Description

Technical Field

[0001] This utility model belongs to the technical field of concrete surface treatment equipment, and in particular relates to a floating smoothing assembly with a finishing function. Background Technology

[0002] In the construction of large-scale infrastructure such as wind power generation, the wind turbine tower is a key component, and the quality of its precast concrete segments directly affects the structural performance and service life of the entire tower. The smoothness and finish of the concrete segment surface are important indicators of its quality, affecting not only the tower's appearance but also its wind resistance, corrosion resistance, and other properties. Therefore, high-quality smoothing and finishing of the concrete segment surface is crucial.

[0003] Traditional methods of surface treatment for concrete tunnel segments primarily rely on manual labor. Workers use trowels and polishing tools to repeatedly scrape and smooth the concrete surface. This method has several drawbacks. First, manual labor is labor-intensive and inefficient, making it difficult to meet the demands of large-scale production. Prolonged, high-intensity work can easily lead to worker fatigue, resulting in inconsistent work quality and varying troweling and polishing results. Second, manual operation makes it difficult to guarantee the uniformity and consistency of troweling and polishing. Differences in the techniques and pressure applied by different workers make it difficult to achieve the required smoothness and finish on the concrete tunnel segment surface.

[0004] With the development of automation technology, some automatic leveling equipment has emerged in the market. However, existing automatic leveling equipment has significant shortcomings when processing precast concrete segments for wind turbine towers. Some equipment lacks an effective floating structure and cannot adaptively adjust to the unevenness of the concrete segment surface, resulting in poor leveling effects and prone to localized inadequate or excessive leveling. Moreover, most of these devices only have a single leveling function and lack a finishing mechanism, making it impossible to further finish the leveled concrete surface. This leaves the concrete surface still rough and uneven, affecting the quality of the segments.

[0005] Therefore, developing a floating smoothing assembly with a finishing function is of significant practical importance. This floating smoothing assembly with a finishing function can solve the problems existing in the current technology, improve the quality and efficiency of surface smoothing and finishing operations for concrete tunnel segments, and meet the production needs of precast concrete tunnel segments for wind power generation towers.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0042] In the field of precast concrete segment production for wind power towers, this utility model provides a floating smoothing assembly with a finishing function to improve the efficiency and quality of segment surface smoothing operations. The core innovation of this automatic smoothing machine focuses on mechanical structure design, achieving efficient and precise processing of segment surface smoothing operations through a series of ingenious concepts and optimizations.

[0043] Please see Figure 1 and Figure 2 A floating smoothing assembly 5 with light-gathering function adopts the following innovative technical solution:

[0044] The floating smoothing assembly is mounted on the frame uprights 11 of the frame beam 1 at both ends, and includes a smoothing machine frame beam 51, which is arranged parallel to the length of the frame beam 1. Contouring support wheels 32 are fixedly mounted on both ends of the smoothing machine frame beam 51 to abut against the outer circumferential walls of the contouring rings at both ends of the precast formwork of the wind turbine tower, providing radial positioning and ensuring the accuracy of the smoothing operation. A linear guide assembly 510, preferably a non-powered linear guide assembly, allows the smoothing machine frame beam 51 to slide freely in the vertical direction relative to the frame uprights, achieving overall lifting and floating to adapt to concrete segment surfaces of different heights. A transverse screw 52 is mounted parallel to the smoothing machine frame beam 51, with one end connected to a drive motor 521, providing drive for the horizontal movement of the smoothing head 54 along the length of the smoothing machine frame beam 51. The transverse slider 53 is mounted on the transverse lead screw 52 and is used to move horizontally along the trowel beam 51 under the drive of the transverse lead screw 52. The trowel head 54 is connected to the transverse slider 53 and is used to smooth the surface of the concrete pipe segment. The trowel head 54 is connected to the transverse drag chain 56, which is mainly used for the orderly storage and guidance of various pipelines and lines.

[0045] To ensure the stability of the lateral movement, a horizontal linear guide rail assembly 57 is also provided.

[0046] The smoothing head 54 includes a horizontal carriage base 541 connected to a transverse slider 53; a lifting mechanism 542 connected to the upper end of the horizontal carriage base 541, the lifting mechanism 542 including a lifting base 5421 fixedly connected to the upper end of the horizontal carriage base 541, and a lifting drive cylinder 5422 fixedly installed on the upper surface of the lifting base 5421; a vertical carriage base 5423 connected to the piston rod of the lifting drive cylinder 5422; a vertical linear guide rail assembly 5424 installed between the vertical carriage base 5423 and the horizontal carriage base 541; a smoothing motor 543 vertically installed inside the vertical carriage base 5423; the output end of the smoothing motor 543 connected to the grinding disc 544, and the vertical carriage base 5423 is raised and lowered by the lifting drive cylinder 5422, thereby adjusting the height of the grinding disc 544 to meet the smoothing operation requirements at different heights.

[0047] Working principle: The drive motor 21 drives the drive sprocket 22 to rotate, and the drive sprocket 22 meshes with the chain 23, thereby driving the trowel to move along the precast formwork of the wind turbine tower. At the same time, the floating trowel assembly 5 can be raised and lowered according to the height change of the concrete segment surface. The transverse screw 52 in the floating trowel assembly 5 drives the transverse slider 53 to move the trowel head 54 horizontally, and the lifting mechanism 542 adjusts the height of the grinding disc 544 to realize the troweling operation on the surface of the concrete segment.

[0048] Technical effect: This embodiment has a simple structure. The smoothing machine is driven by the meshing of the sprocket and the chain. The floating smoothing assembly can adapt to the smoothing needs of concrete pipe segments of different heights, ensuring the basic function of smoothing operation is realized.

[0049] To further meet the finishing requirements of the smoothed concrete surface, this application mainly relates to a finishing mechanism 6 of a floating smoothing assembly with a finishing function, connected to both sides of the smoothing head 54, used to finish the concrete surface after smoothing by the smoothing head 54. The finishing mechanism 6 includes a connecting bracket 61, fixedly connected to the smoothing head 54; a finishing scraper 62; a hinged connecting rod assembly 63, connecting the finishing scraper 62 and the connecting bracket 61, allowing the finishing scraper 62 to rotate around a horizontal axis; and an angle adjustment drive cylinder 64, hinged between the connecting bracket 61 and the hinged connecting rod assembly 63, used to adjust and lock the angle of the finishing scraper 62 relative to the connecting bracket 61. The finishing scraper 62 is used to finish the concrete surface after smoothing by the grinding disc 544, and the angle of the finishing scraper 62 can be adjusted by the angle adjustment drive cylinder 64 to adapt to different finishing requirements.

[0050] Working Principle: After the smoothing head 54 completes the smoothing operation, or simultaneously with smoothing, a finishing operation is performed. The angle adjustment drive cylinder 64 drives the hinged connecting rod assembly 63 to move, thereby adjusting the angle of the finishing scraper 62 relative to the connecting bracket 61, so that the finishing scraper 62 can perform the finishing operation on the smoothed concrete surface at a suitable angle. The addition of the finishing mechanism meets the finishing requirements of the smoothed concrete surface. The angle adjustment drive cylinder can flexibly adjust the angle of the finishing scraper to adapt to different finishing requirements, further improving the quality of the concrete surface.

[0051] Please see Figures 1 to 13 The following is a detailed description of an automatic surface smoothing machine for precast concrete segments of wind power towers, featuring a floating smoothing assembly with a smoothing function.

[0052] The automatic troweling machine mainly consists of a frame beam 1, a walking drive device 2, a walking wheel set 3, a floating troweling assembly 5, and key functional units such as a control box and an electrical box. These mechanical components work together to complete the troweling task on the surface of the concrete pipe segments. The frame beam 1 provides a stable support structure for the entire equipment; the walking drive device 2, in conjunction with the walking wheel set 3, allows the equipment to move flexibly on the precast mold 7; in this embodiment, the walking drive device 2 includes a drive motor 21, which is mounted on the frame upright plate 11; a drive sprocket 22 is mounted on the output end of the drive motor 21; a chain 23 is laid on the arc-shaped outer side of the wind turbine tower precast mold, and the drive sprocket 22 meshes with the chain 23. The drive motor 21 drives the drive sprocket 22 to rotate, and the meshing relationship between the drive sprocket 22 and the chain 23 drives the troweling machine to move along the mold frame; the aforementioned floating troweling assembly 5 directly acts on the surface of the pipe segments to achieve the troweling operation.

[0053] To further improve the adaptability of the troweling machine to concrete segments with different curvatures,

[0054] Please see Figures 7 to 10 It also includes a grinding disc swing mechanism 55, which is hinged in the vertical slide seat 5423, and a smoothing motor 543 is mounted on the grinding disc swing mechanism 55. The grinding disc oscillation mechanism 55 includes a left swing arm 551 and a right swing arm 552 fixedly mounted on a vertical slide seat 5423 in the vertical direction, and a smoothing motor is fixedly connected to it. The active swing arm 553 and the driven swing arm 554 are hinged in the vertical slide seat 5423 through a support shaft. The active swing arm 553 extends vertically upward to the upper end of the left swing arm 551 and the right swing arm 552. An active swing rod 5531 is provided in the vertical direction at the upper end of the active swing arm 553. The active swing rod 5531 is inserted into the elongated oval hinge hole of the hinge joint 555. The hinge joint 555 includes a T-shaped joint 5551 and a U-shaped joint 5552. The other end of the T-shaped joint 5551 is connected to the left swing drive cylinder 556, which is fixedly mounted on the left swing arm 551. The other end of the U-shaped joint 5552 is connected to the right swing drive cylinder 557, which is fixedly mounted on the right swing arm 552. Driven by the left swing drive cylinder 556 and the right swing drive cylinder 557, the active swing arm 553 and the driven swing arm 554 swing, which in turn drives the smoothing motor 543 and the grinding disc 544 to swing, so as to adapt to the smoothing operation of concrete pipe segments with different curvatures.

[0055] Working principle: The left swing drive cylinder 556 and the right swing drive cylinder 557 drive the active swing arm 553 and the driven swing arm 554 to swing, which in turn drives the smoothing motor 543 and the grinding disc 544 to swing. This allows the grinding disc 544 to better adapt to the surface of concrete segments with different curvatures, thereby achieving more precise smoothing operations. The addition of the grinding disc swing mechanism greatly improves the smoothing machine's adaptability to concrete segment surfaces with different curvatures, making the smoothing operation more precise and efficient, and improving the smoothing quality.
