Abstract

The utility model relates to a novel sliding supporting seat for supporting heat distribution pipelines, comprising a lower fixing plate fixed on a base seat and an upper sliding plate arranged on the lower fixing plate for supporting pipelines. The two plate surfaces contact each other to slide, wherein, one surface is coated with a flexible graphite composite interlayer plate, and the other plate which corresponds to the surface is a stainless steel mirror plate; the flexible graphite composite interlayer plate is compounded by a metal thin plate and a flexible graphite paper plate coated on the surface of the metal thin plate. The utility model uses graphite plate materials to reduce friction coefficient, enhance corrosion resistant and aging-resistant properties and prolong the service life of the supporting seat.

Description

Novel sliding support

The utility model relates to the heat distribution pipeline engineering, is meant the sliding support that the support tube road is used especially.

In industries such as chemical industry, thermoelectricity, the support of heat distribution pipeline, at present, the friction slip that adopt general steel plate to make are paid more, so that pipeline when rising-heat contracting-cold, produces the slide relative displacement with supporting base, to guarantee the safety of pipeline and pedestal, and the steel plate friction slip is paid very easily corrosion, increased friction factor, in addition the rust stubbornly refuse and can slide, easily cause the accident, sometimes then take to increase measures such as base size, from and increased construction investment.Chinese patent literature ZL95218942 discloses a kind of " filled polytetrafluoroethylene sliding support ", it is that multidigit embeds the compound plate of teflon on the pedestal fixed plate, thereby alleviated corrosion, reduced friction factor, but because teflon is an organic plastics, easily aging, influenced working life.

The purpose of this utility model is to provide a kind of novel flexible graphite composite sandwich plate sliding support, makes it corrosion-resistant, anti-aging, lubricity is good, and friction factor is little, and construction investment is economized, long service life.

Hold within the utility model, novel sliding support, be one by be fixed on the pedestal (9) bottom plate (8) with its on be connected with the even part that the upper sliding plate (2) of carriage (1) constitutes, bottom plate contacts with the upper sliding plate face, but the slide relative displacement is characterized in that, the upper sliding plate bottom surface, perhaps the bottom plate end face is covered with Expanded graphite composite sandwich plate (3), and corresponding with it another plate is a stainless steel mirror board.

As a preferred version of the present utility model, be the bottom surface that the Expanded graphite composite sandwich plate is spread on upper sliding plate, establish back-up ring (6) around the upper sliding plate, bottom plate (8) end face middle part is boss (7).

As another preferred version of the present utility model, be to make a plurality of grooves (10), and embed Expanded graphite composite sandwich plate plate (3 ') at the bottom plate end face.

Such scheme, because of two relative plate faces of bearing, one is flexible graphite sheet material, one is the mirror finished stainless steel plate, high anticorrosive because corrosion-resistant chemical stability, wear-resisting, the high-lubricity of graphite material make this sliding support friction factor little, long service life.

The present invention is the improvement to prior art, it has a bottom plate (8) that is fixed on the pedestal (9), a upper sliding plate (2), carriage (1) in trustship road is fixedly connected on it, bottom plate contacts with the upper sliding plate face, but the slide relative displacement, the surface of one of them plate is covered with the Expanded graphite composite sandwich plate, and another plate of phase couple is a stainless steel mirror board with it.

Accompanying drawing 1, it is a preferred embodiment of the present utility model, it is bottom surface apposition Expanded graphite composite sandwich plate (3) at upper sliding plate (2), can adopt bonding method or frame inlaying process to be fixed on the bottom surface, present embodiment has adopted ring washer (6) fixing, and ring washer (6) also plays protective actions such as dustproof sand, sleet simultaneously, and with bottom plate make the middle part epirelief boss (7), its end face adopts corrosion resistant plate, and surface Machining becomes minute surface, to reduce friction; Fig. 3 is the A-A sectional view of present embodiment, and the upper sliding plate area is greater than bottom plate boss area, and periphery is stopped the slide displacement amount; Fig. 2 enlarged view, show Expanded graphite composite sandwich plate (3), by being the sandwich plate that Expanded graphite cardboard (4) and sheetmetal or orifice plate (5) constitute, its only rare layer of metal plate, both sides coat the Expanded graphite cardboard, present embodiment adopts two layers of sheet metal, the steel plate punching, three layers of Expanded graphite cardboard, adopt tackiness agent pressurization embedding method to make, this composite sandwich plate has improved stiffness, toughness and the intensity of simple graphite cardboard, then bring into play the high wear resistance of graphite material, lubricity, corrosion-resistant and chemical stability.The foregoing description, also can be with the apposition of Expanded graphite composite sandwich plate in the bottom plate end face, and stainless steel mirror board is adopted in the upper sliding plate bottom surface, bottom plate boss end face is processed into the groove (not shown), only stay four edges of projection, adopt tackiness agent to press and embed in the groove, and make the graphite cake end face a little more than four edges.

Accompanying drawing 4, be another embodiment of the present utility model, be to process a plurality of grooves (10) in the bottom plate end face, all embed in each groove and the Expanded graphite composite sandwich plate plate (3 ') of groove with shape, the plate end face should be not less than bottom plate boss apical side height, preferably slightly high, corresponding upper sliding plate bottom surface still adopts corrosion resistant plate to be processed into minute surface, preferably is provided with ring washer (6).Fig. 5 is a present embodiment B-B sectional view, and bottom plate adopts multidigit to embed polylith Expanded graphite composite sandwich plate plate and embeds monoblock graphite composite sandwich plate, and approximately uniform using effect is arranged.
