In drag chain work preassembly in factory flexible pipe, if desired for safeguarding or changing during subsequent production, operate and its difficult, the duration affects
Greatly, cost is high.
Utility model content
For solving above-mentioned technical problem, the utility model provides a kind of sea work drilling platforms towing chain device, achievable drag chain
Interior dismounting large-caliber hose and cable, need not pre-install flexible pipe, convenient disassembly, are easy to safeguard, change flexible pipe and cable.
The utility model employs the following technical solutions：A kind of sea work drilling platforms towing chain device, including drag chain body, described
Drag chain is originally provided with cable installing zone and flexible pipe installing zone in vivo, and described drag chain is originally provided with removable vertical separation round bar in vivo and incites somebody to action
The intrinsic space of drag chain is divided into multiple difference in functionality cable installing zones and different bore hose installing zone, described removable perpendicular
Include two vertical round bars, two support channel-section steels and two L-shaped stop baffle plates to separating round bar, two support channel-section steel bottoms to be all provided with
There is through hole, described two vertical round bars are located between two support channel-section steels and its upper and lower ends both passes through and supports the logical of channel-section steel bottom
Hole, described two L-shaped stop baffle plates are located at two respectively and support in channel-section steels, and wherein, the bolt that passes through of L-shaped stop baffle plate is consolidated
On the side of channel-section steel, another side is located at the upper and lower ends supporting channel-section steel bottom and blocking two vertical round bars.
Described cable installing zone adopts the less cable of bending radius, and the hose coupling of described flexible pipe installing zone is pacified for clip
The HUB form of dress or the joint of threaded removable form.
The utility model has the advantages that：1st, towing chain device is designed to partly removable, but ensures not affecting drag chain simultaneously
Integrated carrying ability, will not fall apart.2nd, flexible pipe need not be pre-installed, large-caliber hose can also be pacified at the scene in the platform construction stage
Dress.3rd, it is also possible to convenient pass through only to dismantle drag chain interior part non-bearing bar during platform operation at sea, safeguard and change flexible pipe
And cable, it is greatly saved the time, provide guarantee for higher production efficiency.4. solve original installation difficulty and maintenance
Difficult puzzlement.

Specific embodiment
In order to deepen, to understanding of the present utility model, to make into one to of the present utility model below in conjunction with embodiment and accompanying drawing
Step describes in detail, does not constitute the restriction to protection domain of the present utility model.
As shown in figure 1, the effect of towing chain device is mainly rig floor and cantilever beam with respect to main deck on extra large work drilling platforms
11 mobile when, towing chain device passes through to slide on drag chain slide rail 12, drives and is contained in its internal flexible pipe 8 and moves together with cable 10
And protect them, ensure water on rig floor and cantilever beam, electricity, oil, the continuous effective supply of mud etc..
The utility model changes drag chain structure first, and the vertical round bar that separates is designed to removable mode, simultaneously because perpendicular
It is not primary load bearing structure to round bar, during dismounting, whole drag chain structure does not fall apart.After vertical round bar is removed, flexible pipe is fitted inside,
Hose coupling 9 makes the HUB form of clip installation or threaded removable form into by non-disconnectable welding point simultaneously, so
The clear space that flexible pipe is fit into drag chain requires to substantially reduce, and only be can achieve with less grating space.Cable installing zone is to the greatest extent
Amount adopts the less cable of bending radius 10, makes to draw cable more smooth.
Concrete structure is as follows：As Figure 2-Figure 5, a kind of sea work drilling platforms towing chain device, including drag chain body 1, drags
It is provided with cable installing zone 5 and flexible pipe installing zone 6 in chain body 1, be provided with removable vertical separation round bar in drag chain body 1 and will drag
The intrinsic space of chain is divided into multiple difference in functionality cable installing zones and different bore hose installing zone, removable vertical separation
Round bar includes two vertical 2, two support channel-section steels 3 of round bar and two L-shaped stop baffle plates 4, and two support channel-section steel 3 bottoms to be equipped with
Through hole, vertical round bar 2 be located at two support channel-section steels 3 between and its upper and lower ends both pass through support channel-section steel 3 bottom through hole, two
L-shaped stop baffle plate 4 respectively be located at two support channel-section steels 3 in, wherein, L-shaped stop baffle plate support is fixed on by bolt 7
On the side of channel-section steel 3, another side is located at the upper and lower ends supporting channel-section steel 3 bottom and blocking two vertical round bars 2.
When using, turn on bolt and nut first, take the L-shaped stop baffle plate at vertical round bar two ends apart, then pull out vertical
Round bar, which increases the space of grid areas（As shown in Figure 6）, dismantle after vertical round bar, installing space is three-in-one, be easy to
Flexible pipe and cable are installed.Then by flexible pipe（After HUB head or removable joint of dismantling）Pass through from grid, give necessary simultaneously
Chain block auxiliary is installed, and cable needs to install after flexible pipe installs again, because part flexible pipe is heavy caliber, to erection clearance
Between require higher, cable installing space demand is less, can after install.After installing by shown position successively, you can reinstall perpendicular
To round bar and L-shaped stop baffle plate.
As during operation at sea, needed to safeguard and remove flexible pipe and cable, same unclamps stop baffle plate, takes out and vertically justifies
Bar, is then assisted with chain block and takes out flexible pipe and cable.
