Description

Technical Field

[0001] This invention relates to the field of offshore hoisting construction technology, and in particular to a hoisting construction device for integral steel reinforcement of cast-in-place offshore beams. Background Art

[0002] The construction of cast-in-place beam reinforcement at sea presents numerous unique challenges, especially as the complexity and uncertainty of the marine environment places higher demands on construction safety and efficiency. Traditional methods for constructing cast-in-place beam reinforcement at sea often rely on relatively simple hoisting equipment, which can meet construction needs when the wind and waves are small and the operating environment is relatively stable.

[0003] However, when encountering severe weather conditions, especially rough seas, traditional lifting equipment often struggles to guarantee the stability and safety of construction. For example, the offshore lifting devices proposed in Chinese Patent Publication No. 217126745 and Chinese Patent Publication No. 115744675 suffer from these problems. Specifically, in rough seas, the aforementioned offshore lifting equipment is prone to swaying or capsizing, leading to construction interruptions and even safety accidents. Furthermore, the offshore lifting equipment is relatively simple in structural design and function, lacking sufficient flexibility and adaptability, making it difficult to meet the complex and ever-changing needs of offshore construction. For instance, in extreme weather such as storms, traditional lifting equipment often cannot quickly adjust its status to cope with the harsh environment, resulting in equipment damage or injuries to construction personnel.

[0004] To address these issues, the industry urgently needs a new type of offshore cast-in-place beam reinforcement hoisting construction device that can adapt to the complex marine environment and improve construction stability and safety. This device has stronger wind and wave resistance, a higher level of automation, and a more flexible structural design, which can significantly improve the safety and efficiency of offshore cast-in-place beam reinforcement construction, providing more reliable protection for the construction of large structures such as offshore bridges, and meeting various challenges in offshore construction. Summary of the Invention

[0005] This invention provides a construction device for the integral hoisting of reinforcing steel bars in cast-in-place marine beams, comprising:

[0006] A mobile base and a folding hanging basket mounted on the mobile base, wherein the mobile base is equipped with a moving device, and the folding hanging basket includes a receiving chassis mounted on the mobile base and a hanging basket frame that is folded relative to the receiving chassis by a rotatable connection.

[0007] The hanging basket frame includes a central support column that is rotatably connected to accommodate the chassis.

The movable base 1000 is provided with a moving device 1100, and the folding hanging basket 2000 includes a receiving chassis 2100 disposed on the movable base 1000 and a hanging basket frame 2200 that is folded relative to the receiving chassis 2100 by a rotatable connection.

[0031] The hanging basket frame 2200 includes a central support column 2210 that is rotatably connected to accommodate a chassis 2100. A first connecting rod 2220 is fixedly connected to the upper end of the central support column 2210. A bottom connecting rod 2230 and an extension rod 2240 are rotatably connected to the first connecting rod 2220. The bottom connecting rod 2230 is slidably connected to accommodate the chassis 2100. A second connecting rod 2250 is provided at the end of the extension rod 2240 away from the first connecting rod 2220. The second connecting rod 2250 is rotatably connected to an extension rod 2260. The bottom end of the extension rod 2260 is slidably connected to accommodate the chassis 2100. The chassis 2100, the central support column 2210, and the bottom connecting rod 2230 form an approximately triangular structure. The central support column 2210, the extension rod 2240, and the extension rod 2260 also form an approximately triangular structure.

[0032] Anchoring device 3000 includes anchoring device 3100 and clamping device 3200. Anchoring device 3100 is located at one end of movable base 1000 away from hanging basket frame 2200, and clamping device 3200 is located on both sides of movable base 1000.

[0033] Specifically, the mobile base 1000 is welded from high-strength steel and is equipped with a mobile device 1100 at the bottom. The mobile device 1100 is designed with a tracked or hovercraft structure suitable for offshore operations to adapt to complex offshore terrain and ensure that the device can move smoothly and quickly to the designated location.

[0034] The mobile base 1000 includes a power system equipped with a high-power diesel engine or electric motor as the power source, which drives the tracked vehicle or hovercraft to move forward, backward, and turn through the transmission system. The mobile base 1000 also includes a navigation and positioning system integrating GPS navigation, radar, and sonar sensors to achieve precise navigation and positioning, ensuring that the device can accurately reach the construction location.

[0035] An anchoring device 3100 is installed at the end of the mobile base 1000 away from the hanging basket frame 2200. The device is fixed by anchor chains or anchor piles driven into the seabed to prevent drifting during hoisting.

[0036] Specifically, the housing chassis 2100, which serves as the supporting foundation for the hanging basket frame 2200, is made of high-strength materials to ensure that it can withstand enormous pressure without deformation during hoisting. The hanging basket frame 2200 is folded relative to the housing chassis 2100 via a rotatable connection, which facilitates reducing its volume during transportation and storage.

[0037] The hanging basket frame 2200 includes components such as a central support column 2210, a first connecting rod 2220, a bottom connecting rod 2230, an extension rod 2240, a second connecting rod 2250, and a support rod 2260, forming a stable triangular structure to enhance the load-bearing capacity and anti-overturning ability of the hanging basket.

[0038] Furthermore, a central support groove 2110, a bottom connection groove 2130, and an extension groove 2150 are provided in the chassis 2100 to accommodate the central support column 2210, the bottom connection rod 2230, and the extension rod 2260, respectively. The rotation and sliding of these components are achieved by a rotation drive device 2120, a sliding drive device 2140, and a sliding drive device 2160, so as to adjust the shape and height of the hanging basket to adapt to different hoisting requirements.

[0039] Furthermore, the central support column 2210 is connected to the central support groove 2110 of the housing chassis 2100 via precision bearings and a rotating device, enabling 360-degree rotation and a certain angle of tilt. The first connecting rod 2220 is fixedly connected to the upper end of the central support column 2210, serving as a support point for the bottom connecting rod 2230 and the extension rod 2240. The bottom connecting rod 2230 is connected to the bottom connecting groove 2130 of the housing chassis 2100 via a sliding connection, allowing its position and angle to be adjusted as needed. Under the action of the second connecting rod 2250, the extension rod 2240 can further extend the span of the hanging basket, adapting to the hoisting requirements of steel bars of different sizes. The second connecting rod 2250 and the extension rod 2260 form a stable triangular structure, enhancing the hanging basket's anti-overturning ability.

[0040] like Figures 1 to 3 As shown, in this embodiment, the clamping device 3200 includes retractable extension arms 3210 respectively disposed at both ends of the movable base 1000.

The rotation drive device 2120 adopts a hydraulic or electric drive method, and realizes the rotation of the central support column 2210 through gear transmission or chain transmission to ensure smooth and reliable rotation.

[0042] like Figures 1 to 4As shown, in this embodiment, a bottom receiving groove 2130 is provided in the receiving chassis 2100 to accommodate at least part of the bottom receiving rod 2230. The bottom end of the bottom receiving rod 2230 is slidably rotatably connected to the bottom receiving groove 2130. A sliding drive device 2140 for driving the bottom receiving rod 2230 to move is provided in the bottom receiving groove 2130. The sliding drive device 2140 adopts a combination of a high-precision threaded drive rod 2143 and a sliding drive motor, and achieves precise sliding of the bottom receiving rod 2230 through threaded transmission.

[0043] like Figure 4 As shown, in this embodiment, the sliding drive device 2140 includes a bottom connecting slider 2141 rotatably connected to the bottom end of the bottom connecting rod 2230, a bottom connecting groove 2142 disposed in the bottom connecting groove 2130 to accommodate the sliding of the bottom connecting slider 2141, and a threaded drive rod 2143 threadedly connected to the bottom connecting slider 2141 sliding relative to the bottom connecting groove 2142. The threaded drive rod 2143 is connected to a sliding drive motor.

[0044] like Figures 1 to 3 and Figure 5 As shown, in this embodiment, an extension groove 2150 is provided in the housing chassis 2100 to accommodate at least a portion of the extension rod 2260. The bottom end of the extension rod 2260 is slidably rotatably connected to the extension groove 2150. A sliding drive device 2160 for driving the extension rod 2260 to move is provided in the extension groove 2150. The sliding drive device 2160 adopts a combination of a high-precision sliding drive rod 2163 and a sliding drive motor, and achieves precise sliding of the extension rod 2260 through threaded transmission.

[0045] like Figure 5 As shown, in this embodiment, the sliding drive device 2160 includes an extension slider 2161 rotatably connected to the bottom end of the extension rod 2260, an extension groove 2162 disposed in the extension groove 2150 to accommodate the sliding of the extension slider 2161, and a sliding drive rod 2163 threadedly connected to the extension slider 2161 sliding relative to the extension groove 2162. The sliding drive rod 2163 is threadedly connected to the extension slider 2161, and the sliding drive rod 2163 is connected to a sliding drive motor.

[0046] like Figures 1 to 5 As shown, in this embodiment, a limiting protrusion 2241 is provided above the extension rod 2240 away from the first connecting rod 2220 for fixing the crossbar used for suspension. Furthermore, a stop edge 2170 is provided at the end of the housing 2100 away from the anchoring device 3100.

[0047] In some embodiments, the entire device's control system is integrated into a central control unit, enabling remote control and automated operation through remote control or automatic driving technology. Furthermore, sensors are installed at key locations to monitor the device's status and parameters in real time, such as weight, tilt angle, and stress distribution, ensuring safety and stability during operation. Simultaneously, an emergency braking system is provided; upon detecting an abnormality or receiving an emergency braking command, all drive mechanisms are immediately stopped.

[0048] The present invention, through the clamping devices set on both sides of the mobile base, can effectively increase the stability of the entire hoisting construction device when operating at sea. Especially in the case of large winds and waves, the clamping arms and clamping parts of the clamping devices can firmly clamp the surrounding structure, preventing the device from overturning due to wind and waves, thereby ensuring the safe progress of construction.

[0049] The design of the folding hanging basket allows the device to be folded up when not in use, greatly reducing the space occupied and facilitating transportation and storage. At the same time, in case of emergencies such as storms, if there is no time to evacuate from the bridge deck, the hanging basket frame can be quickly folded up to reduce the impact and damage of wind and rain on the device, thereby improving the durability and service life of the device.

[0050] The rotating drive device, sliding drive device, and gliding drive device, driven by motors, enable the automated unfolding and folding of the hanging basket frame, as well as the sliding adjustment of the bottom connecting rod and extension rod, improving construction efficiency and reducing the labor intensity of workers. The design of the hanging basket frame adopts multiple triangular structures, which are mechanically very stable and can withstand large loads, while ensuring the stability and safety of the device.

[0051] This invention has many applications, including but not limited to the following described scenarios:

[0052] In offshore bridge construction, especially in areas with large waves, this device can significantly improve construction safety and efficiency. It is also suitable for large-scale offshore structure construction, such as offshore platforms and offshore wind power facilities, which require cast-in-place reinforced concrete beams. In projects requiring rapid deployment and evacuation, its foldable structure facilitates quick deployment and evacuation, making it ideal for projects demanding rapid response and flexible adjustments to construction plans. Furthermore, in the event of severe weather such as storms, the device can be quickly folded and retracted, minimizing the impact of weather on construction and ensuring the safety of personnel and the integrity of equipment.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
