[0015] See also Figures 1 to 7 As shown, an embodiment of the present application provides a retractable cable deployment device, which includes: The main crossbeam frame includes two parallel crossbeams 110 and a traveling mechanism 120 disposed under each crossbeam 110; a retractable front beam 200 connected between the front ends of the two cross beams 110; The retractable rear beam 300 is connected between the rear ends of the two cross beams 110; at least one of the retractable rear beam 300 and the retractable front beam 200 is used to actively adjust the distance between the two cross beams 110; the retractable rear beam 300 is configured as an openable and closable structure; Two support mechanisms 400 are respectively disposed on the two crossbeams 110. Each support mechanism 400 is provided 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 disposed opposite each other and are used to jointly rotate and support the cable drum 700. The rotation driving device 500 is provided on the telescopic front beam 200, the telescopic rear beam 300 or the main cross beam frame; a control system 600 for controlling the opening or closing of the retractable rear beam 300, controlling the extension and retraction of the retractable rear beam 300 and / or the retractable front beam 200 to adjust the distance between the two cross beams 110, controlling the height of the jacking structures 410 in the two support mechanisms 400, and controlling the rotation drive device 500 to drive the cable drum 700 rotatably supported by the two jacking structures 410; When the retractable rear beam 300 is opened, the main crossbeam frame and the retractable front beam 200 form an open structure.

[0016] In the embodiment of the present application, the tractor head 800 can be used to quickly transport the retractable cable deployment device, and it can be used directly without on-site assembly, hoisting and debugging, effectively improving the efficiency of cable laying. At the same time, the use of the retractable front beam 200 and the retractable tail beam can adapt to cable drums 700 of different specifications, which is convenient to operate. The cable drum 700 can be actively loaded and unloaded with the liftable support mechanism 400, eliminating the dependence on auxiliary equipment such as cranes. In addition, the retractable cable deployment device in the present application is simple to operate, has low requirements for the construction environment, roads and space, and occupies a small area. It is especially suitable for scenes where large hoisting equipment cannot enter, such as narrow streets, buildings or trees. It can be put into use upon arrival at the site, significantly improving construction convenience and emergency response capabilities.

[0017] The main crossbeam frame includes two parallel crossbeams 110 , and a group of running wheels as a running mechanism 120 is provided at the bottom of each crossbeam 110 , and each group of running wheels can be provided with at least two.

[0018] A groove structure may be provided in the middle of the crossbeam 110 to better assist in the setting of the support mechanism 400 .

[0019] The telescopic front beam 200 and the telescopic rear beam 300 can be telescoped in a direction in which the two cross beams 110 move closer to or away from each other.

[0020] It should be noted that at least one of the telescopic front beam 200 and the telescopic rear beam 300 has an active telescopic capability to provide power for moving the two beams 110 closer to or farther from each other.

[0021] The 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 controlled to open to form an open structure, and the main crossbeam frame can be moved by traction head 800 so that the cable reel 700 can be placed in the open structure.

[0022] The support mechanism 400 is arranged perpendicular to the beam 110 , so that the lifting structure 410 arranged in the support mechanism 400 can better achieve movement in a direction perpendicular to the beam 110 .

[0023] It is understandable that the lifting structures 410 on the two supporting mechanisms 400 can be raised and lowered synchronously to achieve alignment with the central structure of the cable drum 700 .

[0024] The central structure of the cable drum 700 can be brought into contact with the lifting structure 410 so that the cable drum 700 can be lifted and lowered when the two lifting structures 410 are lifted and lowered synchronously.

[0025] In actual operation, the traction head 800 moves the main crossbeam frame so that the cable drum 700 is in the open structure, and the central structure of the cable drum 700 is parallel to the line connecting the two jacking structures 410, and overlaps in the direction perpendicular to the main crossbeam frame. Then, the height of the jacking structure 410 can be adjusted to align the jacking structure 410 with the central structure of the cable drum 700. After alignment, the two parallel beams 110 are driven to move toward each other, so that the central structure of the cable drum 700 can be abutted against the jacking structure 410, and finally the cable drum 700 is clamped, so as to realize the lifting and lowering control of the cable drum 700.

[0026] The rotation driving device 500 may be disposed on any cross beam 110 or on the telescopic front beam 200 to drive the cable drum 700 to rotate.

[0027] The above-mentioned rotation drive device 500 can use a variety of drive forms. For example, a friction wheel can be used as a driving mechanism. By setting a friction structure that cooperates with the friction wheel on the cable drum 700, the cable drum 700 can be driven. Gears can also be used as a driving mechanism. By setting an engaging structure that cooperates with the gear on the cable drum 700, the cable drum 700 can be driven. Any other mechanism that can achieve driving can also be used. There are many specific driving forms. In actual engineering, they can be selected according to actual needs.

[0028] The friction structure can be obtained by directly setting a material or structure that increases friction on the rim of the cable drum 700 .

[0029] The above-mentioned 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 retractable front beam 200 and / or the retractable rear beam 300, provides a power source for the rotation drive device 500, provides a power source for the lifting and lowering of the jacking structure 410, provides a power source for the opening and closing of the retractable rear beam 300, and provides a power source for the movement of the support leg mechanism 900.

[0030] The above-mentioned drive system can be any one of a hydraulic drive system and an electric drive system, or a mixture of the two.

[0031] The core controller of the above-mentioned electrical control unit adopts a single chip microcomputer, PLC, DSP, ARM, etc. The specific controller can be selected according to actual needs.

[0032] The moving distance control of the crossbeam 110 of the above-mentioned retractable cable deployment device, 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 leg mechanism 900 can all be completed through manual judgment.

[0033] The moving distance control of the crossbeam 110 of the above-mentioned retractable cable deployment device, 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 leg mechanism 900 can also be completed by adding sensors.

[0034] Specifically, a height sensor may be provided to determine the height of the lifting structure 410, a displacement sensor may be provided to determine the distance between the two crossbeams 110, a pressure sensor or a visual sensor may be provided to determine the connection status between the rotation drive device 500 and the cable drum 700, a switch unit may be provided to provide feedback on the open and closed status of the retractable rear beam 300, and a visual sensor or a laser radar may be provided to determine the real-time position and status of the cable drum 700. There are many specific implementation methods, which are not specifically limited in this application.

[0035] In some embodiments, reference Figure 1 The retractable cable deployment device further comprises: The outrigger mechanism 900 is arranged on the telescopic front beam 200 and / or the telescopic rear beam 300 and / or the main crossbeam frame; the control system 600 is used to adjust the telescopic distance of the outrigger mechanism 900.

[0036] The leg mechanism 900 can level and support the entire retractable cable deployment device before the cable reel 700 is retracted or unfolded, so as to ensure stability and safety during use.

[0037] In some embodiments, reference Figure 1 The leg mechanism 900 includes a plurality of controllable legs, and the plurality of controllable legs are arranged on the telescopic front beam 200 and the telescopic rear beam 300.

[0038] The above-mentioned multiple controllable legs are arranged on the telescopic front beam 200 and the telescopic rear beam 300, which can achieve efficient leveling and support with a relatively small number of legs.

[0039] In some embodiments, reference Figures 1 to 3 A placement platform 1000 is provided on the retractable front beam 200 , and the control system 600 is provided on the placement platform 1000 .

[0040] The control system 600 needs to provide control and power sources. In the case of a large volume, adding a placement platform 1000 can better allow the control system 600 to be placed as a whole and facilitate integrated settings.

[0041] The placement platform 1000 may be provided with components connected to the tractor head 800 , so as to better connect the tractor head 800 to the retractable cable deployment device of the embodiment of the present application.

[0042] In some embodiments, reference Figures 2 to 5 , the retractable front beam 200 comprises: Front beam body 210; The first front telescopic cylinder 220 is provided on the front beam body 210 and one end of the cylinder is connected to a cross beam 110; The second front telescopic oil cylinder 230 is disposed on the front beam body 210 , and one end of the second front telescopic oil cylinder 230 is connected to the other cross beam 110 .

[0043] The front beam body 210 can be configured as a square tube structure. Both the first and second front telescopic cylinders 220 and 230 can be positioned within the square tube structure, with the ends not positioned within the square tube structure connected to the crossbeam 110. In this configuration, extending and retracting the first and second front telescopic cylinders 220 and 230 can propel the two crossbeams 110 toward or away from each other.

[0044] In some embodiments, an electric cylinder may be used to replace the first front telescopic cylinder 220 and the second front telescopic cylinder 230, or other structures with telescopic capabilities may be used to replace them, such as a screw structure. There are many specific options, and they can be set according to the driving force required.

[0045] In some embodiments, reference Figures 2 to 5 The retractable cable deployment device also includes a rotating mechanism 340 controlled by a 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 movement of the rotating mechanism 340 to open or close the retractable rear beam 300.

[0046] In this embodiment, the telescopic rear beam 300 is rotated to one side as a whole to complete the opening and closing operation. This configuration is simple and provides good structural strength. It also facilitates the installation of the first rear telescopic cylinder 320 and the second rear telescopic cylinder 330.

[0047] The above-mentioned rotating mechanism 340 can adopt an electric rotating structure or a rotating structure with other power sources. There are many specific implementation forms, which are not further limited in this embodiment.

[0048] The rotating mechanism 340 may be a manual rotating structure. In this case, manual assistance is required to complete the opening and closing of the telescopic rear beam 300.

[0049] 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 cross beam 110 .

[0050] It should be noted that in operation scenarios with more manual intervention, the detachable connection between the retractable rear beam 300 and the cross beam 110 can be set to a latch type, a snap-on type or other structure; in scenarios requiring automatic control, it can be completed using a combination of a micro switch and an electric lock controlled by the electrical control unit in the control system 600. Specifically, the micro switch is set on the cross beam 110. When the retractable rear beam 300 is closed into place, the micro switch will be triggered, which will allow the electric lock to complete the locking operation. Conversely, when it needs to be opened, the electric lock can be controlled to unlock.

[0051] In some embodiments, reference Figures 2 to 5 , retractable back beam 300, including: rear beam body 310; The first rear telescopic oil cylinder 320 is provided on the rear beam body 310 and one end of the cylinder is connected to a cross beam 110 via a rotating mechanism 340; The second rear telescopic oil cylinder 330 is disposed on the rear beam body 310 , and one end thereof is detachably connected to the other cross beam 110 .

[0052] The rear beam body 310 can be configured as a square tubular structure. Both the first and second rear telescopic cylinders 320 and 330 can be positioned within the square tubular structure. The end of the first rear telescopic cylinder 320 not positioned within the square tubular structure is connected to the crossbeam 110 via a rotation mechanism 340, while the end of the second rear telescopic cylinder 330 not positioned within the square tubular structure is detachably connected to the crossbeam 110. With this configuration, the rotation mechanism allows for the overall rotation of the telescopic rear beam 300. Furthermore, when the telescopic rear beam 300 is closed, the first and second rear telescopic cylinders 320 and 330 can extend or retract to push the two crossbeams 110 toward or away from each other.

[0053] In some embodiments, an electric cylinder may be used to replace the first rear telescopic cylinder 320 and the second rear telescopic cylinder 330, or other structures with telescopic capabilities may be used to replace them, such as a screw structure. There are many specific options, and they can be set according to the driving force required.

[0054] In some embodiments, reference Figures 2 to 3, each supporting mechanism 400 includes: The main support column 420 is provided on the crossbeam 110; The lifting frame 430 is provided on the main support column 420, and the lifting frame 430 can slide along the main support column 420; A lifting drive device 440 is used to drive the lifting frame 430 to slide along the main support column 420; The lifting structure 410 is disposed on the lifting frame 430 .

[0055] In this embodiment, the lifting drive device 440 can drive the lifting frame 430 to slide along the main support column 420, and then drive the jacking structure 410 set on the lifting frame 430 to move synchronously, and finally achieve the alignment of the jacking structure 410 and the central structure of the cable reel 700.

[0056] The lifting frame 430 can be slidably arranged by a slide rail structure arranged on the main support column 420 .

[0057] In some embodiments, the lifting structure 410 includes a top cone support rod rotatably disposed on a lifting frame 430 .

[0058] In this embodiment, a rotatable top cone support rod is provided to achieve alignment and lifting with the central structure of the cable drum 700, which can further increase the scope of application of the retractable cable deployment device in this embodiment and enable the cable drum 700 that does not have the ability to rotate to also achieve rotation control.

[0059] In some embodiments, the lifting drive device 440 includes a lifting cylinder.

[0060] In this embodiment, the use of a telescopic oil cylinder can provide a greater driving force, thereby better realizing the lifting operation and the rotation support operation of the cable drum 700.

[0061] In some embodiments, reference Figures 2 to 3 The support mechanism 400 further includes an auxiliary support column 450 , which is disposed on the beam 110 and is used to auxiliary support the main support column 420 .

[0062] In this embodiment, the auxiliary support column 450 is additionally provided, which can better support the cable reel 700 compared to the structure in which the main support column 420 is provided alone.

[0063] The auxiliary support column 450 and the main support column 420 may form an “A”-shaped structure.

[0064] In some embodiments, reference Figure 1 、 Figure 6 、 Figure 7 , the rotation driving device 500 includes: A base 510 is provided on the retractable front beam 200; An adjustable mounting bracket is provided on the base 510; The hydraulic drive wheel assembly is arranged on an adjustable mounting bracket; the 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.

[0065] In this embodiment, the hydraulic drive wheel assembly uses the drive wheel 531 as the drive structure, and the drive wheel 531 can adjust the relative position of the drive wheel 531 and the cable drum 700 through an adjustable mounting bracket, thereby realizing the driving and braking operations of the cable drum 700.

[0066] The cable drum 700 is provided with a friction structure, and the driving wheel 531 is a friction wheel. When the friction wheel abuts against the friction structure, the cable drum 700 can be driven and braked by utilizing friction force.

[0067] The adjustable mounting bracket can realize the separation operation of the driving wheel 531 and the cable drum 700 when the driving wheel 531 is not required to perform the driving operation.

[0068] In some embodiments, reference Figure 6 、 Figure 7 , adjustable mounting bracket includes: Two horizontal mounting arms 521 are both mounted on the base 510 and located at both ends of the base 510; Two vertical pressing arms 522 are provided corresponding to the two horizontal mounting arms 521, and one end of the vertical pressing arm 522 is hinged to the end of the horizontal mounting arm 521 away from the rear telescopic beam; Two hydraulic telescopic cylinders 523 are arranged corresponding to the two horizontal mounting arms 521 , one end of which is arranged 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 .

[0069] Mounting holes are provided at both ends of the base 510 , and the two horizontal mounting arms 521 can be fixed to the base 510 through the mounting holes in a manner parallel to the crossbeam 110 .

[0070] One end of the vertical pressing arm 522 is hinged to the end of the horizontal mounting arm 521 away from the retractable rear beam 300 to achieve a rotational connection.

[0071] One end of the hydraulic telescopic cylinder 523 is fixed on the horizontal mounting arm 521 , and the other end is fixed on the vertical pressing arm 522 , so that the control system 600 can complete the lifting and pressing operations of the vertical pressing arm 522 through the extension and retraction of the hydraulic telescopic cylinder.

[0072] The hydraulic driving wheel assembly is arranged at the top of the vertical pressing arm 522 , so that when the hydraulic telescopic cylinder performs a downward pressing operation, the driving wheel 531 can be brought into contact with the friction structure of the cable drum 700 through the vertical pressing arm 522 .

[0073] In some embodiments, reference Figure 6 、 Figure 7 , hydraulic drive wheel assembly, comprising: Two sets of driving wheels 531 are correspondingly arranged at the upper ends of the two vertical pressing arms 522 and are arranged close to the telescopic rear beam; Two sets of hydraulic motors 532 are correspondingly arranged at the upper ends of the two vertical pressure arms 522, and are used to drive the corresponding driving wheels 531 to rotate through the transmission assembly 533.

[0074] Each set of driving wheels 531 mentioned above includes two hollow rollers, the positions of which can be adjusted left and right, and can be easily replaced as wearing parts.

[0075] The two sets of driving wheels 531 on both sides can be connected through a transmission assembly 533, and two sets of hydraulic motors 532 are provided in the middle.

[0076] The hydraulic drive wheel assembly may further include V-shaped bent plates 534 provided on both sides to better ensure good contact between the two drive wheels 531 on both sides and the friction structure of the cable drum 700 .

[0077] 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 pressing arm 522, approach the rim of the cable drum 700, and make the four driving wheels 531 close to the friction structure of the cable drum 700; the hydraulic motor 532 is started, and the transmission assembly 533 is driven by the chain to realize the movement of the driving wheel 531, and the driving wheel 531 is driven by the hydraulic motor 532 to rotate forward and reverse. Relying on the pressure transmitted by the pressing arm assembly, a large friction force is generated between the driving wheel 531 and the friction structure of the cable drum 700, thereby driving the cable drum 700 to rotate to deploy the cable, as well as move and stop the cable drum 700.

[0079] In this embodiment, a hydraulic drive source is used as the driving force, which can provide a greater driving force than an electric drive method.

[0080] It can be understood that for the telescopic operation of the telescopic front beam 200 and the telescopic rear beam 300, the operation of opening or closing the telescopic rear beam 300, the operation of driving the telescopic rear beam 300 and / or the telescopic front beam 200 to move toward or away from each other, the operation of driving the lifting structure 410 in the support mechanism 400 to rise and fall, and the operation of driving the rotation drive device 500 to operate, when hydraulic drive is used, the driving pump, hydraulic motor 532 and other devices of the hydraulic drive system can be arranged around the corresponding execution structure or concentrated in the outer shell of the control system 600 according to actual needs. It can be understood that in order to adapt to operations such as telescopic, lifting, and rotation, flexible or telescopic pipelines can be selected according to actual needs.

[0081] In this embodiment, the main oil tank of the hydraulic drive system can be shared. A filter is set inside the main oil tank to separate the suction oil and the return oil. A rod-type magnetic filter is also set. The oil tank is a steel plate welded structure and is passivated and rust-proofed. The operation modes of the hydraulic station can include inching, linkage, manual control, and automatic control.

[0082] The 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.

[0083] See also Figure 8 As shown, Figure 8 Flowchart of a cable deployment method provided by one embodiment of the present application, the cable deployment method is used to control the above-mentioned retractable cable deployment device, including steps S100 to S600; S100, controlling 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 drum 700; S200, controlling the traveling mechanism 120 to travel so that the cable drum 700 is located in the opening structure and the center structure of the cable drum 700 is parallel to the line connecting the two jacking structures 410 and coincides with the direction perpendicular to the main crossbeam frame; S300, controlling the two jacking structures 410 to move in a direction perpendicular to the main crossbeam frame so that the two jacking structures 410 face the central structure of the cable drum 700; S400, controlling the telescopic rear beam 300 and / or the telescopic front beam 200 to extend and retract to adjust the distance between the two cross beams 110 so that the two lifting structures 410 abut against the central structure of the cable drum 700; S500, controlling the two lifting structures 410 to move in a direction perpendicular to the main beam frame so that the cable drum 700 is suspended in the air; S600 , controlling the rotation driving device 500 to move, so as to drive the cable drum 700 to rotate.

[0084] The cable deployment method in the embodiment of the present application can be applied to an electrical control unit.

[0085] The cable deployment method in the embodiment of the present application is implemented based on the above-mentioned retractable cable deployment device. The retractable cable deployment device has been described in detail above and will not be repeated here.

[0086] The above-mentioned control of opening the retractable rear beam 300 can be completed by the rotating mechanism 340. When an automatic closing operation is required, a micro switch and an electric control lock can be added. The specific implementation method has been described above and will not be repeated here.

[0087] The distance between the two crossbeams 110 in the above-mentioned opening structure is greater than the width of the cable drum 700, so that the cable drum 700 can be placed in the opening structure when the tractor head 800 adjusts the retractable cable unfolding device.

[0088] The telescopic beams 110 can be opened after adjusting the distance between the two beams 110 .

[0089] The above-mentioned control of the walking of the walking mechanism 120 can be completed by directly controlling the walking mechanism 120 when the walking mechanism 120 has the active walking ability. When the walking mechanism 120 does not have the active walking ability, the walking control of the walking mechanism 120 can be completed by controlling the tractor head 800.

[0090] The above-mentioned control walking mechanism 120 can stop during its walking process when the two lifting structures 410 and the central structure of the cable drum 700 are in the same vertical plane.

[0091] The above-mentioned process of controlling the two jacking structures 410 to move in a direction perpendicular to the main crossbeam frame needs to stop when the two jacking structures 410 are facing the central structure of the cable drum 700.

[0092] The above-mentioned process of controlling the movement of the walking mechanism 120 and controlling the lifting and lowering of the jacking structure 410 can be completed through manual assisted judgment; if automatic completion is required, a visual sensor can be used to capture the position of the cable reel 700 and determine the relative position with the retractable cable deployment device to complete it. At the same time, in order to better assist in the lifting of the cable reel 700, a sensor for detecting the spacing between the beams 110 and a sensor for detecting the height of the jacking structure 410 can be added to determine the spatial position of the jacking structure 410.

[0093] It is understandable that after determining the spatial position of the lifting structure 410 and the spatial position of the central structure of the cable reel 700 , the lifting operation of the cable reel 700 to be operated can be quickly completed.

[0094] The above-mentioned sensor for detecting the distance between the beams 110 can be completed by setting a distance measuring sensor on the two beams 110, such as laser distance measurement, infrared distance measurement, etc., or it can be determined by adding a displacement sensor to the telescopic cylinder of the telescopic front beam 200 and the rear beam to detect the telescopic amount of the piston rod in the cylinder.

[0095] The sensor for detecting the height of the jacking structure 410 can directly detect the telescopic distance of the piston rod of the lifting cylinder by using a displacement sensor and a distance measuring sensor.

[0096] A pressure sensor may be provided at the top of the jacking structure 410 to collect the pressure value between the jacking structure 410 and the central structure of the cable drum 700 to determine whether the two jacking structures 410 have completed the effective clamping of the cable drum 700.

[0097] After the above-mentioned lifting structures 410 complete the effective clamping of the cable reel 700, the two lifting structures 410 can be controlled to move in a direction perpendicular to the main crossbeam frame, and the specific distance of movement is until the driving part of the driving assembly can complete the driving operation of the cable reel 700.

[0098] Specifically, when a friction wheel is used and a friction structure is provided on the rim of the cable drum 700, the cable drum 700 needs to be raised to effectively abut against the friction wheel. Furthermore, when the rotating drive device 500 has the ability to adjust the position of the friction wheel, the cable drum 700 needs to be raised to a height at which it can rotate and allow the rotating drive device 500 to adjust the friction wheel to abut against the friction structure.

[0099] The effective contact between the cable drum 700 and the friction wheel can be determined by continuing the relative motion of the friction wheel and the friction structure for a certain period of time after the friction wheel and the friction structure contact each other, or by detecting the friction force between the friction wheel and the friction structure.

[0100] It is understandable that after completing the lifting operation of the cable drum 700 and the cable deployment operation, when it is necessary to put the cable drum 700 back, the cable drum 700 can be lowered to the ground by controlling the jacking structure 410, and then the two cross beams 110 are moved away, and then the retractable rear beam 300 is opened, and finally the tractor head 800 removes the retractable cable deployment device and closes the retractable rear beam 300.

[0101] In some implementations, before step S600, the method further includes: The leg mechanism 900 is controlled to extend to level the retractable cable deployment device.

[0102] In this embodiment, the telescopic cable deployment device is leveled using the leg mechanism 900 , which can provide better stability during subsequent deployment.

[0103] It should be noted that the leg extension and leveling process needs to be performed without adjusting the distance between the two beams 110 to avoid the situation where the distance between the beams 110 cannot be adjusted due to the legs contacting the ground.

[0104] The above is only a specific implementation method of the present application. Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited to this. Any technician familiar with this technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the scope of protection of this application.
