In order to provide a kind of moveable structure of isolated insulation baffle plate horizontal direction that is stable, reliable, that easily realize, the first isolated insulation baffle plate being provided with horizontal draw-in groove, vertical rack being provided with the buckle suitable with draw-in groove; Buckle comprises the cylinder be fixed on vertical rack, arranges the deduction cap on cylinder top; The diameter of deduction cap is greater than the width of draw-in groove.
Back seat framework left and right sides wall is respectively provided with one group of bolt hole, and crossbeam is bolted on bolt hole.
In order to improve the mobile stationarity of the first isolated insulation baffle plate, and ensure that isolated insulation baffle plate can not drop; Crossbeam is provided with the guiding draw-in groove with the first isolated insulation baffle plate adaptation.
In order to make the frictional force of horizontal draw-in groove and buckle reduce, improve operating handle, and the useful life of dolly, cylinder is bearing arrangement.
More steady in order to make the horizontal direction of the first isolated insulation baffle plate on crossbeam move, horizontal draw-in groove is provided with two on every block first isolated insulation baffle plate, and two horizontal draw-in grooves are separately positioned on the upper-lower position of the first isolated insulation baffle plate, and are parallel to each other.
Preferably, the first isolated insulation baffle plate and the second isolated insulation baffle plate are as epoxy resin board.
Preferably, the second insulation-isolation baffle 10 and two contour settings of vertical rack 7.
In order to improve the flexibility of dolly, and simplified structure, bottom support frame is square shaped as frame shape, and bottom it, each device of the right and left has two Universal wheels.
, there is the danger of getting an electric shock, ensured the life safety of staff in the beneficial effects of the utility model: the first isolated insulation baffle plate and the second isolated insulation baffle plate effectively avoid staff when operation.Meanwhile, can the first isolated insulation baffle plate of regulating of horizontal direction and vertical direction, the demand of the switch cubicle of dissimilar or electric pressure can be met, highly versatile.
The utility model effectively can solve existing baffle plate or baffle plate dolly poor reliability, the problem that versatility is low, effectively avoids operating personnel to get an electric shock injures and deaths danger.And structure simple, be easy to realize, high-tension switch cabinet insulation barrier field can be widely used in.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure event schematic diagram after Fig. 1 removes isolated insulation baffle plate.
Fig. 3 is the end view of bottom support frame and back seat framework.
Embodiment
Embodiment, a kind of insulation barrier dolly for high-tension switch cabinet as shown in Figure 1 to Figure 3, comprise bottom support frame 1, also comprise the back seat framework 3 that vertical base support frame 1 is arranged, back seat framework 3 is provided with Height Adjustable crossbeam 8, crossbeam 8 is provided with two vertical racks 7, every root vertical rack 7 being all provided with device between one piece of removable first isolated insulation baffle plate of horizontal direction, 4, two vertical racks 7 has immovable second insulation-isolation baffle 10; Bottom support frame 1 is arranged one group of Universal wheel 2.In the design of the second insulation-isolation baffle 10, from the neat of entirety and the needs, the second insulation-isolation baffle 10 and the two contour settings of vertical rack 7 that meet isolation.
First isolated insulation baffle plate 4 is provided with horizontal draw-in groove 6, vertical rack 7 is provided with the buckle 5 suitable with draw-in groove 6; Buckle 5 comprises the cylinder be fixed on vertical rack 7, arranges the deduction cap on cylinder top; The diameter of deduction cap is greater than the width of draw-in groove 6; So just effectively can fix isolation baffle plate makes it drop easily or to fall down.Back seat framework 3 left and right sides wall is respectively provided with one group of bolt hole 11, and crossbeam 8 is bolted on bolt hole 11.Crossbeam 8 is provided with the guiding draw-in groove 9 with the first isolated insulation baffle plate 4 adaptation; Guiding draw-in groove 9, for plugging and support the first isolated insulation baffle plate 4, makes the first isolated insulation baffle plate 4 to drop.Horizontal draw-in groove 6 is provided with two on every block first isolated insulation baffle plate 4, and two horizontal draw-in grooves 6 are separately positioned on the upper-lower position of the first isolated insulation baffle plate 4, and are parallel to each other.First isolated insulation baffle plate 4 and the second isolated insulation baffle plate are epoxy resin board.
Embodiment 2, the insulation barrier dolly for high-tension switch cabinet according to embodiment 1, bottom support frame 1 is square shaped as frame shape, and bottom it, each device of the right and left has two Universal wheels 2.The number of Universal wheel 2 does not limit to each two of both sides, and more than two just can provide good flexible rotating.Cylinder design becomes bearing arrangement; Make the transverse shifting of the first isolated insulation baffle plate 4 more flexible, and the frictional force of buckle 5 reduces, improve use feel and the useful life of insulation barrier dolly.Two piece of first isolated insulation baffle plate 4 is equipped with the warning district being convenient to print or paste the caveat as " halt, Keep Clear-High Voltage " printed words.
During work on the spot, if for 10kV switchgear, because 10kV switchgear is generally all divided into 3 layers, intermediate layer is switching layer, so when 10kV switchgear overhauls, up-down adjustment will do not carried out in the first isolated insulation baffle plate 4 position by the crossbeam 8 that lengthwise position is adjustable, directly the insulation barrier dolly being used for high-tension switch cabinet can be put into the switch cubicle that switchgear has exited, again according to the first time isolated insulation baffle plate 4 of the width adjusting dolly of switch cubicle, make the first isolated insulation baffle plate 4 and the second isolated insulation baffle plate 10 effectively can cover switch static contact and can realize the effect isolated of insulating, if for 35kV switchgear, because 35kV switchgear is generally only divided into 2 layers, switching on/off handcart is that integral type lands design, so when 35kV switchgear overhauls, switch static contact is higher with the distance on ground, just needs to regulate card slot type crossbeam 8 during switch maintenance, is first risen to suitable height, regulate the transverse width of isolation baffle plate 4 after fixing with bolt again, make to isolate baffle plate 4 and effectively can cover the effect that switch static contact can realize insulation isolation.
