Description

Technical Field

[0001] This utility model belongs to the technical field of rebar placement equipment, specifically a coiled rebar placement device. Background Technology

[0002] Coiled steel bars are a type of threaded steel bar, named for the spiral transverse ribs on their surface that are coiled in a disc shape. They are produced by rolling steel into ribbed steel bars with spiral transverse ribs using a wire rod mill, and then coiling them into a disc shape. Their tensile strength is significantly higher than that of ordinary steel bars, and they can withstand greater loads. They are suitable for high-load-bearing structures such as bridges and high-rise buildings.

[0003] Due to the circular, coiled nature of reinforcing bars, they require specialized equipment for orderly storage and convenient retrieval. Among these, the wire-laying frame is the core operating equipment, directly affecting the smoothness and accuracy of reinforcing bar laying during construction.

[0004] Through long-term observation, it has been found that existing coiled steel bars, when placed on a wire-laying frame, may not be centered due to the different inner diameters of the coiled steel bars and the lack of a support structure for the inner diameter of the coiled steel bars on the wire-laying frame. Subsequently, when the coiled steel bars are rotated, the output direction of the outer ring of the steel bars will change with the rotation angle, which is prone to causing large swaying and has a certain impact on construction efficiency. Therefore, a coiled steel bar placement device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a coiled steel bar placement device.

A limiting slide shaft is fixedly connected to the inner wall of the extrusion plate, and the limiting slide shaft is slidably connected to the support frame. A push plate is fixedly connected to the end of the limiting slide shaft for fixing the coiled rebar after it is sleeved.

A connecting rod is fixedly connected to the end of the connector. The connecting rod is slidably connected to the extrusion plate.

[0007] Preferably, the limiting frame is L-shaped, and multiple fixing plates are fixed to the bottom of the placement tray. A strong spring is fixed to the top of the fixing plate, and a movable plate is fixed to the top of the strong spring. A sliding block is fixed to the side wall of the movable plate to buffer the placed coiled steel bars. The sliding block is slidably connected to the side wall of the limiting frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, the device includes a base 1, a placement tray 11 rotatably connected to the center of the base 1, multiple limiting brackets 12 fixed to the top of the placement tray 11, and limiting rings 13 fixed to the side walls of the placement tray 11. A fixed platform 14 is fixed to the inner walls of the multiple limiting brackets 12. A self-locking electric actuator 15 and a storage battery are installed at the bottom of the fixed platform 14. The storage battery powers the self-locking electric actuator 15. Multiple support brackets 16 are fixed to the top of the fixed platform 14. A sliding frame 17 is fixed to the top of the support brackets 16. The sliding frame 17 is fixedly connected to the top of the fixed platform 14. A pressing plate 18 is slidably connected to the inner wall of the sliding frame 17. The extrusion plate 18 is designed with an inclined structure. A limiting slide shaft 19 is fixedly connected to the inner wall of the extrusion plate 18, and the limiting slide shaft 19 is slidably connected to the support frame 16. A push plate 110 is fixedly connected to the end of the limiting slide shaft 19 for fixing the coiled rebar after it has been fitted. The output end of the self-locking electric actuator 15 is slidably positioned inside the fixing platform 14. A connector 111 is fixedly connected to the output end of the self-locking electric actuator 15, and a connecting rod 112 is fixedly connected to the end of the connector 111. The connecting rod 112 is slidably connected to the extrusion plate 18. The coiled rebar is fitted onto the placement plate 11, and multiple limiting frames 12 initially limit the circumference of the coiled rebar. Positioning is adjusted to prevent significant lateral displacement of the reinforcing bar on the placement tray 11; simultaneously, the limiting ring 13 further blocks the coiled reinforcing bar from the side wall of the placement tray 11 to prevent it from slipping off the edge of the placement tray 11. The self-locking electric actuator 15 at the bottom of the fixing platform 14 is activated, and the energy storage battery provides power to the self-locking electric actuator 15. The output end of the self-locking electric actuator 15 slides downward inside the fixing platform 14, driving the fixed connecting piece 111 to move. The connecting piece 111 then drives the connecting rod 112 to move. Since the connecting rod 112 is slidably connected to the extrusion plate 18, and the extrusion plate 18 is slidably connected to the support frame 16 via the limiting sliding shaft 19, the extrusion plate 18 will... The sliding plate 18 slides along the inner wall of the sliding frame 17. The inclined structure of the extrusion plate 18 moves it closer to the coiled rebar, eventually causing the push plate 110 at the end of the limiting sliding shaft 19 to contact the coiled rebar. During the contact process, the position of the coiled rebar is corrected, thus achieving the fixed clamping of the coiled rebar after it is installed. This step is achieved by automatic clamping with the help of the self-locking electric push rod 15, which allows the coiled rebar to be placed in the center. This reduces the problem that the output direction of the outer ring rebar will change with the rotation angle when the coiled rebar is rotated, which is prone to large shaking. This improves the efficiency of the coiled rebar construction, and at the same time improves the fixing efficiency and the accuracy of the clamping force.

[0026] like Figure 1-5As shown, the limiting frame 12 is L-shaped. Multiple fixing plates 2 are fixed to the bottom of the placement tray 11. A strong spring 21 is fixed to the top of the fixing plate 2. A movable plate 22 is fixed to the top of the strong spring 21. A sliding block 23 is fixed to the side wall of the movable plate 22 to buffer the placed coiled steel bar. The sliding block 23 is slidably connected to the side wall of the limiting frame 12. During the process of placing the coiled steel bar onto the placement tray 11, the coiled steel bar will first contact the movable plate 22 and exert downward pressure on it. When the movable plate 22 is subjected to pressure, it moves downwards, simultaneously compressing the strong spring 21 fixed to its bottom. During this process, the sliding block 23 on the side wall of the movable plate 22 slides along the side wall of the limiting frame 12, providing guidance for the up-and-down movement of the movable plate 22 and preventing it from deviating. After the coiled steel bar is placed stably, the strong spring 21 generates an upward reaction force under its own elasticity, forming a buffer support for the coiled steel bar through the movable plate 22. This step, with the cooperation of the strong spring 21 and the movable plate 22, can effectively buffer the impact force when the coiled steel bar is placed, preventing the coiled steel bar from deforming or being damaged due to direct impact with the placement plate 11, thus protecting the appearance and performance of the coiled steel bar. The sliding cooperation between the sliding block 23 and the limiting frame 12 provides stable guidance for the movable plate 22, ensuring that the movable plate 22 moves only in the vertical direction, preventing it from tilting or deviating during the buffering process, and improving the reliability of the buffer structure.

[0027] like Figure 1-5 As shown, a guide plate 3 is fixedly connected at the included angle of the limiting frame 12. One side wall of the guide plate 3 is inclined. An installation groove 31 is opened in the middle of the guide plate 3. Several rotating wheels 32 are rotatably connected to the inclined surface of the guide plate 3. During the process of putting the coiled steel bar into the placement plate 11, the coiled steel bar will first contact the guide plate 3 at the included angle of the limiting frame 12. Because one side wall of the guide plate 3 is inclined, and several rotating wheels 32 are rotatably connected to its inclined surface, the coiled steel bar will slide along the inclined surface of the guide plate 3 under its own weight or external force, and drive the rotating wheels 32 to rotate. Under the rolling action of the rotating wheels 32, the coiled steel bar can slide more smoothly into the designated position between the limiting frame 12 and the placement plate 11. This step, with the inclined structure of the guide plate 3 and the rolling action of the rotating wheels 32, can guide the coiled steel bar to enter the designated placement position quickly and smoothly, reduce the jamming phenomenon of the coiled steel bar during the installation process, reduce the operation difficulty and labor intensity of the operator, and the rolling of the rotating wheels 32 replaces the sliding friction between the coiled steel bar and the guide plate 3, greatly reducing the wear between the two and extending the service life of the guide plate 3 and the coiled steel bar.

[0028] like Figure 1-5As shown, a support rod 4 is fixedly connected to the top of the connector 111, and a baffle plate 41 is fixedly connected to the top of the support rod 4 for blocking external dust. With the baffle plate 41 unfolded, impurities generated during the installation of the coiled steel bar can be blocked. This step, under the action of the baffle plate 41, can effectively prevent external pollutants such as dust and rainwater from contacting the top of the extrusion plate 18, and improve the stability of the subsequent contact and sliding between the connecting rod 112 and the extrusion plate 18.

[0029] like Figure 1-5 As shown, two reinforcing ribs 5 are fixedly connected at the connection between the limiting slide shaft 19 and the push plate 110. A push block 51 is fixedly connected to the outer wall of the push plate 110. The push block 51 is arc-shaped on the side near the coiled rebar. When the limiting slide shaft 19 drives the push plate 110 to clamp and fix the coiled rebar, the two reinforcing ribs 5 at the connection between the limiting slide shaft 19 and the push plate 110 can enhance the structural strength of the connection between the two, and prevent the connection between the limiting slide shaft 19 and the push plate 110 from breaking or deforming due to excessive clamping force. At the same time, the push block 51 on the outer wall of the push plate 110 contacts the coiled rebar. Since the push block 51 is arc-shaped on the side near the coiled rebar, it can better fit with the arc surface of the coiled rebar and increase the contact area.

[0030] like Figure 1-5 As shown, rubber pads are fixedly connected to the top of the two movable plates 22. When the coiled steel bar is placed on the movable plate 22, the rubber pads on the top of the movable plate 22 directly contact the coiled steel bar. The rubber pads have a certain elasticity and friction. During the placement of the coiled steel bar, they can further buffer the impact force of the coiled steel bar on the movable plate 22, and at the same time increase the friction force between the coiled steel bar and the movable plate 22.

[0031] Working principle: By placing the coiled steel bar onto the placement plate 11, multiple limiting brackets 12 initially limit the circumferential position of the coiled steel bar, preventing it from shifting significantly laterally on the placement plate 11. Simultaneously, limiting rings 13 further block the coiled steel bar from the side wall of the placement plate 11, preventing it from slipping off the edge of the placement plate 11. This activates the self-locking electric actuator 15 at the bottom of the fixing platform 14. The energy storage battery provides power to the self-locking electric actuator 15, causing its output end to slide downwards inside the fixing platform 14, driving the fixed connector 111 to move. The connector 111 then drives the connecting rod 1... 12. During the movement, since the connecting rod 112 is slidably connected to the extrusion plate 18, and the extrusion plate 18 is slidably connected to the support frame 16 through the limiting slide shaft 19, the extrusion plate 18 will slide on the inner wall of the sliding frame 17. The inclined structure of the extrusion plate 18 makes it move closer to the coiled steel bar, and finally drive the push plate 110 at the end of the limiting slide shaft 19 to contact the coiled steel bar. During the contact process, the position of the coiled steel bar can be corrected, and the coiled steel bar can be fixed and clamped after being sleeved. During the process of placing the coiled steel bar on the placement plate 11, the coiled steel bar will first contact the movable plate 22 and exert downward pressure on it. When the movable plate 22 is subjected to pressure, it moves downward and compresses the strong spring 21 fixed at its bottom. During this process, the sliding block 23 on the side wall of the movable plate 22 slides along the side wall of the limiting frame 12, providing guidance for the up and down movement of the movable plate 22 and preventing it from deviating. When the coiled steel bar is placed stably, the strong spring 21 generates an upward reaction force under its own elasticity, which forms a buffer support for the coiled steel bar through the movable plate 22. During the process of putting the coiled steel bar into the placement plate 11, the coiled steel bar will first contact the guide plate 3 at the angle of the limiting frame 12. Because one side wall of the guide plate 3 is inclined, and several rotating wheels 32 are rotatably connected to its inclined surface, the coiled steel bar will slide along the inclined surface of the guide plate 3 under its own weight or external force, and drive the rotating wheels 32 to rotate. Under the rolling action of the rotating wheels 32, the coiled steel bar can slide more smoothly into the designated position between the limiting frame 12 and the placement plate 11. With the unfolded shielding plate 41, the impurities generated during the installation of the coiled steel bar can be shielded. When the limiting sliding shaft 19 drives the push plate 110 to clamp and fix the coiled steel bar, the two reinforcing ribs 5 at the connection between the limiting sliding shaft 19 and the push plate 110 can enhance the structural strength of the connection between the two. At the same time, the push block 51 on the outer wall of the push plate 110 contacts the coiled steel bar. Since the push block 51 is set in an arc shape on the side close to the coiled steel bar, it can better fit the arc surface of the coiled steel bar. When the coiled steel bar is placed on the movable plate 22, the rubber pad on the top of the movable plate 22 directly contacts the coiled steel bar.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
