The invention provides an open tooth external cart mechanism of a portal crane. The mechanism comprises a large balance beam, the lower ends of the two sides of the large balance beam are connected with two symmetrical small balance beams through small shafts, and the lower end of one side of each small balance beam is connected with a driving trolley set through a first hinge shaft device. The lower end of the other side of each small balance beam is connected with a driven trolley set through a second hinge shaft device. Each driving trolley set comprises a first driving gear device, a second driving gear device and a large gear device which are rotationally connected to the driving trolley set. According to the mechanism, the defects in the prior art are overcome, the design is reasonable, the structure is compact, the stability is improved by using the plurality of small balance beams, the moving stability is improved by adopting pinion devices, the cart mechanism is moved and mounted to the outer side by using transmission teeth mounted in the driving trolleys of the cart mechanism, maintenance personnel can conveniently observe in daily life and timely know the operation condition of the transmission teeth, problems can be conveniently and timely found and solved, and a first-time response program is started.
本发明提供了门式起重机开式齿外置式大车机构,包括大平衡梁,大平衡梁的两侧下端均通过小轴连接有两个对称的小平衡梁,小平衡梁的一侧下端通过第一铰轴装置连接有驱动台车组,小平衡梁的另一侧下端通过第二铰轴装置连接有从动台车组;驱动台车组包括转动连接在驱动台车组上的第一驱动齿轮装置、第二驱动齿轮装置和大齿轮装置。本发明克服了现有技术的不足,设计合理,结构紧凑,本发明用多个小平衡梁提高了稳定性,同时采用了小齿轮装置提高了移动的稳定性,而且安装于大车机构主动台车内部的传动齿,使其搬移安装至外侧,让维修人员日常便于观察可及时了解传动齿的运行状况,便于及时发现问题及时解决,开启第一时间响应程序。
