TECHNICAL FIELD
[0001] The utility model relates to the technical field of rail laying and carrying, in particular to a rail clamp for rail laying and carrying. BACKGROUND
[0002] Rail is the main component of railway track, used to guide the movement of locomotive and vehicle, and distribute and transfer the concentrated load of wheel to the subgrade or bridge and tunnel structure. According to the steel type, it is divided into carbon rail, alloy rail and heat treated rail. Carbon rail is made of carbon steel, with low cost but relatively low strength and toughness. Alloy rail is made of carbon steel with alloy elements such as manganese, chromium and nickel, to improve the strength and toughness of the rail. Heat treated rail improves the microstructure of the rail through heat treatment process to improve its comprehensive performance. According to the single weight, it is divided into heavy rail and light rail. Heavy rail has larger single weight, suitable for high-speed and heavy-load railway. Light rail has smaller single weight, suitable for low-speed and light-load railway or special line. In the specific operation of rail laying and carrying, the rail clamp also plays an important role. For example, after pushing the rail to the predetermined position, the rail clamp can be used to clamp and stabilize the rail to ensure that it meets the design requirements.
[0003] The traditional rail clamp for rail laying and carrying is mainly used to clamp and fix the rail at a specific position during the laying and carrying process, so as to be lifted, moved or installed. The rail clamp is usually used with lifting equipment, which lifts the rail to the designated position through the lifting force of the lifting equipment. The rail clamp and the lifting equipment work together. The rail clamp is responsible for fixing the rail, while the lifting equipment is responsible for providing the lifting force. However, this method is mainly suitable for machine lifting, and the construction personnel cannot directly lift it. Not only can the rail not be accurately installed and placed in place, but also it cannot be installed and laid in limited space. Therefore, a rail clamp for rail laying and carrying is proposed.
