Abstract
The utility model relates to a planar heat-insulating sliding support for a large-caliber straight buried pipe. The planar heat-insulating sliding support comprises an upper pipe clamp and a lower pipe clamp, wherein the upper pipe clamp and the lower pipe clamp are both semicircular. The upper pipe clamp and the lower pipe clamp are connected to form an annular structure. The inner arc surface of the upper pipe clamp and the inner arc surface of the lower pipe clamp are respectively provided with a hard heat insulating layer. One surface of one hard heat insulating layer is connected with the inner arc surface of the upper pipe clamp, and one surface of the other hard heat insulating layer is connected with the inner arc surface of the lower pipe clamp. The other surface of each hard heat insulating layer is provided with a soft heat insulating layer which makes contact with a core pipe. The outer arc surface of the lower pipe clamp is symmetrically provided with a first supporting plate and a second supporting plate. The bottom of the first supporting plate and the bottom of the second supporting plate are provided with a bottom plate. A sliding platform is arranged under the bottom plate and is arranged on the inner wall of an outer sleeve. The planar heat-insulating sliding support is capable of separating a heat bridge, improving efficiency, reducing vibration between the pipe clamps and the core pipe, ensuring normal sliding of the core pipe when the core pipe is in large heat displacement and also ensuring normal sliding of the core pipe when the core pipe is in lateral displacement in the process of self compensation, and being applicable to the large-caliber straight buried pipe.
Description
Technical field
The utility model relates to the heat insulation sliding support of plane for a kind of heavy caliber direct buried pipe, the heat insulation sliding support of plane for the direct buried pipe of especially a kind of >=DN600.
Background technique
At present, the transmission of steam source adopts directly buried type steam line conventionally, and in pipeline, the mobile meeting of high-temperature steam makes steam line that displacement axially and radially occur, and therefore in the pipeline of long distance, needs to carry out supporting pipeline with heat-insulating bracket.In " steel sleeve steel " directly buried type steam line, conventionally apply three kinds of supports, be respectively guiding trestle, sliding support and fixed support, in having elbow two segment pipes of extraction duct dilatancy ability, in order to make the freely dilatancy of extraction duct of elbow, conventionally use sliding support.Sliding support only limits working steel tube along pipeline vertical diameter to downward displacement, and do not limit working steel tube, does not protect outside in steel pipe and moves freely along other direction, is conducive to like this dispersion of stress in the absorption of distortion and pipeline.
The direct buried pipe of existing >=DN600 adopts high temperature resistant asbestos packing as thermal-protective coating with heat insulation sliding support is normal, need to be wound around multilayer outward at core pipe and just can reach insulation requirement, and its heatproof is lower, conventionally only have 200 ℃ of left and right, and easily aging, come off, the installation of thermal-protective coating is also inconvenient, wastes time and energy; Between heat-insulating bracket and core pipe, easily produce heat bridge phenomenon and cause heat to run off in a large number, cause energy waste; In addition, often adopt to roll to contact in heat insulation sliding support bottom with outer tube wall, because outer sleeve is spiral welded steel pipe, steel pipe inner wall has weld seam, easily causes heat insulation sliding support with weld seam rotation or stuck by weld seam, affects support and normally slides.Described DN600 represents the nominal diameter of pipe, and the external diameter of DN600 steel pipe is between 610～630mm.

The technological scheme providing according to the utility model, the heat insulation sliding support of plane for a kind of heavy caliber direct buried pipe, comprises pipe clamp and lower tube clip, it is characterized in that: described upper pipe clamp and lower tube clip are semicircle, upper pipe clamp and lower tube clip connect and compose a loop configuration; On the intrados of described upper pipe clamp and lower tube clip, be equipped with hard heat-insulating layer, the one side of hard heat-insulating layer is connected with the intrados of upper pipe clamp and lower tube clip, and soft thermal-protective coating is set on the another side of hard heat-insulating layer, and soft thermal-protective coating contacts with core pipe; On the outer arced surface of lower tube clip, be arranged with the first dunnage and the second dunnage; The bottom of the first dunnage and the second dunnage is provided with base plate; Below base plate, be provided with sliding platform, sliding platform is arranged on outer sleeve inner wall.
Outside in described the first dunnage and the second dunnage is provided with floor, and described floor is connected with the outer arced surface of lower tube clip.
Described sliding platform comprises slide plate, is provided with channel-section steel below slide plate, is provided with stiffening plate between channel-section steel.
The utlity model has following advantage: adopt the design of circular arc hard heat-insulating layer, cut off heat bridge, improve efficiency of transmission; Increase soft thermal-protective coating, pipe clamp and core duct ligation have been closed tightr, reduced between pipe clamp and core pipe and vibrate, improved heat resistance; The design of employing pipe clamp type, easy for installation; Select reinforced bracket and the basal sliding platform of double inverted T-shaped structure, can guarantee when core pipe has larger thermal walking normally to slide, while having Side movement in the time of can also guaranteeing nature compensation, the normal slip of core pipe; Each parts are all strengthened, and have guaranteed the normal operation of heavy caliber direct-burried steel pipe.
