Description

Technical Field

[0001] This invention belongs to the field of cleaning technology for filter channels, specifically a device and method for cleaning PVC filter channels in concrete post-pouring strips. Background Technology

[0002] The PVC guide channel cleaning device for concrete post-pouring strips is a special equipment used in the construction of post-pouring strips. Its core function is to efficiently clean debris in the gaps of the post-pouring strip, ensuring the quality of the concrete pouring and the waterproof performance of the structure. It also cleans up dust, sand, wood chips, loose concrete and other debris accumulated during the construction of the post-pouring strip, solving the problem that manual cleaning is difficult to reach areas with dense reinforcement.

[0003] A Chinese patent with publication number CN222402424U discloses a handheld pre-embedded rebar cleaning device, including a handheld part and a cleaning part connected to the handheld part. The cleaning part includes a drive assembly and a cleaning assembly. The cleaning assembly includes a rotating housing and a cleaning brush. The rotating housing encloses a cleaning chamber, into which the pre-embedded rebar to be cleaned extends. The cleaning brush, mounted on the side wall of the cleaning chamber, contacts the outer wall of the pre-embedded rebar. The output end of the drive assembly is connected to the rotating housing. Driven by the drive assembly, the rotating housing rotates, thereby causing the cleaning brush to rub against the pre-embedded rebar, achieving cleaning of the rebar surface. The handheld design of this device makes operation simple and convenient, improving cleaning efficiency. Simultaneously, cleaning the pre-embedded rebar within the cleaning chamber effectively prevents the splashing of rust residue, ensuring the safety of the operator.

[0004] The existing PVC filter channel cleaning device for concrete post-pouring strips has poor overall operational flexibility when carrying out cleaning operations. The steel reinforcement structure laid at the pre-embedded position of the post-pouring strip will block and obstruct the cleaning operation, making it difficult for cleaning tools to pass through the gaps between the steel reinforcement to remove impurities. At the same time, large particles of debris remaining in the pouring area cannot be cleaned and collected efficiently, which ultimately seriously reduces the overall cleaning effect of the post-pouring strip.

[0005] Therefore, the present invention provides a device and method for cleaning PVC filter channels in post-cast concrete strips. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of inconvenience in removing debris according to the site conditions, this invention proposes a PVC guide filter channel cleaning device and method for concrete post-pouring strips.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A PVC guide filter channel cleaning device for post-cast concrete strips, comprising a protective frame, wheels at the bottom of the protective frame, a support cylinder inside the protective frame, an adjustment mechanism for adjusting the position of the support cylinder inside the protective frame, a support column rotatably mounted inside the support cylinder, a hollow tube passing through the support column, a drive mechanism for adjusting the position of the hollow tube on the support column, a ring frame fixedly connected to the bottom end of the hollow tube, and a connecting shaft circumferentially mounted on the ring frame. The support column is provided with a ring array of support shafts, and a load-bearing plate is movably mounted on the support shaft. A limit cylinder is provided on the load-bearing plate and is movably connected to the connecting shaft. A hollow groove is provided inside the load-bearing plate. A square box is fixedly installed inside the protective frame. A separation mechanism is provided inside the square box. An exhaust fan is fixedly installed inside the square box and is connected to the separation mechanism. A concave groove is provided inside the load-bearing plate. A second electric push rod is provided inside the concave groove. A concave frame is provided inside the concave groove. A crushing mechanism is provided inside the concave frame.

[0008] By adopting the above scheme, when cleaning the PVC guide filter channel of the concrete post-pouring strip using the cleaning device, the protective frame is easily moved by the traveling wheels, which in turn moves the support column, causing the load-bearing plate to move synchronously. The load-bearing plate is initially in a vertical state. After the load-bearing plate moves to the cleaning location, the position of the hollow tube is adjusted by the drive mechanism, and the hollow channel is moved to the cleaning location. The opening and closing state of the hollow channel is controlled by the solenoid valve, and the movement of the exhaust fan, in conjunction with the separation mechanism, generates suction in the hollow channel. Impurities and debris are forced into the separation mechanism through the hollow channel and hollow tube. The separation mechanism screens and processes the debris, and after the debris is removed, the purpose of cleaning the PVC guide filter channel of the concrete post-pouring strip is achieved. The vertical movement of the load-bearing plate aligns the hollow channel with the debris and impurities, facilitating the passage of the embedded steel bars and the removal of impurities on the bottom surface, which is conducive to subsequent concrete pouring and ensures the quality of concrete pouring. When there are too many impurities on the bottom surface of the poured concrete, the hollow tube is adjusted by the drive mechanism during cleaning. This causes the hollow tube to move downwards, and through the ring frame and connecting shaft, pressure is applied to one end of the load-bearing plate. After the load-bearing plate is pressed, the angle of the load-bearing plate is adjusted by the support shaft, which simultaneously drives the cleaning brush to move, making the load-bearing plate horizontal with the ground. At the same time, the position of the support cylinder can be adjusted by the adjustment mechanism, so that the bottom of the cleaning brush contacts the ground, driving the support column to rotate, which in turn drives the cleaning brush to rotate. The rotating cleaning brush can clean the poured concrete surface. A control valve is installed at the bottom of the hollow tube to control the opening and closing of the hollow tube. When cleaning the poured concrete surface, the hollow tube is opened, and the hollow groove is sealed by the solenoid valve. Then, when the exhaust fan is working, the hollow tube generates suction, which can effectively extract and process floating dust and impurities, achieving the purpose of impurity removal and further ensuring the cleanliness of the PVC filter channel of the post-pouring strip.

The position of the support column and the load-bearing plate can be adjusted through the connecting block. When the support cylinder moves, it will drive the guide block to move.

[0019] By adopting the above scheme, the hollow tube is made of magnetic material, and an electromagnet is embedded inside the guide plate. When the hollow tube moves, the guide groove and the guide plate work together to guide the hollow tube, so that the hollow tube moves smoothly.

[0021] By adopting the above scheme, the opening and closing state of the hollow pipe can be adjusted by the solenoid valve. When cleaning the PVC filter channel of the concrete post-pouring strip, when extracting impurities and debris through the hollow pipe, the cleaning debris will enter the separation box through the airflow by the cooperation of the rotary joint, No. 1 connector and No. 2 connector.

[0024] A method for using a PVC guide filter channel cleaning device for post-cast concrete strips includes the following steps: S1. When cleaning the PVC filter channel of the post-pouring strip, the protective frame can be moved by the walking wheels, which in turn moves the support column and drives the load-bearing plate to move synchronously. S2. The load-bearing plate is initially in a vertical state. After moving the load-bearing plate to a clean location; S3. The position of the hollow tube is adjusted by the drive mechanism, and the hollow tank is moved to the cleaning location. Then, the opening and closing state of the hollow tank is controlled by the solenoid valve. S4. The operation of the exhaust fan, in conjunction with the separation mechanism, generates suction in the hollow trough. Impurities and debris are fed into the separation mechanism through the hollow trough and hollow pipe, where they are screened and processed. S5. After removing debris, the purpose of cleaning the PVC filter channel of the concrete post-pouring strip is achieved.

[0025] The beneficial effects of this invention are as follows: 1. The present invention discloses a cleaning device and method for PVC guide filter channels in concrete post-pouring strips. Through a pre-designed hollow groove and hollow tube structure, the cleaning of PVC guide filter channels in post-pouring strips can be conveniently achieved. The load-bearing plate is initially arranged vertically. After it moves to the cleaning operation point, the operation of the first electric push rod drives the connecting block to move. The connecting block adjusts the position of the support column and the load-bearing plate. During the movement of the support cylinder, the guide block will move synchronously. The guide shaft and the guide block cooperate to guide and limit the support cylinder, ensuring the smooth movement of the support cylinder, thereby enabling the load-bearing plate to move vertically. At this time, the hollow groove can be aligned with debris and impurities. The vertical movement of the load-bearing plate can smoothly pass through the pre-embedded steel bars, completing the cleaning of impurities on the ground, providing convenience for subsequent concrete pouring construction, and effectively ensuring the quality of concrete pouring.

[0026] 2. The PVC guide filter channel cleaning device and method for concrete post-pouring strips described in this invention, through the setting of a load-bearing plate and a hollow tube, allows for flexible adjustment of the cleaning operation mode to adapt to different construction scenarios. When there is a large accumulation of impurities on the bottom surface of the poured concrete, the second motor is started to drive the transmission gear to rotate. The transmission gear cooperates with the rack to adjust the position of the hollow tube. During the movement of the hollow tube, the guide groove and guide plate cooperate to achieve guidance and limit, ensuring that the hollow tube moves smoothly downward. During the downward movement, the ring frame and connecting shaft cooperate to apply pressure to one end of the load-bearing plate. Under the action of pressure, the load-bearing plate completes the angle adjustment through the support shaft, and at the same time drives the cleaning brush to move synchronously. After adjustment, the load-bearing plate is kept horizontal with the ground. Then, the first motor is started, and the drive gear is driven to rotate through the reducer. The drive gear cooperates with the driven gear to drive the support column to rotate. The support cylinder engages with the outer surface of the support column to ensure that the support column rotates smoothly, thereby driving the cleaning brush to rotate and completing the cleaning operation of impurities on the bottom surface of the poured concrete.

[0027] 3. The PVC guide filter channel cleaning device and method for post-cast concrete strips described in this invention, through the setting of a separation box and filter plate, can conveniently realize the separation and recycling of debris and impurities after cleaning. Under the action of wind, impurities are transported into the separation box and flow through the filter plate. The debris and impurities are effectively separated by the filter plate screening, completing the separation and collection of debris. After the debris and impurities are collected, the collected debris and impurities can be centrally processed through the openable and closable sealing plate on the side of the separation box and the detachable filter plate, which facilitates the graded recycling and reuse of debris and impurities.

[0028] 4. The PVC guide filter channel cleaning device and method for concrete post-pouring strips of the present invention uses a set crushing blade to facilitate the crushing and removal of larger particles. When the crushing mechanism is driven to crush particles, the drive motor runs to generate driving force, which drives the drive rod to move synchronously. The drive rod then drives the crushing blade to move. When the crushing blade comes into contact with the particles, it can perform shearing and crushing treatment on the particles, which is convenient for subsequent particle cleaning and discharge. This effectively improves the efficiency of cleaning debris on the bottom surface and ensures a stable overall cleanliness of the bottom surface. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 10 As shown in the embodiment of the present invention, a PVC guide filter channel cleaning device for concrete post-pouring strip includes a protective frame 1, a walking wheel 2 at the bottom of the protective frame 1, a support cylinder 5 inside the protective frame 1, an adjustment mechanism for adjusting the position of the support cylinder 5 inside the protective frame 1, a support column 10 rotatably arranged inside the support cylinder 5, a hollow tube 16 passing through the support column 10, a drive mechanism for adjusting the position of the hollow tube 16 on the support column 10, a ring frame 19 fixedly connected to the bottom end of the hollow tube 16, a connecting shaft 21 arranged around the ring frame 19, a support shaft 24 arranged in a ring array on the support column 10, a load-bearing plate 22 movably arranged on the support shaft 24, a limit cylinder 23 arranged on the load-bearing plate 22, and the limit cylinder 23 movably connected to the connecting shaft 21, and a hollow groove 26 arranged inside the load-bearing plate 22; A square box 34 is fixedly installed inside the protective frame 1. A separation mechanism is installed inside the square box 34. An exhaust fan 38 is fixedly installed inside the square box 34 and is connected to the separation mechanism. The load-bearing plate 22 has a concave groove 45 inside, a second electric push rod 47 inside the concave groove 45, a concave frame 41 inside the concave groove 45, and a crushing mechanism inside the concave frame 41.

[0034] When cleaning the PVC guide filter channel of the concrete post-pouring strip using the cleaning device, the protective frame 1 is moved by the walking wheels 2, which in turn moves the support column 10, thereby driving the load-bearing plate 22 to move synchronously. The load-bearing plate 22 is initially in a vertical state. After the load-bearing plate 22 is moved to the cleaning location, the position of the hollow tube 16 is adjusted by the drive mechanism. At the same time, the hollow channel 26 is moved to the cleaning location. The opening and closing state of the hollow channel 26 is controlled by the solenoid valve 27. The exhaust fan 38 moves and, with the cooperation of the separation mechanism, generates suction in the hollow channel 26. Impurities and debris are forced into the separation mechanism through the hollow channel 26 and the hollow tube 16. The separation mechanism screens and processes the debris. After the debris is removed, the purpose of cleaning the PVC guide filter channel of the concrete post-pouring strip is achieved. The vertical movement of the load-bearing plate 22 aligns the hollow channel 26 with the debris and impurities, making it easy to pass through the embedded steel bars and remove impurities on the bottom surface. This facilitates subsequent concrete pouring and ensures the quality of the concrete pouring. When there are too many impurities on the bottom surface of the poured concrete, during the cleaning process, the position of the hollow tube 16 is adjusted through the drive mechanism, causing the hollow tube 16 to move downwards. Through the cooperation of the ring frame 19 and the connecting shaft 21, pressure is applied to one end of the load-bearing plate 22. After one end of the load-bearing plate 22 is pressed, the angle of the load-bearing plate 22 is adjusted through the support shaft 24, which simultaneously drives the cleaning brush 25 to move. After moving 90 degrees, the load-bearing plate 22 is brought to a horizontal position with the ground. At the same time, through the adjustment mechanism, the position of the support cylinder 5 can be adjusted so that the bottom of the cleaning brush 25 contacts the ground. The drive support column 10 rotates, which in turn drives the cleaning brush 25 to rotate. The rotating cleaning brush 25 can clean the casting surface. A control valve is set at the bottom of the hollow tube 16 to control the opening and closing of the hollow tube 16. When cleaning the casting surface, the hollow tube 16 is opened, and the hollow groove 26 is sealed by the solenoid valve 27. Then, when the exhaust fan 38 is working, the hollow tube 16 generates suction, which can effectively extract and process floating dust and impurities, achieve the purpose of removing impurities, and further ensure the cleanliness of the PVC filter channel of the post-cast strip. During the initial cleaning and pretreatment of the poured ground, to avoid large-volume impurities affecting the overall cleaning effect, the position of the concave frame 41 can be adjusted by driving the second electric push rod 47. While the concave frame 41 moves accordingly, the position of the crushing mechanism is simultaneously adjusted. When the crushing mechanism is driven to operate, it can accurately contact large particles on the ground and crush and refine the blocky particles, making it easier to thoroughly clean large impurities. For stubborn hard particles that are difficult to crush by conventional methods, it can be used in conjunction with the sweeping brush 25 to clean and collect these particles in a unified manner, making it convenient for subsequent centralized collection and disposal, effectively improving the adaptability and flexibility of the ground cleaning operation.

The power supply component 3 is electrically connected to the controller 4. The crushing mechanism includes a drive rod 42, a crushing blade 43, a housing 44, and a power motor 46. The drive rod 42 is rotatably installed inside the concave frame 41. The crushing blade 43 is arrayed on the drive rod 42. The housing 44 is fixed on the concave frame 41. The power motor 46 is fixed inside the housing 44, and the output end of the power motor 46 is fixedly connected to one end of the drive rod 42. The controller 4 is electrically connected to the electronic equipment on the PVC filter channel cleaning device for the concrete post-pouring strip, and can control the operation of the PVC filter channel cleaning device for the concrete post-pouring strip. When the crushing mechanism performs particle crushing operations, the drive motor 46 operates to generate driving force, which drives the drive rod 42 to move synchronously. The drive rod 42 then drives the crushing blade 43 to move. When the crushing blade 43 comes into full contact with the particles, it can perform shearing and crushing treatment on the particles, which facilitates the subsequent cleaning and discharge of particles, effectively improves the efficiency of cleaning debris on the bottom surface, and stably ensures the overall cleanliness of the bottom surface.

Controlling the operation of motor 13 will drive the reducer 14 to move. When the reducer 14 moves, it will drive the drive gear 15 to rotate. Through the engagement of the driven gear 11, it will drive the support column 10 to rotate. The support cylinder 5 engages with the outer surface of the support column 10, so that the support column 10 rotates smoothly.

When the hollow tube 16 moves, the guide groove 17 and the guide plate 18 cooperate to guide the hollow tube 16, so that the hollow tube 16 moves smoothly. After the hollow tube 16 moves to the predetermined position, the electromagnet is controlled to work to generate a strong magnet, which can be used to locate the position of the hollow tube 16.

[0040] Furthermore, a dust suction port 20 is provided at the bottom end of the hollow tube 16, and the dust suction port 20 is located on one side of the ring frame 19.

[0043] A method for using a PVC guide filter channel cleaning device for post-cast concrete strips includes the following steps: S1.

Then, the opening and closing state of the hollow trough 26 is controlled by the solenoid valve 27. S4. The movement of the exhaust fan 38, in conjunction with the separation mechanism, causes the hollow trough 26 to generate suction. Impurities and debris are fed into the separation mechanism through the connection between the hollow trough 26 and the hollow tube 16, where they are screened and processed. S5. After removing debris, the purpose of cleaning the PVC filter channel of the concrete post-pouring strip is achieved.

[0044] Working principle: First, when cleaning the PVC guide filter channel of the concrete post-pouring strip using the cleaning device, the protective frame 1 is moved easily by the walking wheels 2, which in turn moves the support column 10, thereby driving the load-bearing plate 22 to move synchronously. The load-bearing plate 22 is initially in a vertical state. After the load-bearing plate 22 is moved to the cleaning location, the operation of the first electric push rod 8 is controlled to push the connecting block 9 to move. The position of the support column 10 and the load-bearing plate 22 can be adjusted through the connecting block 9. When the support cylinder 5 moves, it will drive the guide block 6 to move. Through the cooperation of the guide shaft 7 and the guide block 6, the support cylinder 5 is guided, so that the support cylinder 5 moves smoothly. The load-bearing plate 22 moves vertically, so that the hollow groove 26 is aligned with debris and impurities. The solenoid valve 27 controls the movement of the load-bearing plate 22. With the hollow trough 26 open or closed, the exhaust fan 38 moves in conjunction with the separation mechanism, causing the hollow trough 26 to generate suction. Impurities and debris are carried into the separation box 35 by the airflow through the hollow trough 26 and hollow pipe 16. After flowing through the filter plate 37, the debris and debris are separated, achieving the purpose of debris separation and collection. After the debris and debris are collected, the side of the separation box 35 is equipped with an openable and closable sealing plate, and the filter plate 37 is removable, allowing for the processing of the removed debris and impurities. This facilitates the graded recycling of debris and impurities. The load-bearing plate 22 moves vertically, facilitating the passage of embedded steel bars to remove impurities from the bottom surface, facilitating subsequent concrete pouring and ensuring the quality of the concrete pouring. When there are too many impurities on the bottom surface during the cleaning process, the control system is activated. The movement of motor 31 drives the transmission gear 32. When the transmission gear 32 moves, it adjusts the position of the hollow tube 16 through the rack 29. As the hollow tube 16 moves, it is guided by the guide groove 17 and guide plate 18, allowing it to move smoothly. When the hollow tube 16 moves downwards, it applies pressure to one end of the load-bearing plate 22 through the ring frame 19 and connecting shaft 21. After being pressed, the load-bearing plate 22's angle is adjusted via the support shaft 24, simultaneously driving the cleaning brush 25 to move. After moving 90 degrees, the load-bearing plate 22 is level with the ground. Controlling motor 13 drives the reducer 14, which in turn drives the drive gear 15 to rotate, through the driven gear... The wheel 11, when engaged, drives the support column 10 to rotate. The support cylinder 5 engages with the outer surface of the support column 10, allowing the support column 10 to rotate smoothly. This rotation of the support column 10, in turn, drives the cleaning brush 25 to rotate. The cleaning brush 25 cleans the poured surface. A control valve is located at the bottom of the hollow tube 16, controlling its opening and closing. When cleaning the poured surface, the hollow tube 16 is opened, and simultaneously, the hollow groove 26 is sealed via the solenoid valve 27. When the exhaust fan 38 operates, the hollow tube 16 generates suction, effectively extracting and processing floating dust and impurities, achieving the purpose of impurity removal. This further ensures the cleanliness of the PVC filter channel in the post-pouring strip. After the impurities are carried by the airflow into the separation box 35, they flow through the filter plate 37...The filter plate 37 separates debris and impurities, achieving the purpose of separating and collecting debris. After the debris and impurities are collected, an openable and closable sealing plate is provided on the side of the separation box 35. The filter plate 37 is removable, allowing for the processing of the removed debris and impurities, facilitating the graded recycling of debris and impurities.
