Description

Technical Field

[0001] This invention relates to the field of power line installation, and in particular to a disassembly and assembly mechanism suitable for assembling and disassembling spacers on unmanned aerial vehicles (UAVs). Background Technology

[0002] Currently, in the disassembly and assembly process of spacers, apart from manual and cableway-type equipment installation, the most convenient method is drone-based assembly and disassembly. In order to facilitate the installation of spacers by drones, the form of patent numbers CN117526208A and CN117526208A is generally adopted, which uses the clamping structure of the left and right parts to achieve the fixing function.

[0003] However, in the current drone installation process, in order to reduce the load on the drone and shorten the stroke required by the clamping structure, it is generally not possible to set up a robotic arm or an overly complex clamping structure. Especially in high-altitude operations, where the width of the structure that needs to clamp the wire is small, the drone needs to be repeatedly aligned with the clamping structure and fitted onto the wire. However, the currently available wider clamping structures cannot be detached from the spacer after the clamping operation is completed, resulting in a large gravitational load on both the wire and the drone. At the same time, the process of removing the spacer from the wire after clamping is also required to reverse the process, and the user needs to use the drone to operate repeatedly. Therefore, how to solve the above technical problems is in line with the current technological development trend. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an assembly and disassembly mechanism for assembling and disassembling spacers for UAVs.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal communication between two components. All technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0044] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] like Figure 1 As shown, the present invention provides a spacer 102 and its assembly / disassembly mechanism suitable for assembling and disassembling a drone 1, including a drone 1, a rope 101, a spacer 102, an assembly / disassembly structure 2, a control terminal 103 and a wire 104. The assembly / disassembly structure 2 is located at both ends of the spacer 102, and the drone 1 and the assembly / disassembly structure 2 are connected by the rope 101. The control terminal 103 is communicatively connected to the assembly / disassembly structure 2.

[0046] The equipment is mainly controlled by the control terminal 103, which operates the assembly and disassembly structure 2 to form a clamping operation on the wire 104.

[0047] In one implementation, such as Figure 2-4 In the middle, the spacer 102 includes spacer end sleeves 105 at both ends. A docking sleeve 3 is installed at one end of the spacer end sleeve 105. A one-way rack 301 is provided on the upper part of the docking sleeve 3. The assembly and disassembly structure 2 includes a push end sleeve 4 and a motor housing 5. The push end sleeve 4 and the motor housing 5 are slidably telescopically connected. The motor housing 5 is used to drive the push end sleeve 4 to telescopically move on its surface. The end of the motor housing 5 is spliced ​​with the docking sleeve 3. A movable clamp 6 and a fixed clamp 7 are sleeved on the surface of the docking sleeve 3. The fixed clamp 7 is fixedly installed on the surface of the docking sleeve 3. The movable clamp 6 is used to slide axially on the surface of the docking sleeve 3 and the motor housing 5. The movable clamp 6 is pushed by the push end sleeve 4. The movable clamp 6 is axially limited by the one-way rack 301. A limiting structure is provided on the upper inner side of the movable clamp 6.

[0048] During the installation process, the main action is to push the movable clamp 6 located on the motor housing 5 continuously, causing the movable clamp 6 to move towards the fixed clamp 7 until the limiting structure inside the movable clamp 6 contacts the one-way toothed groove on the upper surface of the mating sleeve 3. Since the direction of the one-way toothed groove is mainly towards the fixed clamp 7, the limiting structure ensures that the movable clamp 6 can only move towards the fixed clamp 7. This allows the movable clamp 6 to move again after the pushing end sleeve 4 has finished pushing and clamping, thus increasing the distance between the movable clamp 6 and the fixed clamp 7 before suspending the spacer bar 102, and naturally narrowing it after pushing and clamping. This allows both ends of the spacer bar 102 to be quickly suspended and clamped onto the wire 104.

[0049] In one embodiment, the movable clamp 6 is provided with a lifting ring 8 at the top, and the limiting structure is connected to the lifting ring 8. The lifting ring 8 is used to unlock the one-way rack 301 from limiting the movable clamp 6.

[0050] Its structure primarily ensures that after the aforementioned installation process is completed, only the docking sleeve 3 and the movable clamp 6 remain, reducing the overall weight of the spacer 102 and the burden on the wire 104 and subsequent disassembly of the drone 1. During disassembly, the drone 1 only needs to be connected to the rope 101 using a hook, such as a fixed rope 101 or a shorter flexible rope 101, so that the drone 1 only needs to lift the lifting ring 8 to release the movable clamp 6. During the upward lifting process, the wire 104 can move downward along the curved structure between the movable clamp 6 and the fixed clamp 7, causing the movable clamp 6 to be squeezed out to the outside, thereby achieving the effect of overall release. This reduces the process required for disassembly, and the operator only needs to lift the lifting ring 8 upward.

[0051] In one implementation, such as Figure 2 , 5 As shown in Figure -7, the motor housing 5 includes:

[0052] Rotary motor 501 is located near the end of the push end sleeve 4 and is used to drive the push end sleeve 4.

[0053] Drive motor 502 is located near the end of docking sleeve 3. Drive motor 502 is used to fix or unlock the connection with docking sleeve 3.

[0054] Connecting screw 503 is connected to drive motor 502 for transmission.

[0055] Motor mounting bracket 504 is used to fix drive motor 502 and bearing 11 seat that constitutes connecting screw 503;

[0056] The driving end set 4 includes:

[0057] Lead screw 401 is connected to rotary motor 501 for transmission.

[0058] Thread nut 402 is used to thread the lead screw 401, and the lead screw 401 passes through the center of thread nut 402;

[0059] The end of the connecting sleeve 3 near the motor housing 5 is provided with a screw slot 302, and the screw slot 302 is spliced ​​and installed with the connecting screw 503 accordingly.

[0060] The upper surface of the end of the motor housing 5 is provided with a rope 101 fixing buckle, which is connected to the rope 101. The lower surface of the end of the motor housing 5 is provided with a connecting block 506. A controller 9 is installed at the bottom of the connecting block 506. The controller 9 includes a circuit board 901 inside. The circuit board 901 is used to carry a wireless connection module and a micro control unit. A battery holder 902 is installed at the bottom of the controller 9.

[0061] The upper and lower surfaces of the push end sleeve 4 are provided with grooves 403, and the size of the grooves 403 corresponds to the width of the rope 101 fixing buckle and the connecting block 506.

[0062] The set lead screw 401 motor mainly drives the lead screw 401 to rotate, so that the lead screw 401 will rotate at the lead screw nut 402 after rotating, so that the thread at the center of the lead screw nut 402 moves towards the fixed clamp 7 with the rotation of the lead screw 401, causing the entire push end sleeve 4 to move; the upper and lower sides of the end of the motor housing 5 are respectively provided with rope 101 fixing buckle and connecting block 506, so that the sliding groove 403 on the upper and lower surfaces of the push end sleeve 4 can limit the push end sleeve 4, so that the axial rotation of the entire push end sleeve 4 can be limited, and the length of the sliding groove 403 also prevents the movement range of the push end sleeve 4 from leaving the motor housing 5, so that the movable clamp 6 can be directly pushed by the axial push of the push end sleeve 4;

[0063] The rope 101 fixing buckle can also fix the rope 101; the bottom connecting block 506 is further equipped with a controller 9, and the wireless connection module inside the controller 9 is used to connect to the control terminal 103. Therefore, the user can directly control the lead screw 401 motor or the drive motor 502 based on the control terminal 103.

[0064] The drive motor 502 transmits power to the connecting screw 503. The inner wall of the screw slot 302 has threads, which can be screwed together with the connecting screw 503. When the drive motor 502 rotates forward, it will drive the connecting screw 503 to rotate and enter the screw slot 302. When the motor rotates in reverse, it will drive the connecting screw 503 to rotate in the opposite direction and exit the screw slot 302. Before installation, the connecting screw 503 and the screw slot 302 are in a fixed state. After the movable clamp 6 and the fixed clamp 7 have formed a clamping function for the wire 104, the drive motor 502 can make the connecting screw 503 exit from the screw slot 302, realizing the separation between the motor housing 5 and the docking sleeve 3. After the left and right end stroke pushing components complete the clamping operation, they will detach from the spacer bar 102 along with the UAV 1. This reduces the overall load-bearing strength of the wire 104, and its structure can be reused. At the same time, it also prevents the placement of excess structure near the spacer bar 102, which may cause long-term corrosion and rust, leading to parts falling off.

[0065] In one implementation, such as Figure 7-8 As shown, the bottom of the lifting ring 8 extends through to the upper inner side of the movable clamp 6. A one-way wedge 801 is fixedly installed at the bottom of the lifting ring 8. A connecting piece 802 is installed at the top of the movable clamp 6. A spring 803 is installed between the one-way wedge 801 and the connecting piece 802. The one-way wedge 801 and the one-way rack 301 are arranged vertically in correspondence.

[0066] The upper outer wall of the connecting sleeve 3 has a one-way rack 301, and the upper interior of the movable clamp 6 is equipped with a one-way wedge 801. The one-way wedge 801 can move horizontally in one direction on the one-way rack 301. The lower end of the lifting ring 8 is fixed to the one-way wedge 801, and under the action of the spring 803, the one-way wedge 801 naturally fits tightly against the one-way rack 301. If it is necessary to move the one-way wedge 801 in the opposite direction, the lifting ring 8 can be lifted, the spring 803 will be shortened by force, and the one-way wedge 801 will be lifted upward, thus moving in the opposite direction and driving the movable end of the wire clamp to move.

[0067] Its structure allows the entire spacer bar 102 to be disassembled simply by operating the lifting ring 8 to loosen the movable clamp 6, without having to reconnect to the installation structure in the above embodiment. Since there is no need to perform a reverse process operation, the entire spacer bar 102 can be quickly detached from the wire 104 during disassembly.

[0068] In one implementation, such as Figure 9 As shown, a coupling 10 and a bearing 11 are installed between the lead screw 401 and the rotary motor 501. The bearing 11 is sleeved in the middle of the coupling 10. The bearing 11 is used to fix the lead screw 401. The coupling 10 is used to connect and fix the rotary motor 501 and the lead screw 401, so that the overall component can stably transmit the rotary motor 501 to the lead screw 401 at the connection point.

[0069] In one implementation, such as Figure 4 As shown, rubber pads 12 are provided on the inner sides of both the movable clamp 6 and the fixed clamp 7. The movable clamp 6 is used to move unidirectionally toward the fixed clamp 7. The bottoms of both the movable clamp 6 and the fixed clamp 7 are concave curved structures.

[0070] Its curved structure allows the movable clamp 6 to move downward along the curved surface structure at the rubber pad 12 when the distance of the movable clamp 6 from the single rack is insufficient, after the drone 1 continues to pull upward, until the distance between the movable clamp 6 and the fixed clamp 7 expands, satisfying the distance requirement for the wire 104 to detach from the fixed clamp 7 and the movable clamp 6.

[0071] In one implementation, such as Figure 10 As shown, the spacer sleeve 105 is fitted onto the surface of the docking sleeve 3, the fixing clamp 7 and the docking sleeve 3 are fixedly connected by bolts, the docking sleeve 3 and the spacer sleeve 105 are fixedly connected by bolts, and the pushing end sleeve 4 is fitted onto the surface of the motor housing 5.

[0072] Its structure allows multiple rods to be nested together and fixed with bolts to form a long rod structure; because when it is disassembled to the ground later, whether for maintenance or repair, some parts of the structure can be disassembled and repaired or reassembled separately.

[0073] In one implementation, such as Figure 11-13 As shown, a fixing pin 303 is installed on the bottom side of the screw slot 302, and an anti-disengagement block 304 is installed on one end of the fixing pin 303, and the anti-disengagement block 304 is located at the bottom of the motor mounting bracket 504.

[0074] The bottom of the anti-detachment block 304 is provided with a strip-shaped hole structure, and the fixing screw 303 passes through the anti-detachment block 304;

[0075] After the disassembly of the two-end assembly and disassembly structure 2, since the motor housing 5 is detached, the motor fixing clamp 7 does not form a clamping effect on the anti-detachment block 304 with the docking sleeve 3. The anti-detachment block 304 can move downward due to gravity based on the central strip-shaped hole structure until it is mounted on the fixing pin 303, forming a limiting effect on the movable clamp 6 from the bottom of the docking sleeve 3.

[0076] Therefore, when the lifting ring 8 is pulled, the movable clamp 6 and the one-way rack disengage, and even if the movable clamp 6 moves outward, it will not fall to the outside. Figure 3-4 As shown, the cross section of the docking sleeve 3 is the same as that of the motor housing 5, and both have a flat surface at the top. The inner side of the movable clamp 6 is also in clearance fit with the docking sleeve 3 or the motor housing 5. Therefore, when the movable clamp 6 rotates axially, the flat surface fitting structure at the top will form a rotation limit to prevent the movable clamp 6 from rotating radially. This ensures that when the upper lifting ring 8 is under tension, the anti-detachment block 304 is always at the bottom.

[0077] Workflow: First, connect one end of rope 101 to drone 1 and the other end to rope 101 fixing buckle. Drone 1 carries the entire set of spacer bar 102 deployment and installation tools to the vicinity of wire 104. When wire 104 approaches fixing clamp 7, control terminal 103 controls rotary motor 501 to rotate based on controller 9. At this time, push end sleeve 4 will push movable clamp 6 closer to fixing clamp 7 until movable clamp 6 and fixing clamp 7 clamp wire 104 tightly.

[0078] When the movable clamp 6 and the fixed clamp 7 are in the clamping state, the drive motor 502 is remotely driven by the control terminal 103. The reverse rotation of the drive motor 502 will drive the connecting screw 503 to rotate in the opposite direction, thereby exiting the screw slot 302. Thus, this process realizes the disassembly process of the assembly and disassembly structure 2 and the spacer 102 main body.

[0079] During the disassembly process: First, connect one end of rope 101 to drone 1 and the other end of rope 101 to hook. Fly the hook of drone 1 to the vicinity of the lifting ring 8. Lift the lifting ring 8 upward through the hook. Then, the one-way wedge 801 and the one-way rack 301 will separate. The main body of spacer 102 can be lifted from the wire 104. Drone 1 carries the main body of spacer 102 away.

[0080] This invention utilizes the combined application of drones and assembly / disassembly structures: by using drones equipped with specialized tools such as fixing clips, movable clips, and docking sleeves, the spacer bars can be quickly suspended and deployed, avoiding prolonged high-altitude operations by the drone and reducing its weight load; and in conjunction with a rope-fixing device, it enhances stability and safety.

[0081] This invention includes spacer bars, connecting sleeves, and wire clamps, which can automatically adjust the working mode and deployment accuracy according to different operating environments to ensure accurate installation of the spacer bars. It adopts a clamp-type wire clamp design, providing a fast and stable connection method that can adapt to the requirements of different power facilities.

[0082] This invention is based on a one-way rack and one-way wedge mechanism, which enables quick docking. The sleeve is designed with a one-way rack to effectively control the precise positioning of the wire clamp during installation. The application of the one-way wedge ensures the stability of the spacer bar installation and prevents components from falling off or becoming misaligned due to improper operation.
