[0007] Furthermore, the ladder body is made of hollow aluminum alloy material.
[0008] Furthermore, the soft contact strap is arranged at the upper middle part and the middle part of the ladder body, the soft contact strap fits tightly against the concave side of the transformer bushing, and the soft contact strap is a contact strap made of polyester double A material.
[0009] Furthermore, the support seat is provided with an arc surface that matches the 220kV transformer bushing.
[0010] Furthermore, the curved surface of the support seat is provided with anti-slip grooves.
[0011] Furthermore, an anti-skid pad is fixedly provided at the bottom end of the stable base, and an anti-skid pattern is provided at the bottom end of the anti-skid pad.
[0012] Furthermore, the cross bars of the ladder body are all provided with anti-slip bumps.
[0013] The beneficial effects of the utility model are:
[0014] The utility model is provided with a bracket, a supporting seat, a soft contact strap and a stable base. When the ladder is in use, when it is fitted on the transformer bushing, due to the extrusion of the soft contact strap by the outer side of the transformer bushing, the soft contact strap made of polyester double A material is deformed to match the arc shape of the outer side surface of the transformer bushing, so that the ladder is closely fitted with the transformer bushing. The stable base adjustment nut arranged at the bottom can better fit and fix with the transformer lifting seat, thereby increasing the stability of the ladder. The utility model improves the safety and reliability of the operating personnel, avoids increasing the cost of the device, and saves the working time of the bushing climbing operation during maintenance and testing.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example 1 Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:
[0024] A novel special tool for climbing transformer bushings comprises a ladder body 1 and a plurality of support blocks 2, a bracket 3 being fixedly arranged at the top of the ladder body 1, a support seat 4 being fixedly arranged at the other side of the bracket 3, a plurality of soft contact straps 5 being arranged in an array on the ladder body 1, the lower part of the ladder body 1 being rotatably connected to the adjacent support blocks 2 by bolts 6, and a stable base 7 being fixedly arranged at the bottom end of the support block 2.
[0025] Specifically, Figure 1-Figure 5 As shown, the ladder body 1 is made of a hollow aluminum alloy material. By setting the ladder body 1 to be hollow, the weight of the device can be reduced.
[0026] Specifically, Figure 1-Figure 5 As shown, the soft contact band 5 is arranged at the upper middle part and the middle part of the ladder body 1, and the soft contact band 5 fits tightly against the concave side of the transformer bushing. The soft contact band 5 is a contact band made of polyester double A material. By setting the soft contact band 5, when the ladder is fitted on the transformer bushing, due to the extrusion of the soft contact band 5 by the outer side of the transformer bushing, the soft contact band 5 made of polyester double A material is deformed to fit the arc shape of the outer side of the transformer bushing, thereby achieving a tight fit between the ladder and the transformer bushing.
[0027] Specifically, Figure 1-Figure 5 As shown, the support seat 4 is provided with an arc surface that matches the 220kV transformer bushing, and the surface of the arc surface of the support seat 4 is provided with anti-slip grooves. By providing the arc surface and the anti-slip grooves, the stability of the support seat 4 and the transformer bushing can be improved.
[0028] Specifically, Figure 1-Figure 5 As shown, an anti-skid pad 8 is fixedly provided at the bottom end of the stable base 7, and an anti-skid pattern is provided at the bottom end of the anti-skid pad 8. By providing the anti-skid pad 8, the stability between the stable base 7 and the transformer lifting base can be improved.
[0029] Example 2 Please refer to Figure 1-Figure 5The difference between this embodiment and embodiment 1 is that the crossbars of the ladder body 1 are all provided with anti-slip bumps, and the anti-slip bumps are provided to improve the safety of the user when climbing.
[0030] The working principle of the utility model is as follows: when in use, the support seat 4 is placed against the transformer bushing, and then the soft contact band 5 is wrapped around the transformer bushing, and then the support block 2 is rotated to adjust the stable base 7 to a suitable angle, and then the nut on the bolt 6 is tightened. When the ladder is fitted on the transformer bushing, due to the extrusion of the soft contact band 5 by the outer side of the transformer bushing, the soft contact band 5 made of polyester double A material is deformed to match the arc shape of the outer side of the transformer bushing, so that the ladder is tightly fitted with the transformer bushing.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
