DETAILED DESCRIPTION

[0023] A lifting platform with multi-degree-of-freedom positioning includes a frame 1, a lifting actuator 3, and a lifting system 2. The frame 1 includes two parallel outer frames 10, a folding beam 12, and a flange 11. The middle of the folding beam 12 is connected by the flange 11, and the ends of the folding beam 12 are respectively hinged on the two outer frames 10. By disconnecting the flange 11, the two outer frames 10 can be folded, reducing the occupied space and facilitating transportation. Longitudinal slide rails 13 are respectively provided on the outer frames 10, and sliders 14 are provided on the longitudinal slide rails 13. The sliders 14 are slidably connected to the longitudinal slide rails 13, and a connecting member 50 is provided on the slider 14. The connecting member 50 includes a flip seat 51, a longitudinal support lug 52, and a flip support lug 53. The lifting actuator 3 is a single-stage or multi-stage sliding telescopic rod, the upper end of which is connected to the outer frame 10, and the lower end of which is fixed to the wheel frame 40 on which the walking wheel 4 is installed. The lifting system 2 includes a sling 24, an auxiliary sling interface 25, a swing frame 22, a traverse frame 23, a tilt frame 21, a tilt actuator 20, a traverse actuator 27, a longitudinal actuator 29, a swing actuator 26, and a roll actuator 28. The sling 24 and the auxiliary sling interface 25 are mounted on the front and rear end faces of the swing frame 22, respectively. The sling 24 is hinged to the swing frame 22, and the auxiliary sling interface 25 is fixedly connected to the swing frame 22 via its mounting bracket 251. The roll actuator 28 is hinged to the sling 24 and the swing frame 22 at both ends. Its movement causes the sling 24 to rotate on the end faces of the swing frame 22. The rotation of the sling 24 controls the tilt angle of the hoisted object. The tilting frame 21 is positioned on either side of the swing frame 22 and is slidably connected to the transverse frame 23. A front pin 211 and a rear pin 212 are provided at the lower end of the tilting frame 21. The tilting seat 51 of the connector 50 is hinged to the tilting frame 21 via the front pin 211. One end of the tilting actuator 20 is hinged to the tilting frame 21 via the rear pin 212, while the other end is hinged to the slider via the tilting lug 53 of the connector 50. A connecting pin 231 is provided on the transverse frame 23, hinged to the swing frame 22 via the connecting pin 231. The transverse actuator 27 is hinged at both ends to the tilting frame 21 and the transverse frame 23, respectively. Its operation controls the movement of the transverse frame 23, causing the tilting frame 21 to slide relative to the swing frame 22, thereby controlling the distance the tilting frame 21 extends beyond the swing frame 22, thereby achieving transverse positioning adjustment of the sling 24. The two ends of the swing actuator 26 are hinged to the swing frame 22 and the traverse frame 23, respectively. The swing actuator 26 controls the relative rotation of the traverse frame 23 and the swing frame 22, driving the sling 24 to achieve the swing function. The longitudinal actuator 29 is hinged to the outer frame 10 at one end and to the slider 14 at the other end via the longitudinal support lug 52. Its movement drives the entire lifting system 2 to achieve longitudinal movement relative to the frame 1.

[0024] The method for hoisting positioning adjustment includes one or more of the following steps:

[0025] A. Height adjustment: Start the lifting actuator 3 to raise and lower the height of the frame 1;

[0026] B. Lateral adjustment: Activate the lateral actuator 27 to adjust the lateral distance between the turnover frame 21 and the swing frame 22;

[0027] C. Longitudinal adjustment: Activate the longitudinal actuator 29 to control the position of the slider 14 on the longitudinal rail 13, and adjust the longitudinal relative position of the lifting system 2 and the frame 1;

[0028] D. Swing adjustment: Start the swing actuator 26 to make the traverse frame 23 and the swing frame 22 rotate relative to each other, and adjust the relative angle between the traverse frame 23 and the swing frame 22;

[0029] E. Roll adjustment: Activate the roll actuator 28 to adjust the relative angle between the sling 24 and the swing frame 22;

[0030] F Flip adjustment: Start the flip actuator 20 to adjust the relative angle between the lifting system 2 and the frame 1.

[0031] During operation, the height is first adjusted according to the placement height of the heavy object, and the outer frame 10 is driven up and down by the lifting actuator 3 to complete the height positioning of the lifting system 2, and the lifting system 2 is moved above the heavy object. When there is a lateral deviation between the heavy object and the lifting system 2 (that is, the lifting point of the sling and the lifting point of the heavy object), it is necessary to perform lateral fine-tuning before lifting. The lateral actuator 27 is used to make the flip frame 21 and the swing frame 22 produce relative movement, so that the sling 24 installed on the swing frame 22 (and the auxiliary sling installed on the auxiliary sling interface 25) changes its relative position with the heavy object as the lateral position of the swing frame 22 changes, thereby achieving lateral positioning adjustment of the sling 24. When there is a longitudinal deviation between the heavy object and the lifting system 2, the longitudinal actuator 29 is activated. The longitudinal actuator 29 causes the slider 14 to slide on the longitudinal slide rail 13, driving the lifting system 2 to slide back and forth on the longitudinal slide rail 13 for positioning, thereby completing the longitudinal positioning adjustment of the sling 24 relative to the heavy object. When the object has an angular deviation from the lifting system 2, the swing actuator 26 drives the swing frame 22 and the sling 24 thereon to complete a multi-angle swing on the transverse frame 23, achieving the swing positioning adjustment of the sling 24. When there is a certain angular deviation between the lifting point of the object and the lifting point of the sling 24, the roll actuator 28 causes the sling 24 to rotate at multiple angles on the swing frame 22, achieving its roll positioning adjustment and ensuring the connection between the sling 24 and the object. After the object is lifted, it is moved to the drop point. If the object needs to be flipped, the flip actuator 20 causes the lifting system 2 to rotate at multiple angles around the rear pin 212, thereby achieving the rotation and flipping of the object to meet the required drop angle.
