The invention discloses a swing type steel wire rope rainproof device for a portal crane, and relates to the technical field of portal cranes. The rainproof device comprises a rotating device and a wrapping ring which are arranged on a machine roof, the wrapping ring penetrates through the machine roof, a cover shell is arranged on the rotating device, the wrapping ring is inserted into the cover shell, a steel wire rope penetrates through the wrapping ring and the cover shell, a swing assembly is installed on the cover shell, an outlet device is rotationally connected to the swing assembly, and the outlet device is connected with the machine roof. The outlet device comprises an outlet support and a plurality of idler wheels, the outlet support is rotationally connected with the swing assembly, the idler wheels are rotationally connected to the outlet support, and the steel wire rope is arranged among the idler wheels in a penetrating mode. The steel wire rope can swing freely in the winding process, interference between the steel wire rope and a machine roof can be reduced, friction loss of the steel wire rope and the rainproof device is reduced, and the service life of the steel wire rope and the rainproof device is prolonged.

    本发明公开了一种门座起重机用摇摆式钢丝绳防雨装置,涉及门座起重机的技术领域。该防雨装置包括设于机器房顶上的转动装置和包圈,所述包圈贯穿机器房顶,所述转动装置上设有罩壳,所述包圈插设于罩壳内,钢丝绳穿设于所述包圈和罩壳内,所述罩壳上安装有摆动组件,所述摆动组件上转动连接有出口装置,所述出口装置包括出口支座和若干个滚轮,所述出口支座与摆动组件转动连接,若干个所述滚轮均转动连接在出口支座上,钢丝绳穿设于若干个所述滚轮之间。本申请既可以使得钢丝绳在卷绕过程中自由摇摆,又可以减少钢丝绳与机器房顶的干涉,减少钢丝绳和防雨装置的摩擦损耗,提高钢丝绳和防雨装置的使用寿命。
