Description

Technical Field

[0001] This application relates to the field of cable equipment, and in particular to a retractable cable laying device and cable laying method. Background Technology

[0002] Currently, cable laying requires two hoisting operations for the cable reel, relying entirely on cranes. This is not only time-consuming and labor-intensive in terms of manpower, but also poses significant safety hazards. Furthermore, hoisting operations have stringent environmental requirements, needing to be carried out in open areas. Narrow streets and old urban areas often suffer from obstacles such as buildings, utility poles, and trees, preventing the proper loading, unloading, and deployment of cable reels. This traditional operating method is not only inefficient but also faces significant limitations in complex terrain and congested areas due to its stringent site requirements, severely restricting the convenience and safety of cable laying projects. Summary of the Invention

[0003] This application aims to provide a retractable cable laying device and cable laying method that can reduce dependence on the construction environment and construction auxiliary equipment.

[0005] The main crossbeam frame includes two parallel crossbeams and a traveling mechanism disposed under each of the crossbeams;

[0006] A retractable front beam is connected between the front ends of the two crossbeams;

[0007] A retractable rear beam is connected between the rear ends of the two crossbeams; at least one of the retractable rear beam and the retractable front beam is used to actively adjust the spacing between the two crossbeams; the retractable rear beam is configured as an openable and closable structure.

[0008] Two support mechanisms are respectively installed on the two crossbeams. Each support mechanism is equipped with a lifting structure, and the lifting structure can move in a direction perpendicular to the main crossbeam frame. The two lifting structures are arranged opposite to each other and are used together to rotate the support cable reel.

[0009] A rotation drive device is mounted on the retractable front beam, the retractable rear beam, or the main crossbeam frame;

[0011] When the retractable rear beam is open, the main crossbeam frame and the retractable front beam form an open structure.

[0012] A cable laying method according to a second aspect of this application is used to control a retractable cable laying device as described in the first aspect embodiment, the cable laying method comprising:

[0013] The retractable rear beam is controlled to open so that the main crossbeam frame and the retractable front beam form an opening structure, wherein the distance between the two crossbeams in the opening structure is greater than the width of the cable reel;

[0014] Control the walking mechanism to move so that the cable reel is located within the opening structure, and the center structure of the cable reel is parallel to the line connecting the two lifting structures and coincides in the direction perpendicular to the main beam frame;

[0044] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0045] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0046] See Figures 1 to 7 As shown, one embodiment of this application provides a retractable cable laying device, which includes:

[0047] The main crossbeam frame includes two parallel crossbeams 110 and a traveling mechanism 120 disposed under each crossbeam 110;

[0048] The retractable front beam 200 is connected between the front ends of the two crossbeams 110;

[0049] A retractable rear beam 300 is connected between the rear ends of two crossbeams 110; at least one of the retractable rear beam 300 and the retractable front beam 200 is used to actively adjust the spacing between the two crossbeams 110; the retractable rear beam 300 is configured as an openable and closable structure.

[0050] Two support mechanisms 400 are respectively set on two crossbeams 110. Each support mechanism 400 is equipped with a lifting structure 410, and the lifting structure 410 can move in a direction perpendicular to the main crossbeam frame. The two lifting structures 410 are arranged opposite to each other and are used together to rotate the support cable reel 700.

[0051] A rotation drive device 500 is mounted on the telescopic front beam 200, the telescopic rear beam 300, or the main crossbeam frame.

[0052] The control system 600 is used to control the opening or closing of the telescopic rear beam 300, control the telescopic rear beam 300 and / or the telescopic front beam 200 to extend and retract to adjust the distance between the two crossbeams 110, control the height of the lifting structure 410 in the two support mechanisms 400, and control the rotation drive device 500 to drive the cable reel 700 supported by the two lifting structures 410 to rotate.

[0053] When the retractable rear beam 300 is open, the main crossbeam frame and the retractable front beam 200 form an open structure.

[0054] In this embodiment, the retractable cable laying device can be quickly transported using a tractor unit 800, allowing for direct use without on-site assembly, hoisting, or debugging, effectively improving cable laying efficiency. Simultaneously, the retractable front beam 200 and retractable tail beam can accommodate cable reels 700 of different specifications, facilitating operation. Combined with a liftable support mechanism 400, the cable reels 700 can be actively loaded and unloaded, eliminating reliance on cranes or other auxiliary equipment. Furthermore, the retractable cable laying device in this application is simple to operate, has low requirements for the construction environment, roads, and space, and occupies little space. It is particularly suitable for scenarios where large hoisting equipment cannot access, such as narrow streets, buildings, or tree obstructions. It can be put into use immediately upon arrival at the site, significantly improving construction convenience and emergency response capabilities.

[0055] The aforementioned main crossbeam frame includes two parallel crossbeams 110. Each crossbeam 110 has a set of wheels at its bottom as a walking mechanism 120, and each set of wheels can have at least two wheels.

[0056] A groove structure can be provided in the middle of the aforementioned crossbeam 110 to better assist the support mechanism 400 in its installation.

[0057] The aforementioned retractable front beam 200 and retractable rear beam 300 can extend and retract in the direction in which the two crossbeams 110 approach or move away from each other.

[0058] It should be noted that at least one of the retractable front beam 200 and retractable rear beam 300 has an active retraction capability to provide the power to bring the two crossbeams 110 closer to or further apart.

[0059] The aforementioned retractable rear beam 300 can also be opened and closed so that when it is necessary to clamp the cable reel 700 placed on the ground, the retractable rear beam 300 can be opened to form an opening structure, and the main crossbeam frame can be moved by the traction head 800 so that the cable reel 700 can be placed in the opening structure.

[0060] The aforementioned support mechanism 400 is arranged perpendicular to the crossbeam 110 so that the lifting structure 410 installed inside the support mechanism 400 can better achieve movement in the direction perpendicular to the crossbeam 110.

[0061] Understandably, the lifting structures 410 on the two support mechanisms 400 can be raised and lowered synchronously to achieve alignment with the central structure of the cable reel 700.

[0062] The central structure of the cable reel 700 can be brought into contact with the lifting structure 410 so that the cable reel 700 can be raised and lowered synchronously when the two lifting structures 410 are raised and lowered.

[0063] In actual operation, the tractor head 800 moves the main crossbeam frame, placing the cable reel 700 within the open structure. The central structure of the cable reel 700 is parallel to the line connecting the two lifting structures 410, and they coincide in the direction perpendicular to the main crossbeam frame. Then, the height of the lifting structure 410 can be adjusted to align the lifting structure 410 with the central structure of the cable reel 700. After alignment, the two parallel crossbeams 110 are driven to move towards each other, so that the central structure of the cable reel 700 can come into contact with the lifting structure 410, ultimately clamping the cable reel 700 and enabling lifting and lowering control of the cable reel 700.

[0064] The aforementioned rotation drive device 500 can be installed on any crossbeam 110 or on the telescopic front beam 200 to drive the cable reel 700 to rotate.

[0065] The aforementioned rotary drive device 500 can use various drive forms. For example, a friction wheel can be used as the drive mechanism. By setting a friction structure on the cable reel 700 that cooperates with the friction wheel, the cable reel 700 can be driven. Alternatively, a gear can be used as the drive mechanism. By setting a meshing structure on the cable reel 700 that cooperates with the gear, the cable reel 700 can be driven. Any other mechanism that can achieve the drive can also be used. There are various specific drive forms, and in actual engineering, they can be selected according to actual needs.

[0066] The aforementioned friction structure can be obtained by directly setting a material or structure that increases friction on the rim of the cable reel 700.

[0067] The aforementioned control system 600 includes an electrical control unit and a drive system connected to the electrical control unit. The drive system provides a power source for driving the telescopic front beam 200 and / or the telescopic rear beam 300, a power source for the rotation drive device 500, a power source for the lifting structure 410, a power source for the opening and closing of the telescopic rear beam 300, and a power source for the operation of the outrigger mechanism 900.

[0068] The aforementioned drive system can be either a hydraulic drive system or an electric drive system, or a combination of both.

[0069] The core controller of the aforementioned electrical control unit uses microcontrollers, PLCs, DSPs, ARMs, etc. The specific controller to be selected can be chosen according to actual needs.

[0070] The movement distance control of the crossbeam 110, the lifting control of the jacking structure 410, the opening and closing control of the retractable rear beam 300, the start and stop control of the rotation drive device 500, and the extension and retraction control of the outrigger mechanism 900 of the aforementioned retractable cable laying device can all be completed by manual judgment.

[0071] The movement distance control of the crossbeam 110 of the above-mentioned retractable cable laying device, the lifting control of the lifting structure 410, the opening and closing control of the retractable rear beam 300, the start and stop control of the rotation drive device 500, and the extension and retraction control of the outrigger mechanism 900 can also be accomplished by adding sensors.

[0072] Specifically, a height sensor can be installed to determine the height of the lifting structure 410; a displacement sensor can be installed to determine the distance between the two crossbeams 110; a pressure sensor or vision sensor can be installed to determine the connection status between the rotation drive device 500 and the cable reel 700; a switch unit can be installed to provide feedback on the opening and closing status of the retractable rear beam 300; and a vision sensor or lidar can be installed to determine the real-time position and status of the cable reel 700. There are many possible implementations, and this application does not impose any specific limitations.

[0073] In some implementations, reference Figure 1 The retractable cable deployment device also includes:

[0074] Outrigger mechanism 900 is mounted on telescopic front beam 200 and / or telescopic rear beam 300 and / or main crossbeam frame; control system 600 is used to adjust the telescopic distance of outrigger mechanism 900.

[0075] The aforementioned support leg mechanism 900 can level and support the entire retractable cable deployment device before the cable reel 700 is retracted or extended, to ensure stability and safety during use.

[0076] In some implementations, reference Figure 1 The outrigger mechanism 900 includes multiple controllable outriggers, which are mounted on the telescopic front beam 200 and the telescopic rear beam 300.

[0077] The aforementioned multiple controllable outriggers are mounted on the telescopic front beam 200 and the telescopic rear beam 300, enabling efficient leveling and support with a relatively small number of outriggers.

[0078] In some implementations, reference Figures 1 to 3 A mounting platform 1000 is installed on the retractable front beam 200, and a control system 600 is installed on the mounting platform 1000.

[0079] The aforementioned control system 600 requires a control and power source. In cases where the system is large in size, adding a mounting platform 1000 can better accommodate the entire control system 600 and facilitate integrated setup.

[0080] The aforementioned placement platform 1000 may be equipped with components that connect to the tractor head 800, so as to better connect the tractor head 800 to the retractable cable deployment device of this application embodiment.

[0081] In some implementations, reference Figures 2 to 5 The retractable front beam 200 includes:

[0082] Front beam main body 210;

[0083] The first front telescopic cylinder 220 is mounted on the front beam body 210, and one end is connected to a crossbeam 110.

[0084] The second front telescopic cylinder 230 is mounted on the front beam body 210, and one end is connected to another crossbeam 110.

[0085] The aforementioned front beam body 210 can be configured as a square tubular structure. Both the first front telescopic cylinder 220 and the second front telescopic cylinder 230 can have their main bodies housed within the square tubular structure, with the end not housed within the square tubular structure connected to the crossbeam 110. In this configuration, extending or retracting the first front telescopic cylinder 220 and the second front telescopic cylinder 230 can push the two crossbeams 110 to move in opposite directions.

[0086] In some implementations, an electric cylinder can be used to replace the first front telescopic cylinder 220 and the second front telescopic cylinder 230, or other structures with telescopic capabilities can be used, such as a lead screw structure. There are many specific options, and the configuration can be set according to the required driving force.

[0087] In some implementations, reference Figures 2 to 5 The retractable cable laying device also includes a rotating mechanism 340 controlled by the control system 600. Either end of the retractable rear beam 300 is connected to the crossbeam 110 through the rotating mechanism 340. The control system 600 is used to control the operation of the rotating mechanism 340 so that the retractable rear beam 300 can be opened or closed.

[0088] In this embodiment, the opening and closing operations are completed by rotating the retractable rear beam 300 to one side as a whole. This configuration is simple and provides good structural strength. Furthermore, it facilitates the installation of the first and second rear telescopic cylinders 320 and 330.

[0089] The aforementioned rotating mechanism 340 can be an electrically driven rotating structure or a rotating structure with other power sources. There are many specific implementation methods, and no further limitations are made in this embodiment.

[0090] The aforementioned rotating mechanism 340 can be manually rotated. In this case, manual assistance is required to open and close the retractable rear beam 300.

[0091] In some embodiments, the end of the telescopic rear beam 300 that is not connected to the rotating mechanism 340 can be detachably connected to the crossbeam 110.

[0092] It should be noted that in operation scenarios with a high degree of manual intervention, the detachable connection between the retractable rear beam 300 and the crossbeam 110 can be configured as a pin-type or snap-fit ​​structure. In scenarios requiring automatic control, a combination of microswitches and electric locks controlled by the electrical control unit in the control system 600 can be used. Specifically, the microswitch is installed on the crossbeam 110. When the retractable rear beam 300 is closed in place, it will trigger the microswitch, which will then cause the electric lock to complete the locking operation. Conversely, when it is necessary to open, the electric lock can be unlocked.

[0093] In some implementations, reference Figures 2 to 5 The retractable rear beam 300 includes:

[0094] Rear beam main body 310;

[0095] The first rear telescopic cylinder 320 is mounted on the rear beam body 310, and one end is connected to a crossbeam 110 via a rotating mechanism 340.

[0096] The second rear telescopic cylinder 330 is mounted on the rear beam body 310, and one end is detachably connected to another crossbeam 110.

[0097] The aforementioned rear beam main body 310 can be configured as a square tubular structure. Both the first and second rear telescopic cylinders 320 and 330 can be housed within this square tubular structure. The end of the first rear telescopic cylinder 320 not housed within the square tubular structure is connected to the crossbeam 110 via a rotating mechanism 340. The end of the second rear telescopic cylinder 330 not housed within the square tubular structure is detachably connected to the crossbeam 110. In this configuration, the entire telescopic rear beam 300 can be rotated via the rotating mechanism. Furthermore, when the telescopic rear beam 300 is closed, the extension or retraction of the first and second rear telescopic cylinders 320 can push the two crossbeams 110 to move towards or away from each other.

[0098] In some implementations, an electric cylinder can be used to replace the first rear telescopic cylinder 320 and the second rear telescopic cylinder 330, or other structures with telescopic capabilities can be used, such as a lead screw structure. There are many specific options, and the configuration can be set according to the required driving force.

[0099] In some implementations, reference Figures 2 to 3 Each support unit of 400 includes:

[0100] The main support column 420 is installed on the crossbeam 110;

[0101] The lifting frame 430 is mounted on the main support column 420 and can slide along the main support column 420.

[0102] The lifting drive device 440 is used to drive the lifting frame 430 to slide along the main support column 420;

[0103] The lifting structure 410 is mounted on the lifting frame 430.

[0104] In this embodiment, the lifting drive device 440 can drive the lifting frame 430 to slide along the main support column 420, thereby driving the lifting structure 410 set on the lifting frame 430 to move synchronously, and finally realize the alignment of the lifting structure 410 with the center structure of the cable reel 700.

[0105] The aforementioned lifting frame 430 can be slidably set up through a slide rail structure set on the main support column 420.

[0106] In some embodiments, the lifting structure 410 includes a top cone support rod rotatably mounted on the lifting frame 430.

[0107] In this embodiment, a rotating top cone support rod is provided to align and lift the cable reel 700 with the center structure, which can further increase the applicability of the telescopic cable laying device in this embodiment, and enable the cable reel 700, which does not have the ability to rotate, to achieve rotation control.

[0108] In some embodiments, the lifting drive device 440 includes a lifting cylinder.

[0109] In this embodiment, the use of a telescopic hydraulic cylinder can provide greater driving force, thereby enabling better lifting and rotation support operations of the cable reel 700.

[0110] In some implementations, reference Figures 2 to 3 The support mechanism 400 also includes an auxiliary support column 450, which is mounted on the crossbeam 110 and is used to assist in supporting the main support column 420.

[0111] In this embodiment, an auxiliary support column 450 is added, which can better support the cable reel 700 compared to the structure of setting a main support column 420 alone.

[0112] The auxiliary support column 450 and the main support column 420 can form an "A" shaped structure.

[0113] In some implementations, reference Figure 1 , Figure 6 , Figure 7 The rotation drive device 500 includes:

[0114] The base 510 is mounted on the retractable front beam 200;

[0115] An adjustable mounting bracket is mounted on the base 510;

[0116] A hydraulic drive wheel assembly is mounted on an adjustable mounting bracket; a control system 600 is used to drive the adjustable mounting bracket to adjust the position of the drive wheel 531 in the hydraulic drive wheel assembly, and to control the rotation of the drive wheel 531 in the hydraulic drive wheel assembly.

[0117] In this embodiment, the hydraulic drive wheel assembly uses drive wheel 531 as the drive structure, and the relative position of drive wheel 531 and cable reel 700 can be adjusted by adjustable mounting bracket, thereby realizing the driving and braking operation of cable reel 700.

[0118] The cable reel 700 is provided with a friction structure, and the drive wheel 531 is a friction wheel. Thus, when the friction wheel and the friction structure are in contact, the cable reel 700 can be driven and braked by friction.

[0119] The aforementioned adjustable mounting bracket allows for the separation of the drive wheel 531 from the cable reel 700 without the need for the drive wheel 531 to operate.

[0120] In some implementations, reference Figure 6 , Figure 7 The adjustable mounting bracket includes:

[0121] Two horizontal mounting arms 521 are both mounted on the base 510 and located at both ends of the base 510;

[0122] Two vertical pressure arms 522 are provided corresponding to two horizontal mounting arms 521, and one end of the vertical pressure arm 522 is hinged to the end of the horizontal mounting arm 521 away from the rear telescopic beam.

[0123] Two hydraulic telescopic cylinders 523 are correspondingly set with two horizontal mounting arms 521. One end is set on the horizontal mounting arm 521 or the base 510, and the other end is connected to the corresponding vertical pressure arm 522. The two hydraulic telescopic cylinders 523 are controlled by the control system 600.

[0124] The base 510 has mounting holes at both ends, and two horizontal mounting arms 521 can be fixed to the base 510 through the mounting holes, and the fixing method is parallel to the crossbeam 110.

[0125] After one end of the vertical pressure arm 522 is hinged to the end of the horizontal mounting arm 521 away from the telescopic rear beam 300, a rotatable connection can be achieved.

[0126] The aforementioned hydraulic telescopic cylinder 523 is fixed at one end to the horizontal mounting arm 521 and at the other end to the vertical pressure arm 522, thereby enabling the control system 600 to perform lifting and pressing operations on the vertical pressure arm 522 through the extension and retraction of the hydraulic telescopic cylinder.

[0127] The aforementioned hydraulic drive wheel assembly is located at the top of the vertical pressure arm 522, so that when the hydraulic telescopic cylinder performs the pressing operation, the drive wheel 531 can complete the contact with the friction structure of the cable reel 700 through the vertical pressure arm 522.

[0128] In some implementations, reference Figure 6 , Figure 7 A hydraulic drive wheel assembly, including:

[0129] Two sets of drive wheels 531 are respectively set at the upper ends of the two vertical pressure arms 522 and close to the telescopic rear beam;

[0130] Two sets of hydraulic motors 532 are respectively installed on the upper ends of the two vertical pressure arms 522, and are used to drive the corresponding drive wheels 531 to rotate through the transmission assembly 533.

[0131] Each set of drive wheels 531 contains two hollow rollers. The hollow rollers can be adjusted to the left and right and can be easily replaced as wear parts.

[0132] The two sets of drive wheels 531 on both sides can be connected by a transmission assembly 533, and two sets of hydraulic motors 532 are provided in the middle.

[0133] The aforementioned hydraulic drive wheel assembly may also include V-shaped bends 534 on both sides to better ensure good contact between the two drive wheels 531 on both sides and the friction structure of the cable reel 700.

[0134] During operation, power is provided by two sets of hydraulic telescopic cylinders 523 to adjust the angle between the horizontal mounting arm 521 and the vertical pressure arm 522, bringing them closer to the rim of the cable reel 700 and causing the four drive wheels 531 to press against the friction structure of the cable reel 700. The hydraulic motor 532 is started, driving the transmission component 533 through the chain, thereby realizing the movement of the drive wheels 531. The drive wheels 531 are driven by the hydraulic motor 532 to rotate in both directions. Relying on the pressure transmitted by the pressure arm component, a large frictional force is generated between the drive wheels 531 and the friction structure of the cable reel 700, thereby driving the cable reel 700 to rotate for cable laying, as well as the movement and stopping of the cable reel 700.

[0135] In some embodiments, the control system 600 includes:

[0136] The hydraulic drive system is used to provide a hydraulic drive source to drive the retractable rear beam 300 to open or close, drive the retractable rear beam 300 and / or the retractable front beam 200 to move towards or away from each other, drive the lifting structure 410 in the support mechanism 400 to rise and fall, and drive the rotary drive device 500 to operate.

[0137] An electrical control unit is used to control the hydraulic drive system to control the opening or closing of the telescopic rear beam 300, to control the telescopic rear beam 300 and / or the telescopic front beam 200 to extend and retract to adjust the spacing between the two crossbeams 110, to control the height of the lifting structure 410 in the two support mechanisms 400, and to control the rotation drive device 500 to drive the cable reel 700 supported by the two lifting structures 410 to rotate.

[0138] In this embodiment, a hydraulic drive source is used as the driving force, which can provide greater driving force compared to an electric drive method.

[0139] It is understandable that, in the operation of extending and retracting the retractable front beam 200 and the retractable rear beam 300, opening or closing the retractable rear beam 300, driving the retractable rear beam 300 and / or the retractable front beam 200 to move towards or away from each other, driving the lifting structure 410 in the support mechanism 400 to rise and fall, and driving the rotation drive device 500 to operate, when using hydraulic drive, the drive pump, hydraulic motor 532 and other components of the hydraulic drive system can be set around the corresponding execution structure or centrally set in the housing of the control system 600 system according to actual needs. It is also understandable that, in order to adapt to operations such as extension, lifting, and rotation, flexible or retractable pipelines can be selected according to actual needs.

[0140] In this embodiment, the main oil tank of the hydraulic drive system can be shared. The main oil tank is equipped with a filter screen inside to separate the oil suction and return. It is also equipped with a rod magnetic filter. The oil tank is a welded steel plate structure and is passivated and rust-proofed. The operation mode of the hydraulic station can include inching, continuous operation, manual control, and automatic control.

[0141] The aforementioned hydraulic drive system and electrical control unit can be powered by a diesel generator, and the motor can be a variable frequency speed control motor.

[0142] See Figure 8 As shown, Figure 8 This is a flowchart of a cable laying method provided in one embodiment of the present application. The cable laying method is used to control the above-mentioned retractable cable laying device, including steps S100 to S600.

[0143] S100 controls the retractable rear beam 300 to open, so that the main crossbeam frame and the retractable front beam 200 form an open structure, wherein the distance between the two crossbeams 110 in the open structure is greater than the width of the cable reel 700.

[0144] S200 controls the travel mechanism 120 to travel so that the cable reel 700 is located inside the opening structure, and the center structure of the cable reel 700 is parallel to the line connecting the two lifting structures 410 and coincides in the direction perpendicular to the main beam frame.

[0145] S300 controls the two lifting structures 410 to move in a direction perpendicular to the main crossbeam frame so that the two lifting structures 410 are directly facing the center structure of the cable reel 700.

[0146] S400 controls the extension and retraction of the telescopic rear beam 300 and / or the telescopic front beam 200 to adjust the spacing between the two crossbeams 110 so that the two lifting structures 410 abut against the central structure of the cable reel 700.

[0147] S500 controls the two lifting structures 410 to move in a direction perpendicular to the main crossbeam frame so that the cable reel 700 is suspended in the air.

[0148] S600 controls the rotation drive 500 to rotate the cable reel 700.

[0149] The cable laying method in this embodiment can be applied to electrical control units.

[0150] The cable laying method in this embodiment is based on the above-described retractable cable laying device, which has been described in detail above and will not be repeated here.

[0151] The opening of the aforementioned retractable rear beam 300 can be accomplished through the rotation mechanism 340. When automatic closing is required, a micro switch and an electric lock can be added. The specific implementation method has been described above and will not be repeated here.

[0152] The distance between the two crossbeams 110 in the above-mentioned open structure is greater than the width of the cable reel 700, so that when the tractor head 800 adjusts the retractable cable deployment device, the cable reel 700 can be placed inside the open structure.

[0153] The aforementioned retractable crossbeam 110 can be opened after the distance between the two crossbeams 110 has been adjusted.

[0154] The aforementioned control of the walking mechanism 120 can be achieved by directly controlling the walking mechanism 120 when it has the ability to walk actively, and by controlling the tractor head 800 when the walking mechanism 120 does not have the ability to walk actively.

[0155] The aforementioned control walking mechanism 120 can stop when the two lifting structures 410 and the central structure of the cable reel 700 are on the same vertical plane.

[0156] The process of controlling the movement of the two lifting structures 410 in a direction perpendicular to the main crossbeam frame requires stopping when the two lifting structures 410 are directly facing the center structure of the cable reel 700.

[0157] The process of controlling the walking mechanism 120 to move and controlling the lifting structure 410 to rise and fall can be completed with manual assistance. When automatic completion is required, the position of the cable reel 700 can be captured by a visual sensor and its relative position to the telescopic cable deployment device can be determined. At the same time, in order to better assist in lifting the cable reel 700, sensors for detecting the spacing of the crossbeam 110 and sensors for detecting the height of the lifting structure 410 can be added to determine the spatial position of the lifting structure 410.

[0158] Understandably, once the spatial position of the lifting structure 410 and the spatial position of the central structure of the cable reel 700 are determined, the lifting operation of the cable reel 700 to be operated can be completed quickly.

[0159] The aforementioned sensor for detecting the distance between the crossbeams 110 can be achieved by setting distance sensors on the two crossbeams 110, such as laser distance measuring or infrared distance measuring, or by adding displacement sensors to the telescopic cylinders of the telescopic front beam 200 and the rear beam to detect the extension and retraction of the piston rod in the cylinder.

[0160] The height detection sensor for the aforementioned lifting structure 410 can be obtained by directly using a displacement sensor and a distance sensor to detect the extension and retraction distance of the piston rod of the lifting cylinder.

[0161] A pressure sensor can be installed at the top of the aforementioned lifting structure 410. By collecting the pressure value between the lifting structure 410 and the central structure of the cable reel 700, it can be determined whether the two lifting structures 410 have effectively clamped the cable reel 700.

[0162] After the lifting structure 410 has effectively clamped the cable reel 700, it can control the two lifting structures 410 to move in a direction perpendicular to the main crossbeam frame. The specific distance of movement is such that the drive unit of the drive assembly can complete the drive operation on the cable reel 700.

[0163] Specifically, when using a friction wheel and setting a friction structure on the rim of the cable reel 700, the cable reel 700 needs to rise to effectively contact the friction wheel. Furthermore, if the rotation drive device 500 has the ability to adjust the position of the friction wheel, the cable reel 700 needs to rise to a height that allows it to rotate and allows the rotation drive device 500 to adjust the friction wheel to contact the friction structure.

[0164] The effective contact between the aforementioned cable reel 700 and the friction wheel can be determined by allowing the friction wheel and the friction structure to continue moving relative to each other for a certain period of time after they have made contact, or by detecting the frictional force between the friction wheel and the friction structure.

[0165] Understandably, after completing the lifting and cable laying operations of the cable reel 700, when it is necessary to return the cable reel 700 to be operated, the cable reel 700 can be lowered to the ground by controlling the lifting structure 410, then the two crossbeams 110 can be moved away, then the retractable rear beam 300 can be opened, and finally the tractor head 800 can be moved away from the retractable cable laying device and the retractable rear beam 300 can be closed.

[0166] In some implementations, prior to step S600, the following steps are also included:

[0167] Extend the outrigger mechanism 900 to level the retractable cable deployment device.

[0168] In this embodiment, the retractable cable deployment device is leveled using the support leg mechanism 900, which can provide better stability during subsequent exhibitions.

[0169] It should be noted that the outrigger extension and leveling process should be carried out without adjusting the spacing between the two crossbeams 110, in order to avoid the situation where the spacing between the crossbeams 110 cannot be adjusted due to the outriggers contacting the ground.

[0170] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
