Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1 - 4 , this single-arm column rotary lifting device provides two technical solutions

[0026] The first implementation method: It includes a base 1, a support column 2, a moving track 5 and an electric hoist 6. The moving track 5 is installed on the support 2 and can rotate. The electric hoist 6 is installed on the moving track and can move left and right. A stability mechanism for tensioning and stabilizing the lifted goods is provided on the support column 2. The stability mechanism includes:

[0027] The tensioning assembly 4 is provided with two groups, and both groups are arranged on the adjustment assembly 3. The distance between the two tensioning assemblies 4 is adjusted by the adjustment assembly 3. The tensioning assembly 4 includes a U-shaped member 41 and two front and rear baffles 46. A support arm 42 is fixedly connected inside the U-shaped member 41. A winding roller 47 is rotatably connected between the two baffles 46, and a pulling rope 48 is wound around the surface of the winding roller 47. A input motor 49 is fixedly connected to the front surface of the front baffle 46, and the output end of the input motor 49 is fixedly connected to one end of the winding roller 47. A first pulley 43 is rotatably connected to the end of the support arm 42. Two second pulleys 44 are rotatably arranged on the top of the support arm 42, and a third pulley 45 is rotatably arranged between the two second pulleys 44. The pulling rope 48 bypasses above the right second pulley 44, below the third pulley 45, above the left second pulley 44 and above the first pulley 43 in sequence, and one end of the pulling rope 48 bypassing the first pulley 43 is fixedly connected with a hook 410.

[0028] When the electric hoist lifts the goods, the two tensioning assemblies 4 are used to tighten and stabilize both sides of the goods, so as to ensure the stability of the goods during the lifting and moving process of the goods, and thus play a role in protecting the components in the device, improving the practicability of the device during use.

[0029] The second implementation manner is mainly different from the first implementation manner in that: the adjustment assembly 3 is used to deal with goods of different widths. The adjustment assembly 3 includes a fixed disk 31, and the fixed disk 31 is fixedly connected to the surface of the support column 2. Circular grooves 32 are opened at the top and bottom of the fixed disk 31. An arc-shaped slider 33 is slidably connected between the two circular grooves 32, and the arc-shaped slider 33 is sleeved outside the fixed disk 31. A locking bolt 34 is threadedly connected to the left side of the arc-shaped slider 33, and the locking bolt 34 penetrates through the arc-shaped slider 33 and extends into the interior of the arc-shaped slider 33. The U-shaped member 41 and the two baffles 46 are both fixedly connected to the top of the arc-shaped slider 33.

[0030] The distance between the two tensioning assemblies 4 can be adjusted, so as to tighten and stabilize goods of different widths, improving the convenience of the device during use.

[0031] During use, the goods are hung on the electric hoist 6, and at the same time the two hooks 410 are hung on the goods. The input motor 49 is started. The input motor 49 rotates and drives the winding roller 47 to rotate. The rotation of the winding roller 47 causes the pulling rope 48 to move, so as to tighten the goods. When the moving track 5 lifts and moves the goods, the input motor 49 is started and the pulling rope 48 is released, so as to keep the goods tightened during the movement of the goods. In addition, when dealing with goods of different widths, the locking bolt 34 is loosened, and the arc-shaped slider 33 is moved to adjust the distance between the two tensioning assemblies 4. After the adjustment is completed, the locking bolt 34 is tightened.
