Insulating pipe bracket for large-diameter low-temperature pipeline

An insulating pipe bracket for a large-diameter low-temperature pipeline comprises a vertically-arranged support and an insulating block, the upper portion of the support is a square frame, and the insulating block is fixed in the square frame through a limiting check block. A circle of locking steel ring is welded in the circumferential direction of the large-diameter low-temperature pipe, locking blocks are welded to the two sides of the locking steel ring, grooves matched with the locking steel ring and the locking blocks in shape are formed in the insulation block, and the locking steel ring and the locking blocks are embedded into the grooves of the insulation block. One side of the limiting stop block is welded to the frame, the other side of the limiting stop block is connected with the insulation block through a gasket, and the insulation block is clamped in the square frame through the gasket. The pipeline fixing device has the beneficial effects that movement of the end of a pipeline in six directio
