[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0022] refer to Figure 1-Figure 4The utility model discloses an adjustable hook device, comprising a balance beam 1 which is hollow inside and open at both ends, wherein a guide rail 6 is arranged at the inner top of the balance beam 1 along its length direction, and the guide rail 6 is a symmetrically arranged L-shaped plate. A guide hole 7 is arranged at the bottom of the balance beam 1 along its length direction, and the guide hole is arranged corresponding to the guide rail, a hook 2 is arranged inside the balance beam 1, and one end of the hook 2 passes through the guide hole 7 and extends into the guide rail 6 and is slidably connected with the guide rail 6, and an adjustment mechanism 3 for adjusting the position of the hook 2 is arranged at both ends of the balance beam 1.
[0023] Furthermore, a bearing 21 is fixed to the top of the hook 2 through a column sleeve, that is, the column is fixed in the inner ring of the bearing, and the bearing 21 is located in the guide rail 6. When the hook is in the guide rail, the bearing can not only realize the rotation of the hook, but also realize the movement of the hook along the guide rail.
[0024] Furthermore, the hook 2 is U-shaped, and a semicircular arc groove or a V-shaped groove is provided at the hook head, so that the hoisted object is firmly fixed on the hook, ensuring the safety of the hoisting process.
[0025] Furthermore, the hooks 2 are provided with two, and the adjustment mechanisms 3 provided at both ends of the balance beam 1 are detachably connected to the corresponding hooks 2. The side wall of the hook 2 located inside the balance beam 1 is provided with a blind hole 22 corresponding to the open end of the balance beam 1, and the blind hole 22 is provided with an internal thread. The adjustment mechanism is detachably connected to the blind hole on the hook.
[0026] Specifically: the adjustment mechanism 3 includes an end plate 5 fixed to the end face of the balance beam 1, the end plate closes the open end of the balance beam, a screw 32 is penetrated through the end plate 5, the screw is movable relative to the end plate, the screw 32 is adapted to the blind hole 22, that is, one end of the screw is inserted into the blind hole and threadedly connected, and a nut 31 is provided at the end of the screw 32 extending outside the end plate 5, which can fix the screw to the end plate.
[0027] When adjusting the distance between the two hooks, extend the screw into one end of the balance beam and connect it to the blind hole, then operate the screw. With the assistance of the guide rail and the bearing, the hooks move toward or away from each other, thereby reducing or extending the distance between the two hooks. After the position adjustment is completed, fix the screw to the end plate with a nut.
[0028] When the hook needs to achieve 360° rotation, screw the nut to loosen the fixation on the screw, and then screw the screw to disengage it from the blind hole, that is, the screw is disengaged from the hook, and then rotate the hook to rotate it to the specified position, that is, the hook parts of the two hooks correspond, and then fix the screw to the blind hole, that is, fix the hook, and fix the screw with the nut.
[0029] Furthermore, at least one lifting ring 4 is provided on the top of the balance beam 1. When multiple lifting rings are provided, the lifting rings are symmetrically distributed.
[0030] When using the utility model, the adjustable hook device is suspended on the lifting machinery by passing through the two rings 4 on the balance beam 1 with a steel wire rope or a sling. The distance between the two parallel hooks 2 is reduced or extended by tightening or loosening the adjustment mechanism 3 at both ends of the balance beam 1 to meet the needs of lifting objects of different lengths. The U-shaped design of the hook 2 makes the lifting process safer, and there is no possibility of the suspended object falling during the lifting process. In addition, when the adjustment mechanisms 3 at both ends are completely loosened, the hook 2 can achieve 360° rotation. When the two hooks 2 are rotated to relative positions, another type of lifting can be adapted. The design of the semicircular arc structure or V-shaped structure on the hook 2 also allows the suspended object to be firmly fixed on the hook, ensuring the safety of the lifting process.
