Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the invention will be further described.
A kind of oil tank of transformer welded top ground adjustable support of diving, comprise interior screw mandrel mother 1, interior screw mandrel 2, stop bit plain cushion 3, out screw rod 4, out screw rod mother 8, square tube 9, chassis 10 and V-shaped rest 12, interior screw mandrel 2 top welding V-shaped rest 12, the support on V-shaped rest 12 both sides is provided with bolt hole, bottom is provided with stop bit plain cushion 3, and in screwing in screw mandrel mother 1, the effect of stop bit plain cushion 3 is when in restriction, screw mandrel 2 is upwards screwed into top, interior screw mandrel mother 1 can not be screwed out, even if rotate again, also can only connect out screw rod 4 to rotate up, interior screw mandrel mother 1 is fixed on the upper end of out screw rod 4, out screw rod 4 screws in out screw rod mother 8, out screw rod mother 8 is welded on square tube 9 upper end, the end face of out screw rod mother 8 and ground are put down, with concreting in underground, square tube 9 lower end is welded on and is greater than on the square iron dish of square tube cross dimensions, make out screw rod female 8 and square tube 9 firmly by pouring concrete in underground, can not be pulled out.
A kind of oil tank of transformer welded top ground adjustable supports method of diving, comprise following steps: 1. use ground adjustable support of diving to carry out, this device comprises interior screw mandrel mother 1, interior screw mandrel 2, stop bit plain cushion 3, out screw rod 4, out screw rod mother 8, square tube 9, chassis 10 and V-shaped rest 12, internal thread masthead end is provided with V-shaped rest, bottom is provided with stop bit plain cushion, and in screwing in screw mandrel mother, interior screw mandrel mother is fixed on the upper end of out screw rod, out screw rod screws in out screw rod mother, out screw rod mother is fixed on square tube upper end, the female upper end of out screw rod and ground maintain an equal level, square tube slips in ground, square tube lower end is fixed on chassis, 2. this device concreting is in underground, define permanent fixation means, during use, the bolt hole in utilizing on screw mandrel 2 upper end V-shaped rest 12, as the point of application, insert round steel and rotate interior screw mandrel 2, interior screw mandrel 2 and out screw rod 4 rotate simultaneously, by respective rotation, obtain the height basseted, again oil tank of transformer 5 casees edge or head cover of transformer 6 are fixed on interior screw mandrel upper end V-shaped rest 12, weld, when 3. not using, by rotating interior screw mandrel 2 clockwise, and driven rotary out screw rod 4, obtain the height needing to decline, until interior screw mandrel 2 end face and ground are put down, make this device slip into underground.
After interior screw mandrel runs to the height of needs, rely on and supported an edge card of workpiece in the V-shaped groove of interior screw mandrel 2 upper end V-shaped rest, in restriction, screw mandrel 2 no longer rotates.
After out screw rod mother 8 is welded on square tube 9, the end face of out screw rod mother and ground are put down, and with concreting in underground, become permanent frock facility.
For the operation speed of service is fast, the screw thread of interior screw mandrel and out screw rod makes double thread.
More specifically embodiment: after interior screw mandrel 2 screws in interior screw mandrel mother 1, install stop bit plain cushion 3, the effect of stop bit plain cushion 3 is: when screw mandrel 2 is upwards screwed into top in restriction, can not screws out interior screw mandrel mother 1, immediately rotate again, can only rotate up by related out screw rod 4, see Fig. 1.
The bolt hole that in utilizing, screw mandrel 2 upper end V-shaped rest 12 is other, is shown in Fig. 6-Fig. 7, as the point of application, insert round steel and get final product screw mandrel 2 in hand rotation, interior screw mandrel 2 and out screw rod can rotate, by each spinning, requirement flat with ground after obtaining the height and latent ground basseted, is shown in Fig. 1-Fig. 2.
3, the upper end V-shaped rest 12 of interior screw mandrel 2 is provided with V-shaped groove, in order to carry the case of oil tank of transformer 5 along edge, because V-shaped groove is pushed down along edge straight flange by the case of oil tank of transformer 5, now interior screw mandrel 2 just can not have rotated again, use plain bolt again, run through the other existing bolt hole of V-shaped groove and oil tank of transformer 5 casees along existing hole, see Fig. 6-Fig. 7, carry out connection fastening, see Fig. 3, connect fastening after, the present invention and oil box become stable integrative-structure, ensure safe construction on operating personnel to top of oil-tank horizontal plane.
Top cover rides over interior screw mandrel 2 upper end just can welding procedure.
Out screw rod mother 8 is welded on square tube 6 upper end, is cast in underground in the lump, because square tube lower end is welded with the square iron dish being greater than square tube cross dimensions, so out screw rod female 8 and square tube 6 can firmly by pouring concrete in underground, can not be pulled out, reach the object of safe construction, see Fig. 1-Fig. 2, Figure 12.
Without time of the present invention, be rotated down interior screw mandrel 2, when being pressed onto interior screw mandrel mother 1, drive out screw rod 4 is also rotated down by interior screw mandrel mother 1, until the end face of interior screw mandrel 2 flushes with mattess, sees Fig. 2.
