Description
Technical field
The present invention relates to cable laying technical field, be specifically related to a kind of outdoor complicated piping lane cable laying of bridge frame method.
Background technology
Along with Tong Ye company 2 × 104Nm3/h oxygen generating station and the construction of converter system, whole Tong Ye company on-site piping lane
Crane span structure begins to take shape.Complete from the outlet of 110KV transformer station to each 6KV electric substation YJV-6/6KV, 3 × 240mm2 high tension cable
Count 32 (without 1# oxygen generating station altitude chamber to 4, former smelting 4# electric substations) totally 32.7 kilometers, move towards path extremely complex: 1,
In 110KV transformer station, from high-voltage board outlet to vertical shaft.Vertical shaft has two passages, to 110 side high-voltage boards after entrance vertical shaft, interval
Under narrow and small and side walls and altitude chamber, cable trailing arm is triangle ironware, and various equipment cannot be put to good use.2, vertical shaft is to electrolysis plant
South, room enclosure wall, this section is the most straight, about 180 meters.3, in cell room, this section with front two sections the same, be all this and apply from now on
If the common sections of cable, and it is bilateral Multilayer bridge frame.Predominantly it is intended for a people side in a descending grade section, a uphill slope section and Factory Building
Two little curved segment compositions that body passes through.4, shaft part in north, including going the systems such as oxygen generating station, 350 fan stations and Improving Project electrolysis
The cable laying in direction, this time mainly lays 1# oxygen generating station and new power center (PC) Liang Ge electric substation cable.Share gantry part bag
Include three sections of flat segments, one section of descending branch and one period of abrupt slope ascent stage, one section two 90 degree turn round.The crane span structure of remainder is monolateral
Setting up, the crane span structure to new power center (PC) is two 90 degree and turns round and one section of straightway forms, and the crane span structure removing 1# oxygen generating station is then
Three sections of flat segments, falls one liter and three 90 degree are turned round, this segment length about 320 meters.5, electrolysis west section, including removing earth of positive pole comprehensive utilization
With workshop electric substation with electrolysis second phase electric substation cable, this section is straight, only one 90 degree turn round with one at descending grade, but both sides
Unshielded.6, east line crane span structure, this section is the longest, will transform new sulfate system cable, newly lay silver stove power center (PC) cable and pre-
Having stayed the position of Flash Smelting Furnace power center (PC) cable, seemed straight, but turned round at most, periphery protection is not in place, also has part height
Pressure, control, communication, monitor, crane span structure layer used with by the cable such as illumination.
In the face of path is moved towards in above-mentioned and complicated cable laying, use traditional cable laying method can not meet,
And the many employings of cable laying of bridge frame at present are manually laid, for complicated piping lane cable laying of bridge frame, owing to height laid by crane span structure

Detailed description of the invention
Below the present invention is described in further details.
Select the strand grinding machine of 5 tons of pull strengths, model JJM5-C, input power 4.4Kw, rated load weight 5T at a slow speed, quickly
2.5T, at a slow speed 4.5m/min, quick 8.5m/min；∮ 13 anti-twisting steel wire rope.Tractive auxiliary equipment mainly has end traction casing
∮ 80, middle traction casing ∮ 80, wire rope connector, traction cone.
A kind of outdoor complicated piping lane cable laying of bridge frame method, comprises the steps:
A, equipment are installed: one end being arranged on cabling circuit of pulling equipment arranges a strand grinding machine 2, cable reel stent 10
Arranging needs to do the cable of medial head according to cabling length more than or equal to 500m that cable reel stent 10 is placed on cable is total
The center of length；The terminal being then placed on cable laying circuit less than 500m, it is simple to the steel wire rope of folding and unfolding steel wire rope is received
Put frame 1 and be arranged on strand grinding machine 2 side, after the tractive by strand grinding machine 2, steel wire rope 3 is wrapped on steel wire rope retractable frame 1；
Intend the installation of release cable carriage, intend release cable carriage and include movable pulley 5, guiding fixed pulley, support wheel
4, lower pressure wheel 6, deflecting roller 7, movable pulley 5 is arranged on cable testing bridge walkway board with 2m uniformly for spacing, guides fixed pulley and sets
Putting above and below strand grinding machine 2, support wheel 4 and be arranged on the position that cable testing bridge declines, lower pressure wheel 6 is arranged on cable testing bridge
The position risen, deflecting roller 7 is arranged on the position that cable testing bridge turns to；
End bondage equipment includes end traction casing 9, middle traction casing, wire rope connector 8, traction cone, by traction
Cable is connected by cone with pull rope；
B: equipment install in place after, by steel wire rope 3 from strand grinding machine 2 end sequentially pass through guiding fixed pulley, movable pulley 5, lower pressure wheel 6,
Support the support above wheel 4 and deflecting roller 7, cable hank 11 and take turns to cable reel stent 10 end；By pull rope from the beginning of strand grinding machine 2 side
Reverse with manually moving at cable reel stent 10, traction cone is loaded in traction casing, further rises and strain gently after cable is entangled
Traction casing, is connected cable with pull rope by wire rope connector 8；
C, startup strand grinding machine 2, drawn cable to the crane span structure on strand grinding machine 2 top from cable hank 11 by pull rope, and cable is wanted
When entering switchgear house, remove end traction casing 9, and be replaced with middle traction casing, according to cable testing bridge to switchgear house power distribution cabinet
Distance, measure cable length, herein, centre traction casing is connected with cable, be again started up strand grinding machine 2, trailing cable, by
Artificial Control cable louding, slowly by cable pulling to power distribution cabinet position, completes cable pulling；
D, after cable tractive puts in place, start to be placed in the crane span structure of regulation cable from cable hank 11 end, until cable laying
Circuit terminal；
E, strand grinding machine 2, cable hank 11 point of release at be respectively configured a staff be responsible for twist grinding machine 2 start and stop communication
And cable pulling and cable hank 11 cable release work, it is respectively configured a work at each flex point, the turning of cable laying circuit
As personnel be responsible for the pull rope of both sides at flex point, deflecting roller, cable by work；Cable laying circuit crane span structure rising,
Drop point is respectively configured a staff and is responsible for each support wheel 4, the work of lower pressure wheel 6.
Strand grinding machine 2 is bolted on platform, and platform is welded by channel-section steel, angle steel；It is strictly on guard against tractive cable
Pulling force promotes strand mill, prevents the shake of strand mill from the power of letting out occur, makes cable laying circuit crane span structure to damage.
Step D reserves 1m-2m cable at the turning point, flex point of cable laying circuit；Convenient by turning point, flex point
Cable unloads from pulley.
Dispose angular movable pulley in the cable testing bridge trend place more than 15 °, reduce pull rope, cable on piping lane frame
Frictional force, prevents from scratching cable, reduces cable bad.
Step D by cable laying circuit tilts, vertical, the cable BV electric wire of climb and fall section carry out colligation；Make each curved
Good sag, camber is kept, it is to avoid cable is because expanding with heat and contract with cold phenomenon and unbalance stress causes damage at angle.
The cable manually dragged is the most also on sliding apparatus, facility, and the most both safety did not hinder cable joint-box, the most laborsaving；Also
There is the speed manually dragging cable basically identical with the speed of the strand main traction of mill, prevent cable accumulation, hair fastener from damaging cable.
