Abstract
The utility model relates to a wire pole that the power transmission was used is less to the current unreasonable bearing capacity of steel pipe pole structure atress and a steel pipe pole that provide. Including upper boom and lower beam, the lower beam include the connecting portion of being connected with the upper boom, the lower beam still is the left supporting part and the right supporting part of axial symmetry setting including the center of using connecting portion as the center, flange joint is passed through to left supporting part, right supporting part and connecting portion formula structure as an organic whole between upper boom and the lower beam. Is contained angle between left side supporting part and the right supporting part 10 90 between arbitrary numerical value. Install the cross arm on the upper boom. The utility model discloses a " point " type structure converts traditional steel pipe pole's bottom moment of flexure to axle power, make full use of material tensile (resistance to compression) intensity, and the structure is more reasonable. The utility model discloses reducing the steel quantity, having improved structural stiffness simultaneously, under the same exogenic action, the peak of the staff amount of deflection reduces greatly. The utility model discloses processing, simple to operate.
Description
Technical field
This utility model belongs to the electric pole of power transmission, more particularly, to a kind of steel pipe pole.
Background technology
Under the existing overall situation in Present Economical high speed development, power transmission and transformation capacity is increasing, leads with heavy in section
Line, big span use, and conventional steel bar (taper steel pipe pole) is more and more uneconomical, or can not be continuing with, and propose new steel pipe
Bar structural shape is extremely urgent.
At present, 35kv, 110kv, 220kv power transmission steel pipe pole primary structure pattern is cantilever design, and broad form is single steel
Tubular construction form.Said structure weaknesses analysis are as follows:
Structure stress is unreasonable, uses with large-section lead, big span, load is increasing, in order to meet intensity and
Amount of deflection requires, and conventional steel bar section, wall thickness greatly increase, and economy is poor.Processing, installation difficulty are big.
Utility model content
The purpose of this utility model is one kind that is less for the unreasonable bearing capacity of existing steel tube rod structure stress and providing
Steel pipe pole.
To achieve these goals, technical solution adopted in the utility model is:
A kind of steel pipe pole, including upper boom and lower beam, described lower beam includes the connecting portion being connected with upper boom, and lower beam also includes
The left support portion axisymmetricly being arranged centered on the center of connecting portion and right support portion, left support portion, right support portion and connection
Portion is integral type structure, is connected by flange between upper boom and lower beam.
It is provided with flange at the right support subordinate end of the left support portion of lower beam and lower beam.
Angle between described left support portion and right support portion is any value between 10 ° -90 °.
Angle between described left support portion and right support portion is preferably 45 °.
Cross-arm is provided with upper boom.
The connecting portion of described lower beam to left support portion and right support part between width be gradually increased.
The face that described cross-arm installation direction is formed with left support portion and right support portion be arranged in parallel.
Lightning arrester is provided with upper boom, lightning arrester is directly turned on ground from two supporting parts inside of lower beam.
The beneficial effects of the utility model: this utility model adopts " sharp " type structure, by the bottom moment of conventional steel bar
It is converted into axle power, makes full use of material tension (resistance to compression) intensity, structure is more reasonable.This utility model reduces rolled steel dosage, with
When improve the rigidity of structure, under the effect of identical external force, masthead amount of deflection greatly reduces.This utility model processing, easy for installation.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to embodiment, this utility model is described further.
Embodiment
A kind of steel pipe pole as shown in Figure 1, includes lower beam and the upper boom 1 being connected with cross-arm 2, described lower beam include with upper
The connecting portion 3 that bar connects, lower beam also includes the left support portion 4 axisymmetricly arranging centered on the center of connecting portion and right support
Portion 5, left support portion, right support portion and connecting portion are integral type structure, and lower beam connecting portion is connected by flange 6 with upper boom.Under
The right support subordinate end of the left support portion of bar and lower beam is provided with flange.Angle between described left support portion and right support portion is
Any value between 10 ° -90 °.Angle between described left support portion and right support portion is preferably 45 °.Described lower beam
Connecting portion to left support portion and right support part between width be gradually increased.Described cross-arm installation direction and left support
The face that portion and right support portion are formed be arranged in parallel.Lightning arrester is provided with upper boom, lightning arrester is from two supporting parts of lower beam
Inside is directly turned on ground.
Lower beam is designed to the structure of left and right supporting part by this utility model, and this structure mounting stability is strong, with traditional list
Bar is compared, and underground mounting fixing parts depth and intensity are substantially reduced, thus reducing cost, compared with traditional single pole, same carrying
Under power, the diameter of steel pipe pole can reduce, and reduces cost further, and installation effectiveness can improve in a large number.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, in the art commonly
The simple change of technical staff and replace be all within protection domain of the present utility model.
