Description

Technical Field

[0001] This utility model relates to the field of concrete vibration technology, specifically to an intelligent vibration device for dam concrete pouring. Background Technology

[0002] During the concrete construction of the dam, concrete vibration is necessary during the pouring process. This is because, during concrete mixing, air bubbles and gaps easily form inside the concrete due to the viscosity of the cement paste and the shape and particle size of the aggregate. If these air bubbles and gaps are not removed in time, they will affect the strength and durability of the concrete. Concrete vibration allows the particles inside the concrete to rearrange, expelling air bubbles and pores, eliminating honeycomb and pitting phenomena, ensuring a dense bond, improving concrete strength, and guaranteeing the quality of the pouring.

[0003] The most common type of vibratory compaction machine is the vibratory rod. Its principle is to use an electric motor or internal combustion engine as a power source, driving an eccentric device inside the vibratory rod to rotate at high speed through a transmission system. This generates high-frequency vibrations within the concrete, removing air bubbles and making the concrete denser and more uniform. However, because the shape of the vibratory rod is fixed, it lacks operational flexibility in concrete pouring in confined spaces or complex structures, such as inside bridge piers of dams and bridges, shear walls of high-rise buildings, and in casting molds with curved shapes. It is difficult to precisely control the vibration position and range, easily leading to insufficient or excessive vibration.

[0004] Therefore, this utility model proposes an intelligent vibration compaction device for dam concrete pouring. Utility Model Content

[0009] Preferably, the slide cylinder and the connecting cylinder are connected by threads.

[0010] Preferably, the end of the deflector head is a pointed shape that tapers inward.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, an external control device retracts the electric telescopic rod, causing the protruding area of ​​the deflector head to tilt outside the connecting cylinder, thus tilting the overall shape of the connecting cylinder and the deflector head. Then, by driving a micro-motor to rotate a preset number of times, the turntable and the electric telescopic rod rotate, changing the upward tilt direction of the deflector head until its tilt angle matches the internal shape of the bending mold. Through precise control of the micro-motor and the electric telescopic rod in the rotating unit, the deflector head can tilt at any angle, allowing for precise control of the vibration position and range, reducing insufficient or excessive vibration, and improving the overall vibration quality of the concrete.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an intelligent vibration device for dam concrete pouring;

[0020] Example

[0021] It includes an electric motor 1, with a cable 2 at one end and electrically connected thereto. The end of the cable 2 is provided with a rod 3 and fixedly connected thereto. The rod 3 has an eccentric component inside that can rotate at high speed, thereby generating high-frequency vibration in the concrete. The above is the prior art, so it will not be described in detail.

[0022] In this design, the outer wall of the rod body 3 is provided with a sliding cylinder 4 and is slidably connected to it. The outer wall of the end of the sliding cylinder 4 is provided with a connecting cylinder 5. The sliding cylinder 4 and the connecting cylinder 5 are threadedly connected. The threaded connection makes it easy to disassemble the connecting cylinder 5 and the sliding cylinder 4 in time for maintenance and upkeep. The inside of the connecting cylinder 5 is provided with a deflecting head 6 and is movably connected to it. The protruding part of the deflecting head 6 can rotate freely in any direction outside the connecting cylinder 5. The end of the deflecting head 6 is shaped into an inwardly tapering sharp shape. The sharp shape of the end of the deflecting head 6 makes it easier for workers to insert it into a narrow vibration area, which is beneficial for vibration in narrow areas.

[0023] The connecting cylinder 5 is equipped with a rotating unit 7 that drives the deflector head 6 to tilt upward. By changing the tilt direction of the deflector head 6 through the rotating unit 7, the overall vibration area of ​​the rod body 3 is changed, which is more suitable for concrete pouring molds with local bending and reduces the situation of insufficient or excessive vibration.

[0024] The rotating unit 7 includes a connecting buckle 8 located at the end of the deflecting head 6. The bottom of the connecting buckle 8 is fixedly connected to the deflecting head 6. The connecting buckle 8 has a connecting head 9 inside. The connecting head 9 and the connecting buckle 8 are fitted together and the connecting head 9 can move freely. An electric telescopic rod 10 is provided above the connecting head 9 and is fixedly connected to it. The other end of the electric telescopic rod 10 has a turntable 11 and is fixedly connected to it. The turntable 11 is rotatably connected to the connecting cylinder 5. The electric telescopic rod 10 is electrically connected to an external control device, and the extension distance of the electric telescopic rod 10 can be controlled by the external control device. A micro motor 12 is provided above the turntable 11. The outer wall of the micro motor 12 is fixedly connected to the connecting cylinder 5. The rotating shaft of the micro motor 12 is located inside the turntable 11 and is fixedly connected to it. The micro motor 12 drives the turntable 11 to rotate. The micro motor 12 is electrically connected to an external control device, and the number of rotations of the micro motor 12 can be controlled by the external control device.

[0025] Working principle:

[0026] The vibration effect of the rod body 3 can be automatically transmitted to the outside, ultimately causing the slide cylinder 4, connecting cylinder 5, and deflector head 6 to all vibrate. After the operator inserts the deflector head 6 into a narrow, curved area, the electric telescopic rod 10 can be retracted via an external control device. This causes the end of the electric telescopic rod 10 to pull the connecting buckle 8. When the connecting buckle 8 at the end of the deflector head 6 is subjected to tension, it will cause the protruding area of ​​the deflector head 6 to tilt outside the connecting cylinder 5, thus making the overall shape of the connecting cylinder 5 and the deflector head 6 tilted. After this, the operator can drive the micro motor 12 to rotate a preset number of times via an external control device. During this process, the micro motor 12 will drive the turntable 11 and the electric telescopic rod 10 to rotate, which will also cause the upward tilting direction of the deflector head 6 to change until the tilting angle of the deflector head 6 is the same as the angle of the internal shape of the curved mold, making the vibrator suitable for precise vibration of narrow shapes.

[0027] By precisely controlling the data of the micro motor 12 and the electric telescopic rod 10 in the rotating unit 7, the deflection head 6 can be tilted at any angle, allowing the vibrator to accurately control the vibration position and range, reducing insufficient or excessive vibration, and improving the overall vibration quality of concrete.

[0028] In addition, the bottom end of the rod body 3 is equipped with an electric telescopic rod 13 and is fixedly connected to it. The bottom end of the electric telescopic rod 13 is fixedly connected to the slide cylinder 4, and the electric telescopic rod 13 is electrically connected to the external control equipment. The operator can also control the extension distance of the electric telescopic rod 13 through the external control equipment, thereby extending the descent distance of the slide cylinder 4, the connecting cylinder 5 and the deflection head 6, so as to be suitable for more complex and deeper vibration environments and ensure good vibration quality.
