Abstract
The utility model relates to a movable support for supporting a pipeline or a device, which comprises an upper bottom plate and a lower bottom plate, wherein a plurality of polytetrafluorethylene plates are arranged between the upper bottom plate and the lower bottom plate, and the upper bottom plate is connected with a ribbed plate and a vertical plate which support the pipeline. The utility model is characterized in that a stainless steel plate with a mirror surface is arranged on the upper surface of the lower bottom plate, and the upper surface of each polytetrafluorethylene plate is fixedly connected with the lower surface of the upper bottom plate to form a friction pair between the lower surface of each polytetrafluorethylene plate and the stainless steel plate with a mirror surface. The utility model can fully use the friction reducing characteristic of polytetrafluorethylene materials and has the advantages of reasonable structure, safe and reliable use and high efficiency.
Description
The utility model relates to a kind of pipeline fittings of heat distribution pipeline, particularly a kind of movable bearing support that supports pipeline or equipment.
The present movable bearing support of employed support pipeline or equipment in above-mentioned technical field mainly contains two major types:
One class is rolling or the sliding support that carbon steel is made, and the nominal friction factor of roller support is 0.1, but because factor affecting such as foozle and Environmental Conditions corrosion, its actual friction factor is much larger than design load.And be that its nominal friction factor of sliding support that friction pair is made is 0.3 with the carbon steel, friction factor will be bigger in actual the use.
Another kind of for being lined with the sliding support of polyfluortetraethylene plate.Have directly be encased inside polyfluortetraethylene plate and unfixing, often lost efficacy because of pad slips away.Though what have has a fixed structure,, polyfluortetraethylene plate and the excessive shearing strength that causes shearing stress to surpass teflon of steel plate linear expansion difference cause inefficacy because of causing to destroy.Also having a kind of is the hole of circular teflon gasket being put into the spacing fixed plate of having reserved the clearance for expansion, but this mode still can not be given full play to the antifriction characteristic of polytetrafluoroethylmaterial material, and its economic benefit is still not ideal enough.
The purpose of this utility model is exactly the problem that exists in the prior art in order to solve, a kind of antifriction characteristic that can make full use of polytetrafluoroethylmaterial material is provided, rational in infrastructure, safe and reliable, the clipping interlayer teflon of high efficiency low friction mechanism sliding support.
Technical solution of the present utility model:
The clipping interlayer teflon of a kind of low friction mechanism sliding support, it includes upper and lower base plate, be provided with the polylith polyfluortetraethylene plate between the upper and lower base plate, upper plate is connected with floor and the riser that is used to support pipeline, it is characterized in that on the upper surface of lower shoe, being provided with the mirror finished stainless steel plate, and the upper surface of each polyfluortetraethylene plate and the lower surface of upper plate are affixed, make to form friction pair between each polyfluortetraethylene plate lower surface and the mirror finished stainless steel plate.
The utility model compared with prior art, and is of the present utility model reasonable in design, simple in structure, the reliability height.Adopt the mode of sandwich-type polyfluortetraethylene plate multidigit mechanical grip to install upward, both solved the fixedly problem of difficulty, can give full play to the antifriction potentiality of teflon again, make to the utlity model has extremely low dry friction coefficient (μ≤0.04).The utility model is used to have the heat distribution pipeline of thermal walking, can reduce friction thrust more than 86%, thereby can greatly reduce the pipe-networks engineering cost, and especially to high aerial pipeline, its effect is more obvious.The utility model can be widely used in the support of all heat distribution pipelines of thermal walking, is applicable to that also the needs of thermal walking or mechanical displacement lower the support of any equipment of surface friction drag.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the A-A sectional schematic diagram of Fig. 1;
Fig. 4 is that the amplification perspective view is cutd open by slot type retaining member of the present utility model and polyfluortetraethylene plate office thereof.
As Fig. 1-3, the utility model includes upper and lower base plate 1,2, be provided with polylith polyfluortetraethylene plate 3 between the upper and lower base plate 1,2, upper plate 1 is connected with floor 5 and the riser 6 that is used to support pipeline 4, characteristics of the present utility model are to be provided with mirror finished stainless steel plate 7 on the upper surface of lower shoe 2, and the lower surface of the upper surface of each polyfluortetraethylene plate 3 and upper plate 1 is affixed, makes to form friction pair between each polyfluortetraethylene plate 3 lower surface and the mirror finished stainless steel plate 7.
In order to guarantee reliable connection the between upper plate 1 lower surface and each polyfluortetraethylene plate 3 upper surface, can be provided with the slot type retaining member 8 of a plurality of border seals at upper plate 1 lower surface, as shown in Figure 4, the upper end of each retaining member 8 and upper plate 1 lower surface are connected, there is flange 9 in its one week of lower end, make and form a circumferential groove 10 between them, correspondingly each piece polyfluortetraethylene plate 3 is a step plate, its upper board 11 is big, and lower panel 12 is little, and is provided with metal twine interlayer 13 in the upper board 11, they are an integral body, work to improve join strength, the outer rim of upper board 11 just in time matches with the circumferential groove 10 of corresponding clip gripping member 8, and their coincide to connect and fuse.The upper board 11 of each polyfluortetraethylene plate 3 just organically fuses by each retaining member 8 with the lower surface of upper plate 1 like this, and its underpart plate 12 just and between the mirror finished stainless steel plate 7 forms friction pair.
The utility model is fixed in the mode of polylith sandwich-type polyfluortetraethylene plate 3 with mechanical grip on the upper plate 1 of support securely.The linear expansion amount of polyfluortetraethylene plate 3 is controlled in the gap that mechanical slot type retaining member 8 provided.Because the Stainless Steel Cloth interlayer 13 in each polyfluortetraethylene plate 3 plays the effect of gaining in strength, disperse load, so can improve polyfluortetraethylene plate 3 reliability of fixation on support upper plate 2.The following of each interlayer polyfluortetraethylene plate 3 is mirror finished stainless steel plate 7, and they are fixed on the lower shoe 2 of support.2 of lower shoes are fixed with the embedded part on buttress or the support.Specific structure is that polyfluortetraethylene plate 3 slides on mirror finished stainless steel plate 7 when having guaranteed thermal walking, and the friction factor of this moment is smaller or equal to 0.04, so can give full play to the antifriction characteristic of teflon, so frictional force minimum.
