Abstract
The utility model discloses a dolly structure used for installing a current transformer of an intermediate switch cabinet. A set of link mechanism is arranged on a frame (9) with bottom wheels; the lower part of the frame (9) is fixed with a supporting seat (1); the middle part and the upper part of the frame (9) are fixed with two rotating shafts (4, 6); a lever (2) is arranged on the supporting seat (1); the lever (2) is connected with the middle rotating shaft (4) by a connecting rod (3); the middle rotating shaft (4) is connected with an upper rotating shaft (6) by a connecting rod (5); and a current transformer installation plate (7) is fixed on the upper rotating shaft (6). The mechanism effectively solves the time-wasting and effort-wasting disadvantages of the current transformer during the installation process of the intermediate switch cabinet, leads the installation of the current transformer to be convenient and fast, and improves labor efficiency.
Description
Technical field
The utility model relates to a kind of medium voltage electricity distribution system, is used in intermediate switchgear cabinet current transformer erection unit, and particularly a kind of current transformer is installed and used trolley body.
Background technology
Intermediate switchgear cabinet is widely used in the medium voltage electricity distribution system.For adapting to user installation maintenance needs easily, switch cubicle overhauls after mostly being cabinet at present, and current transformer need be lifted on the big bent plate.But relatively heavy because of the current transformer profile, very inconvenient in installation process, promptly time-consuming effort again greatly reduces the efficiency of assembling of switch cubicle.At present, still there is not a kind of time saving and energy saving intermediate switchgear cabinet current transformer erection unit.
Summary of the invention
The purpose of this utility model is that design a kind ofly can reduce labour intensity greatly, can improve the efficiency of assembling of switch cubicle, and the intermediate switchgear cabinet current transformer is installed the trolley body of usefulness.
The technical solution adopted in the utility model is: a kind of intermediate switchgear cabinet current transformer is installed and is used trolley body, have be provided with on the vehicle frame of return pulley one the cover linkage, be fixed with a bearing in the vehicle frame bottom, be fixed with two rotating shafts at vehicle frame middle part and top, bearing is provided with a lever, lever links to each other with the middle part rotating shaft by connecting rod, and the middle part rotating shaft links to each other with the top rotating shaft by connecting rod again, is fixed with a current transformer mounting panel in the rotating shaft of top.
The intermediate switchgear cabinet current transformer that the utility model provides is installed and is used trolley body, utilize lever principle, drive a cover linkage with the short arm of force end of lever, linkage drives the rotating shaft that current transformer is housed and rotates, and is promoted to suitable installation site thereby order about current transformer.Efficiently solve current transformer time-consuming drawback of effort again in the intermediate switchgear cabinet installation process, make current transformer convenient and swift, effectively raise labour efficiency in installation process.
Description of drawings
Structural representation when Fig. 1 is positioned at the current transformer initial position for the installation of the utility model intermediate switchgear cabinet current transformer with trolley body embodiment;
Structural representation when Fig. 2 moves to the current transformer installation site for the installation of the utility model intermediate switchgear cabinet current transformer with trolley body the foregoing description.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, bearing 2, lever 3, connecting rod 4, rotating shaft 5, connecting rod 6, rotating shaft 7, mounting panel 8, current transformer 9, vehicle frame
As shown in the figure, it is that a cover linkage is set on the vehicle frame 9 that has return pulley that the utility model intermediate switchgear cabinet current transformer is installed with trolley body, fix a bearing 1 in vehicle frame 9 bottoms, be fixed with two rotating shafts 4,6 at vehicle frame 9 middle parts and top, bearing 1 is provided with a lever 2, lever 2 links to each other with middle part rotating shaft 4 by connecting rod 3, and middle part rotating shaft 4 links to each other with top rotating shaft 6 by connecting rod 5 again, is fixed with a current transformer mounting panel 7 in the top rotating shaft 6.
When the long arm of force end of lever 2 is subjected to downward power, the short arm of force end of lever 2 drivening rod 3 that moves upward moves upward, connecting rod 3 drives rotating shaft 4 and rotates counterclockwise, rotating shaft 4 rotates counterclockwise drivening rod 5 and moves downward, connecting rod 5 moves downward drive rotating shaft 6 and clockwise rotates, rotating shaft 6 clockwise rotates and drives mounting panel 7 rotations, and mounting panel 7 rotating band streaming current instrument transformers rotate and also upwards are promoted to the installation site.
Claims (1)
