Description

Technical Field

[0001] The invention relates to the technical field of transformer maintenance, and in particular to a transformer maintenance high-altitude protective device and a construction method thereof. Background Art

[0002] When overhauling large transformers (such as 35kV and 110kV transformers), the maintenance operation is actually aerial work because the height of the box is as high as three meters or even higher. The current requirement for aerial work is "high hanging and low use". Usually, a safety belt hanging rod is fixed, and a hanging ring is set at the top of the hanging rod for hanging the safety belt. However, the top of the transformer box is large and many surfaces need to be overhauled. The driving safety belt hanging rod can only be fixed at one point, resulting in a small overhaul range, which is not convenient for the overhaul of the transformer box. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a transformer maintenance high-altitude protection device and a construction method thereof, so as to solve the problem of lack of safety protection during transformer box maintenance.

After the safety rope passes through the conductor ring, the two ends are fixed on the parallel groove wire clamp, and the safety belt hanging ring of the maintenance personnel is hung on the safety rope for maintenance.

[0005] Preferably, the end conductor rods and the middle conductor rods are arranged in the middle of a straight plate, the straight plate is connected to the top plate of the transformer box by bolts, and diagonal braces connected to the straight plate are provided on both sides of the end conductor rods and the middle conductor rods.

[0006] Preferably, the corner conductor rod is arranged at the corner of the L-shaped plate, the L-shaped plate is connected to the top plate of the transformer box by bolts, and a diagonal brace is provided between the corner conductor rod and the L-shaped plate.

[0007] Preferably, the side walls of the end conductor poles, the middle conductor poles and the corner conductor poles are provided with hanging rings for hanging safety belts.

[0008] Preferably, it also includes a positioning hanging plate, which is hung on the safety rope, and the positioning hanging plate is provided with a wire groove for the safety rope to pass through, and through holes are provided on both sides of the positioning hanging plate, and the safety belt hanging ring is connected to the through holes.

[0009] Preferably, the inner side wall of the wire trough is provided with a serrated protrusion.

[0010] Preferably, both sides of the positioning hanging plate gradually narrow from top to bottom.

[0011] Preferably, the safety rope is a steel wire rope.

[0012] The method for constructing a high-altitude protective device for transformer maintenance includes the following steps: Fix the end conductor rod, middle conductor rod and corner conductor rod at the edge of the top plate of the transformer box according to the maintenance needs; Then pass the safety rope through the wire ring first, and then fix the two ends of the safety rope on the parallel groove wire clamp; During maintenance, the maintenance personnel hang the safety belt hanging ring on the safety rope.

[0013] Preferably, the end of the safety rope passes through one wire groove of the parallel groove wire clamp and then passes back through another wire groove.

[0014] The present invention provides a transformer maintenance high altitude protection device and a construction method thereof, which can meet the safety protection requirements of various surfaces of large transformers during maintenance. The hanging of the safety belt hook is no longer limited to one point, and the safety belt hook can slide on the safety rope, which improves the safety protection range and flexibility.

DETAILED DESCRIPTION

[0016] like Figure 1-2 As shown, a transformer maintenance high altitude protection device includes a transformer box 1, and a plurality of safety rope conductor rods are arranged at the edge of the top of the transformer box 1, and the safety rope conductor rods include end conductor rods 2, middle conductor rods 3 and corner conductor rods 4, and conductor rings 5 ​​are arranged at the upper ends of the middle conductor rods 3 and the corner conductor rods 4, and parallel groove wire clamps 6 are arranged at the upper end of the middle conductor rods 3. After the safety rope 7 passes through the conductor ring 5, the two ends are fixed on the parallel groove wire clamps 6, and the safety belt hanging ring 8 of the maintenance personnel is hung on the safety rope 7 for maintenance. After the safety belt hanging ring 8 is hung on the safety rope 7, the safety belt hanging ring 8 can move with the maintenance personnel within a certain range.

[0017] Preferably, the end conductor rod 2 and the middle conductor rod 3 are arranged in the middle of the straight plate 9, the straight plate 9 is connected to the top plate of the transformer box 1 by bolts, and diagonal braces 10 connected to the straight plate 9 are provided on both sides of the end conductor rod 2 and the middle conductor rod 3.

[0018] Preferably, the corner conductor rod 4 is arranged at the corner of the L-shaped plate 11, the L-shaped plate 11 is connected to the top plate of the transformer box 1 by bolts, and a diagonal brace 10 is arranged between the corner conductor rod 4 and the L-shaped plate 11. The diagonal brace increases the stability of the end conductor rod 2, the middle conductor rod 3 and the corner conductor rod 4 under stress.

[0019] Preferably, the side walls of the end conductor rod 2, the middle conductor rod 3 and the corner conductor rod 4 are provided with a hanging ring 12, and the hanging ring 12 is used to hang the safety belt hanging ring 8. When the safety belt hanging ring 8 needs to be fixed at a certain point, the safety belt hanging ring 8 can be hung on the hanging ring 12.

[0020] Preferably, Figure 2 As shown, it also includes a positioning hanging plate 14, which is hung on the safety rope 7. The positioning hanging plate 14 is provided with a wire groove 15 for the safety rope 7 to pass through. Through holes 16 are provided on both sides of the positioning hanging plate 14, and the safety belt hanging ring 8 is connected to the through holes 16.

[0021] When the safety belt hanging ring 8 needs to be fixed to a certain point on the safety rope 7 , the positioning hanging plate 14 is first hung on the safety rope 7 at that point, and then the safety belt hanging ring 8 is hung in the through hole 16 .

[0022] Preferably, Figure 3 As shown, the inner side wall of the wire groove 15 is provided with a sawtooth protrusion 13. The sawtooth protrusion 13 increases the friction between the positioning hanging plate 14 and the safety rope 7 to prevent it from moving after the safety belt is hung.

[0023] Preferably, the two sides of the positioning plate 14 are gradually narrowed from top to bottom. On the one hand, the clamping of the positioning plate 14 on the safety rope 7 is increased, and on the other hand, the interval between the two through holes 16 is reduced, which is convenient for hanging the safety belt hanging ring 8. Preferably, the safety rope 7 is a steel wire rope.

[0024] The method for constructing a high-altitude protective device for transformer maintenance includes the following steps: At the edge of the top plate of the transformer box 1, fix the end conductor rod 2, the middle conductor rod 3 and the corner conductor rod 4 according to the maintenance needs; Then pass the safety rope 7 through the wire ring 5, and then fix the two ends of the safety rope 7 on the parallel groove wire clamp 6; During maintenance, the maintenance personnel hang the safety belt hanging ring 8 on the safety rope 7.

[0025] Preferably, Figure 4 As shown, the end of the safety rope 7 passes through one wire groove of the parallel groove wire clamp 6, and then passes back through the other wire groove, forming a U-shaped fold, which plays a double fastening role.

[0026] When in use, the maintenance personnel can hang the safety belt loop 8 on the safety rope 7. When the maintenance personnel move and cause the safety belt loop 8 to hit the wire ring 5, the safety belt loop 8 can be removed and hung on the next section of the safety rope 7. If the safety belt loop 8 needs to be fixed at a certain place, the safety belt loop 8 can be hung on the hanging ring 12, or the safety belt loop 8 can be hung on the through hole 16 of the positioning hanging plate 14.
