The invention relates to a fastening device and method for lifting legs of a lifting appliance, and belongs to the technical field of manufacturing of large power transformers. According to the technical scheme, a rotating shaft (8) is wound with a tight wrapping belt (6), the end of the tight wrapping belt is provided with a hanging ring (9), and the tight wrapping belt is arranged on a plurality of lifting legs (10) of the lifting appliance in a surrounding mode in the circumferential direction and connected with a tail hook (5) through the hanging ring; limiting cushion blocks (11) are arranged on the lifting legs, limiting grooves (12) are formed in the limiting cushion blocks, and the tight wrapping belts (6) are arranged in the limiting grooves. One end of the rotating shaft (8) is provided with a ratchet wheel (2), and the other end is provided with a handle (4); the ratchet wheel is matched with a check pawl (13), and the check pawl is connected with a rotating rod (14). According to the device, the tight wrapping belts on the circumference are located at the same height, fastening and binding operation is easy and convenient, the lifting appliance lifting leg can be rapidly and normatively bound only by one person, the tight wrapping belts are stored after use is completed, manpower and material resources are saved, and the device is suitable for the large power transformer manufacturing industry.

    本发明涉及一种吊具吊腿拴紧装置及方法,属于大型电力变压器制造技术领域。技术方案是:转轴(8)上缠绕设置紧包带(6),紧包带端部设有挂环(9),紧包带沿圆周方向围绕设置在吊具的多个吊腿(10)上,并通过挂环与机尾挂钩(5)连接;吊腿上设有限位垫块(11),限位垫块上设有限位槽(12),紧包带(6)设置在限位槽内;转轴(8)一端设有棘轮(2),另一端设有手柄(4);棘轮与止回棘爪(13)相匹配,止回棘爪与转动杆(14)连接。本发明使圆周上紧包带处于同一高度,拴紧绑扎操作简便,仅用一人就能快速且规范地对吊具吊腿进行绑扎,并在使用完成后将紧包带进行收纳,节省人力物力,适合于大型电力变压器制造行业。
