Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a device for preventing deformation during the transfer of steel cages. Background Technology

[0002] In building construction, steel reinforcement cages are an important component of the building structure. Steel reinforcement cages are typically fabricated in steel bar processing plants and then transported to the construction site. If the cages deform during transport, it will affect their load-bearing capacity and stability within the building structure, reducing construction quality and increasing rework costs and time.

[0003] Currently, when transporting steel cages, it is common practice to lay pads at the bottom of the cargo compartment of the transport vehicle to provide support points and limit their sliding and rolling on the vehicle. Utility Model Content

[0004] The inventors found that while fixing the rebar cage using pads is a simple method, it is problematic when transporting it to mountainous construction sites where steep, uneven roads can easily cause the cage to slide or roll and collide with the cargo container, resulting in deformation. This simple fixing method cannot guarantee the integrity of the rebar cage's shape under complex transport conditions. Therefore, this invention addresses these problems by providing a rebar cage transport deformation prevention device that overcomes or at least partially solves these issues.

[0005] The present invention proposes a steel cage transfer anti-deformation device, comprising: a transfer frame and an internal support mechanism;

[0006] The transfer frame includes two support frames and a connecting rod assembly, with the two support frames arranged at relative intervals along the width direction of the transfer frame.

[0007] Each of the aforementioned support frames includes a support frame and a limiting arc rod, wherein the limiting arc rod is connected to the top of the support frame;

[0008] The connecting rod assembly connects the two support frames;

[0009] The internal support mechanism includes an internal support rod, which includes a rod body and fastening structures connected to both ends of the rod body. The length of the rod body is adjustable, and the fastening structures can be detachably connected to the reinforcing cage.

[0010] Optionally, the rod body includes a sleeve and two screws;

[0011] The two ends of the sleeve are respectively threaded to the two screws;

[0012] The ends of the two screws furthest from the sleeve are respectively connected to the fastening structure.

[0013] Optionally, the internal threads at both ends of the sleeve are rotated in opposite directions.

[0014] Optionally, the inner support mechanism further includes a connecting part, which has two connecting through holes. The axes of the two connecting through holes are perpendicular to each other and not collinear. Two inner support rods are provided, and the sleeves of the two inner support rods are respectively inserted into the two connecting through holes.

[0015] Optionally, the fastening structure includes a fixed lug and a movable lug;

[0016] The fixed ear plate is fixed to the end of the rod body, one end of the movable ear plate is hinged to the fixed ear plate, and the other end of the movable ear plate is connected to the fixed ear plate through a detachable connection structure.

[0017] Optionally, the fixed ear plate has a plurality of elastic limiting protrusions on the side facing the movable ear plate.

[0018] Optionally, each of the support frames includes a bottom rod extending along the length direction of the transfer frame and a plurality of support rods extending along the height direction of the transfer frame. The plurality of support rods are connected between the limiting arc rod and the bottom rod and are spaced apart along the length direction of the transfer frame.

[0019] Optionally, the connecting rod assembly includes a bottom connecting rod and a reinforcing connecting rod;

[0020] The bottom connecting rod is connected between the bottom rods of the two support frames;

[0021] The two opposite support rods in the two support frames are respectively connected by the reinforcing connecting rods.

[0022] Optionally, the reinforcing connecting rods at both ends along the length of the transfer frame are provided with slots for accommodating the limiting rods.

[0023] Optionally, the shape of the limiting arc rod is adapted to the shape of the reinforcing cage.

[0024] The beneficial effects of the above-mentioned technical solutions provided by the embodiments of this utility model include at least the following:

[0025] In the technical solution provided by this utility model, when it is necessary to transfer the reinforcing cage, the inner support rod can be adjusted to a suitable length, and then the fastening structures at both ends of the rod can be connected to the reinforcing cage respectively. This allows the reinforcing cage to be supported inside, preventing it from deforming under external forces and greatly improving its resistance to deformation. Furthermore, the inner support mechanism is detachably connected to the reinforcing cage and can be reused multiple times. The arc-shaped limiting rods can adapt well to the shape of the reinforcing cage, and under the weight of the reinforcing cage itself, the two limiting rods can limit the reinforcing cage from the outside, preventing it from moving and deforming after collisions during transportation. Therefore, after placing the inner support mechanism inside the reinforcing cage and then placing the reinforcing cage above the two limiting rods of the transfer frame, it can be transferred to the construction site. The transfer frame and internal support mechanism in this utility model greatly improve the anti-deformation effect of the steel cage during the transfer process by supporting and fixing both the inside and outside of the steel cage. It can be applied to transfer conditions with steep roads and uneven surfaces, ensuring the shape integrity of the steel cage under complex transfer conditions.

[0026] It is worth mentioning that after the rebar cage is transported to the construction site, the transfer frame can continue to be used to store the rebar cage, preventing it from touching the ground and thus preventing deformation. Furthermore, the transfer frame facilitates hoisting and transportation. Attached Figure Description

[0044] Currently, during the transfer of rebar cages, pads are typically laid at the bottom of the cargo compartment of the transport vehicle to provide support points and limit their sliding and rolling. The inventors discovered that the existing method of securing the rebar cages during transfer, using pads, is rather simple. However, when transferring them to construction sites in mountainous areas, the steep and uneven roads can easily cause the rebar cages to slide or roll and collide with the cargo compartment, resulting in deformation. This simple securing method cannot guarantee the integrity of the rebar cage's shape under complex transfer conditions.

[0045] To address this problem, the inventors attempted to design a deformation-preventing device for transporting reinforcing cages. They unexpectedly discovered that by placing the internal support mechanism inside the reinforcing cage and then placing the cage on the limiting arc rod of the transport frame, the deformation resistance of the reinforcing cage could be greatly improved. Furthermore, the cage's own weight provided a good limiting effect, making it suitable for transport conditions with steep roads and uneven surfaces, ensuring the shape integrity of the reinforcing cage under complex transport conditions. Based on this, this utility model provides a deformation-preventing device for transporting reinforcing cages. Figures 1 to 7 A specific embodiment of the steel cage transfer and deformation prevention device provided by this utility model.

[0046] Please see Figure 1 as well as Figures 5-7The reinforcing cage transfer anti-deformation device 100 provided by this utility model includes a transfer frame 1 and an internal support mechanism. The transfer frame 1 includes two support frames 11 and a connecting rod assembly 12, with the two support frames 11 arranged at intervals relative to each other along the width direction of the transfer frame 1. Each support frame 11 includes a support frame body 111 and a limiting arc rod 112, with the limiting arc rod 112 connected to the top of the support frame body 111. The connecting rod assembly 12 connects the two support frames 111. The internal support mechanism includes an internal support rod 2, which includes a rod body 21 and fastening structures 22 connected to both ends of the rod body 21. The length of the rod body 21 is adjustable, and the fastening structures 22 can be detachably connected to the reinforcing cage 200.

[0047] In the technical solution provided by this utility model, when the reinforcing cage 200 needs to be transported, the rod 21 of the inner support rod 2 can be adjusted to a suitable length, and then the fastening structures 22 at both ends of the rod 21 can be connected and fixed to the reinforcing cage 200 respectively. This allows the reinforcing cage 200 to be supported inside, preventing it from deforming under external forces, greatly improving its resistance to deformation. Moreover, since the inner support mechanism and the reinforcing cage 200 are detachably connected, they can be reused multiple times. The arc-shaped limiting arc rod 112 can adapt well to the shape of the reinforcing cage 200, and under the weight of the reinforcing cage 200 itself, the two limiting arc rods 112 can limit the reinforcing cage 200 from the outside, preventing it from moving and deforming after collision during transportation. Therefore, after the internal support mechanism is installed inside the steel cage 200, and the steel cage 200 is placed above the two limiting arc rods 112 of the transfer frame 1, the steel cage 200 can be transferred to the construction site.

[0048] It should be noted that the number of inner support rods 2 is not specifically limited and can be selected according to the actual situation. For some embodiments of this application, please refer to... Figure 2 The rod body 21 includes a sleeve 211 and two screws 212. Both ends of the sleeve 211 are threadedly connected to the two screws 212. The ends of the two screws 212 furthest from the sleeve 211 are connected to the fastening structure 22. Thus, the depth to which the screws 212 are screwed into the sleeve 211 can be adjusted by rotating the two screws 212, thereby adjusting the length of the rod body 21. This length adjustment is continuous during the adjustment process and can accommodate any length within the maximum length range, making it suitable for steel cages 200 of different diameters. Furthermore, when the rotation of the screws 212 stops, the screws 212 and the sleeve can form a self-locking mechanism, eliminating the need for an additional locking mechanism.

[0049] In some embodiments, the internal threads at both ends of the sleeve 211 rotate in opposite directions. Thus, after the fastening structures 22 at both ends of the rod 21 are respectively connected and fixed to the reinforcing cage 200, the sleeve 211 can be rotated around its own axis, allowing the screws 212 at both ends to move closer or further apart. To provide sufficient support to the reinforcing cage 200, the sleeve 211 can be adjusted to move the two screws 212 further apart, continuing to tighten the reinforcing cage 200, thereby further improving the deformation resistance of the reinforcing cage 200. Furthermore, to facilitate rotation of the sleeve 211 by the operator, multiple handles 2111 are provided on the outer side of the sleeve 211.

[0050] In some embodiments, the inner support mechanism further includes a connecting portion 3, which has two connecting through holes 31. The axes of the two connecting through holes 31 are perpendicular to each other and not collinear. Two inner support rods 2 are provided, and the sleeves 211 of the two inner support rods 2 are respectively inserted into the two connecting through holes 31. In this way, the two inner support rods 2 can be connected by the connecting portion 3 to form a cross-shaped structure to provide better support stability. Moreover, while the two inner support rods 2 form a cross-shaped structure, the operator can also rotate the sleeves 211 in the connecting through holes 31 without affecting the length adjustment of the rod 21. It is also worth mentioning that in some embodiments, handles 2111 are provided on both sides of the sleeve 211 at the connecting portion 3. The handles 2111 can be used as a limiting structure to prevent the sleeve 211 from sliding out of the connecting through holes 31. The handles 2111 are detachably connected to the sleeve 211, thereby also realizing the assembly and disassembly of the inner support rods 2 and the connecting portion 3.

[0051] In some embodiments of this application, the fastening structure 22 includes a fixed ear plate 221 and a movable ear plate 222. The fixed ear plate 221 is fixed to the end of the rod 21, one end of the movable ear plate 222 is hinged to the fixed ear plate 221, and the other end of the movable ear plate 222 is connected to the fixed ear plate 221 through a detachable connection structure 223. This fastening structure 22 has good durability and safety, is suitable for applications involving high-frequency disassembly and assembly or impact vibration, and is convenient and quick to assemble and disassemble. The method of the detachable connection structure 223 is not specifically limited. In this application, the fixed ear plate 221 and the movable ear plate 222 are respectively provided with mounting holes. By passing bolts through the mounting holes on the fixed ear plate 221 and the movable ear plate 222 respectively and connecting them with nuts, a detachable connection is achieved. In some embodiments, the fixed ear plate 221 has a plurality of elastic limiting protrusions 224 protruding on the side facing the movable ear plate 222. The elastic limiting protrusions 224 can increase the contact area between the fixed ear plate 221 and the reinforcing cage 200 and provide a certain elastic preload, which can improve the stability of the connection between the fastening structure 22 and the reinforcing cage 200, improve the support effect of the inner support mechanism on the reinforcing cage 200, and thus improve the deformation resistance of the reinforcing cage 200.

[0052] In some embodiments, each of the support frames 111 includes a bottom rod 1111 extending along the length of the transfer frame 1 and a plurality of support rods 1112 extending along the height of the transfer frame 1. The plurality of support rods 1112 are connected between the limiting arc rod 112 and the bottom rod 1111, and the plurality of support rods 1112 are spaced apart along the length of the transfer frame 1. Using a plurality of support rods 1112 to support the limiting arc rod 112 optimizes material usage while ensuring load-bearing strength, reducing production costs and the overall weight of the transfer frame 1, which is beneficial for transferring the reinforcing cage 200. Please refer to [link to relevant documentation]. Figure 1 Specifically, the multiple support rods 1112 include a first support rod 1113, a second support rod 1114, a third support rod 1115, a fourth support rod 1116, a fifth support rod 1117, a sixth support rod 1118, and a seventh support rod 1119 arranged from left to right. The two ends of the first support rod 1113 are respectively connected to the left end of the limiting arc rod 112 and the left end of the bottom rod 1111, and the two ends of the seventh support rod 1119 are respectively connected to the right end of the limiting arc rod 112 and the right end of the bottom rod 1111.

[0053] In some embodiments, the connecting rod assembly 12 includes a bottom connecting rod 121 and a reinforcing connecting rod 122; the bottom connecting rod 121 connects the bottom rods 1111 of the two support frames 111; and reinforcing connecting rods 122 connect opposite support rods 1112 of the two support frames 111. The two support frames 111 are connected into a single structure by the bottom connecting rod 121 and the reinforcing connecting rod 122. This structure is easy to manufacture, low in cost, highly practical, and provides stable support. Please refer to [link / reference]. Figure 1 as well as Figures 5-7 Specifically, multiple bottom connecting rods 121 are connected between two opposing bottom rods 1111. These multiple bottom connecting rods 121 are spaced apart along the length of the transfer frame 1, and a reinforcing diagonal rod 1211 is also connected between adjacent bottom connecting rods 121. In the two support frames 111, two first reinforcing connecting rods 1222, spaced apart along the height direction, are connected between two opposing first support rods 1113; a second reinforcing connecting rod 1223 is connected between two opposing second support rods 1114; a third reinforcing connecting rod 1224 is connected between two opposing third support rods 1115; a fourth reinforcing connecting rod 1225 is connected between two opposing fifth support rods 1117; a fifth reinforcing connecting rod 1226 is connected between two opposing sixth support rods 1118; and two sixth reinforcing connecting rods 1227, spaced apart along the height direction, are connected between two opposing seventh support rods 1119.

[0054] To limit the movement of the reinforcing cage 200 along its axial direction during transfer, in some embodiments, the reinforcing connecting rods 122 at both ends along the length of the transfer frame 1 are provided with slots 1221 for accommodating the limiting rods. After the reinforcing cage 200 is placed on the transfer frame 1, the limiting rod can first pass through the slot 1221 on one end of the reinforcing connecting rod 122, then through the reinforcing cage 200, and finally through the slot 1221 on the other end of the reinforcing connecting rod 1222. This limiting rod restricts the movement of the reinforcing cage 200 along its axial direction, preventing deformation caused by collision with the cargo box due to movement along its axial direction. Please refer to [link to relevant documentation]. Figure 1 as well as Figures 5-7 Both first reinforcing connecting rods 1222 are provided with slots 1221, and both sixth reinforcing connecting rods 1227 are provided with slots 1221.

[0055] In order to enhance the limiting effect of the limiting arc rod 112 on the reinforcing cage 200, in some embodiments, the shape of the limiting arc rod 112 is adapted to the shape of the reinforcing cage 200.
