Abstract
The utility model provides a kind of damping device of Submarine Cable Laying, comprises drag reduction mechanism, and described drag reduction mechanism comprises upper cover, axle, back-up ring, bearing, pin, lower cover, upper cover wherein and lower cover structure completely the same, comprise curved body and shift fork.Upper cover and lower cover are fastened on cable by bolt, and cable installs drag reduction mechanism by certain spacing, and bearing is arranged on shift fork by axle, and by two back-up rings location, finger setting is passed through in the axial activity of axle.The utility model adopts the mode of bearing element, with rolling friction replacement activity friction, greatly reduces resistance, and the external protection of protection cable is injury-free, has and installs simple, cabling feature easily.
Description
Technical field
The utility model relates to a kind of damping device of Submarine Cable Laying, is specially the device of a kind of specialty for the minimizing resistance of Submarine Cable Laying, belongs to mechanical movement means.
Background technology
At present; domestic when laying submarine cable; normally used method is with the laying method of oil as lubricant; lubricating oil is poured into exactly in cable tube; with the poling machine handling cable of specialty in cable tube; the effect of lubricant is exactly the frictional force reducing cable and cable tube inwall, and the external protection of protection cable is injury-free as far as possible simultaneously.When the distance of cable laying is longer, as during more than one kilometer, perfusion lubricating oil cost is comparatively large, and the viscosity of lubricating oil is comparatively large simultaneously, and the resistance of generation is just very large, brings larger difficulty to cabling.
Utility model content
For the weak point existed in the problems referred to above, the utility model provides the device of a kind of specialty for the minimizing resistance of Submarine Cable Laying.
For achieving the above object, the utility model provides a kind of damping device of Submarine Cable Laying, comprises drag reduction mechanism; Described drag reduction mechanism is by certain spacing installing cables.
Upper cover and the lower cover of described drag reduction mechanism are bolted on cable;
Described upper cover is consistent with the structure of described lower cover, comprises curved body and shift fork, and described shift fork is positioned at the outside of described curved body, and is directly connected;
Aperture a is opened on the top of described shift fork, bearing is arranged on the centre of described shift fork by axle, a back-up ring is respectively installed on the both sides of described bearing, one end of described axle is that staged has large end, the other end of described axle there is aperture b mount pin, make the structure of whole drag reduction mechanism closely, quick for installation.
Preferably, the spacing that described drag reduction mechanism installs on the cables. is 1-2m, is preferably 1m.
Preferably, on described, cover the secondary shift fork of installation 3, under described, cover the secondary shift fork of installation 3, and symmetrical.
Preferably, described upper cover and described lower cover close up after cross section diameter of a circle be less than the diameter of described cable.
Preferably, described pin is expansion pin.
The operation principle of the damping device of described Submarine Cable Laying is as follows:
When the poling machine handling cable of specialty is inner to cable tube; due to the own wt of cable; cable is made down to encounter the inwall of cable tube; when using drag reduction mechanism; the inwall of cable tube encountered by the bearing of drag reduction mechanism; during cable movement; has the inwall generation rolling friction of a bearing and cable tube at least; so just greatly reduce resistance during cable movement; drag reduction mechanism is arranged on cable by certain spacing simultaneously; effectively can prevent the activity friction of cable and cable tube inwall, ensure the intact of cable external protection.
Compared with prior art, the utility model has the following advantages:
1, the utility model adopts the mode of bearing element, with rolling friction replacement activity friction, greatly reduces resistance, and the external protection of protection cable is injury-free;
2, drag reduction mechanism is reasonable in design, with low cost, easy for installation, adopts latch structure location effectively can prevent loosening of axle.
3, the utility model adopts the mode of bearing element, without the need to charging-up lubricant oil in cable tube, cost-saving, preventing pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view at A-A place in Fig. 1;
Fig. 3 is the enlarged drawing at B place in Fig. 2.
Main element symbol description is as follows:
1-cable, 2-upper cover, 3-axle, 4-back-up ring, 5-bearing, 6-sells, 7-lower cover, 8-cable tube, 31-curved body, 32-shift fork.
Embodiment
As shown in Figure 1-Figure 3, a kind of damping device of Submarine Cable Laying, comprises drag reduction mechanism;
Drag reduction mechanism presses on the spacing installing cables 1 of 1-2m.
Upper cover 2 and the lower cover 7 of described drag reduction mechanism are bolted on cable 1;
Described upper cover 2 is consistent with the structure of described lower cover 7, comprises curved body 31 and shift fork 32, and described shift fork 32 is positioned at the outside of described curved body 31, and is directly connected; Described upper cover 2 installs 3 secondary shift forks 32, described lower cover 7 installs 3 secondary shift forks 32, and symmetrical.
Aperture a is opened on the top of described shift fork 32, bearing 5 is arranged on the centre of shift fork 32 by axle 3, a back-up ring 4 is respectively installed on the both sides of described bearing 5, one end of described axle 3 is that staged has large end, the other end of described axle 3 there is aperture b expansion pin 6 is installed, make the structure of whole drag reduction mechanism closely, quick for installation.
Cross section diameter of a circle after described upper cover 2 and described lower cover 7 close up is slightly less than the diameter of described cable 1.
The course of work of the present utility model is; when the poling machine handling cable 1 of specialty is inner to cable tube 8; due to cable 1 installing drag reduction mechanism by certain spacing; cable 1 is in motion process; due to self weight down; the bearing 5 of drag reduction mechanism have at least one with the inwall generation rolling friction of cable tube 8, reach the object reducing resistance, simultaneously the external protection of available protecting cable 1.
Only as described above, be only preferred embodiment of the present utility model, such as professional who are familiar with this art. and after understanding technological means of the present utility model, natural energy, according to actual needs, is changed under instruction of the present utility model.Therefore all equal changes of doing according to the utility model claim and modification, once still should belong to the scope that the utility model patent contains.
