[0002] With the continuous development and improvement of the power system, the importance of grounding wires in the power system has become increasingly prominent. As an important safety protection measure in the power system, the correct and rapid installation of grounding wires is crucial to ensure the safe operation of the power system.

[0003] In the existing grounding wire installation process, workers mainly rely on manually climbing the pole to extract the grounding wire to the designated position for installation. However, due to the limitations of human height and the length of the grounding wire pole, installers often need to constantly adjust their positions to approach the line for grounding wire installation. This frequent adjustment not only increases the difficulty of work, but may also lead to insufficient safety distance between the human body and the line and equipment, increasing the risk of electric shock and falling from height. When installing the grounding wire, workers need to constantly rotate the operating rod to fix the grounding wire, which will cause hand fatigue, especially when wearing insulating gloves, the operation is more difficult.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a grounding wire installation auxiliary tool, including a support assembly 100, which lifts the grounding wire 303c-2 to below the installation position through a lifting assembly 300, and slides the sliding rod 201 to facilitate personnel on the rod to pick it up for installation.

[0030] Specifically, the support assembly 100 includes a pole tower 101, a hoop 102 sleeved on the outer wall of the pole tower 101, an arm 103 provided on the side wall of the hoop 102, a fixing cylinder 104 provided below the arm 103, and first slide grooves 104a provided on both sides of the fixing cylinder 104;

[0031] The moving component 200 includes a sliding rod 201 arranged inside the fixed cylinder 104, a connecting column 201a arranged on the outer wall of the sliding rod 201, a accommodating cavity 202 opened on the outer wall of the sliding rod 201, a movable plate 202a arranged inside the accommodating cavity 202 and a connecting cylinder 203 arranged on the outer wall of the fixed cylinder 104; the lifting component 300 includes a stabilizing frame 301 arranged on the outer wall of the sliding rod 201, a second sliding groove 301a opened on the outer wall of the stabilizing frame 301, a first pulley 302 movably arranged inside the stabilizing frame 301 and a second pulley 303 arranged below the first pulley 302.

[0032] The hoop 102 is composed of two semicircular plates, which are fastened with bolts and are movably mounted on the outer wall of the pole tower 101; the arm 103 is fixedly connected to the outer wall of the hoop 102; the interior of the fixed cylinder 104 is a hollow structure, which is fixedly connected to the arm 103; a connecting column 201a is provided at one end of the sliding rod 201, and the other end extends out of the fixed cylinder 104 and is connected to the pressing plate 201b; the connecting column 201a is arranged inside the fixed cylinder 104; a receiving cavity 202 is opened on the outer wall below the connecting column 201a, and the movable plate 20 2a is fixedly connected to the inner wall of the accommodating chamber 202; the connecting tube 203 is arranged on the outer wall below the fixed tube 104; the stabilizing frame 301 passes through the first sliding groove 104a to be connected to the outer walls on both sides of the sliding rod 201, and slides with the first sliding groove 104a; the second sliding groove 301a is opened on the outer walls on both sides of the stabilizing frame 301, and the stabilizing frame 301 provides support for the first pulley 302 without affecting the sliding of the first pulley 302. The first pulley 302 is a fixed pulley, and the second pulley 303 is a movable pulley.

[0033] Preferably, a first slot 104b and a second slot 104c are provided below the fixed cylinder 104, and a block 202a-1 is provided at one end of the movable plate 202a, and the block 202a-1 is movably matched with the first slot 104b and the second slot 104c respectively.

[0034] Among them, one end of the movable plate 202a is fixedly connected to the inner wall of the accommodating chamber 202, and the other end is fixedly connected to the block 202a-1; the side wall of the block 202a-1 is an inclined surface, so when the person on the rod pushes the pressure plate 201b, it is easy to disengage from the second slot 104c.

[0035] Preferably, a pressing plate 201b is provided on one end surface of the outer wall of the sliding rod 201, and a limiting plate 201a-1 is provided on the outer wall of one end surface of the connecting column 201a.

[0036] Among them, the setting of the pressure plate 201b makes it convenient for the personnel on the pole to push the sliding rod 201 to move the grounding wire 303c-2 away from the pole tower 101; one end of the connecting column 201a extends out of the fixed tube 104 and is connected to the limiting plate 201a-1. The setting of the limiting plate 201a-1 is to prevent the entire connecting column 201a from entering the fixed tube 104 when the first elastic member 201a-2 is released.

[0037] In summary, when the grounding wire 303c-2 needs to be installed, the ground personnel first pull the pull rope 301b to make the second pulley 303 rise, so that the trigger plate 303b presses against the matching plate 301c-2, and further makes the slide plate 301c slide upward in the second slide groove 301a, and press the movable column 203b to make the block 202a-1 disengage from the first slot 104b and enter the second slot 104c, so that it is convenient for the personnel on the pole to take the grounding rod 303c-1, avoiding the need to lean out to take it due to the long distance, thereby reducing the danger of high-altitude operation.

[0038] Example 2, reference Figure 2 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the trigger plate 303b presses against the matching plate 301c-2, so that the movable column 203b presses the block 202a-1, so that the slide bar 201 slides in the first slide groove 104a.

[0039] Specifically, the outer wall of the connecting column 201a is sleeved with a first elastic member 201a - 2 , and the interior of the connecting tube 203 is provided with an active cavity 203a .

[0040] Among them, the first elastic member 201a-2 is a compression spring, which is sleeved on the outer wall of the connecting column 201a, one end of which is connected to the sliding rod 201, and the other end is connected to the inner wall of the fixed tube 104 close to the connecting column 201a; when the clamping block 202a-1 is clamped with the first clamping groove 104b, the first elastic member 201a-2 is in a compressed state; when the clamping block 202a-1 is clamped with the second clamping groove 104c, the first elastic member 201a-2 is in a released state.

[0041] Preferably, a movable column 203 b is provided inside the movable cavity 203 a , and a convex plate 203 c is provided on the inner wall of the connecting tube 203 .

[0042] Preferably, a protrusion 203b-1 is provided on the outer wall of the movable column 203b, and a second elastic member 203c-1 is provided between the protruding plate 203c and the protrusion 203b-1.

[0043] Preferably, the stabilizing frame 301 is slidably matched with the first sliding groove 104a, a pull rope 301b is provided below the stabilizing frame 301, and the first pulley 302 is connected to the second pulley 303 via the pull rope 301b.

[0044] Among them, the connecting tube 203 corresponds to the position of the first slot 104b, and the movable cavity 203a is connected to the first slot 104b; one end of the movable column 203b is movably arranged inside the movable cavity 203a, and the other end extends out of the connecting tube 203; the protrusion 203b-1 is arranged inside the movable cavity 203a, and the protrusion 203b-1 is integrally connected with the movable column 203b; the second elastic member 203c-1 is a compression spring, which is arranged inside the movable cavity 203a and sleeved on the outer wall of the movable column 203b; one end of the pull rope 301b is connected to the outer wall below the stabilizing frame 301, and after being wound around the first pulley 302 and the second pulley 303, the other end is connected to the hands of the ground staff, so that the ground staff can cooperate with the staff on the pole to operate.

[0045] In summary, when the ground staff pulls the pull rope 301b, the second pulley 303 drives the grounding rod 303c-1 to rise. At this time, the grounding wire 303c-2 is far away from the pole tower 101, so as to avoid affecting the work of the staff on the pole during the ascent, resulting in insufficient safety distance between the human body and the line and equipment. Further, the carrying frame 303a drives the trigger plate 303b to rise, so that the trigger plate 303b supports the matching plate 301c-2, so that the slide plate 301c slides upward in the second slide groove 301a. When the slide plate 301c rises, it can press the movable column 203b. At this time, the second elastic member 203c- 1 is compressed, and one end of the movable column 203b close to the fixed cylinder 104 presses the block 202a-1, so that the block 202a-1 is separated from the first slot 104b and retracted into the accommodating chamber 202. At this time, the first elastic member 201a-2 is released, so that the slide bar 201 slides in the first slot 104a toward the clamp 102, so that the block 202a-1 is stuck in the second slot 104c, so that the lifting assembly 300 slides to a position close to the pole tower 101, which is convenient for the staff on the pole to reach out and take it, reducing the danger of the staff on the pole having to lean out to take it due to the long distance.

[0046] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that when installing and removing the grounding wire 303c-2, the grounding rod 303c-1 needs to be continuously rotated, and the installer wears insulating gloves for installation, and the hands will be fatigued due to the continuous twisting of the grounding rod 303c-1. The grounding rod 303c-1 can be hung on the hook 303c, and the grounding wire 303c-2 can be pushed to a place away from the tower 101 by pushing the pressure plate 201b.

[0047] Specifically, a slide plate 301c is slidably provided inside the second slide groove 301a, grooves 301c-1 are provided on both sides of the outer wall of the slide plate 301c, and a matching plate 301c-2 is provided on the outer wall of the slide plate 301c.

[0048] Preferably, a bearing frame 303a is movably provided outside the second pulley 303, and a trigger plate 303b is provided on the outer wall of the bearing frame 303a. The trigger plate 303b is movably matched with the matching plate 301c-2.

[0049] Preferably, a hook 303c is provided below the carrying frame 303a, a grounding rod 303c-1 is hung above the hook 303c, and a grounding wire 303c-2 is provided on the outer wall of the grounding rod 303c-1.

[0050] Among them, two grooves 301c-1 are respectively provided on both sides of the slide plate 301c. When the slide plate 301c slides in the second slide groove 301a, the grooves 301c-1 slide on the side walls of the stabilizing frame 301, guiding the sliding of the slide plate 301c and preventing the slide plate 301c from sliding left and right in the second slide groove 301a; the slide plate 301c and the matching plate 301c-2 are an integrally connected structure. When the matching plate 301c-2 is subjected to a thrust from below, the slide plate 301c can rise in the second slide groove 301a; the supporting frame 303a supports the second pulley 303, and the trigger plate 303b and the supporting frame 303a are an integrally connected structure; the hook 303c is fixedly arranged under the supporting frame 303a, and is used to fix the grounding rod 303c-1. When the pull rope 301b is pulled, the grounding rod 303c-1 rises.

[0051] In summary, when installing and removing the grounding wire 303c-2, the grounding rod 303c-1 needs to be rotated continuously. However, the installers wear insulating gloves for installation, and their hands will become tired due to the continuous twisting of the grounding rod 303c-1. The grounding rod 303c-1 can be hung on the hook 303c for temporary repair. If it needs to be installed again, the pressing plate 201b can be pushed to make the block 202a-1 disengage from the second slot 104c and enter the first slot 104b, thereby pushing the grounding wire 303c-2 to a place away from the tower 101. At this time, the ground personnel can reduce the pulling force on the pull rope 301b, so that the second pulley 303 drives the load-bearing frame 303a to descend, which is convenient for the next ascent work.
