Abstract
Description
Technical Field
[0001] This invention relates to the field of hoisting equipment technology, and in particular to a hoisting device for high-voltage transmission lines. Background Art
[0002] High-voltage transmission lines are supported by several power towers, with conductors laid on each tower to form a high-voltage power grid. The high-voltage lines have a significant height difference from the ground to ensure a safe distance between them. The high-voltage lines also require regular maintenance to remove foreign objects tangled in the transmission lines.
[0003] The common cleaning methods are: manual "flying vehicle" cleaning, where workers walk on the power lines to clean them from all angles. This method has several drawbacks: the power lines are dangerous, posing a safety hazard to workers; secondly, workers cannot clean precisely at specific points, resulting in indiscriminate cleaning and increasing their workload. Another method is drone cleaning, which offers the advantages of precision cleaning and mechanized operation compared to manual cleaning. However, due to the height of the power towers, it is impossible to fully observe the information on the power lines with the naked eye, so high-definition cameras are required for operation. In addition, the drone's battery does not have the capacity for prolonged operation, requiring frequent power supply replacements to maintain its working condition. Therefore, this method still has certain limitations. Summary of the Invention
[0004] The purpose of this invention is to address the above problems by providing a hoisting device for high-voltage transmission lines.
[0005] This invention includes a fixing plate, an adjusting mechanism, rollers, and a hoisting mechanism. The fixing plate is mirror-image arranged and connected to the adjusting mechanism. Rollers are provided on the inner side of the fixing plate for moving on the conductor. The hoisting mechanism is located at both ends of the fixing plate and includes a hoisting rope and a retracting assembly. The hoisting rope is used to lift the working equipment, and the retracting assembly can retract and extend the hoisting rope. This hoisting equipment for high-voltage transmission lines has a simple structure and is therefore lightweight, which helps to reduce the load on the conductor. Under the same conditions, it can lift heavier equipment. Therefore, hoisting can be easily achieved using a drone. Then, the hoisting assembly lowers the hoisting rope, and the object below is fixed by the hoisting rope, thereby easily lifting and hoisting the equipment. Continuous cyclical operation can be achieved to complete the hoisting work.
[0006] Specifically, the adjustment assembly includes a take-up / discharge motor and a take-up / discharge roller. The take-up / discharge motor is fixed inside the fixed plate, and the take-up / discharge roller is located outside the fixed plate. The output shaft of the take-up / discharge motor is connected to the input shaft of the take-up / discharge roller. Driving the take-up / discharge motor can drive the take-up / discharge roller to rotate, thereby taking up and releasing the suspension rope on the take-up / discharge roller. By driving the take-up / discharge roller to rotate through the set take-up / discharge motor, the suspension rope can be wound up or extended, thereby raising the equipment to the height of the conductor, thus facilitating equipment operation.
[0007] Specifically, it also includes a hoisting winch, which is fixed to the lifting equipment. By setting the hoisting winch on the lifting equipment, the overall mass of this design can be reduced in the non-lifting state, thereby reducing the load on the conductor and improving the overall safety.
[0008] Specifically, the adjustment mechanism includes a guide rod and an adjustment rod. One end of the guide rod and the adjustment rod are fixed to a fixed plate on one side, and the other end passes through the fixed plate on the other side. The guide rod and the fixed plate form a basic frame. It also includes an adjustment motor. The output shaft of the adjustment motor is connected to the input shaft of the adjustment rod. Driving the adjustment motor can drive the adjustment rod to move, which in turn drives the fixed plate on the other side to move axially along the guide rod, thereby adjusting the distance between the two fixed plates. By setting two parallel fixed plates on the guide rod, the two fixed plates can slide axially relative to the guide rod, thereby changing the distance between them. This makes the application range of this design wider. Furthermore, the distance between the two fixed plates is adjusted by the adjustment rod, thus eliminating the need for manual adjustment and improving the overall automation level and ease of operation.
[0009] Specifically, it also includes a fixing frame, which is disposed outside the roller and fixed to the fixing plate by fixing posts. The fixing frame can increase the reliability of the roller. The two ends of the roller are located on the fixing plate and the fixing frame respectively, so that the roller is more reliably fixed and can bear a greater weight.
[0010] Specifically, it also includes a guiding mechanism, with both ends of the guiding mechanism fixed to the bottom of the fixing plate at the same end. The middle part of the guiding mechanism is recessed downwards. With the guiding mechanism, when the wire is dropped, the guiding mechanism can guide the upper wire to both sides, thereby guiding the wire to the bottom of the roller, thus increasing the overall automation level and simplifying the overall structure.
[0011] Specifically, the guiding mechanism includes a guiding bracket, which includes two guiding plates. One end of each guiding plate is rotatably connected, and the other end is rotatably connected to the bottom of the corresponding fixed plates on both sides. The angle between the two guiding plates can also change with the change in the distance between the two fixed plates as the adjusting rod adjusts the distance between the two fixed plates. Therefore, the guiding plates are linearly changed when the whole is laid, which makes the whole more widely applicable.
[0012] Specifically, the bottom of the guide plate is not higher than the lower circumferential contour of the roller. Beneficial effects
[0013] The high-voltage transmission line hoisting equipment is lightweight and simple in structure, so it can be easily put into operation by drone. Then, the hoisting components lower the hoisting rope and fix the object below with the hoisting rope, so that the equipment to be hoisted can be easily lifted and hoisted to complete the online work. By setting the mounting plate into two pieces, the two mounting plates can be connected by only the adjustment mechanism, which simplifies the overall structure and reduces the overall weight. Secondly, the spacing between the two mounting plates can be adjusted by the adjustment rod, so that this hoisting equipment can adapt to wires of different widths, thereby improving the applicability of this equipment. By setting up a guiding mechanism, the gap between two wires with a very small gap can be widened, allowing them to slide down to the bottom of the roller, thus facilitating overall hoisting without the need for other precision components to align the wires and rollers.

Detailed Implementation
[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] In the description of this invention, it should be noted that the terms "middle," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] Example 1: The purpose of this invention is to provide a hoisting device for high-voltage transmission lines: Please combine Figure 1-10 Referring to the above, this device includes a fixed plate 10, an adjusting mechanism 20, a roller 30, and a hoisting mechanism 40. The adjusting mechanism 20 and the fixed plate 10 form a square whole. The roller 30 is located on the fixed plate 10, and the hoisting mechanism 40 is also set on the fixed plate 10. Therefore, when the roller 30 moves, it can drive the whole to move axially on the guide wire 70.
[0019] It is understood that the contact surface between the roller 30 and the guide wire 70 is a groove, which is U-shaped or V-shaped. Analyzing one side of the groove, it is formed by alternating inclined surfaces 302 and straight surfaces 303. During use, since the invention has a certain weight, after the roller 30 contacts the guide wire 70, the roller 30 is subjected to gravity, and the guide wire 70 is subjected to the squeezing force of the inclined surface 302 of the roller 30. This increases the normal pressure between the guide wire 70 and the roller 30, making the contact between the guide wire 70 and the roller 30 more stable. This makes the lifting robot more stable, preventing violent shaking and movement, and ensuring a smoother lifting process.
[0020] In practical use, the relationship between the roller 30 and the conductor 70 can be divided into two states. In the first state, the surface of the conductor 70 is subjected to the normal force of the inclined surface 302. At this time, the surface of the conductor 70 is in contact with the inclined surface 302 of the roller groove. As the hoisting equipment for high-voltage transmission lines descends onto the conductor 70, the conductor 70 is tightly clamped between the inclined surfaces 302 due to the relationship between them, thus ensuring the stability of the roller 30 on the conductor 70. In the second state, the conductor 70 is subjected to the lateral squeezing force. At this time, the inclined support force of the surface of the conductor 70 and the inclined surface 302 below, as well as the static friction force of the straight surface 303, act together between the conductor 70 and the roller 30, so that the hoisting equipment for high-voltage transmission lines can be stably clamped on the conductor 70, thereby ensuring the safety and stability of the construction.
[0021] The fixing plate 10 is sheet-shaped and consists of two pieces. The two fixing plates 10 are arranged in parallel and spaced apart, and are connected by the adjustment mechanism 20 to form a whole. In addition, the adjustment mechanism 20 can adjust the spacing between the two fixing plates 10. During use, the two fixing plates 10 with different spacings can adapt to different wire widths of the conductors 70, thereby improving the overall applicability. Furthermore, the fixing plate 10 is provided with multiple mounting positions for mounting various components, and the remaining parts are provided with weight-reducing holes to reduce the overall weight and thus reduce the load on the conductors 70.
[0022] It is understood that a roller 30 is provided on the inner side of the fixing plate 10, and a rolling motor 301 is provided on the outer side of the fixing plate 10. The position of the rolling motor 301 corresponds to the position of the roller 30. The rolling motor 301 can drive the roller 30 to rotate, thereby making axial movement on the wire 70 (the driving relationship between the rolling motor 301 and the roller 30 is the prior art, and the power supply 50 is also a well known method to those skilled in the art, and will not be described in detail here).
[0023] The adjustment mechanism 20 includes guide rods 201 and adjustment rods 202. Guide rods 201 are located on both sides of adjustment rods 202. The two guide rods 201 and two fixed plates 10 form a square frame structure. One end of the guide rod 201 is fixed to one of the fixed plates 10, and the other end passes through the other fixed plate 10. The other fixed plate 10 can move axially along the guide rods 201. The adjustment rod 202 is located between the two guide rods 201. One end of the adjustment rod 202 is rotatably connected to one of the fixed plates 10, and the other end is threaded and extends to the outside of the other fixed plate 10. The mechanism also includes an adjustment motor 203. The output shaft of the adjustment motor 203 is connected to the input shaft of the adjustment rod 202. When the adjustment motor 203 is started, the adjustment rod 202 can be rotated, thereby causing the fixed plate 10 threaded to the adjustment rod 202 to move axially along the guide rods 201, thereby adjusting the distance between the two fixed plates 10. This makes the design more widely applicable and reliable.
[0024] The hoisting mechanism 40 is respectively disposed at both ends of the fixed plate 10, and there are four sets in total. The hoisting mechanism 40 includes a take-up and release motor 402 and a take-up and release roller 401. The take-up and release motor 402 and the take-up and release roller 401 are respectively disposed on the inner and outer sides of the fixed plate 10 and are connected to each other.
[0025] It is understandable that an external winch 405 can also be used. By fixing the winch 405 to the equipment to be lifted, a wider range of options can be selected when choosing the hoist 402. In addition, setting the winch 405 on the equipment to be lifted makes the lifting process more stable. Furthermore, the position and number of the winches 405 correspond one-to-one with the position and number of the lifting ropes 403. The lower ends of the lifting ropes 403 are fixed to the corresponding winches 405. When the winch 405 is started, the lifting ropes 403 are pulled up and move upwards, driving the equipment to be lifted into the air, thus completing the lifting step. This setting not only reduces the load pressure of a single motor, but also allows the hoist 402 and the winch 405 to be started simultaneously as needed, thereby increasing the overall lifting or lowering speed and improving the efficiency of lifting or lowering.
[0026] In addition, a fixing frame 601 is included. The fixing frame 601 is located outside the roller 30 and is fixed to the fixing plate 10 by a fixing post 602. Therefore, a cavity for accommodating the roller 30 is formed between the fixing frame 601 and the fixing plate 10. This arrangement makes the roller 30 more reliable.
[0027] A guide bracket is provided at the bottom of the fixed frame 601. The guide bracket is formed by two guide plates 603 rotatably connected. The two ends of the guide bracket are respectively rotatably connected to the bottom of the two fixed frames 601 at the same end. It can be understood that the lowest point of the guide plate 603 is not higher than the lower circumferential contour of the roller 30. Therefore, when the entire equipment is not in operation, the guide bracket is the lowest point of the whole.
[0028] In practical use: Select a suitable line segment for drone takeoff. The drone's onboard camera performs initial focusing and measures the distance between the guide wire 70 and the drone in real time, feeding this data back to the handheld client. Based on this feedback, the operator adjusts the drone's status in real time and controls it to fly directly above the guide wire 70. Using the camera's feedback, the operator determines whether the lowest point of the guide plate 603, i.e., the lowest point of the guide bracket, is located between the guide wires 70. If so, the drone's altitude is immediately reduced. During descent, the lowest point of the guide bracket inserts between the two guide wires 70. As the drone descends, the guide bracket guides the guide wires 70 to both sides. As the drone descends, because the end of the guide bracket is connected to the bottom of the fixed frame 601, and there is a small gap between the fixed frame 601 and the end face of the roller 30, the wire 70 is guided to the end of the guide bracket during descent and slides into the lower part of the roller 30, where it is clamped. At this point, the descent stops, and then the adjustment motor 203 is started. The adjustment motor 203 drives the adjustment rod 202 to rotate. The adjustment rod 202 is threadedly connected to another fixed piece 10. Therefore, when the adjustment rod 202 rotates, it drives the two fixed pieces 10 to move closer to each other. When the width of the two fixed pieces 10 is the same as the distance between the wire 70, the adjustment motor 203 is stopped, and the drone is withdrawn.
[0029] By controlling the rolling motor 301 to drive the roller 30 to rotate, the whole unit moves along the guide. After the whole unit moves to the appropriate lifting position, the roller 30 stops moving. At this time, the take-up and release motor 402 is controlled to rotate, which drives the take-up and release roller 401 to rotate and begins to release the lifting rope 403 downward. Then, the end of the lifting rope 403 is fixed to the equipment to be lifted. The take-up and release motor 402 is controlled to drive the take-up and release roller 401 to rotate in the opposite direction, thereby winding the lifting rope 403 onto the take-up and release roller 401. As the take-up and release roller 401 rotates, the equipment to be lifted also slowly rises.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
