[0039] The following combines with the attached drawings to illustrate the specific embodiments of the present utility model.

[0040] The structure and function of the present utility model are as follows:

[0041] As Figures 1-7 shown, a high-load multi-functional lifting tool includes a hoisting body 3 in a cylindrical shape. A plurality of first booms 1 are evenly spaced along the circumference on the outer circumferential surface of the hoisting body 3. A pulley mechanism 5 is cooperatively installed on a single first boom 1. A connection seat 10 is cooperatively installed at the bottom of a single pulley mechanism 5. A second boom 2 is cooperatively installed at the bottom of a single connection seat 10. The installation position of a single second boom 2 on the corresponding first boom 1 is adjusted through the corresponding pulley mechanism 5. Boom mechanisms 6 are cooperatively installed at both ends of a single second boom 2 respectively. The boom mechanism 6 is used to hook the workpiece. By setting the pulley mechanism 5, the installation position of the second boom 2 on the corresponding first boom 1 can be quickly adjusted, so that the lifting tool can be applicable to workpieces of various sizes, improving the use flexibility and compatibility; by setting a plurality of boom mechanisms 6, the workpiece can be stably hooked, reducing workpiece deformation and improving product quality.

[0042] The length direction of a single first boom 1 is perpendicular to the length direction of the corresponding second boom 2. By setting the mutually perpendicular first boom 1 and second boom 2, the structural form of the traditional lifting tool is improved. Based on the adjustable boom (including the first boom 1, pulley mechanism 5, connection seat 10 and connection pin 12), a small boom (i.e., the second boom 2) is added. By hanging the vertical boom mechanisms 6 at both ends of the small boom, the arrangement quantity of the boom mechanisms 6 is increased. When the lifting tool is operating, the lifting stress points of the workpiece are increased, improving the safety and stability of the lifting process, effectively reducing workpiece deformation and improving the load capacity of the lifting tool.

[0043] The single first lifting arm 1 is made of I-beam, so that grooves 11 are formed on the two side end faces of the first lifting arm 1. The two grooves 11 are symmetrically distributed. Several first ribs 8 are arranged at intervals on the bottom end face of the first lifting arm 1, and a first pin slot 9 is formed between two adjacent first ribs 8. There are two grooves 11 arranged on each first lifting arm 1, and the two grooves 11 respectively correspond to two sets of sliding wheel groups in the pulley mechanism 5 installed on the first lifting arm 1; each set of sliding wheel groups is embedded in the corresponding groove 11 and can roll along the groove 11, so as to facilitate the pulley mechanism 5 to adjust the installation position of the second lifting arm 2 on the first lifting arm 1;

[0044] As Figure 3 shown, the first pin slot 9 corresponds to the locking pin 503 on the pulley mechanism 5. When the locking pin 503 is inserted into the first pin slot 9, the corresponding pulley mechanism 5 can be limited, so that the pulley mechanism 5 is locked on the corresponding first lifting arm 1.

[0045] As Figures 5-7 shown, the structure of a single pulley mechanism 5 is as follows: it includes an installation plate group. The installation plate group includes two installation plates 502 arranged at intervals opposite to each other. The two installation plates 502 are fixedly connected by several first pin shafts 504. A sliding wheel group is rotatably installed on the inner side end face of a single installation plate 502. A single set of sliding wheel groups includes several sliding wheels 501; the two sets of sliding wheel groups respectively correspond to the grooves 11 on both sides of the corresponding first lifting arm 1. By embedding the sliding wheel group into the corresponding groove 11, the sliding wheel group can rotate in the corresponding groove 11; a second pin shaft 505 is detachably installed on the installation plate group, and the second pin shaft 505 is used for cooperative installation with the corresponding connecting seat 10; locking pins 503 are respectively installed at both ends of the installation plate group, and the locking pins 503 correspond to the first pin slot 9. By inserting the locking pins 503 into the first pin slot 9, the pulley mechanism 5 is limited. The sliding wheel group is limited by the installation plate group and the first pin shaft 504 to prevent it from slipping out of the corresponding groove 11 and ensure the movement stability of the pulley mechanism 5;

[0046] A single connecting seat 10 is rotatably installed on the outer circumferential surface of the corresponding second pin shaft 505. A single connecting seat 10 is cooperatively installed with the corresponding second lifting arm 2 through a connecting pin 12. The connecting pin 12 is arranged parallel to the corresponding second pin shaft 505 and is located below the corresponding pin shaft 505.

[0047] The single second lifting arm 2 is made of I-beam. An array of rib groups is arranged on the top end face of the second lifting arm 2. A single set of rib groups includes two second ribs 13 arranged at intervals. A second pin slot 14 is formed between the two second ribs 13. An installation rib plate is arranged at the top of the single second lifting arm 2. A through hole is opened on the end face of the installation rib plate, and the connecting pin 12 passes through the through hole, so as to realize the cooperative installation between the corresponding second lifting arm 2 and the corresponding connecting seat 10;

[0048] The second pin slot 14 corresponds to the second pin rod 602. By clamping the second pin rod 602 into the second pin slot 14, the hanging rod mechanism 6 is fixed to the corresponding second boom 2. In addition, by arranging multiple groups of rib groups at intervals along the length direction of the second boom 2, it is convenient to adjust the installation position of the hanging rod mechanism 6 on the corresponding second boom 2, so that the spreader can further accommodate workpieces of multiple sizes and improve its use flexibility.

[0049] As Figure 4 shown, the structure of a single hanging rod mechanism 6 is as follows: it includes a suspension plate group. The suspension plate group includes two suspension plates 603 arranged at intervals relatively. The two suspension plates 603 are cooperatively connected by a first pin rod 601 and a second pin rod 602 arranged at intervals. The suspension plate group is cooperatively installed with the hanging rod 604 through the first pin rod 601. The second pin rod 602 corresponds to the second pin slot 14. By clamping the second pin rod 602 into a second pin slot 14 on the corresponding second boom 2, the hanging rod mechanism 6 is limited. A hook 605 is arranged at the end of the hanging rod 604. The hook 605 and the hanging rod 604 form an L-shaped structure, so as to hook the workpiece through the L-shaped structure. The hanging rod 604 is cooperatively installed on the outer circumferential surface of the first pin rod 601. The hanging rod 604 and the hook 605 adopt an integral structure.

[0050] A hoisting end face 606 is arranged on a single hook 605. The hoisting end face 606 is flat. When a single hanging rod mechanism 6 hooks the workpiece, the hoisting end face 606 on the corresponding hook 605 contacts the bottom wall surface of the workpiece, and the inner side wall surface of the corresponding hanging rod 604 contacts the outer side wall surface of the workpiece. By arranging the hoisting end face 606, the workpiece can be stably supported, so as to avoid deformation of the workpiece.

[0051] Several reinforcing rib plates 7 are arranged between the side wall surface of a single first boom 1 and the spreader body 3. The reinforcing rib plates 7 are used to improve the structural strength and stability of the spreader.

[0052] A lifting lug 4 is arranged at the top of the spreader body 3. The lifting lug 4 is used to connect with the output end of the hoisting machinery, which is convenient for the hoisting machinery to lift the spreader for hoisting operations.

[0053] The working process of the present utility model is as follows:

[0054] During hoisting operations, the spreader is connected to the output end of the hoisting machinery through the lifting lug 4;

[0055] Then, the installation position of the second boom 2 on the corresponding first boom 1 can be adjusted through the pulley mechanism 5 so that the spreader can match the size of the workpiece, or the installation position of the hanging rod mechanism 6 on the second boom 2 can be adjusted so that the spreader can match the size of the workpiece;

[0056] After the adjustment is completed, the workpiece is simultaneously hooked by the suspension rod mechanism 6, and then the hoisting machine drives the workpiece to move through the lifting tool to transport the workpiece to the target position.

[0057] The above description is an explanation of the present utility model, not a limitation thereof. The scope defined by the present utility model is referred to the claims. Any form of modification can be made within the protection scope of the present utility model.
