The invention discloses a synchronous lifting mechanism for double safety tongs. The synchronous lifting mechanism comprises two supports, the two rotating shafts are rotationally connected between the two supports, and trigger rods and fixed connecting rods are fixed to the rotating shafts; the linkage rod is hinged to the two fixed linkage rods; the safety tongs comprise a tongs body fixed to the end of the support, a lifting sliding groove is formed in the tongs body, two vertical sliding grooves are formed in the tongs body, a vertical sliding rod is inserted into the vertical sliding grooves, a lifting push rod and a side push rod are hinged to the upper end of the vertical sliding rod, a lifting plate is hinged to the lifting push rod and fixed to a rotating shaft, and the side push rod is hinged to the side push rod. Clamping sliding grooves are formed in the left side and the right side of the lifting sliding groove, clamping blocks are installed in the clamping sliding grooves, extension rods are fixed to the clamping blocks, side vertical rods are fixed to one ends of the extension rods, and the upper ends of the side vertical rods are hinged to the corresponding side push rods. After the trigger rod rotates, the two rotating shafts can be driven to rotate together at the same time, so that the four safety tongs are braked at the same time, and the safety is high.
本发明公开了一种双安全钳同步提拉机构,包括:两根支架;两根转动轴,两根转动轴均转动连接在两根支架之间,转动轴上固定有触发杆和固定联杆;联动杆,联动杆与两根固定联杆铰接;安全钳,安全钳包括固定在支架端部的钳主体,钳主体上设有升降滑槽,钳主体上设有两个竖直滑槽,竖直滑槽内插接有竖直滑杆,竖直滑杆的上端铰接有提拉推杆和侧推杆,提拉推杆上铰接有提拉板,提拉板固定在转动轴上,升降滑槽的左右两侧均设有夹紧滑槽,夹紧滑槽内安装有夹紧块,夹紧块上固定有延伸杆,延伸杆的一端固定有侧竖杆,侧竖杆的上端与对应的侧推杆铰接。触发杆转动后能够同时带动两根转动轴一同转动,从而实现四个安全钳同时制动,安全性高。
