Embodiment 1

[0042] Such as Figure 1 to Figure 4 As shown, this embodiment provides a 110KV tension rod composite insulator outlet hanging ladder, including an insulating rod 1 with an elliptical radial section, two insulating rods 1 are provided, and one end of the two insulating rods 1 is fixedly installed. The elliptical sleeve 2, the bottom of the two elliptical sleeves 2 are hingedly connected, and the two sides are fixedly connected by the connecting bolt 3 and the knurled nut 4 respectively, and the knurled nut 4 provided can be directly screwed and fastened when in use, which is convenient to use; In the embodiment, the elliptical sleeve 2 is fitted on the end of the insulating rod 1 and fixed by a rivet 11 .

[0043] The insulating rod 1 has an elliptical structure in radial cross-section, has high structural strength, and is convenient for maintenance personnel to step on and pass through, and has good passability for personnel.

[0044] In order to make the hanging ladder have...

Embodiment 2

[0061] The structure of this embodiment is the same as that of Embodiment 1, the difference is that the structure of the connecting ear 202 of one of the oval sleeves 2 is as follows: Figure 7 As shown, the connecting ear 202 of the elliptical sleeve 2 is provided with a clamping notch 2022, and the opening of the clamping notch 2022 faces upward, and the connecting bolt 3 is fixedly installed on the connecting ear 202 of another elliptical sleeve 2. When in use, the two insulated The rods 1 are docked, the screw of the connecting bolt 3 is snapped into the snap-in gap 2022 of the corresponding connecting ear 202, and the knurled nut 4 is tightened to realize the positioning connection. Compared with the connection method of the two insulating rods 1 in Embodiment 1, folding and When connecting, there is no need to disassemble the connecting bolt 3 and the knurled nut 4, which is more convenient to use and more convenient to operate.

Abstract

The invention belongs to the technical field of electric power overhaul equipment, and provides a 110KV tensile rod composite insulator outgoing line hanging ladder. The110KV tensile rod composite insulator outgoing line hanging ladder comprises two insulating rods with elliptical radial cross sections, and elliptical sleeves are fixedly mounted at one ends of the two insulating rods. The bottomsof the two elliptical sleeves are connected in a hinge joint mode, and two sides of the bottoms of the two elliptical sleeves are correspondingly and fixedly connected by a connecting bolt and a knurled nut. A cross arm clamping mechanism is fixedly mounted at the other end of one of the insulating rods, and the other end of the other insulating rod is slidably sleeved with a sleeve matched with the outer diameter of the insulating rod. The sleeve is provided with a positioning mechanism for positioning on the insulating rod, and a hanging rod is further fixedly mounted at the top of the sleeve. The 110KV tensile rod composite insulator outgoing line hanging ladder is simple and convenient to install and use, can flexibly adjust the length of use, has high universality, and has functions of disassembly and folding; and the size is greatly reduced after disassembly and folding, carrying, handling and storing are convenient, and personnel can be effectively prevented from swinging and shaking when passing, and potential safety hazards are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a 110KV tension rod composite insulator hanging ladder. Background technique [0002] During the construction and maintenance of power lines, when workers go out from the tension rod to replace the anti-vibration hammer, remove or install the drain wire, overhaul or check the clamps and fittings, etc., they need to step over the insulator to reach the cable for work. During the installation of accessories, measures should be taken to prevent tools from colliding with the organic composite insulator umbrella cover, and it is strictly forbidden to step on the upper and lower leads of the organic composite insulator during the installation process, so as to avoid damage to the organic composite insulator due to scratching and trampling. The outgoing line construction of the pole composite insulator has caused certain difficulties. [0003] At present, i...
