Abstract
The utility model discloses a power pipeline anti-whip device, which comprises at least two U-shaped draw bars. The two ends of the U-shaped draw bar are arranged on a base which is fixedly connected with an installation base through at least four ground screws. The U-shaped draw bar is made of the profiled bar with high intensity and good plasticity. The section size of the U-shaped draw bar is determined by computing the material intensity and the whip load when the power pipeline breaks. The intensity of the U-shaped draw bar is less than the connection intensity between the U-shaped draw bar 1 and the base 2 and between the base 2 and the installation base 3. The two ends of the U-shaped draw bar are arranged on the base which is fixedly connected with the installation base. When the power pipeline is damaged, the U-shaped draw bar absorbs whip energy through plastic extension and deformation and transfers the stress to the installation base through the base, base bolts and the like. Consequently, the secondary damage of the whip of the pipeline on adjacent establishment and personnel is avoided. The utility model has simple structure and is safe and reliable.
Description
Technical field
The utility model relates to the anti-rejection device of a kind of power conduit, the effective anti-rejection device of extraction duct whipping energy when specially referring to power conduit damaged accident taking place.
Background technique
Power conduit in running, the normally High Temperature High Pressure carbonated drink medium of carrying in the pipeline.When damaged accident took place power conduit, pipeline very easily caused secondary disaster because of the interior pressure effect generation whipping of high-energy fluid.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, can not damage pedestal and the anti-rejection device of power conduit of basis, safety is installed.
In order to achieve the above object, the technical solution of the utility model is: the anti-rejection device of a kind of power conduit, comprise U type pull bar, and the two ends of described U type pull bar are installed on the pedestal, and pedestal is connected with the installation basic fixed.
Described pedestal is fixedlyed connected by at least 4 stone bolt with the installation basis.
Described U type pull bar has two at least.
Described U type pull bar by intensity higher and plasticity preferably shaped steel make, whipping load when damaged takes place according to Material Strength and power conduit and calculates and determine in its sectional dimension.
The body intensity of described U type pull bar is less than the join strength between U type pull bar and pedestal, pedestal and the installation basis.
After adopting said structure, the two ends of U type pull bar are installed on the pedestal, pedestal is connected with the installation basic fixed, when damaged accident takes place in power conduit, pipeline whipping load action is on U type pull bar, by U type pull bar generation plastic elongation distortion extraction duct whipping energy, prevent that the power conduit whipping from causing secondary disaster.The pedestal of assurance device, installation basis etc. are not damaged only U type pull bar generation plastic elongation distortion simultaneously.Apparatus structure is simple, safe and reliable.
Description of drawings
The example that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the anti-rejection apparatus structure schematic representation of power conduit of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, 2, the anti-rejection device of a kind of power conduit comprises U type pull bar 1, and the two ends of described U type pull bar 1 are installed on the pedestal 2, and pedestal 2 is fixedlyed connected with installation basis 3.
As Fig. 1; shown in 2; described pedestal 2 with basis 3 be installed fixedly connected by at least 4 stone bolt 4; guarantee join strength and connective stability between pedestal 2 and the installation basis 3; make its assembling join strength greater than the join strength between U type pull bar 1 and the pedestal 2; guarantee when damaged accident takes place power conduit; pipeline at first acts on the U type pull bar 1 because of the whipping load that the interior pressure effect of high-energy fluid is produced; U type pull bar 1 absorbs the whipping energy by the plastic elongation distortion; prevent pedestal 2 and basis 3 be installed damage, and will be stressed by pedestal → foundation bolt etc. be delivered to install basic.
As shown in Figure 2, the effective whipping energy of extraction duct of U type pull bar 1 when making power conduit that damaged accident take place, described U type pull bar 1 has two at least, guarantees pipeline whipping displacement restriction within the scope that design allows.
As shown in Figure 1, 2, in order to ensure with pipeline whipping displacement restriction in the scope that design allows, prevent that the pipeline whipping from causing secondary disaster, described U type pull bar 1 by intensity higher and plasticity preferably shaped steel make, whipping load when damaged takes place according to Material Strength and power conduit and calculates and determine in its sectional dimension.
As shown in Figure 1, 2, the intensity of described U type pull bar 1 prevents pedestal 2 and basis 3 destructions is installed less than the join strength between U type pull bar 1 and pedestal 2, pedestal 2 and the installation basis 3.
The utility model is sleeved on U type pull bar 1 on the power conduit in use, and it is fixedlyed connected with pedestal 2, guarantees to leave certain clearance between power conduit and the U type pull bar 1.U type pull bar of the present utility model two ends are installed on the pedestal, pedestal is connected with the installation basic fixed, when damaged accident took place power conduit, U type pull bar 1 was by plastic elongation distortion extraction duct whipping energy, and will be stressed by pedestal → foundation bolt etc. be delivered to install basic.Thereby prevented that the pipeline whipping from causing secondary harm to contiguous facility and personnel.
