Description
Technical Field
[0001] This invention relates to the field of pile foundation engineering technology, specifically to a rebar cage anti-deformation device for pile foundation engineering that is easy to disassemble. Background Technology
[0002] In pile foundation construction, the steel cage serves as the skeleton of the concrete structure, and its structural stability directly affects the bearing capacity and safety of the pile foundation. However, the steel cage is usually welded together from multiple main bars and stirrups, and is in the shape of a hollow cylinder with limited rigidity. During transportation, hoisting, or long-term storage, it is prone to bending, twisting, and other deformations due to external forces (such as self-weight, collision, and compression), which makes it difficult to match with the pile hole and may even require reprocessing, seriously affecting construction efficiency and project quality.
[0003] However, most existing anti-deformation devices for steel cages use welding or fixed connections, which are time-consuming and labor-intensive to install and dismantle, and are not convenient for reuse and transportation. Secondly, supports are generally set at both ends of the steel cage, while the middle part lacks effective support, and the middle section of long steel cages is still prone to deformation.
[0004] Therefore, the present invention provides a steel cage anti-deformation device for pile foundation engineering that is easy to disassemble. Summary of the Invention

[0009] Multiple internal bracing anti-deformation components are evenly distributed between the cage head fixing components and the cage tail fixing components to support the inside of the steel cage and prevent deformation.
[0010] The cage head fixing component and the cage tail fixing component are connected by a central linkage shaft, and the multiple inner support anti-deformation components are connected to each other and to the cage head fixing component and the cage tail fixing component through a fixing mechanism.
[0011] As a further technical solution of the present invention, the breech fixing assembly includes a fixing plate and a drive motor mounted on the upper middle part of the fixing plate via a bracket. One end of the central linkage shaft passes through the fixing plate and is fixed to the output end of the drive motor. A power control box is also provided on the upper end of the fixing plate, and the power control box contains a controller and a power storage power supply.
[0012] As a further technical solution of the present invention, the breech fixing assembly further includes a plurality of positioning holes arranged in a circular array on the outer wall of the fixing plate, each positioning hole is equipped with an extension rod, and each extension rod is provided with a cross fastener;
[0013] One end of the extension rod is provided with a threaded rod corresponding to the positioning hole, and one end of the extension rod is screwed into the positioning hole through the threaded rod. The other end of the extension rod is fixed to the main steel bar on the steel cage through a cross fastener.
[0014] As a further technical solution of the present invention, the fixing mechanism includes a plurality of static sleeves provided at one end of each of the inner support anti-deformation components, and a set of connecting seats is provided on the outer surface of one end of each static sleeve. Each set of connecting seats consists of three and is fixed in a circular shape on the outer surface of one end.
[0015] Each pair of stationary sleeves is fixed together by a connecting seat and a connecting positioning rod.
[0016] As a further technical solution of the present invention, the cage tail fixing assembly includes a second fixing plate and a plurality of electric push rods arranged in a circular array on the upper end of the second fixing plate, and each electric push rod has a clamping block fixed to its telescopic end.
[0017] As a further technical solution of the present invention, the bottom middle part of the fixed disk one and the upper middle part of the fixed disk two are respectively fixed to one end of one of the stationary sleeves, and the central linkage shaft passes through multiple stationary sleeves and is rotatably connected to them.
[0018] As a further technical solution of the present invention, the inner support anti-deformation component includes three inner support plates arranged in an array, and each inner support plate has two inner support rods one and one inner support rod two hinged to one side.
[0019] It also includes a movable sleeve, the inner wall of which is machined with internal threads, and the surface of the central linkage shaft is machined with external threads corresponding to each of the movable sleeves to facilitate its linear movement. The movable sleeve and the central linkage shaft are connected by threads.
[0020] As a further technical solution of the present invention, the other ends of the two inner support rods on the inner support plate are hinged to the outer surface of the moving sleeve, and the other end of the inner support rod on the inner support plate is hinged to the outer surface of the stationary sleeve.

[0021] This invention provides an easily disassembled steel cage anti-deformation device for pile foundation engineering, which has the following advantages compared with the prior art:
[0022] 1. An easily disassembled anti-deformation device for steel cages used in pile foundation engineering. The extension rod of the cage head fixing component can be disassembled and replaced through the positioning hole to adapt to steel cages with different inner diameters. Moreover, the extension rod and the positioning hole are detachably connected by a threaded rod. The cross fastener is detachably fixed to the main reinforcement of the steel cage, which can improve its replaceability and applicability. The electric push rod and the clamping block of the cage tail fixing component can be adjusted by telescopic adjustment to clamp the end position of the steel cage. The electric push rod is synchronously controlled by the controller, which can flexibly adjust the support force of the cage tail to avoid damage to the steel cage due to excessive tightness or deformation due to excessive looseness. The cage head and cage tail fixing components are used to fix the two ends of the steel cage respectively, and multiple internal support anti-deformation components are evenly distributed in the middle section to achieve support for the entire length of the steel cage.
[0023] 2. An easily disassembled anti-deformation device for steel cages used in pile foundation engineering. The addition of multiple internal support anti-deformation components utilizes a movable sleeve to drive the internal support plates through threaded transmission, adapting to steel cages of different diameters. This eliminates the need for separate equipment for different specifications of steel cages. Furthermore, the three internal support plates of each internal support anti-deformation component are arranged in a circular array. Combined with the synergistic effect of internal support rod one and internal support rod two, they can evenly support the inner wall of the steel cage, effectively preventing bending and torsional deformation. Secondly, the drive motor rotates the central linkage shaft, precisely controlling the movement distance of the movable sleeve and thus adjusting the supporting force of the internal support plates. This effectively prevents deformation of the steel cage during transportation, hoisting, and storage, and adapts to different specifications of steel cages, significantly improving construction efficiency and project quality.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0040] Please see Figure 1-2This invention provides a technical solution for an easily disassembled anti-deformation device for steel cages used in pile foundation engineering: An easily disassembled anti-deformation device for steel cages used in pile foundation engineering includes a steel cage 1, the ends of which can be welded with lifting rings for easy hoisting and construction. It also includes a cage head fixing component 2, which is fixed to one end of the steel cage 1 for supporting and fixing one end of the steel cage 1. The cage head fixing component 2 includes a fixing plate 21 and a drive motor 22 mounted on the upper middle part of the fixing plate 21 via a bracket. One end of the central linkage shaft 6 passes through the fixing plate 21 and is fixed to the output end of the drive motor 22. A power control box 23 is also provided on the upper end of the fixing plate 21. The power control box 23 contains a controller and a storage power supply. The controller can be a PLC controller. The storage power supply powers the entire device and is detachable for easy replacement or charging.
[0041] like Figure 3 , 5 As shown in Figure 6, the cage head fixing assembly 2 also includes a plurality of positioning holes 24 arranged in a circular array on the outer wall of the fixing plate 21. Each positioning hole 24 is equipped with an extension rod 25, and each extension rod 25 is provided with a cross fastener 26. The size of the extension rod 25 can be arbitrarily selected according to the different inner diameters of the steel cage 1. The inner diameter of one of the buckles on the cross fastener 26 is adapted to the size of the main reinforcement of the steel cage 1, which facilitates fixing the extension rod 25 to the main reinforcement of the steel cage 1.
[0042] like Figure 6 As shown, one end of the extension rod 25 is provided with a threaded rod corresponding to the positioning hole 24, and one end of the extension rod 25 is screwed into the positioning hole 24 through the threaded rod. The other end of the extension rod 25 is fixed to the main steel bar on the steel cage 1 through the cross fastener 26. The purpose of using the detachable design of the positioning hole 24 and the extension rod 25 is to facilitate the selection of an appropriate length of extension rod 25 according to the different sizes of the steel cage 1.
[0043] like Figure 4 , 7 As shown in the figure, it also includes a cage tail fixing assembly 3, which is fixed at the other end of the steel cage 1 and is used to support and fix the other end of the steel cage 1. The cage tail fixing assembly 3 includes a fixing plate 31 and multiple electric push rods 32 arranged in a circular array on the upper end of the fixing plate 31. Each electric push rod 32 has a clamping block 33 fixed at its telescopic end. In use, the controller controls the multiple electric push rods 32 to extend synchronously, thereby pushing the clamping block 33 onto the main reinforcement of the steel cage 1 to achieve internal support of the other end of the steel cage 1. It can also further fix the central linkage shaft rod 6. When the electric push rod 32 retracts, the internal support of the steel cage 1 can be released.
[0044] like Figure 2 and 9As shown in Figure 10, it also includes multiple internal support anti-deformation components 4, which are equally spaced between the cage head fixing component 2 and the cage tail fixing component 3, for supporting the inside of the steel cage 1 to prevent deformation. The internal support anti-deformation component 4 includes three internal support plates 41 arranged in an array. Each internal support plate 41 has two internal support rods 42 and one internal support rod 43 hinged to one side.
[0045] like Figure 9 As shown, it also includes a movable sleeve 44, the inner wall of which is machined with internal threads. The surface of the central linkage shaft 6 is machined with external threads corresponding to each movable sleeve 44 to facilitate its linear movement. The movable sleeve 44 and the central linkage shaft 6 are threadedly connected. The other ends of the two inner support rods 42 on the inner support plate 41 are hinged to the outer surface of the movable sleeve 44, and the other end of the inner support rod 43 on the inner support plate 41 is hinged to the outer surface of the stationary sleeve 5. The three inner support plates 41 are arranged in a circular array. When the drive motor 22 drives the central linkage shaft 6 to rotate in the forward direction, multiple movable sleeves 44 will synchronously move along the central linkage shaft 6. The corresponding external thread moves linearly, thereby driving one end of multiple inner support rods 42 on its surface to move, adjusting the inner support rods 42 from an inclined state to a vertical state (i.e., increasing the angle between the inner support rods 42 and the moving sleeve 44). At the same time, since one end of the inner support rod 43 is hinged to the stationary sleeve 5, when one end of the inner support rod 42 is inclined, the angle between the inner support rod 43 and the stationary sleeve 5 will also increase. Thus, the inner support rods 42 and 43 will synchronously drive the inner support plate 41 to move closer to the inner wall of the steel cage 1, thereby supporting the inner wall of the steel cage 1 and facilitating deformation of the steel cage 1 during construction.
[0046] The cage head fixing component 2 and the cage tail fixing component 3 are connected by a central linkage shaft 6. The multiple internal support anti-deformation components 4 are connected to each other and to the cage head fixing component 2 and the cage tail fixing component 3 through a fixing mechanism. The fixing mechanism includes multiple stationary sleeves 5 set at one end of each internal support anti-deformation component 4. Each stationary sleeve 5 has a set of connecting seats 51 on the outer surface of one end. Each set of connecting seats 51 consists of three and is circularly fixed to the outer surface of one end. Every two stationary sleeves 5 are fixed together by connecting seats 51 and connecting positioning rods 52. The fixing mechanism can connect the multiple internal support anti-deformation components 4 to the central linkage shaft 6 to ensure that when the central linkage shaft 6 rotates, the multiple internal support anti-deformation components 4 can be expanded or contracted synchronously to support the inner wall of the steel cage 1.
[0047] The bottom middle of fixed plate 1 21 and the upper middle of fixed plate 2 31 are respectively fixed to one end of one of the stationary sleeves 5. The central linkage shaft 6 passes through multiple stationary sleeves 5 and is rotatably connected to them. It should be noted that the two outermost stationary sleeves 5 are respectively connected to the bottom middle of fixed plate 1 21 and the upper middle of fixed plate 2 31. The central linkage shaft 6 is rotatably mounted on the stationary sleeves 5.
[0048] In addition, it should be added that the central linkage shaft 6 can be spliced by using flanges and bolts. For example, flanges can be welded to the two ends of the central linkage shaft 6 and then fixed by bolts. The purpose is to be able to accommodate steel cages 1 of different lengths, so as to facilitate the addition of different numbers of internal bracing anti-deformation components 4.
[0049] The working principle of the present invention is as follows: When in use, select an extension rod 25 of appropriate length according to the inner diameter of the steel cage 1, screw the extension rod 25 into the positioning hole 24 of the fixing plate 21 through the threaded rod, and then fix the extension rod 25 to the main steel bar at one end of the steel cage 1 through the cross fastener 26 to complete the installation of the cage head fixing component 2.
[0050] Furthermore, the fixing plate 31 of the cage tail fixing assembly 3 is placed inside the other end of the steel cage 1. The electric push rod 32 is activated by the controller of the power control box 23, and multiple electric push rods 32 are controlled to extend synchronously, pushing the clamping block 33 to clamp the main steel bar at the other end of the steel cage 1, thereby achieving the internal support fixing of the cage tail end. At the same time, the fixing plate 31 is connected to the central linkage shaft 6 through the static sleeve 5, further fixing the position of the central linkage shaft 6.
[0051] Furthermore, multiple internal support anti-deformation components 4 are placed at equal intervals between the cage head fixing component 2 and the cage tail fixing component 3. The static sleeves 5 of adjacent internal support anti-deformation components 4 are connected and fixed through the connecting seat 51 and the connecting positioning rod 52. The fixing plate 21 of the cage head fixing component 2 and the fixing plate 31 of the cage tail fixing component 3 are fixed to the static sleeves 5 at both ends respectively. At this time, the central linkage shaft 6 passes through all the static sleeves 5 and the moving sleeves 44.
[0052] Then, start the drive motor 22, which drives the central linkage shaft 6 to rotate. Since the moving sleeve 44 is threadedly connected to the central linkage shaft 6, the rotation of the central linkage shaft 6 drives the moving sleeve 44 to move linearly along its axis. During the movement of the moving sleeve 44, the inner support plate 41 is pushed outward by the inner support rod 1 42, and the inner support rod 2 43 cooperates to support it, so that the three inner support plates 41 are simultaneously pressed against the inner wall of the steel cage 1, thereby achieving uniform support for the middle section of the steel cage 1.
[0053] After use, control the drive motor 22 to rotate in the reverse direction, which drives the central linkage shaft 6 to rotate in the reverse direction, causing the moving sleeve 44 to move in the reverse direction along the central linkage shaft 6. The inner support rod 1 42 and the inner support rod 2 43 drive the inner support plate 41 to retract, releasing the support on the inner wall of the steel cage 1.
[0054] Then, the controller controls the electric push rod 32 to retract, which drives the clamping block 33 to detach from the main bar of the steel cage 1, releases the inner support fixing at the tail end of the cage, and then removes the connecting positioning rod 52 on the connecting seat 51, separates each static sleeve 5, removes the inner support anti-deformation component 4, and finally, unties the cross fastener 26 from the main bar of the steel cage 1, and screws the extension rod 25 out of the positioning hole 24 to complete the disassembly of the cage head fixing component 2.
[0055] Through the above process, the present invention can achieve rapid installation and convenient disassembly of the steel cage 1, effectively prevent the steel cage 1 from deforming during transportation, hoisting and storage, and can adapt to steel cages 1 of different specifications, significantly improving construction efficiency and project quality.
