Description

Technical Field

[0001] This invention relates to the field of tools for dismantling and assembling diverter plates on power transmission line cable terminal towers, and particularly to a long-distance, convenient, electric device for dismantling and assembling diverter plates on power transmission cable terminal towers. Background Technology

[0002] During acceptance and maintenance of transmission line cable terminal (tension) towers, the current-carrying plates need to be opened for inspection. The purpose is to check for impurities and conductive grease inside the current-carrying plates, and to ensure proper connections. Impurities inside the current-carrying plates can cause abnormal heating, which, under prolonged high current conditions, can lead to melting and wire breakage. Currently, there are various types of transmission line cable terminal towers. On some towers (such as the SDLZD-24 tower type), the tension current-carrying plates are approximately 2.5 meters above the platform. Workers cannot reach the lower current-carrying plate bolts with a hand-held torque wrench, requiring the use of a rope ladder for disassembly and assembly. However, for this type of tower, the rope ladder is positioned high, and it needs to be installed for each phase of current-carrying plate disassembly and assembly, which is time-consuming, labor-intensive, and inefficient.

[0003] However, some tower-type diversion plates are far from the platform, and existing torque wrenches are too short to reach the bolts on the diversion plate. Most existing torque wrenches require manual rotation, which is time-consuming, labor-intensive, and difficult to install and remove. For example, a Chinese patent document, "A tool and method for disassembling and assembling a diversion plate on a power transmission cable terminal pole," publication number CN111300337A, discloses a method where the diversion plate on the power transmission cable terminal pole is connected to the jumper diversion pressure pipe using bolts and nuts. The disassembly and assembly tool includes a clamping frame, which includes a fixed frame and a movable frame that slides relative to the fixed frame. A push-opening screw is provided between the fixed frame and the movable frame to open them, and a return spring is provided to bring them closer together. The fixed frame has a first positioning sleeve that positions one end of the bolt. However, this solution does not solve the problem of difficult disassembly. Summary of the Invention

[0004] To address the problems of inconvenient, time-consuming, and labor-intensive disassembly and assembly in existing technologies, this invention provides a long-distance, convenient, electrically operated device for disassembling and assembling power transmission cable terminal pole guide plates, which can reduce operational difficulty, decrease operational steps, and improve operational efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A long-distance, portable, electrically operated device for installing and removing power transmission cable terminal pole guide plates includes: a first installation / removal tool for removing bolts from the guide plate; a second installation / removal tool for clamping suspension clamps; the first installation / removal tool is equipped with an electric spring, which has three working states: in the first working state, the spring is not under tension; in the second working state, the spring is under compressive elastic force; and in the third working state, the spring is under tensile elastic force. The first installation / removal tool is used to remove or install the fixing structure at the guide plate, and the second installation / removal tool is used to clamp the guide plate, reducing operational difficulty, steps, and efficiency. In the first working state, the electric spring is not energized and does not deform under elastic force; in the second working state, the electric spring is not energized and is stretched under elastic force; in the third working state, the electric spring is energized and stretched under elastic force, at which point the tensile force of the energized spring clamps the first installation / removal tool and the guide plate. The electric spring can be used to switch between multiple working states, thus enabling various actions during installation and removal.

[0007] Preferably, the first disassembly / assembly tool includes a power unit that provides driving force; a fixing unit connected to the power unit that clamps the bolts and the diversion plate; and a transmission unit between the power unit and the fixing unit that transmits the driving force from the power unit to the fixing unit. Providing power remotely via the power unit eliminates the need for operators to climb to heights for manual operation, improving convenience and safety. Fixing and disassembling the bolts at the diversion plate via the fixing unit improves operational efficiency, avoiding the need to disassemble and reassemble the bolts while clamping the diversion plate. The transmission unit transmits power from bottom to top, freeing the operation from spatial limitations, and the distance of the power source from power transmission lines enhances safety.

[0008] Preferably, the fixing part includes a first clamping member and a second clamping member arranged symmetrically. The first clamping member and the second clamping member are respectively provided with opposite grooves. A spring is fixedly connected between the first clamping member and the second clamping member. The first clamping member is connected to a movable pulley. The first clamping member and the second clamping member are connected by a plate-shaped member. The upper end face of the plate-shaped member is provided with a sliding groove. The first clamping member is located in the sliding groove, and the spring is located in the sliding groove. One end of the spring is fixedly connected to the side wall of the sliding groove, and the other end of the spring is fixedly connected to the side wall of the first clamping member. The first clamping member extends upward from the upper end face of the plate-shaped member, and the second clamping member is located above the plate-shaped member. The first clamping member and the second clamping member are respectively located at both ends of the plate-shaped member. The grooves are all located above the plate-shaped member. The groove depth of the first clamping member is less than the groove depth of the second clamping member. A magnet is provided inside the groove of the first clamping member. The side of the first clamping member away from the second clamping member is fixedly connected to the transmission part. The spring force can control the first and second clamping parts to work together to clamp the bolt, thereby controlling the rotation to tighten or loosen the bolt.

[0009] Preferably, the movable pulley section includes a set of vertically arranged movable pulleys, with a steel wire rope connected to one end of the movable pulley set, and a hook connected to the other end of the steel wire rope. The movable pulleys are located on the side of the plate-shaped member, away from the second clamping member and closer to the first clamping member. The movable pulley set includes multiple small pulleys arranged vertically. A steel wire rope is provided on the lower end face of the plate-shaped member. One end of the steel wire rope is fixedly connected to the side end face of the first clamping member and wound in the movable pulley set. The steel wire rope passes through the lower end face of the plate-shaped member and connects to the transmission part and the hook, which is located on the outer wall of the side end face of the transmission part. The movable pulleys can control the stretching and shortening of the spring, ensuring the clamping force between the first and second clamping members under the spring force.

[0010] Preferably, the transmission unit includes a steering gear set, which comprises two meshing gears with perpendicular axes. One end of the steering gear set is connected to a first clamping member, and the other end is connected to an extension rod, which is connected to a power unit. The transmission unit includes a steering shaft, the end of which is fixedly connected to a second clamping member. A first steering gear is mounted on the steering shaft, and a second steering gear is mounted at the end of the extension rod. The second and third steering gears mesh together, forming a steering gear set. The axes of the first and second steering gears are perpendicular to each other. An operating lever extends downward and connects to the power unit. A second housing is provided on the outside of the operating lever, and a first housing is provided on the outside of the steering gear set. The outer end wall of the first housing abuts against the end face of the second clamping member away from the first clamping member. The lower end face of the first housing is connected to the upper end face of the plate-like member, and the lower side of the first housing is located at the lower end face of the plate-like member and connected to the second housing. The power required to tighten the bolts is converted by bevel gears, which facilitates operation and transmission. At the same time, the precision brought by gear transmission can control the start and stop in time during the bolt installation and removal process, avoiding wear on the device caused by installation and removal. Remote operation can be achieved by rotating the extension rod. Meanwhile, the first and second outer shells can prevent debris brought by airflow from above from entering.

[0011] Preferably, the second disassembly / assembly tool includes an operating lever with a fixed operating clamp at its top for clamping the drainage plate. The operating lever is the same length as the extension lever, allowing the drainage plate to be clamped in advance to prevent displacement of the drainage plate during disassembly / assembly and avoid errors. The fixed operating clamp contains a small spring with clamping plates at both ends. By clamping the drainage plate at non-disassembly / assembly locations using the fixed operating clamp, disassembly / assembly and clamping can be performed separately.

[0012] Preferably, the power unit includes an electric torque gun connected to an extension rod. The electric torque gun provides rotational power and is fixedly connected to the extension rod. The second housing has a wide-diameter opening at its end, within which the electric torque gun is located. This design allows for power delivery via the electric torque gun, providing portability and easy control based on actual conditions.

[0013] Preferably, the electric spring is connected to the power unit. The electric spring contracts upon being energized, and its two ends are connected to the bottoms of the first and second clamping members, respectively. The electric spring is connected to a power source located within the power unit. A power touch switch is connected to the hook, with its two ends connected to the power source and the electric spring, respectively. The hook is rotatably connected to the outer end face of the second housing. When the hook contacts the power touch switch, the power touch switch charges the electric spring. This allows the spring to automatically tighten by charging, and the shortened distance and increased resistance after charging enable immediate clamping of the guide plate.

[0014] Preferably, the hook is connected to a planetary gear set, which is connected to an extension rod. The hook is located on the sun gear within the planetary gear set. The planetary gears in the planetary gear set are fixedly connected to the extension rod. Spacing-out blank rims are provided between the teeth of the sun gear, with multiple teeth located between these blank rims. The diameter of each blank rim is the same as the root circle diameter of the teeth. The axial center lines of the planetary gears and the sun gear are arranged perpendicularly, enabling the movable pulley to be released while driving the second clamping member, and the spring to be tightened while stopping the drive of the second clamping member.

[0015] The present invention has the following advantages:

[0016] (1) To enable the maintenance of the cable terminal tower diversion plate, which is convenient for operators, reduces the difficulty of operation, reduces the intensity of operation, and facilitates the timely detection of diversion plate defects and eliminates power outage accidents caused by diversion plate melting; (2) By providing power remotely through the power unit, the operator can avoid climbing to a high place to perform manual operation, which improves convenience and safety; by fixing the bolts at the diversion plate through the fixing part and realizing the disassembly and assembly operation, the operation efficiency can be improved, and the bolt disassembly and assembly can be avoided when clamping the diversion plate; by transmitting power from bottom to top through the transmission part, the operation process is not limited by space, and the power source is far away from the transmission line, which is safer; (3) It can loosen the moving pulley while driving the second clamping part, and tighten the spring while stopping the driving of the second clamping part, so as to realize automatic bolt removal and clamping of the diversion plate.

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, in a preferred embodiment, the present invention discloses a long-distance, convenient, electrically operated, detachable power transmission cable terminal pole guide plate device, comprising:

[0026] A long-distance, portable, electrically operated device for assembling and disassembling power transmission cable terminal pole guide plates includes: a first disassembly and assembly tool 11, used for disassembling and assembling bolts 3 of the guide plate; the first disassembly and assembly tool 11 is used to disassemble or install the fixing structure at the guide plate. In use, the first disassembly and assembly tool 11 is used to disassemble and assemble the bolts 3 at the guide plate, and simultaneously clamps the disassembled guide plate.

[0027] like Figure 2-3 As shown, the first disassembly / assembly tool 1 includes a power unit that provides driving force; the power unit includes an electric torque gun 5, which is connected to an extension rod. The electric torque gun 5 provides rotational power and is fixedly connected to the extension rod. The second housing 15 has a wide-neck opening at its end, and the electric torque gun 5 is located within this opening. In use, the electric torque gun 5 is inserted into the transmission unit, and the power output direction of the electric torque gun 5 is the same as the output direction of the transmission unit.

[0028] The power unit is connected to a fixing part, which is used to clamp the bolt 3 and the diverter plate. The fixing part includes a first clamping member 6 and a second clamping member 7 arranged symmetrically. The first clamping member 6 and the second clamping member 7 are respectively provided with opposite grooves 16. A spring is fixedly connected between the first clamping member 6 and the second clamping member 7. The first clamping member 6 is connected to a movable pulley part. The first clamping member 6 and the second clamping member 7 are connected by a plate-shaped member. The upper surface of the plate-shaped member has a groove. The first clamping member 6 is located within the groove, and a spring is also located within the groove. One end of the spring is fixedly connected to the side wall of the groove, and the other end of the spring is fixedly connected to the side wall of the first clamping member 6. The first clamping member 6 extends upwards from the upper surface of the plate-shaped member, and the second clamping member 7 is located above the plate-shaped member. The first clamping member 6 and the second clamping member 7 are located at opposite ends of the plate-shaped member. Grooves 16 are located above the plate-shaped member. The depth of the groove 16 in the first clamping member 6 is less than the depth of the groove 16 in the second clamping member 7. A magnet 8 is provided inside the groove 16 of the first clamping member 6. The side of the first clamping member 6 away from the second clamping member 7 is fixedly connected to a transmission part. The spring force can control the combined action of the first clamping member 6 and the second clamping member 7 to clamp the bolt 3, thereby controlling the rotation to tighten or loosen it.

[0029] In use, the first clamping member 6 and the second clamping member 7 are two U-shaped parts arranged in opposite directions. The first clamping member 6 contains a bolt 3, and the second clamping member 7 contains a nut. The head of the bolt 3 is attracted by the magnet 8 inside the first clamping member 6, and the bolt 3 is snapped into the first clamping member 6. After the head of the bolt 3 is attracted, the bottom surface is flush with the edge of the first clamping member 6. The first clamping member 6 moves in the groove inside the plate-shaped part. The nut is snapped into the second clamping member 7. After the transmission part drives the second clamping member 7 to rotate, the second clamping member 7 drives the nut to rotate and move along the thread direction of the bolt 3. During disassembly, the nut moves in the direction of falling off the end of the bolt 3. However, the back of the second clamping member 7 abuts against the transmission part. Therefore, the bolt 3 drives the first clamping member 6 to slide in the groove and move away from the second clamping member 7 through the reverse force. At the same time, the spring between the first clamping member 6 and the second clamping member 7 is stretched. Thus, the two adjacent diverting plates are separated, completing the separation of the diverting plates.

[0030] The movable pulley section includes a set of vertically arranged movable pulleys. The other end of the movable pulley group 11 is connected to a steel wire rope 13, and the other end of the steel wire rope 13 is connected to a hook 14. The movable pulleys are located on the side of the plate-shaped member away from the second clamping member 7 and close to the first clamping member 6. The movable pulley group 11 includes multiple small pulleys arranged vertically. The lower end face of the plate-shaped member is provided with a steel wire rope 13. One end of the steel wire rope 13 is fixedly connected to the side end face of the first clamping member 6 and wound in the movable pulley group 11. The steel wire rope 13 passes through the lower end face of the plate-shaped member and connects to the transmission part and the hook 14. The hook 14 is located on the outer wall of the side end face of the transmission part.

[0031] In use, when removing bolt 3, the wire rope 13 is wound around hook 14. The wire rope 13 changes the direction of the tension and increases the magnitude of the tension through the movable pulley. The wire rope 13 counteracts the spring force and drives the first clamping member 6 to move. The wire rope 13 drives the first clamping member 6 to overcome the spring force and move away from the second clamping member 7. When the first disassembly tool 1 clamps the diversion plate, the larger wire rope 13 on hook 14 is unwound and releases the other end of the first clamping member 6. The first clamping member 6 is no longer subjected to the tension generated by the wire rope 13 through the movable pulley. At this time, the spring is stretched and needs to reset under the action of the tension. The first clamping member 6 is driven by the tension of the spring to move towards the first clamping member 6, so that the first clamping member 6 and the second clamping member 7 clamp the diversion plate.

[0032] A transmission section is provided between the power unit and the fixed unit to transmit the driving force of the power unit to the fixed unit. The transmission section includes a steering gear set 9, which includes two meshing gears with perpendicular axes. One end of the steering gear set 9 is connected to the first clamping member 6, and the other end is connected to an extension rod, which is connected to the power unit. The transmission section includes a steering shaft 17, the end of which is fixedly connected to the second clamping member 7. A first steering gear is provided on the steering shaft 17, and a second steering gear is provided at the end of the extension rod. The second steering gear and the second steering gear form a meshing engagement. The first steering gear and the second steering gear set 9 form a steering gear set 9, and the axes of the first steering gear and the second steering gear are perpendicular to each other. An operating lever extends downward and connects to the power unit. A second housing 15 is provided on the outside of the operating lever, and a first housing is provided on the outside of the steering gear set 9. The outer end wall of the first housing abuts against the end face of the second clamping member 7 away from the first clamping member 6. The lower end face of the first housing is connected to the upper end face of the plate-shaped member, and the lower side of the first housing is located at the lower end face of the plate-shaped member and connected to the second housing 15. The power required to tighten the bolt 3 is converted by bevel gears, which facilitates operation and transmission. At the same time, the precision brought by gear transmission can control the start and stop in time during the disassembly and assembly of the bolt 3, avoiding wear of the device caused by disassembly and assembly. Remote operation can be achieved by rotating the extension rod. Meanwhile, the first and second outer shells 15 can prevent debris brought by airflow from high places from entering them.

[0033] When in use, the extension rod is adjusted according to its length. After the power is provided by the power unit, the extension rod rotates as a whole. The power is then transmitted through the second steering gear at the end. The end of the steering shaft 17 passes through the first housing and extends outward a certain length away from the side of the second clamping member 7. The rotation of the second steering gear drives the first steering gear to rotate, which in turn drives the steering shaft 17 and the second clamping member 7 to rotate, thereby tightening the bolt 3 through the second clamping member 7.

[0034] like Figure 1As shown, the device includes a second disassembly / assembly tool 2, which is used to clamp the suspension clamp 44. The second disassembly / assembly tool 2 includes an operating rod with a fixed operating clamp 10 at its top. The fixed operating clamp 10 is used to clamp the drainage plate. The length of the operating rod is the same as the extension rod. The drainage plate can be clamped in advance using the operating rod to avoid errors caused by displacement of the drainage plate during disassembly / assembly. The fixed operating clamp 10 has a small spring inside, with clamping plates at both ends. The fixed operating clamp 10 clamps the drainage plate at non-disassembly / assembly locations, allowing disassembly / assembly and clamping to be performed separately. The drainage plate is then clamped using the second disassembly / assembly tool 2.

[0035] In use, the second disassembly and assembly tool 2 is used to clamp one diversion plate and its suspension clamp 44, without clamping the other diversion plate. After the bolt 3 is removed by the first disassembly and assembly tool 1, the second disassembly and assembly tool 2 is used to remove the clamped diversion plate, allowing the first disassembly and assembly tool 1 to clamp the other diversion plate.

[0036] The invention of this device enables the inspection and maintenance of the diversion plates of cable terminal towers, and can promptly detect and eliminate defects in the diversion plates (such as the presence of impurities like yellow mud inside the diversion plate causing abnormal heating during diversion), thus preventing power outages caused by diversion plate meltdown. Taking one diversion plate meltdown accident per year as an example, the emergency repair takes an average of 8 hours. The average load of 110kV is generally no less than 50,000 kW, the average retail price is 0.794 yuan / kWh, and the average grid connection price is 0.46 yuan / kWh. Theoretically, the economic benefits that can be generated are 5*8*(0.794-0.46)=133,600 yuan.

[0037] like Figure 4As shown, in the second embodiment, the spring is an electric spring 12, which is connected to the power unit. The electric spring 12 contracts upon being energized, and its two ends are connected to the bottoms of the first clamping member 6 and the second clamping member 7, respectively. The electric spring 12 has three operating states: in the first operating state, the spring is not under tension; in the second operating state, the spring is under compressive force; and in the third operating state, the spring is under tensile force. The electric spring 12 is connected to a power source located in the power unit. A hook 14 is connected to a power contact switch 18, whose two ends are connected to the power source and the electric spring 12, respectively. The hook 14 is rotatably connected to the outer end face of the second housing 15. When the hook 14 contacts the power contact switch 18, the power contact switch 18 charges the electric spring 12. The hook 14 is connected to a planetary gear set 20, which is connected to an extension rod. The hook 14 is located on the sun gear 19 of the planetary gear set 20. Planetary gear set 20 is fixedly connected to the extension rod. The sun gear 19 has spaced blank rims between its teeth, with multiple teeth located between these blank rims. The diameter of each blank rim is the same as the root circle diameter of the teeth. The axial center lines of planetary gear set 20 and sun gear 19 are arranged perpendicularly. In the first working state, the electric spring 12 is not energized and does not deform under elastic force. In the second working state, the electric spring 12 is not energized and is stretched under elastic force. In the third working state, the electric spring 12 is energized and stretched under elastic force; at this time, the tensile force of the energized spring 12 clamps the first disassembly / assembly tool 1 with the guide plate.

[0038] In use, after starting the power unit, the power unit drives the extension shaft to rotate, which in turn drives the planetary gear set 20 to rotate. The planetary gear set 20 then drives the sun gear 19 to rotate. Here, planetary gear set 20 and sun gear 19 refer to the number of teeth, with the sun gear 19 having more teeth than the planetary gear set 20. The rotation of the sun gear 19 drives the hook 14 to rotate. Due to the differential speed effect, when the nut moves towards the direction of the detached bolt 3, the planetary gear set 20 also drives the hook 14 to rotate via the sun gear 19, winding the wire rope 13 around the hook 14. The wire rope 13 then pulls the spring. After the nut separates from the bolt 3, and the bolt 3 comes off the two guide plates, the sun gear 19 rotates to the empty wheel side, corresponding to the planetary gear set 20. At this moment, the hook 14 simultaneously comes into contact with the power contact switch 18. The power contact switch 18 receives the compression signal and energizes the power supply to the electric spring 12. The electric spring 12 then moves from the second working state to the first working state. The three working states transition as follows: When the electric spring 12 is energized, it contracts, causing the first clamping member 6 to move closer to the second clamping member 7. Simultaneously, the wire rope 13 drives the hook 14 and the sun gear 19 to reverse, releasing the wire rope 13. The electric spring 12 directly changes from the second working state to the third working state without going through the first working state. The tension generated by the energized electric spring 12 pulls the first clamping member 6 towards the diverter plate, and after stopping the movement, it receives the compressive stress from the first clamping member 6 towards the second clamping member 7. After the first clamping member 6 and the second clamping member 7 clamp together, the blank wheel edge ends the re-engagement of the planetary gear set 20 and the sun gear 19, and the reverse rotation stops. This automatically and immediately clamps the diverter plate, avoiding delayed operation.

[0039] In the third embodiment, the power unit includes a small motor with a motor switch. The output shaft of the small motor and the extension rod are arranged coaxially, and the motor switch is connected to a power source. The extension rod can be driven to rotate by the motor, thereby controlling the rotation of the second clamping member 7 by providing torsional force, thus enabling the installation and removal of the bolt 3 at the diversion plate.

[0040] In the fourth embodiment, the second disassembly tool 2 is provided with a pull rope, which is connected to a push plate. The push plate is rotatably connected to the side end face of the fixed operating clamp 10, and the push plate abuts against the middle of the two diversion plates. The pull rope is connected to the first clamping member 6 and is used to pull up the push plate. After the bolt 3 of the diversion plate is removed, the pull rope moves with the first clamping member 6 and just drives the push plate to move between the two diversion plates to remove the debris between the two diversion plates.

[0041] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
