Description

Technical Field

[0001] This utility model belongs to the field of power construction equipment, specifically a multi-functional combined contact network long foreign object handling device. Background Technology

[0002] The overhead contact system of electrified railways is the core power supply system providing electricity to electric locomotives. However, along railway lines, long foreign objects often become entangled in the contact system due to natural or man-made factors. "Long foreign objects in the contact system" refers to large objects suspended or wrapped around the railway contact system. The presence of such foreign objects directly threatens the reliability of the contact system's power supply and operational safety, causing safety issues such as short-circuit tripping, mechanical damage to the contact system, and fire risks.

[0003] Foreign objects growing on overhead contact lines are diverse and can be classified into natural and man-made objects based on their source, material, and physical characteristics. Natural objects include bird nests and tree branches, while man-made objects include kites, plastic sheeting, and tangled ropes.

[0004] Currently, the removal of long foreign objects from overhead contact lines mainly relies on manual pole climbing or simple mechanical tools. However, this method has several drawbacks: First, it is limited in function and has a narrow scope of application. Existing cleaning equipment is mostly specialized and can only handle specific types of foreign objects. For example, the combination of a traditional insulating pole and hook device is only suitable for grabbing small, hard foreign objects; while hydraulic pruning machines can cut tree branches, they cannot handle lightweight kites or tightly tangled nylon ropes. Second, it is inefficient and carries high safety risks. Manual pole climbing requires power outages and protective measures, is greatly limited by weather and terrain, and poses a risk of falls from heights.

[0005] In summary, existing cleaning methods cannot meet the needs for efficient and safe cleaning of diverse long foreign objects in overhead contact lines. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model aims to provide a multifunctional combined contact wire long foreign object handling device to achieve targeted handling of different types of foreign objects, thereby improving emergency repair efficiency and power supply reliability.

[0012] The combustion processor includes a fuel tank, a burner nozzle connected to the fuel tank, and an ignition switch, wherein the bottom of the fuel tank is detachably connected to the top of an insulating rod.

[0013] As a limitation of this utility model: the plurality of burrs and the plurality of bristles are all made of steel wire, and the strength and toughness of the bristles are less than those of the burrs.

[0014] As a further limitation of this utility model: a number of anti-slip protrusions are provided on the outer wall of the bottom end of the insulating rod.

Detailed Implementation

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0036] like Figures 1 to 7 As shown, this embodiment includes an insulating rod 1 and a foreign object processor detachably mounted on the top of the insulating rod 1. The foreign object processor can be any one of a spiked club processor 2, a wire brush processor 3, a cutter processor 4, or a combustion processor 5. When in use, the appropriate foreign object processor is selected according to the type of foreign object to be cleaned and installed on the top of the insulating rod 1.

[0037] 1. Insulating rod;

[0038] The use of insulating rod 1 can prevent the risk of electric shock to construction workers when cleaning long foreign objects from the contact wire. The structure of insulating rod 1 is existing technology and will not be described in detail in this embodiment. Figure 1 , 3 As shown in Figure 4, in this embodiment, several anti-slip protrusions 6 are provided on the outer wall of the bottom end of the insulating rod 1, that is, at the position where the hand grips the insulating rod 1, to increase the friction between the hand and the insulating rod 1.

[0039] II. Wolf Fang Mace Processor 2;

[0040] like Figure 1 , 2 As shown, the spiked club processor 2 includes a rod body 21 detachably connected to the top of the insulating rod 1, and several burr portions 22 fixed on the rod body 21. The burr portions 22 are densely distributed in both the circumferential and axial dimensions of the rod body 21 and extend outwards in a divergent structure, forming a radial structure. That is, one end of each burr portion 22 is fixedly connected to the rod body 21, and the other end extends radially outwards from the surface of the rod body 21. The spiked club processor 2 is similar in appearance to a curling comb, greatly increasing the effective contact area and entanglement points with foreign objects.

[0041] Several burrs 22 are made of high-strength, high-toughness steel wire, which can withstand greater impact and torsion when removing large foreign objects. They have extremely high resistance to bending, deformation and breakage, which significantly improves the service life of the spiked club processor 2.

[0042] For foreign objects with a certain degree of toughness and a large surface area, such as plastic sheeting or kites, the spiked club processor 2 in this embodiment has a highly efficient handling capability. The burrs 22 can pierce the surface of such foreign objects. Once pierced, the numerous burrs 22 arranged in a divergent pattern will work together to effectively hook and entangle the foreign object during subsequent dragging, lifting, or rotating operations, making it easy to safely and thoroughly remove it from the contact wire.

[0043] 3. Wire brush processor 3;

[0044] like Figure 5 As shown, the wire brush processor 3 includes a brush roller 31 detachably connected to the top of the insulating rod 1, and a plurality of brush filaments 32 spirally wound and fixed on the surface of the brush roller 31. The plurality of brush filaments 32 are distributed in a spiral staircase shape along the circumferential direction and axial direction of the brush roller 31, and the plurality of brush filaments 32 extend in a direction away from the brush roller 31 to form a divergent structure.

[0045] Several bristles 32 are made of thin-diameter steel wire, and the strength and toughness of these bristles 32 are less than the burrs 22 of the spiked club processor 2. This structure gives the bristles 32 a powerful gripping ability; once a foreign object comes into contact, it is simultaneously hooked by the bristles 32 in multiple directions. The wire brush processor 3 can firmly grasp small pieces of foreign objects such as thin plastic sheets, ensuring that the foreign object will not fall off during the removal process. This solves the problem of insufficient gripping power for small, thin foreign objects by traditional removal tools, greatly improving work efficiency.

[0046] IV. Cutting Processor 4;

[0047] like Figure 6 As shown, the cutter processor 4 includes a fixed rod 41 detachably connected to the top of the insulating rod 1, and a cutter 42 fixed on the fixed rod 41, with the blade of the cutter 42 facing the ground. A hook 43 is also fixed on the fixed rod 41, with the hook 43 and the cutter 42 located on opposite sides of the fixed rod 41. The hook 43 includes a hook arm 431 and a hook head 432, with the hook arm 431 bent downwards and the hook head 432 facing the ground.

[0048] The structure of the aforementioned fixing rod 41, cutter 42, and hook 43 is prior art, as detailed in patent publication number CN214204651U. Its structure will not be described in detail here; only the positions of the cutter 42 and hook 43 are modified in this embodiment. The cutter processor 4 is used to cut and hook off branches, bird nests, or other similar types of foreign objects.

[0049] V. Combustion Processor 5;

[0050] like Figure 7As shown, the combustion processor 5 includes a fuel tank 51, a nozzle connected to the fuel tank 51, and an ignition switch 52. A windproof tube 53 for protecting the flame is fixedly sleeved around the nozzle. The bottom of the fuel tank 51 is detachably connected to the top of the insulating rod 1. The combustion processor 5 is prior art; for details, please refer to patent publication number CN209233314U. Its structure will not be described in detail here.

[0051] The combustion processor 5 is used to burn foreign objects entangled in the corners of the contact wire that cannot be removed by other foreign object processors, thereby achieving carbonization and coking of the foreign objects. The design of the windproof pipe 53 ensures that the operation effect will not be affected by external wind interference when performing flame burning operations on foreign objects in the field, fully guaranteeing safety and work efficiency.

[0052] It should be added that, such as Figure 1 , 3 As shown, the insulating rod 1 is detachably connected to the foreign matter processor via a connector 7, while the insulating rod 1 is fixedly connected to the connector 7. The connector 7 and the foreign matter processor are connected via a plug-in connection. In this embodiment, the connector 7 is a quick connector. A connector head 8 adapted to the quick connector is fixed to the bottom of the rod body 21, brush roller 31, fixing rod 41, and fuel tank 51. The structure of the quick connector and connector head 8, as well as their plug-in connection method, are existing technologies and will not be described in detail in this embodiment. The plug-in connection structure facilitates shorter replacement time for the foreign matter processor.

[0053] When using this embodiment, a suitable foreign object processor is selected and installed on the top of the insulating rod 1 according to the type of foreign object to be removed. If different types of foreign objects are encountered during the cleaning process, the current foreign object processor can be quickly removed from the insulating rod 1 and replaced with another suitable foreign object processor. This embodiment meets the needs for efficient and safe cleaning of diverse long foreign objects in overhead contact lines.

[0054] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
