Description

Technical Field

[0001] The utility model relates to the technical field of elevator accompanying cables, in particular to a limiting mechanism for elevator accompanying flat cables. Background Art

[0002] The limiting mechanism of the elevator's traveling cable is mainly used to limit the movement range of the traveling cable during the operation of the elevator, to prevent the cable from rubbing against other components in the elevator shaft due to shaking or deviation, thereby ensuring the safe operation of the elevator.

[0004] The existing public technical solution, with announcement number CN207759871U, discloses a position-limiting fixed bracket for elevator traveling cables, including a position-limiting groove body fixedly arranged in the vertical direction of the elevator shaft bracket, a fixed bracket arranged in the position-limiting groove body, and the fixed bracket including a fixed cover and a position-limiting mechanism placed in the fixed cover; the position-limiting plate moves up and down under the drive of the telescopic rod and forms a position-limiting space for the traveling cable between the fixed cover and the fixed cover. The traveling cable is position-limited and fixed on the shaft bracket by the fixed bracket, and with the operation of the elevator, it can be position-limited in the horizontal direction according to the wind speed in the elevator shaft, so that the traveling cable moves up and down in the position-limiting fixed bracket, limiting its left and right shaking, and avoiding the occurrence of scratches caused by the shaking of the cable.

[0005] When the above technical solution is actually implemented, the limiting mechanism in the fixed cover will be driven by a motor to reduce the limiting space of the accompanying cable formed by the fixed cover and the limiting plate. The limiting plate is in direct contact with the accompanying cable, which will cause the accompanying cable to repeatedly rub against the limiting plate when moving, thereby causing wear of the accompanying cable.
