Description

Technical Field

[0001] The present invention relates to the technical field of lowering a steel cage, and in particular to a steel cage positioning and lowering device and a construction method thereof. Background Art

[0002] Pile foundations are a common ground treatment method in modern building and infrastructure construction, especially in the construction of high-rise buildings, bridges, and other heavy structures. As a crucial component of pile foundations, the precision with which the steel cage is lowered directly impacts the quality of the pile and the safety of the entire project. Traditional methods for lowering the steel cage typically rely on manual operation and simple mechanical assistance, which is not only inefficient but also difficult to ensure precise positioning of the cage. With the advancement of construction technology and increasing demands for project quality, the development of an efficient, accurate, and safe device for positioning and lowering the steel cage has become increasingly important.

[0003] In the existing technology, the lowering of steel cages mainly has the following problems: First, traditional methods often rely on visual inspection or simple measuring tools to determine the position of the steel cage. This method is easily affected by human factors, resulting in inaccurate positioning. Secondly, due to the large size and heavy weight of the steel cage, it is easy to tilt or shake without proper support equipment, affecting the stability and safety during the lowering process. Furthermore, manually adjusting the position of the steel cage is time-consuming and labor-intensive, especially in large projects where multiple steel cages need to be lowered frequently. This inefficient operation will greatly extend the construction period. At the same time, during the manual handling and adjustment process, if the operation is improper, it may cause personal injury or equipment damage, increasing the construction risk. In addition, the pile hole sizes and shapes of different engineering projects vary, and the existing simple equipment often cannot adapt well to these changes, limiting its scope of application.

[0082] During transport and docking, the auxiliary transport platform 500 first receives the rebar cage from the hoisting equipment and secures it using the lowering groove 511 and circular groove 521 on the transport platform 520. Next, the auxiliary transport platform 500 is horizontally moved to the vicinity of the lower docking platform 200 using the moving unit 530 and the movement adjustment assembly 400. When the auxiliary transport platform 500 approaches the lower docking platform 200, the movable sliding assembly 540 activates, adjusting the height of the transport platform 520 to the same level as the lower docking platform 200. At this point, the docking assembly 550 activates, precisely positioning the rebar cage in the docking groove 240 of the lower docking platform 200 using the docking frame 552 and the docking telescopic rod 553. Once the rebar cage is accurately positioned, the stabilizing docking assembly 560 activates, securely connecting the transport platform to the lower docking platform. Finally, the rebar cage is smoothly lowered into the pile foundation hole via the semicircular frame 210 of the lower docking platform 200 and the lower docking platform 220. Throughout the entire process, various components work together to ensure the safety and positioning accuracy of the steel cage.

[0083] Furthermore, the position adjustment assembly 600 includes a linear drive seat 601 horizontally arranged on the transport platform 520, the linear drive seat 601 is provided with a linear drive slot 602, a linear drive base 603 cooperating with the linear drive slot 602 is provided on the linear drive seat 601, a linear drive member cooperating with the linear drive base 603 is provided in the linear drive slot 602, a hydraulic telescopic rod 604 is provided on the linear drive base 603, and a semicircular arc frame 605 cooperating with the semicircular frame 210 is provided at the telescopic end of the hydraulic telescopic rod 604;

[0084] A bracket 606 is provided at the bottom end of the semicircular arc frame 605, and a support plate 607 is provided in the bracket 606. A telescopic rod 608 cooperating with the support plate 607 is provided on the semicircular arc frame 605. Several extruded telescopic rods 609 are provided on the semicircular arc frame 605, and the movable end of the extruded telescopic rod 609 is provided with a fitting arc plate 611 cooperating with the steel cage.

[0085] Specifically, the core function of the position adjustment assembly 600 is to precisely control the position of the rebar cage in three dimensions, ensuring accurate alignment with the pile hole and smooth lowering. It must be capable of not only horizontal movement and adjustment, but also vertical and angular fine-tuning to accommodate cages and pile holes of varying shapes and sizes. The linear drive base 601 provides a stable foundation, equipped with a linear drive slot 602. This slot allows the linear drive base 603 to translate along a predetermined path. Linear drive components, such as electric push rods and lead screws, precisely control the movement of the linear drive base 603 along the linear drive slot 602, enabling fine horizontal adjustment of the rebar cage. A hydraulic telescopic rod 604, connected to the linear drive base 603, can be extended or shortened as needed, enabling vertical adjustment of the position adjustment assembly 600. The hydraulic system provides powerful force output, sufficient to support heavy rebar cages, and a flow control valve allows for speed adjustment to ensure smooth operation.

[0086] At the same time, the semi-circular frame 605 is designed to match the outer contour of the steel cage, and a bracket 606 is provided at its bottom end for placing the steel cage. The semi-circular frame 605 is provided with an extruded telescopic rod 609. The movable end of these telescopic rods 608 is equipped with a fitting arc plate 611, which can be close to the surface of the steel cage during the adjustment process to prevent the steel cage from shifting or tilting during the adjustment process. By controlling the action of the hydraulic telescopic rod 604, the angle of the semi-circular frame 605 can be changed to better adapt to the opening direction of the pile hole. In addition, while the position is adjusted, the lifting clamp 770 in the auxiliary lifting mechanism 700 will cooperate with the action. They will provide additional support when the steel cage is adjusted to prevent the steel cage from swinging unnecessary due to changes in the center of gravity.

[0087] Furthermore, the auxiliary lifting mechanism 700 includes a lifting platform 710 symmetrically arranged on both sides of the transport platform 520, a storage groove 711 is provided on the lowering platform 220 and cooperates with the lifting platform 710, a lifting frame 720 is provided on the lifting platform 710, a lifting bracket 730 that slides with the lifting frame 720 is provided on the lifting frame 720, a lifting component 740 that cooperates with the lifting bracket 730 is provided on the lifting frame 720, and an auxiliary lifting component 750 is provided on the lifting bracket 730 for assisting in lifting the steel cage to be lowered.

[0088] The auxiliary lifting component 750 includes a lifting cross frame 760 arranged on the lifting bracket 730, and the lifting cross frame 760 is symmetrically provided with a lifting clamp 770. The lifting cross frame 760 is provided with a central control unit 780 for controlling the two lifting clamps 770 to move in the same direction or in opposite directions. A lifting rod that cooperates with the steel cage is provided between the two auxiliary lifting components 750, and one end of the lifting rod is fixedly connected to the lifting clamp 770.

[0089] The central control unit 780 can be set as a central control rod, and the lifting clamp 770 is provided with a turbine that cooperates with the central control rod, and the central control rod is provided with two worm sections with opposite threads that mesh with the turbine; at the same time, the central control unit 780 can also be set as a driving gear, and the lifting cross frame 760 is provided with a driving rack that cooperates with the driving gear, and the driving rack is fixedly connected to the lifting clamp 770.

[0090] Preferably, the transport platform 520 is provided with a lifting tripod that cooperates with the lifting platform 710, and the docking bracket 230 is provided with a lifting inclined groove that cooperates with the lifting tripod.

[0091] In summary, the main function of the auxiliary lifting mechanism 700 is to provide additional support during the lowering of the steel cage to ensure its smooth descent. It not only helps to disperse the weight of the steel cage and reduce the pressure on other components, but also prevents it from tilting or losing control during lowering by fixing and controlling the position of the steel cage.

[0092] The lifting platform 710 provides a basic support surface and is typically mounted on either side of the transfer platform 520. It can be stored in the storage recess 711 on the lowering docking platform 200 to save space and protect the equipment. The lifting frame 720 is mounted on the lifting platform 710 and can be adjusted in height using a lifting assembly 740, such as a hydraulic cylinder or electric push rod, to accommodate different sizes of rebar cages and different lowering requirements. By precisely controlling the movement of the lifting assembly 740, the operator can gradually release the rebar cage while maintaining sufficient support force, ensuring a smooth lowering process.

[0093] Mounted on the lifting crossbar 760, the lifting clamps 770 directly contact and clamp the edges of the rebar cage. These clamps are designed to closely conform to the cage's contours, providing a secure grip. A central control unit 780 allows for synchronized or independent adjustment of the two lifting clamps 770, such as a worm gear combination or a rack and pinion system. This provides greater flexibility for handling cages of varying shapes and sizes. The central control unit 780 allows the lifting clamps 770 to move in the same or opposite directions, ensuring a secure hold on the cage while also facilitating quick release.
