Description
Technical field
The utility model belongs to the corollary apparatus technical field of the heading equipment of digging up mine, and relates in particular to a kind of internal spraying closed shell sealing autocompensation installation of cantilevered longitudinal axis development machine.
Background technology
The development machine of mining in the heading equipment, particularly colliery excavation operation adopts the cantilevered longitudinal axis more, development machine in use, internal spraying system plays an important role in atomizing de-dusting.Internal spraying system is by the water spray channel connection on intake tunnel on the water distribution dish and the development machine rotating spindle, because main shaft of boring machine not stall when operation is moving, and need to seal between the inner atomizing inlet system between the water distribution dish, to prevent that high pressure internal spraying water is by revealing away between water distribution dish and development machine rotating spindle.Inner atomizing inlet sealing system originally mostly adopts lattice to come sealing of circle formula or U RunddichtringO to the intake tunnel both sides sealing on the water distribution dish, it is little that this kind hermetically-sealed construction bears pressure, easy to wear, do not have compensation ability after the wearing and tearing of operation a period of time, the internal spraying water leaks serious, can't use.This is to hinder the difficult problem that development machine is realized long-acting internal spraying always.
The utility model content
The purpose of this utility model provides a kind ofly can be carried out effective seal, and can compensate sealing automatically the internal spraying closed shell, guarantees the development machine internal spraying closed shell sealing autocompensation installation of internal spraying system long-term seal.
The technical scheme that the utility model is adopted for achieving the above object is as follows:
A kind of development machine internal spraying closed shell sealing autocompensation installation, comprise the water distribution dish and the airtight and watertight padding of annular, the water distribution dish that it is characterized in that annular is sleeved on the main shaft of boring machine, the two is provided with high water base compound seal packing seal element, the two ends of water distribution dish are provided with the annular cylinder piston and inwardly compress packing seal element, and water distribution dish housing is provided with the passage that communicates with the oil cylinder piston outer cylinder body.
The described passage that communicates with the oil cylinder piston outer cylinder body is equipped with the one way valve pump nozzle outward.
The two ends of described water distribution dish are equipped with seal cover, and seal cover is fixedlyed connected with the water distribution dish, and seal cover seals annular cylinder piston and packing seal element.
The innermost ring of described annular cylinder piston has the bulge loop that cooperates with water distribution dish inwall, the bulge loop of two annular cylinder pistons at water distribution dish two ends with packing seal element to compressing.
Connect on the described water distribution dish cylindrical shell and offer the inner atomizing inlet passage, packing seal element is positioned at the both sides of inner atomizing inlet passage.
Adopt high water base compound seal packing ring as seal on the main shaft of development machine internal spraying closed shell sealing autocompensation installation in the development machine cantilever segment, the two ends of airtight and watertight padding ring add the annular cylinder piston encapsulant are carried out wear-compensating, when main shaft rotates, high water base compound seal packing ring can effectively play sealing function, prevents the leakage of high pressure internal spraying water.After operation a period of time,, squeeze into grease by the pipeline that communicates with the annular cylinder piston/cylinder on the water distribution dish cylindrical shell, promoting annular cylinder moves to the inside, the water base compound seal filler of height is exerted pressure, the compensate for wear part, thus reach the effect that continues sealing.
Beneficial effect of the present invention is, this development machine internal spraying closed shell sealing autocompensation installation is simple in structure, good sealing effect, can effectively seal high pressure internal spraying water, and can effectively compensate the packing seal member on request again simultaneously, guarantee the dust-laying effect that internal spraying uses continuously.
Description of drawings
For making clearer, the clear and definite technology contents of understanding the utility model, the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the cross-sectional view of the utility model embodiment;
Fig. 2 is the user mode cross-sectional view of this development machine internal spraying closed shell sealing autocompensation installation.
The specific embodiment
Seal autocompensation installation mainly by water distribution dish 6 as Fig. 1 to 2 development machine internal spraying closed shell, the airtight and watertight padding ring 5 of water distribution dish 6 and 10 settings of main shaft of boring machine, annular cylinder piston 4, left side sealing lid 1, right sealing lid 3, one way valve pump nozzle 2 is formed, the water distribution dish 6 of annular is sleeved on the main shaft of boring machine 10, connect on water distribution dish 6 cylindrical shells and offer inner atomizing inlet passage 12, ring packing seal 5 is positioned at the both sides of inner atomizing inlet passage 12, water distribution dish 6 housings are provided with the passage 11 that communicates with oil cylinder piston outer cylinder body 4, passage 11 outer assembling one way valve pump nozzles 2.The innermost ring of annular cylinder piston 4 has the bulge loop that cooperates with water distribution dish inwall, the bulge loop of two annular cylinder pistons at water distribution dish two ends with packing seal element 5 to compressing.The two ends of water distribution dish are equipped with left seal cover 1 and right seal cover 3, and left and right sides seal cover is fixedlyed connected by bolt 7 with water distribution dish 6, and seal cover seals annular cylinder piston and packing seal element.
Can earlier the water base airtight and watertight padding ring 5 of height be encased in the water distribution dish 6 during assembling, again with left seal cover 1, right cover 3, annular cylinder piston and " O " type circle 8 and 9 usefulness bolts 6 are contained on the water distribution dish.At last whole sealing autocompensation installation is contained on the development machine rotating spindle 10 outer suit cantilever tube 14, the rear end assembling reductor 13 of cantilever tube.
After operation a period of time, by the one way valve pump nozzle on the water distribution dish, grease is squeezed in the oil cylinder, promote the annular cylinder piston and move, thereby pressure compensation is carried out in water base airtight and watertight padding to height, reaches the long term seal effect along major axes orientation.
