Embodiment 1

[0045] like figure 1 As shown, a working support for insulator replacement includes a working box, and the working box includes a working platform 11 .

[0046] As a specific implementation, such as Figure 12 As shown, the working platform 11 in this embodiment includes a square frame composed of profiles through welding, and the square frame is used as the skeleton of the working platform 11 . A bottom plate is arranged on the upper side of the square frame, preferably, the flat plate is fixedly connected with the square frame by screws. like figure 1 As shown, the four corners on the upper side of the working platform 11 are respectively provided with uprights 12 . Preferably, the lower end of the column 12 is fixedly connected to the square frame by welding, and a notch for avoiding the column 12 is provided on the bottom plate. A side plate 13 is arranged between two adjacent columns 12, preferably, the side plate 13 is fixedly connected to the outer surface of the co...

Embodiment 2

[0063] like Figure 15 and Figure 17 As shown, the middle part of the working platform 11 is provided with two pull rod assemblies 4 along the front and rear directions, and the middle part of the working platform 11 is evenly arranged with a plurality of first passages for accommodating the tie rod assemblies 4 along the front and rear directions. Hole 111. The tie rod assembly 4 sequentially includes an upper tie rod 41, a screw sleeve 42 and a lower pull rod 43 from top to bottom. A cross bar 413 is arranged on the upper end of the upper tie rod 41, and the cross bar 413 and the upper tie rod 41 together form a T-shaped structure. All the other structures are the same as in Embodiment 1.

[0064] Further, as Figure 16 As shown, the lower side of the cross bar 413 is respectively provided with several arc-shaped notches on the left and right sides of the upper tie rod 41 .

Abstract

The invention discloses an operation support for insulator replacement, which relates to the technical field of electric power overhaul equipment. The operation support comprises an operation platform, cantilever rods are arranged on the left side and the right side of the operation platform respectively, first pull rods are arranged on the cantilever rods in a sliding mode, and hooking assembliesare arranged at the upper ends of the first pull rods. Two pull rod assemblies are arranged on the operation platform in the front-back direction, and each pull rod assembly sequentially comprises anupper pull rod, a threaded sleeve and a lower pull rod from top to bottom. The lower end of the upper pull rod and the upper end of the lower pull rod are provided with an upper stud and a lower studrespectively, and the rotating direction of the lower stud is opposite to that of the upper stud. A rectangular bearing plate is fixedly arranged at the lower end of the lower pull rod, a plurality of rectangular first through holes are evenly formed in the operation platform in the front-back direction, and the width of the first through holes is smaller than the length of the bearing plate. Theoperation support can provide the operation platform for the insulator replacement, operation is more convenient, safety is guaranteed, and meanwhile work efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a working support for insulator replacement. Background technique [0002] Insulator replacement is an important task in the routine maintenance of transmission lines. At present, when replacing insulators, operators climb onto transmission line towers to replace damaged insulators. [0003] Since the insulators are generally installed on the outside of the cross arm of the transmission tower, the operator stands on the cross arm to operate when replacing the insulator, and the operator must squat down or climb on the transmission line for operation. This not only has potential safety hazards, but also reduces work efficiency. Contents of the invention [0004] In view of the above problems, the present invention provides a working support for insulator replacement, which can provide a working platform for insulator replacement, which is more conv...
