Fall including being fixed on crossing frame on wire is slided, and connection insulating cord at the top of side frame, insulating cord hangs down after being slided through fall.
Chassis and side frame of the present invention are rotatable insulation tubular structure, can carry ground wire, are changing ground
During line, because of the particularity of chassis and side cage structure, the dragging of ground wire is more laborsaving, it is possible to increase operating efficiency, and its
It disclosure satisfy that insulating requirements, it is safe and reliable in Renewal process.
Further, the pulley for including about two fixations is slided in the fall, and upper sheave is used to crossing frame being fixed on
On wire, lower pulley passes through for insulating cord.
Preferably, the structure of chassis and side frame is：Rotation pipe including central shaft, outside central shaft, rotate pipe and pass through
Bearing is fixed on center shaft, and the both ends of central shaft are hinged with one end of side frames central shaft fix respectively in chassis.In bearing
In the presence of, rotating pipe can be around central axis, and then the dragging saved when changing ground wire is exerted oneself.
Further, the length parameter on chassis and side frame is：The length of chassis and side frame ratio is 2-4：1.Preferably,
Length over end sills is 2.2-2.5 rice, and side frame length is 1.0 meters, and it is 150mm to rotate pipe external diameter, internal diameter 100mm, bearing at interval of
0.5m sets one.
Preferably, a diameter of 22mm of insulating cord.
Further, to increase connection reliability of the crossing frame in power transmission line, fall is slid onto provided with two hooks, two extensions
Hook is provided with anti-dropout safety fastener in 90 degree of settings, hook.
Further, pipe is rotated due to carrying ground wire, it is therefore desirable to higher insulating properties, it is strong using machinery to rotate pipe
The higher isolation material of degree is made, and one layer of wear-resisting coatings of outer re-coating is managed rotating, to increase security.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention can substitute the crossing frame set up or crane etc., reduce the labor intensity of operating personnel, improve work
Make efficiency, reduce security risk, ensure that the person and equipment safety in operation process；The use of the present invention is not by landform bar
The limitation of part, it is applied widely；Further, since without setting up crossing frame again, reduce expense.

Embodiment
The present invention is further explained with reference to the accompanying drawings and examples.
Embodiment 1
A kind of ground wire changes special crossing frame, as shown in figure 1, the side frame 2 including chassis 1 and positioned at the both ends of chassis 1, side frame
2 tilt the both ends for being articulated with chassis 1, and the top of side frame 2 is provided with insulating cord 5, and the crossing frame also includes fall and slides 3, and 3 bags are slided in fall
Pulley 4 fixed up and down and hook are included, upper sheave 4 is used to for crossing frame to be fixed on adjacent wire, lower pulley 4
Passed through for insulating cord 5, the insulating cord 5 hangs down after passing through pulley 4, and pulley 4 is recessed provided with being moved for wire and insulating cord 5
Groove, the hook is located at fall and slides 3 top settings two, and slides 3 tops in fall and fixed in an angle of 90 degrees, and hook is provided with anticreep
Fall safety fastener.
Chassis 1 and side frame 2 are rotatable insulation tubular structure；Include central shaft 6, turn outside central shaft 6
Dynamic pipe 7, rotate pipe 7 and be fixed on by bearing 8 on central shaft 6, the both ends of central shaft 6 center with side frames 2 respectively in chassis 1
One end of axle 6 is hinged.In the presence of bearing 8, rotating pipe 7 can rotate around central shaft 6, and then save dragging when changing ground wire
Drag firmly.
Parameter on crossing frame：The length of chassis 1 is 2.2 meters, and the length of side frame 2 is 1.0 meters, is turned in chassis 1 and side frame 2
The dynamic external diameter of pipe 7 is 150mm, and internal diameter 100mm, bearing 8 is at interval of 0.5m settings one.5 a diameter of 22mm of insulating cord, length are
1m, what the length of certain insulating cord 5 can also continue according to being actually needed or directly change other length has insulating capacity
Rope.
Pipe 7 is rotated due to carrying ground wire, it is therefore desirable to higher insulating properties, it is higher using mechanical strength to rotate pipe 7
Isolation material be made, rotate pipe 7 outside be coated with one layer of wear-resisting coatings, to increase security, can use following
Coatings are made in the component of parts by weight：50 parts of epoxy resin, 20 parts of acrylic resin, 10 parts of organic siliconresin, cermet
5 parts of part, 3 parts of aluminium hydroxide, 10 parts of acrylic acid, 2 parts of distilled water.
When in use, the upper sheave 4 fall slided in 3 is fixed on the adjacent wire of ground wire, is linked up with solid for aiding in
It is fixed, then chassis 1 and side frame 2 are lifted below ground wire by insulating cord 5, it would be desirable to which the new ground wire of replacing is mounted in chassis
On 1, the ground wire for needing to change can just be removed in the air from height by the rotation for rotating pipe 7, new ground wire is installed and fixed, it is time saving
It is laborsaving, can solve the problem that previously during ground wire is changed carry crossing frame or using wasted time and energy existing for crane, expense
The problem of higher, and risk is high, especially crane, once occur to touch by mistake, easily get an electric shock, and carry cross on the ground
Frame or using crane, can hinder traffic above-ground, which reduce the labor intensity of operating personnel, reduce and set up crossing frame process
In security risk, change crane can not full landform use the drawbacks of, ensure that being smoothed out for ground wire replacement operation, reduce
Operating expenses, not only ensure that the person and equipment safety in operation process, and improve operating efficiency, reduce expense
With.
