Description
Technical field
The utility model belongs to the technical field of development machine parts, is specifically related to a kind of full-sealing device of not shrinking structure tunnelling machine cutting portion.
Background technique
In recent years, in the face of the more and more fierce development machine market of competition, each manufacturer is in order to occupy favourable position in the market of fierceness, in the research and development of development machine with make and constantly carrying out innovation and improve, so that the quality of product of development machine and technical merit constantly be improved, thereby satisfy the demand of different user.
Development machine is in practical work process, because cutterhead and the cantilever segment of cutting portion relatively rotate, so the design of the motive sealing between the two is difficult point and the focus of the research and development of development machine always.The main employing floating seal of Present Domestic is realized sealing, because the restriction of the operating conditions of development machine causes greatly shorten the working life of floating seal.So Some Domestic development machine manufacturer has increased full-sealing device between cutterhead and cantilever segment, stop pollutant as far as possible, prolong the working life of floating seal.All there is complicated structure in full-sealing device in the market, the phenomenon that using effect is undesirable.
Summary of the invention
Problem to be solved in the utility model is that the prior art full-sealing device all exists the undesirable phenomenon of complicated structure using effect, a kind of full-sealing device of novel tunnelling machine cutting portion is provided, it can stop entering of pollutant, prolongs the working life of inner each component of cutting portion.
For achieving the above object, the technological scheme taked of the utility model is:
A kind of full-sealing device of novel tunnelling machine cutting portion, comprise first sealing, second sealing and three seals, the first sealing by outer cylinder body, be enclosed within the outer cylinder body outside steel plate, be enclosed within the hold-down ring in the steel plate outside and be arranged on steel plate and the body of the cutting head rearward end between the carbon fiber packing consist of; Second sealing by the floating seal frame that is arranged on the outer cylinder body front end, be arranged on floating seal seat between floating seal frame and the body of the cutting head, be arranged on the floating seal between floating seal frame and the floating seal seat and the seal ring that is arranged on outside the floating seal consists of; Three seals is made of the radially oil sealing that is arranged between floating seal frame and the floating seal seat, and radially oil sealing is positioned at the floating seal rear.
Described steel plate is wear-resisting steel plate.
Described hold-down ring is fixedly connected with by connecting bolt with the body of the cutting head rear end.
Described seal ring is V-shaped seal ring.
The utility model forms peripheral seal by carbon fiber packing, steel plate and hold-down ring, in order to stop entering of large block pollutant; Form inner sealing by V-type circle, floating seal, floating seal frame and floating seal seat, in order to stop the intrusion of small particles of pollution thing and water; Form three seals by oil sealing radially, stop pollutant to invade cutting portion inside fully; The utility model seals for the pollutant of different stage respectively, and good sealing effect in order to guarantee the normal operation of cutting portion internal bearings, reduces the fault point of machine.The utility model novelty simple in structure, mounting or dismounting are convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of full-sealing device of novel tunnelling machine cutting portion, comprise first sealing, second sealing and three seals, first sealing by outer cylinder body 1, be enclosed within outer cylinder body 1 outside steel plate 2, be enclosed within the hold-down ring 3 in steel plate 2 outsides and be arranged on steel plate 2 and the body of the cutting head 5 rearward end between carbon fiber packing 6 consist of, steel plate 2 is wear-resisting steel plate, hold-down ring 3 is fixedly connected with by connecting bolt 4 with the body of the cutting head 5, and this place's sealing is mainly used to stop the pollutant of large bulk to enter into cutting portion inside; The second sealing is by the floating seal frame 7 that is arranged on outer cylinder body 1 front end, be arranged on the floating seal seat 8 between floating seal frame 7 and the body of the cutting head 5, the seal ring 9 that is arranged on the floating seal 10 between floating seal frame 7 and the floating seal seat 8 and is arranged on floating seal 10 outsides consists of, seal ring 9 is V-shaped seal ring, this place's sealing is used for stoping the pollutants such as fine particle and water to enter into cutting portion inside, floating seal 10 needs to lubricate in the course of the work, the utility model is provided with the oil filler pipe 14 of floating seal at outer cylinder body 1 internal upper part, outer cylinder body 1 interior bottom increases oil exit pipe 15, also be provided with outlet pipe in the outer cylinder body 1, exhaust pipe structure is identical with oil filler pipe 14 structures, outlet pipe is connected with floating seal 10, outlet pipe has degassing function, guarantee its normal operation, increase the service life; Three seals is made of the radially oil sealing 12 that is arranged between floating seal frame 7 and the floating seal seat 8, radially oil sealing 12 is positioned at floating seal 10 rears, the utility model is increasing radially oil sealing 12 near the bearing place, in order to stop sewage to enter the bearing place, the while also seals the lubricant oil of bearing side.
