Description

Technical Field

[0001] This application relates to the field of overhead line de-icing technology, and in particular to a mounting bracket for a de-icing device and a de-icing system. Background Technology

[0002] When overhead transmission lines operate in areas with heavy icing, severe icing can threaten the safety of the power grid. In existing technologies, mechanical vibration de-icing devices are usually installed on overhead lines. These devices have impact components that can impact the overhead lines, causing the ice on the overhead lines to break and fall off.

[0003] However, installing de-icing devices involves high-altitude operations such as manually climbing power transmission towers, which are dangerous and inefficient. While using drones to carry the devices to the cables for installation is feasible, drones have limited payload capacity and are difficult to take off in harsh environments. Therefore, existing methods for installing de-icing devices are difficult to operate, resulting in low installation efficiency. Utility Model Content

[0014] Optionally, the middle part of the support frame is bent to form a hook structure with an arc shape, and the connecting part is provided at one end of the support frame.

[0015] Optionally, the two ends of the support frame are bent toward the direction away from the opening of the hook structure, so that the two ends of the support frame respectively form a first bent section and a second bent section;

[0016] The connecting part is disposed on the first curved section, and the traction part is installed on the second curved section.

[0017] Optionally, a rib is provided in the opening of the first curved section, and the edge of the rib is attached to the inner wall of the first curved section so that the rib supports the first curved section.

[0018] Optionally, the end of the guide rope away from the launching end is a detachable end, and the connection point between the guide rope and the connecting part is between the detachable end and the launching end;

[0019] When the support frame is hooked to the overhead line, the disassembly end and the launching end are respectively on both sides of the overhead line, and the disassembly end receives traction force to drive the support frame to move away from the overhead line, so that the overhead line is disengaged from the hook structure.

[0020] Optionally, the connecting part includes a plurality of connecting holes penetrating the support frame, and the plurality of connecting holes are spaced apart along the length direction of the support frame;

[0021] The guide rope is provided with a limiting knot between the disassembly end and the launching end. The guide rope passes through a plurality of the connecting holes, and the limiting knot is limited between at least two of the connecting holes, so that the launching end and the disassembly end are on both sides of the plurality of connecting holes.

[0022] Optionally, the traction unit includes a pulley block and a traction rope, wherein the pulley block is fixedly connected to the support frame;

[0023] The traction rope is wound around the pulley block and is used to connect to the de-icing device.

[0025] Optionally, the pulley block includes a connecting frame and a fixed pulley. The connecting frame is fixedly connected to the support frame, the fixed pulley is rotatably connected to the connecting frame, and the traction rope is wound around the fixed pulley.

[0029] The technical solution provided in this application has the following advantages compared with the prior art:

[0030] The de-icing device mounting frame provided in this application has a connecting part and a traction part on the support frame. The support frame is bent to form a hook structure. The connecting part and the traction part are located on both sides of the opening of the hook structure. The connecting part is located near the edge of the opening of the hook structure and is connected to a guide rope. One end of the guide rope is a launching end, which can be launched by a launching device or manually across the overhead line so that the guide rope is laid on the overhead line. When the guide rope is laid on the overhead line, the launching end receives traction force and can drive the support frame towards the overhead line so that the opening of the hook structure can accommodate the overhead line, so that the support frame hooks with the overhead line. The traction part is connected to the de-icing device and can pull the de-icing device towards the support frame so that the de-icing device can be moved to the overhead line for de-icing. The operator only needs to perform operations such as launching the guide rope and applying tension from the ground or a low-risk location to hook the support frame onto the overhead line and pull the de-icing device to the de-icing location through the traction part, avoiding safety risks such as falling from height and electric shock. After the guide rope is launched over the overhead line, pulling the guide rope hooks the support frame onto the overhead line. The de-icing device is then pulled to the overhead line by the traction unit on the support frame, eliminating the need for drones to install the de-icing device. This avoids the difficulty of installing the de-icing device due to the limited payload and the inability of drones to take off in harsh environments. Through the cooperation of the support frame, guide rope, and traction unit, the installation operation of the de-icing device is simplified, the installation efficiency of the de-icing device is improved, and key support is provided for rapid de-icing operations of the power grid in areas with heavy icing.

Detailed Implementation

[0036] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0038] Reference Figure 1 and Figure 2 As shown, the first aspect of this application provides a mounting frame for a de-icing device, comprising: a support frame 1 having a hook structure formed by bending, the support frame 1 having a connecting portion 2 formed at the edge of the opening of the hook structure; a guide rope connected to the connecting portion 2, one end of which is a launching end for passing over an overhead line 4 so that the guide rope is laid on the overhead line 4; and a traction portion 3 disposed on the support frame 1 and located on the side of the opening of the hook structure away from the connecting portion 2, the traction portion 3 being connected to a de-icing device 5 to traction the de-icing device 5 toward the support frame 1; when the guide rope is laid on the overhead line 4, the launching end receives traction force and can drive the support frame 1 toward the overhead line 4 so that the opening of the hook structure accommodates the overhead line 4 so that the support frame 1 is hooked with the overhead line 4.

[0039] Specifically, the support frame 1 is made of high-strength alloy material or metal, and has a rigid structure. The middle part of the support frame 1 is bent to form a hook structure. The shape of the hook structure is adapted to the outer diameter of the overhead line 4. The hook structure can be U-shaped or arc-shaped. The overhead line 4 can enter the interior of the hook structure through the opening of the hook structure so that the support frame 1 can be hooked onto the overhead line 4.

[0040] The support frame 1 has a connecting part 2 at the edge near the opening of the hook structure. The connecting part 2 can be a through hole on the support frame 1, so that the guide rope can be tied to the support frame 1 through the through hole; or the connecting part 2 can be a plate structure, which is welded to the support frame 1. The plate structure has a through hole, and the guide rope passes through the through hole of the plate structure and is tied to the plate structure.

[0041] The guide rope is made of high-strength, wear-resistant nylon rope or steel wire rope, and its diameter is determined according to the weight of the support frame 1 and the traction requirements. One end of the guide rope is the launching end, and a counterweight can be tied to the launching end for easy launching. The counterweight is launched over the overhead line 4 by the launching device, so that the guide rope moves over the overhead line 4 with the counterweight.

[0042] One end of the guide rope away from the launching end can be connected to the connecting part 2. After the guide rope passes over the overhead line 4, pulling the launching end will cause the guide rope to pull the support frame 1 toward the overhead line 4. Since the traction point of the guide rope on the support frame 1 is at the edge of the opening of the hook structure, when the support frame 1 moves to the overhead line 4, the overhead line 4 will be able to enter the opening of the hook structure so that the hook structure can be hooked onto the overhead line 4.

[0043] When the support frame 1 is attached to the overhead line 4, the guide rope is on one side of the overhead line 4 and the launching end is on the ground. When disassembling the support frame 1, the worker throws the launching end in the opposite direction to pass over the overhead line 4, which is to perform the reverse throwing operation of the guide rope, so that the guide rope is on the other side of the overhead line 4. At this time, pulling the launching end applies a reverse traction force to the connecting part 2, which can make the hook structure move away from the overhead line 4, so that the overhead line 4 is disengaged from the hook structure.

[0044] The traction part 3 can be a fixed pulley, which is installed on the support frame 1 by welding or bolting, and is strictly located on the side of the hook structure opening away from the connecting part 2, that is, the traction part 3 and the connecting part 2 are on both sides of the opening of the hook structure. After the hook structure is attached to the overhead line 4, the traction part 3 and the connecting part 2 are on both sides of the overhead line 4 without interfering with each other. The guide rope and the traction part 3 are on both sides of the overhead line 4. When the traction part 3 pulls the de-icing device, one end of the support frame 1 is subjected to a downward pull. At this time, pulling the guide rope can make the other end of the support frame 1 subjected to a downward pull, ensuring that the support frame 1 remains balanced.

[0045] Alternatively, the traction unit 3 can be equipped with a winch, which has a traction rope. The free end of the traction rope is connected to the de-icing device. Once the winch is started, it can pull the de-icing device toward the support frame 1.

[0046] When the mounting frame of the de-icing device provided in this application embodiment is used, the first step is to launch the guide rope: the operator, at a safe position on the ground or at the bottom of the tower, launches the launch end of the guide rope toward the overhead line 4, so that the launch end passes over the overhead line 4 and falls to the ground or operating platform on the other side of the overhead line 4. At this time, the guide rope is laid on the overhead line 4.

[0047] Next, the support frame 1 is hooked to the overhead line 4: the operator pulls the launching end of the guide rope. Since the guide rope is fixed to the connection part 2 of the support frame 1, the pulling force is transmitted to the connection part 2 through the guide rope, thereby driving the support frame 1 to move towards the overhead line 4 along the extension direction of the guide rope. During the movement, the opening of the hook structure of the support frame 1 always faces the overhead line 4. As the pulling force is continuously applied, the opening of the hook structure gradually accommodates the overhead line 4 until the overhead line 4 is completely inside the hook structure. At this time, the support frame 1 is stably hooked to the overhead line 4 through the hook structure; the support frame 1 maintains the connection with the overhead line 4 by relying on the shape limitation of the hook structure and its own weight.

[0048] Finally, the installation of the de-icing device 5 is completed: the de-icing device 5 is connected and fixed to the traction part 3 on the support frame 1 through its own connecting structure. After ensuring a reliable connection, the traction part 3 moves the de-icing device 5 toward the support frame 1. During the movement, since the support frame 1 is fixed on the overhead line 4, the de-icing device 5 will not shift until it moves to the position where it abuts the overhead line 4, completing the entire installation process.

[0049] The mounting frame for the de-icing device provided in this embodiment has a connecting part 2 and a traction part 3 on a support frame 1. The support frame 1 is bent to form a hook structure. The connecting part 2 and the traction part 3 are located on both sides of the opening of the hook structure. The connecting part 2 is located near the edge of the opening of the hook structure and is connected to a guide rope. One end of the guide rope is a launching end, which can cross the overhead line 4 by a launching device or by human force, so that the guide rope is laid on the overhead line 4. When the guide rope is laid on the overhead line 4, the launching end receives traction force and can drive the support frame 1 to move towards the overhead line 4, so that the opening of the hook structure can accommodate the overhead line 4, so that the support frame 1 is hooked with the overhead line 4. The traction part 3 is connected to the de-icing device and can pull the de-icing device towards the support frame 1, so that the de-icing device can be moved to the overhead line 4 for de-icing. Operators only need to perform operations such as launching the guide rope and applying tension from the ground or a low-risk location to hook the support frame 1 onto the overhead line 4. The de-icing device is then pulled to the de-icing location via the traction unit 3, avoiding safety risks such as falls from heights and electric shocks. After the guide rope is launched over the overhead line 4, pulling the guide rope hooks the support frame 1 onto the overhead line 4. The de-icing device is then pulled to the overhead line 4 by the traction unit 3 on the support frame 1. The installation of the de-icing device can be completed without relying on a drone, avoiding the difficulty of installing the de-icing device due to the drone's limited payload and inability to take off in harsh environments. The cooperation of the support frame 1, guide rope, and traction unit 3 simplifies the installation operation of the de-icing device, improves its installation efficiency, and provides crucial support for rapid de-icing operations of the power grid in heavily iced areas.

[0050] Reference Figure 1 and Figure 2 As shown, in some embodiments, the support frame 1 includes a connecting rod 12 and a plurality of sub-supports 11 fixed on the connecting rod 12, the plurality of sub-supports 11 being spaced apart along the length direction of the connecting rod 12;

[0051] Each sub-bracket 11 is bent to form a hook structure, and the openings of the hook structures of multiple sub-brackets 11 face the same direction;

[0052] Each sub-support 11 is provided with a connecting part 2. The guide rope is connected to the connecting parts 2 of multiple sub-supports 11 so that the guide rope can drive multiple sub-supports 11 to move simultaneously.

[0053] There are multiple traction units 3, and multiple traction units 3 are fixed on multiple sub-supports 11.

[0054] With this configuration, multiple sub-supports 11 are spaced apart along the connecting rod 12, forming multiple hooks with the overhead line 4. This allows multiple connection points between the support frame 1 and the overhead line 4 to be spaced apart along the extension direction of the overhead line 4, improving the stability of the support frame 1 hooked onto the overhead line 4 and avoiding the risk of the support frame 1 tilting or falling off due to excessive force at a single point during the traction of the de-icing device 5.

[0055] Specifically, the main load-bearing structure of the support frame 1 is made of high-strength aluminum alloy or carbon fiber composite material, and is a straight strip in shape. Its length is determined according to the length of the de-icing device 5 and the installation requirements of the overhead line 4, and is usually 1-3m, with a diameter of 20-50mm, ensuring sufficient rigidity and bending resistance to bear the weight of multiple sub-supports 11 and the de-icing device 5. The surface of the connecting rod 12 is treated with anti-corrosion measures such as galvanizing or coating with anti-corrosion paint to adapt to the humid and low-temperature environment of areas with heavy icing and extend its service life.

[0056] The number of sub-supports 11 can be two or four. The specific number is determined according to the length of the connecting rod 12 and the support requirements of the de-icing device 5. The sub-supports 11 are fixed to the connecting rod 12 by welding, bolting or integral molding.

[0057] Multiple sub-supports 11 are evenly spaced along the length of the connecting rod 12. Each sub-support 11 is bent to form a hook structure, and the shape of the hook structure of each sub-support 11 is the same. The opening of the hook structure of all sub-supports 11 is in the same direction, so that the overhead line 4 can enter the multiple hook structures simultaneously.

[0058] Each sub-support 11 is provided with an independent connecting part 2, and each connecting part 2 is located in the same position on the sub-support 11, close to the opening edge of the hook structure, to ensure that the guide rope can apply a uniform tension to each sub-support 11 after connection.

[0059] The guide rope can be selected to include a main rope and multiple branch ropes. The branch ropes are connected to one end of the main rope, and the branch ropes are connected to the connecting parts 2 on multiple sub-supports 11. The end of the main rope away from the branch ropes is the launching end. When the worker pulls the main rope, the multiple sub-supports 11 will be pulled simultaneously. Alternatively, the guide rope can include multiple branch ropes, with one branch rope connected to each connecting part 2, and each branch rope has a launching end.

[0060] The number of traction units 3 corresponds one-to-one with the number of sub-supports 11. Each traction unit 3 is installed on a sub-support 11 by welding or bolting, and the position is located on the side of the hook structure opening of the sub-support 11 away from the connecting part 2. The de-icing device is connected to multiple traction units 3 so that the synchronous traction unit 3 can synchronously traction the de-icing device.

[0061] Multiple sub-supports 11 are connected as one unit by connecting rods 12. After the guide rope is launched, when the operator pulls the launching end, the pulling force is evenly transmitted to the connecting part 2 of each sub-support 11 through the guide rope, causing the entire support frame 1 to move towards the overhead line 4. During the movement, since the hook structure openings of the multiple sub-supports 11 face the same direction and are evenly spaced, they can be aligned with the overhead line 4 at the same time. When the support frame 1 moves to the preset position, the hook structure openings of all sub-supports 11 simultaneously accommodate the overhead line 4, so that the entire support frame 1 is stably hooked to the overhead line 4 through multiple sub-supports 11. Compared with the structure of a single sub-support, the hooking method of multiple sub-supports can greatly improve the connection stability between the support frame 1 and the overhead line 4, and prevent the support frame 1 from tilting or shaking when the de-icing device 5 is pulled later.

[0062] The de-icing device is located between multiple traction units 3. The multiple traction units 3 simultaneously apply traction force to the de-icing device, so that the de-icing device is subjected to uniform force. The multiple traction units 3 synchronously drive the de-icing device 5 to move smoothly along the overhead line 4 toward the support frame 1.

[0063] Reference Figure 1 and Figure 2 As shown, in some embodiments, the middle part of the support frame 1 is bent so that the support frame 1 forms a hook structure with an arc shape, and the connecting part 2 is provided at one end of the support frame 1.

[0064] This design ensures a high degree of fit between the curved structure and the overhead line 4, improving the stability of the connection between the support frame 1 and the overhead line 4. The connecting part 2 is located at the end of the support frame 1, which facilitates the machining of the connecting part 2 on the support frame 1 and ensures that the connecting part 2 does not affect the structural strength of the part of the support frame 1 used for connecting with the overhead line 4.

[0065] Specifically, the middle of the support frame 1 is bent to form a hook structure with a superior arc shape. The side projection of the hook structure is an arc, and the central angle of the arc is greater than 180°, ensuring the stability of the hook structure's connection with the overhead line 4. The arc length can be selected to be 1 / 2 to 2 / 3 of the circumference of the overhead line 4. This ensures sufficient coverage area for stable hooking while avoiding an excessively long arc that would result in a small opening in the hook structure, hindering the entry of the overhead line 4.

[0066] The two ends of the support frame 1 are at the edge of the opening of the hook structure. The connecting part 2 is at the end of the support frame 1, which is close to the edge of the opening of the hook structure. When the guide rope is pulled, the connecting part 2 drives the support frame 1 to move. The end of the support frame 1 with the connecting part 2 first passes the overhead line 4, and then the support frame 1 falls naturally, so that the overhead line 4 enters the opening of the hook structure, and the hook structure hooks with the overhead line 4.

[0067] Reference Figure 1 and Figure 2As shown, in some embodiments, the two ends of the support frame 1 are bent toward the direction away from the opening of the hook structure, so that the two ends of the support frame 1 form a first bent section 111 and a second bent section 112, respectively.

[0068] The connecting part 2 is disposed on the first curved section 111, and the traction part 3 is installed on the second curved section 112.

[0069] This design, with its curved sections at both ends, enhances the overall structural strength of the support frame 1. The first curved section 111 provides a more suitable installation position for the connecting part 2, and it also forms an arc-shaped surface at the edge of the opening of the hook structure, allowing the first curved section 111 to guide the overhead line 4 into the opening of the hook structure. The second curved section 112 provides ample operating space for the traction part 3 and the de-icing device 5, avoiding interference and collision between components during traction.

[0070] Specifically, the first curved section 111 is located at the end of the support frame 1 where the connecting part 2 is provided. It extends from one end of the arc-shaped hook structure and bends away from the opening of the hook structure. The end of the first curved section 111 has a smooth transition to avoid sharp edges, so as to form an arc-shaped surface at the edge of the opening of the hook structure. When the worker pulls the guide rope to move the support frame 1 toward the overhead line 4, the arc-shaped surface first contacts the overhead line 4, and the arc-shaped surface slides relative to the overhead line 4 so that the arc-shaped surface can guide the overhead line 4 into the opening of the hook structure.

[0071] The second curved section 112 is located at one end of the support frame 1 where the traction part 3 is provided. After extending from the other end of the arc-shaped hook structure, it also bends away from the opening of the hook structure. The second curved section 112 can form a platform structure for installing the traction part 3 at the end of the support frame 1, and make the orientation of the traction part 3 away from the opening of the hook structure, so as to avoid the traction part 3 blocking the opening of the hook structure.

[0072] Alternatively, a through hole can be drilled in the first curved section 111 as the connecting part 2, or a metal ring or an ear plate with an opening can be welded onto the first curved section 111 as the connecting part 2.

[0073] Reference Figure 1 and Figure 2 As shown, in some embodiments, a rib 113 is provided in the opening of the first curved section 111, and the edge of the rib 113 is attached to the inner wall of the first curved section 111 so that the rib 113 supports the first curved section 111.

[0074] With this configuration, the supporting effect of the rib plate 113 enhances the local structural strength of the first bending section 111 and improves the overall stability of the support frame 1.

[0075] Specifically, the side of the first curved segment 111 furthest from the opening of the hook structure is the inner wall of the first curved segment 111; the rib plate 113 is generally in the shape of an arc-shaped thin plate, and its shape is completely fitted with the shape of the inner wall of the first curved segment 111, that is, the radius of curvature of the rib plate 113 is consistent with the radius of curvature of the inner wall of the first curved segment 111, ensuring that the rib plate 113 can fit tightly against the inner wall of the first curved segment 111. The rib plate 113 can be connected to the inner wall of the first curved segment 111 by welding.

[0076] The design of rib 113 does not affect the normal operation and workflow of other components, and does not require adjustments to existing installation steps. Operators can adapt quickly, ensuring that installation efficiency is not affected.

[0077] In some embodiments, the end of the guide rope away from the launching end is the disassembly end, and the connection point between the guide rope and the connecting part 2 is between the disassembly end and the launching end.

[0078] When the support frame 1 is hooked to the overhead line 4, the disassembly end and the launching end are on both sides of the overhead line 4, and the disassembly end receives traction force that can drive the support frame 1 to move away from the overhead line 4 so that the overhead line 4 can be disengaged from the hook structure.

[0079] With this setup, the dismantling process does not require operators to work at height or use special dismantling tools. The dismantling of the support frame 1 can be completed simply by pulling the dismantling end of the guide rope on the ground. Furthermore, there is no need to throw the throwing end of the guide rope in the opposite direction, which simplifies the operation of dismantling the support frame 1 hooked to the overhead line 4.

[0080] Specifically, the guide rope is clearly divided into two functional ends: one end is the launching end and the other end is the disassembly end, and the connection point between the guide rope and the connecting part 2 is located between the disassembly end and the launching end; the disassembly end can be equipped with a handle or ring buckle for easy gripping or connection of traction tools, so that the operator can hold it stably in cold or humid environments such as rain and snow in areas with heavy ice.

[0081] The connection point between the guide rope and the connecting part 2 can be located in the middle of the guide rope. The specific location is determined according to the weight of the support frame 1 and the traction requirements, so as to ensure that when the support frame 1 is hooked to the overhead line 4, the disassembly end and the launching end can be located on both sides of the overhead line 4 respectively, and the operator can reach both ends on the ground at the same time.

[0082] When hooking the support frame 1 onto the overhead line 4, first fix the connection point of the guide rope to the through hole of the connecting part 2 through a knot or buckle to ensure a firm connection. At this time, the launching end of the guide rope faces the overhead line 4, and the disassembly end faces the direction of the operator. The operator holds the launching end and launches the end with the counterweight over the overhead line 4. After the launching end falls to the ground on the other side of the line, the guide rope is laid on the overhead line 4. At this time, the connection point is located directly below the overhead line 4, and the support frame 1 is suspended from the guide rope through the connection point. The disassembly end and the launching end are located on the ground on both sides of the overhead line 4. The operator can easily hold the disassembly end, and the launching end can be held by another operator or fixed to the ground anchor point.

[0083] The operator pulls the launching end, and the pulling force is transmitted to the connection point through the guide rope, causing the support frame 1 to move towards the overhead line 4 until the hook structure is hooked and fixed to the overhead line 4. After the hooking is completed, the disassembly end and the launching end are still located on both sides of the line and are in a slack state, which does not affect the traction and installation of the de-icing device 5.

[0084] When it is necessary to disassemble the support frame 1, such as after replacing the de-icing device 5 or completing the de-icing operation, first separate the de-icing device 5 from the traction unit 3. Then, the operator pulls the disassembly end of the guide rope. Since the connection point is located between the disassembly end and the launching end, and the disassembly end is relatively long, the pulling force is transmitted to the connection point through the guide rope, causing the support frame 1 to rotate around the contact point between the hook structure and the line, and move away from the overhead line 4. As the disassembly end is continuously pulled, the opening of the hook structure gradually moves away from the line until the overhead line 4 comes out of the opening of the hook structure. At this time, the support frame 1 separates from the line and falls to the ground under its own weight through the guide rope, completing the disassembly. If resistance is encountered during the disassembly process, such as slight jamming between the hook structure and the line, the operator on the other side can slightly pull the launching end to assist in adjusting the posture of the support frame 1, ensuring that the overhead line 4 is smoothly released from the hook structure of the support frame 1.

[0085] Reference Figure 1 and Figure 2 As shown, in some embodiments, the connecting part 2 includes a plurality of connecting holes 21 penetrating the support frame 1, and the plurality of connecting holes 21 are spaced apart along the length direction of the support frame 1.

[0086] A limiting knot is provided between the disassembly end and the launching end of the guide rope. The guide rope is passed through multiple connecting holes 21, and the limiting knot is limited between at least two connecting holes 21 so that the launching end and the disassembly end are on both sides of the multiple connecting holes 21.

[0087] This design, with multiple connection holes 21, provides multiple contact points between the guide rope and the support frame 1, reducing wear between them. The limiting knot enables automatic positioning of the guide rope and the connecting part 2, eliminating the need for manual adjustment of the connection point position by the operator.

[0088] Specifically, the number of connecting holes 21 is usually two to four, and multiple connecting holes 21 are evenly spaced along the length of the support frame 1; a limiting knot is set between the disassembly end and the launching end of the guide rope by wrapping and knotting. The size of the limiting knot is larger than the connecting hole 21, so that the limiting knot cannot pass through the connecting hole 21; the guide rope passes through multiple connecting holes 21 in sequence, and a limiting knot is set between multiple connecting holes 21. Since the diameter of the limiting knot is larger than the diameter of the connecting hole, the limiting knot will be blocked by the connecting hole 21 on the side closer to the launching end, and will also be blocked by the connecting hole 21 on the side closer to the disassembly end, thereby fixing the relative position of the guide rope and the connecting part 2, ensuring that the launching end and the disassembly end are located on both sides of multiple connecting holes 21 respectively.

[0089] Reference Figure 1 and Figure 2 As shown, in some embodiments, the traction unit 3 includes a pulley block and a traction rope. The pulley block is fixedly connected to the support frame 1. The traction rope is wound around the pulley block and is used to connect with the de-icing device 5. When the support frame 1 is hooked onto the overhead line 4, the traction rope moves relative to the pulley block to pull the de-icing device 5 toward the support frame 1.

[0090] This configuration, with the pulley system employing rolling friction, reduces traction resistance. The cooperation between the traction rope and the pulley system makes the traction process of the de-icing device 5 smoother, and the movement speed uniform and controllable. At the same time, the traction rope is highly replaceable; if the traction rope is worn or broken, only the traction rope needs to be replaced, without replacing the entire traction unit, thus reducing the maintenance cost of the equipment.

[0091] Specifically, the pulley block can use a single fixed pulley or a combination of multiple pulleys, such as a force-saving pulley block of fixed pulleys and movable pulleys; the pulley block also includes a fixed bracket, which is connected to the support frame 1 by welding or bolting. The fixed pulley is installed on the fixed bracket and will not interfere with other parts of the support frame 1.

[0092] The traction rope is wound around a pulley block. One end of the traction rope is used to connect to the de-icing device, and the other end is used for workers to grip or to connect to traction equipment such as winches. First, the de-icing device 5 is connected and fixed to one end of the traction rope through its own connecting structure. Then, the operator holds the other end of the traction rope on the ground and pulls the traction rope away from the overhead line 4. Since the traction rope is wound around the fixed pulley of the pulley block, the tension is transmitted to the de-icing device 5 through the traction rope, causing the de-icing device 5 to move towards the support frame 1 along the extension direction of the overhead line 4.

[0093] Reference Figure 1 and Figure 2 As shown, in some embodiments, the pulley block includes a connecting frame 31 and a fixed pulley 32. The connecting frame 31 is fixedly connected to the support frame 1, and the fixed pulley 32 is rotatably connected to the connecting frame 31. The traction rope is wound around the fixed pulley 32.

[0094] With this configuration, the connecting frame 31 provides the mounting base for the fixed pulley 32, which has a simple structure and low cost.

[0095] Specifically, the connecting frame 31 has an overall U-shaped frame structure, including two parallel side arms and a crossbeam connecting the two side arms. Each side arm has a coaxial circular mounting hole in the middle for mounting the central shaft of the fixed pulley 32; the U-shaped opening of the connecting frame 31 faces away from the hook structure of the support frame 1, ensuring that there is enough space for the traction rope to be wound after the fixed pulley 32 is installed, and that it will not interfere with the support frame 1.

[0096] The fixed pulley 32 includes a wheel body and a central shaft. The central shaft is rotatably connected to the center of the wheel body. The central shaft is rotatably connected to the mounting hole on the connecting frame 31 so that the fixed pulley 32 can be rotatably connected to the connecting frame 31.

[0097] The second aspect of this application provides a de-icing system, including a de-icing device 5 and a mounting frame for the de-icing device as described in any of the preceding claims; the de-icing device 5 is connected to a traction unit 3; when the hook structure is hooked with the overhead line 4, the traction unit 3 can pull the de-icing device 5 toward the support frame 1 so that the de-icing device 5 abuts against the overhead line 4.

[0098] Specifically, the de-icing device 5 can be a mechanical de-icing device, which includes a housing, an impact column, and a drive mechanism. The impact column is slidably disposed inside the housing, and the drive mechanism is connected to the impact column in a transmission manner, so that the drive mechanism can drive the impact column to reciprocate to impact the housing. The housing is connected to the traction unit 3, which can pull the housing to a position that abuts against the overhead line 4. When the impact column hits the housing, it can transmit the impact force to the ice layer covered by the overhead line 4, causing the ice layer to break and fall off.

[0099] By using the mounting bracket of the de-icing device described above in the de-icing system, after the projectile end crosses the overhead line 4, the support frame 1 can be hooked onto the overhead line 4 by pulling the guide rope. The traction unit 3 then pulls the de-icing device 5 to the overhead line 4 for de-icing operation. This avoids the need for operators to climb to heights and the use of drones to hoist the de-icing device 5.

[0100] When the mounting frame of the de-icing device provided in this application embodiment is used, the operator first throws the throwing end of the guide rope toward the overhead line 4 from a safe position on the ground or at the bottom of the tower, so that the throwing end crosses the overhead line 4 and falls to the ground or operating platform on the other side of the overhead line 4. At this time, the guide rope is laid on the overhead line 4.

[0101] Next, the support frame 1 is hooked to the overhead line 4: the operator pulls the launching end of the guide rope. Since the guide rope is fixed to the connection part 2 of the support frame 1, the tension is transmitted to the connection part 2 through the guide rope, thereby driving the support frame 1 to move towards the overhead line 4 along the extension direction of the guide rope. During the movement, the opening of the hook structure of the support frame 1 always faces the overhead line 4. As the tension is continuously applied, the first bending section 111 abuts against the overhead line 4. The arc-shaped surface of the first bending section 111 guides the overhead line 4 into the opening of the hook structure until the overhead line 4 is completely inside the hook structure. At this time, the support frame 1 is stably hooked to the overhead line 4 through the hook structure. The support frame 1 maintains the connection with the overhead line 4 by relying on the shape limitation of the hook structure and its own weight.

[0102] Then, the de-icing device 5 is installed: The de-icing device 5 is connected and fixed to the traction part 3 on the support frame 1 via its own connecting structure, ensuring a reliable connection. One end of the traction rope is connected to the de-icing device 5, and the other end is held by the operator. The operator applies traction force to the traction rope from the ground or a safe location. The traction force is transmitted to the de-icing device 5 through the traction rope, causing the de-icing device 5 to move towards the support frame 1. During the movement, since the support frame 1 is fixed to the overhead line 4, the de-icing device 5 will not shift until it moves to a position where it contacts the overhead line 4, completing the entire installation process.

[0103] When disassembling the mounting frame, first loosen the traction rope to allow the de-icing device 5 to fall to the ground. Pull the disassembly end of the guide rope to subject the connecting part 2 at one end of the support frame 1 to a force away from the overhead line 4, thereby changing the posture of the arc-shaped support frame 1 and causing the overhead line 4 to disengage from the hook structure of the support frame 1. The launching end is then slowly raised to allow the support frame 1 to slowly descend to the ground.
