[0024] Example 1 provides a workpiece lifting device:

[0025] The base 10 and the guide rail 20 are both fixed to the ground. The base 10 is rotatably connected to the column 30, and a bracket 40 is provided on the column 30. A frame 50 is slidably connected to the bracket 40. A winch 51 is installed on the frame 50. The traction rope of the winch 51 is connected to a hook 52. By connecting the hook 52 to the lifting ear of the workpiece, the winch 51 is controlled to work, so that the workpiece can be pulled upward.

[0026] The bracket 40 is provided with a ball seat 41 embedded in the guide rail 20. The guide rail 20 is arc-shaped. The column rod 30 can rotate on the base 10 to drive the bracket 40 to rotate. The ball seat 41 on the bracket 40 moves along the guide rail 20, thereby lifting the workpiece. After the workpiece is lifted to the top of the destination position, the winch 51 is controlled to release the workpiece and move it downward, so that the workpiece can be placed stably, realizing the transfer of the workpiece and avoiding the space limitations of ground transportation.

[0027] A reel 60 is provided on the column 30, and a filter cloth 61 is wound on the reel 60. An electric cylinder body 70 is installed on the bracket 40. The electric cylinder body 70 can be connected to the filter cloth 61 through a connecting part 71. The filter cloth 61 includes a cloth body 611 and two belt bodies 612. The cloth body 611 is arranged between the two belt bodies 612. The connecting part 71 includes a cross bar 711 arranged on the movable rod of the electric cylinder body 70. Two sets of hooks 712 are provided on the cross bar 711, and hanging rings 713 are respectively provided on the two belt bodies 612.

[0028] After the workpiece is lifted upward, the hanging ring 713 is connected to the hook 712, and the electric cylinder body 70 is controlled to pull one end of the cloth body 611 upward, so that the cloth body 611 covers the bottom of the workpiece. The oil, debris, etc. contained in the workpiece are blocked by the cloth body 611 when dripping downward. The cloth body 611 is coated with a liquid-proof layer, so that the oil, debris and other debris cannot drip downward through the cloth body 611, thereby avoiding contamination of the passing path during transportation and affecting the use of other raw materials or equipment.

[0029] Example 2 provides a workpiece lifting device:

[0030] The base 10 and the guide rail 20 are both fixed to the ground. The base 10 is rotatably connected to the column 30, and a bracket 40 is provided on the column 30. A frame 50 is slidably connected to the bracket 40. A winch 51 is installed on the frame 50. The traction rope of the winch 51 is connected to a hook 52. By connecting the hook 52 to the lifting ear of the workpiece, the winch 51 is controlled to work, so that the workpiece can be pulled upward.

[0031] The bracket 40 is provided with a ball seat 41 embedded in the guide rail 20. The guide rail 20 is arc-shaped. The column rod 30 can rotate on the base 10 to drive the bracket 40 to rotate. The ball seat 41 on the bracket 40 moves along the guide rail 20, thereby lifting the workpiece. After the workpiece is lifted to the top of the destination position, the winch 51 is controlled to release the workpiece and move it downward, so that the workpiece can fall smoothly, realizing the transfer of the workpiece and avoiding the space limitations of ground transportation.

[0032] A reel 60 is provided on the column 30, and a filter cloth 61 is wound on the reel 60. An electric cylinder body 70 is installed on the bracket 40. The electric cylinder body 70 can be connected to the filter cloth 61 through a connecting part 71. The filter cloth 61 includes a cloth body 611 and two belt bodies 612. The cloth body 611 is arranged between the two belt bodies 612. The connecting part 71 includes a cross bar 711 arranged on the movable rod of the electric cylinder body 70. Two sets of hooks 712 are provided on the cross bar 711, and hanging rings 713 are respectively provided on the two belt bodies 612.

[0033] After the workpiece is lifted upward, the hanging ring 713 is connected to the hook 712, and the electric cylinder body 70 is controlled to pull one end of the filter cloth 61 to move upward, so that the cloth body 611 covers the bottom of the workpiece. The oil, debris, etc. contained in the workpiece are blocked by the cloth body 611 when dripping downward. The cloth body 611 is coated with a liquid-proof coating, so that the oil, debris, etc. cannot drip downward through the cloth body 611, thereby avoiding contamination of the passing path during transportation and affecting the use of other raw materials or equipment.

[0034] The cloth body 611 is concave downward, so that the blocked oil stains and debris are collected in the concave area. After the workpiece is lifted to the top of the target position, the electric cylinder body 70 is controlled to drive one end of the cloth body 611 to move downward, so that the collected oil stains and debris can slide down and be discharged to be collected separately.

[0035] The reel 60 is connected to a rotating handle 601. After the collected oil and debris are discharged from the cloth body 611, the connection with the hanging ring 713 and the hook 712 is cancelled. By operating the rotating handle 601, the filter cloth 61 is rolled up as a whole for the next use without affecting the placement of the workpiece.

[0036] A first motor body 11 is mounted on the base 10 . The first motor body 11 is rotatably connected to the column 30 via a gear set 12 , thereby providing power for the rotation of the column 30 .

[0037] The bracket 40 is provided with a screw rod 42 and a second motor body 43 for driving the screw rod 42 to rotate. The frame 50 is screwed to the screw rod 42 and can drive the frame 50 to move horizontally on the bracket 40 to adapt to the lifting of workpieces at different positions.
