Abstract

The invention discloses steel rail welding equipment which comprises a heating head and a controller. The heating head is arranged at a weld joint between two steel rails to be welded, the heating head is spiral magnetic heating equipment, the upper end of the heating head is connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are connected with the controller. The heating head is used for directionally and uniformly heating through spiral magnetic induction, so that the temperature of the steel rails is uniformly increased, and the welding quality is improved. The controller can accurately control the time and temperature, random variable-control temperature regulation at 500 DEG C-2500 DEG C is realized, and the occurrence of defects such as thermal cracking of central slag bubbles and the like is reduced. The equipment is light, easy to carry and suitable for railway field operation. Combustible gases such as oxygen and acetylene are not used in the equipment, so that potential safety hazards such as fire disasters and explosion are avoided. The steel rail welding equipment is simple in structure, convenient to operate and worthy of popularization.

Description

Technical field [0001] The present invention relates to the technical findings of railway rail welding equipment, and more particularly to a spiral magnetically heated steel soldering device. Background technique [0002] Rail welding technology is to connect different rail segments, eliminate the operation of the rails, and more and more seamless railways in the development of modern railways, seamless rails can reduce the vibration and impact of trains, or extend train wheel parts. Life, rail welding technology is a key factor in achieving seamless railway construction. About the welding method of the rails mainly include flash welding, air pressure welding, aluminum hot welding and arc welding. Among them, fixed flash welding is mainly used in plant welding or base welding, mobile flash welding and mobile air pressure welding for cell rail festival on-site welding, aluminum heat welding and arc welding are commonly used for on-site locking welding, overhauling and road welding...
