Centrifugal vibrating rod easy to control

Abstract

The invention relates to the technical field of concrete equipment, and discloses a centrifugal vibrating rod easy to control. The centrifugal vibrating rod easy to control comprises a vibrating rod shell, a flexible shaft and a shaft connector, the lower end of the shaft connector is in transmission connection with an adjustable rotation shaft, and a limiting block is fixedly connected to the upper end of the outer side wall of the adjustable rotation shaft. According to the centrifugal vibrating rod easy to control, the relative positions between centrifugal blocks and a hinge rod are controlled through a driving rod, and then vibration output is controlled; as quite a long operation time is needed for vibrating rod transferring in the actual engineering operation, the centrifugal blocksare close to the hinge rod in the transferring process, vibration output is reduced, therefore, wear is reduced, the service life of the vibrating rod is prolonged, and meanwhile noise output is reduced; and when the vibrating rod is inserted into concrete, the output vibration magnitude can be appropriately adjusted, influences of the vibrating rod on the concrete in the sinking process are morecontrollable, especially when the inserting position is located at the corners or is close to steel bars, and then the vibrating quality of the concrete is improved.

technical field [0001] The invention relates to the technical field of concrete equipment, in particular to an easy-to-control centrifugal vibrating rod. Background technique [0002] see figure 1 When pouring concrete components, a vibrator must be used to remove the air bubbles and tamp them to make the concrete densely combined and eliminate the phenomenon of concrete honeycomb denseness. The vibration principle of the vibrating rod has eccentric type and planetary type. The rotating shaft with eccentric mass rotates at high speed, and the centrifugal force that changes direction is transmitted to the vibration shell through the bearing, thereby generating vibration. However, in this way, a large friction force will be generated between the bearing and the vibration shell, and its service life is limited.

Problems solved by technology

[0002] see figure 1 When pouring concrete components, a vibrator must be used to remove the air bubbles and tamp them to make the concrete densely combined and eliminate the phenomenon of concrete honeycomb denseness. The vibration principle of the vibrating rod has eccentric type and planetary type. The rotating shaft with eccentric mass rotates at high speed, and the centrifugal force that changes direction is transmitted to the vibration shell through the bearing, thereby generating vibration. However, in this way, a large friction force will be generated between the bearing and the vibration shell, and its service life is limited.

[0003] Secondly, the current construction site has high requirements for noise, and when the vibrating rod vibrates, it will generate a lot of noise, especially when the vibrating rod is pulled out from the concrete, the sound is particularly loud, and when the row-type vibrating rod is pulled out, Since the vibration frequency is the same, the noise will be further increased due to resonance, making it difficult for the construction project to meet environmental protection requirements

[0004] Also, when using a vibrator, first of all, the vibrating rod needs to sink into the concrete naturally, and it cannot be pushed down violently. When the vibrating rod sinks too slowly, the upper layer of concrete will be vibrated first, and the lower layer of concrete will vibrate first. Delamination occurs, especially when the viscosity of the concrete is high, its sinking speed is slow, and the final concrete quality may not meet the actual needs
