[0027] The technical solutions of the present application are described below through specific embodiments.

[0028] Please refer to Figures 1-4 , wherein Figure 1 is a structural schematic diagram of an intelligent pay-off trolley provided by an embodiment of the present application, Figure 2 is another structural schematic diagram of an intelligent pay-off trolley provided by an embodiment of the present application, Figure 3 is a structural schematic diagram of a pay-off pulley block in an intelligent pay-off trolley provided by an embodiment of the present application, Figure 4 is a structural schematic diagram of an intelligent pay-off trolley after removing part of the shell of the pay-off pulley block provided by an embodiment of the present application. As Figures 1-4As shown, the intelligent pay-off trolley specifically comprises a pay-off trolley support 100, a pulley 200, a pay-off pulley set 300, a camera holder 400, a pay-off guide rail set 500, and an electrical cabinet 600; the pulley 200 is movably connected to the pay-off trolley support 100; both ends of the pay-off pulley set 300 are connected to the pay-off trolley support 100, for conveying the cable traction line from the outside to the inside of the intelligent pay-off trolley; one end of the pay-off guide rail set 500 is fixed to the pay-off pulley set 300, and the pay-off guide rail 530 in the pay-off guide rail set 500 can rotate under the action of a driving force to switch between the unfolded state and the storage state; the camera holder 400 is fixedly arranged on the pay-off pulley set 300; the electrical cabinet 600 is fixedly arranged on the pay-off trolley support 100; wherein the second pay-off pulley 330 in the pay-off pulley set 300 is movably connected to the retainer 310 through the double-sided limiting structure 340 arranged on the retainer 310 in the pay-off pulley set 300, and the second pay-off pulley 330 can be driven by the first pay-off pulley 320 arranged in the retainer 310 to rotate synchronously for traction line conveying; one end of the double-sided limiting structure 340 in contact with the second pay-off pulley 330 is a plurality of follow-up pulleys (not shown).

[0029] In the present embodiment, in the process of installing the conductor in the power grid line construction, the threading of the traction line (which can also be understood as a guide rope, a traction rope, etc.) can be performed by the intelligent pay-off trolley in the present application, and the cable is connected behind the traction line. The root of the cable needs to be finally connected to the traction machine, and the end of the cable is initially on the cable reel and can be specifically payed off by the pay-off machine. Specifically, a plurality of power towers are arranged on a power grid line construction site, and when it is necessary to lay cables on the plurality of power towers, the above-mentioned plurality of power towers need to be pulled through first, and the intelligent pay-off trolley in the present application can be fixedly arranged at the top of each power tower.

[0030] Taking the threading process of one of the intelligent wire-laying pulleys as an example, after fixing the wire-laying pulley support 100 to a designated position on the top of the power tower, a drone is then operated to carry the traction line through the wire-laying groove on the second wire-laying pulley 330 in the wire-laying pulley assembly 300 (the initial position of the wire-laying groove is facing outwards from the intelligent wire-laying pulley). The camera gimbal 400 can capture images of whether the traction line has passed through the wire-laying groove on the second wire-laying pulley 330. After completing the above threading process, the second wire-laying pulley 330 needs to be rotated to transport the traction line from the outside to the inside of the intelligent wire-laying pulley. The drone then continues to carry the traction line to perform the threading operation on the next intelligent wire-laying pulley on the power tower. At this point, after the threading operation is completed and the traction line is transported from the outside to the inside of the intelligent wire-laying trolley, the cable connected to the traction line moves within the space formed by the wire-laying trolley support 100 and the pulley 200. This movement is primarily driven by the friction between the cable and the pulley 200, causing the pulley 200 to rotate simultaneously. The electrical cabinet 600 is equipped with a controller and a communication module. The controller can control the wire-laying pulley assembly 300, the camera gimbal 400, and the wire-laying guide rail assembly 500. The communication module can establish a communication connection with the drone. The wire-laying guide rail assembly 500 must be in a retracted state (i.e., in contact with the wire-laying trolley support 100) during the process of transporting the intelligent wire-laying trolley from the ground to the top of the power tower for installation. After the intelligent wire-laying trolley has been transported and placed on top of the power tower, the wire-laying guide rail assembly 500 can be switched to an unfolded state to serve as an auxiliary structure for the wire-threading process. Specifically, a drone can first carry the traction line and fly over the wire-laying guide rail assembly 500, allowing the traction line to attach to the wire-laying guide rail assembly 500 under its own weight. Then, the traction line slides down the slope of the wire-laying guide rail assembly 500 into the wire-laying groove on the second wire-laying pulley 330. Finally, the second wire-laying pulley 330 is rotated to transport the traction line from the outside to the inside of the intelligent wire-laying trolley. Moreover, during the process of the second wire-laying pulley 330 transporting the traction line from the outside to the inside of the intelligent wire-laying trolley, a double-sided limiting structure limits and guides the rotation of the second wire-laying pulley. It can be seen that by movably connecting the second wire-feeding pulley in the wire-feeding pulley block to the retaining member through a double-sided limiting structure, and by setting a number of follower pulleys at one end of the double-sided limiting structure that contacts the second wire-feeding pulley, the friction mode between the second wire-feeding pulley and the double-sided limiting structure can be effectively changed to rolling friction, which effectively reduces the wire-feeding pulley jamming caused by corrosion.

[0031] In some embodiments, such as Figure 1 As shown, the line-feeding trolley support 100 includes a first support 110, a second support 120, and a first connector 130; the top end of the first support 110 is connected to the top end of the line-feeding pulley assembly 300 through the first connector 130; the top end of the second support 120 is connected to the bottom end of the line-feeding pulley assembly 300.

[0032] In the embodiment, as the overall support structure of the intelligent pay-off trolley, it can be at least provided with the first support 110, the second support 120 and the first connecting piece 130, wherein the height of the first support 110 is greater than the height of the second support 120, and after the top end of the pay-off pulley block 300 is connected to the top end of the second support 120, the total height thereof is substantially equal to the height of the first support 110, and other parts of the intelligent pay-off trolley can be provided on or connected to the pay-off trolley support 100.

[0033] In some embodiments, as shown in Figures 1-4 the pay-off pulley block 300 includes the holding piece 310, the first pay-off pulley 320, the second pay-off pulley 330, the double-sided limiting structure 340 and the coded motor 350; the holding piece 310 includes the lower holding piece 311 and the upper holding piece 312; the coded motor 350 is arranged on the lower holding piece 311; the first pay-off pulley 320 is arranged in the lower holding piece 311 and is sleeved on the rotating shaft of the coded motor 350; one end of the second pay-off pulley 330 is movably connected to the lower holding piece 311, and the second pay-off pulley gear 331 in the second pay-off pulley 330 is engaged with the first pay-off pulley gear 321 in the first pay-off pulley 320, and the other end of the second pay-off pulley 330 is movably connected to the upper holding piece 312.

[0034] In the embodiment, the holding piece 310 is specifically provided with the lower holding piece 311 and the upper holding piece 312, so that the two ends of the second pay-off pulley 330 can be movably connected to the lower holding piece 311 and the upper holding piece 312 through the double-sided limiting structure 340. Since the second pay-off pulley gear 331 in the second pay-off pulley 330 is engaged with the first pay-off pulley gear 321 in the first pay-off pulley 320, when the first pay-off pulley 320 rotates under the drive of the coded motor 350, the second pay-off pulley 330 can be driven to rotate. For example, the pay-off groove on the second pay-off pulley 330 rotates from the direction of the outer side of the intelligent pay-off trolley to the direction of the inner side of the intelligent pay-off trolley under the drive of the first pay-off pulley gear 321 in the first pay-off pulley 320, and the conveying of the traction line from the outer side to the inner side of the intelligent pay-off trolley is realized through this movement mode. Moreover, the second pay-off pulley gear 331 in the second pay-off pulley 330 and the first pay-off pulley gear 321 in the first pay-off pulley 320 are matched through the concave-convex groove, forming the interlocking of the movement plane, ensuring the stable operation of the pulley.

[0035] In some embodiments, as shown in Figure 3 andFigure 4 As shown, the second pay-off pulley 330 comprises the second pay-off pulley gear 331 and the second pay-off pulley guide rail 332; the second pay-off pulley guide rail 332 comprises the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322 which are oppositely arranged; the second pay-off pulley gear 331 is located between the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322; the second pay-off pulley gear 331 is provided with the first pay-off groove 3311, the second pay-off pulley first guide rail 3321 is provided with the second pay-off groove 33211, and the second pay-off pulley second guide rail 3322 is provided with the third pay-off groove 33221; the first pay-off groove 3311, the second pay-off groove 33211 and the third pay-off groove 33221 are oppositely arranged.

[0036] In the embodiment, the second pay-off pulley 330 with the above structure is adopted, so that the first pay-off groove 3311, the second pay-off groove 33211 and the third pay-off groove 33221 are aligned and form a complete pay-off groove, and when the first pay-off pulley gear 321 in the first pay-off pulley 320 drives the second pay-off pulley gear 331 to rotate, the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322 are also driven to rotate synchronously. When the above complete pay-off groove faces the outside of the intelligent pay-off trolley, it is in the stage of waiting for the unmanned aerial vehicle to pass through the traction line. After the unmanned aerial vehicle passes through the pay-off groove while pulling the traction line, the first pay-off pulley gear 321 in the first pay-off pulley 320 drives the entire second pay-off pulley 330 to rotate, so that the pay-off groove faces the inside of the intelligent pay-off trolley. The two pay-off pulleys with gear meshing action can control the opening angle of the pay-off groove, thereby improving the precision of the pay-off operation.

[0037] Moreover, the second pay-off pulley 330 and the first pay-off pulley 320 are interlocked in the movement plane between the upper holding member 312 and the lower holding member 311 through the ingenious design of the guide rail and the gear structure. The above interlocking mechanism is derived from the contact between the second pay-off pulley guide rail 332 of the second pay-off pulley 330 and the guide rail surface of the first pay-off pulley 320, and the concave-convex groove-shaped cooperation formed by the cooperation of the second pay-off pulley gear of the second pay-off pulley 330 and the first pay-off pulley gear 321 of the first pay-off pulley 320 through the gear gap, thereby ensuring the precise interlocking of the second pay-off pulley 330 and the first pay-off pulley 320 in the movement plane.

[0038] In some embodiments, as shown in Figure 3 As shown, the second pay-off pulley gear 331, the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322 are coaxial structures.

[0039] In the embodiment, in order to realize the stable rotation of the second pay-off pulley 330, the second pay-off pulley gear 331, the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322 are coaxial structures, that is, the central axes of the second pay-off pulley gear 331, the second pay-off pulley first guide rail 3321 and the second pay-off pulley second guide rail 3322 are on the same straight line.

[0041] In the embodiment, in order to realize the stable rotation of the second pay-off pulley 330 on the lower holder 311, a lower holder upper recess is arranged on the lower holder 311 and the bottom end of the second pay-off pulley 330 passes through the recess. Moreover, the upper end of the upper half of the lower holder first shell 3111 is provided with a plurality of first follow-up pulleys, and the plurality of first follow-up pulleys are located in the lower holder upper recess; the upper end of the upper half of the lower holder second shell 3112 is provided with a plurality of second follow-up pulleys 342, and the plurality of second follow-up pulleys 342 are located in the lower holder upper recess and face the plurality of first follow-up pulleys. Through this structure, the plurality of first follow-up pulleys and the plurality of second follow-up pulleys 342 are in contact with the two end faces close to the bottom end of the second pay-off pulley gear 331, respectively, and in the application, the sliding friction between the lower double-limiting structure in the double-limiting structure 340 and the contact surface of the second pay-off pulley 330 is changed into rolling friction, effectively reducing the pay-off pulley jamming phenomenon caused by rust.

[0042] In some embodiments, as shown in Figure 3 and Figure 4 the upper holder includes an upper holder first shell 3121 and an upper holder second shell 3122; the lower half of the upper holder first shell 3121 is narrower than the upper half of the upper holder first shell 3121, and the lower half of the upper holder second shell 3122 is narrower than the upper half of the upper holder second shell 3122; the lower half of the upper holder first shell 3121 and the upper holder second shell 3122, when connected, forms an upper holder lower groove (not shown in the figure) for the second pay-off pulley 330 to pass through; the lower half of the upper holder first shell 3121 is provided with a plurality of third follower pulleys (not shown in the figure), and the plurality of third follower pulleys are located in the upper holder lower groove; the lower half of the upper holder second shell 3122 is provided with a plurality of fourth follower pulleys 344, and the plurality of fourth follower pulleys 344 are located in the upper holder lower groove and opposite to the plurality of third follower pulleys; the plurality of third follower pulleys and the plurality of fourth follower pulleys 344 form the upper double-limiting structure of the double-limiting structure 340.

Similarly, through this structure, the plurality of third follower pulleys and the plurality of fourth follower pulleys 344 are in contact with the two end faces close to the top end of the second pay-off pulley gear 331, respectively, and the sliding friction between the upper double-limiting structure of the double-limiting structure 340 and the contact surface of the second pay-off pulley 330 is converted into rolling friction in the present application, effectively reducing the pay-off pulley jamming phenomenon caused by rust.

[0044] In some embodiments, as shown in Figure 3 and Figure 4 the second pay-off pulley guide rail 332 in the second pay-off pulley 330 is located in the first limiting space formed by the lower double-limiting structure and the upper holder lower groove; the second pay-off pulley guide rail 332 in the second pay-off pulley 330 is located in the second limiting space formed by the upper double-limiting structure and the upper holder lower groove.

[0045] In the embodiment, in order to realize the double-side limiting function of the double-side limiting structure, the second pay-off pulley guide rail 332 in the second pay-off pulley 330 is located in the first limiting space formed by the lower double-side limiting structure and the bottom of the upper recess of the lower holder; the second pay-off pulley guide rail 332 in the second pay-off pulley 330 is located in the second limiting space formed by the upper double-side limiting structure and the bottom of the lower recess of the upper holder, so that the top end and the bottom end of the second pay-off pulley 330 are limited in the corresponding limiting space and cannot be separated from the limiting space, ensuring the stability of the movement of the second pay-off pulley.

[0046] In some embodiments, as shown in Figure 1 and Figure 3 The upper holder 312 is further provided with a camera holder connecting seat (not shown), and the camera holder 400 is fixedly arranged on the camera holder connecting seat.

[0047] In the embodiment, the upper holder 312 is further provided with a camera holder connecting seat, and the camera holder 400 is fixedly arranged on the camera holder connecting seat. The camera holder 400 can collect images of the area where the pay-off groove of the second pay-off pulley 330 is located, so as to determine whether the traction line passes through.

[0048] In some embodiments, as shown in Figure 2 and Figure 3 The pay-off guide rail group 500 includes an encoding steering engine 510, a driving connecting rod 520 and a pay-off sliding rail 530; the encoding steering engine 510 is fixedly arranged on the lower holder 311; one end of the pay-off sliding rail 530 is connected to the lower holder 311; one end of the driving connecting rod 520 is connected to the rotating shaft of the encoding steering engine 510, and the other end of the driving connecting rod 520 is connected to the pay-off sliding rail 530, and is used to drive the pay-off sliding rail to rotate when the encoding steering engine 510 drives the driving connecting rod 520 to rotate.

[0049] In the embodiment, the wire laying guide rail set 500 needs to be in the storage state (i.e., in the state of being attached to the wire laying trolley support 100) during the process of transporting the intelligent wire laying trolley from the ground to the top of the power tower for installation. Specifically, the coded steering engine 510 drives the driving link 520 to rotate so that the angle between the end connected to the wire laying rail 530 and the vertical direction is close to 0°. After the intelligent wire laying trolley has been transported and placed at the top of the power tower, the wire laying guide rail set 500 can be switched to the unfolded state to serve as an auxiliary structure during the threading process. Specifically, the coded steering engine 510 drives the driving link 520 to rotate so that the angle between the end connected to the wire laying rail 530 and the vertical direction is greater than 90°. As can be seen, the coded steering engine drives the driving link, and then the wire laying rail completes its pitching action. When transportation is needed, the coded steering engine only needs to be adjusted to zero position, and the folding and storage of the wire laying guide rail set can be easily realized.

[0050] As can be seen, the intelligent wire laying trolley of the present application can movably connect the second wire laying pulley in the wire laying pulley set to the holder through the double-sided limiting structure, and by setting the end of the double-sided limiting structure in contact with the second wire laying pulley as a plurality of follow-up pulleys, the friction mode between the second wire laying pulley and the double-sided limiting structure can be effectively changed to rolling friction, effectively reducing the wire laying pulley jamming phenomenon caused by rust. Through the camera, image information of the state of the power transmission line can be obtained in real time, and linkage with automatic control or remote manual control can be realized, thereby improving the unmanned automation degree of wire laying operation, reducing labor costs, and improving safety.
