The invention discloses a design of a 400t hydraulic climbing locking mechanism, which belongs to the field of large hoisting equipment and comprises two phi 300 double-acting main oil cylinders, a jacking concave plate, an upper group of anchorage devices, a lower group of anchorage devices, a balance valve group, square steel and the like. Two main oil cylinders of the 400t hydraulic climbing locking mechanism are arranged in an inverted mode (movable rods face downwards), one side of a piston rod of the 400t hydraulic climbing locking mechanism is connected with the lower anchor through a bolt, and one side of a cylinder barrel of each main oil cylinder of the 400t hydraulic climbing locking mechanism is connected with the upper anchor through a bolt. Each set of anchorage device of the 400t hydraulic climbing locking mechanism is provided with two wedge-shaped blocks used for grasping square steel, the inclined faces of the wedge-shaped blocks of the 400t hydraulic climbing locking mechanism are in sliding fit with the inclined faces of the anchorage blocks, and reset springs are installed on the lower end faces of the wedge-shaped blocks of the 400t hydraulic climbing locking mechanism. The opening and closing actions of the wedge block of the 400t hydraulic climbing locking mechanism are controlled by a small oil cylinder of the anchorage device, a piston of the small oil cylinder extends out, the wedge block is opened, the piston retracts, and the wedge block is closed.

    本发明公开一种400t液压爬升锁死机构设计,属于大型吊装起重设备领域,机构由两个φ300双作用的主油缸、顶升凹板、上下两组锚具、平衡阀组、方钢等部分组成。所述400t液压爬升锁死机构的两个主油缸为倒装形式(活寨杆朝下),所述400t液压爬升锁死机构活塞杆的一侧通过螺栓与下错连接,所述400t液压爬升锁死机构主油缸缸筒的一侧通过的螺栓与上锚连接。所述400t液压爬升锁死机构每组锚具都配有2个用于抓紧方钢的楔形块,所述400t液压爬升锁死机构楔形块的斜面与锚块的斜面为滑动配合,所述400t液压爬升锁死机构楔块下端面装有复位弹簧,所述400t液压爬升锁死机构楔块的打开和关闭动作由锚具小油缸控制,小油缸活塞伸出,打开楔块,活塞回缩,楔块关闭。
