Technical Field
[0001] This invention relates to the field of power line erection technology, and more specifically, to an intelligent obstacle crossing device for power transmission line erection. Background Technology
[0002] Overhead lines mainly refer to power transmission lines that are erected on the ground and whose transmission conductors are fixed to towers with insulators to transmit electrical energy. Overhead lines are relatively easy to install and maintain, and have lower costs. However, when erecting power transmission lines, there may be obstacles between the towers, which requires obstacle crossing equipment to allow the power transmission lines to cross obstacles during the erection process.
[0003] For example, a Chinese patent disclosed in patent number CN208142716U proposes a crossing device for power transmission line erection. The device uses a servo motor to drive the rotating base to rotate at a certain angle, and the telescopic frame extends outward under the drive of the telescopic cylinder until the counterweight blocks cross the obstacle to the other side. Then, the counterweight blocks can pull the cable line down to cross the obstacle to the other side. The crossing operation is achieved by setting a rotating frame on the lifting platform. The structure is simple and compact, and the operation is reliable.
[0004] In the aforementioned prior art, when erecting power transmission lines, the position of the power transmission line is changed by rotating and bending the telescopic frame, and one end of the power transmission line is crossed over an obstacle by rotating the telescopic frame. However, the distance that this method can cross over an obstacle depends on the length of the telescopic frame and the range of rotation, and thus the number of obstacles that can be crossed is relatively limited.
[0005] Meanwhile, after crossing the obstacle, it is inconvenient for workers to erect power lines, so they fix the power lines to the power poles, which makes the existing technology inconvenient to operate and use. In addition, the obstacle crossing equipment has a low level of intelligence. Summary of the Invention
[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide an intelligent obstacle crossing device for power transmission line erection, thereby solving the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent obstacle crossing device for power transmission line erection, comprising a lifting vehicle 1 and a lifting vehicle 2, wherein an auxiliary moving component for assisting the power line to move in the air is fixedly installed on the top of the lifting vehicle 1, and a drone is placed on the top of one side of the lifting vehicle 2, and a guide rope 1 for guiding the dragged power line to cross the obstacle is movably installed on the top of the auxiliary moving component.
[0008] One end of the guide rope is fixedly installed with a connecting component, and the guide rope is fixedly connected to the second guide rope through the connecting component. One end of the second guide rope is fixedly connected with a connecting plate, and a cable is installed on one side of the connecting plate through the connecting component. A winding component for winding the guide rope and the second guide rope is fixedly installed on the top of one side of the lifting vehicle, and a limiting component for limiting the cable is provided on the top of the winding component.
[0009] The drone moves the guide rope one from the top of the lifting vehicle two to the top of the lifting vehicle two, and winds up the guide rope one through the winding assembly. This causes the guide rope one and the guide rope two, which are fixed by the connecting assembly, to be dragged and wound up in sequence. At the same time, since the guide rope two is fixed to the cable through the connecting assembly, the cable, i.e. the power transmission line, moves and is erected in the air, and successfully crosses the bottom obstacle.
[0010] In a preferred embodiment, the auxiliary moving component includes a fixed frame, which is fixedly installed on the top platform of the lifting vehicle. A drive motor is fixedly installed on the bottom top side of the fixed frame, and the shaft of the drive motor is rotatably connected to a shaft via a connecting belt.
[0011] The outer wall of the shaft is fixedly connected to a roller, and the shaft is rotatably installed inside the fixed frame through a bearing. The top platform of the lifting vehicle is symmetrically equipped with a sliding plate, and the sliding plate is inclined on both sides of the fixed frame. The top inner side of the fixed frame is fixedly connected to a baffle, and the side of the baffle is an arc-shaped structure.
[0012] In a preferred embodiment, the top of the second lifting vehicle is equipped with the same auxiliary moving component as the top of the first lifting vehicle.

The first and second lifting vehicles are placed on either side of the obstacle during use.
[0013] In a preferred embodiment, the connecting assembly includes a double-layered cylinder, and a threaded plate is fixedly connected inside the double-layered cylinder. The threaded plate is installed at equal intervals inside the double-layered cylinder and is fixedly connected to one end of the guide rope.
[0014] The double-layer cylinder has fixed holes at equal intervals on one side. One end of the guide rope is fixedly installed with a fixed cylinder, and one end of the fixed cylinder is fixedly connected with a connecting column. A threaded outer cylinder is movably provided outside the connecting column, and a threaded plate is threadedly connected to the inner wall of the threaded outer cylinder.
[0015] In a preferred embodiment, a pressing plate is fixedly connected to one side of the threaded plate 2.

One side of the elastic sheets has a contraction structure.
[0016] The outer side of the elastic sheet of the extrusion plate is fixedly connected with a locking post. After the extrusion plate is extruded into the double-layer cylinder, the locking post is locked inside the fixed hole. The threaded plate two and the threaded plate one are staggered. After the threaded plate two and the threaded plate one move and lock together, they form the entire threaded cylinder and are threadedly connected to the threaded outer cylinder.
[0017] In a preferred embodiment, one end of the second guide rope is fixedly connected to the fixed cylinder, and the other end of the second guide rope is fixedly connected to the double-layer cylinder through a connecting plate. One end of the first guide rope is fixedly connected to the double-layer cylinder, and the other end of the first guide rope is fixedly connected to the fixed cylinder. The second guide rope is fixedly installed to the cable through a connecting assembly.
[0018] In a preferred embodiment, the winding assembly includes a fixed plate, and a fixed box is fixedly installed on one side of the fixed plate. A fixed motor is fixedly installed inside the fixed box, and a drive gear is fixedly connected to one end of the rotating shaft of the fixed motor. A connecting gear meshes with the top of the drive gear, and a rotating column is fixedly connected inside the connecting gear. The rotating column is fixedly installed inside the fixed plate.
[0019] In a preferred embodiment, a take-up shaft is fixedly connected to one side of the drive gear, and a take-up drum is fixedly installed on the outside of the take-up shaft. Limiting plates are fixedly connected to both sides of the take-up drum, and a locking assembly is fixedly installed on one side of the limiting plate. The locking assembly consists of a double-layer cylinder, a threaded plate, and a fixing hole. The bottom of the UAV is also equipped with a locking assembly, and a rotating rod is rotatably installed on one side of the fixing plate.
[0020] In a preferred embodiment, the drone is fixedly installed to one end of the guide rope via a locking assembly. The limiting assembly includes a limiting box, and a rotating gear is rotatably installed inside the limiting box. A toothed belt meshes with the outer wall of the rotating gear, and a movable column is fixedly connected to the bottom of the toothed belt.
[0021] The movable column is externally equipped with a movable plate, which is movable inside the limiting box. The bottom of the movable plate is fixedly connected to a guide plate, which is movable inside the bottom inner wall of the limiting box.
[0022] In a preferred embodiment, the guide plate is moved without contact on the top of the take-up drum, and the top of the rotating gear is connected to a gear one via a shaft column. The outer wall of the gear one meshes with a gear two, and a linkage rod is fixedly connected to one side of the gear two. The linkage rod is rotatably connected to the rotating column of the connecting gear via a connecting belt, and a fixing box is rotatably connected to the outside of the linkage rod.
[0023] The technical effects and advantages of this invention are as follows:
[0024] The drone propels the guide rope 1 across the top of the lifting vehicle 2 and the lifting vehicle 1, allowing the guide rope 1 to first cross the obstacles encountered during the power transmission line installation. Simultaneously, the connecting components facilitate the securing of the guide rope 1, guide rope 2, and the cable, making it easier to drag the power transmission line across the obstacle. The drone's flight propels the guide rope 1 across obstacles, facilitating subsequent guidance of the power transmission line across obstacles. This increases the distance the obstacle crossing device can cover, making it easier to pull heavier power lines and improving its applicability. Furthermore, controlling the drone's flight allows for controlled obstacle crossing of the power transmission line, enhancing the intelligence of the obstacle crossing device and reducing the need for manual labor.
[0025] By using the connecting components, it is convenient to install and fix the guide rope 1, guide rope 2 and cable, and to fix one end of the guide rope 1 to the winding component and the drone. Since the connection between the guide rope and the obstacle crossing equipment is a unified method, it is convenient for users to operate and reduce the difficulty of operation for workers. At the same time, the use of the connecting plate makes it convenient to move two power lines simultaneously with the two connecting components, which facilitates the simultaneous erection of multiple power lines and improves the working efficiency of the intelligent obstacle crossing equipment. In addition, the lifting vehicle 1 is placed behind the tower where the power lines are erected, which makes it convenient for the power lines to pass through the power line tower in the air, and makes it convenient for workers to erect and fix the power lines.
[0026] By placing lifting vehicle one and lifting vehicle two on either side of the obstacle, the crossing distance of the power transmission line can be adjusted. At the same time, the height of the auxiliary moving component can be easily adjusted by lifting vehicle one and lifting vehicle two, which makes it easy to control the dragging height of the power transmission line by the auxiliary moving component. This facilitates crossing the obstacle and matches the height of the power transmission line erection tower, thereby improving the practicality of the intelligent obstacle crossing equipment. In addition, the rotation of the rollers facilitates the rapid movement of the power transmission line with the winding component, thereby increasing the erection speed of the power transmission line and improving the use value of the intelligent obstacle crossing equipment.
[0027] The use of the winding assembly facilitates the winding of guide ropes one and two, allowing for easy dragging of fixed cables in the air, thus enabling convenient overhead power line installation. Simultaneously, the use of the limiting assembly automatically distributes the wound guide ropes one and two to the left and right, preventing them from becoming tangled and jammed at the same location between the guide ropes and the lifting vehicle, ensuring the normal operation of the winding assembly and the continuous effectiveness of the intelligent obstacle crossing device.
[0028] The push-type sensor transmits a signal to the controller that controls the speed of the drive motor, indicating that the speed of the roller has gradually become less than the winding speed of the take-up drum. As a result, the speed of the drive motor is increased slightly. In this way, the speed of the roller can be automatically adjusted to ensure that the speed of the roller is close to the winding speed of the take-up drum, thus avoiding wear on the guide rope.
[0029] The brush head moves laterally to apply lubricant to the outer roller tube, further reducing sliding wear between the guide rope and the outer roller tube. Simultaneously, when the brush head detaches from the outer roller tube and remains stationary, lubricant from the lubricant reservoir is automatically replenished through the tube body to the brush head, preparing for the next application. This replenishment of lubricant after the brush head detaches from the outer roller tube ensures the brush head is fully wetted before application, guaranteeing even application to the outer roller tube surface, avoiding waste, and ensuring lubricant is present wherever the guide rope passes over the outer roller tube surface, further reducing wear when the guide rope slides against the outer roller tube.

[0044] 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, and 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.
[0045] Example 1:
[0046] according to Figure 1-3 The device shown is an intelligent obstacle crossing device for power transmission line erection, including a lifting vehicle 1 and a lifting vehicle 2 3. The top of the lifting vehicle 1 is fixedly installed with an auxiliary moving component 2 for the aerial movement of the power transmission line. A drone 4 is placed on the top of one side of the lifting vehicle 2 3, and a guide rope 5 for guiding the dragged power transmission line to cross the obstacle is movable on the top of the auxiliary moving component 2.
[0047] The auxiliary moving component 2 includes a fixed frame 21, which is fixedly installed on the top platform of the lifting vehicle 1. A drive motor 22 is fixedly installed on the bottom top side of the fixed frame 21, and the shaft of the drive motor 22 is rotatably connected to a shaft 23 via a connecting belt.
[0048] A roller 24 is fixedly connected to the outer wall of the shaft 23, and the shaft 23 is rotatably installed inside the fixed frame 21 through a bearing. The top platform of the lifting vehicle 1 is symmetrically equipped with a sliding plate 25, and the sliding plate 25 is inclinedly arranged on both sides of the fixed frame 21. A baffle 26 is fixedly connected to the top inner side of the fixed frame 21, and the side of the baffle 26 is an arc-shaped structure.
[0049] More specifically, the implementation method of this embodiment is as follows: The roller 24 is designed to facilitate the movement of the guide rope 5, the guide rope 7 and the cable 11 on the top of the auxiliary moving component 2, thereby facilitating the winding of the winding component 8 to speed up the movement of the transmission line, thereby increasing the speed of the transmission line erection and obstacle crossing, and thus improving the working efficiency of the intelligent obstacle crossing device. The baffle 26 is designed to limit the guide rope 5, the guide rope 7 and the cable 11 to the top of the roller 24, thereby preventing the guide rope and the transmission line from falling down from the side of the roller 24.
[0050] Furthermore, in this embodiment, the top of the second lifting vehicle 3 is equipped with the same auxiliary moving component 2 as the top of the first lifting vehicle 1. One end of the guide rope 5 is fixedly installed at the bottom of the drone 4. The guide rope 5 is movably set on the top of the roller 24. The first lifting vehicle 1 and the second lifting vehicle 3 are placed on both sides of the obstacle when in use.
[0051] More specifically, by placing lifting vehicle 1 and lifting vehicle 2 3 on both sides of the obstacle, the crossing distance of the power transmission line can be adjusted. At the same time, the height of the auxiliary moving component 2 can be easily adjusted by lifting vehicle 1 and lifting vehicle 2 3, which makes it easy to control the dragging height of the power transmission line by the auxiliary moving component 2. This facilitates crossing the obstacle and matches the height of the power transmission line tower, thereby improving the practicality of the intelligent obstacle crossing device.
[0052] Example 2:
[0053] Based on the above embodiments, according to Figure 4-7 The device shown is an intelligent obstacle crossing device for power transmission line erection. One end of the guide rope 5 is fixedly installed with a connecting component 6, and the guide rope 5 is fixedly connected to the guide rope 7 through the connecting component 6. One end of the guide rope 7 is fixedly connected to a connecting plate 10, and a cable 11 is installed on one side of the connecting plate 10 through the connecting component 6.
[0054] More specifically, the implementation method of this embodiment is as follows: the drone 4 moves the guide rope 5 from the top of the lifting vehicle 3 to the top of the lifting vehicle 1, and winds up the guide rope 5 through the winding assembly 8, so that the guide rope 5 and the guide rope 7, which are fixed by the connecting assembly 6, are dragged and wound up in sequence. At the same time, since the guide rope 7 is fixed to the cable 11 through the connecting assembly 6, the cable 11, i.e. the power transmission line, moves and is erected in the air, and successfully crosses the bottom obstacle.
[0055] The diameters of guide rope 5 and guide rope 7 are set to increase sequentially, so that the size of the guide rope can be gradually approached to the size of the power transmission line, thus facilitating the pulling and erection of the power transmission line in the air. At the same time, the number of guide ropes used can be increased according to the size and weight of the power transmission line, and the situation where the drone 4 cannot directly drive the power transmission line is avoided.
[0056] The drone 4 drives the guide rope 5 to cross obstacles, which facilitates the subsequent guidance of power transmission lines to cross obstacles. It also makes it easier to pull heavier power transmission lines while increasing the distance of obstacle crossing, thereby improving the applicability of obstacle crossing equipment. At the same time, by controlling the flight of the drone 4, the power transmission line can be controlled to cross obstacles, which improves the intelligence of the obstacle crossing equipment and reduces the need for manpower.
[0057] It is worth noting that the connection between the guide rope and the obstacle crossing device is a unified method, which facilitates user operation and reduces the difficulty of operation for staff. At the same time, the use of the connecting plate 10 makes it easy to move the two connecting components 6 simultaneously, thereby facilitating the simultaneous erection of multiple power lines and improving the working efficiency of the intelligent obstacle crossing device.
[0058] Combination Figure 7 As shown, in order to facilitate the simultaneous connection and pulling of multiple power transmission lines, one end of the cable 11 is temporarily connected to a part of the connecting component 6, such as the cable 11 being fixedly installed with the fixing cylinder 64. The specific method can be to tie it with a rope or to connect it with a pipe clamp.
[0059] Furthermore, placing the lifting vehicle 1 behind the tower where the power transmission line is erected facilitates the passage of the power transmission line through the tower in the air, making it easier for workers to erect and fix the power transmission line.
[0060] Furthermore, the connecting component 6 in this embodiment includes a double-layer cylinder 61, and a threaded plate 62 is fixedly connected inside the double-layer cylinder 61. The threaded plates 62 are installed at equal intervals inside the double-layer cylinder 61, and the threaded plates 62 are fixedly connected to one end of the guide rope 5.
[0061] The double-layer cylinder 61 has fixed holes 63 at equal intervals on one side. One end of the guide rope 7 is fixedly installed with a fixed cylinder 64, and one end of the fixed cylinder 64 is fixedly connected with a connecting column 65. A threaded outer cylinder 66 is movably provided outside the connecting column 65, and a threaded plate 67 is threadedly connected to the inner wall of the threaded outer cylinder 66.
[0062] A pressing plate 68 is fixedly connected to one side of the threaded plate 67. The pressing plate 68 has a cylindrical structure, and one end of the pressing plate 68 has multiple elastic sheets formed by pressing grooves at equal intervals. One side of the elastic sheet has a contraction structure.
[0063] A locking post 69 is fixedly connected to the outer side of the elastic sheet of the extrusion plate 68. After the extrusion plate 68 is extruded into the double-layer cylinder 61, the locking post 69 is locked inside the fixing hole 63. The threaded plate 67 and the threaded plate 62 are staggered. After the threaded plate 67 and the threaded plate 62 move and lock together, they form the entire threaded cylinder and are threadedly connected to the threaded outer cylinder 66.
[0064] One end of the guide rope 7 is fixedly connected to the fixed cylinder 64, and the other end of the guide rope 7 is fixedly connected to the double-layer cylinder 61 through the connecting plate 10. One end of the guide rope 5 is fixedly connected to the double-layer cylinder 61, and the other end of the guide rope 5 is fixedly connected to the fixed cylinder 64. The guide rope 7 is fixedly installed to the cable 11 through the connecting component 6.
[0065] More specifically, when installing and using the connecting component 6, first insert the extrusion plate 68 into the inside of the double-layer cylinder 61, then align the locking post 69 with the fixing hole 63, and at the same time insert the threaded plate 67 into the inside of the threaded plate 62, forming a complete threaded cylinder structure with the threaded plate 67 and the threaded plate 62. Then, screw the threaded outer cylinder 66 outside the threaded plate 67 and the threaded plate 62, so that the threaded outer cylinder 66 moves outside the connecting post 65, and the threads of the threaded outer cylinder 66 are tightened on the outside of the threaded plate 67 and the threaded plate 62.
[0066] Meanwhile, since the outer diameter of the end of the threaded outer cylinder 66 closer to the extrusion plate 68 is smaller than that of the far end, the outer surface of the threaded outer cylinder 66 has a contracted structure, and the inner diameters at both ends are the same. This facilitates connection with the second threaded plate 67 and the first threaded plate 62. After the threaded outer cylinder 66 enters the extrusion plate 68, it pushes the elastic sheet of the extrusion plate 68 outward, thereby pressing and fixing the elastic sheet between the double-layer cylinder 61 and the threaded outer cylinder 66. At the same time, it pushes the locking post 69 into the fixing hole 63, thereby facilitating the installation and fixing of the connecting components 6.
[0067] Example 3:
[0068] Based on the above embodiments, according to Figure 1 , Figure 8 and Figure 9 The device shown is an intelligent obstacle crossing device for power transmission line erection. A winding assembly 8 for winding guide rope 1 and guide rope 2 7 is fixedly installed on the top of one side of the lifting vehicle 1, and a limiting assembly 9 for limiting the power line is provided on the top of the winding assembly 8.
[0069] More specifically, the implementation method of this embodiment is as follows: the winding component 8 is designed to facilitate the winding of guide rope 1 5 and guide rope 2 7, thereby facilitating the dragging of the fixed cable 11 in the air, which in turn facilitates the overhead installation of the power transmission line. At the same time, with the cooperation of the limiting component 9, the winding guide rope 1 5 and guide rope 2 7 are automatically arranged to the left and right, thereby avoiding the situation where the guide ropes are tangled and piled up at the same position and squeezed and jammed between them and the lifting vehicle 1, thus ensuring the normal use of the winding component 8.
[0070] The winding assembly 8 includes a fixed plate 81, and a fixed box is fixedly installed on one side of the fixed plate 81. A fixed motor 82 is fixedly installed inside the fixed box, and a drive gear 83 is fixedly connected to one end of the shaft of the fixed motor 82. A connecting gear 84 meshes with the top of the drive gear 83, and a rotating column is fixedly connected inside the connecting gear 84. The rotating column is fixedly installed inside the fixed plate 81.
[0071] A take-up shaft is fixedly connected to one side of the drive gear 83, and a take-up drum 85 is fixedly installed on the outside of the take-up shaft. Limiting plates 86 are fixedly connected to both sides of the take-up drum 85, and a locking assembly 87 is fixedly installed on one side of the limiting plate 86. The locking assembly 87 consists of a double-layer cylinder 61, a threaded plate 62, and a fixing hole 63. The locking assembly 87 is also installed on the bottom of the UAV 4. A rotating rod 88 is rotatably installed on one side of the fixing plate 81.
[0072] The drone 4 is fixedly installed to one end of the guide rope 5 via the locking assembly 87. The limiting assembly 9 includes a limiting box 91, and a rotating gear 92 is rotatably installed inside the limiting box 91. A toothed belt 93 meshes with the outer wall of the rotating gear 92, and a moving column 94 is fixedly connected to the bottom of the toothed belt 93.
[0073] The movable column 94 is externally provided with a movable plate 95, and the movable plate 95 is movable inside the limiting box 91. The bottom of the movable plate 95 is fixedly connected with a guide plate 96, and the guide plate 96 is movable inside the bottom inner wall of the limiting box 91.
[0074] The guide plate 96 is moved without contact and is set on the top of the take-up drum 85. The top of the rotating gear 92 is connected to the gear 1 97 through the shaft column. The outer wall of the gear 1 97 is meshed with the gear 2 98. A linkage rod 99 is fixedly connected to one side of the gear 2 98. The linkage rod 99 is rotatably connected to the rotating column of the connecting gear 84 through the connecting belt. A fixing box is rotatably connected to the outside of the linkage rod 99.
[0075] The locking component 87 is designed to fix one end of the guide rope 5 to one side of the winding component 8, which facilitates the winding of the guide rope 5 when the winding drum 85 rotates. The winding of the guide rope 5 also facilitates the movement of the guide rope 7 on the top of the auxiliary moving component 2, and at the same time facilitates the movement of the cable 11 on the top of the auxiliary moving component 2. This makes it easier for the power transmission line to cross obstacles and facilitates the erection of the power transmission line.
[0076] More specifically, during the winding of guide rope 5, the rotation of the drive gear 83 drives the connecting gear 84 to rotate, which in turn drives the linkage rod 99 through the connecting belt, causing gear 2 98 to drive gear 1 97 and rotating gear 92 to rotate. At the same time, the toothed belt 93 moves inside the moving column 94 and moves it left and right, causing the guide plate 96 to swing and wind guide rope 5 left and right, thereby preventing guide rope 5 from accumulating on one side of the winding drum 85. After guide rope 5 is wound up, guide rope 2 7 is moved on top of the auxiliary moving component 2 to wind guide rope 2 7.
[0077] Example 4:
[0078] Combination Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the rotation of the take-up drum 85 and the rotation of the roller 24 are driven by separate motors. The take-up drum 85 is used to wind up the guide rope. As the diameter of the guide rope increases when it winds onto the take-up drum 85, the length of the guide rope will increase accordingly when the take-up drum 85 rotates through the same angle. In other words, the winding speed of the take-up drum 85 will gradually increase. If the roller 24 maintains its original speed, the guide rope passing over the surface of the roller 24 will inevitably slide relative to the roller 24, resulting in sliding friction. Since the cable 11 pulled by the guide rope is usually heavy, the guide rope must be in a taut state for a long time during winding. The long-term sliding friction will inevitably break the taut guide rope, causing the cable 11 to fall and causing a safety accident.
[0079] Based on this, in this embodiment, an outer roller tube 31 is sleeved on the surface of the roller 24, a groove is opened on the surface of the roller 24, a spring 32 is fixedly connected to the groove wall, a locking block 33 is fixedly connected to the end of the spring 32, a locking groove 34 for locking the locking block 33 is opened on the inner wall of the outer roller tube 31, and a pressing sensor 35 is provided in the groove.
[0080] More specifically, combining Figure 10 As shown, when the drum 24 rotates, the contact relationship between the side plane of the locking block 33 and the groove wall of the locking groove 34 allows the outer roller tube 31 to rotate counterclockwise smoothly and synchronously, thereby assisting the movement of the guide rope and facilitating the winding of the take-up drum 85.
[0081] As the winding speed increases and the guide rope slides relative to the drum 24, the guide rope rests on the surface of the outer roller tube 31, causing the outer roller tube 31 to rotate further counterclockwise relative to the drum 24. During this process, the abutting action between the inclined side of the locking block 33 and the groove wall of the locking groove 34 causes the locking block 33 to engage in the groove of the next locking groove 34. Thus, the locking block 33 will first retract into the groove, thereby touching the pressing sensor 35. The pressing sensor 35 transmits a signal to the controller that controls the speed of the drive motor 22, indicating that the speed of the drum 24 has gradually become less than the winding speed of the take-up drum 85. Therefore, the speed of the drive motor 22 is increased slightly, thus automatically adjusting the speed of the drum 24 to ensure that the speed of the drum 24 is approximately the winding speed of the take-up drum 85, avoiding wear on the guide rope.
[0082] Example 5:
[0083] Combination Figures 11-13 As shown, a back plate 36 is fixedly connected to the surface of the fixed frame 21. An L-shaped groove 37 is opened on the surface of the back plate 36. A slider 38 is slidably connected to the groove wall of the L-shaped groove 37. A column 39 is fixedly connected to the surface of the slider 38. An inclined slide frame 40 is slidably connected to the surface of the column 39. A piston rod 41 is fixedly connected to the upper surface of the slider 38. A piston cylinder 42 is provided at the upper end of the piston rod 41. A lubricating oil storage cylinder 43 is fixedly connected to the side of the piston cylinder 42. A one-way valve 44 is fixedly connected between the lubricating oil storage cylinder 43 and the piston cylinder 42. A two-way valve 45 is fixedly connected to the side of the lubricating oil storage cylinder 43.
[0084] A slide rod 46 is fixedly connected to the top of the back plate 36. A sleeve block 47 is slidably sleeved on the surface of the slide rod 46. A brush head 48 is fixedly connected to the upper surface of the sleeve block 47. The lower surface of the sleeve block 47 is fixedly connected to the upper surface of the piston cylinder 42. A tube body 49 is fixedly connected between the one-way valve 45 and the brush head 48.
[0085] A reciprocating screw 50 is rotatably connected to one side of the fixed frame 21. A reciprocating sleeve 51 is sleeved on the surface of the reciprocating screw 50. The upper surface of the reciprocating sleeve 51 is fixedly connected to the lower surface of the inclined slide frame 40. Both the end of the reciprocating screw 50 and the end of the shaft 23 are provided with spur gears 52, and the two spur gears 52 mesh with each other.
[0086] More specifically, when the drum 24 rotates, it will synchronously drive the reciprocating screw 50 to rotate via the shaft 23 and the spur gear 52. The rotation of the reciprocating screw 50, through its cooperation with the reciprocating sleeve 51, will drive the reciprocating sleeve 51 and the inclined slide frame 40 to reciprocate.
[0087] When the inclined sliding frame 40 reciprocates, the column 39 is slidably connected to the inclined sliding frame 40, allowing the slider 38 to slide along the trajectory of the L-shaped groove 37, specifically switching back and forth between horizontal and vertical directions. Thus, when the slider 38 moves horizontally, the piston rod 41, piston cylinder 42, and sleeve block 47 drive the brush head 48 to move horizontally to apply lubricating oil to the outer roller tube 31, further reducing sliding wear between the guide rope and the outer roller tube 31. Simultaneously, when the slider 38 moves vertically, the brush head 48 disengages from the outer roller tube 31 and moves to one side, remaining stationary. The piston rod 41, relative to... After the piston cylinder 42 moves down and then moves up to reset, the lubricating oil in the lubricating oil storage cylinder 43 is automatically replenished to the brush head 48 through the tube body 49 via the one-way valve 44 and the two-way valve 45, preparing for the next application. Moreover, the lubricating oil is replenished after the brush head 48 is separated from the outer roller tube 31. This ensures that the brush head 48 is fully wetted with lubricating oil before application, ensuring uniformity of the application on the surface of the outer roller tube 31, avoiding waste, and ensuring that there is lubricating oil wherever the guide rope passes over the surface of the outer roller tube 31, further reducing wear when the guide rope slides on the outer roller tube 31.
[0088] The working principle of this invention is as follows: First, the lifting vehicle 1 and the lifting vehicle 2 3 are moved and placed on both sides of the obstacle. At the same time, the lifting vehicle 1 is placed on the rear side of the power transmission tower on one side of the obstacle. Then, the lifting vehicle 1 and the lifting vehicle 2 3 are raised and lowered at the same time until the auxiliary moving component 2 reaches the power transmission tower where the power transmission line is erected. Then, the extrusion plate 68 and other structures at one end of the guide rope 5 are inserted into the double-layer cylinder 61 at the bottom of the drone 4. Then, one end of the guide rope 5 is fixed to the bottom of the drone 4.
[0089] like Figure 3The drone 4 is controlled to fly to the top of the second elevator 3, and then fly towards the first elevator 1, so that the guide rope 5 is driven to cross between the second elevator 3 and the first elevator 1. At the same time, the drone 4 is flown to the position of the winding component 8 and the limiting component 9 on the side of the first elevator 1. Then the drone 4 is stopped, the guide rope 5 is disassembled through the connecting component 6, and then the squeezing plate 68 at one end of the guide rope 5 is reinserted into the locking component 87, thereby fixing one end of the guide rope 5 to the side of the limiting plate 86. Then, by using the fixed motor 82, the winding drum 85 is rotated, and the guide rope 5 is wound up.
[0090] Before winding, the other end of guide rope 1 5 is installed and fixed to guide rope 2 7 through connecting component 6. Then, the rear end of guide rope 2 7 is fixed to cable 11 through connecting plate 10 and connecting component 6. When winding guide rope 1 5, guide rope 2 7 is pulled to move on top of auxiliary moving component 2. At the same time, drive motor 22 drives shaft 23 to rotate, so that roller 24 rotates to assist in conveying guide rope 1 5 at the top. When one end of guide rope 1 5 is wound outside the winding drum 85, it first passes the bottom of rotating rod 88, so that it can be limited by rotating rod 88. At the same time, the rotation of rotating rod 88 facilitates the movement and winding of guide rope 1 5.
[0091] When the guide rope 5 is wound up, the rotation of the drive gear 83 drives the connecting gear 84 to rotate, which in turn drives the linkage rod 99 through the connecting belt, causing the gear 2 98 to drive the gear 1 97 and the rotating gear 92 to rotate. As a result, the toothed belt 93 moves under the rotation of the rotating gear 92, thereby causing the moving column 94 connected to the surface of the toothed belt 93 to move left and right, so that the guide plate 96 swings the guide rope 5 left and right to wind it up, thereby preventing the guide rope 5 from piling up on one side of the winding drum 85. After the guide rope 5 is wound up, the guide rope 2 7 moves on top of the auxiliary moving component 2 and winds up the guide rope 2 7.
[0092] Finally, the cable 11 is moved on top of the auxiliary moving component 2, and then one end of the cable 11 is moved to the position of the power transmission tower. The staff at the tower position then separate the cable 11 from the guide rope 7, and then the cable 11, i.e. the power transmission line, is erected and installed, which also facilitates the crossing of the cable 11 over obstacles.
