Description

Technical Field

[0001] This utility model relates to the field of roll welding equipment technology, and more specifically, to a roll welding device for prestressed concrete pipe pile skeleton. Background Technology

[0002] Prestressed concrete pipe piles are widely used in foundation engineering fields such as building construction, bridge construction, and port terminals due to their advantages of high strength, high durability, and convenient construction. As the core load-bearing component of the pipe pile, the processing quality of the pipe pile skeleton directly affects the overall bearing capacity and service life of the pipe pile. Roll welding is a key step in the formation of the pipe pile skeleton, which requires precise and firm welding of the longitudinal reinforcement and the spiral reinforcement after the spiral reinforcement is wrapped around the outside of the longitudinal reinforcement.

[0003] Existing pipe pile skeleton rolling welding devices have many shortcomings in practical applications. On the one hand, the stability of the wire laying mechanism of some devices is not good, and the wire laying speed of the spiral reinforcement is difficult to match with the rotation speed of the longitudinal reinforcement of the pipe pile skeleton. This can easily lead to uneven winding of the spiral reinforcement and excessive tension fluctuation, which in turn can cause problems such as incomplete welding, missed welding or weld cracking at the welding joint. On the other hand, the lack of an effective limiting and guiding structure during the longitudinal reinforcement transportation process makes the longitudinal reinforcement prone to displacement and misalignment during welding, affecting the coaxiality and structural regularity of the skeleton.

[0004] To address the aforementioned issues, a prestressed concrete pipe pile skeleton rolling welding device is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, a prestressed concrete pipe pile skeleton rolling welding device is provided.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions:

[0007] This utility model provides a prestressed concrete pipe pile skeleton rolling welding device, including: a transport frame, a base arranged on the side of the transport frame, a take-up frame fixedly installed on the top of the base, a take-up wheel rotatably installed on the side of the take-up frame facing the transport frame, the take-up wheel including a cylinder and discs located at both ends of the cylinder, two auxiliary rods symmetrically fixedly installed on the bottom of the take-up frame, two auxiliary wheels rotatably installed on each auxiliary rod, the two auxiliary wheels respectively rolling contact with the two discs of the take-up wheel, a gear ring fixedly installed on the side of the take-up wheel facing the transport frame, a motor fixedly installed on the take-up frame, a gear fixedly installed on the output end of the motor, the gear meshing with the gear ring.

[0008] Furthermore, a guide frame and a connecting platform are fixedly installed on the transport frame. The guide frame is hollow inside. The connecting platform is located on the side of the guide frame. An installation plate is fixedly installed on the side of the connecting platform facing the base. A welding wheel is fixedly installed on the side of the installation plate facing the base. A guide plate is fixedly installed on the transport frame. Multiple conveying holes are evenly opened on the installation plate and the guide plate, and each conveying hole on the installation plate and the guide plate corresponds to the other.

[0009] Furthermore, a limit rod is fixedly installed on the side of the guide frame near the base, and a limit ring is installed at the end of the limit rod.

[0010] Furthermore, a linear module is fixedly installed on the base, a slide is slidably installed on the linear module, and a fixed plate is fixedly installed on the slide. The fixed plate is located inside the take-up reel, and the end face of the fixed plate is flush with the end face of the toothed ring. Multiple combination holes are evenly opened in the circumferential direction on the fixed plate. Each combination hole includes an insertion hole and a limiting hole. The insertion hole is a round hole, and the limiting hole is an arc-shaped hole. The insertion hole and the limiting hole are connected. The insertion hole is located at one end of the limiting hole, and the diameter of the insertion hole is larger than the width of the limiting hole.

[0011] Furthermore, multiple casters are fixedly installed on the bottom of the base.

[0012] Based on the above, the beneficial effects of the prestressed concrete pipe pile skeleton welding device of this utility model are:

[0013] By driving the gear and gear ring of the motor to mesh, the take-up reel rotates precisely. With the support and limit of the auxiliary rod and auxiliary wheel on the take-up reel, the spiral reinforcement's wire feeding speed and rotation speed are precisely matched. This effectively avoids the problem of uneven winding of the spiral reinforcement due to tension fluctuations. At the same time, the stable wire feeding rhythm reduces the probability of false welding, missing welding and weld cracking during the welding process, significantly improving the firmness and consistency of the weld seam of the pipe pile skeleton and ensuring the overall bearing capacity of the pipe pile.

[0014] The limiting rod and limiting ring on one side of the guide frame can guide the spiral reinforcement. The evenly distributed conveying holes in the middle of the guide plate and the installation plate can guide the longitudinal reinforcement to be accurately conveyed along the preset trajectory, ensuring that the longitudinal reinforcement always maintains a regular arrangement, effectively improving the coaxiality and structural regularity of the pipe pile skeleton, avoiding the problem of uneven stress on the skeleton caused by misalignment of the longitudinal reinforcement, and helping to extend the service life of the pipe pile.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-4 As shown, a prestressed concrete pipe pile skeleton welding device provided in this embodiment will be described in detail below:

[0022] A prestressed concrete pipe pile frame welding device, such as Figures 1-4As shown, the device includes: a transport frame 1, a base 8 on the side of the transport frame 1, a take-up frame 7 fixedly mounted on the top of the base 8, and a take-up reel 6 rotatably mounted on the side of the take-up frame 7 facing the transport frame 1. The take-up reel 6 is used to hold the spiral reinforcement. The take-up reel 6 has an I-shaped cross-section, including a cylinder and discs at both ends of the cylinder. The diameter of the discs is larger than the diameter of the cylinder. The spiral reinforcement is coiled and sleeved on the outer surface of the cylinder of the take-up reel 6. Two auxiliary rods 9 are symmetrically fixedly mounted on the bottom of the take-up frame 7. Two auxiliary wheels 10 are rotatably mounted on each auxiliary rod 9. The two auxiliary wheels 10 are in rolling contact with the two discs of the take-up reel 6, and when the take-up reel 6 rotates, it drives the auxiliary wheels 10 to rotate. A gear ring 17 is fixedly mounted on the side of the take-up reel 6 facing the transport frame 1. A motor 15 is fixedly mounted on the take-up frame 7. A gear 16 is fixedly mounted on the output end of the motor 15, and the gear 16 meshes with the gear ring 17. When motor 15 starts, the output of motor 15 drives gear 16 to rotate. Since gear 16 meshes with gear ring 17, the rotation of gear 16 drives gear ring 17 to rotate, and the rotation of gear ring 17 drives take-up reel 6 to rotate. At the same time, the rotation of gear ring 17 also drives the auxiliary wheels 10 on both sides to rotate synchronously. The auxiliary wheels 10 support and limit the take-up reel 6 to prevent it from deviating when rotating. At the same time, by adjusting the speed of motor 15, the wire feeding speed of take-up reel 6 can be precisely controlled to ensure that the spiral wire feeding rhythm matches the subsequent welding requirements.

[0023] like Figures 1-4 As shown, a guide frame 4 and a connecting platform 14 are fixedly installed on the transport frame 1. The guide frame 4 is hollow inside. The connecting platform 14 is located beside the guide frame 4. An installation plate 5 is fixedly installed on the side of the connecting platform 14 facing the base 8. A welding wheel 12 is fixedly installed on the side of the installation plate 5 facing the base 8. A guide plate 3 is fixedly installed on the transport frame 1. Multiple conveying holes are evenly opened on the installation plate 5 and the guide plate 3, and each conveying hole on the installation plate 5 corresponds to one on the guide plate 3. While the spiral reinforcement is being laid out, the longitudinal reinforcement enters the device through the conveying holes of the guide plate 3. The guide plate 3 provides initial guidance for the longitudinal reinforcement. Subsequently, the longitudinal reinforcement passes through the interior of the guide frame 4 and then through the conveying holes of the installation plate 5, so that the multiple longitudinal reinforcements are always evenly distributed and coaxially arranged. When both the spiral reinforcement and the longitudinal reinforcement reach the welding area beside the welding wheel 12, the welding wheel 12 can quickly heat up and evenly transfer the heat to the welding contact point to weld the welding area of ​​the spiral reinforcement and the longitudinal reinforcement. At the same time, the take-up wheel 6 rotates slowly, so that the spiral reinforcement is evenly wrapped around the outside of the longitudinal reinforcement. Under the continuous heating action of the welding wheel 12, the contact point of the spiral reinforcement and the longitudinal reinforcement melts and the welding is completed, forming a solid pipe pile skeleton structure.

[0024] A limiting rod 13 is fixedly installed on the side of the guide frame 4 near the base 8. A limiting ring 131 is installed at the end of the limiting rod 13. During the roll welding operation, the end of the spiral rib will pass through the limiting ring 131 and be fixed on one of the longitudinal ribs. The limiting ring 131 is used to position and guide the end of the spiral rib.

[0025] A straight-line module 20 is fixedly mounted on the base 8. A slide table 21 is slidably mounted on the straight-line module 20. A fixed plate 22 is fixedly mounted on the slide table 21. The inside of the take-up reel 6 is hollow. The fixed plate 22 is located inside the take-up reel 6, and the end face of the fixed plate 22 is flush with the end face of the toothed ring 17. Multiple combination holes are evenly opened in a circumferential direction on the fixed plate 22. Each combination hole includes an insertion hole 23 and a limiting hole 24. The insertion hole 23 is a round hole, and the limiting hole 24 is an arc-shaped hole. The insertion hole 23 communicates with the limiting hole 24. The insertion hole 23 is located at one end of the limiting hole 24, and the diameter of the insertion hole 23 is larger than the width of the limiting hole 24. The ends of the longitudinal reinforcement bars are shaped like discs, with a diameter larger than that of the longitudinal reinforcement bars. The diameter of the insertion hole 23 is larger than that of the disc head. The diameter of the limiting hole 24 is equal to that of the longitudinal reinforcement bars but smaller than that of the disc head. The limiting hole 24 and the longitudinal reinforcement bars form a clearance fit, allowing the longitudinal reinforcement bars to be inserted into the limiting hole 24. The diameter of the conveying hole is larger than that of the disc head.

[0026] The bottom of the base 8 is fixedly equipped with multiple casters 11. If the position of the base 8 needs to be adjusted to adapt to different production stations, the base 8 can be moved by pushing the casters 11 at the bottom of the base 8, flexibly adjusting the layout of the device to meet the needs of diverse production scenarios.

[0027] The working principle of this embodiment is as follows:

[0028] First, the spiral reinforcement is wound onto the take-up reel 6. At the same time, the ends of multiple longitudinal reinforcements with the tops are passed through the conveying holes in the middle of the guide plate 3 and the mounting plate 5 respectively, ensuring that the longitudinal reinforcements are arranged along the preset trajectory. The tops of the longitudinal reinforcements are inserted into the insertion holes 23, and then the tops are slid into the limiting holes 24, so that the limiting holes 24 lock the longitudinal reinforcements, thereby fixing the ends of the longitudinal reinforcements.

[0029] Then, the end of the spiral reinforcement is passed through the limiting ring 131, and the end of the spiral reinforcement is fixed to one of the longitudinal reinforcements. Afterwards, the connection status of each component is checked, the initial preparation work is completed, the main power supply of the device is turned on, the motor 15 starts, and the output end of the motor 15 drives the gear 16 to rotate. Since the gear 16 meshes with the toothed ring 17 on one side of the take-up reel 6, the rotation of the gear 16 drives the toothed ring 17 to rotate, and the rotation of the toothed ring 17 drives the take-up reel 6 to rotate. At the same time, the rotation of the toothed ring 17 also drives the auxiliary wheels 10 on both sides to rotate synchronously. The rotation of the take-up reel 6 drives the spiral reinforcement wound on it to rotate synchronously. At the same time, the linear module 20 starts, driving the slide table 21 to move away from the transport frame 1, thereby driving the fixed plate 22 to move synchronously. The movement of the fixed plate 22 drives the longitudinal reinforcement to move synchronously. During the movement of the longitudinal reinforcement, the spiral reinforcement will spirally wrap around the longitudinal reinforcement, and under the action of the welding wheel 12, the spiral reinforcement is welded and fixed to the longitudinal reinforcement, completing the roll welding of the prestressed concrete pipe pile skeleton.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
