[0002] The prior art patent CN218289905 discloses a cable conveyor for ground cable laying, which comprises a base, an upper fixed plate a connected to the top of the base through support columns, a plurality of rotating rollers a connected between the upper fixed plate a and the base, a drive motor and a controller on the top of the upper fixed plate a, and a drive roller connected through the output end of the drive motor. A support plate is slidingly connected to the top of the base, a plurality of rotating rollers b are connected between the support plate and an upper fixed plate b, a fixed block a is provided on the base, a screw rod is threadedly connected to the fixed block a, one end of the screw rod is rotatably connected to the support plate, and the other end is provided with a handle; rotating rollers a and rotating rollers b are both fixedly sleeved with conveying rollers outside. The drive roller is connected with the rotating rollers a through a linkage device (a driving sprocket, a driven sprocket and a chain), the upper fixed plate a and the upper fixed plate b are connected through a limiting device (a fixed block b and an extension rod), and the bottom of the support plate is matched with the sliding groove of the base through a sliding block.

[0003] The handle is rotated to drive the screw rod to rotate, the screw rod drives the support plate to slide along the sliding groove of the base, thereby adjusting the distance between the upper fixed plate a and the upper fixed plate b, so that the distance between the two conveying rollers is adapted to the diameter of the cable to be conveyed, and clamping is realized. The controller starts the drive motor, the drive motor drives the drive roller to rotate, the driving sprocket on the drive roller drives the driven sprockets of the rotating rollers a to rotate synchronously through the chain, and the conveying rollers of the rotating rollers a and the rotating rollers b drive the clamped cable to convey through friction. The extension rod connects the two fixed blocks b to prevent the rotating rollers b from tilting during conveying and to ensure the stability of the clamped state.

DETAILED DESCRIPTION

[0040] The present application will be further described below in combination with the drawings and embodiments.

[0041] It should be noted that the following detailed description is exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0042] It is also important to note that the terms used herein are not intended to limit the particular embodiments of the present application disclosed in this specification. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0043] As shown in Figures 1-12 The embodiment provides a device for laying high-voltage cable using distributed power units, which comprises a fixing frame to be installed on a cable bracket 1, the fixing frame comprises a height adjusting assembly, the height adjusting assembly is detachably connected with a shell, the shell is provided with a conveying roller way for conveying the side of the cable, and the bottom of the shell is further detachably connected with a base, the base is detachably connected with a supporting pulley 2 below the conveying roller way, and the bottom of the base is further detachably connected with an extension rod 3 for auxiliary support.

[0044] The detachable modular connection structure design facilitates device transportation and on-site adjustment.

[0045] In the embodiment, the shell is composed of a left shell 4 and a right shell 5 which are fixedly connected with each other, and the left and right shells are made of high-strength aluminum alloy material.

[0046] In the embodiment, in order to enhance the stability of the device in the laying operation, at least two connecting rods 6 are arranged between the top portions of the left and right shells, the left and right ends of the connecting rods are provided with groove strips 7 extending in a direction perpendicular to the conveying direction of the cable, and the left and right shells are fastened as a whole through the first bolts 8 and the first nuts 9 on the groove strips.

[0047] The top portions of the left and right shells are provided with sliding grooves 10 with a "convex" cross section at positions corresponding to the first bolts, the sliding grooves are perpendicular to the groove strips, and the heads of the first bolts are embedded downward into the sliding grooves, and the first bolts can be adjusted in position in the sliding grooves before the first nuts are locked.

[0048] In the embodiment, the conveying roller way is composed of a left conveying roller 11 and a right conveying roller 12 which are driven to rotate by motors respectively, the left conveying roller has a plurality of left conveying rollers which are detachably installed on the left shell, and the right conveying roller has a plurality of right conveying rollers which are detachably installed on the right shell.

[0049] Both the left and right housings are equipped with detachable battery packs, which are high-performance lithium batteries. Both the left and right housings are equipped with drive motors, reducers and transmission structures. Multiple circular holes are provided on the left and right housings along the length direction (the direction of cable delivery). The conveying rollers are rotated and installed in the circular holes. The rotation output of the drive motor is transmitted to the transmission structure through the reducer, and the transmission structure drives the conveying rollers to rotate.

[0050] The transmission structure includes a conveyor belt and a gear set. The gear set meshes with the conveyor belt. One end of the conveyor roller is equipped with a spline 13, and the gears in the gear set are equipped with keyways. The spline and keyways engage to transmit motion. A spring seat is installed inside the housing. When installing the conveyor roller, the unsplined end of the conveyor roller is inserted into the round hole. The conveyor roller presses downward against the spring seat. After pressing a certain distance, the splined end of the conveyor roller is aligned with the upper round hole, and the downward pressing force is released. The conveyor roller is lifted by the spring seat, so that the spline engages with the keyway of the gear in the upper round hole, completing the installation of the conveyor roller. The conveyor roller is available in various diameter specifications, mainly differing in the diameter of the contact part 14 that contacts the cable. The outer surface of the contact part is equipped with anti-slip textures to prevent slippage during cable conveying.

[0051] The above design realizes a distributed power unit, which uses two symmetrical high-strength aluminum alloy shells to house a removable high-performance lithium battery, drive motor, reducer and transmission structure, achieving independent power output and eliminating dependence on external power.

[0052] In this embodiment of the invention, the base consists of a left base 15 detachably connected to the bottom of the left housing and a right base 16 detachably connected to the bottom of the right housing, and the support pulley is detachably installed between the left and right bases.

[0053] In this embodiment of the invention, the bottom of the left and right shells is fixedly provided with dovetail protrusions 17, and the top of the left and right bases is provided with dovetail grooves 18. The dovetail protrusions and dovetail grooves are slidably embedded in each other to realize the detachable connection between the left and right shells and the corresponding left and right bases.

[0054] The length direction of both the dovetail boss and the dovetail groove is parallel to the cable conveying direction.

[0055] In this embodiment of the invention, the bottom surfaces of the left and right bases are provided with internal threaded holes, and the top end of the telescopic rod has external threads to facilitate screwing and installation with the internal threaded holes during use.

[0056] After adjusting the height of the housing and base, connect the telescopic rod to the base and adjust the length of the telescopic rod so that the bottom of the telescopic rod contacts the ground to enhance the stability of the device.

[0057] In this embodiment of the invention, the support pulley has multiple sets, each including a support plate 19. A first gear set 20 and a second gear set 21 are rotatably connected on the support plate, and a conveyor belt 22 is wound around the outer periphery of the first and second gear sets. The support pulley can be either unpowered or powered. In the case of a powered version, the first gear set or the second gear set is the driving wheel that is driven to rotate by a motor.

[0058] The outer layer of the conveyor belt is provided with an anti-slip layer, which serves both as support during the laying process and as a way to prevent the cable from slipping during the transmission of the cable.

[0059] The left and right bases are each provided with a first fixing hole 23 on one side and a first fixing block 24 fixedly provided on the other opposite side. The support plate is provided with a second fixing block 25 on one side and a second fixing hole 26 on the other opposite side.

[0060] The left base is connected to the left side of the support plate by a first fixing hole and a second fixing block; the right base is connected to the right side of the support plate by a second fixing hole and a first fixing block; and when multiple sets of support pulleys are assembled in series, two adjacent support pulleys are also connected by a second fixing block and a second fixing hole.

[0061] In this embodiment of the invention, both the left and right ends of the housing are connected to a height adjustment assembly of a fixing frame.

[0062] In this embodiment of the invention, the fixing frame further includes a fixing base 27, the height adjustment component includes a second bolt 28 vertically locked on the fixing base, and a connecting block 29 with a mounting through hole is fixedly provided on the left and right shells and their corresponding bases. After the second bolt passes through the mounting through hole of the connecting block, a second nut 30 is screwed and locked on the second bolt above and below the connecting block. Each of the fixed bases is provided with a limiting groove 31 to facilitate the insertion of one of the cable drag rods 32 fixedly suspended on the cable tray. The cable drag rod is made of angle steel and consists of multiple rods; the shape of the limiting groove is adapted to the cable drag rod. The connection between the fixed base and the cable tray is achieved through the cooperation of the limiting groove and the cable drag rod, thereby realizing the connection between the entire device and the cable tray in this application.

[0063] By adjusting the position of the second nut on the second bolt, the height of the housing and base can be adjusted so that the cable on the support pulley is just above the cable support rod of the cable tray during the laying operation.

[0064] In another embodiment of the present invention, another structure of the fixing frame is to further include an electro-permanent magnet chuck (instantaneous current control switch, which does not demagnetize after power failure) for magnetically attaching to the cable drag rod of the cable tray. The height adjustment component adopts a horizontal and vertical moving slide 33. The horizontal end of the moving slide is fixedly connected to the left and right shells and their corresponding bases, and the vertical end of the moving slide is fixedly connected to the electro-permanent magnet chuck.

[0065] The movable slide includes a transverse guide rail 34 fixedly connected to the left and right housings and their corresponding bases. A vertical guide rail 36 is fixedly connected to the transverse slider 35 of the transverse guide rail, and the electro-permanent magnet chuck is fixedly connected to the vertical slider 37 of the vertical guide rail. Furthermore, the transverse sliding adjustment of the transverse slider uses a transverse ball screw pair driven by a motor, and the vertical sliding adjustment of the vertical slider uses a vertical ball screw pair driven by a motor; the ball screw pair is existing technology.

[0066] The electro-permanent magnet chuck allows for magnetic connection between the mounting bracket and the cable tray. By controlling the magnetism of the electro-permanent magnet chuck with pulsed current, quick connection and disconnection between the mounting bracket and the cable tray can be achieved. The movable slide table can adjust the horizontal and vertical positions of the base and housing, ensuring that the cable on the support pulley is positioned directly above the cable support rod of the cable tray during laying operations.

[0067] When using an electro-permanent magnet chuck for connection, no telescopic rod is required for auxiliary support.

[0068] A method for laying high-voltage cables using a distributed power unit includes the following steps: S1. Disassembly and Transportation of the Device: The device is disassembled into separate modules, including left and right shells, left and right bases, support pulleys, fixed frames, and left and right conveyor rollers, and transported to the designated location at the construction site. S2, Basic Assembly: S21. First, install the fixing bracket in the preset position of the cable tray, install the left and right bases on the corresponding fixing brackets, and then install the left and right shells on the left and right bases respectively. S22. Select the corresponding specifications of left and right conveyor rollers according to the cable diameter, and install the left and right conveyor rollers onto the left and right housings respectively. That is, insert the spline-free end of the conveyor roller into the round hole of the housing, squeeze the spring seat and release it in alignment with the upper round hole, so that the spline and gear keyway cooperate to complete the installation. S23. Connect the support pulleys in series according to the laying requirements. The left base and the left side of the support plate are interlocked with each other, and the right base and the right side of the support plate are interlocked with each other. If multiple sets of support pulleys need to be assembled in series, the two adjacent support pulleys are also interlocked with each other. S3. Mounting bracket installation and height adjustment: S31. Adjust the height of the left and right housings and the left and right bases using the height adjustment components so that the cable on the support pulley is just above the cable support rod of the cable tray, ensuring that the laying height meets the requirements. S4, Enhanced stability: S41. Tighten the first bolt and the first nut on the connecting rod to fix the two symmetrical left and right shells through the connecting rod and enhance the connection strength; S42. Based on the flatness of the construction site, connect and install the telescopic rod to the left and right bases, adjust the length of the telescopic rod so that its bottom contacts the ground, and ensure that the device does not shake. S5. Cable laying: S51. Place the high-voltage cable 38 on the left and right conveyor rollers and the support pulley, and check the fit between the cable and the left and right conveyor rollers. S52. Start the drive motor, which drives the left and right conveyor rollers to rotate through the reducer and transmission structure. The friction of the anti-slip texture of the left and right conveyor rollers drives the cable conveying. The cable path is manually adjusted to complete the laying operation. S6. Disassembly and Storage of Equipment: After installation, disassemble the equipment in reverse order of assembly, clean the impurities on the surface of the left and right conveyor rollers, and sort and store each separate module.

[0069] In this embodiment of the invention, in step S21, the fixing frame can be connected to the cable support rod through the limiting groove, or the fixing frame can be magnetically attracted to the cable bracket through the electro-permanent magnet chuck.

[0070] In this embodiment of the invention, tilt sensors (Bluetooth six-axis horizontal tilt sensors, model: BWT61CL) are also installed in the middle of the left and right bases. Based on MEMS accelerometers and gyroscopes, these sensors calculate the tilt angle by detecting the gravitational acceleration component, output digital signals, monitor the cable laying angle, and assist in adjusting the telescopic rod and fixing frame to ensure that the cable laying angle meets design requirements. Cable speed sensors (Hall sensor YS40AF) are installed on the outer side of the left and right housings near the conveying rollers. These sensors detect the number of rotations and frequency of the conveying rollers through infrared beams, calculate the cable conveying speed based on the roller diameter, and provide real-time feedback on the cable laying speed to avoid cable pulling or accumulation caused by inconsistent speeds during multi-segment laying. Temperature sensors (Beijing Kunlun Coast wireless temperature sensor JWB-CW2000) based on PT100 are installed near the battery pack inside the left and right housings. The resistance value of platinum resistance thermometers changes with temperature, converting the temperature signal into a standard electrical signal to monitor the operating temperature of the lithium battery pack and prevent overheating of the battery from causing safety hazards. The motor housing is equipped with a vibration sensor (GZW25-120 industrial vibration condition monitoring temperature and vibration integrated piezoelectric vibration sensor). Based on the piezoelectric ceramic sensing element, the mechanical quantity of motor vibration is converted into an electrical signal to reflect the motor's operating status, monitor the motor's operating stability in real time, and promptly detect motor faults or abnormal transmission structures.

[0071] The embodiments of the present invention have the following beneficial effects: 1. Significantly improved ease of movement and transfer: Adopting a modular and detachable design (both the shell-base and the support pulley-base are quick-assembly and disassembly structures), the individual components are small in size and light in weight after disassembly, and can be transferred and repositioned on site without the need for external tools.

[0072] 2. Angle and height adjustment capability to adapt to complex terrain: With the height adjustment function of the fixed frame and the auxiliary support of the telescopic pole, it can adapt to the construction site with slopes and uneven terrain, and realize non-horizontal cable laying.

[0073] 3. Optimized cable sheath protection: The conveyor rollers feature an anti-slip textured design to avoid relying solely on clamping force for conveying, thus reducing the risk of slippage; at the same time, the detachable structure facilitates the replacement of worn conveyor rollers, preventing cable sheath damage caused by improper clamping force adjustment.

[0074] 4. Enhanced equipment adaptability and expandability: It can be equipped with conveyor rollers of various diameters, and can adapt to cables of different diameters by assembling multiple sets of support pulleys in series and changing rollers, without having to replace the entire set of equipment.

[0075] 5. Balancing construction efficiency and stability: Modular design shortens on-site assembly time, distributed power units reduce power transmission losses, and stability-enhancing components (linkage rods, telescopic rods) ensure that the equipment does not shift or shake during laying, improving laying quality and efficiency.

[0076] 6. This device has the advantages of small size and light weight. It can be directly connected to the cable tray. The device is laid along the laying line, and the installation interval is shortened to 5-10 meters, which can improve the continuity and stability of cable transportation.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
