Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to an adjustable cable conduit multi-reinforcement laying device and a use method thereof. Background Art

[0002] During the cable construction process, it is often necessary to feed the cable into an underground pipeline or lay it in a cable trench. At present, in the cable laying process, a cable laying device is generally used to assist. When the cable needs to be laid along a corner path, a corner guide mechanism is generally set at the corner to play an auxiliary support and guiding role, so that the cable can pass through the corner smoothly, reducing friction and damage. In order to improve the smoothness of cable laying, the existing corner guide mechanism also adds additional power to drive the cable forward. However, the existing cable laying device has the following problems: for long-distance and multi-corner laying routes, due to installation errors and construction factors, the cable between adjacent corners will be twisted during the traction laying process, resulting in the cable itself generating twisting and deformation stress, which still affects the smoothness of laying and even causes damage to the cable during the laying process; and the existing corner guide mechanism is difficult to adjust the guidance according to the size of the corner and has poor adaptability. Summary of the Invention

[0003] The purpose of the present invention is to provide an adjustable cable duct multi-reinforcement laying device and a method of use to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The present invention provides an adjustable cable duct multi-reinforcement laying device, comprising:

[0006] A plurality of corner guide mechanisms are provided, and the plurality of corner guide mechanisms are sequentially arranged along the cable laying path. The corner guide mechanism includes two rotating frames, two power-assisted guide assemblies, and main wheels. One end of the two rotating frames is hinged with an adjustable angle, and one power-assisted guide assembly is installed at each other end. The main wheels are arranged at the hinge between the two rotating frames, and the main wheels are used to contact the outer periphery of the cable. The power-assisted guide assembly includes two guide pulleys and a power-assisted drive structure. The two guide pulleys are arranged in parallel at an interval to form a guide gap for the cable to pass through. The power-assisted drive structure is used to drive at least one of the guide pulleys to rotate, so as to drive the cable to be transported forward along the axial direction of the cable.

[0007] There is at least one twist correction mechanism, and at least one twist correction mechanism is arranged between each two adjacent corner guide mechanisms. The twist correction mechanism includes a clamping component and a torsion drive component. The clamping component has a clamping state for clamping the cable and a loosening state for loosening the cable. When the clamping component is in the clamping state, the cable and the clamping component can be relatively slidably arranged along the axial direction of the cable, and are relatively fixed along the circumference of the cable. The torsion drive component is used to drive the clamping component in the clamping state to rotate around the axis of the cable to drive the cable to twist and rotate.

[0008] The cable conduit multiple reinforcement laying device of the present invention has the following beneficial effects:

[0009] During use, multiple corner guide mechanisms are installed at different corners according to the cable laying path, and the angle between each pair of rotating frames is adjusted according to the angles at each corner to adapt to various cable turning and laying scenarios. The cables to be laid are passed through multiple power-assisted guide assemblies, multiple main wheels and clamping assemblies. The main wheels guide and turn the cables to reduce the friction of the cables at the turning nodes, so that the cables pass through the turning positions under lower tension. A twist correction mechanism is installed between two adjacent corner guide mechanisms. During laying, the cables to be laid are passed through multiple power-assisted guide assemblies and clamping assemblies, and then the traction front end of the cables is connected to an external traction device. The traction force of the traction device and multiple power-assisted drive structures drive at least one guide slide As the wheel rotates, it drives the cable forward along the cable laying path. The present invention additionally adds a power-assisted drive structure to apply force to the cable, so that the cable has active thrust when passing through the bend, reducing cable deformation. Multiple corner guide mechanisms are responsible for fixing the trajectory of the cable to avoid damage to the insulation layer of the cable due to excessive bending radius. In addition, when the cable between two adjacent corner guide mechanisms is detected to be twisted and deformed, the corresponding clamping component is controlled to clamp the cable, and then the clamping component is driven to rotate around the axis of the cable to drive the cable to twist and rotate in the opposite direction of the twisting deformation, and the twisting of the cable is corrected to a normal state, thereby improving the smoothness of cable laying, effectively eliminating the torsional stress on the cable surface, and the laying path can be set according to specifications to ensure that the cable is not damaged.

[0010] As a further improvement of the above technical solution, the twist correction mechanism also includes a tensioning drive component, which is used to drive the clamping component in the clamping state to move back and forth along the arch direction perpendicular to the axial direction of the cable, so as to drive the cable between the two adjacent corner guide mechanisms to arch and tighten.

[0011] As a further improvement of the above technical solution, in each of the power-assisted guide components, the two guide pulleys include an active guide pulley transmission-connected to the power-assisted drive structure and a slidingly arranged driven guide pulley, and the power-assisted guide component also includes an elastic member acting on the driven guide pulley, and the elastic member is used to provide an elastic force to make the driven guide pulley approach the active guide pulley, so as to push the cable to be pressed against the outer periphery of the active guide pulley.

[0012] As a further improvement of the above technical solution, in two adjacent corner guide mechanisms, the active guide pulley and the driven guide pulley in the two power-assisting guide assemblies close to the distortion correction mechanism are respectively arranged at intervals along the arch direction, and the driven guide pulley is slidingly arranged along the arch direction. When the clamping assembly drives the cable to arch and tighten, it drives at least one of the driven guide pulleys to move back to the active guide pulley, so that the cable is separated from the active guide pulley.

[0013] As a further improvement of the above technical solution, in two adjacent corner guide mechanisms, the active guide pulley and the driven guide pulley in the two power-assisting guide assemblies close to the torsion correction mechanism are arranged in opposite directions. When the clamping assembly drives the cable to arch and tighten along one end of the arch direction, it drives one of the driven guide pulleys to move back toward the active guide pulley; when the clamping assembly drives the cable to arch and tighten along the other end of the arch direction, it drives the other driven guide pulley to move back toward the active guide pulley.

[0014] As a further improvement of the above technical solution, the power-assisting guide assembly further includes a sliding frame that slides with the rotating frame, the driven guide pulley is mounted on the sliding frame, and the elastic member is connected between the sliding frame and the rotating frame.

[0015] As a further improvement of the above technical solution, the clamping assembly includes multiple clamping members and multiple clamping drive units that are respectively connected to the multiple clamping members in a ring-shaped manner to form a clamping channel for the cable to pass through. The multiple clamping drive units are used to drive the multiple clamping members to move radially along the cable, so that the multiple clamping members clamp or release the cable.

[0016] As a further improvement of the above technical solution, the clamping member is a clamping wheel, which is rotatably mounted on the driving end of the clamping drive unit, the axial direction of the clamping wheel is perpendicular to the axial direction of the cable, the outer peripheral wall of the clamping wheel abuts against the outer periphery of the cable, and the axial directions of the clamping wheel, the main wheel and the guide pulley are arranged in the same direction and perpendicular to the arching direction;

[0017] The torsion drive assembly includes a rotating ring coaxially arranged with the cable axis, a rotating drive structure connected to the rotating ring, and a plurality of clamping drive units are arranged on the rotating ring in an annular manner with the axis of the rotating ring.

[0018] The tensioning drive assembly includes a moving frame and a tensioning drive structure that drives the moving frame to reciprocate along the arching direction. The rotating ring is rotatably mounted on the moving frame.

[0019] In addition, the present invention also provides a method of use, which is applicable to the cable conduit multiple reinforcement laying device, and the method of use comprises:

[0020] According to the cable laying path, multiple corner guide mechanisms are installed at different corners, and the angle between each pair of rotating frames is adjusted according to the angle of each corner;

[0021] Installing the distortion correction mechanism between two adjacent corner guide mechanisms;

[0022] Passing the cable to be laid through the plurality of the power-assisted guide assemblies, the main wheels and the clamping assembly, and then connecting the traction front end of the cable to an external traction device;

[0023] Controlling the traction device and the plurality of power-assisted drive structures to drive the cable forward along the cable laying path;

[0024] When twisting and deformation of the cable is detected between two adjacent corner guide mechanisms, the corresponding clamping component is controlled to clamp the cable, and then the clamping component is driven to rotate around the axis of the cable by a first preset angle, driving the cable to twist and rotate in the opposite direction of the twisting and deformation. The cable is released after the twisting of the cable is corrected to a normal state.

[0025] As a further improvement of the above technical solution, the method of use further includes:

[0026] When it is detected that the traction front end of the cable suddenly slows down or stops moving forward, the clamping assembly is controlled to clamp the cable, and then the clamping assembly is controlled to move a first preset distance in the arching direction, so as to drive the cable between two adjacent corner guide mechanisms to arch and tighten, thereby driving one of the driven guide pulleys to move away from the active guide pulley;

[0027] When it is detected that the cable on the corner guide mechanism is twisted and deformed, the clamping assembly is controlled to clamp the cable, and then the clamping assembly is controlled to move a second preset distance along the end corresponding to the arching direction, so as to drive the cable between the two adjacent corner guide mechanisms to arch and tighten, and drive the driven guide pulley on the corresponding corner guide mechanism to move back to the active guide pulley, so that the cable is separated from the active guide pulley, and then the clamping assembly is controlled to rotate around the axis of the cable, driving the cable to twist and rotate by a second preset angle in the opposite direction of the twisting deformation.

[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0049] During the pulling and laying process of cables 300, existing cable laying devices can cause twisting of the cables 300 between adjacent corners, resulting in distortion and deformation stress within the cables 300 themselves. This affects the smoothness of laying and can even damage the cables 300 during the laying process. Furthermore, existing cable laying devices have poor adaptability and cannot accommodate various cable 300-turning laying scenarios. Therefore, the present invention proposes an adjustable cable conduit multi-reinforcement laying device.

[0050] like Figure 1 As shown, the cable conduit multiple reinforcement laying device of the present invention includes: a corner guide mechanism 100 and a twist correction mechanism 200.

[0051] There are multiple corner guide mechanisms 100, which are sequentially arranged along the laying path of the cable 300. The number of corner guide mechanisms 100 is determined according to the number of corners to ensure that each turning position is provided with a corner guide mechanism 100. Figure 1 As shown, this embodiment describes the principle by taking two corner guide mechanisms 100 arranged side by side as an example.

[0052] Among them, the corner guide mechanism 100 of the present invention includes two rotating frames 110, main wheels 130 and two power-assisted guide assemblies 120. The two ends of the two rotating frames 110 are respectively a hinged end and a free end. The two hinged ends are hinged to each other so that the angle between the two rotating frames 110 can be adjusted. The two power-assisted guide assemblies 120 are respectively installed on the two free ends, and the main wheels 130 are installed at the hinges of the two rotating frames 110. The main wheels 130 are used to interfere with the outer periphery of the cable 300. When in use, the cable 300 is wrapped around the outer periphery of the main wheels 130 to guide the cable 300 to turn.

[0053] like Figure 2 As shown, a connecting frame 140 is provided between the two rotating frames 110 of this embodiment, the main wheel 130 is mounted on the connecting frame 140, and the two rotating frames 110 are respectively rotatably connected to the connecting frame 140, wherein the connecting frame 140 is provided with a plurality of arc grooves 141 for angle adjustment, and the two rotating frames 110 are respectively connected to the plurality of arc grooves 141 so that the two rotating frames 110 can be rotatably adjusted, wherein a locking screw 150 is further provided between the two rotating frames 110, and the locking screw 150 has a damping soft rubber, and the two rotating frames 110 are hinged around the locking screw 150, and the angle between the two rotating frames 110 is locked by the locking screw 150.

[0054] like Figure 2 and Figure 3As shown, the power-assisted guide assembly 120 of this embodiment includes two guide pulleys and a power-assisted drive structure 121. The two guide pulleys are arranged in parallel at an interval to form a guide gap 125 for the cable 300 to pass through. The power-assisted drive structure 121 is used to drive at least one guide pulley to rotate to drive the cable 300 to be transported forward along the axial direction of the cable 300, so as to realize the power-assisted transportation of the laying of the cable 300.

[0055] The power-assisted driving structure 121 of this embodiment includes a power-assisted driving motor, wherein the power-assisted driving motor is connected to the guide pulley through a transmission belt structure.

[0056] like Figure 1 and Figure 3 As shown, the power-assisting guide assembly 120 of this embodiment also includes an adjustment frame 122, on which two guide pulleys and a power-assisting drive structure 121 are mounted. The adjustment frame 122 is adjustably arranged on the rotating frame 110 to adjust the position of the power-assisting guide assembly 120 along the extension direction of the rotating frame 110 according to actual needs.

[0057] like Figure 1 As shown, at least one distortion correcting mechanism 200 is provided, and at least one distortion correcting mechanism 200 is provided between each two adjacent corner guide mechanisms 100. The distortion correcting mechanism 200 includes a clamping component 210 and a torsion drive component 220 that are mutually transmission-connected, wherein the clamping component 210 has a clamping state for clamping the cable 300 and a loosening state for loosening the cable 300. When the clamping component 210 is in the clamping state, the cable 300 and the clamping component 210 can be relatively slidably arranged along the axial direction of the cable 300, and are relatively fixedly arranged along the circumference of the cable 300. When the clamping component 210 is in the loosening state, there is no contact between the cable 300 and the clamping component 210.

[0058] The torsion drive assembly 220 is used to drive the clamping assembly 210 in the clamping state to rotate around the axis of the cable 300, so as to drive the cable 300 to twist and rotate.

[0059] During use, according to the laying path of the cable 300, multiple corner guide mechanisms 100 are installed at different corners, and the angle between each pair of rotating frames 110 is adjusted according to the angle of each corner to adapt to various turning laying scenarios of the cable 300. The cable 300 to be laid is passed through multiple power-assisted guide assemblies 120, multiple main wheels 130 and clamping assemblies 210. The main wheels 130 guide the cable 300 to turn, thereby reducing the friction of the cable 300 at the turning node, so that the cable 300 passes through the turning position under lower tension. A twist correction mechanism is installed between two adjacent corner guide mechanisms 100. During laying, the cable 300 to be laid is passed through multiple power-assisted guide assemblies 120 and clamping assemblies 210, and then the traction front end of the cable 300 is connected to an external traction device. Under the traction force of the traction device and the multiple power-assisted drive structures 121, at least one guide pulley rotates. , driving the cable 300 to be transported forward along the laying path of the cable 300. The present invention additionally adds a power-assisted driving structure 121 to apply force to the cable 300, so that the cable 300 has active thrust when passing through the bend, reducing the deformation of the cable 300. Multiple corner guide mechanisms 100 are responsible for fixing the trajectory of the cable 300 to prevent the insulation layer of the cable 300 from being damaged due to excessive bending radius. In addition, when it is detected that the cable 300 between two adjacent corner guide mechanisms 100 is twisted and deformed, the corresponding clamping component 210 is controlled to clamp the cable 300, and then the clamping component 210 is driven to rotate around the axis of the cable 300 to drive the cable 300 to twist and rotate in the opposite direction of the twisting deformation, and the twisting of the cable 300 is corrected to a normal state, thereby improving the smoothness of the laying of the cable 300, effectively eliminating the torsional stress on the surface of the cable 300, and the laying path can be set according to the specifications to ensure that the cable 300 is not damaged.

[0060] Furthermore, the present invention takes into account that during the laying process of the cable 300, there will be a certain speed difference between the front end of the traction and the multiple corner guide mechanisms 100, and during the laying process, due to other external factors, the front end of the cable 300 will intermittently stagnate, which will cause the cable 300 to be bent, gathered and compressed between two adjacent corner guide mechanisms 100, which may easily cause the cable 300 to break away from the corner guide mechanism 100. Figure 1As shown, the distortion correction mechanism 200 of this embodiment also includes a tensioning drive component 230. The tensioning drive component 230 is used to drive the clamping component 210 in the clamping state to move back and forth along the arching direction set perpendicular to the axis of the cable 300, so as to drive the cable 300 between the two adjacent corner guide mechanisms 100 to arch and tighten. It can be understood that when it is detected that the traction front end of the cable 300 is stagnant, the tensioning drive component 230 drives the clamping component 210 in the clamping state to move a set displacement along the arching direction, so as to drive the cable 300 to arch and tighten, ensuring that the cable 300 is in a tensioned state during the laying process and can achieve dynamic balance. In this way, the cable 300 is avoided from being locally compressed, so that the cable 300 is kept in a pre-tightened state for laying, and secondly, it is ensured that the cable 300 can maintain the set tensioning posture with the corner guide mechanism 100 for transportation.

[0061] Among them, Figure 3 As shown, in each power-assisted guide assembly 120, the two guide pulleys include an active guide pulley 123 transmission-connected to the power-assisted drive structure 121 and a slidingly arranged driven guide pulley 124. The power-assisted guide assembly 120 also includes an elastic member acting on the driven guide pulley 124. The elastic member is used to provide an elastic force for making the driven guide pulley 124 approach the active guide pulley 123, so as to push the cable 300 to be pressed against the outer periphery of the active guide pulley 123. In a natural state, under the elastic force of the elastic member, the driven guide pulley 124 and the active guide pulley 123 remain clamped on the outer periphery of the cable 300, and when the outer periphery of the cable 300 becomes uneven, the cable 300 can also pass smoothly through the driven guide pulley 124 and the active guide pulley 123, and can also meet the needs of cables 300 of different sizes.

[0062] Specifically, if Figure 3 As shown, the power-assisting guide assembly 120 of this embodiment also includes a sliding frame 126 that slides with the adjustment frame 122, the driven guide pulley 124 is installed on the sliding frame 126, and the elastic member is connected between the sliding frame 126 and the adjustment frame 122. Specifically, the sliding frame 126 of this embodiment is connected with a guide rod 128 extending along the sliding direction of the driven guide pulley 124, the adjustment frame 122 is provided with a guide hole 129, the guide rod 128 is passed through the guide hole 129, and the elastic member is a spring 127, which is sleeved on the outer periphery of the guide rod 128, and the two ends of the guide rod 128 are respectively in contact with the sliding frame 126 and the adjustment frame 122.

[0063] In some embodiments, in two adjacent corner guide mechanisms 100, the active guide pulleys 123 and the driven guide pulleys 124 in the two power guide assemblies 120 close to the distortion correction mechanism 200 are arranged at intervals along the arch direction, and the driven guide pulley 124 is arranged to slide along the arch direction, such as Figure 1 As shown, if the arching direction is set to the up-down direction, the active guide pulley 123 and the driven guide pulley 124 in the power guide assembly 120 close to the distortion correction mechanism 200 are arranged in parallel with each other in the up-down direction, and the driven guide pulley 124 is arranged to slide in the up-down direction, that is, the sliding frame 126 is arranged to slide in the up-down direction relative to the adjustment frame 122.

[0064] like Figure 4 and Figure 5 As shown, when the clamping component 210 drives the cable 300 to arch and tighten, it can drive at least one driven guide pulley 124 on both sides to move back to the active guide pulley 123, so that the cable 300 is separated from the active guide pulley 123. In this way, the range of the cable 300 being tightened and arched can be expanded to increase the amount of the cable 300 being pulled up. Secondly, the conveying force of the corresponding power-assisting guide component 120 can be unloaded, which has a local deceleration effect on the cable 300.

[0065] In some embodiments, when the clamping assembly 210 drives the cable 300 to arch and tighten, it drives the two driven guide pulleys 124 on both sides to move away from the active guide pulley 123, further expanding the range of the cable 300 being tightened and arched.

[0066] like Figure 1 As shown, in the two adjacent corner guide mechanisms 100 of this embodiment, the active guide pulleys 123 and the driven guide pulleys 124 in the two power-assisting guide assemblies 120 close to the torsion correction mechanism 200 are arranged in opposite directions. When the clamping assembly 210 drives one end of the cable 300 to arch and tighten along the arching direction, it drives one of the driven guide pulleys 124 to move back to the active guide pulley 123; when the clamping assembly 210 drives the other end of the cable 300 to arch and tighten along the arching direction, it drives the other driven guide pulley 124 to move back to the active guide pulley 123.

[0067] In this way, the cables 300 in the corresponding corner guide mechanism 100 can be arched and tightened separately. When the cables 300 in the corner guide mechanism 100 on the upstream side are squeezed or transported poorly, such as Figure 4 As shown, the holding assembly 210 drives the cable 300 to arch upward, driving the upstream driven guide pulley 124 to move back to the active guide pulley 123. When the cable 300 in the corner guide mechanism 100 on the downstream side is squeezed or transported poorly, as shown in FIG. Figure 5 As shown, the clamping assembly 210 drives the cable 300 to arch downward, driving the driven guide pulley 124 on the downstream side to move back toward the active guide pulley 123.

[0068] In addition, when correcting the twisting of the cable 300, the clamping component 210 can also be used to drive the cable 300 to rotate around its axis when the cable 300 is arched and tightened, so as to drive the cable 300 to twist and rotate in the opposite direction of the twisting deformation, and correct the twisting of the cable 300 to a normal state. In this way, the cable 300 in a specific corner guide mechanism 100 can be torsionally corrected.

[0069] like Figure 6 and Figure 7 As shown, the clamping assembly 210 of this embodiment includes a plurality of clamping members and a plurality of clamping drive units 212 respectively connected to the plurality of clamping members in a ring-shaped manner to form a clamping channel 213 for the cable 300 to pass through. The plurality of clamping drive units 212 are used to drive the plurality of clamping members to move radially along the cable 300, so that the plurality of clamping members clamp or release the cable 300. This embodiment clamps the cable 300 by using a plurality of clamping members, so that the force on the cable 300 is more uniform, and when clamping the cable 300, the laying and transportation of the cable 300 can also be guided.

[0070] like Figure 6 and Figure 7 As shown, the clamping member of this embodiment is a clamping wheel 211, which is rotatably mounted on the driving end of the clamping drive unit 212. The axial direction of the clamping wheel 211 is perpendicular to the axial direction of the cable 300, and the outer peripheral wall of the clamping wheel 211 abuts against the outer periphery of the cable 300. The axial directions of the clamping wheel 211, the main wheel 130 and the guide pulley of this embodiment are arranged in the same direction and perpendicular to the arch direction. This embodiment clamps and locks the circumference of the cable 300 through the clamping wheel 211, and the cable 300 can be transported forward along its own axis to reduce the loss of the cable 300.

[0071] Among them, the torsional drive assembly 220 of this embodiment includes a rotating ring 221 coaxially arranged with the axis of the cable 300, a rotating drive structure connected to the rotating ring 221 around a transmission, and multiple clamping drive units 212 are arranged on the rotating ring 221 in a ring-shaped manner with the axis of the rotating ring 221. The rotating drive structure of this embodiment includes a driving gear 222, a rotating motor 223 connected to the driving gear 222, and a gear ring 224 fixedly sleeved on the rotating ring 221, and the driving gear 222 is meshed with the gear ring 224.

[0072] like Figure 1 As shown, the tensioning drive assembly 230 includes a movable frame 231, a tensioning drive structure 232 that drives the movable frame 231 to move back and forth along the arch direction, the rotating ring 221 is rotatably installed on the movable frame 231, and the motor is fixedly installed on the movable frame 231. The tensioning drive structure 232 and the clamping drive unit 212 of this embodiment are both linear motors. In some other embodiments, linear drive structures such as cylinders and hydraulic cylinders can be used.

[0073] In some embodiments thereof, each clamping wheel 211 is provided with a speed sensor, which is used to detect the rotation speed of the clamping wheel 211. When in use, the cable 300 is transmitted between the multiple clamping wheels 211. When the multiple clamping drive units 212 drive the multiple clamping wheels 211 to the loose position, the multiple clamping wheels 211 can be used to detect whether the cable 300 is bent or gathered. If the cables 300 of two adjacent corner guide mechanisms 100 are bent or gathered, the cable 300 will bend with the clamping wheels 212. 11 conflicts. When the cable 300 is transported, the corresponding clamping wheel 211 will be driven to rotate. At this time, the corresponding speed sensor will have feedback of the detection signal, and it will be detected that the cable 300 is bent and gathered. Then, multiple clamping drive units 212 drive multiple clamping wheels 211 to clamp the cable 300. Then, the tensioning drive component 230 drives the clamping component 210 in the clamping state to move the set displacement along the arching direction to drive the cable 300 to arch and tighten, thereby ensuring that the cable 300 is in a tensioned state during the laying process.

[0074] In addition, the present invention also proposes a method of use, which is applicable to the above-mentioned cable conduit multiple reinforcement laying device, such as Figure 8 As shown, the usage includes:

[0075] Step S100: Install multiple corner guide mechanisms 100 at different corners according to the laying path of the cable 300, and adjust the angle between each pair of rotating frames 110 according to the angle of each corner;

[0076] Step S200: installing a distortion correction mechanism 200 between two adjacent corner guide mechanisms 100;

[0077] Step S300: Pass the cable 300 to be laid through the plurality of power-assisting guide assemblies 120, the main wheels 130 and the clamping assembly 210, and then connect the traction front end of the cable 300 to an external traction device;

[0078] Step S400: Control the traction device and the plurality of power-assisted drive structures 121 to drive the cable 300 to be transported forward along the cable 300 laying path;

[0079] Step S500: When it is detected that the cable 300 between two adjacent corner guide mechanisms 100 is twisted and deformed, the corresponding clamping component 210 is controlled to clamp the cable 300, and then the clamping component 210 is driven to rotate around the axis of the cable 300 by a first preset angle, driving the cable 300 to twist and rotate in the opposite direction of the twisting deformation, and the cable 300 is released after the twisting of the cable 300 is corrected to a normal state.

[0080] In step S100 , the angle between the rotating frames 110 is adjusted by loosening the locking screws 150 . After the adjustment, the locking screws 150 are tightened to fix the rotating frames 110 .

[0081] In step S200, the clamping channel 213 formed between the plurality of clamping members is arranged opposite to the guide gap 125 between the two guide pulleys on both sides.

[0082] In step S300, the cable 300 to be laid is passed through the guide gap 125 between the two guide pulleys, the clamping channel 213 formed between multiple clamping parts and the outer periphery of the main wheel 130, and the traction front end of the cable 300 to be laid is connected to the external traction equipment.

[0083] In step S400, while the traction device is being driven, the power-assisted driving structure 121 drives the active guide pulley 123 to rotate, thereby synchronously driving the cable 300 to be transported forward.

[0084] In step S500, multiple clamping drive units 212 drive multiple clamping wheels 211 to clamp the cable 300, and then the rotating drive structure drives the rotating ring 221 to rotate, so as to drive the cable 300 to twist and rotate in the opposite direction of the twisting deformation, and correct the twisting of the cable 300 to a normal state.

[0085] In some embodiments, the twisting deformation of the cable 300 may be detected by a twist sensor, wherein the twist sensor may be installed on the corner guide mechanism 100 or between two adjacent corner guide mechanisms 100 .

[0086] Further, if Figure 9 As shown, the method of using the present invention also includes:

[0087] Step S600: When it is detected that the traction front end of the cable 300 suddenly slows down or stops moving, the clamping component 210 is controlled to clamp the cable 300, and then the clamping component 210 is controlled to move a first preset distance in the arching direction to drive the cable 300 between the two adjacent corner guide mechanisms 100 to arch and tighten, driving one of the driven guide pulleys 124 to move back to the active guide pulley 123.

[0088] When it is detected that the front end of the traction of the cable 300 is stagnant, the tensioning drive component 230 drives the clamping component 210 in the clamping state to move a set displacement along the arching direction to drive the cable 300 to arch and tighten, ensuring that the cable 300 is in a tightened state during the laying process and can achieve dynamic balance. This avoids local compression of the cable 300 and allows the cable 300 to be laid in a pre-tightened state. Secondly, it also ensures that the cable 300 can maintain the set tightening posture with the corner guide mechanism 100 for transportation.

[0089] like Figure 10 As shown, the method of using the present invention also includes:

[0090] Step S700: When it is detected that the cable 300 on the corner guide mechanism 100 is twisted and deformed, the clamping component 210 is controlled to clamp the cable 300, and then the clamping component 210 is controlled to move a second preset distance along the end corresponding to the arching direction, so as to drive the cable 300 between the two adjacent corner guide mechanisms 100 to arch and tighten, and drive the driven guide pulley 124 on the corresponding corner guide mechanism 100 to move back to the active guide pulley 123, so that the cable 300 is separated from the active guide pulley 123, and then the clamping component 210 is controlled to rotate around the axis of the cable 300, driving the cable 300 to twist and rotate by a second preset angle in the opposite direction of the twisting deformation.

[0091] When correcting the twisting of the cable 300, this embodiment can drive the cable 300 to rotate around its axis through the clamping component 210 when the cable 300 is arched and tightened, so as to drive the cable 300 to twist and rotate in the opposite direction of the twisting deformation, and correct the twisting of the cable 300 to a normal state. In this way, the cable 300 in the specified corner guide mechanism 100 can be torsionally corrected.
