The replacing device is stable in movement, convenient to use, low in cost and basically free of maintenance cost in the later period. Workers can be reduced to 2 persons, so that the replacing time of the current transformer is greatly shortened, the working performance is improved, and the power supply reliability is ensured.

Description

More changing device of hydraulic pressure push-in type current transformer
Technical field
The present invention relates to more changing device of a kind of hydraulic pressure push-in type current transformer.
Background technology
When electric operating personnel need to change current transformer to switch cubicle, often need many people to coordinate, the mode operation that adopts manpower lift to move to change at present.The defect of doing so clearly, the firstth, need more manpower, the secondth, poor stability, easily causes damage to staff or equipment self, the 3rd is to facilitate not, inefficiency, length consuming time.
Summary of the invention
The object of this invention is to provide more changing device of a kind of hydraulic pressure push-in type current transformer, can shorten the replacing time of current transformer, and raising personnel, device security.
More changing device of a kind of hydraulic pressure push-in type current transformer, its special feature is: comprise base, on this base, be installed with hydraulic jack, in these hydraulic jack both sides, a support column is installed separately, wherein the bottom of every support column is all hinged on base, also comprise support platform, on the bottom surface of this support platform, be fixed with link, the piston rod head of this link and aforementioned hydraulic jack is hinged, and this link is also hinged with the top of two support columns simultaneously.
Wherein the angle between hydraulic jack and base is 45-80 degree.
Wherein base is rectangle, is separately installed with two universal wheels and two directional wheels on four angles of this base.
Wherein base is comprised of two U-shaped of being connected by top, and one of them two top of U-shaped is hollow pipe, and insert respectively in these two hollow pipes at another two tops of U-shaped and two U-shaped by securing member, be detachably connected.
Wherein on each hollow pipe of U-shaped top of the trellis, all have at least two through holes, thus the distance between regulating two U-shaped by the installation site of change securing member.
Wherein in the outside of two support columns, auxiliary connecting rod is all installed, one end of every auxiliary connecting rod and base is hinged and its other end and support platform are hinged.
Wherein the centre of every auxiliary connecting rod all disconnects becomes two sections, and gap is provided with a two-way sleeve, between two sections of this two-way sleeve and this disconnection, is all threaded connection.
Wherein support platform comprises one flat plate, and a riser vertical with this flat board is installed on this flat board, has connecting hole or link slot on this riser.
Adopt after more changing device of the present invention, replaced dependent manual operation, more changing device self moves stable, easy to use, with low cost, the later stage is substantially without maintenance cost, and staff can reduce to 2 people, greatly shorten current transformer and changed the time, improved operating efficiency, guaranteed power supply reliability.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is more changing device of a kind of hydraulic pressure push-in type current transformer, comprise base 4, on this base 4, be installed with hydraulic jack 6, in these hydraulic jack 6 both sides, a support column 7 is installed separately, wherein the bottom of every support column 7 is all hinged on base 4, also comprise support platform, on the bottom surface of this support platform, be fixed with link 3, this link 3 is hinged with the piston rod head of aforementioned hydraulic jack 6, and this link 3 is also hinged with the top of two support columns 7 simultaneously.
Wherein the angle between hydraulic jack 6 and base 4 is 45-80 degree, and for example angle is 70 degree, and base 4 is rectangle, is separately installed with two universal wheels and two directional wheels on four angles of this base 4.This base 4 is specifically comprised of two U-shaped of being connected by top, and wherein first U-shaped two tops are hollow pipe, and insert respectively in these two hollow pipes at two tops of second U-shaped and two U-shaped by securing member, be detachably connected.On each hollow pipe of U-shaped top of the trellis, all have at least two through holes in addition, thus the distance between regulating two U-shaped by the installation site of change securing member.Or on each hollow pipe, all have a through hole, but have separately two or more through holes on two tops of second U-shaped, also can realize same effect is spacing.
Wherein in the outside of two support columns 7, auxiliary connecting rod 5 is also all installed, all its other end is all hinged with support platform with base 4 is hinged in one end of every auxiliary connecting rod 5, for making support platform keep stable.In the middle of every auxiliary connecting rod 5, all disconnect and connect by a two-way sleeve, by rotating the entire length that this two-way sleeve is adjustable auxiliary connecting rod 5, thus the angle of inclination of change support platform.
This support platform comprises one flat plate 2, and a riser 1 vertical with this flat board 2 is installed on this flat board 2, on this riser 1, has connecting hole or link slot.
Using method of the present invention is:
First in support platform, place current transformer, and be fixedly connected with current transformer by riser 1, then by more changing device of the present invention, current transformer is shifted onto by switch cubicle, manual operation hydraulic jack 6 can be by the Height Adjustment of current transformer to correct position and send into and install current transformer in switch cubicle.
