Problems solved by technology
Traditionally used for lifting steel bars is the flat lifting tongs, which are all welded parts. The selection of welding materials is limited, the welding is difficult, and the weight is heavy, which brings great difficulties to operation and design. The lifting tongs of this structure It does not have the function of turning over and cannot adapt to the complex and changeable lifting environment

Embodiment Construction
[0015] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0016] Such as figure 1 , figure 2 As shown, a position-limiting flip pliers structure includes a pliers tongue 1, which is bent to form a "U" shape and a "U"-shaped opening 101, and a waist-shaped hole 2 is opened on the pliers tongue 1. The movable plate 3 is symmetrically arranged on both sides of the pliers tongue 1, and is hinged with the pliers tongue 1 through the rotating pin 4, and extends outward on the movable plate 3 to form a boss 5; The fixed block 6 is located inside the fixed block 6 and is provided with a boss mounting hole 601 for inserting the above-mentioned boss 5 . The boss 5 is circular, and the mounting hole 601 of the boss is also a circular hole. The fixing block 6 is rectangular, and a fixing pin installation hole 7 for locking and fixing is opened in the fixing block 6 .

The invention relates to a limiting type overturn pincers structure, comprising a pincer tongue, wherein movable plates are symmetrically arranged on two sides of the pincer tongue and hinged with the pincer tongue through rotating pins; bosses are outwards extended and formed on the movable plates; fixing blocks are arranged on two sides of the pincer tongue, and are internally provided with boss mounting holes into which the bosses can be inserted. The structure is simple, the connection is reliable, and the setting is convenient; the movable plates are symmetrically arranged at two ends of the pincer tongue and hinged with the pincer tongue through the rotating pins so that the movable plates can effectively rotate relative to the pincer tongue, the flexibility is high, and the complex and various hoisting environment can be satisfied; by arranging the fixing blocks on two sides of the pincer tongue, the bosses on the movable plates can be matched with the boss mounting holes in the fixing blocks by moving the movable blocks when a steel bar is hoisted, and two sides of the steel bar can be limited in hoisting, so that the hoisting efficiency is greatly improved.
Description
technical field [0001] The invention relates to lifting equipment, in particular to a position-limiting flip tong structure. Background technique [0002] At present, steel bars need to be hoisted and transported by hoisting equipment due to their long length and heavy weight after production. Traditionally used for lifting steel bars is the flat lifting tongs, which are all welded parts. The selection of welding materials is limited, the welding is difficult, and the weight is heavy, which brings great difficulties to operation and design. The lifting tongs of this structure It does not have the flip function and cannot adapt to the complex and changeable lifting environment. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has made researches and improvements, and provides a limit-type flip clamp structure, which has the advantages of simple structural design, reliable connection, and light weight. The technical scheme ...
