Novel cantilever crane luffing mechanism and concrete pump truck with same
The invention relates to a novel cantilever crane luffing mechanism, the luffing mechanism is used for controlling unfolding and folding of a cantilever crane and comprises a rotary table, a first knuckle arm and a first knuckle arm oil cylinder, the first knuckle arm is hinged to the rotary table, one end of the first knuckle arm oil cylinder is hinged to the first knuckle arm, the novel cantilever crane luffing mechanism further comprises a supporting frame and a connecting rod, one end of the connecting rod is hinged to the first knuckle arm, the other end of the connecting rod is hinged tothe supporting frame, one end of the supporting frame is hinged to the rotary table, the other end of the supporting frame is hinged to the other end of the first knuckle arm oil cylinder, and the first knuckle arm oil cylinder is arranged above the first knuckle arm. According to the novel cantilever crane luffing mechanism, due to the fact that the first knuckle arm oil cylinder is arranged above the first knuckle arm, the problem that in the prior art, a first knuckle arm oil cylinder is arranged below a first knuckle arm, and consequently the length design of a second knuckle arm and thelength design of a third knuckle arm are limited is solved.
本发明涉及一种新型臂架变幅机构，用于控制臂架的展开与收回，包括转台、第一节臂与第一节臂油缸，所述第一节臂与所述转台铰接，所述第一节臂油缸的一端与所述第一节臂铰接，该臂架变幅机构还包括支撑架和连杆，所述连杆的一端与所述第一节臂铰接，所述连杆的另一端与所述支撑架铰接，所述支撑架的一端与所述转台铰接，所述支撑架的另一端与所述第一节臂油缸的另一端铰接，且所述第一节臂油缸设于所述第一节臂的上方。通过将第一节臂油缸设于所述第一节臂的上方，消除了现有技术采用第一节臂油缸设于第一节臂下方而对第二节臂以及第三节臂的长度设计带来限制的问题。
