Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figures 1 to 5, the utility model provides a kind of three-level door frame, including outer mast 1, middle door frame 2, inside door
The parts such as frame 3, goods shelf 12 and pipeline, middle door frame 2 be arranged at outer mast 1 open in shelves and both is are slidably connected, inner upright mounting 3
Be arranged at middle door frame 2 open in shelves and both is are slidably connected, goods shelf 12 is arranged at opening in shelves and and inner upright mounting for inner upright mounting 3
3 be to be slidably connected.This three-level door frame also includes preceding lift oil tank 4, rear lift oil tank 8, is located on inner upright mounting 3 and for driving goods
The first chain-drive mechanism and be located at the second Chain conveyer machine on middle door frame 2 and for driving inner upright mounting 3 to rise that crotch 12 rises
Structure.
Specifically, as depicted in figs. 1 and 2, preceding lift oil tank 4 is vertically arranged on inner upright mounting 3 and positioned at inner upright mounting 3
Open in shelves, the first chain-drive mechanism is opened in shelves positioned at inner upright mounting 3, the first chain-drive mechanism includes lift oil tank 4 before being arranged at
Piston rod on preceding cylinder sprocket wheel 13 and the preceding cylinder chain 5 that coordinates with preceding cylinder sprocket wheel 13 and be connected with goods shelf 12.Preceding cylinder chain 5
One end be connected with goods shelf 12, the other end is connected with inner upright mounting 3.Pipeline on three-level door frame includes being used for delivery hydraulic pressure oil
Preceding cylinder sebific duct 6, preceding cylinder chain 5 has the storage tank 7 for accommodating preceding cylinder sebific duct 6.When door frame works, preceding lift oil tank 4 is connect from multichannel
The pressure oil that valve is provided starts raising, rises cylinder chain 5 and preceding cylinder sebific duct 6 before driving by preceding cylinder sprocket wheel 13 and does ascending motion,
Preceding one end of cylinder chain 5 is connected on goods shelf 12, therefore goods shelf 12 does ascending motion with preceding cylinder raising relative to inner upright mounting 3,
Before the preceding movement travel of lift oil tank 4 does not terminate, goods shelf 12 is raised with preceding cylinder raising, and inner upright mounting 3 is in this period
Inactive state, therefore this section of stroke is referred to as full free travel.
As shown in Figure 1 to Figure 3, storage tank 7 to extend on preceding cylinder chain 5 along its length, and preceding cylinder sebific duct 6 is embedded in preceding cylinder
In storage tank 7 on chain 5.Preceding lift oil tank 4 is vertically arranged two in opening for inner upright mounting 3 in shelves, before left and right on lift oil tank 4
The position of cylinder sprocket wheel 13, preceding cylinder chain 5 and preceding cylinder sebific duct 6 before being respectively arranged, preceding cylinder sprocket wheel 13 and preceding cylinder sebific duct 6 not in door frame just
Middle position, before preceding cylinder chain 5 is arranged on cylinder sprocket wheel 13, carries chute on preceding cylinder chain 5, can meet and not slided by sebific duct
Before preceding cylinder sebific duct 6 is directly arranged in by wheel 11 on cylinder chain 5, and preceding cylinder sebific duct 6 and preceding cylinder chain 5 can be synchronized with the movement, so
The space to be preserved of door frame centre can just be gone out, it is ensured that driver has the good operation visual field, lift operating efficiency.
Middle door frame 2 can drive the raising and lowering of inner upright mounting 3 by the second chain-drive mechanism, as shown in Figure 4 and Figure 5, the
Two chain-drive mechanisms include the rear cylinder sprocket wheel 14 being located on middle door frame 2 and the rear cylinder chain 9 coordinated with rear cylinder sprocket wheel 14, rear cylinder chain
One end of bar 9 is connected with outer mast 1, and the other end is connected with inner upright mounting 3.Door in being vertically arranged with outer mast 1 for driving
Lift oil tank 8 after frame 2 rise two, after two the cylinder body of lift oil tank 8 be fixedly connected respectively with outer mast 1 it is parallel, moreover,
Lift oil tank 8 also is located at the rear of door frame afterwards.Afterwards the piston rod of lift oil tank 8 be from the stretching of the upper end of cylinder body, and with middle door frame 2
Connection.After current raising cylinder movement travel terminates, rear lift oil tank 8 is begun to ramp up, because the rear bottom of lift oil tank 8 is fixed on external door
On the sill of frame 1, top is connected on the entablature of middle door frame 2, therefore middle door frame 2 is done with the raising of rear lift oil tank 8
Elevator is moved；With inner upright mounting 3 as the rising principle of goods shelf 12, middle door frame 2 is also to be transmitted by sprocket wheel and chain with inner upright mounting 3
Motion.Lift oil tank 8 does ascending motion afterwards, and middle door frame 2 is directly synchronized with the movement by the rear jack-up of lift oil tank 8, and inner upright mounting 3
Then by sprocket wheel and chain-driving, because sprocket wheel now is time saving pulley, therefore the lifting velocity of inner upright mounting 3 is middle 2 raising speeds of door frame
Twice of degree.
As shown in Figure 4 and Figure 5, the pipeline on three-level door frame also includes being used for the rear cylinder sebific duct 10 of delivery hydraulic pressure oil, sebific duct
Pulley 11 and rear cylinder sprocket wheel 14 are arranged on the trailing flank of middle door frame 2, and rear cylinder sebific duct 10 bypasses sebific duct pulley 11.Cylinder sprocket wheel 14 afterwards
Post-modifier is used with sebific duct pulley 11, this structure allows on rear cylinder chain 9 and the sebific duct pulley 11 being arranged on rear cylinder sprocket wheel 14
Rear cylinder sebific duct 10, be arranged from the rear of the both sides of door frame, be not arranged, reserved on door frame from door frame centre position
The space of half part, it is ensured that driver has the good operation visual field, further lifts operating efficiency.
The utility model additionally provides a kind of fork truck, including above-mentioned three-level door frame.The concrete structure of this three-level door frame can
Referring to figs. 1 to Fig. 5, it will not be repeated here.Because fork truck of the present utility model includes the three-level door frame in above-described embodiment, so
It has all advantages of above-mentioned three-level door frame.
The utility model is exemplarily described above in association with accompanying drawing.Obviously, the utility model is implemented not
Limited by aforesaid way.As long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
