[0014] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.

[0015] See also Figures 1 to 10As shown, an embodiment of the present application provides a lightweight wiring system, which includes: Each of the four cable deployment components includes a base 1100, a main lifting arm 1200, a roller mechanism 1300, and a telescopic device 1400. The main lifting arm 1200 is rotatably mounted on the base 1100. The roller mechanism 1300 is mounted on the main lifting arm 1200, with the rotation plane of the roller mechanism 1300 being perpendicular to the plane of the base 1100. The telescopic device 1400 is mounted on the base 1100 and is used to adjust the rotation angle of the main lifting arm 1200, thereby adjusting the height of the roller mechanism 1300. The cable traction device for a cable channel includes a main frame 2100, a fixing assembly 2200, a driving mechanism 2300, a front support assembly 2400, a spacing adjustment bracket 2500, and a traction control system 2800. Two first running mechanisms 2110 are provided on both sides of the bottom of the main frame 2100. The fixing assembly 2200 is provided on the main frame 2100. The driving mechanism 2300 is provided on the main frame 2100 and is used to drive the two first running mechanisms 2110. Two second running mechanisms 2410 are provided on both sides of the bottom of the front support assembly 2400. Space for the cable 1810 to pass through is provided between the two second running mechanisms 2410 and between the two first running mechanisms 2110. The top of the front support assembly 2400 is rotatably connected to the top of the main frame 2100. The spacing adjustment bracket 2500 is used to adjust the angle between the front support assembly 2400 and the main frame 2100. The traction control system 2800 is electrically connected to the driving mechanism 2300. Multiple auxiliary wiring devices 3000 are at least used to achieve rolling support for the cable 1810.

[0016] In the embodiment of the present application, a small transfer vehicle can be used to easily transfer the cable deployment components, the cable traction equipment for the cable channel, and the auxiliary wiring equipment 3000. Compared with traditional large-scale integrated equipment, it can complete the transportation in a smaller area or effectively reduce the difficulty of transportation; at the same time, the four cable deployment components adopt a component collaborative cable deployment working mode, so that each cable deployment component can be arranged separately during the layout phase, and the cable can be deployed collaboratively during the cable deployment operation, effectively reducing the requirements for site occupation while meeting the cable deployment needs; and the cable traction equipment for the cable channel is designed to be lightweight and foldable, so that it can enter the narrow cable channel through the narrow downhole channel to complete the cable 1810 traction work. In the embodiment of the present application, through modularization, lightweight design and folding design to adapt to narrow spaces, the entire lightweight wiring system can be easily transported in a complex environment, and the cable 1810 traction and laying can be easily completed in a small space, effectively reducing the demand for manpower, greatly improving the laying efficiency, and reducing the possibility of accidents due to manual operation.

[0017] The base 1100 can be placed horizontally on the ground. It can be equipped with components for transporting by forklifts or other transport equipment, allowing for flexible transportation. Specifically, the base 1100 can be configured to allow for direct lifting by a forklift, or to be hoisted using a small lifting tool such as a hoisting hoist. Alternatively, a combination of these structures can be used to improve applicability.

[0018] The main lifting arm 1200 rotates in the direction of approaching and moving away from the base 1100, so as to allow the roller mechanism 1300 to adjust its height, thereby achieving the lifting and rotation support of the cable drum 1800. The rotation plane of the main lifting arm 1200 is perpendicular to the plane of the base 1100.

[0019] The roller mechanism 1300 may include a roller and a bearing supporting the roller, wherein the bearing is provided on the main lifting arm 1200. It will be appreciated that the roller needs to have a sufficient width so that the rim of the cable drum 1800 can be placed on the roller.

[0020] The telescopic device 1400 is disposed between the base 1100 and the main lifting arm 1200 and can be extended and retracted, thereby rotating the main lifting arm 1200 and adjusting the height of the roller. The telescopic device 1400 can be implemented in a variety of ways, such as an electric telescopic device 1400 or a hydraulic telescopic device 1400. A variety of devices are available for achieving telescopic movement, and a flexible selection can be made based on actual needs.

[0021] The above-mentioned cable spreading assemblies need to be used in combination of four, and the four cable spreading assemblies are respectively used to lift the rim of the cable drum 1800 to complete the lifting and rotation support of the cable drum 1800.

[0022] Specifically, refer to Figure 4 When the cable unfolding assembly is needed, the cable unfolding assembly can be transferred to the rim of the cable drum 1800 and abutted against the rim, and the roller mechanism 1300 is perpendicular to the rim. The four cable unfolding assemblies are respectively abutted against the rims on both sides of the cable drum 1800, and the two cable unfolding assemblies on the same side are arranged opposite to each other. Afterwards, the four telescopic devices 1400 are controlled to lift synchronously to lift the cable drum 1800. Then, the cable drum 1800 is driven to rotate or the cable 1810 in the cable drum 1800 is pulled by a traction device to realize the cable unfolding and retracting operation of the cable 1810.

[0023] It is understandable that when it is necessary to use four cable deployment components to collaboratively complete the lifting of the cable reel 1800, the lifting operation of the cable reel 1800 can be completed by manual adjustment one by one or collaborative adjustment by multiple people, or the four cable deployment components can be connected to an external control system, and the electronic lifting control can be completed by setting sensors to detect the inclination and height of the cable reel 1800. For example, a height sensor is used to detect whether the cable reel 1800 has detected a certain height to determine whether it can be rotated, and a tilt sensor is used to detect the degree of tilt, so that the four cable deployment components can be lifted synchronously to avoid the cable reel 1800 from tilting.

[0024] The above-mentioned main frame 2100 can be set to a "7" shape, and a traction control system 2800 can be set on the top of the "7"-shaped structure to facilitate operation by construction workers. The driving mechanism 2300 can be placed in the middle part of the "7" shape to be connected to the first walking mechanism 2110 for transmission.

[0025] The fixing assembly 2200 may be disposed on a side of the main frame 2100 away from the front support assembly 2400 , or may be disposed at other locations that are convenient for connecting the cable 1810 .

[0026] The driving mechanism 2300 may be hydraulically driven, electrically driven, or other driving structures that can drive the first walking mechanism 2110 .

[0027] A second running mechanism 2410 is disposed at the bottom of the front support assembly 2400. The second running mechanism 2410 can be configured as a guide wheel structure, for example, a conventional universal wheel structure. The first running mechanism 2110 needs to be able to actively move, and thus can utilize a wheel body that is larger and easier to connect to the transmission mechanism. In some embodiments, to facilitate steering, an electrically controlled rotation assembly can be provided at the connection between the first running mechanism 2110 and the drive mechanism 2300 to adjust the rotation angle of the wheel body.

[0028] Sufficient height and width must be reserved between the two first running mechanisms 2110 to allow the auxiliary wiring device 3000 to pass through, and to allow the cable 1810 to pass through if it is large. It is understood that the two second running mechanisms 2410 also need to reserve space for the auxiliary wiring device 3000 to pass through.

[0029] The auxiliary wiring equipment 3000 may include a pulley, an electric pulley, a sliding support frame and other equipment.

[0030] The top of the above-mentioned front-end support assembly 2400 and the main base 2100 can be rotated, thereby providing a basis for the cable traction device for the entire cable channel to be folded and normally unfolded, and the spacing adjustment bracket 2500 can adjust the relative rotation angle of the front-end support assembly 2400 and the main base 2100, so that the cable traction device for the cable channel can maintain sufficient stability in its shape after normal unfolding, so as to complete the subsequent traction of the cable 1810.

[0031] There are many implementation forms of the above-mentioned spacing adjustment bracket 2500. For example, it can be a telescopic rod structure with damping, a latch-type connecting rod fixing structure, or a foldable bracket structure. The specific implementation forms are diverse and can be selected according to actual needs.

[0032] The above-mentioned traction control system 2800 mainly realizes the walking control of the cable traction equipment for the cable channel. For example, it can be wirelessly connected to the remote control device, and then the operator completes the walking control of the cable traction equipment for the cable channel through the remote control device. It can also be that an image acquisition device is set on the cable traction equipment for the cable channel, and the position of the auxiliary wiring device 3000 on the wiring path is obtained through the image acquisition device to realize automatic walking control.

[0033] The core controller of the traction control system 2800 can be a single chip microcomputer, DSP, PLC, etc. The specific selection can be made according to actual needs, for example, a Siemens S7 series PLC, an STM32 series processor, etc.

[0034] In some embodiments, at least one cable deployment assembly further includes a driving device 1700 , which is disposed on the main lifting arm 1200 and is configured to drive the roller mechanism 1300 to rotate.

[0035] The drive device 1700 transforms the cable-sprung assembly from a passively supported rotational structure to an actively driven rotational structure, eliminating the need for an external drive device to drive the cable drum 1800. When four cable-sprung assemblies are operating in coordination, the drive device 1700 can be configured for two cable-sprung assemblies on the same side.

[0036] The drive device 1700 can be in various forms, for example, a hydraulic drive system 1420 or an electrical drive system. The specific drive form can be flexibly selected so long as it can drive the cable reel 1800. When the drive device 1700 uses a drive motor, the control method is simpler and more accurate control precision can be provided.

[0037] The driving device 1700 can be connected to the traction control system 2800 by communication, so that the deployment speed of the driving device 1700 can be adapted to the travel speed of the cable traction device for the cable channel.

[0038] In some embodiments, reference Figure 4 、 Figure 10 , the lightweight wiring system also includes: The cable deployment control system 1900 is electrically connected to the driving device 1700 ; the cable deployment control system 1900 is communicatively connected to the traction control system 2800 .

[0039] The core controller of the cable deployment control system 1900 can be a single chip microcomputer, DSP, PLC, etc. The specific selection can be made according to actual needs, for example, a Siemens S7 series PLC, an STM32 series processor, etc.

[0040] The cable deployment control system 1900 can be communicatively connected with the traction control system 2800 , and can adaptively adjust the rotational speed of the roller mechanism 1300 driven by the driving device 1700 after acquiring the current walking speed transmitted by the traction control system 2800 .

[0041] In some embodiments, reference Figure 4 、 Figure 10 , the lightweight wiring system also includes: The posture detection unit 1910 is provided on the cable drum 1800 and is used to detect the posture information of the cable drum 1800 ; the cable deployment control system 1900 is electrically connected to the posture detection unit 1910 and the four telescopic devices 1400 .

[0042] In this embodiment, during the lifting process of cable drum 1800, the posture information detected by the posture detection unit is used as a feedback parameter for feedback adjustment. This ensures that the rim height of the cable deployment assembly on the lifted side is always balanced with that on the other side, preventing significant tilt. After cable drum 1800 is lifted to the preset cable deployment height and is relatively horizontal, cable drum 1800 is driven to rotate to achieve the cable deployment and retraction operation of cable 1810.

[0043] The above-mentioned posture detection unit 1910 can include any one of sensors such as a tilt sensor, a ranging sensor, etc. The specific selection form is not limited. The detection data can be used to determine whether the cable reel 1800 has an angle tilt in the horizontal direction due to excessive or insufficient lifting distance of a certain cable deployment component.

[0044] In some embodiments, the above-mentioned posture detection unit 1910 can directly use a tilt sensor. Directly using the tilt sensor to obtain tilt data can effectively reduce the amount of calculation and reduce the requirements for the core controller of the cable deployment control system 1900 compared to other methods that require conversion.

[0045] The above-mentioned posture detection unit 1910 can be set on a support surface selected at the central axis position of the cable drum 1800 for installation.

[0046] In some embodiments, reference Figure 10 , a cable pulling device for a cable channel, further comprising: The traction force detection unit 2810 is electrically connected to the traction control system 2800 and is used to detect traction force information when the cable 1810 is pulled by the cable pulling device in the cable channel.

[0047] In this embodiment, a traction force detection unit 2810 is added to detect the traction force of the cable 1810 pulled by the cable traction device for the cable channel. By obtaining the traction force information of the cable 1810 pulled by the cable traction device for the cable channel, it can be determined whether the cable traction device for the cable channel is pulling too fast or too fast, or whether the driving device 1700 is extending the cable too fast or too slow based on the traction force information. Therefore, when the traction force increases, the cable extending speed of the driving device 1700 can be increased, and when the traction force decreases, the cable extending speed of the driving device 1700 can be reduced.

[0048] In some embodiments, reference Figure 4 The above-mentioned lightweight wiring system further includes: The four groups of connecting rods 1120 are used to connect the bases 1100 of two adjacent cable spreading assemblies when the roller mechanisms 1300 of the four cable spreading assemblies abut against the rims of the cable drum 1800 .

[0049] In this embodiment, in order to prevent the four cable spreading assemblies from moving when working together, a connecting rod 1120 can be set between the four cable spreading assemblies. The connecting rod 1120 can be set after the four cable spreading assemblies are all abutted against their respective relative wheel rims.

[0050] In some embodiments, reference Figure 4 Each set of connecting rods 1120 is configured as a connecting rod with adjustable length.

[0051] In this embodiment, the connecting rods 1120 are all set as adjustable length connecting rods. There is no need to set different connecting rods 1120 for cable reels 1800 of different specifications. This can improve the reuse rate of the connecting rods 1120, reduce costs, and make it more convenient to carry.

[0052] In some embodiments, the adjustable length link includes a first link and a second link, and the first link and the second link are both provided with multiple length adjustment holes along the length direction, and the first link and the second link are adjusted in length through the multiple length adjustment holes.

[0053] The first connecting rod can be configured as a pipe, and the second connecting rod can extend into the pipe to improve the connection strength between the first connecting rod and the second connecting rod. The second connecting rod can also be configured as a pipe, which can further improve the strength of the second connecting rod while reducing the overall weight of the connecting rod 1120.

[0054] The base 1100 is provided with a combined connecting portion that cooperates with the connecting rod 1120 . The combined connecting portion is used to connect two adjacent cable deployment assemblies through the connecting rod 1120 .

[0055] The combined connection portion may be configured as a plurality of connection holes, and corresponding through holes are provided at both ends of the connection rod 1120 so as to complete the connection between the base 1100 and the connection rod 1120 by means of bolt fasteners.

[0056] In some embodiments, the telescoping device 1400 includes: The lifting cylinder 1410 has one end rotatably mounted on the base 1100 and the other end rotatably connected to the main lifting arm 1200. The rotation plane of the lifting cylinder 1410 is parallel to the rotation plane of the main lifting arm 1200. The hydraulic drive system 1420 electrically connected to the cable deployment control system 1900 is disposed on the base 1100 and is used to drive the lifting cylinder 1410 to extend and retract.

[0057] The lifting cylinder 1410 needs to be rotatably connected to the base 1100 and the main lifting arm 1200 to cooperate with the rotation operation of the main lifting arm 1200.

[0058] Specifically, one side of the lift cylinder 1410's cylinder body is rotatably connected to the base 1100, and the piston rod is rotatably connected to the main lift arm 1200, enabling rotation of the main lift arm 1200 via the retractable piston rod. Furthermore, with the cylinder body positioned at the bottom and the piston rod positioned at the top, the center of gravity of the entire cable deployment assembly can be lowered to a certain extent. It is understood that rotation of the main lift arm 1200 can also be achieved by inverting the lift cylinder 1410, but this arrangement would raise the center of gravity.

[0059] The hydraulic drive system 1420 primarily provides a hydraulic power source to drive the lift cylinder 1410 to extend and retract. Specifically, the hydraulic drive system 1420 may include an electric hydraulic pump, an electronically controlled valve, and the like. The electric hydraulic pump can be started and stopped under the control of the cable deployment control system 1900. The electronically controlled valve can be operated by the cable deployment control system 1900 to inject oil into the rod chamber and rodless chamber of the lift cylinder 1410 to achieve extension and retraction of the piston rod.

[0060] In some embodiments, the telescopic device 1400 further includes: The pressure detection unit is connected to the cable deployment control system 1900 and is used to detect the pressure of the lifting cylinder 1410.

[0061] In this embodiment, a pressure detection unit is provided, so that the cable deployment control system 1900 can better realize the lifting and lowering control of the cable reel 1800 when obtaining the pressure data detected by the pressure detection unit. That is, it can reduce the occurrence of excessive oil pressure in a single cable deployment component and balance the oil pressure as much as possible.

[0062] In some embodiments, reference Figures 1 to 3 The main lifting arm 1200 is set as a "7"-shaped support arm. One end of the main lifting arm 1200 is hinged to the base 1100, and the lifting cylinder 1410 is located on the inner side of the main lifting arm 1200.

[0063] In this embodiment, the use of a "7"-shaped support arm allows the entire cable deployment assembly to support heavy weight while effectively reducing its overall volume, achieving a lightweight design. Furthermore, the "7"-shaped support arm facilitates the telescopic operation of the telescopic device 1400 and better supports the main lifting arm 1200.

[0064] In some embodiments, the base 1100 is provided with two parallel slot structures 1110 .

[0065] In this embodiment, by providing two parallel slot structures 1110, a basis for insertion, removal and transfer is provided for the forklift equipment, making it easier for the operator to operate the forklift equipment to quickly complete the transfer operation.

[0066] In some embodiments, reference Figures 1 to 3 The two slot structures 1110 are disposed on both sides of the base 1100 and are arranged perpendicular to the roller mechanism 1300 .

[0067] In this embodiment, two slot structures 1110 are set on both sides of the base 1100 and arranged perpendicular to the roller mechanism 1300, so that the operator can better maintain a straight line with the center of the entire cable spreading assembly when transferring the cable spreading assembly, thereby better realizing the abutment operation between the roller mechanism 1300 in the cable spreading assembly and the rim of the cable reel 1800.

[0068] In some embodiments, reference Figures 1 to 3 A limiting structure 1520 is provided on the base 1100, and a top rod structure 1510 is provided on the main lifting arm 1200. The top rod structure 1510 is arranged toward the limiting structure 1520. The limiting structure 1520 is used to limit the movement of the top rod structure 1510 after the top rod structure 1510 contacts the limiting structure 1520.

[0069] The above-mentioned top rod structure 1510 is arranged toward the limiting structure 1520 on the base 1100, so that when a problem occurs with the telescopic device 1400 supporting the main lifting arm 1200, the main lifting arm 1200 can be supported. That is, because of the existence of the top rod structure 1510 and the limiting structure 1520, the main lifting arm 1200 can be supported when the main lifting arm 1200 suddenly drops, thereby avoiding accidents such as the cable reel 1800 tipping over.

[0070] The above-mentioned top rod structure 1510 is rotatably connected to the main lifting arm 1200, and is equipped with a state limiting structure. That is, the top rod structure 1510 can be limited to a certain rotation angle through the state limiting structure, or in the direction toward the limiting structure 1520 or away from the limiting structure 1520, so as to better take into account the jacking operation and the anti-fall operation.

[0071] The above-mentioned state limiting structure can select limiting parts such as pins, and by opening multiple through holes on the main lifting arm 1200 and the top rod structure 1510, the pins can be used to limit the top rod structure 1510 at different angles. It is also possible to directly select a rotation damper, and by arranging the damper on the rotation center of the top rod structure 1510, the top rod structure 1510 can be supported by damped rotation. It is also possible to directly adopt a torsion spring structure and directly use the torsion spring to limit the top rod structure 1510. For example, when the torsion spring is normally expanded, the top rod structure 1510 can face the limiting structure 1520, and when twisted, it can stay away from the limiting structure 1520.

[0072] The above-mentioned limiting structure 1520 can be set as a plurality of continuous limiting grooves to better limit the top rod structure 1510.

[0074] In this embodiment, when the main lifting arm 1200 is configured as a "7"-shaped support arm, arranging the top rod structure 1510 on the inner side of the main lifting arm 1200 can better enable the top rod structure 1510 to complete the emergency support operation.

[0075] In some embodiments, a cable drum protection frame 1600 is provided on the main lifting arm 1200 .

[0076] In this embodiment, adding the cable reel protection frame 1600 can improve the safety during the deployment process to a certain extent.

[0078] The above-mentioned protective bracket 1610 is mainly used to support the protective wheel 1620. After the protective bracket 1610 is unfolded into place, the protective wheel 1620 will be located above the roller mechanism 1300 and farther away from the rim of the cable reel 1800 than the roller mechanism 1300 to achieve the purpose of protection.

[0079] In some embodiments, reference Figures 1 to 3 The protective bracket 1610 is rotatably arranged on the main lifting arm 1200, and the rotation plane is parallel to the rotation plane of the main lifting arm 1200; a rotation adjustment limiter 1210 is provided on the main lifting arm 1200, and the rotation adjustment limiter 1210 is used to limit the protective bracket 1610 to different rotation angles.

[0080] The rotation adjustment limiter 1210 can adjust the rotation angle of the protective bracket 1610 , thereby allowing the protective bracket 1610 to better adapt to cable reels 1800 of different specifications.

[0081] In some embodiments, reference Figures 1 to 3 The rotation adjustment limit portion 1210 includes a plurality of first limit through holes provided on the main lifting arm 1200 , and the protective bracket 1610 is provided with at least one second limit through hole matching the first limit through hole.

[0082] The above-mentioned multiple first limiting holes can be arranged in a fan shape, and the geometric center of the fan can coincide with the rotation center of the rotation adjustment limiting part 1210. Then, the second limiting hole and any first limiting hole can be fixed by a pin to complete the adjustment of the rotation angle of the rotation adjustment limiting part 1210.

[0083] In some embodiments, reference Figures 1 to 2 The cable deployment assembly further includes a hoisting member 1220 disposed on the main lifting arm 1200 .

[0084] In this embodiment, considering that some transfer vehicles are relatively high and cannot be directly transferred using forklift equipment, the cable deployment assembly can be first lifted to the flat ground using the lifting parts 1220, and then the transfer can be completed by the forklift equipment.

[0085] In some embodiments, reference Figures 1 to 2 , the lifting part 1220 is set as a lifting ring.

[0086] In this embodiment, the lifting is achieved directly by using a lifting ring structure. The lifting ring structure is simple and easy to hang on the lifting equipment, and can adapt to the lifting needs in more scenarios.

[0089] In some embodiments, a handle 2600 is further provided on the top of the main frame 2100 .

[0090] In this embodiment, when the cable traction equipment for the cable channel is in a folded state, the overall structure is small and lightweight, and can be directly extracted using the handle 2600, making it easier for construction workers to transport the cable traction equipment for the cable channel from a smaller downhole channel.

[0092] The energy storage unit is used to provide power for the driving mechanism 2300 and can adopt products with high energy density and large energy storage capacity, such as lithium batteries.

[0093] The driver is powered by an energy storage unit and, under the control of the traction control system 2800, can drive the DC reduction motor to rotate, so that the DC reduction motor drives the first traveling mechanism 2110. It should be noted that the use of a DC reduction motor can provide greater driving force than an ordinary motor to achieve traction of the cable 1810.

[0094] In some embodiments, reference Figures 5 to 8 The main frame 2100 includes: The first base section 2120 has two first leg structures 2140 disposed at its bottom, with a space formed between the two first leg structures 2140 for the cable 1810 to pass through; the two first walking mechanisms 2110 are respectively disposed at the bottom of the two first leg structures 2140; One end of the second frame segment 2130 is connected to the first frame segment 2120, and the other end is hinged to the front support assembly 2400; the angle between the second frame segment 2130 and the first frame segment 2120 is an obtuse angle.

[0095] The first base frame segment 2120 and the second base frame segment 2130 may be integrally formed or welded.

[0096] The first base frame section 2120 comprises a main structure and two first leg structures 2140 disposed at the bottom of the main structure. The main structure can be used to house the energy storage unit and driver. The housing of the drive mechanism 2300 can be used to house a DC reduction motor corresponding to each first running mechanism 2110. The first running mechanisms 2110 can be mounted at the bottom of the two first leg structures 2140. It should be noted that if the first running mechanisms 2110 require steering capabilities, the steering mechanism can also be disposed on the first leg structures 2140 or the housing of the drive mechanism 2300.

[0097] The angle between the second frame segment 2130 and the first frame segment 2120 is set to be an obtuse angle, so that the traction control system 2800 can be set in the second frame segment 2130, so that when peripherals such as a display and a control panel need to be set, they can be set on the second frame segment 2130 for the operator to operate and view.

[0098] In some embodiments, reference Figure 5 、 6 , the cable pulling equipment for the cable channel also includes: The display and control unit 2700 is disposed on the second base frame section 2130 , and is electrically connected to the traction control system 2800 .

[0099] In this embodiment, the introduction of the display and control unit 2700 can facilitate the operator to adjust the setting parameters in the cable traction equipment for the cable channel and view the setting parameters, and can also realize the viewing of some operating parameters, such as: remaining power, mileage, continuous working time, etc.

[0100] The display control unit 2700 can be a product with both display and operation capabilities such as an LCD touch screen, or a combination of a display and a case. The specific forms are diverse and can be flexibly configured according to actual needs.

[0101] In some embodiments, the fixing assembly 2200 includes a fixing bracket having a plurality of fixing holes at different heights, each of which is used to fix the cable 1810 .

[0102] In this embodiment, providing a plurality of fixing holes at different heights can achieve adaptation to wiring devices of different heights and cables 1810 of different thicknesses, thereby improving the applicability of the cable pulling device for the cable channel.

[0103] In some embodiments, reference Figures 5 to 8 , the front end support assembly 2400 includes: The top of the rotating support structure 2420 is hinged to the top of the main frame 2100; the spacing adjustment bracket 2500 is arranged between the rotating support structure 2420 and the main frame 2100; The two second leg structures 2430 are respectively arranged on both sides of the bottom end of the rotating support structure 2420, and a space for the cable 1810 to pass through is formed between the two second leg structures 2430; the two second walking mechanisms 2410 are respectively arranged at the bottom of the two second leg structures 2430.

[0104] The above-mentioned rotating support structure 2420 can be composed of three connecting rods. For example, one end of two parallel connecting rods is hinged to one end of the second frame section 2130 away from the first walking mechanism 2110, and the third connecting rod is fixedly connected to the other end of the two parallel connecting rods, and the third connecting rod is arranged perpendicular to the two parallel connecting rods.

[0105] The second leg structure 2430 may be two support rods, the tops of the two support rods being arranged on the third connecting rod of the rotating support structure 2420 , and the bottoms thereof being respectively used to arrange the second walking mechanism 2410 .

[0106] In some embodiments, the spacing adjustment bracket 2500 comprises a telescoping bracket.

[0107] In this embodiment, the front end support assembly 2400 and the main body base 2100 can be folded and unfolded by directly using a telescopic bracket.

[0108] It should be noted that when using a retractable bracket, in order to ensure that the front support assembly 2400 and the main base frame 2100 have sufficient stability in the unfolded state, a retractable bracket with a certain damping can be used, or after unfolding, a limiting structure 1520 can be used to limit the extension and retraction of the retractable bracket.

[0109] In some embodiments, the retractable support comprises: A first support member, one end of which is connected to the main frame 2100; the first support member is provided with at least one first adjustment hole; The second support member has one end connected to the front support assembly 2400; the second support member is provided with at least one second adjustment hole; the first support member and the second support member are detachably connected via the first adjustment hole and the second adjustment hole.

[0110] In this embodiment, by providing a plurality of adjustment holes on the first support member and the second support member, after the main frame 2100 and the front support assembly 2400 are unfolded, the first support member and the second support member can be fixed directly using a limit assembly such as a latch to limit the rotation of the main frame 2100 and the front support assembly 2400. It will be understood that when multiple adjustment holes are provided, different rotation angles of the main frame 2100 and the front support assembly 2400 can be adjusted by fixing different adjustment holes.

[0111] In some embodiments, the first support member is configured as a tubular structure, and the second support member can extend into the first support member and slide along the first support member.

[0112] In this embodiment, the second support member is extended into the first support member, which can make the unfolding and folding operations of the main frame 2100 and the front support assembly 2400 more comfortable and also facilitate better fixation of the adjustment hole.

[0113] See also Figure 11 As shown, Figure 11 Flowchart of a wiring method provided in one embodiment of the present application, the wiring method is used to control the above-mentioned lightweight wiring system, including steps S100 to S900; S100: The four cable deployment assemblies are transferred to both sides of the cable drum 1800. The roller mechanisms 1300 of the two cable deployment assemblies on the same side abut against different sides of the same wheel rim of the cable drum 1800. The cable drum 1800 is pre-transferred to the plane where the cables are to be deployed. S200, controlling the telescopic devices 1400 in the four cable deployment assemblies to lift up so that the cable reel 1800 reaches a preset cable deployment height; S300, arranging a plurality of auxiliary wiring devices 3000 in a cable channel to be routed based on a pre-planned routing path, wherein the plurality of auxiliary wiring devices 3000 are at least used to implement rolling support for the cable 1810; S400, adjusting the spacing adjustment bracket 2500 to reduce the angle between the front support assembly 2400 and the main base frame 2100, so that the cable channel cable pulling device is in a folded state; S500, when the cable traction device for the cable channel is in a folded state, moving the cable traction device for the cable channel through the downhole channel to the cable channel to be wired; S600, in the cable channel to be routed, adjust the spacing adjustment bracket 2500 to increase the angle between the front support assembly 2400 and the main base frame 2100, so that the cable channel cable pulling device is in working condition; S700, adjusting the posture of the cable traction device for the cable channel so that the cable traction device for the cable channel is located on the wiring path; S800, connecting the cable 1810 to the fixing assembly 2200; S900 , controlling the driving mechanism 2300 to move so as to enable the two first walking mechanisms 2110 to move along the wiring path.

[0114] The cable deployment method in the embodiment of the present application can be applied to a control system in a portable wiring system.

[0115] The wiring method in the embodiment of the present application is implemented based on the above-mentioned lightweight wiring system. The lightweight wiring system has been described in detail above and will not be repeated here.

[0116] The above-mentioned cable deployment components, cable traction equipment for cable channels, and auxiliary wiring equipment 3000 can all be transported to the construction site via small transport vehicles.

[0117] The cable drum 1800 can also be transported to the site individually using a small vehicle, and then hoisted to the ground using a hoisting hoist or other small hoisting equipment.

[0118] After the above-mentioned four cable deployment assemblies are transported to the construction site by a small transport vehicle, the cable deployment assemblies are transferred to the location of the cable reel 1800 placed on the ground by a forklift equipment, and abutted against the rim of the cable reel 1800. It can be understood that the four cable reels 1800 will abut against the rims at different positions in different directions so as to subsequently complete the jacking operation of the cable reel 1800.

[0119] The above-mentioned control of the lifting of the telescopic devices 1400 in the four cable deployment assemblies can be completed by manually operating each cable deployment assembly individually, or by using an electronic control system to operate multiple cable deployment assemblies simultaneously.

[0120] The above-mentioned multiple auxiliary wiring devices 3000 can be arranged according to the wiring path. It should be noted that in order to protect the cable 1810 and the smooth pulling and deployment of the cable 1810, the auxiliary wiring devices 3000 will be arranged at the position where turning is required, for example, at the wellhead.

[0121] The above-mentioned adjustment of the spacing adjustment bracket 2500 to the folded state needs to be completed before the operator goes down the well, so that the operator can carry it to the wiring cable channel through the narrow downhole passage.

[0122] After the cable traction device for the cable channel is transported to the cable channel in a folded state, the spacing adjustment bracket 2500 can be operated to put it in an unfolded working state, and then the cable traction device for the cable channel can be controlled by a remote control device to move and move to the wiring path.

[0123] The above-mentioned cable traction equipment for the cable channel can move along the wiring path, and can make the two first walking mechanisms 2110 and the two second walking mechanisms 2410 always straddle the two sides of the auxiliary wiring equipment 3000 to complete the traction of the cable 1810. During traction, when the cable deployment component has no active cable deployment capability, it can passively deploy the cable under the action of the traction force. When the cable deployment component has the active cable deployment capability, it can cooperate with the travel speed of the cable traction equipment for the cable channel to achieve adaptive cable deployment.

[0124] In some embodiments, at least one cable deployment assembly further includes a drive device 1700 , which is disposed on the main lifting arm 1200 and is used to drive the roller mechanism 1300 to rotate; the drive device 1700 is wirelessly connected to the traction control system 2800 ; Controlling the action of the driving mechanism 2300 includes: Get walking control instructions, which include current walking direction and current walking speed; According to the walking control instruction, the driving mechanism 2300 is controlled to move so that the two first walking mechanisms 2110 move along the wiring path; Generate cable extension and retraction operation parameters according to the current walking speed; The cable deployment and retraction operation parameters are transmitted to the driving device 1700 , so that the driving device 1700 drives the cable drum 1800 to rotate according to the cable deployment and retraction operation parameters.

[0125] In this embodiment, considering that the cable deployment assembly can realize active cable deployment through the driving device 1700, the driving device 1700 can perform adaptive speed adjustment according to the current walking speed of the cable traction device driven by the driving mechanism 2300 to drive the cable channel to improve the cable deployment efficiency.

[0126] The above-mentioned travel control instructions can be determined by an operator operating a remote control device and wirelessly transmitted to the traction control system 2800.

[0127] The above cable deployment and retraction operation parameters can be understood as the cable deployment speed, which can be determined according to the current walking speed and the diameter of the cable drum 1800 currently deployed.

[0128] In some embodiments, at least one cable deployment assembly further includes a drive device 1700, which is disposed on the main lifting arm 1200 and is used to drive the roller mechanism 1300 to rotate. The portable cabling system further includes a cable deployment control system 1900 electrically connected to the drive device 1700, and the cable deployment control system 1900 is in communication with the traction control system 2800. Controlling the action of the driving mechanism 2300 includes: Get walking control instructions, which include current walking direction and current walking speed; According to the walking control instruction, the driving mechanism 2300 is controlled to move so that the two first walking mechanisms 2110 move along the wiring path; The current walking speed is transmitted to the cable deployment control system 1900, so that the cable deployment control system 1900 generates cable deployment and retraction operation parameters according to the current walking speed, and adjusts the working state of the driving device 1700 according to the obtained cable deployment and retraction operation parameters to drive the cable drum 1800 to rotate.

[0129] In this embodiment, the cable deployment assembly can achieve active cable deployment via drive device 1700 and is equipped with a cable deployment control system 1900. This allows cable deployment control system 1900 to generate cable deployment and retraction operating parameters based on the current travel speed and control drive device 1700 based on these operating parameters to adaptively adjust speed, thereby improving cable deployment efficiency. Furthermore, by separately controlling the cable deployment and traction functions, i.e., employing a dual control system, this effectively reduces the processing power requirements of a single control system, reduces the complexity of data processing within a single control system, and improves the stability of cable 1810 during installation.

[0130] In some embodiments, the cable traction device for the cable channel further includes a traction force detection unit 2810 electrically connected to the traction control system 2800 , the traction force detection unit 2810 being configured to detect traction force information of the cable traction device for the cable channel pulling the cable 1810 ; Generate cable extension and retraction operation parameters based on current travel speed, including: Obtaining traction force information collected by the traction force detection unit 2810; Determine initial operating parameters according to the current walking speed; The initial operating parameters are modified according to the traction force information to obtain the cable deployment and retraction operating parameters.

[0131] In this embodiment, the situation where the cable unwinding speed and the pulling speed do not match is further taken into consideration, and the specific situation of the mismatch is directly determined by detecting the traction force information of the cable 1810 pulled by the cable pulling equipment in the cable channel. Therefore, when there is a mismatch, the cable unwinding speed can be adaptively adjusted in time by adjusting the cable unwinding and retracting operating parameters of the driving device 1700.

[0132] The above-mentioned initial operating parameters can be understood as initial values ​​determined according to the current walking speed. For example, any current walking speed can correspond to an initial cable deployment speed, that is, the speed at which the driving device 1700 drives the roller mechanism 1300 to rotate.

[0133] The above traction force information can indicate the current traction state, that is, determine whether the traction force of the cable traction device for the cable channel increases or decreases. If it increases, it can be understood that the cable deployment speed is too slow, and if it decreases, it can be understood that the cable deployment speed is too fast.

[0134] The above correction of the initial operating parameters based on the traction information can be understood as follows: when the traction is increased, the speed of the roller mechanism 1300 driven by the drive device 1700 needs to be increased, and the more it is increased, the more it needs to be increased; when the traction is reduced, the speed of the roller mechanism 1300 driven by the drive device 1700 needs to be reduced, and the more it is reduced, the more it needs to be reduced.

[0135] In some embodiments, the portable cabling system further includes a posture detection unit 1910, which is disposed on the cable drum 1800 and is used to detect posture information of the cable drum 1800; the cable deployment control system 1900 is electrically connected to the posture detection unit 1910 and the four telescopic devices 1400; Control the lifting of the telescopic device 1400 in the four cable deployment assemblies, including: Obtaining posture information of the cable reel 1800 collected by the posture detection unit 1910; The four telescopic devices 1400 are controlled to extend based on the posture information. The four cable deployment assemblies are pre-transferred to both sides of a cable drum 1800. The roller mechanisms 1300 of the two cable deployment assemblies on the same side abut against different sides of the same wheel rim of the cable drum 1800. The cable drum 1800 is pre-transferred to the plane where the cables are to be deployed. When the cable drum 1800 reaches the preset cable deployment height and the posture information indicates that the tilt deviation of the cable drum 1800 in any direction is within the preset deviation parameter range, the four telescopic devices 1400 are controlled to stop extending and a leveling completion flag is generated.

[0136] The posture information of the cable reel 1800 collected by the posture detection unit 1910 can be directly detected using sensors such as tilt sensors and angle sensors, or it can be obtained by setting up multiple distance measuring sensors to detect the deviation of the wheel rims on both sides of the cable reel 1800 and then converting it.

[0137] The above-mentioned control of the extension of the four telescopic devices 1400 according to the posture information can be understood as directly determining the tilt state of the cable reel 1800 using the posture information. When tilt occurs in any direction, the telescopic speed of the telescopic device 1400 corresponding to the direction is appropriately adjusted to ensure that the cable reel 1800 always maintains a relatively horizontal state.

[0138] The height of the cable drum 1800 can be detected by a height sensor, or indirectly by detecting the extension distance of the telescopic device 1400, thereby determining whether the height of the cable drum 1800 reaches the preset cable deployment height.

[0139] The aforementioned preset deviation parameter ranges can include deviations in four directions: deviations in the direction corresponding to each cable deployment assembly, or deviations in the positive and negative directions along the central axis of the cable drum 1800, as well as the positive and negative directions perpendicular to the central axis and parallel to the horizontal plane. It will be appreciated that regardless of the direction determined, the corresponding cable deployment assembly ultimately needs to be adjusted accordingly.

[0140] The above posture information indicates that the tilt deviation of the cable reel 1800 is within the preset deviation parameter range, which can be understood as that the tilt angle of the cable reel 1800 determined according to the posture information is within the preset deviation parameter range in any of the four directions.

[0141] The above-mentioned preset deviation parameter range can be understood as a deviation angle of less than 0.5 degrees or 1 degree in any direction, and the specific size can be flexibly set according to actual requirements.

[0142] In some embodiments, the cable deployment control system 1900 generates cable deployment and retraction operation parameters according to the current travel speed, including: When the leveling completion flag is detected, in response to the cable deployment instruction, the working state of the driving device 1700 is adjusted according to the acquired cable deployment operation parameters to drive the cable drum 1800 to rotate.

[0143] In this embodiment, in order to improve the safety during the cable deployment, the cable deployment will not begin until the leveling completion mark is detected, so as to avoid the cable drum 1800 being deployed in a tilted state, resulting in accidents such as rollover.

[0144] The cable deployment and retraction instructions can be generated synchronously when the cable deployment and retraction operation parameters are generated according to the current travel speed. When the cable deployment assembly needs to be operated separately, the operator can also manually determine and generate the instructions when manually performing the cable deployment operation in the cable deployment control system 1900.

[0145] In some embodiments, controlling the extension of the four retractable devices 1400 according to the posture information includes: If the difference between the height of the cable drum 1800 and the preset cable deployment height is not within the fine adjustment range, and if the posture information indicates that the angle deviation between the corresponding direction of any cable deployment assembly and the horizontal plane exceeds the first preset angle tolerance range, the telescopic device 1400 in the corresponding cable deployment assembly is controlled to adjust its speed so that the angle deviation in the corresponding direction is within the first preset angle tolerance range; When the difference between the height of the cable reel 1800 and the preset cable deployment height is within the fine-tuning range, the posture information is obtained to determine the angular deviation between the corresponding direction of any cable deployment component and the horizontal plane, and when the angular deviation exceeds the second preset angle allowable range, the telescopic device 1400 is controlled to adjust with a preset step length so that the angular deviation in the corresponding direction is within the second preset angle allowable range, wherein the second preset angle allowable range is smaller than the first preset angle allowable range.

[0146] The above-mentioned fine-tuning range is used to enable the cable deployment control system 1900 to automatically adjust the leveling and lifting strategy. When the fine-tuning range is not reached, the leveling speed can be faster, that is, it can be adjusted at a faster speed. When the fine-tuning range is reached, it is necessary to focus on ensuring accuracy, that is, it can be adjusted at a lower speed or completed in a step-by-step manner.

[0147] The above-mentioned posture information indicates that the angle deviation between the corresponding direction of any cable deployment component and the horizontal plane exceeds the first preset angle tolerance range. It can be understood that the cable reel 1800 has a deviation, and the deviation is large and needs to be adjusted in time. However, it is still in the rapid adjustment stage at this time, and the extension speed of the telescopic device 1400 can be directly adjusted to complete it.

[0148] Specifically, when the angle of the cable reel 1800 is too low in the direction of any cable deployment component, the speed of the telescopic device 1400 is increased so that the angle deviation of the cable reel 1800 in that direction from the horizontal plane is within the first preset angle allowable range. When the angle of the cable reel 1800 in that direction is too high in the direction of any cable deployment component, the speed of the telescopic device 1400 is reduced so that the angle deviation of the cable reel 1800 in that direction from the horizontal plane is within the first preset angle allowable range. It can be understood that when the angle deviation of the cable reel 1800 in that direction is restored to the first preset angle allowable range, the speed of the corresponding telescopic device 1400 will be restored to the set speed to maintain a uniform speed with the other telescopic devices 1400, thereby continuing to achieve balanced lifting of the cable reel 1800.

[0149] The aforementioned control of the telescopic device 1400 for adjustment using a preset step length can be understood as nearly reaching the preset cable deployment height, but requiring precision adjustment in a stepwise manner to mitigate the lack of leveling accuracy caused by rapid adjustment. It can be understood that reaching the precision adjustment range can be understood as completing the height adjustment, at which point high-precision leveling is required. In this case, for tilted directions, the telescopic device 1400 can be controlled in a stepwise manner to complete the adjustment. The step length can be adjusted according to actual needs, for example, the step distance can be controlled to be 0.5mm, 1mm, etc.

[0150] Specifically, the aforementioned step-by-step adjustment control of the telescopic mechanism 1400 is a key step in ensuring precision during the adjustment of the equipment's cable reel 1800. This step-by-step adjustment mode employs a small-step, high-frequency adjustment strategy. Displacement sensors monitor the extension of the telescopic mechanism 1400 in real time, enabling precise calibration of the equipment's height with sub-millimeter single displacements.

[0151] Furthermore, when the height error of the equipment enters the precision adjustment range, the height adjustment phase is considered complete. At this point, the system's focus shifts to high-precision leveling. The posture detection unit 1910 (e.g., a three-dimensional tilt sensor) continuously collects the posture information of the cable drum 1800. Once tilt is detected, the cable deployment control system 1900 quickly locates the tilt direction and angle. For any deviation in the direction, the telescopic device 1400 in the corresponding direction will make compensatory adjustments in a pulsed stepping manner. This fine-tuning method can effectively overcome the lack of precision caused by inertial impact and hydraulic lag during rapid adjustment, making height adjustment more stable and precise.

[0152] In some embodiments, the setting of the above-mentioned step length may not be fixed, but may follow the principle of dynamic adjustment. When the initial error is large (such as exceeding ±2mm), a step length of 1mm can be selected to correct the obvious deviation at a faster speed; as the error gradually narrows to within ±1mm, the step length automatically switches to 0.5mm for more precise calibration; in special operating scenarios with extremely high precision requirements, even a micro-step of 0.1mm can be enabled to ensure that the posture adjustment accuracy of the cable reel 1800 is within ±0.1°. Through this hierarchical adjustment strategy, both the leveling efficiency can be guaranteed and the sub-millimeter height control accuracy can be achieved, so that the horizontality, verticality and other indicators of the cable reel 1800 fully meet the strict engineering standards, providing a stable and reliable foundation for the subsequent cable 1810 deployment operation.

[0153] The first preset angle allowable range is larger than the angle range in the aforementioned preset deviation parameter range. For example, when the preset deviation parameter range stipulates that the angle deviation needs to be less than 0.5 degrees, the first preset angle allowable range stipulates that the angle deviation is less than 1 degree.

[0154] The above-mentioned second preset angle allowable range can be understood as a preset deviation parameter range, and the deviation angle constrained by the second preset angle allowable range can also be smaller than the preset deviation parameter range. For example, when the second preset angle allowable range stipulates that the angle deviation needs to be less than 0.4 degrees, the preset deviation parameter range stipulates that the angle deviation needs to be less than 0.5 degrees.

[0155] In some embodiments, the telescopic device 1400 includes: a lifting cylinder 1410, a hydraulic drive system 1420, and a pressure detection unit; one end of the lifting cylinder 1410 is rotatably mounted on the base 1100, and the other end is rotatably connected to the main lifting arm 1200, with the rotation plane of the lifting cylinder 1410 being parallel to the rotation plane of the main lifting arm 1200; the hydraulic drive system 1420 is mounted on the base 1100 and is used to drive the lifting cylinder 1410 to extend and retract; the pressure detection unit is connected to the cable deployment control system 1900 and is used to detect the pressure of the lifting cylinder 1410; Before generating the leveling completion mark, the cable 1810 deployment method further includes: The oil pressures of the four lifting cylinders 1410 are adjusted so that the pressure differences among the four lifting cylinders 1410 are all within the allowable pressure difference range.

[0156] In this embodiment, considering that the four hydraulic cylinders may have a large pressure deviation after leveling, in order to make the hydraulic deviation pressure within the allowable range, a hydraulic leveling process can be added.

[0157] The above-mentioned hydraulic leveling process can be performed in the stage of leveling in a step-by-step manner. By repeatedly performing hydraulic leveling and leveling the posture of the cable reel 1800, the posture of the cable reel 1800 can eventually meet the leveling requirements and the oil pressure of the four lifting cylinders 1410 can meet the leveling requirements.

[0158] Specifically, the above-mentioned hydraulic leveling process is mainly used in the step-by-step leveling stage, and a cyclic iterative control strategy is used to achieve precise leveling. The system collects the posture data of the cable drum 1800 in real time at a preset sampling period, and combines the feedback values ​​of the pressure detection units of the four lifting cylinders 1410 to build a dynamic leveling control model. Each leveling cycle includes two core steps: first, the cable deployment control system 1900 independently adjusts the extension and contraction of each lifting cylinder 1410 so that the tilt angle of the cable drum 1800 gradually converges to the set threshold; then, the data of the posture detection unit 1910 is used to perform a secondary calibration on the cable drum 1800 to correct minor deviations caused by mechanical clearance or uneven load distribution. This dual closed-loop control mechanism, through multiple iterations, ultimately achieves a dual balance between the posture of the cable drum 1800 and the oil pressure of the four lifting cylinders 1410.

[0159] It should be noted that in actual operation, the operator will try to choose an area with a flat ground and choose the same model of cable deployment components, so that the height of multiple cable deployment components lifted to the rim can be as consistent as possible. In this case, after the cable reel 1800 is leveled, the actual deviation of the oil pressure of the four lifting cylinders 1410 is small. Usually, after a few adjustments, the oil pressure can be leveled while taking into account the leveling of the cable reel 1800.

[0160] Specifically, in actual engineering applications, operators will give priority to working areas with uniform foundation hardness and flatness that meet standards, and reduce the impact of environmental factors on leveling accuracy through site pretreatment. At the same time, cable deployment components of the same model and specifications are strictly selected to ensure the consistency of the mechanical parameters of each component. This pre-control measure significantly improves the leveling efficiency. When multiple cable deployment components are lifted synchronously, the wheel rim height deviation can be controlled within a lower range. When hydraulic leveling is performed on this basis, the initial oil pressure difference of the four lifting cylinders 1410 is usually small. Usually, after 3 to 5 iterative adjustments, the engineering standards for posture leveling and hydraulic leveling can be met, which greatly shortens the leveling time and reduces the system energy consumption.
