[0002] Tower cranes are commonly used lifting equipment in construction, and their standard sections are the main supporting structure. Existing tower crane standard sections mostly adopt integral welded or bolted connections, resulting in large size and heavy weight. Transportation is constrained by highway width and height restrictions, leading to high transportation costs and low efficiency. Furthermore, the installation and dismantling processes are complex, requiring large lifting equipment and resulting in long construction periods. While some detachable standard sections exist, their connection structures are often unstable, and their folding designs are imperfect, affecting safety and convenience of use. Therefore, there is an urgent need for a tower crane standard section that is easy to transport, install, and dismantle to solve the above problems. Utility Model Content

[0003] This invention overcomes the shortcomings of existing technologies and provides a detachable standard tower crane section that is easy to transport and install. The folding design reduces the transport volume, makes it lightweight, quick to install, and structurally stable.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a detachable tower crane standard section that is easy to transport and install, comprising four parallel main rods, a first web member, a second web member, and a connecting plate; the four main rods are movably connected through the first web members to form a rectangular frame structure, wherein each first web member is connected between the tops of two adjacent main rods; each first web member and the two main rods it is connected to form a plane, and a connecting plate is provided in the middle of the plane; each connecting plate is movably connected to the ends of the corresponding two main rods by two second web members.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figures 1-5 As shown in the figure, this embodiment provides a detachable tower crane standard section that is easy to transport and install. It includes four parallel main rods 2, a first web member 1, a second web member 3, and a connecting plate 4. The four main rods 2 are movably connected by the first web members 1 to form a rectangular frame structure. Each first web member 1 is connected between the tops of two adjacent main rods 2. Each first web member 1 and the two main rods 2 it connects to form a plane, and a connecting plate 4 is located in the middle of this plane. Two second web members 3 are movably connected between each connecting plate 4 and the ends of the corresponding two main rods 2. Connecting lugs 5 are provided at both ends of the first web member 1 and the second web member 3. Connecting seats 6 are welded to the main rods 2 at the positions corresponding to the web members. Connecting holes 7 are opened on the connecting plate 4 at the positions corresponding to the connecting lugs 5. The connecting lugs 5 and the connecting seats 6 or the connecting holes 7 are detachably connected by high-strength bolts / pins. The connecting seat 6 is a plate welded and fixed to the main rod 2, and has mounting holes that match the connecting holes on the connecting lug plate 5. At least one of the main rods 2 is provided with a lifting hole 8, located on the rod body of the main rod 2, for positioning and bearing load during lifting and installation. The lifting hole 8 is located near the end of the main rod 2 to optimize the lever arm and balance during lifting. The main rod 2, the first web member 1, and the second web member 3 are all made of high-strength steel structure, and the connecting plate 4 is a reinforced steel plate, on which reinforcing ribs can be provided to improve local rigidity.

[0022] In this embodiment, a folding unit is formed by a first web member 1, two main members 2 connected to the first web member 1, a connecting plate 4 located in the plane of the two main members 2, and four second web members 3 connecting the connecting plate 4 to the ends of the two main members 2. The folding unit forms a scissor-shaped mechanism, which allows the two main members 2 to come closer together when a pressing force is applied toward the connecting plate 4, thereby realizing the folding of the standard section. In the scissor-shaped mechanism, the second web members 3 are connected to the connecting plate 4 and the connecting seats 6 at the ends of the main members 2 by hinge, so that the second web members 3 can rotate relative to the connecting plate 4 and the main members 2, thereby realizing the folding and unfolding actions.

[0023] The detachable tower crane standard section described in this utility model has a core working principle based on its unique scissor-shaped folding mechanism.

[0024] During transport and storage, the standard section needs to be folded. The operator simply needs to remove or loosen the high-strength bolts / pins connecting the connecting plate 4 and the second web member 3 in each folding unit. Then, the two opposing main members 2 are pressed towards the center of the standard section (i.e., towards the connecting plate 4). At this point, under the action of the scissor mechanism, the second web member 3, hinged to the connecting plate 4, will begin to rotate, pushing the main members 2 inward along the connection point of the first web member 1. After this operation is performed simultaneously on all four sides, the entire rectangular frame structure of the standard section will shrink horizontally, significantly reducing its volume, thus meeting the width and height restrictions for transport and saving storage space.

[0025] In the installation and use state, after the folded standard section is transported to the construction site, it is lifted by hooking the lifting hole 8 on the main rod 2 with hoisting equipment (such as an auxiliary hook). Under the action of gravity and slight external force, the folded main rod 2 will naturally droop and unfold in all directions. When the standard section is fully unfolded into the designed rectangular frame shape, the connecting holes of each component (connecting lug 5 and connecting seat 6, connecting lug 5 and connecting hole 7 on connecting plate 4) will be precisely aligned. At this time, inserting and tightening all high-strength bolts / pins will lock the entire structure into a stable and rigid cuboid frame. Multiple such standard sections are stacked and bolted together section by section through the connecting sleeves at the ends of their main rods 2 (not shown in the figure, but a standard design for tower crane standard sections), ultimately forming the main structure of the tower crane tower body.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
