Description

Technical Field

[0001] The invention belongs to the technical field of power grid construction, and in particular relates to an all-weather high-altitude cable laying method based on intelligent traction. Background Art

[0002] With the rapid development of modern power grid communication technology, cable laying operations have occupied a pivotal position in the construction of power infrastructure. However, in complex terrains such as mountains, canyons, and rivers, traditional cable laying methods have problems such as high risk factors, time-consuming and labor-intensive, and cumbersome procedures, which seriously restrict construction efficiency. At present, high-altitude cable laying uses improved traction equipment, a more advanced safety factor, and the use of drones for cable laying, which is particularly suitable for complex terrains such as mountainous areas and river areas, but drones are difficult to operate around the clock and are greatly affected by climatic conditions. There are also robot-assisted cable laying systems, but robots are mainly used for cable laying in urban underground pipelines. Summary of the invention

[0003] The purpose of the present invention is to provide an all-weather high-altitude cable laying method based on intelligent traction, which has high construction efficiency, is safe and reliable, is not affected by weather, and can operate uninterruptedly.

[0004] To achieve the above object, the present invention adopts the following technical solution: an all-weather high-altitude cable laying method based on intelligent traction, comprising the following steps: S1. Connect the traction rope to the unmanned tractor, and then place the unmanned tractor on the laid high-altitude cable; S2. Operate the unmanned tractor to compact the installed high-altitude cables; S3, the unmanned tractor pulls a traction rope from one power tower to the next power tower; S4. Tie the traction rope to the cable to be laid, and lay the cable to be laid between two adjacent power towers by controlling and pulling the traction rope.

[0005] The unmanned tractor comprises a mounting frame, on which a driving wheel, a lifting type wire pressing mechanism, a power device, an electrical control component and a rechargeable battery are arranged in sequence from top to bottom. The power device is connected to the driving wheel in a transmission manner. The upper end of the lifting type wire pressing mechanism cooperates with the driving wheel to press the laid cable. An anti-tilting device for the mounting frame rolling along the laid cable is respectively provided on the left and right sides of the upper part of the mounting frame; the electrical control component comprises a UBEC and a remote control receiver. The rechargeable battery is connected to the remote control receiver through the UBEC. The rechargeable battery supplies power to the lifting type wire pressing mechanism and the power device. The remote control receiver is respectively connected to the lifting type wire pressing mechanism and the power device for signal.

[0006] The mounting bracket includes a front guard plate and a rear mounting plate which are arranged at intervals before and after. The front guard plate and the rear mounting plate are connected by several bolts. There is an installation space between the front guard plate and the rear mounting plate. The upper side of the front guard plate is lower than the upper side of the rear mounting plate. A handle hole is provided at the upper end of the rear mounting plate, and a towing rope connection hole is provided at the lower part of the rear mounting plate.

[0007] The lifting wire pressing mechanism includes an electric push rod, a first DC motor forward and reverse driver, an upper sliding seat, a lower sliding seat, an L-shaped fixed seat, a first micro switch and two slide rails. The two slide rails are vertically fixed on the front side of the rear mounting plate. The upper sliding seat and the lower sliding seat are respectively slidably connected to the two slide rails. The first micro switch and the L-shaped fixed seat are fixed on the front side of the rear mounting plate. The first micro switch is located below the L-shaped fixed seat. The L-shaped fixed seat is located between the lower ends of the two slide rails. Two vertical rods are fixedly provided at the lower end of the lower sliding seat. A spring is sleeved on each vertical rod. The lower ends of the two vertical rods pass through the L-shaped fixed seat and are threadedly connected with adjusting nuts located directly above the first micro switch. The electric push rod is vertically arranged. The lower end and the upper end of the electric push rod are respectively connected to the lower sliding seat and the upper sliding seat by bolts. Two wire pressing wheels are rotatably provided on the upper sliding seat. The two wire pressing wheels are at the same height, arranged at intervals left and right and symmetrically arranged about the center line of the driving wheel. The signal output end of the first micro switch is connected to the signal input end of the first DC motor forward and reverse driver. The input end of the first DC motor forward and reverse driver is connected to the signal output end of the remote control receiver. The output end of the first DC motor forward and reverse driver is connected to the signal input end of the push rod motor of the electric push rod.

[0008] The power device includes a traveling motor and a second DC motor forward and reverse driver. The traveling motor is installed on the front side of the rear mounting plate. The main shaft of the traveling motor passes through the rear mounting plate and is coaxially connected with a driving pulley. The driving wheel is coaxially connected with a driven pulley located at the rear side of the rear mounting plate. The driving pulley and the driven pulley are connected by a synchronous belt. The signal input end of the traveling motor is connected to the signal output end of the second DC motor forward and reverse driver. The signal input end of the second DC motor forward and reverse driver is connected to the signal output end of the remote control receiver.

[0009] The two anti-tilting devices of the mounting bracket have the same structure and are symmetrically arranged left and right; the anti-tilting device on the right side of the mounting bracket includes a cross bar, an inclined strut, an auxiliary guide wheel and a second micro switch. The cross bar is arranged in the left-right direction. The left end of the cross bar is hinged to the rear mounting plate. The inclined strut is inclined with the left end lower and the right end higher. The left end of the inclined strut is hinged to the rear mounting plate. The right end of the inclined strut is hinged to the cross bar. The second micro switch is arranged at the right end of the second cross bar. The auxiliary guide wheel is rotatably arranged on the second cross bar and is located on the right side of the second micro switch. The auxiliary guide wheel is at the same height as the driving wheel and corresponds left and right. The output end of the second micro switch is connected to the signal input end of the second DC motor forward and reverse driver.

[0010] The specific process of step S1 is as follows: First, connect one end of the towing rope to the towing rope connection hole at the lower part of the rear mounting plate. Then, place the auxiliary guide wheels on both the left and right sides of the unmanned towing vehicle above the laid high-altitude cable, and place the driving wheels of the unmanned towing vehicle below the laid high-altitude cable. The entire unmanned towing vehicle is suspended on the laid high-altitude cable.

[0011] The specific process of step S2 is as follows: Operate the remote control to start the push rod motor. The remote control receiver receives the signal and transmits it to the first DC motor forward and reverse driver. The first DC motor forward and reverse driver starts the push rod motor to rotate forward, and the electric push rod extends, driving the upper sliding seat to move upward along the two guide rails. The two wire pressing wheels on the upper sliding seat also move upward accordingly, pressing the laid high-altitude cable upward. The electric push rod continues to extend. Blocked by the driving wheels, the upper sliding seat no longer moves upward. The lower sliding seat overcomes the elastic force of the two springs and moves downward along the two guide rails, and the two vertical rods also move downward until the adjusting nut at the lower end of the vertical rod touches the first micro switch. The first micro switch sends a signal that the wire pressing wheels are pressed in place to the first DC motor forward and reverse driver. The first DC motor forward and reverse driver controls the push rod motor to stop, and the length of the electric push rod is fixed. The pressure of the two wire pressing wheels on the laid high-altitude cable reaches the set value.

[0012] The specific process of step S3 is as follows: Operate the remote control to start the walking motor. After the receiver receives the signal, it sends an instruction to start the walking motor to the second DC motor forward and reverse driver. The walking motor starts and drives the driving wheels to rotate through the synchronous belt. The driving wheels travel on the laid high-altitude cable, and the two wire pressing wheels and the two auxiliary guide wheels also travel along the laid high-altitude cable. As the pulling length of the towing rope becomes longer and longer, the towing rope generates a certain pulling force on the mounting frame. Since the two auxiliary guide wheels are above the laid high-altitude cable, this can prevent the mounting frame from tilting in the left and right directions. When the unmanned towing vehicle approaches the power tower, the second micro switch first touches the insulating terminal on the power tower. The second micro switch sends a signal that the travel is in place to the second DC motor forward and reverse driver. The second DC motor forward and reverse driver controls the walking motor to stop, completing the transmission of the towing rope from one power tower to the next power tower.

[0013] Adopting the above technical solution, compared with the prior art, the present invention has the following innovations and beneficial effects: 1. The driving wheels are driven by the walking motor to drive the unmanned towing vehicle to move on the laid high-altitude cable. The two pressing wheels are made of polyurethane material, and the laid high-altitude cable is pressed by the electric push rod combined with the spring to increase the friction force. The pressing force can be adjusted by the adjusting nut, that is, by adjusting the position on the vertical rod. When the vertical rod moves downward, the touch of the adjusting nut and the first micro switch realizes the stop of the push rod motor, so that the spring has different elastic forces.

[0014] The traveling motor and rechargeable battery are arranged below the mounting frame, reducing the impact of the already laid high-altitude cables on them. The mounting frame is made of insulating material to ensure the safety of the equipment in a high-voltage environment. The synchronous belt, driving pulley, and driven pulley achieve synchronous movement between the driving wheel and the traveling motor. The setting of the second microswitch provides automatic stop protection, ensuring that the unmanned tractor travels more safely on the already laid high-altitude cables between two power transmission towers.

[0015] 2. The design of the auxiliary guide wheels ensures the stability of the unmanned tractor during operation, preventing the left-right skew of the mounting frame of the unmanned tractor caused by cable sway or complex terrain. The two cross bars of the anti-mounting frame tilting device can adjust the height of the auxiliary guide wheels by using diagonal braces of different lengths, thereby ensuring the friction between the auxiliary guide wheels and the already laid high-altitude cables to ensure stability. In addition, by disassembling the diagonal braces, the cross bars can be folded parallel to the rear mounting plate, facilitating transportation and storage.

[0016] In summary, the present invention solves the problem of cable laying in complex terrains, and has the characteristics of efficient traction, safety and reliability, strong adaptability, convenient operation, easy carrying, and can be dropped by a drone. The working principle of the present invention is scientific and reasonable, and can be widely applied to cable laying projects in the fields of electric power, communication, transportation, etc., especially having significant advantages in remote areas and complex terrains.
