Description
Technical field
The invention belongs to Maintenance of Electric Transmission Line technical field, and in particular to a kind of operation of long-span electric transmission line maintenance
Car.
Background technology
Great span category tall and slender structure of the height more than 100 meters, in power transmission sequence Great span be primarily subjected to wind load,
Earthquake load and installation load, wherein especially using Wind effects as Sheng.Rivers and lakes river seashore edge at the general position of Great span, wind environment are disliked
It is bad, thus the dynamic response in the case where wind lotus acts on is particularly strong, therefore Great span often adds the group of stockbridge damper using dump wire clamp
Close precautions against earthquakes.Due to the importance and particularity of Great span, eliminate Great span defect and often require that high standard, high efficiency.So
And because Great span is towering, work high above the ground especially ground wire, optical cable operation, to operating personnel's psychological bearing capability and labor intensity
Etc. being proposed high requirement, certain difficulty is caused for defect elimination work.
For ground line defect, the common driving outlet defect elimination mode of generally use.Common driving is by front and rear two pulley and support
Frame forms.Operating personnel side is sat or ridden on support frame, and outlet is realized by front and rear two pulley.But common driving does not possess more
Barrier ability.For Great span tower, defect elimination uses pin hook outlet method at present, during operation, will go out stitch and is hooked on ground wire, optical cable
On, caprone cable is respectively fastened on the pin ring of bipod hook and makees balance rope, restrict along tower top frame aisle backward at about 20 meters with people
Member's manipulation, to keep outlet personnel to be in stand up position all the time in outlet operation process, prevents from losing center of gravity.Outlet personnel stand
To going out on stitch hook, a waist rope is beaten on optical cable (among two hooks), first carries lateral crus, pin hook moves forward 0.4~0.6m, mobile
Waist rope, then inboard pin is carried, pin hook is moved forward, proceeds to setting defect elimination.Therefore, traditional defect elimination mode, operating personnel go along the line
Enter not only to overcome that body is hanging, is difficult to the difficulty that makes power, and advance slowly, the outlet time is long, physical demands is big, work effect
Rate is low, and the psychological pressure of personnel is huge.
The content of the invention

And it is screwed into the locking that locking nut realizes cage door.
Preferably, cage fence and cage door include the cross bar of montant and its protective action to play a supportive role, montant with
By being welded and fixed at cross-car.
Preferably, the wheel groove depth of head pulley and auxiliary pulley is all higher than cable diameter.
Preferably, operation cage integrally uses symmetrical structure.
Preferably, lock strap is U-shaped structure, and two through holes in lock strap are coaxially so that clamping screw passes through.
Preferably, the center of the bottom of operation cage also installs stable lead additional.
The device have the advantages that：
1. operation cage is directly fixedly connected with main wheel frame, alleviates and problem is rocked present in operation process；And main wheel
Frame has longer size, further improves the stability on direct of travel and avoids toppling；Possesses the accessory whorl that can be rotated manually
Frame changes contact situation of the head pulley with cable so as to realize that obstacle detouring is without hindrance current.
2. realize the disengaging of operating personnel using cage door, and be equipped with door lock mechanism realize the locking of cage door and operation cage from
And meet the requirement of safety work.
3. door lock mechanism is simple in construction, reliable and stable, all parts can be obtained by common procurement, reduce further
Manufacturing cost.
4. the wheel groove depth of head pulley and auxiliary pulley is all higher than the diameter of cable, so that head pulley and auxiliary pulley and cable
Coordinate more firm stable, avoid that off-line situation occurs during traveling so as to ensure safety of advancing.
5. operation cage integrally uses symmetrical structure, and is equipped with stable lead, so as to improve in operation process because making
Stability during industry personnel activity, mitigate the psychological burden of operating personnel.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Fig. 1 to 5, a kind of Operation Van of long-span electric transmission line maintenance, including operation cage, it is horizontally arranged at
Main wheel frame 4 at the top of operation cage, and the head pulley 5 being movably arranged on main wheel frame 4.
Operation cage includes the bottom plate 1 stood for operating personnel, the cage fence 2 being fixed on bottom plate 1, and rotates peace
Cage door 3 on cage fence 2；Cage door 3 can outwardly open around rotary shaft to be passed in and out for operating personnel, can also pass through cage door
Door lock mechanism on 3 movable ends pins cage door 3 and cage fence 2 to ensure the safety of operating personnel.Cage fence 2 and cage door
3 include the montant that plays a supportive role and the cross bar of its protective action, montant with cross-car by being welded and fixed.Operation cage
Frame integrally uses symmetrical structure, and the center of its bottom also installs stable lead additional, so as to improve stability.
Door lock mechanism includes the lock strap 9 of U-shaped structure, clamping screw 10, and locking nut 11；Two are offered in lock strap 9
Individual coaxial through hole, the movable end of cage door 3 also offer through hole, and lock strap 9 is enclosed on cage fence 2, and clamping screw 10 can be worn
Cross lock strap 9 and through hole in cage door 3 and be screwed into the locking that locking nut 11 realizes cage door 3.
The length of main wheel frame 4 is more than the length of operation cage, and head pulley 5 is separately mounted to the both ends of main wheel frame 4；Operation cage
Also it is hinged on frame and accessory whorl frame 6 is installed, the both ends at the top of accessory whorl frame 6 is separately installed with auxiliary pulley 7, bottom is provided with handle 8, pull
Fixed handle 8 can make accessory whorl frame 6 rotate the mated condition for changing head pulley 5 and cable 12 around jointed shaft.
The wheel groove depth of head pulley 5 and auxiliary pulley 7 is all higher than the diameter of cable 12, is prevented so that cable 12 is embedded in race bottom land
Cable 12 departs from from race.
The operation principle and process of the present invention
Operating personnel locks cage door 3 after entering in operation cage, then manipulates Operation Van and is advanced along cable 12, when running into
When wire clamp or stockbridge damper, control crank 8 make accessory whorl frame 6 rotate so that positioned at front the relative activity cage body of auxiliary pulley 7 decline,
The head pulley 5 in the front of auxiliary pulley 7 is departed from cable 12, now just manipulate Operation Van and continue to make main cunning above forward
Wheel 5 clears the jumps, and then rotates backward accessory whorl frame 6 again and makes the relative activity cage body of auxiliary pulley 7 above rise so as to depart from line
Cable 12, then manipulating Operation Van makes the auxiliary pulley 7 also clear the jumps, and in this way all pulleys can be made to cross barrier successively
Hinder thing so as to realize barrier free accessibility.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
