Description
Technical field
The present invention relates to a kind of bypass cable stringing method, also relates to dedicated auxiliary used in the operational method and set
It is standby, belong to power industry emergency first-aid repair or upkeep operation construction field.
Background technique
With the development of society, electric system plays increasingly in the national economic development and living standards of the people improve
Interruption adverse effect caused by national economy and people's lives of important role, power supply system are also more obvious, therefore protect
It is particularly significant to demonstrate,prove power network safety operation, power off time is greatly reduced, it is ensured that continuous, stable, safe power supply society needs
It asks, it is desirable that power construction department not only wants Efforts To Develop to bypass uninterrupted operation, but also to accelerate emergency first-aid repair and upkeep operation
Process；And do not have a power failure in repairing and upkeep operation carrying out, generally require to set up bypass cable, thus solve how
Stringing quickly is carried out to cable and the problems such as avoid the damage of cable, is to promote bypass uninterrupted operation to greatly develop to Guan Yin
Element.
During bypass operation, it usually needs build inicdental bypath power supply line by original conductive track, build
By-pass line length is much larger than 100 meters, and power cable should be at the same horizontal position, and crossing highway in the overlap joint of adjacent electric pole
When should meet distance to the ground and be no less than 6 meters, so remote, rise from electrification bypass operation require a kind of quick stringing method
And its ancillary equipment.
Domestic traditional bypass operation stringing mode is mainly using artificial and simple machine auxiliary, operational method master at present
It has the disadvantage that:
A, manual labor's intensity is big, working efficiency is low: the stringing of artificial traction and cable, paving in cable trough line process
If keeping its labor intensity larger, the artificial traction occurred during artificial traction is slipped, towing bracket overload breakage leads to it
When cable slides, will cause doing over again for labour more causes working efficiency low；
B, cable fault degree is big: its stringing cable is mostly that flexible cable tension degree itself is lower, and every section of cable is long
Degree up to 50 meters, when its stringing cable length be greater than 100 meters when, relatively long distance cable pulling and without cable support frame assist electricity
Cable also easily leads to cable fault, destruction or cable when supporting and mutually vertical phenomenon occurs for bearing rope, passes through between two adjacent cables heavier
Transition joint connection when, because transition joint is sagging cause both ends connecting cable due to pulling force caused by cable fault.
Summary of the invention
In order to overcome the above-mentioned deficiency of the prior art, the present invention provides a kind of bypass cable stringing method and its dedicated sets
It is standby, it can be realized the quick air line working of inicdental bypath line cord in electrified system, and avoid cable during stringing
Because draw it is improper, without cable support etc. caused by cable mutually hang down damage etc..
The technical solution used to solve the technical problems of the present invention is that:
A kind of bypass cable stringing special equipment, including cable around put collapse bracket, draught line ground supports device, import
Wheeled support device, pole mechanism connector, wires-erecting pulley and traction are twisted, and cable collapses bracket and traction and is twisted and two around putting
A draught line ground supports device, which is all individually positioned in, builds inicdental bypath line cord starting point and terminal point, on each electric pole
An importing wheeled support device is all installed by pole mechanism connector, the traction rope being twisted is drawn and passes through all importings wheel support
It is connected with across cable around the inicdental bypath line cord put after collapsing bracket after device；Two draught line ground supports devices one
End fixes on the ground, and the other end is connect by bearing rope with nearest importing wheeled support device, and adjacent two import wheel support dress
It is connected between setting also by bearing rope；The idler wheel of multiple wires-erecting pulley passes through draught line ground supports device and slides on bearing rope,
Wires-erecting pulley bottom is connect with inicdental bypath line cord.
A kind of bypass cable stringing method operates in accordance with the following steps:
A, stringing position and the stringing length for needing to build inicdental bypath line cord are determined；
B, support is collapsed around putting building inicdental bypath line cord start position and place multiple cable drums and a cable
Cable on each cable drum is passed through cable around gathering bracket is put jointly, is later consolidated its head with soft bandage by frame
It is fixed, form inicdental bypath line cord；
C, it will be connect between the consistent importing wheeled support device of electric pole quantity with bearing rope by operating personnel, every section of load
The length of rope is equal to the distance between two adjacent electric poles；
D, it is twisted building inicdental bypath line cord final position and place a traction, pulls out its traction rope and one by one
It passes through out of each importing wheeled support device, is finally connected with the soft bandage of inicdental bypath line cord to be drawn；
E, corresponding importing wheeled support device is fixed on to the height and position of electric pole corresponding requirements by pole mechanism connector；
F, both ends import the output end bearing rope draught line ground supports device phase with both ends respectively of wheeled support device
Connection, draught line ground supports device are fixedly connected with ground；
G, the idler wheel of multiple wires-erecting pulley is each passed through draught line ground supports device to slide on bearing rope, wires-erecting pulley
It is drawn after being connect with inicdental bypath line cord by the traction rope that traction is twisted bottom.
Compared with prior art, of the invention a kind of bypass cable stringing method and its special equipment, have the beneficial effect that
Following aspect:
A, the bypass cable stringing method used in the present invention is not necessarily to artificial traction cable, and auxiliary used in method
Equipment installation is fixed simple, reliable, avoids doing over again caused by work mistake, significantly reduces the labor intensity of operating personnel, mention
The security reliability in bypass operation is also increased while high working efficiency；
B, the importing wheeled support device and draught line ground supports device used in the present invention, can quickly fix bearing rope
Meanwhile and can with the support in relief cable distraction procedure, avoid longer cable traction when caused by cable mutually hang down, wear and
It destroys, there is stronger real dissemination.
