Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for elevator guide rails. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator. Therefore, the guide rails should be selected according to the elevator speed and load. The car guide rails are usually called the main rails, and the counterweight guide rails are called the auxiliary rails. After the elevator guide rails are processed, the outer surface of the elevator guide rails needs to be polished and rust-removed.

[0003] An existing elevator guide rail rust removal device (publication number: CN219380257U) has at least the following disadvantages:

[0004] When in use, the grinding device is manually pushed to slide along the outer surface of the guide rail, so that the grinding frame and the grinding roller remove rust and grind the outer surface of the guide rail. Due to the long length of the elevator guide rail, the rust removal and grinding are performed by manually pushing the device, which increases the labor intensity of the operator and affects the efficiency of grinding and rust removal.

[0024] The third pulley 11 is driven to rotate by the U-shaped grinding wheel 5, and the third pulley 11 drives the fourth pulley 13 to rotate through the second belt 12, so that the fourth pulley 13 drives the rubber wheel 4 to rotate, and the rotation of the rubber wheel 4 drives the device to move along the outer surface of the elevator guide rail 2, so that the device can continuously grind and remove rust on the outer surface of the elevator guide rail 2, which greatly reduces the labor intensity of users and improves the efficiency of grinding and rust removal.

[0025] In this embodiment, a U-shaped groove is provided on the circumferential outer surface of the U-shaped grinding wheel 5, and the U-shaped groove is abutted against the upper surface of the elevator guide rail 2. A U-shaped groove is provided on the circumferential outer surface of the U-shaped grinding wheel 5, and the U-shaped groove is abutted against the upper surface of the elevator guide rail 2. The outer surface of the grinding roller 6 away from the elevator guide rail 2 is fixedly installed with a second pulley 9, and the outer surfaces of both ends of the U-shaped grinding wheel 5 are fixedly installed with a first pulley 7, and the outer surfaces of the first pulley 7 and the second pulley 9 are sleeved with a first belt 8.

[0026] During use, the user inserts the elevator guide rail 2 between the rubber wheel 4 and the baffle 3.

The U-shaped grinding wheel 5 is driven by the driving motor 10 to rotate, so that the U-shaped grinding wheel 5 grinds and removes rust on the upper surface and the arc surface of the elevator guide rail 2. At the same time, the U-shaped grinding wheel 5 drives the first pulley 7 to rotate, and the first pulley 7 drives the second pulley 9 to rotate through the first belt 8, so that the second pulley 9 drives the grinding roller 6 to rotate. The grinding roller 6 grinds and removes rust on the outer surface of the elevator guide rail 2.
