Description

Technical Field

[0001] This application relates to the technical field of network closing devices, and particularly to a peristaltic alternating power transmission line network closing device and a control method. Background Art

[0002] During the erection and crossing construction process of power transmission lines, it is often encountered that important facilities need to be crossed, and it shows characteristics such as increasing crossing height, increasing number of times, and increasingly complex working conditions. When crossing important facilities, it is necessary to carry out network closing protection for the newly built line. However, in actual construction, the management unit of the facility to be crossed gives the construction unit very little time for network closing. Whether it can be safely and quickly closed within a limited time has become a key task.

[0003] The existing power transmission line maintenance net laying is carried out by traditional manual laying, which makes the construction period of power transmission line maintenance net laying long, the labor intensity of the net laying personnel large, and the laying, disassembly and recycling of the insulating net very troublesome.

[0004] In addition, the current mainstream network closing devices mainly rely on materials such as steel pipes, guy wires, drilled piles, and insulating ropes to build, and there are the following problems:

[0005] (1) Large consumption of materials and manpower: A large amount of labor and materials are required during the building process, with low efficiency and high cost;

[0006] (2) Limited applicable scenarios: For example, the network closing device mentioned in the comparative document CN118712948A is huge in volume and depends on flat ground environment, and it is difficult to adapt to complex terrains such as the wild and dense trees;

[0007] (3) Heavy load and difficult to tow: The weight of a general insulating net is as high as dozens of kilograms. The electric direct drive walking wheels are likely to slip and idle on the rope due to insufficient migration force, which not only damages the walking wheels, but also damages the rope guide rails, and is prone to cause safety accidents. For example, in the power transmission line crossing protection net erection device mentioned in the patent application CN117748366A and the walking mechanism applicable to the power transmission line crossing protection net erection device mentioned in the patent application CN117748356A, the walking wheels all have varying degrees of slipping. Summary of the Invention

[0008] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, this application proposes a peristaltic alternating power transmission line network closing device and a control method, which can improve the efficiency and safety of network closing operations.

[0009] An embodiment of the first aspect of the present application provides a peristaltic alternating power transmission line network sealing device, which includes two walking parts arranged at a certain angle and a walking driving mechanism. Each walking part includes a bracket, a walking wheel and a brake block. The walking wheel is rotatably installed on the bracket. The walking wheel is used to abut against the cable. The brake block is spaced on one side of the walking wheel. The brake block and the walking wheel enclose a matching space for accommodating the cable. The brake block can move towards or away from the side of the walking wheel. The walking driving mechanism is used to change the angle between the two walking parts so that the walking parts move along the cable.

[0010] Further, a first groove is formed in the middle of the walking wheel, and the first groove is used to abut against the cable.

[0011] Further, a locking mechanism is further included, and the locking mechanism is used to lock the walking wheel to limit the rotation of the walking wheel.

[0012] Further, a second groove is provided on the side of the brake block close to the walking wheel, and the second groove is used to cooperate with the cable.

[0013] Further, a lifting mechanism is further included. The lifting mechanism is installed on the bracket, and the lifting mechanism is used to drive the brake block to lift so as to drive the brake block to move.

[0014] Further, the lifting mechanism includes a movable block and a lifting module. The brake block is installed on the movable block, and the lifting module is used to drive the movable block to move so as to drive the brake block to move.

[0015] Further, the brake block is rotatably connected to the movable block, and the rotation axis of the brake block relative to the movable block is parallel to the rotation axis of the walking wheel.

[0016] Further, the lifting module includes a lead screw, a guide rod and a driving member. The lead screw cooperates with the movable block, and the movable block is slidably connected to the guide rod. The driving member drives the lead screw to rotate so as to drive the movable block to move relative to the lead screw.

[0017] Further, an avoidance groove is provided on the bracket. The brake block is arranged on one side of the bracket, and the driving member, the guide rod and the lead screw are all arranged on the other side of the bracket. One end of the movable block is connected to the lead screw, and the other end of the movable block passes through the avoidance groove and is connected to the brake block.

[0018] An embodiment of the second aspect of the present application provides a control method, which is applied to the peristaltic alternating power transmission line network sealing device as described above. Among them, the two walking parts are respectively denoted as a first walking part and a second walking part, and the method includes the following steps:

[0019] Sheath the mating space of the first traveling part and the second traveling part around the outer periphery of the cable.

[0020] Set the included angle between the first traveling part and the second traveling part to a first angle. At the same time, the brake blocks of both the first traveling part and the second traveling part abut against the cable.

[0021] Move the brake block of the second traveling part away from the cable. Adjust the included angle between the first traveling part and the second traveling part to a second angle through the traveling driving mechanism. The second angle is smaller than the first angle.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] See Figure 1As shown in the figure, an embodiment of the first aspect of the present application discloses a peristaltic alternating power transmission line network sealing device, which includes two traveling parts 100 arranged at a certain angle and a traveling driving mechanism 200. Each traveling part 100 includes a bracket 110, a traveling wheel 120 and a brake block 130. The traveling wheel 120 is rotatably installed on the bracket 110. The traveling wheel 120 is used to abut against the cable 1. The brake block 130 is arranged at intervals on one side of the traveling wheel 120. The brake block 130 and the traveling wheel 120 enclose a fitting space for accommodating the cable 1. The brake block 130 can move towards the side close to or away from the traveling wheel 120. The traveling driving mechanism 200 is used to change the angle between the two traveling parts 100 so that the traveling parts 100 move along the cable 1.

[0039] In this embodiment, referring to Figure 4 and Figure 5 , for the convenience of description, the two traveling parts 100 are respectively denoted as the first traveling part 161 and the second traveling part 162. In the figure, the X direction is the forward direction of the network sealing device. The first traveling part 161 is in the front and the second traveling part 162 is in the back. In actual application, the fitting spaces of the first traveling part 161 and the second traveling part 162 are sleeved on the outer periphery of the cable 1; then the angle between the first traveling part 161 and the second traveling part 162 is set at a first angle. At the same time, the brake blocks 130 of the first traveling part 161 and the second traveling part 162 both abut against the cable 1; then the brake block 130 of the second traveling part 162 moves away from the cable 1, and the angle between the first traveling part 161 and the second traveling part 162 is adjusted to a second angle through the traveling driving mechanism 200. The second angle is smaller than the first angle. Then the brake block 130 in the second traveling part 162 moves towards the cable 1 to clamp the cable 1; then the brake block 130 of the first traveling part 161 moves away from the cable 1, and the angle between the first traveling part 161 and the second traveling part 162 is adjusted to a third angle through the traveling driving mechanism 200. The third angle is larger than the second angle. Then the brake block 130 in the first traveling part 161 moves towards the cable 1 to clamp the cable 1; repeat the above steps until the peristaltic alternating power transmission line network sealing device moves to the target position.

[0040] In the peristaltic alternating power transmission line network sealing device provided by the embodiments of the present application, through the peristaltic movement of two traveling parts 100 in an alternating manner, combined with the brake blocks 130 on the two traveling parts 100 alternately clamping or loosening the cable 1, the network sealing device can move along the extension direction of the cable 1, and can drag the insulating net to the target position. In the embodiments of the present application, the network sealing device is easy to install, can complete the network sealing operation quickly and safely, greatly improves the efficiency of the network sealing operation, reduces the labor intensity of the network sealing operation, and also improves the safety of the network sealing operation. At the same time, in this embodiment, the network sealing device is small in size, can adapt to complex terrains such as the wild and dense trees, and has a wide range of usage scenarios.

[0041] In some embodiments of the present application, referring to Figure 1 and Figure 2 , a first groove 121 is formed in the middle of the traveling wheel 120, and the first groove 121 is used to abut against the cable 1. In actual work, at least a part of the cable 1 is located in the first groove 121, which can reduce the situation of the cable 1 breaking away from the traveling wheel 120, and is beneficial to ensuring the operation safety and operation efficiency. At the same time, by providing the first groove 121 in the traveling wheel 120, the contact area between the traveling wheel 120 and the cable 1 can be increased. When the brake block 130 clamps the cable 1, the cable 1 can be clamped with a relatively small acting force, avoiding loosening between the cable 1 and the traveling wheel 120 or the brake block 130. In addition, due to the setting of the first groove 121, the network sealing device can be installed on the cable 1 without using a limiting member, which is beneficial to simplifying the installation structure of the network sealing device.

[0042] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the network sealing device further includes a locking mechanism 140, and the locking mechanism 140 is used to lock the traveling wheel 120 to limit the rotation of the traveling wheel 120. When it is necessary to relatively fix the traveling wheel 120 and the cable 1, the locking mechanism 140 can be used to limit the rotation of the traveling wheel 120 to achieve braking, so as to reduce the probability of the traveling wheel 120 moving relative to the cable 1.

[0043] In a possible implementation manner, the locking mechanism 140 includes a brake, and the brake is installed on the bracket 110 and is used to lock and brake the traveling wheel 120.

[0044] It should be understood that the locking mechanism 140 may also be some other structures that can limit the rotation of the traveling wheel 120, which is not limited herein.

[0045] In some embodiments of the present application, a second groove is provided on the side of the brake block 130 close to the traveling wheel 120, and the second groove is used to cooperate with the cable 1. In this way, the situation of brake failure of the brake block 130 can be reduced.

[0046] In some embodiments of the present application, referring toFigure 1 and Figure 2 The net closing device further includes a lifting mechanism which is installed on the bracket 110 and is used to drive the brake block 130 to lift so as to drive the brake block 130 to move. Among them, through the action of the lifting mechanism, the brake block 130 can be driven to move towards or away from the traveling wheel 120, so as to clamp or loosen the cable 1.

[0047] In a possible implementation manner, referring to Figures 1 to 3 , the lifting mechanism includes a movable block 151 and a lifting module. The brake block 130 is installed on the movable block 151, and the lifting module is used to drive the movable block 151 to move so as to drive the brake block 130 to move.

[0048] Among them, the lifting module can be a cylinder, an electric cylinder or a driving mechanism with a lead screw slider structure.

[0049] In this embodiment, please continue to refer to Figures 1 to 3 , the lifting module includes a lead screw 1521, a guide rod 1522 and a driving member 1523. The lead screw 1521 cooperates with the movable block 151, and the movable block 151 is slidably connected to the guide rod 1522. The driving member 1523 drives the lead screw 1521 to rotate so as to drive the movable block 151 to move relative to the lead screw 1521. Among them, the driving member 1523 is specifically a driving motor, and the driving motor drives the lead screw 1521 to rotate through a transmission member so as to drive the movable block 151 to move along the axial direction of the lead screw 1521.

[0050] Further, referring to Figure 3 , the lifting module includes a mating block 1524 which is provided with a threaded hole for mating with the lead screw 1521. Among them, the mating block 1524 is connected to one end of the movable block 151.

[0051] When the intersection angle between the two traveling parts 100 changes, the relative angle between the surface of the brake block 130 and the cable 1 will also change accordingly. Therefore, in some embodiments of the present application, please refer to Figure 3 , the brake block 130 is rotatably connected to the movable block 151, and the rotation axis of the brake block 130 relative to the movable block 151 is parallel to the rotation axis of the traveling wheel 120. Among them, Figure 3 in, a represents the rotation axis of the brake block 130 rotating relative to the movable block 151. When the angle between the two traveling parts 100 changes, the brake block 130 can rotate around the rotation axis a so that the surface of the brake block 130 is parallel to the cable 1. In this way, the contact area between the brake block 130 and the cable 1 can be ensured, thereby ensuring the clamping effect.

[0052] Further, referring to Figure 2 and Figure 3, the lifting module includes a connecting block 153. The connecting block 153 is connected to the bracket 110, and the lead screws 1521 and 1522 are rotatably connected to the connecting block 153.

[0053] In some embodiments of the present application, refer to Figures 1 to 3 , the bracket 110 is provided with an avoidance groove. The brake block 130 is arranged on one side of the bracket 110, and the driving member 1523, the guide rod 1522, and the lead screw 1521 are all arranged on the other side of the bracket 110. One end of the movable block 151 is connected to the lead screw 1521, and the other end of the movable block 151 passes through the avoidance groove and is connected to the brake block 130. That is to say, components such as the driving member 1523, the guide rod 1522, and the lead screw 1521 will not interfere with the brake block 130 and the movable block 151, which is beneficial to reducing the overall volume of the net sealing device and can improve the portability of the net sealing device in this embodiment. At the same time, within the effective volume, the moving stroke of the brake block 130 and the movable block 151 can be increased, which is beneficial to increasing the change range of the included angle between the two traveling parts 100, helps to achieve large-angle peristalsis, improves the moving efficiency, and thus improves the net sealing effect.

[0054] In some embodiments of the present application, the traveling driving mechanism 200 includes a driving motor. The driving motor is installed on one of the brackets 110, and the output end of the driving motor is connected to the bracket 110 of the other traveling part 100. By controlling the driving motor to rotate forward or backward by a certain angle, the included angle between the two traveling parts 100 can be changed, so as to achieve alternating peristaltic forward movement.

[0055] It should be understood that the traveling driving mechanism 200 in the embodiments of the present application may also be other driving mechanisms that can change the relative included angle between the traveling parts 100, which is not limited herein.

[0056] In some embodiments of the present application, the net sealing device includes a fixing mechanism 300. The fixing mechanism 300 is used to connect with the insulating net and is used to tow the insulating net to move on the cable 1 to achieve the net sealing operation.

[0057] In an application scenario, the net sealing device is used to tow the insulating net to move on the cable 1 to achieve the net sealing operation, as Figure 4 shown.

[0058] The embodiments of the second aspect of the present application disclose a control method, which is applied to the peristaltic alternating power transmission line net sealing device as described above. Among them, the two traveling parts 100 are respectively denoted as the first traveling part 161 and the second traveling part 162, and the method includes the following steps:

[0059] Set the cooperation space of the first traveling part 161 and the second traveling part 162 around the outer circumference of the cable 1;

[0060] Set the included angle between the first traveling part 161 and the second traveling part 162 to a first angle. At the same time, the brake blocks 130 of the first traveling part 161 and the second traveling part 162 are both in contact with the cable 1;

[0061] Move the brake block 130 of the second traveling part 162 in a direction away from the cable 1. Adjust the included angle between the first traveling part 161 and the second traveling part 162 to a second angle through the traveling driving mechanism 200. The second angle is smaller than the first angle. Then move the brake block 130 in the second traveling part 162 in a direction close to the cable 1 to clamp the cable 1;

[0062] Move the brake block 130 of the first traveling part 161 in a direction away from the cable 1. Adjust the included angle between the first traveling part 161 and the second traveling part 162 to a third angle through the traveling driving mechanism 200. The third angle is larger than the second angle. Then move the brake block 130 in the first traveling part 161 in a direction close to the cable 1 to clamp the cable 1;

[0063] Repeat the above steps until the peristaltic alternating power transmission line network sealing device moves to the target position.
