Description

Technical Field

[0001] This invention relates to the field of live-line maintenance tools for power transmission lines, and in particular to a wire clamp installation device and its installation method. Background Technology

[0002] Currently, taking the State Grid Yantai Power Supply Company's statistics over the past three years as an example, there have been 21 instances of live-line treatment for overheating defects in the current-carrying plates. Adding to this the 7 applications for treatment that could not be handled, the annual average demand for live-line treatment is 9.3 times. The provincial company comprises 17 municipal companies, with an annual average demand for live-line treatment of overheating defects in current-carrying plates of 158.1 times. When treating overheating defects in current-carrying plates using equipotential bonding, a double-amp clamp is typically used to bypass a steel-cored aluminum stranded wire of the same diameter as the current-carrying wire. This serves to divert the current, reducing the current flowing through the equipment clamp and thus lowering its temperature.

[0003] Common installation methods: 1. Use of the Ampu wire clip gun. The original Ampu wire clip mounting device was an explosive type wire clip gun, which was prohibited by the state because it required the filling of explosives inside the barrel.

[0004] II. Hammer Installation. During the initial installation of the bypass drain line, equipotential bonding personnel must independently complete the installation and climbing of the insulated rope ladder and insulated flat ladder. Workers wear heavy shielding suits, with two layers of gloves—one cotton glove and one shielding suit glove—and use a hand hammer to hammer the Ampere clamps for installation. This method is physically demanding; after several hammer blows, the forearms swell, affecting subsequent safety when removing the electric field. Because of the two layers of gloves, the hammer is highly susceptible to flying out, posing a significant danger. Furthermore, safety regulations prohibit hammering while wearing gloves, making this action a violation of safety regulations.

[0005] In response to the aforementioned technologies, there is an urgent need to research a set of Amp clamp installation devices. When operators encounter overheating defects in the drain plate, an installation device that allows for equipotential installation of Amp clamps and the addition of bypass leads can achieve the goal of safe and rapid installation. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a wire clamp installation device and its installation method. It also provides an equipotential bonding tool for addressing overheating defects in current-carrying plates, offering convenient installation, improved efficiency in live-line work, reduced workload, and lower safety risks for workers. Specifically, it is a dedicated tool and method for installing Amp wire clamps. This process reduces the workload of workers, increases safety and efficiency, and ensures operational safety.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A wire clamp mounting device includes a limiting device and a power device. The limiting device includes a limiting body, one end of which is connected to a limiting cavity plate. A limiting cavity is formed in the limiting cavity plate. The limiting body is placed in the limiting cavity and slidably connected to the limiting cavity plate. The limiting cavity plate is provided with a limiting post and a limiting linkage operating rod. An end limiting plate is connected to the end of the limiting cavity plate away from the limiting body. The power unit includes a hydraulic cylinder, which is equipped with a hydraulic operating lever and a hydraulic knob. One end of the hydraulic cylinder is connected to a hydraulic column, and the hydraulic cylinder is connected to the end of the limiting body away from the limiting cavity plate.

[0008] Furthermore, the hydraulic cylinder has an external thread structure on its outer side, a connecting ring is provided at the end of the limiting body away from the limiting cavity plate, and an internal thread structure is provided on the inner side of the connecting ring. The external thread structure and the internal thread structure are compatible with each other, and the hydraulic column is placed inside the connecting ring.

[0009] Furthermore, the end limiting plate includes a boundary limiting plate and a support plate. Both the boundary limiting plate and the support plate are provided with a number of connecting holes, which are connected to the limiting cavity plate by means of flat-head pins.

[0010] Furthermore, the limiting linkage operating rod is connected to a pressing button and a compression spring structure, and the limiting linkage operating rod is connected to the limiting cavity plate through a combination of the limiting post, the pressing button, and the compression spring structure.

[0011] Furthermore, a number of limiting holes are provided on one side of the limiting body. The limiting post is pressed into the limiting hole by the reset of the compression spring structure. The limiting post connects the limiting body and the limiting cavity plate. The limiting post completes the locking and fixing of the limiting body and the limiting cavity plate.

[0012] Furthermore, a fall protection strap is connected to the outside of the hydraulic cylinder.

[0013] A method for installing a wire clamp mounting device includes the following steps: Step 1: First, place the branch line to be connected inside the Amp clamp housing. Then, hang the Amp clamp housing and the lead wire together on the conductor. Insert the Amp clamp tongue between the conductor and the lead wire. Then, fasten the clamp installation device onto the Amp clamp and fix the anti-fall bandage to the conductor. Step 2: Use fasteners to fix the support plate to the lower end of the boundary limiting plate to form a closed space around it, and anchor and limit the wire and lead wire. Step 3: Press the button inward to activate the limit linkage operating lever, causing the limit post fixed to it to disengage from the limit hole on the limit body. At the same time, push the hydraulic operating lever back and forth to bring the fixed limit body and hydraulic post close to the Anpu wire clamp tongue plate, so that the Anpu wire clamp is clamped and limited by the hydraulic post and the boundary limit plate at the front and back respectively. Release the limit linkage operating lever and pull the hydraulic operating lever back and forth again to confirm that the limit posts on both sides are fixed in the limit hole. Step 4: Turn the hydraulic knob to the start position, manually operate the hydraulic operating lever to push the hydraulic column out, push the Ampu clamp tongue plate of the Ampu clamp to move inside the Ampu clamp housing, and clamp the wire and lead wire together with the Ampu clamp. Step 5: When the hydraulic column reaches its maximum single stroke, the hydraulic control lever will stop pressing. Turn the hydraulic knob to the off position to reset the hydraulic column. Step Six: Repeat Steps Two and Three until the Ampu clamp is installed in place. When you feel obvious effort during pressing and the hydraulic column feed is not obvious, it is installed in place.

[0014] In summary, compared with the prior art, the beneficial effects of the above technical solution are: This invention provides an equipotential bonding tool for addressing overheating defects in current-carrying plates, which is easy to install, improves the efficiency of live-line work, reduces work intensity and worker safety risks, specifically a dedicated tool and method for installing Ampere clamps. By completing the installation of Ampere clamps, the labor intensity of workers is reduced, the safety factor and work efficiency are improved, and work safety is ensured.

[0017] The principles and features of the present invention are described below with reference to all the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0018] This invention discloses a wire clamp mounting device and its mounting method.

[0019] Reference Figures 1 to 9 As shown, a wire clamp installation device includes a limiting device 1 and a power device 2. The limiting device 1 includes a limiting body 11. One end of the limiting body 11 is connected to a limiting cavity plate 12. A limiting cavity is formed in the limiting cavity plate 12. The limiting body 11 is placed in the limiting cavity and slidably connected to the limiting cavity plate 12. The limiting cavity plate 12 is provided with a limiting post 13 and a limiting linkage operating rod 14. An end limiting plate is connected to the end of the limiting cavity plate 12 away from the limiting body 11.

[0020] The end-positioning plate includes a boundary limiting plate 15 and a support plate 16. Both the boundary limiting plate 15 and the support plate 16 have several connecting holes. In this embodiment, the connecting holes include a left connecting hole 161 and a right connecting hole 162. These connecting holes are connected to the limiting cavity plate 12 via flat-head pins. In the end-positioning plate, the boundary limiting plate 15 and the support plate 16 limit the end of the Amp wire clamp housing and form a closed space to anchor the conductor and lead wire, preventing them from detaching. It should be noted that in this embodiment, one of the connecting holes is pre-fixed using a flat-head pin, allowing the support plate 16 to rotate. During operation, a wing bolt is used to thread and fix the other connecting hole.

[0021] The internal space of the limiting cavity in the limiting device 1 provides a track space for the free sliding of the limiting body 11. The limiting body 11 and the limiting cavity are connected and tightened by a fastening spring, and automatic reset is achieved within the track space.

[0022] The power unit 2 includes a hydraulic cylinder 21, which is equipped with a hydraulic operating lever 22 and a hydraulic knob 24. One end of the hydraulic cylinder 21 is connected to a hydraulic column 23, and the hydraulic cylinder 21 is connected to the end of the limiting body 11 away from the limiting cavity plate 12.

[0023] like Figure 7 As shown, the hydraulic cylinder 21 has an external thread structure on its outer side, and the limiting body 11 has a connecting ring 112 at one end away from the limiting cavity plate 12. The connecting ring 112 has an internal thread structure on its inner side, and the hydraulic column 23 is placed inside the connecting ring 112. The external thread structure and the internal thread structure are compatible with each other.

[0024] The power unit 2 is connected to the limit device 1 by its external thread structure, thereby achieving a tight connection between the power unit 2 and the limit device 1, and thus enabling the power of the hydraulic column 23 to be transmitted from the power unit 2 to the limit device 1.

[0025] like Figure 8 As shown, the cylindrical structure of the limiting body 11 ( Figure 8 (As shown) The front end of the Amp clamp, namely the Amp clamp tongue plate, is pressed against the clamp. The boundary limiting plate 15 and the support plate 16 limit the end of the Amp clamp, namely the Amp clamp housing. The two parts work together to clamp and limit the Amp clamp.

[0026] The limit linkage operation rod 14 is connected to a press button 141 and a compression spring structure 142. The limit linkage operation rod 14 is connected to the limit cavity plate 12 through the combination of the limit post 13, the press button 141 and the compression spring structure 142.

[0027] A plurality of limiting holes 111 are provided on one side of the limiting body 11. The limiting post 13 is pressed into the limiting hole 111 by the reset of the compression spring structure 142. The limiting post 13 connects the limiting body 11 and the limiting cavity plate 12, and the limiting post 13 completes the locking and fixing of the limiting body 11 and the limiting cavity plate 12. In the locking structure of the limiting post 13, the limiting linkage operating rod 14 is fixedly connected to the limiting post 13. The limiting post 13 achieves the fixing and limiting function of the limiting body 11 and the limiting cavity plate 12 by the reset of the compression spring structure 142.

[0028] A fall arrestor strap 25 is connected to the outside of the hydraulic cylinder 21. The fall arrestor strap 25 is fixed to the end of the hydraulic operating lever 22 in the power unit 2, which serves as a fall arrestor.

[0029] The implementation principle of a wire clamp mounting device according to an embodiment of the present invention is as follows: Reference Figures 1 to 6As shown, a wire clamp installation device consists of a limiting device 1 and a power device 2. The limiting device 1 includes six components: a limiting body 11, a limiting cavity plate 12, a limiting post 13, a limiting linkage operating rod 14, a boundary limiting plate 15, and a support plate 16.

[0030] The power unit 2 comprises four parts: a hydraulic cylinder 21, a hydraulic operating lever 22, a hydraulic cylinder 23, and a hydraulic knob 24. Additionally, a fall protection strap 25 is fixed to the end of the hydraulic operating lever 22.

[0031] The end limiting plate consists of a boundary limiting plate 15 and a support plate 16. The boundary limiting plate 15 and the support plate 16 are respectively provided with a left connecting hole 161 and a right connecting hole 162. The support plate 16 is connected to the boundary limiting plate 15 via a flat-head pin, enabling opening and closing movement around the flat-head pin. After the device is installed in place, the boundary limiting plate 15 and the support plate 16 are connected in a closed loop by tightening the wing bolt connected to the right connecting hole 162.

[0032] The locking structure of the limiting post 13 consists of a limiting body 11, a limiting post 13, and a limiting linkage operating rod 14. The limiting body 11 has equally spaced limiting holes 111 on both sides. The limiting post 13 and the limiting linkage operating rod 14 are fixed together by fastening bolts. On the opposite side of the limiting post 13, the pressing button 141 and the limiting linkage operating rod 14 are directly integrated. The pressing button 141 has a compression spring structure 142 inside. By resetting the compression spring structure 142, the limiting post 13 enters the limiting hole 111, thus achieving the locking and fixing between the limiting body 11 and the limiting cavity. Conversely, by pressing the pressing button 141 and compressing the compression spring structure 142, the limiting post 13 on the opposite side can move away from the limiting hole 111, thus allowing the limiting body 11 to move freely within the limiting cavity.

[0033] The internal space of the limiting cavity in the limiting device 1 provides a track space for the free sliding of the limiting body 11. The limiting body 11 and the limiting cavity are connected and tightened by a tension spring. When the limiting post 13 is disengaged from the limiting hole 111, the limiting body 11 automatically resets in the track space.

[0034] The limiting post 13 clamping structure presses the front end of the Amp clamp, i.e. the Amp clamp tongue plate, against it, while the end limiting plate limits the end of the Amp clamp, i.e. the Amp clamp housing. The two parts work together to clamp and limit the Amp clamp.

[0035] The power unit 2 is connected to the limit device 1 by its external thread structure, thereby achieving a tight connection between the power unit 2 and the limit device 1, and thus enabling the power of the hydraulic column 23 to be transmitted from the power unit 2 to the limit device 1.

[0036] The end of the hydraulic operating lever 22 in the power unit 2 is fixed with a fall protection strap 25, which provides fall protection by binding the overhead power line.

[0037] Reference Figures 1 to 6 As shown, an installation method for a wire clamp mounting device includes the following steps: Step 1: First, place the branch line to be connected inside the Amp clamp housing. Then, hang the Amp clamp housing and the lead wire together on the conductor. Insert the Amp clamp tongue plate between the conductor and the lead wire. Then, fasten the clamp installation device onto the Amp clamp and fix the anti-fall bandage 25 to the conductor. Step 2: Use fasteners to fix the support plate 16 to the lower end of the boundary limiting plate 15 to form a closed space around the wire and limit the wire. Step 3: Press the button 141 inward to activate the limit linkage operating lever 14, causing the limit post 13 fixed thereon to disengage from the limit hole 111 on the limit body 11. At the same time, push the hydraulic operating lever 22 back and forth to bring the fixedly connected limit body 11 and hydraulic post 23 close to the Anpu wire clamp tongue plate, so that the Anpu wire clamp is clamped and limited by the hydraulic post 23 and the boundary limit plate 15 at the front and back respectively. Release the limit linkage operating lever 14, and pull the hydraulic operating lever 22 back and forth again to confirm that the limit posts 13 on both sides are fixed in the limit hole 111. It should be noted that the fixed connection is between the limit body 11 and the hydraulic cylinder 21 with an external thread structure. The hydraulic post 23 is in the hydraulic cylinder 21. When the hydraulic operating lever 22 is pressed up and down, the hydraulic post 23 can be pushed out of the hydraulic cylinder 23 by the hydraulic action. Step 4: Turn the hydraulic knob 24 to the start position ("ON" position), manually operate the hydraulic operating lever 22 to push out the hydraulic column 23, push the Ampu clamp tongue plate of the Ampu clamp to move inside the Ampu clamp housing, and clamp the wire and lead wire together with the Ampu clamp. Step 5: When the hydraulic cylinder 23 is fed to the maximum stroke in a single operation, the hydraulic operating lever 22 can no longer be pressed down. Turn the hydraulic knob 24 to the "OFF" position to reset the hydraulic cylinder 23. Step 6: Repeat steps 2 and 3 until the Ampu clamp is installed in place. When you feel obvious effort during pressing and the hydraulic column 23 does not feed significantly, it is installed in place.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
