The invention discloses a lifting appliance, relates to the technical field of roller transfer, and solves the technical problems of inconvenience and low efficiency when a roller is lifted through a lifting belt. The lifting appliance comprises an outer beam, an inner beam, two opening and closing devices arranged at the two ends of the length of the inner beam respectively and two time sequence mechanisms arranged at the two ends of the length of the inner beam respectively, the inner beam is vertically and movably arranged in the outer beam, a lifting hole is formed in the top of the inner beam, pin shafts are arranged at the two ends of the length of the inner beam respectively, and each opening and closing device comprises a pressing plate, a hand joint and a mechanical hand which are sequentially connected. The pin shaft penetrates through the pressing plate, the mechanical arm is rotatably connected with the outer beam, and the hand joint is used for closing the mechanical arm when the inner beam moves upwards relative to the outer beam and opening the mechanical arm when the inner beam moves downwards relative to the outer beam. And when the time sequence mechanism is pushed once by the lifted lifting target, the time sequence mechanism changes once from two states of unlocking the pin shaft and recovering the locking of the pin shaft. And through automatic clamping and automatic loosening, the operation step of picking and hanging the lifting belt is omitted, the self-locking function is achieved, and the lifting efficiency is improved.
本发明公开一种吊具,涉及轧辊转运技术领域,解决了轧辊通过吊带吊运存在的不便、效率低的技术问题。吊具包括外梁、内梁、分别设置于内梁长度两端的两个开闭器和分别设置于内梁长度两端的两个时序机构,内梁可竖向移动地设置外梁内,内梁的顶部开设有吊孔,内梁的长度两端分别设置销轴,开闭器包括依次连接的压板、手关节和机械手,销轴穿设于压板,机械手与外梁可转动连接,手关节用于在内梁相较于外梁上移时关闭机械手、在内梁相较于外梁下移时打开机械手,时序机构在被上升的吊取目标推动一次则从解除对销轴的锁定、恢复对销轴的锁定的两种状态中变化一次。通过自动夹取、自动松开,免去摘挂吊带的操作步骤并具备自锁功能,增加吊运效率。
