Description

Wire Lifting Insulation Bracket

technical field

The utility model relates to a tool for lifting and supporting a phase wire in a 10kV power distribution overhead line in non-stop operation, in particular to a wire lifting insulating support.

Background technique

At present, most of the existing 10kV overhead lines in the urban area of Yingkou are horizontal multi-circuit erected on the same pole, and the working environment is relatively complicated. When the middle phase of the upper line needs to be repaired without power failure, when the insulating glove method is used to operate the bucket arm truck, due to the height limit between the lines erected on the same pole, it is difficult for live workers to perform non-power-off work while ensuring a safe distance. For example, non-stop operations such as replacing insulators, disconnecting drain wires with power, etc. The utility model 10kV distribution network overhead line non-stop working wire lifting insulation support is proposed under this background.

Utility model content

The purpose of the utility model is to provide a wire lifting insulation support, which has a simple structure and principle and is easy to operate.

In order to solve the problems existing in the prior art, the technical solution adopted by the utility model is:

The wire lifting insulation support includes an insulation support arm, a screw, a fixed wire device and a connecting part. There are four insulation support arms, the ends of which are gear-shaped and meshed with each other. The adjacent two insulation support arms The head ends are respectively connected to the two ends of the connection part, the ends of the two adjacent insulating support arms are connected by a pin, the two ends of the screw are connected to the pin, and the upper end of the connection part is connected with a fixed wire device.

The insulating support arm is U-shaped.

The screw rod is provided with threads.

One end of the screw rod is threaded, and the other end is shaft connected.

The outer side of the shaft connection end of the screw rod is hexagonal, and is matched with the wing nut, and the screw rod located at the outer end of the wing nut is a smooth structure without threads.

The smooth structure has a length of 200 mm.

The fixed wire device includes a fixed rod and a movable rod. The movable rod is provided with a circular hole, and the two ends of the spring are fixed in the circular hole, so that the movable rod can be moved up and down.

The connecting part is connected with the fixed wire device through a pin shaft.

The use method of the wire lifting insulation support includes the following steps:

(1) First, fix the wire lifting insulation bracket on the upper and lower ends of the wires, and then the operator will separate the side phase vertical bottle from the cross arm;

(2) The operator uses a wrench tool to adjust the wire lifting insulation support to a safe position suitable for the operation;

(3) Finally, the operator enters the operation area for maintenance.

The advantages and beneficial effects that the utility model has are:

The wire lifting insulation support of the utility model has four insulating support arms, the ends of which are gear-shaped and meshed with each other. The ends of the two insulating support arms are connected by a pin shaft, the two ends of the screw rod are connected with the pin shaft, and the upper end of the connecting part is connected with a fixed wire device. This structure can ensure that live workers can work without power failure while keeping a safe distance.

detailed description

As shown in Figures 1 and 2, the wire lifting insulation support of the present invention includes a U-shaped insulation support arm 8, a screw rod 10, a fixed wire device and a connecting part 7. There are four insulation support arms, and the ends thereof are geared The two adjacent insulating support arms are connected to the two ends of the connecting member 7 respectively, and the ends of the two adjacent insulating support arms are respectively connected by pins 9 and 11. As shown in FIG. 2 , one end of the screw rod 10 is threadedly connected to the pin shaft 9 , and the other end of the screw rod 10 is axially connected to the pin shaft 11 . The outer side of the shaft connection end of the screw rod is a hexagonal structure, which is convenient to use a ratchet wrench for adjustment. It is matched with the wing nut, which is convenient for manual adjustment when not in use. The screw at the outboard end of the wing nut is of smooth construction and has no threads. The smooth structure has a length of 200mm.

The upper end of the connection part is connected with a fixed wire device. The connecting part 7 is connected with the fixed wire device through the pin shaft 6 .

As shown in Figure 1, the fixed wire device includes a fixed rod and a movable rod 1, the movable rod 1 is provided with two round holes 3, and the two ends of the spring 2 are respectively fixed in the round holes 3, so that The movable rod can be moved up and down. The movable rod can facilitate the fixing of the wire.
