Description

Technical Field

[0001] This utility model relates to the technical field of asphalt concrete vibration devices, specifically an asphalt concrete vibration device for road construction. Background Technology

[0002] The asphalt concrete vibrating device is a core component of the asphalt paver's working device. It is mainly used to initially compact and level the asphalt mixture after paving, laying the foundation for subsequent screeding operations. Its structure typically includes key components such as a vibrating beam, eccentric shaft, and hydraulic drive system. It achieves the compaction of the mixture through high-frequency vibration, while pressing large aggregate particles into the pavement layer, improving the stability and durability of the road structure.

[0003] Traditional asphalt concrete vibrating devices typically vibrate at a single point. Single-point vibration can easily lead to local over-vibration or under-vibration, making it difficult to achieve large-scale, multi-dimensional synchronous vibration. This results in voids and segregation within the mixture, affecting the overall compaction. Utility Model Content

[0004] The purpose of this utility model is to provide an asphalt concrete vibration device for road construction, which solves the problem that traditional asphalt concrete vibration devices usually vibrate at a single point. Single-point vibration is prone to local over-vibration or under-vibration, making it difficult to achieve large-scale, multi-dimensional synchronous vibration, resulting in voids and segregation in the mixture, which affects the overall density.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an asphalt concrete vibration device for road construction, including a vibrator, a base fixedly installed on the lower surface of the vibrator, a connecting hose fixedly installed at the output end of the vibrator, a vibrating rod fixedly installed at one end of the connecting hose, an external thread on the outer surface of the vibrating rod, a vibration amplification mechanism threaded to the outer surface of the external thread, and the amplification end of the vibration amplification mechanism is located at one end of the vibrating rod.

[0007] Furthermore, the vibration amplification mechanism includes a threaded connecting pipe, which is threaded to the outer surface of the external thread, and several branch rods are fixedly installed on the circumferential side of the threaded connecting pipe.

[0008] Furthermore, a connecting ring is fixedly installed at one end of several of the branch rods, and a number of connecting springs are fixedly installed on the lower surface of the connecting ring;

[0009] Furthermore, a branch vibration rod is fixedly installed at one end of each connecting spring;

[0010] Furthermore, a sealing ring is fixedly installed at one end of the threaded connecting pipe, and the sealing ring abuts against the outer surface of the vibrating rod;

[0011] The external thread on the outer surface of the vibrator is fixedly connected to the threaded connecting pipe of the vibration amplification mechanism, transmitting the foundation vibration to the branch structure. Several branch rods around the threaded connecting pipe synchronously receive the main vibration source signal and drive the branch vibrator rod at the end to perform secondary high-frequency micro-amplitude vibration through the connecting ring and connecting spring. The spring design can buffer the impact and maintain dynamic balance, ensuring that each branch works independently and collaboratively, realizing simultaneous vibration of a large area and multiple dimensions, and significantly improving the density and smoothness of the asphalt mixture.

[0012] Furthermore, the outer surface of the connecting hose is fixedly fitted with Velcro;

[0013] The Velcro straps on the outside of the connecting hose allow it to be strapped to the worker's arm, thereby improving the worker's comfort when holding the connecting hose and reducing labor intensity.

[0014] This utility model has the following beneficial effects:

[0015] (1) The external thread on the outer surface of the vibrator of this utility model is connected and fixed to the threaded connecting pipe of the vibration expansion mechanism, so as to transmit the basic vibration to the branch structure. Several branch rods on the periphery of the threaded connecting pipe synchronously receive the main vibration source signal, and drive the branch vibration rod at the end of the connecting ring and the connecting spring to perform secondary high-frequency micro-amplitude vibration. The spring design can buffer the impact and maintain dynamic balance, ensuring that each branch works independently and collaboratively, realizing simultaneous vibration of large area and multiple dimensions, and significantly improving the density and smoothness of asphalt mixture.

[0016] (2) The Velcro on the outside of the connecting hose of this utility model can be used to tie the connecting hose to the worker's arm, thereby improving the worker's comfort when holding the connecting hose and reducing labor intensity.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The external thread 401 on the outer surface of the vibrator is threadedly connected and fixed to the threaded connecting pipe 501 of the vibration amplification mechanism 5, transmitting the foundation vibration to the branch structure. Several branch rods 502 on the periphery of the threaded connecting pipe synchronously receive the main vibration source signal and drive the branch vibration rod 505 at the end to perform secondary high-frequency micro-amplitude vibration through the connecting ring 503 and the connecting spring 504.
