Description

[Technical field]

[0001] This invention relates to a winding auxiliary device for cables and electric wires such as bypass cables, which assists an operator in manually rotating and winding a reel for winding a cable set on a winding machine. Note that the term "winding machine" as used herein includes a narrowly defined winding machine, a winding machine, a wire reeling table, a trolley, and the like. Furthermore, the term "cable" includes a narrowly defined wire body such as a cable or an electric wire. Furthermore, the term "reel" includes a narrowly defined reel and drum. [Background technology]

[0002] In the construction of power distribution lines, the work of paying out and winding the bypass cable during uninterruptible construction is carried out manually using a wire-out machine. There are no particular problems with the payout work, but the winding work when recovering the cable requires manually rotating the cable winding reel set on the wire-out machine, which places a heavy burden on the workers.

[0003] Therefore, devices have been developed that use a drive source such as a motor to rotate a reel that winds up such a cable or a drum.

[0004] The device in Patent Document 1 is configured such that a tire acting as a friction wheel protruding from a drive unit attached to a drum stand abuts against the flange of a winding cable drum set on the drum stand; by driving the drive unit, the tire rotates, and the rotation of the tire is transmitted to the flange of the cable drum by friction, thereby rotating the cable drum by power.

[0005] Moreover, the device in Patent Document 2 comprises a drum having a pair of end plates with insertion holes on both ends of a roughly cylindrical body, a shaft inserted into a drum shaft hole formed by the internal space in the body and the insertion holes, and drum stands arranged on both ends of the shaft, with the shaft and drum rotating together, and a driving machine that rotates the shaft, and a driven part for transmitting the driving force of the driving machine is formed on the shaft, and the rotation of the driving machine is transmitted to the driven part of the shaft via a belt, thereby rotating the drum which is integral with the shaft.

[0006] [Patent Document 1] Utility Model Registration No. 2501374 [Patent Document 2] JP 2003-104624 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0007] However, in the above-mentioned Patent Documents 1 and 2, the rotary drive source for the drum is permanently installed, and the drum rotates by constantly driving the rotary drive source during the cable winding work. Therefore, the manual power of the worker is not required, and the rotary drive source is attached to the drum stand from the beginning. It does not supplement the manual power of the worker.

[0008] In addition, the device in Patent Document 1 transmits rotation from the drive unit to the drum by having a friction wheel come into contact with the outer periphery of the drum flange. Because the drum is transported by rolling, the drum flange wears and deforms and is no longer a perfect circle, so there is a risk that the rotation of the drive unit will not be transmitted smoothly to the drum.

[0009] Moreover, in the device of Patent Document 2, a rotational force is transmitted from a rotational drive source to a driven portion of a shaft via a belt, which requires machining of the shaft.

[0010] Therefore, in order to solve the above-mentioned problems, the present invention aims to provide a cable winding auxiliary device that is provided with a rotational drive auxiliary device that assists the manual labor of an operator when winding a cable onto a reel, and that can be easily attached to conventionally used reel or drum winding machines and can be removed when not needed. [Means for solving the problem]

[0011] The invention of claim 1 is a cable winding auxiliary device attached to a winding machine that has a shaft passed through a reel, and supports both ends of the shaft with two support frames to lift the reel above the ground and support it rotatably, The winding assist device comprises: fixed length of the board One end of one side The boss of the first pulley is provided on The other end of the one side a motor is provided on the boss, the boss is fixed by penetrating the tubular outer periphery into a hole in a base plate, the first pulley is rotatably provided on the outer periphery of the boss, a rotating plate is fixed to the tip of a plurality of legs standing at intervals on one side of the first pulley in parallel with the first pulley, a through hole is provided in the rotating plate on an extension line of the through hole of the boss, a rod-shaped rotating claw is provided on the outer surface of the rotating plate at a position separated from the through hole, and a transmission means is provided for transmitting the rotation of the motor to the first pulley, The cable winding auxiliary device is configured so that a shaft between the reel of the wire-unwinding machine and one of the support frames is covered with the through hole of the boss of the base plate and the through hole of the rotating plate, the base plate is fixed to the support frame of the wire-unwinding machine via a rope or belt, the rotating claw of the rotating plate protrudes between adjacent spokes of the reel, the motor is rotated to rotate the first pulley, and the rotating claw presses against the spokes to rotate the reel.

[0012] In addition, the invention of claim 2 is a cable winding auxiliary device as described in claim 1, in which the motor is an in-wheel motor of a second pulley provided on the base, and the transmission means is a belt stretched between the first pulley and the second pulley.

[0013] The invention of claim 3 provides the cable winding auxiliary device of claim 1 or 2, further comprising a battery for driving the motor and a controller for controlling the operation of the motor.

[0014] The invention of claim 4 is a cable winding auxiliary device described in any of claims 1 to 3, in which a fixing fastener is provided on the base, and the rope or belt is passed through the fixing fastener and wound around the support frame to fix it. Effect of the Invention

[0015] According to the invention of claim 1, by attaching the cable winding auxiliary device to a wire unwinding machine, once the worker starts to turn the flange of the reel, the reel will rotate by the power of the motor and the cable can be wound up. Therefore, the worker had to use both hands to turn the reel, but there is no need to use force to turn the reel. Also, since the cable winding device of the invention can be easily attached to a conventional wire unwinding machine, when transporting the cable wound on the reel, the reel can be rolled while the main body of the cable winding auxiliary device is attached to the shaft, which is convenient. Of course, the main body of the cable winding auxiliary device can also be easily removed from the shaft when transporting.

[0016] According to the invention of claim 2, since the motor is an in-wheel motor, the cable winding auxiliary device can be made compact.

[0017] According to the invention of claim 3, since the motor is powered by a battery, there is no need to select a place to wind the cable, and the worker can turn and hold the reel with one hand and wind the cable in an orderly manner with the other hand, which reduces the burden on the worker. Also, the controller makes it easy to start and stop the motor and adjust the rotation speed.

[0018] In addition, according to the invention of claim 4, when fixing the cable winding auxiliary device to the support frame of the wire unwinding machine, it is only necessary to hook a rope or wire onto the fixing fastener provided on the base and fix it to the support frame, making it easy to fix it to the device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] (Embodiment Example 1) Before describing the cable winding auxiliary device A according to the first embodiment of the present invention, the cable unwinding machine B to which the cable winding auxiliary device A is attached will be described with reference to Figs.

[0021] As shown in Figure 7, the wire unwinding machine B consists of a reel 1 for winding the cable, a shaft 2 that passes through the center hole of the reel 1, and two support frames 3 attached to both ends of the shaft 2 inserted into the center hole of the reel 1, and the flanges on both sides of the reel 1 are provided with a number of spokes 4.

[0022] The reel 1 (not shown) with the cable wound around it is rolled to the installation site, and at the installation site of the wire-unwinding machine B, two support frames 3 are attached to both ends of the shaft 2, and then these support frames 3 are rotated using the principle of leverage to stand the support frames 3 with the reel 1 raised above the ground or floor, as shown in Figures 8 and 9. In this way, the wire-unwinding machine B is assembled.

[0023] The cable winding auxiliary device A of the present invention is attached to the shaft 2 between one side of the reel 1 and the supporting frame 3 facing the reel 1 in the cable unwinding machine B, as shown in Figs.

[0024] Next, the cable winding auxiliary device A will be described with reference to Figs.

[0025] A hole is provided at one end of a base plate 5 made of a fixed length of channel steel, and a cylindrical boss 6 is fitted into the hole so that the boss 6 is fixed in a state where it penetrates the base plate 5. A first pulley 7 is rotatably provided on the outer periphery of one side of the boss 6 protruding from the base plate 5.

[0026] A second pulley 8 incorporating an in-wheel motor is provided on one side surface of the other end of the base plate 5 to which the boss 6 is attached at one end. A V-belt 9 is hung between the first pulley 7 and second pulley 8, and rotation is transmitted by the V-belt 9.

[0027] Four legs 10 are provided at intervals on one side of the first pulley 7, and an elliptical rotating plate 11 is fixed to the tips of these legs 10, and the rotating plate 11 is provided in parallel to the first pulley 7. The rotating plate 11 is provided with a through hole 12 on an extension line of the through hole of the boss 6. Two rotating claws 13 are provided at both ends of the ellipse of the rotating plate 11, sandwiching the through hole 12 therebetween.

[0028] Further, an annular spacer 14 is provided between the base plate 5 and the first pulley 7 and on the outer periphery of the boss 6 outside the first pulley 7 , and the first pulley 7 is fixed to the boss 6 .

[0029] The second pulley 8 is rotatably supported by a support pillar 15 having one end fixed to the base plate 5. In order to stably support the second pulley 8, an auxiliary support pillar 16 is provided from the base plate 5 beside the second pulley 8, and a connecting plate 17 is provided between the tip of the auxiliary support pillar 16 and the tip of the support pillar 15.

[0030] A fixing hook 18 is provided on the end of the base plate 5 on the side of the second pulley 8. When one end of the base plate 5 is fixed to one of the support frames 3 of the wire drawing machine B, a belt or rope is wound around the fixing hook 18 and the support frame 3.

[0031] 6, the battery 19 and the driver 20 are stored in a bag 21, and power is supplied from the battery 19 to the driver 20 via a first cord 22, and power and a control signal are supplied from the driver 19 to the in-wheel motor of the second pulley 8 via a second cord 23. A connector 23a is provided in the middle of the second cord 23, and the second cord 23 can be freely disconnected by the connector 23a.

[0032] Furthermore, a third cord 24 is led out from the driver 20, and the third cord 24 is connected to a controller 25. The bag 21 is suspended from a support frame 3, and the controller 25 is also separately fixed to the support frame 3. Of course, the bag 21 may be placed on the ground.

[0033] To attach the cable winding auxiliary device A configured as described above to the cable unwinding machine B, one end of the shaft 2 inserted into the center hole of the reel 1 is fitted with the boss 6 of the base plate 5 as shown in Figure 7. At that time, the boss 6 is fitted onto the shaft 2 so that the rotary claws 13 protruding from the rotary plate 11 are placed between the adjacent spokes 4 of the reel 1.

[0034] Thereafter, the two support frames 3 are attached to one end of the shaft 2 beside the boss 6 and to the shaft 2 beside the reel 1 that is not covered by the boss 6. Then, each support frame 3 is raised to raise the reel 1 above the floor or ground, and the fixing hooks 18 of the board 5 are brought close to the support frames 3, and a belt 26 is wound around the fixing hooks 18 and the support frames 3 to fix one end of the board 5 to the support frames 3. The bag 20 is also hung from the support frames 3, and the controller 24 is also fixed to the support frames 3.

[0035] Then, one end of a cable (not shown) is fixed to the reel 1, and the worker turns on the switch of the controller 25, and further turns the knob of the controller 25 to control the rotation speed of the in-wheel motor. This causes the second pulley 8 and the first pulley 7 to rotate, which in turn rotates the rotating claw 13 of the rotating plate 11 of the first pulley 7, pushing the spokes 4 of the reel 1 and causing the reel 1 to rotate around the shaft 2. The maximum rotation speed is set to be equivalent to the rotation speed of current manual winding work.

[0036] This allows reel 1 to wind up the cable. This in-wheel motor has a function that automatically stops rotation when a certain load is applied, so in case of an emergency stop while winding up the cable, it is possible to stop the rotation by grabbing the reel flange or by pulling the cable. In short, the motor will stop if a certain load is applied. Also, if the motor is turned off while the cable winding auxiliary device is attached, the cable can be paid out.

[0037] In the above-mentioned embodiment 1, the cable winding auxiliary device A is attached to the reel 1, but it may be attached to a drum. Also, in the above-mentioned embodiment 1, an in-wheel motor is used as the driving source, but this is not limiting and a normal motor may be used. Also, the rotation of the motor is transmitted to the first pulley 7 by a V-belt 9, but the rotation may be transmitted by gears or the like.

[0038] In addition, in the above-mentioned first embodiment, the fixing hook 18 is provided at one end of the substrate 5, but this fixing hook 18 is not an essential requirement of the present invention. One end of the substrate 5 and the wire-unwinding machine B may be fixed by wrapping a rope, belt, binding wire, etc. around them. Therefore, the term "rope or belt" includes bands, binding wires, etc.

[0039] Further, in the first embodiment, the power source for the in-wheel motor is battery 19, but the power source for the motor may be supplied from a commercial power source. [Explanation of symbols]
