Description

Technical Field

[0001] The invention relates to the technical field of bridge pier manufacturing, in particular to a bridge pier column concrete vibrating device with a mechanical arm guide structure. Background Art

[0002] Vibrating bridge pier concrete is a critical process in bridge construction, crucial for its structural quality and durability. Proper selection and use of vibrating equipment is crucial to ensure dense, honeycomb-free, and void-free concrete. Insert vibrators or attached vibrators are typically used, with the appropriate vibration method selected based on the size and shape of the pier. During the vibration process, the concrete should be vibrated evenly to avoid missed or over-vibration. The vibration time should be determined based on the concrete's consistency and the vibrator's power, typically stopping when the concrete surface no longer significantly sinks, exhibits slurry buildup, and stops bubbling. Furthermore, vibration should be performed continuously to avoid stratification caused by initial setting. During construction, relevant construction specifications and safety procedures should be followed to ensure quality and personnel safety.

[0003] When forming bridge piers, the existing vibrating device needs to vibrate the concrete in the pier mold. The existing vibrating device is a vibrating rod inserted into the concrete for vibration. However, due to the large size of the pier mold, the vibrating rod needs to be moved back and forth during vibration to vibrate the concrete in the mold in all directions, resulting in uneven vibration effects of the concrete in different parts during the vibration process. In particular, the concrete is constantly deposited and solidified during the vibration process, and the vibration effects of concrete vibrated at different times are different.

The design of the robotic arm's guide structure enables the vibrating rod to vibrate according to a predetermined path and depth, thereby effectively avoiding the phenomenon of missed vibration or over-vibration that occurs in traditional vibration methods.

[0017] 3. When the sliding sleeve of the present application descends, it drives the connecting block to descend, and when the sliding sleeve descends, it drives the moving ball to descend. When the moving ball descends inside the sleeve, it pushes multiple protrusions to descend. When the multiple protrusions descend, they drive multiple clamping balls to descend and push the multiple clamping balls to move to both sides. When the clamping balls and the sliding rods on both sides move to both sides, the multiple clamping balls vibrate under the push of the moving balls, thereby improving the vibration effect. When the moving ball descends, it drives the bevel tooth plate to descend, which pushes the vibrating tooth plates on both sides to vibrate, thereby improving the vibration effect, vibrating the concrete in the center, and improving the uniformity of concrete vibration.
