Description
Technical field
The present invention relates to a kind of 10kV current transformers replacement operation dolly, operation in 10kV switch cubicles is especially belonged to
When the instrument that uses.
Background technology
The current transformer in outgoing line interval need to be often changed because of outlet load variations in power grid enterprises, with 10kV transformers
It is in the majority.Transformer, dismounting and installation fixed screw are embraced with manpower during replacing.Problem is：Transformer every is 10 to 20 thousand
Gram, and installing space is extremely narrow and small, highly between 40 centimetres to 100 centimetres, the laterally movable space of personnel is less than 80
Centimetre, human body work posture is extremely laborious, and the efficiency that wastes time and energy is low, undue force or strength deficiency can also cause personnel injure by a crashing object and
Equipment is smashed.Changing operation of current transformers in addition often coordinates other power failure work to carry out together, in operating personnel's shortage
Job schedule is often influenceed under present situation, delays electric power feeding time.
The content of the invention
In order to solve the above technical problems, the present invention is intended to provide a kind of 10kV current transformers replacement operation dolly, by
The 10kV current transformer replacement operation dollies, not only can easily complete current transformer conveying and position, Er Qie
In position fixing process, can guarantee that current transformer installation level is rectified, time saving and energy saving efficiency high.
To achieve the above object, present invention employs following technical proposals：A kind of 10kV current transformers replacement operation is small
Car, it includes that a fixed in position above has the dolly mobile platform of folding liftable frame, is provided with above described folding liftable frame
One rack pinion travel mechanism, the leading section of the rack pinion travel mechanism is connected to the L-type supporting plate of a fixed current transformer.
As preferred：The floor installation of described dolly mobile platform is by four movable pulleys；Pacify above dolly mobile platform
Being provided with the middle of the folding liftable frame of dress carries out the ratch governor motion of height regulation, and the side of dolly mobile platform is additionally provided with to be helped
Hand.
As preferred：Described folding liftable frame is integrally fixed by a connection ironware with rack pinion travel mechanism；
The tooth bar of the rack pinion travel mechanism be an expansion link or with specially linked into an integrated entity with an expansion link, one end of expansion link
Portion is welded with the rectangular L-shaped supporting plate to form one.
The present invention not only can easily complete current transformer by the 10kV current transformer replacement operation dollies
Conveying and positioning, and in position fixing process, can guarantee that current transformer installation level is rectified, time saving and energy saving efficiency high.
Brief description of the drawings
Fig. 1 is the positive structure schematic of one embodiment of the invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Referring to Fig. 1, a kind of 10kV electric currents of the present invention are mutual
Sensor replacement operation dolly, it includes that a fixed in position above has the dolly mobile platform 6 of folding liftable frame 5, described folding
Crane 5 is provided with a rack pinion travel mechanism 3 above, and the leading section of the rack pinion travel mechanism 3 is connected to a fixation
The L-type supporting plate 1 of current transformer.
Shown in figure, the floor installation of described dolly mobile platform 6 is by four movable pulleys；Above dolly mobile platform 6
Being provided with the middle of the folding liftable frame 5 of installation carries out the ratch governor motion 4 of height regulation, and the side of dolly mobile platform 6 also sets
It is equipped with handrail 7.
Folding liftable frame 5 of the present invention is integrally fixed by a connection ironware with rack pinion travel mechanism 3；Institute
State the tooth bar of rack pinion travel mechanism 3 for an expansion link 2 or with specially linked into an integrated entity with an expansion link, one end of expansion link
Portion is welded with the rectangular L-shaped supporting plate 1 to form one.
When using, by dolly push-in switch mutual inductor storehouse, regulation expansion bracket makes current transformer be positioned over dolly supporting plate
At right-angle surface, current transformer fixed screw is dismantled, current transformer is pulled out, then new current transformer is positioned over dolly support
At the right-angle surface of plate, push-in switch mutual inductor storehouse completes to install.When using, the weight of current transformer is born due to dolly supporting plate
Power, and installation site to be adjustable to fully horizontal laborsaving and installation effect good, and do not have because the improper personnel equipment that exerts a force is pounded
Danger, operating trolley quality it is small carrying be convenient to.
In the specific implementation, to ensure that current transformer is vertically stable to firm fixing hole, the section of supporting plate 1 can for the present invention
So that in L fonts, its back side is welded and fixed integrally with the one end of expansion link 2, tooth bar, gear travel mechanism 3 are by ironware and folding
Crane 5 is integrally fixed.Expansion link 2 uses gear as regulative mode with folding liftable frame 5, is more convenient Field Force behaviour
Make.
Above-described embodiment be only used for explaining it is of the invention open one's minds, any simple deformation knot for making by its inspiration
Structure, should all include protection scope of the present invention.
