Description

A rebar cage lifting bar recycling device Technical Field

[0001] This utility model relates to the field of steel bar recycling technology, and in particular to a steel cage steel bar recycling device. Background Technology

[0002] A steel reinforcement cage is a steel skeleton made by binding or welding steel bars according to certain specifications and shapes in order to enhance the load-bearing capacity and stability of concrete structures during construction. In bridge pile foundations, building foundations and other projects, the steel reinforcement cage is an important part of the pile body or foundation structure, and the first lifting bar is a key component connecting the steel reinforcement cage and the lifting equipment.

[0003] Currently, in traditional steel cage hoisting operations, the hoisting bars are usually made of steel bars of the same or similar specifications as the main steel bars of the steel cage. After completing a hoisting task, these hoisting bars are often unable to be effectively recovered from the construction site due to limitations in design, construction technology, and other factors, which undoubtedly increases the cost of construction materials significantly. At the same time, different engineering projects have significant differences in geological conditions, pile foundation depth, construction site environment, etc., and the length requirements of the hoisting bars during the steel cage hoisting process are also different. However, traditional hoisting bars are usually designed with a fixed length, and the length is determined based on experience or preliminary estimation during the manufacturing process. Once the manufacturing is completed, the length cannot be adjusted. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that in the prior art, during the hoisting operation of steel cages, the hoisting bars cannot be recycled and reused, and the length of the hoisting bars cannot be adjusted.

[0005] To solve the above-mentioned technical problems, this utility model provides a rebar cage lifting bar recovery device, which includes a lifting assembly and an adjustment assembly. The lifting assembly is located below the adjustment assembly. The lifting assembly includes a rebar cage, a first lifting bar, and a first lifting ring. There are two first lifting bars. The top two ends of the rebar cage are respectively connected to the first lifting bars. The top of each first lifting bar is connected to a first lifting ring, which is used to connect to the adjustment assembly. The adjustment assembly is located above the lifting assembly. There are two adjustment assemblies. Each adjustment assembly includes a second lifting bar, a shackle, and a fastener. One end of the second lifting bar is connected to the shackle, and the other end of the second lifting bar is connected to the fastener. The fastener is used to adjust the length of the second lifting bar in the vertical direction, and the bottom of the second lifting bar in the vertical direction passes through the first lifting ring and connects to the lifting assembly.

[0006] In one embodiment, the lifting assembly further includes a concrete layer poured inside the reinforcing cage, the concrete layer having a vertical elevation lower than the vertical elevation of the first lifting bar.

[0007] In one embodiment, the adjusting assembly further includes a second lifting ring, which is disposed at the top of the first lifting rod in the vertical direction, and one end of the shackle is fixedly connected to the first lifting rod, while the other end is detachably connected to the second lifting ring.

[0008] In one embodiment, the shackle includes a main body and a flipping part. The flipping part is disposed on the top of the main body and is rotatably connected to the main body. One end of the flipping part near the main body flips inward toward the main body. The flipping part is used for detachably connecting a second lifting ring.

[0009] In one embodiment, the shackle also includes a fixing part, which is fixedly connected to the main body, and one end of the fixing part has a fixing hole for fixing one end of the second lifting rod.

[0010] In one embodiment, the fastener includes a fixing ring and a locking buckle. The fixing ring is disposed above the locking buckle, and the other end of the second lifting rod is wrapped around the outer periphery of the fixing ring. There are multiple locking buckles, which are spaced apart in the vertical direction. The locking buckles are used to fix the folded part of the second lifting rod that is wrapped around the fixing ring. The fastener provides adjustment of the length of the folded part of the second lifting rod in the vertical direction, thereby adjusting the lifting length of the second lifting rod in the vertical direction.

[0011] In one embodiment, a first rubber tube is fitted around the outer periphery of the first suspension rod to prevent the first suspension rod from being contaminated by the outside.

[0012] In one embodiment, a second rubber tube is sleeved around the outer periphery of the second suspension rod, and the second rubber tube is detachably connected to the second suspension rod. The second rubber tube is used to prevent the second suspension rod from being contaminated by the outside.

[0013] Furthermore, the length of the second suspension rod in the vertical direction is equal to the length of the first suspension rod in the vertical direction.

[0014] Compared with the prior art, the present invention discloses a rebar cage lifting rod recycling device, which has the following advantages: the adjusting component allows for flexible adjustment of the length of the second lifting rod, enabling construction personnel to accurately adjust the horizontal and vertical positions of the rebar cage according to the actual construction scenario, such as pile holes of different depths or complex construction terrain, ensuring that the rebar cage is accurately lowered to the design elevation and reducing rework caused by positional deviations; with the setting of the first and second lifting rods, after the rebar cage hoisting and subsequent construction procedures are completed, the operator only needs to remove the second lifting rod by unfastening the fasteners, and then pull out the first lifting rod and the first lifting ring through the second lifting rod to easily recycle the first lifting rod. Compared with the traditional method, no additional tools or complex operations are required, greatly simplifying the recycling process and improving construction efficiency. The recycling and reuse of the first lifting rod is in line with the concept of sustainable development, reducing the consumption of metal resources and reducing the environmental damage caused by the mining and processing of new metal materials, thus having significant environmental benefits.

[0024] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0025] As shown in Figures 1 to 4, the present invention preferably provides a rebar cage lifting bar recovery device, which includes a lifting assembly 10 and an adjusting assembly 20. The lifting assembly 10 is located below the adjusting assembly 20. The lifting assembly 10 includes a rebar cage 11, a first lifting bar 12, and a first lifting ring 13. There are two first lifting bars 12. The top two ends of the rebar cage 11 are respectively connected to the first lifting bars 12. The top of each first lifting bar 12 is connected to a first lifting ring 13. The first lifting ring 13 is used to connect to the adjusting assembly 20. The adjusting assembly 20 is located above the lifting assembly 10. There are two adjusting assemblies 20. Each adjusting assembly 20 includes a second lifting bar 21, a shackle 22, and a fastener 23. One end of the second lifting bar 21 is connected to the shackle 22, and the other end of the second lifting bar 21 is connected to the fastener 23. The fastener 23 is used to adjust the length of the second lifting bar 21 in the vertical direction, and the bottom of the second lifting bar 21 in the vertical direction passes through the first lifting ring 13 and connects to the lifting assembly 10.

[0026] Based on the above technical features, this utility model embodiment allows for flexible adjustment of the length of the second lifting rod 21 via the fastener 23 in the adjusting component 20. Construction personnel can precisely adjust the horizontal and vertical positions of the rebar cage 11 according to the actual construction scenario, such as pile holes of different depths or complex construction terrain, ensuring that the rebar cage 11 is accurately lowered to the design elevation and reducing rework caused by positional deviations. With the setting of the first lifting rod 12 and the second lifting rod 21, after the rebar cage 11 is hoisted and subsequent construction procedures are completed, the operator only needs to remove the second lifting rod 21 by unfastening the fastener 22, and pull out the first lifting rod 12 and the first lifting ring 13 through the second lifting rod 21 to easily recover the first lifting rod 12. Compared with the traditional method, no additional tools or complex operations are required, greatly simplifying the recovery process and improving construction efficiency. The recycling and reuse of the first lifting rod 12 conforms to the concept of sustainable development, reduces the consumption of metal resources, and reduces the environmental damage caused by the mining and processing of new metal materials, thus having significant environmental benefits.

[0027] As shown in Figure 1, as part of some embodiments of this utility model, the hoisting assembly 10 also includes a concrete layer 14, which is poured inside the reinforcing cage 11. The vertical elevation of the concrete layer 14 is lower than that of the first lifting rod 12. The lower pouring height of the concrete layer 14 compared to the first lifting rod 12 ensures that the first lifting rod 12 is not encased in concrete after pouring. This eliminates the need for additional concrete removal during subsequent recovery of the first lifting rod 12, allowing operators to directly disassemble and recover it via the adjustment assembly 20, greatly simplifying the recovery process and improving efficiency. The concrete layer 14 forms a robust filling within the reinforcing cage 11, enhancing its overall rigidity and strength. During hoisting, the concrete layer 14 and the reinforcing cage 11 share the load, effectively reducing deformation caused by the cage's own weight or external forces, ensuring structural stability during hoisting and lowering, and enabling accurate positioning.

[0028] As shown in Figure 2, as part of some embodiments of this utility model, the adjusting assembly 20 further includes a second lifting ring 24. The second lifting ring 24 is disposed at the top of the first lifting rod 12 in the vertical direction, and one end of the shackle 22 is fixedly connected to the first lifting rod 12, while the other end is detachably connected to the second lifting ring 24. By using the second lifting ring 24, the shackle 22 and the second lifting ring 24 are detachably connected, making the assembly and disassembly process of the adjusting assembly 20 and the lifting assembly 10 simpler and faster. On the construction site, construction personnel can quickly complete the connection or separation operation between the two without the need for complex tools, greatly shortening the construction preparation and finishing time and improving construction efficiency. The second lifting ring 24 increases the flexibility of the connection part; the shackle 22 can rotate relative to the second lifting ring 24 within a certain range, thereby allowing the second lifting rod 21 to connect to the first lifting rod 12 at different angles. This flexibility allows the device to adapt to various complex construction environments and the posture of the steel cage 11. For example, when encountering situations such as pile hole tilting or the steel cage 11 needing to be hoisted at a special angle, the stability and safety of the hoisting process can still be ensured.

[0029] As shown in Figure 4, as an embodiment of this utility model, the shackle 22 includes a main body 221 and a flipping part 222. The flipping part 222 is disposed on the top of the main body 221 and is rotatably connected to the main body 221. The end of the flipping part 222 near the main body 221 flips inward toward the main body 221. The flipping part 222 is used for detachably connecting the second lifting ring 24. With the main body 221 and the flipping part 222, the flipping part 222 of the shackle 22 is rotatably connected to the main body 221. Flipping inward toward the main body 221 achieves a detachable connection with the second lifting ring 24. Compared with traditional fixed connectors, this eliminates the need for complex steps such as tightening and loosening bolts or multiple alignment of clips. On the construction site, operators only need one hand or simple tools to easily complete the flipping action, which can quickly complete the connection and disassembly work during hoisting or retrieval, significantly improving construction efficiency.

[0030] As shown in FIG4, as an embodiment of the present invention, the shackle 22 further includes a fixing part 223, which is fixedly connected to the main body 221, and a fixing hole is provided at one end of the fixing part 223 for fixing one end of the second lifting rod 21. The fixing part 223 forms a rigid connection with the end of the second lifting rod 21 through the fixing hole, which complements the flexible connection formed by the main body 221 and the flipping part 222, effectively ensuring the stability of the connection between the shackle 22 and the second lifting rod 21.

[0031] As shown in FIG3, as some embodiments of the present utility model, the fastener 23 includes a fixing ring 231 and a lock 232. The fixing ring 231 is disposed above the lock 232, and the other end of the second lifting rod 21 is wrapped around the outer periphery of the fixing ring 231. There are multiple locks 232, which are spaced apart in the vertical direction. The locks 232 are used to fix the folded part of the second lifting rod 21 wrapped around the fixing ring 231. The fastener 23 provides adjustment of the length of the folded part of the second lifting rod 21 in the vertical direction, thereby adjusting the lifting length of the second lifting rod 21 in the vertical direction. With multiple locking buckles 232 spaced vertically, construction workers can quickly fix the folded part of the second lifting rod 21 to the locking buckles 232 at different heights according to actual hoisting needs. This allows for easy adjustment of the hoisting length of the second lifting rod 21. The locking buckles 232 are spaced apart and clearly positioned, allowing construction workers to intuitively snap the folded part of the second lifting rod 21 into the corresponding locking buckle 232 based on the site elevation or measurement data. This reduces length adjustment errors caused by operational mistakes and improves construction accuracy and efficiency. The second lifting rod 21 is wrapped around the outer circumference of the fixing ring 231 and fixed by the locking buckles 232. This installation method is simple and direct, requiring no complex connection processes or tools. During disassembly, simply open the locking buckles 232 and remove the second lifting rod 21 from the fixing ring 231. Compared to traditional welding or bolt connections, this method is more convenient and reduces labor costs and intensity.

[0032] As shown in Figure 1, as part of some embodiments of this utility model, a first rubber tube is sleeved around the outer periphery of the first lifting rod 12. The first rubber tube is used to prevent the first lifting rod 12 from being contaminated by the outside environment. During the pile foundation drilling and grouting process, the mud contains a large amount of clay, additives and drill cuttings. The first rubber tube can isolate the mud from direct contact with the first lifting rod 12, avoid corrosive substances in the mud from eroding the metal surface and prevent rust spots from forming.

[0033] As shown in Figure 1, as part of some embodiments of this utility model, a second rubber tube is sleeved around the outer periphery of the second suspension rod 21, and the second rubber tube is detachably connected to the second suspension rod 21. The second rubber tube is used to prevent the second suspension rod 21 from being contaminated by the outside. Similarly, by setting the second rubber tube, the second rubber tube can isolate the mud from direct contact with the second suspension rod 21, effectively extending the service life of the second suspension rod 21.

[0034] Furthermore, the length of the second lifting bar 21 in the vertical direction is equal to the length of the first lifting bar 12 in the vertical direction. The first lifting bar 12 and the second lifting bar 21 have the same length in the vertical direction, which ensures that the tension at both ends of the steel cage 11 is uniform during hoisting, avoids the cage from tilting or twisting due to length differences, and reduces the risk of structural deformation.

[0035] In summary, the present invention provides a rebar cage lifting rod recycling device. Compared with the prior art, its advantages are as follows: the buckle 23 in the adjusting component 20 can flexibly adjust the length of the second lifting rod 21. Construction personnel can accurately adjust the horizontal and vertical positions of the rebar cage 11 according to the actual construction scenario, such as pile holes of different depths and complex construction terrain, to ensure that the rebar cage 11 is accurately lowered to the design elevation and reduce rework caused by position deviation. With the setting of the first lifting rod 12 and the second lifting rod 21, after the rebar cage 11 is hoisted and subsequent construction procedures are completed, the operator only needs to remove the second lifting rod 21 by unfastening the buckle 22, and pull out the first lifting rod 12 and the first lifting ring 13 through the second lifting rod 21 to easily recycle the first lifting rod 12. Compared with the traditional method, no additional tools or complicated operations are required, which greatly simplifies the recycling process and improves construction efficiency. The recycling and reuse of the first lifting rod 12 is in line with the concept of sustainable development, reduces the consumption of metal resources, and reduces the damage to the environment caused by mining and processing new metal materials, which has significant environmental benefits.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
