Detailed Description

In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to examples, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, a structural schematic diagram of an embodiment of the vibratory pile hammer integrating feeding, turning, clamping and pile sinking is shown, wherein a hoisting steel wire rope is arranged at the top of the vibratory pile hammer, and the vibratory pile hammer can only move under the action of a hoisting force and cannot turn over.

The connecting frame is arranged at the bottom of the vibrating pile hammer; one end of the transition overturning frame is connected with the connecting frame through a fixed rotating shaft, the other end of the transition overturning frame is movably connected with the connecting frame through a pin shaft oil cylinder, and after the pin shaft oil cylinder is disconnected, the transition overturning frame can overturn along the direction of the fixed rotating shaft; the bottom of the transition roll-over stand is provided with a plurality of internal bracing type fixtures for clamping and bracing the steel pile pipe, and the internal bracing type fixtures move along with the transition roll-over stand.

Further, referring to fig. 2 and 3, the invention realizes the integrated operation of feeding, turning, clamping and pile sinking through the following steps.

Firstly, a transitional overturning frame and a connecting frame form a fixed hinge support connection through a fixed rotating shaft; when the transition roll-over stand is parallel to the connecting stand, the transition roll-over stand and the connecting stand can be fixed by extending the piston rod of the pin roll oil cylinder; when a piston rod pin shaft of the pin shaft oil cylinder is in a retraction state, the transition roll-over stand and the internal support type clamp can freely turn over around the fixed rotating shaft.

When a piston rod pin shaft of the pin shaft oil cylinder is in a retraction state, the overturning thrust oil cylinder extends out of the piston rod, and the extension length is adjusted to enable the internal support type clamp to be in a horizontal position.

The internal bracing type clamp is sleeved on the horizontally-lying steel pipe pile, and pile feeding action is completed in a horizontal state, so that special equipment required in pile feeding can be effectively omitted.

And opening the internal-supporting type clamp to clamp the steel pipe pile to finish the pile clamping action.

And pulling up the vibrating pile hammer to gradually change the steel pipe pile from the horizontal state to the vertical state.

When the pin roll oil cylinder is coaxial with the pin hole on the transition roll-over stand, the piston rod pin roll of the pin roll oil cylinder is extended out to fix the transition roll-over stand and the connecting frame, and the pile turning action is completed.

And moving the vibrating pile hammer to the pile position, and opening the vibrating pile hammer to finish the pile sinking action.

In summary, the vibratory pile hammer integrating feeding, turning, clamping and pile sinking provided by the invention can finish horizontal pile feeding, pile turning, pile clamping and pile sinking which originally need a plurality of special equipment through one piece of equipment, so that the working procedures are more continuous, and the required time can be reduced by about 90%.
