Description
Technical field
The utility model relates to the cutting unit of a kind of development machine, specifically relates to a kind of internal spraying formula tunneling machine cutting portion.
Background technology
Usual tunneling machine cutting portion is made up of step-down gear, cantilevered member, cutting head, motor and motor rack five major part, and cutting head internal spraying is drilled with the hydrophthalmia of about 12 usually, it is achieved the effect of internal spraying depositing dust and cooling pick. Due to the structural limitations in tradition tunneling machine cutting portion, internal spraying waterway seal structure adopts to arrange sealing-ring form on main shaft in cantilevered member and seal, owing to the diameter of main shaft is relatively big, adopt the effect of sealing-ring sealing water not good, cause the internal spraying pressure can not more than 3Mpa. But have the dust of more than 85% to be respirable dust (dust granules < 0.7 ��m) in tunnel, down-hole, when only hydraulic pressure reaches more than 8Mpa, these respirable dusts could be played effective dust-laying effect, above-mentioned tradition structure the operation of tunneling machine cutting portion time produce a large amount of respirable dusts can not get effective process, the healthy of field personnel can be caused bigger infringement.
Practical novel content
The respirable dust produced can be carried out effective depositing dust process when the technical problems to be solved in the utility model is to provide a kind of operation such that it is able to avoid field personnel to be subject to respirable dust infringement and damage healthy internal spraying formula tunneling machine cutting portion.
For solving the problems of the technologies described above, a kind of internal spraying formula tunneling machine cutting portion of the utility model, comprise cantilevered member and cutting head, on the excircle of cutting head, helically mode is equipped with pick, cantilevered member is connected with retarding mechanism built with main shaft, one end of main shaft, described cutting head one end be circumferentially connected with ring gear by bolt, the other end of described main shaft is matched with ring gear by satellite gear, is fixed with planet wheel shaft in satellite gear; Described cantilevered member comprises the arm cylinder section being positioned at cutting head outside and the cantilever shafts section being placed in cutting head inside, cantilever shafts section is equipped with cantilever bearings, the bearing bowl cover and bearing cup that are connected by joint bolt are housed outside cantilever bearings, it is located by connecting by tack bolt between the top of bearing bowl cover and the top of described cutting head, room, ring seal chamber it is formed with between described bearing bowl cover and the inwall of bearing cup and described cutting head, the outer side seal of described ring gear is equipped with ring gear gland, and the two ends of described planet wheel shaft are separately fixed in described bearing cup and arm cylinder section; It is provided with water entry in described cantilever shafts section, water entry is connected with water inlet pipe, the water inlet connecting passage being connected with described water entry is offered at the top of described bearing bowl cover, the stifled head of the water inlet linked up with described water entry and sealing gland are sequentially housed in water inlet connecting passage, it is arranged with V-type combined seal ring outside the stifled head of water inlet, sealing gland is set in outside the stifled head of water and compresses V-type combined seal ring, sealing gland has water exit, and described bearing bowl cover has room, the ring seal chamber water entry being connected with water exit.
As improvement of the present utility model, the bottom of described tack bolt is provided with pit, and pit is resisted against the top of described sealing gland built with compression spring, the other end of compression spring.
As further improvement of the utility model, the room, ring seal chamber formed between described bearing bowl cover and the inwall of bearing cup and described cutting head may extend to cutting head near the termination of arm cylinder section one end.
Adopt the internal spraying formula tunneling machine cutting portion of said structure, when carrying out excavation operation, motor is connected with the retarding mechanism in the utility model tunneling machine cutting portion, retarding mechanism drive shaft is rotated, main shaft drives described ring gear to rotate by the satellite gear matched, ring gear and then drive described cutting head to rotate, and then reach the object cut and cut rock stratum, driving. it is adopt to be provided with water entry in the cantilever shafts section being placed in cutting head due to water route of the present utility model structure, the water inlet connecting passage being connected with water entry has been offered at bearing cup tops, and sequentially it is equipped with into the stifled head of water and sealing gland in water inlet connecting passage, it is arranged with V-type combined seal ring outside the stifled head of water inlet, sealing gland is set in outside the stifled head of water and compresses the technology feature of V-type combined seal ring, what therefore the internal diameter of water entry can be processed is very little, in the stifled head of corresponding water inlet, it is very little that external diameter all can be processed, therefore can be realized the stifled excellent sealing between head and bearing bowl cover of water inlet by V-type combined seal ring described in the pressure effect of sealing gland. even if described V-type combined seal ring still can realize the stifled excellent sealing between head and bearing bowl cover of water inlet when intake pressure reaches more than 8Mpa after testing, there will not be the phenomenon that water is flowed in cantilever bearings, therefore the utility model can make the intake pressure of cutting unit bring up to more than 8Mpa, corresponding cutting head portion nozzle hydraulic pressure also can reach more than 8Mpa, can realize the most effective depositing dust process of respirable dust is alleviated respirable dust to greatest extent to the infringement of people's health. the room, ring seal chamber of the described bearing bowl cover in the utility model and formation between the inwall of bearing cup and described cutting head can extend near the termination of cutting head in addition, therefore nozzle can be provided with near each pick of cutting head, it is possible to reach better dust-laying effect and pick cooling-down effect.
