The invention discloses a variable-distance double-hook long steel rail lifting appliance which comprises a lifting ring plate, a positioning and guiding device and a pair of rail clamping tongs, a lifting ring is fixedly arranged on the lifting ring plate, a positioning guide device is arranged on the front side of the lifting ring plate, another positioning guide device is arranged on the rear side of the lifting ring plate, the two positioning guide devices are symmetrically distributed along the lifting ring, guide grooves are formed in the positioning guide devices in a front-back penetrating mode, and limiting grooves are formed in the lower portions of the two ends of each guide groove. The guide rod is connected with a sliding block, the sliding block is arranged on the positioning guide device in a sliding mode, and a rail clamp is hinged to the lower end of the sliding block and used for clamping a steel rail. Switching between the rail bottom non-spacing state and the rail bottom fixed spacing state of the steel rail can be achieved, switching between locking and opening and closing of the rail clamping tongs is achieved in cooperation with the unlocking and locking device, operation is easy, labor is saved, the labor intensity of workers can be relieved, and the loading and unloading efficiency is improved.
本发明公开了一种可变距双钩长钢轨吊具,包括吊环板、定位导向装置和夹轨钳;吊环板上固定设有吊环,吊环板上前侧设有定位导向装置,吊环板上后侧设有另一定位导向装置,两定位导向装置沿吊环对称分布,定位导向装置前后贯穿开设有导向槽,导向槽两端下部设有限位凹槽,导向槽内滑动连接有导杆,导杆与滑动块相连,滑动块可滑动设置在定位导向装置上,滑动块下端铰接有夹轨钳,夹轨钳用于夹住钢轨。本发明可实现钢轨轨底无间距状态和轨底固定间距状态间的切换,配合解脱锁定装置实现对夹轨钳锁定和开合的切换,操作简单省力,可降低人工劳动强度,提高装卸效率。
