[0029] like Figure 1 and Figure 2 As shown, an adjustable balance sling is mainly used for hoisting objects with circular shapes at the hoisting position, including a hoop body, at least two sliding components 4 are installed on the outer wall of the hoop body, and the sliding member 43 on the sliding component 4 can slide relative to the hoop body, and a lifting ear 5 is installed on the sliding member 43. When in use, the hoisting object can be clamped by the hoop body, and then the position of the lifting ear 5 is changed by rotating the sliding member 43. For irregular hoisting objects, the center of gravity of the hoisting position of the hoisting object can be adjusted by changing the position of the lifting ear 5, thereby ensuring the balance of the hoisting object, thereby greatly improving the hoisting efficiency and safety of the hoisting object.

[0030] In this embodiment, if Figure 3 and Figure 4As shown, the sliding assembly 4 includes an arc-shaped slide rail 41, an inner side wall of the arc-shaped slide rail 41 is provided with an arc-shaped protrusion 42, the arc-shaped protrusion 42 is installed on the outer side wall of the clamp body, and a sliding member 43 is slidably installed on the arc-shaped slide rail 41. In this embodiment, since the inner side wall of the arc-shaped slide rail 41 is provided with an arc-shaped protrusion 42, preferably, the arc-shaped protrusion 42 is located in the middle part of the inner side of the arc-centered slide rail, so that the upper and lower parts of the arc-shaped slide rail 41 both protrude the arc-shaped protrusion 42. That is to say, an upper slide rail is formed at the upper part of the arc-shaped slide rail 41, and a lower slide rail is formed at the lower part of the arc-shaped slide rail 41, and a lying T-shaped slide groove is opened on the sliding member 43. When the sliding member 43 is installed on the arc-shaped slide rail 41, the upper slide rail, the lower slide rail and the arc-shaped protrusion 42 are slidably installed in the lying T-shaped slide groove, thereby ensuring the reliability of the sliding installation of the sliding member 43 and the arc-shaped slide rail 41.

[0031] In this embodiment, if Figure 3 and 4 As shown, a driving component for driving the sliding member 43 to move along the arc-shaped slide rail 41 is installed on the sliding member 43, and a locking screw hole is opened on the outer wall of the sliding member 43, and a fastening screw 50 is installed in the locking screw hole. The position of the sliding member 43 on the arc-shaped slide rail 41 can be adjusted by the driving component. When the position of the sliding member 43 is adjusted, the position of the sliding member 43 can be fixed by tightening the fastening screw 50, thereby ensuring the reliability of the hoisting of the hoisted object.

[0032] In this embodiment, if Figure 5 As shown, the driving assembly includes a rotating shaft 47 with a rotating handle 44, and an axial hole is opened on the sliding member 43 from bottom to top. The rotating shaft 47 can be rotatable in the axial hole, and the rotating handle 44 is located below the sliding member 43. A penetrating accommodating hole 45 is opened on the outer wall of the sliding member 43, and a gear 46 is installed on the rotating shaft 47. A rack 49 meshing with the gear 46 is opened on the outer wall of the sliding member 43, and the rack 49 extends along the sliding direction of the sliding member 43. The gear 46 is located in the accommodating hole 45. The rotating shaft 47 is rotated by rotating the handle 44, so that the gear 46 rotates. After the gear 46 rotates, the gear 46 rolls along the extension direction of the rack 49, thereby realizing the movement of the sliding member 43 on the arc-shaped slide rail 41.

[0033] In this embodiment, if Figure 5As shown, an annular groove is provided on the rotating shaft 47, and a retaining spring 48 is provided in the annular groove. The gear 46 is located above the retaining spring 48, and the top of the rotating shaft 47 is rotatably installed in the shaft hole above the accommodating hole 45. By providing the retaining spring 48, the rotating shaft 47 has a stop function, that is, after the rotating shaft 47 is installed, the rotating shaft 47 will not fall off. Further, the rotating shaft 47 includes an upper shaft and a lower shaft. The upper shaft is rotatably installed in the shaft hole above the accommodating hole 45, and the lower shaft is rotatably installed in the shaft hole below the accommodating hole 45. A polygonal hole is provided at the bottom of the upper shaft, and a polygonal shaft matching the polygonal hole is provided at the top of the lower shaft. A through hole is provided to cooperate with the polygonal shaft, and the gear 46 is installed on the polygonal shaft of the lower shaft, and the top of the polygonal shaft cooperates with the polygonal hole. Therefore, when the handle 44 is rotated, the rotating shaft 47 can be driven to rotate, and the rotating shaft 47 can drive the gear 46 to rotate synchronously, thereby realizing the meshing and rolling of the gear 46 on the rack 49. During installation, the upper shaft is first installed in the upper shaft hole, and then the lower shaft is inserted from the bottom of the shaft hole. When the top of the lower shaft enters the accommodating hole 45, the gear 46 is installed on the polygonal shaft, and then the top of the polygonal shaft is matched with the polygonal hole of the upper shaft, and finally the retaining ring 48 is installed in the annular groove.

[0034] In this embodiment, if Figure 1 and Figure 2 As shown, the clamp body includes a first arc-shaped body 1 and a second arc-shaped body 2, one end of the first arc-shaped body 1 is hinged to one end of the second arc-shaped body 2, the other end of the first arc-shaped body 1 is connected to the other end of the second arc-shaped body 2 through a locking assembly 3, a sliding assembly 4 is installed on the outer side of the first arc-shaped body 1, and a sliding assembly 4 is also installed on the outer side of the second arc-shaped body 2. In this embodiment, the part to be clamped by the clamp body is a cylinder. Since the inner cavity of the cylinder is irregular, the center of gravity of the cylinder is not on the center line. When the clamp body clamps the cylinder, the position of the two groups of sliding assemblies 4 is changed, and then the lifting position is changed, thereby changing the center of gravity of the cylinder after lifting, and then facilitating the stable lifting of the cylinder.

[0035] In this embodiment, if Figure 6 and Figure 7As shown, the locking assembly 3 includes a locking block 31 and a pressing piece 37. The locking end of the first arc-shaped body 1 is hinged to the locking block 31 through a hinge shaft 32. The locking end of the second arc-shaped body 2 is provided with a convex portion 34 protruding outward, and a locking notch 36 is provided on the convex portion 34. A locking screw 33 is threadedly installed on the surface of the locking block 31 opposite to the convex portion 34. The locking end of the locking screw 33 passes through the locking notch 36. A split groove is provided on the locking end of the locking screw 33. The locking screws 33 at both ends of the split groove form a guide arm. The end of the locking end of the locking screw 33 is provided with a cam 35 through a pin shaft 39. The cam 35 A locking handle 38 is provided, and a guide hole matching the guide arm is opened on the pressing plate 37. The guide arm passes through the corresponding guide hole, and the pressing plate 37 is located between the cam 35 and the convex portion 34. When in use, the first arc body 1 and the second arc body 2 are first opened, and the hoisting object is placed between the first arc body 1 and the second arc body 2, and then the first arc body 1 and the second arc body 2 are surrounded, and finally the locking assembly 3 is locked. When the locking assembly 3 is locked, the locking screw 33 is first stuck in the locking notch 36, and then the locking screw 33 is rotated so that the locking screw 33 pulls the locking block 31, thereby making the first arc body The first arc body 1 and the second arc body 2 are brought closer, and then gradually hold the hoisting object. After the first arc body 1 and the second arc body 2 pre-hold the hoisting object, the cam 35 is rotated 90° by the locking handle 38, so that the cam 35 moves from the proximal end to the distal end, so that the cam 35 applies pressure to the pressing plate 37, and the pressing plate 37 moves relative to the locking screw 33, thereby further bringing the first arc body 1 and the second arc body 2 closer, thereby further holding the hoisting object, and the cam 35 rotates 90°, and the angle between the locking handle 38 and the locking screw 33 is about 90°, so that the locking screw 33 exerts pressure on the cam The reaction force applied by 35 will not cause the cam 35 to reset, that is, the cam 35 will always be in a locked state when there is no external force acting on it. When the hoisting of the hoisted object is completed and it needs to be unlocked, a thrust is applied to the locking handle 38 to move the cam 35 from the distal end to the proximal end, and then the locking screw 33 is loosened to achieve unlocking. In this embodiment, the distal end and the proximal end of the cam 35 have an angle of 90°, and the distal end of the cam 35 refers to the longest distance between the edge of the cam 35 and the center line of the pin shaft 39, while the proximal end of the cam 35 refers to the shortest distance between the edge of the cam 35 and the center line of the pin shaft 39.

[0036] In this embodiment, if Figure 2 As shown, a slot 7 is provided on the inner wall of the first arc-shaped body 1 and the second arc-shaped body 2, and an anti-skid pad 6 is installed in the slot 7. The anti-skid pad 6 is made of nylon material, and its surface is designed to be in the shape of a circular arc groove. It has good elasticity and can wrap the outer circle of the hoisting object when hoisting the hoisting object, making it difficult to slip and damage the hoisting object.

[0037] In this embodiment, if Figure 1 and Figure 2 As shown, locking screws 8 are installed at both ends of the first arc-shaped body 1 and the second arc-shaped body 2, and the sliding assembly 4 is located between the corresponding locking screws 8. When the hoisted object is clamped by the clamp body, the locking screws 8 are tightened to ensure that the relative positions of the first arc-shaped body 2, the second arc-shaped body 3 and the hoisted object are stable, thereby improving the reliability of the hoisting of the hoisted object.

[0038] In this embodiment, if Figure 4 As shown, scale lines are provided on the outer wall of the sliding member 43, and the scale lines can be used to quickly adjust the distance that the sliding member needs to slide, thereby facilitating the rapid determination of the position of the sliding member 43, thereby improving the hoisting efficiency of the hoisted object.
