Description

Technical Field

[0001] This utility model relates to the field of rail tools technology, specifically to a rail breaking tool. Background Technology

[0002] Adhesive-bonded insulated joints play a crucial role in railway systems, ensuring the normal operation of insulated track circuits and turnouts on seamless tracks. However, the replacement process faces numerous challenges when the adhesive insulation of railway lines fails.

[0003] There are two main traditional dismantling methods, both with significant drawbacks. First, the method involves manual, alternating blows with sledgehammers and axes, requiring multiple people and dozens or even hundreds of blows, taking nearly an hour to complete. Given the extremely limited time available during railway maintenance "windows," this is not only inefficient but also extremely labor-intensive. Second, the method uses oxygen and acetylene heating, requiring heavy heating equipment, specialized operators, and subsequent dismantling with sledgehammers, axes, and crowbars. Both methods are time-consuming, reducing maintenance efficiency, and pose a risk of damaging the rails, potentially affecting their future performance. Furthermore, the operation involves open flames and heavy impacts, posing significant safety hazards and increasing the risk of personal injury to operators. Utility Model Content

[0004] Therefore, this utility model provides a rail breaking tool to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] According to a first aspect of the present invention, a rail breaking tool includes a guide device, a rail impactor, and impact pins. One end of the guide device is detachably connected to the rail impactor, and the other end of the guide device is connected with two impact pins at intervals. The cross-sectional shape of each impact pin is a right trapezoid.

[0007] Furthermore, the guiding device includes a first guide member, a second guide member, and a rotating shaft. The first guide member and the second guide member are rotatably connected by the rotating shaft. One end of the first guide member and one end of the second guide member are both connected to the rail impactor. The other end of the first guide member and the other end of the second guide member are respectively connected to an impact pin.

[0008] Furthermore, the first guide member includes a first connecting block, a first rotating block, and a first guide block. The upper end of the first connecting block is provided with a first rotating block, the lower end of the first connecting block is provided with a first guide block, and an impact pin is provided on the first guide block. The first rotating block is rotatably connected to the upper end of the second guide member.

[0009] Furthermore, the second guide member includes a second connecting block, a second rotating block, and a second guide block. The upper end of the second connecting block is provided with a second rotating block, and the lower end of the second connecting block is provided with a second guide block. An impact pin is provided on the second guide block, and the second rotating block and the first rotating block are rotatably connected by a rotating shaft.

[0010] Furthermore, the first guide also includes a first handle, which is provided on the upper surface of the first connecting block.

[0011] Furthermore, the second guide also includes a second handle, which is provided on the upper surface of the second connecting block.
