Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic diagram of a ground wire of a portable ground wire suspension device according to an embodiment of the invention. Fig. 2 is an overall schematic view of a portable ground wire suspension device according to an embodiment of the invention. Fig. 3 is a schematic view of a ground wire handling bar of a portable ground wire suspension device according to an embodiment of the present invention. One end of the grounding wire 1 can be connected with a grounding wire hook 2, the grounding wire hook 2 is used for hanging the grounding wire 1 on the high-voltage line 6, and the other end of the grounding wire 1 is used for grounding. The ground wire 1 can be connected to the center axis of the ground wire hook 2 so that the ground wire hook 2 is constantly kept in a vertical direction by the weight of the ground wire 1. The ground wire suspension device may include: the ground wire connecting device comprises a first stop mechanism 3, a ground wire operating rod 4, a second stop mechanism 5, a pulley hook 7, a traction rope 8, a first connecting mechanism 9 and a second connecting mechanism 10. The first stop mechanism 3 may be provided on the ground wire 1. The ground wire operating lever 4 may be plural for end-to-end connection combination to support the ground wire hanger 2. A second stop mechanism 5 may be provided on the first ground wire operating lever 4. The pulley hanger 7 may be pre-hung to the high voltage line 6. A traction rope 8 may be used to pass through the pulley portion of the pulley hook 7, and one end of the traction rope 8 may be provided with a first coupling mechanism 9 and a second coupling mechanism 10. The first connecting mechanism 9 is connected with the first stopping mechanism 3 to drive the grounding wire 1 to move upwards under the condition that the other end of the traction rope 8 is pulled. The second connecting mechanism 10 can be connected to the second stop mechanism 5 to move the first ground wire operating lever 4 upward when the other end of the pulling rope 8 is pulled.
When the grounding wire 1 needs to be hung on the high-voltage line 6, the rigidity of the common grounding wire operating device and the strength of workers are insufficient because the distance between the common high-voltage line and the ground is relatively high. In the embodiment of the present invention, one end of the ground wire 1 may be connected to a ground wire hook 2, the ground wire hook 2 is used for hanging on the high-voltage line 6, and the other end of the ground wire 1 may be grounded, thereby completing the grounding operation for the high-voltage line 6. When the high-voltage line 6 needs to be grounded, the pulley hook 7 can be hung on the high-voltage line 6 in advance. The hauling cable 8 can pass through the pulley hook 7, so that when one end of the hauling cable 8 is pulled, the other end can be driven to move upwards. A first coupling mechanism 9 and a second coupling mechanism 10 may be provided at one end of the traction rope 8. The first connecting mechanism 9 and the first stopping mechanism 3 can be limited mutually, so that when the other end of the traction rope 8 is pulled, the ground wire 1 is also driven to move upwards due to the mutual limitation of the first stopping mechanism 3 and the first connecting mechanism 9. Because one end of the grounding wire 1 is grounded, and the other end of the grounding wire 1 is connected with the grounding wire hook 2, when the grounding wire hook 2 is driven to move up and hung on the high-voltage wire 6, the grounding wire 1 can be seen as a whole from the high-voltage wire 6 to the ground, and if the first connecting mechanism 9 is sleeved on the grounding wire 1 and then is limited with the first stopping mechanism 3, the first connecting mechanism 9 is not easy to be detached from the grounding wire 1, therefore, the first connecting mechanism 9 can be an openable and closable mechanism, and when the grounding wire needs to be detached, the first connecting mechanism 9 can be separated from the first stopping mechanism 3 and can be detached from the grounding wire 1 in an opened mode. The other end of the pull cord 8 may also be provided with a second attachment means 10. The second connecting mechanism 10 can be limited by the second stopping mechanism 5, so that when the other end of the pulling rope 8 is pulled, the first ground wire operating rod 4 can be driven to move upwards. When the other end of the hauling rope 8 is pulled, one end of the hauling rope 8 can be driven to move upwards because the pulley hook 7 converts the direction of the hauling rope 8. The first connecting mechanism 9 and the second connecting mechanism 10 at one end of the hauling rope 8 can drive the grounding wire 1 and the grounding wire operating rod 4 to move upwards until the grounding wire hook 2 is pulled to the position near the high-voltage line 6, and then the grounding wire hook 2 is hung on the high-voltage line 6 under the action of the grounding wire operating rod 4 and the hauling rope 8, so that grounding work is completed.
In one embodiment of the present invention, as shown in fig. 4, the ground wire suspension device may include a telescopic insulating rod 11. The telescopic insulating rod 11 can be arranged at the bottom of the pulley hook 7 for workers to hang the pulley hook 7 on the high-voltage line 6. The telescopic insulating rod 11 can be nested in multiple layers, and when the pulley hook 7 needs to be hung on the high-voltage line 6, the telescopic insulating rod 11 can be pulled out layer by layer until the pulley hook 7 is hung on the high-voltage line 6.
In one embodiment of the present invention, as shown in fig. 4, a scale mark 12 may be provided on a sidewall of the telescopic insulating rod 11. When the telescopic insulating rod 11 is pulled out, the scale mark 12 on the side wall of the telescopic insulating rod 11 can display the current length of the telescopic insulating rod 11. The worker can prepare a plurality of sections of the ground wire operating rods 4 according to the current length of the telescopic rod 11, so that when the first ground wire operating rod 4 is pulled, the rest ground wire operating rods 4 are connected to the bottom of the first ground wire operating rod 4.
In one embodiment of the present invention, as shown in fig. 5 and 6, the pulley hook 7 may include a hook 13 and a pulley 15.

When the conductive layer 14 is in contact with the high voltage line 6, if the high voltage line 6 has a high voltage, the alarm control module 17 may also control the locking latch mechanism 16 to lock the pulley 15, so that the pulley 15 cannot rotate, further blocking the movement of the traction rope 8 on the pulley 15.
In one embodiment of the present invention, as shown in fig. 7, the pulley 15 may be provided with a plurality of limiting holes 18 for the locking bolt mechanism 16 to pass through. The latching latch mechanism 16 may be located on the side of the pulley 15. In the case where the conductive layer 14 contacts the high voltage line 6, if the high voltage line 6 carries a high voltage, a stopper rod may be ejected toward the pulley 15 to pass through the stopper hole 18, thereby restricting the rotation of the pulley 15.
In one embodiment of the present invention, the telescopic insulating rod 11 may include a fixed foot rest 19. The fixed foothold 19 may be hinged at the bottom of the telescopic insulating rod 11. When pulley couple 7 need hang to high-tension line 6, if an independent flexible insulator spindle 11 is vertical to be placed, can cause its unstable condition because this flexible insulator spindle 11's length overlength, the existence of fixed pedal 19 can be fixed it in the bottom surface when this flexible insulator spindle 11 vertically extends for this flexible insulator spindle 11 is more stable. The fixed pedal 19 is hinged to the bottom of the telescopic insulating rod 11, the fixed pedal 19 can be retracted to the side of the telescopic insulating rod 11 when not in use at ordinary times, and when in use, the fixed pedal 19 can be opened and then stepped on the fixed pedal 19 to stabilize the telescopic insulating rod 11.

On the other hand, the fixing belt 21 can also prevent the ground wire 1 or the ground wire operating rod 4 from falling under the action of weight due to slipping of both hands or active separation of the pulling rope 8 when a worker pulls the pulling rope.
In one embodiment of the present invention, as shown in fig. 3, the bottom of the ground wire hook 2 may be provided with a snap male 22. A snap-in female head 23 may be provided on top of the first ground wire operating lever 4. The male snap head 22 and the female snap head 23 can cooperate to connect the ground wire lever 4 and the ground wire hook 2 together. When pulling the other end of the haulage rope 8, the first earth connection action bars 4 is pulled to move up, and the earth connection couple 2 connected with the first earth connection action bars 4 through the male joint 22 of joint and the female joint 23 of joint can also be driven to move up.
