Abstract
The utility model discloses a dedicated diamond draw bar for a compound expansion joint. The dedicated diamond draw bar for the compound expansion joint comprises panels and is characterized in that the panels are movably connected. According to the dedicated diamond draw bar for the compound expansion joint, disclosed by the utility model, a diamond draw bar is formed together by the panels, round bars and spherical gaskets, the diamond draw bar can move movably, an expansion joint cannot be pressed broken by self load when the panels are in work together with the round bars and the spherical gaskets, and the uniform deformation of a corrugated pipe or a ring belt of the compound expansion joint can be ensured.
Description
Technical field
The utility model relates to a kind of expansion joint, and particularly a kind of compound expansion saves special-purpose pull bar.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.Expansion joint also is slip joint traditionally; Or corrugated expansion joint; Be that effective dilatation in order to the elastic element that utilizes corrugated expansion joint absorbs pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element.Can be to axially, laterally and the absorption of angular displacement, be used for adding thermal walking, mechanical displacement absorbed oscillation, reduce noise etc. in pipeline, equipment and system.The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that on container, adopts has various ways, with regard to the shape of ripple, uses the most extensively with the U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint that on pipeline, adopts has universal, pressure balance type, hinge type and universal joint formula etc. again with regard to structure compensation.Bellows expansion joint is a kind of expansion joint of processing with metal bellows.It can be flexible along axial direction, also allows a small amount of crooked.The expansion joint pull bar is the part of expansion joint fender bracket, and traditional expansion joint fender bracket is a fixed structure, when the expansion joint deadweight is too heavy, damages the expansion joint fender bracket by pressure easily.Also have a kind of compound expansion joint, be connected by a plurality of expansion joints and form.This compound expansion joint because the degree of shrinking can not be that safety is consistent, causes whole device stress different and be out of shape between each expansion joint when shrinking, and perhaps is out of shape because of deadweight, even damages.
The model utility content
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, provides a kind of compound expansion of flexible connection to save special-purpose rhombus pull bar.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of compound expansion saves special-purpose rhombus pull bar, comprises 4 panels, it is characterized in that flexibly connecting between panel and the panel.
As the further improved technological scheme of the utility model, also comprise round bar, be connected through round bar between panel and the panel.
As the further improved technological scheme of the utility model, also comprise spherical pad, the spherical pad pad is between panel and round bar.
In the utility model; Panel, round bar and spherical pad have constituted the rhombus pull bar together, and this rhombus pull bar can be movable, when panel is worked with round bar and spherical pad; Can guarantee that expansion joint is not damaged by pressure by deadweight, and guarantee compound expansion joint bellows or astragal homogeneous deformation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model in expansion joint.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Embodiment 1
Referring to Fig. 1; This compound expansion saves special-purpose rhombus pull bar and comprises panel 1, round bar 2 and spherical pad 3, and panel 1 has 4, and round bar 2 has 4; Flexibly connect through round bar 2 between panel 1 and the panel 1; Spherical pad 3 pads are between panel 1 and round bar 2, and when panel 1 was stretched, spherical pad 3 can be adjusted the position automatically to be made stressed even.When expansion joint is stressed, can stretch or compress between the panel 1, guarantee that expansion joint is not damaged by pressure by deadweight, and guarantee compound expansion joint bellows or astragal homogeneous deformation.
Claims (3)
1. a compound expansion saves special-purpose rhombus pull bar, comprises 4 panels, it is characterized in that flexibly connecting between panel and the panel.
2. compound expansion according to claim 1 saves special-purpose rhombus pull bar, it is characterized in that also comprising round bar, is connected through round bar between panel and the panel.
3. compound expansion according to claim 2 saves special-purpose rhombus pull bar, it is characterized in that also comprising spherical pad, and the spherical pad pad is between panel and round bar.
