DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0037] like Figure 1-10 The grounding wire device for remotely controlling the ground machine shown in the figure comprises a drive control box 1 and a grounding copper wire 11 arranged at the lower end of the drive control box 1, and comprises two sets of clamping arms 2 arranged on the drive control box 1 and hinged to each other, and a card interface 21 for accommodating the wire is arranged on the opposite sides of the two sets of clamping arms 2, and the clamping arms 2 and the grounding copper wire 11 are connected; a driving mechanism is arranged between the clamping arms 2 and the drive control box 1, and is used to drive the two sets of clamping arms 2 to clamp; a traction mechanism is arranged on the drive control box 1 and the clamping mechanism, and is used to pull the device to the wire position. The traditional wire grounding operation requires the staff to carry one end of the grounding copper wire 11 to climb up the pole tower, and The grounding copper wire 11 is connected to the conductor to complete the grounding of the conductor. This grounding work has high risks. The purpose of setting up this device is to enable the staff to operate directly on the ground, and bring the grounding copper wire 11 to a high altitude to connect with the conductor to complete the grounding, so as to reduce the operation risk. It mainly utilizes the connection between the clamping arm 2 and the grounding copper wire 11, and sets an insulating rope 43. The insulating rope 43 is overlapped on the conductor and rolled up. The device can be directly taken off the ground, and then the clamping arm 2 is controlled to clamp the conductor with remote control, so that the grounding copper wire 11 and the conductor are connected, and the grounding work of the conductor can be completed conveniently.

[0038] In one embodiment, the two groups of clamping arms 2 are hinged by a movable shaft 22, and a bearing frame 23 is provided on the movable shaft 22. The driving mechanism includes a driving motor 3 arranged in the driving control box 1, a threaded screw 31 at one end mounted on the driving motor 3 and rotatably connected to the bearing frame 23 at the other end, a screw sleeve 32 movable at an upper limit position on the threaded screw 31, and two groups of connecting rods 33 at one end hinged to the bottom of the clamping arm 2 and at the other end hinged to the screw sleeve 32; a remote control module for remotely controlling the driving motor 3 is provided inside the driving control box 1, which is also equipped with a corresponding remote control, which can remotely control the driving control box 1, and then control the rotation of the threaded screw 31 to control the clamping and opening of the clamping arm 2. The main control process is to drive the threaded screw 31 to rotate, thereby driving the screw sleeve 32 to move upward, so that the bottom of the clamping arm 2 is stretched to both sides by using the connecting rod 33, so that the screw sleeves 32 are relatively clamped, and when the screw sleeves 32 move downward, the opposite action is achieved, so that the card interface 21 is opened.

[0039] In one embodiment, the traction mechanism includes a lifting assembly for lifting the device and a pulling assembly for controlling the relative angle between the device and the conductor. The lifting assembly includes a hanging ring 4 rotatably arranged on a group of clamp arms 2, two groups of lifting ropes 41 fastened to the hanging ring 4, a support rod 42 with two ends respectively fastened to the two groups of lifting ropes 41 at one end away from the hanging ring 4, and an insulating rope 43 arranged on the support rod 42. The function of the insulating rope 43 is similar to the fixed pulley principle. By hanging the insulating rope 43 on the conductor, the conductor becomes a fixed pulley. At this time, the free end of the wound insulating rope 43 can pull the device upward to move it to the conductor position. The hanging ring 4 is arranged on one side of the clamp arm 2 to ensure that it will not block the clamping opening between the clamp arms 2, and when it is pulled to the conductor position, one group of clamp arms 2 will be on one side of the conductor. At this time, the conductor is just located at the clamping opening between the clamp arms 2, which is convenient for the subsequent clamping of the conductor by the clamp arms 2.

[0040] In one embodiment, the pulling assembly includes two groups of side extension rods 44 arranged on both sides of the drive control box 1 and two groups of control ropes 45 respectively arranged on the two groups of side extension rods 44. The setting of the control rope 45 allows the staff on the ground to control the angle of the device relative to the conductor by pulling the two groups of control ropes 45, so as to facilitate the control of the clamping arm 2 to accurately clamp the conductor.

[0041] In one embodiment, the clamp arm 2 is also provided with a guiding mechanism for guiding the wire into the card interface 21 when the clamp arm 2 clamps the wire; the guiding mechanism includes a wire lifting component that lifts the wire into the position of the card interface 21 when the wire excessively extends into the clamping gap between the two sets of clamp arms 2, and a guiding component that guides the wire into the card interface 21 when the wire is not fully extended into the card interface 21. Since the clamp arm 2 needs to ensure that the wire is exactly located in the card interface 21 during the clamping process, otherwise the clamping force of the wire will be insufficient, thereby easily resulting in the risk of disconnection of the conduction between the grounding copper wire 11 and the wire. Therefore, a wire lifting component and a guiding component are provided on the clamp arm 2 to ensure that the wire will not be clamped at the upper and lower sides of the card interface 21, resulting in the inability to completely close the clamp arms 2.

[0042] In one embodiment, movable grooves 5 located below the card interface 21 are provided on opposite sides of the two groups of clamping arms 2, and the wire lifting assembly includes a wire lifting plate 51 whose two ends slide in the movable grooves 5 and whose upper surfaces are curved surfaces convex upward, and movable rollers 52 rotatably arranged at both ends of the wire lifting plate 51; limiting slide grooves 53 for limiting the movement of the movable rollers 52 are correspondingly provided on both sides of the movable grooves 5; the inner side walls of the movable grooves 5 and the limiting slide grooves 53 on both sides gradually incline toward the relatively distant side from bottom to top, and when the wire is in the clamping mouth of the clamping arm 2 and is located at the lower side of the card interface 21, it will overlap on the wire lifting plate 51 at this time, and when the clamping arms 2 are relatively clamped, the movable rollers 52 on both sides of the wire lifting plate 51 will roll in the limiting slide grooves 53, and when the limiting slide grooves 53 gradually approach each other, squeeze the wire lifting plate 51 to move upward, thereby lifting the wire into the card interface 21, but when the clamping arm 2 is about to be completely closed, the wire is completely lifted to the card interface 21 at this time.

[0043] In one embodiment, a group of clamping arms 2 are provided with a mounting groove 6 on the upper side of the card interface 21, and the guiding assembly includes two groups of transmission rollers 61 rotatably arranged in the mounting groove 6 and a guiding belt 62 sleeved on the transmission rollers 61; one group of transmission rollers 61 is provided with a driving shaft 63 whose two ends are movably connected with the side walls of the mounting groove 6 respectively, one end of the driving shaft 63 is fixedly wound with a driving rope 64 and the other end is provided with a clockwork spring 65; a hanging rod 66 is provided on the wire lifting plate 51, and one end of the driving rope 64 away from the driving shaft 63 is fixedly wound on the hanging rod 66. When the wire is at the clamping mouth of the clamping arm 2 and is located When the card interface 21 is in the upper position, the clamping arm 2 clamps and drives the wire lifting plate 51 to move upward. When the wire lifting plate 51 moves upward, it pulls the driving rope 64 through the hanging rod 66, thereby causing the driving shaft 63 to rotate. After the driving shaft 63 rotates, it drives the guide belt 62 to rotate toward the card interface 21 side. Then, when the wire is attached to the guide belt 62, it can be pushed toward the card interface 21 under the action of the guide belt 62, and the corresponding clamping arm 2 will be subjected to the opposite force and gradually corrected, and then the staff will pull the control rope 45 on the ground to guide the wire into the card interface 21.

[0044] In one embodiment, the guide belt 62 protrudes from the outer surface of the clamping arm 2, and a receiving groove 7 for accommodating the guide belt 62 is correspondingly provided on a group of clamping arms 2 opposite to the guide belt 62, thereby facilitating the complete closure of the clamping arms 2; a guide rod 71 for changing the direction of the driving rope 64 is provided on the outer surface of the clamping arm 2 provided with the guide belt 62, thereby preventing the driving rope 64 from blocking the clamping position of the clamping arm 2; a receiving opening 72 for accommodating the hanging rod 66 is provided on the side wall of the movable groove 5 opposite to the hanging rod 66, thereby preventing the hanging rod 66 from being stuck between the clamping arms 2 and causing them to be unable to be completely closed.

[0045] The method for using the grounding wire device installed by remote control of the ground machine includes the following steps:

[0046] 1. Connect the drone to the free end of the insulating rope 43, and remotely control the drone to cross the wire so that the middle section of the insulating rope 43 is located on the upper side of the wire;

[0047] Second, control the drone to throw the free end of the insulating rope 43 to the ground so that the middle section of the insulating rope 43 overlaps the wire. At this time, the wire is equivalent to a fixed pulley;

[0048] 3. Reel the insulating rope 43 from the free end of the insulating rope 43, pull the device upward, and gradually bring it close to the wire. When it is close to the wire, make the upper end of the clamping arm 2 connected with the insulating rope 43 higher than the height of the wire to ensure that the wire is located between the clamping openings of the two sets of clamping arms 2;

[0049] Fourth, adjust the clamping openings of the two sets of clamping arms 2 to deviate toward the conductor by pulling the control rope 45, and try to keep the clamping openings facing upwards;

[0050] 5. The clamp arm 2 is driven by remote control to clamp the wire, and the control rope 45 is pulled to clamp the wire in the card interface 21. At this time, a channel is completed between the grounding copper wire 11 and the wire, and one end of the grounding copper wire 11 is grounded, thereby realizing the grounding of the wire, and then the line maintenance work can be carried out;

[0051] 6. After completing the line maintenance, the clamp arm 2 is remotely controlled to loosen the wire and gradually release the rolled insulating rope 43, the device is lowered to the ground, and the insulating rope 43 is removed from the wire to complete the use of the device.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
