Description

Technical Field

[0001] This utility model relates to the field of smoothing technology, specifically to an automated smoothing structure. Background Technology

[0002] Concrete pipe piles are slender, precast hollow cylindrical components made of reinforced concrete or prestressed concrete. They are widely used in foundation construction for buildings, bridges, ports, and other engineering projects. Reaching lengths of tens of meters, they possess high strength, high density, low permeability, and impact resistance. During manufacturing, centrifugal molding is employed, combined with prestressing technology to enhance crack resistance and bending stiffness, effectively preventing damage during transportation and construction. Construction methods include hammer driving and static pressure driving. The resulting piles are of reliable quality, with fast construction speeds, significantly shortening the construction period. Their bearing capacity is higher than that of driven pipe piles or bored piles of the same diameter, making them particularly suitable for geological conditions such as soft soil, silt, sand, and weathered rock. Furthermore, concrete pipe piles have a wide range of design options, are convenient to hoist and transport, have simple construction sites, and facilitate easy monitoring of pile quality. However, they require strict control measures during transportation and storage, especially in saturated cohesive soil sites, and are not suitable for complex geological conditions such as soil layers containing large amounts of boulders, hard strata, or limestone.

[0003] In existing technologies, concrete smoothing work mostly relies on manual operation. On the one hand, manual smoothing is inefficient, which can significantly extend the project cycle and increase time costs in large-scale construction scenarios. On the other hand, due to the variability of manual operation, it is difficult to ensure the consistency of smoothing quality, and problems such as uneven surface and uneven thickness are easy to occur, affecting the aesthetics and performance of the structure. Therefore, we need an automated smoothing structure. Utility Model Content

[0008] Preferably, the fixed frame forms a rotating structure with the rotating frame via a drive motor, and the output end of the drive motor is fixed to the rotating frame via a reducer.

[0009] Preferably, the buffer assembly includes a device frame, which is fixed to the bottom of the rotating frame. A guide rod is fixedly connected inside the device frame, and a spring is sleeved on the guide rod. A slide is sleeved on the outer wall of the guide rod, and the slide is fixed to one end of the spring. A movable rod is hinged to one side of the slide, and a buffer plate is hinged to the other end of the movable rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problem in existing technologies where trowels are difficult to adapt to different sizes of drainage pipes during concrete drainage pipe installation, resulting in poor troweling effects and low efficiency, this application implements a structure including a bidirectional motor, a bidirectional screw, and a movable seat. This structure enables automatic adjustment of the distance between the trowels on both sides according to the size of the concrete drainage pipe. Activating the bidirectional motor drives the bidirectional screw to rotate, causing the movable seat to slide along the slide rail, precisely adjusting the distance between the trowels and ensuring that the trowels fit tightly against the drainage pipe. This design improves the adaptability and accuracy of troweling operations, reduces the tediousness of manual adjustments, enhances construction efficiency and quality, and ensures the flatness and stability of the drainage pipe installation. 2. To address the problem in existing technologies where the trowel lacks an effective buffering mechanism during concrete drainage pipe smoothing operations, easily leading to surface damage or equipment failure due to excessive pressure, this application addresses this issue by installing a drive motor to rotate the frame and trowel for smoothing. Simultaneously, a buffering system is constructed using support rods, buffer plates, movable rods, slides, and springs. During smoothing, when the trowel encounters resistance, it pushes the support rods, causing the buffer plates and movable rods to compress the springs in the slides, achieving dynamic buffering. This design effectively absorbs the impact force during smoothing, protecting the surface quality of the drainage pipe, extending equipment lifespan, and ensuring stable and efficient smoothing operations, thereby improving the overall safety and reliability of the construction process.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides an automated smoothing structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the assembly includes a mounting frame 1. A hydraulic cylinder 2 is fixedly connected to the top of the mounting frame 1. A movable plate 3 is fixedly connected to the output end of the hydraulic cylinder 2. A limit rod 4 is fixedly connected to the top of the movable plate 3. One end of the limit rod 4 slides through the mounting frame 1. A smoothing component 5 is provided at the bottom of the movable plate 3. A buffer component 6 is provided on one side of the smoothing component 5. A smoothing knife 7 is connected to the buffer component 6. The smoothing component 5 includes a fixed frame 501, which is fixedly connected to the movable plate 3. A drive motor 502 is fixedly connected inside the fixed frame 501. A rotating frame 503 is fixedly connected to the output end of the drive motor 502. A bidirectional motor 504 is fixedly connected inside the rotating frame 503. A bidirectional screw 505 is fixedly connected to the output end of the bidirectional motor 504. The two ends of the bidirectional screw 505 have opposite thread directions and are respectively threaded to... A movable base 506 is provided, on which a threaded sleeve 507 is fixedly connected. The threaded sleeve 507 is threadedly engaged with a bidirectional screw 505. A sliding sleeve 508 is fixedly connected to the top of the movable base 506. The sliding sleeve 508 is slidably connected to a slide rail 509, which is fixedly connected to a fixed frame 501. By placing the concrete drainage pipe inside the mounting frame 1, the bidirectional motor 504 can be started according to the size of the concrete drainage pipe. The bidirectional motor 504 can drive the bidirectional screw 505 to rotate, allowing the bidirectional screw 505 to rotate within the threaded sleeve 507 inside the movable base 506. The movable base 506 can slide along the outer wall of the slide rail 509 using the sliding sleeve 508, thereby adjusting the spacing between the two trowels 7 on both sides, so that the trowels 7 can fit the concrete drainage pipe.

[0018] Further, such as Figure 3 and Figure 4As shown, the bidirectional motor 504 forms a threaded transmission structure with the bidirectional screw 505 and the threaded sleeve 507. The outer diameter of the bidirectional screw 505 matches the inner diameter of the threaded sleeve 507. The outer wall of the bidirectional screw 505 is tightly fitted with the inner wall of the threaded sleeve 507, which enhances the connection between the bidirectional motor 504 and the bidirectional screw 505. This allows the bidirectional motor 504 to drive the bidirectional screw 505 to rotate inside the threaded sleeve 507, which facilitates the adjustment of the spacing between the smoothing blades 7 on both sides.

[0019] Further, such as Figure 3 and Figure 4 As shown, the movable seat 506 forms a sliding structure with the slide sleeve 508 and the slide rail 509. The inner diameter of the slide sleeve 508 matches the outer diameter of the slide rail 509. The outer wall of the slide rail 509 is tightly fitted with the inner wall of the slide sleeve 508, which strengthens the connection between the slide sleeve 508 and the slide rail 509, allowing the movable seat 506 to slide along the outer wall of the slide rail 509 by relying on the slide sleeve 508.

[0020] Further, such as Figure 3 and Figure 4 As shown, the fixed frame 501 forms a rotating structure with the rotating frame 503 through the drive motor 502, and the output end of the drive motor 502 is fixed to the rotating frame 503 through the reducer, which strengthens the connection effect between the drive motor 502 and the rotating frame 503, so that the drive motor 502 can drive the rotating frame 503 to rotate with the support of the fixed frame 501.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the buffer assembly 6 includes a device frame 601, which is fixed to the bottom of the rotating frame 503. A guide rod 602 is fixedly connected inside the device frame 601, and a spring 603 is sleeved on the guide rod 602. A slide block 604 is sleeved on the outer wall of the guide rod 602, and the slide block 604 is fixed to one end of the spring 603. A movable rod 605 is hinged to one side of the slide block 604, and a buffer plate 606 is hinged to the other end of the movable rod 605. A support rod 607 is fixedly connected to one side of the buffer plate 606, and a smoothing knife 7 is fixedly connected to one end of the support rod 607. The smoothing knife 7 is activated by... The drive motor 502 can drive the rotating frame 503 to rotate, which in turn drives the trowel 7 to smooth the surface of the concrete drainage pipe. In addition, during the smoothing process, the trowel 7 pushes the support rod 607, which in turn drives the buffer plate 606 to move. The buffer plate 606 can then drive the movable rod 605 to move the slide 604, which in turn compresses and buffers the spring 603, thereby achieving the buffering of the trowel 7.

[0022] Further, such as Figure 4 As shown, the equipment frame 601 forms a sliding structure with the slide block 604 through the guide rod 602, and the outer diameter of the guide rod 602 matches the inner diameter of the slide block 604. The outer wall of the guide rod 602 is fitted to the inner wall of the slide block 604, which strengthens the connection between the equipment frame 601 and the guide rod 602, allowing the slide block 604 to move along the equipment frame 601 by relying on the guide rod 602.

[0023] Further, such as Figure 4 As shown, the equipment frame 601 forms an elastic structure with the slide 604 via the spring 603, and the spring 603 is located between the equipment frame 601 and the slide 604, which strengthens the connection between the spring 603 and the equipment frame 601, so that the spring 603 can support and buffer the slide 604 with the support of the equipment frame 601.

[0024] Further, such as Figure 4 As shown, the slide 604 forms a buffer structure with the buffer plate 606 through the movable rod 605, and the movable rod 605 is located between the slide 604 and the buffer plate 606, which strengthens the connection between the slide 604 and the movable rod 605, so that the slide 604 can support the buffer plate 606 by relying on the movable rod 605.

[0025] Working principle: During use, the concrete drainage pipe is placed inside the mounting bracket 1. The bidirectional motor 504 is then started according to the size of the concrete drainage pipe, causing the bidirectional motor 504 to drive the bidirectional screw 505 to rotate. The bidirectional screw 505 rotates within the threaded sleeve 507 of the moving seat 506, allowing the moving seat 506 to slide along the outer wall of the slide rail 509 using the sliding sleeve 508. This allows adjustment of the distance between the two trowels 7, ensuring the trowels 7 fit snugly against the concrete drainage pipe. Furthermore, [the following text is incomplete and requires further context: "in addition..."] By starting the drive motor 502, the drive motor 502 can drive the rotating frame 503 to rotate, which in turn drives the trowel 7 to smooth the surface of the concrete drainage pipe. In addition, during the smoothing process, the trowel 7 pushes the support rod 607, which in turn drives the buffer plate 606 to move. The buffer plate 606 can then drive the movable rod 605 to move the slide 604, which in turn compresses and buffers the spring 603, thereby achieving the buffering of the trowel 7.
