Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

As shown in fig. 1, a support for a high-temperature pipeline according to a preferred embodiment of the present invention includes a pipeline clamp 1, a bottom plate 2 and a support frame 3, wherein the pipeline clamp 1 is used for clamping and fixing a pipeline 6; the pipeline clamp 1 is slidably mounted on the bottom plate 2, for example, a slide rail can be arranged on the bottom plate 2, a slide block matched with the slide rail is arranged on the bottom surface of the pipeline clamp 1, and the pipeline clamp 1 slides relative to the bottom plate 2 through the sliding of the slide block relative to the slide rail; in a working state, the pipeline 6 generates a thermal displacement after being heated, the pipeline clamp 1 moves along with the pipeline, and the bottom plate 2 is welded and fixed and cannot move, so that the pipeline clamp 1 slides on the bottom plate 2, the bottom plate 2 provides support for the pipeline clamp 1 on one hand, and the friction force can be reduced on the other hand; the bottom plate 2 is fixed the top of support frame 3, and the bottom of support frame 3 is placed on floor 5, the surface of pipeline clamp 1 is provided with color development coating 4, when pipeline clamp 1's outer wall temperature exceeded the settlement temperature, color development coating 4 shows and sets for the colour to the temperature of this pipeline 6 of warning staff is high temperature, avoids scalding the staff.

According to the invention, through the arranged color development coating layer 4, when the temperature of the outer wall of the pipeline clamp 1 exceeds the set temperature, the set color can be displayed, so that the temperature can be judged by naked eyes, whether the bracket can touch or not is judged, and the high temperature is avoided from scalding the maintainers, thereby facilitating the maintainers to overhaul the pipeline 6 and avoiding causing potential safety hazards.
