The invention belongs to the technical field of cranes, and provides a large pin tooth follow-up transmission mechanism of an inclined strut type mast crane, which comprises a chassis, a pin tooth rotary disc is arranged at the top of the chassis, and a rotary structure is arranged at the top of the pin tooth rotary disc. The transmission gear can slide up and down on the surface of the output shaft of the speed reducer, and the transmission gear moves along with the deformation of the pin tooth rotary disc in a matched mode under the action of the follow-up spring, so that when the pin tooth rotary disc rotates to generate downward interference or upwarp, the follow-up spring enables the transmission gear to move adaptively, and the normal working state is kept; the problems of abrasion and interference of the transmission gear and the pin teeth are effectively solved, the service life of the whole transmission device is prolonged, the device is simple and practical in structure and convenient to disassemble and maintain, the operation and maintenance cost of enterprises is greatly reduced, and the equipment operation and maintenance efficiency is improved.
本发明属于起重机技术领域,本发明提供了一种斜撑式桅杆起重机大型销齿随动传动机构,包括底盘,底盘的顶部设置有销齿回转盘,销齿回转盘的顶部设置有回转结构,本发明通过改进斜撑式桅杆起重机的减速装置,通过增加随动装置,使传动齿轮可上下滑动于减速机输出轴表面,并结合随动弹簧的作用,使传动齿轮随销齿回转盘的形变配合移动,从而使得销齿回转盘转动出现下扰或者上翘时,随动弹簧会使传动齿轮适应性移动从而保持正常工作状态,有效解决了传动齿轮与销齿的磨损和干涉问题,从而整个传动装置的使用寿命,而且本装置结构简洁实用且拆卸维护方便,从而大大降低了企业运维成本,并提高了设备运维效率。
