The invention provides a lifting system of a pile driver. The lifting system comprises an automatic reset bidirectional alignment jacking mechanism, a lower support, an oil cylinder lower cross, a lifting oil cylinder, an oil cylinder upper cross, an upper support, a ball cup, a stand column and a stand column fulcrum shaft, wherein the stand column fulcrum shaft and the automatic reset bidirectional alignment jacking mechanism are arranged at the two ends of a pile driver machine platform respectively; the stand column is supported on the pile driver machine platform through the stand column fulcrum shaft; a lifting oil cylinder rod is connected with the upper support through the oil cylinder upper cross; a lifting oil cylinder barrel is connected with the lower support through the oil cylinder lower cross; the ball cup is fixedly arranged on the side face of the stand column; the automatic reset bidirectional alignment jacking mechanism comprises a jacking oil cylinder, a bidirectional hinged support and at least two reset springs; the bidirectional hinged support is fixedly arranged on the pile driver machine platform; the jacking oil cylinder is arranged on the bidirectional hinged support; one end of each reset spring is arranged on the jacking oil cylinder, and the other end of each reset spring is arranged on the pile driver machine platform. The lifting system has the beneficial effects of being simple in structure and high in reliability.
Description
technical field [0001] The invention belongs to the technical field of pile driving machinery, and in particular relates to a lifting system of a pile driver. Background technique [0002] Use the power of the oil cylinder to convert the column of the pile machinery from the horizontal state (transportation state) to the vertical state (working state), and vice versa, the column can also be converted from the vertical state to the horizontal state. This operation is called column lifting. The column lifting of pile machinery has a great influence on the construction, especially the crawler type pile frame. Due to the need for overall transportation, its external dimensions need to be limited, and the mechanical space requirements are very compact. Therefore, the column lifting mechanism is required to have a simple structure, High reliability, small footprint and so on. At present, there are mainly two typical column lifting methods at home and abroad. [0003] A column li...
