Abstract
The invention relates to a full-sealing device for a cutting component of a roadheader, wherein the full-sealing device is of a non-telescopic structure. The novel full-sealing device comprises a first seal, a second seal and a third seal. The first seal is formed by an outer cylinder, a steel plate, a clamp ring and a carbon fiber packing, wherein the outer cylinder is sleeved with the steel plate, the steel plate is sleeved with the clamp ring, and the carbon fiber packing is arranged between the steel plate and the rear end of a cutting head. The second seal is formed by a floating sealing frame, a floating sealing base, a floating seal and a sealing ring, wherein the floating sealing frame is arranged at the front end of the outer cylinder, the floating sealing base is arranged between the floating sealing frame and the cutting head, the floating seal is arranged between the floating sealing frame and the floating sealing base, and the sealing ring is arranged on the outer side of the floating seal. The third seal is formed by a radial oil seal arranged between the floating sealing frame and the floating sealing base, and the radial oil seal is located at the back of the floating seal. According to the full-sealing device, pollutants are sealed according to different ranks, the sealing effect is good, normal running of bearings in the cutting component is guaranteed and trouble spots of a machine are reduced, and the full-sealing device is simple in structure and convenient to assemble and disassemble.
Description
Technical field
The invention belongs to the technical field of development machine parts, be 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 in order to occupy favourable position in fierce market, in the research and development of development machine with manufacture and constantly carrying out innovation and improving, quality of product and the technical merit of development machine are constantly improved, thereby meet the demand of different user.
Development machine is in practical work process, because cutterhead and the cantilever segment of cutting portion relatively rotates, 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, and the restriction due to 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, stops pollutant as far as possible, extend 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 by this invention is that 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, extends the working life of inner each component of cutting portion.
For achieving the above object, the technological scheme that the present invention takes is:
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, be enclosed within outer cylinder body outside steel plate, be enclosed within the hold-down ring in steel plate outside and be arranged on steel plate and the body of the cutting head rearward end between carbon fiber packing form; Second sealing by be arranged on outer cylinder body front end floating seal frame, 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 floating seal seat and the seal ring that is arranged on outside floating seal forms; Three seals consists of the radially oil sealing being arranged between floating seal frame and floating seal seat, and radially oil sealing is positioned at 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 present invention forms peripheral seal by carbon fiber packing, steel plate and hold-down ring, in order to stop entering of large block pollutant; By V-type circle, floating seal, floating seal frame and floating seal seat, form inner sealing, in order to stop the intrusion of small particles of pollution thing and water; By oil sealing radially, form three seals, stop pollutant to invade cutting portion inside completely; The present invention 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 present invention's novelty simple in structure, installs and disassembles conveniently, and using effect is obvious.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
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 form, 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, 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 floating seal seat 8 and is arranged on floating seal 10 outsides forms, 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 present invention is provided with the oil filler pipe 14 of floating seal at outer cylinder body 1 internal upper part, the interior bottom of outer cylinder body 1 increases oil exit pipe 15, in outer cylinder body 1, be also provided with outlet pipe, 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 that it normally moves, increase the service life, three seals consists of the radially oil sealing 12 being arranged between floating seal frame 7 and floating seal seat 8, radially oil sealing 12 is positioned at floating seal 10 rears, the present invention is increasing radially oil sealing 12 near bearing place, in order to stop sewage to enter bearing place, also the lubricant oil of bearing side is sealed simultaneously.
During specific works of the present invention, cutter head shaft 13 drives the body of the cutting head 5 to rotate by spline on the one hand, and the body of the cutting head 5 is by set bar 11 and drive floating seal seat 8 synchronously to rotate; Together with on the one hand outer cylinder body 1 is bolted on floating seal frame 7, keep static, this two aspect forms relative movement, for guaranteeing that internal bearings avoids polluting, increases seal arrangement between the two, guarantees the normal work of cutting portion internal bearings.
The invention is not restricted to above-described embodiment; the various obvious modifications and variations of carrying out are to be understood that those skilled in the art can carry out the suitable new embodiment that is combined to form to the parts that relate in above-described embodiment, within all should fall into protection scope of the present invention on the basis that does not depart from the principle of the invention.
