Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pole production, and particularly relates to a device for removing cement paste and plasticity of a tapered concrete pole. BACKGROUND

[0002] The tapered high-performance concrete pole (concrete pole) is a key load-bearing component in the modern power transmission and distribution network, and the production thereof generally adopts a centrifugal forming process. Due to the inherent geometric characteristics of the tapered structure, the centrifugal force acting on the large end region is much greater than that acting on the small end region in the high-speed rotation process, resulting in excessive migration and enrichment of the cement paste (especially water) in the concrete mixture to the inner wall of the large end under the action of the centrifugal force gradient, and forming a layer of excess cement paste or high water-cement ratio thin paste. This phenomenon destroys the uniformity of the wall thickness of the concrete pole and the material density, directly affecting the mechanical properties and durability of the product, and is the main process bottleneck restricting the quality improvement of the tapered high-performance concrete pole.

[0003] At present, there is a lack of mature automatic solutions for the large-end paste enrichment problem in the industry, and manual intervention is generally relied on. The operator needs to hold a tool and insert it into the mold rotating at high speed or low speed to scrape and clean during the operation of the centrifuge or during intermittent shutdown. This manual intervention method has the following significant defects: first, close-range operation in the running state of the equipment poses serious safety risks such as paste splashing and mechanical entrapment, and the hidden danger is prominent; second, the timing, force, and path of manual cleaning are all based on experience, and it is difficult to accurately control, resulting in inconsistent cleaning effect and affecting the uniformity of product quality; finally, the production process needs to be frequently stopped for manual operation, which seriously disrupts the continuity of production and restricts the operation efficiency of the automatic production line, increasing the production cost.

[0029] Embodiment 2

[0030] Please refer to Figure 7 With Figure 8 , the second embodiment of the application, which is based on the previous embodiment.

[0031] Specifically, the cleaning mechanism 6 includes a cleaning rod 61 fixedly connected to one side of the clamp 5, a mounting groove 62 opened in the surface of the cleaning rod 61, a mounting plate 63 arranged in the inner cavity of the mounting groove 62, a profiling scraper 64 fixedly connected to one side of the mounting plate 63, mounting holes 65 opened in the surfaces of the cleaning rod 61 and the mounting plate 63, and mounting bolts 66 arranged in the inner cavities of the mounting holes 65. The cleaning rod 61 is made of high-strength stainless steel. The profiling scraper 64 includes a base body 641, a flexible buffer layer 642, and a wear-resistant layer 643. The flexible buffer layer 642 is arranged on the surface of the base body 641, and the wear-resistant layer 643 is arranged on the surface of the flexible buffer layer 642. The flexible buffer layer 642 is provided with a pressure sensor 10 on one side. The base body 641 is made of aluminum alloy. The flexible buffer layer 642 is made of rubber material. The wear-resistant layer 643 is made of polyurethane composite material.

[0032] The profiling scraper 64 is controlled by the program to gradually match the wear-resistant layer 643 with the conical surface of the inner wall of the large end of the mold through the linkage interpolation movement in the X and Y directions. The pressure sensor 10 feeds back the contact pressure between the scraper and the inner wall in real time to prevent damage to the equipment or secondary damage to the inner wall of the concrete rod caused by excessive resistance. The control system drives the feeding mechanism 4 to make the profiling scraper 64 perform scraping work along the inner wall surface under the condition of maintaining appropriate contact pressure. In this process, the enriched cement slurry is scraped off efficiently, and the inner wall is plasticized and trimmed. The cleaning rod 61 made of high-strength stainless steel ensures that it has sufficient rigidity and straightness as a cantilever structure when bearing the mud resistance, centrifugal vibration and other loads, and can always maintain a stable motion trajectory. The installation groove 62 and the installation bolt 66 realize quick disassembly and assembly of the profiling scraper 64, reduce maintenance costs, and can adapt to different taper and diameter of the inner wall curve of the concrete rod. The base 641 made of aluminum alloy is light in weight and high in strength, and is used to support the entire profiling scraper 64. The flexible buffer layer 642 made of rubber material is used to buffer the contact force between the scraper and the inner wall of the concrete rod, adapt to the slight concave-convex of the inner wall of the concrete rod (such as mold joint traces), and ensure the fit of the scraper and the inner wall. The wear-resistant layer 643 made of polyurethane composite material has wear resistance and self-lubricity, can effectively scrape off the dry hard mud (such as cement slurry or high-sand-content thin slurry) on the inner wall of the concrete rod, and at the same time avoid scratching the inner wall of the concrete rod. The three work together to realize the functions of flexible fitting and efficient mud removal.

[0033] Example 3

[0034] Please refer to Figure 6 , the third embodiment of the present application, which is based on the previous two embodiments.

[0035] Specifically, the collecting mechanism 7 includes a first guide plate 71 arranged in the inner cavity of the mud shield 3, a discharging hole 72 opened at the bottom of the first guide plate 71, a second guide plate 73 arranged at the bottom of the first guide plate 71, a collecting hole 74 opened on the front of the mud shield 3, a through slot 8 opened on the left side of the mud shield 3, a circular slot 9 opened on the right side of the mud shield 3, the clamp 5 is a three-jaw chuck, and the centrifugal workbench 1 is externally connected with a power shaft.

[0036] The scraped mud splashes under the centrifugal force and is effectively blocked by the mud shield 3. The splashes hit the first inclined guide plate 71 and then flow downward and collect. The splashes drop through the lower hole 72 of the first inclined guide plate 71 to the second guide plate 73, change the flow direction, and finally flow into the collection hole 74 in the front of the mud shield 3. The splashes are collected by the vacuum suction system and then removed for treatment, so as to avoid the pollution of the equipment and the environment by the mud and keep the working environment clean. After the work is completed, the feeding mechanism 4 moves reversely in sequence to withdraw the cleaning mechanism 6 from the mold. The centrifugal process can seamlessly connect to the next stage (such as high-speed finishing), so as to realize the on-line cleaning and finishing without stopping and full automation. The through slot 8 provides a channel for the extension of the cleaning rod 61, and the circular slot 9 is used for installation and cooperation with the concrete rod mold 2 to enhance the sealing performance and functionality of the overall structure. The three-jaw chuck can stably clamp the cleaning rod 61 with different diameters. The power shaft drives the four supporting wheels (prior art, rubber wheel) on the centrifugal workbench 1 to rotate. The supporting wheels drive the concrete rod mold 2 to rotate at high speed through the driving ring (prior art) on the surface of the concrete rod mold 2, and then drive the concrete rod mold 2 to perform the centrifugal work.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered by the scope of the claims of the present application.
