The invention relates to a forklift portal frame chain seat and a forklift, which are used for driving a forklift portal frame to ascend and descend on the forklift and comprise a base connected with an oil cylinder, a chain assembly, a guide assembly and a correcting assembly. The oil cylinder oil pipe is arranged in the first limiting channel on the chain assembly, the oil cylinder oil pipe is preliminarily limited through the first limiting channel on the premise that the structural strength of the chain assembly is not affected, and the oil cylinder oil pipe can be further limited by matching the second limiting channel with the first limiting channel; the chain assembly is arranged on the chain wheel, the limiting effect on the oil cylinder oil pipe is improved, the oil cylinder oil pipe cannot be twisted, meanwhile, the chain is arranged on the chain wheel, the chain wheel can be used for limiting the chain assembly, and the limiting effect on the oil cylinder oil pipe can be improved; and the correcting assembly is driven to stir the oil cylinder oil pipe which does not enter the first limiting channel and the second limiting channel, so that the oil cylinder oil pipe is further prevented from being twisted in the moving process.
本申请涉及一种叉车门架链条座及叉车,用于带动叉车门架在叉车上升降,包括:与油缸相连的基座,链条组件,导向组件,拨正组件。将油缸油管设置在链条组件上的第一限位通道中,在不影响链条组件自身结构强度的前提下,通过第一限位通道对油缸油管进行初步限位,利用第二限位通道配合第一限位通道能够对油缸油管进行进一步限位,提高对油缸油管的限位效果,使其不会发生扭曲,同时将链条设置在链轮上,从而能够利用链轮对链条组件进行限位,进而也能够提高对油缸油管的限位效果,另外,利用链轮自身的转动,带动拨正组件能够拨动未进入第一限位通道和第二限位通道的油缸油管,进一步减小了油缸油管不会在移动过程中发生扭曲。
