Description

Technical Field

[0001] The present invention relates to the technical field of power grid line laying construction equipment, and specifically relates to a power grid line laying construction device and a construction method. Background Art

[0002] During the laying process of power grid lines, workers need to first unwind the cable wound on the cable reel, and then they can lay the cable. With the development of science and technology, cable conveyors are often used to replace manual clamping and traction of the cable to unwind the cable from the cable reel and convey the cable.

[0003] The existing power grid line laying devices can basically meet people's usage requirements. However, when the existing power grid line laying devices are used for laying on a bend, since the inner and outer radii of the bend are different, the laying lengths of the power grid lines on the inner side and the outer side of the bend are different during the laying of the power grid lines. Moreover, the existing laying devices lack a device for controlling the cable outlet speed, resulting in disorder of several power grid lines during the bend laying. Summary of the Invention

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a power grid line laying construction device and a construction method, including a laying platform.

A moving rod is fixedly connected directly above the end of the sliding plate away from the sliding column. A rotating shaft is rotatably connected to the side wall of the moving rod. The rotating shaft is slidably connected in the chute of the fixing frame. An adjusting pulley is fixedly connected to the end of the rotating shaft away from the moving rod.

[0008] Furthermore, the laying mechanism further includes a compression spring sleeved on the sliding column. An auxiliary plate is fixedly connected to the bottom of the laying platform. Several laying electric rods are fixedly connected to the bottom of the auxiliary plate. A lower pressing plate is fixedly connected to the end of the laying electric rod away from the auxiliary plate.

[0009] Furthermore, the laying mechanism further includes a laying telescopic rod fixedly connected to the bottom of the lower pressing plate. A laying plate is fixedly connected to the end of the laying telescopic rod away from the lower pressing plate. Several limiting plates are fixedly connected to the bottom of the laying plate. Several locking pulleys are rotatably connected in the limiting plates. A laying pulley is rotatably connected to the end of the limiting plate away from the locking pulley.

[0010] Furthermore, a steering mechanism is arranged at the bottom of the laying platform. The steering mechanism includes a steering electric rod fixedly connected to the bottom of the sliding plate at the end away from the pushing frame. A steering tooth plate is fixedly connected to the end of the steering electric rod away from the sliding plate. Steering gears are fixedly connected to both rotating columns I at the end away from the pushing frame. The teeth of the steering tooth plate are meshed with the teeth of the steering gears. A fixed frame is fixedly connected to the sliding plate on the side away from the pushing frame. A sliding rod I is fixedly connected to the side wall of the fixed frame. The steering tooth plate is slidably connected to the middle of the sliding rod I.

[0011] Furthermore, a wire outlet control mechanism is arranged directly below the laying platform. The wire outlet control mechanism includes a rack fixedly connected to the top of the steering tooth plate. A threaded rod is rotatably connected to the end of the fixed frame away from the sliding plate. An adjusting gear is fixedly connected to the end of the threaded rod away from the fixed frame. The adjusting gear is meshed with the rack.

[0012] Furthermore, the wire outlet control mechanism further includes a sliding block II rotatably connected to the middle of the threaded rod. A sliding rod II is fixedly connected to the end of the fixed frame away from the sliding plate. The sliding block II is slidably connected to the middle of the sliding rod II. A limiting rod is fixedly connected to the top of the sliding block II. A linkage rod II is slidably connected to the limiting rod.

[0013] Further, the wire outlet control mechanism further includes a control turntable fixedly connected to the second rotating column. A bidirectional telescopic rod slidably penetrates through the fixed disk. The bottom of the bidirectional telescopic rod is fixedly connected to a driving column. One end of the driving column away from the bidirectional telescopic rod is rotatably connected to the second linkage rod. Pressure springs are sleeved on both ends of the bidirectional telescopic rod. Friction plates are fixedly connected to both ends of the bidirectional telescopic rod. The friction plates are pressed against one side of the control turntable.

[0014] The construction method of the power grid line laying construction device includes the following steps: Step 1: Fix the power grid wire. At this time, insert the wire reel with the power grid wire along the second rotating column. At this time, the wire reel is pressed against several fastening rods on the second rotating column. The fastening rods are pressed to drive two sliding blocks one inside the second rotating column to move away from each other along the inner cavity of the second rotating column. At this time, the sliding block one pulls the tension spring. The tension of the tension spring increases when it is stretched. At this time, the tension of the tension spring on the fastening rod at one end of the sliding block one increases. Such a setting is beneficial to increasing the clamping force of the fastening rod on the wire reel, so that the wire reel is fixed on the second rotating column and ensures that the wire reel remains stable during rotation. Step 2: Lay the power grid wire. When pushing the laying platform, the lower pressing plate at the bottom is pushed downward by the laying electric rod. The downward movement of the lower pressing plate drives the locking pulley and the laying pulley on the limiting plate at the bottom of the laying plate to be pressed against the bottom of the laying tunnel. At this time, the laying telescopic rod is compressed and contracted. Such a setting is beneficial to ensuring that when the device is jolted, the locking pulley and the laying pulley are separated from the bottom of the laying tunnel. When the device vibrates up and down due to jolting, the laying electric rod retracts and extends with the vibration amplitude to ensure that the locking pulley and the laying pulley on the limiting plate are always in contact with the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid wire. Step 3: Adjust the tension of the power grid wire. When the moving wheel travels to a bumpy section, several sliding columns at the bottom of the laying platform slide up and down along the sliding plate. When the laying platform moves downward, the laying electric rod contracts. At this time, the travel of the power grid wire is shortened, but the length of the power grid wire remains unchanged. This will cause the tension of the power grid wire to decrease. By setting the adjusting pulley, when the laying platform moves downward, the rotating shaft on the adjusting pulley slides upward along the chute on the fixed frame. At this time, the adjusting pulley drives the power grid wire to be stretched upward. Such a setting is beneficial to increasing the tension of the power grid wire, thereby preventing the power grid wire from falling off the device. Step 4: Adjust the wire outlet speed of the power grid wire according to the curve. The rack on the steering tooth plate drives the threaded rod on the adjusting gear to rotate. The rotation of the threaded rod drives the limiting rod on the top of the second sliding block to move along the second sliding rod towards the end away from the adjusting gear. The limiting rod drives the bidirectional telescopic rod on the driving column at one end of the second linkage rod to slide along the fixed disk towards the inner side of the curve. At this time, the extrusion force between the friction plate near the inner side of the curve of the bidirectional telescopic rod and the control turntable increases, and the extrusion force between the friction plate near the outer side of the curve of the bidirectional telescopic rod and the control turntable decreases. This setting is beneficial to increasing the rotation resistance of the wire winding wheel on the second rotating column on the inner side of the curve, thereby slowing down the wire outlet speed of the wire winding wheel on the inner side of the curve, so as to ensure that the power grid wire can automatically adjust the wire outlet speed of different curve radii during curve laying and improve the quality of power grid wire curve laying.

[0015] The present invention has the following beneficial effects: (1). In the present invention, by setting a steering mechanism, when laying a curve, by adjusting the steering electric rod, the steering electric rod drives the steering tooth plate to move. The movement of the steering tooth plate drives the steering gear to rotate. The rotation of the steering gear drives the moving wheel at the bottom of the first rotating column to rotate, thereby realizing the steering function of the device; in addition, when the device needs to turn, the steering electric rod extends to drive the steering gear at one end of the steering tooth plate to rotate clockwise. At this time, the rack on the steering tooth plate drives the threaded rod on the adjusting gear to rotate. The rotation of the threaded rod drives the limiting rod on the top of the second sliding block to move along the second sliding rod towards the end away from the adjusting gear. The limiting rod drives the bidirectional telescopic rod on the driving column at one end of the second linkage rod to slide along the fixed disk towards the inner side of the curve. At this time, the extrusion force between the friction plate near the inner side of the curve of the bidirectional telescopic rod and the control turntable increases, and the extrusion force between the friction plate near the outer side of the curve of the bidirectional telescopic rod and the control turntable decreases. This setting is beneficial to increasing the rotation resistance of the wire winding wheel on the second rotating column on the inner side of the curve, thereby slowing down the wire outlet speed of the wire winding wheel on the inner side of the curve, so as to ensure that the power grid wire can automatically adjust the wire outlet speed of different curve radii during curve laying and improve the quality of power grid wire curve laying.

[0016] (2). In the present invention, when using the power grid wire laying construction device, first install the wire winding wheel on the second rotating column. At this time, insert the wire winding wheel with the power grid wire along the second rotating column onto the second rotating column. At this time, the wire winding wheel is pressed against several fastening rods on the second rotating column. The fastening rods are pressed to drive two sliding blocks one inside the second rotating column to move away from each other along the inner cavity of the second rotating column. At this time, the sliding block one pulls the tension spring. The tension of the tension spring increases due to being stretched. At this time, the pulling force of the tension spring on the fastening rod at one end of the sliding block one increases. This setting is beneficial to increasing the clamping force of the fastening rod on the wire winding wheel, so as to fix the wire winding wheel on the second rotating column and ensure the stability of the wire winding wheel during rotation.

[0017] (3) In the present invention, by providing a laying mechanism, when the wire reel is installed on the second rotating column, one end of the power grid wire on the wire reel passes through the adjusting pulley, the limiting pulley, the locking pulley, and the laying pulley respectively, and then the tail of the power grid wire is fixed to the bottom of the laying tunnel. At this time, several power grid wires are arranged on the laying mechanism. Such an arrangement is conducive to separating several power grid wires, thereby avoiding interference between the power grid wires and improving the laying quality of the power grid wires. When the laying platform is pushed, the lower pressing plate at the bottom is pushed downward by the laying electric rod. The downward movement of the lower pressing plate drives the locking pulley and the laying pulley on the limiting plate at the bottom of the laying plate to be pressed against the bottom of the laying tunnel. At this time, the laying telescopic rod is compressed and contracted. Such an arrangement is conducive to ensuring that when the device is jolted, the locking pulley and the laying pulley are separated from the bottom of the laying tunnel. When the device vibrates up and down due to jolting, the laying electric rod retracts and extends with the vibration amplitude to ensure that the locking pulley and the laying pulley on the limiting plate are always in contact with the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid wire.

[0018] (4) In the present invention, by providing a laying mechanism, when the moving wheels travel to a bumpy section, several sliding columns at the bottom of the laying platform slide up and down along the sliding plate. When the laying platform moves downward, the laying electric rod contracts. At this time, the travel of the power grid wire is shortened, but the length of the power grid wire remains unchanged. This will cause the tension of the power grid wire to decrease. By providing an adjusting pulley, when the laying platform moves downward, the rotating shaft on the adjusting pulley slides upward along the sliding groove on the fixed frame. At this time, the adjusting pulley drives the power grid wire to be stretched upward. Such an arrangement is conducive to increasing the tension of the power grid wire, thereby avoiding the power grid wire falling off the device.

[0019] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Example 1, please refer to Figures 1-4As shown in the figure, the present invention is a power grid line laying construction device and construction method, including a laying platform 1. A pushing frame 11 is fixedly connected to the top of the left end of the laying platform 1. A plurality of sliding columns 12 are fixedly connected to the bottom of the laying platform 1. The end of the sliding column 12 away from the laying platform 1 is slidably connected to a sliding plate 13. The bottom of the end of the sliding plate 13 away from the sliding column 12 is rotatably connected to a first rotating column 14. The end of the first rotating column 14 away from the 1 sliding plate 13 is rotatably connected to a moving wheel 15. It further includes: An electric wire feeding mechanism 2, which includes a winding wheel 203, a fastening rod 207, a supporting component for supporting the winding wheel 203, and an extrusion component for fixing the winding wheel 203; The supporting component includes a fixed disk 201 fixedly connected above the laying platform 1. A second rotating column 202 is rotatably connected to both sides of the fixed disk 201. The winding wheel 203 is sleeved on the second rotating column 202.

[0025] The extrusion component includes a plurality of first sliding blocks 204 slidably connected to the central axis of the second rotating column 202. A tension spring 205 is fixedly connected between the plurality of first sliding blocks 204. A plurality of first linkage rods 206 are rotatably connected to the first sliding blocks 204. The end of the first linkage rod 206 away from the first sliding block 204 is fixedly connected to the fastening rod 207. The fastening rod 207 is in extrusion with the inner wall of the winding wheel 203. The function of this mechanism is that when using this power grid line laying construction device, first install the winding wheel 203 on the second rotating column 202. At this time, insert the winding wheel 203 with the power grid wire along the second rotating column 202 onto the second rotating column 202. At this time, the winding wheel 203 is in extrusion with a plurality of fastening rods 207 on the second rotating column 202. The fastening rod 207 is extruded to drive two first sliding blocks 204 inside the second rotating column 202 to move away from each other along the inner cavity of the second rotating column 202. At this time, the first sliding blocks 204 pull the tension spring 205, and the tension of the tension spring 205 increases due to the tensile force. At this time, the tension spring 205 increases the pulling force on the fastening rod 207 at one end of the first sliding block 204. Such a setting is beneficial to increasing the clamping force of the fastening rod 207 on the winding wheel 203, so as to fix the winding wheel 203 on the second rotating column 202 and ensure the stability of the winding wheel 203 during rotation.

[0026] There is a laying mechanism 3 directly below the laying platform 1. The laying mechanism 3 includes several fixing frames 301 fixedly connected to the bottom of the laying platform 1. There are sliding grooves formed on the fixing frames 301. Inside the fixing frames 301, there are limiting pulleys 302 rotatably connected. Directly above the end of the sliding plate 13 away from the sliding column 12, there is a moving rod 303 fixedly connected. On the side wall of the moving rod 303, there is a rotating shaft 304 rotatably connected. The rotating shaft 304 is slidably connected in the sliding grooves on the fixing frames 301. The end of the rotating shaft 304 away from the moving rod 303 is fixedly connected with an adjusting pulley 305.

[0027] The laying mechanism 3 further includes a compression spring 306 sleeved on the sliding column 12. At the bottom of the laying platform 1, there is an auxiliary plate 307 fixedly connected. At the bottom of the auxiliary plate 307, there are several laying electric rods 308 fixedly connected. The end of the laying electric rod 308 away from the auxiliary plate 307 is fixedly connected with a lower pressing plate 309.

[0028] The laying mechanism 3 further includes a laying telescopic rod 310 fixedly connected to the bottom of the lower pressing plate 309. The end of the laying telescopic rod 310 away from the lower pressing plate 309 is fixedly connected with a laying plate 311. At the bottom of the laying plate 311, there are several limiting plates 312 fixedly connected. Inside the limiting plates 312, there are several locking pulleys 313 rotatably connected. At the end of the limiting plate 312 away from the locking pulley 313, there is a laying pulley 314 rotatably connected. The function of this mechanism is that by setting the laying mechanism 3, when the wire reel 203 is installed on the rotating column two 202, one end of the power grid wire on the wire reel 203 is respectively passed through the adjusting pulley 305, the limiting pulley 302, the locking pulley 313, and the laying pulley 314, and then the tail of the power grid wire is fixed at the bottom of the laying tunnel; at this time, several power grid wires are arranged on the laying mechanism 3. Such a setting is beneficial to separately arrange several power grid wires, thereby avoiding mutual interference of the power grid wires and improving the laying quality of the power grid wires; when the laying platform 1 is pushed, the lower pressing plate 309 at the bottom is pushed downward by the laying electric rod 308. The downward movement of the lower pressing plate 309 drives the locking pulley 313 and the laying pulley 314 on the limiting plate 312 at the bottom of the laying plate 311 to be pressed against the bottom of the laying tunnel. At this time, the laying telescopic rod 310 is compressed and contracted. Such a setting is beneficial to ensure that when the device is jolted, the locking pulley 313 and the laying pulley 314 are separated from the bottom of the laying tunnel. When the device vibrates up and down due to jolting, the laying electric rod 308 contracts and extends with the vibration amplitude, ensuring that the locking pulley 313 and the laying pulley 314 on the limiting plate 312 are always in contact with the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid wires; Among them, when the moving wheels 15 travel on a bumpy road section, several sliding columns 12 at the bottom of the laying platform 1 slide up and down along the sliding plate 13. When the laying platform 1 moves downward, the laying electric rod 308 contracts. At this time, the travel of the power grid line is shortened, but the length of the power grid line remains unchanged, which will cause the tension of the power grid line to decrease. By setting the adjusting pulley 305, when the laying platform 1 moves downward, the rotating shaft 304 on the adjusting pulley 305 slides upward along the chute on the fixed frame 301. At this time, the adjusting pulley 305 drives the power grid line to be stretched upward. This setting is beneficial to increasing the tension of the power grid line, thereby preventing the power grid line from falling off the device.

[0029] Embodiment 2 is different from Embodiment 1 in that; as Figures 1-9 shown, a steering mechanism 4 is provided at the bottom of the laying platform 1. The steering mechanism 4 includes a steering electric rod 401 fixedly connected to the bottom of the sliding plate 13 at the end far from the pushing frame 11. One end of the steering electric rod 401 far from the sliding plate 13 is fixedly connected with a steering tooth plate 402. Steering gears 403 are fixedly connected to both rotating columns 14 at the end far from the pushing frame 11. The teeth of the steering tooth plate 402 mesh with the teeth of the steering gears 403. A fixed frame 404 is fixedly connected to the sliding plate 13 on the side far from the pushing frame 11. A sliding rod 405 is fixedly connected to the side wall of the fixed frame 404. The steering tooth plate 402 is slidably connected to the middle of the sliding rod 405. The function of this mechanism is to set the steering mechanism 4. When laying on a curve, by adjusting the steering electric rod 401, the steering electric rod 401 drives the steering tooth plate 402 to move. The movement of the steering tooth plate 402 drives the steering gear 403 to rotate. The rotation of the steering gear 403 drives the moving wheels 15 at the bottom of the rotating column 14 to rotate, thereby realizing the steering function of the device.

[0030] A wire outlet control mechanism 5 is provided directly below the laying platform 1. The wire outlet control mechanism 5 includes a rack 501 fixedly connected to the top of the steering tooth plate 402. A threaded rod 502 is rotatably connected to one end of the fixed frame 404 far from the sliding plate 13. One end of the threaded rod 502 far from the fixed frame 404 is fixedly connected with an adjusting gear 503. The adjusting gear 503 meshes with the rack 501.

[0031] The wire outlet control mechanism 5 further includes a sliding block 504 rotatably connected to the middle of the threaded rod 502. A sliding rod 505 is fixedly connected to one end of the fixed frame 404 far from the sliding plate 13. The sliding block 504 is slidably connected to the middle of the sliding rod 505. A limiting rod 506 is fixedly connected to the top of the sliding block 504. A linkage rod 507 is slidably connected to the limiting rod 506.

[0032] The wire outlet control mechanism 5 further includes a control turntable 509 fixedly connected to the second rotating column 202. A bidirectional telescopic rod 510 slidably penetrates through the fixed disk 201. The bottom of the bidirectional telescopic rod 510 is fixedly connected to a driving column 508. One end of the driving column 508 away from the bidirectional telescopic rod 510 is rotatably connected to the second linkage rod 507. Pressure springs 511 are sleeved on both ends of the bidirectional telescopic rod 510. Friction plates 512 are fixedly connected to both ends of the bidirectional telescopic rod 510. The friction plates 512 are pressed against one side of the control turntable 509. The function of this mechanism is that when the device needs to turn, the steering electric rod 401 extends to drive the steering gear 403 at one end of the steering tooth plate 402 to rotate clockwise. At this time, the rack 501 on the steering tooth plate 402 drives the threaded rod 502 on the adjusting gear 503 to rotate. The rotation of the threaded rod 502 drives the limiting rod 506 on the top of the second sliding block 504 to move along the second sliding rod 505 away from the adjusting gear 503. The limiting rod 506 drives the bidirectional telescopic rod 510 on the driving column 508 at one end of the second linkage rod 507 to slide along the fixed disk 201 towards the inner side of the bend. At this time, the extrusion force between the friction plate 512 close to the inner side of the bend of the bidirectional telescopic rod 510 and the control turntable 509 increases, and the extrusion force between the friction plate 512 close to the outer side of the bend of the bidirectional telescopic rod 510 and the control turntable 509 decreases. Such a setting is beneficial to increasing the rotation resistance of the wire winding wheel 203 on the second rotating column 202 on the inner side of the bend, thereby slowing down the wire outlet speed of the wire winding wheel 203 on the inner side of the bend, so as to ensure that the wire outlet speed of different bend radii can be automatically adjusted when the power grid wire is laid on the bend, and improve the quality of the power grid wire laying on the bend.

[0033] The construction method of the power grid line laying construction device includes the following steps: Step 1: Fix the power grid wire. At this time, insert the wire winding wheel 203 with the power grid wire along the second rotating column 202. At this time, the wire winding wheel 203 is pressed against several fastening rods 207 on the second rotating column 202. The fastening rods 207 are pressed to drive two sliding blocks 204 inside the second rotating column 202 to move away from each other along the inner cavity of the second rotating column 202. At this time, the sliding blocks 204 pull the tension spring 205, and the tensile force of the tension spring 205 increases due to the tension. At this time, the pulling force of the tension spring 205 on the fastening rod 207 at one end of the sliding block 204 increases. Such a setting is beneficial to increasing the clamping force of the fastening rod 207 on the wire winding wheel 203, so as to fix the wire winding wheel 203 on the second rotating column 202 and ensure the stability of the wire winding wheel 203 during rotation; Step 2: Lay the power grid line. When the laying platform 1 is pushed, the lower pressing plate 309 at the bottom is pushed downward by the laying electric rod 308. The downward movement of the lower pressing plate 309 drives the locking pulley 313 and the laying pulley 314 on the limiting plate 312 at the bottom of the laying plate 311 to squeeze against the bottom of the laying tunnel. At this time, the laying telescopic rod 310 is squeezed and contracted. This setting is beneficial to ensure that when the device is jolted, the locking pulley 313 and the laying pulley 314 are separated from the bottom of the laying tunnel. When the device vibrates up and down due to jolting, the laying electric rod 308 contracts and extends with the vibration amplitude, ensuring that the locking pulley 313 and the laying pulley 314 on the limiting plate 312 are always in contact with the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid line; Step 3: Adjust the tension of the power grid line. When the moving wheel 15 travels to a bumpy section, several sliding columns 12 at the bottom of the laying platform 1 slide up and down along the sliding plate 13. When the laying platform 1 moves downward, the laying electric rod 308 contracts. At this time, the travel of the power grid line is shortened, but the length of the power grid line remains unchanged, which will cause the tension of the power grid line to decrease; By setting the adjusting pulley 305, when the laying platform 1 moves downward at this time, the rotating shaft 304 on the adjusting pulley 305 slides upward along the chute on the fixed frame 301. At this time, the adjusting pulley 305 drives the power grid line to be stretched upward. This setting is beneficial to increase the tension of the power grid line, thereby preventing the power grid line from falling off the device; Step 4: Adjust the wire outlet speed of the power grid line according to the curve laying. The rack 501 on the steering tooth plate 402 drives the threaded rod 502 on the adjusting gear 503 to rotate. The rotation of the threaded rod 502 drives the limiting rod 506 at the top of the sliding block two 504 to move along the sliding rod two 505 away from the adjusting gear 503. The limiting rod 506 drives the bidirectional telescopic rod 510 on the driving column 508 at one end of the linkage rod two 507 to slide toward the inner side of the curve along the fixed disk 201. At this time, the extrusion force between the friction plate 512 of the bidirectional telescopic rod 510 close to the inner side of the curve and the control turntable 509 increases, and the extrusion force between the friction plate 512 of the bidirectional telescopic rod 510 close to the outer side of the curve and the control turntable 509 decreases. This setting is beneficial to increase the rotation resistance of the wire winding wheel 203 on the rotating column two 202 on the inner side of the curve, thereby slowing down the wire outlet speed of the wire winding wheel 203 on the inner side of the curve, so as to ensure that the power grid line can automatically adjust the wire outlet speed of different curve radii during curve laying and improve the quality of power grid line curve laying.

[0034] A specific application of this embodiment is: When using this power grid line laying construction device, first install the wire winding wheel 203 on the rotating column two 202. At this time, insert the wire winding wheel 203 with the power grid line along the rotating column two 202. At this time, the wire winding wheel 203 is squeezed by several fastening rods 207 on the rotating column two 202. The fastening rods 207 are squeezed to drive two sliding blocks one 204 inside the rotating column two 202 to move away from each other along the inner cavity of the rotating column two 202. At this time, the sliding block one 204 pulls the tension spring 205, and the tension of the tension spring 205 increases due to the tensile force. At this time, the pulling force of the tension spring 205 on the fastening rod 207 at one end of the sliding block one 204 increases. Such a setting is beneficial to increasing the clamping force of the fastening rod 207 on the wire winding wheel 203, so that the wire winding wheel 203 is fixed on the rotating column two 202, ensuring that the wire winding wheel 203 remains stable during rotation; by setting the laying mechanism 3, when the wire winding wheel 203 is installed on the rotating column two 202, one end of the power grid line on the wire winding wheel 203 is respectively passed through the adjusting pulley 305, the limiting pulley 302, the locking pulley 313, and the laying pulley 314, and then the tail of the power grid line is fixed at the bottom of the laying tunnel; at this time, several power grid lines are arranged on the laying mechanism 3. Such a setting is beneficial to separately arranging several power grid lines, thereby avoiding interference between the power grid lines and improving the laying quality of the power grid lines; when pushing the laying platform 1, the lower pressing plate 309 at the bottom is pushed down by the laying electric rod 308. The downward movement of the lower pressing plate 309 drives the locking pulley 313 and the laying pulley 314 on the limiting plate 312 at the bottom of the laying plate 311 to squeeze against the bottom of the laying tunnel. At this time, the laying telescopic rod 310 is squeezed and contracted. Such a setting is beneficial to ensuring that when the device is jolted, the locking pulley 313 and the laying pulley 314 are separated from the bottom of the laying tunnel. When the device vibrates up and down due to jolting, the laying electric rod 308 contracts and extends with the vibration amplitude, ensuring that the locking pulley 313 and the laying pulley 314 on the limiting plate 312 always contact the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid line; By setting up the laying mechanism 3, when the moving wheels 15 travel on a bumpy road section, several sliding columns 12 at the bottom of the laying platform 1 slide up and down along the sliding plate 13. When the laying platform 1 moves downward, the laying electric rod 308 contracts. At this time, the travel of the power grid wire is shortened, but the length of the power grid wire remains unchanged, which will cause the tension of the power grid wire to decrease. By setting up the adjusting pulley 305, when the laying platform 1 moves downward at this time, the rotating shaft 304 on the adjusting pulley 305 slides upward along the chute on the fixed frame 301. At this time, the adjusting pulley 305 drives the power grid wire to be stretched upward. This setting is beneficial to increasing the tension of the power grid wire, thereby preventing the power grid wire from falling off the device. By setting up the steering mechanism 4, when laying a curve, by adjusting the steering electric rod 401, the steering electric rod 401 drives the steering tooth plate 402 to move. The movement of the steering tooth plate 402 drives the steering gear 403 to rotate. The rotation of the steering gear 403 drives the moving wheels 15 at the bottom of the rotating column one 14 to rotate, thereby realizing the steering function of the device. In addition, when the device needs to turn, the steering electric rod 401 extends to drive the steering gear 403 at one end of the steering tooth plate 402 to rotate clockwise. At this time, the rack 501 on the steering tooth plate 402 drives the threaded rod 502 on the adjusting gear 503 to rotate. The rotation of the threaded rod 502 drives the limiting rod 506 at the top of the sliding block two 504 to move along the sliding rod two 505 away from the adjusting gear 503. The limiting rod 506 drives the bidirectional telescopic rod 510 on the driving column 508 at one end of the linkage rod two 507 to slide inward along the fixed disk 201 towards the curve. At this time, the extrusion force between the friction plate 512 of the bidirectional telescopic rod 510 close to the inner side of the curve and the control turntable 509 increases, and the extrusion force between the friction plate 512 of the bidirectional telescopic rod 510 close to the outer side of the curve and the control turntable 509 decreases. This setting is beneficial to increasing the rotation resistance of the wire winding wheel 203 on the rotating column two 202 on the inner side of the curve, thereby slowing down the wire outlet speed of the wire winding wheel 203 on the inner side of the curve, so as to ensure that the power grid wire can automatically adjust the wire outlet speed of different curve radii during curve laying and improve the quality of power grid wire curve laying.

10. The construction method of the power grid line laying construction device adopts the power grid line laying construction device as claimed in claim 9, characterized in that: It includes the following steps: Step 1: fix the electric grid line, and then insert the winding wheel (203) with the electric grid line onto the rotating column (202) along the rotating column (202). At this time, the winding wheel (203) and a plurality of fastening rods (207) on the rotating column (202) are squeezed, and the fastening rods (207) are squeezed to drive the two sliding blocks (204) inside the rotating column (202) to move away from each other along the inner cavity of the rotating column (202). At this time, the sliding block (204) pulls the tension spring (205), and the tension spring (205) is stretched and the elastic force increases. At this time, the tension of the tension spring (205) on the fastening rod (207) at one end of the sliding block (204) increases. This arrangement is conducive to increasing the clamping force of the fastening rod (207) on the winding wheel (203), so that the winding wheel (203) is fixed on the rotating column (202), ensuring that the winding wheel (203) remains stable during the rotation process; Step 2: laying the power grid line. When the laying platform (1) is pushed, the laying electric rod (308) pushes the lower pressure plate (309) at the bottom to move downward. The downward movement of the lower pressure plate (309) drives the locking pulley (313) and the laying pulley (314) on the limit plate (312) at the bottom of the laying plate (311) to be squeezed with the bottom of the laying tunnel. At this time, the laying telescopic rod (310) is squeezed and contracted. This arrangement is conducive to ensuring that when the device is bumped, the locking pulley (313) and the laying pulley (314) are out of contact with the bottom of the laying tunnel. When the device is bumped and vibrates up and down, the laying electric rod (308) contracts back and forth with the vibration amplitude, ensuring that the locking pulley (313) and the laying pulley (314) on the limit plate (312) are always in contact with the bottom of the laying tunnel, thereby reducing the influence of the up and down vibration of the device on the power grid line. Step 3: adjusting the tension of the power line. When the moving wheel (15) moves to a bumpy road section, a plurality of sliding columns (12) at the bottom of the laying platform (1) slide up and down along the sliding plate (13). When the laying platform (1) moves downward, the laying electric rod (308) contracts. At this time, the travel of the power line is shortened, but the length of the power line remains unchanged, which will cause the tension of the power line to decrease. By setting an adjusting pulley (305), when the laying platform (1) moves downward, the rotating shaft (304) on the adjusting pulley (305) slides upward along the sliding groove on the fixed frame (301). At this time, the adjusting pulley (305) drives the power line to stretch upward. This setting is conducive to increasing the tension of the power line, thereby preventing the power line from falling off the device. Step 4: The outlet speed of the power line is adjusted according to the laying of the curve. The rack (501) on the steering rack plate (402) drives the threaded rod (502) on the adjusting gear (503) to rotate. The rotation of the threaded rod (502) drives the limit rod (506) on the top of the sliding block (504) to move along the sliding rod (505) to the end away from the adjusting gear (503). The limit rod (506) drives the bidirectional telescopic rod (510) on the driving column (508) at one end of the linkage rod (507) to slide along the fixed plate (201) to the inner side of the curve. At this time, the bidirectional telescopic rod (510) on the driving column (508) at one end of the linkage rod (507) is moved to the inner side of the curve. The extrusion pressure between the friction plate (512) of the telescopic rod (510) and the control turntable (509) on the inner side of the curve is increased, while the extrusion pressure between the friction plate (512) of the bidirectional telescopic rod (510) and the control turntable (509) on the outer side of the curve is reduced. This arrangement is conducive to increasing the rotation resistance of the winding wheel (203) on the second rotating column (202) on the inner side of the curve, thereby slowing down the wire output speed of the winding wheel (203) on the inner side of the curve, thereby ensuring that the power grid line can automatically adjust the wire output speed of different curve radii when laying the curve, thereby improving the quality of the power grid line laying on the curve.
