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

[0018] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0019] like Figure 1 to Figure 3 As shown in the figure, a cooperative main flipping pliers structure includes a pliers tongue 1, which is located on both sides of the pliers tongue 1 and is hinged with a movable plate 2 through a rotating pin 3 respectively. One end of the pliers tongue 1 bends and extends along the other end to form a "U". Shaped opening 104, one end of movable plate 2 has hoisting hole 201, and the other end has rotation pin installation hole 202. One end of the pliers tongue 1 is extended to form a first lock tongue 101, the other end of the pliers tongue 1 is extended to form a second lock tongue 102, and the curved part of the pliers tongue 1 also extends outward to form a boss 105, and the boss 105 opens inwardly. There are through holes 103 . The length of the clamp tongue 1 with the first lock tongue 101 is gre...

Abstract

The invention relates to a cooperative type main turning pincer structure which comprises a pincer tongue, wherein moving plates are respectively hinged to the two sides of the pincer tongue; one end of the pincer tongue is bent and extended to form a U-shaped opening; one end of the pincer tongue is extended to form a first locking tongue; the other end of the pincer tongue is extended to form a second locking tongue; the bent part of the pincer tongue is further extended outwards so as to form bosses; through holes are formed inside the bosses. The cooperative type main turning pincer structure is simple in structure and convenient to assemble; as the moving plates are symmetrically arranged at the two ends of the pincer tongue and are hinged to the pincer tongue through turning pins, rotation of the moving plates relative to the pincer tongue is effectively achieved with high flexibility, and complex and variable hoisting environment can be met; as the bosses are formed when the bent part of the pincer tongue is extended outwards, the structure can be connected with other fittings, the hoisting requirements of steel plates of different lengths can be met, and the hoisting efficiency is greatly improved.

Description

technical field [0001] The invention relates to hoisting equipment, in particular to a turning clamp structure used for hoisting steel plates. Background technique [0002] At present, the steel plate needs to be hoisted and transported by hoisting equipment due to its 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] Aiming at the above-mentioned shortcomings in the existing production technology, the applicant provides a reasonable structure of a matching main flipping tongs structure, which has the advantages of simple structure design, reliable connecti...
