Pile driver based on transverse magnetic flux permanent magnet linear motor driving
The invention discloses a pile driver based on transverse flux permanent magnet linear motor driving. The pile driver comprises a crawler, a precast pile, a driving device, a guide rail, a hammering head, a hydraulic rod, a holding device, a stator iron core, an armature winding, a permanent magnet and a stator iron core. The hydraulic rod is fixed to the crawler and used for controlling the guide rail to move. The holding device is mounted at one end of the guide rail; the other end of the guide rail is used as a stator of the linear motor; the stator iron core and the plurality of groups of permanent magnets with the same shape and shape are arranged in the middle of the guide rail; the holding device is used for fixing the precast pile and enabling the precast pile to be in a vertical state; by means of the modulation effect between the permanent magnet and the stator iron core, the flux linkage in the armature winding is alternated, so that induced potential and electromagnetic force are generated, and the driving device is driven to move up and down along the guide rail. The piling machine is high in piling efficiency, low in noise and small in occupied area during use.
本发明公开了一种基于横向磁通永磁直线电机驱动的打桩机，包括：履带车、预制桩、驱动装置、导轨、锤击头、液压杆、抱持装置、定子铁心、电枢绕组、永磁体和定子铁心；所述履带车上固定有所述液压杆,所述液压杆用于控制所述导轨移动；所述导轨一端安装有所述抱持装置；所述导轨的另一端作为直线电机的定子；所述导轨的中间部分设有所述定子铁心和多组形制相同的所述永磁体；所述抱持装置，用于固定所述预制桩并使所述预制桩处于垂直状态；依靠所述永磁体与所述定子铁心间的调制作用，使得电枢绕组中的磁链发生交变，从而产生感应电势与电磁力，驱动所述驱动装置沿所述导轨上下移动。本发明打桩效率高，噪音低，使用时占地范围较小。
