DETAILED DESCRIPTION
[0025] 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.
[0026] Example 1
[0027] like Figure 1 As shown, a vibration-damping and heat-insulating pipe rack includes a base plate 10, a support 20, a pipe clamp 30, a heat-insulating assembly 40, an inverted U-shaped clamp 50 and a vibration-damping assembly 60. The support 20 is centrally arranged at the top of the base plate 10, the pipe clamp 30 is installed at the top of the support 20, the pipe clamp 30 clamps the pipe, the heat-insulating assembly 40 is arranged between the pipe and the pipe clamp 30, the inverted U-shaped clamp 50 is arranged directly above the pipe clamp 30 and presses the pipe clamp 30, and the left and right sides of the inverted U-shaped clamp 50 are respectively connected to the base plate 10 through the vibration-damping assembly 60. The heat insulation of the pipe is achieved by the setting of the heat-insulating assembly 40, and the radial vibration of the pipe is buffered by the setting of the vibration-damping assembly 60, so that the vibration and noise reduction of the pipe are achieved, and the thermal stress and stress generated by vibration inside the pipe can be eliminated and released. Specifically, the base plate 10 is fixed on the foundation; the support 20 provides the supporting force of the pipe.
[0028] like Figure 1 and Figure 2As shown, the thermal insulation component 40 includes an aerogel plate 41 and a compression plate 42. The aerogel plate 41 is arranged on the outer wall of the pipe, and the compression plate 42 is arranged on the inner wall of the pipe clamp 30. The opposite surfaces of the aerogel plate 41 and the compression plate 42 are in contact with each other. Specifically, the aerogel plate 41 is made of silicon dioxide and has a semicircular cross-section; the compression plate 42 is made of fiber and has a semicircular cross-section. Since the aerogel plate 41 and the compression plate 42 have a certain elasticity, the thermal insulation component 40 also has a certain vibration reduction effect, thereby improving the shock reduction effect.
[0029] like Figure 1 As shown, the vibration reduction assembly 60 includes a sleeve 61, a screw 62, a disc spring group 63 and an adjusting nut 64. The sleeve 61 is vertically arranged and connected to the inverted U-shaped clip 50. The bottom end of the screw 62 is connected to the base plate 10. The screw 62 passes through the sleeve 61 and is loosely matched with the sleeve 61. The disc spring group 63 is sleeved on the top of the screw 62 and contacts the top of the sleeve 61. The adjusting nut 64 is threadedly installed on the top of the screw 62 and contacts the top of the disc spring group 63. When the pipeline drives the inverted U-shaped clip 50 to vibrate due to radial vibration, the damping effect of the disc spring group 63 buffers the vibration of the inverted U-shaped clip 50, thereby achieving vibration reduction and noise reduction of the pipeline. In addition, the threaded connection between the adjusting nut 64 and the screw 62 makes the vibration reduction assembly 60 adjustable. Specifically, the disc spring group 63 is composed of a plurality of disc spring sheets stacked together.
[0030] like Figure 4 and Figure 5 As shown, the pipe clamp 30 includes an upper hoop body 31, a lower hoop body 32 and a locking group 33.

Through the setting of the locking group 33, the clamping of the pipe by the upper hoop body 31 and the lower hoop body 32 is flexible and fixed, which prevents the pipe from being subjected to excessive clamping force, and also enables the heat insulation assembly 40 to have a certain vibration reduction function. Specifically, the cross-sections of the upper hoop body 31 and the lower hoop body 32 are both semicircular.
[0031] like Figure 5 As shown, the locking group 33 includes a locking bolt 331, a locking nut 332 and a disc spring 333. The top of the locking bolt 331 passes through the upper hoop body 31 and the lower hoop body 32 in sequence and is threadedly connected with the locking nut 332. The disc spring 333 is sleeved on the locking bolt 331 and arranged between the locking nut 332 and the upper hoop body 31. The arrangement of the disc spring 333 enables the upper hoop body 31 and the lower hoop body 32 to flexibly fix the pipeline.
[0032] like Figure 1 and Figure 2As shown, the vibration-damping and heat-insulating pipe rack further includes an upper sliding assembly 70 and a lower sliding assembly 80, wherein the upper sliding assembly 70 is arranged between the pipe clamp 30 and the inverted U-shaped clamp 50, and the lower sliding assembly 80 is arranged between the base plate 10 and the support 20. By arranging the upper sliding assembly 70 and the lower sliding assembly 80, the support 20 and the base plate 10 as well as the pipe clamp 30 and the inverted U-shaped clamp 50 can be slightly moved relative to each other, and the friction force is sliding friction, so as to ensure the release of pipeline stress.
[0033] like Figure 2 and Figure 3 As shown, the upper sliding assembly 70 includes a polytetrafluoroethylene plate 71 and a mirror stainless steel plate 72. The polytetrafluoroethylene plate 71 is arranged on the inner wall of the inverted U-shaped clamp 50, and the mirror stainless steel plate 72 is arranged on the outer wall of the pipe clamp 30. The opposite surfaces of the polytetrafluoroethylene plate 71 and the mirror stainless steel plate 72 are slidably matched. Specifically, the front and rear ends of the polytetrafluoroethylene plate 71 protrude from the inverted U-shaped clamp 50, and the front and rear ends of the mirror stainless steel plate 72 protrude from the polytetrafluoroethylene plate 71, thereby ensuring the stability of sliding.
[0034] like Figure 1 and Figure 2 As shown, the lower sliding assembly 80 includes an upper polytetrafluoroethylene plate 81 and a lower polytetrafluoroethylene plate 82. The upper polytetrafluoroethylene plate 81 is arranged at the bottom end of the support 20, and the lower polytetrafluoroethylene plate 82 is arranged at the top end of the base plate 10. The relative surfaces of the upper polytetrafluoroethylene plate 81 and the lower polytetrafluoroethylene plate 82 are slidably matched.
