Description

Technical Field

[0001] This utility model relates to the technical field of power construction line-laying equipment, specifically a line-laying device for power construction. Background Technology

[0002] Power construction refers to various engineering operations related to the construction, installation, and maintenance of power systems. It encompasses the construction and modification of facilities in power generation, transmission, and distribution, such as erecting transmission lines, installing transformers, and laying cables. The goal is to ensure the safe and stable transmission of electricity to users. Cable laying machines are key tools used in power construction for laying cables. The main reasons for their use are as follows: First, they prevent cables from becoming tangled, knotted, or having their insulation damaged due to friction and pulling during manual laying, ensuring cable integrity. Second, they allow for uniform control of laying speed and tension through mechanical transmission, resulting in straighter cable laying that meets construction specifications for sag and spacing. Third, in long-distance transmission line construction, cable laying machines can significantly improve work efficiency and reduce manpower input.

[0003] The existing power construction cable laying device involves smoothly installing the cable reel on the main shaft of the cable laying device and fixing it with bolts or clamps. Then, the cable is pulled to lay the cable. When the laying speed is observed to be too fast, the worker presses down the lever to make the friction plate contact the main shaft of the cable laying device, increasing its friction and thus reducing the laying speed.

[0004] Existing power construction cable laying devices require operators to manually apply pressure and adjust the friction force using a lever handle. This results in a high degree of reliance on manual operation, insufficient dynamic adaptability, and lag in manual adjustment, making it impossible to respond promptly to sudden load changes. Therefore, we propose a new type of power construction cable laying device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cable laying device for power construction that can respond quickly and dynamically in real time, keep the laying speed always matching the construction requirements, ensure uniform cable tension, and eliminate the need for manual intervention. This effectively improves the quality and service life of cable laying and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power line laying device, including a support frame, with a rotating shaft rotatably connected to the opposite sides of the two support frames, and a mounting plate provided on the outside of each rotating shaft, and also including an adjustment mechanism;

[0007] Adjustment mechanism: It includes a groove, support blocks, guide rods, and arc plates. The left side of the support frame on the left side has a groove, and the right inner wall of the groove has evenly distributed support blocks. The inside of each support block is slidably connected to a guide rod. The end of the guide rod near the center of the rotating shaft is fixedly connected to an arc plate. The inner arc surface of the arc plate is provided with friction plates. The outer end of the left rotating shaft extending into the groove is installed in conjunction with the arc plate. It provides real-time and rapid dynamic response, keeps the cable laying speed always matching the construction requirements, ensures uniform cable tension, requires no manual intervention, and effectively improves the quality and service life of cable laying.

[0008] Furthermore, a microcontroller is installed on the outside of the support frame. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the adjustment mechanism also includes a rotating column, a turntable, an arc groove, and a sliding column. The rotating column is rotatably connected to the left inner wall of the groove, and the turntable is fixedly connected to the right end of the rotating column. The turntable has evenly distributed arc grooves in the middle. Sliding columns are provided on the left side of the guide rod. The outside of the sliding columns is slidably connected to the inside of the horizontally adjacent arc grooves to realize synchronous sliding of the guide rod.

[0010] Furthermore, the adjustment mechanism also includes a drive assembly, which includes a worm gear and a worm. The worm gear is fixedly sleeved on the outside of the turntable, and the worm is rotatably connected between the front and rear inner walls of the groove. The worm gear and the worm are meshed together to ensure stable adjustment.

[0011] Furthermore, the drive assembly also includes a motor, which is located on the front side of the support frame on the left. The rear end of the motor's output shaft is fixedly connected to the front end of the worm gear, and the input end of the motor is electrically connected to the output end of the microcontroller to provide adjustment drive.

[0012] Furthermore, it also includes a speed sensor, which is located on the right side of the support frame. The drive shaft of the speed sensor is in contact with the right end of the rotating shaft on the right side. The speed sensor is bidirectionally electrically connected to the microcontroller to monitor the wire feeding speed in real time.

[0013] Furthermore, it also includes rectangular tubes and rectangular columns. The rectangular tubes are respectively set at the bottom left side of the right support frame, and the rectangular columns are respectively set at the bottom right side of the left support frame. The rectangular columns are all slidably connected to the inside of the rectangular tubes on the same side. The upper surface of the rectangular columns is provided with evenly distributed fixing holes. The left end of the rectangular tubes is respectively threaded with fixing pins. The upper end of each fixing pin is fixedly connected with a knob. The fixing pins are installed in conjunction with the fixing holes to improve the applicability of the wire feeder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This power construction cable laying device has the following advantages:

[0015] The motor drives the worm gear to rotate, and the worm gear drives the turntable to rotate. The shape of the arc groove forces the sliding column to drive the guide rod to slide horizontally within the support block. The sliding of the guide rod causes the arc plate to move closer to or away from the rotating shaft. The friction plate on the inner side contacts the surface of the rotating shaft and generates friction, which hinders the rotation of the rotating shaft. This allows for speed adjustment during cable laying, resulting in a faster response speed, dynamic matching of laying speed, uniform cable tension, reduced insulation wear caused by sudden speed changes, and significantly improved construction efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a power line laying device for power construction, including a support frame 1, with rotating shafts 2 rotatably connected to opposite sides of the two support frames 1, and mounting plates provided on the outside of each rotating shaft 2. It also includes an adjustment mechanism 6, a microcontroller 5 on the outside of the support frame 1, the input end of the microcontroller 5 being electrically connected to an external power source, and a speed sensor 7. The speed sensor 7 is located on the right side of the right support frame 1, and its drive shaft contacts the right end of the right rotating shaft 2. The speed sensor 7 is bidirectionally electrically connected to the microcontroller 5. (The speed sensor 7 can be a commonly used contact speed sensor in the prior art. The sensing head of the contact speed sensor contacts the measured physical quantity through a certain mechanical structure (such as a friction wheel). When the measured object is moving, the surface of the measured object will generate mechanical vibration on the sensing head of the contact speed sensor. The vibration sensor inside the sensing head can convert the generated vibration signal into an electrical signal, which is then digitally converted by a signal processor to obtain the measured speed signal.) It also includes rectangular cylinders 3 and rectangular columns 4. The rectangular cylinders 3 are respectively located at the bottom of the left side of the right support frame 1, and the rectangular columns 4 are respectively provided with… On the bottom right side of the support frame 1 on the left, rectangular columns 4 are slidably connected to the interior of rectangular tubes 3 on the same side. Evenly distributed fixing holes 8 are provided on the upper surface of the rectangular columns 4. Fixing pins 9 are threaded onto the left end of each rectangular tube 3, and knobs are fixedly connected to the upper ends of the fixing pins 9. The fixing pins 9 are installed in conjunction with the fixing holes 8. When a cable reel is needed for power construction, first place the two support frames 1 in the designated positions, then slide the rectangular columns 4 inside the rectangular tubes 3 according to the length of the cable reel. When the distance between the two support frames 1 matches the length of the cable reel, tighten the knobs. Tighten the fixing pin 9 to insert it into the fixing hole 8, then wind the cable between the two rotating shafts 2 and fix it with the mounting plate on the outside of the rotating shaft 2. Pull one end of the cable to realize the cable feeding operation. During the cable feeding process, the microcontroller 5 controls the speed sensor 7 to start working. Its drive shaft is coaxially connected with the right rotating shaft 2. When the rotating shaft 2 rotates, the speed sensor 7 will detect the rotation speed of the rotating shaft 2 in real time and transmit its detection data to the microcontroller 5. The microcontroller 5 will integrate and analyze the received data, calculate the current cable feeding speed, and compare it with the preset standard speed.

[0023] Adjustment mechanism 6 includes a groove 61, support blocks 62, guide rods 63, and arc-shaped plates 64. The left side of the support frame 1 has a groove 61. The inner right wall of the groove 61 has evenly distributed support blocks 62. Guide rods 63 are slidably connected inside each support block 62. Arc-shaped plates 64 are fixedly connected to the ends of the guide rods 63 near the center of the rotating shaft 2. Friction plates (asbestos-free organic friction plates or semi-metallic friction plates can be used, ensuring stable friction performance while meeting construction efficiency and environmental standards) are provided on the inner arc surfaces of the arc-shaped plates 64. The outer end of the rotating shaft 2 extending into the groove 61 is fitted with the arc-shaped plates 64. The adjustment mechanism 6 also includes a rotating column 65, a turntable 66, an arc-shaped groove 67, and a sliding column 68. The rotating column 65 is rotatably connected to the left inner wall of the groove 61, and the turntable 66 is fixedly connected to the right end of the rotating column 65 (the central axes of the turntable 66, the rotating column 65, and the rotating shaft 2 coincide with each other). The turntable 66 has evenly distributed arc-shaped grooves 67 in the middle (the centers of the circles containing the four arc-shaped grooves 67 are not on the central axis of the turntable). The left side of the guide rod 63 is provided with sliding columns 68, and the outside of each sliding column 68 is slidably connected to the inside of the laterally adjacent arc-shaped groove 67. The adjustment mechanism 6 also includes a drive assembly 69, which includes a worm gear 691 and a worm 6. 92. A worm gear 691 is fixedly sleeved on the outside of the turntable 66. A worm 692 is rotatably connected between the front and rear inner walls of the groove 61. The worm gear 691 and the worm 692 are meshed together. The drive assembly 69 also includes a motor 693, which is located on the front side of the support frame 1 on the left. The rear end of the output shaft of the motor 693 is fixedly connected to the front end of the worm 692. The input end of the motor 693 is electrically connected to the output end of the microcontroller 5. When the microcontroller 5 determines that the wire feeding speed needs to be adjusted, it controls the motor 693 to start working. The operation of the motor 693 drives the worm 692 to rotate. Since the worm gear 691 and the worm 692 are meshed together, the worm gear 691 rotates accordingly. The turntable 66 is rotated, and an arc-shaped groove 67 is provided on the turntable 66. The sliding column 68 is embedded in the arc-shaped groove 67. When the turntable 66 rotates, the shape of the arc-shaped groove 67 forces the sliding column 68 to drive the guide rod 63 to slide horizontally within the support block 62. The end of the guide rod 63 near the rotating shaft 2 is fixedly connected to the arc-shaped plate 64. The sliding of the guide rod 63 causes the arc-shaped plate 64 to move closer to or away from the rotating shaft 2. When the arc-shaped plate 64 moves closer to the rotating shaft 2, the friction plate on its inner side contacts the surface of the rotating shaft 2 and generates friction, which hinders the rotation of the rotating shaft 2, thereby slowing down the wire feeding speed. Conversely, the friction decreases and the wire feeding speed increases, thus realizing the adjustment of the wire feeding speed by the wire feeder according to the material of the cable.

[0024] The working principle of the cable laying device for power construction provided by this utility model is as follows: When the cable laying device is needed for power construction, firstly, place two support frames 1 in the designated positions. Then, according to the length of the cable roll, slide the rectangular column 4 inside the rectangular tube 3. When the distance between the two support frames 1 matches the length of the cable roll, tighten the fixing pin 9 so that it is inserted into the fixing hole 8. Then, place the cable roll between the two rotating shafts 2 and fix it through the mounting plate on the outside of the rotating shaft 2. Pull one end of the cable to realize the cable laying operation. During the cable laying process, the microcontroller 5 controls the speed sensor 7 to start working. Its drive shaft is coaxially connected to the right rotating shaft 2. When the rotating shaft 2 rotates, the speed sensor 7 will detect the rotation speed of the rotating shaft 2 in real time and transmit the detection data to the microcontroller 5. The microcontroller 5 integrates and analyzes the received data, calculates the current cable laying speed, and compares it with the preset standard speed. When the microcontroller 5 determines that the wire feeding speed needs to be adjusted, the control motor 693 starts to work. The motor 693 drives the worm gear 692 to rotate. Since the worm wheel 691 is meshed with the worm gear 692, the worm wheel 691 rotates accordingly, thereby driving the turntable 66 to rotate. The turntable 66 has an arc-shaped groove 67, and the sliding column 68 is embedded in the arc-shaped groove 67. When the turntable 66 rotates, the shape of the arc-shaped groove 67 forces the sliding column 68 to drive the guide rod 63 to slide horizontally within the support block 62. The end of the guide rod 63 near the rotating shaft 2 is fixedly connected to the arc-shaped plate 64. The sliding of the guide rod 63 causes the arc-shaped plate 64 to move closer to or away from the rotating shaft 2. When the arc-shaped plate 64 moves closer to the rotating shaft 2, the friction plate on its inner side contacts the surface of the rotating shaft 2 and generates friction, which hinders the rotation of the rotating shaft 2, thereby slowing down the wire feeding speed. Conversely, the friction decreases and the wire feeding speed increases, thus realizing the adjustment of the wire feeding speed by the wire feeder according to the material of the cable.

[0025] It is worth noting that the microcontroller 5 disclosed in the above embodiments can be LPC1769, the motor 693 can be YS8024, and the speed sensor 7 can be E6B2-CWZ6C. The microcontroller 5 controls the operation of the motor 693 and the speed sensor 7 using methods commonly used in the prior art.
