Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically a concrete vibration device. Background Technology

[0002] A vibratory compactor is a construction device that uses mechanical vibration to eliminate air bubbles inside concrete and increase its density. It mainly consists of a power source and vibration transmission components. It is widely used in the vibration operation after concrete pouring in construction projects and can effectively improve the strength and durability of components.

[0003] When the vibrating device is working, the vibrating component comes into contact with the concrete and transmits the vibration energy in the form of waves to the surroundings. This reduces the internal friction and cohesion between the concrete particles, causing the particles to be in a liquefied or plastic flow state. Air bubbles in the concrete float to the surface and are expelled under the action of vibration. At the same time, the aggregate particles rearrange themselves under the action of gravity, filling the gaps and achieving compaction.

[0004] Cement adheres to the surface of vibrating components for a long time. After solidification, it will increase the diameter of the vibrating components and the surface roughness, which will increase the resistance when inserted into the concrete and lead to a decrease in vibration efficiency. Therefore, a concrete vibrating device is proposed to address the above problems. Utility Model Content

At the same time, the expansion plate can play a positioning role when the vibrating rod is inserted into the concrete, reducing the tilt of the vibrating rod and increasing the accuracy of its vibration position.

[0007] Preferably, the bottom of the expansion plate is fixedly connected to multiple protective tubes; the protective tubes are hexagonal; the bottom of the protective tubes is fixedly connected to a connecting ring; by installing a protective tube around the vibrator, a buffer layer can be formed, reducing the direct contact between the vibrator and the steel reinforcement in the concrete during vibration, reducing the peeling of the concrete protective layer on the surface of the steel reinforcement due to the high-frequency vibration of the vibrator, thereby reducing the risk of steel reinforcement corrosion and increasing the durability of the building structure. The hexagonal design makes the force on each side of the protective tube uniform, reducing the lateral pressure of the concrete and the squeezing of the steel reinforcement during vibration, and reducing the external impact on the vibrator.

[0010] Preferably, the bottom of the vibrating rod is threaded with a bolt; an eccentric counterweight ring is threaded between the bolt and the vibrating rod; by moving the eccentric counterweight ring to different distances and then fixing it with bolts, the magnitude of the centrifugal force generated by the internal rotation of the vibrating rod can be changed, thereby adjusting the vibration intensity, reducing energy damage, accelerating the speed at which cement paste coats aggregate, increasing the amount of air bubbles discharged, and increasing the compressive strength and impermeability of building components.

[0011] Preferably, a shock-absorbing sleeve is fixedly attached to the surface of the connecting hose; the shock-absorbing sleeve is in contact with the expansion plate; by installing a shock-absorbing sleeve at the connection between the expansion plate and the connecting hose, the vibration of the vibrator can be reduced to be transmitted to the operator's hand, reducing the risk of finger numbness caused by long-term work and thus increasing the operator's work efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 2 As shown in the embodiment of this utility model, a concrete vibration device includes a vibrating rod 1; a connecting hose 11 is installed on the top of the vibrating rod 1; a controller 12 is fixedly connected to the end of the connecting hose 11; a power cord 13 is fixedly connected to the bottom of the controller 12; the power cord 13 is connected to a power source; an expansion disc 14 is fixedly connected to the top of the vibrating rod 1; the expansion disc 14 is disposed between the vibrating rod 1 and the connecting hose 11; an elastic clamp 15 is fixedly connected to one side of the expansion disc 14; a scraper ring 16 is slidably connected to the surface of the vibrating rod 1; the end of the scraper ring 16 is inclined; a handle 17 is fixedly connected to one side of the scraper ring 16; the handle 17 and the elastic clamp 15 are correspondingly arranged; during operation, the power cord 13 is connected to the power source, and then the controller 12 is turned on to control the vibrating rod 1 to vibrate, the vibrating rod 1 is inserted into the concrete to perform vibration work, and after the vibration is completed, the vibrating rod 1 is removed from the concrete. Pull out rod 1, turn off controller 12 to stop vibrating rod 1, then push handle 17 to separate it from elastic clip 15. Continue pushing handle 17 to drive scraper ring 16 to slide on the surface of vibrating rod 1, scraping away the cement adhering to the surface of vibrating rod 1 along the inclined surface of scraper ring 16. After use, push handle 17 to contact elastic clip 15. When pushing, elastic clip 15 will elastically deform to both sides. After handle 17 enters, it will return to its original shape, thus fixing handle 17. After the vibration work is completed, push handle 17 to drive scraper ring 16 to slide on the surface of vibrating rod 1. The inclined surface scrapes away the cement adhering to the surface of vibrating rod 1, reducing the difficulty of cleaning after cement solidification, reducing manual maintenance workload, and increasing the service life of vibrating rod 1. At the same time, expansion disc 14 can play a positioning role when vibrating rod 1 is inserted into concrete, reducing the tilt of vibrating rod 1 and increasing the accuracy of its vibration position.

[0025] like Figure 1 and Figure 3As shown, multiple protective tubes 2 are fixedly connected to the bottom of the expansion plate 14; the protective tubes 2 are hexagonal; a connecting ring 21 is fixedly connected to the bottom of the protective tubes 2; during operation, when the vibrator 1 is vibrating, the multiple protective tubes 2 surround the vibrator 1, reducing concrete segregation caused by direct collision between the vibrator 1 and the steel bars in the concrete. The connecting ring 21 connects the multiple protective tubes 2 to increase the stability between the protective tubes 2. By installing a ring of protective tubes 2 around the vibrator 1, a buffer layer can be formed, reducing direct contact between the vibrator 1 and the steel bars in the concrete during vibration, reducing the peeling of the concrete protective layer on the surface of the steel bars due to the high-frequency vibration of the vibrator 1, thereby reducing the risk of steel bar corrosion and increasing the durability of the building structure. The hexagonal design makes the force on each side of the protective tube 2 uniform, reducing the lateral pressure of the concrete and the squeezing of the steel bars during vibration, and reducing the external impact on the vibrator 1.

[0026] like Figures 1 to 4 As shown, a water inlet pipe 3 is fixedly connected to one side of the expansion plate 14; the end of the water inlet pipe 3 is threaded; multiple water outlet pipes 31 are installed on the surface of the protective pipe 2; the protective pipe 2 has a cavity in the middle; the water outlet pipes 31 and the water inlet pipe 3 are connected; during operation, the end of the water inlet pipe 3 is threaded to a water pump, and then the water flow is sent into the cavity of the expansion plate 14 through the water pump, and sprayed out from the multiple water outlet pipes 31 to clean the surface of the vibrating rod 1. By connecting the water inlet pipe 3 to a water pump, the water flow passes through the expansion plate 14 and is sprayed out from the multiple water outlet pipes 31, covering the surface of the vibrating rod 1, reducing the solidification of cement on the surface of the vibrating rod 1, reducing the difficulty of cleaning the scraper ring 16, and increasing the cleaning efficiency.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, a flat head 4 is installed on the surface of the water outlet pipe 31; the flat head 4 is connected to the water outlet pipe 31; the flat head 4 and the water outlet pipe 31 are correspondingly arranged; during operation, when the vibrator 1 is inserted into the concrete for vibration, the flat head 4 reduces the entry of solid particles in the concrete into the water outlet pipe 31, preventing blockage. By setting the flat head 4 at the end of the water outlet pipe 31, a filter barrier can be formed, reducing the entry of large solid particles such as gravel and sand in the concrete into the water outlet pipe 31, which would lead to poor water flow or even complete blockage of the water outlet pipe 31. This increases the continuous effectiveness of the cleaning function of the water outlet pipe 31, reduces downtime maintenance time, and increases the cleaning stability of the water outlet pipe 31.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, the bottom of the vibrating rod 1 is threaded with a bolt 51; an eccentric counterweight ring 5 is threaded between the bolt 51 and the vibrating rod 1; during operation, the eccentric counterweight ring 5 is moved to a specified eccentric distance, and then the bolt 51 is passed through the eccentric counterweight ring 5 and the bottom of the vibrating rod 1 for fixation. By moving the eccentric counterweight ring 5 to different distances and then fixing it with the bolt 51, the magnitude of the centrifugal force generated by the internal rotation of the vibrating rod 1 can be changed, thereby adjusting the vibration intensity, reducing energy damage, accelerating the speed at which cement paste coats aggregate, increasing the amount of air bubbles discharged, and increasing the compressive strength and impermeability of building components.

[0029] like Figure 1 As shown, a shock-absorbing sleeve 6 is fixedly attached to the surface of the connecting hose 11; the shock-absorbing sleeve 6 is in contact with the expansion plate 14; during operation, the shock-absorbing sleeve 6 is wrapped around the connection between the top of the expansion plate 14 and the connecting hose 11, and the operator holds the shock-absorbing sleeve 6 to move the vibrator 1 for vibration work. By installing the shock-absorbing sleeve 6 at the connection between the expansion plate 14 and the connecting hose 11, the vibration of the vibrator 1 can be reduced to be transmitted to the operator's hand, reducing the risk of numbness in the fingers caused by long-term work and thus reducing the risk of operational errors, and increasing the operator's work efficiency.

[0030] Working principle: By connecting the power cord 13 to the power supply, the controller 12 is turned on to control the vibrator 1 to vibrate. The vibrator 1 is inserted into the concrete for vibration. After vibration, the vibrator 1 is pulled out, and the controller 12 is turned off to stop the vibration. Then, the handle 17 is pushed to separate it from the elastic clip 15. Pushing the handle 17 further causes the scraper ring 16 to slide on the surface of the vibrator 1, scraping away the cement adhering to the surface of the vibrator 1 along the inclined surface of the scraper ring 16. After use, the handle 17 is pushed until it contacts the elastic clip 15. When pushed further, the elastic clip 15 elastically deforms to both sides and returns to its original shape after the handle 17 is inserted, thus fixing the handle 17. During the vibration of the vibrator 1, multiple protective tubes 2 surround the vibrator 1. To reduce concrete segregation caused by direct collision between the vibrator 1 and the reinforcing steel in the concrete, the connecting ring 21 connects multiple protective pipes 2 to increase the stability between the protective pipes 2. The end of the water inlet pipe 3 is threaded to a water pump, and then the water flow is sent through the water pump into the cavity of the expansion plate 14 and sprayed out from multiple water outlet pipes 31 to clean the surface of the vibrator 1. When the vibrator 1 is inserted into the concrete for vibration, the flat head 4 reduces the entry of solid particles in the concrete into the water outlet pipe 31, which may cause blockage. The eccentric counterweight ring 5 is moved to the specified eccentric distance, and then the bolt 51 is passed through the eccentric counterweight ring 5 and the bottom of the vibrator 1 for fixation. The shock-absorbing sleeve 6 is wrapped at the connection between the top of the expansion plate 14 and the connecting hose 11. The operator holds the shock-absorbing sleeve 6 and moves the vibrator 1 to perform vibration work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
