Description

Technical Field

[0001] This invention belongs to the field of power engineering maintenance equipment, specifically relating to a power distribution line maintenance device. Background Technology

[0002] As the "last mile" of the power system facing users, the power distribution line is the final link in the transmission of electricity, and its operating status is directly related to the reliability of power supply, power quality and user satisfaction.

[0003] However, in daily life, factors such as strong winds can cause power transmission lines to break. It is common to see power transmission lines broken with one end dangling on the ground. In such cases, it is necessary to carry out maintenance work on the power transmission lines in a timely manner to restore them to their working position and to a working state.

[0004] Currently, the usual approach to maintaining broken power transmission lines is to first temporarily connect the broken wires to provide temporary power, and then replace the entire wire during off-peak hours.

[0005] In existing technologies, when temporarily connecting disconnected power lines, workers need to climb to high places, and it is difficult to manually tension the power lines at high altitudes, making the operation quite dangerous. Summary of the Invention

[0006] The purpose of this invention is to provide a power distribution line maintenance device that can disconnect the connection of power lines without the need for manual climbing, thus restoring the power lines to a high-altitude working state.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is a power distribution line maintenance device, including a workbench and a docking assembly, wherein the docking assembly is disposed on the workbench and is used to dock two sections of wire. The docking assembly includes a support platform, a longitudinal support arm, and a movable support arm. The support platform is located above the workbench and can move vertically. The support platform is provided with a long strip-shaped abutment. The longitudinal support arm is mounted on the support platform and has a pressing device installed at its upper end. The pressing device is used to install the insulating terminal and apply pressure to the insulating terminal. The movable support arm passes through the long strip-shaped abutment on the support platform and has a clamping assembly at its end. The clamping assembly clamps the end of the wire. As the support platform moves upward, the pressing assembly moves upward and the movable support arm flips, allowing the end of the wire to be inserted into the insulating terminal.

[0008] Furthermore, the movable support arm is equipped with a guide bar, which is located inside the elongated abutment interface. The outer end of the elongated abutment interface is coupled with the guide bar, so that when the support platform moves upward, it can apply a thrust to the guide bar.

[0009] Furthermore, the guide bar includes a bottom strip and a top strip, both of which are mated to the movable support arm and both have beveled edges; as the support platform moves upward, the outer end of the long strip-shaped abutment interface abuts against the beveled edge, allowing the movable support arm to flip to a vertical position.

[0010] Furthermore, the guide bar also includes a straight bar, which is located above the top bar and its lower end is connected to the top bar; when the straight bar is located within the long strip-shaped abutment, the movable support arm is in a vertical state.

[0011] Furthermore, the support platform includes an upper platform, a lower platform, and a return support spring. The upper platform is connected to the lower end of the longitudinal support arm; the lower platform is located below the upper platform; the return support spring is located between the upper and lower platforms, and the return spring has a restoring force after compression; a long strip-shaped abutment is provided on the upper and lower platforms; the movable support arm simultaneously passes through the upper and lower platforms.

[0012] Furthermore, the movable support arm is equipped with a blocking component that can abut against the upwardly moving upper platform, aligning the insulated terminal with the end of the wire.

[0013] Furthermore, the clamping assembly includes a housing, a frame, and a locking bar. The housing is connected to the upper end of the movable support arm; the frame has an upward-facing opening for supporting the end of the wire; and the locking bar is hinged to the frame to apply pressure to the wire.

[0014] Furthermore, the frame body is slidably connected to the outer shell. When the movable support arm is in a vertical position, the frame body moves toward the pressing device as the lower platform moves upward.

[0015] Furthermore, the frame is connected to a transmission rack, which meshes with a transmission gear set. When the lower support moves vertically, it can drive the transmission rack to move horizontally through the transmission gear set, bringing the frame closer to the pressing device.

[0016] Furthermore, a positioning component is provided on the workbench, which can lock the position of the workbench.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When it is necessary to connect two broken wires, the ends of the two wires are respectively connected to the corresponding clamping components, and the ends of the wires extend a certain length (5-10cm). Then, the insulating terminal is installed on the crimping device. Then, the lifting component works to push the platform upward. Through the cooperation of the platform and the moving support arm, the moving support arm begins to rotate vertically, and finally the moving support arm is in a vertical state. At this time, the insulating terminal and the end of the wire are on the same horizontal plane. Then, as the platform continues to move upward, the end of the wire is inserted into the insulating terminal. At this time, the ends of the two wires are in close contact. Then, the crimping device is controlled to tighten the insulating terminal, realizing the temporary connection of the two wires. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] See Figure 1 As shown, a power distribution line maintenance device is applicable to the maintenance of incoming power lines. It includes a workbench that can move on the ground, and a positioning component is provided on the workbench. After the workbench is moved to the required position, the positioning component can be used to position the workbench. At this time, the workbench has a certain degree of stability and will not move when it is not subjected to a large external force. A docking component is provided on the workbench. The end of the broken wire is connected to the docking component, and then the wire is docked and repaired through the docking component. In this way, the temporary repair of the power distribution line can be completed.

[0022] See Figures 1 to 3 As shown, the workbench in this invention includes a frame 2 and a tabletop 1. A traveling mechanism is mounted on the frame 2. The workbench can be moved by the operation of the traveling mechanism. The traveling mechanism includes traveling wheels, which are connected to a drive mechanism. The drive mechanism is set on the frame 2. The traveling wheels are rotated by the drive mechanism, thereby moving the workbench. The positioning component is installed on the frame 2, specifically including a positioning seat. The positioning seat is connected to the frame 2 by bolts (a screw hole is provided at a designated position on the frame 2). The positioning seat is connected to the positioning arm 4 through a connecting component. The connection component allows the positioning arm 4 to be flipped on the vertical surface. Initially, the free end of the positioning arm 4 faces upward, which does not affect the movement of the worktable. When positioning is required, the positioning arm 4 can be flipped so that the free end of the positioning arm 4 faces downward, and finally the free end of the positioning arm 4 touches the ground. At this time, the positioning arm 4 can be locked to achieve the positioning operation.

[0023] The positioning seat includes a vertically extending seat plate 3, which is long and narrow. Circular holes are provided at the four corners of the seat plate 3 for bolts to pass through. An upper lifting arm 5 and a lower support arm 6 are provided on the seat plate 3. The upper lifting arm 5 and the lower support arm 6 are parallel to each other and are located near the upper and lower ends of the seat plate 3, respectively. The lower support arm 6 is provided with a lower opening, and a connecting component is provided in the lower opening. The connecting component is connected to the positioning arm 4. During the process of flipping the positioning arm 4, the positioning arm 4 can pass through the lower opening. In this embodiment, the connecting assembly includes an elliptical connecting plate 7, which is connected to the lower support arm 6 via a central axis, allowing the connecting plate 7 to rotate around the central axis. A horizontally extending clamping groove is provided on the lower support arm 6, which communicates with the lower opening. A clamping block is provided in the clamping groove, and the clamping block is connected to a compression return spring. The compression return spring is always in a compressed state, and it uses its own restoring force to move the clamping block outward, so that the clamping block is always in contact with the connecting plate 7. The surface of the clamping block in contact with the connecting plate 7 is an arc surface. When the positioning arm 4 is in a vertical state, the arc surface on the clamping block can be in close contact with the connecting plate 7. At this time, if the positioning arm 4 is not affected by external force, it will not be able to flip.

[0024] In this embodiment, an upper opening is provided on the upper boom 5, and a sliding groove is provided in the upper opening. The sliding groove extends along the length direction of the upper opening. A locking component is provided in the upper opening. Through the operation of the locking component, a downward force can be applied to the positioning arm 4, so that the free end of the positioning arm 4 is tightly pressed against the ground.

[0025] In this embodiment, the aforementioned locking assembly includes a reference base 8. A slide bar is provided at the edge of the reference base 8, and the slide bar fits in a slide groove, allowing the reference base 8 to move horizontally within the upper opening. A threaded hole is provided on the reference base 8, and the threaded hole vertically penetrates the reference base 8. The reference base 8 is connected to a locking arm 9 through the threaded hole. At this time, the locking arm 9 is in a vertical state. When the locking arm 9 rotates, it can move axially. After the locking arm 9 moves downward, the lower end of the locking arm 9 can abut against the positioning arm 4, applying a downward force to the positioning arm 4, so that the free end of the positioning arm 4 only abuts against the ground.

[0026] When the positioning arm 4 is in a vertical position, the upper part of the positioning arm 4 is located inside the upper opening. At this time, the reference seat 8 is located inside the upper opening. The positioning arm 4 blocks the trajectory of the reference seat 8 moving outward, so the reference seat 8 cannot be slid outward directly. When the positioning arm 4 is flipped to face down, its free end is located below the connecting plate 7. At this time, the reference seat 8 can be slid outward, and then the locking arm 9 can be screwed.

[0027] After positioning the workbench, connect the ends of the two wires to the docking assembly. Then, by working the docking assembly, bring the ends of the two wires closer together to form a dock.

[0028] See Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the docking assembly includes a longitudinal support arm 10 and a movable support arm 11. The lower end of the movable support arm 11 is hinged to a reference support arm 12, which is fixed on the workbench. A support platform is provided below the longitudinal support arm 10. The support platform is connected to the workbench through a lifting assembly 13. The lower end of the longitudinal support arm 10 is fixed on the support platform. The lifting assembly 13 adopts an electric push rod or a hydraulic push rod. Its output end faces upward and when it works, it can make the output end move vertically, thereby driving the support platform and the longitudinal support arm 10 to move, so that the ends of the two wires move upward. See Figures 5 to 9 As shown, a crimping device 14 is fixed at the upper end of the longitudinal support arm 10. Through the operation of the lifting assembly 13, the crimping device 14 can be moved to a high position. During the upward movement of the longitudinal support arm 10, the movable support arm 11 can be operated to move the end of the wire upward and finally insert the end of the wire into the crimping device 14. Then, the two wires are connected by the operation of the crimping device 14. It should be noted that the working end of this crimping device 14 is equipped with an insulating terminal. When the movable arm moves to the corresponding position, the ends of the two wires are located in the insulating terminal. Moreover, the crimping device 14 in this embodiment is an existing integrated insulating crimper, which is connected to a remote control switch through a wire to control its working state.

[0029] To enable the movable support arm 11 to operate, two elongated abutment interfaces 15 are provided on the aforementioned support platform. These two elongated abutment interfaces 15 are symmetrically arranged with the longitudinal support arm 10 as the central axis. When the movable support arm 11 passes through the corresponding elongated abutment interface 15, initially, the movable support arm 11 is slightly tilted. A clamping component is connected to the free end of the movable support arm 11, which can clamp the wire. After the lifting component 13 operates, the support platform applies a force to the movable support arm 11, causing the movable support arm 11 to flip upward. During this process, the clamping component moves in an arc trajectory, moving from a low position to a high position. When the movable support arm 11 is in a vertical state and coupled with the longitudinal support arm 10, the clamping component is aligned with the output port of the crimping device 14, at which point the end of the wire enters the output port of the crimping device 14.

[0030] The movable support arm 11 can only move upward after being subjected to an upward force by the support platform. In order to enable the movable support arm 11 to move smoothly, a guide bar 16 is provided on the movable support arm 11. The guide bar 16 extends along the length of the movable support arm 11. When the movable support arm 11 is in a horizontal state, there is a certain vertical distance between the movable support arm 11 and the support platform. At this time, the movable support arm 11 contacts the outer end of the long strip-shaped abutment interface 15 on the support platform through the bottom part of the guide bar 16. See Figure 4As shown, the guide bar 16 includes a bottom bar 17, a middle bar 18, and a top bar 19. Both the bottom bar 17 and the top bar 19 are provided with beveled edges. When the movable support arm 11 is in a horizontal state, the beveled edge of the bottom bar 17 contacts the outer end of the elongated abutment interface 15. When the support platform moves upward, the support platform applies a force to the bottom bar 17 and is affected by the beveled edge of the bottom bar 17. During the upward movement of the support platform, the movable support arm 11 can be smoothly rotated and moved. During the rotation of the movable support arm 11, the outer end of the elongated abutment interface 15 exits from the bottom bar... After the plate 17 passes, it will contact the middle strip plate 18. As the support platform gradually rises, the support platform will also contact the inclined edge of the top strip plate 19. During this process, the movable support arm 11 will gradually move to a vertical state, allowing the wire end to enter the output port of the crimping device 14. When the movable support arm 11 is in a vertical state, the movable support arm 11 abuts against the inner end of the long strip abutment interface 15. At this time, the inclined edge of the top strip plate 19 abuts against the outer end of the long strip abutment interface 15, making the movable support arm 11 stable. When the support platform does not move vertically, the movable support arm 11 will not move. In order to enable the movable support arm 11 to be reset, a push-back component is provided on the upper surface of the support platform. After the wire ends are connected, the crimping device 14 is separated from the insulating terminal. At this time, the lifting component 13 can be controlled to work, driving the support platform to move downward. During the downward movement of the support platform, the outer end of the long strip-shaped abutment 15 gradually separates from the inclined edge of the top strip 19. Thus, under the action of the push-back component, the movable support arm 11 is flipped outward. Finally, as the support platform moves downward, the movable support arm 11 gradually returns to the horizontal state.

[0031] See Figure 9 As shown, the push-back assembly includes a flat sleeve 20, which is mounted on the support platform. A push-back rod 21 passes through the flat sleeve 20 and is connected to the flat sleeve 20 via a tension spring. When the movable support arm 11 is in a vertical position, the movable support arm 11 abuts against the end of the push-back rod 21. At this time, the tension spring is in a stretched state and has a restoring force. However, since the outer end of the long strip-shaped abutment interface 15 abuts against the inclined edge of the upper plate, the movable support arm 11 cannot move at this time. When the support platform moves downward, the support platform no longer contacts the inclined edge of the upper plate. At this time, under the action of the restoring force of the tension spring, the push-back rod 21 is reset, and a restoring thrust is applied to the movable support arm 11.

[0032] See Figure 6As shown, in this embodiment, a clamping assembly is provided at the upper end of the movable support arm 11. The clamping assembly includes a housing 22 with a U-shaped cross-section. A U-shaped frame 23 is provided inside the housing 22 with the opening facing upward. Two locking holes 24 are provided on the frame 23, which are close to the corresponding ends of the frame 23. A locking strip 25 passes through each locking hole 24. The locking strip 25 can be flipped, with one end located inside the opening of the frame 23 and the other end located outside the frame 23. When the outer end of the locking strip 25 is pushed upward, it can flip. A pressure cover 26 is hinged to the inner end of the locking strip 25. The pressure cover 26 is located inside the frame 23. The wire is locked by the cooperation between the pressure cover 26 and the frame 23. See Figure 5 and Figure 7 As shown, a longitudinal flat slot 27 and a longitudinal strip slot 28 are provided on the movable support arm 11. The longitudinal flat slot 27 and the longitudinal strip slot 28 are connected. An electric lock push device 29 is provided in the longitudinal flat slot 27. The electric lock push device 29 is connected to a remote controller, which can control the operation of the electric lock push device at a higher position from the ground position.

[0033] In this embodiment, the electric lock push device 29 adopts an existing electric linear actuator. The output end of the electric lock push device 29 is connected to a flat support rod 30. Both ends of the flat support rod 30 pass through the longitudinal strip opening 28 on the corresponding side. A longitudinal top rod 31 is fixed at the end of the flat support rod 30. The longitudinal top rod 31 is parallel to the movable support arm 11 and extends upward. A horizontal tight push rod 32 is fixed at the upper end of the longitudinal top rod 31. When the electric lock push device 29 works, it can drive the flat support rod 30 to move, so that the horizontal tight push rod 32 moves closer to or away from the locking bar 25. At this time, the two horizontal tight push rods 32, the two longitudinal top rods 31 and the flat support rod 30 form a lock push arm. When the lock push arm applies a pushing force to the outer end of the locking bar 25, it can make the inner end of the locking bar 25 move downward, thereby clamping the wire located in the frame 23. To ensure that the end of the wire remains horizontal after being clamped, a bottom plate is provided on the frame 23. When the wire is clamped and locked, the end of the wire is in contact with the bottom plate. When the movable support arm 11 is in a vertical state, the bottom plate is in a horizontal state. To allow the end of the wire to smoothly enter the insulating terminal, the frame 23 and the outer shell 22 are slidably connected. For example, a groove is provided on the inner side of the outer shell 22. When the opening of the outer shell 22 faces upward, the groove extends horizontally. A slide bar is fixed on the frame 23. The slide bar is located in the groove, and a roller is provided on the slide bar. The roller is also located in the groove, thereby facilitating the horizontal movement of the frame 23. To enable the frame 23 to move along the length of the slide, a transmission rack 33 is fixed on the frame 23, and a transmission gear 34 is provided below the transmission rack 33. The transmission gear 34 meshes with the transmission rack 33 and is connected to the outer shell 22 via a shaft. A through-hole is provided on the outer shell 22, through which a transmission chain 35 passes, and the transmission chain 35 is connected to the transmission gear 34. A lower gear 36 is provided on the movable support arm 11, and the lower gear 36 is connected to the transmission gear 34 via the transmission chain 35. When the lower gear 36 rotates, it causes the transmission gear 34 to rotate. The lower gear 36 is connected to an outer gear 37 via a shaft. 7 and the lower gear 36 are located on different vertical planes. The outer gear 37 can rotate synchronously with the lower gear. The outer gear 37 meshes with the drive gear 38. The drive gear 38 is connected to the movable support arm 11 through the horizontal support rod 39. The drive gear 38, the outer gear 37 and the lower gear 36 form a transmission gear 34 group. During the upward movement of the support platform, it can cooperate with the drive gear 38. When the movable support arm 11 is in a vertical state, the upward movement of the support platform can make the drive gear 38 rotate, and then the transmission gear group can make the frame 23 translate. The frame 23 moves towards the insulating terminal on the crimping device 14, so that the wire end can be inserted into the insulating terminal.

[0034] See Figure 8 As shown, the support platform in this embodiment includes an upper platform 40 and a lower platform 41. The lower platform 41 is connected to the output end of the lifting assembly 13. Both the upper platform 40 and the lower platform 41 are provided with a long strip-shaped abutment interface 15. A return support spring 42 is connected between the upper platform 40 and the lower platform 41. The return support spring 42 will generate a restoring force after compression. A blocking component 43 is provided on the movable support arm 11. The blocking component 43 is close to the upper end of the movable support arm 11. When the movable support arm 11 is in a vertical state, as the lifting assembly 13 works, it pushes the upper platform 40 and the lower platform 41 upward. When the upper platform 40 contacts the blocking component 43, the upper platform 40 cannot continue to move, while the lower platform 41 can continue to move upward. A flat short tube 44 passes through the upper platform 40, and a longitudinal rack 45 passes through the flat short tube 44. The lower end of the longitudinal rack 45 is fixed to the lower platform 41. As the lower platform 41 continues to move upward, the longitudinal rack 45 can move. After the longitudinal rack meshes with the drive gear 38, the drive gear 38 can rotate as the longitudinal rack 45 continues to move, thereby realizing the translation of the frame 23.

[0035] In this embodiment, the guide bar 16 also includes a straight bar 46. The lower end of the straight bar 46 is connected to the top bar 19. After the upper plate 40 passes the top bar 19, the movable support arm 11 is already in a vertical state. Then, as the upper plate 40 continues to move upward, the straight bar 46 enters the elongated abutment interface 15 on the upper plate 40. At this time, the movable support arm 11 cannot be reset and flipped, thereby ensuring that the movable support arm 11 can be in a vertical state.

[0036] In addition, when the upper plate 40 abuts against the blocking member 43, the wire end is flush with the insulating terminal on the crimping assembly, so that the wire end can be inserted into the insulating terminal after the frame 23 is translated. Therefore, the straight distance between the bottom of the frame 23 and the blocking member 43 is equal to the straight distance from the insulating terminal to the upper plate 40.

[0037] Finally, the aforementioned movable support arm 11 has a telescopic structure, and the length of the movable support arm 11 can be adjusted before the lifting device is in operation. When the length of the movable support arm 11 changes, the length of the intermediate strip 18 in the guide strip 16 also changes accordingly. That is, the intermediate strip 18 also has a telescopic structure, so as to meet the construction of wire connection at different heights. Since the telescopic structure is existing technology, its distance composition structure will not be described in detail.

[0038] When applying this technical solution, the insulation layer at the end of the wire needs to be stripped first, and then the ends of the two wires are connected. It is applicable to the scenario of a long wire being disconnected, that is, the disconnected ends of the two wires can be connected to the clamping component at the end of the horizontal movable support arm 11. When the wire is not long enough and the break point is close to the end of the wire, only one movable support arm 11 can be used, but in this case, operators need to climb up to assist in the operation.

[0039] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
