Abstract
The utility model discloses hanging tongs used for clamping a large angle steel of an electric power iron tower. The hanging tongs comprise a first clamping arm and a second clamping arm which are hinged with each other, wherein one end parts of the first clamping arm and the second clamping arm are respectively a first hoisting arm and a second hoisting arm, hoisting holes are formed in the first hoisting arm and the second hoisting arm, the first clamping arm and the first hoisting arm as well as the second clamping arm and the second hoisting arm are of a linear whole structure, and the other end parts of the first clamping arm and the second clamping arm are respectively tong claws which are corresponding to each other. According to the hanging tongs, the design is reasonable, the clamping arms and the hoisting arms are of linear whole structures, stress distribution is uniform, torsion resistance performance is strong and the torsion resistance strength is high. The included angle formed by the clamping arms and the tong claw is 60 degrees, and when the angle steel is hoisted, the stress is stable, so that the accident of angle steel slipping can be avoided.
Description
Technical field
The utility model relates to a kind of lifting device, is specifically related to the tongs of the big angle steel of a kind of clamping electric power tower.
Background technology
Angle steel is commonly called as angle bar, is the rectangular steel of the orthogonal one-tenth dihedral in both sides that it has the branch of equal angle and L-bar.Angle steel can be formed various primary structure member by the different needs of structure, also can be used as the attaching parts between the member, it is widely used for various building structure and engineering structure, as house beam, bridge, electric transmission pole tower, handling machinery, boats and ships, industrial furnace, reaction tower, receptacle stand and warehouse shelf etc.When the manufacturing electric power tower lifts transportation to angle steel, need to use tongs usually.Tongs is owing to have intensity height, safe lifting is reliable, handling is convenient, flexible advantage, thereby it is used widely, and particularly in the production process of electric power tower, needs a kind of tongs reasonable in design, to improve the lifting conveying efficiency, to guarantee production safety.
The utility model content
Technical problem to be solved in the utility model provide a kind of stressed evenly, can guarantee the tongs of the big angle steel of clamping electric power tower of safe lifting.
For solving the problems of the technologies described above, the tongs of the big angle steel of the utility model clamping electric power tower, comprise first clamping limb and second clamping limb that are hinged, one end of described first clamping limb and second clamping limb is respectively the first lifting arm and the second lifting arm, the described first lifting arm and the second lifting arm are provided with hole for hoist, described first clamping limb and the first lifting arm, described second clamping limb and the second lifting arm are linear integral structure, and the other end of described first clamping limb and second clamping limb is respectively mutual cooresponding chela.
For further improving stress equalization of the present utility model, preventing that the angle steel landing from causing the generation of safety misadventure, the angle that the medial surface of above-mentioned first clamping limb and the medial surface of chela form is 60 degree.
Further, the angle of the medial surface of the medial surface of above-mentioned second clamping limb and chela formation is 60 degree.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is reasonable in design, and clamping limb and lifting arm are linear integral structure, stressed being evenly distributed, and torsional property is strong, the intensity height.The angle that clamping limb and chela form is 60 degree, and stability under loading during the angle steel lifting can prevent the generation of angle steel landing accident.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the tongs of the big angle steel of the utility model clamping electric power tower.
The specific embodiment
As shown in Figure 1, the tongs of the big angle steel of clamping electric power tower, comprise first clamping limb 4 and second clamping limb 5 that are hinged, one end of described first clamping limb 4 and second clamping limb 5 is respectively the first lifting arm 3 and the second lifting arm 2, the described first lifting arm 3 and the second lifting arm 2 are provided with hole for hoist 1, described first clamping limb 4 and the first lifting arm 3, described second clamping limb 5 and the second lifting arm 2 are linear integral structure, and the other end of described first clamping limb 4 and second clamping limb 5 is respectively mutual cooresponding chela 6.The angle that the medial surface of the medial surface of described first clamping limb 4 and chela 6 forms is 60 degree.The angle that the medial surface of the medial surface of described second clamping limb 5 and chela 6 forms is 60 degree.
When lifting transport operation, the dual-side for the treatment of handling angle steel 7 is placed respectively on the chela 6 of first clamping limb 4 and second clamping limb 5, chela 6 is lived angle steel 7 secure, because first clamping limb 4 and second clamping limb 5 are 60 degree with the angle that chela 6 forms, guarantee stability under loading, can prevent the generation of angle steel landing accident.
