Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a steel belt anti-deviation device for elevators. Background Art

[0002] The main function of the elevator's traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of a traction machine, traction line, guide wheel, and anti-rope wheel. The traction line includes a steel wire rope and a steel belt. Compared with traditional steel wire ropes, steel belts have a longer lifespan, which is 2-3 times that of steel wire ropes; they are lighter, about 20% lighter than traditional steel wire ropes; they are more durable and safer. Each composite steel belt can withstand a tensile force of 3200 kg / 6400 kg, and each elevator has at least 3 composite steel belts.

[0003] In the prior art, the elevator steel is often limited by both sides of the inner wall of the guide wheel to prevent it from running off the track. However, the steel belt will abut against the inner wall of the guide wheel during movement, thereby causing serious friction with the inner wall of the guide wheel, which can easily damage the steel belt and affect the safe operation of the elevator. Therefore, it is necessary to propose an elevator steel belt anti-deviation device to solve the above-mentioned problem. Utility Model Content
