Technical field

The utility model belongs to the winch for ship technical field of ship and ocean, and in particular to a kind of underwater fairlead, For changing ice level ship navigation damping mechanism.

Background technology

Ice level ship is the ship that can be navigated by water in ice condition to a certain degree by classification society's classification rules and working condition requirement.Lead cable Device is in order that hawser leads to outboard from inboard leads to harbour or other heaving pile places, changes the direction of hawser, limits it and lead Out position and the device for reducing hawser abrasion.Underwater fairlead is by rolling wheel support, roller, roller shaft, swing in the prior art Seat, fixing axle, rotary pin shaft and upper lower fixed seat etc. form, and are fixedly mounted on below platform (ship) hull outside, usual work Positioned at underwater when making.Existing fairlead is fixedly mounted on below water line, in polar region during platform (ship) navigation of effect Because seawater surface freezes, cause fairlead and ice sheet contact squeeze and increase ship resistance, and fragile fairlead structure Part.

Utility model content

Technical problem to be solved in the utility model is in view of the shortcomings of the prior art, there is provided a kind of service life length Underwater fairlead, for changing the damping force during navigation of ice level ship.

In order to solve the above technical problems, a kind of underwater fairlead of the utility model, including pulley, pulley spindle, pulley branch Seat, retaining mechanism, swing seat, fixing axle, upper fixed seat and lower fixed seat, fixed seat and lower fixed seat are fixed on up and down Profile；The swing seat is fixed on fixed seat and lower fixed seat, the fixed number of axle be two, described two One end of root fixing axle is each attached in the swing seat, and the other end is separately fixed on fixed seat and lower fixed seat, The pulley support is connected by rotary pin shaft with swing seat；The pulley is assembled on pulley support by pulley spindle；It is described The quantity of retaining mechanism is two groups, is separately positioned on the swing seat both ends, and the retaining mechanism is used for the pulley after upset Bearing is locked in the swing seat.

Further, the pulley support is spun upside down by rotary pin shaft, and flip angle is around rotary pin shaft Upward 55 ° and downward 55 °.

Further, two fixing axles are setting up and down and parallel with profile.

Specifically, the outer rim of the pulley is provided with the groove for being used for hawser motion.

Further, the swing seat can be swung, and the maximum amplitude of oscillation is ± 90 °.

Further, the material of the pulley spindle is 2Cr13.

The beneficial effects of the utility model are：The underwater fairlead of the utility model is simple in construction, and maintaining is convenient, will The single fixed form of fairlead is changed to movable, changes the position of underwater fairlead, because of sea when solving the navigation of ice level ship Water surface icing fairlead and ice sheet contact squeeze and the problem of increase ship resistance, extend the use of underwater fairlead Life-span.

Embodiment

The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described Embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all belongs to In the scope of the utility model protection.

In specific embodiment of the utility model, as shown in Figure 1 to Figure 2, the utility model specifically discloses a kind of water Lower fairlead, including pulley 1, pulley spindle 2, pulley support 3, retaining mechanism 4, swing seat 5, fixing axle 6, the and of upper fixed seat 8 Lower fixed seat 9, fixed seat 8 and lower fixed seat are fixed on profile about 9；

The both ends of swing seat 5 are separately fixed on fixed seat 8 and lower fixed seat 9, and the quantity of fixing axle 6 is Two, two fixing axles 6 are setting up and down and parallel with profile, and one end of two fixing axles is each attached to In the swing seat 5, the other end is separately fixed on fixed seat 8 and lower fixed seat 9,

The pulley 1 is assembled on pulley support 3 by pulley spindle 2, and the outer rim of the pulley 1, which is provided with, is used for hawser motion Groove, the pulley support 3 is connected by rotary pin shaft 7 with swing seat 5, and the pulley support 3 is carried out around rotary pin shaft 7 Lower upset, flip angle are around 7 upward 55 ° of rotary pin shaft and downward 55 °；

The quantity of the retaining mechanism 4 is two groups, is separately positioned on the both ends of swing seat 5, the retaining mechanism 4 is used for Pulley support 3 after upset is locked in the swing seat 5.When pulley support 3 is swung up 55 °, retaining mechanism 4 will be sliding The fulcrum of the top of wheeling support 3 is locked at the upper end of swing seat 5, and when pulley support 3 is to 55 ° of lower swing, retaining mechanism 4 is by pulley branch The fulcrum of the lower section of seat 3 is locked at the upper end of swing seat 5.

Because underwater fairlead is placed in water for a long time, seawater corrosion and parts are avoided to get rusty, the material of the pulley spindle 2 It is not easy for 2Cr13,2Cr13 by seawater corrosion and corrosion, it is smooth ensures that pulley spindle 2 rotates, avoids pulley stuck.
