[0032] like Figures 1 to 6 As shown, a sling tool comprises a sling 1;

[0033] A suspension rod 2, which is used to extend into the interior of the concrete block 3, and a plurality of suspension rods 2 are provided on the hanger 1;

[0034] The locking member 4 is arranged at one end of the suspension rod 2 extending into the concrete block 3, and the suspension rod 2 is rotatably arranged on the hanger 1, so that: after the suspension rod 2 extends into the reserved groove 31 of the concrete block 3, the suspension rod 2 is rotated to drive the locking member 4 to rotate synchronously so that it is buckled and fixed in the reserved groove 31.

[0035] This solution provides a new type of lifting tool, which greatly improves the lifting safety and lifting efficiency of the concrete block 3 by arranging a hanging rod 2 and a locking member 4 on the hanger 1 and pre-arranging a reserved groove 31 in the concrete block 3.

[0036] Specifically, before pouring the large concrete block 3, a reserved groove 31 for inserting the hanger 2 and the locking member 4 is reserved through template design. The retention of the reserved groove 31 will not affect the shape and strength of the concrete block 3. The hanger 1 is located above the concrete block 3, one end of the hanger 2 is fixed on the hanger 1, and the other end is just inserted into the reserved groove 31 reserved for the concrete block 3. There is a locking member 4 (which can be a locking iron shoe during actual lifting) under the hanger 2 that can withstand the weight of the concrete block. The locking member 4 can be fixed to the hanger 2 through a threaded pipe. The reserved groove 31 of the concrete block 3 is usually rectangular. After the locking member 4 is inserted along the reserved groove 31, the hanger 2 is rotated above the hanger 1, and the locking member 4 at the bottom of the hanger 2 is simultaneously rotated in the bottom direction, and the locking member 4 is stuck in the reserved groove 31 of the concrete, so that the hanger 1 and the concrete are lifted together, which has better stability and is safer during lifting.

[0037] Further, the reserved groove 31 includes a through groove 311 and a clamping groove 312 that penetrate each other, the through groove 311 is located above the clamping groove 312, and the width W1 of the through groove 311 is equal to the width W2 of the clamping groove 312, the length of the locking member 4 is less than the width W1 of the through groove 311, and the thickness D1 of the through groove 311 is less than the length of the locking member 4 and less than the thickness D2 of the clamping groove 312, so that:

[0038] After the locking member 4 passes through the through slot 311 and enters the locking slot 312 , the suspension rod 2 rotates 90°, and the locking member 4 turns and is buckled and fixed in the locking slot 312 .

[0039] The reserved groove 31 in the concrete includes two sections distributed up and down - a through groove 311 and a clamping groove 312, wherein the width of the suspension rod 2 and the locking portion are both smaller than the width of the through groove 311 and the clamping groove 312, so the suspension rod 2 and the locking portion can freely extend up and down; but the thickness of the through groove 311 is relatively small, and the thickness of the clamping groove 312 is relatively large, so after the suspension rod 2 and the locking portion extend into the clamping groove 312, the suspension rod 2 rotates 90 degrees in the forward or reverse direction so that the locking portion is perpendicular to the entry direction, and since the thickness of the clamping groove 312 is greater than the width of the locking portion and the width of the through groove 311, the locking portion will be firmly stuck in the clamping groove 312 to ensure that the concrete block 3 and the sling tooling are locked and fixed.

[0040] Furthermore, the length of the locking member 4 decreases gradually from top to bottom. The bottom end of the locking member 4 is smaller, which makes it easier for the locking member 4 to extend into the through slot 311 or the clamping slot 312 .

[0041] Furthermore, the hanger 1 comprises a first connecting rod 11, a second connecting rod 12, a third connecting rod 13 and a fourth connecting rod 14 connected end to end, the first connecting rod 11 and the third connecting rod 13 are arranged in parallel, and the second connecting rod 12 and the fourth connecting rod 14 are arranged in parallel;

[0042] The length of the first connecting rod 11 = the length of the third connecting rod 13 , the length of the second connecting rod 12 = the length of the fourth connecting rod 14 , and the length of the first connecting rod 11 > the length of the second connecting rod 12 .

[0043] like Figure 5 As shown, the lifting tool is used to make a balanced hanger 1 according to the reserved holes near the four corners of the concrete block 3. The hanger 1 includes four connecting rods, namely a first connecting rod 11, a second connecting rod 12, a third connecting rod 13 and a fourth connecting rod 14. It has better balance and stability, which is conducive to the lifting of large or heavy concrete blocks 3.

[0044] Of course, in other embodiments, the hanger 1 may be provided with more connecting rods to further improve its stability. Alternatively, the hanger 1 may also be a stable triangular structure, that is, the hanger 1 of this solution is composed of three connecting rods.

[0045] Furthermore, at least two suspension rods 2 are respectively disposed on the first connecting rod 11 and the third connecting rod 13 .

[0046] The first connecting rod 11 and the third connecting rod 13 are the long sides of the hanger 1, and the hanging rod 2 is arranged on the long sides of the hanger 1, which has better stability. At least two hanging rods 2 are arranged on the first connecting rod 11 and the third connecting rod 13, that is, there are four fixing points on the concrete block 3, which has better balance, and the concrete block 3 is not easy to move during the hoisting process, which further improves the safety during hoisting.

[0047] Furthermore, the hanger 1 is provided with a plurality of adjustment plates 15, each adjustment plate 15 corresponds to one of the hangers 2, an adjustment slot 151 is opened on the adjustment plate 15, an adjustment rod 152 is movably arranged in the adjustment slot 151, and the adjustment rod 152 passes through one end of the adjustment slot 151 and is connected to the hanger 2.

[0048] Due to errors and other reasons, the position of the reserved groove 31 of each batch of concrete blocks 3 may be different. In order to align the position of the hanger 2 with the reserved groove 31, an adjustment plate 15 including an adjustment groove 151 is provided on the hanger 1. The adjustment groove 151 is a long waist-shaped hole. The adjustment rod 152 can move forward and backward along the adjustment groove 151. Since the adjustment rod 152 is fixed to the hanger 2, the hanger 2 also moves synchronously when the adjustment rod 152 moves, so that the position of the hanger 2 and the reserved groove 31 is more consistent, which is convenient for fixing the concrete block 3.

[0049] Furthermore, a marking line 153 is further provided at the top of the adjusting rod 152, and the marking line 153 includes a first marking line and a second marking line, the first marking line and the second marking line are vertically intersected, and the length of the first marking line is greater than the length of the second marking line;

[0050] The first marking line is parallel to the length direction of the locking member 4 , and the second marking line is parallel to the width direction of the locking member 4 .

[0051] like Figure 6 As shown, by setting a marking line 153 on the adjusting rod 152 above the hanger 1, it is determined whether the hanger 2 is locked in place. The marking line 153 includes a first marking line (long line) and a second marking line (short line), and the two are in a cross shape. The marking line 153 corresponds to the length and width direction of the locking piece 4 at the bottom of the hanger 2. The first marking line corresponds to the length direction of the locking piece 4, and the second marking line corresponds to the width direction of the locking piece 4. The direction of the locking part can be known through the marking line 153 on the hanger 1.

[0052] Furthermore, the hanger 1 is provided with a plurality of lifting ears 16, and the lifting ears 16 are provided with lifting holes 161 for external lifting ropes to pass through. The hanger 1 is hoisted by the lifting ears 16, and the four corners of the hanger 1 can be provided with lifting ears 16. The lifting rope of the lifting equipment passes through the lifting holes 161 of the four lifting ears 16 on the hanger 1, and the balance is better, and the concrete block 3 can be better hoisted.

[0053] Furthermore, the outer wall of the suspension rod 2 is also provided with scale lines. In addition to the setting of the above-mentioned marking line 153, during the trial lifting / lifting process, the scale lines reserved on the suspension rod 2 can also be used to check whether the four suspension rods 2 are locked in place. After the suspension rod 2 is inserted into the concrete block 3, if the scale lines on the outside of the four suspension rods 2 remain consistent (a small error is allowed), it means that the insertion depth of all the suspension rods 2 is the same, which doubles the safety of the suspension tooling of this solution.

[0054] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
