Problems solved by technology

[0002] At present, the working principle of pile drivers commonly used in construction projects is as follows: the pile hammer located at a high place hits the set pile under the action of gravity, and then the hoist lifts the pile hammer to reset it to complete the reciprocating motion; in addition to relying on its own In addition to power provided by gravity for the pile hammer, it can also be powered by diesel or hydraulic pressure. Without exception, the pile drivers of these structures need a hoist at the rear to lift the pile hammer to achieve reset. Caused a lot of inconvenience in project transportation

Embodiment

[0013] by figure 1 , figure 2 In the shown embodiment, the screw pile driver includes a cylindrical pile frame 1 and a pile hammer 2; A screw 3 extending along the axis is installed on the 1 axis, and the rotation of the screw 3 is driven by a driving motor; a screw hole 23 matching the screw 3 is provided along the axis of the pile hammer 2, and the pile hammer 2 The outer surface has ribs 21 matching the slots 11 on the inner wall of the pile frame 1 . A metal chain is used to connect a hard backing plate 4 at the bottom of the pile frame 1; an oil storage structure containing lubricating oil is arranged on the top of the screw rod 3 and the inner wall of the pile frame 1.

[0014] The pile hammer 2 is limited by the draw-in groove 11 of the pile frame 1 inner wall, and cannot rotate along the axis, but can only produce displacement in the vertical direction; during construction, start the drive motor, and the drive motor drives the screw mandrel 3 to accelerate rotation;...

Abstract

The invention relates to a lead screw pile driver. The lead screw pile driver comprises a cylinder pile rack and a pile hammer, wherein a snapping slot which axially extends along the pile rack is formed in the inner wall of the pile rack, a lead screw extending along an axis is assembled on the axis of the pile rack, the lead screw is driven by a motor to rotate, a screw hole matched with the lead screw is formed along an axis of the pile hammer, and a rib matched with the snapping slot in the inner wall of the pile rack is arranged on the outer surface of the pile hammer. Compared with traditional pile drivers, the lead screw pile driver has the advantages that the pile hammer can accomplish high-frequency pile hitting tasks with larger impact forces in smaller strokes, pile hitting speeds are obviously increased, and meanwhile, space of construction areas can be saved.

Description

technical field [0001] The invention relates to a pile driver. Background technique [0002] At present, the working principle of pile drivers commonly used in construction projects is as follows: the pile hammer located at a high place hits the set pile under the action of gravity, and then the hoist lifts the pile hammer to reset it to complete the reciprocating motion; in addition to relying on its own In addition to power provided by gravity for the pile hammer, it can also be powered by diesel or hydraulic pressure. Without exception, the pile drivers of these structures need a hoist at the rear to lift the pile hammer to achieve reset. Caused a lot of inconvenience in project transportation. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a screw pile driver, which can make the pile hammer complete the high-frequency piling task with a relatively large impact force in a small stroke, and significan...
