DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 The utility model provides a technical solution: a round steel lifting hook device, including a hanger 15 and a right clamp 1 and a left clamp 13 arranged on the hanger 15 and capable of opening and closing, the right clamp 1 is hinged with a right stretching rod 3, the middle part of the hanger 15 is fixedly connected with a right connecting rod bracket 7, the right connecting rod bracket 7 is hinged with a right connecting rod 6, the right connecting rod 6 is movably sleeved with a right rotating body 4 at one end away from the right connecting rod bracket 7, the lower end of the right rotating body 4 is threadedly connected to one end of the right stretching rod 3, the middle part of the hanger 15 is symmetrically fixedly connected to the right connecting rod bracket 7 with a left connecting rod bracket, and the left connecting rod bracket 8 and the left clamp 13 are arranged in sequence. A left connecting rod, a left rotating body 10 and a left stretching rod 11 are arranged. The left connecting rod bracket 8, the left connecting rod, the left rotating body 10 and the left stretching rod 11 have the same structure as the right connecting rod bracket 7, the right connecting rod 6, the right rotating body 4 and the right stretching rod 3, and the connection relationship between the components is the same. When the right rotating body 4 is rotated, the right stretching rod 3 moves along the axial direction of the right rotating body 4, driving the right chuck 1 to approach or move away from the center plane of the hanger 15; when the left rotating body 10 is rotated, the left stretching rod 11 moves along the axial direction of the left rotating body 10, driving the left chuck 13 to approach or move away from the center plane of the hanger 15.

[0023] The utility model is provided with a left rotating body 10 and a right rotating body 4, a left stretching rod 11 and a right stretching rod. Since the stretching rod and the rotating body are threaded together, and one end of the stretching rod is connected to the chuck for rotation and cannot drive the chuck to rotate, when the rotating body is rotated, the stretching rod moves along the thread in the inner cavity of the rotating body, thereby pulling the two semicircular left chucks 13 and the right chucks 1 together. When closing, the left chucks 13 and the right chucks 1 clamp and fix the round steel to be lifted; the stretching rod can also be extended by rotating the rotating body, thereby adjusting the opening and closing degree of the left chucks 13 and the right chucks 1, and then directly inserting one end of the round steel and being able to move along the round steel to adjust the lifting position. The entire hook device can clamp the round steel to be lifted by adjusting the opening size between the left chuck 13 and the right chuck 1, or the opening size of the left chuck 13 and the right chuck 1 is adjusted in advance and then put on the round steel. The entire hook device can clamp and lift round steels of different sizes, and is easy to adjust and use.

[0024] Reference Figure 2 and 3 As shown, in this embodiment, the upper portions of the right chuck 1 and the left chuck 13 are respectively provided with a recess and a projection, and each of the recess and the projection is provided with a through hole. The right chuck 1 and the left chuck 13 are rotatably connected to the lower portion of the hanger 15 through the through hole. By movably connecting the right connecting rod 6 and the left connecting rod 9 to the right rotating body 4 and the left rotating body 10, respectively, when the stretch rod is extended or retracted by rotating the rotating body, idling occurs between the rotating body and the left connecting rod 9 and the right connecting rod 6, thereby not affecting the normal rotation of the rotating body.

[0025] In this embodiment, the left chuck 13 and the right chuck 1 are fixedly connected to the right chuck bracket 2 and the left chuck bracket 12 respectively. The right chuck bracket 2 and the left chuck bracket 12 are rotatably connected to the right stretching rod 3 and the left stretching rod 11 respectively.

[0026] In this embodiment, the right connecting rod 6 and the right connecting rod bracket 7, the left connecting rod 9 and the left connecting rod bracket 8, the right chuck bracket 2 and the right stretching rod 3, and the left chuck bracket 12 and the left stretching rod 11 are all rotatably connected by hinge bolts 14 and nuts 16.

[0027] Reference Figure 2 and 4 As shown, in this embodiment, a through slot 17 is provided through the middle of both the right-hand rotating body 4 and the left-hand rotating body 10. One end of the right connecting rod 6 and the left connecting rod 9 extends into the through slot 17 and is threadedly connected to a limit nut 5. The through slot 17 and the limit nut 5 ensure a stable connection between the right connecting rod 6 and the left connecting rod 9 and the rotating body, while also facilitating routine disassembly and installation of the connecting rods and the connecting rod bracket.
