Description

Technical Field

[0001] This invention relates to the technical field of building construction, specifically to a reusable adjustable beam storage device and its installation method. Background Technology

[0002] Box girders are a type of beam commonly used in bridge construction. The middle part of a box girder is hollow, and the upper two sides are equipped with flange structures that resemble wings and extend from the middle of the box girder to both sides.

[0003] Currently, the pedestals used to store box girders at various beam yards are made of cast concrete. After the project is completed, these pedestals can only be disposed of as waste and cannot be recycled. Furthermore, because some are buried underground, they seriously hinder land reclamation and restoration. The installation of these pedestals requires multiple processes, including foundation treatment, prefabrication, backfilling, and testing, resulting in a long processing cycle, high installation losses, and difficulty in achieving the desired performance. Summary of the Invention

[0004] The purpose of this invention is to provide a reusable adjustable beam storage device and its installation method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Also includes:

[0008] An elastic driven mechanism is located within the platform structure and connected to multiple sets of sliding engagement mechanisms located within the platform structure. The elastic driven mechanism is triggered when the box girder is hoisted onto the platform structure and can cause the sliding engagement mechanisms to move.

[0009] An extension mechanism is provided at the bottom of the base in multiple sets. The extension mechanism is connected to the sliding engagement mechanism. When the sliding engagement mechanism moves, it can drive the extension mechanism to perform an extension movement towards the outside of the platform structure, so as to increase the floor area of ​​the platform structure.

[0010] Multiple sets of elastic locking mechanisms are provided on the sand box. The elastic locking mechanisms cooperate with the extension mechanisms and are triggered after the extension movement of the extension mechanisms is completed, so that the multiple sets of extension mechanisms remain in the extended state.

[0011] A lateral pressure mechanism is connected to the elastic driven mechanism and can cooperate with the platform. The lateral pressure mechanism can be triggered when the elastic locking mechanism moves and apply pressure to the side of the box girder.

[0012] As a further embodiment of the present invention: the elastic driven mechanism includes a cylinder disposed in the sand box, a boss slidably disposed in the cylinder, a telescopic rod fixed to the boss and slidably fitted with the cylinder, and a first cylindrical spring disposed in the cylinder.

[0013] The boss is connected to the sliding engagement mechanism. One end of the first cylindrical spring is connected to the boss, and the other end is connected to the inner wall of the cylinder. The telescopic rod passes through the top of the platform and is slidably connected to the platform. A support plate is fixedly installed at the end of the telescopic rod away from the boss. The top of the platform is provided with a groove that matches the support plate.

[0014] As a further embodiment of the present invention: the sliding fit mechanism includes a driven shaft rotatably mounted on the outer wall of the cylinder and a column fixedly mounted on the outer wall of the boss;

[0015] The driven shaft is connected to the extension mechanism, and a groove is provided on the outer wall of the driven shaft. The column extends into the groove and is slidably connected to the driven shaft. The groove includes an inclined section and a vertical section connected together. The vertical section is parallel to the central axis of the driven shaft. The cylinder is provided with a strip-shaped through groove for the column to move.

[0016] As a further embodiment of the present invention: the extension mechanism includes a drive rod fixedly installed at one end of the driven shaft, an extension plate slidably fitted into the bottom of the base, and a connecting rod connecting the extension plate and the drive rod;

[0017] One end of the connecting rod is rotatably connected to the extension plate, and the other end is rotatably connected to the end of the driving rod away from the driven shaft. The extension plate is also provided with a through hole that cooperates with the elastic locking mechanism.

[0018] As a further embodiment of the present invention: the elastic locking mechanism includes an assembly plate fixedly disposed on the sand box, a locking rod slidably disposed on the assembly plate, and a second cylindrical spring sleeved on the outer periphery of the locking rod;

[0019] The locking rod is adapted to the through hole, and a ring is fixedly installed on the locking rod. The two ends of the second cylindrical spring are respectively connected to the ring and the assembly plate. One end of the locking rod abuts against the extension plate, and the other end is provided with a pull ring.

[0020] As a further embodiment of the present invention: the supporting plate is provided with an opening, the lateral pressure mechanism includes a horizontal plate slidably disposed in the opening, an inclined plate is fixed at one end of the horizontal plate, the inclined plate is slidably attached to the base, and a pressure component is provided at the other end.

[0021] As a further embodiment of the present invention: the pressure application component includes a plurality of mounting sleeves fixedly installed on the horizontal plate and a plurality of horizontal columns respectively disposed in the mounting sleeves, the horizontal columns being interference-fitted with the mounting sleeves, and the ends of the plurality of horizontal columns away from the horizontal plate being provided with pressure plates.

[0022] An installation method for the reusable adjustable beam storage device includes the following steps:

[0023] Step 1, foundation treatment: Using the positioning center as a reference, drive piles into the ground at an angle of 40-50°, ensuring that the piles are driven to the same depth and angle in each direction.

[0024] Step 2: Install the base. The pile body is compacted using a tamping machine. Standard sand dunes are placed, and the base is placed on the dunes. The standard sand is adjusted to level the pile body. After leveling, the base is welded and fixed to the pile body.

[0025] Step 3: Install the pedestals. Position the pedestals on the base and place them in the center of the base. Adjust the height of the pedestals by adjusting the standard sand to ensure that the four pedestals are at the same level before placing the box girder.

[0026] Step 4: Install the far-infrared alarm system. After the box girder is placed, install the far-infrared alarm system at the center of the bottom of the box girder. The system will emit infrared rays outward from the center, ensuring that the four pedestals are at the same horizontal level.

[0027] Beneficial Effects: Compared with existing technologies, the adjustable beam storage device of this invention features a novel design. The platform is fabricated in a workshop, and large-scale processing equipment significantly shortens the processing cycle. On-site installation requires only foundation piling; the platform base, sand box, and platform can be installed using a crane. After installation, leveling can be achieved using the sand bin, which is convenient and quick. Furthermore, after project completion, the platform can be disassembled and reused in the next project, reducing the overall project cost. Because of the platform's reusability, it does not affect land reclamation and restoration, making it suitable for widespread use. Attached Figure Description

Detailed Implementation

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0039] Please see Figures 1-8 The reusable adjustable beam storage device described in this embodiment includes a base 1, a sand box 2 disposed on the base 1, and a platform 3 disposed on the sand box 2, which together form a platform structure for supporting the box beam.

[0040] The reusable adjustable beam storage device also includes:

[0041] An elastic driven mechanism is located within the platform structure and connected to multiple sets of sliding engagement mechanisms located within the platform structure. The elastic driven mechanism is triggered when the box girder is hoisted onto the platform structure and can cause the sliding engagement mechanisms to move.

[0042] An extension mechanism is provided at the bottom of the base 1 in multiple sets. The extension mechanism is connected to the sliding engagement mechanism. When the sliding engagement mechanism moves, it can drive the extension mechanism to perform an extension movement toward the outside of the platform structure, so as to increase the floor area of ​​the platform structure.

[0043] Multiple sets of elastic locking mechanisms are provided on the sand box 2. The elastic locking mechanisms cooperate with the extension mechanisms and are triggered after the extension movement of the extension mechanisms is completed, so that the multiple sets of extension mechanisms remain in the extended state.

[0044] A lateral pressure mechanism is connected to the elastic driven mechanism and can cooperate with the platform 3. The lateral pressure mechanism can be triggered when the elastic locking mechanism moves and apply pressure to the side of the box girder.

[0045] It should be noted that the platform structure is made of steel and is shaped like a frustum. The surface is treated with anti-corrosion to adapt to harsh environments and improve durability. The platform structure is designed to be narrower at the top and wider at the bottom, which increases the stability of the entire device and helps to distribute the pressure to the base 1, thus reducing the deformation coefficient.

[0046] To facilitate the leveling of the box girder, a hydraulic device can be installed inside the platform structure, which can be used for the automatic lifting and leveling of the entire platform.

[0047] It should be emphasized that any changes in the shape of the platform structure, such as square, rectangular, circular, hexagonal, or elliptical, are embodiments obtained by those skilled in the art without creative effort, and all fall within the scope of protection of this invention.

[0048] Secondly, as an example, the base is welded from 20mm thick steel plates, with dimensions of 2200*2500*400mm and a single weight of 2041.88kg. Four bases are required for each beam. The base 1 consists of a web, top plate, transverse stiffeners, longitudinal stiffeners, and diagonal stiffeners. Lifting holes are provided at the stiffeners for easy installation and disassembly. Because the base 1 needs to bear a significant weight, full penetration welding is required to minimize deformation. The stiffeners are distributed in a radiating pattern. A sand-draining port is provided at the bottom of the base 1's frame, with an M30 nut welded to the port. When not in use, an M30 bolt is tightened at the port. When unevenness occurs at the four corners of the box girder base, the bolts are unscrewed to allow self-leveling.

[0049] The sand box 2 is an open-type trough structure filled with standard sand. The sand box 2 measures 900*1200*250mm and is welded from 20mm thick steel plates. The sand box structure consists of a web plate and a bottom plate. Each web plate has two openings at its bottom end, with M20 threads machined into the openings. When not in use, M20 bolts are tightened into the openings. When unevenness occurs at the four corners of the box girder base, the bolts are unscrewed to allow self-leveling.

[0050] During actual construction, in order to ensure the bearing capacity of the foundation, piles need to be driven into the ground. The steel pipes used are φ118*6 round pipes. Due to different geological environments, when encountering harsh geological environments, the bearing capacity can be increased by adding column steel pipe piles.

[0051] To ensure the stability of the foundation, this invention improves the steel pipe pile by modifying the existing pointed portion of the steel pipe pile into a hinged mechanism. During pile driving, when the steel pipe pile reaches the predetermined position, lime is filled into the pile to expand it, causing the pointed end of the pile to split into petal-like shapes, increasing the pile's stability. Simultaneously, after the hinged steel pipe pile completes its working task and is retrieved, the spread end automatically retracts when lifted by external force, facilitating its removal from the ground for reuse.

[0052] Furthermore, an infrared alarm system is installed at the center of the bottom of the box girder. This system consists of an alarm host and infrared detectors. The infrared alarm actively emits infrared rays. When the infrared rays encounter an obstacle, they bounce back and are received by the alarm's detector. If the detector detects that the infrared rays are stationary—that is, continuously emitting red rays that bounce back—the alarm will not sound. The infrared rays are used to locate and level the girder storage platform. When the platform equipment sinks and violates this invisible red line, the detector will detect the abnormality and sound an alarm. This device dynamically monitors the girder storage platform equipment throughout its use, ensuring its safety.

[0053] In summary, the beam storage device proposed in this application uses a metal base instead of a reinforced concrete base to minimize the consumption of concrete and rocks and energy loss.

[0054] The beam storage equipment can be manufactured in the workshop, with large-scale processing equipment significantly shortening the processing cycle. On-site installation requires only piling; the base 1, sand box 2, and platform 3 can be installed using a crane. After installation, leveling can be achieved using the sand bins, making it convenient and quick. During use, a far-infrared alarm system monitors movement in real time, automatically triggering an alarm when deviations occur, reducing manual intervention and improving efficiency. Furthermore, after project completion, the equipment can be disassembled and reused in the next project, reducing the overall project cost and not affecting land reclamation and restoration.

[0055] When the box girder is hoisted onto the platform structure, the elastic driven mechanism will be triggered. The elastic driven mechanism will then engage with the sliding engagement mechanism, causing the sliding engagement mechanism to move. Correspondingly, the sliding engagement mechanism will drive the extension mechanism to move, and multiple sets of extension mechanisms will extend outwards towards the platform structure. After the box girder is hoisted, the elastic locking mechanism will be triggered, keeping the multiple sets of extension mechanisms in an extended state. This increases the footprint of the platform structure, further enhancing the stability of the equipment.

[0056] At the same time, the elastic driven mechanism drives the lateral pressure mechanism to move, so that the lateral pressure mechanism applies pressure to the box girder. In actual construction, a beam needs to be supported by four devices. Then, the lateral pressure mechanisms located on both sides of the box girder will simultaneously apply pressure to the middle of the box girder, which has a certain clamping effect and effectively improves the stability of the box girder when it is stored.

[0057] Please refer to it again. Figure 5The elastic driven mechanism includes a cylinder 6 disposed in the sand box 2, a boss 28 slidably disposed in the cylinder 6, a telescopic rod 7 fixed to the boss 28 and slidably fitted with the cylinder 6, and a first cylindrical spring 8 disposed in the cylinder 6.

[0058] The boss 28 is connected to the sliding engagement mechanism. One end of the first cylindrical spring 8 is connected to the boss 28, and the other end is connected to the inner wall of the cylinder 6. The telescopic rod 7 passes through the top of the base 3 and is slidably connected to the base 3. A support plate 5 is fixedly installed at the end of the telescopic rod 7 away from the boss 28. The top of the base 3 is provided with a groove 4 that matches the support plate 5.

[0059] When the box girder is hoisted onto the platform structure, the supporting plate 5 first contacts the bottom of the box girder. As the box girder descends, the telescopic rod 7 gradually moves toward the inside of the cylinder 6. Correspondingly, the first columnar spring 8 is compressed, and as the boss 28 slides downward in the cylinder 6, it triggers the sliding engagement mechanism. Then, the sliding engagement mechanism can drive the extension mechanism to perform an extension movement toward the outside of the platform structure, thereby increasing the floor area of ​​the platform structure and further improving the stability of the entire device.

[0060] Once the box girder is securely placed, the supporting plate 5 is positioned within the groove 4, so that the top of the pedestal 3 forms a complete flat surface, ensuring the stability of the box girder during storage.

[0061] Please refer to it again. Figure 5 , Figure 6 as well as Figure 8 The sliding fit mechanism includes a driven shaft 11 rotatably mounted on the outer wall of the cylinder 6 and a column 9 fixedly mounted on the outer wall of the boss 28.

[0062] The driven shaft 11 is connected to the extension mechanism, and a groove is provided on the outer wall of the driven shaft 11. The column 9 extends into the groove and is slidably connected to the driven shaft 11. The groove includes an inclined section 1101 and a vertical section 1102 connected to each other. The vertical section 1102 is parallel to the central axis of the driven shaft 11. The cylinder 6 is provided with a strip-shaped through groove 10 for the column 9 to move.

[0063] When the box girder is placed, as the boss 28 moves downward in the cylinder 6, the column 9 will slide downward along the strip groove 10. When the column 9 slides from the inclined section 1101 into the vertical section 1102, it will slide into the driven shaft 11, thereby causing the driven shaft 11 to rotate, so that the driven shaft 11 drives the extension mechanism to move, thereby increasing the bottom support area of ​​the base 1.

[0064] It should be noted that, as the weight borne by the base 1 increases during the descent of the box girder, in order to ensure the smooth movement of the multiple sets of extension mechanisms, the inclined section 1101 occupies a smaller distance in the axial direction of the driven shaft 11 compared to the vertical section 1102, so as to ensure that the extension movement of the multiple sets of extension mechanisms can be completed in the early stage of contact between the box girder and the supporting plate 5.

[0065] The extension mechanism includes a drive rod 12 fixedly mounted on one end of the driven shaft 11, an extension plate 14 slidably fitted into the bottom of the base 1, and a connecting rod 13 connecting the extension plate 14 and the drive rod 12. One end of the connecting rod 13 is rotatably connected to the extension plate 14, and the other end is rotatably connected to the end of the drive rod 12 away from the driven shaft 11. The extension plate 14 is also provided with a through hole 15 that cooperates with the elastic locking mechanism.

[0066] When the column 9 and the driven shaft 11 are slidably engaged, causing the driven shaft 11 to rotate, the driven shaft 11 will drive the driving rod 12 to deflect. Then, the driving rod 12 can push the extension plate 14 to slide towards the outside of the base 1 through the connecting rod 13, thereby increasing the floor area of ​​the base 1 and improving the stability of the equipment.

[0067] When the equipment needs to be recycled, the elastic locking mechanism releases the locking state of the extension plate 14. Subsequently, the first columnar spring 8 rebounds, causing the support plate 5 to pop out from the groove 4. The column 9 rises and slides again with the driven shaft 11. The driven shaft 11 then rotates again (in the opposite direction to the previous rotation). Therefore, the drive rod 12 can pull the extension plate 14 towards the inside of the base 1 through the connecting rod 13 to slide back to its original position, reducing the footprint and facilitating the transportation of the equipment.

[0068] Please refer to it again. Figure 3 The elastic locking mechanism includes an assembly plate 16 fixedly mounted on the sand box 2, a locking rod 17 slidably mounted on the assembly plate 16, and a second cylindrical spring 20 sleeved around the outer periphery of the locking rod 17.

[0069] The locking rod 17 is adapted to the through hole 15, and a ring 19 is fixedly installed on the locking rod 17. The two ends of the second columnar spring 20 are respectively connected to the ring 19 and the assembly plate 16. One end of the locking rod 17 abuts against the extension plate 14, and the other end is provided with a pull ring 18.

[0070] When the extension plate 14 extends outward toward the base 1, the second columnar spring 20 is initially in a compressed state. Then, after the through hole 15 aligns with the locking rod 17, the second columnar spring 20 will rebound, causing the locking rod 17 to slide downward on the assembly plate 16. The locking rod 17 will then spring into the through hole 15, effectively fixing the extension plate 14 and eliminating the upward elastic force of the first columnar spring 8, which is in a compressed state, during the storage of the box girder.

[0071] Furthermore, when retrieving the equipment, the staff can pull the locking rod 17 upwards using the pull ring 18 until the locking rod 17 is pulled out of the through hole 15, so that the first cylindrical spring 8 can smoothly release its elastic potential energy and cause all components to reset.

[0072] Secondly, to avoid excessive wear between the locking rod 17 and the extension plate 14, a ball bearing can be provided at the end of the locking rod 17 away from the pull ring 18, thereby effectively reducing friction and making the movement of each component smoother.

[0073] Please refer to it again. Figure 5 and Figure 7 The supporting plate 5 has an opening 21. The lateral pressure mechanism includes a horizontal plate 22 slidably disposed within the opening 21. One end of the horizontal plate 22 is fixed with an inclined plate 23, which slidably fits against the base 3. The other end is provided with a pressure assembly. The pressure assembly includes multiple mounting sleeves 24 fixedly installed on the horizontal plate 22 and multiple horizontal columns 25 respectively disposed in the mounting sleeves 24. The horizontal columns 25 are interference-fitted with the mounting sleeves 24, and the ends of the multiple horizontal columns 25 away from the horizontal plate 22 are provided with abutment plates 26.

[0074] Since the pedestal 3 is shaped like a frustum, when the supporting plate 5 moves toward the groove 4, the inclined plate 23 will give way, and the horizontal plate 22 will slide to one side in the opening 21. Correspondingly, the pressing plate 26 will move toward the box girder. The horizontal column 25 and the mounting sleeve 24 are interference-fitted, so that both sides of the box girder are subjected to force, which has a certain positioning effect, making it convenient for the staff to operate the lifting and placement of the box girder and avoiding the box girder from swinging and shifting during the lifting and placement process.

[0075] It should be noted that, since the sides of the box girder are usually inclined, the pressure plate 26 can be rotatably connected to the cross column 25 to ensure that the pressure plate 26 can fit against the side of the box girder and improve the positioning effect.

[0076] Secondly, two recesses 27 are provided at the top of the pedestal 3. The depth of the recesses 27 is the same as the thickness of the horizontal plate 22, to ensure the flatness of the top of the pedestal 3 after the box girder is placed, and to prevent the box girder from tilting during storage.

[0077] As another embodiment of the present invention, an installation method for the reusable adjustable beam storage device is also proposed, comprising the following steps:

[0078] Step 1, foundation treatment: Using the positioning center as a reference, drive piles into the ground at an angle of 40-50°, ensuring that the piles are driven to the same depth and angle in each direction.

[0079] Step 2: Install base 1. The pile body is compacted using a tamping machine. Standard sand dunes are placed, and base 1 is placed on the dunes. The standard sand is adjusted to level the pile body. After leveling, the base is welded and fixed to the pile body.

[0080] Step 3: Install the pedestal 3. Position the pedestal 3 on the base 1 and place it in the center of the base 1. Adjust the height of the pedestal 3 by adjusting the standard sand to make the four pedestals 3 in the same horizontal position, and then place the box girder.

[0081] Step 4: Install the far-infrared alarm system. After the box girder is placed, install the far-infrared alarm system at the center of the bottom of the box girder. The system will emit infrared rays outward from the center, so that the four pedestals 3 are at the same horizontal position.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0083] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
