The invention particularly relates to a crane cart running mechanism capable of continuously working for a long time. The crane cart running mechanism comprises four driving units and two or three sets of speed regulating devices, the four driving units are symmetrically arranged at four corners of the crane; the speed regulation device is configured to be in an in-use mode and a standby mode; each driving unit comprises two motors, two brake wheel couplings, two brakes, a speed reducer, two universal couplings, two driving wheel sets and one to eight driven wheel sets. In each driving unit, two motors input power from two input shafts of a speed reducer through brake wheel couplings directly connected with the motors, the power is converged in the speed reducer and then shunted, and the power output from the speed reducer drives driving wheels of a driving wheel set to rotate through universal couplings. The driving wheel set drags driven wheels of the driven wheel set to rotate through the trolley frame and the end beam, and then the whole crane is driven to move in parallel.
本发明具体涉及一种能长期连续工作的起重机大车运行机构,其包括四个驱动单元,以及两套或三套调速装置;四个驱动单元对称布置在起重机四个角的位置;调速装置被配置成为在用模式和备用模式;每个驱动单元包括两台电动机、两个制动轮联轴器、两个制动器、一台减速器、两根万向联轴器、两个主动车轮组和一至八个被动车轮组;每个驱动单元中,两台电动机通过与电动机直接相连的制动轮联轴器将功率从减速器的两输入轴输入,功率在减速器内合流后再分流,从减速器输出的功率通过万向联轴器再驱动主动车轮组的主动车轮旋转,主动车轮组通过台车架、端梁拖动被动车轮组的被动车轮旋转,进而带动整个起重机平行移动。
