Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
See accompanying drawing.
In an embodiment of the present utility model, a kind of trailing arm, comprises base 1 and cantilever 2, this base 1 is by the machine-shaping of strip-shaped steel plate one, in 7 fonts, comprise installation portion 11 and support portion 12, and the angle α between installation portion 11 and support portion 12 is the acute angle between 70 ° ~ 80 °; Especially, this sharp angle α size is 75 °, makes support portion length reasonable, has best load-carrying properties.Installation portion 11 is provided with two installing holes 16; Cantilever 2 in the present embodiment is C-type steel, this cantilever 2 along the end of support portion 12 to the vertical line vertical welding of installation portion 11 on installation portion 11, and the end of support portion 12 is just in time welded on the bottom surface of this cantilever 2, two place's pads are respectively the first pad 12 and the second pad 14.
Trailing arm in the present embodiment, the bottom surface of its cantilever 2 is evenly provided with some connecting holes 17 along its axis; Especially, two ends of above-mentioned connecting hole are circular arc, are one group of straight line be parallel to each other between the two ends.
Adopt said structure, the support arm structure in the present embodiment is simple, lightweight and load-carrying properties are strong; And the connecting hole 17 on cantilever 2 make to be carried on crane span structure on cantilever 2 can free adjustment installation site, easy to use.
As further improvement of the utility model, as shown in Figure 4, in another embodiment of the present utility model, between the bottom surface of cantilever 2 and support portion 12, support member 3 is also provided with; This support member 3 is also by the machine-shaping of strip-shaped steel plate one, in 7 fonts, comprise the long limit and minor face with an angle β, two free ends of long limit and minor face are all welded on support portion 12, and the top of this support member 2 corner is welded on the bottom surface of cantilever 2, form the 3rd pad 15.
Especially, as further improvement of this embodiment, above-mentioned 3rd pad 15 midpoint of line between first pad 13 and the second pad 14 on cantilever 2 bottom surface.
Especially, the angle of the angle β between the above-mentioned long limit of support member 3 and minor face is 90 °.
