Abstract
The utility model relates to a rolling device for erecting power transmission line, comprising a horizontal bar, oblique bars respectively inclinedly mounted on the two ends of the horizontal bar by connecting pieces, and suspension rings mounted on the free ends of the oblique rods and rotable along the radial direction, wherein the horizontal bar and oblique bar respectively include an inner bar and a rolling sleeve mounted on the outer surface thereof. The rolling device can make a trailed power transmission line roll on the rolling device, and save tractive force since the rolling friction resistance is far smaller than the sliding friction resistance.
Description
Technical field
The utility model relates to a kind of tourelle of the usefulness that erects power transmission lines.
Background technology
Because the transmission pressure particularly quality of high voltage electricity transmission conductive wire itself is just bigger, and adjacent two iron towers that are used to support transmission pressure have bigger span, the barrier that simultaneously between adjacent two iron towers, exists quilts such as electrified body, crops, trees, river, road, building and structures to cross over, so, set up or dismantle transmission pressure and be a complexity and difficult engineering.
In the prior art, setting up or dismantle transmission pressure usually adopts and is installed in the guiding rope between adjacent two iron towers and is suspended on that the guiding rope is gone up and by the coaster of backguy control, and for avoid transmission pressure and ground or with above-mentioned by contacted crossing frame of across obstacle and insulation net, the logical frame structure of making by the aluminium alloy of steel alloy or lighter weight of crossing frame wherein.Because the transmission pressure that need set up or be removed is under the traction of coaster, to between adjacent two iron towers, move, and in the process that transmission pressure moves, be to support and slippage thereon by crossing frame, this shows, crossing frame is not only being carried the weight of transmission pressure, also and between the transmission pressure produce sliding friction simultaneously, so, crossing frame is firm in any case also easily by the bigger frictional force wearing and tearing that transmission pressure produced of slippage, the old transmission pressure that particularly is removed, because of its surface is similar to the zigzag tip, easier making apart from frame more damaged; In addition; frictional resistance between transmission pressure and the crossing frame also can produce considerable influence to traction element; because of guiding rope and coaster; and backguy is subjected to the effect of wind-force in the air at height; guiding rope and phenomenons such as backguy winding and coaster skew appear through regular meeting; the back coaster takes place and moves difficulty in this phenomenon; and the frictional resistance that guiding rope and backguy winding and coaster also need to overcome under shift state between transmission pressure and the crossing frame could move transmission pressure; be easy to cause phenomenons such as transmission pressure stagnation; and then influencing operations such as construction progress and increase maintenance capacity, its construction cost obviously improves.
Summary of the invention
The purpose of this utility model provides the tourelle that a kind of mode of utilizing rolling friction solves the usefulness that erects power transmission lines of problems such as the big and crossing frame of tractive effort is fragile.
The tourelle of the usefulness that erects power transmission lines that the utility model proposed comprises transverse bar member and is mounted obliquely within the inclined member at transverse bar member two ends respectively by connector, and be installed in that each root inclined member is free-ended can be along the suspension ring that radially rotate, in described transverse bar member and inclined member include rod member and be installed in the rolling sleeve pipe of rod member outer surface.
Described transverse bar member and two ends be separately installed with bearing, the rolling sleeve pipe is fixed on the outer surface of bearing.Described inclined member is provided with two, and the link of two inclined members connects by knuckle, and at the knuckle position spring and the resilient sleeve that is installed in the spring outer surface is installed.Angle between described transverse bar member and the inclined member is between the 100-140 degree.
The tourelle of the usefulness that erects power transmission lines that the utility model proposed can make trailed transmission pressure roll thereon, because rolling frictional resistance little sliding-frictional resistance far away, so, use this kind device can save tractive effort; Simultaneously, owing to be to roll to contact between transmission pressure and this device, even if it is there is the zigzag tip on the transmission pressure surface, also difficult with this device scuffing; In addition, resilient sleeve is all adopted in transverse bar member and the connection between the inclined member in this device, and this is installed can not influence the cover that rolls after the random bending yet and roll, so, when using this device,, extraneous wind-force and other power can not impact it even if being applied on this device yet.
