[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 In this embodiment of the present invention, a jib crane lifting assembly that is easy to assemble and disassemble includes a jib crane 1, and a lifting assembly 2 is provided at the end of the jib crane 1.

[0028] The boom crane 1 includes a rotating base 11, the upper end of which is fixedly connected to a mounting base 12. A boom 13 is mounted on the mounting base 12. A connector 14 is provided on the lower surface of the boom 13. A base telescopic electric cylinder 15 is connected to the connector 14. The other end of the base telescopic electric cylinder 15 is connected to the upper surface of the rotating base 11.

[0029] The upper surface of the boom 13 is regularly provided with multiple connecting blocks 16, each pair of connecting blocks 16 is formed, and each connecting block 16 is connected to a boom telescopic electric cylinder 17, the other end of each boom telescopic electric cylinder 17 is connected to a telescopic boom connector 18.

[0030] The telescopic boom connector 18 is provided on the telescopic boom 19, and each section of the telescopic boom 19 is provided with a telescopic boom connector 18; the telescopic boom 19 is provided on the boom 13, and the end of the telescopic boom 19 is provided with a hoisting component mounting seat 110, and the bottom of the hoisting component mounting seat 110 is provided with a connecting conical column 111.

[0031] By adopting the above technical solution, during hoisting, the extension of the base telescopic cylinder 15 first drives the boom 13 to rotate upward, and then the boom telescopic cylinder 17 connected to the upper surface of the boom 13 drives each telescopic arm 19 to extend outward to a suitable length. The angle is then selected by rotating the base 11, aligning the hoisting component mounting seat 110 with the target to be hoisted. The adjustability of the base telescopic cylinder 15 allows it to change its angle in the vertical plane. In some special building structure installation scenarios, such as hoisting and installing inclined roof beams or the extended structures of high-rise buildings, adjusting the angle of the boom 13 allows the hook to be more accurately aligned with the hoisting target, and also improves the hoisting and installation process. It allows for better control of the position and orientation of goods; the rotating base 11 allows the boom 13 to rotate 360° in the horizontal direction, meaning it can easily cover the entire circumference area from a fixed position; the boom telescopic cylinder 17 can change the working radius of the telescopic boom 19, allowing it to be flexibly adjusted according to the distance requirements of the lifting task. In open spaces, such as large logistics warehouses or open-pit mines, the telescopic boom 19 can be extended to lift goods that are far away from the boom 1. Conversely, in environments with limited space, such as indoor workshops or small warehouses, the telescopic boom 19 can be shortened to adapt to narrow spaces and accurately lift items that are close by.

[0032] In this embodiment, the connecting conical column 111 is connected to the hoisting component 21, and the hoisting component 21 has a conical groove 27 for installation inside it;

[0033] The lower surface of the hoisting component mounting base 110 is equipped with a clamping ring 22. The clamping ring 22 is arranged in a ring shape and has openings at both the upper and lower ends. The interior has a cavity 23. Four hydraulic cylinders 24 arranged in a ring array are installed in the cavity 23. The bottom of the hydraulic cylinder 24 is located on the outside of the clamping ring 22, and the other end is fixedly connected to the locking plate 25. The locking plate 25 has a protrusion 26.

[0034] By adopting the above technical solution, when installing the lifting assembly, the lifting component 21 is first initially connected to the connecting conical column 111 through the internal conical groove 27. At this time, the hydraulic cylinder 24 in the clamping ring 22 pushes the locking plate 25 to lock the lifting component 21. The coordinated action of multiple locking plates 25 achieves the clamping of the lifting component 21. When it is necessary to disassemble and replace the hook assembly, the hydraulic cylinder 24 is operated to drive the locking plate 25 to retract backward to complete the disassembly. The hydraulic system can provide high pressure, so the hydraulically driven clamping ring can generate huge clamping force, which can firmly fix the lifting component 21 and ensure that there will be no loosening during the lifting operation, thus ensuring the lifting safety. By simply operating the hydraulic cylinder 24, the clamping and loosening actions can be realized, without the need for cumbersome tightening and loosening operations like traditional bolt connections. This greatly improves the disassembly and assembly efficiency of the lifting assembly 2, and is especially suitable for lifting operation scenarios that require frequent disassembly and assembly.

[0035] The working principle of this utility model is as follows: During hoisting, the extension of the base telescopic electric cylinder 15 first drives the boom 13 to rotate upward. Then, the boom telescopic electric cylinder 17 connected to the upper surface of the boom 13 drives each telescopic arm 19 to extend outward to a suitable length. The angle is then selected by rotating the base 11, aligning the hoisting component mounting seat 110 with the target to be hoisted. The adjustability of the base telescopic electric cylinder 15 allows it to change its angle in the vertical plane. In some special building structure installation scenarios, such as hoisting and installing inclined roof beams or the extended structures of high-rise buildings, adjusting the angle of the boom 13 allows the hook to be more accurately aligned with the hoisting target. Furthermore, during hoisting and installation... It can better control the position and posture of the goods; the rotating base 11 can rotate so that the boom 13 can rotate 360° in the horizontal direction, which means that it can easily cover the entire circumference area around from a fixed position; the boom telescopic cylinder 17 can change the working radius of the telescopic boom 19, so that it can be flexibly adjusted according to the distance requirements of the lifting task. In open spaces, such as large logistics warehouses or open mines, the telescopic boom 19 can be extended to lift goods that are far away from the boom 1. Conversely, in environments with limited space, such as indoor workshops or small warehouses, the telescopic boom 19 can be shortened to adapt to narrow spaces and accurately lift items that are close at hand.

[0036] When installing the lifting assembly, the lifting component 21 is initially connected to the connecting tapered column 111 through the internal tapered groove 27. At this time, the hydraulic cylinder 24 in the clamping ring 22 pushes the locking plate 25 to lock the lifting component 21. The coordinated action of multiple locking plates 25 achieves the clamping of the lifting component 21. When it is necessary to disassemble and replace the hook assembly, the hydraulic cylinder 24 is operated to drive the locking plate 25 to retract backward to complete the disassembly. The hydraulic system can provide high pressure, so the hydraulically driven clamping ring can generate huge clamping force, which can firmly fix the lifting component 21 and ensure that there will be no loosening during the lifting operation, thus ensuring the lifting safety. By simply operating the hydraulic cylinder 24, the clamping and loosening actions can be realized, without the need for cumbersome tightening and loosening operations like traditional bolt connections. This greatly improves the disassembly and assembly efficiency of the lifting assembly 2, and is especially suitable for lifting operation scenarios that require frequent disassembly and assembly.
