The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, directional words such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0035] In order to solve the problem of low installation efficiency of line-type lightning arresters in the prior art, the present application provides a line gap lightning arrester installation auxiliary device.

[0036] like Figures 1 to 6 As shown, the line gap arrester installation auxiliary device includes a support structure 10, a first wearing structure 20, and a height adjustment structure 30. The support structure 10 includes a telescopic portion 11, which is telescopically arranged to adjust the height of the support structure 10. The first wearing structure 20 is used for wearing by the foot and is arranged on one end of the support structure 10. The height adjustment structure 30 is arranged on the support structure 10 and includes a driving member 31, a ratchet assembly 32, and a transmission assembly 33. The driving member 31 is drivingly connected to the telescopic portion 11 through the ratchet assembly 32 and the transmission assembly 33. The driving member 31 is rotatably arranged so that when the driving member 31 rotates in a first direction, the ratchet assembly 32 drives the telescopic portion 11 to extend to adjust the height of the support structure 10. The driving member 31 has an abutting end 311. When at least a portion of the support structure 10 is tilted in a predetermined direction driven by the foot, the abutting end 311 abuts against the working surface, allowing the driving member 31 to rotate in the first direction.

[0037] Applying the technical solution of this embodiment, the support structure 10 of the line gap lightning arrester installation auxiliary device includes a telescopic portion 11, which is telescopically arranged so that the height of the support structure 10 can be adjusted. The first wearing structure 20 is used for being worn by the foot and is arranged on one end of the support structure 10. The height adjustment structure 30 is arranged on the support structure 10 and includes a driving member 31, a ratchet assembly 32 and a transmission assembly 33. The driving member 31 is driven and connected to the telescopic portion 11 through the ratchet assembly 32 and the transmission assembly 33. The driving member 31 is rotatably arranged so that when the driving member 31 rotates in a first direction, the ratchet assembly 32 drives the telescopic portion 11 to extend to adjust the height of the support structure 10. The driving member 31 has an abutting end 311. When at least a portion of the support structure 10 is tilted in a preset direction driven by the foot, the abutting end 311 abuts against the working surface to rotate the driving member 31 in the first direction. In this way, the line gap lightning arrester installation auxiliary device in the present application actually adopts a "stilt" wearing design, that is, the staff wears the line gap lightning arrester installation auxiliary device on the feet through the first wearing structure 20 to support the body and increase the height, and the above-mentioned design of the height adjustment structure 30 allows the staff to adjust the height of the support structure 10 by tilting the support structure 10 to prompt the driving member 31 to abut and rotate against the ground, thereby adjusting the installation height of the staff, so that the staff only needs to walk directly and tilt the support structure 10 during the installation of the line-type lightning arrester to have a good installation position, thereby greatly reducing the labor intensity of the staff, eliminating the need for repeated climbing and carrying of the ladder, and improving the installation efficiency of the staff.

[0038] In this embodiment, the preset direction is the side of the worker's body, that is, the worker only needs to control the legs and feet to drive the upper end of the supporting structure to tilt toward the side of the body, and the abutting end 311 can abut and squeeze with the ground, and prompt the driving member 31 to rotate, and then drive the telescopic part 11 to extend through the ratchet assembly 32 and the transmission assembly 33 to achieve the effect of height adjustment.

[0039] like Figures 1 to 6As shown, the ratchet assembly 32 includes a ratchet 321 and a ratchet structure 322. The ratchet 321 is rotatably mounted on the support structure 10. The ratchet structure 322 is mounted on the driving member 31 and rotates synchronously with the driving member 31. The ratchet structure 322 has retractable ratchet teeth 3221. When the driving member 31 drives the ratchet structure 322 to rotate in a first direction, the ratchet teeth 3221 and the ratchet 321 cooperate to drive the ratchet 321 to rotate. When the driving member 31 drives the ratchet structure 322 to rotate in a second direction, the ratchet 321 pushes the ratchet teeth 3221 to move, and the ratchet 321 and the ratchet teeth 3221 stop cooperating. In this way, the above-mentioned setting enables the function of the ratchet assembly 32 to be realized, that is, when the driving member 31 drives the ratchet structure 322 to rotate along the first direction, the ratchet 321 and the ratchet 3221 cooperate with each other and drive the ratchet 321 to rotate, thereby realizing the extension of the telescopic part 11, and when the driving member 31 rotates to the maximum angle and rotates along the second direction to reset, the ratchet 321 can push the ratchet 3221 to move to avoid mutual cooperation between the two, thereby ensuring that the driving member 31 can be smoothly reset.

[0040] In this embodiment, the first direction and the second direction are clockwise and counterclockwise, respectively.

[0041] like Figures 3 to 5 As shown, the ratchet structure 322 further includes: a mounting housing 3222 disposed on the driver 31, the mounting housing 3222 having a mounting cavity and a through-hole communicating with the mounting cavity, the ratchet 3221 being retractably disposed in the through-hole; and a first elastic member 3223 disposed within the mounting cavity, one end of the first elastic member 3223 being connected to the ratchet 3221, the other end of the first elastic member 3223 being connected to the cavity wall of the mounting cavity, the first elastic member 3223 being configured to apply an elastic force to the ratchet 3221 to cause it to move toward the ratchet wheel 321. Thus, by providing the first elastic member 3223 to reset the ratchet 3221, it is possible to ensure a high degree of mating stability between the ratchet 3221 and the ratchet wheel 321 when the driver 31 rotates in the first direction, thereby ensuring high height adjustment stability for the support structure 10. Furthermore, the mounting housing 3222 provides a mounting environment for the first elastic member 3223 and the ratchet 3221.

[0042] like Figures 1 to 5As shown, the driving member 31 includes: a driving body 312 having an abutting end 311, the driving body 312 being rotatably mounted on the support structure 10; an arcuate mounting portion 313 disposed on the driving body 312, and a ratchet structure 322 disposed on the arcuate mounting portion 313; wherein the arcuate mounting portion 313 is disposed around the rotation axis of the driving body 312. Thus, the above arrangement enables a high degree of rotational synchronization between the ratchet structure 322 and the driving member 31, ensuring that the driving member 31 can stably drive the ratchet structure 322 to rotate. At the same time, because the arcuate mounting portion 313 is disposed around the rotation axis of the driving body 312, the rotation trajectory of the ratchet 3221 is coaxial with the rotation axis of the driving body, further improving the mating stability between the ratchet 3221 and the ratchet wheel 321.

[0043] In this embodiment, the arc-shaped mounting portion 313 is an arc-shaped plate segment.

[0044] In this embodiment, the driving body 312 comprises a rectangular frame and a plate-like structure mounted on the rectangular frame. The rectangular frame is rotatably mounted on the support structure 10. The plate-like structure is tilted toward the side away from the support structure 10, with the end of the plate-like structure away from the rectangular frame forming an abutment end 311. This tilted arrangement of the plate-like structure facilitates stable rotation of the driving member 31 when the operator tilts the support structure 10 to rotate the driving member 31. Furthermore, the rectangular frame also reduces the mass of the driving member 31, achieving a lightweight design and reducing the wearer's burden.

[0045] like Figures 1 to 5 As shown, the support structure 10 also includes a main body 12 and a mounting portion 13. The telescopic portion 11 is telescopically mounted on the main body 12, and the mounting portion 13 is mounted on the main body 12. The driving body 312 is rotatably mounted on the mounting portion 13 via the mounting portion 13. The transmission assembly 33 includes a gear 331 and a rack structure 332. The gear 331 and the ratchet 321 are both rotatably mounted on the mounting portion 13, and the rack structure 332 is mounted on the telescopic portion 11. The gear 331 and the ratchet 321 rotate synchronously, and the rack structure 332 and the gear 331 are meshed with each other. In this way, when the driving member 31 rotates in the first direction, its arc-shaped mounting portion 313 can drive the ratchet structure 322 to rotate, thereby driving the ratchet 321 to rotate. The ratchet 321 in turn drives the gear 331 to rotate. Finally, under the cooperation of the gear 331 and the rack structure 332, the telescopic portion 11 is driven to extend.

[0046] like Figures 1 to 5As shown, the mounting portion 13 includes: at least two mounting plates 131 disposed opposite each other; a first rotating member 132, with at least a portion of the driving body 312 located between the at least two mounting plates 131. The first rotating member 132 is disposed through the at least two mounting plates 131 and the driving body 312, so that the driving body 312 is rotatably mounted on the mounting portion 13; and a second rotating member 133, which is disposed through the at least two mounting plates 131. The gear 331 and the ratchet 321 are both mounted on the second rotating member 133. Thus, the first rotating member 132 can realize the rotation of the driving body 312, while the second rotating member 133 can realize the rotation of the gear 331 and the ratchet 321 while ensuring a high degree of rotational consistency between the two.

[0047] In this embodiment, the first rotating member 132 and the second rotating member 133 are both rotating shafts, and the second rotating member 133 is actually located between the driving body 312 and the arc-shaped mounting portion 313, that is, the ratchet 321 is located between the driving body 312 and the arc-shaped mounting portion 313, and the ratchet structure 322 is arranged on the arc-shaped mounting portion 313, and the ratchet 3221 is arranged toward the ratchet 321.

[0048] In this embodiment, a limiting sleeve is further provided on the first rotating member 132 to limit the setting position of the driving body 312 .

[0049] like Figure 1 and Figure 2As shown, the support structure 10 also includes at least two telescopic rods 14, the telescopic part of each telescopic rod 14 forms a telescopic part 11, and the main part of each telescopic rod 14 forms a main part 12. The line gap lightning arrester installation auxiliary device also includes: an abutment plate 40; a connecting structure 50, connecting two adjacent telescopic rods 14; wherein, the first wearing structure 20 is rotatably connected to one end of the telescopic rod 14 through a first connecting rod 60, and there are at least two first connecting rods 60, and at least two first connecting rods 60 are arranged in a one-to-one correspondence with at least two telescopic rods 14, so that the first wearing structure 20 can be flipped; the abutment plate 40 is rotatably connected to the other end of the telescopic rod 14 through a second connecting rod 70, and there are at least two second connecting rods 70, and at least two second connecting rods 70 are arranged in a one-to-one correspondence with at least two telescopic rods 14, so that the abutment plate 40 can be flipped. In this way, the above-mentioned arrangement forms a structure similar to a rectangular connecting rod between the two telescopic rods 14, the abutment plate 40 and the first wearing structure 20, and the connecting structure 50 can limit the maximum movement posture of the structure. In fact, during the walking process of the staff, the first wearing structure 20 can match the walking posture of the foot, that is, it can flip at a certain angle. At the same time, under the drive of the first connecting rod 60 and the second connecting rod 70 and the limitation of the connecting structure 50, the abutment plate 40 can also flip at a certain angle, thereby making the support structure 10 have a good walking simulation function, greatly reducing the walking difficulty of the staff and improving the walking comfort of the staff.

[0050] In this embodiment, there are two telescopic rods 14 , and the two telescopic rods 14 are arranged parallel to each other.

[0051] It should be noted that the number of telescopic rods 14 is not limited thereto and can be adjusted according to working conditions and usage requirements.

[0052] Specifically, the main body of the telescopic rod 14 is the sleeve portion, and the telescopic portion is a telescopic tube that can be telescoped even within the sleeve.

[0053] Optionally, the telescopic rod 14 has a self-locking function, that is, the telescopic part will automatically lock after being extended, and can only be retracted after the staff presses a specific button. The specific principle is relatively conventional and will not be elaborated here.

[0054] like Figure 1 and Figure 2As shown, the main body of the telescopic rod 14 is further provided with a connecting protrusion 141. The connecting structure 50 is an elastic structure, and the two ends of the connecting structure 50 are respectively connected to the connecting protrusions 141 of two adjacent telescopic rods 14. In this way, the connecting structure 50 provided with an elastic structure not only connects the connecting protrusions 141 of the two telescopic rods 14 to serve as a limit, but also provides a certain amount of movement through the elastic structure, further enhancing the simulation effect of the walking simulation function of the support structure 10 and further improving the walking comfort of the staff.

[0055] In this embodiment, two connecting protrusions 141 are provided on the main portion of the telescopic rod 14. The two connecting protrusions 141 on the two telescopic rods 14 are staggered to form an installation space between two adjacent connecting protrusions 141. The connecting structure 50 is disposed within the installation space so that the connecting structure 50 can provide elastic force to the connecting protrusions 141 along the height direction of the support structure 10. In this way, the above arrangement can prevent a worker from losing balance and falling due to an excessive height difference between the two telescopic rods 14 (i.e., an excessive tilt angle of the first wearing structure 20 or an excessive tilt angle of the abutment plate 40), thereby improving the safety of the line gap arrester installation auxiliary device.

[0056] In this embodiment, the connecting protrusion 141 is plate-shaped.

[0057] like Figure 1 As shown, the first wearing structure 20 includes: a support plate 21, which is installed on one end of the support structure 10; a panel 22, which is installed on the support plate 21 and is used to limit and stop the foot; and a first strap 23, which is installed on the support plate 21. In this way, the above arrangement not only supports the foot through the support plate 21, but also limits and stops the edge of the foot through the panel 22 and binds the foot through the first strap 23, thereby maximizing the wearing stability of the first wearing structure 20.

[0058] like Figure 1 As shown, the line gap arrester installation auxiliary device also includes a second wearing structure 80 for the legs to wear, and the second wearing structure 80 includes: a fixing rod 81, one end of the fixing rod 81 is set on the support structure 10; an arc-shaped limiter 82, which is set on the fixing rod 81 and is used to limit the stop with the legs; a second strap structure 83, which is set on the fixing rod 81. In this way, the above-mentioned arrangement can further wear and fix the line gap arrester installation auxiliary device and the legs of the staff through the second wearing structure 80, that is, the arc-shaped limiter 82 can accommodate the legs and the second strap structure 83 can bind the legs, further improving the wearing stability of the line gap arrester installation auxiliary device.

[0059] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0060] The support structure of the auxiliary device for installing a line gap lightning arrester includes a telescopic portion that is telescopically arranged so that the height of the support structure can be adjusted. A first wearing structure is used for being worn by a foot and is arranged on one end of the support structure. A height adjustment structure is arranged on the support structure and includes a driving member, a ratchet assembly, and a transmission assembly. The driving member is connected to the telescopic portion through the ratchet assembly and the transmission assembly. The driving member is rotatably arranged so that when the driving member rotates in a first direction, the ratchet assembly drives the telescopic portion to extend to adjust the height of the support structure. The driving member has an abutting end. When at least a portion of the support structure is tilted in a preset direction driven by the foot, the abutting end abuts against the working surface to rotate the driving member in the first direction. In this way, the line gap lightning arrester installation auxiliary device in the present application actually adopts a "stilt" wearing design, that is, the staff wears the line gap lightning arrester installation auxiliary device on the feet through the first wearing structure to support the body and increase the height, and the above-mentioned design of the height adjustment structure allows the staff to adjust the height of the support structure by tilting the support structure to cause the driving member to abut and rotate against the ground, and then adjust the installation height of the staff, so that the staff only needs to walk directly and tilt the support structure during the installation of the line-type lightning arrester to have a good installation position, thereby greatly reducing the labor intensity of the staff, eliminating the need for repeated climbing and carrying of the ladder, and improving the installation efficiency of the staff.
