[0021] As shown, Figure 3 As shown, the cable and wind rope connected tripod device further comprises a hinged joint 18, the hinged joint 18 comprises a second pin shaft 6, a first connecting fork 7, a second connecting fork 8, a tripod connecting piece 15, a first connecting fork connecting piece 16 and a second connecting fork connecting piece 17, the hinged joint 18 is installed on the end points of the other right angle and the oblique side of the triangular frame 5, one end of the upper and lower two tripod connecting pieces 15 is fixed on the end points of the other right angle and the oblique side of the triangular frame 5, one end of the upper and lower two first connecting fork connecting pieces 16 is fixed on the first connecting fork 7, and one end of the upper and lower two second connecting fork connecting pieces 17 is fixed on the second connecting fork 8, the two tripod connecting pieces 15, the two first connecting fork connecting pieces 16 and the second connecting fork connecting pieces 17 are parallel to each other, and the two first connecting fork connecting pieces 16 and the second connecting fork connecting pieces 17 are arranged between the two tripod connecting pieces 15. The second pin shaft 6 passes through the above-mentioned two tripod connecting pieces 15, the first connecting fork connecting piece 16 and the second connecting fork connecting piece 17 at the same time, so that the first connecting fork 7 and the second connecting fork 8 rotate around the second pin shaft 6, the second connecting fork 8 is provided with an ear hole, one end of the fixed steel wire rope 13 is fixed on the above-mentioned ear hole, and the other end is fixed on the other end of the crane boom 14; the first connecting fork 7 is provided with two ear holes, one end of the winch steel wire rope 11 and the catenary steel wire rope 12 are fixed on the above-mentioned two ear holes respectively, and the other ends are fixed on the winch 19 and one end of the crane boom 14 respectively.

[0022] The working principle is as follows:

[0023] After the installation according to the above relationship, the winch steel wire rope 11 and the catenary steel wire rope 12 are approximately parallel, the two acting forces of the winch steel wire rope 11 and the catenary steel wire rope 12 and the axis of the second pin shaft 6 are in the same plane, that is, the direction of the two acting forces always passes through the axis of the second pin shaft 6. Due to the structural characteristics of the second connecting fork 8, the counterforce generated by the fixed steel wire rope 13 also passes through the axis of the second pin shaft 6. Although the action lines of the winch steel wire rope 11 and the catenary steel wire rope 12 rotate around the second pin shaft 6 and the ear hole of the first connecting fork 7 as the lifting height of the crane changes, the above conditions always remain unchanged. The direction of the resultant force formed by the two acting forces of the winch steel wire rope 11 and the catenary steel wire rope 12 and the counterforce generated by the fixed steel wire rope 13 always lies in the plane of the tripod 5. The tripod 5 can effectively improve its strength as a pressure-bearing rod structure. Meanwhile, the arrangement of the pin shafts of the tripod 5 reduces the requirements for the installation position precision of the first root piece 1, the second root piece 2 and the third root piece 3 and the length precision of the fixed steel wire rope 13.

[0024] When the height, angle and force of the cable wind change, the stress of the fixed steel wire rope 13 will also change. The fixed steel wire rope 13, as an elastic element, cooperates with the damper 9 to form a shock avoidance effect, thereby reducing the impact load borne by the tripod and reducing the vibration of the tripod.

[0025] The above-described embodiments are merely used to describe the preferred implementation methods of the present application and do not limit the scope of the present application. Without departing from the design spirit of the present application, those skilled in the art can make various modifications and improvements to the technical solutions of the present application, which should all fall within the protection scope defined by the claims of the present application.
