Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As shown in Figures 1 to 6, the utility model provides a kind of device for installing stationary transformer 3, comprise the base 1 for carrying transformer 3, base 1 is provided with several sliding nut assemblies 2 for stationary transformer 3, sliding nut assembly 2 comprises can the sliding nut 21 of horizontal slip and the locating part 22 for limit slippage nut 21 rotary motion, locating part 22 is fixedly connected with base 1, and sliding nut 21 is arranged on locating part 22, for being connected with the bolt 4 of stationary transformer 3.
When transformer 3 is installed, keep flat base 1, first transformer 3 lifted by crane the height of a little higher than base 1 and winch to the top of base 1, the sliding nut assembly 2 installing hole on transformer 3 and base 1 being used for stationary transformer 3 has been carried out preliminary in place to hole.To hole in place good after, installing hole on transformer 3 is pre-installed bolt 4, now as having slightly little alignment error between the sliding nut 21 in bolt 4 and sliding nut assembly 2, slidably regulate the position of sliding nut 21, until to confirm between bolt 4 and sliding nut 21 that contraposition is unanimously and after meeting and installing and meet, slowly transformer 3 is placed on base 1, because sliding nut 21 limited 22 restriction can not rotary motion, so time can carry out pretension and fastening to bolt 4 by direct control torque spanner, until by fastening between all bolts 4 and the sliding nut 21 of correspondence, transformer 3 is completely fixed on base 1.
Owing to only needing once to lift by crane transformer 3, and sling height only needs highly slightly highlyer than base 1 can reach in place to hole operation, make easy to operate, fail safe is high.Because the sliding nut 21 for stationary transformer 3 can realize slidable adjustment, be convenient to realize when mounted installing with the contraposition of bolt 4, reduce in place to hole difficulty; After prepackage bolt lands, due to sliding nut 21 again limited 22 restriction can only slide and can not rotate, as long as therefore use torque spanner to carry out operation to bolt 4 just to reach fastening object, make whole contraposition and fastening operating process is very convenient, installation effectiveness is high, saving is artificial.And because sliding nut 21 limited 22 limits and can not rotate, therefore transformer 3 directly can be coated with locking mark after installing on the bolt head of bolt 4, if loosening appears in securing member, above the present bolt 4 of displacement final body loosened, make check for loose convenient directly perceived, more effectively can get rid of hidden danger.
In the present embodiment, locating part 22 comprises chute 221, described sliding nut 21 is embedded at also can along the length direction horizontal slip of chute 221 in chute 221, and the medial surface of described chute 221 can not rotary motion with limit slippage nut 21 near the lateral surface of sliding nut 21.In the present embodiment, chute 221 is vertically arranged on base 1, make the sliding nut 21 in chute 221 can realize the horizontal slip of above-below direction, and the installing hole of bolt 4 on transformer 3 has the space of left and right fine setting, just in time can coordinate with sliding nut 21 fine setting realizing four orientation up and down, make hole in place easy to operate.This is only about locating part 22 preferred embodiment in the utility model, also have numerous embodiments about locating part 22 in reality, if can be fixed on to coordinate on base 1, with sliding nut 21 make sliding nut 21 can either horizontal slip be limited again can not rotary motion.
In the present embodiment, base 1 is provided with the brace summer 11 for carrying transformer 3, and chute 221 is fixedly connected with brace summer 11.Under chute 221 is fixed on the loading end of brace summer 11, on loading end, corresponding chute 221 place is provided with the first ellipsoid through hole for passing for bolt 4, and the corresponding first ellipsoid through hole, bottom surface of chute 221 is also provided with the second ellipsoid through hole.First ellipsoid through hole be arranged so that bolt 4 can pass through and coordinate with sliding nut 21 when after sliding nut 21 slidable adjustment; Second ellipsoid through hole be arranged so that when bolt 4 is fastening, stop can not be caused to bolt 4 in the bottom surface of chute 221.
The process of the concrete making device for installing stationary transformer 3 of the present utility model is, first require according to the contour structure size parameter of transformer 3, weight parameter, installation dimension and the information such as product design dimensional requirement, determine that the channel-section steel model of the size of base 1, brace summer 11, brace summer 11 are joined the position dimension of brill first ellipsoid through hole and size dimension, the model of sliding nut 21, the steel plate model of chute 221, the contour structure size of chute 221 above and joined position dimension and the size dimension of brill second ellipsoid through hole.Then the parts of base 1 and sliding nut assembly 2 are processed, after machining, according to weight and the cabinet own wt determination welding process requirement of transformer 3, simultaneously according to installation dimension and the requirement of base 1 overall dimension, carry out pre-splicing spacing, after meeting the demands, carry out welding.Before sliding nut assembly 2 and brace summer 11 welding, trial assembly guarantees that sliding nut 21 can be free to slide, and guarantees that sliding nut 21 is no more than required value at vertical direction mobile space.The second ellipsoid through hole on chute 221 and the first ellipsoid through-hole alignment on brace summer 11 is guaranteed when welding.Concrete installation process is already described above, no longer repeats at this.
Below be only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, protection range of the present utility model should be considered as.
