Abstract
The utility model relates to a power transmission composite tower adopting lined steel pipe and pretightening force tooth connection and relates to the technical field of high-voltage power transmission line. The power transmission composite tower adopting lined steel pipe and pretightening force tooth connection comprises a composite pipe, a steel pipe, and a steel sleeve, wherein the steel pipe is lined at the joint of the composite pipe; the steel sleeve is arranged at the outer part of the joint of the composite pipe; outer thread is arranged at the place where the outer part of the composite pipe is connected with the steel sleeve; and inner thread is arranged on the inner surface of the steel sleeve. As composite connection between the lined steel pipe and the outer steel sleeve is adopted, inner resin can be effectively prevented from forming a through crack, anti-shearing strength of nodes is enhanced, deformation is limited, and bearing capability of nodes is improved.
Description
Technical field:
The utility model relates to ultra-high-tension power transmission line technical field, relates in particular to a kind of transmission of electricity complex pole tower.
Background technology:
It is the key position of composites structure design that composite material rod member connects, due to the feature of the fragility material of composite material own, cause the connecting portion weak link of structure stress often, therefore, the design and analysis of connecting portion is the most important thing of composites structure Design and Calculation, four kinds of connected modes that the common connected mode of composite material rod member mainly contains bolt connection, splicing, bolt one splicing mixing connection and pre-embedding metal part joint and is connected by joint.
Current power transmission tower structure is remained silent cross section as main with composite material rod member take annular, they mainly take glued joint and pre-embedding metal part joint as main, these two kinds of main pluses and minuses of mode have:
1) composite material pipe glueds joint, the connecting portion of cementing connecting rod has the advantages such as quality permanent deformation little, that cause is little, but glued joint non-dismountable, the unsustainable utilization of material, glued joint and generally need complete at factory, on-the-spot quality of glueing joint cannot obtain Reliable guarantee, and the bearing capacity of current domestic glue is lower, is difficult to meet the requirement for bearing capacity of complex pole tower and compound cross-arm.
2) pre-embedding metal part joint connects, this connected mode bearing capacity is higher, easy to connect, but comparatively complicated difficult of its technique, and this node discreteness is large, causes composite material tower body and cross-arm node often to do greatly and heaviness, leave larger margin of safety, whole like this composite material cross arm and conventional steel tower cross-arm weight are very nearly the same, composite material light weight, and advantage easy for installation cannot fully demonstrate.
Utility model content:
The purpose of this utility model is to provide the transmission of electricity complex pole tower that a kind of lined steel pipe is connected with pretightning force tooth, and it adopts lined steel pipe and overcoat steel sleeve composite joint, can effectively stop internal resin to form through crack, strengthens node shear strength.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises clad pipe, steel pipe, steel sleeve, in described multiunit tube joint place, be lined with steel pipe, multiunit tube joint place outer setting has steel sleeve, clad pipe is outside is provided with external screw thread with steel sleeve junction, and steel sleeve inner surface is provided with internal thread.
Described steel sleeve is made up of two semicircle steel bushings, and two semicircle steel bushings connect by draw-in groove on one side, are bolted on one side.
Lined steel pipe has the following advantages compared with cementing and conventional pre-embedding metal part joint with pretightning force tooth composite joint:
(1) supporting capacity of raising node, by coordinate the connected mode of pretightning force tooth outer steel sleeve pipe at compound termination lined steel pipe, outer and inner tube has formed certain effect of contraction to clad pipe, has limited distortion, applies pretightning force and has improved ultimate bearing capacity of joints.
(2) power transmission is reliable, easy to connect, and power transmission is clearly reliable, and lined steel pipe carries out cementing at factory and composite material, on-the-spotly only need carry out the bolt between steel pipe or be threaded, and this is identical with conventional steel structure, and technology maturation is convenient to Assembling.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, the transmission of electricity complex pole tower that lined steel pipe is connected with pretightning force tooth, it comprises clad pipe 1, steel pipe 2, steel sleeve 3, in described clad pipe 1 joint, be lined with steel pipe 2, clad pipe 1 joint outer setting has steel sleeve 3, clad pipe 2 is outside is provided with external screw thread with steel sleeve 3 junctions, steel sleeve 3 inner surfaces are provided with internal thread, steel sleeve 3 is made up of two semicircle steel bushings, two semicircle steel bushings connect by draw-in groove 4 on one side, be bolted on one side, in the time that the composite material pole tower of transmitting electricity connects, first by built-in steel pipe and clad pipe by plastic bonding, then steel sleeve is screwed into clad pipe junction along hand of spiral, finally tighten bolt, at this moment steel sleeve produces compressive stress to clad pipe, lined steel pipe produces pretightning force to clad pipe simultaneously, thereby effectively improve the bonding strength of junction, when dismounting, can also can directly open draw-in groove and directly steel sleeve is pulled down by unclamping bolt.
Claims (2)
1. the transmission of electricity complex pole tower that lined steel pipe is connected with pretightning force tooth, it is characterized in that, it comprises clad pipe, steel pipe, steel sleeve, in described multiunit tube joint place, be lined with steel pipe, multiunit tube joint place outer setting has steel sleeve, clad pipe is outside is provided with external screw thread with steel sleeve junction, and steel sleeve inner surface is provided with internal thread.
2. transmission of electricity complex pole tower according to claim 1, is characterized in that, described steel sleeve is made up of two semicircle steel bushings, and two semicircle steel bushings connect by draw-in groove on one side, are bolted on one side.
