Description

Technical Field

[0001] This utility model belongs to the technical field of concrete vibration equipment, and in particular relates to an auxiliary device for secondary vibration of large-volume concrete. Background Technology

[0002] Immersion vibrators include high-frequency immersion vibrators, which vibrate by inserting into the concrete. They are suitable for deep and large-area pouring, effectively remove air bubbles and compact the structure, and can be used to assist in the secondary vibration of large-volume concrete.

[0003] After use, the vibrating head of a conventional immersion vibrator, including a high-frequency immersion vibrator, will have a small amount of concrete residue adhering to its surface. If it is not cleaned in time, it will be difficult to remove after the concrete on the surface has hardened. Cleaning with external tools is also quite troublesome. This makes cleaning the vibrating head of a conventional immersion vibrator, including a high-frequency immersion vibrator, quite troublesome.

[0004] To address this issue, we propose a secondary vibration auxiliary device for large-volume concrete to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the cumbersome cleaning of the vibrating head of conventional immersion vibrators, including high-frequency immersion vibrators, and to propose a secondary vibration auxiliary device for large-volume concrete.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A secondary vibration auxiliary device for large-volume concrete includes a cable and an immersion vibrator head. The cable is connected to the upper end of the immersion vibrator head. A ring-shaped scraper is slidably mounted on the outside of the immersion vibrator head. A spring clip is fixedly connected to the upper end of the immersion vibrator head, and the upper part of the spring clip engages with the upper part of the immersion vibrator head. After the immersion vibrator head is placed in the target concrete, the spring clip is released, the ring scraper is pulled down, and then the ring scraper is pushed back up. The ring scraper cleans the residual concrete on the surface of the immersion vibrator head, preventing a large amount of concrete from solidifying outside the immersion vibrator head and facilitating quick and easy cleaning of residual concrete outside the immersion vibrator head.

[0007] Preferably, the vibrating head of the insert vibrator includes a housing, and a fastening ring is fixedly connected to the upper part of the housing. A spring-loaded buckle engages with the fastening ring, and the spring-loaded buckle acts on the annular scraper, keeping the annular scraper on the vibrating head of the insert vibrator, thus facilitating the maintenance of the annular scraper's position.

[0008] Preferably, the annular scraper includes a movable ring, with annular shovels fixedly connected to both the upper and lower parts of the movable ring. The movable ring and annular shovels are movably fitted onto the outer casing. Pulling the movable ring downwards or pushing it upwards causes the annular shovels to act on residual concrete outside the vibrating head of the immersion vibrator, facilitating quick and easy cleaning of residual concrete.

[0009] Preferably, the annular scraper further includes a handle, which is fixedly connected to the outside of the movable ring and to the inner end of the handle. Pulling the handle actuates the movable ring, which in turn acts on the annular scraper, causing the scraper to remove residual concrete along the outer shell.

[0010] Preferably, the spring clip includes a spring piece, the upper end of which is fixedly connected to a clip block, and the lower end of which is fixedly connected to a ring shovel. The spring piece's elasticity holds the clip block on the fastening ring, and the spring piece acts on the ring shovel, keeping the ring scraper on the vibrating head of the insert vibrator, thus facilitating the maintenance of the ring scraper's position.

[0011] Preferably, the snap-on mechanism further includes a pull button, which is fixedly connected to the upper part of the snap spring. Squeezing the pull button applies force to the upper part of the snap spring, pulling it outward to disengage the snap block from the fastening ring, thus facilitating the unlocking of the snap-on mechanism.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. After the vibrating head of the immersion vibrator is placed into the target concrete, release the spring clip, pull down the ring scraper, and then push the ring scraper back up. Use the ring scraper to clean the residual concrete on the outside of the vibrating head of the immersion vibrator, so as to avoid a large amount of concrete solidifying on the outside of the vibrating head of the immersion vibrator and facilitate quick cleaning of the residual concrete on the outside of the vibrating head of the immersion vibrator.

[0013] 2. The spring clips and fastening rings are used to fasten the ring scraper. The spring clips act on the ring scraper to keep the ring scraper on the vibrating head of the insert vibrator, making it easy to maintain the position of the ring scraper.

[0014] 3. Pull down or push up the movable ring to apply the ring shovel to the residual concrete outside the vibrating head of the immersion vibrator, making it easy and quick to clean up the residual concrete.

[0015] 4. The elasticity of the spring clip keeps the buckle block on the buckling ring. The spring clip acts on the ring scraper, keeping the ring scraper on the vibrating head of the insert vibrator, making it easy to maintain the position of the ring scraper. Attached Figure Description
