Abstract
The utility model relates to a pile gripper special for a concrete pre-cast pile. The pile gripper special for the concrete pre-cast pile comprises a hydraulic control driving mechanism, a clamp performing mechanism, a mounting support and a casing. A detachable outer cover arranged on the hydraulic control driving mechanism is served as the casing. A concave-convex-shaped friction surface is arranged on the inner clamping surface of a pile embracing plate. A large contact area is arranged between the pile embracing plate and the concrete pre-cast pile. The clamp performing mechanism is provided with functions of converting applying force direction, buffering clamping and automatically responding and releasing the concrete pre-cast pile and capable of reliably converting vertical thrust of axial movement to pushing force which can drive the pile embracing plate to do radial movement and is thrown evenly and horizontally on the concrete pre-cast pile, and therefore appressed contact and reliable clamp between the pile embracing plate and the concrete pre-cast pile are ensured. The concrete pre-cast pile is forced evenly and stress is increased or decreased slowly, and therefore destructive impact, sudden release and breaking or cracking of the concrete pre-cast pile in work process are avoided. Security and reliability of work and construction quality and progress are ensured, and practicability is strong.
Description
Technical field
