The invention relates to the technical field of forklift door frames, and particularly discloses a door frame lifting control system which comprises a first sensing assembly and a second sensing assembly, a door frame comprises an outer door frame body, a middle door frame body and an inner door frame body, the middle door frame body is connected with the outer door frame body in a lifting mode, and the inner door frame body is connected with the middle door frame body in a lifting mode. The lifting height of the inner gantry is twice that of the middle gantry, a liftable fork assembly is arranged on the inner gantry, the lifting height of the middle gantry is monitored through a first sensing assembly, the lifting height of the fork assembly is monitored through a second sensing assembly, and the lifting height of the inner gantry can be obtained through the first sensing assembly. The lifting height of the pallet fork assembly can be obtained through the second sensing assembly, the final lifting height of the pallet fork assembly can be obtained by adding the first sensing assembly and the second sensing assembly, accurate monitoring is achieved, pulley sensors are adopted in the first sensing assembly and the second sensing assembly, a stay wire encoder does not need to be arranged, the cost is far lower than that of the stay wire encoder, and damage is not likely to happen.
本发明涉及叉车门架的技术领域,并具体公开一种门架起升控制系统,包括第一传感组件以及第二传感组件,门架包括外门架、中门架以及内门架,中门架可升降的与外门架相接,内门架可升降的与中门架相接,且内门架的提升高度为中门架提升高度的两倍,并在内门架上设有可升降的货叉组件,通过第一传感组件监测中门架的提升高度,通过第二传感组件监测货叉组件的提升高度,通过第一传感组件可以得出内门架的提升高度,通过第二传感组件可以得出货叉组件提升高度,两者相加便能得到货叉组件的最终提升高度,实现精准监控,且第一传感组件与第二传感组件均采用滑轮传感器,其不需要设置拉线编码器,成本远低于拉线编码器,且不易损坏。
