Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of live working and cable accessory installation of power transmission and distribution lines, in particular to a device for live automatic installation of lightning overvoltage protector. BACKGROUND

[0002] During operation and maintenance of distribution overhead lines and cable lines, it is often necessary to complete the installation and replacement of line accessories under non-power-off or live conditions. Among them, lightning arresters and other lightning overvoltage protectors usually need to be quickly positioned, clamped and fastened between the cross arm and the conductor or wire; and the non-power-off replacement of fuse tubes often requires the quick clamping of line working components such as insulating clamps to a position and the construction of a temporary access to ensure power continuity.

[0003] Publication No. CN118645951A discloses a power grid lightning arrester and a live installation tool thereof, wherein the lightning arrester support includes a transversely arranged upper clamping block, a clamping block pawl and a push rod stop block, and the clamping block pawl and the push rod stop block are limited and clamped on the cross arm; at the same time, the live installation tool is composed of a fixed base module, an upper clamping block fixing module, a lightning arrester fixing module and a wire clamp installation module. However, the operation link of this type of scheme mainly focuses on the installation of lightning arresters, and the function is single, so additional tools need to be carried and replaced on site, resulting in an increase in steps, a decrease in efficiency and an increase in the risk of live working at high altitudes.

[0004] In addition, although a small number of integrated devices reduce the number of tools that need to be carried, the clamping mechanisms of these devices are often designed around a single movement form, and additional power components or manual disassembly and switching are required, which makes it difficult to meet the different needs of the two types of workstations for movement output under the same driving source, affecting the efficiency of live working.

[0005] Therefore, there is an urgent need for a device that can meet the differentiated needs of lightning arrester clamping and installation and line working component clamping in a live working scenario, and quickly switch the movement output required by different workstations, in order to improve the efficiency and safety of the work. SUMMARY

[0006] In order to overcome the above-mentioned defects of the prior art, the purpose of the embodiments of the present application is to provide a device for live automatic installation of lightning overvoltage protector, so as to solve the problems that in the existing live working tools, a single driving source cannot meet the differentiated clamping needs of lightning arresters and line working components, and the same tool cannot be used to quickly switch the clamping functions of lightning arresters and line working components.

[0026] The vertical length of the first stopper is greater than that of the second stopper, and the excess amount at both ends thereof is greater than the width of the arc-shaped protrusion;

[0027] The cross sections of the first stopper and the second stopper are both Z-shaped stopper edge structures; the arc-shaped protrusion enters from the end of the T-shaped guide channel and vertically slides along the T-shaped guide channel to limit the circumferential rotation of the clamping arm, and guide the bayonet to disengage from the positioning hole, so that the clamping arm moves vertically under the driving of the sleeve.

[0062] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0063] Embodiment 1

[0064] As shown in Figure 1 , Figure 4 , Figure 6 and Figure 10 , the embodiment provides a device for automatically installing lightning protection overvoltage protector with electric charge, comprising a shell 1, further comprising: an adjusting module comprising a driving assembly 9 and a stop assembly 10 arranged on one side of the shell 1; and a clamping module comprising a pair of clamping arms 7 arranged in an upper and lower manner; wherein the driving assembly 9 comprises a screw pipe 91 and a sleeve 92 movably matched with the screw pipe 91, one end of the clamping arm 7 is fixed to the outside of the sleeve 92 and is detachably connected with the screw pipe 91 through a clamping assembly 11; when the clamping assembly 11 is matched with the sleeve 92 relative to the fixed screw pipe 91, the screw pipe 91 is rotated to drive the two clamping arms 7 to rotate synchronously in the horizontal plane to clamp or release the lightning arrester 15; when the clamping assembly 11 is disengaged from the screw pipe 91 under the abutting action of the stop assembly 10, the screw pipe 91 is rotated to drive the sleeve 92, which drives the two clamping arms 7 to move vertically to clamp or release the insulation clamp 8.

[0065] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 6 to Figure 8 and Figure 10As shown, the screw pipe 91 of the driving assembly 9 continuously rotates, one end of the clamping arm 7 is fixed with the sleeve 92, and the clamping arm 7 can realize the switching of the two working modes in the two matching states of the clamping assembly 11 and the stop assembly 10. In the first matching state, the clamping assembly 11 is relatively fixed with the sleeve 92 of the screw pipe 91, the clamping assembly 11 is not in contact with the stop assembly 10, at this time, the screw pipe 91 rotates to drive the sleeve 92 fixed therewith to rotate synchronously, the sleeve 92 rotates to drive the clamping arm 7 fixed therewith to rotate; the pair of clamping arms 7 rotate synchronously in the horizontal plane, when the pair of clamping arms 7 rotate synchronously in the horizontal plane and approach each other, the lightning arrester 15 is clamped, and when the pair of clamping arms 7 rotate synchronously in the horizontal plane and move away from each other, the lightning arrester 15 is released. In the second matching state, the pair of clamping arms 7 are in the limit state of being opened, the clamping assembly 11 is in contact with the stop assembly 10, and the clamping assembly 11 is disengaged from the screw pipe 91 under the abutting action of the stop assembly 10, at this time, the relative fixation between the screw pipe 91 and the sleeve 92 is released; the screw pipe 91 continuously rotates, the clamping assembly 11 is always in contact with the stop assembly 10, which limits the circumferential rotation of the clamping arm 7, so that the circumferential rotation of the sleeve 92 fixed therewith is also limited. The screw pipe 91 continuously rotates to drive the sleeve 92 movably matched therewith to move axially along the screw pipe 91, the sleeve 92 further drives the clamping arm 7 fixed therewith to move axially, and then the clamping arm 7 is converted from the first working mode of rotating in the horizontal plane to the second working mode of vertical movement. When the pair of clamping arms 7 move synchronously and approach each other, the insulating clamp 8 is clamped, and when the pair of clamping arms 7 move synchronously and move away from each other, the insulating clamp 8 is released.

[0066] As shown in Figure 1 and Figure 2 As shown, the arc-shaped plate 71 is fixedly arranged on the inner side of the clamping arm 7 to fit the outer wall of the lightning arrester 15. The limiting part 23 of the connecting plate 22 supporting the lightning arrester 15 defines and supports the lightning arrester 15, and when the pair of clamping arms 7 rotate in the horizontal plane and approach each other, the lightning arrester 15 is formed in a circumferential clamping mode, and the lightning arrester 15 is prevented from swinging or deviating during lifting and alignment.

[0067] The adjusting module is installed on one side of the shell 1 through a support assembly 2. The support assembly 2 comprises a mounting plate 21 fixedly connected with the shell 1, a connecting plate 22 connected with the bottom end of the mounting plate 21 and extending to the side of the clamping space, and an L-shaped plate 24 arranged on the mounting plate 21; wherein the driving assembly 9 is installed on the L-shaped plate 24. In order to ensure the stability and coaxiality of the rotation of the screw tube 91, the L-shaped plate 24 for supporting the screw tube 91 can be integrally formed or detachably installed on the mounting plate 21, and the screw tube 91 is rotationally connected with the L-shaped plate 24 through a bearing, so as to realize the radial positioning and rotational support of the screw tube 91, and reduce the rotational resistance and swing. The side of the connecting plate 22 facing the lightning arrester 15 is provided with a limiting portion 23, which can be a supporting notch or an arc-shaped supporting surface matched with the outer shape of the end portion of the lightning arrester 15, and forms a guide limiting structure with the lateral stop edge thereof. Before the clamping arms 7 are folded and clamped, the limiting portion 23 supports and limits the posture of the lightning arrester 15, suppresses the swing or deflection in the lifting and alignment process, and provides a reference positioning for the circumferential clamping of the clamping arms 7, thereby improving the alignment efficiency and clamping reliability in the live installation process.

[0068] As shown in Figure 4 and Figure 6 In order to improve the use reliability of the clamping assembly, in an embodiment, the clamping assembly 11 is provided with a clamping pin 1101 and an arc-shaped protrusion 1102 arranged at the outer end portion of the clamping pin 1101. A guide hole 75 is formed in the clamping arm 7, a radial hole 921 is formed in the barrel wall of the sleeve 92, and a positioning hole 911 corresponding to the guide hole 75 and the radial hole 921 is formed in the screw tube 91. In use, the clamping pin 1101 is sequentially arranged in the guide hole 75 of the clamping arm 7, the radial hole 921 of the sleeve 92, and extends into the positioning hole 911 of the screw tube 91, so that the sleeve 92 and the screw tube 91 are relatively fixed, and the relative rotation between the sleeve 92 and the screw tube 91 is limited, so that the screw tube 91 drives the sleeve 92 and the clamping arm 7 to rotate synchronously when the screw tube 91 rotates, and the pair of clamping arms 7 rotate synchronously in the horizontal plane, thereby achieving clamping or releasing of the lightning arrester 15. The guide hole 75, the radial hole 921 and the positioning hole 911 correspond one by one, so as to ensure smooth and reliable rotation of the clamping pin 1101.

[0069] On this basis, as a preferred embodiment, a tension spring 1103 is sleeved on the clamping pin 1101 between the arc-shaped protrusion 1102 and the clamping arm 7, and the two ends of the tension spring 1103 are fixedly connected with the arc-shaped protrusion 1102 and the clamping arm 7 respectively. When the clamping pin 1101 is separated from the positioning hole 911, the tension spring 1103 can pull the clamping pin 1101, so that the clamping pin 1101 has a tendency to reset and insert into the positioning hole 911 in the direction of the sleeve 92, thereby improving the reliability of the clamping pin 1101 inserted into the positioning hole 911, and reducing the risk of misdisengagement after the station switching.

[0070] As shown in Figure 1 ,Figure 2 , Figure 9 and Figure 11 As shown, the drive assembly 9 includes a pair of helical tubes 91 rotatably mounted on an L-shaped plate 24. Sleeves 92 are fitted over the outer sides of the helical tubes 91 and threadedly connected to them. Each helical tube 91 has a fixed, meshing gear 93 at its bottom end. A first drive motor 94 is connected to either gear 93, driving the connected gear 93 to rotate. This gear 93 drives the meshing gear 93 to rotate synchronously, thus driving the two helical tubes 91 to rotate synchronously. The upper and lower external threads of each helical tube 91 have opposite directions of rotation, respectively threaded into the upper and lower sleeves 92 located at their respective ends. A limiting spring 95 is also fitted over the outer side of each helical tube 91, clamping between the two opposing sleeves 92. This provides axial elastic support to the two sleeves 92, ensuring continuous force during switching operations, thereby reducing axial clearance and movement during switching and improving consistency and stability of movement.

[0071] like Figure 2 , Figure 4 as well as Figure 6 to Figure 9 As shown, the stop assembly 10 includes a first stop 1001 and a second stop 1002, which extend vertically and are spaced apart on the mounting plate 21. The vertical length of the first stop 1001 is greater than that of the second stop 1002, and the upper and lower ends of the first stop 1001 extend beyond the upper and lower ends of the second stop 1002, respectively, by a distance greater than the width of the arc-shaped protrusion 1102. This allows the arc-shaped protrusion 1102 to pass over the second stop 1002 and abut against the first stop 1001 when the clamping arm 7 extends to its limit, thereby triggering a switching of the engagement state. The cross-sections of the first stop 1001 and the second stop 1002 are Z-shaped flange structures, forming a T-shaped guide channel between them for the arc-shaped protrusion 1102 to enter and slide vertically, thereby limiting the circumferential rotation of the arc-shaped protrusion 1102 and guiding its vertical movement.

[0072] In a preferred embodiment, the inner walls of the first stop 1001 and the second stop 1002 are provided with inclined structures. When the arc-shaped protrusion 1102 abuts against and slides against the inclined surface, the inclined surface generates a radial component force on the arc-shaped protrusion 1102, which drives the locking pin 1101 to move radially outward along the sleeve 92, so that the end of the locking pin 1101 exits the positioning hole 911 on the screw tube 91, thereby releasing the rotation restriction between the sleeve 92 and the screw tube 91, and realizing a smooth switch from the rotation output position to the vertical displacement position.

[0073] like Figure 3 and Figure 10As shown, the insulation clamp 8 is preferably arranged in pairs, and a short-circuit wire 81 is connected between the two insulation clamps 8, and the two ends of the short-circuit wire 81 are fixedly connected with the two insulation clamps 8, for constructing a temporary short-circuit conduction loop during the live working process. In order to prevent the insulation clamp 8 from being detached or slipping during clamping and displacement, recesses 72 are arranged on the opposite surfaces of the upper and lower clamping arms 7, and the recesses 72 are used to accommodate the clamping arms of the insulation clamp 8, so that the clamping arms can be embedded in the recesses 72, thereby limiting and supporting the insulation clamp 8 when the clamping arms 7 are relatively displaced. In a further embodiment, an adjusting plate 73 can be arranged in the recess 72 on one side in the vertical plane, and the adjusting plate 73 is slidably arranged along the recess 72; a threaded adjusting bolt 74 is correspondingly arranged on the clamping arm 7, and the end of the adjusting bolt 74 abuts against the adjusting plate 73. By rotating the adjusting bolt 74 to push the adjusting plate 73 in and out of the recess 72, additional pressure can be applied to the clamping arms embedded in the recess 72, so that the insulation clamp 8 can still be reliably supported and positioned by the unilateral clamping arm 7 when it is displaced or detached.

[0074] As shown in Figure 4 to Figure 11 In order to facilitate the clamping and cooperation relationship between the clamping arm 7 and the insulation clamp 8 at the vertical displacement station, the insulation clamp 8 is preferably of a resilient normally closed structure, and the clamping opening is opened by applying pressure to the clamping arms of the insulation clamp 8, and is closed by the elastic reset action of the insulation clamp 8 after the pressure is removed. Based on this, the specific clamping process is as follows: when the insulation clamp 8 needs to be clamped to construct a temporary conduction loop, the first driving motor 94 is first driven to rotate the gear 93 connected therewith, which drives the gear 93 engaged therewith to rotate synchronously, thereby driving the screw tube 91 to rotate, so that a pair of clamping arms 7 at the same height continue to rotate outward in the horizontal plane to the limit position; the arc-shaped protrusion 1102 passes over the second stop piece 1002 and abuts against the inclined surface of the first stop piece 1001, the latch 1101 moves radially outward to disengage from the positioning hole 911, and the arc-shaped protrusion 1102 enters the T-shaped guide channel to limit the rotation of the sleeve 92 and the clamping arm 7, and the screw tube 91 continues to rotate, which is converted into the axial displacement of the sleeve 92 along the screw tube. Subsequently, the rotation direction and stroke of the screw tube 91 are controlled to move the two clamping arms 7 arranged on the same side in the vertical plane away from or close to each other: when the two clamping arms 7 are close to each other, the clamping arms 7 apply pressure to the clamping arms of the insulation clamp 8 through the recess 72, so that the clamping opening of the insulation clamp 8 is forced to open, facilitating the guiding to the vicinity of the conductive end of the line member and completing the alignment; when the two clamping arms 7 are subsequently moved away from each other, the pressure of the clamping arms 7 on the insulation clamp 8 is removed, so that the clamping opening of the insulation clamp 8 is closed and stably buckled to the conductive end under the elastic reset action of the insulation clamp 8, completing the clamping.

[0075] As shown in Figure 1 In order to facilitate the lifting and alignment operation of the operating personnel on the ground, in an embodiment, the housing 1 and the insulating rod 6 are detachably connected, so that the device can be lifted by the insulating rod 6 to the cross arm 4 and completed.

[0076] Embodiment 2

[0077] Based on embodiment 1, the overall structure, driving mode and installation process of the clamping module and the adjusting module are unchanged, and as shown in Figure 1 and Figure 11 , a fixing assembly 3 is further arranged at the bottom end of the lightning arrester 15 to achieve reliable positioning and locking of the lightning arrester 15 at the cross arm 4.

[0078] Specifically, the lightning arrester 15 is provided with a clamping jaw 31 and a pressing plate 32 below the clamping jaw 31, the clamping jaw 31 is provided with an upper clamping opening 311 for clamping the horizontal section of the cross arm 4, and the pressing plate 32 is provided with a lower clamping opening 321 for clamping the vertical section of the cross arm 4; a strip-shaped slot 322 is formed on the pressing plate 32, and a first lifting eye bolt 33 is threaded through the strip-shaped slot 322 and connected with the clamping jaw 31. By tightening the first lifting eye bolt 33, the pressing plate 32 is driven to move upwards and the lower clamping opening 321 is clamped with the vertical section of the cross arm 4, so as to clamp and lock the cross arm 4 between the upper clamping opening 311 and the lower clamping opening 321, and achieve reliable fixing of the lightning arrester 15 at the cross arm 4.

[0079] Embodiment 3

[0080] Based on embodiment 1, as shown in Figure 1 , Figure 2 and as shown in Figure 12 , the embodiment further provides a drainage wire clamp assembly 12, a second lifting eye bolt 13 and a rotating cylinder 14 to facilitate the drainage side clamping and fixing and related fastening operations at a high place.

[0081] In order to facilitate the clamping and other operations at the drainage wire clamp assembly 12 on the ground, a second driving motor 16 is arranged in the housing 1, the output end of the second driving motor 16 is transmissionally connected with the rotating cylinder 14, and a clamping groove 1401 is formed at the top end of the rotating cylinder 14. The second lifting eye bolt 13 is arranged at the lower part of the drainage wire clamp assembly 12 and transmissionally connected with the drainage wire clamp assembly 12. The drainage wire clamp assembly 12 is a structure known in the art, which includes a fixed clamp 1201 and a movable clamp 1202 arranged oppositely, the second lifting eye bolt 13 is rotationally connected with the movable clamp 1202 and threadedly connected with a boss 1203 on the side of the fixed clamp 1201, so that when the second lifting eye bolt 13 is tightened, the movable clamp 1202 is driven to move towards the fixed clamp 1201 to clamp the electric wire 5. The lifting eye of the second lifting eye bolt 13 is insertable into the clamping groove 1401 of the rotating cylinder 14, so that when the rotating cylinder 14 rotates, the second lifting eye bolt 13 is rotated to achieve clamping and fixing of the electric wire 5 by the drainage wire clamp assembly 12.

[0082] As shown in Figure 2 , Figure 11 and Figure 12As shown, to solve the problem of manually tightening the first lifting ring bolt 33 and the second lifting ring bolt 13 at a high place, in a preferred embodiment, the clamping groove 1401 of the rotating cylinder 14 can also selectively insert the lifting ring part of the first lifting ring bolt 33, so that the first lifting ring bolt 33 is inserted into the clamping groove 1401 at the top of the rotating cylinder 14. Similarly, when the second driving motor 16 drives the rotating cylinder 14 to rotate, the tightening operation of the first lifting ring bolt 33 and the second lifting ring bolt 13 is realized, and the convenience and safety of live working are further improved.

[0083] To further improve the pressing and limiting effect of the first lifting ring bolt 33 on the clamping jaw 31 and the pressing plate 32, the following preferred embodiment is further given: a strip-shaped groove 322 is formed on the pressing plate 32, and the cross-sectional diameter of the lifting ring at the end of the first lifting ring bolt 33 is greater than the width of the strip-shaped groove 322, so that the first lifting ring bolt 33 is not easy to fall out during the tightening assembly process.

[0084] The following preferred embodiment can be further given: a strip-shaped groove 322 is formed on the pressing plate 32, and a disc-shaped extrusion part is provided on the first lifting ring bolt 33, and the diameter of the extrusion part is greater than the width of the strip-shaped groove 322, so as to form a more stable pressing and limiting effect under the cooperation condition of the strip-shaped groove 322.

[0085] In summary of the above embodiments 1-3, the driving assembly 9 of the present application drives the two screw pipes 91 to rotate synchronously through the two gears 93: in the case that the end of the clamping pin 1101 extends into the positioning hole 911, the relative rotation between the sleeve 92 and the screw pipe 91 is limited, and the rotation of the screw pipe 91 is transmitted to the circumferential rotation of the sleeve 92 and the clamping arm 7, so that the two clamping arms 7 relatively arranged in the same clamping module are synchronously folded or expanded in the horizontal plane, so as to realize the clamping or releasing of the lightning arrester 15.

[0086] When the clamping arm 7 is spread to the limit position in the horizontal plane, the arc-shaped protrusion 1102 passes the second stop piece 1002 and abuts against the inclined surface of the first stop piece 1001, the inclined surface generates a radial component force on the arc-shaped protrusion 1102, pushes the clamping pin 1101 to move radially outward and exit the positioning hole 911, thereby releasing the rotation limitation between the sleeve 92 and the screw pipe 91; at the same time, the arc-shaped protrusion 1102 enters the T-shaped guide channel between the first stop piece 1001 and the second stop piece 1002 and is limited by the T-shaped guide channel, so that the sleeve 92 and the clamping arm 7 enter the limited rotation state.

[0087] When the sleeve 92 is limited, the screw tube 91 continues to rotate to convert the threaded pair into the axial displacement of the sleeve 92; because the outer threads of the upper and lower sections of the screw tube 91 are opposite in rotation direction, the upper and lower sleeves 92 move towards or away from each other under the same direction of driving, thereby making the same-side clamping arms 7 in the vertical plane produce controllable relative close or relative far displacement, to complete the clamping or release of the conductive end with the insulating clamp 8. Among them, the limiting spring 95 provides axial pre-tightening and buffer support for the two sleeves 92, reduces the axial gap, stringing and impact in the station switching and opening and closing movement, reduces the risk of shaking and jamming, and ensures the continuity and consistency of the vertical displacement clamping action.

[0088] The foregoing merely illustrates some exemplary embodiments of the present application, and it is obvious to those skilled in the art that various modifications can be made to the described embodiments without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of the claims of the present application.
