Abstract
The utility model relates to a combined rolling support saddle of an overhead heat distribution pipeline, which is characterized in that: the combined rolling support saddle is mainly formed by a support saddle and a saddle-type protection seat, the support saddle consists of an epsilon-type base and rollers, the epsilon-type base is connected with the two rollers through a pin shaft, the saddle-type protection seat is formed by a soleplate and two parallel straight plates which are vertically fixed onto the soleplate, the upper end surface of the straight plate presents in an arc shape, and the saddle-type protection seat is arranged on the rollers of the support saddle. The combined rolling support saddle has the beneficial effects that: besides the effects of supporting weight, limiting (or guiding) displacement, controlling vibration (shaking), reducing the push force and the like, the combined rolling support saddle has the advantages of simple structure, large carrying force, strong adaptability, long service life, low price and the like. The friction coefficient is low: mu is less than or equal to 0.1; self-lubrication performance is good: the friction pair is free from oil or lubricant, so the maintenance workload is reduced; the adaptability is strong: the support saddle can work in different environments, and the performance is stable and reliable; and the combined rolling support saddle resists the abrasion: under normal situation, the service life can reach more than 15 years.
Description
Technical field
The utility model belongs to the outdoor overcast of heating power transmission pipeline network, relates in particular to a kind of combined roller support of built on stilts heat distribution pipeline.
Background technique
When heat distribution pipeline laid in the built on stilts mode of outdoor employing, pipeline needed stent support, and common way is to bury column underground, connects bearing and integrant overcast in the column upper fixed.The overcast form is multiple, is mainly used in the pipeline and the equipment of generation thermal walking in service.Have that bearing capacity is big, supporting ﹠ stablizing, characteristics such as reliable, be widely used in oil, chemical plant installations and other need reduce the place of displacement stress.Combined pillar commonly used is applicable to and supports large-scale pipeline and equipment, has solved the problem that ordinary stent support and load can't satisfy actual demand effectively.Applicable scope: displacement range 0-60mm, working load 21000-2500000N, pipeline nominal size model 175-4000mm; Environmental Conditions temperature range-20 ℃～200 ℃.The structural type of combined pillar is divided into single 2 groups of combinations, single 3 groups of combinations, single 4 groups or double 4 groups of combinations, single 5 groups or single and double 5 groups of combinations, double 6 groups of combinations, double 8 groups of combinations and double 10 groups of totally 9 kinds of basic structure forms.The stand apparatus of support adopts flat friction pair usually, selects steel-steel pair, polyfluortetraethylene plate or mirror finished stainless steel material for use.The bearing of above-mentioned support is the planar slide friction, and friction factor is bigger, influences the normal displacement amount of pipeline. ?
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of combined roller support of built on stilts heat distribution pipeline is provided, and adopts rolling type to support, and the coefficient of reducing friction has that bearing capacity is big, adaptability strong, the advantage of long service life.
The utility model for achieving the above object; by the following technical solutions: a kind of combined roller support of built on stilts heat distribution pipeline; it is characterized in that: mainly constitute by bearing and saddle protection seat; described bearing is made of the base and the roller of mountain font; the base of described mountain font and two rollers are by the bearing pin pin joint; described saddle protection seat by base plate and with it two blocks of straight parallel plates of vertical fixing constitute, described straight plate upper-end surface is circular-arc, described saddle protection places on the roller of bearing.
Beneficial effect: stand apparatus except that supported weight, restriction (or guiding) displacement, control shake (rolling) moving, reduce thrust etc. acts on, and have simple in structure, bearing capacity is big, adaptability is strong, long service life, advantage such as cheap.Friction factor is low: μ≤0.1; Self lubricity is good: need not oiling or oiling agent between friction pair, reduce maintenance workload; Adaptability is strong: be useful in work under the various ambient conditions, and stable and reliable for performance; Wear-resistant: as under normal circumstances, to reach working life more than 15 years.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure; a kind of combined roller support of built on stilts heat distribution pipeline; mainly constitute by bearing 1 and saddle protection seat 2; described bearing is made of the base 3 and the roller 4 of mountain font; the base of described mountain font and two rollers are by bearing pin 5 pin joints; described saddle protection seat by base plate 2-1 and with it two straight parallel plate 2-2 of vertical fixing constitute, described straight plate upper-end surface is circular-arc, described saddle protection places on the roller of bearing.
During use, bearing is fixed on the connecting plate on yard piping 6 column tops, saddle protection seat is placed on the roller of bearing, the heat supply pipeline frame is on the arc surface of saddle protection seat.When heating tube expands with heat and contract with cold when mobile, then drive roller and form rolling friction.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
