Abstract
The utility model relates to a ground transportation equipment especially relates to a pile portal system of high car. A pile portal system of high car, the portal system is including vertical portal main part that sets up at frame front end middle part to it slides to reach sets up the fork frame on the terminal surface before the frame, and is used for driving fork frame longitudinal movement's lift cylinder, and passes through the hydraulic pressure oil circuit oil pump continuous with lift cylinder, and supplementary fork frame longitudinal movement's sprocket structure, during the use, lift cylinder driving sprocket seat longitudinal movement stabilizes the lifting or puts down the fork frame through receiving and releasing of chain, has promoted the stability of fork frame lifting.
Description
Technical field
The utility model relates to a kind of ground means of transportation, particularly relates to a kind of portal frame system of forklift.
Background technology
Forklift refers to the various wheeled carrying vehicle loading and unloading, pile high, stacking and short range hauling operation to member pallet cargo; Its structure generally comprises vehicle frame, and is arranged on driving assembly, handle assembly and the portal frame system on vehicle frame, and control to drive assembly to run by handle assembly during use, namely vehicle is advanced; High, stacking and handling goods is piled by the goods shelf lifting on portal frame system.But the portal-framed structure of existing forklift is complicated and stability is not enough, thus the environment for use of constraint forklift.
Summary of the invention
In order to solve the problem, the purpose of this utility model is the portal frame system providing a kind of forklift, and this portal frame system is simple and reasonable for structure, and improves the stability of goods shelf lifting.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of portal frame system of forklift, described portal frame system comprises the door frame main body being longitudinally arranged on vehicle frame front center, and the goods shelf be slidably arranged on vehicle frame front end face, and the hoist cylinder for driving goods shelf to vertically move, and by the oil pump that hydraulic circuit is connected with hoist cylinder, and the chain sprocket structure that auxiliary goods shelf vertically moves; Described door frame main body is axially provided with opening door frame groove forward along it, hoist cylinder is fixed in door frame groove, the cylinder body upper end of hoist cylinder is fixed on the axially middle part of door frame groove, and the cylinder body lower end of hoist cylinder props up door frame main body, and the output shaft of hoist cylinder longitudinally upward; Described chain sprocket structure comprises the chain pulley seat be fixed on hoist cylinder output shaft, and is positioned at the sprocket wheel on chain pulley seat by bearing, and is erected at the chain on sprocket wheel race, and the both ends of chain are separately fixed on door frame main body and goods shelf.
As preferably, described goods shelf is provided with two pallet fork legs, two pallet fork legs are symmetricly set on the both sides, front end of vehicle frame.
The utility model adopts technique scheme, the portal frame system structure of this forklift is simple, door frame main body in portal frame system is provided with door frame groove, hoist cylinder is fixed in door frame groove, chain pulley seat is fixed on the output shaft of hoist cylinder, is erected at chain two ends connection door frame body and the goods shelf respectively of chain pulley seat; During use, hoist cylinder driving chain wheel seat vertically moves, and stablizes lifting or put down goods shelf by the folding and unfolding of chain.
