Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail welding technology, and more specifically, to a ballast-type rail mobile welding ramp pad. Background Technology
[0002] With the increasing operating time and freight volume of existing railway lines in my country, rail wear is becoming increasingly serious. To ensure the safe, stable, and reliable operation of railways, rail welding is a crucial step in laying seamless railway tracks and an important guarantee for the safety of train operation.
[0003] Currently, during on-site mobile welding operations, the welding machine cannot be directly positioned for welding due to a conflict between its size and the structure of the pre-embedded iron base of the ballasted track. It is necessary to raise the rails on both sides of the weld joint to prevent interference between the welding machine and the pre-embedded iron base structure when clamped. Raising the rails on both sides of the weld joint creates a slope, known as a slope support. Once the welding machine climbs the slope, the welding operation can be completed smoothly.
[0004] There are two main methods for supporting rails on slopes. First, on-site personnel use wooden planks, round steel bars, or steel plates of a certain height to support the rails. This method is somewhat arbitrary, with inconsistent sizes and unreliable structural strength. It makes it difficult to achieve lateral and longitudinal positioning and fixation of the rails while they are being raised, posing safety hazards and increasing the risk of the welding machine derailing or overturning. Second, existing technology uses sleeper bolts as a fixing reference to achieve lateral and longitudinal locking of the support blocks in the rail groove. This technology is only suitable for track work on ballast tracks with anchor bolts, and its size is set based on the anchor bolts on the concrete sleeper rail groove. It is not suitable for ballast track rail moving and welding operations on slopes using pre-embedded iron seat fasteners.
[0005] Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

With the rails facing away from each other, the rail 45 is placed on the top surface of the upper body 1. The first limiting inclined surface 20 and the second limiting inclined surface 23 are then positioned opposite each other.
