The invention discloses a double-beam bridge crane which comprises a main beam, a cart traveling mechanism and a crane carriage, the crane carriage is connected with a horizontally-arranged mounting part through a steel wire rope, a lifting appliance is mounted on the mounting part and comprises two sliding plates arranged at intervals, one side of each sliding plate is connected with the mounting part, and the other side of each sliding plate is connected with the cart traveling mechanism. The other side of the sliding plate is slidably connected with a vertically-arranged guide column, the sliding plate is further provided with a lifting driving mechanism used for driving the guide column to ascend and descend in the vertical direction of the sliding plate, the lower portion of the guide column is slidably connected with an insertion column parallel to the main beam, the guide column is provided with an installation hole, and the insertion column penetrates through the installation hole and is slidably connected with the installation hole. The outer side wall of the guide column is fixedly connected with a translation driving mechanism used for driving the insertion column. The two inserting columns are arranged in the lifting appliance, so that the stability of the tubular part in the lifting process is improved, and meanwhile, the two inserting columns can move in the horizontal direction under the action of the translation driving device, so that the size range of the tubular part capable of being lifted by the lifting appliance is conveniently expanded.
本发明公开了一种双梁桥式起重机,包括主梁、大车行走机构、起重小车,起重小车通过钢丝绳连接有水平设置的安装件,安装件上安装有吊具,吊具包括两个间隔设置的滑板,滑板的一侧与安装件相连,滑板的另一侧滑动连接有竖直设置的导柱,滑板上还安装有用于驱动导柱沿着滑板的竖直方向升降的升降驱动机构,导柱的下部滑动连接有与主梁相平行的插柱,导柱上开设有安装孔,插柱穿过安装孔并与安装孔滑动连接,导柱的外侧壁上固定连接有用于驱动插柱的平移驱动机构。通过在吊具中设置两个插柱提高了管状件吊装过程中稳定性,同时,两个插柱可以在平移驱动装置的作用下进行水平方向的移动,从而便于扩大该吊具所能起吊的管状件的尺寸范围。
