Abstract

The utility model relates to a buried pipeline rolling heat-insulation bracket, which comprises outer casing pipes, pipe clamps, drum-wheel brackets, drum wheels and heat-insulation tiles. The cross section of the heat-insulation tile presents an arc shape; a plurality of heat-insulation tiles are surrounded to form a section of circular pipe; a plurality of connected pipe clamps are sleeved outside the heat-insulation tiles; the cross section of the pipe clamp presents an arc shape; the plurality of pipe clamps are connected to form a tubular shaped body; three or more drum-wheel brackets are fixedly arranged on the pipe clamps; the top end of each drum-wheel bracket is provided with the drum wheel in a rotating way; the outer casing pipe is sleeved outside the pipe clamp; the clearance exists between the drum wheel and the inner wall surface of the outer casing pipe. The buried pipeline rolling heat-insulation bracket can ensure expansion and contraction of the barrel of the stem pipeline, reduce friction force, be installed in any angle, solve direction problem during installing of the directly-buried pipe for the construction unit, and ensure the even stress in the outer casing pipe for the barrel.

Description

The buried pipe heat insulation support that rolls

Technical field

The utility model relates to a kind of directly buried type prefabricated thermal insulation steam line parts, especially a kind of buried pipe heat insulation support that rolls.

Background technique

The heat insulation type rolling support is a directly buried type prefabricated thermal insulation steam line significant components, and the reliability of its effect of heat insulation, work will be directly connected to operation heat waste, environmental protection and the safe operation of buried steam line.At present, the suitable buried pipe heat insulation support that rolls does not but appear.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of frictional force little, can guarantee steam line core pipe expand with heat and contract with cold, guarantee core pipe even stressed buried pipe heat insulation support that rolls in outer sleeve.

The technological scheme that provides according to the utility model, the described buried pipe heat insulation support that rolls, comprise outer sleeve, pipe clamp, the drum support, drum and heat insulation tile fragment, heat insulation tile fragment section is circular-arc, some heat insulation tile fragments surround one section pipe shape, be connected to the some pipe clamps that join at heat insulation tile fragment overcoat, it is circular-arc that the section of described pipe clamp also is, some pipe clamps formation tubular body that joins, at the drum support that is set with on the pipe clamp more than three or three, be provided with drum at each equal rotating turret of drum cantilever tip portion, outside pipe clamp, be socketed with outer sleeve, have the gap between described drum and the outer sleeve inner wall face.

Described drum support is distributed on the circumference of pipe clamp formation.The outer end of all drums is positioned on the same circumference.The gap that has 10～15mm between described drum and the outer sleeve inner wall face.

The utility model can guarantee expanding with heat and contract with cold of steam line core pipe, has reduced frictional force, can arbitrarily angledly install, and has solved the directionality problem of unit in charge of construction when direct buried pipe is installed, and guarantees core pipe evenly stressed in outer sleeve.

Description of drawings

Fig. 1 is an overall structure schematic representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: this buried pipe heat insulation support that rolls, comprise outer sleeve 1, pipe clamp 2, drum support 3, drum 4 and heat insulation tile fragment 5, heat insulation tile fragment 5 sections are circular-arc, some heat insulation tile fragments 5 surround one section pipe shape, outside heat insulation tile fragment 5, be socketed with the some pipe clamps that join 2, it is circular-arc that the section of described pipe clamp 2 also is, some pipe clamps 2 formation tubular body that joins, at the drum support 3 that is set with on the pipe clamp 2 more than three or three, be provided with drum 4 at the equal rotating turret of each drum support 3 tip portion, outside pipe clamp 2, be socketed with outer sleeve 1, have the gap between described drum 4 and outer sleeve 1 internal face.

Described drum support 3 is distributed on the circumference of pipe clamp 2 formation.The outer end of all drums 4 is positioned on the same circumference.The gap that has 10～15mm between described drum 4 and outer sleeve 1 internal face.

The buried pipe of the present utility model heat insulation support guide function that rolls is good, be used in buried steam line,, can guarantee that steam line core pipe 6 expands with heat and contract with cold as the guiding trestle behind the corrugated expansion joint, distortion is vertically moved, and guarantees corrugated expansion joint safe operation and working life.Owing to adopted drum 4, reduced friction factor greatly, thereby reduced frictional force, another big characteristics are, four direction all is equipped with drum support 3 and drum 4, can arbitrarily angledly install, solved the directionality problem of unit in charge of construction when direct buried pipe is installed, guarantee core pipe 6 evenly stressed in outer sleeve 1.
