Description

Technical Field

[0001] This utility model relates to the field of concrete pipe production technology, specifically a concrete pipe surface repair device. Background Technology

[0002] Concrete pipes are widely used in urban and rural sewer systems due to their significant advantages, such as durability and relatively low cost. These pipes are primarily constructed of reinforced steel and concrete, with the steel providing structural strength and the concrete offering protection and support. Because of their high compressive strength, concrete pipes can effectively withstand the pressure of the underground soil and the loads from vehicles and pedestrians on the surface, making them less prone to deformation or cracking. Furthermore, concrete pipes possess excellent durability, allowing them to be used for extended periods underground without significant damage. Simultaneously, the relatively smooth surface of concrete pipes helps reduce water flow resistance and prevents debris accumulation, thus ensuring the smooth operation of the drainage system.

[0003] Currently, concrete pipes are mostly produced through factory prefabrication. After pouring, the surface of concrete pipes often has unevenness, such as localized protrusions, honeycomb-like holes, and surface roughness. If these surface defects are not addressed promptly, moisture and harmful gases will erode the internal channels of the concrete during use, thus reducing the durability of the concrete pipes. Under current technological conditions, the surface of concrete pipes is usually treated manually, but this method is inefficient and yields inconsistent quality. Utility Model Content

[0029] After the precast concrete pipe 3 is poured, its surface may be uneven, such as local protrusions, honeycomb, pitting and other defects. If these defects are not treated in time, moisture and harmful gases will erode the internal channels of the concrete during use, reducing the durability of the concrete pipe 3. This utility model provides a concrete pipe surface repair device to smooth the surface of the concrete pipe 3 and repair these surface defects during production, so as to ensure the quality of the concrete pipe 3 structure.

[0030] like Figures 1-5 As shown in some embodiments, a concrete pipe surface repair device includes a guide rail 1, a conveying plate 2 slidably connected to the guide rail 1, a positioning area for a concrete pipe 3 disposed on the conveying plate 2, and a smoothing mechanism 4. Specifically, the conveying plate 2 moves the poured concrete pipe 3 to the positioning area, and the smoothing mechanism 4 smooths the outer and inner walls of the concrete pipe 3 respectively, thereby improving the flatness and smoothness of the concrete pipe 3 and improving the quality of the concrete pipe 3.

[0031] The smoothing mechanism 4 includes a rotating plate 41, an inner wall smoothing module 42, and an outer wall smoothing module 43. The inner wall smoothing module 42 and the outer wall smoothing module 43 are located at the lower part of the rotating plate 41 to ensure their effective operation. Specifically, the inner wall smoothing module 42 is located inside the outer wall smoothing module 43. This design allows for simultaneous repair of both the inner and outer walls of the concrete pipe 3, improving both the repair quality and efficiency.

[0032] Furthermore, the rotating plate 41 can slide against the bearing plate 8, and the bearing plate 8 is connected to the rotary motor 7. The rotary motor 7 is responsible for driving the rotating plate 41 to rotate, so as to achieve uniform smoothing treatment of the inner and outer walls of the concrete pipe 3.

[0033] Simultaneously, the bearing plate 8 is connected to the hydraulic rod 6, which drives the bearing plate 8 to move precisely. This, in turn, drives the smoothing mechanism 4 to move up and down while performing the smoothing process, achieving continuous smoothing of the concrete pipe 3 from bottom to top. This design enables the repair device to maintain high stability and precision during operation, thereby improving the repair effect.

[0034] In this embodiment, during operation, the poured concrete pipe 3 is placed on the conveying plate 2 and pushed into the working position along the guide rail 1. The hydraulic rod 6 drives the bearing plate 8 to move downward, causing the rotating plate 41 to carry the smoothing mechanism 4 into the pipe. When the rotating plate 41 moves to the specified position, the rotary motor 7 drives the rotating plate 41 to rotate, and the inner wall smoothing module 42 and the outer wall smoothing module 43 rotate synchronously to smooth and repair the inner and outer walls of the pipe. At the same time, the hydraulic rod 6 drives the bearing plate 8 to move upward, completing the repair operation of the entire pipe.

[0035] Furthermore, in some embodiments, the support mechanism 5 is positioned correspondingly to the bottom of the guide rail 1, providing stable support for the spreading mechanism 4. This design allows the device to be more stable when performing surface repair work on the concrete pipe 3, thereby improving the efficiency and quality of the repair work.

[0036] Specifically, the support mechanism 5 includes a first support plate 51 and a second support plate 52, which are connected to each other by a support column 53. A hydraulic rod 6 is fixedly connected to the first support plate 51, allowing the hydraulic rod 6 to stably support the movement of the bearing plate 8. This design makes the device more flexible when performing surface repair work on the concrete pipe 3, thereby improving the efficiency and quality of the repair work.

[0037] The first support plate 51 is specially designed with an avoidance through hole, which corresponds to the position of the rotary motor 7 so that the rotary motor 7 will not be interfered with by the first support plate 51 when it moves upward.

[0038] The second support plate 52 is provided with a limiting through hole. The function of this through hole is to limit the movement range of the outer wall smoothing module 43, ensuring that it can stay on the predetermined path when performing surface repair work on the concrete pipe 3. The outer wall smoothing module 43 passes through this limiting through hole, thereby enabling precise operation during the repair process and ensuring repair quality.

[0039] Furthermore, in some embodiments, the inner wall smoothing module 42 includes a support arm 421 and an inner column 426. The two ends of the inner column 426 are tightly welded to the support arm 421 and the rotating plate 41, respectively, ensuring structural stability. The end of the support arm 421 is fastened to the fixing plate 425 with screws; this connection method ensures the stability and reliability between the support arm 421 and the fixing plate 425. The fixing plate 425 is connected to the first trowel 422 via a damping rod 423 to ensure the stability of the first trowel 422.

[0040] The damping rod 423 is wrapped with a telescopic spring 424. The function of the telescopic spring 424 is to adjust the distance between the first trowel 422 and the inner wall of the concrete pipe 3, so that the first trowel 422 and the inner wall of the concrete pipe 3 are always in close contact, thereby achieving efficient and precise repair work.

[0041] Furthermore, in some embodiments, the outer wall smoothing module 43 includes a positioning ring 431 and an outer column 433. Specifically, the positioning ring 431 is tightly and firmly connected to the lower surface of the rotating plate 41 through the outer column 433, ensuring the stability and reliability of the module.

[0042] Furthermore, the positioning ring 431 is internally designed with a ring array of second trowels 432. The working surfaces of these second trowels 432 are carefully designed as arc-shaped surfaces with variable curvature. This design allows them to effectively conform to the surface of the concrete pipe 3. This adaptability ensures the uniformity and precision of the repair work, thereby achieving a more uniform and precise repair effect and greatly improving the quality and efficiency of the surface repair of the concrete pipe 3.

[0043] Furthermore, in some embodiments, the diameter of the limiting through hole in the second support plate 52 is smaller than the diameter of the rotating plate 41, forming a mechanical limiting structure. This limiting design ensures that the rotating plate 41 maintains a precise position during operation, making the repair work more accurate and efficient.

[0044] Furthermore, in some embodiments, the damping rod 423 and the first trowel 422 are designed as a hinged structure. This unique hinged design allows the first trowel 422 to be adjusted in angle and position as needed, thereby ensuring that the first trowel 422 achieves optimal fit with the inner wall of the concrete pipe 3. This adjustment of fit effectively improves the accuracy and efficiency of the repair work, ensuring that the repair quality of the concrete pipe 3 surface reaches an ideal state. In addition, this hinged structure also allows the first trowel 422 to be fine-tuned during the repair process to address any irregular shapes or damage that may occur on the inner wall of the concrete pipe 3, thereby further improving the repair effect.

[0045] Furthermore, in some embodiments, a slide rail structure is specially designed around the rotating plate 41. This slide rail structure can completely surround the edge of the support plate 8. Through the interaction between the support plate 8 and the slide rail, it plays the role of supporting the support plate 8. This design can not only form a stable support between the support plate 8 and the rotating plate 41, but also allow the rotating plate 41 to rotate relative to the support plate 8, thereby driving the rotation of the entire smoothing mechanism 4.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
