Description

Technical Field

[0001] This utility model relates to the field of snow and ice removal technology for power lines, specifically a striking device. Background Technology

[0002] With the increasing frequency of global climate anomalies and extreme weather events, the problem of icing on high-voltage transmission lines and railway contact wires is becoming increasingly serious. Icing and snow accumulation increase the load on high-voltage transmission lines, leading to serious accidents such as line breaks and tower collapses; icing also affects train operations, causing widespread delays or even service disruptions. Currently, although various de-icing methods and devices exist for clearing ice and snow from high-voltage transmission lines, these methods and devices generally suffer from poor de-icing effects, high costs, and complex implementation, and have not yet been widely adopted. For railway contact wires, manual knocking remains the primary method of clearing ice, which is not only inefficient but also poses significant safety hazards. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides the following technical solution: A striking device includes a rotating wheel, a drive shaft, a rotating joint, and a striking rod. The drive shaft is connected to the center of one side of the rotating wheel, and a plurality of rotating joints are rotatably mounted on the edge of the rotating wheel. One end of each rotating joint is connected to a striking rod.

[0004] As a preferred embodiment, the rotating joint consists of a rotating shaft, a male joint head, and a female joint head. The rotating shafts of several rotating joints are evenly distributed and installed on the edge of the rotating wheel. One end of the rotating shaft is fixedly connected to the female joint head or the male joint head, or it can be integrally manufactured with the female joint head or the male joint head. The male joint head or the female joint head is connected to the striking rod. The male joint head is rotatably connected to the female joint head through a pin. The sidewalls of both the male joint head and the female joint head are provided with pin holes that are adapted to the pins.

[0005] As a preferred embodiment, the striking rod consists of a rod body and a connecting rod. The rod body has a cavity extending radially through both ends, and the diameter of the cavity is adapted to the diameter of the connecting rod. The rod body and the connecting rod are rotatably connected through the cavity.

[0006] As a preferred embodiment, the connecting rod has a limiting block at the end away from the joint head, and the rod body has a limiting groove at the end away from the joint head that matches the limiting block, and the limiting groove is connected to the cavity.

[0007] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The striking rod unfolds under the action of centrifugal force to strike the target object, and bounces back in the opposite direction after striking, so that it can pass through the side of the track. The continuous operation is formed by the cyclic action of multiple striking rods, which has high efficiency in clearing ice and snow, and this elastic striking does not damage the track.

[0008] 2. When the extended striking rod touches other existing facilities, it can rotate (tilt) in the opposite direction of travel to avoid damage to existing facilities and striking devices due to rigid collision.

[0009] 3. When the striking rod comes into contact with the target object, it generates a frictional force in the opposite direction of travel. This frictional force drives the rod to rotate around the connecting rod, reducing wear on the rod, increasing the number of stress points on the rod, and extending the service life of the striking rod.

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] Reference Figures 1-4 As shown, a striking device is provided, including a rotating wheel 1, a drive shaft 2, a rotating joint 3, and a striking rod 4. The drive shaft 2 is connected to the center of one side of the rotating wheel 1, and several rotating joints 3 are rotatably installed on the edge of the rotating wheel 1. One end of the rotating joint 3 is connected to the striking rod 4. The rotating wheel 1 is driven to rotate by the drive shaft 2, and the rotating joints 3 and the striking rod 4 rotate accordingly. When a certain speed is reached, under the action of centrifugal force, the striking rod 4 unfolds and strikes the target object, and is then bounced back in the opposite direction. As the rotating wheel passes through the wing side (including the upper side, lower side, left side, right side, side-upper side, side-lower side, etc.) of the target object, each striking rod repeats this action, thereby achieving continuous striking and high work efficiency.

[0014] The rotating joint 3 consists of a rotating shaft 5, a male joint head 7, and a female joint head 6. The rotating shafts 5 in several rotating joints 3 are evenly distributed and installed on the edge of the rotating wheel 1. One end of the rotating shaft 5 is fixedly connected to the female joint head 6 or the male joint head 7, or it can be manufactured integrally with the female joint head 6 or the male joint head 7. The male joint head 7 or the female joint head 6 is connected to the striking rod 4. The male joint head 7 is rotatably connected to the female joint head 6 through a pin 11. The side walls of both the male joint head 7 and the female joint head 6 are provided with pin holes 12 that are adapted to the pin 11. The setting of the rotating joint 3 enables a rotatable connection between the striking rod 4 and the rotating wheel 1. When the unfolded striking rod touches other existing facilities, the striking rod 4 can rotate and tilt flexibly, avoiding damage to both due to rigid collision. As another feasible solution, a "cross shaft" method can also be used to achieve connection and rotation.

[0015] In this example, the striking rod 4 consists of a rod body 9 and a connecting rod 8. The rod body 9 has a cavity 10 that extends through both ends radially inside it, and the diameter of the cavity 10 is adapted to the diameter of the connecting rod 8. The rod body 9 and the connecting rod 8 are rotatably connected through the cavity 10. The rod body 9 can rotate around the connecting rod 8. When the striking rod 4 comes into contact with the target object, it can reduce friction loss, increase the force points, and improve the service life of the striking rod 4 through rotation. As another feasible solution, the striking rod 4 is rotatably connected to the joint head 6, so the rod body 9 does not need to rotate around the connecting rod 8, and the same effect can be achieved.

[0016] In this example, a limiting block 13 is provided at the end of the connecting rod 8 away from the male or female joint 7, and a limiting groove 14 adapted to the limiting block 13 is provided at the end of the rod body 9 away from the male or female joint 7, and the limiting groove 14 is connected to the cavity 10; the cooperation between the limiting block 13 and the limiting groove 14 prevents the rod body 9 from disengaging from the connecting rod 8 during rotation, ensuring the stability and reliability of the striking rod 4 structure.

[0017] During use, the device is installed on a movable carrier, connected to a motor and other power devices, and positioned at an appropriate location on the side of the target object.

[0018] When the drive shaft 2 is subjected to force, it drives the rotating wheel 1 to rotate. The rotating joint 3 on the edge of the rotating wheel 1 rotates accordingly. Initially, the striking rod 4 is in a drooping state. When the rotating wheel 1 reaches a certain speed, the striking rod 4 changes from the initial state to an extended state under the action of centrifugal force. The extended striking rod 4 rotates with the rotating wheel 1 and strikes the target object, such as an icy power line. After the strike, due to the obstruction of the power line, the striking rod 4 is bounced back, causing the rotating wheel 1 to carry the striking rod 4 past the wing side of the target object. The next striking rod 4 repeats the above action, forming continuous striking. When the extended striking rod moves along the extension direction of the target object and touches other existing devices, such as the cup arm of a railway contact network, the hinge structure between the rotating joint 3 and the striking rod 4... The striking rod 4 is tilted and rotated in the opposite direction of travel to avoid damage to existing equipment and striking devices due to rigid collisions. The rod body 9 of the striking rod 4 is sleeved on the connecting rod 8 and can rotate. When the striking rod 4 comes into contact with the target object, the frictional force generated in the opposite direction of travel will cause the rod body 9 to rotate around the connecting rod 8, reducing the frictional loss of the striking rod 4, increasing the force points of the striking rod 4, and effectively improving the service life of the striking rod 4. Since the railway contact line is laid out in a zigzag pattern, multiple striking devices can be set up in parallel to ensure that the contact line is always within the striking range of at least one device. Alternatively, a platform that can move left and right can be loaded on a mobile carrier, and the striking device can be installed on the mobile platform and move with the contact line.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
