Description

Technical Field

[0001] This utility model relates to the field of boom assembly technology, specifically a lightweight mechanical boom assembly. Background Technology

[0002] Lightweight crane boom assemblies represent a significant innovation direction in modern construction machinery. Their core objective is to reduce the boom assembly's weight while maintaining structural strength and functionality, through material optimization, structural design, and improved manufacturing processes, thereby enhancing the overall performance of the equipment. Reduced boom weight increases the equipment's effective load capacity, enabling the lifting of heavier objects under the same power conditions. Lightweight design also reduces energy consumption during operation, aligning with industry trends towards energy conservation and emission reduction.

[0003] In existing technologies, such as the high-strength jib assembly for tower cranes disclosed in CN217051401U, the components include a tower top, jib, jib trolley, high-strength structural component, counterweight, tower body, and tower base. The high-strength structural component includes a support platform, fixed connectors, fastening frames, connecting rods, crossbars, reinforcing ribs, and snap-fit ​​blocks. The support platform is fixed to the upper surface of the fixed connectors, and the fastening frames are also fixed to the upper surface of the fixed connectors. The support platform and fastening frames are fixed together by connecting rods, and the snap-fit ​​blocks are fixed to the upper surface of the support platform. The high-strength structural component can assist in the installation and fixation of the jib and tower body. Its frame structure disperses the lever pressure on the jib, reducing local pressure at the connection between the jib and tower body. It has a simple structure, is easy to install, and improves the stability of the jib and tower body during operation.

[0004] The existing frame structure of the boom assembly can distribute the lever pressure on the boom, reduce the local pressure at the connection between the boom and the tower, and improve the stability of the boom and the tower during operation. However, it has poor protection effect and is not convenient for maintenance and repair of the boom assembly. Utility Model Content

[0009] The fixing mechanism includes four connectors, all of which are welded to both ends of the first fixing frame. Each of the four connectors has a fixing rod inserted into its interior, and a guardrail is welded to the upper surface of the fixing rod.

[0010] As a further improvement of this utility model, the side walls of the four connecting members are each equipped with fixing bolts that abut against the fixing rod.

[0011] As a further improvement of this utility model, two reinforcing rods are symmetrically welded to the inner wall of the second fixing frame.

[0012] As a further embodiment of this utility model: the reinforcing mechanism includes connecting rods, and there are several connecting rods. Each of the several connecting rods is welded to the lower surface of the second fixed frame, and a connecting plate is welded and fixed to the lower surface of the connecting rod.

[0013] As a further improvement of this utility model, a connecting block is fixed to one end of the connecting plate.

[0014] As a further embodiment of this utility model: a fixing seat is welded to one end of the second fixing frame, and a fixing plate is welded to the other end of the second fixing frame.

[0015] As a further improvement of this utility model: a limiting hole is provided inside the fixing plate, and a limiting bolt that is threadedly connected to the fixing seat is inserted into the limiting hole.

[0016] As a further improvement of this utility model: an auxiliary frame is welded to one end of the first fixing frame, and an auxiliary connecting seat is fixed to one end of the auxiliary frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 2. The present invention enhances the overall strength of the component by providing reinforcing rods on the second fixed frame, and provides connecting rods to give the boom a stronger lifting capacity. The connecting blocks on the connecting plates can connect and fix the two connecting plates, thereby ensuring stability. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figures 1-5 This is the first embodiment of the present invention.

[0031] This embodiment provides a lightweight mechanical boom assembly, including a first fixed frame 1, a second fixed frame 2 welded and fixed to the lower surface of the first fixed frame 1, an anti-slip pedal 3 welded and fixed to the upper surface of the first fixed frame 1, a fixing mechanism for fixing the assembly on the outer wall of the first fixed frame 1, and a reinforcing mechanism for reinforcing the assembly on the lower surface of the second fixed frame 2.

[0032] The fixing mechanism includes four connectors 4. All four connectors 4 are welded to both ends of the first fixing frame 1. Fixing rods 41 are inserted into the interior of each of the four connectors 4. A guardrail 42 is welded to the upper surface of the fixing rods 41.

[0033] Specifically, the side walls of the four connectors 4 are each fitted with fixing bolts 43 that abut against the fixing rod 41.

[0034] Furthermore, the first fixed frame 1 is equipped with an anti-slip footboard 3, which facilitates maintenance personnel to walk on the first fixed frame 1, thereby facilitating subsequent maintenance of the boom assembly.

[0035] Specifically, the inner wall of the second fixing frame 2 is symmetrically welded with two reinforcing rods 5.

[0036] Furthermore, the overall strength of the component can be enhanced by the reinforcing rod 5 provided on the second fixing frame 2.

[0037] In use, first assemble the first fixed frame 1 and the second fixed frame 2 into the appropriate positions. The first fixed frame 1 is equipped with an anti-slip footboard 3, which facilitates the movement of maintenance personnel on the first fixed frame 1, thereby facilitating subsequent maintenance of the boom assembly. The connecting part 4 is equipped with a fixing rod 41, which, together with the guardrail 42, can play a protective role, thereby improving the safety of maintenance personnel when walking on the anti-slip footboard 3. By unscrewing the fixing bolt 43 on the connecting part 4, the fixing of the fixing rod 41 can be released, so that the guardrail 42 can be disassembled for easy use. The reinforcing rod 5 provided on the second fixed frame 2 can enhance the overall strength of the assembly.

[0038] In summary, when using this lightweight mechanical boom assembly, the anti-slip footboard 3 on the first fixed frame 1 facilitates the movement of maintenance personnel on the first fixed frame 1, thereby making subsequent maintenance of the boom assembly easier. Furthermore, the connecting piece 4 is equipped with a fixing rod 41, which, in conjunction with the guardrail 42, provides protection, thereby improving the safety of maintenance personnel when walking on the anti-slip footboard 3. By unscrewing the fixing bolts 43 on the connecting piece 4, the fixing rod 41 can be released, allowing the guardrail 42 to be disassembled.

[0039] Example 2:

[0040] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0041] Specifically, the reinforcing mechanism includes connecting rods 6, and there are several connecting rods 6. All connecting rods 6 are welded to the lower surface of the second fixed frame 2, and a connecting plate 61 is welded and fixed to the lower surface of the connecting rods 6.

[0042] Furthermore, the connecting rod 6 further enhances the lifting capacity of the boom.

[0043] Specifically, a connecting block 62 is fixed to one end of the connecting plate 61, a fixing seat 7 is welded to one end of the second fixing frame 2, and a fixing plate 8 is welded to the other end of the second fixing frame 2.

[0044] Furthermore, the connecting block 62 provided on the connecting plate 61 can be used to connect and fix the two connecting plates 61 together.

[0045] Specifically, a limiting hole 9 is provided inside the fixing plate 8, and a limiting bolt 10 that is threadedly connected to the fixing seat 7 is inserted into the limiting hole 9.

[0046] Furthermore, the limiting bolts 10 are inserted into the limiting holes 9 to fix the multiple second fixing brackets 2 together.

[0047] Specifically, an auxiliary frame 11 is welded to one end of the first fixed frame 1, and an auxiliary connecting seat 12 is fixed to one end of the auxiliary frame 11.

[0048] Furthermore, through the auxiliary frame 11, under the action of the auxiliary connecting seat 12, external drive equipment can be connected and fixed to the boom assembly for convenient use.

[0049] In use, multiple sets of first fixed frames 1 and second fixed frames 2 can be connected through the fixed seat 7 set on the second fixed frame 2 and with the cooperation of the fixed plate 8. Tightening the limiting bolt 10 on the fixed seat 7 allows the limiting bolt 10 to be inserted into the limiting hole 9, thereby fixing multiple second fixed frames 2 together and effectively preventing them from falling off. The connecting rod 6 provides the boom with stronger lifting capacity. The connecting block 62 set on the connecting plate 61 can connect and fix two connecting plates 61 together, thereby ensuring stability. Through the auxiliary frame 11, with the help of the auxiliary connecting seat 12, external drive equipment can be connected and fixed to the boom assembly for convenient use.

[0050] In summary, when using this lightweight mechanical boom assembly, the anti-slip footboard 3 on the first fixed frame 1 facilitates the movement of maintenance personnel on the first fixed frame 1, thereby facilitating subsequent maintenance of the boom assembly. Furthermore, the connecting piece 4 is equipped with a fixing rod 41, which, in conjunction with the guardrail 42, provides protection, thus improving the safety of maintenance personnel walking on the anti-slip footboard 3. By unscrewing the fixing bolts 43 on the connecting piece 4, the fixing rod 41 can be released, allowing the guardrail 42 to be disassembled. The connecting rod 6 further enhances the boom's lifting capacity. The connecting block 62 on the connecting plate 61 connects and secures the two connecting plates 61, ensuring stability.
