Abstract
The utility model discloses including cylinder barrel and the piston rod with being inserted in inner cavity of cylinder, piston rod is head end in the side outside cylinder barrel, and opposite side is end, in the interior intracavitary of cylinder barrel, the end of piston rod is provided with piston one and piston two, and piston one is bonded with piston two but do not interfixed.Sealed between piston two and cylinder barrel by sealing ring, its side center adjacent with piston one is provided with short push rod, and short push rod is in contact with piston one side.The utility model is by separating piston two with piston rod to make piston two be in center all the time, during so as to overcome piston rod to be in eccentric state compensating cylinder occur oil leak, operation when balance failure the defects of, normal production operation process is ensured, its is simple in construction, ingenious in design.
Description
Technical field
Field of steel production is the utility model is related to, specifically a kind of milling train double-piston balance hydraulic cylinder.
Background technology
When being worked due to milling train, existing gap can cause impact between relevant part, thus balance dress is equipped with milling train
Put, balance hydraulic cylinder（Hereinafter referred to as compensating cylinder）It is the more conventional bascule of one of which.But milling train is stinging steel, is throwing steel mistake
The horizontal level of Cheng Zhong, working roll and its bearing block before and after milling train stings steel is moved, and drives the piston rod of compensating cylinder to do water
Flat motion, so that piston rod is in eccentric state.Piston rod stretching is longer, and its eccentric state is more obvious.When piston rod is in
When eccentric state works, also there is bias in the piston being fixedly connected with piston rod, causes compensating cylinder oil leak, and then balance occurs and lose
The situation of effect, influence production operation process.
Based on this, this case application is proposed.
The content of the invention
The utility model provides a kind of milling train double-piston balance hydraulic cylinder, by setting the double-piston of separation, to overcome
When compensating cylinder occurs when it eccentric state occurs under inclined loading condition oil leak and operation the defects of balance failure.
To achieve the above object, the technical solution adopted by the present invention is：A kind of milling train double-piston balance hydraulic cylinder, including cylinder
Cylinder and the piston cylinder bar being connected with cylinder barrel movable sealing, it is head end that piston rod, which is located in the side outside cylinder barrel, and opposite side is end
End.In the interior intracavitary of cylinder barrel, the end of the piston rod is provided with piston one, piston two it is adjacent with piston one and positioned at piston rod with
Between the end of cylinder barrel.Sealed between piston two and cylinder barrel by sealing ring, its side center adjacent with piston one is provided with short
Push rod, short push rod are in contact with piston one side.
Preferably, the ram surface is sphere.
Preferably, the head end of the piston one, end and cylinder barrel junction are arc chord angle.
The beneficial effects of the utility model：First, when milling train works, piston one is in piston rod under horizontal force action
Eccentric state, but because piston one separates with piston two, therefore when piston two is not influenceed by horizontal force, can protect all the time
Hold it and be in the center of cylinder barrel, so as to prevent because the oil leak caused by piston rod bias the occurrence of, reduce horizontal
Power influences on oil cylinder, extends the service life of seal and compensating cylinder, and reduces the maintenance cost and maintenance time of equipment, protects
Demonstrate,prove normal production process, improve production efficiency.
2nd, the both ends of piston one use circular arc degree structure design in the utility model, reduce as much as possible piston one with
The effective area of cylinder barrel contact, so that it is guaranteed that after piston rod is by side force, the influence after the bias of piston one to cylinder barrel is minimum,
A problem that avoiding a pair of cylinder tubes of piston from causing to scratch, killing.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model specific embodiment.
Fig. 2 is the working state figure of the utility model specific embodiment.
Wherein：1-cylinder barrel, 2-piston rod, 3-guide sleeve, 4-dust ring, 5-piston one, 6-piston two, 7-short
Push rod, 8-oil inlet, 9-working chamber.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in figure 1, a kind of milling train double-piston balance hydraulic cylinder, including cylinder barrel 1 and piston rod 2.Open the side of cylinder barrel 1
Mouthful, open side is provided with guide sleeve 3；Its opposite side is closed, and its side closed is provided with oil inlet 8, the hollow space between both sides
For inner chamber.Piston rod 2 is inserted in inner chamber by guide sleeve 3, and it is head end that it, which is located at 1 outer side of cylinder barrel, and it is located at the interior of cylinder barrel 1
Side in chamber is end.Dust ring 4 is provided between the head end and guide sleeve 3 of piston rod 2.Piston one is provided with the inner chamber of cylinder barrel 1
5th, piston 26, piston 1 are fixed on the end of piston rod 2, and head end, end and the junction of cylinder barrel 1 of piston 1 are arc chord angle.
Piston 26 is disposed adjacent with piston 1, and it is tightly connected between cylinder barrel 1 by sealing ring.Piston 26 is adjacent with piston 1
Side center be provided with and short push rod 7 and be close to piston 1.
Compensating cylinder is generally vertically arranged on milling train, and its head end is upward, end sets down.After being refueled into oil inlet 8,
Hydraulic oil is full of in working chamber 9, the working chamber 9 gradually increased pushes piston 26 and moved upwards, and piston 26 will by short push rod 7
Thrust, which is transferred to piston 1 and piston rod 2, makes one with motion upwards.When piston rod 2 declines under external force, piston 1
By short push rod 7 pressure is transmitted to push piston 26 and make its decline, hydraulic oil is discharged from oil inlet 8, while working chamber 9 by
It is decrescence small.When piston rod 2 is by the effect of horizontal force and when being in eccentric state, the piston 1 being fixedly connected with piston rod 2
In eccentric state, but because piston 26 and piston 1 are non-linkages, therefore piston 26 is not by the eccentric state of piston rod 2
Influence, all the time in center, so compensating cylinder is not in the situation of oil leak and balance failure.
Based on above-mentioned, the utility model is provided with piston 1 and piston 26, and piston 1 is used as the fulcrum of the activity of piston rod 2,
It can be eccentric and eccentric with piston rod 2；Piston 26 is used as the separator for separating the inner chamber of cylinder barrel 1, and it is not inclined by piston rod 2
The influence of heart shaped state.The utility model is simple in construction, ingenious in design, can be effectively improved existing compensating cylinder because piston rod 2 is eccentric
Caused oil leak, Balancing relization the occurrence of, so that it is guaranteed that under the eccentric state of piston rod 2 compensating cylinder normal operation, protect
Demonstrate,prove milling train normal work, improve production efficiency.
As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature
Scheme is applied to realize.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only
's.It is all in the scope of the utility model or in the change being equal in the scope of the utility model by the utility model bag
Contain.
