At present when electric operating personnel need to change current transformer to switch cubicle, generally require many people and coordinate, adopt the mode operation that manpower lift to move is changed. The defect of do so is it is obvious that first is need more manpower, and second is poor stability, it is easy to staff or equipment self are caused damage, and the 3rd is facilitate not, inefficiency, length consuming time.
Summary of the invention
It is an object of the invention to provide a kind of hydraulic pressure push-in type current transformer more changing device, it is possible to shorten the replacing construction of current transformer, and improve personnel, device security.
A kind of hydraulic pressure push-in type current transformer more changing device, it is particular in that: include base, it is installed with hydraulic jack on the base, in these hydraulic jack both sides, a piece support column is each installed, wherein the bottom of every support column is all hinged on base, also include supporting platform, the bottom surface of this support platform is fixed with link, this link is hinged with the piston rod head of aforementioned hydraulic jack, 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 made up of two U-shaped framves being connected by top, and two tops of one of them U-shaped frame are hollow pipe, and the two of another U-shaped frame tops are inserted in these two hollow pipes respectively and two U-shaped framves are detachably connected by securing member.
On each hollow pipe of U-shaped top of the trellis, wherein all have at least two through hole, it is thus possible to regulate the distance between two U-shaped framves by changing the installation site of securing member.
Wherein be mounted on auxiliary connecting rod in the outside of two support columns, one end of every auxiliary connecting rod and base be hinged and its other end with to support platform hinged.
Wherein the centre of every auxiliary connecting rod all disconnects becomes two sections, and gap is provided with a two-way sleeve, each through threadeding between these two-way sleeve and two sections of this disconnection.
Wherein support platform and include one flat plate, this flat board is provided with riser one piece vertical with this flat board, this riser has connecting hole or link slot.
After adopting the more changing device of the present invention, instead of 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, substantially reduce current transformer replacing construction, improve working performance, it is ensured that power supply reliability.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention is a kind of hydraulic pressure push-in type current transformer more changing device, including base 4, this base 4 is installed with hydraulic jack 6, in these hydraulic jack 6 both sides, a piece support column 7 is each installed, wherein the bottom of every support column 7 is all hinged on base 4, also include supporting platform, the bottom surface of this support platform is 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, for instance 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 made up of two U-shaped framves being connected by top, and wherein two tops of the first U-shaped frame are hollow pipe, and two tops of the second U-shaped frame are inserted in these two hollow pipes respectively and two U-shaped framves are detachably connected by securing member. On each hollow pipe of U-shaped top of the trellis, additionally all have at least two through hole, it is thus possible to regulate the distance between two U-shaped framves by changing the installation site of securing member. Or on each hollow pipe, all have a through hole, but each have two or more through holes on two tops of the second U-shaped frame, also can realize same effect and namely regulate spacing.
Wherein also be mounted on auxiliary connecting rod 5 in the outside of two support columns 7, one end of every auxiliary connecting rod 5 is all hinged with base 4 and its other end all with to support platform hinged, be used for making support platform remain stable for. All disconnect and by a two-way sleeve connection in the middle of every auxiliary connecting rod 5, by rotating the entire length of this two-way sleeve and scalable auxiliary connecting rod 5, thus changing the angle of inclination supporting platform.
This support platform includes one flat plate 2, is provided with riser 1 one piece vertical with this flat board 2, has connecting hole or link slot on this riser 1 on this flat board 2.
The using method of the present invention is:
First placement current transformer on platform is being supported, and be connected by riser 1 and current transformer are fixing, current transformer is shifted onto by switch cubicle by the more changing device then passing through the present invention, and manual operation hydraulic jack 6 can by the height adjustment of current transformer to correct position and send into and install current transformer in switch cubicle.
