The invention relates to the technical field of cranes, in particular to a lifting and sliding device for a crane, which comprises a moving trolley slidably arranged between double beams of the crane, the moving trolley comprises a frame and wheels, and the frame consists of a bottom plate, a front support frame and a rear support frame; driving devices are arranged at the positions, corresponding to the driving wheels, of the front supporting frame and the rear supporting frame, the driving devices drive the driving wheels to rotate, the lifting device is installed on the vehicle frame and comprises a lifting motor, a first winding drum and a second winding drum, and the lifting motor drives the first winding drum and the second winding drum to rotate. The problems that at the present stage, due to the design that a lifting mechanism with one winding drum needs enough braking torque and a single winding drum, installation and adjustment of a brake can become more complex, the braking difficulty is increased, meanwhile, the selection of connection modes between the winding drums and a speed reducer is limited, installation errors cannot be effectively compensated, the transmission precision is reduced, and the service life of the winding drum is prolonged are solved. And the overall performance of the hoisting mechanism is further influenced.

    本发明涉及起重机技术领域,具体涉及一种起重机用起升滑移装置,包括可滑动设置在起重机双梁之间的移动小车,移动小车包括车架和车轮,车架由底板、前支撑架和后支撑架组成,前支撑架和后支撑架对应着主动轮位置处设置有驱动装置,驱动装置驱动主动轮旋转,还包括有起升装置,起升装置安装在车架上,起升装置包括起升电机、第一卷筒和第二卷筒,起升电机驱动第一卷筒和第二卷筒转动,解决了现阶段一个卷筒的起升机构需要有足够的制动力矩单个卷筒的设计可能使得制动器的安装和调整变得更加复杂,增加了制动难度,同时,卷筒与减速器之间的连接型式选择有限,无法有效地补偿安装误差,导致传动精度降低,进而影响起升机构的整体性能的问题。
