Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for transporting steel cages, and in particular to a device and its assembly method for preventing steel cages from deforming due to vibration during transport. Background Technology

[0002] In the field of construction engineering, steel cages are a key component of structures such as pile foundations. Their quality is directly related to the structural safety and stability of the entire project. Ensuring that the steel cages do not deform during the processing and transportation of steel cages is an important prerequisite for guaranteeing project quality.

[0003] Currently, during the processing of steel cages, design drawings usually take into account the deformation problems that may occur during transportation and use, and take corresponding preventive measures. A common practice is to weld stiffening hoops inside the steel cage to enhance the overall rigidity of the steel cage and resist external forces. At the same time, to further resist deformation during transportation, cross steel bars are welded to the stiffening hoops to form a more stable internal support structure.

[0004] Construction sites often have complex road conditions, and in many cases, the roads are relatively bumpy. In order to save transportation space and costs, steel cages are usually transported by stacking during the process of transporting them from the processing plant to the construction site. Under this transportation method, the steel cages not only have to bear their own weight, but also experience up-and-down and left-and-right swaying and impact forces due to the bumpy roads. Although the steel cages are equipped with stiffening hoops and cross steel bars inside, these support structures still cannot completely prevent the steel cages from deforming when faced with complex and varied transportation vibrations.

[0005] In addition, after the steel cage is transported to the construction site, the cross-shaped steel bars inside the cage need to be removed. Removing the cross-shaped steel bars is difficult and requires a lot of manpower and time, which reduces construction efficiency. On the other hand, the removal process inevitably wastes steel bars, increasing project costs. During the removal of the cross-shaped steel bars, due to the limited operating space and the difficulty in precisely controlling the force, there is a chance that the welded points of the main steel bars of the steel cage will be loosened, affecting the overall structural stability of the steel cage and reducing its load-bearing capacity. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a device and its assembly method for preventing deformation of steel cages during transportation due to vibration.

[0007] The technical solution of the present invention is achieved through the following scheme: a device for preventing deformation of steel cages during transportation due to vibration, comprising a steel cage, a shock-absorbing outer support and an adjustable inner support for energy dissipation, wherein the steel cage is reinforced with a stiffener and a plurality of adjustable inner supports for energy dissipation are abutted inward, and the plurality of steel cages are placed on a plurality of shock-absorbing outer supports. The shock-absorbing external support includes a hollow steel truss, an adjustment component, a first elastic shock absorber, and a second elastic shock absorber. The adjustment component is installed on the hollow steel truss. The first elastic shock absorber and the second elastic shock absorber are movably mounted on the adjustment component so that the first elastic shock absorber and the second elastic shock absorber can slide relative to each other on the hollow steel truss. Several of the reinforcing cages are placed on the first elastic shock absorber and the second elastic shock absorber.

[0008] The above technical solutions, by setting up shock-absorbing external supports and adjustable internal supports for energy dissipation, protect the reinforcing cage from both internal and external perspectives. This effectively buffers the vibrations and impacts generated during transportation. The two systems work together to comprehensively and from multiple angles reduce the likelihood of deformation of the reinforcing cage due to vibration during transport, ensuring the quality of the cage and thus guaranteeing the structural safety and stability of the entire project. Furthermore, the adjustable internal supports eliminate the need to weld cross-shaped reinforcing bars inside the cage, fundamentally avoiding the problem of wasted reinforcing bars, eliminating the need for subsequent cumbersome removal procedures, and reducing additional costs due to structural issues. The external cost is reduced, saving manpower and time costs. The adjustable internal support for energy dissipation is adjustable and can be adjusted according to different specifications and sizes of steel cages to ensure a tight fit with the inner wall of the steel cage stiffener. The elastic shock absorber can absorb and dissipate vibration energy through its own elastic deformation, reducing the direct impact of vibration on the steel cage. The hollow steel truss, as the main structure of the shock absorber external support, is lightweight while ensuring its strength and rigidity. It can withstand the weight of the steel cage and various external forces that may be generated during transportation, ensuring the structural integrity and transportability of the entire equipment during transportation.

[0009] Preferably, the first elastic damping frame and the second elastic damping frame have the same structure. The first elastic damping frame includes an inner arc channel steel, an outer arc channel steel, a rubber anti-vibration pad, and a channel steel support frame. The inner arc channel steel is fixedly installed on the channel steel support frame. The outer arc channel steel is installed on the inner arc channel steel through a number of anti-vibration spring columns. The outer support surface of the outer arc channel steel is covered with a rubber anti-vibration pad. The channel steel support frame is slidably installed on the hollow steel truss through an adjustment component.

[0010] Preferably, the adjustment assembly includes a handwheel, a bidirectional screw, and a limiting slide rail. The limiting slide rail is fixedly installed on the hollow steel truss, and the bidirectional screw is rotatably installed inside the limiting slide rail. One end of the bidirectional screw passes through the limiting slide rail and is connected to the handwheel. The first elastic damping frame and the second elastic damping frame are both slidably installed inside the limiting slide rail via the bidirectional screw.

[0011] Preferably, the adjustable inner support for energy dissipation includes a first adjustable energy dissipation rod, a second adjustable energy dissipation rod, and a third adjustable energy dissipation rod. The first, second, and third adjustable energy dissipation rods have the same structure. One end of the first, second, and third adjustable energy dissipation rods is connected to a fixed point. The first, second, and third adjustable energy dissipation rods are arranged in an inverted Y-shape, and the included angle between adjacent rods is 120 degrees.

[0012] Preferably, the first adjustable energy dissipation support rod includes a hollow support rod, a support rod, a spring box, and a support plate. One end of the hollow support rod is connected to a fixed point through the spring box, and the other end of the hollow support rod is movably mounted with a support rod through an adjusting bolt. The support plate is fixedly mounted on the support rod.

[0013] Preferably, the support plate is arc-shaped, and the support rod abuts against the reinforcing cage stiffener through the support plate.

[0014] An assembly method for a device to prevent deformation of steel cages during transportation due to vibration includes the following steps: Step A: Determine the number and spacing of shock-absorbing external supports placed on the transport vehicle based on the length and weight of the steel cage; Step B: Determine the number of adjustable internal supports for energy dissipation based on the stiffening hoops of the reinforcing cage; Step C: Adjust the adjustable internal bracing for energy dissipation to provide internal support for the steel cage; Step D: Adjust the external shock-absorbing support to support multiple steel cages; Step E: When unloading the steel cage, the shock absorber outer support can be hoisted and temporarily stored at the same time; Step F: Dismantle the adjustable internal bracing for energy dissipation inside the steel cage.

[0015] As a preferred option, the specific judgment steps in step A include: a1. Based on the steel cage drawings, obtain the length and total weight parameters of the steel cage to be transported; a2, based on the length and total weight parameters of the steel cage, and according to the preset digital model of the load-bearing and damping of the external damping support, calculate the minimum number of external damping supports required and the standard spacing between two adjacent external damping supports. a3. Based on the calculated quantity and standard spacing, mark the installation positions of each shock-absorbing external bracket on the floor of the transport vehicle.

[0016] Preferably, the specific installation steps in step C include: c1. Place the steel cage horizontally to make it easy to operate. c2, Press the hollow struts to retract some of them into the spring box, and place them one by one into the internal cavity of the steel cage. The spatial position of each support and energy dissipation adjustable inner strut is moved and adjusted manually. c3, tighten the adjusting bolts in sequence to extend the support rod outward for fine adjustment, until the three support plates of the adjustable inner support for energy dissipation are all firmly against the stiffening hoops of the steel cage, forming a radial support force on the inner wall of the steel cage.

[0017] Preferably, in step D, according to the actual outer diameter parameters of multiple reinforcing cages, the handwheel is turned to simultaneously adjust the radial extension and contraction of the first and second elastic shock absorbers on the hollow steel truss until the support surface contour formed by the top of the first and second elastic shock absorbers fits the outer wall contour of the multiple reinforcing cages, thereby providing stable support for the multiple reinforcing cages during transportation.

[0018] In summary, the present invention has the following beneficial effects: 1. This invention protects the steel cage from both internal and external aspects by setting up shock-absorbing external supports and adjustable internal supports for energy dissipation. This effectively buffers the vibration and impact generated during transportation. The two work together to reduce the probability of deformation of the steel cage due to vibration during transportation in all directions and from multiple angles, thus ensuring the quality of the steel cage and ensuring the structural safety and stability of the entire project.

[0019] 2. By using adjustable internal supports for energy dissipation, there is no need to weld cross-shaped reinforcing bars inside the steel cage, fundamentally avoiding the problem of steel waste, avoiding the tedious subsequent removal process, reducing additional costs caused by structural issues, and saving manpower and time costs. Furthermore, the adjustable internal supports for energy dissipation are adjustable and can be adjusted accordingly for steel cages of different specifications and sizes to ensure a tight fit against the inner wall of the steel cage stiffeners. The elastic damping frame can absorb and dissipate vibration energy through its own elastic deformation, reducing the direct impact of vibration on the steel cage. The hollow steel truss, as the main structure of the damping external support, is lightweight while ensuring its strength and rigidity, and can withstand the weight of the steel cage and various external forces that may be generated during transportation, ensuring the structural integrity and transportability of the entire equipment during transportation.

[0020] 3. The rubber shock-absorbing pads initially absorb and disperse vibration energy, acting as the first layer of buffer. The seismic spring columns further dissipate vibration energy through their own elastic deformation, achieving the second layer of buffer. This multi-level buffering mechanism can more effectively reduce the impact of vibration on the reinforcing cage, greatly improving the shock absorption effect and preventing the reinforcing cage from deforming due to vibration to the greatest extent. The outer arc channel steel has a larger and more uniform contact area with the reinforcing cage, which can more evenly distribute vibration energy to the entire shock-absorbing frame, avoiding local stress concentration that could lead to local deformation of the reinforcing cage, thus providing more comprehensive and stable shock absorption protection for the reinforcing cage.

[0021] 4. By driving the bidirectional screw with a handwheel, the positions of the first and second elastic shock absorbers can be easily adjusted to meet the support requirements of steel cages with different diameters.

[0022] 5. An inverted Y-shape with consistent angles provides stable support to the reinforcing cage stiffener from multiple directions. Three support rods share the force, effectively preventing deformation or displacement of the reinforcing cage due to excessive local stress. The spring box absorbs and dissipates vibration energy through the elastic deformation of the internal springs, playing a flexible damping role, reducing the direct impact of vibration on the reinforcing cage, and lowering the stress generated by vibration. Each support rod can disperse and attenuate vibration energy to a certain extent, further improving the damping effect. Fine adjustments can be made by adjusting bolts to ensure that the support plate can fit tightly against the inner wall of the reinforcing cage stiffener, providing precise support and energy dissipation protection.

[0025] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein. Therefore, the invention is not limited to the specific embodiments disclosed in the following specification. The invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: A device for preventing deformation of steel cages during transportation due to vibration, such as... Figures 1-8 As shown, it includes a steel cage 1, a shock-absorbing outer support 2, and an adjustable inner support 3 for energy dissipation. Several adjustable inner supports 3 are abutted inside the stiffening hoop of the steel cage 1. Several steel cages 1 are placed on several shock-absorbing outer supports 2. The number of both the shock-absorbing outer supports 2 and the adjustable inner supports 3 is adjusted based on the main body of the steel cage 1. The shock-absorbing outer supports 2 and the adjustable inner supports 3 work together to form an internal and external protection system for the steel cage 1 during transportation.

[0028] The vibration damping external support 2 includes a hollow steel truss 21, an adjustment component 22, a first elastic damping frame 23, and a second elastic damping frame 24. The adjustment component 22 is installed on the hollow steel truss 21. The first elastic damping frame 23 and the second elastic damping frame 24 are movably mounted on the adjustment component 22 to enable the first elastic damping frame 23 and the second elastic damping frame 24 to slide relative to each other on the hollow steel truss 21. Several reinforcing cages 1 are placed on the first elastic damping frame 23 and the second elastic damping frame 24. In order to reduce the weight of the support while ensuring its strength and rigidity, the base adopts a hollow steel truss 21, which facilitates hoisting and movement during the installation of the vibration damping external support 2 and the unloading of the reinforcing cages 1. The first elastic damping frame 23 and the second elastic damping frame 24 are independent entities that slide relative to each other on the adjustment component 22 to meet the support requirements of reinforcing cages 1 of different diameters.

[0029] The hollow steel truss 21 is welded from high-strength low-alloy structural steel Q355B. The main body is a spatial truss structure with a triangular cross section and is completely hollow inside. While ensuring extremely high bending and torsional stiffness, it minimizes its own weight and reduces transportation energy consumption. The web members form stable triangular units, which effectively resist the lateral overturning moment that may be generated during transportation.

[0030] The lower chord has pre-set standardized bolt holes for quick installation of the adjustment assembly 22 and other accessories. The upper chord of the truss is equipped with a mounting plate that directly bears the vertical load from the first elastic damping frame 23 and the second elastic damping frame 24. The adjustment assembly 22 is fixedly installed in the center of the mounting plate as the main load-bearing component to evenly distribute the load.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the first elastic damping frame 23 and the second elastic damping frame 24 have the same structure. The first elastic damping frame 23 and the second elastic damping frame 24 are mirror symmetrical. The main support surfaces of the first elastic damping frame 23 and the second elastic damping frame 24 are both concave arc shapes. Together, they form an arc-shaped support surface. Compared with a planar support arm, it can distribute the concentrated load more evenly to multiple support points, greatly improving contact stability and effectively preventing the steel cage 1 from rolling.

[0032] The first elastic shock absorber 23 includes an inner arc channel steel 231, an outer arc channel steel 232, a rubber anti-vibration pad 233, and a channel steel support frame 234. The inner arc channel steel 231 is fixedly installed on the channel steel support frame 234. The outer arc channel steel 232 is installed on the inner arc channel steel 231 through several anti-vibration spring columns 4. The outer support surface of the outer arc channel steel 232 is covered with a rubber anti-vibration pad 233. The channel steel support frame 234 is slidably installed on the hollow steel truss 21 through an adjustment component 22. The outer arc channel steel 232 covers the inner arc channel steel 231. Anti-vibration spring columns 4 are welded inside the inner arc channel steel 231. Preferably, there are three anti-vibration spring columns 4. The other end of the spring is welded to the outer arc channel steel 232. The channel steel support frame 234 is directly connected to the adjustment component 22. It is responsible for transferring the load to the main truss and provides the main support and moving reference of the structure. The inner arc channel steel 231 is fixed to the channel steel support frame 234 by welding. The seismic spring column 4 connects the inner and outer channels steel, converting the vibration impact force transmitted from the steel cage 1 into the repeated expansion and contraction deformation of the spring, and absorbing and dissipating most of the energy in the process. The three arc-shaped seismic spring columns 4 can form a stable support point and effectively constrain the multi-directional displacement of the outer arc channel steel 232 to ensure the force balance. The outer arc channel steel 232 serves as the direct support surface of the shock-absorbing outer support 2 and maintains a small buffer gap with the inner arc channel steel 231. The rubber anti-vibration pad 233 is tightly attached with adhesive to provide a protective layer that is anti-slip and anti-scratch.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, the adjustment assembly 22 includes a handwheel 221, a bidirectional screw 222, and a limiting slide rail 223. The limiting slide rail 223 is fixedly installed on the hollow steel truss 21. The bidirectional screw 222 is rotatably installed inside the limiting slide rail 223. One end of the bidirectional screw 222 passes through the limiting slide rail 223 and is connected to the handwheel 221. The first elastic damping frame 23 and the second elastic damping frame 24 are both slidably installed inside the limiting slide rail 223 via the bidirectional screw 222. Each of the two channel steel support frames 234 is equipped with an internally threaded slider, which respectively engages with the left-hand threaded section and the right-hand threaded section on the bidirectional screw 222. The screw thread segments are precisely engaged. When the handwheel 221 is rotated clockwise, the bidirectional screw 222 rotates in the same direction. The first elastic damping frame 23 and the second elastic damping frame 24 move closer to each other synchronously and towards each other under the guidance of the limiting slide rail 223, thereby reducing the distance between them. When the handwheel 221 is rotated counterclockwise, the process is reversed. The screw rotates in the opposite direction, and the two sliders move away from each other synchronously and towards each other. The distance between the first and second elastic damping frames 24 increases, and the slider is restricted in the groove of the limiting slide rail 223. It can only move along the limiting slide rail 223 and cannot rotate with the screw.

[0034] like Figure 6 and Figure 7 As shown, the adjustable inner support 3 for energy dissipation includes a first adjustable energy dissipation rod 31, a second adjustable energy dissipation rod 32, and a third adjustable energy dissipation rod 33. The first adjustable energy dissipation rod 31, the second adjustable energy dissipation rod 32, and the third adjustable energy dissipation rod 33 have the same structure. One end of the first adjustable energy dissipation rod 31, one end of the second adjustable energy dissipation rod 32, and one end of the third adjustable energy dissipation rod 33 are all connected to a fixed point. The first adjustable energy dissipation rod 31, the second adjustable energy dissipation rod 32, and the third adjustable energy dissipation rod 33 form an inverted Y-shape. The structure is designed with adjacent angles of 120 degrees. The adjustable energy-dissipating inner brace 3 is supported by three identical adjustable energy-dissipating brackets forming a triangular shape, or a Y-shape with adjacent angles of 120 degrees. The fixing point where each end is fixed to the other is the center of the circle. The fixing is achieved by welding or high-strength bolts, thus forming a fixing point. The resultant force line of the three adjustable energy-dissipating brackets always passes through the center of the circle, ensuring that the stiffening hoop is subjected to pure positive pressure rather than eccentric force that will generate bending moment, thereby most effectively preventing the stiffening hoop from undergoing elliptical deformation.

[0035] The first adjustable energy-dissipating support rod 31 includes a hollow support rod 311, a support rod 312, a spring box 313, and a support plate 314. One end of the hollow support rod 311 is connected to a fixed point through the spring box 313, and the other end of the hollow support rod 311 is movably installed with the support rod 312 through an adjusting bolt. The support plate 314 is fixedly installed on the support rod 312. When vibration occurs during the transportation and hoisting of the steel cage 1, energy is dissipated through the spring box 313 to offset the deformation. The spring box 313 is a metal box with a compression spring inside. One end of the hollow support rod 311 passes through the spring box 313 and is connected to the compression spring inside the spring box 313. The spring box 313 and the hollow support rod 311 form an integral unit.

[0036] The passive retraction of the spring box 313 alone cannot achieve precise length matching. Therefore, active adjustment is required. Rotating the adjusting bolt can make the support rod 312 slide axially within the hollow support rod 311, thereby achieving precise fine-tuning of the extension length of the support plate 314. Vibration will occur during transportation, causing slight deformation of the steel cage 1. The spring box 313 allows the support to play a flexible shock absorption role, dissipating energy and offsetting deformation.

[0037] like Figure 6 As shown, a fixing rod is welded to the other side of the spring box 313. The second adjustable energy dissipation support rod 32 and the third adjustable energy dissipation support rod 33 have the same structure as the first adjustable energy dissipation support rod 31. The three fixing rods intersect to form a fixing point. The operator can press the three hollow support rods 311 or press only one of them to allow the whole to enter the interior of the steel cage 1. The pressure restriction is released, and the compression spring in the spring box 313 rebounds, pushing the hollow support rods 311 outward. This makes the three hollow support rods 311 supporting the adjustable energy dissipation inner support 3 at the same length inside the steel cage 1. Further manual fine-tuning is then performed until all the support plates 314 are completely and evenly attached to the inner side of the stiffening hoop of the steel cage 1.

[0038] The support plate 314 is arc-shaped, and the support rod 312 abuts against the stiffening hoop of the steel cage 1 through the support plate 314. The curvature of the support plate 314 matches that of the steel cage 1, ensuring surface contact with the stiffening hoop, greatly dispersing the pressure, preventing local crushing, and providing more stable circumferential restraint.

[0039] Example 2: An assembly method for a device to prevent deformation of steel cages during transportation due to vibration, such as... Figures 1-8 As shown, it includes the following steps: Step A: Determine the number and spacing of the shock-absorbing external supports 2 placed on the transport vehicle based on the length and weight of the steel cage 1; a1. Based on the drawing of steel cage 1, obtain the length parameters and total weight parameters of the steel cage 1 to be transported; a2, based on the length and total weight parameters of the steel cage 1, and according to the preset digital model of the load-bearing and damping of the external damping support 2, calculate the minimum number of external damping supports 2 required and the standard spacing between two adjacent external damping supports 2. The number of shock-absorbing external supports 2 increases with the increase of the total weight of the steel cage 1, and the spacing increases with the increase of the length of the steel cage 1 or decreases with the increase of the total weight, so as to ensure that the uniformly distributed load borne by each shock-absorbing external support 2 does not exceed its rated bearing value.

[0040] a3. Based on the calculated quantity and standard spacing, mark the installation positions of each shock-absorbing outer bracket 2 on the floor of the transport vehicle. The pre-prepared shock absorber brackets 2 are hoisted and installed at the marked installation positions, ensuring that the bottom surface of the shock absorber brackets 2 is tightly fitted to the floor of the carriage and fixed with bolts to ensure that the installation is firm and without shaking.

[0041] Step B: Determine the number of adjustable internal supports 3 for energy dissipation based on the stiffening hoops of the reinforcing cage 1; Based on the drawing of steel cage 1, obtain the total length parameters of steel cage 1 and the number of all stiffening hoops that are uniformly or non-uniformly distributed on it. Plan the total number of adjustable internal supports 3 for energy dissipation by setting one support between every three stiffening hoops.

[0042] Step C: Adjust the adjustable internal bracing 3 to provide internal support for the steel cage 1; c1. Place the steel cage 1 horizontally so that it is in an easy-to-operate state; Ensure that there are reliable temporary supports at both ends and in the middle of the steel cage 1 at this time, such as using sleepers, to prevent the steel cage 1 from rolling or overturning and causing a safety accident.

[0043] c2, press the hollow support rod 311 to retract some of the hollow support rod 311 into the spring box 313, and place them one by one into the internal cavity of the steel cage 1. The spatial position of each support energy dissipation adjustable inner support 3 is moved and adjusted by manual adjustment. c3, tighten the adjusting bolts in sequence to make the support rod 312 extend outward for fine adjustment, until the three support plates 314 of the energy dissipation adjustable inner support 3 are all firmly against the stiffening hoop of the steel cage 1, forming a radial support force on the inner wall of the steel cage 1. Tighten the adjusting bolts of the fixed number of turns in sequence to ensure that the extension length of the three support rods 312 is the same distance, so as to avoid the situation where one support plate is tightened while the other is still suspended, thereby achieving rigid support for the inside of the steel cage 1 until obvious resistance can be felt, indicating that the internal support has begun to bear the radial pressure from the steel cage 1, thereby suppressing the ellipticization or local buckling deformation caused by vibration during transportation.

[0044] Once all the adjustable internal supports 3 are installed, they form an internal truss support system inside the steel cage 1, providing strong radial support for the thin-walled cylindrical structure of the steel cage 1. This effectively suppresses the elliptic deformation or denting caused by vibration energy generated during transportation due to vehicle bumps, sudden braking, or turning, ensuring that the geometric dimensions and shape accuracy of the steel cage 1 still meet the design requirements when it arrives at the construction site, laying a solid foundation for the subsequent smooth lowering and concrete pouring.

[0045] Step D: Adjust the shock-absorbing external support 2 to support multiple steel cages 1; Based on the actual outer diameter parameters of multiple steel cages 1, turn the handwheel 221 to simultaneously adjust the radial extension and retraction of the first elastic shock absorber 23 and the second elastic shock absorber 24 on the hollow steel truss 21 until the support surface contour formed by the top of the first elastic shock absorber 23 and the second elastic shock absorber 24 fits the outer wall contour line of multiple steel cages 1, thereby providing stable support for multiple steel cages 1 during transportation.

[0046] The steel cage 1, which has been supported by the adjustable internal bracing 3, is hoisted onto the assembled shock-absorbing external support 2. By finely adjusting the position of the steel cage 1, the top support surface of the shock-absorbing external support 2 is precisely aligned with the bottom outline of the outer wall of the steel cage 1, providing external bottom support for the steel cage 1.

[0047] Step E: When unloading the steel cage 1, the shock absorber outer support 2 can be hoisted and temporarily stored at the same time; Before the transport vehicle is loaded and ready to be shipped, check whether all the adjustable inner supports 3 for energy dissipation are securely in place and whether all the outer supports 2 for shock absorption are securely installed. When unloading the steel cage 1, first remove the bolts that fix the outer supports 2 for shock absorption, release the outer supports 2 for shock absorption from the transport vehicle, and use gantry cranes or other lifting tools to lift multiple outer supports 2 and multiple steel cage 1 bodies placed on them at the same time. They are then transported as a whole unit from the transport vehicle to the temporary storage area. At this time, the adjustable inner supports 3 for energy dissipation and the outer supports 2 for shock absorption inside the steel cage 1 continue to play their temporary support role.

[0048] Step F: Dismantle the adjustable internal support 3 for energy dissipation inside the steel cage 1; Manually remove the adjustable inner support 3 for energy dissipation from the inside of the steel cage 1. The removal can be carried out by simply reversing step C. After inspecting, cleaning and maintaining the removed adjustable inner support 3, it can be temporarily stored or directly transported back to the designated location for subsequent reuse.

[0049] This greatly reduces the deformation of the steel cage 1 due to vibration during transportation. At the same time, it eliminates the need to use cross steel bars as internal supports, reducing the waste of steel raw materials and preventing the main reinforcement from opening due to hammering the internal support. It is also applicable to steel cages 1 of different lengths and diameters.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
