Abstract
The utility model discloses a novel flexible flange structure of cut open, including a body, be equipped with the steel pipe connecting hole in the axle center direction of body, be equipped with a plurality of bolt holes in the circumferencial direction of body, the circumference wall department of terminal surface is equipped with the inclined plane under the body. The utility model discloses simple structure, reasonable in design can effectively reduce the bending deformation of ring flange through the perk power that reduces the ring flange and receives, reduces the bolt atress between the ring flange, has alleviated the deformation of bolt to a certain extent, has reduced the cost of maintaining, has practiced thrift a large amount of manpower and materials.
Description
Technical field：
The utility model is related to a kind of novel groove flexible flange structures.
Background technology：
It is the eighties in last century, many national when developing UHV transmission line in the world, start steel tube profile application
It has arrived in iron tower structure, has occurred using steel pipe as the steel tube tower of tower body main material.In Japan, the supertension line and high tower of 1000kV
Middle almost all has used steel tube tower, they are very thorough to the designing technique research of steel tube tower.Foreign Experience, the country exist
It 500kV Double Loop Steel Towers and is returned with tower four and has also used steel tube profile in steel tower, embodied its superperformance and benefit.Have
Reduce tower body wind pressure, in the case where area of section is equal, the radius of gyration of pipe is made a call to 20% or so and improved than angle steel to be finished
The feature of structure carrying energy.But the steel pipe flange used in present steel tube tower, under the influence of receiving the loads such as aeolian vibration for a long time,
Ring flange flexural deformation is easy tod produce, there is security risk；Bolt between ring flange is easily deformed, is loosened, need into
Row is frequent to be replaced and safeguards, is wasted a large amount of human and material resources, be can not meet the demand of producer.
Invention content：
The utility model is to provide a kind of novel groove flexible flange to solve the above-mentioned problems of the prior art
Structure.
Technical solution used by the utility model has：A kind of novel groove flexible flange structure, including an ontology, at this
The axis direction of body is equipped with fastener for connection hole, and several bolts hole, the circumference in ontology lower face are equipped in the circumferencial direction of ontology
Inclined-plane is equipped at wall.
Further, the angle of inclination between the inclined-plane and ontology lower face is 5~10 °.
Further, welding section is equipped at the upper port in the fastener for connection hole.
Further, the bolt hole is at least provided with 16.
The utility model has the advantages that：
The utility model is simple in structure, reasonable design, can stick up power suffered by ring flange by reducing, effectively reduce ring flange
Flexural deformation, reduce ring flange between it is bolt strained, alleviate the deformation of bolt to a certain extent, reduce maintenance at
This, has saved a large amount of manpower and materials.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model application structure figure.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, a kind of novel groove flexible flange structure of the utility model, including an ontology 2, in the axis of ontology 2
Heart direction is equipped with fastener for connection hole 20, and several bolts hole 22, the circumference in 2 lower face of ontology are equipped in the circumferencial direction of ontology 2
Inclined-plane 21 is equipped at wall.Angle of inclination between 2 lower face of inclined-plane 21 and ontology is 5~10 °.
Welding section 23 is equipped at the upper port in fastener for connection hole 20.
Bolt hole 22 in the utility model is at least provided with 16.
In use, being fixedly connected by fillet weld between ontology 2 and steel pipe, two ontologies 2 are bolted to connection, this
Inclined-plane 21 on body 2 can reduce flanged plate prying force position to the distance of bolt, to reduce the pulling force on bolt.Inclined-plane 21
Power can be stuck up suffered by ontology 2 by reducing, effectively reduce the flexural deformation of ring flange, reduce it is bolt strained between ring flange, one
The deformation for determining to alleviate bolt in degree, reduces the cost of maintenance, has saved a large amount of manpower and materials.
By establishing corresponding groove flexible flange finite element model, using ANSYS surface treatment technologies, stressed bolt is extracted
Axle power, it is as shown in table 1 below with the comparison of non-groove flexible flange stressed bolt axle power.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
