The invention discloses a novel single-cylinder bolt type telescopic system, which is characterized by comprising an oil way integrated block and a telescopic balance valve bank. The oil way integrated block is arranged at the position of a cylinder head of the hydraulic cylinder, and the telescopic balance valve bank is arranged on the side portion of the oil way integrated block. According to the novel single-cylinder bolt type telescopic control method, a new arrangement mode and a new control mode are adopted, so that the problems that the crane oil way integrated block is limited by the telescopic balance valve and cannot be shrunk, and a system backpressure high-telescopic balance valve cannot be completely closed can be thoroughly solved; in addition, the novel design method is simple in structure, and all the problems can be solved only by arranging the telescopic balance valve on the lower side and additionally arranging one electromagnetic reversing valve.

    本发明公开了一种新型单缸插销式伸缩系统,其特征在于,包括油路集成块、伸缩平衡阀组;所述油路集成块设于液压缸的缸头处,所述伸缩平衡阀组设于油路集成块的侧部;一种新型单缸插销式伸缩控制方法;采用新的布置方式和控制方式,可以彻底解决起重机油路集成块受伸缩平衡阀所限无法缩小的问题和系统背压高伸缩平衡阀无法完全关闭的问题;此外新的设计方法,结构简单,只需要将伸缩平衡阀布置在下侧和增加一个电磁换向阀就可以解决上述所有问题。
