The front end closing portion 115 is to prevent the external departure of the moving bar 120 by blocking the leading end of the rail 111 in a state where the moving bar 120 is fitted to the rail 111.

The length (m) of the rail 111 is designed in consideration of the moving length of the moving bar 120 and the installation position of the piston 125 and the adjusting spring 127.

It includes a hydraulic control valve 129 for adjusting the hydraulic pressure supplied to the piston (125). The hydraulic control valve 129 may allow hydraulic pressure to be supplied to or removed from the piston 125 through a rotationally loosening and tightening operation. In the embodiment, the hydraulic control valve 129 is provided symmetrically on both sides of one side of the vertical bar 110, so that the operator can easily operate the hydraulic control valve 129 on the left or right side of the vertical bar 110. .

2 and 4, one end of the first arm 130 is rotatably mounted to one end of the moving bar 120 via the first shaft bolt 131. The first shaft bolt 131 may be made to be able to rotate one end of the first arm 130 relative to the moving bar 120 through a loosening and tightening operation, and also one end of the first arm 130 may be moved. ) Can serve to fix the rotated state.

When the first shaft bolt 131 is rotated in the unwinding direction, the first arm 130 is rotatable 360 degrees relative to the moving bar 120. In this state, the first arm 130 is positioned perpendicular to the vertical bar 110 on the right side of the vertical bar 110 or in a direction coinciding with the vertical bar 110 or vertically on the left side of the vertical bar 110. It can be rotated to a position that is perpendicular to the bar 110.

In addition, the first arm 130 is configured to be foldable 90 degrees based on the hinge portion 133 is for the operator's work convenience.

In the indirect live working process, when the first arm 130 is rotated relative to the first shaft bolt 131 to be aligned with the vertical bar 110, interference between the first arm 130 and the insulating stick 50 is prevented. Although it can be prevented, it takes a lot of force for the operator to rotate the first arm 130 and the workability is reduced. Accordingly, the hinge portion 133 is placed on one side in the longitudinal direction of the first arm 130 so that the first arm 130 is simply folded to prevent interference with the insulating stick 50.

The first arm 130 may be divided into a fixed arm 130a and a rotating arm 130b based on the hinge portion 133, and the rotating arm 130b is folded 90 degrees relative to the fixed arm 130a. The hinge portion 133 allows the first arm 130 to be folded and unfolded.

A support clamp 150 is provided at the other end of the first arm 130 to support the insulating stick 50.

One end of the second arm 140 is rotatably mounted to the other end of the moving bar 120 via the second shaft bolt 141. The second shaft bolt 141 may allow one end of the second arm 140 to be rotatable relative to the moving bar 120 through a loosening and tightening operation, and also one end of the second arm 140 may be moved. ) Can serve to fix the rotated state.

A support clamp 160 for supporting the insulating stick 50 is provided at the other end of the second arm 140.

The second arm 140, the support clamp 160 is coupled by the joint portion 143 can be rotated up and down 360 °, left and right 180 ° or more. The rotation of the support clamp 160 up, down, 360°, and left and right 180° can move the end of the insulation stick 50 to a desired point by freely adjusting the insulation stick 50 supported by the support clamp 160 up, down, left, and right. It is possible. The joint portion 143 may be formed by applying a rotatable component such as a ball head and a ball bearing.

The lengths of the first arm 130 and the second arm 140 correspond to each other so that the two support clamps 150 and 160 can easily support the insulating stick 50 in parallel.

As shown in FIG. 4, the support clamps 150 and 160 have a C-shape that opens to the side, and support bolts 153 and 163 are fastened to one side to reduce the entrance of the C-shape so that the insulating stick inserted into the C-shape ( 50) is not to be separated from the support clamp (150,160). The insulating stick 50 inserted into the C-shape of the support clamps 150 and 160 is movable in the front-rear direction without being separated from the support clamps 150 and 160.

The support clamps 150 and 160 are joined by two bodies to form a C-shape, and a spring is provided at a portion connecting the two bodies to fasten the support bolts 153 and 163 to tighten the C-shaped opening in the tightened state, and the support bolts are narrowed. When the (153,163) is loosened, the C-shaped inlet is widened by the elastic force of the spring, so that the insulating stick 50 can be easily inserted.

Meanwhile, moving wheels 135 are provided at both ends of the moving bar 120 so that the moving bar 120 is easier to move along the rail 111.

The vertical bar 110, the moving bar 120, the first arm 130, and the second arm 140 constituting the insulating auxiliary arm 100 are made of an insulating material. The insulation material is made of materials with excellent insulation performance, such as bakelite, polycarbonate, and epoxy glass. This is to ensure that the insulating auxiliary arm 100 maintains the insulation performance even when the electricity is in contact with a pressurized wire or device.

However, when considering the work convenience of the operator, the hinge portion 133 is provided on the first arm 130 and the joint portion 143 is provided on the second arm 140 to support the insulating stick 50 to indirect live-line work. It is easier to perform.

Hereinafter, a method of fixing a bucket truck winch insertion-type insulating auxiliary arm according to an embodiment of the present invention to a winch of a bucket truck and mounting an insulating stick will be described.

5, the insulating auxiliary arm 100 inserts the rear end of the vertical bar 110 into the winch 20 of the bucket truck 10, and the rear end 113 of the vertical bar 110. The state inserted into the winch 20 can be fixed with a fixing pin 117.

Next, the first shaft bolt 131 is released and the first arm 130 is rotated so that the first arm 130 is vertically disposed with respect to the vertical bar 110, and then the first shaft bolt 131 is opened. Tighten again to fix the state in which the first arm 130 is arranged perpendicular to the vertical bar 110.

In the same way, by loosening the second shaft bolt 141 and rotating the second arm 140, the second arm 140 is disposed perpendicular to the vertical bar 110, and then the second shaft bolt 141 is opened. Tighten the second arm 140 to be positioned perpendicular to the vertical bar 110.

Next, the insulating stick 50 is fitted to the support clamp 150 of the first arm 130 and the support clamp 160 of the second arm 140, and the support bolts 153 and 163 of each of the support clamps 150 and 160 are provided. Tighten each) so that the insulating stick 50 is supported by the support clamps 150 and 160.

Then, the insulating stick 50 is supported on the insulating auxiliary arm 100 fixed to the winch 20.

In this state, as shown in FIG. 6, the vertical bar 110 adjusts the winch 20 toward the front top, and grips the first arm 130 or the second arm 140 and pushes it forward. . Then, by moving the first arm 130 or the second arm 140 forward, the moving bar 120 moves forward along the rail 111, and accordingly fixed to the moving bar 120 The first arm 130 and the second arm 140 move together in front of the vertical bar 110. For reference, the adjustment of the winch 20 uses hydraulic pressure and is a known technique, so a detailed description will be omitted.

In the process of the moving bar 120 moving along the rail 111, the adjusting spring 127 adjusts the moving speed of the moving bar 120, so that the first arm 130 and the second arm 140 are moved. The length-adjusting configuration is more finely controlled.

When the first arm 130 and the second arm 140 are moved to the front of the vertical bar 110, the hydraulic control valve 129 is released to supply hydraulic pressure to the piston 125. Then, the state in which the moving bar 120 is moved forward from the rail 111 is pushed up and fixed by the hydraulic pressure supplied to the piston 125.

When the state in which the first arm 130 and the second arm 140 are moved forward of the vertical bar 110 is fixed by the hydraulic pressure supplied to the piston, the operator grips the insulating stick 50 and moves it back and forth. Indirect live-line operations such as wire cutting, coating, sleeve compression, sleeve cover installation, bypass clamp fastening, etc. can be performed.

At this time, a cutter, a peeler, and a compressor may be attached to the tip of the insulating stick 50, and a cutter, a peeler, and a compressor may be operated by operating a lever or the like at the rear end of the insulating stick.

In the case of FIG. 6, since the insulating stick 50 is supported by two support clamps 150 and 160, it can be adjusted in the front-rear direction within the support clamps 150 and 160, and in the front-back, up, down, left, and right directions by the adjustment function of the winch 20. Degree adjustment is possible. In addition, since the supporting clamps 150 and 160 support the insulating stick 50, the lifting load of the insulating stick 50 is not burdened to the operator.

Meanwhile, as illustrated in FIG. 7, the insulating stick 50 is pulled out of the support clamp 150 of the first arm 130. In addition, the first arm 130 is folded 90 degrees based on the hinge portion 133 to prevent interference between the insulating stick 50 and the first arm 130.

In this state, the insulating stick 50 is supported only by the support clamp 160 of the second arm 140. In addition, since the support clamp 160 is connected to the second arm 140 by the joint portion 143, the insulation stick 50 is more freely adjusted up, down, left, and right to adjust the end of the insulation stick 50 to a desired point. Can move.

For example, as illustrated in FIG. 8, when the operation of attaching the peeler to the tip of the insulation stick 50 and performing the work of peeling the electric wire is performed, the insulation stick 50 must be adjusted more freely. Therefore, the insulating stick 50 is supported by only one supporting clamp 160 of the second arm 140, and the operator grips the lower end of the insulating stick 50 and fine-adjusts the insulating stick 50 back, forth, up, down, left, and right. Peeling can be performed.

In addition, as illustrated in FIG. 9, when the cutter is attached to the tip of the insulating stick 50 and the operation of cutting the electric wire is performed, the insulating stick 50 must be supported more stably. Accordingly, the insulating stick 50 is supported by two supporting clamps 150 of the first arm 130 and two supporting clamps 160 of the second arm 140, and the operator grips the lower end of the insulating stick 50 and insulates it. Cutting the jumper wire can be performed while adjusting (50).

The above-described insulating auxiliary arm 100 of the present invention can be securely fixed by inserting it into the winch of the bucket truck, and the insulating auxiliary arm can be finely controlled back, forth, up, down, left, and right by the winch adjustment function of the bucket truck. The tip (end) of the can be moved to the desired point.

In addition, since the first arm of the present invention is foldable, when the insulating stick is supported by only the second arm, interference between the insulating stick and the first arm is prevented, and the direction of the insulating stick can be adjusted more easily.

In addition, in the second arm of the present invention, since the supporting clamp supporting the insulating stick is connected to the second arm in an articulated manner, the insulating stick installed in the supporting arm of the second arm can be freely precisely adjusted back, forth, left and right, and the tip of the insulating stick. Can move freely to the desired point.

In addition, according to the present invention, since the insulating stick is attached to the first arm and the second arm or the second arm, the work tool is attached to the tip of the insulating stick to perform an indirect live-line operation. Since the lifting load burden is reduced and the insulating auxiliary arm prevents electric shock of workers, it can contribute to the settlement of the indirect live method.

In addition, since the insulating auxiliary arm of the present invention is made of a material having excellent insulating performance, it is possible to protect an operator from an electric shock accident even when electricity is in contact with a pressurized wire or device.
