Description

Technical Field

[0001] The invention relates to the technical field of electric power working tools, and in particular to a live tapping insulating operating tool. Background Art

[0002] With the continuous development of the power grid, live working technology has made significant progress, especially in the field of live working technology under high voltage, China has reached the world's leading level. The development of this technology not only meets the needs of safe operation of the line, but also improves the reliability of power supply in the distribution network. The application range of live working technology is wide, from the maintenance of high-voltage transmission lines to the inspection and maintenance of low-voltage distribution networks, it plays an indispensable role. Especially in the context of the development of digital power systems, live working technology has become one of the important means to ensure the stable operation of power systems.

[0003] At present, there are many jobs using 10kV live-line working special insulating operating rods, especially various line T-joint work. When using it, the lead wire needs to be installed on the wire clamp, and then the wire clamp with the lead wire installed is connected to the live line for T-joining through the insulating operating rod, and then the bolts on the wire clamp are locked. According to the statistics of the use of special tools for insulating rod joints in various field operations, there are roughly three shortcomings: First, the existing insulating operating rod is heavy, which can easily cause fatigue to the operators, resulting in deformation of the movements and reduced work quality; second, the maximum length of the existing insulating operating rod is 3.2m. Excluding the handheld part and the safe distance maintained with the live part, the actual effective distance is only about 2m, resulting in some field operations due to the same pole erection and other reasons. The operating length is limited, and the existing insulating operating rod is a single-section type and cannot be retracted for use, which makes it inconvenient to carry and occupies a large space when carried; third, the structure of the fixed wire clamp on the top of the existing insulating operating rod is loose due to different wire clamp models, which is not conducive to fixing on the line during operation. Summary of the invention

[0004] The invention provides a live tap insulation operating tool, which aims to be applicable to the installation of wire clamps of different models.

[0005] The present invention is implemented through the following technical scheme: a live tap insulation operating tool, comprising a wire clamp insulation rod, a wire clamp fixing piece for fixing the wire clamp and a wire clamp unlocking piece for loosening the wire clamp, wherein the wire clamp fixing piece is connected to one end of the wire clamp insulation rod;

[0006] The cross section of the wire clamp fixing piece is U-shaped, the wire clamp is installed on the wire clamp fixing piece, and a limiting unit for clamping the wire clamp is provided on the wire clamp fixing piece, and the limiting unit can change the width of the wire clamp clamped by the wire clamp fixing piece.

[0007] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0008] The wire clamp of this solution is fixed on the wire clamp fixing part through a limit unit. When in use, the wire clamp on the wire clamp fixing part is sent to the specified position of the live line through the wire clamp insulating rod, and then the bolts on the wire clamp are tightened by using other tools to fix the wire clamp on the live line, and then the wire clamp is released through the wire clamp unlocking part, so that the wire clamp fixing part and the wire clamp are smoothly separated, making it easy to remove the entire operating tool.

[0009] The limiting unit in this solution can change the width of the wire clamp held by the wire clamp fixing member, so it can be suitable for fixing wire clamps of different models, has a wide range of applications, and is easy to operate for wiring.

[0010] The cross section of the wire clamp fixing piece in this solution is U-shaped, so that the wire clamp fixing piece as a whole forms a U-shaped groove for installing the wire clamp, so that the wire clamp can be fixed in the U-shaped groove of the wire clamp fixing piece in cooperation with the limiting unit.

[0011] Furthermore, the limiting unit includes a pressure rod and an operating wrench, the pressure rod is threadedly connected to one side of the wire clamp fixing piece, and the operating wrench is located outside the wire clamp fixing piece and connected to one end of the pressure rod.

[0012] Beneficial effect: In the limiting unit of the present invention, the pressure rod is twisted by operating a wrench to move the pressure rod toward the inside or outside of the wire clamp fixing part, thereby making the pressure rod press against the wire clamp.

[0013] Furthermore, the limiting unit further comprises a connecting tube, the connecting tube is located outside the wire clamp fixing piece and is connected to the wire clamp fixing piece, and the pressure rod penetrates into the connecting tube.

[0014] Beneficial effect: The connecting tube in this solution can play a guiding role for the movement of the pressure rod.

[0015] Furthermore, the wire clamp unlocking member includes an operating hook and an operating hook insulating rod, the operating hook is connected to one end of the operating hook insulating rod, an operating hole is provided on the operating wrench, and the operating hook can be hooked in the operating hole to enable the operating wrench to tighten or loosen the pressure rod.

[0016] Beneficial effect: In this scheme, the wire clamp unlocking piece lifts the insulating rod of the operating hook so that the operating hook is hooked in the operating hole of the operating wrench, thereby facilitating the operation of loosening the pressure rod by rotating the operating wrench at a low position. After the wire clamp is separated from the pressure rod, the wire clamp fixing piece can be separated from the wire clamp fixed on the live circuit, so that the wire clamp fixing piece can be removed from the live circuit, making it easier to carry out wiring operation at the next location.

[0017] Furthermore, two limiting units are provided, and the two limiting units are respectively located on both sides of the wire clamp fixing part, and the limiting units include an installation box, a limiting block and a spring, the installation box is connected to the wire clamp fixing part, the limiting block is slidably matched with the installation box along a direction perpendicular to the wire clamp fixing part, the spring is connected between the limiting block and the installation box, and one end of the limiting block of the spring is located on the inner side of the wire clamp fixing part in a natural state.

[0018] Beneficial effect: In the process of installing the wire clamp on the inner side of the wire clamp fixing part in this scheme, the wire clamp will push the two limit blocks to move into the installation box, so that the wire clamp can smoothly pass through the limit blocks and be located between the two limit blocks. The wire clamp can be pressed by the spring of the limit block to prevent the wire clamp from falling. The limiting unit in this scheme has a simple way of fixing the wire clamp and does not require other auxiliary tools. The wire clamp can be locked and fixed when the wire clamp is inserted into the groove of the wire clamp fixing part.

[0019] When it is necessary to separate the wire clamp and the wire clamp fixing part on the live line, the wire clamp can be loosened by the wire clamp unlocking part, or the wire clamp insulating rod can be held and moved away from the wire clamp, so that the wire clamp will push the limit block to move inside the installation box so that the wire clamp can be smoothly separated from the wire clamp fixing part. This solution can effectively remove a live lap insulation operating tool in this solution, and the operation efficiency is more efficient.

[0020] Furthermore, the wire clamp fixing member includes a first side plate, a second side plate and a bottom plate, the first side plate and the second side plate are respectively connected to the two sides of the bottom plate, a U-shaped groove structure is formed between the first side plate, the second side plate and the bottom plate, and the first side plate and the second side plate are arranged to be inclined relative to each other.

[0021] Beneficial effect: The first side plate and the second side plate in the wire clamp fixing member of the present invention are arranged to be inclined relative to each other, so that the inclined surfaces of the first side plate and the second side plate can provide a tighter locking effect on the wire clamp, thereby ensuring the stability of the wire clamp during wiring and preventing it from falling off easily.

[0022] Furthermore, the sides of the two limit blocks facing each other are inclined surfaces that are inclined to each other, and the inclined surfaces of the two limit blocks are consistent with the inclination direction of the first side plate and the second side plate.

[0023] Beneficial effect: The two limit blocks in this solution can further improve the fixing effect of the wire clamp.

[0024] Furthermore, the end of the bottom plate with the largest width is arranged facing the wire clamp insulating rod; a guide groove is opened on the bottom plate along its length direction, and one end of the guide groove penetrates the end of the bottom plate with the smallest width;

[0025] A horizontal plate is connected to one side of the bottom plate, the wire clamp insulating rod is vertically connected to the horizontal plate, and the wire clamp insulating rod is hollow inside;

[0026] The wire clamp unlocking member includes a vertical rod, a horizontal rod and a pull wire, one end of the vertical rod is connected to the horizontal rod, the other end of the vertical rod is vertically slidably matched with the horizontal plate, the horizontal rod can extend into the guide groove, the pull wire is located in the wire clamp insulating rod, and one end of the pull wire is connected to the vertical rod, and the other end of the pull wire passes through one end of the wire clamp insulating rod away from the horizontal plate.

[0027] Beneficial effect: In this scheme, a guide groove is provided on the bottom plate. After the cross bar is extended into the guide groove, the vertical bar and the cross bar can be moved by pulling the wire in the wire clamp unlocking part of this scheme. In this way, when the wire clamp on the live line needs to be separated from the wire clamp fixing part, the wire clamp is pushed toward the end with the largest width of the bottom plate by pulling the wire, so that the gap between the wire clamp and the two sides of the lower frame fixing frame is increased. In this way, the resistance is smaller when the wire clamp is separated from the wire clamp fixing part by moving the wire clamp insulating rod, and the operation is easier. The whole process only requires one person to complete the installation of the wire clamp, the wiring connection and the removal of the tool.

[0028] Furthermore, it also includes a handle, one end of which is connected to the insulating rod of the wire clamp, a slider is provided inside the handle to slide along its axial direction, one end of the slider is fixedly connected to the slide rod, and a guide groove is provided on one side of the handle along its axial direction;

[0029] The upper and lower parts of the handle are respectively fixedly connected with an upper support block and a lower support block, a driving cylinder is rotatably matched between the upper support block and the lower support block, the top of the driving cylinder is rotatably matched with the upper support block, and the bottom of the driving cylinder is coaxially connected with a rotating rod, which passes through the lower support block and is rotatably matched with the lower support block;

[0030] The driving cylinder is hollow inside, and a spiral groove is provided on the circumference of the driving cylinder along its axial direction. The sliding rod on the sliding block passes through the guide groove and is located in the spiral groove.

[0031] Beneficial effect: The above scheme lacks safety in that the vertical movement of the vertical rod and the horizontal rod is driven by pulling the pull wire. Specifically, since the live-wire insulated operating rod of the present invention is used as a tool for connecting lines during 10kV live operations, it is sometimes necessary to operate in a high-altitude environment. If the vertical rod is moved by pulling the wire, this operation method will cause the hand to move away from the operating tool to pull the vertical rod to move. This method is likely to cause the operator's center of gravity to fall backwards, thereby easily causing the risk of personnel tipping over and creating a personal safety hazard.

[0032] When the pull wire is pulled by the present invention, the driving cylinder can be rotated by twisting the rotating rod without affecting the center of gravity of the operator. Since the driving cylinder has a spiral groove, the sliding rod and the sliding block can be driven to move along the guide groove when the driving cylinder rotates, thereby pulling the pull wire. The present invention is safer when pulling the pull wire, and the operator will not have a tendency to fall backwards, which effectively improves the safety of the operation.

[0033] Furthermore, the wire clamp insulating rod comprises a plurality of rod sections, and the plurality of rod sections are coaxially detachably connected.

[0034] Beneficial effects: With such a configuration, it is convenient to increase or decrease the rod body according to the actual operation height on site, thereby adjusting the operation height of the wire clamp insulating rod, which is more flexible and convenient to use and easy to carry; at the same time, the multiple sections of the rod body in this solution can be disassembled, avoiding the problem of heavy weight and inconvenience in operation when using a telescopic structure in the prior art. This solution only needs to increase the rod body according to the actual required operation height, and for the case of a shorter operation height, a corresponding number of rod bodies can be selected, and the weight of the entire tool will not be as heavy as when it is set as a telescopic rod structure. And the operation length range is wider, and the operation length can be adjusted according to actual needs, thereby expanding the operation distance range.

[0035] Furthermore, the handle is provided with anti-slip grooves, one end of the handle is connected to the insulating rod of the wire clamp, and the other end of the handle is connected to a hanging ring.

[0036] Beneficial effects: The anti-skid pattern on the handle can prevent slipping during operation, and the setting of the lifting ring is convenient for hanging or lifting when working on the pole.

[0037] The present invention can solve the problems of bulky original tools for live T-joint operation on low-voltage lines in distribution networks, limited operating distance, and inconvenience in carrying and storing due to fixed length.

[0038] This product uses the coordination of three parts: the wire clamp insulating rod, the wire clamp fixing part and the wire clamp unlocking part. It can complete the T-connected lead wire overlapping operation in a simple, lightweight and adjustable manner during live operations, solving the weak link of existing tools.

In this embodiment, the connecting tube 8 is integrally formed with the wire clamp fixing part 2 or welded and fixed, and the pressure rod 7 is inserted into the connecting tube 8.

[0055] Combination Figure 3 As shown, the wire clamp unlocking member in this embodiment includes an operating hook 10 and an operating hook insulating rod 11, and the operating hook 10 is connected to one end of the operating hook insulating rod 11 by a screw. Figure 1 As shown, an operating hole 901 is provided on the operating wrench 9, and the operating hook 10 can be hooked in the operating hole 901 to tighten or loosen the pressure rod 7. In this embodiment, the operating hook 10 is similar in shape to a fishing hook, which can be hooked in the operating hole 901 to make the operating wrench 9 turn the pressure rod 7, and can also tighten the bolt on the wire clamp.

[0056] In this embodiment, the wire clamp insulating rod 1 includes multiple rod sections, which are coaxially detachably connected. Specifically, the rod section is made of epoxy resin material with high strength and good insulation, with a diameter of 30-40mm, and the length of each rod section is 500mm. The multiple rod sections are coaxially threaded, or connected by rivets, screws, etc. The design of the multiple rod sections is easy to carry, and it is easy to increase or decrease the rod section according to the actual operating height requirements to change the length of the entire wire clamp insulating rod 1.

[0057] In this embodiment, a horizontal plate 5 is vertically connected to one side of the base plate 203, and the horizontal plate 5 is integrally formed or welded with the base plate 203. A connecting rod 4 is vertically connected to the horizontal plate 5, and the connecting rod 4 is integrally formed or welded with the horizontal plate 5. In this way, the connecting rod 4, the horizontal plate 5 and the wire clamp fixing part 2 are formed into one body, which is convenient for connection and disassembly with the wire clamp insulating rod 1. The connecting rod 4 is threadedly connected to the top rod body of the wire clamp insulating rod 1 or connected by rivets, screws, etc.

[0058] A live tapping insulation operating tool in the present embodiment also includes a handle 3, one end of which is connected to the wire clamp insulating rod 1, the handle 3 is made of rubber material, has a length of 150 mm, and is installed at the bottom end of the rod body. Anti-slip grooves 301 are provided on the rubber handle 3 to prevent slipping. The handle 3 is mainly used for the operator to hold the wire clamp insulating rod 1. In the present embodiment, a lifting ring 6 is connected to the other end of the handle 3, and the lifting ring 6 has a diameter of 50 mm to facilitate hanging and lifting when working on the pole.

[0059] The structure of the operating hook insulating rod 11 in this embodiment is consistent with that of the wire clamp insulating rod 1, and it also has a multi-section detachable rod body structure, and a handle 3 is connected to one end of the operating hook 10 insulating hook, which will not be described in detail here. The operating hook 10 is fixed to the top of the operating hook 10 insulating rod, and is shaped like a fishing hook. Its main function is to operate the bolt on the wire clamp to fix the connecting wire; at the same time, it is also used to operate the operating wrench on the wire clamp fixing part 2 to loosen the wire clamp located inside the wire clamp fixing part 2, so as to loosen and remove the wire clamp fixing part 2.

[0060] The specific implementation process is as follows:

[0061] In this embodiment, the wire clamp connected to the lead is installed through the "wire clamp fixing part 2", and the wire clamp is fixed in the U-shaped groove of the wire clamp fixing part 2; the length of the wire clamp insulating rod 1 is adjusted by increasing or decreasing the number of rod bodies, and then the wire clamp is installed on the live wire through the wire clamp insulating rod 1, and then the operating hook 10 is used to tighten the fixing bolt on the wire clamp to tighten the lead wire and the live line; the operating hook 10 is hooked on the operating hole 901 of the operating wrench 9; the operating wrench 9 is rotated to drive the pressure rod 7 to move, thereby loosening the wire clamp in the wire clamp fixing part 2, and finally the wire clamp fixing part 2 is removed to complete the lead lap work.

[0062] The specific operation process is as follows:

[0063] (1) The wire clamp is fixedly connected to the lead wire;

[0064] (2) The wire clamp is installed in the U-shaped groove of the wire clamp fixing member 2, and the pressure rod 7 is moved toward the wire clamp by rotating the operating wrench 9 on the side of the U-shaped groove to fix and tighten the wire clamp;

In addition, the multi-section structure of the wire clamp insulating rod in this embodiment solves the problems of the original operating rod being bulky, inconvenient to carry, and poor variability, and realizes the functions of adapting to different scenarios, rapid operation, portability, and convenient use.

[0070] Example 2

[0071] like Figure 4 and Figure 5 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, two limiting units are provided, and the two limiting units are respectively located on both sides of the wire clamp fixing part 2, and the limiting units include an installation box 13, a limiting block 14 and a spring 15. The installation box 13 is connected to the wire clamp fixing part 2. In this embodiment, the installation box 13 and the wire clamp fixing part 2 are integrally formed or welded, and the installation box 13 is located below the wire clamp fixing part 2.

[0072] In this embodiment, the first side plate 201 and the second side plate 202 are inclined to each other, so that the width of one end of the bottom plate 203 is the largest and the width of the other end is the smallest. In this embodiment, the end of the bottom plate 203 with the largest width is arranged toward the insulating rod 1 of the wire clamp.

[0073] The limit block 14 slides with the installation box 13 in a direction perpendicular to the wire clamp fixing piece 2 , and the spring 15 is connected between the limit block 14 and the installation box 13 . In the natural state, one end of the limit block 14 is located on the inner side of the wire clamp fixing piece 2 .

[0074] In this embodiment, the sides of the two limit blocks 14 facing each other are inclined surfaces that are inclined to each other, and the inclined surfaces of the two limit blocks 14 are consistent with the inclination direction of the first side plate 201 and the second side plate 202 .

[0075] A guide groove 12 is provided on the bottom plate 203 along its length direction, and one end of the guide groove 12 penetrates the end of the bottom plate 203 with the smallest width;

[0076] like Figure 5As shown, a horizontal plate 5 is connected to one side of the bottom plate 203, and the wire clamp insulating rod 1 is vertically connected to the horizontal plate 5. In this embodiment, the wire clamp insulating rod 1 is vertically connected to the horizontal plate 5 through a connecting rod 4. The wire clamp insulating rod 1 is hollow inside, which can reduce the weight of the wire clamp insulating rod 1 and facilitate the passage of the pull wire 20. The wire clamp unlocking member in this embodiment includes a vertical rod 17, a horizontal rod 18 and a pull wire 20. One end of the vertical rod 17 is connected to the horizontal rod 18, and the other end of the vertical rod 17 is vertically slidably matched with the horizontal plate 5. In this embodiment, a guide cylinder 16 is integrally connected to the top of the horizontal plate 5. The vertical rod 17 passes through the guide cylinder 16 and can slide axially along the guide cylinder 16. The horizontal rod 18 can extend into the guide groove 12 and slide in the guide groove 12. The pull wire 20 is located in the wire clamp insulating rod 1, and one end of the pull wire 20 is connected to the bottom end of the vertical rod 17, and the other end of the pull wire 20 passes through the end of the wire clamp insulating rod 1 away from the horizontal plate 5.

[0077] In the present embodiment, the handle 3 at the bottom of the insulating rod 1 of the wire clamp is hollow inside, and a guide rod 21 is fixedly connected inside the handle 3. A through hole is opened at the bottom of the handle 3, and the pull wire 20 passes through the guide rod 21 and passes through the through hole at the bottom of the handle 3 and is located outside. In the present embodiment, a pull ring 22 is connected to the bottom of the pull wire 20. The pull ring 22 is convenient for the hand to pull the pull ring 22 so that the pull wire 20 drives the vertical rod 17 and the horizontal rod 18 to move.

[0078] In this embodiment, when the wire clamp is installed in the U-shaped groove of the wire clamp fixing member 2, the wire clamp is inserted between the two limit blocks 14. During the insertion process, the wire clamp will push the two limit blocks 14 to move into the installation box 13, thereby ensuring the smooth insertion of the wire clamp. Since the first side plate 201 and the second side plate 202 on both sides of the wire clamp fixing member 2 in this embodiment are inclined to each other, the wire clamp fixing member 2 is narrow at the top and wide at the bottom, which is convenient for limiting the wire clamp, and the two limit blocks 14 clamp the wire clamp under the action of the spring 15, thereby completing the installation and fixation of the wire clamp. In this embodiment, there is no need to operate other auxiliary tools to twist the operating wrench 9 as in Example 1, and the operation of this embodiment is more efficient and convenient.

[0079] In this embodiment, the wire clamp unlocking piece is combined with the wire clamp fixing piece 2 and the wire clamp insulating rod 1. When the wire clamp is installed on the live wire, when the wire clamp installed in the U-shaped groove of the wire clamp fixing piece 2 needs to be separated from the wire clamp fixing piece 2, the pull wire 20 is pulled downward to move the vertical rod 17 and the horizontal rod 18 downward, so that the wire clamp in the wire clamp fixing piece 2 can be pushed downward, so that the distance between the wire clamp and the two sides of the wire clamp fixing piece 2 and the two limit blocks 14 becomes larger and larger, so that the wire clamp becomes looser. At this time, the wire clamp fixing piece 2 is moved away from the wire clamp by operating the wire clamp insulating rod 1, so as to achieve the effect of removing the entire operating tool.

[0080] In this embodiment, the installation and separation of the wire clamp on the wire clamp fixing member 2 can be made simpler and more convenient, and during operation, there is no need to carry the wire clamp unlocking member separately, which is more convenient to use and easy to carry, and the whole process only requires one person to complete the installation of the wire clamp, splicing of the lines and removal of the tools.

[0081] Example 3

[0082] like Figure 6 and Figure 7 The difference between this embodiment and embodiment 2 is that:

[0083] A slider 23 is provided inside the handle 3 for axial sliding engagement. The lower end of the pull wire 20 is connected to the slider 23. In this embodiment, a buckle is integrally connected to the top of the slider 23, and the pull wire 20 is knotted and fixed on the buckle.

[0084] One end of the slider 23 is fixedly connected to a slide rod 24 . In this embodiment, the slide rod 24 and the right end of the slider 23 are integrally formed. A guide groove 12 is provided on one side of the handle 3 along its axial direction.

[0085] The upper and lower parts of the handle 3 are respectively fixedly connected with an upper support block 25 and a lower support block 26. In this embodiment, the upper support block 25 and the lower support block 26 are screwed, adhesively fixed, or integrally formed. A driving cylinder 27 is rotatably engaged between the upper support block 25 and the lower support block 26. In this embodiment, the top of the driving cylinder 27 is rotatably engaged with the upper support block 25, and the bottom of the driving cylinder 27 is coaxially fixedly connected with a rotating rod 28. The rotating rod 28 passes through the lower support block 26 and is rotatably engaged with the lower support block 26. The rotating rod 28 is provided with an anti-slip pattern 301, and the rotating rod 28 is located in the lower middle part of the handle 3.

[0086] The driving cylinder 27 is hollow inside, and a spiral groove 271 is provided on the circumference of the driving cylinder 27 along its axial direction, and the slide bar 24 on the slider 23 passes through the guide groove 12 and is located in the spiral groove 271. When it is necessary to pull the pull wire 20 to drive the vertical rod 17 and the horizontal rod 18 to move downward and push the wire clamp located in the wire clamp fixing member 2 to move downward, the driving cylinder 27 is driven to rotate by rotating the rotating rod 28, so that the spiral groove 271 in the driving cylinder 27 drives the slide bar 24 and the slider 23 connected to the slide bar 24 to move downward, thereby pulling the pull wire 20 to move the vertical rod 17 and the horizontal rod 18 downward and push the wire clamp.

[0087] This solution is safer when removing the tool and separating the tool from the wire clamp, and can effectively avoid the safety risk of people losing their center of gravity and falling backwards during the process of pulling the pull wire 20.
