1 and 2 show one embodiment of claim 1 of the present invention. In this embodiment, the mechanical equipment for removal and recovery is not individually mounted on the chassis 1 of the overhead car, but the whole is mounted side by side on a base 2 in two rows, and the base 2 is mounted and fixed on the chassis 1. . Positioning guide device 3 consisting of guide rollers 3 ′ with tooth-shaped irregularities arranged in a horizontal and vertical arrangement at the rearmost part of base 2 to receive the transmission line W pulled down from the tower from above and below and from the left and right, and immediately before that. A ring excision device 4 consisting of a pair of hydraulically driven rotary blades 4'for cutting off the snow-prevention ring of the power transmission line, a winch 5 in front of it, and two pairs of feed rollers 6 ', 6'upper and lower in front of it. The rear hand feeding device 6, the power transmission line cutter 7 that allows the power transmission line to pass through to the final stage in front of it, the clamps 8F and 8R before and after the power transmission line cutter, and the guide rollers that are arranged in the shape of double crosses just before and after the front clamp 8F. There is a guide holding device 9 composed of 9 ', and a winding device 10 including a traverser 10a in front of it.
Is located directly behind the columns of the lifting device 11 behind the driver's seat 13.

1 and 2, the arrangement of the mechanical equipment for removal and collection on the base 2 fixed on the chassis of the overhead car has been described. Next in FIG.
The functions of the removal and recovery machinery will be explained below.
First, the positioning guide device 3 that welcomes the power transmission line W is configured by arranging two vertical and two horizontal toothed rollers 3'having tooth-shaped irregularities as shown in FIGS. 4 has tooth-shaped irregularities on the peripheral surface as shown in FIG. Since the snow transmission prevention rings 12 are scattered on the power transmission line W, the snow transmission prevention ring is caught by the rollers in the ordinary cylindrical roller and the power transmission line cannot pass between the rollers. Therefore, this guide roller 3'has a tooth profile on the peripheral surface so that the power transmission line W can be guided across the snow-prevention ring 12, and the snow-prevention ring 12 enters the recess between the tooth profiles as shown in FIG. The power transmission line W is allowed to pass between the four guide rollers 3 '.

Upper and lower parts 2 of the positioning guide device 3 in the lateral direction.
The rollers 3a ', 3a' of the book are spaced a through which a thick power transmission line can pass.
Is rotatably supported while keeping the vertical direction (Fig. 3A).
reference). As a result, it is possible to pass from the thick power transmission line to the thin power transmission line at the interval a between the upper and lower two rollers 3a 'and 3a'. On the other hand, the two vertical rollers 3b ′, 3
b'is erected rotatably with its position shifted before and after the two lateral rollers 3a ', 3a' while keeping a distance b through which a thin power transmission line can pass (see FIG. 3B). As a result, the thin power transmission line passes straight through the distance b between the two vertical rollers 3b 'and 3b', and the thick power transmission line moves the distance between the rollers 3b 'and 3b' in the horizontal direction as shown in FIG. 3B. Meander and pass.

The transmission line W, which is pulled down by the winch 5 and the upper and lower rollers 6 ', 6'of the tail feeding device 6 and advances forward, has four tooth-shaped uneven rollers 3'of the positioning guide device 3. By means of the following hydraulic cutting of the ring excision device 4 comes in precisely between the upper and lower rotary blades 4 ', 4'. FIG.
The power transmission line W with the snow accretion prevention ring 12 is attached to the upper and lower rotary blades 4
It shows the situation of passing between 'and 4'. The ring excision device 4 has upper and lower cases of hydraulic rotary drive equipment, and the respective hydraulic motors 4a, 4a project from the respective cases. A screw shaft with a handle 4b attached to the upper end is rotatably erected from the lower case, and a nut 4c screw-engaged with the screw shaft is fixed to the upper case. Therefore, the upper rotary blade 4 ′ can be adjusted up and down in a screw type by the forward and reverse rotation of the handle 4 b together with the case of the hydraulic equipment so as to cope with the change in the thickness of the power transmission line W.

The upper and lower rotary blades 4'and 4'and the power transmission line W are
If it is not aligned with the true center as shown in FIG. 6, the snow accretion prevention ring 12 cannot be cut in half by completely dividing it. For this reason, the guide positioning device 3 using the four tooth-shaped uneven rollers 3'aligns the power transmission line W with the upper and lower rotary blades 4'and 4'for positioning. When the snow-prevention ring 12 is new, it does not move because it is attached to the power transmission line W, so the rotational directions of the rotary blades 4 ′, 4 ′ do not matter, but the snow-prevention ring 12 is old and runs along the power transmission line W. When moving, as shown in FIG. 7, one of the blades pushes the snow-prevention ring 12 to advance and the other one stops in such a rotation direction that even if the snow-prevention ring 12 is movable, Cut it in half and let it fall off the power line.

In this example, the winch 5 has a maximum capacity of 3 tons, and the tension can be adjusted from 0 to 3 tons. A pair of upper and lower rollers 6 ′ and 6 ′ of the front and rear sides of the rear hand feeding device 6 hold the tail of the power transmission line W which the winch wraps and advances to the front. FIG. 8 shows the feeding device 6, in which the front and rear upper rollers have a driving hydraulic motor 6b,
The front and rear lower rollers are also provided in a lower case having a driving hydraulic motor. A screw shaft rotated by a lifting hydraulic motor 6a stands rotatably from the lower case, and a nut 6c screw-engaged with the screw shaft is provided on the upper case.
Is fixed and cannot be rotated. Therefore, according to the thickness of the power transmission line W, the lifting hydraulic motor 6a rotates the screw shaft in the forward and reverse directions to move the upper case up and down, thereby adjusting the interval between the upper and lower rollers.

[0012] The power transmission line W that has come out from the rear hand feeder 6
Is a guide holder consisting of four cylindrical rollers 9'arranged in a cross girder that sandwiches the transmission line W from above and below, and right and left, passing through a rectangular frame 7c of the cutter 7 that is still open, the clamps 8F and 8R before and after the cutter. Go through the device 9 to the winding device 10. Therefore, the power transmission line W is moved left and right by the traverser 10a that reciprocates left and right, and the reel 10b of the winding device 10b is moved.
It is evenly wound on the entire length of the outer circumference of the winding cylinder. Since the power transmission line goes through the guide holding device 9 to the traverser 10a, the power transmission line can be moved left and right by the left and right reciprocating motions of the traverser between the guide holding device 9 and the traverser as shown by the broken line in FIG. Only in the interval, the power transmission line before the guide holding device 9 does not move to the left and right, and advances from the positioning guide device 3 toward the guide holding device 9.

Similarly to the positioning guide device 3 described above, the guide holding device 9 also has two rotatable cylindrical rollers in the horizontal direction for keeping the space through which a thick power transmission line can pass vertically, and a thin power transmission line. It consists of two longitudinal cylindrical rollers that are erected rotatably in front of and behind the two lateral cylindrical rollers with a space that allows them to pass through, and between the four rollers. The thin transmission line passes straight through, and the thick transmission line meanders in the lateral direction and passes through the traverser 1.
Proceed towards 0a.

The power transmission line is pulled down from the tower, and the winding device 10
In order to wind it up on the reel, the snow-prevention ring at the front end of the transmission line pulled down from the steel tower is cut and removed with a tool and pulled forward to the guide positioning device and ring cutting device at the rear end of the car body. Pass it through the winch and wrap it around the winch, and open it by passing it through the butt hand feed device 6, front clamp 8F, cutter 7, rear clamp 8R, guide holding device 9, and traverser 10a, and close the front and rear clamps 8F and 8R to disconnect the transmission line. Fix and connect the front end of the power transmission line to the bobbin 10b, then open the front and rear clamps, rotate the bobbin 10b, and rotate the bobbin 10b according to the peripheral speed at which the bobbin winds the power line, and the winch 5 Two pairs of upper and lower rollers 6 ', 6'of the feeding device are rotationally driven to start winding the power transmission line on the winding frame through the traverser.

The winding drums are arranged alternately at equal intervals in the circumferential direction. However, as shown in FIG. 11, the power transmission line W is actually wound around the movable horizontal joint 22 held parallel to the axis of the winding device, and the fixed horizontal joint 21 fixed with a draft angle is , Is almost not in contact with the power transmission line W wound on the movable cross member 22 parallel to the axis. A regular thin electric wire can be wound into a rectangular shape with only four movable horizontal rods 22, but since the power transmission line has a large diameter and is rich in elasticity, it can be wound into a substantially round shape. Note that, for convenience of description, the fixed horizontal member 21 and the movable horizontal member 22 in FIG. 11 are a side surface of the fixed horizontal member 21, a flat surface, and a movable horizontal member 2.
Only the side surface of No. 2 is shown, and the position where the movable horizontal shaft 22 has a draft angle is shown by a chain line 22 '. As shown in FIG. 12, the actual arrangement is such that the fixed horizontal rods 21 and the movable horizontal rods 22 are alternately provided at equal intervals in the circumferential direction.

The above-mentioned fixed horizontal rail and the movable horizontal rails 21 and 22 are held in the arrangement of the winding drum, and the winding drum inner peripheral flange 17 for detachably fixing the detachable flange 15 to the outer surface with bolts or the like. The disk 14 ′ has a diameter larger than that of the inner circumference of the winding drum and is concentrically and integrally fixed to the fixed flange 14. The inner circumferential flange 17 of the winding cylinder and the disc 14 'are provided with notched grooves 18 and 19 which are open to the outer periphery at equal intervals in the circumferential direction, and the fixed horizontal shaft 21 is provided with the notched groove 1 described above.
It is fitted and fixed to every other one of 8 and 19. Since the inner circumference flange 17 of the winding cylinder has a smaller diameter than the disk 14 ', the fixed horizontal shaft 21 is fixed to the draft by this. In addition, the movable cross member 22 is fitted into the remaining four cut grooves 18 and 19,
It is pivotally attached to the disk 14 'by a pin 22a, and is rotatable in the radial direction with the pin 22a as a fulcrum, and its free end is the cut groove 1

The detachable collar 15 includes an inner collar 15c having a radial elongated hole 23,
It is composed of an annular pipe 15a for guiding the winding of a power transmission line, and its spokes 15b.

A center shaft 20 projecting outward from the fixed flange 15 is provided between the centers of the inner circumference flange 17 of the winding drum and the fixed flange 14, and the protruding portion from the fixed flange 15 is mounted on the bearing 2 on the support base.
While being supported by Nos. 4 and 24, a chain wheel 25 is attached to this, and the driving force from the hydraulic motor is transmitted by chain conduction.

As shown in the solid line and the chain line 22 'in FIGS. 14 and 15, the movable cross member 22 that acts as a winding drum rotates in the radial direction about the pin 22a as a fulcrum, so that the shaft of the winding device is rotated. It is necessary to firmly support the power transmission line so that it can face the winding force of the power transmission line while winding the power transmission line in a posture parallel to the core. As a means for this, it is necessary to insert the free end of the movable crosspiece 22 into a radial elongated hole 23 provided in the inner flange 15c of the detachable flange 15 and strongly press the radially outward end of the elongated hole. .
FIG. 15 is an explanatory view therefor, and a urging mechanism 26 for pressing the movable lateral joint 22 against the radially outward end of the radial elongated hole 23.

That is, a square screw shaft 29 is passed between the inner and outer bearings 27 and 28 of the short cylindrical portion 20a, and the portion of the square screw shaft protruding outward from the bearing 28 is a keyed shaft 29 '. A nut 16 'fitted on the attached shaft and screwed into the screw shaft in front of the keyed shaft secures the handle 16 to the detachable collar or the inner peripheral collar of the winding cylinder. The female screw cylinder 30 is engaged with the outer periphery of the square screw shaft 29, and the link mechanism 31 is attached to each of the four outer periphery of the female screw cylinder 30 and extends in the radial direction, that is, in all directions.
15, the link mechanism 31 pushes and pulls the push-pull rod 33 of the movable horizontal shaft which is slidably engaged with the guide tube 32 which penetrates the peripheral wall of the short cylindrical portion 20a in the radial direction.
The push-pull action moves the female screw cylinder 30 in the axial direction by the forward and reverse rotations of the handle 16, and pushes the push-pull rod 33 of the movable horizontal shaft outward in the radial direction by the link mechanism 31 to move the free end of the horizontal shaft. It is pressed against the radially outward end of the radial elongated hole 23 of the detachable collar to make the movable horizontal shaft parallel to the axis of the winding device,
On the contrary, the push-pull rod is pulled inward in the radial direction so that the free end of the horizontal rod contacts the radially inward end of the radial elongated hole, and the movable horizontal rod is drafted.

In this way, the four movable cross members are attached to the urging device 26.
Keep parallel to the axis of the winding device, the chain wheel 25 receives the rotational driving force of the hydraulic motor by the chain wheel 25, and the power transmission line is wound on the four movable horizontal shafts. Before removing W, the tail must be cut off. To this end, the front and rear clamps 8F and 8R that were open during winding are closed to fix the power transmission line W, and the cutter 7 is operated. FIG.

The restraining plate 8b has a reinforcing bone and a female screw 8e in the center thereof, and the female screw 8e is screw-engaged with a vertical screw shaft 8d standing from the receiving plate 8a. This vertical screw shaft is rotationally driven by a hydraulic motor 8c, whereby the holding plate 8 moves up and down, and when it moves downward, it fixes the power transmission line on the receiving plate 8a. In addition, 8f is a vertical guide rod, which prevents the pressing plate from rotating when the pressing plate 8b moves up and down by the rotation of the hydraulic motor. After fixing the power transmission line W by the front and rear clamps 8F and 8R in this manner, the power transmission line is bound before and after the cutting position, and then cut by the cutter 7 to prevent the twisted wires of the power transmission line from coming apart. Further, in order to prevent the power transmission line wound on the four movable shafts from being unwound, the winding bundle of the power transmission lines wound on the movable shaft is also bound.

When the power transmission line is cut by the cutter in this way, the movable blade 7b is returned and the clamps 8F, 8R before and after the cutter are cut.
The holding plate 8b is raised, and the four movable cauldrons 22 are made into a draft 22 'by an urging device, the detachable collar 15 is removed, and a winding bundle of the transmission line wound from the drafted fixed cauldron and the movable casket is removed.

Therefore, the width of the guide roller 14 on the roof of the driver's seat is set larger than the width at which the power transmission line is swung to the left and right. This allows a larger winding device to be used to remove and recover the transmission line.

In the overhead car of the embodiment shown in FIGS. 16 and 17, since the winding device 10 is provided on the front end of the chassis, the winding device can be used to wind the power transmission line. Since the lateral guide rollers 14 are provided on the roof of the driver's seat 13, a large winding device 10 'is installed in front of the driver's seat as described above, and a larger amount of the winding device 10' is fed by the winding device 10 '. You can also wind the wire.

However, when the power transmission line is wound by using only the winding device 10 'installed in front of the driver's seat, the guide roller 14 is provided on the driver's seat and is shown in FIG. The winding device on the undercarriage may be omitted as described above.

The large-scale winding device 10 'may be installed on the chassis 1'of another automobile as shown in FIG.
In this case, the hoisting device 11 for removing the winding bundle of the power transmission line wound on the winding device from the winding drum having a draft and installing it on the ground or on the truck is installed in another vehicle as shown in the figure. May be.

In this way, the winch 5 and its trailing-side feed device 6 advance the power transmission line forward, rotate the reels 10b and 10b 'of the winding devices 10 and 10' at a peripheral speed synchronized with the speed, and wear It is possible to wind up the transmission line with labor saving while cutting off the snow prevention ring.

Although the present invention has been described with reference to the illustrated embodiments, it goes without saying that the present invention can be variously changed and applied according to the implementation conditions without changing the gist thereof. For example, to increase efficiency by increasing the number of mechanical equipment for collection and removal on the base rather than one or two sets, or use an overhead car as a trailer that is pulled and moved by an automobile instead of a car with a driver's seat. , Easily thought of. In the case of a trailer, since there is no driver's seat, a turret may be set up instead of the driver's seat, and the guide rolls 14 and 14 may be provided on the turret.

According to the invention of claim 1, the inconvenient transportation of mechanical equipment and tools near the steel tower to the site, the movement and the arrangement and the removal work can be completed only by moving the vehicle body, and the troublesome snow accretion. For the first time, the individual work of pulling, winding, and cutting of the transmission line, including the work of removing the prevention ring, can all be done mechanically on the undercarriage of the overhead car. This will greatly reduce the labor of workers and improve the efficiency.

According to the second aspect of the present invention, a larger winding device 10 'is used without using the winding device 10 on the chassis.
Can be used to wind, remove, and collect a large amount of power lines.

Conventionally, it has been limited to relatively thin electric wires and hoses to take out a winding bundle after winding it with a winding device. The invention of claim 3 paved the way for the first time to extract a power transmission line with a thickness and rigidity that was not considered before from the winding device to form a winding bundle. Therefore, we developed a winding drum and a collar that can withstand the enormous winding pressure of the power transmission line.In addition, after winding is complete, you can easily remove the detachable collar on one side and place the winding drum in the draft to make it easier to pull out. did. With this winding device, it is possible to greatly reduce the labor and space required to make, store, and use a large amount of winding device for large-scale construction work such as replacing old and new power lines.
