Pile driving hydraulic clamping hammer applicable to plates

Abstract

The invention discloses a pile driving hydraulic clamping hammer applicable to plates. The pile driving hydraulic clamping hammer comprises a connecting portion and a hydraulic clamping hammer. The hydraulic clamping hammer is mounted on the lower side of the connecting portion; the hydraulic clamping hammer comprises an upper connecting plate; an upper support plate is formed in the center of thelower end surface of the upper connecting plate; a pair of cylindrical rotary central columns which are symmetrically arranged in the left-right directions are fixed onto the upper support plate; a lower support plate is formed at the lower ends of the pair of rotary central columns; clamping jaws sleeve the pair of rotary central columns; the pair of clamping jaws is symmetrically arranged in the left-right directions; clamp support portions which are relatively far away from bent protrusions are formed in the middles of the fronts of the pair of clamping jaws; clamp hydraulic cylinders aremounted on the end surfaces, which are far away from each other, of the pair of clamp support portions; piston rods of the clamp hydraulic cylinders penetrate the clamp support portions, and clamp support blocks are hinged to the piston rods; clamping support blocks are arranged on opposite end surfaces of the front ends of the pair of clamping jaws. The pile driving hydraulic clamping hammer hasthe advantages that the pile driving hydraulic clamping hammer is applicable to clamping the plates, the side edges of the plates can be clamped by the pile driving hydraulic clamping hammer, and theproblem that the hoisting heights need to be increased to allow clamping hammers to adapt to piles can be solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic hammers, in particular to a piling hydraulic clamping hammer suitable for plate materials. Background technique [0002] In the existing hydraulic pile driving equipment, the clamping device of the bottom fixed fixture is usually used to clamp the object to be driven into the ground. The activities are free to connect, and it is difficult to operate during the pile clamping and lifting process, and the verticality of the pile cannot be guaranteed. The height of the pile is greatly restricted by the volume of the auxiliary main engine. Positioning, poor safety performance. [0003] In addition, for specific forms of objects that need to be driven into the ground, such as plates, due to their specific shapes, they are usually stacked together before use, which makes it difficult to clamp, and they need to be manually or otherwise stood on their sides during clamping or partially overhead.
