Abstract

This invention discloses a non-powered UAV tow rope mounting tool and method. Openings for accommodating overhead lines are provided at the lower part of two overhead line supports, which are connected by pivots A and B. A fixed pulley is mounted on pivot A. A guide assembly is connected to pivot A. A counterweight can be engaged with a counterweight storage tube, which is connected to a ring-lock structure. The ring-lock structure is connected to pivot B, and the counterweight storage tube is connected to a connecting rope. The other end of the connecting rope passes through a lifting assembly and connects to the guide assembly.

The opening is opened and closed through the guide assembly and the ring-lock structure. The counterweight can be locked by the counterweight storage tube, and the counterweight is connected to the tow rope. The other end of the tow rope extends freely after passing through the fixed pulley. This allows the mounting tool to be mounted on an overhead line.

Description

Technical Field

[0001] This invention relates to the field of mounting tools, and in particular to a non-powered drone tow rope mounting tool and mounting method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Hanging traction ropes on overhead lines to enable personnel to access the lines, attach grounding wires, or raise other overhead devices for line work is an important operational method. However, the main existing technical method is to hang the traction rope directly on the overhead line, which causes the traction rope to come into direct contact with the overhead line and rub against it, resulting in a certain degree of damage to both the traction rope and the overhead line. There are also methods that use a mounting tool to attach the traction rope to the overhead line, but the fixed pulley of the mounting tool is below the overhead line, and the lower end of the tool is far away from the overhead line, which only meets the single operation requirement of attaching the grounding wire. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a non-powered drone traction rope mounting tool and method. This tool can be mounted on an overhead power line, and the traction rope can pull an insulated rope into the tool, allowing workers or other equipment to climb onto the overhead power line via the insulated rope. Furthermore, fixed pulleys, limit pulleys, and guide components isolate the traction rope from the overhead power line, preventing damage to the traction rope.

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

[0006] Firstly, a non-powered UAV tow rope mounting tool is proposed, including a fixing component, a guiding component, a lifting component, and a counterweight storage component; the lifting component is connected to the fixing component and can move up and down relative to the fixing component; the fixing component includes two overhead line supports located on both sides, the lower part of the two overhead line supports is provided with an opening to accommodate the overhead line, the two overhead line supports are connected by a rotating shaft A and a rotating shaft B, and a fixed pulley is provided on the rotating shaft A; the guiding component is connected to the rotating shaft A;

[0007] The counterweight storage assembly includes a ring-lock structure, a counterweight storage tube, and a counterweight. The counterweight can be engaged with the counterweight storage tube, which is connected to the ring-lock structure. The ring-lock structure is connected to the rotating shaft B, and the counterweight storage tube is connected to a connecting rope. The other end of the connecting rope passes through the lifting assembly and connects to the guide assembly. When the lifting assembly moves up and down relative to the fixed assembly, it can drive the connecting rope to move up and down, thereby causing the ring-lock structure to rotate relative to the rotating shaft B and the guide assembly to rotate relative to the rotating shaft A. The opening is opened and closed through the guide assembly and the ring-lock structure. The counterweight is connected to a traction rope, the other end of which extends freely after passing through a fixed pulley.

[0008] Secondly, a method for mounting a tow rope attachment tool for a non-powered unmanned aerial vehicle (UAV) as proposed in the first aspect is presented, including:

[0009] Connect the weight to the weight storage pipe;

[0010] When the lifting assembly is attached to the drone, it moves upward relative to the fixed assembly, causing the connecting rope to move upward, which in turn causes the weight storage tube to rotate clockwise relative to the rotating shaft B, and the guide assembly to rotate counterclockwise relative to the rotating shaft A, opening the opening to accommodate the overhead line.

[0011] The mounting tool is transported to the suspension point by drone, so that the overhead line is located in the opening that accommodates the overhead line;

[0012] When the drone is detached from the lifting assembly, the lifting assembly moves downward relative to the fixed assembly, causing the connecting rope to move downward, which in turn causes the counterweight storage tube to rotate counterclockwise relative to the rotating shaft B, and the guide assembly to rotate clockwise relative to the rotating shaft A, thus closing the opening that accommodates the overhead line.

[0013] Release the weight from the weight storage tube to the ground.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention enables the mounting tool to be mounted on an overhead line, and by connecting the traction rope and the insulating rope, the traction rope can pull the insulating rope into the mounting tool, allowing workers or other online devices to climb onto the overhead line via the insulating rope, thus enabling workers or other online devices to perform online operations. In addition, the traction rope is isolated from the overhead line by a fixed pulley, preventing damage to the traction rope.

[0016] 2. The ring-lock structure of the present invention is connected to the rotating shaft B and can rotate relative to the rotating shaft B. When the ring-lock structure rotates, it can cooperate with the guide component to open and close the opening for accommodating the overhead line, enabling the mounting tool to be suspended on the overhead line and the overhead line to be locked to prevent the tool from falling off the overhead line.

[0017] 3. The present invention provides a limit lock A and a limit lock B on the lifting assembly. When the opening is closed by the ring lock structure and the guide assembly, the limit lock A and the limit lock B can prevent the locking structure and the guide assembly from rotating, thereby opening the opening and preventing the mounting tool from falling off the overhead line.

[0018] 4. The present invention also provides a limiting pulley and a limiting connecting shaft. The traction rope passes between the limiting pulley and the fixed pulley, and between the fixed pulley and the limiting connecting shaft. The limiting pulley and the limiting connecting shaft limit the traction rope, prevent the traction rope from slipping off the fixed pulley, and ensure that the traction rope can slide smoothly along the fixed pulley.

[0019] 5. The present invention also provides a limiting connector and a limiting boss on the fixed component. The limiting connector limits the clockwise rotation angle of the weight storage component, and the limiting boss limits the counterclockwise rotation angle of the guide component, thereby ensuring the stability of the performance of the mounting tool.

[0020] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] Example 1

[0035] In this embodiment, a non-powered drone tow rope mounting tool is disclosed, such as... Figures 1-8 As shown, the mounting tool 30 includes a fixing component 1, a guiding component 2, a lifting component 4, and a counterweight storage component 3; the lifting component 4 is connected to the fixing component 1 and can move up and down relative to the fixing component 1; the fixing component 1 includes two overhead line supports located on both sides, the lower part of the two overhead line supports is provided with an opening to accommodate the overhead line, the two overhead line supports are connected by a rotating shaft A5 and a rotating shaft B6, and a fixed pulley 9 is provided on the rotating shaft A5; the guiding component 2 is connected to the rotating shaft A5;

[0036] The weight storage assembly 3 includes a ring-lock structure 12, a weight storage tube 24, and a weight 27. The weight 24 can be engaged with the weight storage tube 24. The weight storage tube 24 is connected to the ring-lock structure 12, which is connected to the rotating shaft B6. The weight storage tube 24 is connected to the connecting rope 7. The other end of the connecting rope 7 passes through the lifting assembly 4 and is connected to the guide assembly 2. When the lifting assembly 4 moves up and down relative to the fixed assembly 1, it can drive the connecting rope 7 to move up and down, thereby driving the ring-lock structure 12 to rotate relative to the rotating shaft B6 and the guide assembly 2 to rotate relative to the rotating shaft A5. The opening for accommodating the overhead line is opened and closed through the guide assembly 2 and the ring-lock structure 12. The weight 27 is connected to the traction rope 26. The other end of the traction rope 26 extends out after passing through the fixed pulley 9. This extended end can be used to connect to the insulating rope.

[0037] Specifically, the weight storage pipe 24 and the guide component 2 are located on both sides of the opening that accommodates the overhead line, so that the ring lock structure 12 and the guide component 2 are located on both sides of the opening that accommodates the overhead line.

[0038] When the ring-lock structure 12 rotates counterclockwise relative to the rotating shaft B6 and the guide assembly 2 rotates clockwise relative to the rotating shaft A5, the guide assembly 2 and the ring-lock structure 12 can close the opening that accommodates the overhead line.

[0039] When the ring-lock structure 12 rotates clockwise relative to the rotating shaft B6 and the guide assembly 2 rotates counterclockwise relative to the rotating shaft A5, the guide assembly 2 and the ring-lock structure 12 can open the opening to accommodate the overhead line.

[0040] The lifting assembly 4 can be suspended onto the drone. When the lifting assembly 4 is suspended onto the drone, it moves upward relative to the fixed assembly 1, that is, the lifting assembly 4 is in an extended state relative to the fixed assembly 1. At this time, the ring-locking structure 12 rotates clockwise relative to the rotating shaft B6, and the guide assembly 2 rotates counterclockwise relative to the rotating shaft A5. The guide assembly 2 and the ring-locking structure 12 open the opening to accommodate the overhead line. Figure 3 As shown; in this state, the mounting tool 30 is placed on the overhead line 8. When the mounting tool 30 is placed on the overhead line 8, the lifting assembly 4 is detached from the drone, and the lifting assembly 4 moves downward relative to the fixed assembly 1, resetting to its original position. Figure 1 , Figure 2 In the state shown, the ring-locking structure 12 rotates counterclockwise relative to the rotating shaft B6, and the guide component 2 rotates clockwise relative to the rotating shaft A5. The guide component 2 and the ring-locking structure 12 close the opening accommodating the overhead line. This achieves ring locking of the overhead line and prevents the mounting tool 30 from slipping off the overhead line 8.

[0041] Fixed components such as Figure 4 , Figure 5As shown, it includes two overhead line supports located on both sides. The lifting assembly 4 is connected to the overhead line supports and can move up and down relative to the overhead line supports. The lower part of the two overhead line supports is provided with an opening to accommodate the overhead line. The two overhead line supports are connected by a rotating shaft A5 and a rotating shaft B6. A fixed pulley 9 is provided on the rotating shaft A5. The fixed pulley 9 can rotate relative to the rotating shaft A5. The traction rope 26 and the insulating rope can both pass through the surface of the fixed pulley 9. The fixed pulley 9 is used to bear the tension of the traction rope 26 and the insulating rope, and to prevent the traction rope 26 and the insulating rope from directly contacting the overhead line 8.

[0042] The overhead line support includes an overhead line receiving structure, a first guide structure 19, and a second guide structure 20. The lower part of the overhead line receiving structure is provided with an opening to receive the overhead line. The first guide structure 19 and the second guide structure 20 are located on both sides of the opening and are connected to the overhead line receiving structure. The two overhead line receiving structures are connected by a rotating shaft A5 and a rotating shaft B6.

[0043] The lifting assembly 4 is connected to the first guide structure 19 and can move up and down relative to the first guide structure 19. The second guide structure 20 and the first guide structure 19 form a trumpet-shaped opening, and the larger end of the trumpet-shaped opening is located at the bottom. The trumpet-shaped opening can provide guidance for the overhead line 8, making it easier for the overhead line 8 to enter the opening that accommodates the overhead line.

[0044] Rubber blocks are installed in the overhead line receiving structure, and the lower part of the rubber blocks has an opening to accommodate the overhead line. Specifically, the rubber blocks in the two overhead line receiving structures are rubber block A and rubber block B. Both rubber block A and rubber block B are in contact with the overhead line, which can avoid the problem of axial movement of the mounting tool on the overhead line due to the slope of the overhead line.

[0045] A limiting connecting shaft 13 is connected between the two overhead line supports. A limiting pulley 17 is installed on the rotating shaft B6. The traction rope passes between the limiting connecting shaft 13 and the fixed pulley 9, and between the limiting pulley 17 and the fixed pulley 9. The limiting connecting shaft 13 and the limiting pulley 17 guide and position the traction rope and the insulating rope to prevent the traction rope and the insulating rope from falling off the fixed pulley 9.

[0046] In addition, the fixing component 1 is also provided with a limiting connector 18 and a limiting boss 16. The limiting connector 18 is used to limit the clockwise rotation angle of the weight storage component to prevent the clockwise rotation angle of the weight storage component from being too large. The limiting boss 16 is used to limit the counterclockwise rotation angle of the guide component 2 to prevent the counterclockwise rotation angle of the guide component 2 from being too large.

[0047] like Figure 6 , Figure 7 As shown, the weight storage assembly 3 includes a ring lock structure 12, a weight storage tube 24, and a weight 27, with the upper part of the weight 27 connected to the traction rope 26.

[0048] The ring-lock structure 12 is used to prevent the mounting tool 30 from falling off the overhead line when the opening accommodating the overhead line is closed.

[0049] The end of the ring-lock structure 12 is provided with a rotating hole 21, through which the ring-lock structure 12 is connected to the rotating shaft B6, and the ring-lock structure 12 can rotate relative to the rotating shaft B6.

[0050] A closing limiting boss 22 is provided on the ring lock structure 12. When the ring lock structure 12 and the guide component 2 close the opening for accommodating the overhead line, the closing limiting boss 22 contacts the fixing component 2, limiting the counterclockwise rotation angle of the ring lock structure 12 and preventing the ring lock structure 12 from rotating too much counterclockwise.

[0051] The ring lock structure 12 is also equipped with a guide bearing 23, which is used to guide and position the traction rope 26 to prevent the traction rope 26 from directly contacting the overhead line 8.

[0052] A steel cable fixing structure 25 is also provided on the ring-lock structure 12, and one end of the connecting rope 7 is connected to the steel cable fixing structure 25.

[0053] The weight storage tube 24 is connected to the ring lock structure 12. The weight 27 can be engaged with the weight storage tube 24, and can also detach from the bottom of the weight storage tube 24 under its own gravity.

[0054] One end of the traction rope 26 is connected to the counterweight 27, and the other end of the traction rope 26 passes through the upper end of the counterweight storage tube 24, passes through the guide bearing 23, the space between the limit pulley 17 and the fixed pulley 9, and the space between the limit connecting shaft 13 and the fixed pulley 9, and passes through the upper surface of the fixed pulley 9, thereby isolating the traction rope from the overhead line and providing guidance for the traction rope.

[0055] In practice, the weight can be unlocked or locked in the weight storage tube by repeatedly pulling the traction rope. If the weight is unlocked, it can detach from the weight storage tube and descend under gravity, thereby pulling the traction rope. When the weight is locked, it is locked in the weight storage tube and in fixed contact with the tool. In the locked state, the weight can be unlocked by pulling the traction rope. In the unlocked state, the weight is pulled into the weight storage tube by pulling the traction rope to lock it in place. Unlocking and locking can be achieved simply by the ground operator pulling the traction rope or insulated rope.

[0056] In addition, the hammer can also be connected to the grounding wire.

[0057] The lifting assembly 4 has a channel for the connecting rope 7 to pass through, and a pulley is installed in the channel. One end of the connecting rope 7 is connected to the ring-lock structure 12, and the other end passes through the channel and is connected to the guide assembly 2. The connecting rope contacts the pulley in the channel. When the lifting assembly 4 moves up and down relative to the fixed assembly 1, it causes the connecting rope 7 to move up and down relative to the fixed assembly, which in turn causes the ring-lock structure 12 to rotate relative to the rotating shaft B6, thereby causing the guide assembly 2 to rotate relative to the rotating shaft A5.

[0058] Preferably, the connecting rope is made of steel cable.

[0059] In addition, the lifting assembly 4 is equipped with limit locks A10 and B11. When the opening is closed by the ring lock structure and the guide assembly, limit lock A10 can contact the ring lock structure to prevent the ring lock structure from rotating instantaneously; limit lock B can contact the guide assembly to prevent the guide assembly from rotating counterclockwise, thereby preventing the opening for accommodating the overhead line from opening.

[0060] The method for transporting workers or work equipment to an overhead platform using the mounting tool disclosed in this embodiment includes:

[0061] (1) Hang the lifting assembly of the mounting tool with the traction rope onto the UAV. The hammer is locked in the hammer storage tube and the lifting assembly is in the extended state. The hammer storage assembly and the guide assembly are in the rotating open state.

[0062] (2) The UAV carrying the mounting tool arrives near the tool mounting point of the overhead line, places the mounting tool on the mounting point, and detaches the UAV from the lifting assembly. Under the action of gravity, the mounting tool moves downward relative to the fixed assembly, causing the lifting assembly to reset. The counterweight storage assembly rotates counterclockwise, and the guide assembly rotates clockwise to close the opening that accommodates the overhead line. The lifting assembly locks the counterweight storage assembly and the guide assembly in place. The mounting tool is locked on the line.

[0063] (3) The operator pulls the traction rope on the ground. The traction rope drives the hammer to rise a certain distance, triggering the mechanism inside the hammer storage tube, thus unlocking the hammer. The hammer falls under the action of gravity, driving the traction rope to rise.

[0064] (4) The traction rope on the side of the counterweight descends to the ground. The operator pulls the traction rope on the side of the counterweight. The end of the traction rope on the other side is fixed to the insulating rope. The insulating rope rises to the mounting tool under the pulling action of the operator and passes through the mounting tool to reach the ground. The operator then fixes the insulating rope to the ground. The fixing operation of the insulating rope is now complete.

[0065] (5) Workers or equipment use climbing devices to ascend the overhead line via insulated ropes to carry out operations;

[0066] (6) After the workers have completed the work, pull the insulating rope to lower it to the ground;

[0067] (7) The operator unties the insulating rope fixed to the ground and pulls the insulating rope on the side without the counterweight until the counterweight rises into the counterweight storage tube in the mounting tool, triggering the locking mechanism in the storage tube to lock and fix the counterweight in the storage tube.

[0068] (8) The operator uses a drone to remove the mounting tool from the line. When the drone lifts the mounting tool, the lifting component moves upward relative to the fixed component, causing the weight storage component to rotate clockwise and the guide component to rotate counterclockwise, opening the opening to accommodate the overhead line, unlocking the mounting tool on the line, and the drone carries the mounting tool back to the ground, thus completing the entire operation.

[0069] The method for attaching a grounding wire using the tools disclosed in this embodiment includes:

[0070] (1) Hang the tool with the traction rope on the drone. The hammer is in the locked state, the lifting component is in the extended state, and the hammer storage component and guide component are in the rotating open state.

[0071] (2) The UAV carrying the tool arrives near the tool mounting point on the line, places the tool on the mounting point, the UAV detaches from the tool, the tool is lifted by gravity and the lifting component descends and resets, the weight storage component and the guide component rotate and reset, the lifting component locks the weight storage component and the guide component; the tool ring is locked on the line.

[0072] (3) The operator pulls the traction rope on the ground. The traction rope drives the hammer to rise a certain distance, triggering the mechanism inside the hammer storage tube, thus unlocking the hammer. The hammer falls under the action of gravity, driving the traction rope to rise.

[0073] (4) After the hammer falls to the ground, the operator connects the grounded wire to the hammer.

[0074] (5) The operator pulls the traction rope on the side without the weight until the weight rises into the weight storage tube inside the tool, triggering the locking mechanism inside the storage tube to lock and fix the weight inside the storage tube, thus connecting the grounding wire to the tool; the grounding operation is thus completed.

[0075] (6) After the entire operation is completed, the operator pulls the traction rope on the side without the weight to unlock the weight, and the weight descends to the ground under the action of gravity.

[0076] (7) The operator removes the grounding wire from the counterweight;

[0077] (8) The operator pulls the insulating rope on the side without the counterweight until the counterweight rises into the counterweight storage tube inside the tool, triggering the locking mechanism inside the storage tube to lock and fix the counterweight inside the storage tube.

[0078] (9) The operator uses a drone to remove the tools from the line. When the drone lifts the tools, the lifting component extends, causing the weight storage component and guide component to rotate and open. The tools are unlocked on the line, and the drone carries the tools back to the ground, thus completing the entire operation.

[0079] Example 2

[0080] In this embodiment, a method for mounting a tow rope attachment tool for a non-powered unmanned aerial vehicle (UAV) as disclosed in Embodiment 1 is presented, comprising:

[0081] Connect the weight to the weight storage pipe;

[0082] When the lifting assembly is attached to the drone, it moves upward relative to the fixed assembly, causing the connecting rope to move upward, which in turn causes the weight storage tube to rotate clockwise relative to the rotating shaft B, and the guide assembly to rotate counterclockwise relative to the rotating shaft A, opening the opening to accommodate the overhead line.

[0083] The mounting tool is transported to the suspension point by drone, so that the overhead line is located in the opening that accommodates the overhead line;

[0084] When the drone is detached from the lifting assembly, the lifting assembly moves downward relative to the fixed assembly, causing the connecting rope to move downward, which in turn causes the counterweight storage tube to rotate counterclockwise relative to the rotating shaft B, and the guide assembly to rotate clockwise relative to the rotating shaft A, thus closing the opening that accommodates the overhead line.

[0085] Release the weight from the weight storage tube to the ground.

[0086] 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 it.
