At the same time, the pole tower sections are fixedly connected with the flange necks in insert and sticking modes, so that connection strength of the pole tower is guaranteed. The flanged joint structure for the composite pole tower is simple in structure, high in integral strength and suitable for electric power transmission.
Description
Technical field
The utility model relates to the composite material pole tower of carrying for electric power, particularly a kind of flange for composite material tower syndeton.
Background technology
At present, in the overhead transmission line comparatively the shaft tower of extensive use be mainly steel tube tower or angle steel tower, its height, width constantly increase along with the raising of electric pressure, not only expend land resources, increase electric energy loss, and when reply diastrous weather, be unfavorable for accident maintenance owing to weight is huge.For reducing the work transmission line cost of investment, economize the land resource, and eliminate impact that multiple flashover causes electric power netting safe running, at utmost reduce electric energy loss, the implementation of composite material pole tower is arisen at the historic moment.
Mostly composite material pole tower is take continuous glass fiber as reinforcing material, thermosetting resin is that matrix is prepared from, higher for the common shaft tower height of the higher composite material pole tower of electric pressure, be production and the cost of transportation of control composite material pole tower, need to adopt the multistage connecting method to connect.The conventional steel tower punches or the connected mode of welding and the splicing of composite material pole tower section is not suitable for postponing, because the continuity of destructible glass fiber causes local defect, thereby cause stress to be concentrated, greatly reduce the load load of composite material pole tower, had a strong impact on the reliability of transmission line of electricity safe operation.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, and a kind of simple in structure and flange for composite material tower syndeton that bonding strength is high is provided.
In order to realize above purpose, a kind of flange for composite material tower syndeton that the utility model provides, comprise the shaft tower section, flange by flanged neck between the adjacent described shaft tower section is connected and fixed, the tubular structure of described neck flange for matching with the link of described shaft tower section, neck flange is connected by the plug-in mounting mode with described shaft tower section, is provided with bonding agent between described shaft tower section and the described neck flange.By the flange with flanged neck each shaft tower section is connected into integral body, need not perforate or welding on the shaft tower section, guaranteed the intensity of shaft tower section; Simultaneously, the mode bonding with plug-in mounting is connected and fixed shaft tower section and neck flange, guaranteed the intensity that shaft tower connects; Simple in structure, bulk strength is high.
In such scheme, the internal diameter of described flange is less than the internal diameter of described shaft tower section link, and like this, the shaft tower section that is positioned at the flange top can be supported on the flange, has further guaranteed the bonding strength between shaft tower section and the neck flange.
In such scheme, be provided with reinforcing rib between described neck flange and the flange.
In such scheme, be respectively equipped with anti-turning round on the joint face of described shaft tower section and neck flange and take off line.
In such scheme, described bonding agent is thermosetting resin.
In such scheme, the link of described shaft tower section is inserted on the outer wall of described neck flange.
In such scheme, the link of described shaft tower section is inserted on the inwall of described neck flange.
The beneficial effects of the utility model are: by the flange with flanged neck each shaft tower section is connected into integral body, effectively avoided on the shaft tower section having guaranteed the intensity of shaft tower section because connect the local defect that causes; Simultaneously, the mode bonding with plug-in mounting is connected and fixed shaft tower section and neck flange, guaranteed the intensity that shaft tower connects; Simple in structure, bulk strength is high; And site operation is convenient.
