Abstract
The utility model discloses a kind of steel pipe pole locking devices, the steel pipe pole includes the rhabodoid that several are sequentially connected end to end, the two adjacent rhabodoids are connected by fastening assembly, on Yu Suoshu steel pipe pole and are located at the Buffer Unit being fixed with respectively at each fastening assembly for offsetting alternating stress load.The utility model has the characteristics that alternate stress suffered by steel pipe pole can be offset and avoids the loosening of steel pipe pole junction, the anti-loosening and maintenance area suitable for steel pipe pole.
Description
Technical field
The utility model belongs to field of electrical equipment, specifically, being related to a kind of steel pipe pole locking device.
Background technique
The connection type of current power transmission line steel pipe rod is mostly using flanged joint.When using flanged joint, upper section
Bottom flange is to be connect by the fastening force of bolt to realize with lower section top flange.It is whole to make several segments connect into a rigidity
Body, steel pipe pole is in prolonged be on active service, and since each moment can be acted on (such as wind load) by alternate stress, bolt exists at this time
Loosening can be generated under the action of alternate stress.
For power transmission line steel pipe rod in long service, bolt looseness is the largest security risk, once maintenance is not in time,
Serious accident will be will cause, to guarantee its safety used, operation power department is needed regularly to be safeguarded, examined
Look into, and formulate security maintenance scheme, annual maintenance plan, maintenance capital investment plan etc..Need to put into biggish manpower and material resources,
Also to have a professional construction team.
Utility model content
The utility model provides one kind and can offset alternate stress suffered by steel pipe pole and steel pipe pole junction is avoided to loosen
Steel pipe pole locking device.
To achieve the above object, technical solution used by the utility model is as follows:
A kind of steel pipe pole locking device, the steel pipe pole include the rhabodoid that several are sequentially connected end to end, and two is adjacent
The rhabodoid by fastening assembly be connected, on Yu Suoshu steel pipe pole and be located at each fastening assembly at be connected respectively it is useful
In the Buffer Unit for offsetting alternating stress load.
Preferably, the fastening assembly is included in the top flange and bottom method that the rhabodoid of adjacent two sets up separately by proximal end
Orchid, and the top flange and bottom flange are fixed by several bolts.
Preferably, the Buffer Unit includes the circumferential direction along the steel pipe pole equably set on the two adjacent rhabodoids
Between tie unit.
Preferably, the tie unit is three.
Preferably, the tie unit includes being divided on the two adjacent rhabodoids and the lifting lug of corresponding setting,
Tightening has prestress wire between the two corresponding lifting lugs.
The utility model is due to using above-mentioned structure, and compared with prior art, acquired technological progress is:
The two adjacent rhabodoids are fixedly connected by fastening assembly, and the Buffer Unit is set on the steel pipe pole and is located at two
It is described tight when external force (such as wind-force) acts on the steel pipe pole at the fastening assembly of the adjacent rhabodoid junction
Gu the external force that component is subject to is offset by the Buffer Unit, and fastening assembly is avoided to be caused steel pipe pole each by alternating stress load
It is loosened between the rhabodoid, and then leads to the generation of accident.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.
In the accompanying drawings:

Fig. 2 is the schematic enlarged-scale view in the portion A in Fig. 1；
Fig. 3 is the layout drawing of tie unit described in the utility model embodiment.
Component: 1- steel pipe pole, 2- rhabodoid are marked, 3- pushes up flange, the bottom 4- flange, 5- bolt, 6- lifting lug, 7- prestress steel
Twisted wire, 8- tie unit.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model.It should be appreciated that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment steel pipe pole locking device
Present embodiment discloses a kind of steel pipe pole locking devices, and as shown in Figure 1, 2, steel pipe pole 1 is fixed on ground vertically
On, and steel pipe pole 1 is made of multiple rhabodoids 2 connect that successively join end to end, two adjacent rhabodoids 2 are solid by fastening assembly
It is scheduled on together.The present embodiment in order to facilitate the installation of and maintenance, the top of underlying rhabodoid 2 in two adjacent rhabodoids 2
End is welded with top flange 3, and the bottom end for the rhabodoid 2 being located above is welded with bottom flange 4, push up flange 3 and bottom flange 4 fit and
It is uniformly arranged and runs through along the circumferential direction of top flange 3 or bottom flange 4 by multiple bolts 5, top flange 3 and bottom flange 4 are fastened.
The present embodiment in order to avoid when bearing alternating stress load, the bolt 5 of fastening assembly becomes to loosen steel pipe pole 1,
On steel pipe pole 1 and it is located at the Buffer Unit being fixedly connected with respectively at each fastening assembly for offsetting alternating stress load.Its
In, Buffer Unit includes being evenly provided on tie unit 8 between two adjacent rhabodoids 2 along the circumferential direction of steel pipe pole 1, such as
Shown in Fig. 3, tie unit 8 is three.Each tie unit 8 is on two adjacent rhabodoids 2 and corresponding including being respectively welded at
The lifting lug 6 of setting, tightening has prestress wire 7 between two corresponding lifting lugs 6, and prestress wire 7 mostly uses steel
Cord, the both ends of wirerope are separately fixed on two corresponding lifting lugs 6, and wirerope is in tension at this time.
The working principle of the utility model embodiment is as follows:
Firstly, being fixed by fastening assembly by adjacent rhabodoid 2；Later, the prestress steel twist of Buffer Unit is tightened
Line 7, then steel pipe pole 1 is assembled and is fixed on the ground vertically.When external force is on steel pipe pole 1, two adjacent bars
When fastening assembly stress between shape body 2, the prestress wire 7 of Buffer Unit offsets most of external force, and then avoids steel
The bolt 5 of the fastening assembly of tube rod 1 loosens, and causes the generation of safety accident.The utility model embodiment was produced in steel pipe pole 1
Cheng Zhongke greatly reduces line service, can also reduce the investment of maintenance fund.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of the utility model claims protection.
