Description
Technical Field
[0001] This utility model relates to the field of cranes, specifically to a double-girder crane. Background Technology
[0002] A European-style double-girder crane (application number: CN202111039548.3) has been proposed in China. It includes two support frames and two crossbeams. Each crossbeam has a first sliding groove on its side wall. A first drive motor unit is movably arranged between the two first sliding grooves. A bearing block is movably arranged on the lower end face of the first drive motor unit. The bearing block is equipped with a hook mechanism for lifting goods and an auxiliary support mechanism for adjusting the position of the hook mechanism. This invention utilizes the cooperation of the support arm, the first fixed pulley, and the hydraulic push rod. When the telescopic end of the hydraulic push rod extends, it can push the second connecting lug and the slider to move on the moving groove, thereby expanding the support arm outward and increasing the distance between the two lifting cables. This allows the crane to lift and transfer large-volume goods while ensuring the stability of the goods during the lifting and transfer process. Furthermore, the two lifting cables further reduce the swaying of the goods during lifting.
[0003] The existing crane's side plates and contact points have a relatively fixed connection method, which cannot achieve multi-dimensional flexible adjustment and limits the crane's performance in complex spatial environments. Therefore, there is a need for a new type of double-girder crane with a reasonable structure, flexible adjustment, and strong stability to solve the above problems. Summary of the Invention

[0020] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings. Example 1
[0021] like Figure 1-3 As shown, this utility model provides a double-girder crane, including two side plates 1, a support beam 5 is provided on the top of the two side plates 1, an extension plate 2 is provided on the outside of the side plates 1, a threaded rod 3 is provided through the outside of the extension plate 2, and an adjustment plate 4 is provided at the bottom of the threaded rod 3.
[0022] There are two support beams 5. A mover 6 is provided on the top of the support beam 5. A lifting controller 7 is provided on the top of the mover 6. A rotating wheel 8 is provided on the outside of the lifting controller 7. A lifting block 9 is provided below the mover 6.
[0023] This utility model features a threaded rod 3 and an adjusting plate 4 working together on the outside of the side plate 1. By rotating the threaded rod 3, the height of the side plate 1 can be precisely controlled. This not only improves the adjustability of the overall structure but also effectively enhances the stability of the side plate 1, ensuring the robustness and reliability of the entire support system and improving the safety and reliability of equipment operation. Example 2
[0024] like Figure 1-2 As shown, a slide rail 101 is provided on the top of the side plate 1, and a moving wheel 504 is provided on the bottom of the support beam 5. The slide rail 101 and the moving wheel 504 cooperate with each other.
[0025] Specifically, this structure allows the support beam 5 to move on the side plate 1 via the moving wheel 504.
[0026] In this embodiment, the extension plate 2 is fixedly connected to one side of the side plate 1. The top of the extension plate 2 is provided with a threaded hole, and the threaded rod 3 is threaded through and connected to the threaded hole. The top of the threaded rod 3 is provided with a rotating plate 301, and the top of the adjusting plate 4 is provided with a rotating block 401. The bottom of the threaded rod 3 is rotatably connected to the inside of the rotating block 401.
[0027] Specifically, the extension plate 2 is used to support the threaded rod 3. After the threaded rod 3 is rotated, it can drive the adjusting plate 4 to rise and fall, thereby controlling the height of the adjusting plate 4. When the height of the adjusting plate 4 is lower than the height of the side plate 1, the adjusting plate 4 can be used for support. A fixing structure can be set at the connection between the extension plate 2 and the threaded rod 3 to prevent the threaded rod 3 from sliding when it is stationary, thus ensuring the stability of the adjusting plate 4.
[0028] In this embodiment, a beam connecting rod 501 is provided between the two support beams 5, a support rail 502 is provided on the outside of the support beam 5, and a slide rail 503 is provided on the top of the support beam 5. Example 3
[0029] like Figure 3 As shown, the bottom of the mover 6 is fixedly connected to at least two symmetrically distributed moving motors 601. The output end of the moving motor 601 is provided with a second moving wheel 602, and the second moving wheel 602 cooperates with the second slide rail 503.
[0030] Specifically, this structure, in conjunction with slide rail 503, allows for convenient control of the movement of the mover 6 when the moving motor 601 is started.
[0031] In this embodiment, the lifting controller 7 is fixedly connected to the top of the mobile device 6, a lifting adjustment motor 701 is provided on the outside of the lifting controller 7, the output end of the lifting controller 7 is connected to the rotating wheel 8, and a height rope 801 is provided on the outside of the rotating wheel 8.
[0032] In this embodiment, the top of the lifting block 9 is provided with a lifting wheel 901, the lifting wheel 901 is connected to the height rope 801, and the bottom of the lifting block 9 is provided with a hook 902.
[0033] Specifically, the moving motor 601 at the bottom of the mover 6 can be used to easily control the movement of the mover 6, and the lifting controller 7, together with the rotating wheel 8, can adjust the height of the lifting block 9. The height of the object connected to the hook 902 can be adjusted by rotating the height rope 801.
[0034] In summary, by setting up the side plate 1 and the support beam 5 in cooperation, and then setting up the mover 6, the position of the mover 6 can be adjusted forward, backward and left and right. Combined with the adjustment function of the lifting controller 7, multi-dimensional and high-precision positioning and support of the object can be achieved.
[0035] A threaded rod 3 is provided on the outside of the side plate 1 in conjunction with an adjusting plate 4. The height of the adjusting plate 4 can be controlled by rotating the threaded rod 3, thereby adjusting the height of the side plate 1. At the same time, the stability of the side plate 1 can be ensured, thus ensuring the firmness of the support structure.
[0036] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
