The utility model is characterized in that the conicity of the telegraph pole body changes gradually from bottom to top, the conicity of the telegraph pole body positioned below is larger than the conicity of the telegraph pole body positioned above and the cross arm is composed of a long and a short cross arms. The utility model has the advantages that the telegraph pole with changeable conicity can effectively increase the flexing resistance of poles and towers, and the cost is low.
Description
Technical field
The utility model relates to power transmission facility, specifically a kind of partial prestressing taper mutation concrete electric pole.
Background technology
90 ° of angle towers of 10KV transmission line of electricity are a kind of the most common and need the shaft tower that often uses, owing to be subjected to the influence of lead biaxial tension, the tension moment of flexure of shaft tower are required very big, and the stiffness of shaft tower is very high.Do not have above two kinds of technical condition to do assurance, shaft tower is easy to crooked until collapsing.Owing to be erected at thickly populated city and market town, its safety receives very big concern.Electric power installation portion door knob is during to the circuit corner, and general the employing erect the ordinary concrete bar and played backguy and solve, and adopted novel steel tube tower and iron tower in recent years.But the former beats the backguy shaft tower security incidents such as bar takes place easily after backguy is stolen, and backguy at megalopolis the electric leakage and the accident that hacks takes place easily.Latter's cost is high, and foundation excavation is time-consuming expensive, and the city also has influence on traffic and city look and feel.
Summary of the invention
The purpose of this utility model is to design a kind of partial prestressing taper mutation concrete electric pole, and the body of rod of this taper mutation can effectively improve the stiffness of shaft tower, and cost is lower.
According to the scheme that the utility model provides, on the top of the body of rod cross-arm is installed, cat ladder is installed on the body of rod, it is characterized in that: the tapering of the body of rod gradually changes from the bottom up, and is positioned at following body of rod tapering greater than the body of rod tapering that is positioned at above it.
Cross-arm is made up of long cross-arm and hyphen load.In cross-arm, an end of cross bar is fixedlyed connected with semicircle anchor ear, and anchor ear is threaded with other semicircle anchor ear utilization.Connecting portion at anchor ear and cross bar is welded to connect piece, and thread gripping-board is installed on cross bar.The other end at cross bar connects end plate.At the edge of semicircle anchor ear outward extending flank is set, installing hole is set on flank, between flank and anchor ear, boss is set.
In cat ladder, the cat ladder bar is installed on the body of rod, at the cat ladder bar pedal parallel with the cat ladder bar is installed equably.
High-intensity taper mutation partial prestressing concrete electric pole with compare with equal bending moments common electrical bar, can save steel 15～20%, improve intensity 20～30%, stiffness improves 20～30%.Aspect economic benefit, become awl electric pole and steel pipe pole and iron tower in equal tension moment of flexure, under the same service condition, cost and selling price are 1/3 of steel pipe poles, 1/2 of iron tower, and the high-grade concrete electric pole can accomplish 20 years non-maintaining, save anticorrosion expense and antirust disposal cost 50%.

The specific embodiment
As shown in the figure: cross-arm is installed on the top at the body of rod 3, on the body of rod 3, cat ladder is installed, the tapering of the body of rod 3 gradually changes from the bottom up, and be positioned at following body of rod tapering greater than the body of rod tapering that is positioned at above it, flange is arranged at the bottom at the body of rod 3, boss 2 is arranged between the body of rod 3 and flange, and during installation, flange is connected with ground 1.Cross-arm is made up of long cross-arm 5,6 and hyphen load 7,8, and in cross-arm, an end of cross bar is fixedlyed connected with semicircle anchor ear 9, and anchor ear 9 is threaded with other semicircle anchor ear utilization.Cross bar constitutes box structure by two blocks of side plates 16 that are positioned at top top panel 15, are positioned at following base plate 17 and are positioned at both sides, to improve the intensity of cross-arm.Connecting portion at anchor ear 9 and cross bar is welded to connect piece 12, and thread gripping-board 13 is installed on cross bar.The other end at cross bar connects end plate 14.In cat ladder, cat ladder bar 4 is installed on the body of rod 3, at cat ladder bar 4 pedal 10 parallel with cat ladder bar 4 is installed equably.At the edge of semicircle anchor ear 9 outward extending flank 18 is set, on flank 18, installing hole is set, between flank 18 and anchor ear 9, boss 11 is set.Cross-arm is with the cross-shaped top that is installed on the body of rod 3, and contiguous block and boss all play booster action, and two semicircular anchor ears wrap in outside the circular body of rod, with bolt two semicircular anchor ears are fixedly connected on the body of rod again.
In use, cat ladder is installed on the body of rod, pedal is horizontal, on the top of the body of rod 3 with the cross-shaped top that is installed on the body of rod 3, on the body of rod 3, thread gripping-board is installed, and two parallel thread gripping-boards are installed on long cross-arm, on the hyphen load, 1 thread gripping-board are installed, again with erecting cable on the thread gripping-board of cross bar.When needs maintenance and maintenance cable, operating personnel can climb up along cat ladder.
Main outward appearance and technical data: 1, become awl electric pole footpath 500mm slightly, root footpath 700mm.Tapering 1/65, length are 13m.The partial prestressing manufacturing process.2, become awl electric pole footpath 500mm slightly, root footpath 736mm.Tapering 1/55, length are 13m.The partial prestressing manufacturing process.More than two kinds become all flanged dishes of awl electric pole root, be convenient to construction and install.3, design tension moment of flexure 1080KN.m allows to use moment of flexure 600KN.m, adapts to the stringing needs of city and 90 ° of corner pole double loops of market town 10KV LGJ-240 lead and JKYLGJ-240 insulated conductor.
