During installation, the two anchor rings 22 corresponding to each other limit the moving range of one sleeve 23, so that slipping of the sleeve 23 and the steel wire rope 21 in the conveying process is avoided, the conveying of pressure steel pipes is influenced, the inclined planes are arranged at the ends of the two annular rings in a group, the friction resistance is favorably reduced, and clamping stagnation is avoided.

In the use process, the sleeve 23 is in contact friction with the circular linear hole of the linear groove 14, the sleeve 23 can expand, and when the sleeve 23 expands, the notch of the expansion groove contracts, so that clamping stagnation is avoided.

When the device is used, the brake mechanism of the winch 32 is used for controlling the movement of the conveying line 2, the winch 32 is used for controlling the release speed of the conveying line 2, and the phenomenon that the conveying speed is too high and the installed pipe joints are violently collided is avoided.

The above-described embodiments are merely preferred embodiments of the present invention, and should not be construed as limiting the present invention, and features in the embodiments and examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
