The invention discloses a roll collar disassembling and assembling clamp and a crown block. The roll collar disassembling and assembling clamp comprises a first clamping component, a second clamping component and a transmission assembly; the second clamping component is arranged opposite to the first clamping component, and the first clamping component and the second clamping component are used for clamping the roll collar; and the transmission assembly is in transmission connection with the first clamping component and the second clamping component so as to drive the first clamping componentand the second clamping component to get close to each other or get away from each other, the transmission assembly is provided with a hoisting component, and the hoisting component is used for beinghooked to a lifting hook of the crown block. According to the roller collar disassembling and assembling clamp, the first clamping component and the second clamping component can clamp the roller collar under transmission of the transmission assembly, the clamping strength is good, and the roller collar disassembling and assembling clamp can be matched with the lifting hook of the crown block in ahooked mode through the lifting component and can be matched with the crown block so that the roller collar can be stably clamped and disassembled. The clamp has the advantages of being capable of clamping conveniently and stably and small in labor investment, and the working efficiency of disassembling the roll collar is improved.

    本发明公开一种辊环拆装夹具和天车,辊环拆装夹具包括:第一夹持构件;第二夹持构件,第二夹持构件与第一夹持构件相对设置,第一夹持构件与第二夹持构件用于夹持辊环;传动组件,传动组件传动连接第一夹持构件和第二夹持构件,以驱动第一夹持构件与第二夹持构件相互靠近或远离,传动组件设有起吊构件,起吊构件用于钩设于天车的吊钩。本发明提出的辊环拆装夹具,其第一夹持构件和第二夹持构件在传动组件的传动下能够夹持辊环,具有较好的夹持强度,并通过起吊构件能与天车的吊钩钩设配合,能够与天车配合以将辊环较为稳定的夹持并拆卸,具有夹持方便、夹取稳定以及劳动力投入小的优点,提升了拆卸辊环的工作效率。
