Abstract
The invention belongs to the technical field of a high-temperature pipeline supporting pipe frame and particularly relates to a bidirectional heat-displacement pipeline bracket. The bidirectional heat-displacement pipeline bracket is characterized by comprising an upper supporting base and a lower supporting base, wherein a convex spherical surface is arranged on the top part of the lower supporting base; a concave spherical surface matched with the convex spherical surface is arranged on the bottom part of the upper supporting base; an upper rolling plate, a middle rolling plate and a bottom plate are sequentially arranged on the bottom part of the lower supporting base from top to bottom; an inclined iron is arranged between the upper rolling plate and the lower supporting base; rolling body sets are arranged between the upper rolling plate and the middle rolling plate, as well as between the middle rolling plate and the bottom plate respectively. The bidirectional heat-displacement pipe bracket is simple and reasonable in structure, and convenient to manufacture and mount, and is applied to a high-temperature pipeline with large pipe frame load and relatively large displacement in two horizontal directions; friction coefficients of a pipeline bracket and a supporting piece are reduced, and the thrust of the pipe frame to a supporting beam is reduced.
Description
Technical field
The present invention relates to a kind of two-way thermal walking support of pipelines, belong to high temperature pipe and support pipe support technical field.
Background technique
In petrochemical plant in the past, unit scale is little, pipeline straight length is short, pipeline axially and radial displacement less, load is little, the displacement of pipeline in horizontal both direction can solve by increasing polyfluortetraethylene plate under pipe support, , along with unit scale maximizes, such as just there is pipeline specification 78 inches with reaction zone on the dehydrogenating propane device built in domestic driving at present, Horizontal displacement east-west direction is 228mm North and South direction 135mm, load 18 tons, common pipe support cannot solve the displacement of both direction, pipeline can only be solved by steel to steel friction, in pipeline heats up slowly temperature-rise period, pipe support must bear the thrust of about 5 tons, when device stops, because the too large pipeline of frictional force cannot return to initial design state.Be easy to cause the expansion joint damaged on this pipeline.Cause pipeline to ftracture time serious, cause fire, bring invisible economic loss to device.
Summary of the invention
The technical problem to be solved in the present invention is: provide one to be convenient to install, the displacement that can solve high temperature pipe level two direction supports pipe support, and it is large that this pipe support can meet load, the requirement that displacement is large, reduce friction factor, reduce the two-way thermal walking support of pipelines of the thrust of frame supported beam.
Two-way thermal walking support of pipelines of the present invention, it is characterized in that: comprise upper bracket and undersetting, undersetting top arranges convex spherical, the concave ball surfaces coordinated with convex spherical is set bottom upper bracket, rolling plate, middle rolling plate and base plate is set gradually from top to bottom bottom undersetting, between upper rolling plate and undersetting, wedge is set, between upper rolling plate and middle rolling plate, between middle rolling plate and base plate, roll body group is all set.
Pipeline to be supported by pipe support or seat supports at upper bracket on the surface; Upper bracket is contacted by spherical with undersetting, avoids the load of pipeline because producing when pipe support is subjected to displacement.Undersetting is connected by wedge when installing, wedge totally 4 groups, adjustment setting height(from bottom), ensures that the lower supporting plate of undersetting contacts well with upper rolling plate.Upper rolling plate is placed in roll body group, then is placed on middle rolling plate, and place lower roll body group under middle rolling plate, be then placed on substrate, base plate adjusts levelness by jackscrew.
Described upper bracket comprises upper backup pad and is positioned at the upper supporting column bottom upper backup pad, arranges concave ball surfaces bottom upper supporting column, and undersetting comprises lower supporting plate and is positioned at the lower supporting rod at lower supporting plate top, and lower supporting rod top arranges convex spherical.Pipeline to be supported by pipe support or seat supports at upper backup pad on the surface.
Between upper backup pad and upper supporting column, stiffening rib is set, lower stiffening rib is set between lower supporting plate and lower supporting rod.Increase the intensity of upper supporting column.
Described roll body group comprises retainer, and retainer arranges roller, and the arranged direction of the upper and lower two groups of rollers of middle rolling plate is mutually vertical.
Described upper and lower two roll body groups are set to 2 respectively, and often group is made up of the roller of 6 φ 60mm length 380mm.
The invention has the beneficial effects as follows:
Simple and reasonable, fabrication and installation are convenient, are used in pipe support load large, the high temperature pipe that the displacement of horizontal both direction is larger.Reduce the friction factor of line holder and supporting element, reduce pipe support to the thrust of support beam.

In figure: 1, upper backup pad 2, upper stiffening rib 3, upper supporting column 4, convex spherical 5, lower supporting rod 6, lower stiffening rib 7, lower supporting plate 8, upper rolling plate 9, roller 10, retainer 11, middle rolling plate 12, base plate 13, wedge.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, two-way thermal walking support of pipelines of the present invention, comprise upper bracket and undersetting, undersetting top arranges convex spherical 4, the concave ball surfaces coordinated with convex spherical 4 is set bottom upper bracket, set gradually rolling plate 8, middle rolling plate 11 and base plate 12 bottom undersetting from top to bottom, between upper rolling plate 8 and undersetting, wedge 13 is set, between upper rolling plate 8 and middle rolling plate 11, between middle rolling plate 11 and base plate 12, roll body group is all set.The upper supporting column 3 that upper bracket comprises upper backup pad 1 and is positioned at bottom upper backup pad 1, arranges concave ball surfaces bottom upper supporting column 3, and undersetting comprises lower supporting plate 7 and is positioned at the lower supporting rod 5 at lower supporting plate 7 top, and lower supporting rod 5 top arranges convex spherical 4.Stiffening rib 2 is set between upper backup pad 1 and upper supporting column 3, lower stiffening rib 6 is set between lower supporting plate 7 and lower supporting rod 5.Roll body group comprises retainer 10, retainer 10 is arranged roller 9, and the arranged direction of middle rolling plate about 11 two groups of rollers is mutually vertical.Upper and lower two roll body groups are set to 2 respectively, and often group is made up of the roller of 6 φ 60mm length 380mm.
Pipeline to be supported by pipe support or seat supports at upper backup pad 1 on the surface, when being subjected to displacement in temperature-rise period, this two-way thermal walking support of pipelines passes through the orthogonal roll body group of each 2 groups of rotating directions up and down, reach pipeline displacement request, the friction factor of line holder and supporting element is reduced to 0.001 by 0.3, greatly reduces the thrust of support during pipeline displacement.
