Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a limiting and transfer device for prefabricated building components. Background Technology

[0002] In the modern construction industry, prefabricated buildings have gradually become the mainstream of the construction industry due to their advantages of short construction cycle, stable quality and significant energy saving and environmental protection. Under this trend, the production, transportation and installation of prefabricated building components, as key links in prefabricated buildings, directly affect the efficiency and safety of the entire project.

[0003] Precast building component positioning and transfer devices use specific clamps, slots, and fixing devices to position and secure components, preventing displacement, shaking, or collisions during transportation, loading and unloading, and storage. This effectively protects the integrity of precast components and avoids quality issues such as chipped edges, cracks, etc. Currently, the specifications, dimensions, and shapes of precast components vary greatly in different building projects. Existing positioning and transfer devices are often designed for specific types or size ranges of components and are difficult to adapt to all types of precast components. Existing solutions design the positioning and transfer device as multiple independent modules, each with a specific function, such as a positioning module, a clamping module, and a support module. In actual use, these modules can be freely combined like building blocks according to the shape and size of the precast components. However, modular devices lack uniformity and flexible adjustment. When switching from positioning ultra-large bridge components to small precast staircases, a large-scale disassembly and reassembly of the entire device is required. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prefabricated building component limiting and transfer device, which aims to improve the problem of large-scale disassembly and reassembly of the entire device when switching from limiting ultra-large bridge components to small prefabricated stairs in existing modular devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated building component limiting and transfer device, comprising a storage box, wherein the top left and right sides of the storage box are provided with grooves, and the bottom front and rear sides of the two grooves are respectively provided with multiple sliding grooves, and a trapezoidal frame is provided between adjacent sliding grooves. The outer walls of the two trapezoidal frames are respectively fixedly connected to the front and rear sides, and the outer walls of the multiple sliding sliders are respectively slidably connected to the inner walls of the multiple sliding grooves. The bottom front and rear sides of the two trapezoidal frames are respectively fixedly connected to the bottom of the outer walls of the two trapezoidal frames. The bottom front and rear sides of the inner wall of the storage box are provided with multiple limiting grooves, and the inner walls of the multiple limiting grooves are provided with rotating wheels. The tops of the multiple rotating wheels are respectively fixedly connected to the bottoms of the two base plates. The four corners of the bottom of the outer wall of the storage box are fixedly connected to movable wheels. Two fixing mechanisms are provided in the middle of the bottom of the storage box, and the fixing mechanisms are used to fix the rotating wheels after they move to a designated position.

[0006] As a further description of the above technical solution:

Fixing plates are fixedly connected to the left and right sides of the outer walls of the two connecting rods, and fixing cylinders are fixedly connected to the tops of the two fixing plates. The left and right sides of the outer walls of the two fixing cylinders are provided with slots. Support columns are provided on the inner walls of the two fixing cylinders. Springs are fixedly connected to the middle of the inner walls of the two support columns. The left and right ends of the two springs are fixedly connected with locking blocks. The outer walls of the two locking blocks engage with the inner walls of the two slots.

[0008] As a further description of the above technical solution:

[0009] The storage box has a mounting slot on each of its front left and right sides, and a warning sign is fixedly connected to the inner wall of each of the two mounting slots.

[0010] As a further description of the above technical solution:

[0011] The storage box has mounting holes on its left and right sides, and push rods are fixedly connected to the inner walls of both mounting holes.

[0018] As a further description of the above technical solution:

[0019] The top of each of the two trapezoidal frames is provided with a second mounting groove, and the inner wall of each of the two second mounting grooves is fixedly connected with a handle.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the sliding connection between the slider and the groove allows the spacing of the trapezoidal frame to be flexibly adjusted, which can adapt to prefabricated components of various sizes, greatly improving the applicability of the device. The trapezoidal frame in the form of a staircase provides convenience for classifying and placing different components, improving space utilization.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a prefabricated building component limiting and transfer device, including a storage box 1. The top left and right sides of the storage box 1 are provided with grooves 3. The grooves 3 on the top of the storage box 1 primarily provide a spatial foundation for the subsequent placement of trapezoidal frame 5 components. Multiple sliding grooves 4 are respectively provided on the front and back sides of the bottom of the two grooves 3. These sliding grooves 4 are for sliding connection with the sliders 6 on the outer wall of the trapezoidal frame 5. The sliding grooves 4 provide a clear track for the movement of the sliders 6. Trapezoidal frames 5 are arranged between adjacent sliding grooves 4. Slider 6s are fixedly connected to the front and back sides of the outer walls of the two trapezoidal frames 5. The outer walls of the sliders 6 slide against the inner walls of the multiple sliding grooves 4. Multiple shock absorbers 7 are fixed to the front and back sides of the bottom of the two trapezoidal frames 5. The function of the shock absorbers 7 is to reduce the vibration impact on the trapezoidal frames 5 when the device moves or is subjected to external impact. The bottom of the outer wall of the trapezoidal frame 5 is fixedly connected to a base plate 8. The base plate 8 is fixed to the bottom of the outer wall of the trapezoidal frame 5, which serves to support and stabilize the trapezoidal frame 5. Multiple limiting grooves 10 are opened on the front and back sides of the bottom of the inner wall of the storage box 1. The inner wall of the multiple limiting grooves 10 is equipped with rotating wheels 9. The opening of the limiting grooves 10 provides a precise track for the movement of the rotating wheels 9. The top of the multiple rotating wheels 9 is fixedly connected to the bottom of the two base plates 8 respectively. The rotating wheels 9 cooperate with the slider 6. When the slider 6 slides in the sliding groove 4, the rotating wheels 9 move synchronously in the limiting grooves 10, realizing the smooth sliding of the trapezoidal frame 5. The four corners of the bottom of the outer wall of the storage box 1 are fixedly connected to moving wheels 11. The setting of moving wheels 11 makes the entire prefabricated building component limiting transfer device have good mobility. Two fixing mechanisms 2 are set in the middle of the bottom of the storage box 1. The fixing mechanisms 2 are used to fix the rotating wheels 9 after they move to the designated position.

[0032] Specifically, the storage box 1 serves as the carrier of the overall structure. The grooves 3 on the top left and right sides provide the necessary space for the movement of the trapezoidal frame 5. The multiple sliding grooves 4 on the front and back sides of the bottom of the grooves 3 cooperate with the sliders 6 fixed on the front and back sides of the outer wall of the trapezoidal frame 5. The sliders 6 slide in the sliding grooves 4, driving the trapezoidal frame 5 to move to both sides, increasing the spacing between the trapezoidal frames 5, which facilitates the retrieval and placement of large or more prefabricated components. The trapezoidal frame 5, which adopts a staircase shape, can classify and store different materials, improving space utilization. The shock absorbers 7 at the bottom of the trapezoidal frame 5 buffer vibrations during the movement of the device, protecting the prefabricated components from damage. The limiting groove 10 at the bottom of the inner wall of the storage box 1 is equipped with rotating wheels 9. The rotating wheels 9 are fixed to the base plate 8 and can assist the movement of the sliders 6. The limiting groove 10 provides a track for it, ensuring the stability of the movement of the trapezoidal frame 5. The moving wheels 11 at the four corners at the bottom of the storage box 1 facilitate the overall movement of the device and realize the flexible transfer of prefabricated components between different sites.

[0033] Reference Figure 2 , Figure 3 and Figure 5The fixing mechanism 2 includes two connecting rods 201. The tops of both connecting rods 201 are fixedly connected to the middle of the bottom of the storage box 1. The middle position is a relatively stable stress point for the storage box 1, making the support of the fixing mechanism 2 for the storage box 1 more stable. Fixing plates 202 are fixedly connected to the left and right sides of the outer walls of the two connecting rods 201, increasing the connection area between the connecting rods 201 and other components, making the connection between the subsequently connected fixing cylinder 203 and the connecting rods 201 more secure. Fixing cylinders 203 are fixedly connected to the tops of the two fixing plates 202, providing a stable installation space and moving track for the support column 205, allowing the support column 205 to move up and down inside. The left and right sides of the outer walls of the two fixing cylinders 203 are provided with slots 20. 4. The slot 204 provides a specific position for the block 207. When the block 207 is inserted into the slot 204, the support column 205 is fixed in the corresponding position inside the fixed cylinder 203, thereby maintaining the height stability of the storage box 1. The inner walls of the two fixed cylinders 203 are respectively provided with support columns 205. The middle part of the inner wall of the two support columns 205 is respectively fixedly connected with springs 206. The springs 206 are elastic and will apply an outward pushing force to the blocks 207 connected to both ends. This pushing force allows the blocks 207 to fit tightly against the inner wall of the fixed cylinder 203 and be inserted into the slot 204 in the appropriate position. The left and right ends of the two springs 206 are respectively fixedly connected with blocks 207. The outer walls of the two blocks 207 are respectively engaged with the inner walls of the two slots 204.

[0034] Specifically, the fixing mechanism 2 includes two connecting rods 201, whose tops are fixedly connected to the middle of the bottom of the storage box 1, providing direct vertical support for the storage box 1 and ensuring the stable placement of the storage box 1. The outer walls of the two connecting rods 201 are provided with fixing plates 202 on the left and right sides, which serve as a connecting transition and firmly connect the connecting rods 201 to the fixing cylinder 203. The fixing cylinder 203 connected to the top of the fixing plate 202 is a key component for adjusting and fixing the height of the support column 205. The slots 204 opened on the left and right sides of its outer wall are used to cooperate with the locking blocks 207 for positioning. The support column 205 is set on the inner wall of the fixing cylinder 203 and can move up and down along the fixing cylinder 203 to adapt to different height requirements. The spring 206 connected to the middle of the inner wall of the support column 205 is always in an elastic deformation state, providing an outward pushing force to the locking blocks 207. The locking blocks 207 connected to both ends of the spring 206 engage with the inner wall of the slot 204 under the pushing force of the spring 206, thereby fixing the support column 205 at the set height.

[0035] Reference Figure 1 , Figure 2 and Figure 4The storage box 1 has mounting slots 12 on both the left and right sides of its front end. Warning signs 13 are fixedly connected to the inner walls of both mounting slots 12. The mounting slots 12 have a positioning and fixing function, which can accurately define the installation position of the warning signs 13. The storage box 1 has mounting holes 14 on the left and right sides of its outer wall. Push rods 15 are fixedly connected to the inner walls of both mounting holes 14. By holding the push rods 15, the user can easily apply pushing or pulling force to the storage box 1, thereby changing the position of the storage box 1. Protective pads 16 are fixedly connected to the outer walls of the two push rods 15. The outer walls of the two protective pads 16 have multiple anti-slip textures 17. The protective pads 16 are usually made of soft and elastic material, which can cushion the pressure between the hand and the push rods 15.

[0036] Specifically, fixing the warning sign 13 to the inner wall of the mounting slot 12 ensures that the warning sign 13 is stable and not easy to fall off, and can clearly convey warning information to the user or people around, serving as a reminder to pay attention to the relevant situation of the storage box 1. After the push rod 15 is fixed to the inner wall of the mounting hole 14, it is convenient for the user to push the storage box 1 to move its position, making it convenient to use the storage box 1 in different scenarios. The protective pad 16 can buffer the pressure between the hand and the push rod 15, reducing the discomfort of the hand during the pushing process. The anti-slip texture 17 can effectively prevent the hand from sweating when pushing the storage box 1.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the storage box 1 has two connecting grooves 18 on the rear side. The inner walls of the two connecting grooves 18 are fixedly connected to reflective strips 19, which can reflect the surrounding light so that they can be clearly seen from a distance. The bottom ends of the two support columns 205 are fixedly connected to foot pads 20. The two foot pads 20 are rounded and play the role of dispersing pressure and providing stable support. The top of the two trapezoidal frames 5 is provided with mounting grooves 21. The inner walls of the two mounting grooves 21 are fixedly connected to handles 22. The mounting grooves 21 provide the handles 22 with accurate installation positions and a solid connection base, ensuring that the handles 22 can be stably fixed on the trapezoidal frames 5.

[0038] Specifically, fixing the reflective strip 19 to the inner wall of the connecting groove 18 ensures that the reflective strip 19 is in a stable position, reduces the friction between the foot pad 20 and the ground, and makes it easier to push or drag when the storage box 1 needs to be moved, while also preventing scratches on the ground. After the handle 22 is fixed to the inner wall of the mounting groove 21, the user can move the trapezoidal frame 5 by holding the handle 22.

[0039] Working principle: The slider 6 slides in the groove 4, which drives the trapezoidal frame 5 to slide to the side away from each other, increasing the distance between the two trapezoidal frames 5. Since the trapezoidal frame 5 adopts the form of a staircase, different materials are placed on it. When the trapezoidal frame 5 moves, the slider 6 fixed at the bottom moves, which drives the rotating wheel 9 to move in the limiting groove 10. The limiting groove 10 provides a moving track for the rotating wheel 9. At the same time, the shock absorber 7 at the bottom of the trapezoidal frame 5 can play a shock-absorbing and protective role for the materials placed on the trapezoidal frame 5. When it is necessary to move the entire device, the device can be moved by the moving wheels 11 at the four corners of the bottom of the outer wall of the storage box 1.

[0040] Furthermore, the fixing plate 202 on the outer wall of the connecting rod 201 connects to the fixing cylinder 203, ensuring that the fixing cylinder 203 is in a stable position. When fixation is required, the support column 205 is pressed down or adjusted. The spring 206 in the middle of the inner wall of the support column 205 is in a compressed state. The locking block 207 will slide on the inner wall of the fixing cylinder 203 as the support column 205 moves. When the locking block 207 moves to the position corresponding to the slot 204, the spring 206 restores its elastic deformation. The resulting elastic force pushes the locking block 207 outward, so that its outer wall is tightly engaged with the inner wall of the slot 204, thus fixing the support column 205 in a specific position inside the fixing cylinder 203. The bottom of the support column 205 contacts the ground, firmly fixing the device in the current position and preventing the rotating wheel 9 from continuing to move, thus ensuring the stability of the storage box 1 and the internal prefabricated components.
