Abstract

The utility model discloses a device for removing foreign matters on live lines. The device comprises a frame, the cross section of which is omega-shaped. The head of the frame is internally provided with a limitation layer. The limitation layer is provided with a plurality of through holes. A roll ball is arranged between each through hole and the internal surface of the head of the frame. The roll balls can rotate in fixation positions. The side edges of the side wings of the frame are provided with pull lines. The side wing of the frame is provided with a spring scissor. The scissor mouth of the spring scissor protrudes out of the frame longitudinally. The handle of the spring scissor is connected with a control line. The device for removing the foreign matters on the live lines is convenient to operate; and the clearing of the hanging foreign matters can be operated by a signal person on the ground under the condition that the power is not cut off.

Description

Alive circuit removes foreign matter device

Technical field

The utility model relates to a kind of power transmission lines overhauling maintenance tool, and particularly a kind of alive circuit removes foreign matter device.

Background technology

Often have some hangers such as kite, cloth, plastic film on overhead transmission line; this type of hanger may cause short circuit mutually between transmission line; thereby reduced the safety and stability of transmission line; usually to remove such foreign matter; the rear line attendant that needs to have a power failure is climbed up transmission line by the suspension rope ladder and is cleared up; had a strong impact on resident and business electrical, and wasted time and energy, labour intensity is large.

The utility model content

Technical problem to be solved in the utility model is, provides a kind of and can remove foreign bodies on transmission lines in the situation that do not cut off the power supply, and the easy to operate foreign matter device that goes.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of alive circuit removes foreign matter device, comprise the framework that cross section is the Ω font, be provided with spacing layer in the head of described framework, be provided with some through holes on described spacing layer, between described through hole and framework head inner surface, be embedded with ball, described ball can rotate in fixed position, be provided with draught line on the flank side of described framework, be provided with spring shears on the flank of described framework, the scissors mouth of described spring shears vertically stretches out framework, and the handle of described spring shears is connected with controls line.

As preferred version of the present utility model, the A/F of described framework head, be not less than 1/2nd of head Breadth Maximum, is not more than 2/3rds of head Breadth Maximum.

As preferred version of the present utility model, the outer angle of the head of described framework and flank is 120 to 150 degree.

As preferred version of the present utility model, on described framework flank, be provided with and control the line bullport.

As preferred version of the present utility model, the through hole on described spacing layer becomes staggered and is uniformly distributed.

As preferred version of the present utility model, the edge of a knife of described spring shears is broached-tooth design.

The utility model alive circuit removes the Ω character form structure of foreign matter device, make this device can easily be insulated bar and directly hang up alive circuit, and making this device can take alive circuit rotates within the specific limits as axle, allow spring shears have suitable cut-in angle to be sheared, can process the foreign matter of multiple suspension attitude, the mode that its ball contacts with alive circuit, make this device be applicable to the cable of different-diameter, and reduced the damage to cable.The utility model alive circuit removes foreign matter device, easy to operate, can allow single in the situation that do not cut off the power supply, and completes the cleaning operation that hangs foreign matter on ground.

The accompanying drawing explanation

Fig. 1 is the structural representation that the utility model alive circuit removes foreign matter device.

Fig. 2 is the end view that the utility model alive circuit removes foreign matter device.

Mark in figure: 1 is framework, and 2 is spacing layer, and 3 is ball, and 4 is spring shears, and 5 is draught line, and 6 for controlling line, and 7 is bullport.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The utility model alive circuit removes foreign matter device as depicted in figs. 1 and 2, comprise the framework 1 that cross section is the Ω font, be provided with spacing layer 2 in the head of described framework, be provided with some through holes on described spacing layer 2, be embedded with ball 3 between described through hole and framework head inner surface, described ball 3 can rotate in fixed position, be provided with draught line 5 on the flank side of described framework 1, be provided with spring shears 4 on the flank of described framework 1, the scissors mouth of described spring shears 4 vertically stretches out framework 1, and the handle of described spring shears 4 is connected with controls line 6.

The utility model alive circuit goes in foreign matter device as depicted in figs. 1 and 2, for making this device hang up easily cable and rotating around cable, the A/F of framework 1 head is designed to be not less than 1/2nd of head Breadth Maximum, be not more than 2/3rds of head Breadth Maximum, it is 1/2nd of Breadth Maximum herein, carry out the attitude adjustment for convenience of draught line 5, the outer angle of the head of framework 1 and flank is designed to 120 to 150 degree, be 125 degree herein, for light control spring cuts 4, be designed with and control line bullport 7 on framework 1 flank, control line 6 inboard through under falling along the flank outside bullport from framework 1, making to control line 6, to act on the direction of motion of moment on spring shears 4 handles and blade coplanar, for making this device be applicable to the cable of plurality of specifications, there is good sliding, via design on spacing layer 2 becomes staggered and is uniformly distributed, for preventing that foreign matter from sliding when shearing, the edge of a knife of spring shears 4 is designed to broached-tooth design.

When the utility model alive circuit goes foreign matter device to use as depicted in figs. 1 and 2, by insulating bar or other method, this device is hung on alive circuit, by draught line 5, it is moved near the foreign matter place on the ground, according to the suspension attitude regulation draught line 5 of foreign matter, make spring shears 4 aim at the suitable place of foreign matter, then by controlling line 6 control springs, cut 4 processing foreign matters.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
