Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and specifically relates to a concrete point-by-point compaction device and its usage method. Background Art

[0002] When constructing concrete, it is necessary to first pour the concrete into the formwork. However, due to the friction and adhesion between the aggregates, the concrete cannot automatically fill the formwork, and its interior is loose. At this time, it is necessary to vibrate and shape the concrete to endow the concrete products or structures with a certain shape, strength, impermeability, and durability. In the prior art, generally a single vibrating rod is used for concrete compaction operations, and workers need to slide inside the formwork and manually drag the vibrating rod, which reduces the overall compaction uniformity and increases the manual labor intensity.

[0003] A patent of Chinese Patent Application CN211850907U discloses a concrete point-by-point compaction mechanism. The key points of its technical solution are: including a chassis device for moving, and also including a lifting device for lifting. A support device is installed on the chassis device, and a vibration device is arranged below the support device. The concrete point-by-point compaction mechanism described in this utility model generates multi-point vibration to compact the concrete through the setting of the vibration device, facilitates the lifting of the vibration device through the setting of the lifting device, reduces the manual labor intensity, and ensures that the vibration device is located above the working location through the setting of the support device.

[0004] In view of the above and related prior arts, the inventor believes that the following defects often exist: Although the concrete point-by-point compaction device in the prior art can reduce the manual labor intensity, the support plate of this device is connected to the support device through steel cables, making the support plate of this device prone to shaking back and forth, left and right during use, resulting in a decrease in stability during work, and setting multiple rows of uniformly arranged vibrating rods to achieve uniform and comprehensive compaction increases the construction cost and is not conducive to meeting the actual use requirements.

[0005] Therefore, the present invention provides a concrete point-by-point compaction device and its usage method. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A concrete point compaction device described in the present invention includes a vehicle body; an outrigger beam is fixedly connected to the top of the vehicle body; a winch is arranged inside the vehicle body; a sling is connected to the surface of the winch, and the other end of the sling passes through the top of the outrigger beam and is fixedly connected to a suspension frame; a support plate is fixedly connected to the top of the outrigger beam; a group of guide rods are fixedly connected to the upper side of the suspension frame, and the guide rods penetrate through the support plate and are slidably connected thereto; a sliding seat is slidably connected inside the suspension frame; a motor I is fixedly connected to one side of the suspension frame; a screw rod is fixedly connected to the surface of the output shaft of the motor I, and the screw rod is rotatably connected to the suspension frame; the screw rod penetrates through the sliding seat and is connected thereto through a screw-nut pair; two groups of elastic vibrating rods are evenly distributed on the lower side of the sliding seat; a guide plate is fixedly connected between each group of vibrating rods; a motor II is fixedly connected to the surface of the sliding seat between the two groups of vibrating rods; a turntable is fixedly connected to the surface of the output shaft of the motor II; a group of knocking rods are evenly distributed on the circumference of the side surface of the turntable. Although the concrete point compaction device in the prior art can reduce the labor intensity of workers, the support plate of this device is connected to the support device through steel cables, which makes the support plate of this device prone to shaking back and forth, left and right during use, resulting in a decrease in stability during work, and a large number of vibration rods arranged in multiple rows are used to achieve uniform and comprehensive compaction, which increases the construction cost and is not conducive to meeting the actual use requirements; at this time, when the present invention is working, the suspension frame is moved to the upper part of the concrete formwork by controlling the vehicle body, and the sling is wound and released by the winch, and then the suspension frame descends and the vibrating rods are inserted into the concrete inside the formwork. Then, the motor II is started to drive the turntable to rotate, so that the knocking rods intermittently knock the guide plate, prompting the vibrating rods to vibrate. After that, the motor I drives the screw rod to rotate forward and reverse intermittently, driving the sliding seat to reciprocate inside the suspension frame, so that the vibrating rods move horizontally and walk in the concrete, compacting the concrete at points and improving the compaction degree of the concrete. Since the vibrating rods are arranged in a moving manner, the number of vibrating rods can be reduced, the construction cost can be reduced, and by setting the guide rods to limit the suspension frame, the problem of the suspension frame shaking back and forth, left and right during work can be avoided.

[0008] Preferably, an installation groove is opened at the end of the knocking rod away from the turntable; a guide wheel is rotatably connected to the inside of the installation groove through a rotating pin. By setting the guide wheel, when the knocking rod moves to the position of the guide plate, the guide wheel contacts the guide plate and rolls on its surface, thereby reducing the resistance and wear between the knocking rod and the guide plate and extending the service life of the device.

[0009] Preferably, a water tank is fixedly connected to the upper side of the sliding seat, and clean water is added to the inside of the water tank; a cleaning pipe is fixedly connected to the lower side of the sliding seat near the vibrating rod, and the cleaning pipe is communicated with the water tank through a control valve; after the compaction work is completed, the hoisting rope is wound up by the winch to drive the hanging frame to rise and pull out the vibrating rod from the concrete, and the hanging frame is moved away from above the formwork by controlling the vehicle body. Then, the cleaning pipe is opened through the control valve, and the clean water in the water tank flows downward through the cleaning pipe to wash the surface of the vibrating rod and remove the concrete adhered to its surface, eliminating the need for manual flushing and preventing the concrete from drying and hardening on the surface of the vibrating rod, which may cause poor subsequent vibration effects.

[0010] Preferably, a movable ring is slidably connected to the outside of the vibrating rod; an annular groove is formed on the upper side of the movable ring; an elastic rope I is fixedly connected between the movable ring and the lower side of the sliding seat; after the cleaning pipe is opened, under the impact of the water flow, the movable ring will move downward and stretch the elastic rope I, and then the scraping ring will further scrape the concrete on the surface of the vibrating rod downward, improving the cleaning efficiency of the vibrating rod. After the cleaning pipe is closed, the elastic rope I pulls the movable ring to rise and reset.

[0011] Preferably, there is a gap between the bottom of the movable ring and the vibrating rod; by setting the gap, after the water flow enters the inside of the movable ring, it can flow downward along the gap between the movable ring and the vibrating rod, enabling the movable ring to scrape the larger pieces of concrete on the surface of the vibrating rod while flushing the vibrating rod, and the water inside the movable ring can be emptied through the gap after the cleaning pipe is closed, preventing water waste and minimizing the weight of the movable ring, so that the subsequent elastic rope I can smoothly pull the movable ring to reset.

[0012] Preferably, a water collecting ring is fixedly connected to the edge of the upper side of the movable ring; the water collecting ring is arranged in a horn shape, and the diameter of the top of the water collecting ring is larger than that of the bottom; by setting the water collecting ring, the splashing water droplets can be collected, and the water droplets can flow into the inside of the movable ring along the inclined surface of the water collecting ring for flushing the surface of the vibrating rod, further reducing water waste.

[0013] Preferably, a group of coating films are evenly distributed on the inner circumference of the movable ring; an elastic block is fixedly connected in the closed cavity formed between the coating film and the inner side of the movable ring, and the elastic block is made of a water-absorbing material; a group of bent pipes are evenly distributed on the outer circumference of the movable ring; the upper end of the bent pipe is communicated with the closed cavity, and the lower end of the bent pipe extends below the movable ring and inclines upward; water collecting ports are formed on the upper and lower sides of the coating film; a first magnetic block is fixedly connected to one side of the coating film close to the vibrating rod; a second magnetic block is fixedly connected inside the lower end of the vibrating rod, and the first magnetic block and the second magnetic block repel each other when approaching; the water inside the movable ring will enter the coating film through the water collecting port and be absorbed by the elastic block, so that the inside of the elastic block is filled with water. When the movable ring moves to the bottom of the vibrating rod, the second magnetic block will generate a repulsive force on the first magnetic block. Then, the first magnetic block squeezes the elastic block through the coating film, and the water inside the elastic block is extruded. The extruded water enters the inside of the bent pipe and is sprayed obliquely upward through the lower end of the bent pipe to wash the bottom end face of the vibrating rod, so that the residual concrete on the end face of the vibrating rod can also be cleaned up, further improving the cleaning degree of the vibrating rod.

[0014] Preferably, an elastic cap is fixedly connected to one side of the coating film close to the vibrating rod, and the concave surface of the elastic cap faces the coating film; by arranging the elastic cap, when the first magnetic block drives the coating film and the elastic cap to move toward the inner side of the movable ring, the elastic cap can be buckled on the inner surface of the movable ring, so as to block the water collecting port, so that most of the water inside the elastic block can enter the inside of the bent pipe when the elastic block is squeezed, improving the utilization rate of water and thus more fully washing the end face of the vibrating rod.

[0015] Preferably, a slider is slidably connected inside the lower end of the bent pipe; a group of guide holes are evenly distributed inside the slider; an elastic rope two is fixedly connected between the side of the slider away from the vibrating rod and the inner side of the bent pipe; a group of bristles are evenly distributed on the side of the slider close to the vibrating rod; after the water flow enters the inside of the bent pipe, due to the small diameter of the guide holes, the water flow is too late to flow out through the guide holes completely. Therefore, the water flow will push the slider to move outward, driving the bristles to extend outward and stab the bottom section of the vibrating rod, further cleaning the relatively stubborn concrete on the end face of the vibrating rod. At the same time, the water flow is sprayed out synchronously through the guide holes, and the small guide holes can increase the water flow pressure, improving the cleaning efficiency of the end face of the vibrating rod.

[0016] A using method of a concrete point compaction device, which uses the above-mentioned concrete point compaction device, includes the following steps:

[0017] S1: Control the vehicle body to move the suspension frame above the concrete formwork, and wind and unwind the suspension cable through the winch. Then, the suspension frame descends and inserts the vibrating rod into the concrete inside the formwork;

[0018] S2: Start Motor 2 to drive the turntable to rotate. The knocking rod intermittently knocks the guiding plate, prompting the vibrating rod to vibrate. Then, drive the screw rod to rotate forward and reverse intermittently through Motor 1, causing the vibrating rod to translate and move around inside the concrete, and compact the concrete at different points.

[0019] S3: Wind up the sling through the winch to drive the hanging frame to rise and pull out the vibrating rod from the concrete. Move the hanging frame away from above the formwork by controlling the vehicle body. Then, open the cleaning pipe through the control valve, and the clear water in the water tank flows downward through the cleaning pipe to wash the surface of the vibrating rod.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. For the concrete point-compacting device and its using method described in the present invention, move the hanging frame to above the concrete formwork by controlling the vehicle body, and wind and unwind the sling through the winch. Then, the hanging frame descends and inserts the vibrating rod into the concrete inside the formwork. Next, start Motor 2 to drive the turntable to rotate, causing the knocking rod to intermittently knock the guiding plate, prompting the vibrating rod to vibrate. Then, drive the screw rod to rotate forward and reverse intermittently through Motor 1, driving the sliding seat to reciprocate inside the hanging frame, causing the vibrating rod to translate and move around inside the concrete, and compact the concrete at different points, improving the compactness of the concrete. Since the vibrating rod is set to be movable, the number of vibrating rods can be reduced, reducing the construction cost. And by setting the guide rod to limit the hanging frame, the problem of the hanging frame shaking back and forth, left and right during the working process can be avoided.

[0022] 2. For the concrete point-compacting device and its using method described in the present invention, after the compacting work is completed, wind up the sling through the winch to drive the hanging frame to rise and pull out the vibrating rod from the concrete. Move the hanging frame away from above the formwork by controlling the vehicle body. Then, open the cleaning pipe through the control valve, and the clear water in the water tank flows downward through the cleaning pipe to wash the surface of the vibrating rod, removing the concrete adhered to its surface, without manual washing, preventing the problem that the concrete dries and hardens on the surface of the vibrating rod, resulting in poor subsequent vibration effect.

Specific embodiments

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] Embodiment 1

[0035] As Figures 1 to 4As shown in the figure, a concrete point compaction device according to an embodiment of the present invention includes a vehicle body 1; an extension beam 2 is fixedly connected to the top of the vehicle body 1; a winch is arranged inside the vehicle body 1; a sling 3 is connected to the surface of the winch, and the other end of the sling 3 passes through the top of the extension beam 2 and is fixedly connected to a suspension frame 4; a support plate 5 is fixedly connected to the top of the extension beam 2; a group of guide rods 6 are fixedly connected to the upper side of the suspension frame 4, and the guide rods 6 penetrate through the support plate 5 and are slidably connected thereto; a sliding seat 7 is slidably connected inside the suspension frame 4; a first motor 8 is fixedly connected to one side of the suspension frame 4; a screw rod 9 is fixedly connected to the surface of the output shaft of the first motor 8, and the screw rod 9 is rotatably connected to the suspension frame 4; the screw rod 9 penetrates through the sliding seat 7 and is connected thereto through a screw-nut pair; two groups of elastic vibrating rods 10 are evenly distributed on the lower side of the sliding seat 7; a guide plate 11 is fixedly connected between each group of the vibrating rods 10; a second motor 12 is fixedly connected to the surface of the sliding seat 7 between the two groups of the vibrating rods 10; a turntable 13 is fixedly connected to the surface of the output shaft of the second motor 12; a group of knocking rods 14 are evenly distributed on the circumference of the side surface of the turntable 13; Although the concrete point compaction device in the prior art can reduce the labor intensity of workers, the support plate of the device is connected to the support device through a steel cable, so that the support plate of the device is prone to shaking back and forth, left and right during use, resulting in a decrease in stability during work, and a plurality of rows of evenly arranged vibrating rods 10 are provided to achieve uniform and comprehensive compaction, which increases the construction cost and is not conducive to meeting the actual use requirements; At this time, when the present invention is working, the suspension frame 4 is moved above the concrete formwork by controlling the vehicle body 1, and the sling 3 is wound and released by the winch, and then the suspension frame 4 descends and the vibrating rods 10 are inserted into the concrete inside the formwork. Then, the second motor 12 is started to drive the turntable 13 to rotate, so that the knocking rods 14 intermittently knock the guide plate 11, prompting the vibrating rods 10 to vibrate. After that, the screw rod 9 is driven by the first motor 8 to rotate forward and reverse intermittently, driving the sliding seat 7 to reciprocate inside the suspension frame 4, so that the vibrating rods 10 translate and move around inside the concrete to compact the concrete at points, improving the compaction degree of the concrete. Since the vibrating rods 10 are arranged to be movable, the number of vibrating rods 10 can be reduced, the construction cost can be reduced, and the suspension frame 4 can be limited by arranging the guide rods 6 to avoid the problem of shaking back and forth, left and right of the suspension frame 4 during work.

[0036] An installation groove is formed at the end of the knocking rod 14 away from the turntable 13; a guide wheel 15 is rotatably connected to the inside of the installation groove through a rotating pin; By arranging the guide wheel 15, when the knocking rod 14 moves to the guide plate 11, the guide wheel 15 contacts the guide plate 11 and rolls on its surface, thereby reducing the resistance and wear between the knocking rod 14 and the guide plate 11 and extending the service life of the device.

[0037] A water tank 16 is fixedly connected to the upper side of the sliding seat 7, and clean water is added inside the water tank 16; a cleaning pipe 17 is fixedly connected to the lower side of the sliding seat 7 near the vibrating rod 10, and the cleaning pipe 17 is communicated with the water tank 16 through a control valve 18; after the compaction work is completed, the hoist is used to wind up the sling 3, driving the hanging frame 4 to rise and pulling out the vibrating rod 10 from the concrete, moving the hanging frame 4 away from above the formwork through the control of the vehicle body 1, and then opening the cleaning pipe 17 through the control valve 18. The clean water in the water tank 16 flows downward through the cleaning pipe 17 to wash the surface of the vibrating rod 10 and remove the concrete adhered to its surface, without manual washing, preventing the problem that the concrete dries and hardens on the surface of the vibrating rod 10, resulting in poor subsequent vibration effect.

[0038] A movable ring 19 is slidably connected to the outer side of the vibrating rod 10; an annular groove is formed on the upper side of the movable ring 19; an elastic rope 20 is fixedly connected between the movable ring 19 and the lower side of the sliding seat 7; after the cleaning pipe 17 is opened, under the impact of the water flow, the movable ring 19 will move downward and stretch the elastic rope 20, and then the scraping ring will further scrape the concrete on the surface of the vibrating rod 10 downward, improving the cleaning efficiency of the vibrating rod 10. After the cleaning pipe 17 is closed, the elastic rope 20 pulls the movable ring 19 to rise and reset.

[0039] There is a gap between the bottom of the movable ring 19 and the vibrating rod 10; by setting the gap, after the water flow enters the inside of the movable ring 19, it can flow downward along the gap between the movable ring 19 and the vibrating rod 10, so that the movable ring 19 scrapes the larger pieces of concrete on the surface of the vibrating rod 10 while washing the vibrating rod 10, and the water inside the movable ring 19 can be emptied through the gap after the cleaning pipe 17 is closed, preventing waste of water, and at the same time minimizing the weight of the movable ring 19, so that the subsequent elastic rope 20 can smoothly pull the movable ring 19 to reset.

[0040] A water collecting ring 21 is fixedly connected to the edge of the upper side of the movable ring 19; the water collecting ring 21 is arranged in a trumpet shape, and the diameter of the top of the water collecting ring 21 is larger than the diameter of the bottom; by setting the water collecting ring 21, the splashing water droplets can be collected, so that the water droplets flow into the inside of the movable ring 19 along the inclined surface of the water collecting ring 21 for washing the surface of the vibrating rod 10, further reducing water waste.

[0041] Embodiment 2

[0042] As Figures 5 to 7As shown, compared with the first comparative example, another implementation of the present invention is as follows: A group of film coatings 22 are evenly distributed on the inner circumference of the movable ring 19; an elastic block 23 is fixedly connected in the closed cavity formed between the film coating 22 and the inner side of the movable ring 19, and the elastic block 23 is made of a water-absorbing material; a group of bent pipes 24 are evenly distributed on the outer circumference of the movable ring 19; the upper end of the bent pipe 24 communicates with the closed cavity, and the lower end of the bent pipe 24 extends below the movable ring 19 and inclines upward; water collecting ports 25 are provided on the upper and lower sides of the film coating 22; a first magnetic block 26 is fixedly connected to the side of the film coating 22 close to the vibrating rod 10; a second magnetic block 27 is fixedly connected inside the lower end of the vibrating rod 10, and the first magnetic block 26 and the second magnetic block 27 repel each other when approaching; the water inside the movable ring 19 will enter the film coating 22 through the water collecting ports 25 and be absorbed by the elastic block 23, making the inside of the elastic block 23 full of moisture. When the movable ring 19 moves to the bottom of the vibrating rod 10, the second magnetic block 27 will generate a repulsive force on the first magnetic block 26. Then, the first magnetic block 26 squeezes the elastic block 23 through the film coating 22, squeezing out the moisture inside the elastic block 23. The squeezed water enters the inside of the bent pipe 24 and is sprayed obliquely upward through the lower end of the bent pipe 24 to wash the bottom end face of the vibrating rod 10, so that the residual concrete on the end face of the vibrating rod 10 can also be cleaned up, further improving the cleaning degree of the vibrating rod 10.

[0043] An elastic cap 28 is fixedly connected to the side of the film coating 22 close to the vibrating rod 10, and the concave surface of the elastic cap 28 faces the film coating 22; by providing the elastic cap 28, when the first magnetic block 26 drives the film coating 22 and the elastic cap 28 to move toward the inner side of the movable ring 19, the elastic cap 28 can be buckled on the inner surface of the movable ring 19, thereby blocking the water collecting ports 25, so that most of the moisture inside the elastic block 23 can enter the inside of the bent pipe 24 when the elastic block 23 is squeezed, improving the utilization rate of water, and thus more fully washing the end face of the vibrating rod 10.

[0044] A slider 29 is slidably connected inside the lower end of the bent pipe 24; a group of guide holes 30 are evenly distributed inside the slider 29; an elastic rope two 31 is fixedly connected between the side of the slider 29 away from the vibrating rod 10 and the inner side of the bent pipe 24; a group of brush hairs 32 are evenly distributed on the side of the slider 29 close to the vibrating rod 10; after the water flow enters the inside of the bent pipe 24, since the diameter of the guide holes 30 is small and the water flow is too late to flow out through the guide holes 30 completely, the water flow will push the slider 29 to move outward, driving the brush hairs 32 to extend outward and stab the bottom section of the vibrating rod 10, further cleaning the relatively stubborn concrete on the end face of the vibrating rod 10. At the same time, the water flow is sprayed out synchronously through the guide holes 30, and the small guide holes 30 can increase the water flow pressure, improving the cleaning efficiency of the end face of the vibrating rod 10.

[0045] As Figure 8As shown, a method for using a concrete point compaction device, which uses the above-mentioned concrete point compaction device, includes the following steps:

[0046] S1: Control the vehicle body 1 to move the suspension frame 4 above the concrete formwork, and reel the suspension cable 3 through the winch, so that the suspension frame 4 descends and inserts the vibrating rod 10 into the concrete inside the formwork;

[0047] S2: Start the second motor 12 to drive the turntable 13 to rotate, and the knocking rod 14 intermittently knocks the guiding plate 11 to cause the vibrating rod 10 to vibrate. Then, drive the screw rod 9 to rotate forward and reverse intermittently through the first motor 8, so that the vibrating rod 10 moves horizontally in the concrete to compact the concrete at points;

[0048] S3: Reel in the suspension cable 3 through the winch to drive the suspension frame 4 to rise and pull out the vibrating rod 10 from the concrete. Control the vehicle body 1 to move the suspension frame 4 away from above the formwork. Then, open the cleaning pipe 17 by the control valve 18, and the clear water in the water tank 16 flows downward through the cleaning pipe 17 to wash the surface of the vibrating rod 10.

[0049] Working principle: By controlling the vehicle body 1, the suspension frame 4 is moved above the concrete formwork, and the hoisting rope 3 is wound and released by the winch. Then, the suspension frame 4 descends and the vibrating rod 10 is inserted into the concrete inside the formwork. Next, the second motor 12 is started to drive the turntable 13 to rotate, causing the knocking rod 14 to intermittently knock on the guiding plate 11, prompting the vibrating rod 10 to vibrate. After that, the first motor 8 drives the screw rod 9 to rotate forward and reverse intermittently, driving the sliding seat 7 to reciprocate inside the suspension frame 4, enabling the vibrating rod 10 to translate and move around inside the concrete, compacting the concrete at different points, and improving the compaction degree of the concrete. Since the vibrating rod 10 is set to be movable, the number of vibrating rods 10 can be reduced, lowering the construction cost. And by setting the guide rod 6 to limit the suspension frame 4, the problem of the suspension frame 4 shaking left and right, front and back during the working process can be avoided; by setting the guide wheel 15, when the knocking rod 14 moves to the guiding plate 11, the guide wheel 15 contacts and rolls on the surface of the guiding plate 11, thereby reducing the resistance and wear between the knocking rod 14 and the guiding plate 11, and prolonging the service life of the device; after the compaction work is completed, the hoisting rope 3 is wound up by the winch, driving the suspension frame 4 to rise and pulling the vibrating rod 10 out of the concrete. By controlling the vehicle body 1, the suspension frame 4 is moved away from above the formwork. Then, the cleaning pipe 17 is opened through the control valve 18, and the clear water in the water tank 16 flows downward through the cleaning pipe 17 to wash the surface of the vibrating rod 10, removing the concrete adhered to its surface, without the need for manual washing, preventing the concrete from drying and hardening on the surface of the vibrating rod 10, resulting in poor subsequent vibration effects; after the cleaning pipe 17 is opened, under the impact of the water flow, the movable ring 19 will move downward and stretch the first elastic rope 20, and then the scraping ring will further scrape the concrete on the surface of the vibrating rod 10 downward, improving the cleaning efficiency of the vibrating rod 10. After the cleaning pipe 17 is closed, the first elastic rope 20 pulls the movable ring 19 to rise and reset; by setting the gap, after the water flow enters the inside of the movable ring 19, it can flow downward along the gap between the movable ring 19 and the vibrating rod 10, enabling the movable ring 19 to scrape the larger pieces of concrete on the surface of the vibrating rod 10 while washing the vibrating rod 10, and the water inside the movable ring 19 can be emptied through the gap after the cleaning pipe 17 is closed, preventing water waste, and at the same time minimizing the weight of the movable ring 19, enabling the subsequent first elastic rope 20 to smoothly pull the movable ring 19 back to its original position; by setting the water collecting ring 21, the splashing water droplets can be collected, enabling the water droplets to flow into the inside of the movable ring 19 along the inclined surface of the water collecting ring 21 for washing the surface of the vibrating rod 10, further reducing water waste;The water inside the movable ring 19 will enter the film covering 22 through the water collecting port 25 and be absorbed by the elastic block 23, making the inside of the elastic block 23 full of moisture. When the movable ring 19 moves to the bottom of the vibrating rod 10, the second magnet 27 will generate a repulsive force on the first magnet 26. Then, the first magnet 26 squeezes the elastic block 23 through the film covering 22, squeezing out the water inside the elastic block 23. The squeezed-out water enters the inside of the elbow pipe 24 and sprays obliquely upward through the lower end of the elbow pipe 24 to wash the bottom end face of the vibrating rod 10, so that the residual concrete on the end face of the vibrating rod 10 can also be cleaned up together, further improving the cleaning degree of the vibrating rod 10; by setting the elastic cap 28, when the first magnet 26 drives the film covering 22 and the elastic cap 28 to move towards the inside of the movable ring 19, the elastic cap 28 can buckle on the inner surface of the movable ring 19, thereby blocking the water collecting port 25, so that most of the water inside the elastic block 23 can enter the inside of the elbow pipe 24 when the elastic block 23 is squeezed, improving the utilization rate of water, and thus more fully washing the end face of the vibrating rod 10; after the water flow enters the inside of the elbow pipe 24, since the diameter of the guide hole 30 is small and the water flow is too late to flow out through the guide hole 30, the water flow will push the slider 29 to move outwards, driving the brush bristles 32 to stretch outwards and pierce the bottom section of the vibrating rod 10, further cleaning the relatively stubborn concrete on the end face of the vibrating rod 10. At the same time, the water flow is sprayed out synchronously through the guide hole 30, and the small guide hole 30 can increase the water flow pressure, improving the cleaning efficiency of the end face of the vibrating rod 10.;
