Abstract
The utility model discloses a paper tube mounting and demounting tooling for transformer coil overhaul. The paper tube mounting and demounting tooling comprises two yoke plates, two coupling bolts, two clamping plates, a sleeve and clamping bolts, wherein the two yoke plates are parallelly arranged at intervals, a through hole is respectively arranged at the upper end and the lower end of each yoke plate, the two coupling bolts respectively penetrate into the upper through holes and the lower through holes of the two yoke plates and are fastened through nuts, and the sleeve is sleeved into bolts arranged at the upper ends of the two yoke plates and located between the two yoke plates. One ends of the two clamping plates are respectively hinged to the bolts at the lower ends of the two yoke plates and located between the two yoke plates, a through hole is respectively arranged in the middle of each clamping plate, bottom end opposite surfaces of the two clamping plates are arc surfaces, and the clamping bolts penetrate into the through holes in the middles of the two clamping plates and clamped through nuts. The paper tube mounting and demounting tooling can facilitate mounting and demounting of a transformer coil paper tube, avoids damage and demounting of the paper tube, ensures quality of transformer coil overhaul, improves overhaul efficiency, and reduces overhaul cost.
Description
Technical field
The utility model relates to a kind of paper web dismounting frock that is used for the transformer coil maintenance.
Background technology
Transformer coil is extremely important assembly of transformer equipment, is known as the heart of transformer.Therefore guarantee in the upkeep operation that the safety of transformer coil is most important to transformer equipment.
General transformer coil internal diameter is provided with the inner ring of paper web with the protection coil; And be short-circuited or during insulation harm, repair in order the internal coil diameter side to be carried out the part when the internal coil diameter side, can only the coil inner fiber container be destroyed cutting; Take out the coil inner fiber container then; Carry out maintenance of transformer coil internal side diameter and reparation again,, then can't implement the fault restoration of transformer coil internal side diameter if the coil inner fiber container does not take out; And the cutting of the destruction of paper web is promptly wasted time and energy, and has reduced the efficient that coil is repaired, and also is damaged to internal coil diameter easily, causes new fault, and the paper web after the cutting can only do to scrap processing simultaneously, has improved the cost of overhaul.
Summary of the invention
The utility model technical problem to be solved provides a kind of paper web dismounting frock that is used for the transformer coil maintenance; Utilize this frock can conveniently implement the dismounting operation of transformer coil paper tube; Avoided the destruction of paper web to remove; Guarantee the quality of transformer coil maintenance, improved overhaul efficiency, reduced the cost of overhaul.
For solving the problems of the technologies described above; The paper web dismounting frock that the utility model is used for the transformer coil maintenance comprises two yoke plates, two attachment bolts, two clamping plates, sleeve and fishbolts; Said two yoke plate parallel interval arrange that also two ends have through hole up and down; Said two attachment bolts penetrate two through holes and fastening through nut up and down of said two yoke plates respectively; Said sleeve is inserted in said two yoke plates upper end bolt and between two yoke plates; Said two clamping plate one ends are articulated in said two yoke plate lower end bolts respectively and between two yoke plates, said two clamping plates middle part has through hole and the bottom forward surface is an arc surface, and said fishbolt penetrates the through hole at said two clamping plates middle part and clamps through nut.
Because being used for the paper web dismounting frock of transformer coil maintenance, the utility model adopted technique scheme; Be that this frock comprises two yoke plates, two attachment bolts, two clamping plates, sleeve and fishbolts; Two yoke plate parallel interval arrange that also two ends have through hole up and down; Two attachment bolts penetrate two through holes and fastening through nut up and down of two yoke plates respectively; Sleeve is inserted in two yoke plates upper end bolts and between two yoke plates; Two clamping plate one ends are articulated in two yoke plate lower end bolts respectively and between two yoke plates, and two clamping plates middle parts have through hole and the bottom forward surface is an arc surface, and fishbolt penetrates the through hole at two clamping plates middle parts and clamps through nut.This frock can conveniently be implemented the dismounting operation of transformer coil paper tube, has avoided the destruction of paper web to remove, and has guaranteed the quality of transformer coil maintenance, has improved overhaul efficiency, has reduced the cost of overhaul.
Description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is done further to specify:
Fig. 1 is used for the structural representation of the paper web dismounting frock of transformer coil maintenance for the utility model;
Fig. 2 is the end view of Fig. 1;
Fig. 3 implements the sketch map of paper web dismounting for adopting this frock.
Embodiment
As depicted in figs. 1 and 2; The paper web dismounting frock that the utility model is used for transformer coil maintenance comprises two yoke plates 1, two attachment bolts 2, two clamping plates 3, sleeve 4 and fishbolts 5; Said two yoke plate 1 parallel interval arrange that also two ends have through hole up and down; Said two attachment bolts 2 penetrate two through holes and fastening through nut up and down of said two yoke plates 1 respectively; Said sleeve 4 is inserted in said two yoke plates, 1 upper end bolt and between two yoke plates 1; Said two clamping plate 3 one ends are articulated in said two yoke plates, 1 lower end bolt respectively and between two yoke plates 1, said two clamping plate 3 middle parts have through hole and the bottom forward surface is an arc surface, and said fishbolt 5 penetrates the through hole at said two clamping plate 3 middle parts and clamps through nut.
As shown in Figure 3, when the transformer coil internal diameter overhauls, for avoiding that paper web 7 is implemented destructive dismounting; It is suitable for reading that at first at least three this frock 6 equidistance of employing are arranged at paper web 7, the fishbolt on two clamping plates of this frock unclamped, because two clamping plate one ends are articulated on the attachment bolt of lower end; Thereby two clamping plates are separately formed crack; And this crack stretched into paper web barrel suitable for reading, and tighten fishbolt then and crack is closed up and fuse with paper web, adopt this moment rope 8 to connect sleeve and travelling crane hook 9 on each frocks upper end attachment bolt; Starting driving can slowly extract paper web 7 from the transformer coil internal diameter through this frock 6; Greatly made things convenient for the upkeep operation of transformer internal diameter fault, avoided the paper web cutting to have improved overhaul efficiency the fault of transformer coil generation; This paper web also can return through this frock and be filled to the transformer coil internal diameter simultaneously, thereby has reduced the cost of overhaul.
Claims (1)
