The invention discloses an anti-fatigue boom assembly of a pump truck and the pump truck, relates to the field of engineering machinery, and aims to reduce the probability of cracking of a bracket for fixing a material conveying pipe. The pump truck anti-fatigue arm support assembly comprises an arm support, a support, a material conveying pipe and a reinforcing ring. The arm frame is constructed to be box-shaped; the arm frame is provided with a mounting hole; one end of the bracket is inserted into a mounting hole of the boom, and the other end of the bracket is positioned on the outer side of the boom; the support comprises a first through hole. The material conveying pipe is fixed to the other end of the support. The reinforcing ring is installed in the first through hole of the support and is in interference fit with the inner wall of the first through hole. The reinforcing ring comprises a second through hole; the reinforcing ring, the bracket and the arm frame form a multi-layer structure from inside to outside; the reinforcing ring is configured to reinforce the stent inside the stent. According to the technical scheme, the external space of the arm support and the support does not need to be occupied, the reinforcing ring is installed in the support, and the strength of the connecting position of the arm support and the support is enhanced through the reinforcing ring.

本发明公开了一种泵车抗疲劳臂架组件以及泵车，涉及工程机械领域，用以减少用于固定物料输送管的支架出现开裂现象的几率。泵车抗疲劳臂架组件包括臂架、支架、物料输送管以及加强环。臂架被构造为箱型的；臂架设置有安装孔；支架的一端插入臂架的安装孔内，支架的另一端位于臂架的外侧；支架包括第一通孔。物料输送管固定于支架的另一端。加强环安装于支架的第一通孔中，且与第一通孔的内壁过盈配合；加强环包括第二通孔；加强环、支架、臂架形成由内至外的多层结构；加强环被构造为在支架的内部对支架起到加强作用。上述技术方案，不需要占用臂架和支架的外部空间，而是在支架内部安装加强环，通过加强环对臂架和支架连接处的强度起到加强作用。
