Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and in particular to a cable laying device for power engineering. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, each group insulated from the others, and often twisted around a central conductor, with the entire cable covered by a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. They are widely used in many industries, including oil fields and mines, construction, machinery manufacturing, research institutions, ports and docks, shopping malls, hotels, and road and bridge construction, and their market share will continue to increase as industrial demands become more diversified.

[0003] In current power engineering, cable laying typically requires the use of traction and conveying devices. For example, invention patent CN112938618B discloses a cable traction device comprising a support frame with two rotating shafts rotatably connected to it. Mounting rings are fixedly connected to the rotating shafts, and traction rings are mounted on the outer walls of the mounting rings. Several telescopic rods are installed between the inner walls of the traction rings and the outer walls of the mounting rings. A drive mechanism on the support frame drives the two rotating shafts to rotate in opposite directions. The cable passes between the two traction rings. Under the action of the telescopic rods, the position of the traction rings on the mounting rings changes, making the distance between the outer walls of the two traction rings the same as the diameter of the cable. The outer walls of the traction rings abut against the outer walls of the cable. The drive mechanism drives the rotating shafts to rotate in opposite directions, and the cable moves through the friction between the outer walls of the traction rings and the outer walls of the cable. This improves the device's ability to adapt to cables of different diameters and expands its applicability.

[0004] However, in the aforementioned application, the cable is rolled and transported after passing between two traction rings. During the traction transport process, since the existing cable is usually wound on a drum for unwinding, and the drum is mounted on a support and is in a free-rotating state, the drum rotates along with the cable when it is pulled out. When the cable transport speed is greater than the drum unwinding speed, there is a speed difference between the drum speed and the cable transport speed, which causes the cable to be gradually tightened during transport. As the traction transport continues, the cable tension gradually increases, eventually leading to the cable breaking due to excessive tension, thus affecting the laying and transport efficiency. At the same time, the entire equipment is not convenient for timely detection of damaged cables, which may require the subsequent excavation of the damaged section for maintenance, thus affecting the laying efficiency. Therefore, a cable laying device for power engineering is proposed to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: 1. This cable laying device for power engineering, through a sliding first mounting frame and a conveying component located on the first mounting frame, when the speed difference between the cable laying end and the conveying end is inconsistent, causing the cable tension to increase, the first mounting frame will overcome the elastic force of the sliding contact and slide along the base; if the speed difference is too large and triggers the limit position, the sliding contact will touch the touch switch and immediately cut off the conveying power. This structure effectively avoids forced traction damage caused by speed mismatch and improves the safety and controllability of the laying process.

[0017] 2. This cable laying device for power engineering features a rotating detection ring driven by a servo motor in the middle of the conveying path. Through the synchronous operation of an industrial camera and a submillimeter-wave flaw detector, it performs a 360° circular scan of the cable passing through the ring's center. This not only automatically identifies and marks surface damage such as scratches and insulation breaks on the cable, but also deeply detects hidden defects such as air holes and insulation damage. It achieves the integration of laying and detection, making it easy for operators to locate and treat damaged sections in a timely manner, thus ensuring the quality of cable laying.

[0018] 3. This cable laying device for power engineering, through the limiting and guiding mechanisms at both ends and the tension monitoring components on both sides of the conveying port, can stabilize the cable and monitor the slight angular deviation of the cable in the horizontal and vertical directions in real time. When the deviation causes the cable to squeeze the corresponding pressure sensor, the tension change can be displayed in real time and an early warning can be given in time, thereby assisting the operator to accurately adjust the laying angle and effectively prevent hidden damage caused by excessive bending.

[0019] 4. This cable laying device for power engineering can be adjusted by rotating the threaded rod to drive the corresponding lifting plate. The entire device can be moved and supported by the moving wheels to increase the ease of movement of the entire device. When the base contacts the ground, it provides stable support for the limiting conveying mechanism, detection mechanism and limiting guide mechanism, and ensures stable laying and conveying of the cable.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following is combined with Figures 1 to 7 This application describes a cable laying device for power engineering provided in an embodiment.

[0026] like Figure 1 and Figure 2 As shown, a cable laying device for power engineering according to the present invention includes: The base 1 has a convex shape at both ends. The base 1 serves as the supporting base for the entire device. The convex shape at both ends of the base 1 increases the support area. The direction of the line connecting the two ends of base 1 is horizontal, which is the direction of horizontal cable transmission. The direction perpendicular to the "horizontal" direction is "vertical". The limiting conveying mechanism 2 is installed in the middle area of ​​the upper surface of the base 1 to provide the main driving force and to block and limit the conveying of the cable in the lateral direction. The detection mechanism 3 is installed on the upper surface of the base 1 and located in the middle of the limiting conveying mechanism 2. The detection mechanism rotates axially around the cable during the conveying process of the limiting conveying mechanism 2 to detect whether the cable is damaged and the degree of damage. Two limiting and guiding mechanisms 4 are respectively installed on the upper surfaces of the first and last ends of the base 1. They block and limit the horizontal height of the cable and guide the cable. They also work with the limiting and conveying mechanism 2 to stably guide the cable and ensure that the cable enters and leaves the limiting and conveying mechanism 2 in the correct posture. The limiting conveying mechanism 2 includes a pair of first mounting brackets 21, a pair of second mounting brackets 27, a pair of support rods 218, a pair of touch switches 210, and a cover 23; A set of first mounting brackets 21 are symmetrically slidably mounted on the base 1; a set of second mounting brackets 27 are symmetrically fixed on the base 1; a cover 23 is fixedly connected to the side of each of the two first mounting brackets 21 away from the base, so that the cover spans the two first mounting brackets; one end of each of a set of support rods 218 is symmetrically fixed to the end of the cover 23 near the base 1, and the other end of each support rod 218 extends downward and is connected to the base 1; The first mounting frame 21 and the second mounting frame 27 are jointly equipped with a conveying assembly for conveying cables, which is used to drive the cables to be laid and conveyed in a horizontal direction. The conveying assembly is also rotatably connected to the baffle 23, so that when the cable conveyed by the conveying assembly is in a tight state, it can drive the first mounting frame 21 and the baffle 23 to slide towards the side closer to the second mounting frame 27. A set of grooves 28 are provided on the upper surface of the base 1, and the set of grooves 28 are symmetrically distributed on the opposite side of a set of first mounting brackets 21; a touch switch 210 is installed on the inner wall of the groove 28 away from the support rod 218, and a sliding contact member is provided at the end of the support rod 218 away from the cover 23, which is slidably connected in the groove 28 and used to abut against the touch switch 210, so that when the cable is tightened during the conveying process, the conveying component drives the sliding contact member to abut against the touch switch 210, and the touch switch 210 controls the conveying component to stop conveying; Furthermore, both of the touch switches 210 are electrically connected to the conveyor motor 25, so that when the touch switches 210 are resisted, they are used to control the conveyor motor 25 to stop running.

[0027] Specifically, there are two of each of the first mounting bracket 21 and the second mounting bracket 27. The two first mounting brackets 21 are symmetrically distributed laterally along the line connecting the two ends of the base, and the two second mounting brackets 27 are also symmetrically distributed laterally along the line connecting the two ends of the base. The two first mounting brackets 21 and the two second mounting brackets 27 are symmetrically distributed longitudinally along the detection mechanism 3 as the center, that is, in the direction perpendicular to the "lateral" direction, for horizontal cable transmission. It should be noted that the opposite side of a set of first mounting brackets 21 and the opposite side of a set of second mounting brackets 27 are both concave, that is, they have a concave cavity. The conveying assembly is installed in the concave cavity of the first mounting bracket 21 and the second mounting bracket 27. The concave cavity is used to reserve installation space for the conveying assembly.

[0028] Specifically, the conveying assembly consists of four pairs of guide rollers 22, four conveyor belts 26, a conveyor motor 25, and two transmission gears 24; A pair of guide rollers 22 are symmetrically and rotatably mounted on the inner side of each first mounting frame 21 and the inner side of each second mounting frame 27. The ends of the two guide rollers 22 on the two first mounting frames 21 that are away from the conveyor motor 25 and away from the base 1 are rotatably connected to the baffle 23. Four conveyor belts 26 are respectively sleeved on the outer surface of the four pairs of guide rollers 22. The conveyor motor 25 is fixed on the side of one of the first mounting frames 21 away from the base 1, and the output shaft of the conveyor motor 25 is fixed to the upper end of the corresponding guide roller 22. Two transmission gears 24 are respectively fixedly connected to the upper ends of the two guide rollers 22 on the two first mounting frames 21 that are away from the conveyor motor 25, and the two transmission gears 24 mesh with each other. It should be noted that an arc-shaped conveying groove is provided in the middle of the outer surface of each conveyor belt 26 to further limit and guide the cable, so that the cable can be conveyed in the center along the gap formed by the respective conveying grooves on the two opposite conveyor belts 26. The two transmission gears 24 are located inside the baffle 23, so that the two meshing transmission gears 24 are covered by the baffle 23 to block some of the dust in the air and improve the smoothness and stability of the transmission gears 24 during operation.

[0029] Preferably, the upper surface of the base 1 is also equipped with a set of two guide rails 211, and the two first mounting brackets 21 are provided with sliding grooves corresponding to the guide rails 211 on the side of the base 1, so that the two first mounting brackets 21 can be slidably connected to the two guide rails 211 through the sliding grooves, thereby improving the sliding stability of the first mounting brackets 21 on the base 1.

[0030] Therefore, during the cable conveying process via the conveying components on the first mounting frame 21 and the second mounting frame 27, if the speed of the cable release end is inconsistent with the speed conveyed by the guide roller 22 corresponding to the conveying motor 25 and the conveyor belt 26, the cable conveyed by the guide roller 22 and the conveyor belt 26 on the first mounting frame 21 will be in a tight state. This causes the first mounting frame 21 to slide along the base 1 and simultaneously drive the support rod 218 and the sliding contact member at the end of the support rod 218 to slide horizontally towards the side closer to the second mounting frame 27. At the same time, when the speed difference is too large, and the first mounting frame 21 is restricted from gradually sliding towards the second mounting frame 27, the sliding contact member gradually slides until it touches the touch switch 210, causing the conveying motor 25 on the first mounting frame 21 to stop operating and conveying, so as to avoid damage to the cable caused by the forced conveying when the speed of the cable release end and the laying conveying end are inconsistent, thereby improving the conveying effect.

[0031] In some embodiments, continue to refer to Figure 3 The sliding contact component consists of a pair of guide blocks 212, a pair of guide rods 213, a pair of sleeve rods 214, a pair of support springs 215, a pair of scale marks 216 and a pair of indicator blocks 217; A pair of guide blocks 212 are slidably connected to a pair of grooves 28 respectively, and each guide block 212 is fixed to the end of the support rod 218 in the corresponding groove 28 away from the cover 23. A pair of guide rods 213 are fixedly connected to the inner wall of the pair of grooves 28 away from the touch switch 210, and each guide rod 213 passes through its corresponding guide block 212, so that the guide block 212 can slide along the guide rod 213. A pair of sleeve rods 214 are fixed to the side of the pair of guide blocks 212 near the touch switch 210. A pair of support springs 215 are fixed between the pair of guide blocks 212 and the inner wall of the corresponding groove 28, for elastic support of the guide blocks 212 slidably connected in the groove 28. A pair of indicator blocks 217 are fixed at the connection between the pair of support rods 218 and the pair of guide blocks 212. A pair of scale marks 216 are set on the upper surface of the base 1 and located on the opposite side of the pair of indicator blocks 217.

[0032] It should be noted that each guide block 212, each guide rod 213, each sleeve rod 214, and each support spring 215 are located in the corresponding groove 28. The end of the indicator block 217 away from the first mounting bracket 21 is a pointed tip, so that the operator can easily observe the position of the indicator block 217 pointing to the scale mark 216. The starting section, middle section, and end section of the scale mark 216 pointed to by the indicator block 217 correspond to the point where the difference between the unwinding speed and the conveying speed of the cable is small, large, and maximum during the conveying process, respectively.

[0033] Specifically, the connection end between the sleeve 214 and the guide block 212 is an open end, and the end of the sleeve 214 away from the guide block 212 is a closed end. The guide block 212 has a circular hole in the middle for the guide rod 213 to pass through, so that each guide block 212 can slide stably horizontally on the guide rod 213 through the circular hole in the middle. At the same time, the closed end of the sleeve 214 presses against the touch switch 210 as it slides horizontally with the guide block 212.

[0034] Therefore, since the guide block 212 and the sleeve rod 214 can slide horizontally along the guide rod 213, and the guide block 212 is fixed to the support rod 218, the guide rod 213 can support the cover 23 and slide horizontally on the base 1 along with the cover 23 and the first mounting frame 21. At the same time, the support spring 215 in the groove 28 can elastically support the guide block 212, so that when the cable is conveyed by the conveyor belt 26 on the first mounting frame 21 and the tension increases, the first mounting frame 21 needs to overcome the elastic force of the support spring 215 and gradually slide horizontally on the base 1. Conversely, when the cable tension is small, the conveyor belt 26 on the first mounting frame 21 can still continuously convey and lay the cable.

[0035] In some embodiments, continue to refer to Figure 5The testing mechanism 3 consists of a support 31, a servo motor 33, a drive gear 34, two sets of guide frames 35, a rotating ring 36, a rack 37, an industrial camera 38, and a submillimeter wave flaw detector 39. The bracket 31 is fixed on the base 1 and located between the first mounting bracket 21 and the second mounting bracket 27. The servo motor 33 is installed in the middle of the side of the bracket 31 away from the base 1. The drive gear 34 is fixed on the output shaft of the servo motor 33. Two sets of guide frames 35 are symmetrically fixed inside the bracket 31. The rotating ring 36 is rotatably connected between the two sets of guide frames 35. The rack 37 is fixedly connected in the middle of the outer surface of the rotating ring 36 and meshes with the drive gear 34. The industrial camera 38 and the submillimeter-wave flaw detector 39 are symmetrically installed on the inner wall of the rotating ring 36 for internal and external identification and flaw detection of the cable passing through the rotating ring 36.

[0036] Specifically, the bracket 31 is U-shaped, and there are two guide frames 35 in each group. Each pair of guide frames 35 has an arc-shaped guide groove on one side to support the guide rotating ring 36, so that the rotating ring 36 is installed between the two groups of guide frames 35. During rotation, the rack 37 on the outer surface of the rotating ring 36 passes through the gap between each group of guide frames 35. At the same time, a rectangular hole is opened in the middle of the side of the bracket 31 away from the base 1 for the drive gear 34 and the rack 37 to rotate, so that the meshing part of the drive gear 34 and the rack 37 can pass through the bracket 31 and have rotation space.

[0037] It should be noted that a support chamber 32 is also installed in the middle of the side of the bracket 31 away from the base 1, which covers the servo motor 33 and the drive gear 34. Control panels are installed on the side of the support chamber 32 away from the bracket 31 and on the side close to the two moving support mechanisms 5. The control panels are electrically connected to the industrial camera 38 and the submillimeter-wave flaw detector 39, respectively. The control panels have built-in receivers and display panels for receiving the values ​​and images detected by the industrial camera 38 and the submillimeter-wave flaw detector 39. At the same time, the control panels also have built-in alarms to issue an alarm when the detected parameters and images are inconsistent with the set parameters, so as to remind the operator that this section of the cable is damaged and the operator can make timely maintenance.

[0038] Therefore, the submillimeter-wave flaw detector 39 and industrial camera 38 located on the rotating ring 36 can, under the action of the servo motor 33 driving the drive gear 34 to drive the rack 37 and the rotating ring 36 to rotate 180 degrees in both directions, detect internal defects such as scratches, air holes, and insulation damage that are invisible to the naked eye in the cable passing through the rotating ring 36 in a ring shape, and automatically identify and mark external damage such as scratches, sheath breaks, and pinholes on the cable surface, so as to facilitate operators to maintain the damaged sections of the cable in a timely manner and improve the laying effect.

[0039] In some embodiments, continue to refer to Figure 4Tension monitoring components 29 are provided at opposite ends of the first mounting frame 21 and the second mounting frame 27 to monitor the cable tension online during the laying and transportation process; Each tension monitoring assembly 29 consists of two pairs of mounting rings 291, two mounting rods 292, two guide cylinders 293, two mounting plates 294, and two first pressure sensors 295; Each pair of mounting rings 291 is fixed to the outer surface of the opposite end of the first mounting bracket 21 and the second mounting bracket 27. Each pair of mounting rings 291 on each pair of first mounting brackets 21 and each pair of second mounting brackets 27 are symmetrically distributed laterally along the cable conveying direction. Each pair of mounting rings 291 are symmetrically distributed vertically. The two ends of each mounting rod 292 are slidably connected to the same pair of mounting rings 291. The two ends of each mounting plate 294 are fixed to the same pair of mounting rings 291. Each guide cylinder 293 is rotatably connected to the middle of a corresponding mounting rod 292. Each first pressure sensor 295 is installed on the side of a corresponding mounting plate 294 near the guide cylinder 293, and the middle of each guide cylinder 293 abuts against the force-bearing end of the corresponding first pressure sensor 295.

[0040] It should be noted that there are two sets of mounting rings 291, and each set of mounting rings 291 is vertically arranged and symmetrically distributed on the opposite ends of the first mounting frame 21 and the second mounting frame 27, so that each set of mounting rings 291 supports a corresponding mounting rod 292, and the mounting rod 292 can be slidably mounted on the mounting ring 291.

[0041] Specifically, the mounting rod 292 is U-shaped, and the diameter of the mounting rod 292 is adapted to the inner diameter of the mounting ring 291. Both ends of each mounting rod 292 pass through the same pair of mounting rings 291, and the end passing through the mounting rings 291 is L-shaped, so that each mounting rod 292 can be stably slidably mounted on the same pair of mounting rings 291 and cannot be separated from the mounting rings 291. At the same time, the mounting rod 292 drives the corresponding guide cylinder 293 to slide towards the mounting plate 294, thereby squeezing the first pressure sensor 295 on the mounting plate 294.

[0042] Therefore, the four guide cylinders 293 at opposite ends of the two first mounting brackets 21 and the second mounting bracket 27 can guide the cable, and when the cable deviates laterally, that is, when the cable's entry and exit sections bend at an angle away from either the first mounting bracket 21 or the second mounting bracket 27, the corresponding guide cylinder 293 will be squeezed. This will cause the corresponding guide cylinder 293 to squeeze the first pressure sensor 295 that is in contact with it. The greater the pressure on the first pressure sensor 295, the greater the cable tension. When the pressure exceeds the set value, it indicates that the cable has been bent at an excessive angle during laying and transportation, and is prone to damage. Therefore, the first pressure sensor 295, in conjunction with its corresponding control panel, prompts the operator to check and adjust the cable laying orientation.

[0043] In some embodiments, continue to refer to Figure 6 There are two limit guide mechanisms 4, which are installed at the beginning and end of the base 1 respectively. Each limit guide mechanism 4 consists of two vertical rods 41, four support rings 42, four mounting blocks 43, four second pressure sensors 44, four guide wheels 45, two horizontal rods 46 and four pressure rods 47. In each limiting guide mechanism 4, two vertical rods 41 are symmetrically fixed to the upper surface of the first or last end of the base 1. Four support rings 42 are slidably connected to the outer surface of the two vertical rods 41 in pairs. That is, two support rings 42 are spaced apart on the outer surface of each vertical rod 41, and two support rings 42 on the same vertical rod 41 form a group. Two horizontal rods 46 are fixedly connected between the two vertical rods 41, and the two ends of each horizontal rod 46 are fixed between the two support rings 42 in one of the corresponding groups. Each guide wheel 45 is rotatably connected to the middle of a corresponding horizontal rod 46. The two horizontal rods 46 and the two guide wheels 45 are symmetrically distributed vertically to stabilize the cable. Four pressure rods 47 are symmetrically fixed to the two horizontal rods 46 in pairs. In other words, two pressure rods 47 are fixed on each horizontal bar 46. The two pressure rods 47 on the same horizontal bar 46 form a group. Specifically, two pressure rods 47 are fixed symmetrically on each horizontal bar 46, and the two pressure rods 47 on one horizontal bar 46 are vertically symmetrical with the two pressure rods 47 on the other horizontal bar 46. The four mounting blocks 43 are installed on the two vertical bars 41 in pairs. That is, two mounting blocks are installed on each vertical bar 41, and the two mounting blocks 43 on the same vertical bar 41 form a group. On the same vertical bar 41, the two support rings 42 are located between the two mounting blocks 43. The four mounting blocks 43 are connected to the four pressure rods 47 in a one-to-one correspondence, and the four second pressure sensors 44 are installed on the side of each of the four mounting blocks 43 facing the pressure rod 47 in a one-to-one correspondence.

[0044] It should be noted that the middle part of the guide wheel 45 is concave, and the outer diameter of the guide wheel 45 gradually increases from the middle to both ends, so that the two guide wheels 45 on the same side can be centered to guide and guide the cable. Each vertical rod 41 has an external thread on its upper outer surface, and a nut is threaded onto the upper outer surface of each vertical rod 41 to prevent the support ring 42, which is sleeved on the vertical rod 41, from falling out. The mounting block 43 has a mounting hole that slides on the vertical rod 41 at the connection with the vertical rod 41. Therefore, after tightening the nut, the support ring 42 and the mounting block 43, which are sleeved on the vertical rod 41 in sequence, can be supported by contact. After the two guide wheels 45 are tightened, a certain gap needs to be left to facilitate the passage of the cable.

[0045] Furthermore, the second pressure sensor 44 on the mounting block 43 and the first pressure sensor 295 on the mounting plate 294 are both electrically connected to the control panels on both sides of the support chamber 32, so that the control panels can display the pressure values ​​transmitted by the first pressure sensor 295 and the second pressure sensor 44, and generate an alarm when the pressure exceeds the set value.

[0046] Therefore, the guide wheels 45 located on the two crossbars 46 can guide the cable vertically in a centered manner. When the cable deviates vertically, that is, when the cable's entry and exit sections bend at an angle away from either guide wheel 45, the cable will squeeze the corresponding guide wheel 45. This causes the crossbars 46 supporting the guide wheels 45 to drive the pressure rods 47 to squeeze the second pressure sensor 44. The greater the pressure on the second pressure sensor 44, the greater the cable tension. When the pressure exceeds the set value, it indicates that the cable has bent too much at a vertical angle during laying and transportation, making it prone to damage. Therefore, the second pressure sensor 44, in conjunction with its corresponding control panel, prompts the operator to check and adjust the cable's laying position.

[0047] In some embodiments, continue to refer to Figure 7 It also includes two movable support mechanisms 5, which are respectively installed on both sides of the base 1. The two movable support mechanisms 5 are symmetrically distributed laterally along the opposite sides of the two first mounting frames 21 and the two second mounting frames 27, and are used to lift the base 1 so that the whole device can be moved easily. The movable support mechanism 5 consists of two support blocks 51, two sleeves 52, a lifting plate 53, a threaded rod 54, a U-shaped rod 55, and two movable wheels 56; In each movable support mechanism 5, two support blocks 51 are symmetrically fixed on one side of the base 1, and the two ends of the U-shaped rod 55 are respectively fixed on the two support blocks 51. Two sleeves 52 are slidably connected to the two ends of the U-shaped rod 55 that are connected to the two support blocks 51. The two ends of the lifting plate 53 are respectively fixedly connected to the two sleeves 52. The threaded rod 54 is rotatably connected to the middle of the lifting plate 53, and the end of the threaded rod 54 away from the lifting plate 53 passes through the U-shaped rod 55 and is threadedly connected to the U-shaped rod 55. Two movable wheels 56 are respectively fixedly installed at both ends of the lifting plate 53.

[0048] It should be noted that the side of the base 1 away from the limiting conveying mechanism 2 is provided with several anti-slip textures to improve the friction and stability of the base 1 when it contacts the ground.

[0049] Specifically, a threaded hole is provided in the middle of the U-shaped rod 55 for the threaded rod 54 to pass through, and the threaded hole is adapted to the thread on the outer surface of the threaded rod 54, so that the rotating threaded rod 54 can be adjusted up and down in the corresponding U-shaped rod 55. The thread on the outer surface of the threaded rod 54 is a triangular thread to improve the stability of the threaded connection between the threaded rod 54 and the U-shaped rod 55 when it is not rotating.

[0050] Therefore, during the rotation of each threaded rod 54, the corresponding lifting plate 53 can be adjusted for lifting. When the two lifting plates 53 are adjusted to be lowered and the base 1 is lifted by the moving wheel 56, the entire device can be moved and supported by the moving wheel 56 to increase the mobility of the entire device. When the lifting plate 53 is raised, the moving wheel 56 is separated from the ground. When the base 1 contacts the ground, it provides stable support for the limiting conveying mechanism 2, the detection mechanism 3 and the limiting guide mechanism 4, and provides stable laying and conveying of the cable.

[0051] The working principle in the above embodiments is as follows: During the cable laying and transportation process, the conveyor motor 25 starts and drives the corresponding guide roller 22 to rotate. Through the meshing of the transmission gear 24, the dust is protected by the cover 23. The power is synchronously transmitted to all the guide rollers 22 of the two first mounting frames 21, driving the two conveyor belts 26 on the first mounting frame 21 to rotate synchronously and in the same direction, using friction to clamp and transport the cable forward. If the unloading speed is slower than the conveying speed, the cable is tightened, and the tension increases. At this time, the friction between the conveyor belt 26 on the first mounting frame 21 and the cable increases. This tension is transmitted through the guide roller 22 to the end rotatably connected to the baffle 23, thereby causing the baffle 23 and the first mounting frame 21 fixed thereto to overcome the elastic force of the support spring 215 and slide along the guide rail 211 toward the second mounting frame 27. At this time, the indicator block 217 gradually moves toward the middle and end of the scale mark 216, indicating to the operator that the tension is increasing. If the speed difference is too large and the sliding distance continues to increase, the sleeve 214 fixed on the guide block 212 will eventually abut against the touch switch 210. The touch switch 210 triggers a signal to immediately cut off the power to the conveyor motor 25, achieving an emergency stop, thereby avoiding cable damage caused by forced conveying. Quality Inspection: During the smooth transport of the cable, it needs to be inspected by inspection agency 3 located in the middle: During cable transport, the servo motor 33 starts and drives the rack 37 on the outer surface of the rotating ring 36 through the drive gear 34, so that the rotating ring 36 rotates 180 degrees in both directions around the cable under the support of the guide frame 35. An industrial camera 38 and a submillimeter-wave flaw detector 39, fixed to the inner wall of the rotating ring 36, rotate synchronously to perform 360-degree inspection on the cable passing through the center of the ring. Industrial camera 38 is responsible for detecting surface defects such as scratches and tears on the cable surface; The submillimeter-wave flaw detector 39 is responsible for detecting hidden dangers inside cables, such as scratches, pores, and insulation damage that are not visible to the naked eye. Tension monitoring: The detection data is transmitted in real time to the control panels on both sides of the support chamber 32. When damage is detected, the built-in alarm will sound, reminding the operator to mark and deal with the damaged section. To prevent cable damage due to excessive bending angles at the entry and exit points, the entire device is equipped with a bidirectional pressure detection structure. Lateral tension monitoring: If the cable bends laterally at the port where the cable enters and leaves the limiting conveyor mechanism 2, it will squeeze the rotatable guide cylinder 293. The guide cylinder 293 will then compress the first pressure sensor 295 that is in contact with it. The greater the pressure value, the greater the lateral tension or bending angle. If the set threshold is exceeded, an alarm will be triggered. Vertical tension monitoring: In the limiting guide mechanism 4 at the beginning and end of the base 1, if the cable is bent vertically, it will squeeze the guide wheel 45. The guide wheel 45 drives the pressure rod 47 to move through the cross bar 46, which in turn squeezes the second pressure sensor 44. The pressure value is uploaded to the control panel in real time. If the limit is exceeded, an alarm will be triggered, prompting the operator to adjust the laying angle or cable laying angle. Overall portability: By rotating the threaded rod 54, the lifting plate 53 is driven to descend using the threaded transmission. The lifting plate 53 drives the two sets of sleeves 52 to slide down along the U-shaped rod 55 until the moving wheel 56 contacts the ground and lifts the entire base 1. At this point, the device can be pushed to the new work position. After it is in place, the threaded rod 54 is rotated in the opposite direction to retract the moving wheel 56, so that the anti-slip texture on the bottom of the base 1 contacts the ground, ensuring the stability during installation.
