Abstract
The invention relates to a connection tube load considered vertical container skirt. The vertical container skirt comprises a base plate which is connected with a skirt platform. Reinforcing ribs are arranged between the skirt platform and the base plate. A group of connection tubes is connected onto the skirt platform, two pairs of inspection holes are formed in the skirt platform, and axes of the two pairs of inspection holes intersect by 40 degrees to 55 degrees. Vector addition is performed on the load of each connection tube in four working conditions of equipment, and five groups of numerical values of tri-axial forces and bi-axial torque are calculated respectively; the five groups of numerical values are subjected to vector addition with the seismic load, wind load and gravitational load respectively, and numerical values of the tri-axial forces and the bi-axial torque in each working condition are calculated; the maximum of the tri-axial forces and the bi-axial torque in all the working conditions is found and introduced into the skirt to be applied to the connection tube load considered vertical container skirt.
Description
technical field:
the present invention relates to a kind of method of calculating of adapter load being considered to vertical vessel skirt load.
background technology:
in recent years, along with the going from strength to strength, develop of China's chemical industry, the use of pressure vessels for the chemical industry was more and more, and skirt, from the vertical vessel of supporting type, is used service conditions also to become increasingly complex.The support pattern of vertical vessel mainly contains leg formula bearing support, hanging support supporting, prop support and skirt supporting etc., for the equipment important, quality is heavier, conventionally adopts skirt supporting.
general skirt is when the vertical vessel equipment of supporting carries out skirt LOAD FOR, owing to considering that vertical vessel is generally higher, affected by wind load, earthquake load larger, if adapter load is also very large, the cost that can increase vertical equipment increases device security risk simultaneously.In whole chemical process system, generally, when system, by the flexibility (as increased suspension and support etc.) of pipeline between increase equipment, reduce the adapter load of equipment, in conventional design, according to standard, do not need to consider to take over the impact of load on skirt.But be subject to space constraint, between two equipment, distance is too near, in the time of cannot reducing pipeline flexible by measures such as increase suspension and supports, between two equipment, certainly will there is larger adapter load, now just must consider to take over the impact of load on equipment skirt, adapter load is executed in the calculating of considering skirt and gone, guarantee the safety supporting of equipment.
summary of the invention:
the object of the present invention is to provide a kind of method of calculating of adapter load being considered to vertical vessel skirt load.
the object of the present invention is achieved like this:
a kind of vertical vessel skirt of considering to take over load, its composition comprises: base plate, described base plate joint skirt platform, between described skirt platform and described base plate, there is strengthening rib, on described skirt platform, connect one group of adapter, described skirt platform has 2 pairs of sightholes, 2 pairs of described sighthole Axis Cross 40-55 degree;
first, take the most basic theory of mechanics as basis, under four kinds of operating modes of equipment, each takes over load, carries out respectively vector addition, calculates respectively three-dimensional power and two to moment totally five groups of numerical value;
secondly, these five groups of numerical value are carried out to vector addition with earthquake load, wind load, gravity loading respectively, calculate under every kind of operating mode, three-dimensional power and two numerical value to moment;
finally find out three-dimensional power and two maxims to moment under all operating modes, again maxim is brought into JB/T 4710---in 2005 < < steel tower type container > > skirt computing formula, carry out conventionally calculation, according to the result of calculation of vertical equipment skirt thickness and reinforcement structure, make skirt.
the vertical vessel skirt of load is taken in described consideration, and described operating mode comprises: design conditions, operation operating mode, the operating mode that continues, accidental operating mode.
the vertical vessel skirt of load is taken in described consideration, and described adapter load comprises: three-dimensional power and three-dimensional moment.
beneficial effect:
1. the present invention be take the most basic theory of mechanics as basis, easy to understand, convenience of calculation, safe and reasonable.
the specific embodiment:
embodiment 1:
a kind of vertical vessel skirt of considering to take over load, its composition comprises: base plate, described base plate joint skirt platform, between described skirt platform and described base plate, there is strengthening rib, on described skirt platform, connect one group of adapter, described skirt platform has 2 pairs of sightholes, 2 pairs of described sighthole Axis Cross 40-55 degree;
first, take the most basic theory of mechanics as basis, under four kinds of operating modes of equipment, each takes over load, carries out respectively vector addition, calculates respectively three-dimensional power and two to moment totally five groups of numerical value;
secondly, these five groups of numerical value are carried out to vector addition with earthquake load, wind load, gravity loading respectively, calculate under every kind of operating mode, three-dimensional power and two numerical value to moment;
finally find out three-dimensional power and two maxims to moment under all operating modes, again maxim is brought into JB/T 4710---in 2005 < < steel tower type container > > skirt computing formula, carry out conventionally calculation, according to the result of calculation of vertical equipment skirt thickness and reinforcement structure, make skirt.
embodiment 2:
the vertical vessel skirt of taking over load according to the consideration described in embodiment 1, described operating mode comprises: design conditions, operation operating mode, the operating mode that continues, accidental operating mode.
embodiment 3:
according to embodiment 1, consider to take over the vertical vessel skirt of load, described adapter load comprises: three-dimensional power and three-dimensional moment.
embodiment 4:
according to the consideration described in embodiment 1, take over the vertical vessel skirt of load, take and operate operating mode as example, in conjunction with subordinate list, the present invention is further illustrated with concrete case:
subordinate list-certain vertical equipment given tensile load computation chart
in conjunction with subordinate list, take operate operating mode, 3 adapters are example, by taking over load, consider in the calculating of vertical vessel skirt load.
