Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a special hoisting tool for large upper roller boxes. Background Technology

[0002] In modern industrial production, large upper roller boxes are critical production components, requiring lifting and tilting operations during maintenance, repair, and replacement. However, existing lifting tools generally have many shortcomings when dealing with large upper roller boxes. Due to their typically enormous size and heavy weight, the structure and function of traditional lifting tools often cannot meet their specific lifting requirements. This not only leads to extremely inconvenient operation and consumes significant manpower and time costs, but more seriously, it may also cause safety accidents due to the instability and unreliability of the lifting equipment, posing potential threats to production and personnel.

[0003] Therefore, it is necessary to further explore and practice the above-mentioned technical issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a special lifting tool for large upper roller boxes. Through its unique structural design and innovative component combination, this lifting tool can safely, efficiently and conveniently complete the lifting and flipping of large upper roller boxes.

[0006] (II) Technical Solution

[0007] The technical solution adopted by this utility model to solve the above problems is:

[0008] A special lifting device for large upper roller boxes includes a lifting frame, and first lifting assemblies are provided on both sides of the lifting frame. The first lifting assembly includes a first chain and a connector. One end of the first chain is connected to the lifting frame, and the other end is connected to the connector. A buckle is provided on the end of the connector away from the first chain.

[0009] The gantry is also equipped with booms on both sides, and each boom has a second lifting assembly at both ends. The second lifting assembly includes a second chain and a hook. One end of the second chain is connected to the boom, and the other end is connected to the hook.

[0010] In the above technical solution, this hoisting component design enables stable lifting and fixing of the large upper roller box from multiple points, distributing the force and ensuring the stability of the large upper roller box during hoisting, reducing the risk of swaying and tilting.

[0011] Furthermore, the latch includes a first latching member, a second latching member, and an indexing pin, wherein both the first latching member and the second latching member are semi-circular rings;

[0012] One end of the first locking member is hinged to one end of the second locking member, and the other end of the first locking member is matched and connected to the other end of the second locking member through the indexing pin;

[0013] When the first locking member and the second locking member are closed together, the indexing pin cooperates with the first locking member and the second locking member to lock the first locking member and the second locking member.

[0014] In the above technical solution, this locking design can be tightly fixed to the corresponding part of the large upper roller box. The semi-circular locking part can better fit the shape of the object being lifted. The hinged structure with indexing pin makes the opening and closing operation of the locking convenient and the locking firm, effectively preventing the locking from loosening during the lifting process and improving the safety of the lifting.

[0015] Furthermore, the first and second locking components are provided with mounting grooves on their inner sides, and needle roller bearings are provided in the mounting grooves.

[0016] In the above technical solution, the needle roller bearing in the mounting groove can reduce the friction when the locking parts come into contact with the object being lifted, making the lifting and turning operations smoother, reducing the difficulty of operation, and reducing the wear on the surface of the object being lifted.

[0017] Furthermore, a lifting section is provided at the top of the hanger.

[0018] Furthermore, the hoisting part is equipped with lifting buckles.

[0019] Furthermore, a lifting ring is connected to the hook.

[0020] In the above technical solution, the cooperation between the lifting buckle and the lifting ring can further optimize the connection with the lifting equipment, make the connection more stable, reduce the risk of falling off during the lifting process, and ensure the safe and reliable operation of the lifting work.
