Abstract
A 220kv conductor riser belongs to the technical field for design and manufacture of conductor risers used for repairing high-voltage power transmission lines and consists of a main post and a hoisting screw rod, wherein the upper end and the lower end of the main post are respectively provided with a duplex plate; the upper duplex plate is provided with a conductor rising hook; and a single connection plate is provided with the hoisting screw rod; and the main post is provided with a pedal plate. In use, the conductor riser is fixed between a conductor and a post tower; and an operating staff can walk to and fro between the post tower and the conductor through the pedal plate on the main post, just like walking on a ladder made of solid material. In case of conducting the operation of raising conductors, the operating staff can rotate a handle on the hoisting screw rod so that the screw rod drives the conductor rising hook to slowly rise and lift up the conductor from the original position, and subsequently, the operating staff can implement the installation or repair operation. As the main post is made of steel pipes, the conductor riser is very stable after fixed. Therefore, the staff can conveniently walk on the conductor riser, with the problems of unstable standing and likely danger due to a swaying flexible ladder being solved. In addition, as the hoisting screw rod is equipped, the troubles of carrying and installing a hoist crane can be omitted. The conductor riser is convenient and fast for use and greatly improves operating efficiency.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of ultra-high-tension power transmission line maintenance with line lifter.
Background technology
In the replacing of the installation or the maintenance, particularly composite insulator of facility, all be to adopt the method that hoist crane is installed on the existing ultra-high-tension power transmission line, lead is mentioned, and the weight of hoist crane own be very big, carry and install all very trouble.Physical demands to the workmen is very big.In addition,, can not trample because the composite insulator quality is softer, thus operating personnel rope ladder must be fixed between shaft tower cross-arm and the lead so that come and go operation.Because rope ladder is difficult for fixing, very easily rock, operating personnel are not steady on one's legs at all, consume one's strength greatly.Working together, promptly effort is dangerous again.Finish once-through operation and must expend the plenty of time.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of lead lifter very easily that carries, installs and use all, to solve the problem that exists on the existing operational method.
Structure of the present utility model is as shown in drawings: be made of mobile jib and lifting spindle.Respectively there is a pair of yoke plate at two ends up and down at mobile jib.The duplex plate is by being bolted on the mobile jib.Mobile jib is high strength steel control.On the duplex plate of top a thread-lifting hook is arranged.Have a simply connected plate on the duplex plate of bottom.Following duplex plate and simply connected plate pass through bolt.On the simply connected plate, have lifting spindle.Have pedal on the mobile jib.Use of the present utility model is to be fixed between lead and the shaft tower, and operating personnel can travel to and fro between between shaft tower and the lead by the pedal on the mobile jib, as the ladder of hard material making.As carry line when operation, the handle on the rotatable lifting spindle makes leading screw drive thread-lifting hook and slowly rises, and lead is mentioned leave original position, just practicable installation of operating personnel or maintenance operation.Because mobile jib of the present utility model is steel pipe system, be fixed between shaft tower and the lead very stablely, the staff can walk in the above easily, has solved the astasia that rocking of rope ladder brought, the problem of easily causing danger.In addition, owing to have lifting spindle, can remove the trouble of carrying, installing hoist crane from.It is quick to be easy to use, and improves operating efficiency greatly.
Description of drawings
