Pile hammer sleeve limiting device easy to assemble and disassemble
The invention discloses a pile hammer sleeve limiting device easy to assemble and disassemble. The device comprises a hammer sleeve; one end of the hammer sleeve is connected with a pile hammer, and the other end of the hammer sleeve is used for being connected with a steel pipe pile in a sleeved mode; eight sets of limiting device bodies are arranged on the inner wall of the hammer sleeve; each limiting device body comprises two fixed clamping plates and a movable clamping plate; the two fixed clamping plates are symmetrically welded to the inner wall of the hammer sleeve; each movable clamping plate is arranged in a gap between the corresponding two fixed clamping plates; grooves are formed in the upper ends of the fixed clamping plates; convex ribs are arranged on the movable clamping plates; the movable clamping plates are supported on the fixed clamping plates through matching of the convex ribs and the grooves; and the fixed clamping plates and the movable clamping plates are limited and fixed through fixing bolts. Compared with an existing method for welding rib plates in the hammer sleeve, only the movable clamping plates need to be replaced for steel pipe piles of different sizes, the construction efficiency is effectively improved, the working time is shortened, a large number of steel plate materials are saved, and the irreversible loss damage to a hammer sleeve base material due to repeated shoveling and welding is avoided.
本发明公开了一种易装卸的打桩锤套限位装置，包括锤套，锤套的一端与打桩锤连接，锤套的另一端用于套接钢管桩，在锤套的内壁上设置有8套限位装置，限位装置包括两块固定卡板和活动卡板，两块固定卡板对称地焊接在锤套的内壁上，活动卡板置于两块固定卡板之间的间隙内，在固定卡板的上端设置有凹槽，活动卡板上设有凸筋，通过凸筋与凹槽相配合，将活动卡板承托在固定卡板上，固定卡板与活动卡板之间通过固定螺栓限位固定。与现有的在锤套内部焊接筋板的方法相比，本发明针对不同尺寸的钢管桩仅需更换活动卡板即可，有效地提高施工效率，缩短工时，并且节省了大量钢板材料以及避免了反复铲除和焊接对锤套母材造成不可逆的损失破坏。
