The portal crane comprises a bottom plate, a first sliding plate, a second sliding plate and a driving mechanism, wherein the first sliding plate and the second sliding plate are arranged on the bottom plate in a sliding mode, and the driving mechanism is used for driving the first sliding plate and the second sliding plate to slide on the bottom plate. The driving mechanism comprises a power assembly, a traction rope, a first rolling piece and a second rolling piece, the first rolling piece and the second rolling piece are rotationally arranged at the two ends of the bottom plate respectively, the traction rope is arranged on the two rolling pieces in a sleeving mode, and the first sliding plate and the second sliding plate are fixed to the traction rope. The power assembly is used for driving the traction rope to move so as to drive the first sliding plate and the second sliding plate to get close to each other or get away from each other. According to the portal crane, a motor, a synchronous belt, a synchronous belt clamp, a synchronous belt driven adjusting wheel assembly and the like in a traditional portal crane structure are omitted, the portal crane structure directly provides force to be applied to the traction rope through the power assembly, the portal crane structure is greatly simplified, and meanwhile the size of the portal crane bottom plate can be reduced.

    本发明公开了一种门机,包括底板、滑动设置在所述底板上的第一滑板和第二滑板、用于驱动所述第一滑板和第二滑板在所述底板上滑动的驱动机构;所述驱动机构包括动力组件、牵引绳、第一滚动件和第二滚动件,所述第一滚动件和第二滚动件分别转动设置在所述底板的两端部,所述牵引绳套设在两个滚动件上,所述第一滑板和第二滑板与所述牵引绳固定,所述动力组件用于驱动所述牵引绳移动进而带动所述第一滑板和第二滑板之间相互靠近或远离。本发明的门机,取消了传统门机结构中的马达、同步带、同步带夹、同步带从动调节轮组件等,本申请的门机结构将动力组件直接提供力施加在牵引绳上,极大的简化了门机结构,同时门机底板的尺寸可以缩小。
