DETAILED DESCRIPTION

[0031] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

It also includes a soft insulation layer 50, a hard insulation block 60, a support pipe 70 and a limit assembly 80. The upper pipe clamp 10 and the lower pipe clamp 20 form a circle, and the soft insulation layer 50 is clamped on the outer wall of the pipeline. The base 40 is a center opening at the top. The hollow structure is a hard insulation block 60 arranged in the cavity of the base 40. The bottom end of the support tube 70 is supported at the top center of the hard insulation block 60, and its top passes through the lower pipe clamp 20 and the soft insulation layer 50 in sequence, and contacts the outer wall of the pipe. The limit assembly 80 includes an upper comb tooth block 81 and a lower comb tooth block 82. The upper comb tooth block 81 is respectively installed at the left and right ends of the upper pipe clamp 10, and the lower comb tooth block 82 is respectively installed at the left and right ends of the lower pipe clamp 20. The upper comb tooth block 81 and the lower comb tooth block 82 are engaged with each other. Through the arrangement of the soft insulation layer 50 and the hard insulation block 60, two cold and heat insulation lines are formed. At the same time, the close fit between the soft insulation layer 50 and the pipe avoids the appearance of gaps, thereby improving the cold and heat insulation effects. Combined with the arrangement of the limit assembly 80, the pipe is prevented from axial movement, thereby further improving the cold and heat insulation effects and ensuring stability. Since the soft insulation layer 50 is flexible, the support pipe 70 provides support for the pipeline, preventing the soft insulation layer 50 from collapsing under pressure, thereby ensuring the cold-keeping and heat-insulating effects.

[0034] Specifically, the upper pipe clamp 10 and the lower pipe clamp 20 are both semicircular; the soft insulation layer 50 is made of composite material; the hard insulation block 60 is made of polyisocyanurate (PIR) or castable; the support pipe 70 is designed to be cylindrical for easy processing and installation; the dual-temperature pipe support has an operating temperature of -200 to +1200°C.

The disc spring 34 is arranged between the fastening sleeve 31 and the first nut 33. The gasket 35 is arranged between the first nut 33 and the disc spring 34. The bolt sleeve 36 is arranged between the relative fastening sleeves 31. Through the arrangement of the fastening assembly 30, the fastening adaptation of the upper pipe clamp 10 and the lower pipe clamp 20 is realized, ensuring that the pipeline is always clamped, thereby ensuring that the soft insulation layer 50 is always in close contact with the pipeline, improving the cold and heat insulation effect, practicality and reliability.

By setting the sliding friction pair 120, the friction coefficient between the base 40 and the H-shaped steel 110 is reduced, and the friction resistance when the pipeline generates thermal displacement is reduced, thereby reducing the pipeline stress.

[0040] Example 3

[0041] like Figure 6 As shown, in this embodiment, a guide block 130 is additionally provided on the basis of the embodiment 2. The guide blocks 130 are respectively arranged at the left and right ends of the polytetrafluoroethylene substrate 123 to guide the sliding of the dual-temperature pipe support.

The box body 171 is a hollow structure and is installed on the top of the H-shaped steel 110. The sleeve 172 is embedded in the top center of the box body 171. The top of the lifting column 173 is connected to the bottom center of the base 40, and its bottom passes through The sliding sleeve 172 extends into the box 171, the bidirectional screw rod 174 is rotatably installed in the box 171, the slider 175 is composed of two pieces, which are respectively threadedly sleeved on both ends of the bidirectional screw rod 174, the bottom end of the slider 175 is slidably connected to the inner bottom wall of the box 171, and its top end is hinged to the bottom end of the connecting rod 176, the top end of the connecting rod 176 is hinged to the bottom side wall of the lifting column 173, and the right end of the bidirectional screw rod 174 extends outside the box 171 and is connected to the hand wheel 177. Through the setting of the lifting box 170, the support height of the dual-temperature pipe support can be adjusted, so as to adapt to the support of pipelines of different heights.

[0049] When adjusting the lifting, the hand wheel 177 is rotated, thereby synchronously driving the bidirectional screw rod 174 to rotate. The rotation of the bidirectional screw rod 174 is converted into the relative linear motion of the two sliders 175. The relative linear motion of the two sliders 175 drives the lifting column 173 to rise and fall through the connecting rod 176, thereby driving the base 40 to rise and fall.
