Description

  The present invention relates to a compression tool cover. In detail, it is related with the compression tool cover attached to the compression tool which compresses a workpiece | work.

  Conventionally, the operation | work which branches the electric wire extended from the secondary side of the transformer arrange | positioned on the utility pole is performed. Specifically, a C-shaped sleeve is disposed at a branch point of the electric wire, and the branched electric wire is inserted into one end side of the C-shaped sleeve. And this C type sleeve is compressed with a compression tool, and a branch electric wire is fixed to an electric wire.

The compression tool includes a tool main body filled with oil, a compression head provided at the tip of the main body, and a rod-like handle provided in the main body. The tool body includes an oil tank, a cylinder, and a piston slidably provided in the cylinder (see Patent Document 1).
Then, by repeating the operation of approaching and separating the distal end side of the handle from the tool body, oil is gradually filled into the cylinder in the tool body, and the piston gradually moves toward the compression head by the pressure of this oil. Advance.

  In the operation of compressing the C-shaped sleeve with the compression tool, two workers are on the aerial work vehicle, and the compression tool is heavy, so one worker holds the compression tool, and C The mold sleeve is positioned in the compression head of the compression tool. The other worker repeats the work of gripping the handle of the compression tool and the tool body, and moving the handle closer to and away from the body.

Japanese Patent No. 2877431

  However, since a large stress acts on the compression head, the first worker concentrates on the operation of gripping the compression tool so that the C-shaped sleeve is positioned in the compression head. Therefore, there is a possibility that the finger of the first worker may be caught between the joint portion of the handle and the main body due to the operation of the second worker.

  An object of this invention is to provide the compression tool cover which can prevent a finger | toe being pinched at the time of the operation | work compressed with a compression tool.

  The compression tool cover (for example, compression tool cover 1) of this invention is a compression tool cover attached to the compression tool (for example, hydraulic compression tool 2) which compresses a workpiece | work, Comprising: The said compression tool is a 1st compression part ( For example, the compression head 21), a second compression part (for example, the piston 22) that can approach and separate from the first compression part, a rod-shaped first grip part (for example, the main body 23), and the first grip part And a rod-shaped second gripping part (for example, a handle 24) supported so as to be swingable, and swinging the second gripping part so that the distal end side of the first gripping part and the second gripping part The first compression portion and the second compression portion approach each other by approaching the distal end side of the first grip portion, and the portion of the first grip portion where the second grip portion is swingably supported (for example, support) Covering part 231).

According to the present invention, the portion where the second gripping portion of the first gripping portion is swingably supported by the compression cover is covered.
Therefore, for example, a C-shaped sleeve is disposed between the first compression unit and the second compression unit, and one worker supports the first gripping unit. In this state, another worker swings the second gripping part to bring the distal end side of the first gripping part closer to the distal end side of the second gripping part.
Even if it does in this way, an operator's finger | toe does not enter into the part by which the 2nd holding part of this 1st holding part is supported so that rocking | fluctuation is carried out, and a finger | toe is pinched at the time of the operation | work compressed with a compression tool. Can be prevented.

  The first gripping portion includes a tank (for example, a tank 232) in which a fluid is stored and a cylinder (for example, a cylinder 233), and the second compression portion is slidable in the cylinder. A piston (for example, piston 22) provided, wherein the first compression portion extends from the first gripping portion and faces the second compression portion, and swings the second gripping portion. When the tip end side of the first gripping portion and the tip end side of the second gripping portion are brought close to each other, the fluid stored in the tank in the first gripping portion flows into the cylinder, and the first compression portion And the second compression unit approach each other.

  In this way, for example, it is possible to prevent a finger from being pinched even during a compression operation using a hydraulic compression tool that is relatively heavy.

  The first compression unit (for example, the first head 21A) is connected to the first gripping unit (for example, the first handle 23A), and the second compression unit (for example, the second head 22A) is It is connected to a second grip (for example, the second handle 24A).

  In this way, for example, the finger is pinched even during the work of compressing the force applied to the first gripping portion and the second gripping portion using a manual compression tool transmitted directly to the first compression portion and the second compression portion. Can be prevented.

  Also, a first attaching / detaching part (for example, the first attaching / detaching part 111) that can be attached to and detached from the first holding part, and a second attaching / detaching part (for example, the second attaching / detaching part 112) that can be attached to and detached from the second holding part, An expandable / contractible part that connects the first attaching / detaching part and the second attaching / detaching part and covers a portion of the first gripping part that the second gripping part is swingably supported (for example, an extendable cover 110). And comprising.

Therefore, a 1st holding | grip part is passed between a 1st attachment / detachment part and an expansion-contraction part, and a 2nd holding part is passed between a 2nd attachment / detachment part and an expansion / contraction part. Next, the telescopic part is moved to a portion where the second gripping part of the first gripping part is supported so as to be swingable.
In this way, the compression tool cover can be attached to and detached from the compression tool, so that the fingers can be pinched by performing compression work by attaching the compression tool cover to the compression tool that does not prevent the fingers from being pinched. Can be prevented.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent that a finger | toe is pinched at the time of the operation | work compressed with a compression tool.
