Description
Technical Field
[0001] The utility model relates to the technical field of railway transportation, in particular to a welding assembly for track embedded parts. Background Art
[0002] With the development of the times, my country's railway construction has entered a high-speed era. Railway transportation is a land-based transportation method in which locomotives pull trains along two parallel tracks. However, railway transportation in a broad sense includes non-steel wheel transportation methods such as magnetic levitation trains, cable cars, and ropeways, also known as rail transportation.
[0003] Existing technology: CN213857693U is a track embedded parts welding assembly for railway transportation. By setting a moving device, the fixed block is equipped with a pulley and connected to the splint. Driven by the splint, it is clamped to the track so that the equipment is installed above the track. When welding at different positions, it is only necessary to push the device to move on the track. There is no need to disassemble and transport the device to weld embedded parts at different positions. When the equipment is finished using, the screw rod is rotated to loosen the fixed block, and the entire device can be disassembled and transported. It is very convenient and quick to use, greatly reducing the time cost caused by the need to transport the device when welding at different places, and improving work efficiency.
[0004] At present, quality control is more difficult and there are more risk factors. There are still a series of problems such as deviation of civil engineering structure, displacement of embedded parts, wrong position of embedded parts when placing, loose fixation of embedded parts, displacement during concrete pouring, and loose contact between subsequent embedded parts and structure. In general, the quality control of welding of rails for newly built seamless railway lines mainly involves welding of rail bases, welding of long rails, transportation and storage, welding on site, and laying, releasing and locking of seamless lines. All of these operations need to be strictly controlled. In addition, the expansion bolts of embedded parts after welding are too small from the edge of the structure, the exposed length of the embedded anchor bolts does not meet the requirements, and the welding between embedded plates is not firm, which reduces the practicality of the welded parts. Therefore, a welding assembly for track embedded parts is needed to improve the above problems. Utility Model Content
