Description

Technical Field

[0001] This utility model belongs to the field of tower crane technology, specifically relating to an internal climbing and external roof combination tower crane. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] With the increasing number of large-scale infrastructure projects, such as ultra-high-rise wind turbine towers and long-span bridges, the demand for independent height of tower cranes (hereinafter referred to as "tower cranes") is rising. Traditional tower cranes rely on attachment devices to be fixed to the building structure to increase their height, but this has the following problems:

[0004] Dependence on attachment devices: Some building structures, such as wind turbine towers and bridge main towers, cannot install attachment devices due to design limitations, making it impossible for traditional tower cranes to meet the needs of ultra-high hoisting.

[0005] Inefficient tower heightening: Existing technologies increase the height by increasing the number of standard tower sections, but this requires frequent disassembly and reassembly of the attachment frame, resulting in a long installation cycle and high costs;

[0006] Transportation and assembly difficulties: The integral tower section is large in size, resulting in high transportation costs. On-site assembly requires the assistance of large cranes, which reduces flexibility.

[0007] Insufficient stability: The base support of ultra-high independent tower cranes is weak, making them susceptible to wind loads and overturning moments, resulting in significant safety hazards. Utility Model Content

Detailed Implementation

[0032] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] Example 1

[0034] In a typical embodiment of this utility model, such as Figure 1-7 As shown, an internal climbing and external top combined tower crane is provided, including a counterweight bottom beam 1, which is set on the foundation. A counterweight block 2 and a bottom section 4 are installed on the counterweight bottom beam 1. A support section 5 is provided on the bottom section 4. A diagonal brace 3 is provided between the outer periphery of the counterweight bottom beam 1 and the support section 5. A transition beam 6 is provided on the upper part of the support section 5. A first tower body section 7 is provided on the transition beam 6. A support beam 8 is detachably provided inside the first tower body section 7. A second tower body section 10 is installed on the support beam 8. An internal climbing system 9 is provided at the top of the first tower body section 7 and the outer periphery of the second tower body section 10. An outer frame 11 is provided on the outer periphery of the second tower body section 10. An upper structure part 12 is provided at the top of the second tower body section 10.

[0035] This utility model, through its split tower structure, modular counterweight system, and coordinated internal climbing and external jacking lifting technology, enables the tower to reach an ultra-high independent height without the need for attachment devices. The specific process of tower lifting includes:

[0036] First, during the initial installation phase, such as Figure 1 As shown, a suitable foundation is selected and constructed at the construction site to ensure that the ground bearing capacity meets the standards. A counterweight beam 1 is set on the foundation. The position is calibrated by a level. Multiple counterweight blocks 2 are set on the counterweight beam 1 according to the actual situation and dynamically adjusted to achieve tower stability.

[0037] Second, assemble the bottom structure of the tower body. Vertically install and fix the bottom section 4 on the counterweight bottom beam 1. Install the support section 5 on the top of the bottom section 4 and connect it to the first tower body section 7 by setting a transition beam 6 on the support section. Connect the lower end of the diagonal brace 3 to the counterweight bottom beam 1 with bolts, and the upper end of the diagonal brace 3 is hinged to the support section 5. Adjust the length and tilt angle of the diagonal brace 3 and apply prestress to enhance the overturning resistance of the bottom structure.

[0038] Third, increase the height of the second tower section by 10, such as Figure 2 As shown, a crane is used to hoist the second tower section 10 to the top of the support section 5 for temporary fixation. The outer frame 11 is suspended on the outside of the installed second tower section 10. The second tower section 10 to be added is hoisted into the outer frame 11. The outer frame 11 guides the vertical docking of the subsequent second tower sections 10, and the second tower section 10 is gradually increased to the initial design height.

[0039] Fourth, the first tower section 7 is installed around the outer perimeter of the second tower section 10, such as... Figure 3 As shown, the first tower section 7, composed of two C-shaped structures, is installed section by section on the periphery of the second tower section 10 using the tower crane's own hook. The support beam 8 runs horizontally through the interior of the first tower section 7, with its two ends fitting into the inner wall of the first tower section 7. The installation position of the support beam 8 is adjusted according to the tower height to ensure a rigid connection between the second tower section 10 and the first tower section 7.

[0040] Fifth, activate the hydraulic lifting cylinder of the internal climbing system 9, such as... Figure 4 As shown, the second tower section 10 and the upper structure 12 are lifted and fixed in place, enabling the tower crane to reach an ultra-high independent height without the need for attachment devices.

[0041] Furthermore, the counterweights 2 are symmetrically arranged on both sides of the bottom section 4, and there are multiple counterweights 2. The counterweights 2 can be dynamically adjusted according to the foundation and the lifting height to provide a certain degree of stability for the tower lifting process.

[0042] Furthermore, the lower end of the diagonal brace 3 is connected to the counterweight base beam 1 by bolts, and the upper end of the diagonal brace 3 is hinged to the support section 5. The diagonal brace 3 converts the overturning moment into axial pressure, thereby improving the uplift resistance of the tower foundation.

[0043] Furthermore, the diagonal bracing rods 3 are symmetrically arranged around the periphery of the support section 5, forming a triangular structure with the counterweight bottom beam 1, the support section 5, and the diagonal bracing rods 3. This triangular structure enhances the stability of the tower body during the segment-by-segment lifting process.

[0044] Furthermore, the vertical structural axis of the first tower section 7 coincides with the vertical structural axis of the second tower section 10. This reduces the bending moment of the tower structure and maintains its stability.

[0045] Furthermore, the first tower section 7 is configured as two symmetrical, split C-shaped structural components, which are joined together to form a closed cross-section around the second tower section 10. This configuration facilitates the transportation of the two symmetrical, split C-shaped structural components, which can then be assembled upon arrival. The split tower section reduces transportation costs, decreases the volume of individual components, is suitable for transportation on narrow roads, and improves on-site assembly efficiency.

[0046] Furthermore, the first tower section 7 and the second tower section 10 are arranged in a rectangular frame structure, with the transverse rectangular cross-section of the first tower section 7 being larger than that of the second tower section 10. This facilitates the first tower section 7 being positioned on the periphery of the second tower section 10 to achieve internal climbing and jacking.

[0047] Furthermore, the support beam 8 is horizontally and detachably installed inside the first tower section 7, and the second tower section 10 is vertically installed on the support beam 8. By setting the support beam 8 to extend horizontally through the interior of the first tower section 7, with its two ends engaging with the inner wall of the first tower section 7, the installation position of the support beam 8 can be adjusted according to the tower height, ensuring a rigid connection between the second tower section 10 and the first tower section 7, and enhancing the stability of the tower lifting process.

[0048] Furthermore, the internal climbing system 9 is equipped with hydraulic jacking cylinders, which are located at the top of the first tower section 7. The output end of the hydraulic jacking cylinders is connected to the periphery of the second tower section 10. In this embodiment, the number and location of the hydraulic jacking cylinders can be set according to the actual construction situation to achieve the jacking of the second tower section 10 and the upper structure 12 into position. By jacking the second tower section 10 and the upper structure 12 with hydraulic jacking cylinders and fixing them in place, the tower crane can achieve an ultra-high independent height without the need for attachment devices.

[0049] Furthermore, the counterweight beam 1 is provided with a slot structure, and the counterweight block 2 is disposed within the slot structure. This arrangement ensures the stability of the counterweight block 2 on the counterweight beam 1.

[0050] This invention utilizes a split tower structure, a modular counterweight system, and a coordinated internal climbing and external jacking lifting technology to achieve an ultra-high independent height without the need for attachment devices. The split tower sections reduce transportation costs and the volume of individual transported components, making them suitable for transporting on narrow roads and improving on-site assembly efficiency. Dynamic adjustment of bottom stability adapts to complex foundation conditions, while the combination of counterweight bottom beams and diagonal braces enhances the bottom's anti-overturning capacity. Standardized interface design enables rapid disassembly and reuse.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
