The invention relates to a chain guiding piece, a chain type manual device and winch type power equipment, the chain guiding piece comprises a fixing structure used for being fixed to a rack and further comprises two guiding holes allowing the two side edges of an overhanging type annular chain to penetrate through respectively, the chain guiding piece is provided with lateral openings communicated with the guiding holes, and the guiding holes are communicated with the fixing structure. The center distance between the two guide holes is smaller than the diameter of a chain wheel assembled with the annular chain in a meshed mode. The chain type manual operation device effectively solves the problem that in the prior art, a chain in a chain type manual operation device is prone to tooth skipping and slipping.
本发明涉及一种链条导向件及链式手动装置及卷扬式动力设备,其中,链条导向件包括用于固定在机架上的固定结构,还包括两个分别供悬垂式环形链条的两个侧边穿过的导向孔,链条导向件上设置有与各导向孔连通的侧向开口,以供环形链条的侧边装入导向孔内,两个导向孔之间的中心距小于与环形链条啮合装配的链轮的直径。本发明有效解决了现有技术的链式手动操作装置中链条容易出现跳齿、打滑的问题。
