Abstract
A joint for conveniently supplying oil for a centralized grease lubrication bearing belongs to the technical field of hot rolling equipment. The utility model provides a joint which can manually supply oil to the centralized grease lubrication system without detaching the joint. The technical scheme is that the joint is a tee joint, wherein one connector is connected with a bearing base joint, another connector is connected with a centralized grease lubrication pipeline and a third connector is matched with an oil filling connector for supplying oil. A check valve for supplying oil on the direction of the bearing base is arranged at the joint. The utility model has the advantages that the oil can be supplied without dismounting the pipe joint. When the oil is needed to be supplied manually, the work efficiency can be greatly improved and the overhaul time can be shortened. When the rotor cannot rotate caused by the lubrication fault in the production process, such as grease degeneration, pipeline leakage, and the like, the on-line oil supplement can be realized without manually operation by just hanging an oil feeding device on the joint from a steel clearance.
Description
Technical field
The utility model relates to the pipe coupling to a kind of roller bed bearing seat make-up oil of hot rolling line, belongs to the equipment of hot rolling technical field.
Background technique
In smelter, hot rolling mill roller-way bearing much more lubricated adopts centralized grease lubrications, and centralized grease lubrication generally can be satisfied usage requirement for the good roller-way of working environment.But smelter has quite a few roller-way working environment more abominable, bears bigger impact as the roller-way in roughing zone; Flying shear front roller-way and strip edge heater roller-way bear higher temperature again; Speed is fast during the work of laminar flow cooling roller bed, oil consumption is high; In cold roller back flow side bearing support have the phenomenon of water inlet again, find that grease is smelly rotten in some roller-way when overhauling manual repairing.In these cases, roller-way centralized grease lubrication meeting is subjected to bigger influence, and the modal oil mass that is the centralized grease lubrication system provides can not satisfy the use needs, finally can cause bearing to damage because of lubricating grease is rotten, has a strong impact on production.Therefore, each maintenance has to above roller-way is checked, carries out manual repairing in case of necessity.Traditional manual oil supplement method is earlier pipe joint to be pulled down, and fuelling coupling is connected with the bearing support joint again, after oiling finishes, original joint is installed again.Be connected with hard tube because the bearing support upper connection is most of, it is difficult that dismounting is installed easily, fragile in installation process, also infiltrates the bearing support foul easily, damages bearing, overhauls one of only repairing at every turn and just waste a large amount of time.Therefore, traditional manual oil supplement method is badly in need of improving.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of joint that pipe joint can carry out artificial repairing to the bearing of concentrating drier oil system fuel feeding that can need not to dismantle.
The technological scheme that solves the problems of the technologies described above is:
A kind of joint of being convenient to the repairing of centralized grease lubrication bearing, it is a tee union, joint has three interfaces, an interface is connected with bearing support, another interface is connected with the centralized grease lubrication pipeline, the fuelling coupling of the 3rd interface and repairing is complementary, at the one-way valve of the oriented bearing support direction of jointing repairing.
The above-mentioned joint of being convenient to the repairing of centralized grease lubrication bearing, the described and corresponding interface of fuelling coupling is a demountable structure, and its end has screw thread and tee union to spin, and the other end matches with fuelling coupling.
The above-mentioned joint of being convenient to the repairing of centralized grease lubrication bearing, the one-way cock of the described jointing that is connected with fuelling coupling is made of valve body, ball and spring, oilhole is arranged on the valve body, the diameter of ball is greater than the diameter of oilhole, one side of ball is embedded on the oilhole of valve body inboard, and spring is pressed against the opposite side of ball.
The utility model does not influence centralized lubrication in process of production, and its advantage is that need not to dismantle pipe joint can refuel: when overhauling the artificial repairing of bearing support, can increase work efficiency greatly, reduce labor strength, shorten the repair time.Because of the bearing lubrication fault, as grease deterioration, pipeline leakage etc., when causing roller not change, only need are suspended to oil-filling device on the joint in mistake steel gap in production process, and the people promptly leaves, and can realize online repairing; Guarantee maintenance man's safety on the one hand, can save the bearing that is about to damage on the other hand to greatest extent, made the roller that does not change recover to rotate, reduced a large amount of dead times.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: fittings body 1, bearing support 2, centralized grease lubrication pipeline 3, valve body 4, ball 5
Embodiment
Show among the figure that the utility model is that 1, one interface of a fittings body is connected with bearing support 2 joints, another interface is connected with centralized grease lubrication pipeline 3, and the 3rd interface is connected with the fuelling coupling of repairing.
The interface that the utility model is connected with fuelling coupling can be the tee union integrative-structure, also can be the branch body structure.Because of the easier installation one-way valve of minute body structure, present embodiment has been introduced a kind of demountable split interface, and an end of this interface has screw thread and tee union to spin, and the other end matches with the oil-filling device of special use.
This interface that is connected with fuelling coupling should be designed to can be from the repairing of trend bearing support direction, and the structure that can outwards not overflow lubricant oil at ordinary times, promptly at the one-way valve of the oriented bearing support direction of jointing repairing.A kind of one-way valve that present embodiment proposes is made of valve body 4, ball 5 and spring, on the valve body 4 oilhole is arranged, and the diameter of ball 5 is greater than the diameter of oilhole, and a side of ball 5 is embedded on the oilhole of valve body 4 inboards, and spring is pressed against the opposite side of ball 5.Drier oil can not overflow from jointing at ordinary times, and spring and ball are equivalent to an one-way valve, and the drier oil of centralized lubrication is entered bearing support 2 by backward stop.When need manually refuel, only need the interface of oil-filling device is suspended on the valve body 4, pressure oil can be opened one-way valve, pressure acts on bearing support end and centralized lubrication pipeline end simultaneously, but centralized lubrication pipeline end pressure is ended by the drier oil distributor, so pressure oil can only enter bearing support 2 and can not enter centralized lubrication pipeline 3, this point is vital for application of the present utility model.
The utility model does not influence centralized lubrication in process of production, when overhauling the artificial repairing of bearing support, can increase work efficiency greatly, reduces labor strength, shortens the repair time.Because of the bearing lubrication fault, as grease deterioration, pipeline leakage etc., when causing roller not change, only need are suspended to oil-filling device on the joint in mistake steel gap in production process, and the people promptly leaves, and can realize online repairing; Guarantee maintenance man's safety on the one hand, can save the bearing that is about to damage on the other hand to greatest extent, made the roller that does not change recover to rotate, reduced a large amount of dead times.
A using effect of the present utility model shows, when laminar flow cooling 1# roller-way back flow side bearing is refueled, owing to be subjected to the restriction of field position, with the most skilled workman, recover to need 60 minutes from refueling to, and only needed finish in 1 minute with this joint oiling, efficient can improve 60 times.
