Technical Field
[0001] This application relates to the field of railway transportation EMU applications, and in particular to a multi-purpose linker for EMUs. Background Technology
[0002] Link rods are used in railways to remove foreign objects from the pantographs on the roofs of high-speed trains, including those that have frozen or damaged the pantographs or have attached cables. This ensures the safe operation of high-speed trains and facilitates the timely restoration of railway transport order. However, existing link rods have a "T"-shaped working component. These design flaws present challenges when removing lightweight objects, bird carcasses, and other debris from high-voltage components on train roofs or platforms. These issues include inconvenience, inability to meet the requirements of certain railway operating environments, the risk of objects falling back during operation, and the inability to remove some objects completely. Consequently, these methods are time-consuming and ineffective. Summary of the Invention
[0003] In view of this, this application provides a multi-purpose linker for high-speed trains, which has a good effect on removing foreign objects.
[0004] To achieve the above objectives, this application employs the following technical solution:
[0005] A multi-purpose linker for high-speed trains is characterized by comprising a support rod and a working head fixedly mounted on the support rod. The working head includes a vertically arranged intermediate rod and horizontal rods and barbed rods respectively arranged on both sides of the intermediate rod. The upper end of the intermediate rod is pointed. One end of the horizontal rod is fixedly connected to the middle of the intermediate rod and is perpendicular to the support rod. One end of the barbed rod is fixedly connected to the intermediate rod and is located above the horizontal rod. The barbed rod is inclined downwards from the connection point with the intermediate rod, and the free end of the barbed rod is pointed.
[0006] The above-described multi-purpose linker for high-speed trains has multiple functions. The upper end of the middle bar is pointed, similar to a chisel, and can be used to remove ice from the pantograph or at the station. The horizontal bar is a support member and can be used to lift the pantograph. The barbed bars are distributed on the opposite side of the horizontal bar, forming a barbed structure, which facilitates the hooking and removal of foreign objects attached to the pantograph or at the station. It has the advantages of good foreign object removal effect and simple operation.
[0007] In some embodiments, a hammer head with an outer diameter larger than that of the horizontal rod is fixedly mounted on the free end of the horizontal rod. The hammer head, with an outer diameter larger than that of the horizontal rod, limits the lateral position of the pantograph when it is lifted, preventing displacement. Furthermore, the hammer head can be used as a hammer, effectively removing hard objects such as ice.
[0008] In some embodiments, a rubber grip is fitted to the lower end of the support rod. This rubber grip increases the feel and comfort of holding the rod.
[0009] In some embodiments, the support rod is composed of two or more rods connected together. A mounting sleeve is fixedly provided at the lower end of the upper rod, and the mounting sleeve has an internal threaded hole. A connector is fixedly provided at the upper end of the lower rod, and the connector has an external thread, which is threadedly connected to the mounting sleeve. The support rod is composed of multiple rods connected together, facilitating subsequent disassembly and storage.
[0010] In some embodiments, both the horizontal bar and the barb are threaded onto the intermediate bar. The horizontal bar and the barb employ a detachable, threaded connection. When the link is not in use, both the horizontal bar and the barb can be removed from the intermediate bar for easier storage.
[0011] In some embodiments, one end of the barb is rotatably connected to a central rod via a pivot. The central rod has a receiving groove for accommodating the barb, and a fastening nut is threaded onto the pivot. When the barb rotates around the pivot, it has a first state where it is concealed in the receiving groove and a second state where it is extended outwards. The fastening nut presses against the barb to lock it in either the first or second state. Since the barb hook is a barbed structure, storage and safety must be considered when not in use. Therefore, the barb hook is designed to be rotatable; when not in use, it can be folded onto the central rod for convenient and safe storage.
[0012] In some embodiments, a first toothed disc is provided at the upper end of the barb rod, surrounding the pivot shaft, and a second toothed disc is provided on the intermediate rod, surrounding the pivot shaft. The first and second toothed discs mesh and engage with each other. Adding the first and second toothed discs restricts the barb rod from rotating relative to the intermediate rod in a fixed state. Furthermore, this allows for adjustment of the barb rod's angle as needed, making it suitable for handling foreign objects in different locations, offering good flexibility and applicability.
[0013] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:
[0014] This application discloses a multi-purpose linker for high-speed trains, possessing multiple functions. The upper end of the middle bar is pointed, similar to a chisel, and can be used to remove ice from the pantograph or at train stations. The horizontal bar serves as a support and can be used to lift the pantograph. Barbed bars are distributed on opposite sides of the horizontal bar, forming a barbed structure, facilitating the hooking of foreign objects attached to the pantograph, jumper cables, and other high-voltage components or at train stations. It offers advantages such as effective removal of foreign objects and simple operation. Attached Figure Description

The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.
[0022] Example 1
[0023] See Figures 1 to 3 This application provides a multi-purpose linker for high-speed trains, including a support rod 1 and a working head 2 fixedly mounted on the support rod 1. The working head 2 includes a vertically arranged intermediate rod 21 and horizontal rods 22 and barbed rods 23 respectively arranged on both sides of the intermediate rod 21. The upper end of the intermediate rod 21 is pointed. One end of the horizontal rod 22 is fixedly connected to the middle of the intermediate rod 21, and the horizontal rod 22 is perpendicular to the support rod 1. One end of the barbed rod 23 is fixedly connected to the intermediate rod 21 and located above the horizontal rod 22. The barbed rod 23 is inclined downwards from the connection point with the intermediate rod 21, and the free end of the barbed rod 23 is pointed. The horizontal rods 22 and barbed rods 23 are both welded and fixed to the intermediate rod 21, and the lower end of the intermediate rod 21 is connected to the upper end of the support rod 1 by rivets.
[0024] This multi-purpose linker for high-speed trains has multiple functions. The upper end of the intermediate bar 21 is pointed, similar to a chisel, and can be used to remove ice from the pantograph or at the station. The horizontal bar 22 is a support component that can be used to lift the pantograph. The barbed bars 23 are distributed on the opposite side of the horizontal bar 22, with a barbed structure, to easily hook and remove foreign objects attached to the pantograph or at the station. It has the advantages of good foreign object removal effect and simple operation.
[0025] A hammer head 24 with an outer diameter larger than that of the horizontal rod 22 is fixedly installed at the free end of the horizontal rod 22. The hammer head 24, with its larger outer diameter than the horizontal rod 22, limits the lateral position of the pantograph when it is lifted, preventing displacement. Furthermore, the hammer head 24 can be used as a hammer, effectively removing hard objects such as ice.
[0026] A rubber grip 3 is installed at the lower end of the support rod 1. The rubber grip 3 can increase the feel and comfort of holding the rod.
[0027] The support rod 1 is composed of two or more rods 11 connected together. A mounting sleeve 12 is fixedly installed at the lower end of the upper rod 11, and the mounting sleeve 12 has an internal threaded hole 121. A connector 13 is fixedly installed at the upper end of the lower rod 11, and the connector 13 has an external thread, which is threadedly connected to the mounting sleeve 12. The support rod 1 is composed of multiple rods 11 connected together, facilitating subsequent disassembly and storage.
[0028] Example 2
[0029] To improve storage performance, this embodiment, based on embodiment one, has both the horizontal bar 22 and the barbed bar 23 threadedly connected to the intermediate bar 21. When not in use, both the horizontal bar 22 and the barbed bar 23 can be detached from the intermediate bar 21, making storage more convenient.
[0030] Example 3
[0031] See Figures 4 to 5 This illustrates another embodiment of the present application. In this embodiment, one end of the barb 23 is rotatably connected to the intermediate rod 21 via a pivot 4. The intermediate rod 21 is provided with a receiving groove 211 for accommodating the barb 23. A fastening nut 5 is also threaded onto the pivot 4. When the barb 23 rotates around the pivot 4, it has a first state of being hidden in the receiving groove 211 and a second state of being extended outwards. The fastening nut 5 presses against the barb 23 to lock the barb 23 in either the first or second state. Since the barb hook is a barb structure, storage and safety issues need to be considered when it is not in use. Therefore, the barb hook is designed to be rotatable. When not in use, the barb hook can be folded onto the intermediate rod 21, making storage convenient and safer.
[0032] The upper end of the barb 23 is provided with a first toothed disc 231 surrounding the rotating shaft 4, and the middle rod 21 is provided with a second toothed disc 212 surrounding the rotating shaft 4. The first toothed disc 231 and the second toothed disc 212 are engaged with each other. Adding the first toothed disc 231 and the second toothed disc 212 can restrict the rotation of the barb 23 relative to the middle rod 21 in a fixed state. Moreover, this allows the angle of the barb 23 to be adjusted as needed, making it applicable to foreign objects in different positions, with good flexibility and applicability.
