Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0019] Such as figure 1 , 2 As shown, the combined composite material cross arm includes a tie rod hoop 6 and a cross arm hoop 5 which are set on the shaft 3 in the upper and lower order, two cross arms 1, a tie rod 2 and a hanging point 4, wherein:

[0020] The cross-arm hoop 5 is composed of front and rear semicircle structures, and the two semicircles are hugged on the shaft 3 by pressing bolts. A hinge hole 51 and a hinge hole 52 are respectively provided on the front and rear semicircles.

[0021] The top of the hanging point 4 is provided with a pull rod connecting hole 41, the below of the hanging point 4 is provided with a wire clamp hanging hole 42, and the left and right ends of the hanging point 4 are respectively provided with a hanging point connecting hole 43,44, and the pull rod 2 The bottom end of the pull rod 2 links to each other with the hanging ...

Abstract

The invention relates to a combined form of composite cross arms, which comprises a draw bar hoop and a cross arm hoop, wherein the draw bar hoop and the cross arm hoop are sleeved on a bar body in an up-and-down sequence, the upper and lower surfaces of a hanging point are respectively provided with a draw bar connecting hole and a conductor grip hanging hole, the left and right ends of the hanging point are respectively provided with a hanging point connecting hole, the two ends of a draw bar are respectively connected with the hanging point and the draw bar hoop, the two ends of a cross arm are provided with a link fitting, one end of the cross arm is hinged with the cross arm hoop, the other end of the cross arm is connected with the hanging point through the hanging point connecting hole, and two cross arms are hinged through a hinging hole. According to the invention, a three-hanging-shaft connecting structure is fixedly formed among two cross arms and a cross arm hoop, and the stability of the three-hanging-shaft connecting structure is strengthened by using a draw bar, so that the problem that an insulating composite cross arm is relatively heavy in tooling fittings and inconvenient to install is solved, meanwhile, when the requirements on compression strength, tensile strength and stability are satisfied, the cross sectional area of the composite cross arm is reduced, the material consumption is reduced, and the project cost is greatly reduced.

Description

technical field [0001] The invention relates to a combined composite material cross arm. Background technique [0002] As an important connecting part connecting transmission towers and conductors, the composite material cross arm needs to have good structural characteristics and application performance. In order to ensure the mechanical strength, stiffness and structural stability of the composite material cross-arm under daily working conditions, it is usually necessary to select a composite material cross-arm with a larger cross-section to meet the requirements of the hanging net operation. The connection method between the composite material cross arm and the pole tower is usually to crimp the cross arm and the metal flange, and then fix it on the pole tower through the connection between the flange and the hoop. This method not only causes the installation of the composite material cross arm to be cumbersome, but also increases the weight of the composite material cros...
