Commissure starts to damage, and influences the quality of product；In addition, the raising chain stays of welding also need to polish after welding, technological process
It is longer, influence production efficiency.Therefore, it is necessary to existing forklift lifting chain stays are improved and optimized.
The content of the invention
To solve the deficiencies in the prior art, the short integral type lifting chain of a kind of not easy damaged of present invention offer, production procedure
Bar seat.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of forklift lifting chain stays, include the sprocket wheel seat board of rectangle, and sprocket wheel seat board lower end side is provided with normal thereto
Cylinder head seat board, sprocket wheel seat board outside are provided with sprocket wheel spindle nose, and sprocket wheel seat board, cylinder head seat board and sprocket wheel spindle nose use cast steel integrally casting
Form；The cylinder head seat board bottom surface is provided with a cylinder head counterbore, and cylinder head seat board upper side, which is provided with, always passes to cylinder head counterbore center
Mounting hole；The cylinder head seat board end is set to semicircle shape, and cylinder head counterbore center and the semicircle center of circle overlap.
The sprocket wheel spindle nose center is provided with a screwed hole.
The sprocket wheel spindle nose is provided with the spindle nose base portion greater diameter than sprocket wheel spindle nose, sprocket wheel spindle nose with sprocket wheel seat board junction
End outer ring be provided with an outer ring annular groove.
The side of the sprocket wheel seat board and cylinder head seat board is connected with positioning reinforcing plate, positioning reinforcing plate and sprocket wheel seat board and cylinder
Headstock plate is integrally cast, and its top surface is concordant with chain pulley seat plate top surface.
The positioning reinforcing plate and sprocket wheel seat board and the junction rounding off of cylinder head seat board.
The beneficial effects of the invention are as follows：By the way that original chain pulley seat, left and right cylinder head seat and sprocket wheel spindle nose are all integrated into
Cast steel integral piece, and the first from left right side is symmetrically fixed on the downside of entablature both ends, reduces and eliminate the material that plate cutting is brought
Loss, production cost is reduced, avoids temperature distortion that large-area welding brings and the shortcomings of workpiece easily damages from commissure,
Greatly improve the quality of product；The process for eliminating welding and postwelding polishing, reduces technological process, improves production effect
Rate.
Brief description of the drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view structural representation of the present invention；
Fig. 2 is the main structure diagram of the present invention；
Fig. 3 is the overlooking the structure diagram of the present invention.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of forklift lifting chain stays, it is characterised in that：Sprocket wheel seat board 1 including rectangle, chain pulley seat
The lower end side of plate 1 is provided with cylinder head seat board 2 normal thereto, and the outside of sprocket wheel seat board 1 is provided with sprocket wheel spindle nose 3, sprocket wheel seat board 1, cylinder head
Seat board 2 and sprocket wheel spindle nose 3 are integrally cast using cast steel.By by original chain pulley seat, left and right cylinder head seat and sprocket wheel spindle nose
Cast steel integral piece is all integrated into, and the first from left right side is symmetrically fixed on the downside of entablature both ends, reduces and eliminate plate cutting
The spillage of material brought, production cost is reduced, avoid temperature distortion and workpiece that large-area welding brings easily from commissure
The shortcomings of damage, greatly improve the quality of product；The process for eliminating welding and postwelding polishing, reduces technological process, carries
High production efficiency.In addition, the bottom surface of cylinder head seat board 2 is also provided with a cylinder head counterbore 4, the upper side of cylinder head seat board 2 is provided with always
Pass to the mounting hole 5 at the center of cylinder head counterbore 4.Coordinated by bolt through mounting hole 5 and oil cylinder take-off lever end, can be defeated by oil cylinder
Rod end is fixed in cylinder head counterbore 4, not only makes attachment structure compacter, also the power of oil cylinder is preferably delivered to
On cylinder head seat board 2, conversion efficiency is higher.
As the further improvement of above-mentioned technical proposal, the end of cylinder head seat board 2 is set to semicircle shape, in cylinder head counterbore 4
The heart and the semicircle center of circle overlap.Such setting, make the outward appearance of one integral piece integral type raising chain stays more attractive, integrally tied after assembling
It is more reasonable.
As the further improvement of above-mentioned technical proposal, the center of sprocket wheel spindle nose 3 is provided with a screwed hole 6.By using
Sprocket wheel easily can be arranged on sprocket wheel spindle nose 3 by bolt, and dismantled maintenance and be convenient to.
As the further improvement of above-mentioned technical proposal, the sprocket wheel spindle nose 3 is provided with a diameter with the junction of sprocket wheel seat board 1
More than the spindle nose base portion 7 of sprocket wheel spindle nose 3, the end outer ring of sprocket wheel spindle nose 3 is provided with an outer ring annular groove 8.Spindle nose base portion 7 can be effective
Increase sprocket wheel spindle nose 3 structural strength, bigger pressure can be born, at the same also avoid sprocket wheel directly with sprocket wheel seat board
1 contact, reduces friction, improves the service life of sprocket wheel.
As the further improvement of above-mentioned technical proposal, the side of the sprocket wheel seat board 1 and cylinder head seat board 2 is connected with positioning
Reinforcing plate 9, positioning reinforcing plate 9 are integrally cast with sprocket wheel seat board 1 and cylinder head seat board 2, and its top surface is put down with the top surface of sprocket wheel seat board 1
Together.By positioning reinforcing plate 9 and being connected on entablature into L shapes of sprocket wheel seat board 1, make the positioning of one integral piece raising chain stays more
Simply, the concordant top surface concora crush of positioning reinforcing plate 9 and sprocket wheel seat board 1 need to be only connected on entablature, without adjusting
It is whole, it will not tilt, so as to greatly improve precision, reduce the error in assembling；Meanwhile by positioning reinforcing plate 9 in side
Face connection chain pulley seat plate 1 and cylinder head seat board 2, greatly enhance overall construction intensity, make the structure of one integral piece raising chain stays more
Add stabilization.
As the further improvement of above-mentioned technical proposal, positioning reinforcing plate 9 and the sprocket wheel seat board 1 and cylinder head seat board 2
Junction rounding off.Junction rounding off, one integral piece raising chain stays can be avoided to be damaged since the junction at right angle, together
When increase the thickness of junction, make that its attachment structure is more solid, and intensity is higher.
Described above, the simply better embodiment of the present invention, but the present invention is not limited to above-described embodiment, if its with
Any same or similar means reach the technique effect of the present invention, should all be included within protection scope of the present invention.
