Abstract
The utility model discloses a direct-buried steam pipeline rolling guide support bracket, which is mainly composed of a support seat. The utility model is characterized in that the support seat is provided with at least two support legs, and the support legs are fixed with tilt wheels. The utility model has the advantage of novel structure and replaces the surface contact method of traditional products with a point-line contact method, the friction coefficient of the utility model is reduced to only 0.1. Meanwhile, the utility model reduces the thrust generated from friction and reduces the noise and vibration in actual motion, so the utility model eliminates the safety hazard caused by the vibration and accomplishes the effects of support bracket miniaturization, low weld working capacity and safer operation.
Description
The utility model relates to a kind of bearing device, particularly relates to a kind of support of buried pipe.
At present, the movable bearing support that adopts in the direct-buried steam pipeline engineering is the slide-and-guide bearing.Its working method be base-plate with Steel Sleeve between contact sliding type for face.The subject matter that it exists is: frictional force and vibration noise are big, exist the unsafe hidden danger of heating network operation.
Now with 250 ℃ of steam operating temperatures, every meter insulation pipe weight 60kg, the steam insulation pipe of length of pipe section 50m is an example, sets forth the problem that adopts sliding support to exist; 1. the actual measurement friction factor between sliding support base plate and Steel Sleeve is 0.4; 2. frictional force reaches 1.2t; 3. when pipeline expands with heat and contract with cold, can produce bigger noise between base-plate and the Steel Sleeve, sometimes also with oscillation phenomenon.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, the direct-buried steam pipeline rolling guiding trestle that contacts with the Steel Sleeve dotted line.
Technical solutions of the utility model are, a kind of direct-buried steam pipeline rolling guiding trestle mainly is made up of bearing, and its characteristics are: bearing is provided with at least two legs, is fixed with roller on the leg.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the utility model novel structure, be skillfully constructed, contact the face way of contact that has replaced traditional product with dotted line, reduced friction factor widely, making it only is 0.1, reduced fricative thrust simultaneously, made it only be original 1/4th.And reduced noise and the vibration in the actual motion, thereby also eliminated the hidden danger that vibration can bring, reached and make the support miniaturization, reduced the welding job amount, moved safer reliable effect, the tool promotional value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, the lower end of bearing 10 is provided with two legs 20, is fixed with roller 30 by bolt 40 and nut 50 in the leg 20.
