The invention belongs to the technical field of shield tunneling machines, and particularly relates to a jacking device of a shield tunneling machine and a using method thereof.The jacking device of the shield tunneling machine comprises a bottom plate, a first square top pier is arranged on the bottom plate, a jack oil cylinder is arranged on the first square top pier, a shield body is arranged above the bottom plate, and a first triangular top pier is arranged on the side wall of the shield body; a jack oil cylinder is arranged on the bottom plate, an oil way is connected to the side wall of the jack oil cylinder in a penetrating mode, a high-pressure ball valve is arranged on the oil way, a second square top pier is arranged on the bottom plate and arranged on one side of the bottom plate, and a second triangular top pier is arranged on the side wall of the shield body. The high-pressure ball valve is mounted on the oil way of the jack oil cylinder, so that the jack oil cylinder can be freely combined, linked and independently controlled. By means of the design, accuracy and flexibility in the jacking process are greatly improved, the working state of each oil cylinder can be flexibly adjusted according to actual working conditions and needs, and the risk of shield body rollover caused by stroke deviation of the jack is effectively avoided.
本发明属于盾构机技术领域,具体是指一种盾构机的顶升装置及其使用方法,包括底板,所述底板上设有方型顶墩一,所述方型顶墩一上设有千斤顶油缸,所述底板的上方设有盾体,所述盾体的侧壁上设有三角顶墩一,所述千斤顶油缸的侧壁上贯通连接油路,所述油路上设有高压球阀,所述底板上设有方型顶墩二,所述方型顶墩二设于底板的一侧,所述盾体的侧壁上设有三角顶墩二;本申请通过在千斤顶油缸的油路上安装高压球阀,实现了千斤顶油缸的任意组合联动和单独控制。这种设计极大地提高了顶升过程中的精确性和灵活性,可以根据实际工况和需要,灵活调整各个油缸的工作状态,有效避免了因千斤顶行程偏差导致的盾体侧翻风险。
