Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a hanging wheel for straight lines, and relates to a hanging wheel used for extending work on straight paths of power or communication cables.

[Conventional technology and its problems]

Conventional hanging wheels used for straight routes in cable extension work are designed so that the hanging wire grip part provided on the frame of the hanging wheel is opened, the wire is passed through the hanging wire, and the hanging wheel is attached to the hanging wire using a tightening screw. It's getting old.

Conventional hanging wheels have the above-mentioned configuration, so when attaching them to a hanging line, it is necessary to approach the hanging line using a ladder or a spacecraft and operate the tightening screws on the hanging wheel. It is. Needless to say, such work is unstable and inefficient.

Therefore, the purpose of this invention is to solve the above problems by making it possible to perform the installation work from the ground.

[Means for solving problems]

In order to solve the above problems, this invention provides a downwardly bent hook on the top of the frame that supports the roller, and a non-return claw that can be opened and closed at the open end of the locking groove formed between the hook and the frame. established,
A hanging line positioning recess is formed on the inner edge of the hook, a vertical slide hole is formed along the locking groove in the frame, a slider is inserted into the slide hole, and a regulating plate is provided integrally with the slider. The size of the shape is such that the end edge approaches the recess at the lower end of the slide and comes into contact with the suspension line, and the recess is opened at the upper end, and a downward biasing force is applied to the regulating plate by a spring. death,
Further, the regulating plate is provided with a protrusion for engaging the operating rod located below the upper end of the frame.

[Effect]

The upper end of the frame is engaged with the upper end of the operating rod to raise the push-up member of the operating rod, thereby raising the regulation plate. In this state, lift the operating rod and bring it close to the hanging wire, and when the check claw hits the hanging wire, the check claw falls inward, the locking groove of the hook is opened, and the hanging wire enters the depth of the locking groove. Thereafter, the operating rod is rotated in the opposite direction to lower the push-up member, and when the operating rod is removed from the hanging wheel, the regulating plate is lowered and the hanging wire is held between the regulating plate and the recess in the inner edge of the locking groove.

〔Example〕

As shown in FIGS. 1 and 2, the linear wire suspension wheel of this invention has a roller 2 rotatably supported at the lower end of a frame 1 having an inverted U shape as a whole.

Frame 1 is fixed frame 3 and movable frame 4
The movable frame 4 is detachably connected to the fixed frame 3 by wing bolts 5 above the rollers 2. When the butterfly bolt 5 is removed and the movable frame 4 is rotated by a required angle around the axis of the roller 2, a gap is created between the movable frame 4 and the fixed frame 3, and the cable 6 is inserted through the gap and placed on the roller 2.

The fixed frame 3 extends above the above-mentioned coupling portion, and a downwardly bent hook 7 is provided on the outside of the extended portion. This hook 7
A check claw 9 that can be opened and closed is provided at the open end of a locking groove 8 formed between the fixed frame 3 and the locking groove 8 .

The non-return claw 9 is rotatably attached to the fixed frame 3 by a pin 10, and its tip is engaged with the inside of a stopper pin 11 provided at the end of the hook 7. A biasing force in the direction is applied by a spring 12.

A recess 14 for positioning the hanging wire 13 is formed at the inner edge of the hook 7 at a deep position.

Moreover, the fixed frame 3 along the above-mentioned locking groove 8
A vertically long slide hole 15 is formed in the portion. A slider 16 (see FIG. 3) is inserted into this slide hole 15, and the slider 1
A regulating plate 17 is integrally attached to 6.

The regulating plate 17 moves up and down along the surface of the fixed frame 3 as the slider 16 slides. The shape and size of the regulating plate 17 are such that when the slider 16 is at the lower end, a part of its edge approaches the recess 14;
The suspension wire 13 is held between the recess 14 and the slider 16 is formed in a size that separates from the recess 14 when the slider 16 is at the upper end.

Further, a coil spring 18 parallel to the slide hole 15 is stretched between the end edge of the regulating plate 17 opposite to the above-mentioned edge and the fixed frame 3, and the regulating plate 1
7 is given a downward biasing force. Furthermore, an operating rod engaging protrusion 19 that protrudes laterally is provided on the edge of the regulating plate 17 that engages the coil spring 18 . This protrusion 19 is formed in the fixed frame 3 in the shape of a rectangular frame, and is located below the upper end of the fixed frame 3.

Engagement holes 21 and 21' for the operating rod 20 are formed in the upper and lower surfaces of the protrusion 19, respectively.

As shown in FIG. 3, the operating rod 20 has a joint 22 detachably attached to its upper end, and a threaded rod 22' fixed to the joint 22. The arm 23 is fixed thereto, and a push-up member 24 is screwed onto the threaded rod 22'. On the lower surface of the arm 23, protrusions 25 and 26 are formed at the tip and in the middle, and on the upper surface of the push-up member 24, there is a protrusion 2 opposing the protrusion 26 in the middle.
7 is formed.

Note that an attachment frame 28 is provided protruding from the side of the fixed frame 3 for attachment to a portion other than the hanging wire 13.

The hanging wheel according to the embodiment of this invention has the above structure, and its operation will be explained next.

With the joint 22 separated from the operating rod 20, the protrusion 25 at the tip of the arm 23 is engaged with the upper end of the fixed frame 3 of the hanging wheel, and the protrusion 1
Insert the protrusion 27 of the push-up member 24 into the hole 21 on the lower surface of the push-up member 9 (see FIG. 2). When the threaded rod 22' is rotated from the above state, the push-up member 24 rises,
The regulating plate 17 rises along the slide hole 15 and leaves the recess 14 (see FIG. 3).

Next, the above-described joint 22 is connected to the upper end of the operating rod 20, and the operator lifts the hanging wheel to the height of the hanging wire 13 by holding the operating rod 20. When the check claw 9 is pressed against the hanging wire 13, the check claw 9 falls inward and the hanging wire 13 enters the locking groove 8, as shown by the two-dot chain line in FIG. When the operating rod 20 is lowered slightly, the hanging wire 13 enters the deep part of the locking groove 8. Next, the operating rod 20
When the threaded rod 22' is rotated in the reverse direction, the push-up member 24 is lowered, and at the same time, the regulating plate 17 is lowered by the biasing force of the coil spring 18.
When the push-down member 24 descends greatly and the operating rod 20 is removed from the hanging wheel, the regulating plate 17 returns to the lowest end and the hanging wire 13 is held between its edge and the recess 14.

If it is not attached to the hanging wire 13, the band 3 of the utility pole 29 is attached using the mounting frame 28 as shown in Fig. 4.
0. It can also be attached to an arm or the like provided on the telephone pole 29.

〔effect〕

As mentioned above, this invention is equipped with a non-return claw that can be opened and closed to attach to the hanging wire, and a regulating plate for holding the hanging wire, and the regulating plate can be operated by an operating rod. This has the effect that the hanging wheel can be installed from the ground.
