Abstract
The utility model discloses a plug type power steel pipe pole which comprises a main pole, wherein the top of the main pole is provided with a cross arm. The main pole is formed by connecting at least two sections of hollow cone-shaped poles in an inserted mode. The top of a lower section cone-shaped pole is axially inserted into the bottom of an upper section cone-shaped pole to be fixed in a fitted mode. The plug type power steel pipe pole is a corner hollow cone-shaped pole. The lower section cone-shaped pole is inserted into the upper section cone-shaped pole to be fixed in a fitted mode. The connection mode is reliable in fixing, and a large number of reinforcing ribs are not needed to be arranged in a connection position. Accordingly, steel consumption of construction is reduced greatly, construction period is shortened, and construction cost is saved. In addition, the plug type power steel pipe pole is convenient to install, smooth in appearance, and convenient to transport and routinely maintain.
Description
Technical field
The utility model relates to the electric power transmission field, is specifically related to a kind of plug-in type power steel pipe rod.
Background technology
Steel pipe pole is widely used in the electric power transmission field, and power steel pipe rod generally has tens meters high, and high can reach tens of rice.Therefore steel pipe pole all adopts the more piece splicing construction from transportation and the convenient consideration of stable connection, existing steel pipe pole adopts flange form to connect, the link of two joint steel pipes is provided with the flange that cooperatively interacts, fix with bolted flange, also to weld the reliability that a large amount of floor guarantees connects around flange, and the welding job amount of floor is very large, and this has lengthened the cycle that steel pipe pole is installed on the one hand, has increased on the other hand steel using amount.And flange arrangement also easily deforms during floor in welding, be out of shape larger will produce waste product, and the sightless distortion of slight naked eyes also brings larger potential safety hazard to the use of steel pipe pole backward.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of plug-in type power steel pipe rod, and conservation is convenient to transportation and regular maintenance.
A kind of plug-in type power steel pipe rod comprises that the top is provided with the mobile jib of cross-arm, and described mobile jib is pegged graft by the conical hollow bar of two joints form at least, and the top axial of hypomere tapered rod is inserted the bottom of epimere tapered rod and fitted fixing.
The further improvement project of the utility model is that described mobile jib is the corner tapered rod that the cross section is regular polygon.
The utility model further improvement project is that the aperture of described mobile jib is along with increasing progressively gradually of height diminishes.
The utility model further improvement project is that the wall thickness of described upper and lower section tapered rod is identical or close.
The utility model compared with prior art has the following advantages:
Power steel pipe rod of the present utility model is the conical hollow bar of corner, the hypomere tapered rod axially inserts in the epimere tapered rod and fits, utilize the squeeze pressure of the tapering variation generation of rod member to fix, this connected mode is fixing reliably need to not arrange in the junction a large amount of ribs, greatly reduce the steel using amount of construction, saved construction duration and cost; Smooth transportation and the regular maintenance be convenient to of easy for installation, profile.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of plug-in type power steel pipe rod as shown in Figure 1 comprises that the top is provided with the mobile jib 1 of cross-arm 2, and described mobile jib 1 is pegged graft by two joint conical hollow bars and formed, and the top axial of hypomere tapered rod 11 is inserted the bottom of epimere tapered rod 12 and fitted fixing.
Still described mobile jib 1 is the corner tapered rod of octagon for the cross section as shown in Figure 1, and the aperture of described mobile jib 1 is along with increasing progressively gradually of height diminishes.
Still as shown in Figure 1, described upper and lower section tapered rod 12,11 wall thickness are identical, concrete size increases or reduces according to the size of varying environment lower stress, and wherein the hypomere tapered rod inserts the interior length of epimere tapered rod between the safe length of installation dimension, guarantees fixing reliability.
