Description

Technical Field

[0001] This application relates to the field of cable laying, and in particular to a cable laying device and a construction method for laying cables. Background Technology

[0002] Cable laying refers to the process of rotating a cable reel to lay out the cable along a surveyed route, thus forming a cable line. Depending on the application, it can be divided into several laying methods, including overhead, underground (duct and direct burial), underwater, wall, and tunnel laying. Choosing the appropriate cable laying method is crucial for ensuring the transmission quality, reliability, and ease of construction and maintenance. When laying cables in vertical shafts or on slopes, cable laying equipment must be installed.

[0003] Chinese patent CN212033647U discloses a cable laying trolley, comprising an arc-shaped mounting plate with two sliding blocks symmetrically arranged on the plate along its arc direction; each sliding block has a vertically opening groove; a slider is slidably arranged within the groove; a roller is rotatably arranged between the two sliders; a lead screw is vertically rotatably arranged within the groove, passing through the slider; the upper end of the lead screw protrudes from the top end face of the sliding block; pulleys are fixedly fitted onto the upper ends of both lead screws, with the upper ends of the lead screws protruding from the pulleys; the two pulleys are connected by a transmission belt. When laying cables into a vertical shaft, the arc-shaped mounting plate is placed at the top opening of the shaft, and then the cable is passed between the arc-shaped mounting plate and the roller, extending towards the bottom of the shaft to lay the cable within the shaft.

[0004] The aforementioned technologies have the following drawbacks: the cables are heavy, and during the laying of cables in the shaft, the downward speed of the cables is fast and difficult to control under the action of gravity. This makes it easy for the cable end to collide violently with the bottom of the shaft when it reaches the bottom, causing damage to the cable. Therefore, improvements are needed. Summary of the Invention

[0005] To address the issue of cable damage, this application provides a cable laying device and a construction method for laying cables.

[0006] Firstly, the cable laying device provided in this application adopts the following technical solution:

[0007] A cable laying device for laying cables includes a mounting frame with a cable reel rotatably connected to it. A driving mechanism is provided on the mounting frame, comprising a pushing component and a fixing component for clamping the cable. Both the pushing component and the fixing component are connected to the mounting frame. The pushing component is connected to the fixing component via a connecting component. Rotation of the pushing component drives the cable to move, causing the connecting component to rotate, thus moving the fixing component closer to or further away from the cable.

[0008] By employing the above technical solution, one end of the cable is rotated off the cable reel, and the reel continues to rotate, allowing the cable to pass through the fixing component and be placed at the advancing component. The advancing component is then activated, causing it to rotate, which in turn rotates the connecting component, moving the fixing component away from the ground until it abuts against the side wall of the cable. This mutual compression force on the cable's side wall secures the cable to the mounting frame. Next, the mounting frame is moved to the shaft opening, and the advancing component is rotated, causing the connecting component to reverse, moving the fixing component closer to the ground until it abuts against the side wall of the cable. At this point, the fixing component completely separates from the cable's side wall. The advancing component continues to rotate, causing it to slide against the cable's side wall, transporting the cable towards the bottom of the shaft, thus achieving cable laying within the shaft. Only with the advancement component and the separation of the fixing component can the cable move, preventing it from rapidly descending under gravity. This avoids a violent impact when the cable reaches the bottom of the shaft, reducing the risk of damage to the cable end and increasing its service life.

[0009] Optionally, the propulsion assembly includes a drive unit and two propulsion units, both of which are connected to the mounting frame. The two propulsion units are symmetrical about the central axis of the mounting frame. When the drive unit moves, it drives the two propulsion units to rotate simultaneously, thereby driving the cable to move.

[0010] By adopting the above technical solution, when the mounting frame moves to the opening of the shaft, the drive unit is activated, causing it to move the propulsion unit away from the cable reel, thus causing the propulsion unit to rotate. When the propulsion unit comes into contact with the side wall of the cable, it continues to move, causing the propulsion unit and the cable to slide against each other, thereby pushing the cable away from the cable reel. When the end of the cable away from the cable reel moves to the opening of the shaft, under the action of gravity, the cable moves vertically downward, realizing the laying of the cable in the shaft.

[0011] Optionally, the driving unit includes a propulsion drive component and a propulsion rod. The propulsion drive component is fixedly mounted on the mounting frame, and the output end of the propulsion drive component is connected to the propulsion rod to drive the propulsion rod to move along the length direction of the mounting frame. The propulsion unit is connected to the end of the propulsion rod.

[0012] By adopting the above technical solution, when the mounting frame moves to the opening of the shaft, the propulsion drive is activated to perform a telescopic movement, pushing the propulsion rod along the length of the mounting frame towards or away from the cable reel. This causes the propulsion part to rotate around the end of the propulsion rod, thereby causing the propulsion part to continuously slide against the side wall of the cable, allowing the cable to move along the length of the mounting frame and extend towards the bottom of the shaft under the action of gravity. This enables the cable to be laid in the shaft. By driving the cable movement through the propulsion part, compared to using the cable's gravity to move downwards, the cable is less likely to violently impact the bottom of the shaft, thus making the cable less prone to damage and extending its service life.

[0013] Optionally, the propulsion unit includes a moving rod, a fixed rod, and a cam. One end of the moving rod is rotatably connected to a drive unit, and the other end is rotatably connected to a fixed rod. The end of the fixed rod away from the moving rod is fixedly connected to the side wall of the cam. The cam is rotatably connected to a mounting bracket. A propulsion plate is provided on the mounting bracket. A propulsion ring groove for the fixed rod to pass through is provided on the propulsion plate. The propulsion ring groove is coaxial with the cam and rotatably connected to the cam. A limit component is provided in the propulsion ring groove. The limit component is used to restrict the fixed rod from moving in one direction in the propulsion ring groove. The fixed rod passes through the propulsion ring groove and moves in the propulsion ring groove to drive the cam to rotate.

[0014] By adopting the above technical solution, the propulsion drive is activated, driving the propulsion rod to move towards the cable reel. This causes both moving rods to move simultaneously towards the cable reel. The inner wall of the propulsion ring groove abuts against the side wall of the fixed rod, guiding the fixed rod so that it can only move along the trajectory of the propulsion ring groove. This causes the moving rod to rotate about the end of the propulsion rod, which in turn causes the fixed rod to move away from the cable along the trajectory of the propulsion ring groove. Simultaneously, this drives the two cams to rotate synchronously until the fixed rod moves to the end of the propulsion ring groove near the cable reel. At this point, the outer edge of the cam protrusion abuts against the side wall of the cable. The propulsion drive is then used to drive the propulsion rod to move away from the cable reel, causing both moving rods to move simultaneously away from the cable reel. This causes the fixed rod to move towards the cable along the trajectory of the propulsion ring groove, resulting in the cam protrusion sliding against the side wall of the cable, pushing the cable away from the cable reel, thus achieving cable unloading. When the cable moves to the opening of the shaft, under the action of gravity, the end of the cable is inserted into the shaft and moves vertically downward, thus realizing the laying of the cable in the shaft.

[0015] Optionally, the connecting assembly includes a mounting rod, a connecting rod, and two baffles. Both baffles are connected to the push rod and are arranged along the length of the mounting frame. The mounting rod is vertically arranged, with one end located between the two baffles and the other end fixedly connected to the connecting rod. The mounting rod is perpendicular to the connecting rod. The mounting frame is provided with a mounting seat, and the side wall of the connecting rod is rotatably connected to the mounting seat. Both ends of the connecting rod are connected to the mounting frame through support springs.

[0016] By adopting the above technical solution, the drive component moves the push rod closer to the cable reel until a baffle away from the cable reel abuts against the mounting rod, and pushes the mounting rod closer to the cable reel, causing the connecting rod to rotate around the connection between the connecting rod and the mounting base. This causes the end of the connecting rod closer to the cable reel to compress the support spring, and drives the fixing component to move closer to the ground, thereby causing the fixing component to move away from the cable. At the same time, the fixing rod moves away from the cable along the trajectory of the push ring groove. When the fixed rod drives the cam protrusion to abut against the side wall of the cable, the fixing component completely separates from the side wall of the cable. The propulsion drive then moves the push rod away from the cable reel until a baffle near the cable reel abuts against the mounting rod, causing the mounting rod to move away from the cable reel. This causes the connecting rod to rotate, and the end of the connecting rod away from the cable reel compresses the support spring, moving the fixing assembly away from the ground. This causes the fixing assembly to move closer to the cable, and simultaneously, the fixing rod moves the cam's protrusion closer to the cable. The cam's protrusion then slides against the side wall of the cable, moving the cable along the length of the mounting frame away from the cable reel. Once the cam's protrusion is completely separated from the cable's side wall, the fixing assembly abuts against the cable's side wall, applying mutual pressure to secure the cable to the mounting frame. This prevents the cable from moving further under gravity, thus preventing the cable end from violently impacting the bottom of the shaft, reducing cable damage, and extending the cable's service life.

[0017] Optionally, the fixing component includes a support rod and two clamping parts. A support block is provided on the mounting bracket. The support rod is vertically arranged, and one end of the support rod is inserted into the support block and slides in the support block. The other end is rotatably connected to the end of the connecting rod away from the mounting rod. The mounting seat is located between the mounting rod and the support rod. The two clamping parts are symmetrical about the central axis of the support rod, and the clamping parts are rotatably connected to the support block.

[0018] By adopting the above technical solution, when the cam's protrusion abuts against the side wall of the cable and drives the cable to move, a baffle away from the cable reel pushes the mounting rod, causing the end of the connecting rod near the cable reel to compress the support spring, driving the support rod to move towards the ground, so that the two clamping parts move away from the cable at the same time until the clamping parts separate from the side wall of the cable, so that the clamping parts will not interfere with the movement of the cable, making it easier for the cable to move to the bottom of the shaft, and realizing the laying of the cable in the shaft. When the cam's protrusion is completely separated from the cable's sidewall, a baffle near the cable reel pushes the mounting rod, causing the end of the connecting rod away from the cable reel to compress the support spring. This moves the support rod away from the ground, causing both clamping parts to move simultaneously away from the cable until they come into contact with it. Both symmetrical sidewalls of the cable are subjected to compressive force towards the cable's center, creating a relative force between the two clamping parts. This fixes the cable to the mounting frame, preventing it from rapidly moving towards the bottom of the shaft under gravity. In other words, the cable end will not violently impact the bottom of the shaft, making the cable less prone to damage and extending its service life.

[0019] Optionally, the clamping part includes a linkage rod and a clamping rod. One end of the linkage rod is rotatably connected to the support rod, and the other end is rotatably connected to the clamping rod. The side wall of the clamping rod is rotatably connected to the support block. When the linkage rod rotates, it drives the end of the clamping rod away from the linkage rod to move towards or away from the cable.

[0020] By adopting the above technical solution, when the support rod drives the two linkage rods to move towards the ground simultaneously, the end of the linkage rod away from the ground rotates about the connection point between the linkage rod and the support rod, and is close to the central axis of the support rod. This causes the end of the clamping rod close to the support rod to rotate about the connection point between the clamping rod and the support block, and is close to the extension line of the central axis of the support rod. As a result, the ends of the two clamping rods away from the support rod move away from the cable until the two clamping rods separate from the side wall of the cable, that is, the two clamping rods are in an open state, which facilitates the movement of the cable. When the support rod drives the two linkage rods to move simultaneously away from the ground, the end of the linkage rod away from the ground moves away from the central axis of the support rod with the end of the linkage rod closer to the ground as the axis. This causes the end of the clamping rod away from the ground to move closer to the cable with the connection between the clamping rod and the support block as the axis, until the two clamping rods abut against the side wall of the cable. The two clamping rods simultaneously apply a squeezing force to the side wall of the cable towards the center of the cable, creating a relative force between the two clamping rods. This fixes the cable to the clamping rods, preventing the cable from moving. Consequently, the cable will not move rapidly towards the bottom of the shaft under the action of gravity, and the cable end will not violently impact the bottom of the shaft, making the cable end less prone to damage and extending the cable's service life.

[0021] Optionally, a protective element is provided on the side of the clamping rod near the central axis of the support rod.

[0022] By adopting the above technical solution, when the clamping rod moves towards the cable until the protective component abuts against the side wall of the cable, and the two clamping rods simultaneously apply a squeezing force towards the center of the cable, a relative force is generated between the two protective components, thereby fixing the cable to the clamping rod. The protective component plays a protective role, preventing the clamping rod from scratching the side wall of the cable and extending the service life of the cable.

[0023] Optionally, the side wall of the support block is provided with a guide groove for the push rod to pass through. The guide groove is provided along the length direction of the mounting frame, and the push rod is inserted into the guide groove and slides in the guide groove.

[0024] By adopting the above technical solution, when the propulsion drive unit moves the propulsion rod, the inner wall of the guide groove abuts against the side wall of the propulsion rod, which restricts the propulsion rod so that it can only move along the length direction of the guide groove. This ensures that the propulsion rod always moves horizontally and is not prone to deflection, thereby increasing the stability of the propulsion rod's movement.

[0025] Secondly, the construction method for laying cables using a cable laying device provided in this application adopts the following technical solution:

[0026] S1. Move the mounting bracket to the opening of the shaft, and use the push drive to drive the push rod to move back and forth along the length of the mounting bracket. This causes the moving rod to drive the fixed rod to rotate in one direction in the push ring groove, so that the cam protrusion continuously slides against the side wall of the cable, driving the cable to move closer to the shaft.

[0027] S2. When the cam's protrusion separates from the cable's side wall, a baffle near the cable reel abuts against the mounting rod, causing the mounting rod to move away from the cable reel. This causes the connecting rod to rotate, which in turn causes the support rod to move away from the ground. This causes the linkage rod to rotate, which in turn causes the clamping rod to move away from the support rod towards the cable until it abuts against the cable's side wall, clamping the cable and preventing it from rapidly descending under gravity.

[0028] S3. As the cam's protrusion gradually moves closer to the cable, a baffle away from the cable reel abuts against the mounting rod, causing the mounting rod to move closer to the cable reel. This causes the connecting rod to reverse, moving the clamping rod away from the support rod away from the cable until it separates from the cable's sidewall. At this point, the cam's protrusion abuts against the cable's sidewall, ensuring that the clamping rod does not interfere with the cable's movement, thus facilitating the cable's movement.

[0029] S4. When the cable moves to the shaft, the bottom of the cable loses support. Under the action of gravity, the cable bends and moves downward. The cam continues to drive the cable to move, so that the end of the cable extends to the bottom of the shaft, completing the laying of the cable in the shaft.

[0030] By adopting the above technical solution, the mounting frame is moved to the opening of the shaft. The propulsion drive unit moves the propulsion rod along the length of the mounting frame towards the cable reel. This causes the moving rod to move the fixed rod along the trajectory of the propulsion groove away from the cable. Consequently, the cam's protrusion gradually moves towards the cable. A baffle away from the cable reel abuts against the mounting rod, moving the mounting rod towards the cable reel. This causes the connecting rod to rotate, moving the end of the clamping rod away from the support rod away from the cable until it separates from the cable's sidewall. At this point, the cam's protrusion abuts against the cable's sidewall, ensuring the clamping rod does not interfere with the cable's movement, facilitating cable movement. When the cable reaches the shaft, its bottom loses support and, under gravity, bends downwards. The cam continues to move the cable, causing the cable end to extend towards the bottom of the shaft.

[0031] Next, the drive mechanism is activated, moving the push rod away from the cable reel. This causes the moving rod to move the fixed rod along the track of the push ring groove towards the cable, gradually separating the cam's protrusion from the cable's sidewall. A baffle near the cable reel abuts against the mounting rod, moving the mounting rod away from the cable reel. This causes the connecting rod to reverse, moving the support rod away from the ground. The linkage rod then rotates, moving the clamping rod away from the support rod towards the cable until it abuts against the cable's sidewall, clamping the cable. This prevents the cable from rapidly descending under gravity, thus reducing the risk of a violent impact with the bottom of the shaft and extending the cable's lifespan.

[0032] In summary, this application includes at least one of the following beneficial effects:

[0033] 1. Unscrew one end of the cable from the cable reel and continue rotating the reel, allowing the cable to pass through the fixing component and be placed at the advancing component. Activate the advancing component, causing it to rotate, which in turn rotates the connecting component, moving the fixing component away from the ground until it abuts against the side wall of the cable. This creates a mutual compressive force on the cable's side wall, securing the cable to the mounting frame. Next, move the mounting frame to the shaft opening and rotate the advancing component, causing the connecting component to reverse, moving the fixing component closer to the ground until it abuts against the side wall of the cable. At this point, the fixing component is completely separated from the cable's side wall. The advancing component continues to rotate, sliding against the cable's side wall, transporting the cable towards the bottom of the shaft, thus laying the cable within the shaft. Only with the advancement component and the separation of the fixing component can the cable move, preventing it from rapidly descending under gravity. This avoids a violent impact when the cable reaches the bottom of the shaft, minimizing damage to the cable end and increasing its lifespan.

[0034] 2. When the mounting frame moves to the opening of the shaft, the drive unit is activated, causing it to move the propulsion unit away from the cable reel, thus rotating the propulsion unit. When the propulsion unit comes into contact with the side wall of the cable, it continues to move, causing the propulsion unit and the cable to slide against each other, pushing the cable away from the cable reel. When the end of the cable away from the cable reel moves to the opening of the shaft, it moves vertically downward under the action of gravity, thus completing the cable laying within the shaft.

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] This application discloses a cable laying device. (Refer to...) Figure 1 and Figure 2 The cable laying device includes a mounting frame 1. Four rollers are rotatably connected to the bottom of the mounting frame 1, and the four rollers are symmetrical in pairs. A cable reel 2 is rotatably connected to the mounting frame 1. Several sliding rollers 11 are rotatably connected to the side wall of the mounting frame 1. The sliding rollers 11 are perpendicular to the length direction of the mounting frame 1 and are evenly distributed along the length direction of the mounting frame 1. One end of the cable rotates off the cable reel 2 and abuts against the side wall of the sliding roller. When the cable moves along the length direction of the mounting frame 1, the cable slides against the side wall of the sliding roller 11, causing the sliding roller 11 to rotate. This results in rolling friction during the cable movement, which is less than direct sliding against the mounting frame 1. This makes the cable side wall less prone to damage and extends the service life of the cable.

[0045] Reference Figure 1 and Figure 2 The mounting frame 1 is provided with a drive mechanism 3, which includes a propulsion assembly 31. The propulsion assembly 31 includes a drive part 311 and two propulsion parts 312. The drive part 311 includes a propulsion drive component 3111 and a propulsion rod 3112. In this embodiment, the propulsion drive component 3111 is an electric push rod. The propulsion drive component 3111 is fixedly mounted on the mounting frame 1 by bolts. The output end of the propulsion drive component 3111 is glued to the propulsion rod 3112 for driving the propulsion rod 3112 to move along the length direction of the mounting frame 1.

[0046] When the mounting frame 1 moves to the opening of the shaft, the push drive 3111 is activated to extend and retract, pushing the push rod 3112 along the length of the mounting frame 1 towards or away from the cable reel 2. This causes the cable to move along the length of the mounting frame 1. When one end of the cable moves to the opening of the shaft, the bottom of the cable loses support and, under the action of gravity, bends downward and extends towards the bottom of the shaft, thus enabling the cable to be laid in the shaft.

[0047] Reference Figure 1 and Figure 2 A support block 8 is welded and fixed to the mounting frame 1. A guide groove 80 is formed through the side wall of the support block 8, and the guide groove 80 is arranged along the length direction of the mounting frame 1. The push rod 3112 passes through the guide groove 80 and slides in the guide groove 80. The inner wall of the guide groove 80 abuts against the side wall of the push rod 3112, which restricts the push rod 3112 so that it can only move along the length direction of the guide groove 80. This ensures that the push rod 3112 always moves horizontally and is not prone to deflection, thereby increasing the stability of the push rod 3112's movement.

[0048] Reference Figure 2 and Figure 3 The two propulsion units 312 are symmetrical about the central axis of the mounting frame 1. Each propulsion unit 312 includes a moving rod 3121, a fixed rod 3122, and a cam 3123. The moving rod 3121 is horizontally arranged, with one end rotatably connected to the drive unit 311 and the other end rotatably connected to one end of the fixed rod 3122. The fixed rod 3122 is vertically arranged, with the end of the fixed rod 3122 away from the moving rod 3121 welded and fixed to the side wall of the cam 3123. The fixed rod 3122 is located on the cam 3123. In a non-axial position, cam 3123 is rotatably connected to mounting bracket 1. Two push plates 5 are welded and fixed on mounting bracket 1. Push plates 5 correspond one-to-one with cam 3123 and are parallel to cam 3123. The push plates 5 and cam 3123 are coaxial and rotatably connected. Push plates 5 have push ring grooves 50 with the central axis of push plates 5 as the axis. Fixed rod 3122 passes through push ring grooves 50 and slides in push ring grooves 50 to drive cam 3123 to rotate.

[0049] The drive unit 3111 is activated, which drives the push rod 3112 to move closer to the cable reel 2. This causes both moving rods 3121 to move simultaneously closer to the cable reel 2. The inner wall of the push ring groove 50 abuts against the side wall of the fixed rod 3122, which guides the fixed rod 3122 so that it can only move along the trajectory of the push ring groove 50. This causes the moving rod 3121 to rotate about the end of the push rod 3112, which in turn causes the fixed rod 3122 to move away from the cable along the trajectory of the push ring groove 50. At the same time, it drives the two cams 3123 to rotate synchronously until the fixed rod 3122 moves to the end of the push ring groove 50 closer to the cable reel 2. At this time, the outer edge of the protrusion of the cam 3123 abuts against the side wall of the cable. Then, the push drive 3111 drives the push rod 3112 to move away from the cable reel 2, so that the two moving rods 3121 move away from the cable reel 2 at the same time, and the fixed rod 3122 moves along the trajectory of the push ring groove 50 towards the cable. Thus, the protrusion of the cam 3123 slides against the side wall of the cable, pushing the cable away from the cable reel 2, thereby realizing the cable unloading.

[0050] When the cable moves to the opening of the shaft, under the action of gravity, the end of the cable is inserted into the shaft and moves vertically downward, realizing the laying of the cable in the shaft. The cable is driven to move by the propulsion unit 312. Compared with the cable moving downward by gravity, the cable is less likely to have a violent impact with the bottom of the shaft, thus making the cable less prone to damage and extending the service life of the cable.

[0051] Reference Figure 2 and Figure 3 A limiting component 10 is provided in the propulsion ring groove 50. The limiting component 10 includes two limiting blocks 101 and two limiting springs 102. Two limiting grooves 51 are formed in the propulsion ring groove 50. The two limiting grooves 51 are symmetrical about a horizontal line passing through the center of the propulsion plate 5. The line connecting the two limiting grooves 51 is not perpendicular to the length direction of the mounting frame 1. One limiting groove 51 near the cable reel 2 is located on the side of the propulsion ring groove 50 away from the central axis of the mounting frame 1, while the other limiting groove 51 away from the cable reel 2 is located on the side of the propulsion ring groove 50 away from the cable reel. One end of 2 is close to the central axis of the mounting frame 1. The limiting groove 51 corresponds to the limiting block 101. The limiting block 101 is inserted into the limiting groove 51. The side of the limiting block 101 away from the center of the push plate 5 is welded and fixed to one end of the limiting spring 102, and the other end is welded and fixed to the side of the limiting groove 51 away from the center of the push plate 5. A guide surface 1010 is cut on the side of the limiting block 101 close to the cable reel 2 away from the central axis of the mounting frame 1. A guide surface 1010 is cut on the side of the limiting block 101 away from the cable reel 2 close to the central axis of the mounting frame 1.

[0052] When the push rod 3112 drives the fixed rod 3122 to move closer to the cable reel 2, and the fixed rod 3122 abuts against the guide surface 1010, the guide surface 1010 acts as a guide, squeezing the limiting block 101 closer to the cable reel 2 and compressing the limiting spring 102, so that the limiting block 101 is completely housed in the limiting groove 51. This causes the fixed rod 3122 to move to the end of the push ring groove 50 closer to the cable reel 2. At this time, the limiting block 101 loses its squeezing force, and the limiting spring 102 returns to its original deformation, so that the side of the limiting block 101 closer to the cable abuts against the side of the fixed rod 3122 away from the cable. When the push rod 3112 drives the fixed rod 3122 to move away from the cable reel 2, the limiting block 101 acts as a limit, so that the fixed rod 3122 will not return along the original path, but will move closer to the cable along the trajectory of the push ring groove 50.

[0053] When the fixed rod 3122 moves to a limiting block 101 away from the cable reel 2, it abuts against the guide surface 1010, pressing the limiting block 101 away from the cable reel 2. This facilitates the fixed rod 3122 moving to the end of the push ring groove 50 away from the cable reel 2. At this time, the side of the fixed rod 3122 closer to the cable abuts against the side of the limiting block 101 away from the cable, thus limiting its movement. This ensures that when the push rod 3112 drives the fixed rod 3122 to move closer to the cable reel 2, the fixed rod 3122 will move along the trajectory of the push ring groove 50 away from the cable. This ensures that when the push rod 3112 moves along the length of the mounting frame 1, the fixed rod 3122 drives the cam 3123 to always move in a circular motion in one direction without reversing, i.e., it will not move the cable closer to the cable reel 2, thus realizing the cable transport.

[0054] Reference Figure 4 and Figure 5 The drive assembly also includes a fixing assembly 32 for clamping the cable. The push rod 3112 is connected to the fixing assembly 32 through the connecting assembly 4. The connecting assembly 4 includes a mounting rod 41, a connecting rod 42, and two baffles 43. The side of the two baffles 43 away from the ground is welded and fixed to the push rod 3112 and is arranged along the length direction of the mounting frame 1. The mounting rod 41 is vertically arranged, and one end of the mounting rod 41 is located between the two baffles 43. The other end is integrally formed with the connecting rod 42. The mounting rod 41 is perpendicular to the connecting rod 42. The connecting rod 42 is parallel to the length direction of the mounting frame 1. A mounting seat 6 is welded and fixed on the mounting frame 1. The connecting rod 42 passes through the mounting seat 6, and the middle part of the connecting rod 42 is rotatably connected to the mounting seat 6 through a rotating shaft. Support springs 7 are welded and fixed at both ends of the connecting rod 42. The end of the support spring 7 away from the connecting rod 42 is welded and fixed to the mounting frame 1.

[0055] Reference Figure 4 and Figure 5The drive unit 3111 drives the push rod 3112 to move closer to the cable reel 2 until a baffle 43 away from the cable reel 2 abuts against the mounting rod 41, and pushes the mounting rod 41 closer to the cable reel 2. This causes the connecting rod 42 to rotate about the connection between the connecting rod 42 and the mounting base 6, thereby compressing the support spring 7 at the end of the connecting rod 42 closer to the cable reel 2 and driving the fixing component 32 to move closer to the ground. This causes the fixing component 32 to move away from the cable, while the fixing rod 3122 moves away from the cable along the trajectory of the push ring groove 50.

[0056] When the fixed rod 3122 drives the protrusion of the cam 3123 to abut against the side wall of the cable, the fixed assembly 32 is completely separated from the side wall of the cable. Then, the push drive 3111 drives the push rod 3112 to move away from the cable reel 2 until a baffle 43 near the cable reel 2 abuts against the mounting rod 41, and drives the mounting rod 41 to move away from the cable reel 2, causing the connecting rod 42 to rotate. The end of the connecting rod 42 away from the cable reel 2 compresses the support spring 7, and drives the fixed assembly 32 to move away from the ground, so that the fixed assembly 32 moves towards the cable. At the same time, the fixed rod 3122 drives the protrusion of the cam 3123 to move towards the cable, so that the protrusion of the cam 3123 slides against the side wall of the cable, and drives the cable to move away from the cable reel 2 along the length of the mounting frame 1.

[0057] After the protrusion of the cam 3123 is completely separated from the side wall of the cable, the fixing component 32 abuts against the side wall of the cable and applies mutual squeezing force to the side wall of the cable, fixing the cable on the mounting bracket 1 so that the cable will not continue to move under the action of gravity, thereby preventing the end of the cable from violently impacting the bottom of the shaft, making the cable less prone to damage and extending the service life of the cable.

[0058] Reference Figure 5 and Figure 6 The fixing component 32 includes a support rod 321 and two clamping parts 322. The support rod 321 is vertically arranged, and one end of the support rod 321 is adapted to be inserted into the support block 8 and slides in the support block 8. The other end is rotatably connected to the end of the connecting rod 42 away from the mounting rod 41. The mounting base 6 is located between the mounting rod 41 and the support rod 321. The two clamping parts 322 are symmetrical about the central axis of the cable and are rotatably connected to the support block 8.

[0059] Reference Figure 6 and Figure 7The clamping part 322 includes a linkage rod 3221 and a clamping rod 3222. One end of the linkage rod 3221 is rotatably connected to the support rod 321, and the other end is rotatably connected to the clamping rod 3222. The side wall of the clamping rod 3222 is rotatably connected to the support block 8. When the linkage rod 3221 rotates, it drives the end of the clamping rod 3222 away from the linkage rod 3221 to move towards or away from the cable.

[0060] When the support rod 321 drives the two linkage rods 3221 to move towards the ground simultaneously, the end of the linkage rod 3221 away from the ground rotates about the connection point between the linkage rod 3221 and the support rod 321, and moves towards the central axis of the support rod 321. This causes the end of the clamping rod 3222 near the support rod 321 to rotate about the connection point between the clamping rod 3222 and the support block 8, and move towards the extension of the central axis of the support rod 321. This causes the ends of the two clamping rods 3222 away from the support rod 321 to move away from the cable until the two clamping rods 3222 separate from the side wall of the cable, i.e., the two clamping rods 3222 are in an open state, which facilitates the movement of the cable.

[0061] When the support rod 321 drives the two linkage rods 3221 to move away from the ground simultaneously, the end of the linkage rod 3221 away from the ground moves away from the central axis of the support rod 321 with the end of the linkage rod 3221 near the ground as the axis. This causes the end of the clamping rod 3222 away from the ground to move towards the cable with the connection between the clamping rod 3222 and the support block 8 as the axis, until the two clamping rods 3222 abut against the side wall of the cable. The two clamping rods 3222 simultaneously apply a squeezing force to the side wall of the cable towards the center of the cable, so that a relative force is generated between the two clamping rods 3222. This fixes the cable to the clamping rods 3222, meaning the cable will not move. This prevents the cable from moving rapidly towards the bottom of the shaft under the action of gravity, thus preventing the cable end from violently impacting the bottom of the shaft, making the cable end less prone to damage and extending the cable's service life.

[0062] Reference Figure 1 and Figure 7 A positioning rod 12 is welded and fixed to the mounting frame 1. The positioning rod 12 is vertically positioned, and a pressure plate 13 is welded and fixed to the end of the positioning rod 12 away from the ground. The pressure plate 13 is located between the clamping rod 3222 and the cable reel 2, and is directly above the cable. The side wall of the cable abuts against the side of the pressure plate 13 closest to the ground, so that the cable can only move within the area between the pressure plate 13 and the mounting frame 1. Under the action of the pressure plate 13 and the weight of the cable itself, the cable rotating off the cable reel 2 and moving on the mounting frame 1 always passes between the two clamping rods 3222, thereby causing the clamping rods 3222 to move closer to the cable and accurately abut against the side wall of the cable.

[0063] Reference Figure 7 A protective component 9 is provided on the side of the clamping rod 3222 near the central axis of the support rod 321. The protective component 9 includes a rubber pad 91 and a clamping spring 92. The rubber pad 91 is glued to the clamping rod 3222. A cavity 910 is opened in the rubber pad 91. The clamping spring 92 is located in the cavity 910. Both ends of the clamping spring 92 are welded and fixed to the inner wall of the cavity 910, which is used to push the rubber pad 91 towards the central axis of the cable.

[0064] As the clamping rods 3222 move toward the cable, until the rubber pads 91 abut against the sidewall of the cable, and both clamping rods 3222 simultaneously apply a force pressing toward the center of the cable, a relative force is generated between the two rubber pads 91, thereby fixing the cable to the clamping rods 3222. The rubber pads 91 play a protective role, preventing the clamping rods 3222 from scratching the sidewall of the cable and extending the service life of the cable.

[0065] While the rubber pad 91 is squeezing the cable, the clamping spring 92 also applies a force that squeezes the rubber pad 91 toward the center of the cable, increasing the squeezing force applied by the clamping rod 3222 to the side wall of the cable. This increases the relative force between the two clamping rods 3222, thereby improving the stability of the two clamping rods 3222 in clamping the cable.

[0066] The implementation principle of the cable laying device in this application embodiment is as follows: the mounting frame 1 is moved to the opening of the shaft, and the push drive 3111 drives the push rod 3112 to move along the length of the mounting frame 1 towards the cable reel 2. This causes the moving rod 3121 to drive the fixed rod 3122 to move away from the cable along the trajectory of the push ring groove 50. As a result, the protrusion of the cam 3123 gradually moves towards the cable. A baffle 43 away from the cable reel 2 abuts against the mounting rod 41 and drives the mounting rod 41 towards the cable reel 2. The movement of the cable reel 2 causes the connecting rod 42 to rotate, which in turn moves the end of the clamping rod 3222 away from the support rod 321 away from the cable until it separates from the side wall of the cable. At this point, the protrusion of the cam 3123 abuts against the side wall of the cable, thus preventing the clamping rod 3222 from interfering with the movement of the cable and facilitating its movement. When the cable reaches the shaft, its bottom loses support and, under the influence of gravity, bends and moves downward. The cam 3123 continues to move the cable, causing the cable end to extend towards the bottom of the shaft.

[0067] Next, the drive unit 3111 is activated, which drives the push rod 3112 to move away from the cable reel 2. This causes the moving rod 3121 to drive the fixed rod 3122 to move along the trajectory of the push ring groove 50 towards the cable. As a result, the protrusion of the cam 3123 gradually separates from the side wall of the cable. A baffle 43 near the cable reel 2 abuts against the mounting rod 41 and drives the mounting rod 41 to move away from the cable reel 2. This causes the connecting rod 42 to reverse, driving the support rod 321 to move away from the ground. This causes the linkage rod 3221 to rotate, driving the clamping rod 3222 to move towards the cable from the end away from the support rod 321 until it abuts against the side wall of the cable, clamping the cable. This prevents the cable from rapidly descending under the action of gravity, thus making it less likely for the cable to violently impact the bottom of the shaft, thereby reducing the cable's damage and extending its service life.

[0068] The embodiments also disclose a construction method for laying cables using a cable laying device.

[0069] Includes the following steps:

[0070] S1. Move the mounting frame 1 to the opening of the shaft. Use the push drive 3111 to drive the push rod 3112 to move back and forth along the length of the mounting frame 1. This causes the moving rod 3121 to drive the fixed rod 3122 to rotate in one direction in the push ring groove 50. This causes the protrusion of the cam 3123 to continuously slide against the side wall of the cable, driving the cable to move closer to the shaft.

[0071] S2. When the protrusion of the cam 3123 separates from the side wall of the cable, a baffle 43 near the cable reel 2 abuts against the mounting rod 41 and drives the mounting rod 41 to move away from the cable reel 2, causing the connecting rod 42 to rotate, driving the support rod 321 to move away from the ground, causing the linkage rod 3221 to rotate, driving the clamping rod 3222 to move away from the support rod 321 towards the cable until it abuts against the side wall of the cable, clamping the cable so that the cable will not move down rapidly under the action of gravity.

[0072] S3. When the protrusion of cam 3123 gradually moves towards the cable, a baffle 43 away from the cable reel 2 abuts against the mounting rod 41, and drives the mounting rod 41 to move towards the cable reel 2, causing the connecting rod 42 to reverse, and driving the end of the clamping rod 3222 away from the support rod 321 to move away from the cable until it separates from the side wall of the cable. At this time, the protrusion of cam 3123 abuts against the side wall of the cable, so that the clamping rod 3222 will not interfere with the movement of the cable, which facilitates the movement of the cable.

[0073] S4. When the cable moves to the shaft, the bottom of the cable loses support. Under the action of gravity, the cable bends and moves downward. Cam 3123 continues to drive the cable to move, so that the end of the cable extends to the bottom of the shaft, completing the laying of the cable in the shaft.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
