Embodiment Construction

[0012] Such as figure 1 As shown, the present invention is a high-voltage insulator string working surface elevating device, which includes an annular chuck 1, which is fixedly connected to one end of a support rod 3, and is opened at the other end of the support rod 3. There are through holes. Among them, the supporting rod 3 and the annular chuck 1 are specifically threaded, and the annular chuck 1 includes two half rings, which are detachably connected by fasteners between the two half rings. The inner wall of 1 is provided with a boss 2, and the boss 2 is specifically a U-shaped boss. Also included is an insulating pulley connected to the through hole on the support rod.

[0013] The using method of the present invention is:

[0014] When in use, first use the ring-shaped chuck 1 to cover the insulator, align the boss 2 on the inner wall of the ring-shaped chuck 1 with the groove on the insulator to fix it, then connect the support rod 3 to the ring-shaped chuck 1, and ...

Abstract

The invention relates to an elevating device of a working face of a high-voltage insulator chain. The elevating device is characterized by comprising a circular clamping head (1), wherein the circular clamping head (1) is fixedly connected with one end of a supporting rod (3), and a through-hole is arranged at the other end of the supporting rod (3). According to the elevating device, a hanging point which is used for raising a transmission pulley serves as a breach, a clamp is supported by an insulator chain, and the working face is elevated, so that the elevating device has the advantages that the workload is reduced, the working time is shortened and the working safety risks are reduced.

Description

technical field [0001] The invention relates to a high-voltage insulator string working surface elevating device. Background technique [0002] In the ultra-high voltage power grid lines put into operation in Northwest China, the cross-section of split conductors is large, and the stress of each phase conductor of the tension tower is between 18kN and 25kN. 23 ~ 25kg. For example, the replacement of 750kV strain-resistant single-piece insulators is a very important item in the maintenance work of 750kV lines, but the design tension of 750kV line porcelain bottles is 42kN, the weight is 23-25kg, and the weight of the replacement fixture is 48kg (replacement with electricity). Due to the heavy weight of porcelain bottles and replacement tools, it is very difficult for the staff to operate at high altitude, and the greater physical energy consumption brings great safety risks to the workers. Contents of the invention [0003] The purpose of the present invention is to provi...
