The invention provides a large low-temperature liquefied natural gas storage tank dome mounting device and method. The mounting device comprises a hoisting annular slide way assembly, an outer tooth rotating bearing, an inner and outer sliding direction track assembly, an annular slide way, a hoisting electric hoist and a splicing electric hoist. The outer tooth rotating bearing is installed above the storage tank, the inner and outer sliding direction rail assembly is connected with an outer bearing of the outer tooth rotating bearing, and the bottom of an inner bearing of the outer tooth rotating bearing is connected with the hoisting electric hoist. The hoisting annular slide way assembly is annularly arranged outside the outer tooth rotating bearing, the rotating motor provides power for rotation of the outer tooth rotating bearing, an outer bearing body of the outer tooth rotating bearing rotates around the axis of the outer bearing body, and the inner and outer sliding direction track assembly is arranged to move between the outer tooth rotating bearing and the hoisting annular slide way assembly in a reciprocating mode. The high-altitude splicing device can solve the problem of difficulty in high-altitude splicing of a large-mass dome part and the problem of splicing accuracy.
