JPS5943775Y2 - Four-sided roller for cable guide - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a four-sided cable guide roller used in winding and unwinding work of distribution lines.

Winding of distribution lines during overhead line construction involves winding the cable onto a reel via a four-sided roller that has two horizontal rollers and two vertical rollers. Because the horizontal and vertical rollers were fixed, when winding small diameter cables, the gap between the four-sided rollers and the cable increases, which increases the amount of movement of the cable within the four-sided rollers, and causes problems when winding onto the reel. It had the disadvantage of causing irregular winding.

This invention was made in view of the above circumstances,
By pivoting two vertical rollers so that they can swing and be fixed around a vertical axis that is separate from the axis of each vertical roller, and by making it possible to change the spacing between the two vertical rollers, it is possible to produce rollers with various diameters. It is an object of the present invention to provide a four-sided roller for a cable guide that can wind a cable onto a reel without causing random winding.

Embodiments of the present invention will be described below with reference to the drawings.

Two frame bodies 2, 2' are vertically fixed to the base 1, and two horizontal rollers 3, 3' are pivoted in parallel at regular intervals above and below between the frames 2, 2'. 'It has been.

Oscillating bodies 5, 5' are pivotally supported by vertical shafts 4, 4' at one ends of the frames 2, 2' in the front-rear direction, and brackets 6 a s 6 c are fixed above and below each of the oscillating bodies 5, 5'. *6
Vertical rollers I, 7' are respectively pivoted between b v 6 d.

Rotating pins 8 for fixing the oscillators 5 and 5' are provided on the oscillators 5 and 5'.
, 8' are mounted in a swiveling manner, and as shown in FIGS.
1, the bottle 12 is slidably inserted, the upper end of the bottle 12 protrudes from the upper surface of the cylindrical body 17, the cam body 16 is pivotally attached 10 to the upper end of the bottle, and the cam body 16
By tilting the operating lever 9, the bin 12 is pulled upward, and by standing the operating lever 9 vertically, the bin 12 is lowered.

As shown in FIG. 5, the base 1 has a required number of holes 13. 13' is opened, and by aligning the fixing bottle 8.8' with the arbitrary hole 13.13' and fitting the bottle 12 into the hole 13, 13', the rocking bodies 5, 5' are fixed. Ru.

To change the position of the vertical roller 7.7', the operation of which will be explained next, is to operate the fixed bin 8.8'. Tilt the handle 9, pull out the bin 12 from the hole 13, and move the oscillating body 5.5'. Make it swingable.

Next, by swinging the swinging bodies 5, 5', both the vertical rollers 1,
7' so that the distance between them is slightly larger than the diameter of the cable to be used, the operating handles 9 of the fixed bins 8 and 8' are set vertically, the bins 12 are inserted into the holes 13 and 13', and the rocking body 5 is , 5' are fixed.

By the above-mentioned operation, it is possible to change the distance between the two vertical rollers 1, 7', and the holes 13, 13' are drilled at positions suitable for the diameters of the various gooples used.

As described above, according to the present invention, by oscillating and fixing the oscillator according to the diameter of various cables, the distance between both vertical rollers can be changed, and the amount of movement of the cable within the four-sided rollers can be adjusted appropriately. By keeping the cable within this range, it is possible to prevent the cable winding crew from winding the cable into a reel, thereby improving the efficiency of the cable winding work.
