Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further described.
As shown in Figures 1 to 4, the universal fair leader of minimizing boats and ships steel rope abrasion described in the utility model, comprises body skin 1, inner housing 2, baffle ring 3, clamping plate 4, nylon pulley 5, contact roller 6, nylon roller 7, bolt 8, packing ring 9, spring chair 10, bolt 11, nut 12, latch 13, base 14, first web 15 and the second web 16.Concrete structure and annexation are:
As shown in Fig. 1,2,6, described first web 15 and the second web 16 are symmetrically welded at base 14 edge, become the support of whole device.Body skin 1 axially vertical being welded on the first web 15 and the second web 16, forms the fixed housing of whole fairlead.
As shown in 1,2,5, described two clamping plates symmetry is placed and fixes, and front going out clamping nylon pulley 5 in eccentric end place under end, use bolt 11, nut 12 fix nylon pulley pivot pin; At nylon pulley 5 top clamping contact roller 6, with latch 13 as contact roller 6 pivot pin; Clamping plate 4 other end welds with inner housing 2 inner circle, and the done circumference forming fairlead rotates kernel in relative rotation.
As shown in Figure 1, described rotation kernel is with inner housing 2 axially for benchmark, and entirety is inserted among the body skin 1 of fixed housing, and uses nylon ball contact outside inner housing 2 with inside body skin 1, ensures that inner housing 2 freely makes relative circular-rotation with body skin 1.
The housing two ends of described body skin 1, use bolt 8, packing ring 9 and spring chair 10 fix a circular baffle ring 3, the axial motion of restriction inner and outer shell.
Boats and ships steel rope stitches from hole reserved between nylon pulley 5 and contact roller 6 and imports, and produces friction of rolling with nylon pulley 5, through connecting upper winch after inner housing 2.Nylon pulley 5 is connected as a whole with inner housing 2, nylon pulley 5 is after steel rope is subject to pulling force, nylon pulley 5 at lineoutofservice signal pull point under pressure effect, drive inner housing 2 to do to rotate to dividing to the direction of pressure body skin 1 in, maintenance steel rope is orthogonal all the time with nylon pulley 5.
The assembly method of the universal fair leader of described minimizing boats and ships steel rope abrasion: before assembling, first the first web 15 and the second web 16 are equidistantly welded meeting under spacing dimension requirement with base 14 respectively, again the first web 15 and the second web 16 are equidistantly welded with body skin 1, ensureing the welding carrying out inner housing 2 and clamping plate 4 under body skin 1 unlikely generation welding deformation and the constant prerequisite of two clamping plates 4 spacing dimension; After inner housing 2 has welded with clamping plate 4, then inner housing 2 outside face and nylon roller 7 contact portion are processed; Then nylon pulley 5 and clamping plate 4 are assembled, reprocessing axis hole, installs contact roller 6 subsequently; Baffle ring 3 is installed to body skin 1 two ends, finally complete the last assembling of universal fair leader, debugging, universal fair leader is installed on the existing chock position of large ship.
Use material is:
Except nylon pulley 5 is with except nylon ball 7, remaining part is steel.Clamping plate are by being of a size of 850*500*30mm and having steel plate cutting processing " Г " shape of sufficient intensity to form.Inner housing is processed by the steel pipe being of a size of Φ 480*32*450mm, and body skin is by the steel pipe being of a size of Φ 402*22*490mm, and web is triangular steel plate, and material specification is required to meet requirement of strength.
Principle of work and process:
As shown in Figure 1, 2, 3, before carrying out receipts anchor operation windlass, need first to extract universal fair leader latch 13, take off contact roller 6, can start normally to receive steel rope, finally make anchor fluke hook and go up on the quarter, complete the operation of receiving anchor; When carrying out putting anchor ship's fix, first make the windlass on large ship be in and put anchor-shaped state, hold after anchor to be taken to the position of specifying by anchor with the windlass of weighing anchor on ship again and cast anchor, after having thrown anchor, the universal fair leader contact roller 6 taken off is loaded onto again, and put on latch 13, steel rope can be tightened up and complete the work of casting anchor.
As shown in Figure 3,4, when anchor received by boats and ships windlass, due to steel wire penetrating universal fair leader inner housing 2, steel rope cannot take out from universal fair leader, so directly whole anchor cannot be pulled on deck with windlass.Need first anchor to be played to weigh anchor on ship, then from ship of weighing anchor, anchor is hung large ship, namely need anchor to be hung on deck by other suspenders.
As shown in Figures 1 to 4, universal fair leader can cause nylon roller 7 to wear and tear in use for some time, and particularly pressure side wearing and tearing are larger.As comparatively large in the wearing and tearing of nylon roller 7 pressure side, nylon roller 7 pressure side and not pressure side can be exchanged.Note adding butter lubrication proper time, and prevent from intaking between body skin 1 and inner housing 2.
