Abstract

The utility model relates to a plastic live crossover frame, which discloses construction equipment for an electric transmission and transformation line. A crossover ladder 1 is formed by that insulation plastic pipes are mutually connected into a square pipe net shape through four joints, three joints and two joints. The crossover ladder 1 is perpendicular to the ground; a fastening rope 2 is fixed on the ground and is connected with the crossover ladder 1 to prevent the crossover ladder 1 tilting. The crossover ladder 1 is cramped by a waist hoop 4; the height of the crossover ladder 1 is higher than that of the original electric wire 10, and the top end is connected with an overline roller 5. Two symmetrical crossover ladders 1 are connected by a waistline 6. The utility model has the advantages of simple structure, convenient assembly and disassembly, and can work with electricity.

Description

The charged crossing frame of plastics

The utility model relates to the power transmission and transformation line construction equipment, particularly the crossing frame of power transmission and transformation line charging construction.

Usually in the work progress of defeated modified line road, usually need mutual scissors crossing, need build this tower that highly is higher than crossed line in the crossover point both sides usually, and need stop to be crossed over operation by the operation on cross-line road.The 90 of Ministry of Water Resources and Electric Power of People's Republic of China (PRC) electrical safe working order.Regulation: can make safe and reliable crossing condition, will be foreshortened to crossing frame by cross-line road interruption duration and bind, the stage of tearing the top open and implementing the lead leap.No matter build wood pagoda or tower is built crossing frame, it is set up support body itself and expends bigger, particularly under complicated landform, landforms situation, it removes also difficulty, simultaneously, and when crossing over operation, must stop by the work on cross-line road, can cross over construction, can cause power supply, electricity consumption both sides' loss like this, cause the bigger wasting of resources.

Chinese patent CN1043229A discloses a kind of composite crossover device of alive circuit, this device is had the bridge post of cross through hole by two ends, be used for the bridge post is fixed on jig on iron tower in the crossed line or the line bar, the guiding principle rope, the order net, the order net is held ring, order net end socket guiding principle rope sleeve, spherical skating and other corresponding rope are formed, the bridge post is by on the iron iron tower or line bar that are separately fixed at this retaining of circuit crossover point two ends on the corresponding card, and make its distance that exceeds crossed line reach safe distance, the order net is divided into two, be connected with a plurality of order net links of making by insulating material at a wherein end of every, being connected with two order Netcoms of wooden underseal at its other end crosses the order net of its end and hangs not that the position relatively penetrates the guiding principle rope, between the order net link of missing, be with the guiding principle rope sleeve, on the guiding principle rope on order net both sides, be with the order net end socket of making by insulating material.And be connected with rope thereon and link to each other with ground, the through hole of two bridge column end is passed at the guiding principle rope two ends that penetrate behind the order net respectively, after the tension of guiding principle rope, its two ends are provided with stay cord, spherical foxy spheroid for being made up of two hollow hemisphere with order net bottom envelope on the net mutually with fixing centre, ground order respectively, contact-making surface place in two hollow hemisphere has through hole, between the two hemispheres by screw.

This apparatus structure is comparatively complicated, and crosses over requirement and carry out on former brandreth, and the scope of application is narrower.

It is a kind of simple in structure that the purpose of this utility model provides, and assembling and disassembling is convenient, and the charged crossing frame of plastics of energy live line working.

The charged crossing frame of the utility model plastics is made up of leap ladder, waist hoop, waistline, fastening rope and the mistake line cylinder of two symmetries, and crossing over ladder is that the ambroin pipeline passes through four roads, three roads and twice joint, and it is netted to be interconnected to rectangular tube.Leap is terraced perpendicular to ground, and fastening rope is fixed on ground and prevents to cross over the ladder inclination with crossing over terraced linking to each other, and the leap ladder will be higher than the height of the electric wire of striding with waist hoop banding, leap ladder, and connects the line cylinder on the top, between the leap ladder of two symmetries, connects with waistline.Crossing the line cylinder is made up of two anchor ear cards, two bearings, metal guide, central shafts, the anchor ear card is embraced on the spreader of crossing over terraced top, is fixed fixed center axis on the anchor ear card by nut, nut, fix two bearings on the central shaft, bearing outside has the metal guide.

The utility model plastics live across ladder, waist hoop, fastening rope all are that insulating plastics material is made, and make the insulation of charged crossing frame of whole plastics and ground, make the construction can live line working.And crossing over ladder is that short plastic pipe is formed by connecting by four roads, three roads, twice joint, and assembling and disassembling is convenient.

Fig. 1 the utility model structure front view 2 the utility model structure side view Fig. 3 the utility model structure vertical view Fig. 4 the utility model are crossed line cylinder schematic diagram, and the utility model is described in further detail below in conjunction with drawings and Examples; 1 is to cross over ladder, the 2nd among the figure, fastening rope, the 4th, waist hoop, the 5th, line cylinder, the 6th, waistline, the 7th, anchor ear card, the 8th, bearing, 9 metal guides, the 10th, central shaft, 11 former iron towers, 12 new crossover tracks, 13 horizontal stretch lines, 14, origin wire.

The charged crossing frame of the utility model plastics is made up of leap ladder 1, waist hoop 4, waistline 6, fastening rope 2 and the mistake line cylinder 5 of two symmetries, and crossing over ladder 1 is that the ambroin pipeline passes through four roads, three roads and twice joint, and it is netted to be interconnected to rectangular tube.Cross over ladder 1 perpendicular to ground, fastening rope 2 is fixed on ground and crosses over ladder 1 and link to each other and prevent to cross over ladder 1 and tilt, and crosses over terraced with waist hoop 4 bandings, cross over the height that ladder 1 will be higher than origin wire 14, and connected on the top between the leap ladder 1 of 5, two symmetries of line cylinder, connect with waistline 6.Crossing line cylinder 5 is made up of two anchor ear cards 7, two bearings 8, metal guide 9,

central shafts

10,7 armfuls on anchor ear card is fixed by nut, nut on the spreader of crossing over terraced 1 top, and fixed center axis 10 on the anchor ear card, fix two bearings 8 on the central shaft 10, the bearing 8 outer metal guides 9 that are with.The ambroin pipe is sawn into segment, connect into the pipe network shape by four roads, three road twice, cross over terraced 1 14, two of the origin wires that will be higher than on the former iron tower 11 and cross over available horizontal draw line 13 connections between the ladder 1, keep crossing over ladder 1 perpendicular to horizontal line, new crossover track 12 is to cross operation on the line cylinder 5.
