AI Technical Summary

Technical Problem

Existing precast pile clamps cannot effectively clamp the precast piles when the oil cylinder leaks, causing safety hazards such as pile displacement, tilting or falling off.

Method used

The inclined surface and the first wedge block structure in the pile clamp are designed. The output force of the oil cylinder acts indirectly on the precast pile through the inclined surface. The friction between the wedge block and the inclined surface is used to enhance the clamping force. The wedge block can be moved to adapt to piles of different specifications. When the oil cylinder leaks, the clamping force is still increased to prevent the pile from shifting.

Benefits of technology

The clamping stability is improved, the potential safety hazards of pile displacement, tilting or falling are avoided, and the clamping force is enhanced without increasing the output force of the cylinder, simplifying the maintenance process.

Abstract

The utility model relates to a universal precast pile clamp which comprises a pile clamping frame, a pile clamping cavity is formed in the pile clamping frame in the axis direction of the pile clamping frame in a penetrating mode, a plurality of pile clamping mechanisms distributed at intervals are arranged in the pile clamping cavity, each pile clamping mechanism comprises an oil cylinder, and an inclined face is arranged in the pile clamping cavity. The inclined faces are distributed in the axis direction of the pile clamping frame, one end of each inclined face inclines towards one side of the central axis of the pile clamping frame, the oil cylinders are distributed above the inclined faces, first wedge-shaped blocks are hinged to the output ends of the oil cylinders, bodies of the oil cylinders are hinged to the pile clamping frame, and clamping positions capable of clamping precast piles are formed among the first wedge-shaped blocks. The size of the clamping position is changed by controlling the first wedge-shaped block to reciprocate on the inclined face through the oil cylinder. The universal precast pile clamp is suitable for clamping precast piles of different specifications and types, and the potential safety hazards that the precast piles shift, incline and even fall off are avoided.
