Description

Technical Field

[0001] This invention relates to the field of main reinforcement bar positioning technology for steel cages, specifically a double-layer adjustable main reinforcement bar positioning device for steel cages. Background Technology

[0002] In the field of pile foundation construction in building engineering, the fabrication and installation of steel cages is a crucial step, but traditional techniques have many drawbacks.

[0003] On the one hand, most pile foundations are cylindrical, requiring the use of a formwork to tie the reinforcing bars into the desired shape during the construction of the steel cage. However, traditional arc-shaped formwork has significant drawbacks, failing to effectively position the top main reinforcement bars. During construction, the main reinforcement bars are prone to deviation, requiring construction workers to spend extra time and effort to manually straighten them, which not only increases the difficulty of construction but also reduces construction efficiency.

[0004] On the other hand, for double-layer steel cages, the positions of the inner and outer layers of reinforcing bars need to be strictly controlled. However, the traditional method of manually fabricating in layers and then connecting or vertically binding them makes it difficult to accurately position the relative positions of the inner and outer layers of steel cages during connection, easily leading to eccentricity. This eccentricity results in unreasonable structural stress, fails to guarantee the overall quality of the steel cage, and seriously affects the stability and safety of the pile foundation. Moreover, prefabricating a steel cage in two stages greatly extends the construction period and increases construction costs.

[0005] Furthermore, most existing rebar cage processing equipment is unable to meet the manufacturing requirements of rebar cages of different models and sizes, and it is inconvenient to make size adjustments when faced with rebar cages of different specifications. Manufacturing equipment that matches specific models and sizes would not only consume a lot of time, but also consume excessive material resources.

[0006] Therefore, the purpose of this invention is to provide a double-layer adjustable steel cage main reinforcement positioning device to overcome the shortcomings of the prior art. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a double-layer adjustable steel cage main reinforcement positioning device, which solves the problem that traditional devices cannot effectively position the main reinforcement.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a double-layer adjustable rebar cage main reinforcement positioning device, comprising a slide rail, a base plate fixedly installed on the upper part of the slide rail moving seat, an adjustment mechanism fixedly installed on the upper part of the base plate, the adjustment mechanism comprising a driving component and an adjustment component, used for adjusting the height of the device, a positioning mechanism fixedly connected to the output end of the adjustment mechanism, used for positioning the rebar cage, multiple fixing mechanisms provided outside the positioning mechanism, the fixing mechanisms comprising a sliding component and a connecting component, used for fixing the rebar cage, and a collection mechanism fixedly installed on the upper part of the slide rail, used for collecting metal waste from the construction site.

[0009] Preferably, the drive component in the adjustment mechanism includes a fixing groove fixedly installed on the upper part of the base plate, and a motor is fixedly installed at the bottom of the fixing groove.

[0010] Preferably, the adjustment assembly includes a threaded rod fixedly connected to the output end of a motor, a slide block threadedly connected to the outer side of the threaded rod, a second motor fixedly mounted at one end of the slide block, and a rotating shaft fixedly connected to the output end of the second motor.

[0011] Preferably, the positioning mechanism includes a main rib positioning outer ring, a main rib positioning inner ring inside the main rib positioning outer ring, a fixing ring inside the main rib positioning inner ring, and the main rib positioning outer ring, the main rib positioning inner ring, and the fixing ring are fixed together by a support frame.

[0012] Preferably, the rotating shaft is fixedly connected to the inside of the fixed ring.

[0013] Preferably, the sliding component in the fixing mechanism includes multiple fixed sliders that are slidably installed on the outer side of the main rib positioning outer ring and the outer side of the main rib positioning inner ring. Each of the multiple fixed sliders has a bolt at one end and a fixing frame fixedly installed at one end.

[0014] Preferably, the connecting assembly includes cylindrical main rib connectors that are fixedly installed on the upper part of multiple fixing frames. Each of the cylindrical main rib connectors has a cylindrical sleeve on its outer wall, and one side of each cylindrical sleeve is fixed by two bolts.

[0015] Preferably, lighting lamps are provided on both sides of the upper part of the base plate.

[0016] Preferably, the method includes a collection box fixedly installed on the upper part of the slide rail, an electric push rod fixedly installed on one side inside the collection box, a push plate fixedly connected to the output end of the electric push rod, a plurality of scrapers provided at the bottom of the push plate, a rotating rod rotatably connected to the outer side of the scrapers, a stop door fixedly installed at the bottom of the rotating rod, a connecting plate fixedly installed on one side of the slide rail, a collection box fixedly connected to one end of the connecting plate, and a feed hopper provided on the upper part of the collection box.

[0017] Preferably, a scale is provided on one side of the outer ring of the main rib positioning, and the graduation accuracy of the angle scale value on one side of the outer ring of the main rib positioning is ±0.5°.

[0018] This invention provides a double-layer adjustable rebar cage main reinforcement positioning device. It has the following beneficial effects:

[0019] 1. This invention adjusts the position of the device by moving the sliding rail seat. Motor 1 drives the threaded rod to make the sliding seat move the positioning mechanism to adjust the height. Motor 2 drives the rotating shaft to make the positioning mechanism rotate. It can accurately match the fabrication requirements of rebar cages in different construction scenarios. In construction sites of different heights or for rebar cages of different sizes, this device can be quickly adjusted to the appropriate position and angle without complicated reinstallation or modification processes, which greatly saves construction preparation time, effectively improves construction efficiency, and can adapt to diverse construction environments, thus enhancing the practicality of the device.

[0020] 2. This invention uses a support frame for stable connection, and the outer ring of the main reinforcement positioning is marked with a graduation accuracy of ±0.5°. Construction personnel calculate the distribution angle of the main reinforcement according to the graduation and design drawings, and use a sliding fixed slider, a cylindrical main reinforcement connector and a cylindrical clamp to accurately adjust the position of the main reinforcement and the diameter of the steel cage. This achieves high-precision positioning of the main reinforcement of the steel cage, ensuring uniform distribution of the main reinforcement, effectively avoiding problems such as main reinforcement offset and uneven spacing in traditional methods, improving the manufacturing quality of the steel cage, and thus ensuring the structural stability and safety of the pile foundation project.

[0021] 3. This invention allows the fixed slider to slide outside the outer ring and inner ring of the main reinforcement positioning. The cylindrical main reinforcement connector is connected to the fixing frame by bolts, and components adapted to different main reinforcement diameters can be replaced. This detachable and adjustable design enables the device to easily handle the fabrication of rebar cages with different pile diameters, main reinforcement diameters, and main reinforcement quantities. In actual construction, there is no need to customize special equipment for different specifications of rebar cages, reducing equipment procurement and maintenance costs. At the same time, it improves the versatility of the equipment. Construction units can flexibly adjust the device parameters and quickly switch the specifications of rebar cage fabrication, improving the flexibility and efficiency of construction.

[0022] 4. This invention uses an electric push rod to move a push plate, and a scraper 704 at the bottom of the push plate to gather waste. When the push plate moves to the position of the rotating rod, the waste will exert a pushing force on the gate, thereby pushing the rotating rod to rotate and opening the gate. Finally, the waste falls into the collection box through the feed hopper, thus collecting the waste and keeping the construction site clean. Attached Figure Description

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.

[0035] Please see the appendix Figure 1 - Appendix Figure 10This invention provides a double-layer adjustable rebar cage main reinforcement positioning device, including a slide rail 1, a base plate 2 fixedly installed on the upper part of the slide rail 1 movable seat, an adjustment mechanism 3 fixedly installed on the upper part of the base plate 2, the adjustment mechanism 3 including a drive component and an adjustment component, which is used to adjust the height of the device, a positioning mechanism 4 fixedly connected to the output end of the adjustment mechanism 3, which is used to position the rebar cage, a plurality of fixing mechanisms 5 are provided outside the positioning mechanism 4, the fixing mechanism 5 including a sliding component and a connecting component, which is used to fix the rebar cage, and a collection mechanism 7 fixedly installed on the upper part of the slide rail 1, which is used to collect metal waste from the construction site.

[0036] The drive component in the adjustment mechanism 3 includes a fixing groove 301 fixedly installed on the upper part of the base plate 2, and a motor 302 is fixedly installed at the bottom of the fixing groove 301.

[0037] Specifically, the drive assembly in the adjustment mechanism 3 includes a fixing groove 301 fixedly mounted on the upper part of the base plate 2. The fixing groove 301 provides installation space and support structure for other components of the drive assembly, and a motor 302 is fixedly mounted at its bottom. The motor 302 can provide stable and controllable power output, providing power support for subsequent adjustment actions.

[0038] The adjustment assembly includes a threaded rod 303 fixedly connected to the output end of motor 1 302, a slide 304 threadedly connected to the outer side of the threaded rod 303, a motor 2 305 fixedly mounted on one end of the slide 304, and a rotating shaft 306 fixedly connected to the output end of motor 2 305.

[0039] Specifically, the adjustment component includes a threaded rod 303 fixedly connected to the output end of motor 302. When motor 302 starts running, it drives the threaded rod 303 to rotate synchronously. A slide 304 is threadedly connected to the outer side of the threaded rod 303. As the threaded rod 303 rotates, the slide 304 moves up and down along the thread of the threaded rod 303. Motor 305 is fixedly mounted on one end of the slide 304, and a rotating shaft 306 is fixedly connected to the output end of motor 305. Motor 305 can drive the rotating shaft 306 to rotate, thereby realizing the angle adjustment of the positioning mechanism 4, enabling the positioning mechanism 4 to better adapt to different construction needs and improving the flexibility and adaptability of the device.

[0040] The positioning mechanism 4 includes a main rib positioning outer ring 401, a main rib positioning inner ring 402 inside the main rib positioning outer ring 401, a fixing ring 403 inside the main rib positioning inner ring 402, and a support frame 404 fixing the inner sides of the main rib positioning outer ring 401, the main rib positioning inner ring 402 and the fixing ring 403.

[0041] Specifically, the positioning mechanism 4 includes a main reinforcement positioning outer ring 401, inside which is a main reinforcement positioning inner ring 402. The main reinforcement positioning inner ring 402 and the main reinforcement positioning outer ring 401 together position the main reinforcement of the steel cage. A fixing ring 403 is also provided inside the main reinforcement positioning inner ring 402. The main reinforcement positioning outer ring 401, the main reinforcement positioning inner ring 402, and the fixing ring 403 are fixedly connected by a support frame 404. The support frame 404 enhances the overall structural stability of the positioning mechanism 4, ensuring that all positioning components can work together during the steel cage fabrication process, guaranteeing the accuracy of the main reinforcement positioning.

[0042] The rotating shaft 306 is internally fixedly connected to the retaining ring 403;

[0043] Specifically, the rotating shaft 306 is internally fixedly connected to the fixed ring 403, so that the motor 305 can directly drive the fixed ring 403 to rotate through the rotating shaft 306, thereby driving the entire positioning mechanism 4 to adjust the angle. The positioning mechanism 4 can adjust the angle more flexibly, providing precise positioning support for the fabrication of steel cages with different angle requirements.

[0044] The sliding component in the fixing mechanism 5 includes multiple fixed sliders 501 that are slidably installed on the outer side of the main rib positioning outer ring 401 and the main rib positioning inner ring 402. Each of the multiple fixed sliders 501 has a bolt 502 at one end and a fixing bracket 503 fixedly installed at one end.

[0045] Specifically, the sliding components in the fixing mechanism 5 include multiple fixed sliders 501 that are slidably mounted on the outer side of the main reinforcement positioning outer ring 401 and the inner side of the main reinforcement positioning inner ring 402. These fixed sliders 501 can slide along specific tracks on the outer side of the main reinforcement positioning outer ring 401 and the inner side of the main reinforcement positioning inner ring 402, facilitating flexible adjustment according to the design position of the main reinforcement in the steel cage. Each of the multiple fixed sliders 501 has a bolt 502 at one end, which secures the slider 501 in the required position, ensuring no displacement during the steel cage fabrication process. Each of the multiple fixed sliders 501 also has a fixing bracket 503 fixedly mounted on one end, providing a connection base for the subsequent installation of the cylindrical main reinforcement connector 504.

[0046] The connecting assembly includes cylindrical main rib connectors 504 that are fixedly installed on the upper part of multiple fixing frames 503. Each cylindrical main rib connector 504 has a cylindrical sleeve 505 on its outer wall. One side of each cylindrical sleeve 505 is fixed by bolt 2 506.

[0047] Specifically, the connecting components include cylindrical main rib connectors 504, all fixedly mounted on the upper part of multiple fixing frames 503. Each cylindrical main rib connector 504 has a cylindrical sleeve 505 on its outer wall, which provides fixation and protection for the main rib. One side of each cylindrical sleeve 505 is fixed by a bolt 506. By tightening or loosening the bolt 506, the degree of fixation of the cylindrical sleeve 505 to the main rib can be easily adjusted, ensuring the stability of the main rib during manufacturing.

[0048] Lighting lamps 6 are installed on both sides of the upper part of the base plate 2;

[0049] Specifically, lighting lamps 6 are installed on both sides of the upper part of the base plate 2. At the construction site for the fabrication of the reinforcing cage, the lighting conditions may be complex. The lighting lamps 6 installed on both sides of the upper part of the base plate 2 can provide sufficient lighting for the construction process, making it easier for construction personnel to operate accurately, improving the accuracy and safety of the construction, and reducing operational errors caused by insufficient light.

[0050] The collection mechanism 7 includes a collection box 701 fixedly installed on the upper part of the slide rail 1. An electric push rod 702 is fixedly installed on one side inside the collection box 701. A push plate 703 is fixedly connected to the output end of the electric push rod 702. Multiple scrapers 704 are provided at the bottom of the push plate 703. A rotating rod 705 is rotatably connected to the outer side of the scraper 704. A stop door 706 is fixedly installed at the bottom of the rotating rod 705. A connecting plate 700 is fixedly installed on one side of the slide rail 1. A collection box 707 is fixedly connected to one end of the connecting plate 707. A feed hopper 708 is provided on the upper part of the collection box 707.

[0051] Specifically, the collection mechanism 7 includes a collection box 701 fixedly installed on the upper part of the slide rail 1, which is used for temporary storage of metal waste generated during construction, such as welding spatter and steel rebar fragments. An electric push rod 702 is fixedly installed on one side inside the collection box 701. The output end of the electric push rod 702 is fixedly connected to a push plate 703. When the electric push rod 702 is energized, it drives the push plate 703 to perform horizontal reciprocating motion within the collection box 701, pushing the accumulated waste towards the outlet. Multiple scrapers 704 are evenly arranged on the bottom of the push plate 703. The scrapers 704 are made of wear-resistant rubber, and their bottoms are tightly fitted to the inner bottom surface of the collection box 701. During the movement of the push plate 703, the scrapers 704 can thoroughly scrape up the waste adhering to the bottom of the box, preventing waste residue. The outer side of the scraper 704 is rotatably connected to the rotating rod 705 via a pin. A stop 706 is fixedly installed at the bottom of the rotating rod 705. Under normal conditions, the stop 706 hangs vertically downward under the action of gravity, closing the discharge port of the collection box 701 to prevent waste from falling in accidentally. When the push plate 703 pushes the waste to the discharge port, the waste squeezes the stop 706, thereby pushing the rotating rod 705 to rotate, and the stop 706 opens, allowing the waste to be discharged. A connecting plate 700 is fixedly installed on one side of the slide rail 1 via bolts. The other end of the connecting plate 700 is fixedly connected to the collection box 707. A feed hopper 708 is provided on the upper part of the collection box 707. The feed hopper 708 facilitates the smooth falling of waste into the collection box 707, realizing the centralized collection and management of waste and keeping the construction site clean.

[0052] The outer ring 401 of the main reinforcement positioning ring has a scale on one side, and the graduation accuracy of the angle scale value on one side of the outer ring 401 of the main reinforcement positioning ring is ±0.5°.

[0053] Specifically, a scale is provided on one side of the outer ring 401 for positioning the main reinforcement bars. These scales provide construction personnel with a clear reference standard. Based on the quantity and distribution requirements of the main reinforcement bars in the design drawings, construction personnel can accurately determine the installation positions of the fixed slider 501 and the cylindrical main reinforcement bar connector 504 using these scales, thereby achieving precise adjustment of the circumferential spacing of the main reinforcement bars. The graduation accuracy of the angle scale value on one side of the outer ring 401 for positioning the main reinforcement bars is ±0.5°, enabling the positioning device to meet higher construction standards. Construction personnel can more precisely control the angular position of the main reinforcement bars, effectively avoiding problems such as uneven spacing or angular deviations, greatly improving the accuracy of the main reinforcement bar positioning in the steel cage, and ensuring the fabrication quality of the steel cage.

[0054] Working principle: First, the movable seat of slide rail 1 adjusts the overall position of the device, facilitating flexible layout in different construction scenarios. Motor 1 302 drives the threaded rod 303 to rotate, and the slide 304, which is threadedly connected to the threaded rod 303, moves up and down along the threaded rod 303, thereby driving the positioning mechanism 4 to adjust its height to adapt to the fabrication of rebar cages with different height requirements. At the same time, motor 2 305 on the slide 304 drives the rotating shaft 306 to rotate, allowing the positioning mechanism 4 to rotate at a certain angle for precise positioning.

[0055] The outer ring 401 and inner ring 402 of the main reinforcement positioning mechanism 4, as well as the internal fixing ring 403, are securely connected by a support frame 404. One side of the outer ring 401 is marked with a graduation accuracy of ±0.5°. Construction personnel use this graduation to calculate the distribution angle of each main reinforcement bar on the circular positioning steel ring based on the number of main reinforcement bars in the steel cage shown in the design drawings. Multiple slidable fixing sliders 501 are installed on the outer sides of the outer ring 401 and inner ring 402. One end of each fixing slider 501 is equipped with a bolt 502, which secures it in the desired position. A fixing frame 503 is fixedly installed at the other end.

[0056] The cylindrical main reinforcement connector 504 is installed on the upper part of the fixing frame 503, and its outer wall is provided with a cylindrical sleeve 505, which is fixed by bolt 506. According to the design diameter of the reinforcing cage, the construction personnel slide the cylindrical main reinforcement connector 504 to change the distance between it and the circular steel ring. After adjustment, the bolt 506 is tightened to determine the diameter of the reinforcing cage. Furthermore, a suitable main reinforcement connector can be selected according to the diameter of the main reinforcement and installed onto the cylindrical sleeve 505 to achieve compatibility with main reinforcements of different diameters.

[0057] After preparation, insert both ends of the main reinforcing bars of the steel cage into the corresponding cylindrical main reinforcing bar connectors 504. Each main reinforcing bar is connected and fixed by two cylindrical main reinforcing bar connectors 504 to ensure that the main reinforcing bars are accurately positioned in both the circumferential and axial directions without any offset or shaking. At this time, if the lighting at the construction site is poor, the lighting lights 6 on both sides of the upper part of the base plate 2 can be turned on to provide sufficient lighting for construction.

[0058] Metal scrap generated during construction falls into the collection box 701 on the upper part of the slide rail 1. The electric push rod 702 inside the collection box 701 drives the push plate 703 to move. The scraper 704 at the bottom of the push plate 703 gathers the scrap. When the push plate 703 moves to the position of the rotating rod 705, the scrap will push the stop door 706, thereby pushing the rotating rod 705 to rotate, which in turn opens the stop door 706. Finally, the scrap falls into the collection box 707 through the feed hopper 708, realizing the collection of scrap and keeping the construction site clean.

[0059] Throughout the process, the coordinated action of various parts of the device enables precise positioning and efficient fabrication of the main reinforcement bars of the steel cage, reduces the construction steps of double-layer steel cages, improves construction efficiency, and is applicable to the fabrication of steel cages with different pile diameters, main reinforcement diameters, and main reinforcement quantities. It also ensures the cleanliness of the construction site and has strong versatility and practicality.
