Problems solved by technology

[0002] In recent years, composite material transmission towers have gradually been recognized by the market and widely used due to their excellent characteristics such as light weight, high tensile strength and corrosion resistance; The connecting members such as the traditional metal or stainless steel still use the connecting members, and their structures are mostly U-shaped or runway-shaped; because the materials used for the composite transmission tower and the metal or stainless steel connecting members belong to two different materials, the steel The difference in degree and corrosion resistance is very large. At the same time, the U-shaped or runway-shaped connecting member has a single structure and only two connection points at both ends; when in use, the connecting member made of metal or stainless steel will be corroded due to climate change and environmental factors. The U-shaped or runway-shaped connecting member is easily deformed after being corroded, which will cause loosening between the connecting member and the fixed composite material cross arm or transmission pole, resulting in leakage or power failure, causing serious safety hazards to the transmission line, and also Limit the popularization and application of composite transmission towers

Embodiment Construction

[0027] Such as Figure 1-Figure 5 As shown, in the present invention, the adjustable elastic composite material connecting member is composed of a cylindrical connecting rod 1 that is prefabricated at one end with positive buckle male thread and with the other end prefabricated with reverse buckle male thread; The connection plates 2, 2'; and the U-shaped connection plates 3, 3' respectively connected to the free ends of the connection plates 2, 2' are assembled.

[0028] Wherein, the connecting rod 1 is a cylinder with a diameter of 40-100 mm and a length determined by the distance between the insulating rods connected to the connecting member, usually 150-1500 mm; one end of the cylindrical connecting rod 1 is prefabricated The positive buckle male thread and the other end prefabricated reverse buckle male thread; the length of the positive buckle male thread is the same as the length of the reverse buckle male thread, both 60-75mm; the tooth height of the thread is 2-3mm, t...

Abstract

The invention relates to a tightness-adjustable composite material coupling member and a fabrication method and an assembly of the coupling member. The coupling member is formed by assembling of a cylindrical connecting bar of which two ends are prefabricated with male threads, two connecting plates and two U-shaped connecting plates. The coupling member is characterized in that the connecting plates consist of cylindrical connecting rods and rectangular plates, and the two cylindrical connecting rods are in threaded connection with two ends of the cylindrical connecting bar; arc-shaped bosses are prefabricated on the upper surfaces and the lower surfaces of the connecting plates, and arc-shaped grooves corresponding to the arc-shaped bosses are prefabricated on the internal opposite surfaces of the U-shaped connecting plates; and the connecting plates are buckled and fixed into the arc-shaped grooves in the internal opposite surfaces of the U-shaped connecting plates in a screw-in manner through the arc-shaped bosses on the connecting plates so as to form the coupling member. The fabrication method of the coupling member comprises the following steps: Forming the male threads at the two ends of the cylindrical connecting bar; forming the connecting plates and the U-shaped connecting plates with the vacuum diversion process; and after the assembly, rotating the cylindrical connecting bar so as to adjust the tightness of the connecting plates at the two ends. The tightness-adjustable composite material coupling member has the characteristics of simple structure, easiness for operation, light weight, corrosion resistance, electric insulation and the like, and can be free of maintenance and conveniently popularized and applied.
