Description

Technical Field

[0001] This utility model relates to the field of concrete vibration, specifically a splash-proof device for concrete vibration. Background Technology

[0002] Concrete poured into the formwork needs to be vibrated to ensure its compactness, reduce the occurrence of honeycomb and pitting after drying, and ensure the density and structural strength of the concrete. The most common concrete vibration method currently used is the internal vibrator, which inserts the vibrator into the concrete and vibrates it continuously to quickly remove air bubbles and achieve a compact and uniform effect. However, when using the vibrator, concrete can easily be splashed onto the surrounding building structure or the operators, affecting the cleanliness of the building structure and resulting in a dirty and messy working environment. Utility Model Content

[0003] The purpose of this utility model is to provide a splash-proof device for concrete vibration, which can solve the impact of concrete splashing on the surrounding environment and operators, effectively seal and protect the vibration position, prevent concrete from splashing outwards, and ensure the cleanliness of the building structure and operating environment.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A splash-proof device for concrete vibration includes a protective cover fitted over the outside of a vibrating rod. The top of the protective cover has an upper opening. A connecting pipe is provided on the vibrating rod. Contact wheels are symmetrically rotatably connected to the upper opening. The contact wheels on both sides roll into contact with the two sides of the connecting pipe. A support ring is slidably connected to the bottom of the protective cover vertically. A spring is provided between the protective cover and the support ring. Multiple fixing seats are arrayed at the bottom of the support ring.

[0006] Furthermore, the top of the support ring is provided with a groove, the bottom of the protective cover is slidably connected in the groove, and the spring is disposed between the bottom of the protective cover and the bottom of the groove.

[0007] Furthermore, the fixing base is provided with a fixing plate, and the bottom of the fixing plate is provided with a lower magnetic block.

[0008] Furthermore, the longitudinal section of the fixed base is L-shaped, the fixed plate is rotatably connected to the fixed base, the top of the fixed plate is provided with an upper magnetic block, the cross section of the upper magnetic block is arc-shaped, and when the fixed plate is rotated to the vertical position, the upper magnetic block magnetically attracts the side wall of the support ring.

[0009] Furthermore, a fixed frame and a movable frame are provided at the upper ring opening. The fixed frame is fixedly connected to the upper ring opening, and the movable frame is slidably connected to the upper ring opening. The contact wheels on both sides are respectively rotatably arranged at opposite ends of the fixed frame and the movable frame. The protective cover is provided with an operating rod that drives the movable frame to slide laterally.

[0010] Furthermore, an outer support is provided on the outside of the protective cover, the operating rod passes through the outer support and is threadedly connected to it, and the end of the operating rod is rotatably connected to the movable frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model features a protective cover on the outside of the vibrating rod to protect the vibration area, effectively preventing concrete splashing at the vibration location and ensuring the cleanliness of the building structure and operating environment. Furthermore, an upper ring is provided at the top of the protective cover, with symmetrically arranged contact wheels at the upper ring. The contact wheels on both sides roll into contact with the sides of the connecting pipe on the vibrating rod. This structure allows the connecting pipe to contact the contact wheels at the upper ring when the vibrating rod and connecting pipe pass through the upper ring into the interior of the protective cover. The rolling contact wheels support the connecting pipe, preventing bending damage to the connecting pipe when the top of the protective cover contacts it. This ensures the integrity of the vibration device and the continuity of the vibration operation while preventing concrete splashing.

[0013] 2. A support ring is vertically slidable at the bottom of the protective cover. The support ring is placed on the reinforcing cage at the top of the concrete formwork. A spring is installed between the protective cover and the support ring. This structure prevents the protective cover, which contacts the connecting pipe, from directly contacting the bottom reinforcing cage, thus avoiding the direct transmission of continuous vibration to the reinforcing cage and causing significant noise. Instead, the protective cover contacts the support ring on the reinforcing cage through the spring, thereby reducing the intensity of vibration and noise. Multiple fixing seats are provided at the bottom of the support ring, making the support ring fit more firmly against the reinforcing cage and further ensuring the stability of the splash-proof device.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] Reference Figure 1 and Figure 2This utility model describes a splash-proof device for concrete vibration. The main structure includes a protective cover 2 fitted over the vibrator 1. The protective cover 2 is made of metal or plastic and has a narrower top and wider bottom structure. It protects the area vibrated by the vibrator 1 from concrete splashing onto surrounding buildings or workers, ensuring the cleanliness of the building structure and operating environment. The top of the protective cover 2 has an upper opening 3 through which the vibrator 1 enters the interior of the protective cover 2. The vibrator 1 is equipped with a connecting pipe 4, which connects to... The vibrating device is connected to achieve continuous vibration of the vibrating rod 1. Contact wheels 5 are symmetrically connected to the upper ring opening 3 via bearings. The contact wheels 5 on both sides roll into contact with the sides of the connecting pipe 4. This structure ensures that when the vibrating rod 1 and connecting pipe 4 pass through the upper ring opening 3 and enter the protective cover 2 for vibration operation, the connecting pipe 4 contacts the contact wheels 5 on both sides of the upper ring opening 3. This prevents bending damage to the connecting pipe 4 caused by the top of the protective cover 2, ensuring the integrity of the connecting pipe 4 and guaranteeing both splash protection and... To ensure the integrity of the vibration device and the continuity of the vibration operation, a support ring 6 is vertically slidably connected to the bottom of the protective cover 2. The support ring 6 is placed on the reinforcing cage at the top of the concrete formwork to provide support. A spring 7 is provided between the protective cover 2 and the support ring 6. The spring 7 is used to elastically connect the protective cover 2 and the support ring 6. Since the protective cover 2 is in direct contact with the connecting pipe 4, it will also generate continuous vibration. The spring 7 slows down the vibration of the protective cover 2 and transmits it to the support ring 6, so that the vibration amplitude and frequency of the support ring 6 are reduced before being transmitted to the reinforcing cage. Therefore, the vibration intensity can be greatly reduced, and the resulting noise intensity is greatly reduced. Of course, relying solely on the spring 7 cannot effectively avoid noise. A sound-absorbing pad can also be placed at the bottom of the support ring 6. The sound-absorbing pad is in direct contact with the reinforcing cage, thereby further reducing the vibration noise. Multiple fixing seats 8 are arrayed at the bottom of the support ring 6. The fixing seats 8 further increase the contact area between the bottom of the support ring 6 and the reinforcing cage, improving the stability of the splash-proof device placed on the reinforcing cage.

[0022] Preferred, refer to Figure 3 The top of the support ring 6 is provided with a groove 9, which is recessed downward from the top of the support ring 6. The bottom of the protective cover 2 is slidably connected in the groove 9. The spring 7 is disposed between the bottom of the protective cover 2 and the bottom of the groove 9. The bottom of the protective cover 2 is set as an annular shape, and the annular part is slidably connected in the groove 9 vertically. This arrangement allows the protective cover 2 to accurately contact the springs 7 at various positions when it vibrates up and down, thereby effectively reducing the frequency and amplitude of the vibration and improving the noise reduction effect.

[0023] Preferably, the fixing seat 8 is provided with a fixing plate 10, and the bottom of the fixing plate 10 is fixed with a lower magnetic block 11 by welding or bolts. The lower magnetic block 11 is magnetically attracted to the reinforcing cage, so that the fixing seat 8 and the support ring 6 maintain a firm contact with the reinforcing cage, avoid the position of the protective cover 2 changing during the vibration process, and further improve the stability of the vibration structure.

[0024] Preferably, the longitudinal section of the fixing base 8 is L-shaped, and the fixing plate 10 is rotatably connected to the corner of the L-shaped fixing base 8 by a pin or hinge. The top of the fixing plate 10 is fixed with an upper magnetic block 12 by welding or bolts. The cross-section of the upper magnetic block 12 is arc-shaped. When the fixing plate 10 is rotated to the vertical position, the upper magnetic block 12 magnetically attracts the side wall of the support ring 6. With this structure, when not in use, the fixing plate 10 can be rotated to contact the vertical part of the L-shaped fixing base 8, and the arc-shaped upper magnetic block 12 at the top of the fixing plate 10 magnetically attracts the side wall of the support ring 6, thus effectively storing the fixing plate 10. When in use, it can be rotated to the horizontal position to contact the horizontal part of the L-shaped fixing base 8, so that the lower magnetic block 11 magnetically attracts the reinforcing cage, improving the stability during use and further improving the convenience of storage and use of the device.

[0025] Preferred, refer to Figure 4 The upper ring opening 3 is provided with a fixed frame 13 and a movable frame 14. The fixed frame 13 is fixedly connected to the upper ring opening 3 by welding or bolts, and the movable frame 14 is slidably connected to the upper ring opening 3. Specifically, a through sliding hole is provided on the side wall of the upper ring opening 3, and the movable frame 14 passes through the sliding hole and is slidably connected to it. The contact wheels 5 on both sides are respectively rotatably set on the opposite ends of the fixed frame 13 and the movable frame 14 through bearings. The protective cover 2 is provided with an operating rod 15 for driving the movable frame 14 to slide laterally. This structure allows the movable frame 14 to slide outward when the vibrator 1 and the connecting pipe 4 are inserted, leaving space for the insertion of the vibrator 1 and the connecting pipe 4. After the vibrator 1 is inserted into the concrete, the movable frame 14 slides in the opposite direction, so that the contact wheel 5 at the end of the movable frame 14 contacts the side wall of the connecting pipe 4, clamping and fixing the connecting pipe 4 between the contact wheels 5 on both sides, so that the connecting pipe 4 maintains stability during vibration, and is not prone to large-scale shaking of the connecting pipe 4, thus ensuring the firmness of the vibration structure.

[0026] Preferably, an outer bracket 16 is fixed to the outside of the protective cover 2 by welding or bolts. The operating rod 15 passes through the outer bracket 16 and is threadedly connected to it. The end of the operating rod 15 is rotatably connected to the movable frame 14 through a bearing. With this structure, the movable frame 14 can be driven to slide relative to the protective cover 2 by rotating the operating rod 15 under the action of the threaded connection. The threaded connection also maintains the stability of the sliding position, further simplifying the operation steps and improving the convenience and stability of the sliding structure of the movable frame 14.

[0027] Working Principle: This invention features a protective cover 2 on the outside of the vibrator 1, protecting the vibration area of ​​the vibrator 1 and effectively preventing concrete splattering at the vibration location, thus ensuring the cleanliness of the building structure and operating environment. An upper ring 3 is provided at the top of the protective cover 2, with contact wheels 5 symmetrically arranged at the upper ring 3. The contact wheels 5 on both sides roll into contact with the two sides of the connecting pipe 4 on the vibrator 1. This structure allows the connecting pipe 4 to contact the contact wheels 5 at the upper ring 3 when the vibrator 1 and connecting pipe 4 pass through the upper ring 3 into the interior of the protective cover 2. The rolling contact wheels 5 support the connecting pipe 4, preventing bending damage to the connecting pipe 4 when the top of the protective cover 2 contacts it. While avoiding concrete splashing, the integrity of the vibrating device is ensured, guaranteeing the continuity of the vibration operation. A support ring 6 is vertically slidably installed at the bottom of the protective cover 2, and the support ring 6 is placed on the reinforcing cage at the top of the concrete formwork. A spring 7 is installed between the protective cover 2 and the support ring 6. This structure prevents the protective cover 2, which contacts the connecting pipe 4, from directly contacting the bottom reinforcing cage, thus avoiding the direct transmission of continuous vibration to the reinforcing cage and causing significant noise. Instead, the vibration intensity is reduced by the contact between the support ring 6 and the spring 7 on the reinforcing cage. Multiple fixing seats 8 are provided at the bottom of the support ring 6, making the support ring 6 more firmly attached to the reinforcing cage, further ensuring the stability of the splash-proof device.
