The invention provides a radial clamping back-up roll lifting appliance. The radial clamping back-up roll lifting appliance comprises a main beam and a lifting frame. Lifting shafts are oppositely arranged on the inner sides of the lower portions of two wings of the lifting frame. The lifting shafts are inserted into corresponding holes of radial clamping rolls and are inserted and locked. The lifting frame is connected with the main beam through a rotating shaft, and therefore the radial clamping rolls deviating from the gravity center of the main beam can conduct lifting work along with swinging of the lifting frame. The lifting frame is mainly composed of a lifting beam with lifting lugs, clamping legs distributed oppositely and a transmission mechanism. The lifting lugs on the lifting beam are provided with through holes used for being connected with the main beam. The lifting beam is provided with the transmission mechanism for driving the lifting shafts on the clamping legs to clamp the to-be-lifted radial clamping rolls. The lifting beam is of a hollow structure, a sliding rail for supporting the clamping legs to linearly move horizontally is arranged in a cavity, and sealing plates are arranged at the two ends of the lifting beam to serve as limiting parts for blocking the clamping legs. According to the radial clamping back-up roll lifting appliance, the lifting frame is adopted to swing around the main beam through the rotating shaft, when the centers of the clamped radial clamping rolls deviate from the main beam, the radial clamping rolls are kept parallel to the main beam, and lifting work is stably conducted. The radial clamping back-up roll lifting appliance is suitable for being used as a back-up roll lifting appliance.
本发明提出的是一种径向夹持支撑辊吊具。包括主梁和吊架,在吊架的两翼下部内侧相向设置有吊轴,吊轴插入径向夹持辊对应的孔内并插入锁紧,吊架通过转轴与主梁连接,使得与主梁重心偏离的径向夹持辊随吊架的摆动能够进行吊装作业。所述吊架主要由带有吊耳的吊梁、相向分布的夹腿和传动机构组成,吊梁上的吊耳设有通孔用于联接主梁,在吊梁上设置有传动机构驱动夹腿上的吊轴夹紧待吊运的径向夹持辊;吊梁为中空结构,腔内设置有支撑夹腿直线平移的滑轨,吊梁两端安装封板作为阻挡夹腿的限位。本发明采用吊架通过转轴围绕主梁摆动,在夹紧后的径向夹持辊中心偏离主梁时,保持径向夹持辊与主梁平行,平稳进行吊装作业。适宜作为支撑辊吊具应用。
