Description
Technical Field
The utility model relates to an expansion joint, especially a heavy load temperature expansion joint.
Background
The temperature expansion joint is designed according to the power failure caused by linear deformation (profile extrusion and abutting) generated when the sliding contact line is subjected to thermal expansion and contraction (profile contraction) under the condition that the sliding contact line works in different temperature environments. It is formed by two movable sections and the direct series connection of wiping line trunk line body, and its basic principle is: the static slide sheet and the dynamic slide sheet are overlapped and inserted to form a transition body which is matched with the slide contact line body, and the transition body can freely move linearly when the ambient temperature of the slide contact line changes. After the static sliding sheet and the dynamic sliding sheet are inserted in a stacked mode, no matter how the static sliding sheet and the dynamic sliding sheet extend or contract, the static sliding sheet and the dynamic sliding sheet can provide a straight transition plane for the electric brush of the collector, so that the faults that the expansion range is narrow, the electric brush of the collector is difficult to span, power failure is caused, the contact surface is small, spark is caused and the like caused by expansion of a joint in an early period are overcome.
