Linear motor drive based pile driver without guide frame

Abstract

The invention discloses a linear motor drive based pile driver without a guide frame. The linear motor drive based pile driver is mainly used for construction preformed piles in the field of constructional engineering and high in pile driving efficiency and low in noise. The pile driver mainly comprises a driving device, a clamping device, a tracked vehicle, a suspension arm and a winch. An operating principle includes that the preformed piles horizontally put on the ground are clamped by the clamping device, then the winch lifts the driving device to make the preformed piles in a vertical state, the tracked vehicle moves to move the preformed piles to a pile driving station, then the driving device is started, when a linear motor stator of the driving device is connected with a positive power source, the linear motor stator moves linearly upwards and drives a hammering head to move linearly upwards, and when the linear motor stator of the driving device is connected with a reverse power source, the linear motor stator moves linearly downwards and drives a hammering head to move linearly downwards, so that the hammering head hammers the preformed piles under the repeated movement to drive the preformed piles into soil.

Description

technical field [0001] The invention is mainly used for construction prefabricated piles in the field of construction engineering. Background technique [0002] At present, the prefabricated pile pile drivers used in the field of construction engineering need to be equipped with piling device guide frames or guide rods, and at the same time, they need to be equipped with hoisting equipment to hoist the prefabricated piles to the piling station, and the traditional piling devices are not only heavy equipment, piling noise is large, Pile driving efficiency is not high either. Contents of the invention [0003] The present invention overcomes the above-mentioned defects. It does not require a guide frame for a piling device, nor does it need to be equipped with a hoisting device, and the piling device driven by a linear motor has high piling efficiency and low noise; it mainly includes a driving device (1), a clamping device ( 2), crawler vehicle (3), boom (4), hoist (5), wi...
