Description

Technical Field

[0001] This invention relates to the field of drilling tools, and in particular to a clip gun and method for installing a 10kV line insulation protective cover while it is energized. Background Technology

[0002] With increasingly stringent requirements for power supply reliability, live-line maintenance work has become increasingly important. The gradual advancement of insulation upgrades in urban power distribution networks places higher demands on insulation restoration after live-line work, making the installation of insulating protective covers a crucial step after operations such as disconnecting live conductors and installing grounding rings.

[0003] Currently, in the field of installing insulating protective covers for live-line work, there is a lack of corresponding professional tools, and manual labor remains the primary method. During these operations, maintenance personnel need to wear three layers of protective gloves (labor gloves, insulating gloves, and puncture-resistant gloves). Insulating gloves are standardized in size and cannot be custom-made to fit individual workers; the fingers are loose, large, and inflexible. Furthermore, various insulating protective covers suffer from narrow skirts and short rivets, leading to three major challenges for maintenance personnel when installing these covers while wearing three layers of gloves: ① difficulty in accurately gripping the rivets of the insulating protective cover; ② difficulty in aligning the rivets with the small holes on the narrow skirts of the insulating protective cover; ③ difficulty in effectively using finger strength to push the rivets. Taking an amp cover as an example, an amp cover contains at least 10 short rivets. In actual live-line work, fixing a single rivet takes an average of 30 seconds. For a three-phase line, it takes 15 minutes to completely restore insulation after connecting the lead wire. This low work efficiency has a significant impact on power supply reliability. In terms of safety, the 5-minute arm-raising operation for each phase will cause great fatigue to the maintenance personnel, seriously affecting the safety of the operation. At the same time, the continuous soreness of the maintenance personnel's arms will lead to poor construction quality, and there is a risk of the insulation protective cover falling off. This will create a weak link at the exposed electrical connection, which is not conducive to the safe and stable operation of the power distribution line.

[0004] Therefore, this invention proposes a clip gun for live installation of 10kV line insulation protective covers, in order to solve the problems of difficult riveting installation, low work efficiency, and high manpower consumption in the prior art. Summary of the Invention

Detailed Implementation

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] Example 1

[0038] A specific embodiment of the present invention discloses a clip gun for live-mounting a 10kV line insulation protective cover, such as... Figure 1 , Figure 2 As shown, it includes: an insulating shell 2, a first movable block 4, a second movable block 6, and a displacement pushing assembly; a nail box 26 is installed on the insulating shell 2, and a rivet is provided inside the nail box 26, which can fall into the interior of the insulating shell 2 through a feed groove 19; a perforation groove 20 for placing an insulating protective cover is provided on the insulating shell 2; a first ejector pin 12 is fixedly provided on the first movable block 4, and a second ejector pin 17 is fixedly provided on the second movable block 6, the first movable block 4 and the second movable block 6 are respectively located on both sides of the perforation groove 20, and the first ejector pin 12 and the second ejector pin 17 are arranged opposite to each other; the displacement pushing assembly can drive the first movable block 4 and the second movable block 6 to reciprocate linearly relative to the insulating shell 2; when the second ejector pin 17 is displaced, it can punch a hole in the insulating protective cover, and when the first ejector pin 12 is displaced, it can push the rivet to be installed in the hole in the insulating protective cover.

[0039] Specifically, in order to enable the second ejector pin 17 to punch holes in the rubber insulating protective cover, the front end of the second ejector pin 17 is designed with an annular punch 27; such as Figure 7 As shown. Preferably, the annular punch 27 has a tapered cutting edge with a trapezoidal cross-section, and the outer wall thickness of the annular punch 27 is less than the inner wall thickness; specifically, the axial depth of the annular punch 27 is less than the thickness of the insulating protective cover (rubber insulating protective cover).

[0040] In use, the edge of the rubber insulating protective cover is placed in the perforated groove 20 and fits against the side of the perforated groove 20. Furthermore, the side of the perforated groove 20 is opened with a round hole that allows the second ejector pin 17 to pass through. Thus, the annular punch 27 can cooperate with the perforated groove 20 to form a shearing action, effectively penetrating the rubber insulating protective cover without tearing or deforming the material.

[0041] In this embodiment, the rivet is a dumbbell-shaped structure with both ends expanding and the middle diameter being smaller than the diameters at both ends, ensuring a secure lock after installation and preventing it from falling off. When the first ejector pin 12 pushes the rivet through the drilled rubber insulating protective cover, the expanded structure at one end of the rivet applies pressure to the rubber insulating protective cover, causing it to deform elastically. Then, the narrow section in the middle of the rivet passes through the hole to complete the installation. After installation, the narrow section in the middle of the rivet mates with the drilled hole, and the two ends of the rivet form a self-locking structure, achieving rapid fixation of the insulating protective cover.

[0042] like Figure 2 , Figure 4 As shown, the displacement pushing assembly includes: a drilling drive device 1, a guide rail 7, and a lead screw 8; the first movable block 4 and the second movable block 6 are both slidably mounted on the guide rail 7, and the first movable block 4 and the second movable block 6 are both threadedly connected to the lead screw 8; the drilling drive device 1 is used to drive the lead screw 8 to rotate, and when the lead screw 8 rotates forward or reverse, it can drive the first movable block 4 and the second movable block 6 to slide and displace along the guide rail 7 in the forward or reverse direction.

[0043] Specifically, the punching drive device 1 includes a drive motor, a control circuit board, and a control button; the forward and reverse rotation of the drive motor is controlled in real time by the control button and the control circuit board; in this embodiment, the structural principle of the punching drive device 1 is within the scope of what those skilled in the art can achieve, and will not be described in detail in this embodiment.

[0044] Furthermore, a top flange sleeve 9 and a tail flange sleeve 18 are installed on the front and rear sections of the insulating outer shell 2; the guide rail 7 is fixedly installed between the top flange sleeve 9 and the tail flange sleeve 18. Figures 3-6 As shown, in this embodiment, the tail flange sleeve 18 is installed at the left end of the drilling drive device 1. The outer walls of the top flange sleeve 9 and the tail flange sleeve 18 are fitted with an insulating outer shell 2. The drilling drive device 1 is internally equipped with a rechargeable lithium battery to meet the needs of high-altitude or outdoor operations. Figure 5As shown, the upper outer wall of the insulating shell 2 is provided with a feeding groove 19 and a drilling groove 20. The feeding groove 19 is located at the left end of the drilling groove 20. The feeding groove 19 and the drilling groove 20 arranged side by side can facilitate the need for drilling holes and then nailing the rubber insulating protective cover.

[0045] In this embodiment, as Figure 2 , Figure 3 As shown, the right end connecting shaft of the lead screw 8 passes through the tail flange sleeve 18 and is connected to the left end output end of the drilling drive device 1. The first movable block 4, the fixed block 5, and the second movable block 6 are distributed from left to right on the inner wall of the insulating shell 2. The first movable block 4, the fixed block 5, and the second movable block 6 are located between the top flange sleeve 9 and the tail flange sleeve 18. The lead screw 8 is connected to the output end of the drilling drive device 1, which can drive the lead screw 8 to rotate.

[0046] Specifically, two guide rails 7 are arranged side by side, and the first movable block 4 and the second movable block 6 are respectively provided with a first sliding groove 11 and a second sliding groove 16; the first sliding groove 11 and the second sliding groove 16 are used for sliding engagement with the guide rails 7. The first movable block 4 and the second movable block 6 are respectively provided with a first threaded groove 10 and a second threaded groove 15; the first threaded groove 10 and the second threaded groove 15 can be screwed into the lead screw 8.

[0047] like Figure 2 , Figure 3 As shown, two sets of guide rails 7 are symmetrically distributed front and rear between the top flange sleeve 9 and the tail flange sleeve 18. A lead screw 8 is rotatably installed at the center position between the top flange sleeve 9 and the tail flange sleeve 18. Two sets of first sliding grooves 11 and first threaded grooves 10 are symmetrically distributed front and rear at both ends of the first movable block 4. Two sets of second sliding grooves 16 and second threaded grooves 15 are symmetrically distributed front and rear at both ends of the second movable block 6. The first sliding grooves 11 and second sliding grooves 16 are slidably engaged with the two guide rails 7, and the first threaded grooves 10 and second threaded grooves 15 are screwed into the lead screw 8. When the lead screw 8 rotates, it drives the first movable block 4 and the second movable block 6 to slide synchronously along the guide rails 7 through the screwing action, thereby realizing the drilling of the insulating protective cover and the pushing and installation of the rivets through the second ejector pin 17 and the first ejector pin 12.

[0048] In this embodiment, the segmented threaded engagement between the lead screw 8 and the first screw groove 10 and the second screw groove 15 enables the sequential action of the second movable block 6 and the first movable block 4. Without the need for an additional control system, the second ejector pin 17 and the first ejector pin 12 can be driven to complete the timing linkage of the drilling tool drilling first and then nailing, simplifying the structure while improving reliability and increasing the efficiency of drilling and nailing the rubber insulating protective cover.

[0049] Furthermore, a fixing block 5 is provided between the first movable block 4 and the second movable block 6, and the fixing block 5 is fixedly installed on the guide rail 7; a rivet bracket 13 is provided on the side of the fixing block 5; a slot aligned with the feed groove 19 is provided above the rivet bracket 13, so that the rivet can be supported by the rivet bracket 13 when it falls into the interior of the insulating shell 2. In this embodiment, the rivets are arranged sequentially in the rivet box 26 and accurately enter the rivet bracket 13 through the feed groove 19. Through the supporting and positioning function of the rivet bracket 13, it is ensured that the rivet can accurately enter the predetermined position in the punched groove 20 inside the insulating shell 2 under the ejection action of the first ejector pin 12, avoiding misalignment or jamming.

[0050] Specifically, such as Figure 2 , Figure 4 As shown, the fixing block 5 is fixed to the center of the two sets of guide rails 7. The fixing block 5 has through slots 14 extending through both ends to allow the lead screw 8 to rotate relative to the fixing block 5 while keeping the fixing block 5 stationary. A rivet bracket 13 is installed at the left edge of the fixing block 5, and the rivet bracket 13 communicates with the round hole through the fixing block 5. A first ejector pin 12 is fixed to the right edge of the first movable block 4, and a second ejector pin 17 is fixed to the left edge of the second movable block 6.

[0051] Furthermore, such as Figure 6 As shown, a nail box holder 21 is connected to the lower part of the nail box 26, and the nail box 26 is mounted on the insulating shell 2 through the nail box holder 21.

[0052] Furthermore, multiple rivets are installed side by side inside the rivet box 26; the rivet box 26 is also provided with a push block 22 and a return spring 23; the push block 22 is in pressure contact with the rivets, and the return spring 23 is connected to the push block 22, and the return spring 23 can automatically fill the rivet into the rivet bracket 13 through the push block 22.

[0053] Furthermore, such as Figure 6 As shown, the bottom of the nail box 26 has a through hole 25; a retaining strap 24 is slidably installed in the through hole 25; the retaining strap 24 is used to support the bottommost rivet inside the nail box 26. The retaining strap 24 is used to block the rivet and prevent it from sliding out of the nail box 26 under the action of gravity or vibration; when the push block 22 inside the nail box 26 pushes the rivet to move under the elastic force of the return spring 23 to perform nail replacement, the bottommost rivet falls into the slot of the rivet bracket 13 one by one, realizing the single nail replacement action.

[0054] like Figure 6As shown, the outer wall of the insulating shell 2 is fitted with a nail box holder 21, and a rivet box is installed inside the nail box holder 21. The rivet box includes a nail box top cover 3 and a nail box 26. The nail box top cover 3 is fixed to the upper end of the nail box 26. Specifically, two sets of return springs 23 are symmetrically distributed on the left and right sides and fixed to the inner wall of the upper end of the nail box top cover 3. A push block 22 is fixed to the lower end of the return spring 23. The lower end of the nail box 26 is installed in a slot in the nail box holder 21. The outer wall of the push block 22 is flush with the nail slot in the nail box 26. The inner walls fit together; through holes 25 are provided at the bottom edges of the left and right ends of the nail box 26, which are connected to the nail groove inside, to prevent the pull strap 24 from sliding in the through holes 25; in this embodiment, the rivet box composed of a return spring 23 and a push block 22 can store and collect the rivets required for nailing, and the return spring 23 and the push block 22 can automatically push the rivets inside the nail box 26 into the feed trough 19 to improve its convenience in high-altitude or field operations.

[0055] When implementing, such as Figures 3-5 As shown, in this embodiment, the lead screw 8 passes through the through groove 14 and is adapted to the first screw groove 10 and the second screw groove 15. The outer wall of the guide rail 7 is in contact with the inner wall of the first sliding groove 11 and the second sliding groove 16. The first screw groove 10 and the second screw groove 15 adapted to the lead screw 8 can drive the first movable block 4 and the second movable block 6 to perform left and right displacement adjustment. The rivet bracket 13 corresponds to the feed groove 19. The first ejector pin 12 and the second ejector pin 17 are both corresponding to the axis of the rivet bracket 13. The lead screw 8 is... When rotated, the second ejector pin 17 can be moved towards the rivet bracket 13, thereby drilling holes in the rubber insulating protective cover; the drilling groove 20 is located between the fixed block 5 and the second movable block 6, the first ejector pin 12 is adapted to the rivet bracket 13, and the corresponding first ejector pin 12 and rivet bracket 13 can realize the first ejector pin 12 to push the rivet; when the screw 8 rotates in the opposite direction, it drives the first movable block 4 and the first ejector pin 12 to move, pushing the rivet in the rivet bracket 13 into the hole pre-drilled in the second ejector pin 17.

[0056] Example 2

[0057] A method for installing a 10kV line insulation protective cover while it is energized, using the snap-fit ​​gun described in Example 1 for automatic nailing installation of the insulation protective cover; including the following steps:

[0058] Step S1: Load multiple rivets into the rivet box 26, install the rivet box 26 onto the insulating shell 2, and align it with the feed chute 19;

[0059] Step S2: Place the insulating protective cover into the perforated slot 20 of the insulating outer shell 2; the displacement pushing component drives the second movable block 6 to move towards the perforated slot 20, and completes the perforation of the insulating protective cover through the second ejector pin 17;

[0060] Step S3: The displacement pushing component drives the first movable block 4 to move towards the punched groove 20, and pushes the rivet through the first pin 12 and through the hole completed in step S2 of the insulating protective cover, thus completing the riveting installation of the rubber insulating protective cover on the live wire.

[0061] Specifically, in step S1, during use, the rivet box 26 with rivets inside is first installed into the rivet box sleeve 21, and one end of the pull-out strap 24 is pinched to pull it out from the rivet box 26. The pull-out strap 24 that is not pulled out can prevent the rivets in the rivet box 26 from falling down. At this time, the return spring 23 in the compressed state pushes the push block 22 to automatically push the rivet along the rivet groove in the rivet box 26 into the feed groove 19 so that it falls into the rivet bracket 13 of the fixing block 5 to complete the pre-positioning of the rivet to be shot. Then, the operator can manually put the edge of the rubber insulating protective cover that needs to be drilled into the drilling groove 20.

[0062] In step S2, when drilling, if the drilling drive device 1 is a motor, the motor drives the lead screw 8 to rotate forward, causing the second movable block 6 to slide to the left along the guide rail 7, thereby driving the second ejector pin 17 on the second movable block 6 to move towards the fixed block 5, so that the second ejector pin 17 passes through the rubber insulating protective cover at the corresponding position to accurately drill the edge of the rubber insulating protective cover in the drilling groove 20.

[0063] In step S3, after drilling is completed, the drilling drive device 1 drives the starting screw 8 to reverse, thereby resetting the second movable block 6 and simultaneously driving the first movable block 4 to slide to the right along the outer wall of the guide rail 7. This pushes the first ejector pin 12 on the side of the first movable block 4 into the rivet bracket 13, and then the first ejector pin 12 pushes the rivet into the pre-drilled hole of the second ejector pin 17, thus completing the continuous action of drilling first and then shooting the rivet. The automated riveting process of the present invention can ensure that no manual intervention is required during the operation. The entire process is achieved by precisely controlling the forward and reverse rotation of the screw 8 by the motor, realizing the complete action cycle of drilling first and then automatically ejecting the rivet. This effectively improves the installation efficiency and operational safety of 10kV line insulation protection covers, reduces human operation errors, and ensures the safety of power maintenance personnel.

[0064] Furthermore, after the operation is completed, the lead screw 8 rotates in the reverse direction, causing the first movable block 4 and the second movable block 6 to reset in sequence. The next rivet in the rivet box 26 will be pushed by the reset spring 23 and the push block 22 to automatically fill the rivet bracket 13, waiting for the next cycle of use.

[0065] The method for installing an insulating protective cover for live-line work of the present invention, through the above steps S1-S3, utilizes the segmented thread structure formed by the lead screw 8, the first screw groove 10, and the second screw groove 15 to realize the sequential action of the second movable block 6 and the first movable block 4. Without the need for an additional control system, the second ejector pin 17 and the first ejector pin 12 can be driven to complete the sequential linkage action of the drilling tool drilling first and then shooting nails. This simplifies the structure, improves reliability, and enhances the efficiency of drilling and shooting nails into the rubber insulating protective cover, solving the problem of the existing drilling device having a single function and poor drilling efficiency.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
