Embodiment Construction
[0032] The accompanying drawings disclose, without limitation, the structural schematic diagrams of the preferred embodiments involved in the present invention; the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] like image 3 , 4 As shown, the centering and vibration-absorbing device of the present invention is connected between the outer wall of the delivery pipe and the inner wall of the connecting pipe, and includes a cage and a shock absorber. The cage is a hollow member, and the wall of the cage is radially opened. There are more than three vibration-damping positioning holes, and each vibration-damping positioning hole is equipped with a vibration-damping part with a vibration-damping function. Surface, the second arc surface matched with the inner wall of the connecting pipe; the distance between the first arc surface and the second arc surface of the shock absorber is greater than t...

The invention discloses a centering vibration damping device and a concrete pump truck conveying pipe assembly with the centering vibration damping function; the centering vibration damping device is connected between the outer wall of the conveying pipe and the inner wall of the connecting pipe, and includes a cage and The vibration damping part, the cage is a hollow member, and the wall of the cage is provided with more than three vibration damping positioning holes in the radial direction, and each vibration damping positioning hole is equipped with a vibration damping part with a vibration damping function. The vibrating part has two arc surfaces, which are the first arc surface matched with the outer wall of the delivery pipe and the second arc surface matched with the inner wall of the connecting pipe; The distance between them is greater than the depth of the vibration-damping positioning holes. It can be seen that the present invention greatly reduces the fatigue damage of the supporting structure of the conveying pipe and the supporting structure of the components installed on the connecting pipe; at the same time, it also improves the safety, convenience and accuracy of the cloth, and reduces the labor cost during construction.
Description
technical field [0001] The invention relates to a centering and vibration damping device, which is used for alleviating the impact transmitted from the conveying pipe and the conveying pipe to the connecting pipe, and reducing the fatigue damage of the supporting structure of the conveying pipe and the supporting structure of other components installed on the connecting pipe. At the same time, the The shock absorber has a centering function. [0002] The invention relates to a delivery pipe assembly of a concrete pump truck with the function of centering and damping vibration, and belongs to the field of concrete pump truck production and manufacturing. Background technique [0003] At present, there are two types of concrete pump trucks on the market, one of which is not equipped with a vibration damping device for the delivery pipe. Therefore, when the concrete pump truck is pumping, especially at the turntable, it is difficult to Many, fast, pumping shock is large, the i...
