Description

A kind of composite material pole tower that has the frock connector
Technical field
The utility model belongs to the transmission line of electricity field, is specifically related to a kind of composite material pole tower that has the frock connector.
Background technology
Using comparatively widely in the at present domestic and international overhead transmission line, shaft tower mainly contains several classes such as concrete frame and iron tower.The transmission line of electricity of China 110kV and above electric pressure adopts iron tower more, iron tower has exposed a lot of defectives and problem demanding prompt solution in the use, as the build heaviness, installation cost is higher, maintenance cost is bigger, and thunder and lightning, ice and snow, dense fog, atmosphere pollution all can threaten to the safety transmission of electricity of traditional shaft tower.
Fiber-resin composite has specific strength, specific modulus height; Excellent insulation performance; Designability can be good; Characteristics such as fatigue performance is good, use composite material manufacturing electric power line pole tower and have special advantages at aspects such as ensureing transmission line of electricity security of operation, minimizing circuit width of corridor, reduction maintenance cost and low-carbon emission, composite material pole tower has become the desirable substitute of generally acknowledged traditional shaft tower both at home and abroad.
The frock mode of the cross-arm of existing iron tower and shaft adopts punching, welding manner.After adopting composite material as overhead line structures, rethink the frock problem, the frock mode of composite material pole tower cross-arm adopts anchor ear more both at home and abroad at present, modes such as punching, this frock mode is many to be used in the low-voltage grade, in addition owing to the fiber of composite material is arranged continuously, if punching can make the mechanical property of material be affected, make the shaft tower discontinuity, and then influence the application life of shaft tower.
Summary of the invention
The purpose of this utility model be propose a kind of make transmission line of electricity adopt composite insulating pole tower after, can make full use of the advantage of composite material, avoid because frock influences the whole mechanical property of shaft tower and the composite material pole tower that has the frock connector of whole tower mechanical structure.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of composite material pole tower that has the frock connector, comprise and adopt insulating composite material to make shaft tower and cross-arm, be characterized in: the shaft tower body of the tower is provided with built-in connection, be provided with the metalwork of flanged dish at composite material cross-arm root, the composite material cross-arm is connected on the shaft tower body of the tower by the metalwork and the built-in connection of flanged dish, and cross-arm and shaft tower body of the tower form integrated.
Built-in connection is made of by connector and built-in fitting flange connecting dish built-in fitting and one on the described shaft tower body of the tower, and the flange in the built-in connection is connected with the metalwork of flanged dish in the composite material cross-arm.
On the flange of flanged (FLGD) metalwork neck flange is set in the described composite material cross-arm, the root of composite material cross-arm is arranged in the described neck flange.
Also twine binding between described composite material cross-arm and the described shaft tower body of the tower by fiber.
Built-in fitting in the described built-in connection is provided with groove, and the fiber of described winding binding twines by groove.
The beneficial effects of the utility model are:
(1) can under the precondition that guarantees mechanical strength, avoid bolt in the shaft punching, destroy the shaft fiber architecture, reduce the shaft mechanical performance.
(2) have groove on the built-in connection, make the fiber that twines binding can better strengthen the reinforcing of built-in connection and shaft, can also strengthen the mechanical strength of built-in connection and cross-arm connecting portion in addition.
(3) avoid not having under the situation of neck flange, the cross-arm root has the situation that stress is concentrated.
(4) improve cross-arm vertically, mechanical performance longitudinally, and can effectively reduce the sectional dimension of composite material cross-arm, save material, increase economic efficiency.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model built-in connection.
Fig. 3 is the lateral view of Fig. 2.
Fig. 4 is the structural representation of the metalwork of the flanged dish of the utility model.
Fig. 5 is the lateral view of Fig. 4.
Among the figure: the metalwork of 1-shaft tower body of the tower, 2-composite material cross-arm, 3-built-in connection, the flanged dish of 4-, the flange in the 31-built-in connection, the connector in the 32-built-in connection, the built-in fitting groove in the 33-built-in connection, 41-neck flange.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model relates to a kind of composite material pole tower that has the frock connector, the utility model is processed into the built-in connection 3 (Fig. 2) of an integral body with built-in fitting 33 and flange 31 by connector 32, by built-in process built-in fitting 33 is fixed on the shaft tower body of the tower.The technique effect that brings thus is at least: can make shaft and built-in fitting be equivalent to an overall structure, mechanical strength is good.The root of composite material cross-arm 2 is connected with the metalwork of flanged dish 4, on the flange of the metalwork 4 of flanged dish, designed certain-length neck flange 41, the technique effect that brings thus is to avoid composite material cross-arm 2 Root Stress to concentrate at least, make composite material cross-arm root stressed evenly, mechanical performance improves.
As shown in Figure 1, the flange in the metalwork 4 of flange in the built-in connection 31 and flanged dish is coupled together with fastening bolt, used bolt quantity is determined by moment of flexure.Such frock mode is avoided punching on cross-arm and shaft, has increased the operability of installing, and has guaranteed the safety of installing simultaneously.Also twine binding between composite material cross-arm 2 and the shaft tower body of the tower 1 simultaneously by fiber.
The content that is not described in detail in this manual belongs to this area professional and technical personnel's known prior art.
