The invention discloses a concrete pump truck. The pump truck comprises a truck head, an arm frame is arranged on the upper portion of the right side of the truck head, the arm frame is fixed on a chassis, a feeding hopper is fixed to the right side above the chassis, the lower portion of the arm frame is fixed to a rotating box, a buffering device is arranged below the rotating box, and a first connecting rod is fixed on the outer side of the buffering device; and a first supporting leg is fixed to the outer side of the first connecting rod, a second supporting leg is fixed below the first supporting leg, third supporting legs are symmetrically fixed on the two sides of the second supporting leg below the first supporting leg, and a control box is fixed on the inner side of the lower portion of the first supporting leg. According to the concrete pump truck, as the center of gravity of the arm frame moves in the using process, the third supporting legs support the corresponding positions again, so that the situation that the ground collapses due to the fact that one supporting leg exerts too large pressure on the ground is prevented; and the buffering device can reduce vibration generated in the working process of the arm frame on the pump vehicle, abrasion of a sealing member in an oil cylinder is reduced, and the phenomenon of oil leakage of the oil cylinder caused by shakingof the arm frame is avoided.
本发明公开了一种混凝土泵车，该泵车包括车头，车头右侧上部设置臂架，臂架固定在底盘上，底盘上方右侧固定进料斗，臂架下方固定在转动箱上，转动箱下方设置缓冲装置，缓冲装置外侧固定第一连接杆；第一连接杆外侧固定第一支撑腿，第一支撑腿下方固定第二支撑腿，第一支撑腿下方第二支撑腿的两侧对称固定第三支撑腿，第一支撑腿下部内侧固定控制箱，本发明在使用过程中随着臂架重心的移动，第三支撑腿对相应位置进行再次支撑，防止一个支撑腿对地面施加压强过大，使地面塌陷的情况，缓冲装置可以减小泵车上的臂架在工作过程中产生的震动，减小油缸内密封件的磨损，避免油缸因臂架抖动所产生的漏油现象。
