinding mechanism to avoid it from spreading in the hoistway, making the device more convenient to use.

[0023] In this embodiment, after the device is placed in the elevator shaft and the climbing wheel 15 is aligned with the elevator guide rail 4, the first cylinder 13 is started to push the first mounting member 14 to drive the climbing wheel close to the elevator guide rail 4, so that the inner wall of the climbing wheel 15 is in close contact with the surface of the elevator guide rail 4. Subsequently, the first motor 17 is started to drive the climbing wheel 15 to rotate, so that the device can climb upward along the elevator guide rail 4. At the same time, the provision of the hard rubber layer 16 can increase the friction between the climbing wheel 15 and the elevator guide rail 4, so that the device can climb stably.

[0024] Example 2

[0025] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the rust removal mechanism includes a second mounting member 21, one side of the second mounting member 21 is fixedly connected to the second cylinder 22, the output end of the second cylinder 22 is fixedly connected to the connecting plate 23, the inner wall of the connecting plate 23 is fixedly connected to the second motor 24, one end of the rotating shaft of the second motor 24 is fixedly connected to the grinding disc 25, the surface of the rotating shaft of the second motor 24 is plugged into the interior of the second mounting member 21, and the two ends of the second mounting member 21 are fixedly connected to the surface of the first mounting member 14.

[0026] In this embodiment, by starting the second cylinder 22, it drives the second motor 24 to move through the connecting plate 23, and then the grinding sheet 25 is brought close to the surface of the elevator guide rail 4. Under the action of the second motor 24, the grinding sheet 25 is driven to grind the surface of the elevator guide rail 4.
