In addition, the terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour. In addition, the terms "first", "second", etc. are only used to distinguish one element from another, and do not have order and importance.

[0032] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0033] In the related art, manual work is used to hang the ground wire, which has the disadvantages of great difficulty, low efficiency and high risk.

[0034] In view of this, if Figures 1 to 4As shown, the present disclosure provides a ground wire hanging device, the structure of which includes a base 100, a telescopic mechanism 200 and a wire clamping mechanism 300. The telescopic mechanism 200 is fixed to the base 100 at one end in the telescopic direction, and the wire clamping mechanism 300 includes a support column 310, a first clamping arm 320, a second clamping arm 330 and a clamping arm driving mechanism 340, wherein the first clamping arm 320 and the second clamping arm 330 are both conductive metal parts, and one end of the first clamping arm 320 and one end of the second clamping arm 330 can be rotatably connected to the support column 310, and the support column 310 is fixed to the other end of the telescopic mechanism 200 in the telescopic direction; the clamping arm driving mechanism 340 is arranged on the support column 310 and connected to the first clamping arm 320 and the second clamping arm 330, and the clamping arm driving mechanism 340 can drive the other end of the first clamping arm 320 and the other end of the second clamping arm 330 to move toward or away from each other.

[0035] It can be understood that the telescopic mechanism 200 is fixed on the base 100 at one end in the telescopic direction, and the other end of the telescopic mechanism 200 in the telescopic direction and the wire clamping mechanism 300 fixed on the end can be extended and moved in a direction away from the base 100, or retracted and moved in a direction close to the base 100 under the telescopic function of the telescopic mechanism 200. The clamping arm driving mechanism 340 in the wire clamping mechanism 300 drives the first clamping arm 320 and the second clamping arm 330 to move toward each other, so that the first clamping arm 320 and the second clamping arm 330 can clamp the wire of the ground wire 400 to be hung. The clamping arm driving mechanism 340 drives the first clamping arm 320 and the second clamping arm 330 to move away from each other, so that the first clamping arm 320 and the second clamping arm 330 can be opened to release the clamping of the wire of the ground wire 400 to be hung. The first clamping arm 320 and the second clamping arm 330 are configured as conductive metal parts. After clamping the wire, the first clamping arm 320 and the second clamping arm 330 can be electrically connected to the wire.

[0036] Through the above-mentioned ground wire hanging device, when it is necessary to hang the ground wire 400, the base 100 can be fixed on the ground, and the ground wire 400 can be connected to the first clamping arm 320 and / or the second clamping arm 330. Then, the telescopic mechanism 200 is extended to drive the clamping mechanism 300 to rise, move toward the wire direction of the ground wire 400 to be hung, and the first clamping arm 320 and the second clamping arm 330 of the clamping mechanism 300 clamp the wire inlet, so as to realize the electrical connection between the wire and the ground wire 400, and realize the ground wire hanging operation. Thus, the defects of the operator manually hanging the ground wire, such as the difficulty of operation, low operation efficiency and high danger, are solved.

[0037] It should be pointed out that in the above-mentioned ground wire hanging device, the telescopic mechanism 200 can be selected as an insulating telescopic mechanism to prevent the telescopic mechanism 200 from being conductive. Specifically, the telescopic mechanism 200 can be made of insulating material at the other end in its telescopic direction (i.e., the end where the telescopic mechanism 200 is connected to the wire clamping mechanism 300) or an insulating layer can be provided on the surface.

[0038] Regarding the specific structure of the first clamping arm 320 and the second clamping arm 330 in the wire clamping mechanism 300, in some optional embodiments, the first clamping arm 320 has a first connecting portion 321 and a first guiding portion 322 connected to each other, and the first connecting portion 321 is rotatably connected to the support column 310, and the second clamping arm 330 has a second connecting portion 331 and a second guiding portion 332 connected to each other, and the second connecting portion 331 is rotatably connected to the support column 310, and the first guide portion 322 and the second guide portion 332 constitute a V-shaped structure that can guide the wire.

[0039] By setting the first guide part 322 of the first clamping arm 320 and the second guide part 332 of the second clamping arm 330 to be a V-shaped structure capable of guiding the wire, when the ground wire 400 is hung, when the clamping mechanism 300 moves toward the wire under the drive of the telescopic mechanism 200, the wire will move along the surface of the first guide part 322 and / or the second guide part 332 under the guidance of the V-shaped structure, so that the first guide part 322 and the second guide part 332 are automatically opened and enter between the first connecting part 321 and the second connecting part 331, and then the wire is clamped by the first connecting part 321 and the second connecting part 331 moving toward each other. In this way, the V-shaped structure realizes the guidance and automatic clamping of the wire, thereby reducing the requirements for the installation accuracy of the ground wire hanging device.

[0040] It can be understood that the aforementioned guiding of the wire refers to guiding the wire from the outside of the wire clamping mechanism 300 to the first connecting portion 321 and the second connecting portion 331. Therefore, the opening direction of the V-shaped structure is toward the direction away from the support column 310, and the closing direction of the V-shaped structure is toward the direction close to the support column 310. When the first clamping arm 320 and the second clamping arm 330 are closed, the first clamping arm 320 and the second clamping arm 330 enclose a generally heart-shaped structure.

[0041] The present disclosure provides a specific implementation of the V-shaped structure, such as Figure 1 As shown, a first inclined surface 323 is provided at the end of the first guide portion 322 away from the first connecting portion 321, and a second inclined surface 333 is provided at the end of the second guide portion 332 away from the second connecting portion 331. The first inclined surface 323 and the second inclined surface 333 constitute a V-shaped structure capable of guiding the wire.

[0042] Since the first inclined surface 323 is located on the side of the first guide portion 322 away from the first connecting portion 321, and the second inclined surface 333 is located on the side of the second guide portion 332 away from the second connecting portion 331, the first inclined surface 323 is located on the outer side of the first clamping arm 320, and the second inclined surface 333 is located on the outer side of the second clamping arm 330. When the wire clamping mechanism 300 moves toward the direction of the wire, the first inclined surface 323 and the second inclined surface 333 will directly contact the wire, thereby guiding the wire through the V-shaped structure formed by the first inclined surface 323 and the second inclined surface 333.

[0043] Regarding the specific structure of the support column 310 , in some optional embodiments, the support column 310 includes an insulating portion 311 and a conductive portion 312 connected to each other, the first clamp arm 320 and the second clamp arm 330 are connected to the conductive portion 312 , and the insulating portion 311 is connected to the telescopic rod 210 .

[0044] By connecting the first clamp arm 320 and the second clamp arm 330 to the conductive portion 312 of the support column 310, the first clamp arm 320, the second clamp arm 330 and the conductive portion 312 can all transmit current, so that after clamping the wire, the ground wire 400 can be connected to any of the first clamp arm 320, the second clamp arm 330 and the conductive portion 312. In addition, by connecting the insulating portion 311 of the support column 310 to the telescopic mechanism 200, current is prevented from flowing to the telescopic mechanism 200 and the base 100.

[0045] The connection method between the conductive part 312 and the insulating part 311 includes, but is not limited to, bonding, threaded connection, snap connection, etc.

[0046] In order to facilitate operators to distinguish the conductive part 312 from the insulating part 311 and reduce the weight of the support column 310, in some optional embodiments, the diameter of the conductive part 312 is smaller than the diameter of the insulating part 311, and the length of the conductive part 312 is smaller than the length of the insulating part 311. The conductive part 312 can be made of conductive metal, and the insulating part 311 can be made of insulating rubber or plastic.

[0047] In order to conveniently connect the ground wire 400 to the wire clamping mechanism 300 , in some optional embodiments, a ground wire ring 350 is connected to the conductive portion 312 . The ground wire ring 350 is a metal part and is used to connect the ground wire 400 .

[0048] For the above-mentioned clamping arm driving mechanism 340, in some optional embodiments, the clamping arm driving mechanism 340 includes a first elastic member 341 and a second elastic member 342, the first elastic member 341 connects the first clamping arm 320 and the support column 310; the second elastic member 342 connects the second clamping arm 330 and the support column 310, and the first elastic member 341 and the second elastic member 342 are configured to be able to drive the first clamping arm 320 and the second clamping arm 330 to move toward each other under the action of elastic force.

[0049] The first elastic member 341 and the second elastic member 342 are provided so that the first clamping arm 320 and the second clamping arm 330 can be kept in a clamping posture without being affected by other external forces. Therefore, after the wire enters the first clamping arm 320 and the second clamping arm 330, the first elastic member 341 can drive the first clamping arm 320 and the second elastic member 342 can drive the second clamping arm 330 to automatically clamp the wire.

[0050] Regarding the specific structure of the first elastic member 341 and the second elastic member 342, in some optional embodiments, the first elastic member 341 and the second elastic member 342 are torsion springs. In some other optional embodiments, the first elastic member 341 and the second elastic member 342 can also be elastic members such as spring sheets and compression springs.

[0051] In some optional embodiments, the clamping arm driving mechanism 340 also includes a double-headed motor 343, a first cable 344 and a second cable 345. The double-headed motor 343 is installed on the support column 310. The double-headed motor 343 has a first rotating shaft portion and a second rotating shaft portion that rotate synchronously. The two ends of the first cable 344 are respectively connected to the first rotating shaft portion and the first clamping arm 320, and the two ends of the second cable 345 are respectively connected to the second rotating shaft portion and the second clamping arm 330. When the double-headed motor 343 rotates, the first cable 344 and the second cable 345 are wound or released.

[0052] When it is necessary to give up clamping the wire, the first cable 344 and the second cable 345 are wound simultaneously by the double-headed motor 343, so that the first clamp arm 320 and the second clamp arm 330 are pulled apart by the first cable 344 and the second cable 345, and the retraction action of the telescopic mechanism 200 is coordinated to realize the function of releasing the clamping of the wire. After releasing the clamping of the wire, the first cable 344 and the second cable 345 can be released by controlling the double-headed motor 343 to rotate in the opposite direction, so that the first clamp arm 320 moves toward each other under the action of the first elastic member 341 and the second clamp arm 330 moves toward each other under the action of the second elastic member 342.

[0053] It should be noted that when the support column 310 includes an insulating portion 311 and a conductive portion 312 , the double-headed motor 343 can be disposed on the insulating portion 311 .

[0054] Regarding the specific structure of the telescopic mechanism 200, in some optional embodiments, the telescopic mechanism 200 includes a telescopic rod 210, a driving motor 220, a gear 230 and a rack 240. The telescopic rod 210 is slidably connected to the base 100, and the rack 240 is arranged on the telescopic rod 210. The length direction of the rack 240 is parallel to the length direction of the telescopic rod 210. The gear 230 is fixed to the driving end of the driving motor 220 and meshes with the rack 240.

[0055] When the driving motor 220 rotates, the telescopic rod 210 can be moved relative to the base 100 through the cooperation between the rack 240 and the gear 230, thereby realizing the telescopic function.

[0056] In some optional embodiments, a slide groove is provided on the top of the base 100, a portion of the telescopic rod 210 and a portion of the rack 240 are both located in the slide groove, and a connecting groove is provided on the side wall of the base 100, and the connecting groove is connected to the slide groove. The drive motor 220 is fixed to the side wall of the base 100, and the rotating shaft of the drive motor 220 and the gear 230 fixed on the rotating shaft are inserted into the connecting groove, and the gear 230 and the rack 240 are meshed inside the base 100. In this way, the drive motor 220 drives the telescopic rod 210 to move.

[0057] In some optional embodiments, a battery 500 is disposed in the base 100 , and the battery 500 is used to supply power to the telescopic mechanism 200 and the wire clamping mechanism 300 .

[0058] The storage battery 500 supplies power to the telescopic mechanism 200 and the wire clamping mechanism 300, which can make the entire ground wire hanging device more convenient to carry and use.

[0059] It should be noted that the battery 500 is electrically connected to the drive motor 220 through a wire when the battery 500 supplies power to the telescopic mechanism 200. The battery 500 is electrically connected to the double-headed motor 343 through a wire when the battery 500 supplies power to the clamping mechanism 300. Of course, in some other optional embodiments, the battery 500 may not be provided, but the telescopic mechanism 200 and the clamping mechanism 300 may be powered by connecting the plug to the mains.

[0060] In some optional embodiments, the ground wire hanging device further includes a controller 600, a remote control terminal 800 and a communication unit 700, and the drive motor 220 of the telescopic mechanism 200 and the double-headed motor 343 of the clamping mechanism 300 are both connected to the controller 600, so that the controller 600 controls the drive motor 220 to realize the extension or retraction action of the telescopic mechanism 200 and controls the double-headed motor 343 to realize the clamping and releasing action of the wire by the clamping mechanism 300. The communication unit 700 is electrically connected to the controller 600, and the remote control terminal 800 is signal-connected to the communication unit 700. In this way, the operator can issue a control action instruction to the telescopic mechanism 200 and the clamping mechanism 300 through the remote control terminal 800, and the communication unit 700 transmits the instruction to the controller 600 after receiving the instruction, and the controller 600 controls the telescopic mechanism 200 and the clamping mechanism 300 to perform the corresponding action. This enables the operator to remotely control the ground wire hanging device to perform ground wire hanging operations, which on the one hand increases the operator's safety, and on the other hand avoids the operator's time spent on arriving at the ready location to hang the wire, thereby improving the efficiency of ground wire hanging.

[0061] It can be understood that the telescopic mechanism 200 and the clamping mechanism 300 are both connected to the controller 600, which means that the driving motor 220 in the telescopic mechanism 200 and the double-headed motor 343 in the clamping mechanism 300 are electrically connected to the controller 600. The communication unit 700 and the remote control terminal 800 both have the function of sending and receiving signals, and can realize signal interaction.

[0062] Optionally, the communication unit 700 and the remote control terminal 800 are connected via wireless signals. Of course, in some other implementations, the communication unit 700 and the remote control terminal 800 may also be connected via wired signals.

[0063] Regarding the setting positions of the controller 600 and the communication unit 700 , in some optional implementations, the controller 600 and the communication unit 700 may be fixed on the base 100 .

[0064] It can be understood that when a battery 500 is provided on the base 100 , the controller 600 is electrically connected to the battery 500 , and the battery 500 supplies power to the controller 600 , the telescopic mechanism 200 , and the wire clamping mechanism 300 .
