[0020] Because in use, i.e., in the setting... Figure 2 In the process of the illustrated barrier 8, whether the traveling mechanism 3 moves or not depends on whether the power mechanism 5 is working, and whether the power mechanism 5 is working depends on the electrical controller 111. Furthermore, since the traveling mechanism 3 is located between the two tower poles (i.e., "high-voltage towers", hereinafter the same) on the steel strand 10 (… Figure 2 As shown, the overhead power transmission line support mobile device moves on a steel strand 10 located tens of meters above the ground. Therefore, according to professional knowledge, it can only be operated remotely by an operator located on the ground using a signal transmitter (commonly referred to in the industry as a "remote controller") to transmit a remote control signal to an electrical controller equipped with a signal receiver, thereby achieving the purpose of remotely operating the electrical controller. In addition, in order to ensure that the aforementioned signal receiver can receive the remote control signal emitted from the signal transmitter, it is a preferred solution to install a signal receiving antenna 13 electrically connected to the electrical controller 111 on the top of the electrical control box 1.

The motor 51 is driven by the gearbox 52, and the gearbox 52 and the motor 51 are fixed to the gearbox mounting bracket 53 by gearbox fixing screws 522.

The first upper roller I 312 is located in the aforementioned upper roller shaft support cavity 3111 and is rotatably disposed in the middle of the first upper roller shaft I 3121 via a bearing. The left and right ends of the first upper roller shaft I 3121 are respectively supported on the left and right side walls of the upper roller shaft support 311 and are each locked by a first upper roller shaft locking nut I 31211. The second upper roller II 313 is located in the upper roller shaft support cavity 3111 at a position corresponding to the rear side of the first upper roller I 312 and is also rotatably mounted in the middle of the second upper roller shaft II 3131 via bearings. The left and right ends of the second upper roller shaft II 3131 are respectively supported on the left and right side walls of the upper roller shaft support 311 and are each locked by a second upper roller shaft locking nut II 31311.

The right end is rotatably supported on the right bearing 31412 of the drive gear shaft, which is located on the right side wall of the upper roller shaft support 311 and extends to the right side of the right bearing 31412. The first driven gear I 315 is located in the cavity 3111 of the upper roller shaft support and is fixed to the right side of the first upper roller I 312 by the first driven gear fixing screw I 3151. The first driven gear I 315 meshes with the drive gear 314 at a position corresponding to the front of the drive gear 314. The second driven gear... Wheel II 316 is disposed within the upper roller shaft support cavity 3111 and is fixed to the right side of the aforementioned second upper roller II 313 by a second driven gear fixing screw II 3161. The second driven gear II 316 meshes with the driving gear 314 at a position corresponding to the rear of the driving gear 314. The driving gear shaft support connecting plate 317 is located on the left side of the upper roller shaft support 311, and a connecting plate arc groove 3171 is formed on the upper part of the driving gear shaft support connecting plate 317. A connecting plate positioning screw 31711 is disposed at a position corresponding to the connecting plate arc groove 3171, and the connecting plate positioning screw 31711 is fixed to the connecting plate positioning screw hole 3112 formed on the left side wall of the upper roller shaft support 311.The lower left side of the drive gear shaft support connecting plate 317 is centrally hinged to or unhinged from the upper part of the left wall plate 21 of the aforementioned traveling mechanism bracket; the driven wheel 42 is fixed to the right end of the aforementioned drive gear shaft 3141; the lower roller device 32 corresponds to the area below the first upper roller I 312 and the second upper roller II 313.
[0026] By illustration Figure 1 As can be seen from the left side wall of the upper roller shaft support 311, the aforementioned left bearing 31411 of the drive gear shaft is disposed in a bearing hole in which the connecting plate bearing hole 3173 formed on the drive gear shaft support connecting plate 317 and the aforementioned left bearing hole 3114 of the drive gear shaft both cooperate. Alternatively, it can be stated that half of the thickness of the left bearing 31411 of the drive gear shaft is located in the left bearing hole 3114 of the drive gear shaft, while the other half is located in the connecting plate bearing hole 3173.
[0027] When the aforementioned transmission belt 43 drives the driven wheel 42 to move, the driven wheel 42 drives the driving gear shaft 3141, and the rotation of the driving gear shaft 3141 drives the driving gear 314. The driving gear 314 simultaneously drives the first driven gear I 315 and the second driven gear II 316 meshing with it. Thus, the first driven gear I 315 drives the first upper roller I 312, and the second driven gear II 316 drives the second upper roller II 313. As a result, the first upper roller I 312 and the second upper roller II 313, which rotate in the same direction, travel (roll) on the steel strand 10.

[0030] When to make by Figure 2 When the steel strand 10 is introduced between the lower part of the first upper roller I 312 and the second upper roller II 313 and the lower roller device 32 (described below), the power construction workers on the tower first remove the pin 2121 to release the hinge between the lower part of the drive gear shaft support connecting plate 317 and the hinge bushing 3172 of the pair of bracket left wall plate hinge bushings 212. Then, the upper roller shaft support seat 311 is rotated upward by an angle with the upper roller shaft support seat hinge bushing 3113 above the upper roller shaft support seat hinge bushing 3113, i.e., with the right wall plate hinge bushing pin 2221 of the bracket as the rotation fulcrum, so that the steel strand 10 enters between the lower part of the first upper roller I 312 and the second upper roller II 313 and the lower roller 322 of the lower roller device 32 (mentioned below). Then, the pin 2121 is returned so that the connecting plate bushing 3172 is restored to the state of hinged with the aforementioned pair of bracket left wall plate hinge bushings 212.

At this time, the adjusting screw 442 also moves forward accordingly. After the position of the tensioner frame 443 and the tensioner 444 is adjusted, tighten the rear screw nut of the pair of screw nuts 4421 to lock it in place. The aforementioned adjustment work is performed in advance on the ground as a maintenance adjustment work when not in use.

Figure 2 (Note), and a net pole connection hole 62 is provided at the bottom. When connecting the connecting rod, the aforementioned connecting rope connection hole 61 can be referred to as the connecting rod hole.
[0037] Below, the applicant describes the barrier rod position signal acquisition mechanism 7 installed on the right wall of the electrical control box 1. This barrier rod position signal acquisition mechanism 7 includes a bearing mounting plate 71, a rotary encoder shaft clamping block 72, a slide rail 73, a rotary encoder mounting base 74, a rotary encoder 75, and a pair of barrier rod feet 76. The upper end of the bearing mounting plate 71 is fixed to the right wall of the electrical control box 1 via bearing mounting plate screws 711, and the lower end extends to the bottom of the electrical control box 1. The rotary encoder mounting base 74 is fixed to the bottom of the electrical control box 1 via rotary encoder mounting base screws 741. The rotary encoder 75 is electrically connected to the aforementioned electrical controller 111 via rotary encoder mounting screws 752 and is fixed to the rotary encoder mounting base 74. The middle part of the rotary encoder shaft 751 of the rotary encoder 75 is rotatably supported on the lower end of the bearing mounting plate 71 via a rotary encoder shaft support bearing 7511 installed on the bearing mounting plate 71. The right end of the rotary encoder shaft 751... The end extends to the right side of the rotary encoder shaft support bearing 7511. The upper part of the rotary encoder shaft clamping block 72 has a pair of clamping feet 721, and a rotary encoder shaft mating hole 7211 is formed between the pair of clamping feet 721. The rotary encoder shaft mating hole 7211 mates with the right end of the rotary encoder shaft 751 and is clamped by the pair of clamping feet 721. The lower part of the rotary encoder shaft clamping block 72 is fixed to the upward-facing side of the slide rail 73 by rotary encoder shaft clamping block fixing screws 722. A slide rail groove 731 is formed on the slide rail 73, extending from the front end to the rear end. The upper ends of the pair of baffle rod feet 76 are each connected to a nut block 7311 movably disposed in the slide rail groove 731 by slide rail connecting screws 761. The lower ends of the pair of baffle rod feet 76 extend downward in a cantilever state, and the space between the pair of baffle rod feet 76 forms a baffle rod insertion cavity 762. Figure 1 The image also shows a clamping screw 723, which clamps or releases a pair of clamps 721.
[0038] Please pay attention. Figure 2 And combined Figure 1 In actual use, the aforementioned barrier rod insertion cavity 762 corresponds to the... Figure 2The barrier pole 9 shown has a connecting rope 611 (or connecting rod, connecting wire, or other similar connector) connecting between the connecting rope connecting holes 61 of the barrier pole connecting frame 6 of the overhead power transmission line support network moving device structure system of the present invention, and a barrier pole 9 is connected between the barrier pole connecting holes 62 of the barrier pole connecting frame 6 of the overhead power transmission line support network moving device structure system of the present invention, on both the left and right sides. The barrier net 8 is fitted onto the barrier pole 9 at the position corresponding to the barrier pole 9 by a barrier net rope loop or barrier net rope ring. Below the barrier net 8 are the aforementioned railways, highways, elevated roads, residential areas, important special facilities, or other corresponding facilities. Therefore, during the stringing or laying of the line, if the conductor or ground wire falls, the barrier net 8 will protect it and will not endanger the ground facilities.
[0039] As described above by the applicant, in the state where the power mechanism 5 drives the transition transmission mechanism 4, and then the transition transmission mechanism 4 drives the walking mechanism 3 to enter operation, the walking mechanism 3 moves on the stranded wire 10 through the joint cooperation of the first upper roller I 312, the second upper roller II 313, and the lower roller 322. During the movement, it should be ensured that the two overhead power transmission line support network moving devices of the present invention move side by side on the steel stranded wire, that is, it is not allowed that one of them is faster or slower. Therefore, if either of them has an excessively fast or slow movement difference, the baffle rod 9 acts on the baffle rod position signal acquisition mechanism 7, which feeds back the signal to the electrical controller 111. The electrical controller 111 then issues a command to the motor 51 of the power mechanism 5 structure system to adjust the working speed of the motor 51. Now, let's take... Figure 2Taking the rightmost one of the two overhead power transmission line support net moving devices of the present invention as an example, if the right end of the net support rod 9 is in front and the left end is behind, then the entire net support rod 9 will tilt. The right end of the net support rod 9 will act within the net support rod insertion cavity 762, thereby driving the front net support rod foot of the pair of net support rod feet 76. The front net support rod foot drives the rotary encoder shaft clamp 72 through the slide rail 73. The rotary encoder shaft clamp 72 drives the rotary encoder shaft 751 to rotate clockwise by an angle, so that the rotary encoder 75 feeds back the collected signal to the electrical controller 111. The electrical controller 111 sends a command to the motor 51 to slow down the speed of the motor 51, so that the net support rod 9 no longer tilts, thus ensuring its overall pulling and unfolding effect on the net support 8. Conversely, taking the rightmost one as an example again, if the right end of the net support rod 9 is behind and the left end is in front, then the entire net support rod 9 will tilt in the opposite way to the above situation. The right end of the baffle rod 9 acts within the baffle rod insertion cavity 762, driving one of the rear baffle rod feet 76. This rear baffle rod foot, via the slide rail 73, drives the rotary encoder shaft clamp 72. The rotary encoder shaft clamp 72 then rotates the rotary encoder shaft 751 counterclockwise by an angle, causing the rotary encoder 75 to feed back the collected signal to the electrical controller 111. The electrical controller 111 then sends a command to the motor 51, increasing its speed and preventing the baffle rod 9 from tilting, thus ensuring its overall pulling and unfolding effect on the baffle 8. Figure 2 The correction method for the tilting of the retaining pole 9 by the overhead power transmission line support moving device of the present invention on the left side of the state shown is the same, and will not be described again.
[0040] exist Figure 2 Although only two pairs of the present invention devices and two retaining net poles 9 are shown in the figure, it is obviously not limited to this number. The number can be reasonably increased or decreased according to the ground facilities. For example, if the distance between two adjacent retaining net poles 9 is 15 meters and the width of the elevated road, highway, etc. below is 30 meters, then three pairs (one pair at the beginning, one pair at the end, and one pair in the middle) of the present invention devices are needed to work on three retaining net poles 9 (one pair at the beginning, one pair at the end, and one pair in the middle). If the residential area above the ground facilities is 150 meters, then eleven pairs of the present invention devices and eleven retaining net poles 9 are needed.
[0041] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above-mentioned technical effects column.
