Description

Technical Field

[0001] The 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] In modern building and infrastructure construction, pile foundation is a common foundation treatment method, especially in the construction of high-rise buildings, bridges and other heavy structures. As an important part of the pile foundation, the accuracy of the lowering of the steel cage directly affects the quality of the pile and the safety of the entire project. The traditional method of lowering the steel cage usually relies on manual operation and simple mechanical assistance, which is not only inefficient but also difficult to ensure the precise positioning of the steel cage. With the development of construction technology and the improvement of project quality requirements, it is particularly important to develop an efficient, accurate and safe steel cage positioning and lowering device.

[0003] In the prior art, the lowering of the steel cage mainly has the following problems: First, the traditional method often relies on visual inspection or simple measuring tools to determine the position of the steel cage, which is easily affected by human factors and leads to 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 laborious, 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, improper operation 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.

Then, the auxiliary transportation platform 500 is horizontally moved to the vicinity of the lowering docking platform 200 through the moving unit 530 and the moving adjustment component 400. When the auxiliary transportation platform 500 is close to the lowering docking platform 200, the movable sliding component 540 starts to work and adjusts the height of the transportation platform 520 to make it consistent with the height of the lowering docking platform 200. At this time, the docking component 550 plays a role, and the steel cage is accurately positioned in the docking groove 240 of the lowering docking platform 200 through the docking frame 552 and the docking telescopic rod 553. Once the steel cage is accurately positioned, the stable docking component 560 is started to firmly connect the transportation platform with the lowering docking platform. Finally, the steel cage is steadily lowered into the pile foundation hole through the semicircular frame 210 of the lowering docking platform 200 and the lowering platform 220. During the entire process, various components cooperate with each other to ensure the safety and positioning accuracy of the steel cage.

[0083] Further, 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 arranged on the linear drive seat 601, a linear drive member cooperating with the linear drive base 603 is arranged in the linear drive slot 602, a hydraulic telescopic rod 604 is arranged on the linear drive base 603, and a semicircular arc frame 605 cooperating with the semicircular frame 210 is arranged 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, a support plate 607 is arranged in the bracket 606, a telescopic rod 608 cooperating with the support plate 607 is arranged on the semicircular arc frame 605, a plurality of extruded telescopic rods 609 are arranged on the semicircular arc frame 605, and a fitting arc plate 610 cooperating with the steel cage is arranged at the movable end of the extruded telescopic rod 609.

[0085] Specifically, the core function of the position adjustment component 600 is to accurately control the position of the steel cage in three-dimensional space to ensure that it can be accurately aligned with the pile hole and smoothly lowered. It not only needs to be able to move and adjust in the horizontal direction, but also needs to be able to fine-tune in the vertical direction and angle to adapt to steel cages and pile holes of different shapes and sizes. Among them, the linear drive seat 601 provides a stable base with a linear drive slot 602 on it. This slot allows the linear drive base 603 to translate along a predetermined path. Through linear drive parts such as electric push rods, lead screws, etc., the movement of the linear drive base 603 along the linear drive slot 602 can be accurately controlled, thereby achieving fine adjustment of the steel cage in the horizontal direction. The hydraulic telescopic rod 604 is connected to the linear drive base 603 and can be extended or shortened as needed, which enables the position adjustment component 600 to be adjusted in the vertical direction. The hydraulic system provides a strong force output, which is enough to support heavy steel cages, and the speed can be adjusted through the flow control valve to ensure smooth movement.

[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 the bottom end thereof for placing the steel cage. The semi-circular frame 605 is provided with an extrusion telescopic rod 609, and the movable end of these telescopic rods 608 is equipped with a fitting arc plate 610, 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 clamps 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 unnecessarily due to the change of 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, the lowering platform 220 is provided with a storage groove 711 that cooperates with the lifting platform 710, the lifting platform 710 is provided with a lifting frame 720, the lifting frame 720 is provided with a lifting bracket 730 that slides with the lifting frame 720, the lifting frame 720 is provided with a lifting component 740 that cooperates with the lifting bracket 730, and the lifting bracket 730 is provided with an auxiliary lifting component 750 for assisting in lifting the lowering of the steel cage.

[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 lifting clamps 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 in cooperation with the lifting tripod, 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] Among them, the lifting platform 710 provides a basic support surface, which is usually installed on both sides of the transport platform 520 and can be stored in the storage groove 711 on the lowering docking platform 200 to save space and protect the equipment. The lifting frame 720 is installed on the lifting platform 710. They can be adjusted in height through the lifting component 740, such as a hydraulic cylinder, an electric push rod, etc., to adapt to different sizes of steel cages and different lowering requirements. By accurately controlling the movement of the lifting component 740, the operator can gradually release the steel cage while maintaining sufficient support force to ensure a smooth lowering process.

[0093] The lifting clamps 770 are mounted on the lifting cross frame 760 to directly contact and clamp the edges of the steel cage. These clamps are designed to fit the shape of the steel cage closely to provide a firm grip. The central control unit 780 allows the two lifting clamps 770 to move synchronously or adjust independently, such as a worm gear combination or a drive gear and rack system, which helps to more flexibly deal with steel cages of different shapes and sizes. Through the operation of the central control unit 780, the lifting clamps 770 can be moved in the same direction or in opposite directions to ensure that the steel cage is firmly fixed and also facilitate quick release.
