Description

Technical Field

[0001] This application relates to the field of civil engineering construction technology, and in particular to a device for a secondary finishing process of concrete. Background Technology

[0002] With the rapid development of infrastructure construction, concrete, as a core material in building engineering, directly impacts the service life and safety of projects through its construction quality. In the concrete construction process, secondary finishing is a crucial step in improving surface smoothness and density, playing a vital role in preventing surface cracks and enhancing wear resistance. Especially in projects with stringent requirements for concrete surface quality, such as roads, bridges, and large factories, the efficiency and precision of the secondary finishing process are increasingly becoming decisive factors in project quality.

[0003] A search revealed Chinese patent publication number CN212025827U: A concrete leveling device for construction, comprising a base, a first groove on one side of the base, and a first slider slidably connected to the first groove. A rotary motor is installed on one side of the base, and a stud penetrating into the first groove is connected to the output end of the rotary motor. A mounting plate is fixed to one end of the first slider, and a second groove is provided at one end of the mounting plate. A second slider is slidably connected inside the second groove. This invention, through the cooperation of the partition plate and the placement groove, allows excess concrete to enter the top of the leveling plate during leveling, preventing concrete from falling back onto the road surface, thus greatly improving the leveling effect. The cooperation of the insert post and the fixing plate, along with the adjustment of the relative distance between the insert post and the connecting post under the action of a return spring, facilitates the disassembly of the leveling plate and greatly simplifies the usage steps.

[0004] The aforementioned patent specification mentions that "by setting up a plug and a fixing plate to cooperate with each other, and under the action of a return spring, it is easy to adjust the relative distance between the plug and the connecting column, thereby facilitating the disassembly of the flat plate and greatly simplifying the usage steps." The above content can facilitate the disassembly of the flat plate, but it is not comprehensive for flattening and it is difficult to ensure the consistency of the troweling pressure and frequency, which often leads to uneven density of the concrete surface and excessive porosity in some areas, reducing the durability of the concrete. Therefore, a secondary concrete finishing process device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a secondary finishing process device for concrete, which aims to improve the problem of unstable construction quality in some devices.

[0006] The concrete secondary finishing process device provided in this application adopts the following technical solution:

[0007] A secondary concrete finishing process device includes a support column, a scraping assembly inside the support column, a folding mechanism at the top of the support column, a telescopic hollow column fixedly connected to the outside of the folding mechanism, a finishing mechanism outside the telescopic hollow column, a housing fixedly connected to the outside of the finishing mechanism, the finishing mechanism including a pulley, the pulley being slidably connected to the outside of the telescopic hollow column, a rotating shaft fixedly connected to the middle of the pulley, a pulley fixedly connected to the outside of the housing, a retaining ring fixedly connected to the outside of the pulley, a telescopic assembly outside the retaining ring, an adjusting assembly inside the housing, and a motor fixedly connected to the outside of the housing.

[0008] The above technical solution involves the following steps: First, the support column is placed at the edge of the concrete area to be finished. Then, the telescopic hollow column is unfolded to a horizontal working position using the corner support block of the folding mechanism, bevel gear one, bevel gear two, and rotating connecting block. Next, the locking groove of the telescopic component is adjusted to engage with the hollow telescopic column core, fixing the position of the finishing mechanism. Then, motor one is started to drive the rotating shaft, causing the pulley to roll along the telescopic hollow column, moving the finishing mechanism laterally. Simultaneously, motor two drives the finishing plate to swing or rotate via a transmission link to finish the concrete. The adjustment component can adjust the amplitude and frequency of the finishing plate's movement as needed. After finishing, the sliding ring is pushed, moving sliding column two inside the support column, causing the scraping component to descend and level the concrete surface. This device, through the coordinated operation of its various structures, achieves full automation of the secondary concrete finishing process, from preparation and finishing to leveling. Compared to traditional manual operation, it significantly improves construction efficiency, ensures uniform flatness and density of the concrete surface, and effectively reduces subsequent quality problems.

[0009] Preferably, the folding mechanism includes a corner support block, the bottom of which is fixedly connected to the top of the support column, and telescopic hollow columns are rotatably connected to both outer ends of the corner support block.

[0010] By adopting the above technical solution, the support column is positioned in the concrete area to be finished with grout. At this time, the telescopic hollow column is in a folded state. The core component of the folding mechanism, the corner support block, is fixed at the bottom of the support column, serving as a fulcrum for rotation. Through an internal transmission structure, the outer ends of the corner support block are driven to rotate, causing the telescopic hollow column to unfold around the connection point to a horizontal working position. During this process, the stable connection and flexible rotation characteristics of the corner support block ensure that the telescopic hollow column can be quickly and accurately unfolded into place and remain stable after unfolding, providing a reliable foundation for the subsequent installation and operation of the grout finishing mechanism. The design of the folding mechanism effectively solves the problems of device transportation and operation conversion. When the device is idle or relocated, the telescopic hollow column can be folded and folded up, reducing the overall size of the device and facilitating transportation; during operation, it can be quickly unfolded, significantly improving the efficiency of construction preparation, while ensuring the stability and reliability of the grout finishing operation.

[0011] Preferably, the telescopic component includes a toothed groove, the inner groove of which is engaged with the outer side of the toothed ring, the outer side of which is formed on the outer side of the telescopic hollow column, and a hollow telescopic core is slidably connected inside the telescopic hollow column.

[0012] By adopting the above technical solution, the telescopic components are first adjusted according to the required width of the construction area. The hollow telescopic column core is pushed to slide inside the telescopic hollow column, causing the locking groove and locking ring to separate. At this point, the length of the telescopic hollow column can be freely adjusted to adapt to different construction ranges. After adjusting to the appropriate length, the hollow telescopic column core is pushed in the opposite direction, causing the internal locking groove and locking ring to re-engage, thus firmly fixing the grout collection mechanism to the telescopic hollow column. This achieves rapid adjustment and reliable fixation of the telescopic hollow column length, not only enhancing the adaptability of the device to different construction scenarios but also ensuring that the grout collection mechanism will not shift due to vibration or other factors during operation, guaranteeing the stability and accuracy of the grout collection operation.

[0013] Preferably, the adjustment assembly includes a second motor, the second motor is externally fixedly connected to the inside of the housing, the drive end of the second motor is fixedly connected to a transmission connecting rod, the outer sides of the rotating shaft are rotatably connected to the inside of the housing, and the drive end of the first motor is fixedly connected to the outside of the rotating shaft.

[0014] By adopting the above technical solution, the second motor in the assembly, fixed inside the outer casing, drives the transmission linkage to rotate, thereby causing the finishing plate to swing or rotate. Simultaneously, the first motor drives the rotating shaft, whose two sides are rotatably connected inside the outer casing, causing pulleys to roll along the telescopic hollow column, thus moving the finishing mechanism laterally. Construction personnel can precisely control the amplitude and frequency of the transmission linkage by adjusting the speed and direction of the second motor according to the actual setting state of the concrete, thereby flexibly adjusting the movement of the finishing plate to achieve troweling operations with different intensities and frequencies. This realizes intelligent adjustment of the troweling action during the finishing process, effectively addressing complex changes during concrete setting, significantly improving finishing quality, and ensuring that the flatness and density of the concrete surface meet construction standards.

[0015] Preferably, the other end of the transmission link is rotatably connected to a slurry receiving plate outside the protruding shaft, and the two outer shells are fixedly connected to a connecting column on their opposite inner sides, with a sliding column slidably connected inside the connecting column.

[0016] By adopting the above technical solution, in the secondary finishing of concrete, the motor 2 within the adjusting component drives the transmission linkage, and the protruding shaft at the other end of the transmission linkage drives the finishing plate to swing or rotate, thereby achieving the finishing of the concrete surface. Simultaneously, according to the required width of the construction area, the sliding column 1 can be manually pushed to slide within the connecting column, adjusting the distance between the two outer shells, and thus changing the spacing of the finishing mechanisms on both sides to adapt to concrete construction surfaces of different widths. The rotational connection between the transmission linkage and the finishing plate ensures the flexibility and efficiency of the finishing action, while the sliding cooperation between the connecting column and the sliding column 1 gives the device the ability to cope with diverse construction scenarios. The synergistic effect of both ensures the quality and efficiency of the finishing operation and significantly improves the versatility and construction adaptability of the device.

[0017] Preferably, a bevel gear one is rotatably connected inside the corner support block, a rotating connecting block is rotatably connected outside the corner support block, and a bevel gear two is rotatably connected inside the corner support block.

[0018] By adopting the above technical solution, when the secondary concrete finishing process device is started, the power source drives the first bevel gear inside the corner support block to rotate. The first bevel gear transmits power to the rotating connecting block through meshing with the second bevel gear. Since the rotating connecting block is externally rotatably connected to the corner support block and externally fixedly connected to the telescopic hollow column, under the action of transmission, the telescopic hollow column smoothly unfolds to the horizontal working position around the connection point of the corner support block, realizing efficient power conversion. Combined with the rotational design of the rotating connecting block, it ensures that the unfolding process of the telescopic hollow column is precise and controllable, and the angle is consistent, providing a reliable foundation for the stable operation of the subsequent finishing mechanism. At the same time, the folded state can effectively reduce the size of the device, making it convenient for transportation and storage.

[0019] Preferably, the teeth of the second bevel gear are externally engaged with the outside of the first bevel gear, and the externally fixed connection of the rotating connecting block is fixedly connected to both ends of the telescopic hollow column.

[0020] By adopting the above technical solution, when the device needs to be deployed for operation, the drive source drives the first bevel gear to rotate. Since the outer teeth of the second bevel gear are tightly meshed with the first bevel gear, the rotational power of the first bevel gear is transmitted to the second bevel gear, causing the second bevel gear to rotate synchronously. The rotating connecting block is fixedly connected to the second bevel gear, and its outer side is fixed to both ends of the telescopic hollow column. Therefore, under the drive of the second bevel gear, the rotating connecting block rotates around the connection point, thereby pushing the telescopic hollow column to unfold smoothly, laying the foundation for the efficient operation of the subsequent slurry collection mechanism. It also facilitates the folding and storage of the device in the non-operational state, improving the flexibility and practicality of the device.

[0021] Preferably, the scraper assembly includes a fixed insertion column, the bottom of the support column is fixedly connected to the fixed insertion column, the outside of the fixed insertion column is slidably connected to a sliding ring, the upper side of the sliding ring is fixedly connected to a plurality of sliding columns, and the outside of the sliding columns is slidably connected in the bottom groove of the support column.

[0022] By adopting the above technical solution, after the secondary finishing of the concrete is completed, the construction workers push the sliding ring to slide on the fixed insertion column. Since multiple sliding columns are fixedly connected to the upper side of the sliding ring, the movement of the sliding ring causes the sliding columns to move synchronously in the groove at the bottom of the support column, thereby causing the scraping component to descend to the concrete surface. At this time, the construction workers pull the support column to move, and the scraping component, through the cooperation of the sliding columns and the sliding ring, scrapes the concrete surface after finishing, removes excess slurry and distributes it evenly, realizing flexible adjustment of the scraping height and stable support, effectively eliminating the unevenness of the concrete surface after finishing, improving the surface flatness and smoothness, and ensuring the final quality of concrete construction.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The device uses a motor to drive a pulley to move along a telescopic hollow column, which, in conjunction with a motor to drive the slurry-collecting plate to swing or rotate, achieves an automated composite action of movement and troweling. Compared with traditional manual troweling, this device can significantly improve slurry-collecting efficiency, cover a larger area, and move faster. At the same time, the speed and direction of the motor are adjustable, allowing construction workers to adjust the amplitude and frequency of the slurry-collecting plate in real time according to the actual setting state of the concrete. When the concrete sets quickly, the troweling pressure can be increased, and when the initial setting is slow, the speed can be reduced to avoid excessive disturbance, thereby enhancing the slurry-collecting effect, ensuring the flatness and density of the concrete surface, and reducing quality problems such as sanding and cracking caused by improper slurry-collecting in the later stages.

[0025] 2. Through the meshing transmission of bevel gear one and bevel gear two, the telescopic hollow column is guaranteed to have a precise angle and synchronized movement when it is deployed, avoiding tilting or asymmetry caused by manual operation. This ensures that the slurry collection mechanism is in the optimal working position. After the tooth groove and tooth ring mesh and fix the slurry collection mechanism, it can effectively resist vibration and external force interference during operation, prevent it from sliding and deviating on the telescopic hollow column, and ensure that the slurry collection trajectory is stable and consistent, laying the foundation for high-quality slurry collection operations.

[0035] The grout collection mechanism 5 includes a pulley 52, which slides outside the telescopic hollow column 3, driving the grout collection mechanism 5 to move laterally along the telescopic hollow column 3 to achieve grout collection and coverage of the concrete surface. The pulley 52 is slidably connected to the outside of the telescopic hollow column 3. A rotating shaft 55 is fixedly connected to the middle of the pulley 52. ​​The rotating shaft 55 is used to transmit the power of the motor 51 to the pulley 52, driving the pulley 52 to rotate. The pulley 52 is fixedly connected to the outside of the outer shell 4. A retaining ring 53 is fixedly connected to the outside of the pulley 52. ​​The retaining ring 53 is used to engage with the telescopic hollow column 3. The telescopic component 54 is used to lock and adjust the position of the grout collection mechanism 5 on the telescopic hollow column 3. The telescopic component 54 is provided on the outside of the toothed ring 53. The telescopic component 54 is used to control the position of the grout collection mechanism 5 on the telescopic hollow column 3. The toothed groove 541 is opened on the outside of the telescopic hollow column 3 and engages or disengages with the toothed ring 53. The adjusting component 56 is provided inside the outer shell 4. The adjusting component 56 is used to adjust the movement of the grout collection plate 563 to adapt to different concrete setting states and construction requirements. The motor 51 is fixedly connected to the outside of the outer shell 4.

[0036] The telescopic assembly 54 includes a toothed groove 541, which is used to engage or disengage with the toothed ring 53 to fix and adjust the position of the slurry collection mechanism 5. Its internal groove design is precisely matched with the toothed ring 53 to ensure stability when locked. The internal groove of the toothed groove 541 is engaged with the outside of the toothed ring 53. The outside of the toothed groove 541 is opened on the outside of the telescopic hollow column 3. The inside of the telescopic hollow column 3 is slidably connected to a hollow telescopic column core 542. The hollow telescopic column core 542 changes the length of the telescopic hollow column 3 by sliding inside the telescopic hollow column 3.

[0037] Adjustment component 56 includes motor 561, which provides power for the movement of the finishing plate 563. By controlling the motor speed and direction, the swing or rotation amplitude and frequency of the finishing plate 563 are adjusted. Motor 561 is externally fixedly connected to the inside of housing 4. A transmission link 562 is fixedly connected to the drive end of motor 561. The transmission link 562 is used to convert the rotational motion of motor 561 into the swing or rotational motion of finishing plate 563. Finishing plate 563 directly acts on the concrete surface to perform troweling and finishing operations. Its shape and angle are optimized to effectively remove air bubbles from the concrete surface. Rotation shaft 5 The outer sides of the 5 are rotatably connected to the inside of the outer shell 4. The drive end of the motor 51 is fixedly connected to the outside of the rotating shaft 55. The other end of the transmission connecting rod 562 protrudes from the outside of the shaft and is rotatably connected to the slurry collecting plate 563. The two inner sides of the two outer shells 4 are fixedly connected to the connecting column 6. The connecting column 6 is used to connect the two slurry collecting mechanisms 5 to ensure that the two slurry collecting mechanisms 5 work together. It is made of high-strength material and has sufficient rigidity. The connecting column 6 is slidably connected to the inside of the connecting column 6. The sliding column 7 is used to slide in the connecting column 6 to adjust the distance between the two slurry collecting mechanisms 5 to adapt to construction areas of different widths. The sliding is smooth and the positioning is convenient.

[0038] Specifically, efficient grout removal is achieved through modular collaboration. Before construction, the telescopic hollow column 3 is unfolded by the bevel gear transmission of the folding mechanism 2, and the hollow telescopic column core 542 and sliding column 7 are adjusted to expand the working width. During operation, motor 1 51 drives pulley 52 to move along the telescopic hollow column 3, and motor 2 561 drives the grout removal plate 563 to smear the concrete surface through the transmission connecting rod 562. At the same time, the locking ring 53 and the locking groove 541 engage to lock the working position. After the grout removal is completed, the sliding ring 82 drives the sliding column 2 83 to descend, and the grout scraping assembly 8 performs fine leveling treatment on the area of ​​the support column 1.

[0039] Reference Figure 1 , Figure 5 and Figure 6 The folding mechanism 2 includes a corner support block 21. The bottom of the corner support block 21 is fixedly connected to the top of the support column 1. The two outer ends of the corner support block 21 are rotatably connected to telescopic hollow columns 3. The corner support block 21 serves as the fulcrum for the rotation of the telescopic hollow columns 3. The inside of the corner support block 21 is rotatably connected to a bevel gear 22, which meshes with a bevel gear 23 to transmit power and change the transmission direction. The outside of the corner support block 21 is rotatably connected to a rotating connecting block 24. The inside of the corner support block 21 is rotatably connected to a bevel gear 23. The teeth of the bevel gear 23 are externally meshed with the outside of the bevel gear 22. The outside of the rotating connecting block 24 is fixedly connected to both ends of the telescopic hollow columns 3. The rotating connecting block 24 is fixed to both ends of the telescopic hollow columns 3 and drives the telescopic hollow columns 3 to rotate under the transmission of the bevel gears, thereby realizing folding or unfolding.

[0040] The scraper assembly 8 includes a fixed insertion column 81. The fixed insertion column 81 is fixedly connected to the bottom of the support column 1. The fixed insertion column 81 is fixedly connected to the bottom of the support column 1, providing an installation base for the sliding ring 82 and the second sliding column 83. The external of the fixed insertion column 81 is slidably connected to the sliding ring 82. The sliding ring 82 is used to slide up and down along the fixed insertion column 81, driving the second sliding column 83 and the scraper component to move, thereby realizing the scraping height adjustment. The upper side of the sliding ring 82 is fixedly connected to multiple second sliding columns 83. The second sliding columns 83 are used to slide in the groove at the bottom of the support column 1 to ensure the stability during scraping. In cooperation with the sliding ring 82, the scraper assembly 8 can be stably raised, lowered and moved. The external of the second sliding column 83 is slidably connected in the groove at the bottom of the support column 1.

[0041] Specifically, the folding mechanism 2 and the scraping assembly 8 are made of high-strength cast steel and alloy steel, respectively. They achieve functional synergy through a precision transmission structure. Before operation, the drive source rotates the first bevel gear 22 within the folding mechanism 2. Through the meshing transmission of the second bevel gear 23, the power is transmitted to the rotating connecting block 24, which in turn drives the telescopic hollow column 3 to unfold around the corner support block 21 to a horizontal working position. The corner support block 21 serves as a stable fulcrum, ensuring smooth and precise unfolding. After the grouting operation is completed, the sliding ring 82 of the scraping assembly 8 is pushed, causing it to slide along the fixed insertion column 81. This drives the second sliding column 83 to move within the groove at the bottom of the support column 1, lowering the scraping component to the concrete surface for smoothing and finishing the area around the support column 1, effectively improving construction efficiency and concrete surface quality.

[0042] The implementation principle of this application embodiment is as follows: The support column 1 is placed at the edge of the concrete area to be grouted. The folding mechanism 2 is in a retracted state, and the telescopic hollow column 3 is folded near the top of the support column 1, facilitating the movement and positioning of the device. By adjusting the telescopic component 54, the toothed groove 541 is separated from the toothed ring 53, allowing for free adjustment of the length of the telescopic hollow column 3 to adapt to different construction ranges and concrete surface conditions. The sliding column 83 is adjusted to a suitable position within the groove at the bottom of the support column 1, ensuring that the grout scraping component 8 can smoothly perform subsequent grout scraping operations. By adjusting the support... The position of column 1 drives bevel gear 22 to rotate, which in turn drives rotating connecting block 24 to rotate through meshing with bevel gear 23. This causes the telescopic hollow column 3 to unfold around the corner support block 21 to a horizontal working position. Adjusting the telescopic assembly 54 pushes the hollow telescopic column core 542 to slide inside the telescopic hollow column 3, causing the retaining groove 541 to mesh with the retaining ring 53, fixing the position of the slurry collection mechanism 5 on the telescopic hollow column 3. Through motor 51, motor 51 drives rotating shaft 55 to rotate, causing pulley 52 to roll outside the telescopic hollow column 3, so that the slurry collection mechanism 5 moves along the telescopic hollow column. The core column 3 moves, while the retaining ring 53 rotates within the retaining groove 541, ensuring stable movement of the grout-collecting mechanism 5. This, in conjunction with the second motor 561, drives the grout-collecting plate 563 to swing or rotate via the transmission connecting rod 562, performing grout-collecting operations on the concrete surface. During the grout-collecting process, the angle of the grout-collecting plate 563 can be adjusted by changing the speed and direction of the second motor 561 according to the actual condition of the concrete surface, achieving the best grout-collecting effect. The two outer shells 4 are connected by the connecting column 6 and the sliding column 7. The sliding column 7 slides within the connecting column 6, allowing for fine-tuning. The distance between the two grout collection mechanisms 5 can accommodate construction areas of different widths. After the grout collection operation is completed, the sliding ring 82 is pushed to slide on the fixed insertion column 81, which drives the second sliding column 83 to move in the groove at the bottom of the support column 1, so that the grout scraping component 8 descends to the concrete surface. By using the cooperation of the second sliding column 83 and the sliding ring 82, the concrete surface after grout collection is scraped to remove excess grout, making the concrete surface smoother. After the grout scraping is completed, the folding mechanism 2 is folded up, the telescopic hollow column 3 is folded back, and the grout scraping component 8 is put away, which facilitates the transportation and storage of the device.
