Flaring device for preventing corrosion-resistant protective layer of stay cable from being scraped by cableway pipe orifice
The invention relates to a flaring device for preventing an anticorrosive protective layer of a stay cable from being scraped by a cableway pipe orifice, the flaring device comprises a horn mouth mechanism, the horn mouth mechanism comprises a straight pipe section connected with a cableway pipe and a horn mouth body, a narrow mouth of the horn mouth body is connected with the straight pipe section, and the straight pipe section is connected with the horn mouth body; the central axes of the cableway pipe, the straight pipe section and the horn mouth body coincide. The idler wheel assembly is arranged in the horn mouth body and comprises a plurality of idler wheel bodies which are arranged around the central axis of the horn mouth body at intervals, a circle is defined by all the idler wheel bodies, and in the using process, a stay cable penetrates through the circle defined by the idler wheel bodies and then sequentially stretches into the straight pipe section and the cableway pipe; and the stay cable is in rolling contact with the roller body. Compared with the prior art, the device can prevent a protective layer of the stay cable from being scraped by a cableway pipe opening, meanwhile, it can be guaranteed that the stay cable rapidly penetrates through a cableway pipe, the requirement for the precision of a hoisting point of a crane is not high when the device is used, and operation is easy.
本发明涉及一种用于防止斜拉索防腐保护层被索道管口刮破的扩口装置，该扩口装置包括：喇叭口机构：其包括与索道管连接的直管段、以及喇叭口本体，所述喇叭口本体的窄口与所述直管段连接，所述索道管、直管段和喇叭口本体的中心轴线重合；滚轮组件：其设置在所述喇叭口本体的内部，所述滚轮组件包括围绕喇叭口本体的中心轴线间隔布置的若干个滚轮本体，所有滚轮本体围成一个圆，在使用时，斜拉索穿过滚轮本体围成的圆，然后依次伸入所述直管段、索道管，斜拉索与所述滚轮本体滚动接触。与现有技术相比，本发明装置可防止斜拉索的保护层被索道管口刮破，同时能保证斜拉索较快的穿过索道管，在使用时对于吊车吊点的精度要求不高，易于操作。
