Accompanying drawings 1 to Fig. 3.
Embodiment 1
Turning gland assembly after a kind of cutter suntion dredger, is characterized in that: turning gland assembly is made up of top straight tube 1, upper bend pipe 2, stuffing-box 3, lower bend pipe 4, base 5, support 6, stiffener 7, backplate 8, oil pipe.Stuffing-box 3 is by pipe in stuffing-box 3.1, gland 3.2, stuffing-box outer tube 3.3 and form silk 3.4, filler is had between pipe 3.1 and stuffing-box outer tube 3.3 in stuffing-box, there is the gland 3.2 compressing compacting filler at middle part, gland 3.2 by silk 3.4 and stuffing-box outer tube 3.3 tight.Between upper bend pipe 2 and lower bend pipe 4, stuffing-box 3 is housed, base 5 is equipped with in lower bend pipe 4 bottom, and base 5 is installed on the frame 6; Bottom upper bend pipe 2, lower bend pipe 4 top, stuffing-box 3 center line consistent with base 5 center line.Lower bend pipe 4 side is provided with discharging valve 9.Support 6 is provided with backplate 8 and stiffener 7, and backplate 8 on the frame 6 portion is used for fixing upper bend pipe 2, and stiffener 7 is for being directly welded and fixed at deck sides.Base 5 is provided with the oil pipe that daily oiling is safeguarded.
The design process of the present embodiment:
1, the finished product after making must meet mounting condition, namely turning gland lower bend pipe center line must with the waterborne tube hub lines matching of frame on floating drum, can not be partially too high or partially too low.Partially too high, to improve when pipe waterborne is installed, cause the lower flange of its flange and turning gland not parallel, difficulty is installed; Partially too low, float buoyancy is large, and pipe waterborne cannot be depressed into setting height(from bottom), and either way can cause the phenomenon of stuffing-box eccentric wear above, reduces the application life of turning gland.
2, based on pipe waterborne, turning gland detailed dimensions is calculated.
The 2.1 calculating waters surface are 200mm to floating drum pipe distance from bottom waterborne, and known pipeline internal diameter 500mm, wall thickness 8 ㎜ obtain the water surface to tube hub linear distance d1=458mm waterborne.
2.2 calculate the water surface to limit pontoon deck distance.According to fuel oil tank refuel 50% time, ship Mean Draught is that 1000mm calculates, and limit buoyancy tank type height 2200mm, obtaining the water surface to the distance of limit pontoon deck is d2=1200mm.
On 2.3 known decks, mud pipe center line is d3=1870mm to limit pontoon deck distance, and obtaining the water surface to deck mud pipe distance between center line is d4=d2+d3=3070mm.Under supposing turning gland, bend pipe docks with pipe waterborne is complete, obtains bend pipe center line extremely lower bend pipe distance between center line d5=d4-d1=2612mm on turning gland.
2.4 add the height of upper bed-plate according to the turning gland of ideal length d5, and a part for base can not be able to be welded below the water surface, so need d5 to shorten.Because this turning gland adopts packing box seal, so will ensure that packing gland has certain up and down distance when shortening the length of d5, be convenient for changing stuffing-box.In sum, the distance between center line of elbow up and down of turning gland finally shortens to d6=2200mm.Elbow flange makes according to GB: flange outer diameter 670mm, 20 screws, and the diameter in hole is 27mm, hole center to center distance 620mm.
After 2.5 overall dimensions settings, consider that later maintenance is changed conveniently, when designing stiffener, the form that outside adopts bolt fixing, remainder and Hull Welding, such be designed to after spot replace turning gland assembly reduce a lot of operation, saved the repairing time.
3, top length of straight pipe is decided to be 1500mm, during in-site installation elbow assembly, according to actual conditions cutting.
When 4, designing top straight tube two end flanges, wherein will survive flange in one end, during convenient installation, aim at screw.The flange of mud pipe is nonstandard size, and hole center to center distance is 610mm, and other are measure-alike, therefore straight tube two ends flange size is different.
5, turning gland is fixed on hull by support, and the particular location that support is fixed on turning gland stiffener needs to weld at the scene.Backplate plays the effect of fixing upper bend pipe, and base can also have the function of rotation while supporting upper and lower bend pipe and stuffing-box, the less resistance of the rotation for stuffing-box assembly.
6, the hatchcover on the buoyancy tank of limit is to the distance at edge, if be greater than the length of frame bottom, stiffener is directly welded on deck sides; If but be less than, can space be left between turning gland stiffener and hull, the steel plate repair welding that this part available 2 pieces of 10mm is thick, reach and support fixing effect.
7, conveniently the daily oiling of base vertical shaft is safeguarded, ad hoc meter oil pipe leads to deck from vertical shaft, and is fixed on stiffener edge.
8, under turning gland, a discharging valve is installed in bend pipe side, dismantles dredge pump or can play two kinds of effects when drawing dredge pump: one is prevent from the water in mud pipe from pouring in down a chimney to meet accident; Two is reduce the water yield entered in cabin.
The installation process of the present embodiment:
Be not the midline at limit buoyancy tank when 1, this part is installed, should move towards consistent with mud pipe on ship.
2, first carry out the center centering of spoil disposal straight tube on top straight tube and deck during this part integral installation, the centering of non-standard flange screw, ensure concentric position, bolt connects unstressed generation.
3, the first spot welding of stiffener and backing positions is fixed, and finds full weld after the link position of lower bend pipe and floating drum pipe waterborne accurately.
4, postwelding is fixed appropriate, connects top straight tube and boats and ships mud pipe, ensures connection and the proper seal of flange.Now, rotate this part lower end and round end, whether flexibly rotatablely observe, whether have torsional deformation part.
5, contrast the distance between stiffener and limit buoyancy tank, cutting steel plate welds.
6, finally install and connect bend pipe and buoyancy aid mud pipe (being connected by flexible pipe between steel pipe) under this part.
7, regular maintenance, base and stuffing-box need periodic maintenance to ensure to rotate smooth and easy.Whether the rotating part of the rotating part and base of making regular check on pipeline rotates flexibly and rust staining rusty stain processes in time as found.
The present embodiment has and coordinates auxiliary cutter suntion dredger dredging operation, realizes water borne conduit by the impact of trend and wind direction, freely swings and do not form dog leg, easy for installation, 180 ° of rotations, safeguards the good effects such as simple.The present invention can improve the efficiency of cutter suntion dredger dredging operation, obtains good dredging benefit, and can be applied on other similar engineering boats and ships.
