Fire-resistant and flame-retardant structure for suspension bridge cable clamp
The invention discloses a fire-resistant flame-retardant structure for a suspension bridge cable clamp, which comprises a main cable and a cable clamp fixed on the main cable, and gaps between two ends of the cable clamp and the main cable are filled with fireproof sealant; the fireproof sealing ring sleeves the main cable and is attached to a gap between the cable clamp end and the main cable; the rotating seat is connected to the locking screw rod close to the end head of the cable clamp; one end of the elastic pull rod is hinged to the rotating part of the rotating seat and faces the outer side of the end of the cable clamp; the annular fireproof cover is arranged on the outer side of the cable chuck end in a sleeving mode and connected with the end, away from the rotating base, of the elastic pull rod, and the annular fireproof cover is pressed on the fireproof sealing ring through elastic pulling force of the elastic pull rod. According to the fireproof structure, the annular fireproof cover can perform adaptive deformation movement along with movement of the cable clamp, fireproof sealing of a gap between the cable clamp and the main cable is always kept, and gap fireproof failure caused by long-time displacement of the cable clamp can be overcome.
本发明公开了一种用于悬索桥索夹的抗火阻燃结构，包括主缆，和固定在主缆上的索夹，索夹两端与主缆之间的缝隙填充有防火密封胶；防火密封圈套设在主缆上，且与索夹端头与主缆之间的缝隙贴合；转动座连接在靠近索夹端头的锁紧螺杆上；弹性拉杆一端与转动座的转动部铰接，且朝向索夹端头的外侧；环形防火罩套设在索夹头端外侧，且与弹性拉杆远离转动座的一端连接，并通过弹性拉杆的弹性拉力将环形防火罩压紧在防火密封圈上。本发明采用的防火结构能够使得环形防火罩能够随着索夹的运动而进行适应性变形运动，始终保持对索夹与主缆之间缝隙的防火密封，能够克服长时间索夹位移造成的缝隙防火失效。
