Description

Technical Field

[0001] This invention relates to the field of cable laying construction, and in particular to a device and method for laying large-section cables in conjunction with power storage projects. Background Technology

[0002] Traditional large-section cable laying methods, lacking a systematic equipment coordination solution and limited by the "large weight and high rigidity" characteristics of large-section cables, generally suffer from the following key problems, making it difficult to meet the requirements of efficient and low-damage construction: Insufficient or overloaded traction can easily damage the cable structure; high frictional resistance leads to severe wear on the cable sheath; low directional control accuracy makes turning operations difficult; and high reliance on manual labor results in an imbalance between construction costs and efficiency.

[0003] To address the shortcomings of traditional laying methods, some improvement solutions have emerged in existing technologies. However, due to imperfect design, these solutions have not fundamentally solved the problems. Specific limitations are as follows: First, traction force enhancement solutions: disordered equipment spacing and uneven power output. Some solutions attempt to increase traction force by increasing the number of traction devices (such as adding multiple traction machines along the path), but the equipment spacing is not rationally planned according to the cable's weight and path length. This results in asynchronous and uneven power output from each traction device—excessive power in some sections (easily causing overload and cable damage), and insufficient power in others (still leading to laying stagnation), making stable laying impossible. Second, friction reduction solutions: excessively large support structure spacing and limited drag reduction effect. Other solutions attempt to reduce friction by setting simple support structures (such as widely spaced metal rollers), but the spacing between support structures generally exceeds 10 meters. The cable still sags due to its own weight between adjacent support structures, contacting the ground or debris along the path and generating friction. The actual drag reduction effect is only less than 20%, far from meeting the low-friction laying requirements of large-section cables, and the problem of cable sheath wear has not been effectively alleviated.

[0004] This invention utilizes the coordinated operation of a traction machine, a cable conveyor, and a cable trolley to form a highly efficient and low-damage large-section cable laying system. Summary of the Invention

[0005] The purpose of this invention is to address the significant shortcomings of existing technologies in terms of dynamic balance, friction control, directional accuracy, and cost efficiency in laying large-section cables.

[0006] The technical solution of the present invention: A large-section cable co-laying construction device suitable for electric field energy storage projects, comprising a cable conveyor body, both ends of which are fixedly connected to guide frames, and an auxiliary component provided on one side of the cable conveyor body. The auxiliary component includes a support fixedly connected to one side of the cable conveyor body, and a plurality of positioning holes are provided on one side of the support. The plurality of positioning holes are arranged in a circumferential array. A side shaft is slidably connected to the inner side of the support, and a shaft end plate is fixedly connected to one end of the side shaft. A connecting column is slidably connected to the inner side of the shaft end plate.

[0007] Optionally, one end of the connecting column is fixedly connected to a connecting frame, and a fixed bushing is sleeved on the inner side of the connecting frame. The fixed bushing is threadedly connected to the shaft end plate.

[0008] Optionally, a positioning ring is fixedly connected to one end of the fixed bushing away from the connecting frame, and a plurality of positioning beads are fixedly connected to one side of the positioning ring. The positioning beads are hemispherical, and the inner contour of the positioning hole matches the contour of the positioning beads.

[0009] Optionally, a drive shaft is slidably connected inside the guide frame, and a handle is fixedly connected to the outside of the drive shaft.

[0010] Optionally, the fixed bushing is slidably connected to the outside of the drive shaft.

[0011] Optionally, a limiting component is slidably connected inside the drive shaft, and a spring is fixedly connected to the bottom of the limiting component, the spring being fixedly connected inside the drive shaft.

[0012] Optionally, one end of the side shaft is fixedly connected to an auxiliary support rod, and one side of the auxiliary support rod is fixedly connected to a limiting pin, which is inserted into the top of the support.

[0013] Optionally, an extension rod is slidably connected to the inner side of the auxiliary support rod, one end of the extension rod is fixedly connected to a support leg, a bolt assembly is inserted into the inside of the auxiliary support rod, and multiple through holes are opened on one side of the extension rod, with the bolt assembly inserted into the inner side of the through holes.

[0014] Optionally, a connecting sleeve rod is fixedly connected to one side of the support leg, a connecting inner column is slidably connected to the inner side of the connecting sleeve rod, and a handle is fixedly connected to the outer side of the connecting inner column.

[0015] This invention also provides a method for laying large-section cables in conjunction with power storage projects, comprising the following steps: Route survey and equipment installation: First, survey the cable laying route to determine the route length and slope; then, lay out the equipment according to the design, install traction machines at the starting end and key turning positions, install cable conveyor bodies at intervals along the route, install cable trolleys between adjacent conveyors, and finally adjust the height of all equipment to ensure a smooth laying route. Cable laying: One end of the large cross-section cable to be laid is passed sequentially through the guide wheel group of the traction machine, the clamping gap between the drive wheel and the driven wheel of each cable conveyor body, and the arc-shaped groove of each cable trolley; Tractor Start-up and Direction Alignment: Start the hydraulic system of the tractor and adjust the angle of the guide wheel set through the direction adjustment mechanism to make the wheel set axis consistent with the starting section of the laying path and determine the initial laying direction; Conveyor synchronous start-up: The power components of all cable conveyors are started synchronously through the frequency converter control cabinet. The speed of the frequency converter motor is set, and the drive wheel rotates to move the cable along the laying direction. At the same time, the cable drives the trolley pulley to rotate, reducing frictional resistance. Real-time monitoring and completion of laying: During the laying process, the direction is monitored by the traction machine angle sensor and the power output is monitored by the conveyor current sensor. At the same time, construction personnel are arranged to inspect along the path until the end of the cable reaches the end of the path, then all equipment is shut down and the laying is completed.

[0016] In summary, this application includes at least one of the following beneficial technical effects: This invention overcomes the problem of poor directional control of traditional single traction equipment. By combining a traction machine with an angle sensor, it can not only accurately control the laying direction of straight sections, but also adapt to the requirements of critical turning positions, reducing the risk of construction deviation. Furthermore, unlike the traditional solution of "increasing the number of traction devices but without reasonable spacing", the spaced cable conveyor body, in conjunction with the variable frequency motor, can dynamically adjust the power according to the cable laying requirements. This avoids laying stagnation caused by insufficient traction force and prevents overload damage to the cable. It is suitable for the stable laying of cables with different cross-sections. At the same time, the cable conveyor body and auxiliary components can cope with various situations in the actual conveying process and meet the various actual needs of cable conveying. Furthermore, by using nylon trolleys with arc-shaped grooves, frictional resistance and outer sheath wear are significantly reduced. Compared with traditional structures without trolleys or with large spacing, the cable wear rate is significantly reduced and the service life is extended. At the same time, it avoids the safety hazards of direct friction between cables and the ground and supports in traditional laying. Furthermore, by coordinating the traction machine, cable conveyor, and pulley, the efficiency is improved compared to traditional laying methods; and the reduction of manual intervention reduces both labor costs and safety risks caused by improper human operation.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0021] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Example 1: As Figures 1-7 As shown, a large-section cable collaborative laying construction device suitable for electric field energy storage projects includes a cable conveyor body 1. Guide frames 2 are fixedly connected to both ends of the cable conveyor body 1. An auxiliary component is provided on one side of the cable conveyor body 1. The auxiliary component includes a support 3 fixedly connected to one side of the cable conveyor body 1. Multiple positioning holes 4 are opened on one side of the support 3. The multiple positioning holes 4 are distributed in a circumferential array. A side shaft rod 5 is slidably connected to the inner side of the support 3. A shaft end plate 6 is fixedly connected to one end of the side shaft rod 5.

[0025] A connecting post 7 is slidably connected to the inner side of the shaft end plate 6. A connecting frame 8 is fixedly connected to one end of the connecting post 7. A fixed bushing 9 is sleeved on the inner side of the connecting frame 8. The fixed bushing 9 is threadedly connected to the shaft end plate 6. A positioning ring 23 is fixedly connected to the end of the fixed bushing 9 away from the connecting frame 8. A plurality of positioning beads 24 are fixedly connected to one side of the positioning ring 23. The positioning beads 24 are hemispherical. The inner contour of the positioning hole 4 matches the contour of the positioning beads 24.

[0026] The fixed bushing 9 can rotate inside the connecting frame 8. The connecting frame 8 can only slide horizontally through the fixed bushing 9. The fixed bushing 9 is threadedly connected to the shaft end plate 6, so that when the fixed bushing 9 is rotated, the connecting frame 8 can be moved closer to or away from the shaft end plate 6.

[0027] The guide frame 2 has a drive shaft 10 slidably connected inside, and a handle 11 is fixedly connected to the outside of the drive shaft 10. A fixed bushing 9 is slidably connected to the outside of the drive shaft 10. A limit member 12 is slidably connected inside the drive shaft 10. The limit member 12 is set in a right-angled triangular outline and can be inserted into the inside of the fixed bushing 9. A spring piece 13 is fixedly connected to the bottom of the limit member 12. The spring piece 13 is an elastic structure and is fixedly connected inside the drive shaft 10.

[0028] An auxiliary support rod 14 is fixedly connected to one end of the side shaft rod 5. A limiting pin 15 is fixedly connected to one side of the auxiliary support rod 14. The limiting pin 15 is inserted into the top of the support 3. The limiting pin 15 can fix the position of the auxiliary support rod 14 and keep the auxiliary support rod 14 in a vertical state, so as to facilitate the storage of the auxiliary support rod 14. An extension rod 16 is slidably connected to the inner side of the auxiliary support rod 14. A support foot 17 is fixedly connected to one end of the extension rod 16. A bolt assembly 18 is inserted into the inside of the auxiliary support rod 14. The bolt assembly 18 consists of bolts and nuts. Multiple through holes 19 are opened on one side of the extension rod 16. The bolt assembly 18 is inserted into the inside of the through holes 19. A connecting sleeve rod 20 is fixedly connected to one side of the support foot 17. A connecting inner column 21 is slidably connected to the inner side of the connecting sleeve rod 20. A handle 22 is fixedly connected to the outer side of the connecting inner column 21. The handle 22 has multiple arc-shaped grooves to facilitate hand gripping.

[0029] In this embodiment, the cable conveyor body 1 can transport the cable. During cable transport, the auxiliary support rods 14 on both sides of the box are pulled apart, causing the auxiliary support rods 14 to move away from each other. This allows the positioning ring sleeve 23 to gradually approach the support 3. When one end of the fixed bushing 9 coincides with the limiting member 12, the limiting member 12 loses its limiting position. The spring piece 13 is elastically stretched, causing the limiting member 12 to move outward and insert into the fixed bushing 9. At this time, the limiting insert 15 disengages from the top of the support 3, allowing the auxiliary support rod 14 to flip. Flipping the auxiliary support rod 14 causes the support leg 17 to contact the ground. Rotating the handle 11 causes the drive shaft 10 to rotate, thereby driving the fixed bushing 3 through the limiting member 12. The bushing 9 rotates, which in turn drives the connecting frame 8 to move towards the shaft end plate 6 through the fixed bushing 9. This causes the positioning ring 23 to drive the positioning bead 24 to insert into the inside of the positioning hole 4. The positioning bead 24 and the positioning hole 4 are mutually limited by the insertion, so that the side shaft rod 5 and the positioning ring 23 cannot rotate, keeping the auxiliary support rod 14 horizontal. This allows the support feet 17 at the four corners to contact the ground, which can increase the contact area between the cable conveyor body 1 and the ground, improve the overall stability of the cable conveyor body 1, and avoid the impact of poor terrain on the normal transport of cables due to less friction between the cable conveyor body 1 and the ground. At the same time, when transporting large cross-section cables, the increased stability of the cable conveyor body 1 can help transport the cables.

[0030] By removing the bolt assembly 18 and pulling the through hole 19 out from the inside of the auxiliary support rod 14, the overall length of the auxiliary support rod 14 and the support leg 17 can be extended, thereby further increasing the contact area between the cable conveyor body 1 and the ground. Simultaneously, the auxiliary support rod 14 at one end of the cable conveyor body 1 is flipped to an inclined state and fixed, thus placing the cable conveyor body 1 in an inclined position. Since large-section cables are difficult to bend, and when the cable lead-out end is high, the cable conveyor body 1, placed horizontally at a low position, cannot properly convey the cable. Therefore, by tilting the cable conveyor body 1, the cable conveyor body 1 is placed at a higher position. One end of the device can be close to the cable, allowing the cable to be transported from a high position downwards without bending it. Simultaneously, by flipping the auxiliary support rods 14 at both ends of the cable conveyor body 1 downwards, the overall height of the cable conveyor body 1 can be increased. The height of the cable conveyor body 1 can be adjusted according to the flipping angle of the auxiliary support rods 14. Therefore, when the height of the cable conveyor body 1 is insufficient, the auxiliary components can be adjusted to bring the cable conveyor body 1 to the required height for cable transport. This avoids various unfavorable situations when transporting large-section cables.

[0031] This invention also provides a method for laying large-section cables in conjunction with power storage projects, comprising the following steps: Route survey and equipment installation: First, survey the cable laying route to determine the route length and slope; then, lay out the equipment according to the design, install traction machines at the starting end and key turning positions, install cable conveyor bodies 1 at intervals along the route, install cable trolleys between adjacent cable conveyor bodies 1, and finally adjust the height of all equipment to ensure a smooth laying route. Cable laying: One end of the large cross-section cable to be laid is sequentially passed through the guide wheel group of the traction machine, the clamping gap between the drive wheel and the driven wheel of each cable conveyor body 1, and the arc-shaped groove of each cable trolley. Tractor Start-up and Direction Alignment: Start the hydraulic system of the tractor and adjust the angle of the guide wheel set through the direction adjustment mechanism to make the wheel set axis consistent with the starting section of the laying path and determine the initial laying direction; Cable conveyor body 1 starts synchronously: The power components of all cable conveyor bodies 1 are started synchronously through the frequency converter control cabinet, the speed of the frequency converter motor is set, the drive wheel rotates and drives the cable to move along the laying direction; at the same time, the cable drives the trolley pulley to rotate, reducing frictional resistance; Real-time monitoring and completion of laying: During the laying process, the direction is monitored by the angle sensor of the traction machine and the power output is monitored by the current sensor of the cable conveyor body 1. At the same time, construction personnel are arranged to inspect along the path until the end of the cable reaches the end of the path, then all equipment is shut down and the laying is completed.

[0032] In this embodiment, preliminary route surveying and equipment deployment preparation: First, a comprehensive survey of the cable laying route is conducted to accurately determine the total length of the route. At the same time, the slope of the route is checked to ensure that the final laying route is horizontal or gently inclined, and the inclination angle is strictly controlled to be no more than 5°, so as to avoid the cable slipping or the traction force increasing suddenly due to excessive slope, which would affect the laying stability.

[0033] Precise installation and commissioning of core equipment: Based on the route determined by the survey, the three core pieces of equipment were deployed according to the following standards and commissioned: Cable Traction Machine Installation: Install one cable traction machine at the beginning of the cable laying path (or at a critical turning point in the path), ensuring that the machine body is firmly fixed and free from shaking; at the same time, check the guide wheel assembly, direction adjustment mechanism and angle sensor of the cable traction machine to ensure that all components move smoothly and the sensor signals are normal. Cable conveyor body 1 installation: Install one cable conveyor body 1 every 50 meters along the laying path (at least 2 are required, the specific number is adapted according to the path length). During installation, ensure that the cable conveyor body 1 is horizontal and the axes of the drive wheel and the driven wheel are parallel; debug the power components (including the variable frequency motor), current sensor and variable frequency control cabinet of the cable conveyor body 1 to ensure that the power output and signal monitoring functions are normal. Cable trolley installation: Install one cable trolley every 5 meters along the laying path between two adjacent cable conveyor bodies 1 (the number is calculated based on the spacing of the cable conveyor bodies 1 and the total length of the path), ensuring that the trolley base is fixed and stable and the bracket is not deformed; check the flexibility of the nylon pulley of the trolley to confirm that the arc groove on the outer circumference of the pulley is compatible with the diameter of the large cross-section cable to be laid. Uniform equipment height adjustment: After all equipment is installed, uniformly adjust the height of the traction machine, cable conveyor body 1, and cable trolley to ensure that the support points of the three are on the same horizontal line (or conform to the gentle slope of the path), so as to provide a smooth transmission channel for cable laying.

[0034] Cables are laid out in an orderly manner: Use one end of the large-section cable to be laid as the "traction end" and thread it through each piece of equipment in the following order, ensuring that the cable is compatible with the equipment and undamaged: First, pass the cable pulling end through the guide wheel assembly of the traction machine, and adjust the gap between the two guide wheels to make it perfectly match the cable diameter. This ensures that the cable can pass through smoothly and avoids the cable from deviating due to excessive gap. Next, the cable traction end is passed through the clamping gap between the drive wheel and the driven wheel of each cable conveyor body 1 in sequence. The gap size is adjusted to ensure that the cable is stably clamped and that the cable sheath or internal structure is not damaged due to squeezing. Finally, place the cable pulling end and subsequent cable segments into the arc-shaped grooves of each cable trolley, ensuring that the cable is completely fitted into the grooves and that the pulleys can rotate flexibly as the cable moves.

[0035] Equipment coordinated start-up and laying control: Traction machine start-up and direction calibration: Start the hydraulic system of the traction machine and slowly adjust the angle of the guide wheel group through the direction adjustment mechanism to make the axis of the guide wheel group completely consistent with the starting section of the laying path, and determine the initial laying direction of the cable; at this time, the angle sensor of the traction machine monitors the angle of the guide wheel group in real time to ensure that the direction deviation does not exceed ±1°; Synchronous start of cable conveyor body 1: A synchronous start command is sent to all cable conveyor bodies 1 via the frequency converter control cabinet to start the power components; the speed of the frequency converter motor is set so that the linear speed of the drive wheel of the cable conveyor body 1 is stabilized at 1m / min (the speed can be finely adjusted by the frequency converter control cabinet according to the actual resistance of cable laying). When the drive wheel rotates, it drives the cable to move smoothly along the laying direction; at the same time, the cable will drive the nylon pulleys of each cable trolley to rotate synchronously during the movement, converting the sliding friction between the cable and the trolley into rolling friction.

[0036] Real-time monitoring and inspection of the laying process: Throughout the cable laying process, safety and stability must be ensured through a dual approach of "equipment monitoring + manual inspection": Real-time monitoring of equipment parameters: The angle of the guide wheel group is continuously monitored by the angle sensor of the traction machine. If the directional deviation exceeds ±1°, it is corrected in time by the directional adjustment mechanism. The output current of the power component is monitored by the current sensor of the cable conveyor body 1. When the current exceeds the rated value by 10%, the system automatically reduces the motor speed to avoid overload damage to the cable or the cable conveyor body 1. Manual inspection along the entire laying path: Arrange construction personnel to inspect the entire laying path, focusing on two aspects: First, whether the cable sheath is worn or scratched (especially at the contact points between the equipment and the cable); Second, the operating status of the traction machine, cable conveyor body 1, and cable trolley (such as whether the machine body is shaking, whether the pulley is stuck, and whether the motor makes abnormal noises). If any problems are found, stop the machine immediately for handling.

[0037] Laying completion and equipment shutdown: When the end of the cable (non-traction end) reaches the end of the laying path, the motor speed of the cable conveyor body 1 is gradually reduced through the frequency converter control cabinet until the cable conveyor body 1 stops running; then the hydraulic system of the traction machine is turned off and the directional control is stopped; finally, the overall position of the cable laying is checked to see if it meets the design requirements. After confirming that there are no abnormalities, the laying operation of this large cross-section cable is completed.

[0038] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
