Description

Technical Field

[0001] The present invention relates to the field of cable laying, and particularly to a cable laying method and a cable laying device. Background Art

[0002] In the existing cable trenching and laying projects, multiple processes and devices are often used step by step. That is, a trencher is first used to dig a trench, then the cable is buried, and finally backfilling and ground restoration are carried out. That is, the existing method for cable construction and laying is: fixing the cable reel on a bracket and relying on manual traction to lay the cable, and burying the cable in a pre-dug underground trench.

[0003] The problems existing in this method are as follows: 1. The coordination between manual labor and the tractor is not harmonious, which easily damages the cable and results in low laying efficiency. When laying multiple cables simultaneously, it is very difficult for the existing cable laying machine to synchronously and coordinately operate in a manual manner, and it consumes manpower and increases costs; 2. This method is only suitable for cable reels with small tonnage in urban environments; 3. The manual method cannot achieve the installation and unwinding of large-weight reels, and the labor intensity of workers is high.

[0004] In summary, there is an urgent need for a cable laying method and a cable laying device to solve the problems of high labor intensity in reel installation and low efficiency of manual unwinding in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide a cable laying method and a cable laying device to solve the problems of high labor intensity in reel installation and low efficiency of manual unwinding in the prior art. The specific technical solutions are as follows:

[0023] A cable releasing device for implementing the above cable releasing method, the cable releasing device includes a traveling assembly and a working arm assembly;

[0024] The walking assembly is used for walking; the working arm assembly includes a swing arm, a lifting arm, a first telescopic member, and a second telescopic member; the swing arm is hinged to the walking assembly; one end of the lifting arm is hinged to the swing arm, and the other end is rotatably connected to the reel to be unreeled; both ends of the first telescopic member are respectively hinged to the swing arm and the walking assembly; both ends of the second telescopic member are respectively hinged to the swing arm and the lifting arm.

[0025] Preferably, in the above technical solution, a support seat for supporting on the ground is hinged to one end of the swing arm; the support seat is provided with spike teeth facing the ground.

[0026] Preferably, in the above technical solution, a limit switch for controlling the swinging state of the swing arm is further included; the limit switch is connected to the first telescopic member.

[0027] Preferably, in the above technical solution, the other end of the lifting arm is connected to the reel through a tooth pin assembly; the tooth pin assembly includes a pay-off disc, a mounting shaft, and a positioning pin shaft; one end of the mounting shaft is arranged at the other end of the lifting arm; the mounting shaft coaxially penetrates through the pay-off disc, and the other end of the mounting shaft is arranged in the central hole of the reel; the pay-off disc is fixed to the reel through the positioning pin shaft.

[0028] Preferably, in the above technical solution, a driving pay-off component is further included; the driving pay-off component includes a welding pin shaft, a gear, and a driving member; a plurality of groups of welding pin shafts are arranged on the pay-off disc along the circumferential direction of the pay-off disc, and a gap meshing with the gear is formed between two adjacent groups of welding pin shafts; the driving member is arranged on the lifting arm, and the output end of the driving member is connected to the gear.

[0029] Applying the technical solution of the present invention has the following beneficial effects:

[0030] (1) The cable unreeling method in the present invention includes step S1 and step S2. In step S1, through the multi-degree-of-freedom swinging of the working arm assembly, the reel to be unreeled is lifted onto the cable unreeling device, which can reduce the labor intensity and adapt to the working conditions of large-weight construction. And the cable is unreeled by driving the reel to walk through the cable unreeling device, avoiding the problems brought by the cooperation between manual labor and the tractor, etc., and can greatly improve the cable laying efficiency.

[0031] (2) The cable unreeling device of the present invention includes a traveling assembly and a working arm assembly. The working arm assembly includes a swing arm, a lifting arm, a first telescopic member, and a second telescopic member. In the present invention, the traveling assembly is used for traveling and driving the reel to unreel. The first telescopic member drives the swing arm to swing to one side of the reel. The second telescopic member drives the other end of the lifting arm to correspond to the reel. After the reel is assembled on the other end of the lifting arm, the swing arm and the lifting arm are combined to install the heavy reel on the traveling assembly, making the loading and unloading of the reel simple, labor-saving, and convenient. It can achieve long-distance transportation and unreel as the traveling assembly moves forward. That is, in the present invention, the multi-degree-of-freedom swing is realized by setting the swing arm and the lifting arm, avoiding the problems of complicated reel installation and high labor intensity.

[0032] (3) The support base of the present invention can make the device better adapt to the ground flatness. The bottom panel of the support base is designed with nail teeth to ensure that the support base is more stable and firmly attached to the ground when installing the cable reel. On the other hand, during the lifting process of the reel, the support base supports the ground, further ensuring the stability of the overall structure and preventing the occurrence of tipping.

[0033] (4) In the present invention, a support shaft is arranged at the top position of the swing arm. After the lifting arm lifts the cable reel above the traveling assembly, the reserved card slot on the lifting arm is stuck on the support shaft, transferring the main force to the entire working arm assembly and the traveling assembly, avoiding deformation of the lifting arm due to separate force.

[0034] (5) In the present invention, after the second telescopic member lifts the reel, the first telescopic member retracts. When the swing arm returns to its position, the limit switch also correspondingly controls the first telescopic member to stop working, with good coordination.

[0035] (6) In the present invention, when the traveling assembly is loaded with heavy objects, going uphill and downhill easily causes the vehicle body to shake, resulting in low driving stability. Therefore, a leg assembly is designed under the traveling assembly. The rollers on the legs can intervene in supporting the ground in advance to buffer the large shake of the vehicle body. That is, during driving, by adjusting the telescopic length of the third telescopic member, the rollers on the legs are driven to contact the ground to play a stable supporting role. When climbing a slope, the rollers on the legs extend in advance to prevent the front of the vehicle from shaking, and when going downhill, it prevents the center of gravity from moving forward and causing the vehicle to overturn.

[0036] (7) In the present invention, a part of the structure of the mounting shaft is located in the central hole of the reel, that is, a short shaft connection structure is adopted to replace the existing through-shaft connection method, which can reduce the weight, lower the labor intensity of reel installation, and simplify the installation work. The unreeling disc is connected to the reel through a positioning pin shaft to ensure the stability of the reel and facilitate unreeling.

[0037] (8) In the present invention, the wear of the mounting shaft is reduced by setting a shaft sleeve and a rotating sleeve.

[0038] (9) In the present invention, the driving member drives the gear to rotate, and the gear drives the welding pin shaft and the unwinding reel to rotate, thereby realizing unwinding. The cooperation form between the gear and the welding pin shaft is more stable and has strong reliability.

[0039] (10) In the present invention, the disassembly component is mainly used for disassembling the mounting shaft, saving the disassembly and assembly time of the mounting shaft and reducing the labor intensity.

[0040] (11) In the present invention, the platform can be horizontally pulled out through the sliding groove, which is convenient and saves space; when the device is moving, the pull rod is disassembled and the stairs are fixed inside to save space.

[0041] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The following will refer to the drawings for a further detailed description of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0058] Embodiment:

[0059] This embodiment discloses a cable laying method and a cable laying device. The cable laying method in this embodiment needs to use the cable laying device in this embodiment. First, the cable laying device in this embodiment will be described as follows:

[0060] A cable laying device includes a traveling assembly 1, a working arm assembly 2, a leg assembly 4, a tooth pin assembly component 5, a driving pay-off component 6 and a disassembly component 7, as Figures 1 to 10 shown, specifically as follows:

[0061] As Figure 1 and Figure 2As shown in the figure, the walking assembly 1 includes a crawler walking mechanism 1.1, a frame structure 1.2, a cab 1.3, a walkway 1.4, a staircase 1.5, and a pull rod 1.6;

[0062] Compared with an automobile chassis, the crawler walking mechanism 1.1 has good passability, is suitable for complex geological conditions and road conditions, has a lower center of gravity, and better anti-tipping performance. The crawler walking mechanism 1.1 refers to the existing structure.

[0063] The frame structure 1.2 is fixed above the crawler walking mechanism 1.1, and the frame structure 1.2 can serve as a carrier for various components;

[0064] The cab 1.3 is arranged in front of the frame structure 1.2; the walkway 1.4 is horizontally slidably arranged on the frame structure 1.2. Specifically, it is preferably that the walkway 1.4 is slidably arranged on the frame structure 1.2 through a chute, so that the walkway 1.4 can be pulled out outside the cab 1.3 or retracted into the frame structure 1.2 in the horizontal direction; the walkway 1.4 corresponds to the door on the cab 1.3, facilitating pedestrians to pass through the walkway 1.4; one end of the staircase 1.5 is hinged to the frame structure 1.2, the other end of the staircase 1.5 is detachably connected to one end of the pull rod 1.6, and the other end of the pull rod 1.6 is detachably connected to the frame structure 1.2. The staircase 1.5 and the walkway 1.4 can form a pedestrian passage for easy getting on and off the vehicle; when the device is walking, the pull rod 1.6 is disassembled and the staircase 1.5 is fixed inside the frame structure 1.2.

[0065] As Figure 5 shown, the outrigger assembly 4 includes outriggers 4.1, rollers 4.2, and a third telescopic member 4.3; one end of the outrigger 4.1 is hinged below the frame structure 1.2 of the walking assembly 1, and a roller 4.2 is arranged (preferably rotatably arranged) at the other end of the outrigger 4.1; both ends of the third telescopic member 4.3 (such as a telescopic oil cylinder) are respectively hinged to the outrigger 4.1 and the frame structure 1.2; when the third telescopic member 4.3 extends, the outer circumferential surface of the roller 4.2 can be in rolling contact with the ground to play a supporting role. In this embodiment, preferably, a plurality of sets of protrusions are arranged on the outer circumferential surface of the roller 4.2 to enhance the stability after contacting the ground. In this embodiment, outrigger assemblies 4 are arranged on both the left and right sides below the frame structure 1.2.

[0066] The working arm assembly 2 includes a swing arm 2.1, a lifting arm 2.2, a first telescopic member 2.3, and a second telescopic member 2.4; both the first telescopic member 2.3 and the second telescopic member 2.4 are telescopic oil cylinders. As Figure 1 and Figure 3 shown, specifically as follows:

[0067] The horizontal side view shape of the swing arm 2.1 is V-shaped, and the corner position of the V-shape is hinged to the tail end of the frame structure 1.2; both ends of the first telescopic member 2.3 are respectively hinged to the swing arm 2.1 and the frame structure 1.2. In this embodiment, preferably, a support seat 2.11 is hinged to the end of the swing arm 2.1 away from the cab 1.3. The support seat 2.11 can support on the ground when installing the winding drum 8. Preferably, spike teeth are provided on the side of the support seat 2.11 facing the ground. In this embodiment, the number of the first telescopic members 2.3 is set to two groups, and the two groups of the first telescopic members 2.3 are respectively arranged corresponding to the two sub-arms of the swing arm 2.1.

[0068] One end of the lifting arm 2.2 is hinged to the middle position of the swing arm 2.1, and the other end of the lifting arm 2.2 is used to connect the winding drum 8. Specifically, the other end of the lifting arm 2.2 is connected to the winding drum 8 through the tooth pin assembly component 5; a reinforcing shaft 2.2a (as Figure 3 shown) is fixedly arranged between the two side sub-arms of the lifting arm 2.2, which can ensure the structural strength of the lifting arm 2.2.

[0069] One end of the second telescopic member 2.4 is hinged to the end of the swing arm 2.1 away from the cab 1.3 (or the support seat 2.11), and the other end of the second telescopic member 2.4 is hinged to the end of the lifting arm 2.2 close to the winding drum 8.

[0070] Preferably, as Figure 6 and Figure 7 shown, a support shaft 2.1a for supporting the lifting arm 2.2 is fixedly arranged on the swing arm 2.1, and a semi-circular clamping groove 2.2b cooperating with the support shaft 2.1a is arranged on the lifting arm 2.2. After the winding drum 8 is installed above the frame structure 1.2 under the drive of the working arm assembly 2, the clamping groove 2.2b is clamped on the outer periphery of the support shaft 2.1a, and the gravity of the winding drum 8 is transmitted to the entire working arm assembly 2 and the frame structure 1.2, avoiding deformation of the lifting arm 2.2 due to separate force.

[0071] As Figure 7As shown, after the winding drum 8 (i.e., the cable winding drum) is installed at the other end of the lifting arm 2.2, the first telescopic member 2.3 retracts, causing the swing arm 2.1 to start swinging back to above the frame structure 1.2. When the swing arm 2.1 returns to its initial position on the frame structure 1.2, the limit switch 3 operates and controls the first telescopic member 2.3 to stop operating, specifically as follows: The limit switch 3 is installed at the intersection of the swing arm 2.1 and the frame structure 1.2. After the swing arm 2.1 swings into place and contacts the limit switch 3, the first telescopic member 2.3 stops operating. That is, when the limit rod 3.a on the swing arm 2.1 contacts the limit switch 3 on the frame structure 1.2, the limit rod 3.a toggles the limit switch 3, and the first telescopic member 2.3 stops working (preferably, the limit switch 3 is electrically connected to the first telescopic member 2.3). Of course, in this embodiment, in order to achieve the limit control of the swing arm 2.1, other existing limit control methods can also be referred to.

[0072] As Figure 8 and Figure 9 shown, the pin and gear assembly 5 includes a unwind reel 5.1, a mounting shaft 5.2, a positioning pin 5.3, a bushing 5.4, and a rotating sleeve 5.5.

[0073] A mating hole is provided at the other end of the lifting arm 2.2. One end of the mounting shaft 5.2 (the mounting shaft is a short shaft, that is, the axial length of the mounting shaft is equal to 1 / 8 to 1 / 5 of the axial width of the winding drum) is coaxially arranged in the mating hole. The bushing 5.4 is coaxially sleeved on the outer periphery of the mounting shaft 5.2, and the bushing 5.4 is located within the mating hole, that is, the bushing 5.4 is installed between the inner circumference of the mating hole and the outer circumference of the mounting shaft 5.2. The mounting shaft 5.2 axially penetrates through the unwind reel 5.1 (circular), specifically, the mounting shaft 5.2 is coaxially arranged with the unwind reel 5.1, and the unwind reel 5.1 and the bushing 5.4 are fixed together by fasteners. The unwind reel 5.1 and the winding drum 8 to be installed are connected and fixed by the positioning pin 5.3. The rotating sleeve 5.5 is arranged at the end of the mounting shaft 5.2 away from the lifting arm 2.2. The rotating sleeve 5.5 is specifically fixed to the mounting shaft 5.2 by fasteners. When installing the winding drum 8, the end of the mounting shaft 5.2 with the rotating sleeve 5.5 is coaxially inserted into the central hole 8.a of the winding drum. Among them, the outer diameter of the rotating sleeve 5.5 matches the inner diameter of the central hole 8.a of the winding drum.

[0074] Preferably, the pin and gear assembly 5 further includes an end cap 5.6 and a top cover 5.7. The end cap 5.6 is coaxially arranged on the end face of the mounting shaft 5.2, and the top cover 5.7 is coaxially arranged on the end face of the bushing 5.4.

[0075] As Figure 4As shown in the figure, the driving unwinding assembly 6 includes a welding pin shaft 6.1, a gear 6.2, and a driving member 6.3 (such as a motor or a speed reducer); a plurality of groups of the welding pin shafts 6.1 are arranged on the unwinding disc 5.1 along the circumferential direction of the unwinding disc 5.1, and a gap for meshing with the gear 6.2 is formed between two circumferentially adjacent groups of the welding pin shafts 6.1; the gear 6.2 is rotatably arranged at the end of the lifting arm 2.2 away from the support base 2.11; the output end of the driving member 6.3 is fixedly connected to the gear 6.2, and the driving member 6.3 drives the gear 6.2 to rotate, so that the gear 6.2 meshes with a plurality of groups of the welding pin shafts 6.1, and further drives the unwinding disc 5.1 and the winding drum 8 to rotate. In this embodiment, the welding pin shaft 6.1 is fixed on the unwinding disc 5.1 by a split pin.

[0076] As Figure 9 and Figure 10 As shown in the figure, the disassembly assembly 7 is used to disassemble the mounting shaft 5.2 of the tooth pin assembly 5 from the lifting arm 2.2; the disassembly assembly 7 includes a support frame 7.1, an anti-threaded sleeve 7.2, and a pin pulling rod 7.3; the support frame 7.1 adopts a gantry structure, and the support frame 7.1 is fixed on the lifting arm 2.2 by fasteners; an internal threaded hole for cooperating with the anti-threaded sleeve 7.2 is provided on the support frame 7.1; one end of the pin pulling rod 7.3 is movably connected to the anti-threaded sleeve 7.2;

[0077] The connection relationship between one end of the pin pulling rod 7.3 and the anti-threaded sleeve 7.2 is specifically as follows: a piston part 7.31 is provided at one end (i.e., the upper end) of the pin pulling rod 7.3, the piston part is located inside the anti-threaded sleeve 7.2, and the specification of the piston part is larger than the lower end opening of the anti-threaded sleeve 7.2. In this way, the pin pulling rod 7.3 and the anti-threaded sleeve 7.2 cannot be axially separated, so that when the anti-threaded sleeve 7.2 moves upward, it can drive the pin pulling rod 7.3 to move upward to pull out the mounting shaft 5.2; and the pin pulling rod 7.3 and the anti-threaded sleeve 7.2 can also rotate relatively to avoid the external thread of the anti-threaded sleeve 7.2 interfering with the threaded connection between the pin pulling rod 7.3 and the mounting shaft 5.2; and axially (the axial direction of the pin pulling rod), the pin pulling rod 7.3 and the anti-threaded sleeve 7.2 can relatively slide, which is convenient for the pin pulling rod 7.3 to have a certain downward movement space when being threadedly connected to the mounting shaft 5.2;

[0078] In this embodiment, the other end (i.e., the lower end) of the pin pulling rod 7.3 is used for threaded connection with the mounting shaft 5.2 (i.e., a threaded hole for connecting with the pin pulling rod 7.3 is provided on the mounting shaft 5.2), and by rotating the anti-threaded sleeve 7.2, the pin pulling rod 7.3 is driven to move along its axial direction, so as to pull out the mounting shaft 5.2.

[0079] Among them, the thread engagement relationship is as follows: the thread on the outer circumference of the reverse-thread sleeve 7.2 has the same helix direction as the thread of the internal thread hole on the support frame 7.1, while the internal thread hole of the support frame 7.1 has a helix direction opposite to that of the thread at the head of the pin-pulling rod 7.3 (i.e., the end for connecting to the mounting shaft 5.2).

[0080] During the pulling-out operation, first remove the end cover 5.6 on the mounting shaft 5.2. Align the pin-pulling rod 7.3 with the thread hole on the mounting shaft 5.2, rotate the pin-pulling rod 7.3 clockwise, and after the pin-pulling rod 7.3 is tightened with the thread hole on the mounting shaft 5.2, then rotate the reverse-thread sleeve 7.2 counterclockwise so that the reverse-thread sleeve 7.2 can drive the pin-pulling rod 7.3 and the mounting shaft 5.2 to move upward, thereby pulling out the mounting shaft 5.2.

[0081] In this embodiment, as Figure 1 and Figure 3 shown, both the lifting arm 2.2 and the swing arm 2.1 are provided with two left and right sub-arms, and tooth pin assembly components 5, driving unwinding components 6, and disassembly components 7 are respectively arranged on the two left and right sub-arms in a matching manner. The tooth pin assembly components 5 on the two sub-arms of the lifting arm 2.2 can be respectively connected to the central holes at both ends of the cable reel 8.

[0082] In addition, the cable-laying device in this embodiment further includes the following structures:

[0083] Electric control cabinet 9: The electric control cabinet 9 is installed on the vehicle frame structure 1.2, specifically located behind the cab 1.3. The electric control cabinet 9 is the power supply and control center of the electrical system, and is internally configured with electrical components such as a controller module, terminal blocks, and intermediate relays to achieve the distribution of the power supply for the whole machine, and to control the walking of the equipment and the operation of the cable reel 8 and the hardware emergency stop through the power supply of the control cabinet, so as to achieve the control of the walking of the equipment and the operation of the cable reel 8, and to collect data such as fuel level and hydraulic oil temperature.

[0084] Electric control button box 10: In this embodiment, the electric control button box 10 is installed on the vehicle frame structure 1.2, specifically located at one end close to the swing arm 2.1. When the operator controls the first telescopic member 2.3 and the second telescopic member 2.4 through the electric control button box 10, it is convenient to directly observe the installation and lifting state of the cable reel 8, so as to observe in real time whether the lifting of the cable reel 8 is stable and in place. On the other hand, when a failure occurs in the remote control mode, local operation can still be carried out, that is, the electric control button box 10 can control the operation of the driving member 6.3, the first telescopic member 2.3, and the second telescopic member 2.4.

[0085] High-definition cameras and lighting lamps; the high-definition cameras and lighting lamps are arranged circumferentially around the cable laying device, that is, multiple groups of high-definition cameras and lighting lamps are arranged along the horizontal circumference. The high-definition cameras and lighting lamps are used to observe the blind spot conditions and the night operations of on-site personnel. In this embodiment, preferably, 4 high-definition cameras are arranged around the device, and 1 high-definition camera is arranged in front of the frame structure 1.2 to observe the road conditions ahead during the driving process.

[0087] The cable laying method in this embodiment is as follows:

[0088] The cable laying method includes steps S1 to S3, as Figure 12 shown, specifically as follows:

[0089] Before performing step S1, according to the length of the cable to be laid, a cable trench is dug on the ground, and the cable reels to be unreeled are stacked neatly at the initial position of the cable trench.

[0090] Step S1: Install the reel 8 to be unreeled on the working arm assembly 2 of the cable laying device, as Figure 11 shown, and the installation process is as follows:

[0091] Step S1.1: The first telescopic member 2.3 extends. When one end of the swing arm 2.1 supports on the ground, the first telescopic member 2.3 stops operating. In this step, preferably, after the support seat 2.11 on one end of the swing arm 2.1 supports on the ground, the first telescopic member 2.3 stops operating.

[0092] Step S1.2: The second telescopic member 2.4 shortens, causing the lifting arm 2.2 to swing downward. When the end of the lifting arm 2.2 away from the swing arm 2.1 (i.e., the end with the pin assembly component 5) aligns (roughly aligns) with the central hole 8.a of the cable reel 8, the second telescopic member 2.4 stops operating;

[0093] Step S1.3: Install the cable reel 8 on the end of the lifting arm 2.2 away from the swing arm 2.1. In this step, the cable reel 8 is specifically installed on the lifting arm 2.2 through the pin assembly component 5. The installation process is as follows:

[0094] Step S1.31: Rotationally install the unwinding disc 5.1 on the lifting arm 2.2. Specifically in this step, a mating hole is provided at the other end of the lifting arm 2.2, and a bushing 5.4 is rotatably installed coaxially within the mating hole. The unwinding disc 5.1 is fixed to the bushing 5.4 within the mating hole, enabling the unwinding disc 5.1 to rotate;

[0095] Step S1.32: With the aid of a jack, after adjusting the central hole 8.a of the reel to be coaxially corresponding to the unwinding disc 5.1 (specifically, the central hole of the unwinding disc), fix the unwinding disc 5.1 and the reel together with a positioning pin shaft 5.3;

[0096] Step S1.32: Insert the installation shaft coaxially through the bushing 5.4 and the unwinding disc 5.1, and insert one end of the installation shaft (i.e., the end with the rotating sleeve 5.5), together with the rotating sleeve 5.5, coaxially into the central hole 8.a of the reel. At this point, the installation of the reel 8 on the pin assembly component 5 is completed;

[0097] Step S1.4: The second telescopic member 2.4 extends, lifting the cable reel 8 above the ground to the highest position, and then the second telescopic member 2.4 stops operating;

[0098] Step S1.5: The first telescopic member 2.3 shortens, driving the swing arm 2.1 and the cable reel 8 to swing back to the vehicle frame structure 1.2. In this step, preferably, when the limit rod 3.a on the swing arm 2.1 actuates the limit switch 3 on the vehicle frame structure 1.2, the second telescopic member 2.4 stops operating;

[0099] Step S2: The traveling assembly of the cable laying device travels along the cable laying direction. Meanwhile, the driving unwinding assembly 6 drives the unwinding disc 5.1 and the reel 8 to rotate, thereby achieving cable laying. In this step, the driving unwinding assembly 6 drives the unwinding disc to rotate as follows: The driving member 6.3 drives the gear 6.2 to rotate, causing the gear 6.2 to mesh with multiple groups of welded pin shafts 6.1, and then driving the unwinding disc 5.1 and the reel 8 to rotate;

[0100] Step S3: After completing the cable laying operation for the specified number of kilometers, use an excavator to backfill the cable trench;

[0101] Repeat the above steps S1 to S3 until the laying work is completed.

[0102] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
