Description
Technical field
The utility model relates to the pick-up unit of big-and-middle-sized ship components, refers more particularly to a kind of pick-up unit being applicable to the stern tube watertight test of big-and-middle-sized boats and ships.
Background technology
The stern tube bow stern of big-and-middle-sized boats and ships has packoff, and in stern tube, stern tube shaft rotates and is generally oil lubrication with bearing friction, and this just requires that stern tube has strict sealing property requirement.Under the condition ensureing the intact and sealing state of stern tube bow stern sealing, the seal request of stern tube body is particularly important.Meanwhile, stern tube endoporus needs interference pressing bearing, and the requirement on machining accuracy of internal control is higher.Therefore, the stern tube needing butt welding to connect before machine work stern tube carries out watertight test, and whether detect stern tube body has Seepage.In testing process in the past, general employing welds something that gives the game away at stern tube two ends, then is placed on inside something that gives the game away with rubber cover plate, with bolt presses cover plate again toward water filling in stern tube, make hydraulic pressure reach 0.2MPa, and pressurize must not have Seepage in 5 minutes.Such detection method, hand labor intensity is large, inefficiency, and sealing top board is difficult to supporting, and adjustment is installed very inconvenient.
Summary of the invention
The purpose of this utility model solves above-mentioned Problems existing.
The utility model is achieved in that big-and-middle-sized marine stern axle tube watertight test pick-up unit, comprise V-type bearing, it is characterized in that: described V-type bearing is shelved with stern tube, stern tube both sides are provided with support, connect by upper and lower two leading screws and fixed by interior tune nut and investigation mission outside the city or town nut between two stands, support level is provided with two and shores bolt, support casing has sealing top board, sealing top board is closely cooperated by the end of shoring bolt and stern tube, the sealing top board of right part is provided with bleeder pipe, the sealing top board of left part is disposed with water inlet pipe from top to bottom, forcing pipe, waterproof plug.
Further, described bleeder pipe, water inlet pipe, forcing pipe, waterproof plug all communicate with the inner chamber of stern tube.
Further, when described stern tube is placed on V-type bearing, the distance at two ends is 1/4 of stern tube.
Further, the height of described stern tube with the centre-height of support for benchmark.
Further, the distance between described sealing top board and support is 50mm.
The utility model simple and convenient, quick, good reliability, the needs of detection type like big-and-middle-sized marine stern axle tube watertightness test can be applicable to, the defect existed in the test process of overcoming over and loaded down with trivial details work, facilitate the stability of product testing, substantially increase the efficiency of Product checking, thus the larger quality that improve product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, V-type bearing, 2, support, 3, sealing top board, 4, shore bolt, 5, bleeder pipe, 6, leading screw, 7, interior tune nut, 8, investigation mission outside the city or town nut, 9, water inlet pipe, 10, forcing pipe, 11, waterproof plug, 12, stern tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, big-and-middle-sized marine stern axle tube watertight test pick-up unit, comprise V-type bearing 1, it is characterized in that: described V-type bearing 1 is shelved with stern tube 12, stern tube 12 both sides are provided with support 2, connected by upper and lower two leading screws 6 between two stands 2 and fixed by interior tune nut 7 and investigation mission outside the city or town nut 8, support 2 has been horizontally disposed with two and has shored bolt 4, support 2 cover has sealing top board 3, sealing top board 3 closely cooperates with the end of stern tube 12 by shoring bolt 4, the sealing top board 3 of right part is provided with bleeder pipe 5, the sealing top board 3 of left part is disposed with water inlet pipe 9 from top to bottom, forcing pipe 10, waterproof plug 11, described bleeder pipe 5, water inlet pipe 9, forcing pipe 10, waterproof plug 11 all communicate with the inner chamber of stern tube 12, when described stern tube 12 is placed on V-type bearing 1, the distance at two ends is 1/4 of stern tube 12, the height of described stern tube 12 with the centre-height of support 2 for benchmark, distance between described sealing top board 3 and support 2 is 50mm.
During concrete enforcement, the first step, set aside in V-type bearing 1 by stern tube 12, should note the distance at two ends when stern tube is placed into V-type bearing 1, its distance is 1/4 place of stern tube 12 length.
Second step, with support 2 centre-height for benchmark, measure stern tube 12 when being shelved on V-type bearing 1, the vertical height on center to the ground of stern tube 12.According to difference in height, select the cushion block of suitable thickness, and carry out point admittedly, fill up height fall.
3rd step, sealing top board 3 to be inserted in support 2, to be pushed into stern tube 12 two ends, one of screw mandrel 6 and interior tune nut 7 are inserted in the hole of a support, then the other end of screw mandrel and interior tune nut 7 are inserted in another bracket holes.Then investigation mission outside the city or town nut 8 is inserted on screw mandrel 6, according to the length of stern tube 12, inside and outside tune nut, apart from 50mm place, is then fixed on support 2 by preliminary adjustment sealing top board 3 to support 2.When adjusting pole 2, should notice that its center is parallel with the Central Symmetry of stern tube 12, note the position of water inlet pipe 9 and bleeder pipe 5 simultaneously.After basic fixed position, shore bolt 4 reply sealing top board and carry out adjustment of exerting pressure, reach substantially identical to the pressure suffered by stern tube 12.
4th step, open bleeder pipe 5 and water inlet pipe 9 carries out water filling, until fill water in cylindrical shell.Close bleeder pipe 5 and water inlet pipe 9, open press pump and continue water filling and be forced into after inner pipe water pressure reaches 0.2MPa and stop pressurization.Pressurize 5 minutes, looks into and sees if there is seepage defect.1-2 repair welding is allowed for pole individual defects, again should carry out tightness test after repair welding, and will be up to the standards.After watertight test passes, open drain plug 11 and bleed off water in cylindrical shell, so just can complete a watertight test cycle.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; some improvements and modifications can also be made; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each ingredient not clear and definite in the present embodiment is realized.
In sum, big-and-middle-sized marine stern axle tube watertight test structure of the detecting device described in the utility model is simple, easy to assembly, sensing range is wide, long service life, safe and reliable, the defect existed in the test process of overcoming over and loaded down with trivial details work, facilitate the stability of product testing.
