Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

The auxiliary connecting piece for the power transmission line in emergency repair aims to provide an auxiliary connecting piece which is used in emergency and used for stabilizing a connecting node of the power transmission line, the connecting piece is composed of four parts, namely a female cylinder 1, a driving group 2, a sub-cylinder 3 and a primary-secondary clamp structure, and the specific structure and the using method are as follows.

The structure of the female cylinder 1 is a cylinder structure as shown in fig. 3, two ends of the female cylinder 1 are provided with end cylinders 6 with the aperture smaller than that of the female cylinder 1, and the end cylinders have two functions, namely, a screw 10 for installing the driving group 2 and a movable range of a movable seat 13 for limiting the installation on the screw 10.

The driving group 2 is installed inside the female cylinder 1 in a specific way as shown in fig. 2. The driving group 2 is composed of a nut 9, a screw 10, a movable seat 12 and a pull rod 13. The screw 10 is mounted on the end tube 6 at both ends of the female tube 1, and a nut 9 is provided at one end of the screw 10, and the rotation of the screw 10 is driven by the rotation of the nut 9.
