Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing.

[0041] An embodiment of the rolling wheel of the road roller in the present invention is as Figure 1~Figure 3 As shown, it includes an outer drum 10, a spoke plate 20, a support shaft 30 and a road roller excitation device 60. The axial ends of the support shaft 30 are provided with double-row cylindrical roller bearings 40, and the radial outer side of the web plate 20 is fixed on the outer drum. 10, the radial inner side of the web 20 cooperates with the cylindrical roller bearing 40, and the web 20 is also provided with a bearing cover 50 that cooperates with the cylindrical roller bearing 40 in the axial direction, so that the outer cylinder 10 Rotationally fitted on the support shaft 30 .

[0042] The roller exciter device 60 includes a device frame 61, a coil barrel 62, a counterweight impact block 65 and a coil magnetic field control device. The device frame 61 is...

Abstract

The invention relates to a road roller vibration device, a road roller rolling wheel and a road roller. The road roller vibration device comprises a device frame used for being fixedly connected with a supporting shaft of the road roller rolling wheel. Balance weight impacting blocks movably arranged in the vertical direction and drive devices used for driving the balance weight impacting blocks to move up and down in the vertical direction are arranged on the device frame. The device frame is further provided with an impacted portion used for bearing downward impact of the balance weight impacting blocks. Compared with the prior art, the dynamic mass of the road roller is larger than the static mass through motion and impact of the balance weight impacting blocks, energy counteracted by two eccentric blocks does not exist, so that the energy use rate can be effectively increased, the structure is simple, the manufacturing cost is low, and reliability is good.

Description

technical field [0001] The invention relates to a road roller vibration device, a road roller rolling wheel and a road roller. Background technique [0002] The road roller is a method that uses mechanical weight, vibration or impact to repeatedly load the compacted material, overcome the cohesion and internal friction between the materials, remove the gas and moisture inside, and force the displacement between the material particles. , Wedging each other, increasing the compactness, so that it can reach a certain degree of compactness and flatness, widely used in the compaction of basic construction projects such as roads, railway subgrades, airport runways, embankments, and building foundations. [0003] The road roller in the prior art, such as the road roller disclosed in the Chinese patent whose authorized announcement number is CN 102691248 B, is a vibratory road roller, comprising a road roller and an excitation device arranged in the road roller. The wheel includes ...
