Abstract

To provide a cable winding vehicle capable of efficiently and safely recovering a cable to be removed. [Solution] The cable winding vehicle is equipped with a capstan 4, a reel winder 5, first and second drive devices 7 and 8, cable release devices 10-1 and 10-2, and a control device 6 mounted on a self-propelled running body 3 that moves on crawlers 2. The capstan and reel winder are rotated by the first and second drive devices, respectively. The control device controls the running body, the first and second drive devices, and the cable release device, and is operated by a remote control device. The reel of the reel winder has a truncated cone-shaped drum, a fixed flange on the large-diameter side of the drum with a cable release device attached, and a detachable flange on the small-diameter side. When the cable wound onto the reel reaches a predetermined length, the cable is bundled with a bundling material and the detachable flange is removed. The cable release device is then pressed from the large-diameter end of the drum toward the small-diameter end, causing the bundle of cables to fall off and be removed.

Description

[Technical Field]

[0001] This invention relates to a cable winding vehicle used for removing and recovering cables during cable replacement work on power transmission lines, extra-high voltage transmission lines, etc. [Background technology]

[0002] In recent years, social infrastructure constructed during the period of rapid economic growth has deteriorated over time, resulting in problems such as reduced functionality, increased risk of accidents, and the impact on daily life. Power transmission lines and extra-high voltage power lines are no exception, and existing lines are becoming increasingly aging and needing replacement work, with this number expected to increase in the future.

[0003] When replacing a power transmission line, it is necessary to remove and recover the existing power transmission line. For example, Patent Document 1 discloses a cable work vehicle that rotatably holds a cable drum that can take up cable on the loading platform of a mobile vehicle (truck), and controls the rotation of the cable drum based on commands from a remote control device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2024-172070 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with a cable work vehicle configured as described above, when a predetermined amount of cable is wound onto the cable drum, it is necessary to either remove the cable from the cable drum supported by the rotating shaft and arm, or replace the cable drum and continue work.

[0006] For this reason, when removing and recovering long cables, the work becomes complicated and safety must be taken into consideration. Although there are devices that cut and recover cables on-site, this not only increases the labor required for cutting but also the cost of post-processing, making it undesirable from the perspective of effective resource utilization.

[0007] Furthermore, roads and large spaces are required for trucks to travel, which places restrictions on the work site.

[0008] Therefore, the present invention was created in consideration of the various circumstances that existed in the past as described above, and its object is to provide a cable winding car that can efficiently and safely recover the cable to be removed. [Means for solving the problem]

[0009] The cable winding vehicle according to the present invention comprises a self-propelled vehicle that moves on crawlers, a capstan that is installed on the vehicle and winds up the cable, a first drive device that rotates and drives the capstan, a reel winder that is installed on the vehicle and winds up and recovers the cable that has been wound around the capstan, a second drive device that rotates and drives the reel winder, and a cable detachment device that detaches the recovered cable bundle when the cable wound around the reel of the reel winder reaches a predetermined length, and the vehicle, the first drive device, the second drive device, and the cable detachment device. The reel of the reel winder comprises a truncated cone-shaped drum, a fixed flange attached to the large-diameter end face of the drum and having the cable release device attached thereto, and a detachable flange attached to the small-diameter end face of the drum; when the cable wound around the reel of the reel winder reaches a predetermined length, the cable is bundled with a binding material and the detachable flange is removed, and the cable release device is pressed from the large-diameter end of the drum toward the small-diameter end to release and remove the cable bundle, thereby solving the above-mentioned problem.

[0010] With this configuration, when the cable wound around the reel winder reaches a predetermined length, the reel's detachable flange can be released and the cable bundle can be pressed by the cable detachment device to drop it off the reel and separated, making it easy to recover the cable bundle.

[0011] Furthermore, by mounting the capstan and reel winder on a self-propelled vehicle, cable winding work can be done in narrow spaces, allowing for free movement within the work site.Moreover, because it moves on crawlers, the track shoes can rotate while maintaining their shape even on uneven ground, making it highly capable of traveling on rough roads and uneven ground, and it can also travel on soft ground.The larger contact area than wheels provides strong traction and allows for smooth running.

[0012] Furthermore, the above-mentioned problem is also solved by further providing a traverse mechanism or a guide roller interposed between the capstan and the reel of the reel winder.

[0013] With this configuration, the cable wound by the capstan can be wound evenly and accurately onto the reel of the reel winder.

[0014] In addition, the above-mentioned problem is also solved by further providing a plurality of anti-slip members arranged at predetermined intervals along the rotation axis direction on the side surface of the drum.

[0015] With this configuration, the plurality of anti-slip members can suppress slippage that occurs when the cable is wound around the reel drum.

[0016] Furthermore, the detachable flange is detachably fixed to the end face of the small diameter side of the drum with a screw, thereby solving the above-mentioned problem.

[0017] With this configuration, the detachable flange can be easily attached and detached from the reel.

[0018] In addition, the cable removal device also solves the above-mentioned problem by hydraulically extending a piston inside a cylinder, pushing the cable bundle from the large-diameter end face of the drum toward the small-diameter end face, causing it to fall off.

[0019] With this configuration, the bundle of cables wound around the reel can be easily removed. Furthermore, if the cable removal device is controlled by a remote control device, complicated work can be simplified and safety can be improved. [Effects of the Invention]

[0020] The cable winding vehicle of the present invention allows for efficient and safe recovery of removed electric wires. [Brief explanation of the drawings]

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0023] Figure 1 is a perspective view of a cable winding vehicle according to an embodiment of the present invention. This cable winding vehicle is used, for example, in the re-wire work of power transmission lines and extra-high voltage power lines. It is a self-propelled crawler vehicle that can move freely within the construction site and is equipped with a composite hydraulic winch, allowing it to retrieve removed power cables by remote control.

[0024] Here, the removal and recovery of power lines and extra-high voltage power lines (referred to as electric wires) will be used as an example for explanation, but the same can be applied to various other cables.

[0025] That is, the cable winding vehicle 1 is configured such that a capstan 4, a reel winder 5, a control device 6, etc. are installed on a self-propelled device (self-propelled traveling body) 3 that moves on a crawler 2.

[0026] The self-propelled device 3 is driven by, for example, a diesel engine, and is capable of moving freely with a capstan 4 and a reel winder 5 mounted thereon under the control of a control device 6. In this example, the diesel engine has a displacement of 3,059 cc and a rated output of 60.3 kW.

[0027] The capstan 4 is a cylindrical part for gripping and winding up electric wires or cables. The capstan 4 is driven to rotate by an electric winch unit (first drive device) 7. In this example, the maximum tension of the capstan 4 is 20 KN (2000 kgf), the winding speed is 0 to 40 m / min, and the capstan diameter is 1000 mm.

[0028] The reel winder 5 winds and recovers electric wires and cables, and is driven to rotate by an electric drive mechanism (second drive device) 8. The reel winder 5 is attached to the self-propelled device 3 in a foldable manner via an arm 9, and by folding the arm 9, the reel winder 5 extends forward from above the self-propelled device 3.

[0029] The dimensions of the reel 5a are, for example, an outer diameter of 1100 mm, an inner diameter of 526 mm, and an overall width of 400 mm. The maximum tension of the innermost layer of the reel winder 5 is 3.5 kN (350 kgf), the maximum tension of the outermost layer is 0.75 kN (75 kgf), and the amount of winding of the electric wire is 160 S × 1000 m.

[0030] The reel winder 5 is provided with a pair of hydraulic cable detachment devices (push-out jacks) 10-1, 10-2 that detach the bundle of electric wires (cable bundle) from the reel 5a when the electric wires wound around the reel 5a reach a predetermined length. Each of the hydraulic cable detachment devices 10-1, 10-2 uses hydraulic pressure in a cylinder to move a piston, pushing out the bundle of electric wires wound around the reel 5a and causing it to drop.

[0031] The control device 6 controls the overall operation of the cable winding vehicle 1, including the movement of the self-propelled device 3, the diesel engine, the winch unit 7 of the capstan 4, the drive mechanism 8, and the hydraulic cable release devices 10-1 and 10-2. The control device 6 is equipped with a detachable, wired remote control operation panel unit (remote control device), and is configured so that an operator can hold the remote control operation panel unit and operate it from a distance from the cable winding vehicle 1.

[0032] Although not shown in the figure, the remote control operation panel is equipped with an operation lever (electric joystick operation lever), tension meter, speed meter, length meter, etc., so that not only can the cable winding cart 1 be moved, but work can also be carried out while checking the winding status of the electric wires and cables being collected.

[0033] Next, the winding operation of the removed electric wire will be explained in detail with reference to Figs. 2 to 4. Fig. 2 is a plan view for explaining the winding of the guide cable and the electric wire on the capstan. Fig. 3 is a perspective view for explaining the winding operation by extracting the capstan 4 and the reel winder 5 of Fig. 1. Fig. 4 is a front view of the capstan 4 and the reel winder 5 of Fig. 3 as seen from the front of the cable winding wheel 1.

[0034] First, a guide cable 13 is attached to one end of the electric wire 12 to be removed, and the guide cable 13 is wound directly around the capstan 4 as shown in FIG. 2(a).

[0035] Next, as shown in Figure 2(b), the guide cable is wound around the capstan 4 several times, and when it has been wound the required number of times, the end of the guide cable 13 is attached to the reel 5a of the reel winder 5 via the traverse mechanism 11 as shown in Figure 2(c) (see Figure 3(a)).

[0036] Thereafter, as the capstan 4 rotates, the guide cable 13 is wound up, and when it reaches the end of the guide cable 13, the wire 13 to be removed is wound around the capstan 4 as shown in Figures 2(d) and 2(e). Then, as shown in FIG. 2(f), the electric wire 12 is finally wound around the capstan 4 a predetermined number of times, and thereafter the electric wire 12 is wound onto the reel 5a of the reel winder 5 (see FIG. 3(b)).

[0037] When winding the electric wire 12 onto the reel 5a, the traverse mechanism 11 (or guide roller) moves back and forth repeatedly within the width of the reel as shown by the arrows, as shown in Figure 4. This mechanism 11 prevents the electric wire or cable from being wound unevenly, and allows the electric wire or cable to be wound evenly onto the reel 5a.

[0038] When the electric wire 12 wound around the reel winder 5 reaches a predetermined length, the hydraulic cable release devices 10-1 and 10-2 cause the bundle of electric wires to drop off from the reel 5a and separate.

[0039] FIG. 5 is a perspective view of the reel 5a of the reel winder 5. The reel 5a has a truncated cone-shaped reel body (drum) 14a, and a pair of opposing flanges 14b, 14c provided on both end surfaces. Each of the pair of flanges 14b, 14c is composed of an annular body and support members arranged radially in the diameter direction of the annular body. A fixed flange 14b is provided on the large-diameter end surface of the drum 14a, and a detachable flange 14c is provided on the small-diameter end surface.

[0040] Hydraulic cable release devices 10-1 and 10-2 are installed on fixed flange 14b. Hydraulic cable release devices 10-1 and 10-2 are configured so that pistons 10-1b and 10-2b in cylinders 10-1a and 10-2a, respectively, protrude by hydraulic pressure and press the bundle of electric wires from the large-diameter end face of drum 14a toward the small-diameter end face, thereby releasing and separating the bundle of electric wires.

[0041] The detachable flange 14c has a disk-shaped plate member 14d attached to the center of the small diameter side of the drum 14a, and is detachably attached to the drum 14a via the plate member 14d with hand-tightened screws (screws) 15-1 to 15-4.

[0042] Furthermore, a plurality of anti-slip members 14e, 14e, ... are arranged at predetermined intervals along the rotation axis direction on the side surface of the drum 14a to prevent the wound electric wires or cables from slipping. The anti-slip members 14e, 14e, ... are made of, for example, metal rods or metal pipes and are welded to the side surface of the drum 14a.

[0043] Next, the process of removing the electric wire bundle 12A wound around the reel winder 5 will be described in detail with reference to Fig. 6 and Fig. 7A to Fig. 7F. Fig. 6 is a perspective view showing a state in which the arm 9 of the reel winder 5 in the cable winding wheel 1 of Fig. 1 is lowered. Also, Fig. 7A to Fig. 7F are perspective views sequentially showing the process of removing the electric wire bundle 12A wound around the reel 5a.

[0044] First, when the amount of wire 12 wound around the reel winder 5 reaches a predetermined amount, the arm 9 of the reel winder 5 on the cable winding car 1 is tilted by remote control using the remote control operation panel, as shown in Figure 6, and the reel winder 5 is moved so that it protrudes forward of the self-propelled device 3.

[0045] Next, as shown in Fig. 7A, the electric wires 12 wound around the reel winder 5 are cut and bound with binding materials (binding strings, binding ropes, binding bands, binding cables, etc.) 16-1 to 16-4. Subsequently, as shown in Fig. 7B, the hand-tightened screws 15-1 to 15-4 are removed from the plate material 14d. Then, as shown by the arrow in Fig. 7C, the detachable flange 14c is removed from the drum 14a. The plate material 14d is fixed to the detachable flange 14c.

[0046] In this state, the hydraulic pressure in the cylinders 10-1a and 10-2a of the hydraulic cable release devices 10-1 and 10-2 is used to protrude the pistons 10-1b and 10-2b in the remote control operation panel as shown by the arrows in FIG. 7D, and the pistons are pressed from the large-diameter end face of the drum 14a toward the small-diameter end face, thereby pushing out the bundle of electric wires 12A wound around the reel 5a.

[0047] Fig. 7E shows a state in which the electric wire bundle 12A has been removed. After that, the detachable flange 14c and the plate material 14d are attached to the drum 14a with the hand-tightened screws 15-1 to 15-4, and an empty reel 5a is formed as shown in Fig. 7F, and the work of removing the electric wires 12 can be started again.

[0048] This process of removing and recovering the electric wire 12 is repeated.

[0049] As described above, the cable winding vehicle of this invention makes it possible to safely retrieve removed electric wires at construction sites by remote control, which is not only effective in resource recovery but also contributes to improving work efficiency and reducing work-related accidents.

[0050] That is, the following effects can be obtained.

[0051] By installing the capstan 4 and reel winder 5 on the self-propelled device 3, the on-site burden of equipment operation can be reduced, and the temporary leased land area for equipment placement can be reduced, making it possible to wind up electric wires and cables in narrow areas.In addition, costs can be reduced because there is no need to use special construction methods (extending wires to adjacent spans, etc.).

[0052] In addition, since the equipment can be moved by itself, there is no need to arrange for a crane truck or to require the space required for it when carrying it in or out.Moreover, many highly dangerous operations, such as movement by the self-propelled device 3, operation of the capstan 4, operation of the reel winder 5, and operation of the hydraulic cable release devices 10-1 and 10-2, can be performed from a distance using the remote control operation panel, allowing for safe work.

[0053] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0054] For example, in the above-described embodiment, the case where the remote control is remotely controlled by wire using a remote control operation panel unit (remote control device) has been described as an example, but it is of course also possible to remotely control by wireless. Also, it is possible to configure the device to be controlled by a mobile information terminal, a smartphone, or the like, instead of a dedicated remote control operation panel unit.

[0055] Furthermore, although the example has been described in which the self-propelled device is driven by an engine and the capstan and reel winder are each driven to rotate individually by an electric drive unit, the present invention is not limited to this combination. Either or both of the capstan and the reel winder can be driven by an engine, and the self-propelled device can also be configured to be electrically driven.

[0056] In addition, a camera may be installed to photograph the surrounding environment, the capstan, and the reel winder, and a monitor may be provided on the remote control operation panel to monitor the surrounding environment and the state of the cable being collected. In this way, work can be performed while monitoring the surrounding conditions and the operating status of the cable winding cart, thereby further improving safety. [Industrial Applicability]

[0057] The cable winding vehicle of the present invention can be used, for example, in the re-laying of power transmission lines, and is industrially useful in terms of both on-site work safety and effective use of resources. [Explanation of symbols]
