DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] like Figure 1-3As shown, an embodiment of the utility model proposes a hook structure for mounting on a pulling arm, comprising: a connecting arm 1, on which a pulley 2 is rotatably mounted; the pulley 2 is connected to a steel wire rope on a lifting device, which is a prior art.

[0019] A fixed column 3, the fixed column 3 is fixedly installed at the bottom of the connecting arm 1, a support plate 4 is fixedly installed at the bottom of the fixed column 3, and a sliding frame 5 is slidably installed on the outer peripheral side of the support plate 4;

[0020] A mounting plate 6 is fixedly mounted on the bottom of the sliding frame 5, a movable plate 7 is slidably mounted on the bottom of the mounting plate 6, a connecting plate 8 is detachably mounted on the bottom of the movable plate 7, a lifting hook 9 is rotatably mounted on the bottom end of the connecting plate 8, a driving motor 10 for driving the lifting hook 9 to rotate is mounted on the connecting plate 8; a limiting plate is rotatably mounted on the lifting hook 9, a reset spring is fixed between the limiting plate and the lifting hook 9, which can limit the position of the lifting object contacted by the lifting hook 9 to prevent it from falling off when used for lifting.

[0021] The moving assembly 11 is installed at the bottom of the support plate 4, and is used to drive the moving plate 7 to move left and right. The moving assembly 11 includes two positioning plates 111 symmetrically distributed and fixedly installed at the bottom of the mounting plate 6, and a moving screw 112 is rotatably installed between the two positioning plates 111, and a forward and reverse motor 113 is fixedly installed on one of the positioning plates 111, and the forward and reverse motor 113 is fixedly connected to one end of the moving screw 112, and the moving screw 112 is threadedly connected to the moving plate 7.

[0022] When items need to be hoisted, the connecting arm 1 is moved to the specified position through the lifting equipment, thereby driving the hoisting hook 9 to move. When the hoisting hook 9 needs to be adjusted over a short distance, the moving component 11 can be enabled, specifically, the forward and reverse motor 113 is started to drive the moving screw 112 to rotate forward and reverse, thereby driving the moving plate 7 threadedly connected to it to move left and right, and then driving the hoisting hook 9 at the bottom of the connecting plate 8 to move to the specified position. At the same time, the driving motor 10 can be enabled to drive the hoisting hook 9 to rotate, so that the hoisting hook 9 can be rotated to adjust the angle, thereby facilitating the opening position of the hoisting hook 9 to align with the items to be hoisted, facilitating the hoisting of items, avoiding the trouble and danger of manual adjustment of the hoisting by the staff, greatly reducing the labor intensity of the staff, and having certain practicality.

[0023] like Figure 3 As shown, in some embodiments, a slide groove is constructed on the mounting plate 6, and the top end of the movable plate 7 is T-shaped and is slidably mounted in the slide groove.

[0024] The movable plate 7 is T-shaped and slides in the slide groove, which is convenient for supporting the movable plate 7 and protecting the movable screw 112, thereby avoiding the problem that when the lifting hook 9 lifts the object, the movable screw 112 is subjected to all stress points, resulting in bending and affecting the use.

[0025] like Figure 2 As shown, in some embodiments, a circular groove is constructed on the connecting plate 8, a circular plate 12 is fixedly installed on the top of the lifting hook 9, the circular plate 12 is rotatably installed in the circular groove, and the output end of the driving motor 10 is fixedly connected to the circular plate 12.

[0026] The circular plate 12 is rotatably installed in the circular groove, which is convenient for stabilizing the connection of the lifting hook 9. When the lifting hook 9 is subjected to force, it will not pull the connection between the output end of the driving motor 10 and the circular plate 12 to cause damage and affect the rotation.

[0027] like Figure 2 As shown, in some embodiments, a buffer assembly 13 for buffering and absorbing the suspension hook 9 is installed between the support plate 4 and the sliding frame 5. The buffer assembly 13 includes a plurality of buffer springs 131 fixedly installed between the support plate 4 and the sliding frame 5, and a plurality of dampers 132 fixedly installed between the support plate 4 and the sliding frame 5.

[0028] During the lifting process, the position where the hook is connected to the equipment bears the entire gravity and is prone to breakage. The multiple buffer springs 131 and dampers 132 are set between the support plate 4 and the sliding frame 5. When the lifting hook 9 is hung with goods, the buffer springs 131 and dampers 132 will be squeezed by gravity to share part of the gravity. When the goods are unloaded, the rebound force of the squeezed return spring 131 cooperates with the damper 132 to produce a buffering and shock-absorbing effect, which will remove part of the buffering force, so that the lifting hook 9 is protected by buffering and its service life is increased.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
