DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1-6 As shown, the crane barrel lifting device of the utility model comprises: a crane barrel 1, a hook 2, a lifting tool 3 and a rigging 4; the crane barrel 1 is provided with a flange 11 at one end of the axial direction, and the flange 11 and the crane barrel 1 are coaxially arranged; the hook 2 is arranged on the other end of the crane barrel 1 away from the flange 11; the lifting tool 3 is symmetrically arranged, and the two lifting tools 3 are symmetrically arranged along the diameter of the flange 11, and the hook 2 and the two lifting tools 3 are located The three vertices of the triangle, and the hook 2 is located on the symmetric plane of the two lifting tools 3; the lifting tool 3 includes a main board 31, a lifting eye plate 32 and a positioning pin 33, the positioning pin 33 is welded on one end surface of the main board 31, the lifting eye plate 32 is welded on the other end surface of the main board 31, the positioning pin 33 is inserted into the through hole on the flange 11 for positioning, the main board 31 is fixedly connected to the flange 11, the hook 2 and the lifting eye plate 32 are connected with a rigging 4, and the rigging 4 is used for lifting.

[0027] In the above structure, a plurality of circular through holes 111 are provided on the circumferential surface of the flange 11, and the plurality of circular through holes 111 are arranged in a circular array with the center of the flange 11 as the center of the circle, and the positioning pin 33 is inserted into the circular through hole 111 for positioning. The diameter of the circular through hole 111 is slightly larger than the diameter of the positioning pin 33, so that the positioning pin 33 is easy to insert into the circular through hole 111.

[0028] In the above structure, the main board 31 is provided with a mounting hole 1 311 and a mounting hole 2 312, and the mounting hole 1 311 and the mounting hole 2 312 are located on both sides of the positioning pin 33. The positioning pin 33, the mounting hole 1 311 and the mounting hole 2 312 are located on the same arc line, and the diameters of the centers of the positioning pin 33, the mounting hole 1 311 and the mounting hole 2 312 are the same as the diameters of the circular through holes 1 111, so that after the positioning pin 33 is inserted into one of the circular through holes 1 111, the mounting hole 1 311 and the mounting hole 2 312 can overlap with the circular through holes 1 111 on both sides of the positioning pin 33.

[0033] In addition, a 35° groove is processed on one end of the locating pin 33 close to the main board 31, and a 10*15° chamfer is processed on the other end of the locating pin 33 away from the main board 31. The groove is to ensure the subsequent welding quality with the main board 31, and the chamfer is to facilitate the insertion of the locating pin 33 into the circular through hole 111.

[0034] When in use, the two lifting tools 3 are respectively inserted into the two circular through holes 111 of the same diameter of the flange 11, that is, the positioning pin 33 is first inserted into the circular through hole 111 for positioning, and then the main board 31 is locked to the flange 11 by the bolt 5 and the nut 6. When installing the two lifting tools 3, ensure that the upper end of the lifting eye plate 32 of the lifting tool 3 is inclined to the middle symmetrical plane of the two lifting tools 3, and then connect the rigging 4 to the lifting eye plate 32 and the hook 2 for lifting.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
