[0001] This invention belongs to the field of building engineering technology, specifically relating to a full-rotation tower concrete placing machine and its construction method. Background Technology

[0002] In the construction industry, concrete tower placing booms are key equipment for concrete pouring. Traditional models, which only have vertical rotation capabilities and small turning radii, have exposed many problems in complex projects such as high-rise buildings, bridges, and double-shell structures of nuclear reactor buildings. When pouring in areas with small turning radii, concrete is prone to segregation due to excessive falling height, affecting the molding quality. Furthermore, it is difficult to flexibly avoid obstacles on the construction site, leading to frequent construction interruptions and low efficiency. Developing new concrete tower placing booms that can rotate both vertically and horizontally has become an urgent problem to be solved in the industry. Summary of the Invention

[0005] Furthermore, the full-rotation tower concrete placing boom also includes a tower crane support system; the tower crane support system is located below the base and is used to support the lifting and lowering of the tower crane structural fixing system; the tower crane support system includes a load-bearing component, a support frame, a climbing frame, a lifting cylinder, and a disc spring box; the load-bearing component is connected to the building structure; the load-bearing component is equipped with a load-bearing component flipper and a load-bearing component claw shoe; the load-bearing component flipper is hinged to the load-bearing component; the support frame is equipped with a support frame claw shoe; the support frame claw shoe is hinged to the load-bearing component flipper... The climbing frame is hinged with climbing frame flip claws on both sides; the climbing frame flip claws cooperate with the load-bearing component claw shoes; the disc spring box is located on the top of the support frame, the support frame is provided with a cavity for the lifting cylinder to pass through, the lifting cylinder includes a telescopic rod and a cylinder body; the bottom of the telescopic rod is connected to the bottom of the climbing frame through a ball joint structure, the cylinder body is equipped with an upper flange and a lower flange, the upper flange abuts against the top surface of the disc spring box, and the lower flange abuts against the bottom end surface of the support frame to lift the support frame.

[0006] Furthermore, the tower crane support system also includes a standard section for a concrete placing boom; the bottom of the standard section is fixedly connected to the cylinder body of the lifting cylinder, and the standard section is supported below the base.

[0007] Furthermore, the full-rotation tower concrete placing boom also includes an integrated platform; the integrated platform is connected between the standard section of the concrete placing boom and the base.

[0008] Furthermore, the full-rotation tower concrete placing boom also includes a hanging frame, which is suspended below the integrated platform.

[0009] Furthermore, the building structure includes a double-shell structure for a nuclear reactor building, the double-shell structure including an inner shell and an outer shell; the outer shell is spaced apart on the outside of the inner shell; the hangers are suspended between the inner shell and the outer shell or on both sides of the outer shell; the tower crane support system is located on the outside of the outer shell.

This invention has high practical value and market prospects for promoting technological innovation in traditional construction machinery and equipment and improving the quality of concrete pouring. It provides an innovative solution for high-quality concrete pouring construction using tower concrete placing booms in the construction engineering field, offering significant economic and social benefits.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-10 The full-rotation tower concrete placing boom shown includes a tower crane structural fixing system, a tower crane rotation system, a concrete conveying system, a tower crane support system, a tower crane control system, an integrated platform, and a hanging frame.

[0028] The tower crane's structural fixing system includes a base 1, a tower body 2, a lower support 4, a jib 12, a forearm 5, and a counterweight 6.

[0029] The tower crane slewing system includes a vertical slewing assembly 9, a horizontal slewing assembly 10, and a hydraulic cylinder 11.

[0030] The concrete transport system includes a connected concrete pipe 3 and a concrete hose 13.

[0031] The tower crane support system includes load-bearing components 16, support frame 19, climbing frame 17, lifting cylinder 20, disc spring box 18, standard section of concrete placing boom 21, and reusable embedded parts 15.

[0032] The tower crane control system includes an electrical control system 7 and a hydraulic system 8, which are electrically connected.

[0033] The base 1, serving as the fundamental support component of the tower crane's structural fixing system, is secured to the foundation's embedded parts via anchor bolts, providing a stable load-bearing platform for the concrete placing boom. This effectively prevents the boom from tilting or overturning due to unstable foundations during operation, ensuring the equipment remains vertically stable under the loads of the superstructure and construction. In its connection with other components, the upper plane of the base 1 precisely aligns with the bottom of the tower body 2 and is fastened with high-strength bolts. It serves as the installation foundation for the superstructure, including the tower body 2, jib 5, and boom 12, bearing and transmitting all vertical and horizontal loads.

[0034] like Figure 2 As shown, the tower body 2 serves as a vertical support structure, bearing the weight of the upper boom (including the forearm 5 and the boom 12), concrete pipes, and concrete. Its internal space provides installation channels for cables, oil pipes, and concrete pipes, offering stable vertical support for the concrete placing boom and ensuring that the boom does not sway or shift during rotation and placement, greatly guaranteeing operational safety and accuracy. The bottom of the tower body 2 connects to the base 1, and the top connects to the lower support 4, forming a crucial link in force transmission. The pipes and cables arranged internally provide necessary channels for the electrical control system 7, the hydraulic system 8, and the concrete conveying system.

[0035] like Figure 2 As shown, the lower support 4 plays a crucial role in connecting the tower body 2 and the tower crane's slewing system. It provides an installation platform for the tower crane's slewing system and the jib 12, and serves as a support base for the vertical and horizontal rotation of the jib 12, responsible for transmitting the load between the tower body 2 and the jib. It achieves a reliable connection between the jib and the tower body 2, ensuring that the jib 12 can stably transmit torque during rotation and avoid deformation affecting the fabric placement accuracy. The bottom of the lower support 4 is connected to the top of the tower body 2, and the upper part is equipped with the vertical slewing assembly 9, the horizontal slewing assembly 10, and the jib 12. The vertical slewing assembly 9 and the horizontal slewing assembly 10 drive the jib 12 to rotate in coordination with the built-in slewing bearing and the hydraulic system 8.

[0036] like Figure 2 As shown, the tail of the forearm 5 is rigidly connected to the counterweight 6. The counterweight 6 installed at the tail forms a torque balance with the front load. The counterweight 6 effectively eliminates the risk of equipment tilting caused by uneven front load distribution, ensuring the safety and stability of the concrete placing boom during operation. The forearm 5 and the lowermost boom 12 are radially arranged along the transverse slewing assembly 10 on the lower support 4.

[0037] like Figure 2As shown, the boom 12 is the main concrete placing component, bearing the weight of the concrete pipe 3 and the concrete. It achieves vertical and horizontal rotation via the tower crane's slewing system, allowing concrete to be transported to areas inaccessible by traditional equipment, thus improving construction efficiency and pouring quality. The concrete pipe 3 is housed inside the boom 12. The boom 12 includes multiple booms arranged sequentially from bottom to top, connected to adjacent booms via a tower crane slewing system. The lowest boom is connected to the lower support 4 via another tower crane slewing system. One end of the hydraulic cylinder is hinged to the horizontal slewing assembly, and the other end is hinged to the boom connected to the vertical slewing assembly 9. The vertical slewing assembly drives the boom connected to it to rotate in the vertical plane, while the horizontal slewing assembly 10 drives the boom connected to it to rotate in the horizontal plane. The hydraulic cylinder 11 performs folding and extending movements and provides support. Both the vertical slewing assembly 9 and the horizontal slewing assembly 10 can utilize existing slewing assemblies.

[0038] like Figure 2 As shown, one end of the hydraulic cylinder 11 is hinged to the transverse slewing assembly 10, and the other end is hinged to the boom connected to the vertical slewing assembly 9. Hydraulic oil drives the piston rod of the cylinder 11 to extend and retract, thereby driving the boom 12 to perform extension and folding movements, enabling the boom 12 to flexibly retract and expand, adapting to different pouring distances and height requirements, and improving the adaptability of concrete placement operations. The hydraulic cylinder 11 is connected to the pump station and oil pipes of the hydraulic system 8, receiving hydraulic pressure for drive. Through the hinge point, it is mechanically connected to the boom 12, converting hydraulic energy into mechanical energy.

[0039] like Figure 2 As shown, the concrete pipeline 3 extends from the bottom of the tower body 2 to the end of the jib 12, serving as a concrete conveying channel. It plays a crucial role in transporting concrete from the pump truck to the pouring point, ensuring no leakage or blockage occurs during transport and guaranteeing the continuity and uniformity of the pouring. It is arranged along the tower body 2, lower support 4, and inside the jib 12, connecting to the concrete hose 13 and fixed to the jib structure with pipe clamps, moving synchronously with the jib's movement. The concrete pipeline 3 has a flexible bending section at the tower crane's slewing system. This flexible bending section can be made of a flexible and extendable corrugated hose to accommodate the bending between the different sections of the jib 12.

[0040] like Figure 2 As shown, the concrete hose 13 is connected to the end of the boom 12, serving as the terminal for concrete delivery. Its position can be flexibly adjusted with the movement of the boom 12, enabling precise concrete pouring and allowing concrete to be poured into complex shapes or narrow areas. One end is connected to the quick-connect coupling of the concrete pipe 3 at the end of the boom 12, while the other end directly contacts the pouring surface, allowing for multi-directional angle pouring.

[0041] like Figure 2As shown, during installation, anchor bolts for base 1 are pre-embedded to ensure the horizontality of the foundation plane and the precise positioning of the anchor bolts. Then, base 1 is hoisted to the foundation, fixed to the embedded parts with high-strength bolts, and its verticality is calibrated. Next, each section of tower body 2 is hoisted sequentially, and its verticality is checked after each section is connected. Afterwards, the lower support 4, vertical slewing assembly 9, horizontal slewing assembly 10, boom 12, jib 5, counterweight 6, electrical control system 7, hydraulic system 8, and cylinder 11 are assembled. Concrete pipes 3 are pre-installed inside boom 12. The entire assembly is then hoisted to the top of tower body 2 and fixed to the lower support 4. Finally, the cables for electrical control system 7 and the oil pipes for hydraulic system 8 are connected, and the concrete pipes 3 and connecting concrete hoses 13 are installed.

[0042] like Figure 5 As shown, the electrical control system 7 controls the hydraulic system 8, vertical slewing assembly 9, horizontal slewing assembly 10, oil cylinder 11 and other components through the control cabinet, receives operation instructions and transmits control signals to ensure that the equipment operates according to the preset program, greatly improving the accuracy and stability of the fabric laying operation.

[0043] like Figure 6 As shown, the hydraulic system 8 provides power to the hydraulic actuators such as the cylinders 11, vertical slewing assembly 9, and horizontal slewing assembly 10 of the tower crane's slewing system. It drives the boom to rotate, extend, and fold through the transmission and pressure changes of hydraulic oil. It provides stable and controllable power output, ensuring smooth and reliable boom operation and adapting to the material placement requirements under different working conditions. The pump station of the hydraulic system 8 is connected to the vertical slewing assembly 9, horizontal slewing assembly 10, cylinders 11, and other hydraulic actuators via oil pipes. It works in conjunction with the electrical control system 7, receiving control signals to adjust oil pressure and flow.

[0044] like Figure 2 , Figure 6 As shown, each vertical slewing assembly 9 is arranged at one end of each boom segment of the boom 12, providing vertical rotational support and power for that boom segment, enabling the boom segments of the boom 12 to rotate in the vertical plane, thereby expanding the coverage range in the height direction of concrete placement and allowing concrete to be delivered to different floors or height positions. The slewing bearing is driven to rotate by a hydraulic motor, which is linked with the electrical control system 7 and the hydraulic system 8.

[0045] like Figure 7 and Figure 8 As shown, the climbing frame 17 is constructed by welding a box-shaped steel structure and is supported on the load-bearing component 16. The climbing frame flip claws 22, which are hinged on both sides, fit closely with the load-bearing component claw shoes 25 to transmit force, providing a horizontal force base for the tower crane support system to lift, raise, and lower. This solves the problem of easy horizontal deviation during equipment lifting and lowering, and works in conjunction with the support frame 19 to form a three-dimensional force transmission system to ensure stable load transmission.

[0046] like Figure 7 and Figure 9 As shown, the load-bearing component 16 is made of high-strength structural steel and is rigidly connected to the reusable embedded component 15 by high-strength bolts. The load-bearing component flip claw 24 and load-bearing component claw shoe 25 on it are respectively in multi-faceted contact with the support frame claw shoe 23 and the climbing frame flip claw 22 to transmit force, so as to smoothly transfer the upper load to the reusable embedded component 15, playing a key role in load transfer.

[0047] like Figure 7 and Figure 10 As shown, the reusable embedded part 15 is prefabricated using high-strength alloy materials and is precisely embedded during the concrete wall pouring stage of the double-shell structure 27 of the nuclear reactor building. It is rigidly connected to the load-bearing part 16 through high-strength bolts, serving as the basic connection point between the tower crane support system and the double-shell structure 27 of the nuclear reactor building. This enables the initial transfer of equipment load to the double-shell structure 27 of the nuclear reactor building, providing a stable connection foundation for the entire tower crane support system.

[0048] like Figure 7 As shown, the disc spring box 18 is arranged on the top of the support frame 19 and has a built-in high-strength disc spring assembly. The upper flange structure of the lifting cylinder 20 rests on it. In actual operation, the elastic deformation of the disc spring realizes buffering and shock absorption and load adjustment, which solves the problem of damage to the support frame 19 by the instantaneous impact force when the cylinder extends and retracts, and realizes the smooth transition and transmission of force between the cylinder and the support frame.

[0049] like Figure 7 As shown, the support frame 19 is made of high-strength steel with a lattice structure. A disc spring box 18 is installed on the top, and a rectangular cavity is provided in the middle for the lifting cylinder 20 to pass through. The support frame claws 23 on both sides of the bottom are precisely fitted with the load-bearing flip claws 24. In implementation, it bears the vertical load of the upper platform and equipment. The lattice structure reduces its own weight and improves its resistance to deformation, and stably transfers the load to the load-bearing component 16.

[0050] like Figure 7 As shown, the lifting cylinder 20 is a high-pressure hydraulic cylinder with an alloy structural steel body. During implementation, it passes through the rectangular cavities of the disc spring box 18 and the support frame 19 in sequence. The lifting cylinder 20 includes a telescopic rod and a cylinder body. The bottom of the telescopic rod is connected to the bottom of the climbing frame 17 through a ball joint structure. An upper flange and a lower flange are installed on the cylinder body. The upper flange abuts against the top surface of the disc spring box 18, and the lower flange abuts against the bottom surface of the support frame 19 to lift the support frame. This solves the problem of low efficiency in adjusting the height of traditional equipment and is suitable for the height construction requirements of nuclear reactor buildings.

[0051] like Figure 7As shown, the standard section 21 of the concrete placing boom is made of high-strength steel with a box-shaped cross-section structure. During implementation, it is connected section by section with high-strength bolts as an extension of the tower body 2. The interior accommodates concrete pipes 3, hydraulic oil pipes and electrical control cables, which solves the problem of insufficient height of a single tower body. It provides vertical support and provides a regular layout channel for the pipelines of each system, ensuring the continuity of equipment functions.

[0052] like Figure 7 and Figure 8 As shown, the climbing frame flipping claw 22 is made of alloy structural steel and is hinged to both sides of the climbing frame 17. It can be flexibly flipped during the lifting and lowering of the equipment, and it can make multi-faceted contact with the load-bearing claw shoe 25 to transmit force. This solves the problem of poor contact between the climbing frame 17 and the load-bearing component 16, ensures the stable transmission of horizontal force under different working conditions, and ensures the force balance of the climbing frame.

[0053] like Figure 7 and Figure 9 As shown, the support frame claw shoe 23 is made of wear-resistant alloy material and fixed to both sides of the bottom of the support frame 19. During implementation, it fits precisely with the load-bearing flip claw 24 to transmit vertical loads under construction conditions. This solves the problem of easy wear at the contact parts leading to a decrease in force transmission efficiency, ensures reliable connection between the support frame 19 and the load-bearing component 16, and extends the service life of the components.

[0054] like Figure 7 and Figure 10 As shown, the load-bearing flipper 24 is made of high-strength alloy structural steel and is hinged to the inside of the load-bearing member 16. During implementation, it can be flipped to a horizontal state and fits against the support frame claw shoe 23 to form a multi-faceted load-bearing structure, which solves the problem of excessive local stress caused by vertical load concentration and smoothly transfers the load to the load-bearing member 16.

[0055] like Figure 7 and Figure 10 As shown, the load-bearing claw shoe 25 is made of wear-resistant alloy material and fixed to the outside of the load-bearing component 16. During implementation, it fits with the climbing frame flip claw 22 to transmit force, providing horizontal force support for the climbing frame 17 during equipment lifting and lowering operations. This solves the problem of unstable horizontal load transmission and ensures the horizontal stability of the climbing frame 17.

[0056] It should be noted that the load-bearing components, support frame, climbing frame, lifting cylinder, and disc spring box of the tower crane support system in this embodiment can all adopt existing technologies, such as the top formwork self-lifting support system and its climbing device disclosed in Chinese Patent No. CN219794602U, which is a support system and climbing device designed and developed by our company and can be directly used in this embodiment.

[0057] like Figure 7As shown, the double-shell structure 27 of the nuclear reactor building serves as the final load-bearing foundation of the support system. During implementation, the pre-embedded reusable embedded parts 15 receive the loads transmitted by each component of the support system, solving the problem of the lack of a final load-bearing body for the equipment load. The high strength characteristics of the structure ensure the overall stability of the equipment and the building during construction.

[0058] like Figure 1 As shown, the bracket 26 is a frame structure welded from steel profiles. During implementation, it is suspended below the integrated platform 14 and arranged on both sides of the outer shell of the double-shell structure 27 of the nuclear reactor building, forming a multi-layer semi-enclosed working surface. This solves the problem of insufficient operating platform when the inner and outer shells are constructed simultaneously, provides safe operating space for construction, and works with the integrated platform 14 to achieve simultaneous construction of the double-shell structure, thereby improving efficiency.

[0059] Based on the same inventive concept, this invention also proposes a construction method for a double-shell structure of a nuclear reactor building. The construction method utilizes the aforementioned rotary tower concrete placing boom. The method includes the following steps: installing the rotary tower concrete placing boom at a predetermined position on the double-shell structure of the nuclear reactor building; starting the electrical control system 7; comprehensively checking the operating status of each component; testing the rotational flexibility of the vertical slewing assembly 9 and the horizontal slewing assembly 10; and adjusting the extension and folding movements of the boom 12 driven by the hydraulic cylinder 11 to ensure stable pressure and smooth operation of the hydraulic system 8. After adjustment, connecting the concrete pump truck to the concrete pipeline 3 of the placing boom, and operating the equipment through the electrical control system 7, using the vertical slewing assembly 9 and the horizontal slewing assembly 10 to achieve vertical and horizontal rotation of the boom 12, and the hydraulic cylinder 11 to control the extension and retraction of the boom 12, moving the concrete hose 13 to the pouring point for operation, while simultaneously monitoring the equipment and concrete delivery status in real time. When encountering complex construction environments, the boom angle is adjusted collaboratively through the slewing assembly, and the boom is flexibly extended and retracted to bypass obstacles and accurately complete the pouring.

[0060] like Figure 3 , Figure 4 As shown, there are three fully rotary tower placing booms, which are evenly distributed around the circumference of the double-shell structure 27 of the nuclear reactor building. The integrated platform 14 is uniformly set as a continuous annular structure around the circumference of the double-shell structure 27 of the nuclear reactor building.

[0061] During the dismantling of the full-coverage tower concrete placing boom, after pouring the concrete, the concrete pipes 3 and 13 should be cleaned immediately. The electrical control system 7 and hydraulic system 8 should be shut down, and the power and oil lines should be disconnected. Then, following the reverse installation sequence, the concrete hoses 13 and 3 should be removed in sequence. The cables of the electrical control system 7 and the oil pipes of the hydraulic system 8 should be disconnected. With the help of hoisting equipment, the boom 5, boom 12, horizontal slewing assembly 10, vertical slewing assembly 9, electrical control system 7, hydraulic system 8, cylinder 11, and lower support 4 should be dismantled. Finally, each section of the tower body 2 should be dismantled, and then the base 1 should be removed. During dismantling, care should be taken to protect the surface of the components, and the components should be classified and stored for subsequent processing.

[0062] This invention, through an innovative integrated vertical and horizontal dual-rotation system, combined with an optimized boom structure and intelligent control system, achieves flexible concrete placement through vertical and horizontal spatial rotation. This avoids the segregation that occurs with traditional tower cranes due to excessive concrete pouring height at close-range rotation radii, thus improving concrete forming quality. Furthermore, the combination of horizontal and vertical rotation during placement allows for flexible obstacle avoidance, adapting to more complex site environments. This invention patent has high practical value and market prospects for promoting technological innovation in traditional construction machinery and equipment and improving the quality of concrete pouring. It provides an innovative solution for high-quality concrete pouring using tower concrete placing booms in the construction engineering field, offering significant economic and social benefits.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
