Abstract
The utility model discloses an automatic shield of make -up oil constructs quick -witted hobbing cutter, including the main shaft, offered oil duct, oil pocket and screw in the main shaft, be provided with the plug in the screw, the oil duct communicates with each other with the hobbing cutter bearing, and the oil pocket lies in between oil duct and the screw, and the internal diameter of oil pocket is lighter than the internal diameter of screw, be provided with the oil storage cavity of making by flexible material in the oil pocket, oil storage cavity upper portion is provided with the oil -out of oil inlet and silica gel valve structure. The technical problems to be solved in the utility model are can according to the automatic make -up oil of the size of the pressure in the oil pocket, the efficiency of construction that the shield constructs the machine have been improved at the lubricating oil in -process that heaies up by a wide margin.
Description
Technical field
The utility model relates to shield machine field, relates in particular to a kind of shield machine roller cutter of automatic make-up oil.
Background technology
The hobboing cutter of shield machine is arranged on rotating cutter-head, has coordinated the construction such as tunnel excavation, driving with other cutter.In use procedure, hobboing cutter needs lubrication, and existing lubricating arrangement mainly encapsulates lubrication oil in hobboing cutter inner chamber, and inner chamber arranges fuel feed hole, and fuel feed hole is by plug shutoff.But hobboing cutter can produce a large amount of heats in rotary cutting rock process, in inner chamber, therefore the temperature of lubrication oil can constantly rise, interior cavity pressure increases thereupon, when exceeding the sealing load in inner chamber when pressure, system there will be leakage, and then causes hobboing cutter because of can not normally rotary cutting and premature failure.
In order to solve the problems of the technologies described above, in prior art, propose following technology:
As China Patent No. " 201020230402.8 " to disclose the lubricating arrangement of shield machine roller cutter on January 5th, 2011, its technical scheme comprises the screw of spinning plug, oil pocket for being communicated with cutter bearing by fuel feed hole in screw, feature is the end that screw is arranged on main shaft, and the bottom of screw is provided with rubber pad; The outer end of plug is provided with spinning hole, and the inner is provided with inner chamber, and the two is communicated by small through hole.But in actual application, owing to can consume a certain amount of lubrication oil in hobboing cutter rotary cutting process, but this lubricating arrangement can not supplement self-lubricate oil again, this just causes needing frequent shutdown to augment lubrication oil, significantly reduces efficiency of construction.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, a kind of shield machine roller cutter of automatic make-up oil is provided, the technical problem that the utility model solves is can in lubrication oil temperature-rise period, according to the automatic make-up oil of pressure size in oil pocket, significantly improve the efficiency of construction of shield machine.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of shield machine roller cutter of automatic make-up oil, comprise main shaft, oil duct, oil pocket and screw is offered in main shaft, plug is provided with in screw, oil duct communicates with cutter bearing, and oil pocket is between oil duct and screw, and the internal diameter of oil pocket is less than the internal diameter of screw, it is characterized in that: be provided with the oil storage cavity be made up of flexible material in described oil pocket, described oil storage cavity top is provided with the oil-out of oil-in and silica gel valve structure.
Be provided with seal head in described oil pocket, the two ends of described seal head are fixedly connected with oil storage cavity with plug respectively.
Described oil storage cavity is chondritic.
Employing the utility model has the advantage of:
One, the oil storage cavity in the utility model is made up of soft material; automatically oil storage cavity is extruded when this structure can raise at lubricating oil temperature (i.e. pressure increase in oil pocket); and make the lubrication oil in oil storage cavity automatically add in oil pocket by oil-out; can either solve because lubrication oil expands with heat and contract with cold a series of leakage problems brought; again can power generating ratio number of times, thus significantly can improve the efficiency of construction of shield machine.In addition, oil-out adopts silica gel valve structure, is conducive to lubrication oil in oil storage cavity not leaking without maintenance during pressure.
Two, in the utility model, the two ends of seal head are fixedly connected with oil storage cavity with plug respectively, and this structure is conducive to Fast Installation and the dismounting of plug, seal head and oil storage cavity.
Three, in the utility model, oil storage cavity is set to chondritic, is conducive to improving oil storage cavity to the sensitivity of stress reaction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Be labeled as in figure: 1, main shaft, 2, oil duct, 3, oil pocket, 4, plug, 5, cutter bearing, 6, oil storage cavity, 7, oil-in, 8, oil-out, 9, seal head.
Detailed description of the invention
A kind of shield machine roller cutter of automatic make-up oil, comprise main shaft 1, oil duct 2, oil pocket 3 and screw is offered in main shaft 1, plug 4 is provided with in screw, oil duct 2 communicates with cutter bearing 5, and oil pocket 3 is between oil duct 2 and screw, and the internal diameter of oil pocket 3 is less than the internal diameter of screw, be provided with the oil storage cavity 6 be made up of flexible material in described oil pocket 3, described oil storage cavity 6 top is provided with the oil-out 8 of oil-in 7 and silica gel valve structure.
In the utility model, be provided with seal head 9 in described oil pocket 3, one end of described seal head 9 is weldingly fixed on plug 4, other end connection bonding with oil storage cavity 6.
In the utility model, described oil storage cavity 6 is preferably chondritic, but is not limited to above-mentioned preferred embodiment, such as, can also be oval structure, column structure and cone barrel structure etc.
In the utility model, the oil-out 8 of described silica gel valve structure is known prior art, identical with silica gel valve Bottle cap structure, when without ambient pressure, the lubrication oil in oil storage cavity 6 can be kept not leak.
In the utility model, described flexible material preferably has the material of superior heat resistance, wear-resisting and antiseptic property.
In the utility model, during hobboing cutter work, lubricating oil temperature raises, and pressure increase in oil pocket 3 also extrudes oil storage cavity 6, and after being squeezed, the lubrication oil in oil storage cavity 6 is automatically spilled in oil pocket 3 from the oil-out 8 of silica gel valve structure and supplements oil pocket 3.
