[0019] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0020] An auxiliary device for adjusting the lifting direction, see Figures 1 to 3 , including a horizontal beam 1, two groups of adjustment slots 10 are opened through the lifting end of the horizontal beam 1, and the inner side of the adjusting slot 10 is horizontally rotatably connected to the vertical beam 11, the size of the adjusting slot 10 matches the size of the vertical beam 11, and the size of the horizontal beam 1 matches the size of the vertical beam 11. A hook 18 is provided on the bottom side of the vertical beam 11; a first adjusting mechanism: used to adjust the lifting angle of the two groups of vertical beams 11, the first adjusting mechanism includes two groups of electro-hydraulic push rods 13, a connecting rod 12 is vertically passed through and fixedly installed in the middle of the vertical beam 11, the connecting rod 12 in the middle of the vertical beam 11 is rotatably connected to the inner wall of the top and bottom ends of the adjusting slot 10 through bearings, the telescopic ends of the two groups of electro-hydraulic push rods 13 are respectively hinged to the front sides of the two groups of vertical beams 11, and the end of the electro-hydraulic push rod 13 away from the vertical beam 11 is hinged to the front side of the horizontal beam 1.

[0021] The two groups of electro-hydraulic push rods are controlled to work synchronously through the corresponding controller. Since the connecting rod 12 in the middle of the vertical beam 11 is rotatably connected to the adjustment slot 10, the two ends of the electro-hydraulic push rod 13 are respectively hinged to the vertical beam 11 and the horizontal beam 1. During the extension and retraction process of the electro-hydraulic push rod 13, it can drive the vertical beam 11 to rotate, thereby adjusting the placement angle of the material hoisted on the bottom side of the vertical beam 11, further solving the problem of the existing hoisting device that when the material is hoisted to the target position, it is difficult to adjust the direction of the material and the wire rope 17, and it is inconvenient to adjust the material placement angle.

[0022] For details, see Figures 1 to 3, The second adjusting mechanism: used to adjust the hoisting position of the hook 18, the second adjusting mechanism includes a servo motor 22, limit slots 14 are symmetrically provided at the front and rear ends of the vertical beam 11, the inner side of the limit slot 14 is slidingly connected to the limit block 15, and the outer side of the vertical beam 11 is slidingly connected with two groups of fixed frames 16, the limit block 15 is placed on the outer side of the limit slot 14 and is fixedly connected to the inner wall of the fixed frame 16, the bottom side of the fixed frame 16 is fixedly connected with a wire rope 17, the hook 18 is fixedly connected to the end of the wire rope 17 away from the fixed frame 16, a connecting groove 2 is horizontally penetrated through the middle part of the limit block 15, the inner side of the connecting groove 2 is threadedly connected with a screw rod 21, the shaft end of the servo motor 22 is fixedly connected to one end of the screw rod 21, and the servo motor 22 is fixedly connected to one end of the vertical beam 11.

[0023] The servo motor 22 is controlled by the corresponding controller to drive the screw rod 21 to rotate. Since the screw rod 21 is threadedly connected to the connecting groove 2 in the middle of the limit block 15, the screw rod 21 can drive the limit block 15 to move back and forth in the limit groove 14 during rotation, thereby driving the fixed frame 16 to slide on the outside of the vertical beam 11, and the hook connected to the wire rope 17 on the bottom side of the fixed frame 16 can be adjusted to its use position, and further materials of different sizes can be hoisted.

[0024] For further information, see Figures 1 to 3 The threads on the front and rear sides of the screw rod 21 rotate in opposite directions, and the screw rod 21 is rotatably connected to the vertical beam 11 through a bearing.

[0025] Because the threads on both sides of the screw rod 21 rotate in opposite directions, the servo motor 22 drives the screw rod 21 to rotate, and can simultaneously drive the two sets of limit blocks 15 to move relative to or in opposite directions in the limit groove 14, thereby quickly adjusting the distance between the two sets of fixed frames 16, and further quickly adjusting the lifting positions of the two sets of hooks 18.
