[0001] The invention relates to the technical field of construction engineering, in particular to a pile driving device for construction engineering. Background Art

[0002] Engineering construction refers to the general term for various buildings and engineering facilities that provide the material and technical basis for human life and production. It includes construction projects, pipelines and equipment installation projects, etc. It is an organized, purposeful, large-scale economic activity of mankind.

The fixed plate is retracted to the top of the bottom plate to improve its convenience when moving. The hydraulic rod is started to push the disc to move downward.

When the extrusion ring moves closer to each other, it will impact the lower surface of the pile body. When the pile body is tilted, the extrusion ring will adjust the angle of the pile body through the impact. The extrusion ring is semicircular, and the ends of the extrusion ring will approach each other when one end approaches each other. At the same time, the ends of the extrusion ring will squeeze the inclined pile body when in contact, thereby improving the stability of the pile body during the piling operation. The motor is started to drive the rotating rod to rotate. When the rotating rod rotates, the threaded rod is mobilized to rotate. The position of the screw hole frame is adjusted by the threaded rod to adjust the moving distance of the extrusion ring.

[0013] The reset spring of the present invention utilizes elasticity to push the telescopic rod to extend outward. When the telescopic rod is extended, it pushes the positioning plates to move closer to each other and contact each other. The positioning plates are utilized to squeeze and limit the pile body, thereby improving the stability of the pile body during the piling operation. The positioning plates are located at one end of the extrusion rings that are close to each other, thereby preventing the pile body from tilting when the extrusion rings are separated.

When the pile driving rod 14 of the present invention moves downward, the lifting rod 29 is pushed to slide on the surface of the vertical rod 16 through the synchronous rod 23. When the lifting rod 29 moves, the connection between the elastic frame 21 and the inclined plate 26 pushes the extrusion ring 25 to move closer to each other. When the extrusion ring 25 moves, it pushes the sleeve rod 24 to slide on the surface of the moving rod 27, thereby improving the stability of the extrusion ring 25 when moving. When the extrusion ring 25 moves closer to each other, it will impact the lower surface of the pile body. When the pile body is tilted, the extrusion ring 25 will adjust the angle of the pile body by impact, and the extrusion ring 25 will adjust the angle of the pile body by impact. The ring 25 is semicircular, and the ends of the extrusion ring 25 will approach each other when one end approaches each other. At the same time, the ends of the extrusion ring 25 will squeeze the inclined pile body when in contact, thereby improving the stability of the pile body during piling operations.
