Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1 to 4, the sectional cross arm shielding cover of the present invention is used for covering and connecting to the cross arm of the electric pole for insulation shielding, and is composed of four cover bodies, i.e., a left end cover 1, a left middle cover 2, a right middle cover 3 and a right end cover 4. Cover 2, right middle cover 3 and right-hand member cover 4 in the middle of the left end cover 1, the left side in proper order each other the concatenation form complete cover body structure, cover 3 and right-hand member cover 4 in the middle of the left end cover 1, the right side and the contact surface portion of the adjacent cover body are equipped with the buckle structure 5 that is used for connecting. The left end cover 1, the left middle cover 2, the right middle cover 3 and the right end cover 4 are respectively provided with a handle 6. Because the cross arm is located the top of pole, the utility model discloses a sectional type structure is favorable to carrying each subassembly respectively to cross arm department, and the operation degree of difficulty has been simplified on the cross arm to 5 concatenations of rethread buckle structure and cup joint, have promoted the operating efficiency.
The middle part of the contact surface of the left middle cover 2 and the right middle cover 3 is respectively provided with a semicircular electric pole interface, and the semicircular electric pole interface is provided with a surrounding structure 7. Two semicircular pole interfaces are spliced to form a complete pole interface, and the size of the pole interface is matched with the outer diameter of a pole. When each cover body of concatenation, cover 2 and cover 3 in the middle of the right side in the middle of the left side connect in the pole both sides through semi-circular pole interface card and realize the concatenation fixed, go on again and splice left end cover 1 and right end cover 4.
Insulator lead-out grooves 8 are respectively formed in the front end faces and the rear end faces of the left end cover 1 and the right end cover 4, semi-insulator lead-out grooves are respectively formed in the front end faces and the rear end faces of the contact portions of the left middle cover and the right middle cover, and the two semi-insulator lead-out grooves are spliced to form a complete insulator lead-out groove 8. Hanging points are arranged on two sides of the insulator leading-out groove 8, and an insulator hanging rod 9 is detachably hung on the hanging points. When the sectional cross arm shielding cover is installed in place, the insulator connected with the cross arm is connected with an external lead through an insulator leading-out groove 8; when the insulator is required to be subjected to more sliding operation in subsequent daily maintenance, the insulator hanging rod 9 is arranged on the hanging point, the insulator which is temporarily detached or installed and one section of the insulator connected with the cross arm is placed on the insulator hanging rod 9 for temporary lifting, so that the need that operators lift the insulator by manpower constantly is avoided, the operation flow is simplified, and convenience is provided for insulator replacement operation.
