Pump truck arm support and pump truck
The invention discloses a pump truck arm support and a pump truck, relates to the field of engineering machinery, and aims to enable the structure of the pump truck arm support to be more compact and reasonable. The pump truck arm frame comprises a first arm frame, a second arm frame and a worm and gear driving mechanism. And the second arm frame is rotatably connected with the first arm frame. The worm gear and worm driving mechanism comprises a worm gear and a worm which are meshed with each other; the worm gear comprises an inner ring and an outer ring which are rotatably connected; the inner ring is fixedly connected with the first arm support, and the outer ring is fixedly connected with the second arm support. According to the pump truck arm frame provided by the technical scheme, the worm and gear driving mechanism is adopted to drive the first arm frame and the second arm frame to rotate relatively, and the worm and gear driving mechanism has a reverse self-locking characteristic and can realize mechanical self-locking, so that the first arm frame can be safely and reliably stopped at any position relative to the second arm frame. In addition, the worm and gear driving mechanism has a large transmission ratio, the structure is compact, and the weight is low; and the meshed tooth surfaces of the two gears are in linear contact, so that the bearing capacity is high.
本发明公开了一种泵车臂架以及泵车，涉及工程机械领域，用以使得泵车臂架的结构更加紧凑、合理。泵车臂架包括第一臂架、第二臂架以及蜗轮蜗杆驱动机构。第二臂架与第一臂架可转动连接。蜗轮蜗杆驱动机构包括相互啮合的蜗轮以及蜗杆，蜗轮包括可转动连接的内圈和外圈；内圈与第一臂架固定连接，外圈与第二臂架固定连接。上述技术方案提供的泵车臂架，其采用蜗轮蜗杆驱动机构来驱动第一臂架和第二臂架相对转动，蜗轮蜗杆驱动机构具有反向自锁特性，可以实现机械自锁，使得第一臂架相对于第二臂架可以安全可靠地停止在任意位置。并且，蜗轮蜗杆驱动机构具有很大的传动比，结构紧凑，重量低；两轮啮合齿面间为线接触，承载能力大。
