Description

Direct-burried Steel Sleeve heat insulation type rolling guiding trestle

Affiliated technical field

The utility model relates to a kind of interior piping support device of Steel Sleeve, refers to a kind of interior pipe holder that buries the ground heat distribution pipeline especially.

Background technique

At present, the interior pipe travel(l)ing rest of direct-burried Steel Sleeve heat distribution pipeline generally all adopts the sliding-type guiding trestle, and mainly there is the defective of two aspects in this support: the first, and the steel sole plate of support directly contacts with the Steel Sleeve inwall, and sliding-frictional resistance is big.Actual measurement shows that the friction factor of the steel sole plate of support and Steel Sleeve inwall is greater than 0.3 (friction factor is generally 0.3 between steel and the steel), like this, when pipeline expands with heat and contract with cold, not only can produce bigger end thrust, and also can produce bigger noise and vibration sometimes fixed support; Second, the steel-tube seat of support directly contacts with outer wall of inner tube, formed the heat bridge of a heat transfer in making between pipe and the Steel Sleeve, so not only increased radiation loss, also cause Steel Sleeve part (with support base plate contact position) temperature too high, influenced the working life of Steel Sleeve outer wall anticorrosive coat.Above-mentioned defective will be to the safe operation and the working life of heat-net-pipeline all producing very adverse influence.

Summary of the invention

In order to overcome above-mentioned deficiency, the purpose of this utility model aims to provide a kind of direct-burried Steel Sleeve heat insulation type rolling guiding trestle, and this support can not only cut off the heat transfer heat bridge effectively, and friction factor is reduced.

The utility model will solve its technical problem: the partition heat transfer heat bridge and the friction factor problem of burying the travel(l)ing rest of pipe in the ground heat distribution pipeline.

The technological scheme that its technical problem that solves the utility model adopts is: this device has pipe clamp formula steel-tube seat, rolling leg and targeting part are formed, last pipe clamp and lower tube clip are by the clamping bolt folder on inner pipe, on, the inner edge of lower tube clip has the adiabatic pouring material of one deck, be lined with the flexible thermoinsulation material of one deck between adiabatic pouring material and the interior pipe, on, lower tube clip all has two above apertures, weight bearing area adopts the part to widen structure in the middle of the lower tube clip, this below, position is welded with a rolling leg, on the guide plate of substantially horizontal utilizes, the joint otic placode of lower tube clip extends, and the guide plate of Vertical direction is a curved steel plate in band strengthening rib top.

Described direct-burried Steel Sleeve heat insulation type rolling guiding trestle rolling leg is made up of support plate, roller bearing, roller and floor, and each rolling leg has a roller bearing at least, and each roller bearing is provided with two with upper roller, and roller links to each other with the underpart of support plate by roller bearing.

The guide plate both sides of described direct-burried Steel Sleeve heat insulation type rolling guiding trestle are welded with strengthening rib.This device serves as a contrast a kind of high-intensity adiabatic pouring material at the inner edge of pipe clamp formula steel-tube seat, and cutting off the heat transfer heat bridge, and with rolling leg replacement slip leg, the change sliding friction is rolling friction.

The beneficial effects of the utility model are: 1, cut off outer and inner tube heat transfer heat bridge effectively, reduced the radiation loss of pipeline, eliminated the too high and destruction to the outer wall anticorrosive coat that produces of invar sleeve pipe local temperature; 2, replace the slip leg with the rolling leg, friction factor reduces to 0.1 by 0.3, has reduced fricative end thrust and operating noise and vibration, has eliminated the hidden danger that vibration brings; 3, simple in structure, materials are saved, and make easily.
