Description

Technical Field

[0001] This utility model belongs to the technical field of power system cable laying equipment, and in particular relates to a V-shaped trolley used for laying cables by drones. Background Technology

[0002] In the construction of power distribution lines, cable pulleys are a commonly used cable laying tool. Their main components include pulleys, bases, and connectors. Cable laying is mainly achieved by pulling a steel wire traction rope to move the cable within the cable space inside the pulley, allowing the cable to quickly enter the preset position. Cable pulleys can also provide good support for power supply lines, preventing damage to power cables during the laying process.

[0003] Currently, the most widely used methods for laying cables in power distribution networks include manual cable laying and drone-guided laying. Manual cable laying requires numerous ground preparation steps and high-altitude operations, making the work difficult and inefficient. With the rapid development of drone technology and its penetration into many application scenarios, using drones to replace manual cable laying can solve many of the drawbacks of manual cable laying, greatly improving efficiency and reducing the difficulty of the work.

[0004] However, during high-altitude cable laying operations, the traction rope dragged by the drone in the air presents many unstable and uncontrollable factors, making it difficult for the traction rope to enter the predetermined position of the pulley transmission component. This greatly limits the application performance of drones in cable laying operations, preventing them from fully demonstrating their efficient and rapid application. Utility Model Content

[0005] The purpose of this invention is to provide a V-shaped trolley for cable laying by drones, which aims to solve the problem that the traction rope is difficult to enter the predetermined position of the trolley during the cable laying process of drones.

[0006] To address the aforementioned problems, this utility model provides a V-shaped trolley for cable laying using unmanned aerial vehicles (UAVs), comprising a base, a frame assembly, a pulley assembly, and a guide assembly;

[0007] The base is fixedly disposed at the first end of the frame assembly, the pulley assembly is disposed inside the frame assembly on the side near the base, and the guide assembly is disposed at the second end of the frame assembly;

[0008] The guide assembly includes a first guide portion and a second guide portion. The first guide portion and the second guide portion are arranged in a V-shape. The first guide portion and the second guide portion are provided with a first gap on the side near the frame assembly. The second end of the frame assembly is provided with a second gap. The first gap and the second gap are in communication.

[0009] Preferably, the V-shaped trolley further includes a limiting component, which includes a first limiting part and a second limiting part. The first limiting part and the second limiting part are disposed on the inner side of the second end of the frame component, and a third gap is provided between the first limiting part and the second limiting part, which communicates with the second gap.

[0010] Preferably, the first gap is greater than or equal to the second gap, and the second gap is greater than or equal to the third gap.

[0011] Preferably, the V-shaped trolley further includes an adjustment assembly disposed on the outside of the frame assembly;

[0012] The adjustment assembly includes a support part, a first adjusting bolt, an adjusting ring, and a second adjusting bolt. The support part is fixedly connected to the outside of the frame assembly. The support part is sleeved on the outside of the first adjusting bolt. The side wall of the support part is provided with an adjusting groove. The adjusting ring passes through the adjusting groove and is fixedly connected to the first adjusting bolt. The adjusting ring is provided with a thread inside. The thread is adapted to the second adjusting bolt. The second adjusting bolt is rotatably connected to the adjusting ring. One end of the second adjusting bolt abuts against the outside of the frame assembly.

[0013] Preferably, the frame assembly has two arc-shaped sidewalls, which are symmetrically arranged on the frame assembly and form a circular space between them. The circular space is located between the pulley assembly and the guide assembly, and the adjustment assembly is disposed on the outer side of the arc-shaped sidewalls near the pulley assembly.

[0014] Preferably, the pulley assembly includes a fixing bolt and a roller, the fixing bolt being rotatably connected to the roller and the fixing bolt being fixedly connected to the frame assembly.

[0015] Preferably, the roller is made of insulating epoxy resin material.

[0016] Preferably, the base includes a first mounting plate, a second mounting plate, and a connecting plate. The first mounting plate is fixedly connected to the frame assembly, and the second mounting plate is connected to the first mounting plate through the connecting plate. The second mounting plate is located on the side of the first mounting plate away from the frame assembly.

[0017] Preferably, the connecting plate is disposed on one side of the first mounting plate and the second mounting plate, and an installation space is formed between the first mounting plate and the second mounting plate, the installation space being used to install the V-shaped trolley.

[0018] Preferably, the base further includes mounting bolts, and a through hole is formed on the second mounting plate, the mounting bolts being adapted to the through hole.

[0019] By incorporating a V-shaped first and second guide section at the top of the trolley, the V-shaped trolley is fixed to the cable pre-laying support via a base during UAV cable laying. A larger traction rope inlet is formed at the top of the trolley, allowing the traction rope to smoothly pass between the first and second guide sections and enter the trolley's frame assembly, improving cable laying efficiency and safety. Furthermore, the V-shaped traction rope inlet prevents the traction rope from detaching from the trolley at the bottom after entering the frame assembly, resulting in a smoother cable movement along the traction rope mechanism and further enhancing laying efficiency. Positioning the guide assembly at the top of the trolley allows the traction rope to enter the frame assembly by its own weight, preventing excessive lateral displacement that could cause cable swaying and exacerbate cable vibration during laying. This design effectively improves the stability of the traction rope and the cable during laying, facilitating safer and smoother cable laying. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0032] The accompanying drawings show schematic diagrams of layer structures according to embodiments of the present invention. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0033] Combination Figures 1 to 4 This utility model provides a V-shaped trolley for laying cables for drones, including a base 1, a frame assembly 2, a pulley assembly 3, and a guide assembly 4; the base 1 is fixedly disposed at the first end of the frame assembly 2, the pulley assembly 3 is disposed inside the frame assembly 2 on the side near the base 1, and the guide assembly 4 is disposed at the second end of the frame assembly 2; the guide assembly 4 includes a first guide portion 41 and a second guide portion 42, the first guide portion 41 and the second guide portion 42 are arranged in a V-shape, the first guide portion 41 and the second guide portion 42 are provided with a first gap on the side near the frame assembly 2, and the second end of the frame assembly 2 is provided with a second gap, the first gap and the second gap are connected.

[0034] By setting a V-shaped first guide section 41 and a second guide section 42 on the top of the trolley, the V-shaped trolley is vertically set during the cable laying process by the UAV. The base 1 is located at the bottom of the V-shaped trolley, and the V-shaped trolley is fixed to the cable pre-laying bracket through the base 1. A larger traction rope inlet is formed on the top of the trolley. After the traction rope enters between the first guide section 41 and the second guide section 42, it can smoothly pass through the first gap and the second gap into the frame assembly 2 of the trolley, improving the efficiency and safety of cable laying. In addition, the V-shaped traction rope inlet helps to prevent the traction rope from leaving the trolley along the bottom of the traction rope inlet after entering the frame assembly 2 of the trolley, making the process of the cable along the traction rope machine trolley smoother and improving the cable laying efficiency. Furthermore, by placing the guide component 4 on top of the trolley, the traction rope can use its own weight to enter the frame component 2 of the trolley along the guide component 4, preventing excessive displacement of the traction rope in the left and right directions, which would cause the cable to swing left and right, and avoid aggravating the shaking of the cable during the laying process. This setting can effectively improve the stability of the traction rope and the cable during the cable laying process, and is more conducive to the safe and smooth completion of cable laying.

[0035] It should be noted that the connection method between the guide component 4 and the frame component 2 is not limited here. It can be a fixed connection, such as welding, snap-fit, or screw connection, or the frame component 2 and the guide component 4 can be integrally formed. The specific position of the guide component 4 in the frame component 2 is also not limited; it can be located on one side or in the middle of the top of the frame component 2. In a preferred embodiment, the guide component 4 is positioned at the exact center of the top of the frame component 2. With this arrangement, the first gap and the second gap are located in the middle of the top of the frame component 2. During cable laying, the path of the traction rope entering the frame component 2 is more closely aligned with the vertical direction of the cable installation, reducing the lateral sway of the cable and further improving the stability of the cable laying process.

[0036] Combination Figure 1 and Figure 2 In a preferred embodiment, the V-shaped trolley further includes a limiting component 5, which comprises a first limiting part 51 and a second limiting part 52. The first limiting part 51 and the second limiting part 52 are disposed on the inner side of the second end of the frame assembly 2, and a third gap is provided between the first limiting part 51 and the second limiting part 52, which communicates with the second gap. Specifically, the first limiting part 51 and the second limiting part 52 are located on both sides of the second gap. When the traction rope enters the frame assembly 2, the first limiting part 51 and the second limiting part 52 can effectively restrict the movement path of the traction rope, preventing the traction rope from detaching from the frame assembly 2 due to swaying during the laying process. The specific connection method between the limiting component 5 and the frame assembly 2 is not limited here; it can be screwed, welded, or integrally formed.

[0037] In a preferred embodiment, the first gap is greater than or equal to the second gap, and the second gap is greater than or equal to the third gap. With this configuration, similar to the V-shaped first guide portion 41 and second guide portion 42, when the traction rope enters the frame assembly 2, it relies on gravity to descend and sequentially pass through the first gap, the second gap, and the third gap, smoothly entering the frame assembly 2, thus completing the cable entry into the laying position. The third gap between the limiting components 5 inside the frame can prevent the traction rope or cable from detaching, ensuring smooth cable laying and the safety of the laying process.

[0038] In a preferred embodiment, the V-shaped trolley further includes an adjustment assembly 6, which is disposed on the outside of the frame assembly 2 and located between the pulley assembly 3 and the guide assembly 4. The adjustment assembly 6 includes a support part 61, a first adjusting bolt (62), an adjusting ring (63), and a second adjusting bolt 64. The support part 61 is fixedly connected to the outside of the frame assembly 2 and is sleeved on the outside of the first adjusting bolt 62. The side wall of the support part 61 is provided with an adjusting groove 61a. The adjusting ring 63 passes through the adjusting groove 61a and is fixedly connected to the first adjusting bolt 62. The adjusting ring 63 is provided with a thread inside, which is adapted to the second adjusting bolt 64. The second adjusting bolt 64 is rotatably connected to the adjusting ring 63, and one end of the second adjusting bolt 64 abuts against the outside of the frame assembly 2.

[0039] The first adjusting bolt 62 rotates within the support 61, causing the adjusting ring 63 to deflect along the adjusting groove 61a. This determines the specific orientation and position of the adjusting ring 63 relative to the frame assembly 2. The second adjusting bolt 64 rotates within the adjusting ring 63, causing a change in the length from the point where the second adjusting bolt 64 abuts against the outer side of the frame assembly 2 to the adjusting ring 63. This causes the frame assembly 2 to bend inward, thereby adjusting the first gap and the size of the internal space of the frame assembly 2. Specifically, taking a vertically installed V-shaped trolley as an example, when the cable size is small and the diameter of the traction rope is also small, the first adjusting bolt 62 first drives the adjusting ring 63 to fix its position. In one optional scenario, the position of the adjusting ring 63 is adjusted to the side closer to the base 1. At this time, the second adjusting bolt 64 rotates downward along the adjusting ring 63, increasing the length of the second adjusting bolt 64 between the frame assembly 2 and the adjusting ring 63. The second adjusting bolt 64 presses against the support part 61, causing the frame assembly 2 to deform inward, thereby reducing the first gap and the space inside the frame. In another optional scenario, the first adjusting bolt 62 can also adjust the adjusting ring 63 to rotate along the adjusting groove 61a to the side facing the top of the frame assembly 2. At this time, the second adjusting bolt 64 rotates upward along the adjusting ring 63, increasing the length of the second adjusting bolt 64 between the frame assembly 2 and the adjusting ring 63. The second adjusting bolt 64 presses against the support part 61, causing the frame assembly 2 to deform inward, thereby reducing the first gap and the space inside the frame.

[0040] This design allows the V-shaped pulley to be used with traction ropes and cables of different sizes, improving its versatility. At the same time, the direction of the adjusting ring 63 is set to be adjustable, making the adjustment method more flexible and further enhancing the versatility of the V-shaped pulley.

[0041] It should be noted that the specific fixing method of the end of the second adjusting bolt 64 at the abutment of the frame assembly 2 is not limited here. It can be that a limiting post is set at the frame assembly 2 and the second adjusting bolt 64, and the limiting post and the outer side of the frame assembly 2 abut against the end of the second adjusting bolt 64 together to prevent the second adjusting bolt 64 and the frame assembly 2 from being displaced in the vertical direction of the frame assembly 2 during rotation. Alternatively, a groove is set on the outer side of the frame assembly 2 for the second adjusting bolt 64 to abut against, and one end of the second adjusting bolt 64 abuts against the groove, which can also prevent the second adjusting bolt 64 and the frame assembly 2 from sliding or displacing.

[0042] In a preferred embodiment, the frame assembly 2 has two arc-shaped sidewalls 21, which are symmetrically arranged on the frame assembly 2. A circular space is formed between the two arc-shaped sidewalls 21, located between the pulley assembly 3 and the guide assembly 4. The adjusting assembly 6 is located on the outer side of the arc-shaped sidewalls 21 near the pulley assembly 3. During cable laying, the traction rope often needs to be looped around the cable. The diameter of the connection point between the traction rope and the cable is often larger than the diameter of the cable. Forming a circular space inside the frame assembly 2 facilitates the smooth passage of the cable and traction rope connection point through the frame assembly 2, preventing the frame assembly 2 from obstructing the traction rope or cable end, thus avoiding cable laying obstruction or traction rope detachment. This improves the efficiency and safety of cable laying. The distance between the circular space and the pulley assembly 3 is not limited here. The circular space can be closely positioned above the pulley assembly 3, so that when the cable slides on the pulley assembly 3, the cable is exactly within the circular space, which is beneficial for laying larger cables. Alternatively, there can be a straight-line distance between the circular space and the pulley assembly 3, so that when the cable size is small, the cable only slides on the pulley assembly 3, ensuring the stability of the cable laying. The specific location of the adjusting component 6 on the outside of the frame assembly 2 is not limited here. The support part 61 can be on the outside of the arc-shaped sidewall 21, or on the straight sidewall of the frame assembly 2 between the arc-shaped sidewall 21 and the pulley assembly 3. The adjusting component 6 only needs to be able to adjust the internal space and the first gap of the frame assembly 2. Simultaneously, the adjusting component 6 can also adjust the size of the circular space, so that cables of different diameters have suitable room to move during laying, enabling the V-shaped trolley to more efficiently transmit the traction rope and cable.

[0043] In a preferred embodiment, the pulley assembly 3 includes a fixing bolt 31 and a roller 32. The fixing bolt 31 is rotatably connected to the roller 32 and fixedly connected to the frame assembly 2. The fixing bolt 31 allows the roller 32 to rotate inside the frame assembly 2, while the fixing bolt 31 is fixed to the outside of the frame assembly 2. During cable laying, the traction rope pulls the cable in the laying direction, and the cable slides on the roller 32, reducing the workload of the drone and the traction rope, making the laying work smoother and improving laying efficiency. In a preferred embodiment, the roller 32 is made of insulating epoxy resin. Insulating epoxy resin has relatively low hardness, avoiding damage to the cable. The remaining V-shaped pulley structures are all made of steel to meet the overall structural strength requirements of the entire V-shaped pulley and ensure the supporting effect of the V-shaped pulley on the cable during use.

[0044] Combination Figures 1 to 3 In a preferred embodiment, the base 1 includes a first mounting plate 11, a second mounting plate 12, and a connecting plate 13. The first mounting plate 11 is fixedly connected to the frame assembly 2, and the second mounting plate 12 is connected to the first mounting plate 11 via the connecting plate 13. The second mounting plate 12 is located on the side of the first mounting plate 11 away from the frame assembly 2. The first mounting plate 11 is used to fixably connect the frame assembly 2, and the second mounting plate 12 is used for mounting the V-shaped trolley on a cable laying support, which can be a cable tower, cable post, or other top support for cable laying. The specific location of the connecting plate 13 is not limited; it can be located between the first mounting plate 11 and the second mounting plate 12, fixedly connected to the front of the first mounting plate 11 and the second mounting plate 12, to ensure a reliable connection between the first mounting plate 11 and the second mounting plate 12. In a preferred embodiment, the connecting plate 13 is located on one side of the first mounting plate 11 and the second mounting plate 12, forming an installation space between the first mounting plate 11 and the second mounting plate 12 for mounting the V-shaped trolley. The first mounting plate 11, the connecting plate 13, and the second mounting plate 12 can be connected by welding, screwing, or snap-fitting, or they can be integrally formed to improve the integrity of the base 1.

[0045] The installation method of the second mounting plate 12 during the use of the V-shaped trolley is not limited here. In a preferred embodiment, it is connected by bolts, with mounting bolts 14 provided at the bottom of the base 1. The second mounting plate 12 has through holes 12a, and the mounting bolts 14 are adapted to the through holes 12a. During the installation of the V-shaped trolley, the mounting space of the base 1 is engaged with the cable laying bracket. The mounting bolts 14 extend into the mounting space through the through holes 12a and abut against the bracket. This arrangement facilitates the installation and removal of the V-shaped trolley and ensures its stability during cable laying. Preferably, the through holes 12a have threads adapted to the mounting bolts 14, further facilitating the installation and removal of the mounting bolts 14, saving steps in the installation and removal process, and improving work efficiency.
