Description

Technical Field

[0001] The present invention relates to the technical field of power grid equipment, and specifically to an insulating netting assembly for crossing lines; an insulating anti-falling net for maintaining a sufficient safety distance. Background Art

[0002] During the construction of power grids, equipment for crossing netting operations is often used to enable electric wires to safely cross lines such as highways and railways and ensure safety below the electric wires. Currently, the commonly used netting methods for cross-line construction mainly include scaffolding type, suspension bridge type, double-track propulsion type, rotating arm type, umbrella type, and boom deployment type, etc. Among them, the scaffolding type is the most widely used. For scaffolding type cross-line construction, a crossing frame needs to be erected first, and then a protective net is manually built on the crossing frame for netting operations. This construction method not only has low efficiency but also has relatively large potential safety hazards.

[0003] In the prior art, the Chinese authorized patent publication number: CN 209860475 U, discloses a protective net for crossing construction of transmission lines, including a load-bearing cable, a drag net rope, a nylon net, a pulley, and a clamp. The nylon net is composed of several nylon nets arranged in sequence from left to right to form a nylon net group. Above the outer ends of the two outermost nylon nets between adjacent nylon nets, support pipes are longitudinally arranged. A number of clamps are arranged at intervals along the axial direction on the support pipes. The clamps are connected to the pulleys. A number of hanging rings are arranged on the outer periphery of the nylon net. The hanging rings on the left and right sides of the nylon net are respectively connected to the clamps on the same side. Each hanging ring on the front and rear sides of the nylon net is connected to a pulley respectively. The pulleys on the front and rear sides of the nylon net are respectively installed on the load-bearing cables on the same side. The load-bearing cables are located above the nylon net. Except for the clamps at both ends of the outermost support pipe, which are installed on the load-bearing cables on the same side through pulleys, the other clamps have one end connected to the nylon net and the other end connected to the drag net rope. After the drag net rope and the load-bearing cable bypass the crossing frame, they are anchored on the ground. This protective net is very convenient for hanging and removing the net and has a long service life; however, the composition of this prior art is complex and there are potential safety hazards during the operation process.

One end of the second wire reel 18 is fixedly connected to the first fixed buckle 21, and the other end of the second wire reel 18 is connected to the second fixed buckle 24.

[0033] The fourth fixed buckle 24 is arranged at the left end of the second sub-rod 14. The right side of the second sub-rod 14 is designed with an opening and nests the third sub-rod 15. A third wire reel group 19 for extension and contraction actions is arranged on the right side of the first sub-rod 14. One end of the third wire reel 19 is fixedly connected to the second fixed buckle 22, and the other end of the third wire reel 19 is connected to the third fixed buckle 25.

[0034] The fifth fixed buckle 25 is arranged at the left end of the third sub-rod 15. The right side of the third sub-rod 15 is designed with an opening and nests the fourth sub-rod 16. A fourth wire reel group 20 for extension and contraction actions is arranged on the right side of the third sub-rod 15. One end of the fourth wire reel 20 is fixedly connected to the third fixed buckle 23, and the other end of the fourth wire reel 20 is connected to the sixth fixed buckle 26.

[0035] The sixth fixed buckle 26 is arranged at the left end of the fourth sub-rod 16. A guy rope storage reel 9 is arranged at the upper right end of the fourth sub-rod 16.

[0036] Preferably, the main rod 12, the first sub-rod 13, the second sub-rod 14, the third sub-rod 15, and the fourth sub-rod 16 are nested in sequence, which is convenient for carrying and can be expanded or scaled according to actual construction needs.

[0037] The telescopic rod 4 is made of fiberglass - reinforced plastic material.

[0038] As Figure 2 As shown in the figure, it shows a schematic structural diagram of the insulating net and the telescopic rod of the present invention, including a support and fixing assembly, a telescopic rod 4, and a net 7.

[0039] The support and fixation assembly includes guy ropes 1, balance rods 2, support rods 5, cross bars 3, and weight hanging ropes 6;

[0040] Two support rods 5 with the same structure and size form a support and fixation group. The support and fixation group is vertically installed on the ground. The upper ends of the support rods 5 in the support and fixation group are fixedly connected to the cross bar 3. The telescopic rod 4 is horizontally and fixedly placed on the cross bar 3 of the support and fixation group. The balance rod 2 is vertically installed at the left end of the telescopic rod 4. A guy rope storage tray 9 is arranged at the upper end of the balance rod 2. One end of the weight hanging rope 6 is fixedly installed at the upper end of the balance rod 2, and the other end of the weight hanging rope 6 hangs vertically in the air;

[0041] Hooks 8 are arranged on both long sides of the net enclosure 7, and the net enclosure 7 is fixedly connected to the telescopic rod 4 through the hooks 8;

[0042] The length of the main rod 12 is 4 meters, and the lengths of the first sub-rod 13, the second sub-rod 14, the third sub-rod 15, and the fourth sub-rod 16 are all 3 meters. The advantage is that the length of the telescopic rod 4 can be adjusted according to actual construction requirements, and the length adjustment between 4 meters and 12 meters can be achieved.

[0043] In specific implementation, the staff first vertically installs two groups of the support and fixation assemblies around the line to be crossed, then fixes the telescopic rod 4 above the cross bar, extends two insulated telescopic rods 4 to the designated position according to the length to be crossed, uses the winch 11 at the lower end of the main rod 12 to sequentially pull out the first sub-rod, the second sub-rod, the third sub-rod, and the fourth sub-rod, and then fixedly connects the net enclosure 7 through the hooks 8, thereby forming an insulated anti-falling safety net that maintains a sufficient safety distance from the crossed road and conductors below 10 kV. The guy rope storage tray at the upper end of the telescopic rod 4 will be adjusted as the sub-rod extends or shortens in length, so that during the use of the telescopic rod, it will not swing randomly in strong wind weather, thus affecting the construction of the staff. At the same time, the upper end of the telescopic rod 4 is equipped with the weight hanging rope 6, which ensures the stability of the telescopic rod 4 during use, and to a certain extent, ensures construction safety and eliminates potential safety hazards.

[0044] Among them, the telescopic rod 4 adopts a multi-section nested design, and realizes fast and stable telescopic adjustment through a precise locking mechanism. According to actual operation requirements, the rod body length can be easily adjusted to cover the operation range from several meters to dozens of meters. During the telescopic process, the rod body maintains good stability and is not easy to shake, ensuring the accuracy and safety of the operation.

[0045] The telescopic rod 4 is made of high-strength glass fiber-reinforced plastic material, and the mesh cover 7 is made of insulating material. These materials have excellent electrical insulation performance and mechanical strength, can effectively resist current leakage in a high-voltage environment, and ensure the safety of operators. In addition, the surface of the insulating layer has been specially treated to improve wear resistance and anti-aging performance, ensuring the reliability and safety of long-term use.
