Abstract
The utility model discloses a mast of a forklift. The mast comprises an inner mast, an outer mast, a fork carrier and a fork, wherein the inner mast is embedded in the outer mast, the bottom ends of lifting oil cylinders are fixed on the lower part of the outer mast, and the upper ends of the lifting oil cylinders are fixed on the upper part of the inner mast; chain hanging plates, which stretch to the outer side of the outer mast, are respectively arranged on both sides of a top plate of the inner mast, and chain wheels are arranged on the chain hanging plates; the back of the outer mast is fixedly connected to chain fixing frames; one ends of chains are connected to the chain fixing frames while the other ends of the chains surrounds the chain wheels and are connected to the fork carrier. Two lifting oil cylinders are respectively arranged at the back positions of both sides of the inner mast. A big chain wheel and a small chain wheel are arranged on each chain hanging plate, and the small chain wheels are arranged on the back lower parts of the big chain wheels. When a forklift worker lifts a piece at work, the lifting oil cylinders are lifted to drive the inner mast to lift, the chain wheels on both sides of the inner mast are lifted along with the inner mast, the fork carrier is simultaneously driven to lift through the chains, and cargos on the fork are lifted to a required height.
Description
Technical field
The utility model belongs to the fork truck vehicular field, is specifically related to a kind of forklift door frame.
Background technology
The forklift door frame system generally is made up of inner upright mounting, outer mast, goods shelf, pallet fork, sprocket wheel, chain, lift oil tank and dump ram etc.The outer mast lower end is hinged on the vehicle frame, and middle part and dump ram are hinged, and inner upright mounting has roller, is embedded in the outer mast.Goods shelf has roller, is embedded in the inner upright mounting, can up-and-down movement.Two lift oil tanks are arranged in the door frame both sides, and the bottom of lift oil tank is fixed on the outer mast bottom.Sprocket wheel is equipped with at the top of piston rod, and chain one end that hoists is fixed on the outer mast, and the other end is walked around sprocket wheel and linked to each other with goods shelf.When the piston rod part band sprocket wheel and is hoisted, no matter be goods shelf, pallet fork improvement stage, or the inner upright mounting improvement stage, they all hoist with the stroke of 2 times of lift oil tanks.Pallet fork hoists and the inner upright mounting maximum height that pallet fork can hoist when motionless is called free hoisting depth.General free hoisting depth is 300 millimeter.When goods shelf rise be raised to the inner upright mounting top after, inner upright mounting just and the door frame that hoists simultaneously of goods shelf is called the full door frame that freely promotes.Fork truck sprocket wheel more than 10 tons directly is fixed on the inner upright mounting top mostly, and lift oil tank pushes up the act door frame at the very start, so can not freely promote.General forklift door frame, sprocket wheel, chain all are positioned at the inner position of door frame, influence the range of visibility of chaufeur easily.Goods shelf is near apart from center-point, causes goods lateral deviation and weightlessness easily, comes inevitable potential safety hazard for people, goods, car, causes very big loss.
Summary of the invention
The purpose of this utility model provides a kind of broad visual field that has, and visible angle is big, and the high forklift door frame of reliability.
Forklift door frame of the present utility model comprises inner upright mounting, outer mast, goods shelf, pallet fork; Described inner upright mounting interlocking is in outer mast, and the lift oil tank bottom is fixed on the outer mast bottom, and the lift oil tank upper end is fixed on inner upright mounting top; The top board both sides of described inner upright mounting have a chain link plate that extends to the outer mast outside respectively, and sprocket wheel is installed on the chain link plate; The rear portion of outer mast is fixedly connected with the chain fixed mount; Chain one end connects the chain fixed mount, and the other end is walked around sprocket wheel, connects goods shelf.
As optimization, described lift oil tank has two, is separately positioned on the rear position of inner upright mounting both sides.A hinge wheel and a minor sprocket are installed on described each chain link plate, and minor sprocket is positioned at wheel position, the back lower place, Dalian.
During work, lift oil tank rose when the Forklift Worker played part, drove inner upright mounting and rose, and the sprocket wheel of inner upright mounting both sides also rises with inner upright mounting, and goods shelf rises simultaneously by the drive of chain, and the freight lifting that is contained on the pallet fork is arrived the height that needs.
The utility model forklift door frame, sprocket wheel be installed in inner upright mounting extend to the outside the chain link plate on, chain moves outward the pulling force of goods shelf like this, increased reliability in the lifting to goods, keep in repair also faster easyly, simultaneously also expanded the range of visibility of the person of sailing, strengthened visible angle.

The specific embodiment
Forklift door frame as Fig. 1, Fig. 2, shown in Figure 3, comprises inner upright mounting 1, outer mast 2, goods shelf 3, pallet fork 4; Inner upright mounting 1 interlocking is in outer mast 2, and lift oil tank 5 has two, is separately positioned on the rear position of inner upright mounting 1 both sides.Lift oil tank 5 bottoms are fixed on outer mast 2 bottoms, and lift oil tank 5 upper ends are fixed on inner upright mounting 1 top;
The rear portion of outer mast 2 is fixedly connected with chain fixed mount 10; Chain 11 1 ends connect chain fixed mount 10, and the other end is walked around hinge wheel 8, minor sprocket 9, connect goods shelf 3.
During work, lift oil tank 5 rose when the Forklift Worker played part, drove inner upright mounting 1 and rose, and the hinge wheel 8 of inner upright mounting 1 both sides, minor sprocket 9 also rise with inner upright mounting 1, goods shelf 3 rises simultaneously by the drive of chain 11, and the freight lifting that is contained on the pallet fork 3 is arrived the height that needs.
