The invention belongs to the technical field of grabbing and embracing pliers, and particularly discloses a grabbing and embracing pliers for calcium carbide, which comprises a lifting frame, a lifting block, a lock hook, two L-shaped main beams and a locking mechanism, the side vertical section of the lifting frame is in a rectangular-ambulatory-plane shape, the top of the lifting frame is fixedly connected with a lifting lug, the lock hook is locked with the lifting frame through the locking mechanism, and two first long holes are formed in the lifting frame; the lifting block is connected with the lifting frame in a sliding mode, a first fixing pin penetrates through the lifting block and is connected with the first long hole in a sliding mode, a base is fixedly connected to the bottoms of the two L-shaped main beams, a fixing assembly is connected to the base, a cavity is formed in the lifting block, each L-shaped main beam is provided with a groove hole, and each L-shaped main beam is hinged to a gripper arm; and each gripper arm is movably connected with the lifting block. Through cooperation of the lifting frame and the lifting block, the lock hook can be automatically locked on the premise that the clamp claws and the lifting block are not convenient to descend, so that the process of releasing the holding clamp is coherent and smooth, the structure is ingenious, and the process of clamping calcium carbide is more efficient and convenient.
本发明属于抓抱钳技术领域,具体公开了一种电石用抓抱钳,包括提升架、提升块、锁钩、两个L形主梁和锁定机构,提升架侧立截面呈回字形且顶部固接有吊耳,锁钩通过锁定机构与提升架锁定,提升架上开设有两个第一长孔,提升块与提升架滑动连接,提升块上贯穿有第一固定销,第一固定销与第一长孔滑动连接,两个L形主梁的底部固接有底座,底座上连接有固定组件,提升块内部设有空腔,每个L形主梁均开设有槽孔,每个L形主梁均铰接有钳爪,每个钳爪与提升块活动连接。本发明通过提升架和提升块的配合,在不便于降下钳爪和提升块的前提下,也能自主锁定锁钩,使得释放抱钳的过程连贯顺畅,结构巧妙,使得夹持电石的过程更加高效便捷。
