Different building structures vary, and climbing tower crane models are diverse, each with different requirements for the compatibility of the tool beam.

[0003] However, in the existing technology, the tool beams of climbing tower cranes are mostly customized designs with fixed dimensions and structures, making it difficult to adapt to the usage requirements of different building structures and different crane models. Customized tool beams have long processing cycles, and due to their limited adaptability, they are difficult to reuse after completing a specific project. This not only increases the cost of use but also wastes resources, failing to meet the needs of efficient and economical construction. Utility Model Content

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 - Figure 4 As shown, an adjustable beam structure for a tower crane tool beam is provided, including a tool beam body 1. The tool beam body 1 includes a wall connection section 2. One end of the wall connection section 2 is connected to a stirrup section 3. The end of the stirrup section 3 away from the wall connection section 2 is connected to a stirrup connection section 4. The end of the stirrup connection section 4 away from the stirrup section 3 is connected to a second stirrup section 5. The end of the second stirrup section 5 away from the stirrup connection section 4 is connected to a strut connection section 6 and the wall connection section 2. Several strut bodies 7 are detachably connected to the outside of the strut connection section 6. This allows the various components of the tool beam to be flexibly combined and adjusted. It can achieve the conversion between cantilever and cross-beam tool beams by replacing the strut connection section 6 and the wall connection section 2. It can also adapt to different building structures and tower crane models based on each connection section, without the need for customized production, thus improving adaptability.

[0022] In this example, a pair of ear plates 8 are symmetrically provided on the bottom surface and the front and rear sides of the strut connecting section 6. The side walls of the ear plates 8 are symmetrically provided with connection holes. Each pair of ear plates 8 is hinged to one end of the strut body 7, and one end of the strut body 7 is located between the two ear plates 8. Through the hinge structure of the ear plates 8, the strut body 7 and the strut connecting section 6 can be stably connected. At the same time, it provides a certain installation and adjustment space for the strut body 7, which is convenient to adjust the strut angle according to the actual force requirements and improve the overall stability of the tool beam.

[0023] In this example, the main body of the strut 7 includes a strut head 1 9 and a strut head 2 10. One end of the strut head 1 9 or the strut head 2 10 is hinged to an ear plate 8 provided on one side of the strut connecting section 6. The strut head 1 9 and the strut head 2 10 are connected by several strut segments 11. With the help of the combination structure of the strut head 1 9, the strut head 2 10 and the strut segments 11, the number of strut segments 11 can be increased or decreased according to actual needs, and the length of the main body of the strut 7 can be flexibly adjusted to adapt to the support requirements of different spacings, avoiding the adaptation limitations caused by fixed dimensions.

[0024] In this example, several fixing blocks 13 are symmetrically arranged on the outer walls of both ends of the strut segment 11. Fixing blocks 12 are symmetrically arranged on the outer side of the inner side of the strut head 19 and the strut head 20, and fixing blocks 12 and fixing blocks 23 correspond to each other. Fixing blocks 12 and fixing blocks 23 on the side near fixing blocks 12 are connected by bolts. The fixing blocks 23 installed at the ends of adjacent strut segments 11 are fixedly connected by bolts. The fixing blocks 12 at one end of the strut head 20 and fixing blocks 23 on the side near fixing blocks 12 are connected by bolts. The bolt connection between fixing blocks 12 and fixing blocks 23 can ensure the stable connection of each component of the strut body 7, facilitate disassembly and adjustment, and make it convenient to replace or add or remove strut segments 11 in the future, reducing maintenance and adjustment time and improving efficiency.

[0025] In this example, both the first strut head 9 and the second strut head 10 are composed of a cylindrical structure and a semi-circular plate structure, and the side wall of the semi-circular plate structure is provided with a fixing hole. The cylindrical structure facilitates the connection with the strut section 11, while the semi-circular plate structure and fixing hole can improve the connection stability with the ear plate 8 or other components, avoid damage caused by uneven force on the connection part, and extend the service life of the strut body 7.

[0026] In this example, the lengths of the strut segments 11 are 1m, 0.5m, or 0.3m. By providing strut segments 11 of various lengths, the required strut length can be precisely assembled without the need for additional custom-made strut components of special lengths, reducing processing time and costs, while improving the fitting accuracy of the strut body 7 and meeting the support length requirements in different scenarios.

[0027] During use, the tool beam body 1 can be adjusted in multiple sections to adapt to foundation requirements: adjusting the length of the wall connection section 2 can change the distance between the tower crane and the wall to adapt to the building space; adjusting the length of stirrup section 1 3, stirrup connection section 4, and stirrup section 2 5 can adapt to wall shrinkage and the installation parameters of different models of tower cranes, ensuring foundation compatibility.

[0028] The tool beam can be used in different ways by changing its structure: when the stirrup section 2 5 is connected to the support rod at one end of section 6, it is a cantilever structure; when it is replaced with the wall connection section 2, it is a cross-beam structure, which can flexibly adapt to different working scenarios.

[0029] The strut connecting section 6 works with the strut body 7 to achieve support adjustment: the ear plate 8 of the strut connecting section 6 is hinged to the strut body 7 through the connecting hole to ensure a stable connection; the strut head 1 9, strut head 2 10 and strut section 11 of the strut body 7 are connected to the strut section 11 by fixing block 1 12 and fixing block 2 13. By selecting strut sections 11 of 1m, 0.5m and 0.3m and adjusting the number, the strut body 7 of the required length can be assembled to provide stable support.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
