Description
Technical Field
[0001] This utility model relates to the field of overhead contact line technology, specifically to a composite tool for removing foreign objects from overhead contact lines. Background Technology
[0002] The overhead contact system is a high-voltage power transmission line that runs in a zigzag pattern above the rails in electrified railways, supplying current to the pantograph. It is the main framework of railway electrification projects and a special type of power transmission line that supplies electricity to electric locomotives. It consists of several parts: contact suspension, support devices, positioning devices, pillars, and foundations. During daily use, the overhead contact system may encounter foreign objects such as bird droppings or ice. Over time, this increases the load on the contact system and causes corrosion. Timely cleaning is necessary; otherwise, it will affect the normal operation of the electrified railway.
[0003] However, the following problems exist in the methods and operations for cleaning foreign objects from the overhead contact line: Typically, workers primarily use specialized foreign object removal rods to clean the contact line. The methods involve either striking the contact line with a rod equipped with a T-hook to remove the foreign objects through direct contact or vibration, or scraping with a specially designed single-sided serrated blade head. However, in actual cleaning, workers often need to hold the removal tools for extended periods. Due to the height of the contact line and the length and weight of the removal rods, the labor intensity is high. Furthermore, existing removal heads can only clean from one side, resulting in low efficiency and poor removal effectiveness. Therefore, it is necessary to design corresponding technical solutions to address these technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a composite tool for removing foreign objects from overhead contact lines, which solves the technical problems of workers having to continuously hold up the tool for a long time to remove foreign objects from the contact line when cleaning foreign objects with a special foreign object cleaning rod, resulting in high labor intensity, and the cleaning head only being able to clean foreign objects on one side, resulting in low efficiency and poor cleaning effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite tool for removing foreign objects from overhead contact lines, comprising an insulating rod, a handle, a mounting base, a cleaning head, and an adjustment assembly. The upper and lower ends of the insulating rod are respectively connected to the mounting base and the handle. The surface of the handle is machined with a floating groove. The cleaning head is mounted on the mounting base and includes a hook, cleaning plates, and a compression spring. The inner wall of the hook has two symmetrically arranged mounting openings. The cleaning plates are arranged in two groups, with the lower ends of the two groups of cleaning plates rotatably connected to the inner wall of the mounting openings and the upper ends... The end is movable at the top of the hook. One end of the compression spring is connected to the inner wall of the hook and the other end is connected to the cleaning plate. The top of the hook is also provided with a movable groove. The adjustment assembly includes a floating plate, a traction rope, a guide wheel and an adjustment wheel. The floating plate is slidably disposed in the floating groove. The inner end of the floating plate is connected to the traction rope. The traction rope is laid along the insulating rod and its upper end passes through the guide wheel and is connected to the adjustment wheel. The guide wheel is installed on one side of the hook. The adjustment wheel is built into the movable groove. The adjustment wheel is used in conjunction with two sets of cleaning plates.
[0006] In a preferred embodiment of this utility model, both sets of cleaning blades include an arc-shaped plate and a scraper fixed to the inner side of the middle of the arc-shaped plate. The upper end of the arc-shaped plate has a spherical structure, and a cleaning cavity is formed between the two sets of scrapers.
[0007] In a preferred embodiment of this invention, the scraper is made of hard rubber material and has a blade-shaped edge.
[0008] In a preferred embodiment of this utility model, the adjusting wheel includes a rotating wheel, a toggle block, a traction block, and a pin. The rotating wheel is built into the top of the hook. The toggle block is divided into two groups and installed on the edge of the rotating wheel. The traction block is fixed to the upper end of the rotating wheel and connected to the traction rope. The pin is fixed to the hook and its inner end is connected to the middle of the rotating wheel.
[0009] In a preferred embodiment of this utility model, the actuating block has a fan-shaped structure with one end being narrower than the other end, and the actuating block is in contact with the upper end of the arc-shaped plate.
[0010] In a preferred embodiment of this utility model, the pin includes a connecting rod and a torsion spring fixed to the inner end of the connecting rod, wherein the inner end of the torsion spring is connected to the center of the rotating wheel.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model optimizes the structure of the existing contact wire foreign object cleaning rod by equipping it with an adjustment component. When it is necessary to clean foreign objects on the contact wire, the operator can adjust the spacing between the cleaning blades on the upper cleaning head through the adjustment component, so that the two sets of cleaning blades can make better contact with the contact wire and achieve cleaning, which greatly improves the cleaning efficiency of foreign objects.
[0013] 2. This utility model has redesigned and modified the existing contact wire foreign object cleaning rod cleaning head, cleverly designing it into a hook-shaped cleaning head, so that the contact wire working rod can hook vertically onto the contact wire. The operator only needs to exert force along the longitudinal direction of the contact wire, without having to provide the force to lift the contact wire foreign object cleaning rod for a long time, which greatly reduces the labor intensity of the operator.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a composite tool for removing foreign objects from overhead contact lines, comprising an insulating rod 1, a handle 2, a mounting base 3, a cleaning head 4, and an adjustment assembly. The upper and lower ends of the insulating rod 1 are respectively connected to the mounting base 3 and the handle 2. The surface of the handle 2 is machined with a floating groove 5. The cleaning head 4 is mounted on the mounting base 3 and includes a hook 6, cleaning plates 7, and a compression spring 8. The inner wall of the hook 6 has two sets of mounting openings symmetrically provided. The cleaning plates 7 are divided into two sets, with the lower ends of the two sets of cleaning plates 7 rotatably connected to the inner wall of the mounting openings 9 and the upper ends movably mounted on the hook 6. At the top, one end of the compression spring 8 is connected to the inner wall of the hook 6 and the other end is connected to the cleaning plate 7. The top of the hook 6 is also provided with a movable groove. The adjustment assembly includes a floating plate 10, a traction rope 11, a guide wheel 12 and an adjusting wheel 13. The floating plate 10 is slidably disposed in the floating groove 5. The inner end of the floating plate 10 is connected to the traction rope 11. The traction rope 11 is laid along the insulating rod 1 and its upper end passes through the guide wheel 12 and is connected to the adjusting wheel 13. The guide wheel 12 is installed on one side of the hook 6. The adjusting wheel 13 is built into the movable groove. The adjusting wheel 13 is used in conjunction with two sets of cleaning plates 7.
[0021] Further improvements, such as Figure 2 As shown, both sets of cleaning blades 7 include an arc-shaped plate 14 and a scraper 15 fixed to the inner side of the middle part of the arc-shaped plate 14. The upper end of the arc-shaped plate 14 has a spherical structure, and a cleaning cavity 16 is formed between the two sets of scrapers 15. The cleaning blades 7 are used to clean foreign objects on the surface of the contact wire.
[0022] Further improvements, such as Figure 2 As shown, the scraper 15 is made of hard rubber material and has a blade-shaped edge. This design makes it easy to remove foreign objects from the surface of the contact wire using the scraper 15.
[0023] Further improvements, such as Figure 4 As shown, the adjusting wheel 13 includes a rotating wheel 17, a toggle block 18, a traction block 19, and a pin 20. The rotating wheel 17 is built into the top of the hook 6. The toggle block 18 is divided into two groups and installed on the edge of the rotating wheel 17. The traction block 19 is fixed to the upper end of the rotating wheel 17 and connected to the traction rope 11. The pin 20 is fixed to the hook 6 and its inner end is connected to the middle of the rotating wheel 17. The traction rope 11 pulls the traction block 19, causing the rotating wheel 17 to rotate and the toggle block 18 to act on the cleaning plate 7.
[0024] Further improvements, such as Figure 4 As shown, the actuating block 18 has a fan-shaped structure with one end being narrower than the other. The actuating block 18 contacts the upper end of the arc plate 14. By actuating the block 18, the spacing between the two sets of cleaning plates 7 can be adjusted.
[0025] Specifically, the pin 20 includes a connecting rod 21 and a torsion spring 22 fixed to the inner end of the connecting rod 21. The inner end of the torsion spring 22 is connected to the center of the rotating wheel 17, which facilitates the rotation of the rotating wheel 17.
[0026] In use: When it is necessary to clean the dirt on the surface of the contact wire, the operator presses down the floating plate 10 with his / her finger. The floating plate 10 acts on the traction rope 11, and the traction rope 11 pulls the traction block 19 to rotate counterclockwise. During the rotation, the rotating wheel 17 rotates around the pin 20 and acts on the cleaning plate 7 through the actuating block 18, so that the distance between the two sets of cleaning plates 7 is increased. At this time, the cleaning head 4 is placed at the dirt position of the contact wire, so that the contact wire is located in the cleaning chamber 16. Then, the pressure on the floating plate 10 is slowly reduced. Under the action of the torsion spring 22 and the compression spring 8, the two sets of cleaning plates 7 rotate inward, so that the scraper 15 contacts the surface of the contact wire. At this time, the operator pulls the foreign matter cleaning rod horizontally, and the scraper 15 peels off the foreign matter attached to the surface of the contact wire. The operation is simple and easy to use.
